Abstract
The utility model discloses and prevent twisting into two parts bolt, including bolt head, first end face of bolt connects screw rod, another end face is provided with central recess, central recess is embedded with an insert with electric conductivity, bolt head is circumferentially distributed several recesses, also includes the plastic part of the plastic material of bolt head described in a parcel.By arranging plastic part and several circumferentially distributed recesses at bolt head, thus improve the conjugation of plastic part and bolt head, the plastic part of plastic material produces when bearing certain twisting load and ruptures, and can solve bolt well operationally can be by the problem of twisting into two parts；May be implemented in again after the plastic part of plastics ruptures uses common tool to be back-outed easily, additionally, when it is installed to storage battery group, shot thereon can be used for detecting electric current.
Description
Technical field
This utility model relates to bolt, is specifically related to prevent twisting into two parts bolt.
Background technology
Traditional bolt is being installed to during storage battery group, easily twists into two parts, and causes follow-up cannot twisting in maintenance process
Go out.
Summary of the invention
This utility model is for problems of the prior art, it is provided that prevent twisting into two parts bolt, by arranging at bolt head
Plastic part and several circumferentially distributed recesses, thus improve the conjugation of plastic part and bolt head, plastic material plastic
Part produces when bearing certain twisting load and ruptures, and can solve bolt well operationally can be by the problem of twisting into two parts；Again can be real
The plastic part of plastics uses common tool to be back-outed after rupturing easily now, additionally, when it is installed to storage battery group, on it
Shot can be used for detect electric current.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: prevent twisting into two parts bolt, including bolt
Head, first end face of bolt connects screw rod, and another end face is provided with central recess, and central recess is embedded with one and has electric conductivity
Insert, bolt head is circumferentially distributed several recesses, also includes plastic material plastic of bolt head described in a parcel
Part.
Described bolt head is hexagonal bolt head.
Described insert is shot.
The beneficial effects of the utility model are: by arranging plastic part and several are circumferentially distributed recessed at bolt head
Mouthful, thus improving the conjugation of plastic part and bolt head, the plastic part of plastic material produces when bearing certain twisting load
Rupturing, can solve bolt well operationally can be by the problem of twisting into two parts；May be implemented in again after the plastic part of plastics ruptures easily
Common tool is used to be back-outed, additionally, when it is installed to storage battery group, shot thereon can be used for detecting electric current.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment, detailed description of the invention of the present utility model is further described.
As shown in Figure 1-2, preventing twisting into two parts bolt, including a hexagonal bolt head 1, first end face of bolt connects screw rod, another
Individual end face is provided with central recess 3, and central recess is embedded with an insert with electric conductivity, and this insert is a shot, bolt
Circumferentially distributed have several recesses 2, also includes the plastic part of the plastic material of bolt head described in a parcel.
During use, it is screwed into, and moment is little, coupling mechanism force strong and is difficult to thread off, and range of application is more extensive, more adapts to market
Demand.Rupture because plastic insulation produces when certain twisting load, bolt can be solved well and operationally (be screwed into
In journey) understand the problem twisted into two parts；May be implemented in again after the plastic part of plastics ruptures uses common tool to back-out easily.
For a person skilled in the art, still the technical scheme described in foregoing embodiments can be repaiied
Changing, or wherein portion of techniques feature carries out equivalent, all within spirit of the present utility model and principle, that is made is any
Amendment, equivalent, improvement etc., within should be included in protection domain of the present utility model.
