Buckle type cable explosion-proof box

Abstract

The invention discloses a buckle type cable explosion-proof box. The explosion-proof box comprises an explosion-proof box body formed by assembling a first box body and a second box body, wherein a buckle type connecting fitting is arranged between the first box body and the second box body, the buckle type connecting fitting comprises a first vertical beam, a second vertical beam and a connectingcross beam, the first vertical beam is fixed to the first box body, the second vertical beam is fixed to the second box body and is parallel to the first vertical beam, and the connecting cross beampenetrates through the first vertical beam and then is connected with the second vertical beam to connect the first box body and the second box body into a whole. According to the invention, installation and fastening of the explosion-proof box can be realized conveniently, the size of the fitting can be designed according to the specification of an actual cable explosion-proof box through the buckle type structure, the explosion-proof box can adapt to a fastening problem of explosion-proof boxes of multiple specifications, a traditional bolt structure is replaced with the buckle type explosion-proof box structure, the mounting and dismounting are very convenient, the construction amount can be reduced, the construction time can be saved, and the mounting and dismounting efficiency can beimproved.

Description

Technical field [0001] The invention relates to a cable intermediate joint protection device, in particular to a snap-type cable explosion-proof box. Background technique [0002] With the popularity of electricity, the cable accident rate has also increased. A large number of facts have proved that 80% of accidents are related to cable accessories, especially cable intermediate joints. In view of the key protection problem of the middle joint, the cable explosion-proof box, that is, the middle head protection box, is mainly used to solve the problem. [0003] At present, the mainstream cable explosion-proof box on the market, the cable explosion-proof box is connected by two halves of the box with bolts, and multiple fastening screws are used to fix the connection. In actual installation, multiple screws need to be tightened. The bolt tightening makes this installation method very time consuming on site. Another outstanding problem with the bolt fastening method is that the humi...

Problems solved by technology

[0003] At present, the mainstream cable explosion-proof box on the market, the cable explosion-proof box is spliced ​​together by fastening two halves of the box with bolts, and multiple fastening screws are used to fix the connection. Due to the fact that multiple screws need to be tightened during actual installation, a large number of Bolt tightness makes this installation time consuming to install in the field

Another outstanding problem with the bolt fastening method is that the humid cable channel environment is likely to cause corrosion and rust on the bolts, and it will be very troublesome to disassemble.
