Abstract
The invention discloses an inner-hexagonal anti-loosening bolt. The inner-hexagonal anti-loosening bolt comprises a circular bolt head, a screw rod and a thread, wherein a hexagonal groove is formed above the bolt head; three anti-skid bar which are connected diagonally are arranged in the hexagonal groove; the hexagonal groove is partitioned into six triangular spaces; anti-skid saw teeth are arranged below the bolt head; one end of the screw rod is vertically connected with the lower side of the bolt head; the thread is formed at the other end of the screw rod; the lower half part of the thread is coated with an anaerobic adhesive. According to the inner-hexagonal anti-loosening bolt, the anti-skid saw teeth and the anaerobic adhesive have very good anti-loosening effects, and anti-skid bars arranged in the inner-hexagonal groove of the bolt head have good anti-detaching effects. The inner-hexagonal anti-loosening bolt has the advantages of simple structure, convenience in use, safety, reliability and long service life.
Description
Technical field
The invention belongs to fence Component technical field, be specifically related to a kind of interior hexagonal check bolt.
Background technique
Fence be usually used in boundary's enclosure from or Region dividing, zone protection, its purposes is very extensive, be widely used in industry, agricultural, pastoral farming, forestry, expressway, railway, national defence, airport, harbour, municipal administration guardrail, greening, grassland, the isolation in the various place such as orchard and protection, present is firm to the requirement of fence, durable in use, except structure and material wants science, bolt used also requires locking, can not loosen when there being vibrations, at will can not be dismantled by stranger, past market there is the chek bolt of various ways, but all in various degree there is various problem, drastically influence quality and the working life of fence.
Summary of the invention
For solving the problem, the invention discloses a kind of in hexagonal check bolt, locking, tamper is effective, safe and reliable, long service life.
For achieving the above object, technological scheme of the present invention is as follows:
Hexagonal check bolt in a kind of, it is characterized in that: comprise circular bolt head, screw rod, screw thread, the top of described bolt head is provided with hexagonal groove, be provided with 3 tread plates in described hexagonal groove and connect diagonal angle, hexagonal groove is separated into 6 triangle spaces, the below of bolt head is provided with anti-skidding sawtooth, and described screw rod one end is connected with vertical immediately below bolt head, described screw thread is arranged on the other end of screw rod, scribbles anaerobic adhesive in the Lower Half of screw thread.
As a modification of the present invention, described bolt head is semicircle.
As a modification of the present invention, the height of described 3 tread plates is lower than the height of hexagonal groove.
As a modification of the present invention, described 3 tread plates wherein one be main tread plate, the thickness of described main tread plate be the 2-3 of other two tread plates doubly.
As a modification of the present invention, other two tread plates described and hexagonal groove joint are provided with stiffening rib.
As a modification of the present invention, the thickness of described stiffening rib is identical with the thickness of main tread plate.
As a modification of the present invention, described stiffening rib and other two tread plate joints are circular arc.
As a modification of the present invention, the zinc-plated or copper facing of described bolt head, screw rod, thread surface.
The invention has the beneficial effects as follows:
Hexagonal check bolt in one of the present invention, anti-skidding sawtooth and anaerobic adhesive can have good anti-loosing effect, are provided with tread plate tamper effective in the hexagonal groove of bolt head, and structure is simple, easy to use, safe and reliable, long service life.
Accompanying drawing explanation
Fig. 1 is the top schematic diagram of bolt head of the present invention.
Fig. 2 is plan view of the present invention.
Reference numerals list:
1, bolt head, 2, hexagonal groove, 3, main tread plate, 4, tread plate, 5, triangle space, 6, anti-skidding sawtooth, 7, screw rod, 8, screw thread, 9, anaerobic adhesive, 10, stiffening rib, 11, circular arc.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, following embodiment should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometrical center respectively.
As shown in the figure, hexagonal check bolt in one of the present invention, comprise circular bolt head 1, screw rod 7, screw thread 8, the top of described bolt head 1 is provided with hexagonal groove 2, is provided with 3 tread plates 4 and connects diagonal angle, hexagonal groove 2 is separated into 6 triangle spaces 5 in described hexagonal groove 2, the below of bolt head 1 is provided with anti-skidding sawtooth 6, described screw rod 7 one end is connected with vertical immediately below bolt head 1, and described screw thread 8 is arranged on the other end of screw rod 7, scribbles anaerobic adhesive 9 in the Lower Half of screw thread 8.
Hexagonal check bolt in one of the present invention, anti-skidding sawtooth 6 and anaerobic adhesive 9 by bolton, can have good anti-loosing effect; Bolt head 1 is circular, and spanner cannot be removed, and is provided with tread plate 4 in the hexagonal groove 2 of bolt head, and unless there are special instrument, other people cannot set about at all, and tamper is effective, and structure of the present invention is simple, easy to use, safe and reliable, long service life.
In order to promote tamper effect, described bolt head 1 is designed to semicircle by the present invention, reduces the surface of contact of bolt head 1 side, with instruments such as spanners by bolt integral demounting, Security cannot be improved, increases the service life, and be contained on fence elegant in appearance, have no lofty sense.
The height of 3 tread plates of the present invention is lower than the height of hexagonal groove 2, and 3 tread plates are arranged in hexagonal groove 2 and reduce destroyed possibility, can also improve rustless property.
In order to ensure when maintaining, bolt is for convenience detach, the present invention by described 3 tread plates wherein one be set to main tread plate 3, the thickness of described main tread plate 3 is 2-3 times of other two tread plates 4, the thickness of general tread plate is about 1mm, the thickness of main tread plate 3 is about 2-3mm, during dismounting, spanner major part rotary pressure born by main tread plate 3, ensure that tread plate is in installation, can not damage during dismounting, for other two tread plates, the present invention is provided with stiffening rib 10 at other two tread plates described and hexagonal groove 2 joint, the thickness of described stiffening rib 10 is identical with the thickness of main tread plate 3, help to share pressure when spanner rotates, ensure that tread plate Anti-dismounting structure is complete, reduce the possibility of artificial damage, described stiffening rib 10 is circular arc 11 with other two tread plate joints, transitions smooth, uniform force.
