Description

Technical Field

[0001] The utility model relates to the technical field of cable protection boxes, in particular to a waterproof and explosion-proof protection box for a cable intermediate joint. Background Art

[0002] The waterproof and explosion-proof protection box for the cable intermediate joint refers to a device installed in the middle of the cable. It is mainly used to connect cables and plays the role of connection, fixation, and sealing. The structure of the joint box together forms a reliable connection unit to ensure the safe, stable and efficient transmission of the cable joint. Since the protection box will be buried underground, it requires certain waterproof and explosion-proof functions.

[0003] According to the description of a waterproof explosion-proof box for a cable intermediate joint disclosed on the patent website (authorization announcement number: CN215817474U), "The utility model relates to the field of cable joint protection technology, and discloses a waterproof explosion-proof box for a cable intermediate joint, including a protection box, a cable assembly with one end penetrating and extending to the right side thereof is arranged on the left side of the protection box, and two installation boxes are arranged on the front side of the protection box and are symmetrically distributed on the left and right. In the waterproof explosion-proof box for the cable intermediate joint, the waterproof belt and armor belt on the outside of the cable line can play a waterproof role, and the sealed protection box can play an explosion-proof role. By rotating the handle, the threaded rod is driven to rotate. Under the action of the threaded hole, the threaded rod drives the moving plate to move downward, and the first shape block moves downward with the moving plate at the same time, so that the second trapezoidal block slidably connected to the first trapezoidal block drives the moving block to move right, and the moving block drives the clamping block to move right until the clamping block is fully engaged with the limit rod, and the limit rod can be fixed inside the installation box, that is, the protection box is closed, and the purpose of facilitating the installation of the protection box is achieved."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, since the device drives the first trapezoidal block to descend by rotating the threaded rod, the card block is carded into the inside of the limit rod to fix the protection box. However, the protection box is generally buried underground, and moisture absorbed underground affects the surface of the threaded rod and causes rust. When the protection box needs to be opened, the threaded rod cannot be rotated due to rust, so the card block cannot be separated from the limit rod, resulting in the protection box being unable to be opened. The use of the utility model is limited. Therefore, it is necessary to improve a waterproof and explosion-proof protection box for the cable intermediate joint to solve the above problems.
