The invention discloses a gravity self-locking device for a distribution box. The gravity self-locking device comprises the distribution box with a box door. The box door is provided with a lock hole.The lock hole is provided with a fastening screw pipe inserted and connected in the lock hole, and the fastening screw pipe is fixed to the lock hole through a limiting wire ring. A rotation shaft ismovably inserted and connected in the inner diameter position of the fastening screw pipe. A lock bar is arranged at one end of the rotation shaft, and the other end of the rotation shaft is providedwith a self-locking nut which is in screw joint to the rotation shaft. A lock nut is arranged on the outer side of the self-locking nut, and a pin hole I is formed in one side of the lock nut. The pin hole I and a pin hole II in one end of the rotation shaft are fixed in an inserted and connected manner through a fixing pin. The lock nut is fixedly connected with one end of a handle, and the other end of the handle is provided with a balance weight ball. The handle corresponds to the lock bar in a 90-degree staggering manner. The lock bar corresponds to the handle in a 90-degree staggering manner through the rotation shaft. The handle is constantly kept in a natural drooping state under the actions of the balance weight ball and earth gravity, accordingly, it is guaranteed that the lock bar is in a horizontal locking state, influences from earthquake waves are avoided, and self-locking of the box door of the distribution box is achieved.
Description
Technical field [0001] The invention belongs to the technical field of power distribution box locks, and relates to a gravity self-locking device for a power distribution box. Background technique [0002] In the prior art, a certain degree of seismic waves are generated during blasting operations of mining ore underground in non-metallic mines, and the seismic waves may cause fluctuations in the crust within a certain range. In the process of underground mining operations, many electric equipments, especially distribution boxes, will be used underground. Because the material of the distribution box lock core is aluminum, the lock core will be broken and damaged under the influence of seismic waves for a long time. The door of the distribution box is open and cannot be closed, which affects the built-in electronic components, and also seriously affects the personal safety of the operators, posing safety risks. Summary of the invention [0003] The purpose of the present invent...
