Abstract
The utility model discloses an anti-dismounting bolt which comprises an anti-dismounting head part and a screw rod, wherein the anti-dismounting head part comprises an oblate head, a hexagon head and a twisting part which is connected with the oblate head and the hexagon head. The hexagon head of the anti-dismounting head part of the anti-dismounting bolt can be twisted off after being fastened and the leaved oblate head is inconvenient to dismount by virtue of a twisting tool, so that an effect of preventing the anti-dismounting bolt from being dismounted is achieved, and a potential safety hazard caused by an operation of adjusting the bolt by a user without permission and the influence on judgment for accident liability are further avoided.
Description
Technical field
The utility model relates to the link field, particularly a kind of anti-demounting bolt.
Background technique
In present various kinds of equipment, machinery; Exist a lot of structures in the debug process of dispatching from the factory, need adjust; The general bolt that adopts is locked; Be not allow the user privately the bolt of tightening to be adjusted after dispatching from the factory, because this adjustment may cause a series of other problemses, especially to its function of use and reliability aspect.More serious, possible user or other non-professional adjustment may cause great potential safety hazard, are adjusted privately such as the motor of an automobile to cause serious accident, but perhaps all can damage for the passenger of whole automobile.
Manufacturer generally adopts modes such as increasing lead sealing, stop-off lacquer not allow the user to adjust privately at present, otherwise the fault that occurs is responsible for by the user.But the bolt that can't guarantee lead sealing, stop-off lacquer in the practical operation causes potential safety hazard not by random dismounting adjustment.Simultaneously, modes such as lead sealing, stop-off lacquer have certain restorability, and the fault that the difficult judgement that goes wrong is occurred has absolute relation with the quilt adjustment.
The model utility content
The technical problem that the utility model solves provides a kind of easy for installation, anti-demounting bolt that the tamper performance is good.
For achieving the above object, according to the utility model a kind of anti-demounting bolt is provided, comprising: tamper head and screw rod, the tamper head comprises: oval head is with hexagon head and be connected oval head and the portion of twisting into two parts of hexagon head.
Further, the portion of twisting into two parts forms through processing deep trouth between oval head and hexagon head.
Further, the portion of twisting into two parts is cylindric or taper.
Technological scheme according to the utility model; Owing to can twist into two parts after the hexagon head of the tamper head of this anti-demounting bolt tightens; And the oval head that stays inconvenience is through the screwing tool dismounting; Reach the effect that this anti-demounting bolt can't be dismantled, and then avoided the user to adjust this bolt privately and caused potential safety hazard, influenced the judgement of accident responsibility.

Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
Referring to Fig. 1 to Fig. 3, this anti-demounting bolt comprises: tamper head 1 and screw rod 2.Wherein, tamper head 1 is divided into two-part, comprising: oval head 11 and hexagon head 12, and oval head 11 is connected with screw rod 2, forms an oval head bolt; Hexagon head 12 is connected on the oval head 11 through the portion of twisting into two parts 13; This is twisted into two parts portion 13 and forms through processing deep trouth between oval head 11 and hexagon head 12, is cylindric or taper, through the degree of depth of control deep trouth; Both guaranteed that the hexagonal part can provide enough screw-down torques, can conveniently fracture again, twist into two parts.
During use, this anti-demounting bolt is screwed hexagon head 12 through tightening tool tighten, fracture hexagon head 12 or twist into two parts from the portion of twisting into two parts 13 then; Staying oval head 11 continues to be fastened on the screw rod 2; With respect to through an oval head bolton, and oval head 11 inconvenience of the oval head bolt that stays have reached the effect that this anti-demounting bolt can't be dismantled through the screwing tools dismounting; And then avoided the user to adjust this bolt privately and caused potential safety hazard, influence the judgement of accident responsibility.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
