Description

A kind of tightening structure of round pipe with holes

technical field

The utility model relates to the field of mechanical assembly, in particular to a screwing structure of a round pipe with holes.

Background technique

Existing round pipes with holes on the surface and threads on the end surface are usually tightened with pliers. Since the force point of the pliers is the surface of the pipe when tightening the tubular objects, it is easy to damage the surface or deform the clamp. cause the product to be scrapped.

Utility model content

In order to overcome all the deficiencies of the existing related products, the utility model proposes a screwing structure of a round pipe with holes. This structural scheme can not be clamped very tightly when screwing objects with holes on the surface of the round pipe and threads on the end face, and It will not slip when tightening, and will not deform the product or scratch the outer wall.

The technical scheme that the utility model solves its technical problem adopts is:

A tightening structure of a round pipe with a hole provided by the utility model includes: a top screw, a locking ring, a handle, and a round tube; the top screw is located on the internal thread feature of the locking ring, and its Cylindrical features are exposed in section, and the round tube is located in the circular space between the handle and the locking ring.

As a further improvement of the utility model, it also includes a knob, the knob is screwed on one end of the locking ring, the other end of the locking ring is pivotally connected to one end of the handle, and the opposite end of the handle is connected to the locking ring The port is provided with a U-shaped groove, and the knob cooperates with the U-shaped groove to form a circular space between the handle and the locking ring.

As a further improvement of the utility model, the end of the locking ring connected to the handle may also include a cylindrical pin, and the locking ring can rotate around the handle under the cooperation of the cylindrical pin.

As a further improvement of the utility model, the cylindrical feature of the jack screw is directly facing the round tube hole on the round tube and inserted into it.

Compared with the prior art, the utility model has the following advantages:

1. Since the top screw is inserted into the hole of the round tube, the stress point is transferred to the junction of the top screw and the hole of the round tube, so the surface of the round tube will not be scratched when the round tube is tightened;

2. Since the point of force is not on the surface of the round tube, when the round tube is tightened, it will not be deformed due to excessive force, which effectively protects the integrity of the appearance.

detailed description

In order to facilitate the understanding of the utility model, the utility model will be described more fully below with reference to the relevant drawings. Preferred embodiments of the utility model are provided in the accompanying drawings. However, the invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present utility model more thorough and comprehensive.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of this invention. The terminology used in the description of the utility model herein is only for the purpose of describing specific embodiments, and is not intended to limit the utility model.

Referring to FIG. 1 and FIG. 2 , the tightening structure of the perforated circular tube includes a top screw 1 , a locking ring 2 , a handle 3 , a knob 4 , a cylindrical pin 5 and a circular tube 6 .

The locking ring 2 is arc-shaped, the screw 1 is located on the internal thread feature of the locking ring 2, and the cylindrical feature of the screw 1 is exposed from the cross section, and the length of the exposed section is selected according to the specific situation. The preferred embodiment is 2mm, and the protection range is not limited to 2mm.

The knob 4 is screwed on one end of the locking ring 2, and the other end of the locking ring 2 is assembled on one end of the handle 3 through a cylindrical pin 5. The handle 3 includes a grip and a clip connected to the grip. Tightening part, in this embodiment, the gripping part and the clamping part are integrally formed, the clamping part is arc-shaped, and is pivotally connected with the locking ring 2, and the handle 3 is connected with the locking ring 2 The port at the opposite end is provided with a U-shaped groove 30, and the locking ring 2 rotates around the handle 3 under the cooperation of the cylindrical pin 5, and moves closer to the end of the handle 3 with the U-shaped groove 30, so that the knob 4 passes through the U-shaped groove 30. Type groove 30, and the locking ring 2 and the handle 3 are fixed by tightening the knob 4. The round tube 6 is located in the circular space formed by the locking ring 2 and the handle 3, and the cylindrical feature of the top screw 1 is facing the round tube hole 60 on the round tube 6 and inserted into it. The sizes of the locking ring 2 and the handle 3 can be set and adjusted according to the diameter of the round tube 6 .

When it is necessary to tighten the round pipe, operate the tightening structure of the perforated round pipe, the operation steps are:

Step S1: Put the round tube 6 into the tightening structure, and make the cylindrical feature of the tightening screw 1 of the tightening structure face the round tube hole 60 on the round tube 6 and insert it, and fix the round tube 6 in the tightening structure. structurally;

Step S2: close the locking ring 2 to the end of the handle 3 with the U-shaped groove 30;

Step S3: After the knob 4 passes through the U-shaped groove 30, tighten the knob 4 to fix the locking ring 2 and the handle 3;

Step S4: Operate this structure to tighten the round tube 6 and other items.

The above-mentioned embodiment is a preferred implementation mode of the present utility model, but the implementation mode of the present utility model is not limited by the above-mentioned embodiment, and any other changes, modifications and substitutions made without departing from the spirit and principle of the present utility model , combination, and simplification, all should be equivalent replacement methods, and are all included in the protection scope of the present utility model.
