Description

Vibrating device pipe joint

The present invention provides a pipe joint, in particular a pipe joint of a vibration device.

At present, the pipe joint used for the vibration device, please refer to the first type of pipe joint shown in Figure 1 and Figure 2. One end of the pipe joint 1 is matched with the patent TW I767146 concrete vibration device 2 previously applied by the applicant. The concrete vibration device 2 is first connected to a hose 21, and the hose 21 is connected to a pipe joint 1. The pipe joint 1 is connected to a sleeve 31 of a power source 3. The sleeve 31 uses a pull rod 32 with a spring (not shown) for extension and contraction, so that the pull rod 32 is inserted and fixed in one end of the pipe joint 1. The pipe joint 1 includes an outer pipe 11 and a set of fixing components 12. The outer pipe 11 is made of a metal pipe and the inner diameter 10 of the outer pipe 11 that matches the hose 21 is selected. The outer pipe 11 is machined on a lathe to complete the shape. One end of the outer pipe 11 is matched with the sleeve 31 of the power source 3 to form a first set of pipes 111. The other end of the outer pipe 11 is assembled with the set of fixing components 12 and has an outer diameter smaller than that of the first set of pipes 111. Two sets of pipes 113, the first set of pipes 111 has a first clamping groove 112, the second set of pipes 113 has a second clamping groove 114, the sleeve assembly 12 includes an upper sleeve 121 arranged above the second set of pipes 113, a lower sleeve 122 opposite to the upper sleeve 121 and sleeved below the second set of pipes 113, and two fixing members 123 respectively fixed to both sides of the upper sleeve 121 and the lower sleeve 122. A first embedding groove 1211 and a second embedding groove 1221 are disposed inside the opposite ends of the upper sleeve 121 and the lower sleeve 122, and a first fixing body 1212 and a second fixing body 1222 are disposed inside the opposite ends of the upper sleeve 121 and the lower sleeve 122. The first embedding groove 1211 and the second embedding groove 1221 are connected to the upper and lower parts of the second clamping groove 114 of the second pipe assembly 113. 1212 and the inner periphery of the second fixed body 1222 are respectively provided with a plurality of first convex sections 1213 and a plurality of second convex sections 1223 at intervals. The first convex sections 1213 and the second convex sections 1223 are used to clamp the hose 21, and then the two fixing members 123 are used to fix the upper sleeve 121 and the lower sleeve 122 respectively, so that a spiral spring tube (not shown) can be inserted into the inner part of the outer tube 11 and the hose 21. However, the outer tube 11 is completely machined by lathe and needs to be matched with the sleeve assembly 12, which not only consumes machining labor and material costs, but also is more troublesome in assembly.

Furthermore, in order to improve the cost problem of the above-mentioned pipe joint 1, such as the need for machining and more consumable materials, and the troublesome assembly, the industry has designed a second pipe joint 4 that does not require a sleeve assembly to fix. Please refer to Figures 3 and 4. The pipe joint 4 includes an outer tube 41. The outer tube 41 is made of a metal tube. The inner diameter 40 of the outer tube 41 that meets the requirements of connecting a hose 42 is selected. The outer tube 41 is machined using a lathe. Then, at one end of the outer tube 41, a threaded portion 40 is formed. 411 has the same structure as the first set of pipes 111 of the first type of pipe joint 1. The other end 412 of the outer tube 41 is matched with the hose 42. A coil spring tube (not shown) is inserted into the inner part of the outer tube 41 and the hose 42. The outer surface of the hose 42 is matched with the inner part of the other end 412 of the outer tube 41 and is pressurized (as shown by the dotted arrow in Figure 4) to fix it, so that the other end 412 of the outer tube 41 is squeezed and fixed with the hose 42.

The pipe joint 4 described above is faster to assemble than the first pipe joint 1, but it has the same disadvantage that the outer tube 41 is completely machined by lathe, which results in cost issues such as labor and material consumption during the process, so it is necessary to improve it.

The main purpose of the present invention is to solve the problem that the existing pipe joint needs to use lathe turning to complete the outer tube shape, which results in costly turning and material consumption in the process, and to provide a pipe joint of a vibration device, which uses the connecting pipe to insert the straight tube matched with the outer tube, and makes one end of the straight tube pressed and fixed in the first clamping ring, thereby providing a method that can reduce costs and improve assembly efficiency.

To achieve the above-mentioned invention purpose, the technical means used in the present invention is to provide a pipe joint of a vibration device, the pipe joint includes an outer tube, the outer tube includes a straight tube, a tapered tube connected to one end of the straight tube, and a tapered tube connected to the tapered tube and opposite to the straight tube, the outer tube is formed by a tapered tube mold; and a connecting tube, the connecting tube has a through hole, the connecting tube includes a first convex ring for connecting the straight tube, a first clamping ring connected to one end of the first convex ring and for pressing and clamping one end of the straight tube, a second convex ring connected to the first clamping ring and opposite to the first convex ring, a second clamping ring connected to the second convex ring and opposite to the first clamping ring, and a third convex ring connected to the second clamping ring and opposite to the second convex ring.

Furthermore, the outer diameter of the first protrusion is larger than the outer diameter of the first retaining ring, the outer diameter of the second protrusion is larger than the outer diameter of the first protrusion, the outer diameter of the second retaining ring is smaller than the outer diameter of the first retaining ring, and the outer diameter of the third protrusion is equal to the outer diameter of the second protrusion.

Furthermore, when the diameter of one end of the straight tube is not large enough, the tube expansion is performed using the tube reduction mold.

Through the above disclosure of the present invention, compared with the existing ones, it has the following characteristics:

1. The straight tube of the outer tube of the present invention is nested with the first convex ring of the connecting tube, and the outer surface of the straight tube facing the first clamping ring is pressurized and clamped, so that the straight tube is firmly abutted against the second convex ring, and then the pulling rod of the sleeve is clamped and fixed in the second clamping ring of the connecting tube, thereby using the connecting tube to insert the straight tube matched with the outer tube, and one end of the straight tube is pressed and clamped in the first clamping ring.

2. The present invention facilitates easy engagement and fixing with the outer tube through the connecting tube during assembly, which not only simplifies the steps, but also greatly reduces costs and improves assembly efficiency.

The contraction tube 63 is connected to the inside of the straight tube 61. More specifically, the outer tube 6 is formed by a contraction tube mold 8.

Referring again to Figures 5 and 6, the connecting tube 7 has a through hole 71, and the connecting tube 7 includes a first protruding ring 72 for connecting the straight tube 61, a first clamping ring 73 connected to one end of the first protruding ring 72 and for pressing and clamping one end of the straight tube 61, a second protruding ring 74 connected to the first clamping ring 73 and opposite to the first protruding ring 72, a second clamping ring 75 connected to the second protruding ring 74 and opposite to the first clamping ring 73, and a third protruding ring 76 connected to the second clamping ring 75 and opposite to the second protruding ring 74.

As mentioned above, in this embodiment, the outer diameter of the first protruding ring 72 is larger than the outer diameter of the first snap ring 73, the outer diameter of the second protruding ring 74 is larger than the outer diameter of the first protruding ring 72, the outer diameter of the second snap ring 75 is smaller than the outer diameter of the first snap ring 73, and the outer diameter of the third protruding ring 76 is equal to the outer diameter of the second protruding ring 74.

Referring to Figures 7 and 8, the tube shrinking mold 8 includes a bottom mold 81, a punch mold 82, and a set of clamping molds 83, wherein the bottom mold 81 has a mold hole 811, and the hole shape of the mold hole 811 is formed by extrusion according to the shape of the outer tube 6. The end of the punch mold 82 forms a tapered rod portion 821 that matches the mold hole 811 of the bottom mold 81. The sleeve mold 83 includes a first internal space 831 and a second internal space 832 which are opposite to each other in the upper and lower parts, and a fixing assembly 833 which is locked outside the first internal space 831 above the sleeve mold 83, wherein the inner diameter of the first internal space 831 is for the tapered rod 821 of the punch mold 82 to be placed therein, and the second internal space 832 is for the one end 611 of the straight tube 61 to be placed therein, and the other end 612 of the straight tube 61 is aligned with the mold hole 811 of the bottom mold 81. When the tapered rod 821 of the punch mold 82 is placed in the first internal space 831 of the sleeve mold 83 and pressure is applied downward (as shown in FIG. 7), the other end 612 of the straight tube 61 is pressed downward. 612 is extruded from the die hole 811 to form the tapered tube 62 and the reduced tube 63 of the outer tube 6 (as shown in FIG. 8 ); in addition, if the diameter of one end 611 of the straight tube 61 meets and is provided for the first convex ring 72 of the connecting pipe 7 to be matched and embedded, it is not necessary to expand the diameter of one end 611 of the straight tube 61; referring to FIG. 9 again, if the diameter of one end 611 of the straight tube 61 is not large enough, the tapered rod 821 of the punch 82 is used to expand the inner diameter of one end 611 of the straight tube 61 downward, so that one end 611 of the straight tube 61 can be matched and embedded with the first convex ring 72 of the connecting pipe 7.
