Description
Technical field
This utility model relates to a kind of nut.
Background technology
Nut of the prior art mainly uses the versions such as hex nut, when nut is connected with bolt, nut can be threaded together with bolt by spanner, but, this type of nut is easier dismounting, need not after some nuts are combined with bolt in the applied environment of dismounting, in prior art, the nut of said structure form is the most inapplicable.
Utility model content
The purpose of this utility model is to propose a kind of nut, and it adopts the following technical scheme that
A kind of nut, including nut body, arranges female thread in nut body；It is provided with external screw thread outside described nut body；It is provided with limiting section in nut body front end.
Preferably, limiting section is a boss protruding from nut body.
This utility model has the advantage that
Nut structure in this utility model is simple, and it only has a nut body, is provided with external screw thread outside nut body, is provided with limiting section in nut body front end.This utility model can realize the connection between nut and bolt by means of the spanner that this nut is supporting；This nut spanner includes a clamping limb and No. two clamping limbs, number clamping limb front end with No. two clamping limb front ends for being articulated and connected, a clamping limb is provided with an arcuate groove, No. two clamping limbs are provided with No. two arcuate grooves, in an arcuate groove and No. two arcuate grooves, are equipped with internal thread segment；When utilizing nut spanner that nut is fastened with bolt, a number clamping limb and No. two clamping limbs are placed at limiting section, and nut body is positioned at and is combined, by an arcuate groove and No. two arcuate grooves, the circular trough formed, have in this circular trough with nut body outside the adaptive female thread of external screw thread, by rotating together with nut can screw up by nut spanner easily with bolt.Nut in this utility model is non-dismountable after installing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of nut in this utility model；
Fig. 2 is the structural representation of the spanner adaptive with nut in this utility model, shows a kind of state in figure；
Fig. 3 is the structural representation of the spanner adaptive with nut in this utility model, shows another kind of state in figure；
Wherein, 1-nut body, 2-female thread, 3-limiting section, number clamping limb of 4-, No. bis-clamping limbs of 5-, number arcuate groove of 6-, No. bis-arcuate grooves of 7-, 8-circular trough, 9-external screw thread, 10-female thread.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in further detail by detailed description of the invention:
Shown in Fig. 1, a kind of nut, including nut body 1, female thread 2 is set in nut body 1；External screw thread 9 it is provided with outside nut body 1；It is provided with limiting section 3 in nut body 1 front end.
Preferably, this limiting section 3 is a boss protruding from nut body 1.
The spanner that nut in this utility model can be given with this utility model with the use of.
As in figure 2 it is shown, a kind of nut spanner, including a clamping limb 4 and No. two clamping limbs 5, the front end of the front end of a clamping limb 4 and No. two clamping limbs 5 is for being articulated and connected.
Being provided with an arcuate groove 6 on a clamping limb 4, be provided with No. two arcuate grooves 7 on No. two clamping limbs 5, an arcuate groove 6 is oppositely arranged with No. two arcuate grooves 7, is equipped with internal thread segment in an arcuate groove 6 and No. two arcuate grooves 7.
A number arcuate groove 6 and No. two arcuate grooves 7 meet following relation, it may be assumed that
When an arcuate groove 6 forms a complete circular trough 8 when No. two arcuate grooves 7 are combined, and the internal thread segment in an arcuate groove 6 forms the female thread 10 of circular trough with the internal thread segment combination in No. two arcuate grooves 7, as shown in Figure 3.
The external screw thread 9 arranged outside this female thread 10 and nut body 1 matches.
When carrying out nut and being connected with bolt, a number clamping limb 4 and No. two clamping limbs 5 are placed at limiting section 3, then a clamping limb 4 and No. two clamping limbs 5 are drawn close to centre, nut body 1 is in the circular trough 8 formed by an arcuate groove 6 and No. two arcuate grooves 7, hold with a firm grip a clamping limb 4 and No. two clamping limbs 5 turn, to realize the connection of nut and bolt.
Nut screw up with bolt together with after, by a clamping limb 4 and No. two clamping limbs 5 separately, remove nut spanner.Nut in this utility model is disposable nut, cannot be carried out dismounting with bolt after being connected.
Certainly; only preferred embodiment of the present utility model described above; this utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the teaching of this specification; the all equivalents made substitute, obvious variant, within all falling within the essential scope of this specification, and ought to be by protection of the present utility model.
