Description
Technical field
A kind of bolt is the utility model is related to, specifically a kind of tube clamps screw cap-falling-proof fastening bolt.
Background technology
Tube clamps are a kind of connectors for being used to connect two tubes.Existing tube clamps are fastened by bolt and nut
Hold tightly on the outside of pipe, to realize the connection between two tubes.When needing to pull down tube clamps, then need nut from bolt
Back out.Since common bolt and nut are two individuals being separated from each other, when tube clamps are pulled down, nut and bolt separation, holds
Easily nut or bolt are lost, caused inconvenient for use.
Utility model content
The utility model provides a kind of tube clamps screw cap-falling-proof fastening bolt.
The purpose of this utility model is to solve existing tube clamps to be fastened using plain bolt nut, and bolt and nut are
Two individuals being separated from each other, nut or bolt are easily lost, cause the problem of inconvenient for use.
Technical solution is used by the utility model solves its technical problem：A kind of tube clamps are fastened with screw cap-falling-proof
Bolt, including bolt, nut, the bolt include bolt column and bolt head, and the bolt head is arranged on bolt top end, the spiral shell
Hitching post is equipped with screw thread, and the nut is screwed on the screw thread of bolt column, it further includes anti-falling piece, and the anti-falling piece includes anti-falling piece
Head and anti-falling piece column, the anti-falling piece head are arranged on anti-falling piece top end, and the anti-falling piece column is equipped with anti-Leave out thread, the bolt
Column bottom is equipped with card slot, and card slot screw thread is equipped with the card slot, and the anti-falling piece column is arranged in card slot, the anti-Leave out thread and card
Groove screw thread matches.
Preferably, the width of the anti-falling piece head is more than the screw hole width of nut.
The beneficial effects of the utility model are：Tube clamps screw cap-falling-proof fastening bolt described in the utility model passes through
Anti-falling piece is set in bolt column bottom, nut is spacing between bolt head and anti-falling piece head, overcome plain bolt nut
Because being be separated from each other individual and the defects of easily lose, screw cap-falling effectively prevent.
Brief description of the drawings
Fig. 1 is one of the utility model bolt arrangement schematic diagram (anti-falling piece is screwed into bottom).
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is two (anti-falling piece back-out certain distances) of the utility model bolt arrangement schematic diagram.
Fig. 4 is the sectional view of Fig. 3.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
As shown in the figure, there is provided the embodiment of the utility model tube clamps screw cap-falling-proof fastening bolt, including bolt,
Nut 3, the bolt include bolt column 1 and bolt head 2, and the bolt head 2 is arranged on 1 top of bolt column, on the bolt column 1
Equipped with screw thread, the nut 3 is screwed on the screw thread of bolt column 1, it further includes anti-falling piece 4, and the anti-falling piece 4 includes anti-falling piece head
41 and anti-falling piece column 42, the anti-falling piece first 41 be arranged on 42 top of anti-falling piece column, the anti-falling piece column 42 is equipped with anti-Leave out thread,
1 bottom of bolt column is equipped with card slot 5, and card slot screw thread is equipped with the card slot 5, and the anti-falling piece column 42 is arranged in card slot 5,
The anti-Leave out thread matches with card slot screw thread.
The width of the anti-falling piece first 41 is more than the screw hole width of nut 3.
In actual use, since the width of anti-falling piece head is more than the screw hole width of nut, nut is limited in spiral shell
Between bolt head and anti-falling piece head, when script needs to pull down by the tube clamps that bolt and nut fastening are held tightly on the outside of pipe,
Only anti-falling piece need to be screwed out into certain distance out of bolt column bottom card slot, both not exclusively screw out separation, then from bolt column
On back out nut, tube clamps, which loosen, to be removed, and nut is still between anti-falling piece head and bolt head at this time, and nut and bolt will not be because
Lose to be separated from each other.
