it should be further noted that, in order to ensure safety, the present invention may be configured with a safety valve 23 (as shown in fig. 11 and 12) on the handle 2 or/and the tailstock 3, where the safety valve 23 may be composed of a valve ball 23a and an adjusting spring 23b, where the position of the safety valve 23 is optimally disposed between the adjusting valve 4 and the pressure chamber a of the tailstock 3, the safety valve 23 intersects with the air pressure chamber a of the tailstock 3 and has a bypass passage communicating with the external atmosphere, and in case of normal safety operation, the adjusting spring 23b presses the valve ball 23a to block the bypass passage communicating with the external atmosphere via the safety valve 23 (as shown in fig. 11 and 12), but when the gas pressure in the pressure chamber a is too high and is unsafe, the gas in the air pressure chamber a communicating with the pressure chamber a and intersecting with the safety valve 23a pushes the valve ball 23a to press the adjusting spring 23b to bypass the external atmosphere (not shown in the figure), so that the gas pressure in the pressure chamber a is released to play the purpose of ensuring safety, and the safety valve 23b is activated, and if the pressure chamber 23a is preset by the pressure chamber a, the pressure chamber 23b is communicated with the bypass passage, and the pressure chamber a is set by the preset threshold, and the pressure chamber a, and the preset by the pressure chamber 23 b; the function of the air inlet valve of the invention is to regulate and control whether the air inlet channel 2a is in a selected passage state or a selected disconnection state, when the air inlet valve controls the air inlet channel 2a to select the passage state, external high-pressure gas starts to enter the air pressure cavity A of the tail seat 3 and becomes power for extruding ointment working medium in the ointment cylinder 5: referring to fig. 2, at this time, the trigger 7b is touched by the hand of the operator → the push rod 7c is pressed and moved against the elastic force of the push spring 7g → the push rod 7c touches and presses the sealing valve 7e and further presses the return spring 7f → the return spring 7f is compressed and then the sealing valve 7e is detached from the sealing valve seat 7d → the sealing passage between the sealing valve 7e and the sealing valve seat 7d is opened → external high-pressure gas enters the air pressure chamber a in the tailstock 3 via the air intake passage 2 a; when the air inlet valve selectively controls the air inlet channel 2a and makes it to be in the open circuit state, the external high-pressure air stops entering the air pressure cavity A of the tailstock 3: referring to fig. 3, at this time, the operator releases his or her hand from pressing the trigger 7b → the rod 7c moves under the action of the spring force of the top spring 7g and forces the trigger 7b to return, and at the same time, the return spring 7f presses the sealing valve 7e against the sealing valve seat 7d → the sealing channel between the sealing valve 7e and the sealing valve seat 7d is closed → the external high-pressure gas stops entering the air pressure chamber a in the tailstock 3; it should be noted that the air release valve and the air intake valve of the present invention, which can be controlled in a coordinated manner, are embodied such that the air release passage 2b is opened when the air intake passage 2a is opened (see fig. 13), and the air release passage 2b is opened when the air intake passage 2a is opened (see fig. 14). The using conditions of the invention are as follows: 1) In the preparation operation, the bearing pull rod 1 is firstly turned to a preparation operation position (as shown in fig. 3 and 4), the rod body of the bearing pull rod 1 is restrained by the first concave-convex structure 3a and is maintained at the position (so that enough space position is left without preventing the cream tube 5 from being loaded into the tail seat 3), and then the cream tube 5 is inserted into the tail seat 3 to be in initial sealing contact with the sealing element 6; 2) During the extrusion operation, the force-bearing pull rod 1 which is originally in the preparation operation position is pulled up to the extrusion operation position (as shown in fig. 1 and fig. 2), then the force-bearing pull rod 1 is telescopically adjusted relative to the tailstock 3, the clamping structure 1a of the force-bearing pull rod 1 is clamped to the paste barrel 5 or other parts (such as a gun nozzle 12) which are clamped and fixedly connected to the paste barrel 5, then the related locking parts (such as the thread structure 1c arranged on the support leg 1b of the force-bearing pull rod 1 and the adjusting nut 1d arranged on the thread structure) are adjusted to firmly press the paste barrel 5 against the tailstock 3, after all operations are prepared, an operator can touch the trigger 7b of the air inlet valve to enable the air inlet channel 2a to be in a passage state, at the moment, the externally connected high-pressure gas can enter the air pressure cavity a in the paste barrel 3 through the air inlet channel 2a and form a main sealing force to enable the sealing element 6 to be tightly sealed and attached to the paste barrel 5, and the high-pressure sealing force sealing medium in the paste barrel 5 can be guided to an external air-opening sealing area through the air inlet channel 7b to be in a non-opening state, so that the paste barrel is not to be discharged to the paste barrel 3, and the high-pressure sealing medium is not to be discharged to the gun, and the high-pressure sealing area when the high-pressure sealing effect of the gun is achieved, and the high-pressure sealing element is achieved, and the high-pressure sealing device is achieved, and the high-pressure sealing area, and the high-pressure sealing device is achieved; 3) After the ointment medium in one ointment cylinder 5 is squeezed out, the force-bearing pull rod 1 can be wrenched to a preparation operation position, and then the used ointment cylinder 5 is taken out and replaced by a new ointment cylinder 5; 4) When the glue gun is folded and carried, the bearing pull rod 1 can be turned and is free from the restraint of the second concave-convex structure 3b and the first concave-convex structure 3a, and the bearing pull rod 1 is in a position close to the handle 2 (see fig. 5 to 8). A third structural feature of the present invention is that a part of the air release channel 2b is disposed on the shaft of the ejector 7c, and in addition, a part of the air release channel 2b shares a channel with the air inlet channel 2a, where the ejector 7c can be made hollow to form a part of the air release channel 2b (as shown in fig. 11 to 14) or can be made slotted on the shaft of the ejector 7c to form a part of the air release channel 2b (not shown in the figures), and for easy identification, the channel shared by the air release channel 2b and the air inlet channel 2a is labeled as (2a, 2b); the air release passage 2b is closed while the air intake passage 2a assumes an on-state (as shown in fig. 13) when the trigger 7b presses the jack 7c and causes the jack 7c to press against the sealing valve 7e and forces the sealing valve 7e to compress the return spring 7f away from the sealing valve seat 7d, the air release passage 2b is opened while the air intake passage 2a assumes an off-state (as shown in fig. 14) when the sealing valve 7e is pressed against the sealing valve seat 7d by the return spring 7f and/or the gas pressure and the jack 7c is disengaged from the sealing valve 7e by the top spring 7g and/or the gas pressure; it should be noted that when the air release passage 2b is opened, the air in the air pressure chamber a of the tailstock 3 is communicated with the external atmosphere, and at this time, the air pressure in the air pressure chamber a is rapidly reduced, in response, the glue gun can be immediately stopped to extrude the paste medium in the paste cylinder 5 to the outside, that is, the extrusion operation can be stopped at an interruption, as is well known, the glue gun must be stopped at an interruption when the output is required to be stopped, so as to avoid the phenomena of adhesion, excess and the like which affect the effect and quality of the extrusion operation, at this time, the air supply passage 2a is closed to stop supplying air to the tailstock 3, but the high-pressure air remaining in the air pressure chamber a still continues to expand, and if the air gun is not unloaded in time, the glue gun will continue to extrude the paste body to the outside in an out-of-control manner, to avoid such a phenomenon, referring to fig. 14, the operator releases his/her hand to not press the trigger 7b → the rod 7c is moved by the spring force of the spring 7g and forces the rod 7c to separate from the sealing valve 7e (meanwhile, the return spring 7f presses the sealing valve 7e against the sealing valve seat 7d to close the air inlet channel 2a to stop the external high pressure air from entering the tailstock 3) → the air outlet channel 2b in the rod 7c is opened → the residual air in the air pressure chamber a in the tailstock 3 leaks to the outside through the air outlet channel 2b (shared channel) on the handle 2 (or the tailstock 3) and the air outlet channel 2b on the rod 7c and rapidly balances the pressure of the tailstock and the external atmospheric pressure → the residual air in the tailstock 3 loses the driving ability, so that the glue gun rapidly stops the external jet; it should be noted that, during the extrusion operation, the operator pulls the trigger 7b to press the top rod 7c and move it against the elastic force of the top spring 7g → the top rod 7c touches and presses the sealing valve 7e (see fig. 13) → the air release passage 2b in the top rod 7c is closed to stop releasing air to the outside → the air pressure in the air pressure chamber a of the tail seat 3 can be normally established, so that the glue gun can normally perform the extrusion operation.
Further, the force-bearing pull rod 1 of the invention has a structure of double legs 1b, and the two legs 1b are respectively arranged beside the two sides of the tail seat 3 (as shown in fig. 8), so that the arrangement has the advantages of strengthening the strength of the force-bearing pull rod 1 and simultaneously being convenient for arranging the position for placing the cream tube 5. In addition, the leg 1b of the force bearing pull rod 1 can be rotatably matched with the tailstock 3 through a rotating pin 8 (see fig. 1-8 and 10-18), and particularly, the rotating pin 8 can be made into a hollow structure (not shown) for reducing weight. The pivot pin 8 of the present invention may be provided with two through holes 8a (see fig. 1, fig. 3 and fig. 5), wherein the two legs 1b of the force-bearing pull rod 1 can respectively pass through and slidably fit with the two through holes 8a, and here, the through holes 8a may be in the form of a complete hole structure (as shown in fig. 1, fig. 3 and fig. 5) or in the form of an open slot (not shown), and in addition, the two through holes 8a are preferably in the form of radial holes with respect to the pivot pin 8, because the manufacturing process, the assembling process and the operability can be better. In order to adapt to the cream cylinders 5 with different specifications, the tail ends of the supporting legs 1b can be provided with thread structures 1c and provided with corresponding adjusting nuts 1d (see fig. 1-8 and 10-18), so that the bearing pull rods 1 can be adjusted according to the cream cylinders 5 with different lengths and specifications.
Further, the sealing element 6 of the present invention may be configured as a ring structure and include a tapered hole structure (see fig. 11, 12 and 15), which is advantageous in accommodating the cream cylinders 5 (see fig. 15) with different diameter specifications on the one hand and in sealing between the cream cylinder 5 and the tail seat 3 on the other hand, and particularly, in more effectively utilizing the gas pressure in the gas pressure chamber a in the tail seat 3 to form a strong main sealing force.
In order to effectively position and restrain the bearing pull rod 1, a second limit stop 3c can be arranged above the tail seat 3 adjacent to the second concave-convex structure 3b, and a first limit stop 3d can be arranged below the tail seat 3 adjacent to the first concave-convex structure 3a (see fig. 1 to 9), wherein the upper part refers to that the handle 2 is held at the plumb position, the second limit stop 3c is arranged above the second concave-convex structure 3b, and the first limit stop 3d is arranged below the first concave-convex structure 3 a.
In order to smoothly convert different working states of the bearing pull rod 1, the bearing pull rod 1 designed by the invention has the following properties or structures: the force-bearing pull rod 1 spans a first concave-convex structure 3a, a second concave-convex structure 3b or a first limit stop 3d by means of elastic deformation or an obstacle crossing structure 1e arranged on a supporting leg 1b of the force-bearing pull rod 1, and accordingly conversion among a preparation operation position, an extrusion operation position and a retraction storage position of the force-bearing pull rod 1 is completed, wherein the elastic deformation is realized by slightly pulling the force-bearing pull rod 1 to enable the force-bearing pull rod 1 to generate certain elastic deformation under the condition that the first concave-convex structure 3a, the second concave-convex structure 3b or the first limit stop 3d are restrained and finally get rid of the restraint of the deformation, and the obstacle crossing structure 1e is an obstacle avoiding structure, and the position of the force-bearing pull rod 1 can be adjusted by stretching and retracting the force-bearing pull rod 1 and the obstacle crossing structure can be aligned to a structure needing to span, such as the first concave-convex structure 3a, the second concave-convex structure 3b or the first limit stop 3 d.
The fourth characteristic of the invention is that the invention can achieve 'soft and hard eating-through', namely, the same glue gun is used, the invention can be suitable for the extrusion operation of the plaster cylinder 5 packaged by hard shell and the extrusion operation of the plaster cylinder 5 packaged by soft shell, while the traditional glue gun can only be suitable for the extrusion operation of one kind of plaster cylinder 5, therefore, the invention greatly expands the application objects and the application range of the glue gun, therefore: the multi-station convertible handle-operated pneumatic glue gun of the force-bearing pull rod 1 of the present invention can be provided with a detachable barrel casing 9, a detachable piston 10, a detachable front cover 11 and a detachable gun nozzle 12 (as shown in fig. 16 to 18), wherein the piston 10 can be arranged in the barrel casing 9 and can be in movable sealing fit with the inner wall surface of the barrel casing 9, the gun nozzle 12 is provided with a hollow flow passage 12a and is fixedly connected to the front end of the barrel casing 9 by the front cover 11, the rear end of the barrel casing 9 can be inserted into the tailstock 3 and can realize sealing between the barrel casing 9 and the tailstock 3 by contact fit with the sealing element 6, the front end of the barrel casing 9, the front cover 11 or the gun nozzle 12 can be clamped on the clamping structure 1a of the force-bearing pull rod 1, and herein, the front end and the rear end refer to: one end of the tail seat 3 is the rear end under the working condition of extrusion operation, and the other end of the tail seat facing the glue gun to discharge the ointment working medium under the working condition of extrusion operation is the front end; obviously, the invention can realize that the soft paste working medium is output outwards from the flow channel 12a of the gun nozzle 12 to the target extrusion operation area by configuring the cylinder shell 9, only plugging the soft-packaged paste cylinder 5 into the cylinder shell 9, then driving the piston 10 by air pressure, and then extruding the paste cylinder 5 by the piston 10; with regard to the plaster barrel 5 packaged by the hard shell, the extrusion operation can be performed by only directly installing the plaster barrel 5 into the tail seat 3 and arranging and adjusting the position of the bearing pull rod 1 as described above.
The fifth great characteristic of the invention is that: the glue gun device is provided with a bag breaking member 13, the bag breaking member 13 can be a separate member and is attached to the gun nozzle 12 (not shown in the figures) or the bag breaking member 13 and the gun nozzle 12 are made into an integral structure (as shown in fig. 18 and 19), the bag breaking member 13 is provided with a sharp-pointed or knife-pointed barrier structure 13a, and the sharp point or the needle point of the barrier structure 13a faces to the direction opposite to the outflow direction of the gun nozzle 12; as is well known, in the conventional pneumatic glue gun facing the soft package paste tube 5, the paste tube 5 must be cut in advance, that is, an opening is cut in advance at one end of the paste tube 5 so that the paste working medium in the paste tube 5 can be squeezed out, and at this time, one end of the cut must be directed to the gun nozzle 12 side when placing the paste tube 5 (as shown in fig. 16 and 17), which not only reduces the efficiency of the squeezing out operation, but also easily causes the paste working medium in the paste tube 5 to run off at the cut, and dirts the hands of the operator or the working site; after the bag breaking member 13 is arranged, the working medium efficiency can be effectively improved, and the operation comfort is improved: firstly, the preliminary procedure of cutting the opening can be avoided, and secondly, the cream tube 5 can be placed cleanly without being divided into a front end and a rear end (only by being directly inserted into the tube shell 9); the working principle of the bag breaking member 13 is as follows: the high-pressure gas in the pressure chamber A in the tailstock 3 pushes the piston 10 to slide along the inner wall of the barrel shell 9 → the piston 10 is extruded to the paste barrel 5 which is placed in the barrel shell 9 in advance and pushes the paste barrel 5 to slide towards one side of the gun nozzle 12 → the packaging bag shell of the paste barrel 5 is collided with the barrier structure 13a which is arranged on the upper face and is punctured → the piston 10 continuously pushes the paste barrel 5 and extrudes the paste barrel to force the paste working medium in the paste barrel to be extruded → the extruded paste working medium is output to the target extrusion operation area from the hollow flow passage 12a of the gun nozzle 12. Furthermore, the bag breaking structure 13 is provided with a passage 13b (see fig. 18 and 19) communicated with the flow passage 12a of the gun nozzle 12, so that the ointment working medium in the ointment tube 5 can be more smoothly led out. Still further, the bag breaking means 13 of the present invention may be disposed offset with respect to the axis O2 of the cartridge housing 9 (see fig. 18), so that the arrangement is such that the bag breaking means 13 is free from the packing button of the cartridge 5 (the inclusion button is generally located at the central portion of the cartridge 5), thereby increasing the life of the bag breaking means 13; in addition, the cross section of the bag breaking structure 13 may be crescent-shaped (see fig. 18 and 19), that is, the bag breaking structure 13 is a structure that semi-surrounds the ring cloth axis O2, so that the strength and rigidity of the bag breaking structure 13 can be increased, and the service life of the bag breaking structure 13 can also be prolonged.
Compared with the prior art, the invention has the outstanding advantages that: by adopting the structural scheme that the first concave-convex structure 3a and the second concave-convex structure 3b are arranged on the tailstock 3 or/and the handle 2, the force-bearing pull rod 1 can be flexibly converted at the preparation operation position, the extrusion operation position and the hidden-shrinkage containing position and can be maintained on a corresponding station according to actual requirements, on one hand, the advantage of convenient holding and control of a hand-held pneumatic glue gun is kept, on the other hand, the structure can better adapt to different use working conditions of the glue gun, and therefore, the use suitability is improved; furthermore, the hand-held pneumatic glue gun can be suitable for extruding soft paste bodies with different shapes such as hard shell packages, soft shell packages and the like by arranging the components such as the cylinder shell 9, the piston 10, the gun nozzle 12 and the like, and particularly, the shell cutting process of the traditional glue gun which needs to be carried out on the soft paste bodies in advance can be avoided by arranging the bag breaking component 13, so that the using objects and the range of the glue gun are effectively expanded, and the operation comfort is improved.
The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
