Description

Anchor device for guiding buckle and its component assembly

The present invention relates to a device for connecting two devices each having a fluid path; in particular, it discloses an innovative structural form of a connecting device with a guide buckle and its component assembly.

A pipe joint is known, comprising a first pipe joint, a second pipe joint, and a C-shaped buckle ring, wherein two pipes are connected to the first pipe joint and the second pipe joint respectively. The first pipe joint forms an insertion portion, and the radial outer periphery of the insertion portion is recessed to form an annular groove surrounding the insertion portion. The second pipe joint forms two embedding grooves respectively connecting the outside and the inside of the second pipe joint, and the embedding grooves are opposite to each other along the radial direction of the second pipe joint. The insertion portion is axially inserted into the second pipe joint, and the embedding grooves are respectively aligned with the annular grooves. The grooves are opposite and connected along the radial direction of the second pipe joint. The C-shaped buckle is buckled into each of the embedded grooves and the annular groove from the outside of the second pipe joint. The C-shaped buckle clamps the insertion portion by its elasticity. The portions of the insertion portion located on both sides of the annular groove along the axial direction form relative restrictions with the C-shaped buckle. The portions of the second pipe joint located on both sides of the embedded groove along the axial direction form relative restrictions with the C-shaped buckle. Accordingly, the first pipe joint and the second pipe joint are axially connected via the C-shaped buckle.

The conventional pipe connector has been found to have the following problems and drawbacks in actual application experience: the C-shaped buckle elastically expands outwardly along its radial direction to clamp the insert portion, and the pipe connector lacks a structure to block or restrict the radial outer portion of the buckle. When the first pipe connector and the second pipe connector form relative misalignment along their axial direction, the elastic restoring force of the C-shaped buckle easily causes the C-shaped buckle to slide out of the annular groove, thereby releasing the axial connection between the first pipe connector and the second pipe connector formed by the buckle.

The main purpose of this invention is to provide a guide buckle joint device and its component assembly. The technical problem it aims to solve is to explore and innovate a new type of joint device with a more ideal and practical goal.

Based on the above objectives, the technical features of the present invention to solve the problem are mainly that the joint device of the guide buckle includes:

a first connector for connecting to a first device, the first connector passing through a channel for communicating with the first device to provide a path for fluid to pass through, the first connector forming a plug portion, and the channel extending through the plug portion;

A component assembly includes a second connector and a plug buckle, wherein the second connector is used to connect to a second device, the second connector cooperates with the plug portion to form a space, the space extends to one axial end of the second connector, the plug portion is inserted into the space, so that the first device is connected to the second device through the channel, and a virtual line segment is defined through the center of the second connector in the radial direction, and the line segment is aligned with the first device. The two joints intersect axially, and the line segment extends through the radial periphery of the second joint. The second joint forms a first through-slot and two second through-slots. The first through-slot connects the space and the radial periphery of the second joint along the direction of the line segment. Each of the second through-slots connects the space and the radial periphery of the second joint along a direction parallel to the line segment. The second joint forms two planes, and the space passes between the planes.

The buckle is primarily composed of two prongs and a connecting portion. The prongs are laterally opposed to each other. The connecting portion connects the prongs at one end in the same direction. The prongs are respectively inserted into the first through-slot and the second through-slot, thereby clamping the connecting portion to axially position the first connector and the second connector. The prongs are respectively located between the planes, and the planes respectively form a stop for the prongs.

Each of the planes extends to form a slot wall of the first through-slot, and each of the planes extends to form a slot wall of each of the second through-slots on a side away from the line segment. The second joint forms two vertical walls, each of which forms a slot wall of each of the second through-slots on a side adjacent to the line segment. Each of the vertical walls has a first wall surface, a second wall surface, and an abutting surface. Each of the first walls extends to the space, and each of the second walls extends to the radial periphery of the second joint. Each of the abutting surfaces connects each of the first walls and each of the second walls. The distance between each of the second walls and the line segment is smaller than the distance between each of the first walls and the line segment.

Each of the pins passes through two slots, each of the slots extends to the side of the pin facing the line segment, and each of the slots extends away from the line segment. Each of the pins forms a spring portion, each of the spring portions is located at an end of the pin away from the connecting portion, and each of the spring portions is adjacent to each of the slots. Each of the spring portions protrudes relative to each other to form a convex portion, and each of the convex portions abuts against each of the abutting surfaces, thereby positioning the buckle.

The main effect and advantage of the present invention is that each plane forms a lateral stop restriction on the outer side of each pin, so that each pin will not arbitrarily release the clamping effect on the plug part, and the axial connection relationship between the first connector and the second connector can be ensured.

Please refer to the drawings, which are embodiments of the present invention. However, these embodiments are for illustrative purposes only and are not limited to these structures in patent applications.

As shown in Figures 1 to 6, embodiment 1 of the present invention includes a first connector 10 and a component assembly 02, wherein the first connector 10 is used to connect to a first device 92. The first connector 10 passes through a channel 12 for connecting to the first device 92 to provide a path 93 for fluid to pass through. The first connector 10 forms a plug portion 14, and the channel 12 extends through the plug portion 14.

The component assembly 02 includes a second connector 20 and a buckle 30, wherein the second connector 20 is used to connect to a second device 94. The second connector 20 cooperates with the plug-in portion 14 to form a space 21, which extends to one axial end of the second connector 20. The plug-in portion 14 is inserted into the space 21, so that the first device 92 is connected to the second device 94 through the channel 12. Figure 5 shows that the first device 92 and the second device 94 are respectively tubular, which is only an example of a usage state of the first embodiment. The first device 92 and the second device 94 can also be sprinkler guns or other devices with a path 93 for fluid to pass through. Figure 5 cannot be used to limit the use of the first embodiment.

A virtual line segment 96 is defined through the radial center of the second joint 20. The line segment 96 intersects the axial direction of the second joint 20 and extends through the radial periphery of the second joint. In this example, the line segment 96 is selected to be orthogonal to the axial direction of the second joint 20. The second joint 20 forms a first through-slot 22 and two second through-slots 23. The first through-slot 22 connects the space 21 and the radial periphery of the second joint 20 along the direction of the line segment 96. Each of the second through-slots 23 connects the space 21 and the radial periphery of the second joint 20 along a direction parallel to the line segment 96. The second joint 20 forms two planes 24. Each of the planes 24 is selected to be parallel to the line segment 96. The space 21 passes between the planes 24.

The buckle 30 is primarily comprised of a connecting portion 31 and two prongs 32. The prongs 32 are laterally opposed to one another. The connecting portion 31 connects the prongs 32 at one end in the same direction. The prongs 32 are inserted into the first through-slot 22 and the second through-slot 23, respectively, thereby engaging the connecting portion 14 and axially positioning the first connector 10 and the second connector 20. The prongs 32 are positioned between the flat surfaces 24, which act as a stop for the prongs 32, preventing them from expanding in opposite directions.

Each of the planes 24 extends to form the groove wall of the first through-groove 22, and each of the planes 24 extends to form the groove wall of each of the second through-groove 23 away from the direction of the line segment 96. The second joint 20 forms two vertical walls 25 to form the groove wall of each of the second through-groove 23 adjacent to the direction of the line segment 96. Each of the vertical walls 25 has a first wall surface 252, a second wall surface 254, and a support surface 256. Surface 256, wherein each first wall 252 extends to the space 21, each second wall 254 extends to the radial periphery of the second joint 20, each abutting surface 256 connects each first wall 252 and each second wall 254, and the distance between each second wall 254 and the line segment 96 is smaller than the distance between each first wall 252 and the line segment 96.

Each of the pins 32 passes through two slots 33, and each of the slots 33 extends to the side of each pin 32 facing the line segment 96, and each of the slots 33 extends away from the line segment 96. Each of the pins 32 forms a spring portion 34, and each of the spring portions 34 is located at one end of each pin 32 away from the connecting portion 31, and each of the spring portions 34 is adjacent to each of the slots 33. The formation of each slot 33 can respectively improve the elasticity of the movement of each pin 32. Each elastic portion 34 respectively extends relative to each other to form a protrusion 35. Each protrusion 35 respectively abuts against each abutment surface 256. Accordingly, each abutment surface 256 respectively forms a stop for each protrusion 35, so that each pin 32 cannot arbitrarily move in the direction of exiting each second through slot 23, thereby positioning the buckle 30.

When the first connector 10 is connected to the second connector 20, the plug portion 14 enters the space 21 along its axial direction. Then, the buckle 30 is inserted into the second connector 20 from the radially outward direction of the second connector 20. The pins 32 pass through the first through-slots 22 and then enter the second through-slots 23 respectively until the connecting portion 31 enters the first through-slots 22, completing the arrangement of the buckle 30. The pins 32 clamp the plug portion 14 relative to each other, preventing the plug portion 14 from exiting the space 21, thus completing the connection between the first connector 10 and the second connector 20. Accordingly, a method for coupling the first device 92 and the second device 94 is implemented.

During the process of inserting each pin 32 into each second through slot 23, each flat surface 24 forms a lateral stop for each pin 32 on the outer side of each pin 32. When each protrusion 35 contacts each vertical wall 25, each vertical wall 25 forces each elastic portion 34 to elastically actuate, so that each protrusion 35 can pass over each first wall 252 and face each second wall 254 and the abutting surface 256, forming a retreated second wall relative to each first wall 252. 254, so that each elastic portion 34 moves in the direction of elastic recovery, and each protrusion 35 abuts against each abutting surface 256. Each abutting surface 256 forms a blocking restriction on each protrusion 35 in the direction adjacent to the first through-slot 22, and each pin 32 cannot arbitrarily move in the direction of exiting each second through-slot 23, thereby positioning the buckle 30. The buckle 30 restricts the plug-in portion 14 from exiting the space 21, and the first connector 10 and the second connector 20 complete the axial connection.

When the buckle 30 enters the second connector 20, the flat surfaces 24 form lateral stops on the outer sides of the pins 32. The pins 32 will not arbitrarily release the clamping action on the plug portion 14, thereby ensuring the axial connection between the first connector 10 and the second connector 20.

The formation of each second wall surface 254 and its relative spatial configuration with each abutment surface 256 ensures that when each protrusion 35 abuts each abutment surface 256, each protrusion 35 can be completely accommodated between each vertical wall 25 and the radial periphery of the second joint 20. Each protrusion 35 can be selected not to protrude radially outward from the second joint 20. When external objects or user operations touch the second joint 20, they will not accidentally contact and push each protrusion 35, thereby preventing the relative abutment state between each protrusion 35 and each abutment surface 256 from being accidentally released.

Furthermore, the connecting portion 31 can be received in the first through slot 22 without protruding radially outward from the second joint 20 .

An annular groove 16 is selectively formed along the radial direction of the outer periphery of the plug portion 14. The first through-groove 22 and each of the second through-grooves 23 are respectively connected to the annular groove 16. Each of the pins 32 passes through the annular groove 16. Therefore, each of the pins 32 forms a limit on the plug portion 14 along the axial direction of the plug portion 14, thereby restricting the plug portion 14 from exiting the space 21.

The connecting portion 31 is curved toward the direction between the pins 32 . Specifically, the connecting portion 31 is a curved strip structure.

Each of the protrusions 35 is selectively formed with a curved surface 36 on a side away from each of the slots 33 .

As shown in FIG7 , the main difference between the second embodiment and the first embodiment is that the shortest distance between the protrusions 35 is less than the outer diameter of the portion of the connecting portion 14 located in the annular groove 16 . Accordingly, if the buckle 30 moves toward the direction of exiting the first through-slot 22 due to user misoperation or accident, the connecting portion 14 will form a blocking effect on the protrusions 35 moving toward the first through-slot 22 , preventing the buckle 30 from being easily released from the connecting portion 14 .
