Description

Technical Field

[0001] The utility model relates to the field of devices for preventing accidental or unauthorized actions, in particular to a gate valve protection box with a built-in lock. Background Art

[0002] At present, the gate valve is usually adjusted by a handle, but the handle is directly exposed to the outside world. In some relatively public places, it is easy for non-staff to touch it by mistake, causing safety hazards and thus causing unnecessary losses. In addition, for gate valves that do not need to be adjusted for a long time, the handle may be touched by mistake due to environmental factors, further affecting the use effect of the device. In traditional gate valve protection boxes, the lock is usually located outside the box, which is easily affected by harsh environments, high temperatures, low temperatures and other factors, resulting in damage to the lock. When the protection box is to be opened, it cannot be opened immediately, affecting the effective adjustment of the gate valve. Summary of the invention

[0003] The purpose of the utility model is to provide a gate valve protection box with a built-in lock, in which a lock is directly installed inside a box, achieving a perfect combination of the lock and the gate valve, which not only improves the safety and stability of the gate valve, but also improves the convenience and efficiency of operation, and effectively solves the safety hazards and impaired use effects of existing gate valves.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A gate valve protection box with a built-in lock comprises an upper box body, a lower box body and a handle, wherein the interiors of the upper box body and the lower box body are both hollow structures, and the outer sides of the upper box body and the lower box body are connected by hinges;

[0006] A fixing tongue is provided on the inner side of the opening of the upper box body, the fixing tongue extends downward, and a fixing slot is provided on the front end of the fixing tongue;

[0007] The bottom of the lower box body is provided with a gate valve hole and a mounting hole matching the gate valve; the lower box body is provided with a handle hole on one side of the hinge, the handle hole is rectangular and semicircular, a lock is provided on the inner side of the opening side, the key hole of the lock is opposite to the handle hole, and the lock tongue extending from the lock matches the fixed card slot;

[0008] The handle consists of a T-handle, a key and a plum nut. The front end of the T-handle is provided with an arc-shaped groove, which matches the key. The side of the arc-shaped groove is provided with mounting screw holes. The key is placed in the arc-shaped groove, and the plum nut passes through the hanging hole on the key to be fixedly connected to the T-handle.

[0009] There are 6 to 12 mounting holes.

[0010] Before use, the employee first installs a gate valve protection box with a built-in lock on the gate valve through the mounting hole, and the gate valve handle is in the box body through the gate valve hole. To lock the protection box, the employee first fixes the key corresponding to the lock on the T-handle, then puts down the upper box body, closes the protection box, and then passes the handle through the handle hole, inserts the key at the front end of the handle into the keyhole, turns the handle, extends the lock tongue into the fixed card slot of the fixed tongue, and locks the protection box. To open the protection box, just do the reverse operation. It is simple to operate, can prevent random operation, effectively improve the safety of the overall equipment, and can be durable in harsh environments such as outdoor, high temperature, and low temperature. Beneficial Effects

[0011] The utility model directly installs the lock inside the box, realizing the perfect combination of the lock and the gate valve, which not only improves the safety and stability of the gate valve, but also improves the convenience and efficiency of operation.

[0012] The utility model has enhanced safety. By embedding the lock in the protection box, the handle is effectively prevented from being directly exposed to the outside world. Non-staff cannot touch the handle, thereby reducing the safety hazard caused by accidental touch. Only authorized personnel can open the protection box, ensuring the safety and stable operation of the gate valve.

[0013] The utility model has an anti-damage function. In the traditional gate valve protection box, the lock is usually located outside the box, which is easily affected by harsh environment, high temperature, low temperature and other factors, resulting in damage to the lock. The built-in protection box of the lock solves this problem. The lock is inside the box and will not be affected by the external environment, extending the service life of the lock.

[0014] The utility model can be operated quickly, and the built-in protection box of the lock is reasonably designed and easy to operate. Authorized personnel can quickly open the protection box to adjust and operate the gate valve. No additional tools or steps are required, which improves the efficiency and convenience of operation.

[0015] The utility model has a multifunctional application, and the built-in protection box of the lock is suitable for various environments and occasions. Whether it is outdoors or indoors, whether it is high temperature or low temperature, the protection box can effectively protect the gate valve and ensure its normal operation.

[0016] The handle end of the key of the utility model is placed in the arc-shaped groove, and the plum nut passes through the hanging hole on the key and is fixedly connected with the T-handle, so that the tooth end of the key can be ensured to face forward without being eccentric, and the lock can be opened conveniently.

[0017] The handle hole of the utility model is a rectangle plus a semicircle, which can ensure that the handle enters the box and the key is in the correct direction.

[0018] The utility model has a one-to-one correspondence between the lock and the key, and the key is fixedly connected to the T-handle when the protection box is opened or closed, thereby avoiding the problem of one universal key opening multiple locks. BRIEF DESCRIPTION OF THE DRAWINGS
