[0002] Explosion-proof junction box Explosion-proof junction box model: BHD51 is characterized by cast aluminum alloy shell, surface spraying, beautiful appearance, the existing application number is 201320127846.2 is an explosion-proof junction box, the shell is provided with external threads and the cover is provided with The internal thread can hide its joint surface under the cover, so as to achieve the effect of not being easy to enter the water and improve the protection performance. However, the sparks caused by the short circuit of such a junction box will cause an explosion inside the junction box, and the junction box cannot be damaged. The internal explosion gas is used for buffering, which is easy to damage the junction box, and it is easy to break the connection of the external connection threading pipe, which is not convenient for users to use

Abstract

The invention discloses an explosion-proof junction box, which comprises a box body, an outer threading pipe connecting mechanism and a buffer mechanism. The outer threading pipe connecting mechanismcomprises four pipelines, threaded grooves are formed in the inner side faces of the four pipelines, and blocking mechanisms are arranged on the inner side faces of the four pipelines; the buffer mechanism comprises a fixed sleeve, a spring is placed in the fixed sleeve, a disc is arranged at one end in the spring, the disc is slidably connected to the interior of the fixed sleeve, a connecting column is arranged on the side face in the disc, a buffer plate is arranged at the inner end of the connecting column, and the buffer plate is connected to the side face of the fixed sleeve in a sleeving mode. The four pipelines are respectively arranged on the four side surfaces of the box body, and the fixed sleeve is fixedly arranged on the inner side wall of the box body, the explosion-proof junction box can buffer gas generated after explosion occurs in the junction box, prevent the junction box from being damaged, reinforce the fracture of the connection part of an external connection threading pipe, and is convenient for a user to use.

Description

technical field [0001] The invention relates to the technical field of explosion-proof junction boxes, in particular to an explosion-proof junction box. Background technique [0002] Explosion-proof junction box Explosion-proof junction box model: BHD51 is characterized by cast aluminum alloy shell, surface spraying, beautiful appearance, the existing application number is 201320127846.2 is an explosion-proof junction box, the shell is provided with external threads and the cover is provided with The internal thread can hide its joint surface under the cover, so as to achieve the effect of not being easy to enter the water and improve the protection performance. However, the sparks caused by the short circuit of such a junction box will cause an explosion inside the junction box, and the junction box cannot be damaged. The internal explosion gas is used for buffering, which may easily damage the junction box and easily break the joint of the external connection threading pip...
