Abstract
The utility model belongs to the field of fasteners and discloses a quadrangular fixing bolt. The quadrangular fixing bolt comprises a quadrangular screw head and a screw rod, wherein the quadrangular screw head is arranged at the upper end of the screw rod; a locking thread through hole perpendicular to the upper end surface of the quadrangular screw head is formed in the quadrangular screw head; and a matched locking screw is arranged on the locking thread through hole. The quadrangular fixing bolt disclosed by the utility model has the beneficial effects that the locking thread through hole is formed in the quadrangular screw head of the bolt and the matched locking screw is arranged on the locking thread through hole, so that when the quadrangular fixing bolt is connected to and arranged on a matched screw cap or an object, the actions of preventing retracting and loosening can be achieved by only screwing down the locking screw on the quadrangular screw head to generate the resistance.
Description
Technical field
The utility model relates to a kind of fastener areas, specifically refers to relate to a kind of Corner Strapped bolt.
Background technique
Bolt as a kind of installation and fixedly the fastening piece of section bar be extensive use of by people, the kind that uses bolt in the existing assembly process is a lot, but be the structural design that adopts the bolt standard piece in general mostly, that is to say that each bolt in the section bar installation all is to use with the form of standard piece, in real life, the design that it is found that this bolt standard piece has the following disadvantages: bolt is on being connected to the nut that matches or on the article time, because of the contact surface of bolt more smooth, remote along with the time, bolt are loosening even come off easily.
Summary of the invention
For shortcoming and the deficiency that overcomes background technique, the purpose of this utility model is to provide a kind of Corner Strapped bolt, solve existing bolt on being connected to the nut that matches or on the article time, because of the contact surface of bolt more smooth, remote along with the time, bolt be the loosening even problem that comes off easily.
The purpose of this utility model is to realize by following technical solution:
The technical solution of the utility model is: a kind of Corner Strapped bolt, comprise described four jiaos of spiral shell heads and screw rod, described four jiaos of spiral shell heads are arranged at the screw rod upper end, described four jiaos of spiral shell heads are provided with the locking screw through hole perpendicular to four jiaos of spiral shell head upper-end surfaces, and described locking screw through hole is provided with the locking nut that matches.
Preferably, the length of described locking nut is greater than the length of locking screw through hole.
Preferably, described locking nut is that screw rod and an end have a word groove.
The utility model compared with prior art has following beneficial effect:
The utility model is owing to four jiaos of locking nuts that the spiral shell head is provided with the locking screw through hole and matches at bolt, this Corner Strapped bolt is connected on the nut that matches or on the article time, produces resistances and can play anti-back and loosen effect as long as tighten four jiaos of locking nuts on the spiral shell head.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the structural representation of a kind of Corner Strapped bolt of the utility model.
The number in the figure explanation:
Four jiaos of spiral shell heads of 1-, 2-screw rod, 3-locking nut, 4-locking screw through hole.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
Contrast accompanying drawing 1 as can be known, a kind of Corner Strapped bolt, comprise described four jiaos of spiral shell heads 1 and screw rod 2, described four jiaos of spiral shell heads 1 are arranged at screw rod 2 upper ends, described four jiaos of spiral shell heads 1 are provided with the locking screw through hole 4 perpendicular to four jiaos of spiral shell head 1 upper-end surfaces, and described locking screw through hole 4 is provided with the locking nut 3 that matches.
Further, the length of described locking nut 3 is greater than the length of locking screw through hole 4.
Further, described locking nut 3 has a word groove for screw rod and an end.
This Corner Strapped bolt is connected on the nut that matches or on the article time, produces resistances and can play anti-back and loosen effect as long as tighten four jiaos of locking nuts 3 on the spiral shell head 1.
Need to prove; below schematically the utility model and mode of execution thereof are described; this description does not have restricted; described in the accompanying drawing also is one of mode of execution of the present utility model; practical structure is not limited thereto; if generally speaking those of ordinary skill in the art is enlightened by it; under the situation that does not break away from the utility model creation aim; without creationary mode of structure and the embodiment who knows each other with this technological scheme that design, all should belong within the protection domain of the present utility model.
