Description

A kind of stop nut

Technical field

This utility model relates to a kind of securing member, more specifically, it relates to a kind of stop nut.

Background technology

Nut generally uses with bolt, screw fit; play the effect connecting fastening parts; when using common hex nut and bolt to lock parts; in order to prevent nut loosening; after the most first overlapping spring washer on bolt; again nut is screwed on bolt by spanner; the elastic force relying on spring washer increases the frictional force that nut matches between screw thread with bolt; and then prevent loosening of nut; but in actual application; carrying out locking effect by the upper spring washer of pad less desirable, nut is often it also occur that the phenomenon loosened.

Utility model content

The deficiency existed for prior art, this utility model is to provide a kind of stop nut, and by installing cam at nut body, cam rotates conflicts with bolt, reaches the purpose making nut body be not susceptible to loosen phenomenon.

For achieving the above object, this utility model provides following technical scheme: a kind of stop nut, including nut body, tapped through hole is offered on described nut body, described nut body is rotatably connected to cam, and described cam rotates forward conflicts with bolt, reversely rotates and separates with bolt.

By using technique scheme, by cam is conflicted with bolt, make cam to the screw thread build-up of pressure on bolt, so that nut body produces pressure to bolt, reduce the gap between the screw thread on tapped through hole and bolt, add contact area so that bolt can abut against on the inwall of tapped through hole, thus increasing the frictional force between the screw thread that nut body matches with bolt so that nut body is not susceptible to loosen.

This utility model is further arranged to: the contact surface that described cam and bolt are conflicted is that indent is arranged.

By using technique scheme, the contact surface of indent, the contact area with bolt can be increased, increase the frictional force between cam, and the contact surface of indent has positioning action, it is to avoid cam arbitrarily rotates.

This utility model is further arranged to: be fixed with handle on described cam.

By using technique scheme, it is simple to cam is rotated by workman, promote the production efficiency of workman.

This utility model is further arranged to: described nut body is that six prisms are arranged.

By using technique scheme, it is simple to workman will rotate nut body, promote the production efficiency of workman further.

This utility model is further arranged to: one end of described nut body is fixed with the connection ring for conflicting with parts.

By using technique scheme, connecting ring can increase the contact area between nut body and parts, reduces the pressure that parts are produced by nut body, reduces the abrasion of parts.

This utility model is further arranged to: offer anti-slip tank on described connection ring.

By using technique scheme, anti-slip tank can increase the contact area with parts, increasing friction force further so that nut body is difficult to produce relative rotation between parts.

This utility model is further arranged to: described connecting is fixed with the elastic component arranged with parts conflict on ring.

By using technique scheme, the setting of elastic component so that increase nut body and match with bolt the frictional force of screw thread, improve the stability maintenance of nut body further, make nut body be not susceptible to the phenomenon loosened.

In sum, this utility model has the advantages that

Conflict with parts by ring will be connected, anti-slip tank and the setting of elastic component, nut body is difficult to parts and produces relative rotation, add the stability maintenance of nut body, then by handle, cam is rotated, the contact surface of cam is made to conflict with the screw thread of bolt, add the pressure between bolts and nuts body, pressure is converted into frictional force, coordinating between nut body with bolt can more be stablized, improve the stability maintenance of nut body further so that nut body is not susceptible to the phenomenon loosened.

Detailed description of the invention

Referring to figs. 1 through Fig. 5, this utility model one stop nut is described further.

As shown in Figures 1 to 5, a kind of stop nut, including the nut body 1 in six prisms, the central authorities at nut body 1 offer the tapped through hole 11 matched with bolt；The connection ring 2 of an annular it is fixed with on one end face of nut body 1, connect the diameter catercorner length more than nut body 1 cross section of ring 2, the contact surface 31 increasing between nut body 1 and parts by connecting ring 2 amasss, reduce and parts are produced pressure so that the surface of parts will not produce bigger abrasion.

As shown in Figure 4, some anti-slip tanks 22 are offered connecting the ring 2 side back to nut body 1, anti-slip tank 22 is along the axial uniform setting connecting ring 2, increased the contact surface 31 connected between ring 2 and parts to amass by anti-slip tank 22, increase frictional force, make nut body 1 be not likely to produce relative rotation with parts；Connecting ring 2 and offering back to the side of nut body 1 groove 21 of an annular, groove 21 is being provided with elastic component 23, in the present embodiment, elastic component 23 is spring, one end of spring is fixed in groove 21, and the other end stretches out from groove 21, in order to conflict with parts.

As depicted in figs. 1 and 2, offering the groove 12 of a rectangle on the sidewall of nut body 1, groove 12 connects the inwall of sidewall and tapped through hole 11, is rotatably connected to a rotary shaft 5 on the inwall of groove 12；The axis parallel of the axle center of rotary shaft 5 and tapped through hole 11 is arranged, and sheathed in rotary shaft 5 is fixed with a cam 3；As it is shown in figure 5, cam 3 includes upper and lower end face, contact surface 31 and two planes, contact surface 31 is arranged in indent.

Cam 3 is further fixed on a rectangular handle of cross section 4, it is simple to workman holds.

During use, as shown in Figure 3, tapped through hole 11 and bolt are coordinated, rotate nut body 1, connection ring 2 is made to conflict with parts, spring deforms upon simultaneously, produce elastic force, increase the frictional force of screw thread between nut body 1 and bolt, then by handle 4 is rotated along the axle center of rotary shaft 5, as shown in Figure 2, handle 4 band moving cam 3 is rotated forward, the contact surface 31 of cam 3 is conflicted towards bolt and with the screw thread on bolt, so that cam 3 applies pressure radially to bolt, the cooperation making bolts and nuts body 1 is tightr, further increase the frictional force between bolts and nuts body 1, bolt is difficult to nut body 1 and produces relative rotation, it is achieved thereby that this utility model is a kind of loosens the phenomenon that nut is not susceptible to loosen；When handle 4 band moving cam 3 is reversely rotated by needs, cam 3 can be made to separate with bolt, thus reduce the frictional force between bolts and nuts body 1, consequently facilitating nut body 1 is separated with bolt by workman.

In the present embodiment, for the ease of processing and manufacturing, by cam 3 and handle 4 integrated setting.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
