Description

Technical Field

[0001] This invention relates to the field of snap-lock disassembly technology, and more particularly to a snap-lock disassembly wrench. Background Technology

[0002] Currently, vehicles use cross-shaped double-sleeve clips to secure interior trim components. During vehicle inspection and repair, the clips must be removed before the trim components can be taken out. Disassembly is usually done using tools such as screwdrivers, wrenches, or flathead pliers. This process often results in damage to the trim components or breakage of the clips and claws, leading to increased costs.

[0003] Existing clip removal tools generally have a connecting part for detachable connection with the clip. When the clip needs to be removed, the connecting part needs to be put on the clip, and then force is applied to pull the clip out. This allows for simple and convenient clip removal with high efficiency and simple operation. However, when the clip is pulled out by the operator directly using the removal tool, the connecting part and the clip often come into contact with each other and the excessive force applied during the pull-out process can damage the clip or even cause the interior trim to break.

[0004] Therefore, it is necessary to provide a new disassembly tool to solve the above-mentioned technical problems. Summary of the Invention

[0005] The main objective of this invention is to provide a buckle removal wrench, which aims to solve the problems of inconvenient operation and easy damage to buckles and interior parts caused by buckle removal wrenches.

[0006] To achieve the above objectives, the present invention proposes a snap-lock release wrench for disassembling snap-locks. The snap-lock has two opposing notches at its top. The snap-lock release wrench includes a mounting sleeve, a jaw assembly, and a locking assembly. The mounting sleeve has a mounting cavity with an opening at one end. The jaw assembly includes a mounting base and two jaws opposing each other on both sides of the mounting base. The mounting base is slidably disposed at the opening. The two jaws are rotatably connected to the mounting base. The mounting base can move between a first position and a second position. When the mounting base is in the first position, the mounting base extends... When the mounting base moves to the second position, it retracts into the opening, and the two grippers clamp in a clamping state, respectively engaging the two notches to secure the buckle. The locking assembly includes a locking rod mechanism, a first pull rod, and a reset member disposed within the mounting cavity. The locking rod mechanism is rotatably connected to the inner wall of the mounting cavity. The first pull rod is connected to the mounting base. The reset member is disposed around the first pull rod and abuts against the mounting base and the inner wall of the mounting cavity. The locking rod...

[0007] When the mechanism and the first pull rod are locked together, the mounting base is in the second position. When the locking rod 5 mechanism disengages from the first pull rod, the reset member pushes the mounting base to move away from the locking rod mechanism to the first position.

[0008] Optionally, the gripper assembly further includes a first elastic element, the number of which is the same as the number of grippers and they are arranged in a one-to-one correspondence, and the first elastic element abuts against the mounting base and the corresponding gripper.

[0009] Optionally, the gripper includes a connecting portion and a clamping portion connected to each other. The connection between the connecting portion and the clamping portion is rotatably connected to the mounting base. The clamping portion protrudes from the opening to form a hook structure. The connecting portion is inclined in a direction away from the hook structure and in a direction away from the diameter of the mounting base.

[0010] Optionally, the mounting base includes a base body, a positioning member, and a second elastic member. The base body has a sliding cavity with openings at both ends. The sliding cavity is arranged axially. The positioning member is slidably disposed in the sliding cavity, and one end of the positioning member is connected to the first pull rod. The other end of the positioning member protrudes from the opening to position the buckle. The second elastic member is sleeved on the first pull rod and abuts against the positioning member and the inner wall of the sliding cavity.

[0011] Optionally, the seat body is provided with a limiting groove, the limiting groove having a first stop surface and a second stop surface arranged axially, the fastener passing through the mounting sleeve and extending into the limiting groove, the mounting seat being in a first position when the fastener abuts against the first stop surface, and the mounting seat being in a second position when the fastener abuts against the second stop surface.

[0012] Optionally, the mounting cavity includes a connecting section and a mounting section that communicate with each other. The mounting section communicates with the opening, and a stepped surface is formed at the connection between the connecting section and the mounting section. The reset member is pressed against the stepped surface and the seat.

[0013] Optionally, the locking rod mechanism includes a second pull rod and a pressing spring. The second pull rod is rotatably connected to the inner wall of the mounting cavity. One end of the second pull rod is used for a snap-fit ​​connection with the first pull rod. The other end of the second pull rod is connected to the inner wall of the connecting section, and the pressing spring is pressed against the release button and the inner wall of the connecting section.

[0014] Optionally, the second pull rod includes a rod body and a release button. The rod body is rotatably connected to the inner wall of the connecting section and is used for snap-fit ​​connection with the first pull rod. The mounting sleeve is provided with a through groove, which communicates with the connecting section. The release button is connected to the end of the rod body away from the first pull rod and extends out of the through groove to form a pressing part.

[0015] Optionally, the first pull rod includes a hook structure and a sliding section connected together. The hook structure is used to engage with the second pull rod. The sliding section extends into the sliding cavity and connects with the positioning member. The connection between the sliding section and the hook structure is provided with a stepped surface. The stepped surface abuts against the mounting base to stop the first pull rod.

[0016] Optionally, the latch removal wrench further includes an operating handle for gripping.

[0017] In this invention, when disassembling the buckle, the operator needs to align the mounting base with the buckle so that the two grippers are aligned with the two notches on the top of the buckle. At this time, the mounting base is in the first position, the locking rod mechanism is disengaged from the first pull rod, and the two grippers are in an open state. The operator then presses the mounting sleeve, causing the mounting sleeve to slide down, the locking rod mechanism and the first pull rod to engage, and the reset member abutting between the mounting base and the inner wall of the mounting cavity is in a compressed state. Simultaneously, the mounting base moves to the second position, and the two grippers clamp together to fix the buckle. The mounting sleeve is pulled upward and rotated simultaneously to disengage the buckle. Finally, the locking rod mechanism is pressed, causing it to rotate and disengage from the first pull rod, thereby the reset member pushes the mounting base away from the locking rod mechanism to move back to the first position. This invention allows the buckle to be removed by pressing the mounting sleeve to clamp it, then rotating the mounting sleeve and pulling upward. The operation is simple and convenient, effectively avoiding damage to the buckle due to excessive force during disassembly, and also protecting the interior trim panel. Attached Figure Description

[0030] This invention proposes a buckle removal wrench, which aims to solve the problems of inconvenient operation and easy damage to buckles and interior parts caused by buckle removal wrenches.

[0031] like Figures 1 to 3As shown, the latch removal wrench 100 includes a mounting sleeve 10, a gripper assembly 20, and a locking assembly 30. The mounting sleeve 10 has a mounting cavity 11 with an opening 113 at one end. The gripper assembly 20 includes a mounting base 21 and two grippers 22 disposed opposite to each other on both sides of the mounting base 21. The mounting base 21 is slidably disposed at the opening 113, and the two grippers 22 are rotatably connected to the mounting base 21. The mounting base 21 can move between a first position and a second position. When the mounting base 21 is in the first position, the mounting base 21 extends out of the opening 113, and the two grippers 22 are in an open state. When the mounting base 21 moves to the second position, the mounting base 21 retracts into the opening 113, and the two grippers 22 clamp. In the tight state, the two grippers 22 respectively engage with the two notches to secure the buckle; the locking assembly 30 includes a locking rod mechanism 31, a first pull rod 32, and a reset member 33 disposed in the mounting cavity 11. The locking rod mechanism 31 is rotatably connected to the inner wall of the mounting cavity 11. The first pull rod 32 is connected to the mounting base 21. The reset member 33 is disposed on the periphery of the first pull rod 32 and abuts against the mounting base 21 and the inner wall of the mounting cavity 11. When the locking rod mechanism 31 and the first pull rod 32 are locked together, the mounting base 21 is in the second position. When the locking rod mechanism 31 disengages from the first pull rod 32, the reset member 33 pushes the mounting base 21 to move away from the locking rod mechanism 31 to the first position. Specifically, the buckle is engaged in the mounting hole on the interior trim. When removing the buckle, the operator needs to align the mounting base 21 with the buckle so that the two grippers 22 are aligned with the two notches on the top of the buckle. At this time, the mounting base 21 is in the first position, the locking rod mechanism 31 is disengaged from the first pull rod 32, and the two grippers 22 are in the open state. The operator then presses the mounting sleeve 10, the mounting sleeve 10 slides down, the locking rod mechanism 31 and the first pull rod 32 engage with each other, and the reset member 33, which abuts against the inner wall of the mounting base 21 and the mounting cavity 11, is in the compressed state. At the same time, the mounting base 21 slides towards the locking rod mechanism 31 to move to the second position, and the two grippers 22 are in the open state. Under the limiting action of the inner wall of the mounting cavity 11, the claws 22 change from an open state to a clamping state, so that the two claws 22 cooperate to fix the buckle; pull the mounting sleeve 10 upward and rotate the mounting sleeve 10 at the same time. The mounting sleeve 10 drives the mounting base 21 to rotate, and the mounting sleeve 10 pulls the two claws 22 through the mounting base 21. At the same time, the two claws 22 drive the buckle to rotate along the inner wall of the mounting hole and slide upward, so that the buckle slowly disengages from the mounting hole; finally, press the locking rod mechanism 31. The locking rod mechanism 31 rotates to disengage from the first pull rod 32, so that the reset member 33 pushes the mounting base 21 to move away from the locking rod mechanism 31 to the first position. The present invention can remove the buckle by pressing the mounting sleeve 10 to clamp the buckle, and then rotating the mounting sleeve 10 and pulling it upward. The operation is simple and convenient. By rotating the buckle, the force on the buckle is distributed, which effectively avoids the problem of the buckle being damaged due to excessive force during disassembly, and also protects the interior panel.

[0032] Furthermore, the gripper assembly 20 also includes a first elastic member 23, the number of which is the same as the number of grippers 22 and they are arranged in a one-to-one correspondence. The first elastic member 23 abuts against the mounting base 21 and the corresponding gripper 22. The gripper 22 includes a connecting part 221 and a clamping part 222 that are connected to each other. The connection between the connecting part 221 and the clamping part 222 is rotatably connected to the mounting base 21. The clamping part 222 protrudes from the opening 113 to form a hook structure 223. The connecting part 221 is inclined in the direction away from the hook structure 223 towards the direction in which the diameter of the mounting base 21 increases. Each first elastic element 23 abuts against the clamping portion 222 of the corresponding gripper 22 and the mounting base 21. The connection between the clamping portion 222 and the hook structure 223 is an arc-shaped curved surface transition. The connecting portion 221 is inclined in the direction away from the hook structure 223 towards the direction of increasing diameter of the mounting base 21, thereby forming a gap space between the connecting portion 221 and the mounting base 21 for the connecting portion 221 to pass through. When the mounting base 21 is in the first position, the first elastic element 23 pushes the clamping portion 222 of the corresponding gripper 22 away from the mounting base 21. When the 1-axis rotation is performed, the connecting part 221 rotates towards the mounting base 21, at which point the two grippers 22 are in an open state. After the two hook structures 223 are respectively inserted into the corresponding notches on the buckle, the mounting sleeve 10 is pressed. The gripping part 222 of the gripper 22 is pressed by the inner wall of the opening 113 of the mounting sleeve 10 and rotates towards the mounting base 21. At the same time, the first elastic element 23 is compressed, and the connecting part 221 rotates away from the mounting base 21, so that the two clamping structures cooperate to fix the buckle. When the installation sleeve 10 is pressed, the inner wall of the opening 113 of the installation sleeve 10 is pressed against the arc-shaped surface of the two jaws 22, which avoids hard collision between the installation sleeve 10 and the jaws 22 and increases the service life of the buckle removal wrench 100. The jaw assembly 20 first opens so that the clamping mechanism can be engaged with the corresponding notch, and then clamps to fix the buckle. This effectively avoids damage to the buckle when the buckle removal wrench 100 fixes the buckle. Moreover, the clamping mechanism and the notch of the buckle are tightly matched, which can prevent the buckle from coming out of the clamping assembly during the disassembly process, thus preventing damage to the interior parts and the buckle.

[0033] In one embodiment, the mounting base 21 includes a base body 211, a positioning member 212, and a second elastic member 213. The base body 211 has a sliding cavity 211a with one end open 113. The sliding cavity 211a is arranged axially. The positioning member 212 is slidably disposed in the sliding cavity 211a. One end of the positioning member 212 is connected to the first pull rod 32, and the other end of the positioning member 212 protrudes from the opening 113 for positioning and locking. The second elastic member 213 is sleeved on the first pull rod 32 and abuts against the inner wall of the positioning member 212 and the sliding cavity 211a. The base 211 has mounting grooves on both sides for the gripper 22 to engage. One side of the gripper 22 engages in the mounting groove, and the other side of the gripper 22 is slidably connected to the inner wall of the mounting cavity 11. The gripper 22 is rotatably positioned within the mounting groove. The base 211 also has a sliding cavity 211a with one end open to 113. The end of the base 211 away from the opening 113 has a channel communicating with the sliding cavity 211a. The channel allows the first pull rod 32 to pass through and engage with the positioning member 212. The positioning member 212 slides in contact with the inner wall of the sliding cavity 211a, and the end of the positioning member 212 away from the first pull rod 32 protrudes from the opening 113 of the sliding cavity 211a for positioning and buckling. The positioning member 212 is provided with a positioning protrusion, and the top of the buckle is provided with a groove that matches the positioning protrusion. The second elastic member 213 is sleeved on the first pull rod 32, and the second elastic member 213 abuts against the positioning member 212 and the inner wall of the sliding cavity 211a. When disassembling the buckle, first insert the positioning protrusion into the groove. At this time, the two clamping mechanisms will engage with the corresponding notches. Then press the installation sleeve 10. The buckle applies a reaction force to the positioning member 212, causing the positioning member 212 to slide closer to the first pull rod 32. The second elastic member 213 is compressed by the positioning member 212. The positioning member 212 pushes the first pull rod 32 to slide closer to the locking rod mechanism 31. At the same time, the installation sleeve 10 drives the locking rod mechanism 31 to slide towards the first pull rod 32, thereby locking the locking rod mechanism 31 and the first pull rod 32 into interlocking. The mounting base 21 slides to the second position, and the two clamping structures cooperate to clamp the buckle. The operator rotates and pulls the buckle removal wrench 100 upward to dislodge the buckle from the mounting hole on the interior panel. After pressing the locking mechanism, the reset member 33 pushes the mounting base 21 to slide to the first position, and the two clamps open to release the buckle. The buckle disengages from the positioning member 212, and the positioning member 212 loses the reaction force applied by the buckle. The second elastic member 213 pushes the positioning member 212 to slide towards the opening 113 of the sliding cavity 211a until the positioning member 212 is reset. By inserting the positioning protrusion into the groove on the buckle, the two clamping structures can be accurately aligned with the notch on the top of the buckle to clamp the buckle. The operation is simple and can achieve quick positioning, reducing the time spent aligning the buckle removal wrench 100 with the positioning buckle during disassembly and improving the disassembly efficiency of the buckle removal wrench 100.

[0034] Based on the above embodiments, the seat 211 is provided with a limiting groove 211b. The limiting groove 211b has a first stop surface and a second stop surface arranged axially. The fastener passes through the mounting sleeve 10 and extends into the limiting groove 211b. When the fastener abuts against the first stop surface, the mounting seat 21 is in a first position. When the fastener abuts against the second stop surface, the mounting seat 21 is in a second position. The seat 211 is slidably connected to the inner wall of the mounting cavity 11. The fastener passes through the mounting sleeve 10 and extends into the limiting groove 211b on the seat 211. The limiting groove 211b has a first stop surface and a second stop surface arranged axially. When the mounting seat 21 is in the first position, the fastener abuts against the first stop surface. When the mounting seat 21 slides from the first position to the second position, the fastener moves along the limiting groove 211b away from the first stop surface until the fastener abuts against the second stop surface. The fastener is limited by the first stop surface and the second stop surface, so that the mounting seat 21 can slide between the first position and the second position in the mounting cavity 11. This ensures that the mounting seat 21 can be accurately positioned in the first position and the second position, and prevents the mounting seat 21 from shifting in the mounting cavity 11.

[0035] The mounting cavity 11 includes a connecting section 111 and a mounting section 112 that are interconnected. The mounting section 112 is connected to the opening 113. A stepped surface is formed at the connection between the connecting section 111 and the mounting section 112. The reset member 33 is pressed between the stepped surface and the seat 211. The reset member 33 is sleeved on the first pull rod 32. One end of the reset member 33 abuts against the stepped surface, and the other end abuts against the seat 211. After the two clamping structures are inserted into the corresponding notches, the mounting sleeve 10 is pressed, causing the mounting seat 21 to slide to the second position. The seat 211 pushes the reset member 33 towards the step surface, compressing the reset member 33. At the same time, the seat 211 pushes the first pull rod 32 away from the clamping assembly, causing the first pull rod 32 to engage with the locking rod assembly to lock the mounting seat 21. At this time, the two clamping structures cooperate to clamp the buckle. Pull and rotate the buckle removal wrench 100 to remove the buckle. Then press the locking rod mechanism 31. The end of the locking rod mechanism 31 that is engaged with the first pull rod 32 rotates away from the first pull rod 32, causing the locking rod mechanism 31 and the first pull rod 32 to disengage. The mounting base 21 is released from the locked state. One end of the reset member 33 abuts against the stepped surface, and the other end of the reset member 33 pushes the mounting base 21 to slide from the second position to the first position. The mounting base 21 drives the clamp 22 to slide along the inner wall of the mounting cavity 11, so that the two clamping structures open and release the buckle. The reset member 33 can be a spring or other components with a reset function. The reset member 33 can push the mounting base 21 back from the second position to the first position, so that the clamping assembly returns from the clamped state to the open state, thereby saving the waiting time between the two disassembly operations and further improving the disassembly efficiency of the buckle removal wrench 100.

[0036] In one embodiment, the locking rod mechanism 31 includes a second pull rod 311 and a pressing spring 312. The second pull rod 311 is rotatably connected to the inner wall of the mounting cavity 11. One end of the second pull rod 311 is used to snap-fit ​​with the first pull rod 32. The other end of the second pull rod 311 is connected to the inner wall of the connecting section 111 with the pressing spring 312, which abuts against the second pull rod 311 and the inner wall of the connecting section 111. When the mounting base 21 is in the first position, the two grippers 22 are open, the second pull rod 311 and the first pull rod 32 are disengaged, and the pressing spring 312 is pressed between the second pull rod 311 and the inner wall of the connecting section 111. After aligning the positioning member 212 with the buckle, the mounting sleeve 10 is pressed. The mounting sleeve 10 drives the second pull rod 311 to move closer to the first pull rod 32. When the second pull rod 311 and the first pull rod 32 are engaged, the end of the second pull rod 311 away from the engagement point presses against the pressing spring 312. When the buckle is disengaged from the interior trim, the second pull rod 311 is pressed and then released. The pressing spring 312 pushes the second pull rod 311 to rotate and disengage from the first pull rod 32. Thus, the reset member 33 pushes the mounting base 21 to slide to the first position, and the two grippers 22 open to release the buckle. The operator can reset the buckle removal wrench 100 by pressing the second pull rod 311. The operation is simple, convenient and quick, improving the buckle removal efficiency.

[0037] Furthermore, the second pull rod 311 includes a rod body 311a and a release button 311b. The rod body 311a is rotatably connected to the inner wall of the connecting section 111 and is used for snap-fit ​​connection with the first pull rod 32. The mounting sleeve 10 is provided with a through groove 12, which communicates with the connecting section 111. The release button 311b is connected to the end of the rod body 311a away from the first pull rod 32 and extends out of the through groove 12 to form a pressing part. The rod body 311a is rotatably connected to the inner wall of the connecting section 111, and one end of the rod body 311a is connected to the release button 311b, while the other end of the rod body 311a is used for snap-fit ​​connection with the first pull rod 32. When the installation sleeve 10 is pressed, the installation sleeve 10 drives the second pull rod 311 to move closer to the first pull rod 32. The mounting seat 21 slides to the second position. The two ends of the reset member 33 are pressed against the stepped surface and the mounting seat 21. The fastener slides along the limiting groove 211b on the mounting seat 21 to abut against the second stop surface. The positioning member 212 abuts against the buckle. The positioning member 212 pushes the first pull rod 32 to slide away from the buckle. The first pull rod 32 and the second pull rod 311 are engaged with each other. At the same time, the two claws 22 clamp the buckle. After the buckle disengages from the mounting hole on the interior trim, the pressing part of the release button 311b is pressed. The release button 311b releases the buckle. b drives the rod 311a to rotate downwards, while the end of the rod 311a away from the release button 311b rotates upwards, thereby disengaging the rod 311a from the first pull rod 32. One end of the reset member 33 pushes the first pull rod 32 to move away from the second pull rod 311, and the other end of the reset member 33 pushes the mounting sleeve 10 to move away from the buckle through the stepped surface. The mounting base 21 slides to the first position, and the two grippers 22 open to release the buckle. The operation is simple and avoids the problem of increased cost caused by damage to the buckle by the grippers 22. In addition, the pressing part of the release button 311b is exposed in the through groove 12 so that the operator can press it.

[0038] In a preferred embodiment, the first pull rod 32 includes a hook structure 321 and a sliding section 322 connected together. The hook structure 321 is used to engage with the second pull rod 311. The sliding section 322 extends into the sliding cavity 211a and is connected to the positioning member 212. A stepped surface 323 is provided at the connection between the sliding section 322 and the hook structure 321. The stepped surface 323 abuts against the mounting base 21 to stop the first pull rod 32. The hook structure 321 is provided with a locking block and a locking groove for the locking block to engage. The locking groove matches the shape of the buckle. The second pull rod 311 also has a hook structure 321 at the end near the first pull rod 32. When the first pull rod 32 and the second pull rod 311 are engaged, the locking block of the first pull rod 32 engages in the locking groove of the second pull rod 311. The inner wall of the locking groove of the second pull rod 311 limits and stops the locking block of the first pull rod 32. Similarly, the locking block of the second pull rod 311 engages in the locking groove of the first pull rod 32. The inner wall of the locking groove of the first pull rod 32 limits and stops the locking block of the second pull rod 311. After pressing to release the locking block, the locking block of the second pull rod 311 rotates away from the second pull rod 311, and the two locking blocks disengage. The corresponding locking slots allow the first pull rod 32 and the second pull rod 311 to disengage from each other. When the first pull rod 32 and the second pull rod 311 disengage, the mounting base 21 is in the first position. At this time, the stepped surface 323 of the first pull rod 32 abuts against the mounting base 21, and a gasket is sleeved on the sliding section 322 of the first pull rod 32. The gasket is placed between the stepped surface 323 and the mounting base 21. When the mounting base 21 slides from the second position to the first position, the stepped surface 323 abuts against the mounting base 21 to stop the first pull rod 32. The gasket placed between the stepped surface 323 and the mounting base 21 can effectively prevent the stepped surface 323 and the mounting base 21 from wearing against each other, thereby increasing the service life of the buckle removal wrench 100.

[0039] In addition, the clip removal wrench 100 also includes an operating handle 40 for gripping. The operating handle 40 is connected to the end of the mounting sleeve 10 away from the opening 113. The operating handle 40 has an irregular curved surface that matches the contour of the hand to facilitate gripping by the operator. The operator presses and rotates the mounting sleeve 10 by operating the handle 40 to disengage the clip from the interior trim. The operation is simple and avoids collision between the clip removal wrench 100 and the clip or interior trim.

[0040] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
