To another component or it may be simultaneously present component placed in the middle.When a component is considered as " being set to " another component, it
It can be and be set up directly on another component or may be simultaneously present component placed in the middle.Term as used herein is " vertical
", " horizontal ", "left", "right" and similar statement for illustrative purposes only.
Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model
The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein includes
Any and all combinations of one or more related listed items.
It please refers to Fig.1 to Fig.3, a kind of anti-theft bolt, including stud 2 and head 1, stud 2 and head 1 in the present embodiment
For separate structure, the shape on head 1 is not limited, the outer hexagon shape structure cooperated with open-end wrench is may be designed as, can design
For end band hexagonal hole, the structure cooperated with allen wrench can also be equipped with cross recess for top, cooperate with Phillips screwdriver
Structure, because being conventional fastener standard design, this embodiment is not repeated.
One end of bolt headward 1 in the present embodiment is equipped with several connection through-holes 21, it is contemplated that the structure of stud 2 is strong
Degree, the present embodiment is designed as three connection through-holes 21, and is circumferentially uniformly distributed centered on the central axis of stud 2, makes head 1
On connecting column 11, after insertion connects through-hole 21, stud 2 and head 1 mutually force, uniform force.And each connection through-hole 21
Cross section be polygonized structure (the present embodiment is preferably that cross section is triangular structure, the characteristics of using triangular structure,
Guarantee the stable structure of connection through-hole 21), increase the difficulty that criminal finds the tool of embeddable connection through-hole 21, further
Improve the safety of the present embodiment.
In addition, the present embodiment is equipped with reset spring 22 in each connection through-hole 21, and one end of each reset spring 22 is equal
It being connected with the bottom for connecting through-hole 21, one end of each 22 opposing headers 1 of reset spring is respectively connected with baffle 23, meanwhile, each baffle
23 cross section is identical as the connection cross section of through-hole 21 where each baffle 23.Head 1 and stud 2 are divided in staff
From when, baffle 23 can be bounced using the effect of reset spring 22, block connection through-hole 21, make to connect through-hole 21 be not easy it is non-
Method molecule is discovered, is found, the concealment of the present embodiment is improved.It, only need to be by each connecting column 11 if you need to which head 1 to be connect with stud 2
It is directed at corresponding connection through-hole 21 to be inserted into, baffle 23 can be moved to the depth of connection through-hole 21 because of the compression of compressed spring
Place, it is easy to operate, quick.
In order to make bonding strength and fastening force of the present embodiment after unloading head portion 1, by further designing, improving,
Side 24 is prolonged equipped with circular ring shape in one end of stud 2 headward 1, using the effect for prolonging the replacement conventional bolt head 1 of side 24, in spiral shell
After column 2 is tightened, prolong the surface that side 24 tightly contradicts installations and facilities.Prolong side 24 outer circumference surface be arcuate structure, avoid with respectively
Conventional, general utility tool cooperation.
In order to reinforce the bonding strength on head 1 and stud 2 when not needing disassembly head 1, the present embodiment is in 2 direction of stud
The one end on head 1 is equipped with the groove 25 for being embedded in for head 1, and (groove 25 may be designed to the inner wall of hexagonal structure, with head
1 outer circumference surface is chimeric, shares connecting column 11, transmitting torque), and punched on the top on head 1, wear one piece of fixed screw
3, the threaded connection on head 1 and stud 2 is passed through by fixed screw 3, head 1 is fixed on stud 2, to reinforce head 1
With the bonding strength of stud 2.
Meanwhile the Design of Screw Thread of fixed screw 3 is reverse thread, after stud 2 is tightened, when staff needs to unload
When head 1, the direction for unscrewing fixing bolt is consistent with the direction for tightening stud 2, therefore not will cause bolt and installations and facilities company
What is connect loosens.
The present embodiment it is antitheft easy to operate, through-hole 21 or need to only be pulled out when required by connecting column 11 is embedded in connection
The mode for connecting through-hole 21 out achievees the purpose that load and unload head 1.For save the cost, can also be cooperated by a head 1 more
The mode of a stud 2.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
