Description

Technical Field

[0001] The utility model relates to the technical field of hardware locks, in particular to a rain-proof mechanism for a five-prevention lock used in a substation. Background Technique

[0002] Hardware: Traditional hardware products, also known as "small hardware", refer to five metals, namely gold, silver, copper, iron, and tin. Through manual processing, they can be made into artworks such as knives and swords or metal devices. In modern society, hardware is more extensive, such as hardware tools, hardware parts, daily hardware, building hardware, and security products, etc. The anti-misoperation locks used in various substations are exposed outdoors for a long time, and generally have poor adaptability to climate and environment. From the perspective of the structure of the current protective locks in use, their top protection is relatively perfect (all adopt a snap-on rain-proof cap structure), and rain and sand will not vertically fall into the lock body. However, the bottom protection is seriously insufficient, or even there is no protection. Under the long-term action of wind and sand, rain, and alternating electric fields, rain and sand will enter the lock body along the gaps of the lock, causing phenomena such as sand accumulation, rust, and electrochemical corrosion, making the reliability of the lock significantly worse, resulting in damage phenomena, such as the lock cannot be opened, etc.

[0003] The Chinese patent with the authorization announcement number CN208502482U discloses a replaceable five-prevention lock protective cover. It is provided with a lower cover below the protective lock body. The lower cover is hinged to the protective lock body through a rotating shaft hinge, and the protective lock body and the lower cover are fixed to each other through the complementary action between a positioning boss and a positioning groove. Therefore, the utility model has the characteristics of convenient opening and closing, effectively improves the working efficiency of maintenance personnel, is convenient for comprehensively protecting the five-prevention lock body, effectively improves the protection effect of the utility model, and prolongs the service life of the lock;

[0004] Although it can protect the five-prevention lock, it does not have a mechanism for limiting the gasket. After long-term use, the gasket will turn over in a natural state, resulting in low protection performance. Therefore, a rain-proof mechanism for a five-prevention lock used in a substation is proposed to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a rain-proof mechanism for a five-prevention lock used in a substation, which has the advantages of good protection effect and convenient use, and solves the problems mentioned in the above background technique.

[0006] To achieve the above object, the utility model provides the following technical solution: A rain-proof mechanism for a five-prevention lock used in a substation, including a lock body, a lock handle is arranged at the top of the lock body, and a protection component is arranged inside and at the bottom of the lock body;

[0007] The protection component includes a protection cover hinged to the bottom of the lock body. A connecting column is fixedly connected to the top of the protection cover, and a pushing block is fixedly connected to the top of the connecting column. A cavity is formed inside the lock body, and a telescopic rod is movably connected inside the lock body. A clamping block is fixedly connected to the outer surface of the telescopic rod, a spring is fixedly connected to one side of the clamping block close to the inner wall of the lock body, and a connecting piece is fixedly connected to one end of the telescopic rod.

[0008] Furthermore, a pulling piece is fixedly connected to the outer surface of the connecting piece, and anti-slip lines are provided on the outer surface of the pulling piece.

[0009] Furthermore, an empty groove is formed inside the lock body, a sealing gasket is fixedly connected to the top of the protection cover, and the size of the sealing gasket is smaller than the size of the empty groove.

[0010] Furthermore, the cross-sectional shape of the clamping block is trapezoidal, the cross-sectional shape of the pushing block is trapezoidal, and the inclination angle of the inclined surface of the clamping block is equal to the inclination angle of the inclined surface of the pushing block.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] For the rain-proof mechanism of the five-prevention lock used in the substation, during protection, the protection cover is flipped so that the connecting column and the pushing block are located inside the cavity. When the pushing block contacts the clamping block, the pushing block will move the clamping block towards the side close to the telescopic rod. While the clamping block moves, it compresses the spring. When the connecting column and the pushing block are completely stuck inside the cavity, the compressed spring will reset the telescopic rod and the clamping block. After the clamping block is reset, the top of the clamping block can be clamped with the bottom of the pushing block to fix the protection cover to the bottom of the lock body. When the lock body needs to be opened, the pulling piece is pulled to drive the connecting piece, the telescopic rod and the clamping block to move, the protection cover is flipped, and then the lock body can be opened with a key.
