Abstract
The utility model discloses a screw capable of avoiding being loosened accidently. The screw capable of avoiding being loosened accidently comprises a screw (1) provided with a head part and a threaded rod part, wherein a regular triangular concave hole (2) for a tool to screw up or screw down the screw is formed on the top of the head part of the screw (1); and the threaded rod part of the screw (1) has a self-tapping screw structure, or a standard screw rod structure matched with a threaded hole. The screw capable of avoiding being loosened has the advantages of capability of avoiding being screwed up by an ordinary screwdriver, convenience for use, difficult breakage of the regular triangular concave hole in the using process and the like.
Description
Technical field
The utility model relates to a kind of can preventing and is belonged to the screw fastener technical field by the loosening screw of accident.
Background technique
At present, screw of the prior art often is manufactured with at its head and is used for instrument and opens or tighten in-line or the criss-cross groove that screw is used, and the screw of this structure is very suitable for traditional bottle opener instrument and opens or tighten.When some does not hope by the component of general ordinary person's unlatching when the screw connection of adopting existing this structure; Because it is easy to open through common bottle opener instrument; Therefore it is easy to by common personnel's fault open, thereby causes some unnecessary loss.Therefore existing screw still can not satisfy the use of some special occasions.
Summary of the invention
The purpose of the utility model is: provide a kind of easy to use, and can prevent to be opened by mistake can preventing of opening by the loosening screw of accident, to overcome the deficiency of existing technology by common bottle opener instrument.
The utility model is to constitute like this: a kind of can the preventing of the utility model comprised the screw that is provided with head and thread rod part by the loosening screw of accident, is provided with the shrinkage pool that is used for the instrument unlatching or tightens the equilateral triangle that screw uses at the apical head of screw.
The thread rod part of above-mentioned screw is the tapping screw structure or is the master screw structure that is used with tapped hole.
Owing to adopted technique scheme; The shrinkage pool that in-line that screw uses or criss-cross groove are changed system into equilateral triangle is opened or tightened to the utility model with traditional instrument that is used for; So in use, can only use sectional shape to open or tighten the utility model as the special screwdriver of equilateral triangle.Thereby prevented that effectively other people unrelated person from adopting common bottle opener instrument to open the device that adopts the utility model locking.Therefore, the utility model compared with prior art, the utility model not only has and can prevent to be opened by mistake the advantage that opens by common bottle opener instrument, but also has advantages such as shrinkage pool easy to use, its equilateral triangle in use is difficult for being destroyed.

Schematic representation when Fig. 1 is the tapping screw structure for the thread rod part of the utility model screw;
Fig. 2 is the schematic representation during for the master screw structure that is used with tapped hole for the thread rod part of the utility model screw;
Fig. 3 is the plan structure schematic representation of Fig. 1 or Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to say in detail.
The embodiment of the utility model: a kind of can prevent by the loosening screw of accident the time what make the utility model; Can be made into the screw 1 that is provided with head and thread rod part, can the threaded stem of screw 1 partly be made as traditional tapping screw structure (as shown in Figure 1) or be made into the traditional standard screw-rod structure (as shown in Figure 3) that can be used with the traditional standard tapped hole; During making, adopt the mode of punching press to produce to be used for instrument to open or tighten the shrinkage pool 2 (like Fig. 2 or shown in Figure 3) of equilateral triangle that screw uses at the apical head of screw 1.
Claims (2)
1. one kind can prevent to be comprised the screw (1) that is provided with head and thread rod part by the loosening screw of accident, it is characterized in that: be provided with the shrinkage pool (2) that is used for the instrument unlatching or tightens the equilateral triangle that screw uses at the apical head of screw (1).
2. according to claim 1 can preventing is characterized in that by the loosening screw of accident: the thread rod part of screw (1) is the tapping screw structure or is the master screw structure that is used with tapped hole.
