Technical Field
[0001] The present application relates to the technical field of pin tumbler locks, and in particular to a corrosion-resistant and anti-collision stainless steel pin tumbler lock. Background Art
[0002] The pin tumbler lock is a common lock. Its main feature is that it uses a series of pins (small steel balls or small metal pillars) to prevent the lock cylinder from rotating, thereby achieving the purpose of locking. The working principle of the pin tumbler lock is relatively simple, but it provides sufficient security and is widely used in various door locks, drawer locks, small safes, etc.
[0003] At present, the anti-collision of the pin tumbler lock can rely on the lock body and the mounting lock block outside the lock core for anti-collision protection, but dust is easily accumulated at the lock hole of the lock body, and the pin tumbler lock used outdoors will also accumulate rainwater in thunderstorms, causing corrosion and rust in the lock hole, causing problems in the use of the pin tumbler lock. Therefore, a corrosion-resistant and anti-collision stainless steel pin tumbler lock is designed to solve the above-mentioned problems. Utility Model Content

[0021] The following is combined with Figure 1-5 This application is described in further detail.
[0022] The present application discloses a corrosion-resistant and anti-collision stainless steel pin tumbler lock. Figure 1-5 A corrosion-resistant and anti-collision stainless steel pin tumbler lock includes a pin tumbler lock body 1. A lock hole is provided on one side of the pin tumbler lock body 1. The lock hole is used to connect with a lock rod, so that the lock rod can be inserted into the lock hole to complete the locking. Protective plates 4 are slidably provided on both sides of the upper part of the lock hole. A mounting groove is provided on the pin tumbler lock body 1 near the lock hole. The rear of the protective plate 4 is fixedly connected to a mounting plate 3. The mounting plate 3 and the mounting groove are slidably connected. The protective plate 4 can cover the lock hole after moving, so that the lock hole is protected when it is separated from the lock rod.
[0023] One side of the installation groove is connected to a gear 7, and the middle part of one side of the gear 7 is fixedly connected to a screw rod 6, which is threadedly connected to a moving block 5. The moving block 5 is slidably connected to the installation groove, and the moving block 5 is fixedly connected to the protective plate 4. The screw rod 6 is driven to rotate by the gear 7, so that the screw rod 6 drives the moving block 5 to move, and then the moving block 5 drives the protective plate 4 to move and cover the lock hole;
[0024] By adopting the above technical solution, a gear plate 8 is meshed at the rear of the gear 7, and the gear plate 8 drives the gear 7 to rotate, so that the gear 7 can drive the screw rod 6 to rotate, which is conducive to driving the gear 7 to rotate. The lower end of the gear plate 8 is fixedly connected to the elastic sheet 9, and the lower end of the elastic sheet 9 is fixedly connected to the inner wall of the mounting groove.
[0025] The elastic sheet 9 is used to provide thrust to drive the gear plate 8 to rise, thereby driving the gear 7 to rotate and restore.
[0026] By adopting the above technical solution, a collar 2 is slidably mounted on the lock rod of the pin lock body 1, one side of the collar 2 is fixedly connected to the support plate 21, and the lower end of the support plate 21 is fixedly connected to the insertion rod 22. The insertion rod 22 is used to push the gear plate 8 down, so that the gear plate 8 drives the gear 7 to rotate.
[0027] By adopting the above technical solution, the two protection plates 4 close to one side are both symmetrical cover plates, and the protection plates 4 block the lock holes after moving.
[0028] The implementation principle of a corrosion-resistant and anti-collision stainless steel pin tumbler lock according to the embodiment of the present application is as follows: when the pin tumbler lock needs to be used, the lock rod is rotated to align the lock rod with the lock hole, and then the collar 2 is pushed to make the collar 2 descend and drive the support plate 21 to descend, and the support plate 21 drives the insertion rod 22 to descend, so that the insertion rod 22 enters the installation groove and squeezes the gear plate 8 located in the installation groove, so that the gear plate 8 descends and drives the gear 7 to rotate, and the gear 7 drives the screw rod 6 to rotate, so that the screw rod 6 drives the moving block 5 to move, and the moving block 5 drives the mounting plate 3 to move, and the mounting plate 3 drives the protection plate 4 to move, so that the protection plate 4 moves and moves away from the lock. The hole is formed by the protective plate 4, so that the protective plate 4 no longer blocks the lock hole, and then the locking rod is pressed to make the locking rod enter the lock hole; thereafter, the collar 2 can be loosened so that the collar 2 no longer uses the insertion rod 22 to apply pressure to the gear plate 8. At this time, the elastic sheet 9 pushes the gear plate 8 and makes the gear plate 8 have an upward trend. When the pin lock is opened, the locking rod is separated from the lock hole. At this time, the gear plate 8 rises and then recovers, and drives the gear 7 to rotate, so that the gear 7 drives the screw rod 6 to rotate again, and the screw rod 6 drives the moving block 5 to move, so that the moving block 5 drives the protective plate 4 to recover and cover the lock hole again, thereby protecting the lock hole.
