Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to quick-release padlocks. Background Technology

[0002] Car interiors and exteriors often require extension components, especially motorhomes which have a high demand for extension structures. Traditional extension structures use mounting plates that are bolted or welded to the vehicle body structure, which have limited functionality and do not offer quick-release or quick-installation capabilities. Furthermore, if the quick-release mechanism is not designed properly, it may be accidentally activated, posing a safety hazard. When additional extension structures are needed, new mounting plates must be replaced, making it inconvenient to use. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 A quick-release padlock includes a back plate 1 and a lock body assembly. The lock body assembly includes a storage frame 2, side plates 3, springs 4, guide rods 5, sliders 6, positioning heads 7, and a lock body frame 8. The lock body frame 8 is provided on the front of the back plate 1. The lock body frame 8 has a T-shaped groove with an upper opening. The back plate 1 has a first positioning hole that communicates with the T-shaped groove. One end of the positioning head 7 passes through the first positioning hole, and the other end of the positioning head 7 has a slider 6. The back side of the back plate 1 also has a storage frame 2 for storing the positioning head 7 and the slider 6. The left and right sides of the storage frame 2 are also provided with side plates 3 connected to the back plate 1. The storage frame 2 also has a spring 4 inside. The two ends of the spring 4 are respectively connected to the inner wall of the storage frame 2 and the slider 6. The back side of the slider 6 also has a guide rod 5 that passes through the storage frame 2. The guide rod 5 is slidably connected to the storage frame 2.

[0024] This quick-release padlock uses spring 4 to drive the positioning head 7 to cooperate with the T-slot, realizing the quick installation, locking and removal of the extension parts. Its working principle can be divided into three stages: installation and positioning, locking and holding, and quick removal.

[0025] The back plate 1 is connected to the vehicle body by bolts. The storage frame 2 has side plates 3 connected to the back plate 1 on both sides. The vehicle body has a mounting groove for the storage frame 2 and the guide rod 5 protruding from the storage frame 2. The spring 4 is in a naturally extended state, pushing the slider 6 and the positioning head 7 forward. One end of the positioning head 7 passes through the first positioning hole of the back plate 1 and protrudes into the T-shaped groove of the lock body frame 8. The other end is fixedly connected to the slider 6.

[0026] When the positioning head 7 is pushed into the storage frame 2, the slider 6 slides in the storage frame 2, the guide rod 5 passes through the storage frame 2, the spring 4 contracts, the mounting seat of the extension part is inserted into the lock body frame 8, and the T-slot, in conjunction with the reset positioning head 7, can stably limit the mounting seat of the extension part.

[0027] When disassembling, the positioning head 7 needs to be pushed against and put into the storage frame 2, and then the mounting base of the extension part can be taken out.

[0028] In this embodiment, a guide component is also provided in the T-shaped groove. The guide component includes an inclined plate 9 and a mounting plate 10. The inclined plate 9 is provided above the mounting plate 10. A notch is also provided on the back plate 1. The inclined plate 9 is tilted into the notch. A second positioning hole is also provided on the mounting plate 10. The positioning head 7 passes through the second positioning hole. When the mounting plate 10 is fully inserted into the T-shaped groove, its second positioning hole is coaxial with the first positioning hole of the back plate 1. The spring 4 resets and pushes the positioning head 7 through the two holes to form a mechanical lock. The inclined plate 9 facilitates the installation seat of the extension part to enter the T-shaped groove. A rounded edge 11 is provided on the upper edge of the T-shaped groove.

[0029] In this embodiment, the positioning head 7 protruding from the second positioning hole is also provided with a slope 12. When the mounting base of the extension is inserted into the T-shaped groove, the slope 12 abuts against the positioning head 7 and is retracted into the storage frame 2. The upper part of the positioning head 7 is provided with a slope 12, while the lower part is a horizontal surface, which can prevent the mounting base of the extension from coming out.

[0030] In actual use, the upper part of the front of the lock body frame 8 is vertical, and the lower part of the front of the lock body frame 8 is provided with a transition surface 13. The vertical surface ensures stable support for the expansion component, and the transition surface 13 makes it easy to hold the expansion component for assembly and disassembly.

[0031] In this embodiment, the slider 6 is rectangular to prevent it from rotating.
