Description

Technical Field

[0001] This invention relates to the field of locking device technology, and in particular to a locking detection mechanism. Background Technology

[0002] In the production and processing of various workpieces, workpieces with locking structures need to have their locking performance tested using a special testing fixture. Before testing, the workpiece's locking mechanism must be precisely locked onto the testing fixture, and after testing, the workpiece must be quickly unlocked and removed. Therefore, the ease of locking and unlocking of the locking mechanism directly affects the workpiece testing efficiency.

[0003] Currently, existing technologies for detecting and locking workpiece latches mostly employ a single sliding pin structure or a screw-type clamping structure to fix the latch. The sliding pin structure relies on an elastic element to drive the pin to lock, and while unlocking is relatively simple, it cannot maintain the unlocked state for extended periods. The screw-type clamping structure offers better locking stability, but requires turning a handle to lock and unlock, making the process cumbersome.

[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a detection locking mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A detection locking mechanism includes a base, a stop, a first elastic element, a rotating locking element, a sliding element, and a second elastic element. One side of the base has a recessed slot. The sliding element is slidably connected to the base and movably positioned on one side of the slot. A locking pin is provided at the end of the sliding element near the slot, and a handle is provided at the end of the sliding element away from the slot. The handle is located outside one end face of the base. The sliding element is elastically connected to the base via the second elastic element, which applies a spring force towards the slot to the sliding element. A gap is formed between the end face of the sliding element away from the handle and the locking pin. The locking step is formed, and the stop block is installed on the other side of the top surface of the base. One end of the rotating locking member is rotatably connected to the top surface of the base, and the other end of the rotating locking member is provided with an abutment block. The two ends of the first elastic member are elastically connected to the abutment block and the stop block respectively. The middle part of the rotating locking member is provided with a locking protrusion for abutting against the locking step. When the locking protrusion abuts against the locking step, the locking pin is located on one side of the slot, and the handle is separated from one end face of the base. When the handle abuts against one end face of the base, the locking pin extends laterally into the slot, and the locking protrusion separates from the locking step.

[0007] Furthermore, a sliding groove communicating with the slot is provided on one side of the top surface of the base. The sliding groove is located on the side of the slot, and the sliding component is moved within the sliding groove.

[0008] Furthermore, the sliding component includes a retaining ring and a guide rod coaxially connected, a locking pin is connected to the side of the retaining ring away from the guide rod, a guide sleeve is embedded in the sliding groove, the guide rod slides through the guide sleeve, a handle is installed at the end of the guide rod away from the retaining ring, and a locking step is formed between the retaining ring and the locking pin.

[0009] Furthermore, the second elastic element is a return spring, which is sleeved outside the guide rod and located inside the slide groove. The two ends of the return spring elastically abut against the inner end face of the retaining ring and the slide groove or the end face of the guide sleeve, respectively.

[0010] Furthermore, the handle is equipped with a pull hole.

[0011] Furthermore, the first elastic element is a locking spring.

[0012] Furthermore, the stop block is recessed with a fixing hole, one end of the first elastic member is installed in the fixing hole, and the other end of the first elastic member extends out of the fixing hole and elastically abuts against the side of the abutment block.

[0013] Furthermore, a limiting rod is installed on the bottom wall of the fixing hole, with one end of the limiting rod extending out of the fixing hole and used to abut against the side of the contact block.

[0014] Furthermore, the base is equipped with several locking lugs.

[0015] The beneficial effects of this invention are as follows: In practical applications, the locking protrusion on the rotating locking member abuts against the locking step, causing the locking pin on the sliding member to be located on one side of the slot. The second elastic member is in a compressed state, the handle is separated from one end face of the base, the first elastic member is in an extended state, and the elastic force of the first elastic member causes the locking protrusion and the locking step to be firmly locked together. At this time, the latch of the external workpiece to be tested is inserted into the slot and presses against the contact block, causing the contact block to move closer to the stop block along with the rotating locking member and compress the first elastic member. When the locking protrusion on the rotating locking member separates from the locking step, the second elastic member recovers its elasticity. The elastic force of the second elastic member drives the sliding member to move towards the slot until the handle abuts against one end face of the base, causing the locking pin on the sliding member to be inserted laterally into (through) the slot and through the latch of the external workpiece to be tested, so as to lock the latch of the workpiece to be tested in the slot of the base. At this time, the external device can test the locked workpiece. When it is necessary to unlock the workpiece's latch, pull the handle outward, causing the handle to move the sliding member and locking pin away from the slot. This moves the locking pin to one side of the slot, removing the workpiece's latch from the slot. The locking step is located on one side of the locking protrusion. The first elastic member elastically recovers, causing the elastic force of the first elastic member to drive the abutment block to rotate, along with the locking member, away from the stop block. This continues until the locking protrusion on the rotating locking member abuts against the locking step, locking the locking step and facilitating the locking of the next workpiece's latch. This invention has a simple structure, low cost, and is easy to use. It facilitates the rapid locking and unlocking of workpiece latches, and when the locking protrusion and locking step are engaged, the locking pin can remain in the unlocked state for an extended period.

Detailed Implementation To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0020] like Figures 1 to 3 As shown, the present invention provides a detection locking mechanism, which includes a base 1, a stop 2, a first elastic member 3, a rotation locking member 4, a sliding member 5, and a second elastic member 6. A slot 7 is recessed on one side of the base 1. The sliding member 5 is slidably connected to the base 1 and is movably disposed on one side of the slot 7. A locking pin 8 is provided at the end of the sliding member 5 near the slot 7, and a handle 9 is provided at the end of the sliding member 5 away from the slot 7. The handle 9 is located outside one end face of the base 1. The sliding member 5 is elastically connected to the base 1 via the second elastic member 6, which applies a spring force toward the slot 7 to the sliding member 5. The end face of the sliding member 5 away from the handle 9 is positioned between the sliding member 5 and the locking pin 8. A locking step 10 is formed, and a stop block 2 is installed on the other side of the top surface of the base 1. One end of the rotating locking member 4 is rotatably connected to the top surface of the base 1, and the other end of the rotating locking member 4 is provided with an abutment block 11. The two ends of the first elastic member 3 are elastically connected to the abutment block 11 and the stop block 2 respectively. The middle part of the rotating locking member 4 is provided with a locking protrusion 12 for abutting against the locking step 10. When the locking protrusion 12 abuts against the locking step 10, the locking pin 8 is located on one side of the slot 7, and the handle 9 is separated from one end face of the base 1. When the handle 9 abuts against one end face of the base 1, the locking pin 8 extends laterally into or through the slot of the slot 7, and the locking protrusion 12 is separated from the locking step 10.

[0021] In practical applications, the locking protrusion 12 on the rotating locking member 4 abuts against the locking step 10, causing the locking pin 8 on the sliding member 5 to be located on one side of the slot 7. The second elastic member 6 is in a compressed state, the handle 9 is separated from one end face of the seat 1, and the first elastic member 3 is in an extended state. The elastic force of the first elastic member 3 makes the locking protrusion 12 and the locking step 10 firmly locked together. At this time, the latch 21 of the external workpiece to be inspected is inserted into the slot 7 and presses the abutment block 11, causing the abutment block 11 to move closer to the stop block 2 along with the rotating locking member 4. The first elastic element 3 is compressed. When the locking protrusion 12 on the rotating locking element 4 separates from the locking step 10, the second elastic element 6 recovers its elasticity. The elastic force of the second elastic element 6 drives the sliding element 5 to move towards the slot 7 until the handle 9 abuts against one end face of the base 1, so that the locking pin 8 on the sliding element 5 is inserted laterally into (through) the slot of the slot 7 and passes through the locking buckle 21 of the external workpiece to be tested, so as to lock the locking buckle 21 of the workpiece to be tested in the slot 7 of the base 1. At this time, the external device can test the locked workpiece. When it is necessary to unlock the workpiece latch 21, pull the handle 9 outward, causing the handle 9 to move the sliding member 5 and the locking pin 8 away from the slot 7. This moves the locking pin 8 to one side of the slot 7, removing the workpiece latch 21 from the slot 7. The locking step 10 is located on one side of the locking protrusion 12, and the first elastic member 3 elastically recovers. The elastic force of the first elastic member 3 drives the abutment block 11 to rotate the locking member 4 away from the stop block 2 until the locking protrusion 12 on the rotating locking member 4 abuts against the locking step 10 to lock the locking step 10, facilitating the locking of the next workpiece latch 21 to be inspected. The present invention has a simple structure, low cost, and convenient use. It is beneficial for quickly locking and unlocking the workpiece latch 21, and when the locking protrusion 12 is locked against the locking step 10, the locking pin 8 can remain in the unlocked state for a long time.

[0022] In this embodiment, a slide groove 13 communicating with the slot 7 is provided on one side of the top surface of the base 1. The slide groove 13 is located on the side of the slot 7, and the sliding member 5 is movably disposed within the slide groove 13. The slide groove 13 not only guides the movement of the sliding member 5, but also allows the locking pin 8 to retract into the slide groove 13, thereby unlocking the latch 21 of the external workpiece to be inspected.

[0023] In this embodiment, the sliding member 5 includes a retaining ring 14 and a guide rod 15 coaxially connected. A locking pin 8 is connected to the side of the retaining ring 14 away from the guide rod 15. A guide sleeve 16 is embedded in the slide groove 13, and the guide rod 15 slides through the guide sleeve 16. A handle 9 is installed at the end of the guide rod 15 away from the retaining ring 14. A locking step 10 is formed between the retaining ring 14 and the locking pin 8. When the sliding member 5 reciprocates along the slide groove 13, the guide rod 15 and the guide sleeve 16 slide together to improve the movement stability of the sliding member 5.

[0024] In this embodiment, the second elastic element 6 is a return spring, which is sleeved outside the guide rod 15 and located inside the slide groove 13. The two ends of the return spring elastically abut against the inner end face of the retaining ring 14 and the slide groove 13 or the end face of the guide sleeve 16, respectively. This structural design facilitates the installation of the second elastic element 6, makes the second elastic element 6 have good working stability, low cost, and is conducive to the second elastic element 6 applying a spring force towards the slot 7 to the sliding member 5.

[0025] In this embodiment, the handle 9 is provided with a pull hole 17. The pull hole 17 facilitates pulling the handle 9, thereby facilitating the control of the locking pin 8 on the sliding member 5 to move away from the slot 7 and to one side of the slot 7.

[0026] In this embodiment, the first elastic element 3 is a locking spring, which has a simple structure and low cost.

[0027] In this embodiment, the stop block 2 is recessed with a fixing hole, one end of the first elastic member 3 is installed in the fixing hole, and the other end of the first elastic member 3 extends out of the fixing hole and elastically abuts against the side of the contact block 11. This structural design facilitates the assembly and disassembly of the first elastic member 3, resulting in good working stability of the first elastic member 3.

[0028] In this embodiment, a limiting rod 19 is installed on the bottom wall of the fixing hole. One end of the limiting rod 19 extends out of the fixing hole and is used to abut against the side of the abutment block 11. When the abutment block 11 is squeezed to abut against the limiting rod 19, the limiting rod 19 plays a limiting role on the abutment block 11, so that the rotating locking member 4 cannot rotate further, avoiding excessive compression of the first elastic member 3 by the rotating locking member 4, and also avoiding hard impact collision between the abutment block 11 on the rotating locking member 4 and the stop block 2.

[0029] In this embodiment, the base 1 is provided with a plurality of locking lugs 20. The locking lugs 20 are provided to facilitate locking the base 1 to the external structure.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
