Abstract

A sheath structure of a pneumatic sleeve. The sheath is sleeved on an outer peripheral wall of a sleeve body. The outer peripheral wall of the sleeve body has a first limiter, and the inner peripheral wall of the sheath corresponds to the sleeve The first limiter of the main body is provided with a second limiter, by which the sheath can form a limit and pivot on the sleeve body through the first limiter and the second limiter Therefore, when the sleeve body is rotated by a pneumatic tool, the sheath can maintain a static state, thus avoiding the outer periphery of the sheath and the nut (or bolt) and nut (or bolt) to be rotated The attached object produces friction, which reduces the phenomenon of scratches and wear between the object and the sheath, thereby increasing the service life of the sheath.

Description

Jacket structure of pneumatic sleeve

This creation is related to pneumatic sleeves, especially a jacket structure of pneumatic sleeves.

In general, the system of the sleeve is completely made of metal material. The two ends of the sleeve are respectively provided with an engaging end and a fitting end. The engaging end can be engaged with a pneumatic tool. The fitting end can be fitted into A nut (or bolt), by which the sleeve can be driven to rotate by the action of the pneumatic tool, and then the nut (or bolt) can be locked or unscrewed.

However, when using the aforementioned conventional sleeve to unscrew or screw the nut (or bolt), the sleeve often strikes the nut (or bolt) or the attached work piece, because when using a pneumatic tool to quickly rotate the sleeve, The sleeve made of metal is more likely to rub against the nut (or bolt) or the attached workpiece, causing scratches and wear. In particular, taking the replacement of an automobile tire as an example, when the sleeve is quickly rotated, it is easy to cause scratches and wear on the edges of each nut (or bolt), or cause scratches on the surface of the rim to which the nut (or bolt) is attached Or wear.

Therefore, in view of the above-mentioned phenomenon, some manufacturers provide a protective sleeve made of plastic material on the outer peripheral wall sleeve of the conventional sleeve, which can reduce the phenomenon of scratching and abrasion of objects. However, due to the rotation of the sleeve, the protective sleeve As the sleeve rotates, the protective sleeve often wears itself or even ruptures after several times of rotational friction, thus reducing its service life. Therefore, after observing the above shortcomings, the creator of this case thinks how to avoid scratches, The phenomenon of wear and tear, and increase the service life of the protective sleeve, is really necessary, and this creation has occurred.

The purpose of this creation is to provide a jacket structure for a pneumatic sleeve, which can reduce damage to the nut (or bolt) and its attached work piece to be locked or unscrewed, and increase the service life of the jacket.

In order to achieve the above purpose, the jacket structure of the pneumatic sleeve provided by this creation is sleeved on the outer peripheral wall of a sleeve body, and the two ends of the sleeve body are respectively provided with a joint end for engaging with a pneumatic tool. And a fitting end fitted with a nut (or bolt), the main feature is that: the outer peripheral wall of the sleeve body has a first stopper; the inner peripheral wall of the sheath corresponds to the first A limiter is provided with a second limiter.

The jacket structure of the pneumatic sleeve provided by this creation, because the jacket can pivot on the sleeve body and form a limit, so when the pneumatic tool is actuated to rotate the sleeve body, the jacket can be maintained Static state, thus avoiding friction between the outer periphery of the sheath and the workpiece to which the nut (or bolt) is attached, reducing the phenomenon of scratches and wear between the workpiece and the sheath, thereby increasing the service life of the sheath .

Figure 3 is a schematic diagram of the best embodiment of this creation, to show how the sheath is sleeved on the sleeve body.

Please refer to FIG. 1, which is a front perspective view of the preferred embodiment of the present invention, which discloses a sheath structure of a pneumatic sleeve. The sheath 100 can be sleeved on the outer peripheral wall of a sleeve body 200 Please refer to the second figure, the two ends of the sleeve body 200 are respectively provided with a joint end 201 to be engaged with a pneumatic tool, and a fitting end 202 to be fitted with a nut (or bolt), the main features Lies in:

A first limiter 210 is disposed on the outer peripheral wall of the sleeve body 200. In this embodiment, the first limiter 210 of the sleeve body 200 is ring-mounted on the outer peripheral wall of the sleeve body 200 The formed limiting groove 211.

A second limiting member 10 corresponding to the first limiting member 210 of the sleeve body 200 is disposed on the inner peripheral wall of the sheath 100. In this embodiment, the second limiting member 10 is a plurality of equal parts The bumps 11 are distributed on the inner peripheral wall of the sheath 100.

In order to further evaluate the structural characteristics of the creation, the use of technical means and the expected effect, the use of the creation is described here. I believe that it can be used to have a more in-depth and specific assessment of the creation, as follows:

Please also refer to the third figure, which is a schematic diagram of the use of this creation to show the state that the sheath is sleeved on the sleeve body. In this embodiment, the second limiting member of the sheath 100 is used. 10 The sheath 100 is sleeved on the first limiting member 210 of the sleeve body 200, so that the sheath 100 is restricted, and it is not easy to slip off the sleeve body 200, and the sleeve Body 200 outer circumference A gap is formed between the wall and the inner peripheral wall of the sheath 100. Since the sheath 100 and the sleeve body 200 are not tightly arranged, the sheath 100 can pivot on the sleeve body 200, so When the pneumatic tool actuates and rotates the sleeve body 200, the sheath 100 can maintain a still state when it is pressed or held, thus avoiding the outer periphery of the sheath 100 and the nut (or bolt) to be attached Friction occurs between the workpieces, which reduces scratches and wear between the workpiece and the sheath 100, thereby increasing the service life of the sheath 100.

It is worth mentioning that the top edge of the sheath 100 corresponding to the fitting end 202 of the sleeve body 200 protrudes out of the fitting end 202 of the sleeve body 200 to form a protrusion 12, thereby, When the fitting end 202 of the sleeve body 200 is to be fitted with a nut (or bolt), the protruding portion 12 of the sheath 100 can be pressed against the workpiece, which can avoid the fitting of the sleeve body 200 The end 202 directly touches and impacts with the workpiece, thereby avoiding scratch damage to the surface of the workpiece.

Hereby, the characteristics of this creation and the expected effect that can be achieved are stated as follows:

In this creation, by limiting the second limiting member 10 of the sheath 100 to the first limiting member 210 of the sleeve body 200, the sheath 100 can be sleeved on the outer peripheral wall of the sleeve body 200 and formed Pivot, so when the pneumatic tool is actuated to rotate the sleeve body 200, the sheath 100 can maintain a static state, thus avoiding the occurrence of the gap between the outer periphery of the sheath 100 and the workpiece to which the nut (or bolt) is attached Friction reduces the phenomenon of scratches and wear between the workpiece and the sheath 100, which in turn increases the service life of the sheath 100.

In summary, this creation has its excellent progress and practicality in similar products. At the same time, it has searched domestic and foreign technical information about such structures, and no similar structure exists in the literature. Therefore, This creation has already possessed the requirements for new-type patents.

However, the above are only one of the preferred and feasible embodiments of this creation. Therefore, any equivalent structural changes that apply to this creation specification and the scope of patent application should be included in the scope of the patent of this creation.
