Description
Technical field
The utility model relates to a kind of theft-prevention structure of bolt, and the special tool that mounts and dismounts this structure also is provided simultaneously.It is specially adapted to the use of electric power facility or communal facility such as transformer, road sign, guideboard etc.
Background technique
It is the common and general mode of structure that is widely used in mechanical structure, project installation etc. that bolt and nut connects, and installs on some electric power facilities or the communal facility.
With the electric power facility is example, electric power by the electric transmission line of various different electric pressures from the power station through being transported to each power consumer at a distance, the electric power transmission line capital equipment is by potential device, electric pole, compositions such as electric wire, electric pole generally is made up of the backguy of cement electric pole or iron tower and reinforcing thereof, because power circuit is on the way through the each province, the city county, places such as township, be characterized in that line length is wide, the remote mountain area of approach particularly, meagrely-populated place brings certain difficulty for the maintenance of power circuit, wherein a Zui Da difficult problem is exactly easily to be removed as the nut of power circuit fastening piece and the nut of electric power pylon, thereby make equipment such as transformer or iron tower parts stolen, also may cause power circuit to fall bar or iron tower and fall tower, cause the electric power line failure power outage, causing damage and make troubles for the people's life and national wealth, is the problem that people explore always so adopt effective theft-prevention structure on the bolt of installing connects.
At present, the antitheft mode of common bolt have with nut weldering extremely on bolt or connected piece, destroy screw thread and prevent dismounting etc., but these similar modes total all belong to destructive, repair demolition is become, and difficulty, bolt replacement cycle are accelerated, cost increases; And when need changing,, just can't unload replacing because nut is welded extremely, bring difficulty to the power circuit plant maintenance.Chinese patent ZL93210420 discloses a kind of anti-theft bolt, but the bolt processed complex of this structure is difficult for producing in enormous quantities.
The model utility content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of simple in structure and reusable anti-theft bolt and socket wrench specially adapted for it thereof are provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of anti-theft bolt, comprise a bolt and a helmet, described bolt comprises bolt head and has externally threaded screw rod, and is arranged on shoulder between the two, described bolt head periphery is provided with the raised line that can be driven by sleeve, and described shoulder is provided with a circumferential thrust groove; Described helmet comprises the body of a ring and is arranged on the end of this body one end, and the internal diameter of this end is less than the internal diameter of helmet body, and the end of described helmet is embedded in the thrust groove of bolt and both Spielpassung, makes the bolt can rotation in helmet.
Further, described bolt also comprises a blocked part, is arranged between bolt head and the shoulder, and the external diameter of described blocked part is greater than the internal diameter of the end of helmet.
Again further, the periphery of the bolt head of described bolt is provided with 5 raised lines.Described raised line is arranged on the periphery of bolt head with being angle mutually, and angle does not each other wait.
Further, described raised line is semicircular cylinder.
The matching used socket wrench specially adapted for it of a kind of and described anti-theft bolt, comprise a joint and a tube head, described tube head is provided with an endoporus, the wall of described endoporus is provided with the accommodation section, and the external frame that the interior profile that described endoporus and accommodation section are formed and the bolt head of bolt and raised line are formed is complementary.
Further, described accommodation section is 5, be arranged on the wall of endoporus, and angle does not each other wait with being angle mutually.
Again further, described accommodation section is semicircular concave volume.
The beneficial effects of the utility model are mainly reflected in: simple in structure, screw bolt and nut can be reused, and saves cost and reduces the wastage.When dismounting, must use special-purpose instrument, so anti-theft effect is good.

Embodiment
The utility model has disclosed a kind of anti-theft bolt, comprises the bolt 1 and the helmet 2 that cooperatively interact.
As depicted in figs. 1 and 2, bolt 1 comprises bolt head 12 and has externally threaded screw rod 14, and is arranged on shoulder 15 between the two, and described bolt head 12 peripheries are provided with the raised line 13 that can be driven by sleeve, are 5 raised lines 13 in the present embodiment.Described shoulder 15 is provided with a circumferential thrust groove 16.In the present embodiment, described bolt 1 also comprises a blocked part 11, is arranged between bolt head 12 and the shoulder 15, and the external diameter of described blocked part 11 is greater than the external diameter of shoulder 15.
As shown in Figure 3, helmet 2 comprises the body 21 of a ring and is arranged on the end 22 of these body 21 1 ends that the internal diameter of this end 22 is less than the internal diameter of helmet body 21.
As shown in Figure 4, the bolt head 12 of bolt 1 is placed on the inside of helmet 2, and the end 22 of described helmet 2 is embedded in the thrust groove 16 of bolt 1 and both Spielpassung, makes the bolt 1 can rotation in helmet 2.Because the external diameter of blocked part 11 is greater than the internal diameter of the end 22 of helmet 2, and the internal diameter of the end 22 of helmet 2 is again less than the external diameter of bolt shoulder 15, and promptly the end 22 of helmet 2 is embedded in the thrust groove 16 of bolt 1, and bolt 1 can not deviate from from helmet 2.
The utility model adopts the nut of prior art, and promptly its inside is provided with the internal thread that matches with screw rod 14 outside threads.Be placed between the end face of shoulder 15 of nuts and bolt 1 when fastener after, just can use the socket wrench specially adapted for it clamping bolt, and 2 of turn helmets can make helmet 2 rotations, bolt can not play any variation, has reached antitheft effect.
As shown in Figure 5 and Figure 6, the utility model has also disclosed the matching used socket wrench specially adapted for it of a kind of and described anti-theft bolt, comprises a joint 41 and tube 42, and the effect of joint 41 is in order to be connected with socket wrench.Be provided with an endoporus 43 for described 42, the wall of described endoporus is provided with accommodation section 44, and the interior profile that described endoporus 43 and accommodation section 44 are formed is complementary with the external frame that the bolt head 12 of bolt 1 and raised line 13 are formed.
In the utility model, the number of raised line 13 and accommodation section 44 all is 5, and raised line 13 is semicircular cylinder, and accommodation section 44 is semicircular concave volume.Described raised line 13 is arranged on the periphery of bolt head 12 with being angle mutually, and angle does not each other wait.Described accommodation section 44 is arranged on the wall of endoporus 43 with also being angle mutually, and the angle between them equates with angle between each raised line 13.The reason of She Zhiing is like this, and a bolt can only turn with socket wrench specially adapted for it, and is difficult to make the spanner similar to socket wrench specially adapted for it by measuring when user mode, has better played antitheft effect.
The utility model still has multiple concrete mode of execution.For example: the shape of raised line 13 can also be other except semicircle, petal, square or the like; And the number of raised line also is not limited to 5, according to the permission of processing, can be arranged to any number, comprises 1; And the angle between the raised line can most equate to have only several angles not wait, and reduced the difficulty of processing.Same, accommodation section 44 also must be a corresponding setting.
All employings are equal to replacement or equivalent transformation and all technological schemes of forming, all drop within the claimed scope of the utility model.
