Description

Special sleeve structure for loading and unloading tires

The present invention is a sleeve structure, especially a special sleeve structure for a loading and unloading tire having better structural strength and effectively extending the service life.

According to the special sleeve for loading and unloading tires, as the name implies, it is a special tool for assembling tires for vehicles, so as to cooperate with the relative power tools such as pneumatic or electric, and to carry out the expected loading and unloading operation of the locking screws of the tires. In other words, it usually needs to have strong structural strength to withstand and withstand high-strength torsional stress for a long time.

Therefore, as shown in FIG. 5, it is a conventional special sleeve 40 which is generally used, which is integrally made of a metal material, has a round and straight appearance, and can be subdivided into a set of connecting segments 41 and a The power inserting section 42 is provided with an axial polygonal working hole 43 for fitting the tire locking screw, and the power plugging section 42 is provided with an axial square hole (not shown) ), for the corresponding power output shaft of the power tool is inserted, and one of the radial through holes 44 of the power insertion stage 42 is for reinforcing and positioning with the power output shaft.

Of course, although the conventional products have been widely used for many years, the practitioners who actually use this product in most layers have found that the outermost edge of the socket portion 41 is easily affected by accidental fall or accidental collision. At the same time, the strength load capacity of the socket action section 41 is also obviously insufficient, and it is easy to be cracked and destroyed, thereby giving a short life. The feeling of bad use, it is obvious that this product is necessary to be improved and refined.

Therefore, in view of the above facts, the creators have actively invested in R&D and innovation based on their practical experience in practicing this industry for many years. This creation was born early to benefit the public; therefore, it is mainly for a sleeve. A set of jointing sections is applied to the one-side thickening technique of the circumferential surface, so that it does not increase the manufacturing cost and the processing steps, so that it will inevitably produce a more solid structural strength, in addition to effectively extending the service life, The splicing action segment will be less likely to be severely cracked, and the safety of the relevant practitioners will be ensured. This is the main purpose of the creation.

The present invention is a special sleeve structure for loading and unloading tires, comprising a sleeve having a set of connecting sections, a thin neck buffering section and a power plugging section, the two ends of the narrow neck buffering section are respectively combined The socket action section and the power plug section are provided with an axial polygonal working hole in the socket action section, and the power plug section is provided with an axial square hole and a radial through hole; The front end of the connecting section is provided with a thickening and strengthening portion at one end, and a first-stage thickening and reinforcing portion is provided at the rear end.

The above described objects, features and advantages of the present invention will become more apparent and understood. A special sleeve structure for a loading and unloading tire is disclosed, comprising a sleeve 20 comprising a connecting section 21, a narrow neck buffer section 22 and a power plug section 23, the thin neck buffer section 22 The two ends of the sleeve are respectively coupled to the socket portion 21 and the power socket portion 23, and the sleeve portion 21 is provided with an axial polygonal working hole 24 for fitting the tire locking screw, and the power plugging The segment 23 is provided with an axial square hole 25 and a radial through hole 26 for inserting with the corresponding power output shaft of the power tool for the purpose of achieving the intended transmission power; however, it is mainly at the front end of the socket action section 21. An end edge thickening reinforcement portion 27 is provided, and a rear end thickening and strengthening portion 28 is disposed at a rear end of the socketing action portion 21. With the above structure, the socket action portion 21 can effectively improve the overall structural strength and prevent damage. And extend the life of its characteristics.

Wherein, the edge thickening reinforcement portion 27 can withstand accidental collision and tapping, so that it is less susceptible to damage, and the grade thickening and strengthening portion 28 is positioned adjacent to the narrow neck buffer segment 22 when After the socket action section 21 is subjected to stress exceeding the load capacity and is cracked, the grade thickening and strengthening section 28 can effectively control the cracking range of the material, so that the sleeve action section 21 is not completely cracked or even sprayed, thereby ensuring the protection. Use security.

Furthermore, the function of the narrow neck buffer section 22 is to generate the instantaneous torsional strain capability of the sleeve 20 under stress, that is, to impart high strength and toughness to the material, and to effectively buffer the force, thereby reducing the stress fracture of the material. The risk; however, this buffering force design technique has long been familiar with the various hand tools and related group accessories, and is familiar to the general public, so the creators will not repeat them.

Referring to FIG. 2 and FIG. 4, the sleeve 20 can be used in the socket when it is actually used. With the outer circumference of the segment 21, an outer ring rubber sleeve 30 of one of the corresponding cylindrical shapes is overlaid so as not to injure the tire aluminum ring by collision.

Looking at the above, before the application, the creation of this creation has not only been found in the market of similar products and related publications, but also has the practical value and positive benefits of "new" and "progress". Cheng has already met the application requirements of the new patent, and it is reasonable to obtain The protection of the patent law, 提出 apply in accordance with the law.
