Abstract
The utility model belongs to the field of fastening pieces, and discloses an anti-theft bolt. The anti-theft bolt comprises a screw rod and a round screw head, wherein the screw rod is arranged at the lower end of the round screw head. The anti-theft bolt is characterized in that a special wrench insertion hole which is perpendicular to the upper end surface of the round screw head and penetrates through the round screw head is formed in the round screw head; a threaded hole perpendicular to the upper end surface of the round screw head is formed in the center of a circle of the upper end surface of the round screw head; and a small screw rod at the lower end of a thread cap is matched with the threaded hole. The anti-theft bolt has the benefits that the structure of the bolt is improved, and the special wrench insertion hole and the thread cap are arranged on the screw head; when the anti-theft bolt is screwed or unscrewed, the thread cap on the round screw head is screwed off firstly, then a special wrench of the anti-theft bolt is aligned to the special wrench insertion hole, and the anti-theft bolt can be screwed or unscrewed; therefore, the anti-theft bolt has lower possibility of being stolen when used for mounting and fixing public facilities such as outdoor electrical equipment, communication devices and the like.
Description
Technical field
The utility model relates to a kind of fastener areas, specifically is meant to relate to a kind of anti-theft 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: installing and fixing outdoor power equipment, during easily stolen communal facility such as communications equipment, use common standard piece bolt to carry out fastening will being easy to and stolen, lack a kind of antitheft nonstandard clamping bolt by pine.
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 anti-theft bolt, solve existing bolt when installing and fixing stolen easily communal facility such as outdoor power equipment, communications equipment, use common standard piece bolt to carry out fastening will being easy to and stolen, lack a kind of problem of antitheft nonstandard clamping bolt by pine.
The purpose of this utility model is to realize by following technical solution:
The technical solution of the utility model is: a kind of anti-theft bolt, comprise described screw rod and circle spiral shell head, described screw rod is arranged at round spiral shell head lower end, described round spiral shell head is provided with perpendicular to circle spiral shell head upper-end surface and runs through the special spanner jack of round spiral shell head, the circle centre position of described round spiral shell head upper-end surface is provided with the tapped hole perpendicular to circle spiral shell head upper-end surface, and the small screw of described threaded cap lower end matches with tapped hole.
Preferably, described special spanner jack is six and is distributed on the round spiral shell head.
Preferably, the diameter of described round spiral shell head equals the diameter of threaded cap.
Preferably, the equal diameters of described six special spanner jacks, and special spanner jack diameter is 1/8th of circle spiral shell head diameter.
The utility model compared with prior art has following beneficial effect:
The utility model improves on the structure of bolt, be provided with special spanner jack and threaded cap at Luo Toushang, when tightening or unscrewing this anti-theft bolt, the threaded cap that to justify on the spiral shell head screws off earlier, again the special spanner of this anti-theft bolt is aimed at the special spanner jack and just can tighten or unscrew this anti-theft bolt, it is stolen to make that this anti-theft bolt is not easy when installing and fixing communal facility such as outdoor power equipment, communications equipment.
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 anti-theft bolt of the utility model.
The number in the figure explanation:
The 1-screw rod, 2-circle spiral shell head, 3-threaded cap, 4-special spanner jack, 5-tapped hole, 6-small screw.
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 anti-theft bolt, comprise described screw rod 1 and circle spiral shell head 2, described screw rod 1 is arranged at round spiral shell head 2 lower ends, described round spiral shell head 2 is provided with perpendicular to circle spiral shell head 2 upper-end surfaces and runs through the special spanner jack 4 of round spiral shell head 2, the circle centre position of described round spiral shell head 2 upper-end surfaces is provided with the tapped hole 5 perpendicular to circle spiral shell head 2 upper-end surfaces, and the small screw 6 of described threaded cap 3 lower ends matches with tapped hole 5.
Further, described special spanner jack 4 is six and is distributed on the round spiral shell head 2.
Further, the diameter of described round spiral shell head 2 equals the diameter of threaded cap 3.
Further, the equal diameters of described six special spanner jacks 4, and special spanner jack 4 diameters are 1/8th of circle spiral shell head 2 diameters.
When tightening or unscrewing this anti-theft bolt, the threaded cap 3 that to justify earlier on the spiral shell head 2 screws off, again the special spanner of this anti-theft bolt is aimed at special spanner jack 4 and just can tighten or unscrew this anti-theft bolt, it is stolen to make that this anti-theft bolt is not easy when installing and fixing communal facility such as outdoor power equipment, communications equipment.
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.
