Abstract
The utility model discloses an anti-separation component for a screw. The component comprises a blocking piece, the screw, an upper box body and an elastic O-shaped ring, wherein the screw sequentially penetrates through the blocking piece, the elastic O-shaped ring and the upper box body; the blocking piece is in interference fit with the upper box body; the internal diameter of the elastic O-shaped ring is less than the large diameter of the screw. According to the component, a mounting screw of a huff joint box can be prevented from being separated; the screw penetrates through the upper box body, and is screwed on a thread of a lower box body to be locked; if the box is required to be opened, the screw is unscrewed, and only can idly rotate and cannot fall off the upper box body after leaving a nut, so that time for looking for and mounting the screw during subsequent locking is reduced.
Description
Technical field
The utility model relates to a kind of anti-drop assembly of Hafu type connector box mounting screw.
Background technique
The mounting screw of the upper and lower box body of present Hafu type connector box does not on the market have anti-drop assembly.Before use, need to open upper cartridge body, and screw very easily comes off.
Summary of the invention
The purpose of this utility model is to provide a kind of screw anti-drop assembly, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A screw anti-drop assembly, comprises catch, screw, upper cartridge body, elasticity O type circle, and described screw passes catch, elasticity O type circle and upper cartridge body successively, catch and upper cartridge body interference fit, and the inner diameter of elasticity O type circle is less than the large footpath of screw.
As further program of the utility model: described elasticity O type circle is silica gel O type circle.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can prevent the mounting screw anticreep of Hafu type connector box; Screw, through upper cartridge body, is screwed on the screw thread of lower box body to locking; As needed, open, unclamp screw, screw leaves after nut, can only dally, and can not drop out from upper cartridge body, the time of searching and mounting screw while having reduced follow-up locking.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of screw anti-drop assembly.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, in the utility model embodiment, a kind of screw anti-drop assembly, comprise catch 1, screw 2, upper cartridge body 3, elasticity O type circle 4, described screw 2 is successively through catch 1, elasticity O type circle 4 and upper cartridge body 3, catch 1 and upper cartridge body 3 interference fit, the inner diameter of elasticity O type circle 4 is less than the large footpath of screw 2.Described elasticity O type circle 4 is silica gel O type circle.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any reference character in claim should be considered as limiting related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme in each embodiment also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
