Description

Anti-theft nut and special spanner

Technical field

The utility model relates to a kind of anti-theft nut and special spanner, especially relates to good nut of a kind of theftproof performance and special spanner.

Background technique

In the daily life, the fastening standard bolt and the standard nut of all using of automobile tire, and owing to standard nut very easily is disassembled, so the stolen phenomenon of losing of automobile tire often occurs, this causes very big loss and inconvenience to numerous car owners, and under cover very big dangerous hidden danger.Therefore, be badly in need of the good set screw nut of a kind of theftproof performance, and require cost low, be convenient to promote, and the fixing needs of the tire that can satisfy various vehicles.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of anti-theft nut and special spanner at above-mentioned deficiency of the prior art, and it is simple in structure, uses easy and simple to handlely, and theftproof performance is good, has certain decorative effect, and cost is low, applied range.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-theft nut, it is characterized in that: the nut body that comprises cylindrical shape, the leading portion of described nut body partly is circular shape and the pin-and-hole one that has a plurality of radial direction, and the back segment of described nut body partly has the tapped hole of axial direction.

The quantity of described pin-and-hole one is 3 and evenly distributes around the center line of nut body.

A kind of special spanner that is used for above-mentioned anti-theft nut, it is characterized in that: comprise the handle and the gripping section that are hinged, have the central blind hole of axial direction and a plurality of pin-and-holes two of radial direction on the described gripping section, wherein, the length of described blind hole is not more than the length of matching used anti-theft nut, and the shape of blind hole and the shape of matching used anti-theft nut are complementary, described a plurality of pin-and-hole two communicates around the even distribution of described blind hole and with blind hole, and each pin-and-hole two is corresponding with the position of each pin-and-hole one of supporting use nut and shape is identical.

Described blind hole is a circular shape.

The leading portion of described blind hole partly is that circular shape and back segment partly are cylindrical shape.

The utility model compared with prior art has the following advantages: the utility model anti-theft nut is simple in structure, cost is low, because of nut body is a cylindrical shape, and leading portion is partly for having the circular shape of a plurality of pin-and-holes one, so can only use special spanner just can screw or unload anti-theft nut, therefore theftproof performance is good, and has certain decorative effect; When using the utility model special spanner to remove and install anti-theft nut, clamping is reliable, and is easy to operate; Have on the anti-theft nut and be used for the universal standard tapped hole that matches with the automobile tire bolt, therefore can be as general fastening piece extensive use and automobile tire fastening, so using scope is wide.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment

As shown in Figure 1, the utility model anti-theft nut comprises the nut body 2 of cylindrical shape, the leading portion of nut body 2 partly is circular shape and the pin-and-hole 1 that has a plurality of radial direction, the back segment of nut body 2 partly has the tapped hole 3 of axial direction, and the screw thread on the tapped hole 3 is a universal standard screw thread.In the present embodiment, the quantity of pin-and-hole 1 is 3 and evenly distributes around the center line of nut body 2.

As shown in Figures 2 and 3, the utility model special spanner comprises handle 4 and the gripping section 5 that is articulated and connected, have the central blind hole 7 of axial direction and a plurality of pin-and-holes 26 of radial direction on the gripping section 5, wherein, for guaranteeing the matching property between gripping section 5 and the matching used anti-theft nut, the length of blind hole 7 is not more than the length of matching used anti-theft nut, and the shape of blind hole 7 with the leading portion shape of matching used anti-theft nut be complementary, each pin-and-hole 26 evenly distributes and all communicates with blind hole 7 around blind hole 7, each pin-and-hole 26 with on the matching used nut body 2 position of each pin-and-hole 1 corresponding and shape is identical.

As shown in Figure 2, in first kind of mode of execution of the utility model special spanner, blind hole 7 is a circular shape, and promptly when using this special spanner to turn anti-theft nut, blind hole 7 partly cooperatively interacts with the circular shape of nut body 2.

As shown in Figure 3, in second kind of mode of execution of the utility model special spanner, for making the clamping between gripping section 5 and the nut body 2 more reliable, blind hole 7 leading portions partly are that circular shape and back segment partly are cylindrical shape.

The utility model anti-theft nut is a cylindrical shape, if use general spanner then to be difficult for clamping, or clamps not strongly and leans on, and slides easily, so must use special spanner when using this anti-theft nut, makes theftproof performance good.When using this anti-theft nut, the gripping section 5 of special spanner is enclosed within on the nut body 2, re-using a plurality of bearing pins interts respectively in corresponding pin-and-hole 26 and pin-and-hole 1 with the fixing relative position of special spanner and anti-theft nut, make clamping firm, like this, handle with sleeve 4 can screw or unload anti-theft nut.

The utility model anti-theft nut is mainly used in the fastening of automobile tire, can prevent effectively that tire is stolen, safeguarded car owner's interests, moreover the leading portion of the circular shape of anti-theft nut partly has certain decorative effect.The utility model anti-theft nut also can be used as general fastener application in other field.

The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
