Description
Technical field
The utility model is a kind of connecting head, particularly a kind of fixed connector with screw.
Background technique
Fixed connector of the prior art, traditional protecting jacket mostly is working of plastics, is very easy to damage, and protecting jacket and pipe are socketed to form mutually simultaneously, and fastness is inadequate, easily comes off.
Summary of the invention
Model utility is mainly to solve the deficiencies in the prior art, and a kind of compact structure degree is provided, and multidigit is fixed, a kind of fixed connector with screw that sealing is strong.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of fixed connector with screw, comprise connection housing, the left end of described connection housing is outside thread retention terminal, the inwall of described connection housing right-hand member is internal thread retention terminal, the outer wall of described connection housing right-hand member is provided with more than one maintenance spiral shell seat, the end of described outside thread retention terminal is provided with back-up ring, the inwall of described back-up ring is provided with embedded sealed groove, the outside of described back-up ring is provided with mistake proofing and twists restraining groove, the cross section of described maintenance spiral shell seat is trapezoid shaped, and the right-hand end of described connection housing is provided with reinforcing back-up ring.
Outside thread retention terminal is compared with internal thread, and after installing, intensity promotes to some extent.
Maintenance spiral shell seat attachment screw is used for fixing body, simple to operate, and it is more convenient that more than one maintenance spiral shell seat can make operation simultaneously, can fix a plurality of bodys simultaneously.
Embedded sealed groove is compared with seal washer, when seal ring is encased in embedded sealed groove, plays good retention effect, and sealing effect is promoted to some extent, and embedded structure does not take up space simultaneously, and seal ring can not come off yet simultaneously.
It is in order to prevent excessive tightening that restraining groove is twisted in mistake proofing, makes screw thread distortion, affects firm effect.
The connecting head that this structure is managed and passed by one's way between box for BS.
As preferably, the outer wall of described connection housing is provided with strengthens supporting raised line, and described maintenance spiral shell seat is located to be strengthened supporting on raised line, described maintenance spiral shell seat with strengthen support raised line, maintenance spiral shell seat and be connected housing by strengthening rib, fixing respectively.
As preferably, the material of described connection housing is galvanized part, and the surface of described connection housing is provided with rust preventive coating.Rust preventive coating plays the effect that delays corrosion to a certain extent, increases the service life.
Therefore, a kind of fixed connector with screw that the utility model provides, improves locking fastness, easy to operate, increases the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
