Abstract
The utility model discloses an anti-penetration nut. The anti-penetration nut is embedded in a screw stud for locking a screw. The anti-penetration nut comprises a locking part and an anti-penetration part, wherein the inside of the locking part is hollow column-shaped, threads are formed in the locking part, and threads in the locking part are matched with threads of the screw; through holes which run through a body are formed in the anti-penetration part, and one end of the anti-penetration part is connected with the locking part while the other end is sealed through a pedestal. According to the anti-penetration nut, the bottom is sealed, and therefore, in assembling, if the user misuses a longer screw, the pedestal can prop against the screw to prevent the screw from locking, and then the screw cannot lock at the right position, and accordingly the screw is avoided from continuing to lock, and the phenomenon that the screw penetrates a plastic piece is avoided.
Description
[technical field]
The utility model relates to a kind of five metals and connects workpiece, relates in particular to a kind of anti-lock nut of wearing.
[background technique]
The shell of the 3C Product of moulding at present, major part is all by plastic rubber shaping, and to make plastic molded product just inevitably can use and plant nail, be about to nut heeling-in in plastic parts, thereby screw can be locked together the shell matching easily by this nut.
The process of general locking screw is, first by after nut heating, utilize its heat conduction principle to carry out indirect heating screw column, thereby make to have after the screw column melting of plastic cement material can with the gear phase interlock of this screw periphery, and then reach the object of nut being implanted to screw column, finally by with the suitable screw locking of this nut in the screw of this nut, thereby reach the object of completed knocked down products shell.
Yet, what current use was held by factory is all general plain nut, it is the structure of through hole, when the screw nut hot melting of this through-hole structure is to after in plastic parts, assembler, when completed knocked down products shell, if misapplied longer screw, therefore likely can be worn this plastic parts top in the process locking, thereby can not guarantee the quality of product, will reduce greatly working efficiency simultaneously.
In view of this, be in fact necessary to provide a kind of and prevent that screwed lock from wearing the nut of plastic parts, to solve, above-mentionedly the phenomenon that lock is worn plastic parts easily occurs when locking screw because of plain nut.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of anti-lock nut of wearing, to address the above problem.
In order to achieve the above object, the anti-lock nut of wearing that the utility model provides, it is implanted in screw column for locking screw, and the described anti-lock nut of wearing comprises:
Locking section, its inside is hollow cylindrical, and the inside of described locking section has screw thread, the screw thread of inside, described locking section and the screw-thread fit of described screw;
Prevent wearing portion, its inside has the through hole that runs through body, and described anti-one end of wearing portion is connected with described locking section, and the described anti-the other end of wearing portion passes through base seal.
Preferably, the outside of described locking section also has screw thread, and the screw thread of outside, described locking section is used for and the interlock of described screw column hot melt.
Preferably, described base and described anti-the other end adaptation of wearing portion.
Compared to prior art, the anti-lock nut of wearing of the utility model passes through sealed bottom, thereby in the process of assembling, if misapplied longer screw, described base can prop up this screw does not allow it continue to lock, just there will be screwed lock situation not in place, thereby will can not allow screwed lock go down always, avoided the phenomenon that plastic parts top is worn.
[accompanying drawing explanation]
Fig. 1 illustrates the structural representation of wearing nut for the utility model is anti-lock.
Fig. 2 illustrates another structural representation of wearing nut for the utility model is anti-lock.
[embodiment]
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
In order to achieve the above object, refer to Fig. 1 and Fig. 2 illustrates, the anti-lock nut 100 of wearing that the utility model provides, it is implanted in screw column for locking screw, and the described anti-lock nut 100 of wearing comprises:
Locking section 110, its inside is hollow cylindrical, and the inside of described locking section 110 has screw thread 111, the screw thread 111 of 110 inside, described locking section and the screw-thread fit of described screw;
Prevent wearing portion 120, its inside has the through hole that runs through body, and described anti-one end of wearing portion 120 is connected with described locking section 110, and the described anti-the other end of wearing portion 120 seals by base 121.
Wherein, the outside of described locking section 110 also has screw thread 112, the screw thread 112 of 110 outsides, described locking section for the interlock of described screw column hot melt.
Wherein, described base 121 and described anti-the other end adaptation of wearing portion 120.
The anti-lock nut 100 of wearing of the utility model passes through sealed bottom, thereby in the process of assembling, if assembler has been misapplied longer screw, described base 121 can prop up this screw does not allow it continue to lock, just there will be screwed lock situation not in place, thereby will can not allow screwed lock go down always, avoid the phenomenon that plastic parts top is worn.
The utility model is anti-lock wears the quality that nut 100 has effectively guaranteed product, has reduced repair rate, thereby has increased work efficiency greatly.
It is to be noted; the utility model is not limited to above-mentioned mode of execution; any simple modification, equivalent variations and modification that any those skilled in the art do above-described embodiment based on technical solutions of the utility model, all fall into protection domain of the present utility model.
