Description

Reducing bolt and nut

Technical Field

The utility model relates to a extracting tool technical field specifically is a reducing bolt and nut.

Background

The nut is a nut, is a part which is screwed together with a bolt or a screw rod to play a fastening role, and needs to be used for reducing bolts and nuts in most scenes so as to obtain a better effect.

However, in the open air or in a scene with long installation time, the bolt and the nut are easy to oxidize, and in the process of disassembly and replacement, the nut or the bolt and a disassembling tool are easy to relatively rotate, so that disassembly and replacement are not facilitated, and great influence is caused on subsequent work.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a not enough to prior art, the utility model provides a reducing bolt and nut possesses and can prevent that nut or bolt from producing relative pivoted advantage in the in-process of unscrewing or screwing up, has solved because of the easy oxidation of bolt and nut causes very big influence to subsequent work, and then has improved work efficiency's problem.

(II) technical scheme

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a reducing formula bolt and nut, includes the hexagonal buckle, be equipped with a support section of thick bamboo on the hexagonal buckle, support a female connection and have the lead screw, the one end of lead screw stretches into in the hexagonal buckle and with the nut contact, the other end of lead screw stretches out support the section of thick bamboo and just be connected with the dwang outward.

Preferably, the support cylinder is provided with a through hole, and the screw rod is also provided with a plurality of holes.

Preferably, the support cylinder is in threaded connection with the hexagonal buckle.

Preferably, the support cylinder and the hexagonal buckle are cast into a whole.

Preferably, one end of the screw rod, which is in contact with the nut, is flat.

Preferably, the inner wall of the hexagonal buckle is provided with a rubber pad.

(III) advantageous effects

The utility model provides a reducing bolt and nut possesses following beneficial effect:

this reducing formula bolt-nut through setting up a supporting cylinder (2) and lead screw (3) threaded connection, not only can adapt to not equidimension nut or bolt, but also can prevent to produce relative rotation between nut or bolt and the extracting tool, has solved and has produced relative pivoted problem between nut or bolt and the extracting tool, has reached and then has improved work efficiency's purpose.

FIG. 1 is a schematic perspective view of the present invention;

FIG. 2 is a schematic middle section view of the present invention;

fig. 3 is a schematic view of a flat structure on the middle screw rod of the present invention.

In the figure: 1. a hexagonal fastener; 2. a support cylinder; 21. a through hole; 3. a screw rod; 31. flat shape; 4. rotating the rod; 5. and a nut.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, a variable diameter bolt and nut includes a hexagonal buckle 1, a support cylinder 2 is disposed on the hexagonal buckle 1, a lead screw 3 is connected to the support cylinder 2 via an internal thread, one end of the lead screw 3 extends into the hexagonal buckle 1 and contacts with a nut 5, and the other end of the lead screw 3 extends out of the support cylinder 2 and is connected with a rotating rod 4; hold dwang 4 and will support a section of thick bamboo 2 and rotate, because support a section of

thick bamboo

2 and 3 threaded connection of lead screw, consequently when manual rotation dwang 4, can with 3 precession hexagonal buckles of lead screw 1 in, make hexagonal buckle 1 more inseparable with the contact of nut 5, can come the range of adjusting screw 3 precession according to the size of nut 5, prevent that nut 5 and hexagonal buckle 1 from producing relative rotation in operation process, be unfavorable for dismantling work.

Referring to fig. 1 and 2, the support cylinder 2 and the hexagonal fastener 1 are connected by screw threads or cast integrally; when the supporting cylinder 2 is in threaded connection with the hexagonal buckle 1, the portable hexagonal socket can be conveniently carried, and the occupied volume of the device is reduced.

Referring to fig. 3, one end of the screw rod 3 contacting the nut 5 is flat 31; the flat shape 31 can increase the contact area with the nut 5, thereby increasing the friction force between the screw rod 3 and the nut 5 and being beneficial to operation.

Referring to fig. 1, a rubber pad is arranged on the inner wall of the hexagonal buckle 1; the rubber pad that sets up can increase the frictional force when contacting with nut 5, is favorable to unscrewing nut 5.

The working principle is as follows: during the use, hold dwang 4 and unscrew lead screw 3, then put nut 5 in hexagonal buckle 1, when nut 5 placed, rotate dwang 4 again and screw in lead screw 3, and with nut 5 in close contact with, a support section of thick bamboo 2 can freely be adjusted according to the size of nut 5 with 3 threaded connection of lead screw is convenient, when placing and finishing, insert into through-hole 21 through outside horizontal pole in, prevent in the course of the work, lead screw 3 produces ascending removal, platykurtic 31 can increase the area of contact with nut 5, and then increase frictional force, be favorable to unscrewing nut 5.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
