Description
【Technical field】
It the utility model is related to the technical field of the technical field of machine components, particularly screw.
【Background technology】
Screw is a kind of conventional part, and is widely used in a variety of occasions.Existing screw easily occurs after tightening
Loosen, it is impossible to ensure long-term fastening effect well, if loosening, which occurs, in some key positions easily causes accident.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of screw for being not easy to loosen, can
Screw is set to be not easy to loosen.
To achieve the above object, the utility model proposes a kind of screw for being not easy to loosen, including hole for injecting glue, head of screw,
Screw rod, spine head, the head of screw bottom centre are connected with screw rod, and screw rod bottom is fixed with spine head, set at the top of the head of screw
Groove is turned, it is in in-line or cross to turn groove, and the hole for injecting glue extends to inside screw through head of screw, and screw rod is provided with
Some side openings, side opening are connected with hole for injecting glue, and the spine rostral wall is provided with some shell fragments, and shell fragment is inclined upwardly.
Preferably, the head of screw, screw rod, spine head, shell fragment are integral type structure, hole for injecting glue is with screw rod positioned at same
On axis.
Preferably, the shell fragment is in spininess, shell fragment quantity is 3-6, and shell fragment bottom is located at same level periphery
On.
The beneficial effects of the utility model：The utility model coordinates side opening can be with by the way that hole for injecting glue is arranged on screw
So that screw can inject glue after tightening so that screw outer surface and by can be by good adhesion, effectively between securing objects
The loosening for preventing screw；The setting of shell fragment causes screw to be not easy to be unscrewed, and ensure that screw is not easy nature loosening.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of front view for the screw for being not easy to loosen of the utility model.
In figure：1- head of screws, 2- screw rods, 3- spines head, 4- hole for injecting glue, 10- turn groove, 30- shell fragments, 40- side openings.
【Embodiment】
Refering to Fig. 1, a kind of screw for being not easy to loosen of the utility model, including hole for injecting glue 4, head of screw 1, screw rod 2, spine head
3, the bottom centre of head of screw 1 is connected with screw rod 2, and the bottom of screw rod 2 is fixed with spine first 3, and the top of head of screw 1, which is provided with, to be turned
Groove 10, it is in in-line or cross to turn groove 10, and the hole for injecting glue 4 is extended to inside screw rod 2 through head of screw 1, set on screw rod 2
There are some side openings 40, side opening 40 is connected with hole for injecting glue 4, and first 3 side wall of spine is provided with some shell fragments 30, and shell fragment 30 is upward
Tilt, the head of screw 1, screw rod 2, spine are first 3, shell fragment 30 be integral type structure, and hole for injecting glue 4 and screw rod 2 are located at same axis
On, the shell fragment 30 is in spininess, and the quantity of shell fragment 30 is 3-6, and the bottom of shell fragment 30 is located on same level periphery.
Utility model works process：
In the course of the work, hole for injecting glue 4 is arranged on screw a kind of screw for being not easy to loosen of the utility model, coordinates side opening
40 can cause screw to inject glue after tightening so that screw outer surface and can be glued well between securing objects
Even, the loosening of screw is effectively prevented；The setting of shell fragment 30 causes screw to be not easy to be unscrewed, and ensure that screw is not easy nature pine
It is dynamic.
Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality
Scheme after type simple transformation belongs to the scope of protection of the utility model.
