Abstract
The utility model discloses a nut, which comprises a conical nut body with a flange. An included angle between the conical surface of the conical nut body and the flange surface is in a range of 40 degrees to 95 degrees; a groove is arranged outside the conical body; and the groove is connected with the conical surface of the conical nut body in a smooth way. The utility model further relates to a dedicated wrench; a conical hole matched with the nut taper is arranged in the dedicated wrench; and a bump meshed with the antitheft nut groove is machined at the inner side of the conical hole. As the conical nut body with the flange only needs to be equipped with a single bolt when mounted, a flat gasket can be saved so as to save the cost and increase the mounting efficiency; as the nut adopts conical nut body and the groove arranged outside the conical nut body is connected with the conical surface in the smooth way, the nut can be only screwed on/off through the dedicated wrench, thereby being convenient to operate; simultaneously, the nut can not be dismounted by a common tool so as to achieve an antitheft effect.
Description
Technical field
The utility model relates to a kind of nut and spanner, particularly a kind of nut and special spanner of dismantling of can preventing.
Background technique
Former express-way guard-rail plates connection generally adopts screw bolt and nut to add the supporting connection of a plain washer.For the ease of loading and unloading the hexagon nut of general employing standard, dismantle stolen with simple tool thereby be easy to stolen molecule like this.When installing, much all adopted express-way guard-rail plates antitheft form based on this present situation.But present anti-theft device or the antitheft form that adopts, structure and complex manufacturing, and also most of product has anti-disassembling function.Though have antitheft effect to a certain extent, mounting process complexity, construction cost are very high, and maintenance the time need be adopted mode mandatory dismantlings such as electric welding cutting, the high and construction inconvenience of expense.
Summary of the invention
The utility model proposes a kind of nut and special spanner in order to solve the deficiency that above-mentioned existing product exists, have safe and convenient to use, sturdy and durable, produce easy characteristics.
Technology contents of the present utility model is to realize like this, a kind of nut comprises the tapered cup nut body of a band circular flange, the conical surface of tapered cup nut body and the angular range of flanged surface are that 40 degree are to 95 degree, the taper arranged outside is fluted, the conical surface of the tightening direction of groove and tapered cup nut body has the 1-8mm gradient, and the disassembly direction of groove smoothly links to each other with the conical surface connecting place of tapered cup nut body.
Described groove, its feature also is: the shape of groove can be oblique triangle, zigzag fashion or irregularly shaped.
The utility model also relates to a kind of special spanner, is provided with the cone shape hole that matches with the nut tapering in the special spanner button, and the inboard conical surface of cone shape hole is processed with the projection that is meshed with the anti-theft nut groove.
Because the utility model is from flanged tapered nut body, only need join single bolt during installation, can save plain cushion, save cost and improved installation efficiency, because nut adopts the groove and the conical surface smooth connection of tapered cup nut body and taper arranged outside, make to use special spanner just can tighten and unload with pine, simple to operate, thus having accomplished simultaneously that general tool can not be dismantled reaches anti-theft effect.
Description of drawings
Fig. 1: nut structure schematic representation of the present utility model.
Fig. 2: special spanner structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are elaborated.
With reference to Fig. 1,2, technology contents of the present utility model is achieved in that a kind of nut comprises the tapered cup nut body 2 of a band circular flange 1, the conical surface of tapered cup nut body 2 and the angular range of flanged surface are that 40 degree are to 95 degree, tapered cup nut body 2 arranged outside fluted 3, the conical surface of the tightening direction of groove 3 and tapered cup nut body 2 has the 1-8mm gradient, and the disassembly direction of groove 3 smoothly links to each other with the conical surface connecting place of tapered cup nut body 2.
Described groove 3, its feature also is: the shape of groove 3 can be oblique triangle, zigzag fashion or irregularly shaped.
The utility model also relates to a kind of special spanner, comprises one handle 4 and button 5, is provided with the cone shape hole 6 that matches with the nut tapering in the button 5, and the cone shape hole 6 inboard conical surfaces are processed with the projection 7 that is meshed with nut groove 3.
When installing, the utility model only need join single bolt, can save plain cushion, tapering and groove shapes corresponding special use corresponding with nut during use used special spanner to clamp to tighten with pine and unloaded, simple to operate, thus having accomplished simultaneously that general tool can not be dismantled reaches anti-theft effect.
