[0002] During the daily maintenance, inspection and switching operations of substations, a large number of unlocking and locking operations for anti-error locks are required. These lock operations are closely related to many aspects of power production and are characterized by large workload and high importance. However, for a long time, due to the uneven quality of anti-error locks and the long-term exposure of anti-error locks used in various substations, there is a general problem of poor adaptability to climate and environment. However, the top protection is relatively complete (all adopt a buckle-type rain cap structure), and rainwater and dust will not fall vertically into the lock body, but dust from the bottom is easy to enter, which will reduce the efficiency of the lock body opening.

[0003] Therefore, a safety protection lock is proposed to solve the above-mentioned drawbacks. Utility Model Content

One end of the L-shaped card plate 210 slides out from the inside of the L-shaped slot 102. The U-shaped plate 2 moves toward the bottom away from the lock body 1 under the elastic action of the first spring 206, and then the lock body 1 can be used.

[0028] The L-shaped card plate 210 is provided so that the L-shaped card plate 210 can slide in and out from the inside of the L-shaped card slot 102 under the action of the user, so that one end of the L-shaped card plate 210 can fix and release the lock body 1 through the L-shaped card slot 102, and then the bottom of the lock body 1 is protected by the U-shaped plate 2, thereby reducing the entry of sand into the interior of the lock body 1, making the process of opening the lock body 1 more convenient.

[0029] In this embodiment, fixing rods 101 are installed on both sides of the lock body 1, which facilitates the installation of the fixing rod 101 on the lock body 1. A first through hole 201 is provided on the U-shaped plate 2, and the fixing rod 101 is located inside the first through hole 201, which facilitates the U-shaped plate 2 to rotate on the fixing rod 101 through the first through hole 201, thereby improving the stability of the U-shaped plate 2 during rotation. A first slideway 202 is provided at the bottom of the lock body 1, and a first sliding block 203 is slidably fitted inside the first slideway 202, which facilitates the first sliding block 203 to slide inside the first slideway 202, thereby improving the stability of the first sliding block 203 during sliding. A first guide rod 204 is installed inside the first slideway 202, and a second through hole 205 is provided on one side of the first sliding block 203, and the first guide rod 204 is located inside the second through hole 205, which facilitates the first sliding block 203 to slide on the first guide rod 204 through the second through hole 205, thereby improving the stability of the first sliding block 203 during sliding.

[0030] A second slide 211 is provided at the bottom of the lock body 1 of the present embodiment, and a second guide rod 207 is installed inside the second slide 211, which facilitates the installation of the second guide rod 207 inside the second slide 211. The L-shaped card plate 210 is slidably matched inside the second slide 211. A third through hole 209 is provided on one side of the L-shaped card plate 210, and the second guide rod 207 is located inside the third through hole 209, which facilitates the L-shaped card plate 210 to slide on the second guide rod 207 through the third through hole, thereby improving the stability of the L-shaped card plate 210 when sliding. A second spring 208 is installed between one side of the L-shaped card plate 210 and the side wall of the second slide 211, which facilitates the L-shaped card plate 210 to reset under the elastic action of the second spring 208. The second spring 208 is sleeved on the peripheral side of the second guide rod 207, which facilitates the sleeve of the second spring 208 on the peripheral side of the second guide rod 207.
