Description

TECHNICAL FIELD

The present disclosure relates to a disassembly and assembly tool technical field, and more particularly to a nut sleeve.

BACKGROUND

A socket is a tool used to tighten or loosen nuts and bolts. It is usually made of metal and has a hollow cylindrical structure with a cross-section inside that adapts to nuts of different types and sizes. Common cross-sections include: hexagonal, triangular, pentagonal, etc. The socket is used in conjunction with a wrench or spanner handle to provide leverage so that sufficient force can be applied to tighten or loosen the nut. This tool is often used in mechanical repair, automotive maintenance and construction to effectively complete the removal and installation of nuts and bolts.

Since the traditional socket is made entirely of metal, it will wear out after prolonged usage, and the inner wall of the socket will lose its precision of the original shape, which it becomes easy to slip when works on the nuts or bolts, resulting in the inability to tighten or loosen the nuts or bolts. Over time, the socket is in a scrap state, and the entire socket is usually replaced, resulting in a huge waste of resources and a significant increase in costs. For example, Chinese Patent No. CN2132595Y, titled “multi-faceted sleeve head for sleeve wrenches, and Chinese Patent No. CN 2633519Y, titled “Mult-functional sleeve head”, these existing sockets as disclosed are all made of metal material as a whole, and all have the above-mentioned technical insufficiency.

In view of this, the inventor proposes the following technical solution.

DETAILED DESCRIPTION

The present disclosure is further described below in conjunction with specific embodiments and accompanying drawings. In particular, the nut sleeve is for working on the car wheels.

Referring to FIGS. 1 to 4, the socket of the present disclosure includes a head 1 and a body 2, and the inside of a first socket hole 21 of the body 2 is equipped with an inner plastic sleeve 3 attached to the inner wall thereof. The inner plastic sleeve 3 can be easily removed away from the body 2 and replaced.

The head part 1 is capable of docking with an angle wrench or spanner handle which drive the head part's rotation. The inner plastic sleeve 3, as positioned within the first socket hole 21, is configured to mat with a nut of bolt and drives its rotation. The inner plastic sleeve 3, as provided inside the body 2, not only can it increase the friction in contact with the nut or bolt, which increases the efficiency of the socket operation, the user can also replace the inner plastic sleeve 3 when the inner plastic sleeve 3 is damaged or slips after multiple uses. As the user only need to replace the inner plastic sleeve 3 instead of replacing the entire metal socket, the present invention significantly reduces the operation costs, saves social resources, and avoid unnecessary waste.

The cross section of the first socket hole 21 is any one of hexagon, pentagon, and triangle, and the shape of the inner plastic sleeve 3 is consistent with the shape of the cross section of the first socket hole 21 and attached to the inner wall of the first socket hole 21. The inside of the first socket hole 21 is provided with an inner step 22 adapted to position the inner plastic sleeve 3, and one end of the inner plastic sleeve 3 is provided with an inner extension edge 31 for pressing against and being positioned by the inner step 22. The contact of the inner step 22 with the inner extension edge 31 provides an inclined transition surface for easy pulling. The inner plastic sleeve 3 and the inner wall of the first socket hole 21 are bonded by any adhesive selected from structural glue, ab glue, and quick-drying glue.

The intersection of every two adjacent edge lines of the cross section of the first socket hole 21 is provided with an inverted inner circular corner 211, which is recessed toward the inner wall. The intersection of every two adjacent surfaces of the outer wall of the inner plastic sleeve 3 is provided with an inverted outer circular corner 32 corresponding to the inverted inner circular corner 211. The first socket hole 21 and the inner plastic sleeve 3 are respectively provided with the inverted inner circular corners 211 and the inverted outer circular corners 32. The inverted outer circular corners 32 is employed to prevent any breakage on the inner plastic sleeve 3 caused by the stress concentration at the corners between any two adjacent side surfaces of the inner plastic sleeve 3. Such that it increases the usable life of the inner plastic sleeve 3, and the inverted inner circular corner 211 further allows the inner plastic sleeve 3 and the first socket hole 21 to be attached more tightly, so as to ensure that there is no relative sliding between the inner plastic sleeve 3 and the body 2 during operations.

The head part 1 is provided with a second socket hole 11 for docking and matching with the nut or bolt head, where the cross section of the second socket hole 11 is a hexagon, pentagon or triangle, and the second socket hole 11 is smaller than the first socket hole 21. As the inside of the head part 1 is provided with the second nut sleeve hole 11, it allows the head part 1 also performs a docking operation with a polygonal nut or bolt, such as a hexagonal nut or bolt, which it provides a socket with two connecting ends, thereby improving the scope of use and increasing versatility.

The outer wall of the head part 1 is at least provided with a section of hexagonal head 12 used to dock and match with a nut or bolt head. An extended-through communication path 13 is provided between the first socket hole 21 and the second socket hole 11. The head part 1 is provided with two sections of hexagonal heads 12 of different sizes. The head part 1 is provided the two sections of hexagonal heads 12 of different sizes, so that the socket can be used with inner angle nuts of different sizes, and the hexagonal head 12 of the head part 1 can enable the nut sleeves of different sizes to be stacked on top of each other for easy storage.

The outer wall of the socket body 2 is further sleeved with an outer plastic sleeve 4 capable of being disassembled, assembled and replaced. The socket body 2 is also provided with an outer step 23 adapted to position the outer plastic sleeve 4. The inner plastic sleeve 3 and the outer plastic sleeve 4 are made of POM. The outer plastic sleeve 4 is sleeved on the body 2, the outer plastic sleeve 4 can increase friction, it provides convenience for manually twisting the socket when auxiliary tools cannot be used in a small space, thereby increasing the applicable range of the socket.

In summary, when operate the socket as disclosed in the present disclosure, the socket body 2 is matted with the wheel bolt head of the automobile, allowing the inner plastic sleeve 3 to be touched the bolt head. The wrench or spanner handle is used to dock the head 1. Since the head 1 has both a hexagonal head 12 and a second socket hole 11, an inner hexagonal wrench or an outer hexagonal wrench can be used to connect with the head 1 and to rotate the socket for removing or installing the bolts. The use of the inner plastic sleeve 3 to contact the bolt head will increase the friction of the contact, avoid slipping, and generate greater torque on the bolt. The inner plastic sleeve 3 also can be replaced in time when it is broken due to stress. There is no need to replace the entire socket, such it increases the service life of the socket, reduces usage costs, and saves social resources.

Of course, the above are only specific embodiments of the present disclosure and are not intended to limit the implementation scope of the present disclosure. Any equivalent changes or modifications made in accordance with the structure, features and principles described in the claims of the present disclosure should be included in the claims of the present disclosure.
