[0025] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] An embodiment of the utility model provides a manual clamping tool for a seamless steel gas cylinder, comprising a first clamping structure, a second clamping structure and a rotating structure; the first clamping structure and the second clamping structure form a circular clamping ring adapted to the seamless steel gas cylinder, and the two can generate relative rotation through the rotating structure, thereby completing the clamping and fixation of the seamless steel gas cylinder.

[0027] In conjunction with the accompanying drawings, various structures of the manual clamping tool for seamless steel gas cylinders provided by the embodiment of the utility model, as well as the positional relationship and connection relationship between the various structures are described in detail below.

[0028] like Figures 1 to 4 As shown, in the embodiment of the utility model, the first clamping structure 10 includes a first semicircular portion 11 and a first lever portion 12, and one end of the first lever portion 12 is connected to the first end of the first semicircular portion 11. For example, the vertical projection of the first semicircular portion 11 to the first lever portion 12 is within the range of the first lever portion 12, that is, as shown in the perspective in the figure, the first semicircular portion 11 is the left half of the manual clamping tool;

[0029] The second clamping structure 20 includes a second semicircular portion 21 and a second lever portion 22, and one end of the second lever portion 22 is connected to the first end of the second semicircular portion 21. For example, the vertical projection of the second semicircular portion 21 to the second lever portion 22 is outside the range of the second lever portion 22, that is, as shown in the perspective of the figure, the second semicircular portion 21 is the right half of the manual clamping tool.

[0030] The first lever portion 12 and the second lever portion 22 are both straight rod structures, wherein parameters such as length, shape and outer diameter of the first lever portion 12 and the second lever portion 22 can be determined according to the use environment of the manual clamping tool, for example, according to the outer diameter and mass of the steel seamless gas cylinder 50 to be clamped.

[0031] In the embodiment of the utility model, an anti-skid structure is provided on the first lever arm portion 12 and / or the second lever arm portion 22. By providing the anti-skid structure, the friction between the operator's hand and the first lever arm portion 12 and the second lever arm portion 22 can be increased, and the slipping phenomenon can be avoided / reduced, making the operation more stable, labor-saving, and comfortable.

[0032] For example, the anti-slip structure includes a rubber sleeve sleeved on the first lever arm portion 12 and / or the second lever arm portion 22. For example, the aperture of the rubber sleeve is smaller than the outer diameter of the first lever arm portion 12 and the second lever arm portion 22, so that the two can be tightly connected to avoid relative sliding during use. For example, the length of the rubber sleeve is not less than 100 mm, and the rubber sleeve covers a sufficient area to prevent the operator's hand from directly contacting the first lever arm portion 12 or the second lever arm portion 22.

[0033] Continue to refer Figures 1 to 4 As shown, in the embodiment of the utility model, the first end of the first semicircular portion 11 and the first end of the second semicircular portion 21 are rotatably connected through a rotating structure 30; the first semicircular portion 11 and the second semicircular portion 21 form a circular clamping ring for clamping a seamless steel gas cylinder 50. The second end of the first semicircular portion 11 and the second end of the second semicircular portion 21 form a clamping opening, and the first semicircular portion 11 and the second semicircular portion 21 rotate relative to each other through the rotating structure 30 to adjust the diameter of the circular clamping ring. For example, the diameter of the circular clamping ring ranges from 150 mm to 300 mm.

[0034] During the clamping operation, the first force arm portion 12 and the second force arm portion 22 are relatively separated, so that the opening of the clamp becomes larger, so that the circular clamping ring can be sleeved on the outer wall of the steel seamless gas cylinder 50; then, by pressing the first force arm portion 12 and the second force arm portion 22, the first force arm portion 12 and the second force arm portion 22 are relatively close. At this time, the diameter of the circular clamping ring gradually decreases, so that the circular clamping ring hugs the outer wall of the steel seamless gas cylinder 50 to achieve a fixing effect.

[0035] For example, connecting holes are respectively provided at the connecting position between the first lever arm portion 12 and the first semicircular portion 11 and at the connecting position between the second lever arm portion 22 and the second semicircular portion 21. The rotating structure 30 is a rotating shaft which is passed through the connecting holes, thereby realizing relative rotation between the first semicircular portion 11 and the second semicircular portion 21.

[0036] In the embodiment of the utility model, the first lever portion 12 and the second lever portion 22 are both in the shape of a straight rod; and the first semicircular portion 11, the second semicircular portion 21 and the second lever portion 22 are located on the same side of the first lever portion 12. From the perspective shown in the figure, in this structure, the rotation connection structure of the first clamping structure 10 and the second clamping structure 20 is located at the upper position, and the clamping opening is located at the lower position.

[0037] During operation, the opening of the clamp is adjusted to be larger, and the seamless steel cylinder 50 is placed from above or below, and then the first arm portion 12 and / or the second arm portion 22 are pressed. This structural design makes the structure of the manual clamping tool simpler and occupies less space, and during operation, the influence of surrounding structures and space can be reduced.

[0038] Continue to refer Figures 1 to 4 As shown, in the embodiment of the utility model, the first clamping structure 10 and the second clamping structure 20 include a clamping surface, and the clamping surface includes a clamping layer 40 for increasing friction with the steel seamless gas cylinder 50. By providing the clamping layer 40, the friction between the clamping surface and the surface of the steel seamless gas cylinder 50 can be increased, the stability of the clamping can be ensured, and by providing the clamping layer 40, the clamping operation can be relatively more labor-saving, and the convenience of operation is improved.

[0039] For example, the clamping layer 40 includes an anti-skid rubber layer; the anti-skid rubber layer on the first clamping structure 10 and the second clamping structure 20 forms a continuous annular structure. While meeting the above functional requirements, the anti-skid rubber layer can also avoid scratching the seamless steel gas cylinder 50 and protect the seamless steel gas cylinder 50.

[0040] The embodiment of the utility model provides a manual clamping tool for a seamless steel gas cylinder 50. When in use, the circular clamping ring formed by the first semicircular portion 11 and the second semicircular portion 21 is set on the outside of the seamless steel gas cylinder 50, and then pressure is applied to the first annular portion and / or the second annular portion to make the two rotate relative to each other, so that the first semicircular portion 11 and the second semicircular portion 21 hold the outer wall of the seamless steel gas cylinder 50 tightly to prevent the seamless steel gas cylinder 50 from rotating when in use. The technical solution of the utility model can perform a tightening clamping operation on the seamless steel gas cylinder 50, prevent the seamless steel gas cylinder 50 from rolling and rotating freely, and facilitate the disassembly and assembly of the bottle valve, and the clamping tool also has the advantages of simple structure, lighter weight, no restrictions on location, and low cost.
