Abstract
The utility model relates to an environment-friendly cylindrical pin type anti-dismantling and anti-theft nut, and mainly solves the problems that an existing locking nut is poor in anti-dismantling and anti-theft function and can pollute the environment. The environment-friendly cylindrical pin type anti-dismantling and anti-theft nut is characterized in that at least two arc-shaped wedge grooves (2) are axially formed in the inner wall of a nut body (1), an elastic block (3) is pasted on the inner wall of each arc-shaped wedge groove (2), and a cylindrical pin (4) is pasted on the outer side face of each elastic block (3). The environment-friendly cylindrical pin type anti-dismantling and anti-theft nut has the advantages of being good in anti-dismantling and anti-theft function, friendly to the environment and the like.
Description
Technical field
The utility model relates to a kind of axial lock compact form fastening piece, is the anti-anti-theft nut that unloads of a kind of environment protection type straight pin specifically.
Background technique
Nut is a kind of widely used fastening piece that matches with bolt, as long as screwing in the bolt that matches with it just can clamp clamped thing, very easy to use, but in use, particularly in the open air under the unserviced situation, sometimes because artificially its dismounting being produced unsafe factor, even have an accident.Axial locking anti-theft fastening piece commonly used generally adopts single steel ball directly to contact, because its frictional force is little, phenomenon such as can occur skidding or move axially when falling to twist makes anti-reliability of unloading anti-theft feature reduce greatly.And some locking nut adopts interim plug sleeve that steel ball or pin are fixed in the wedge groove, after interim plug sleeve withdraws from use it is abandoned, if a large amount of the use, the interim plug sleeve of abandoning then pollutes the environment.
Summary of the invention
Existing locking nut is anti-to unload that anti-theft feature is poor, the deficiency of befouling environment in order to overcome, and the utility model provides a kind of environment protection type straight pin the anti-anti-theft nut that unloads, and this environment protection type straight pin is anti-to be unloaded anti-theft nut and have and anti-ly unload that anti-theft feature is good, the characteristics of environmental protection.
The technical solution of the utility model is: at least two arc wedge grooves are axially arranged on the described nut inner wall, be pasted with elastomer block on the described arc wedge groove inwall, the outer side surface of elastomer block is pasted with straight pin.
Up and down both sides are all in nut inside for described arc wedge groove, and the angle of arc wedge bottom land limit and nut axial direction is less than 90o.
The cross section of described elastomer block is trapezoidal or triangle.
Described straight pin is stainless steel material, and there is decorative pattern on its surface.
The utlity model has following beneficial effect: owing to take such scheme, the nut inner hole wall is provided with arc wedge groove, arc wedge groove is built-in with elastomer block and straight pin, because elastomer block has certain elasticity, when the dismounting nut, under the effect of elastomer block, straight pin is all the time in the angle of the screw thread of curve bath and bolt handing-over, with nut check, under the situation of not destroying nut, it can't be dismantled like this, realized the anti-anti-theft feature that unloads reliably.Elastomer block and straight pin stick in the curve bath simultaneously, can not cancel interim plug sleeve by coming off in the groove, thereby avoid plug sleeve befouling environment in use, reach environmental requirement.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
To shown in Figure 4, a kind of environment protection type straight pin is anti-to unload anti-theft nut, comprises nut 1 by Fig. 1, and described nut 1 profile is hexagon, and namely identical with common hexagonal locking nut, instrument that need not be special is easy to use so when mounted.One side end face of nut 1 can be provided with boss 6, and the edge of boss is arc round angle, in use, and outside boss 6 one side direction.At least two arc wedge grooves 2 are axially arranged on described nut 1 inwall, and the quantity of arc wedge groove 2 also can be uniformly distributed along the circumference for three.Be pasted with elastomer block 3 on described arc wedge groove 2 inwalls, the surface of elastomer block 3 is pasted with straight pin 4.Described elastomer block 3 can be objects such as foam, plastics, plastic cement, rubber, nonwovens, can also be have magnetic or band paste object or magnetic patch and spring etc.There is decorative pattern on the surface of straight pin 4, can be straight burr, twill or reticulate pattern, and its material is stainless steel, the wedge height.The diameter of straight pin 4 can be decided according to the size of nut 1, and the nut 1 more diameter of great circle pin 4 is more big, but the diameter of straight pin 4 is at least 1mm, generally is no more than 4mm.Described arc wedge groove about in the of 2 both sides all in nut 1 inside, be that the height of arc wedge groove 2 is less than the thickness of nut 1, and the two ends of groove all do not communicate with nut 1 upper and lower surface, and the base 5 of arc wedge groove 2 convex platforms 6 relative sides and the angle of nut 1 axial direction are less than 90o, a side direction that is 6 close nut 1 medial axis, base has a down dip, be convenient to processing so on the one hand, also make elastomer block 3 and straight pin 4 install more convenient.
During this nut combinations, at first straight pin 4 is sticked on elastomer block 3 sides, the more suitable glue of elastomer block 3 usefulness is sticked in the nut 1 endoporus arc wedge groove 2.Adopt interim plug sleeve to fix steel ball or annular knurl roller pin because common antitheft locking element, the plug sleeve that is seen everywhere at the construction field (site) is scattered on the ground, the clean difficulty of complete liquidation very big, and the plastics plug sleeve that is lost in the building site can pollute environment.The utility model adopts glue that straight pin 4 is sticked in the arc wedge groove, can cancel interim plug sleeve, has both saved cost, has protected environment again, and is more convenient during use.
Use when this environment protection type straight pin is anti-to unload anti-theft nut, an end of nut 1 convex platform 6 outwardly, be screwed into the bolt forward that matches, form the arc wedge groove of sealing between the bolt outside thread of arc wedge groove 2 and screw-in, after nut 1 locking, elastomer block 3, straight pin 4 by shutoff in arc wedge groove 2.When unscrewing when unloading nut 1 is counter, straight pin 4 under elastomer block 3 thrust all the time in the angle of arc wedge groove 2, thereby play non-slip effect.When anti-stubborn power increase, straight pin 4 is extruded, and moves towards the little direction of arc wedge groove 2 and the angle of bolt formation, and then has formed bigger coupling mechanism force, thereby has reached the good anti-anti-theft feature that unloads.
