Description

A lock base for a resilient locking pin Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a lock seat for a resilient locking pin. Background Technology

[0002] A resilient locking pin lock seat is a mechanical component used in automobile manufacturing and repair. It is used to quickly fix and release various parts of a car (such as doors, hoods, seats, etc.). This lock seat achieves its fixing function through a resilient locking pin, and is easy to operate and highly reliable.

[0003] When using a spring-loaded locking pin, the spring-loaded locking pin is usually inserted into the lock hole of the locking pin holder. Then, under the action of the spring, the spring-loaded locking pin automatically pops out and finally locks into the lock hole, thereby achieving the locking function. When removing the spring-loaded locking pin, the operator presses the button or operating handle to retract the spring-loaded locking pin back into the locking pin holder. While the spring-loaded locking pin is in the retracted state, the spring-loaded locking pin can be pulled out of the locking pin holder to complete the release operation.

[0004] In existing resilient locking pin lock seats, although the resilient locking pin can be retracted into the lock seat by pressing a button or operating a handle during use, the locking pin may also retract into the resilient locking pin lock seat due to accidental contact (such as tool collision, human misoperation, etc.). This can cause the automotive parts to loosen or fall off unexpectedly, ultimately affecting the normal operation of the vehicle. To address this, we propose a resilient locking pin lock seat. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a lock seat for an elastic locking pin. It can lock and fix the push plate through the self-locking of the worm gear structure, replacing the traditional method of retracting the elastic locking pin by pressing the button with external force. This solves the problem of accidental retraction of the elastic locking pin due to accidental contact, and will not cause the automotive components to loosen or fall off accidentally, ensuring the normal operation of the vehicle. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lock seat for an elastic locking pin, comprising a seat body, a guide groove provided on the left side of the upper end of the seat body, a lock hole provided on the right side of the inner arc surface of the guide groove, and a pressing mechanism.

[0007] The pressing mechanism includes a mounting rod, an adjusting seat, a crossbar, and a mounting groove. The mounting groove is located on the right side of the seat body. The mounting rod is rotatably connected to the middle of the right wall of the mounting groove. Adjusting seats are respectively provided on the front and rear sides of the outer arc surface of the mounting rod. Crossbars are slidably connected to the front and rear sides of the right wall of the lock hole. The right ends of the two crossbars are respectively in contact with the inclined surfaces provided on the left ends of the horizontally adjacent adjusting seats. The push plate can be locked and fixed by the worm gear structure self-locking, which replaces the traditional method of pressing the button with external force to retract the elastic locking pin. This solves the problem of accidental retraction of the elastic locking pin due to accidental contact, and will not cause the automotive components to loosen or fall off accidentally, ensuring the normal operation of the vehicle.

[0008] Furthermore, the pressing mechanism also includes a push plate, which is slidably connected to the bottom wall of the lock hole. The left end of the crossbar is fixedly connected to the right end of the push plate, which can drive the elastic locking pin to retract.

[0009] Furthermore, the pressing mechanism also includes a limiting plate and a limiting rod. The limiting rods are respectively disposed on the upper and lower sides of the right end of the push plate, and the right ends of the two limiting rods are in contact with the right wall of the lock hole. The limiting plate is respectively disposed on the right side of the outer arc surface of the crossbar to prevent the crossbar from separating from the adjusting seat.

[0010] Furthermore, the pressing mechanism also includes springs, which are respectively disposed between the right end of the push plate and the right wall of the lock hole. The springs are all sleeved on the outside of the left end of the crossbar. The tension generated by the spring contraction can drive the push plate to move and reset.

[0011] Furthermore, a worm gear is provided on the right side of the outer arc surface of the mounting rod, and a worm is provided on the lower side inside the mounting groove. The worm gear and the worm are meshed and connected, and the mounting rod can be rotated through the worm gear.

[0012] Furthermore, a connecting rod is rotatably connected to the right side of the front wall of the mounting groove, and a worm gear is fixedly connected to the rear side of the outer arc surface of the connecting rod. An adjustment knob is provided at the front end of the connecting rod, which can drive the worm gear to rotate.

[0013] Furthermore, fixing plates are respectively provided on the lower sides of the front and rear ends of the base, and mounting holes are respectively provided on the upper ends of the fixing plates, which can be used to install and fix the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This lock seat for the resilient locking pin has the following advantages:

[0015] The push plate can be locked and fixed by a worm gear structure, which replaces the traditional method of pressing a button to retract the elastic locking pin. This solves the problem of accidental retraction of the elastic locking pin due to accidental contact, and will not cause the automotive components to loosen or fall off, ensuring that the vehicle can operate normally.

The right ends of the two crossbars 43 are respectively in contact with the inclined surfaces provided on the left ends of the horizontally adjacent adjusting seats 42. Pressing mechanism 4 also includes a push plate 44, which is slidably connected to the bottom wall of the lock hole 3. The left ends of the crossbars 43 are fixedly connected to the right ends of the push plate 44. Pressing mechanism 4 also includes a limiting plate 45 and a limiting rod 46. The positioning rods 46 are respectively located on the upper and lower sides of the right end of the push plate 44. The right ends of the two positioning rods 46 are in contact with the right wall of the lock hole 3. The positioning plates 45 are respectively located on the right side of the outer arc surface of the crossbar 43. The pressing mechanism 4 also includes springs 47. The springs 47 are respectively located between the right end of the push plate 44 and the right wall of the lock hole 3. The springs 47 are all sleeved on the outside of the left end of the crossbar 43. The push plate 44 can be locked and fixed by the self-locking structure of the worm gear 6, which replaces the traditional method of pressing the button with external force to retract the elastic locking pin. This solves the problem of the elastic locking pin accidentally retracting due to accidental contact, and will not cause the automotive components to loosen or fall off accidentally, ensuring that the vehicle can operate normally.

[0023] Wherein: a worm wheel 5 is provided on the right side of the outer arc surface of the mounting rod 41, and a worm 6 is provided on the lower side inside the mounting groove 48. The worm wheel 5 and the worm 6 are meshed and connected. During the rotation of the worm 6, the worm wheel 5 will be driven to rotate through the meshing connection. The worm wheel 5 drives the mounting rod 41 to rotate counterclockwise.

[0024] The mounting groove 48 has a connecting rod 7 rotatably connected to the right side of its front wall. A worm gear 6 is fixedly connected to the rear side of the outer arc surface of the connecting rod 7. An adjustment knob 8 is provided at the front end of the connecting rod 7.

During the use of the elastic locking pin lock seat, the operator inserts the elastic locking pin on the vehicle into the guide slide 2. When the lower end of the elastic locking pin contacts the bottom wall of the guide slide 2, the elastic locking pin automatically pops out from the inside of the guide slide 2 under the action of the elastic component, and finally gets stuck in the lock hole 3, thereby achieving the locking function. When it is necessary to pull out the elastic locking pin, the operator uses an external tool to rotate it. Turn the adjustment knob 8, which drives the connecting rod 7 to rotate. The connecting rod 7 drives the worm gear 6 to rotate. During the rotation, the worm gear 6 drives the worm wheel 5 to rotate through the meshing connection. The worm wheel 5 drives the mounting rod 41 to rotate counterclockwise. The mounting rod 41 drives the adjusting seat 42 to rotate counterclockwise. During the rotation of the adjusting seat 42, the adjusting seat 42 will push the crossbar 43 to the left, thereby causing the crossbar 43 to drive the push plate 44 to move to the left. The spring 47 extends, and the push plate 44 drives the elastic locking pin to retract back into the guide groove 2. With the elastic locking pin in the retracted state, the elastic locking pin can be pulled out.
