Abstract
The utility model relates to an anti-explosion terminal box, which comprises a base, wherein four installation holes for fixing stretched wires are arranged in the circumferential direction of the base; a base cavity for collecting and connecting the wires is arranged on the base; an opening is formed above the base cavity; a cover board is arranged at the opening in a covering manner; a hemline is arranged at the opening; a plurality of bolt holes are uniformly distributed on the hemline along the edge; coaxial bolt holes are arranged on the cover board at the position corresponding to the bolt holes of the hemline; bolts are used for locking the cover board and the base through the bolt holes of the cover board and the hemline of the opening; and a groove for putting a sealing ring bonded to the hemline of the opening is arranged at the joint between the cover board and the hemline. By adopting the technical scheme, the anti-explosion terminal box disclosed by the utility model is wide in adaptability.
Description
Technical field
The utility model is specifically related to a kind of anti-explosion terminal box.
Background technology
Common anti-explosion terminal box has B level and C level, anti-explosion terminal box comprises base, base circumferentially is provided with installing hole and is used for the locking electric wire, base is provided with assembles the base cavity that connects with electric wire, the base cavity top is provided with opening, be provided with cover plate on the opening, wherein B level anti-explosion terminal box is fixed in base by bolt with cover plate, and C level anti-explosion terminal box to be external screw thread by cover plate consist of with internal thread in the base cavity is threaded, also be provided with sealing ring between cover plate and the base, owing to adapt to different occasions, B level anti-explosion terminal box coupling mechanism force is good, but sealing is poor, and C level anti-explosion terminal box good airproof performance, but coupling mechanism force is poor, and invisible like this has increased manufacturing quantity, increase cost, also reduced anti-explosion terminal box adaptability.
Summary of the invention
For the deficiency that prior art exists, the anti-explosion terminal box that provides a kind of adaptability extensive is provided the purpose of this utility model.
For achieving the above object, the utility model provides following technical scheme: comprise base, base circumferentially is provided with four installing holes and is used for the electric wire that stretches into is fixed, base is provided with assembles the base cavity that connects with electric wire, the base cavity top is provided with opening, vent cover is provided with cover plate, it is characterized in that: described opening part is provided with the shirt rim, described shirt rim is evenly distributed with several bolts hole along the edge, the position that described cover plate is corresponding with the shirt rim bolt hole is provided with coaxial bolt hole, bolt locks cover plate and base by the bolt hole of cover plate and opening shirt rim, and described cover plate and joint place, shirt rim are provided with groove and are used for placing the sealing ring of fitting with the opening shirt rim.
By adopting technique scheme, adopt the cooperation of bolt and sealing ring, reach the advantage of B level anti-explosion terminal box and C level anti-explosion terminal box, both guaranteed coupling mechanism force, also guarantee sealing, applicable to two kinds of use occasions.
The utility model further is set to: described cover plate below is provided with the coaxial fixture block suitable with the opening of base cavity.
By adopting technique scheme, when making cover plate cooperate with base, coaxial fixture block is convenient to installation, be easier to centring, next also increases the intensity that cooperates between fixture block and base.
The utility model further is set to: described shirt rim is evenly distributed with four bolts hole along the edge, described bolt hole and installing hole are interspersed.
By adopting technique scheme, it is best by four bolts cover plate and base to be carried out locking effect, be interspersed to make with installing hole and can not block the visual field when the installing wire, and the Shi Buhui that tights a bolt produces pressure to installing hole and causes distortion.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
