Abstract
The utility model discloses a bolt with an anti-theft function. The bolt with the anti-theft function is wide in application range since the bolt can be used without being matched with corresponding nuts. The bolt comprises a cylindrical bolt head and a screw rod, and the lateral side of the bolt head is provided with a plurality of protruding strips axially parallel to the screw rod. The bolt with the anti-theft function has the advantages that the bolt can be used without being matched with the corresponding nuts but needs to be matched with corresponding special wrenches for use, and thereby the bolt is wide in application range, high in anti-theft coefficient, safe and reliable.
Description
Technical field
The utility model relates to a kind of bolt, refers in particular to a kind of bolt with anti-theft feature.
Background technique
Along with the raising of people's living standard, people's the level of consumption is also more and more higher, and automobile enters in the middle of ordinary people's the family gradually, becomes people's means of transportation.Along with the automobile various places that spread all over the country gradually; the stolen event of automobile tire often can appear; will bring a lot of unnecessary troubles to the car owner in case automobile tire is stolen; cause automobile to become people's burden from people's means of transportation; whether no matter spare tyre arranged; the capital causes automobile not only can not be with conveniently to the people, and has increased virtually people's extra expenses because there is not bolt to cause crying trailer to be dragged away.
Chinese patent notice of authorization number: CN 201679839U, December 22 2010 notice of authorization day, a kind of anti-theft bolt is disclosed, be installed with abnormity nut on the screw thread end of bolt, the abnormity nut outer cover is equipped with sheath, and the sheath bottom is distributed with spring seat, and the spring that is connected with backing pin is arranged on the spring seat, the gland that is connected with sheath is arranged in the sheath, the socket wrench that is fastened with abnormity nut is arranged in the gland.Deficiency of the present utility model is that this anti-theft bolt need to cooperate corresponding nut to use, and has reduced Applicable scope, and complex structure, is not suitable for being applied on the automobile tire.
The model utility content
The utility model is that anti-theft bolt need to cooperate corresponding nut to use and the little deficiency of Applicable scope in the prior art in order to overcome, and providing a kind of does not need to cooperate corresponding nut to use and the large bolt with anti-theft feature of Applicable scope.
To achieve these goals, the utility model is by the following technical solutions:
A kind of bolt with anti-theft feature comprises bolt head and screw rod, and described bolt head is cylindrical body, and described bolt head side is provided with some raised lines parallel with screw axis.
Described bolt head is cylindrical body, described bolt head side is provided with some raised lines parallel with screw axis, because bolt head is cylindrical body so also be cylindrical shape so that be distributed in the formed contour shape of the raised line of bolt head side, so common spanner can't be applicable to this bolt head, so need special-purpose spanner to be suitable for, and the screw rod of this bolt is general common screw, is applicable to general plain nut.Design has satisfied not that needs cooperate corresponding nut to use like this, thereby has reached the large purpose of Applicable scope.
As preferably, described raised line and bolt head are the integral type structure, because raised line and bolt head are integrated, this bolt head becomes the present structure that is similar to stiffening rib by original conventional hexagonal configuration, improved intensity, and alleviated weight, so that it can effectively increase the intensity of bolt head.
As preferably, be the smooth arc transition connection between the described adjacent raised line, the intensity of raised line has effectively been strengthened in design like this, has also further improved the intensity of bolt head simultaneously.
As preferably, be provided with round platform between described bolt head and the screw rod, described round platform stub end connecting bolt head, described round platform microcephaly holds connecting screw rod, described bolt head, round platform and screw rod are the integral type structure, because bolt head, round platform and screw rod are integrated, come the transition bolt head to be connected connection with screw rod by round platform, can effectively increase the intensity of bolt, thus the working life of having improved bolt.
As preferably, be connected for round and smooth arc transition between described round platform and the screw rod, design is on the one hand so that the strength increase that round platform is connected with screw rod like this, and corresponding adversary's part so that this bolt is fitted when assembling more on the other hand is so that assemble tightr.
The beneficial effects of the utility model are: do not need to cooperate corresponding nut to use, need corresponding special key to be used with it, Applicable scope is large, and antitheft coefficient is high, and is safe and reliable.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1. bolt head, 2. screw rod, 3. round platform, 4. raised line.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment one: among the embodiment as described in Figure 1, a kind of bolt with anti-theft feature, comprise bolt head 1 and screw rod 2, described bolt head 1 is cylindrical body, described bolt head 1 side is provided with eight raised lines 4 parallel with screw rod 2 axis, described raised line 4 is evenly distributed on the side of bolt head 1, is that round and smooth arc transition connects between the described adjacent raised line 4, and described raised line 4 is the integral type structure with bolt head 1.Because bolt head 1 is cylindrical body, so also be cylindrical shape so that be distributed in the raised line 4 formed contour shapes of bolt head 1 side, this bolt head becomes the present cylindrical shape structure that is similar to stiffening rib by original conventional hexagonal configuration, improved intensity, and alleviated weight, so common spanner can't be applicable to this bolt head 1, so need special-purpose spanner to be suitable for.Be provided with round platform 3 between described bolt head 1 and the screw rod 2, described round platform 3 stub end connecting bolt heads 2, described round platform 3 microcephalies hold connecting screw rod, and described bolt head 1, round platform 3 and screw rod 2 are the integral type structure, are connected for round and smooth arc transition between described round platform 3 and the screw rod 2.Wherein, the diameter of described round platform 3 stub ends is greater than the diameter of bolt head 1, the diameter of described round platform 3 little head ends is greater than the diameter of screw rod 2, and all adopt round and smooth arc transition to be connected between described bolt head 1 and the round platform 3 and between round platform 3 and the screw rod 2, effectively increase the intensity of whole bolt, improved the working life of this bolt.During implementation, by using the special spanner that matches with it, directly be socketed on the bolt head 1, then fixing bolt head 1 rotates special spanner, namely can realize removing and installing of this bolt.
