Open sleeve

Abstract

The utility model discloses an opening sleeve which comprises a connecting column, the lower end of the connecting column is fixedly connected with a sleeving cylinder, a nut sleeving groove is integrally formed in the lower end of the inner side wall of the sleeving cylinder, and a receding groove is formed in the outer side wall of the sleeving cylinder. When in use, a common screw and nut can be disassembled and assembled, the use mode is the same as the use mode of a common sleeve, and for a screw with a wire harness in the middle, the wire harness can be thrown out from the receding groove when being disassembled and assembled, so that the wire harness is prevented from falling off from the position of the receding groove. Therefore, the open sleeve provided by the utility model can be suitable for dismounting and mounting of most types of screws and nuts.

Description

Technical Field

[0001] The utility model relates to the technical field of sleeves, in particular to an open sleeve. Background Art

[0002] When installing and removing screws and nuts, people often use sleeves for assembly for convenience and speed. However, most of the sleeves nowadays are straight sleeves. Therefore, for some screws with wiring harnesses in the middle, straight sleeves cannot be disassembled and assembled adaptively. In view of the above problem, an open sleeve is proposed. Utility Model Content

[0003] The purpose of the utility model is to provide an open sleeve to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an open sleeve, comprising a connecting column, the lower end of which is fixedly connected to a sleeve tube, the lower end of the inner wall of the sleeve tube is integrally formed with a nut sleeve groove, and the outer wall of the sleeve tube is provided with a clearance groove.

[0005] Preferably, the lower end of the nut sleeve groove is integrally formed with an extended chamfer.

[0006] The beneficial effects of the utility model are:

[0007] When the utility model is in use, ordinary screw nuts can be disassembled and installed, and the usage method is the same as that of ordinary sleeves. For the screw with the wiring harness installed in the middle, the wiring harness can be thrown out from the give way groove during disassembly and installation, so that the open sleeve proposed by the utility model can be suitable for disassembly and installation of most types of screw nuts. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of the structure of the utility model;

[0009] Figure 2 It is a schematic diagram of the bottom structure of the utility model.

[0010] In the figure: connecting column 1, sleeve tube 2, nut sleeve groove 3, clearance groove 4, extended chamfer 5. DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] See also Figure 1-2 The utility model provides a technical solution: an open sleeve, including a connecting column 1, the lower end of the connecting column 1 is fixedly connected with a sleeve tube 2, the lower end of the inner side wall of the sleeve tube 2 is integrally formed with a nut sleeve groove 3, and the outer side wall of the sleeve tube 2 is provided with a clearance groove 4.

[0013] Specifically, an extended chamfer 5 is integrally formed at the lower end of the nut sleeve groove 3 .

[0014] The extended chamfer 5 is used to facilitate the insertion of the screw or nut into the nut sleeve groove 3.

[0015] Working principle: When the utility model is in use, ordinary screw nuts can be disassembled and installed, and the usage method is the same as that of ordinary sleeves. For the screw with the wiring harness installed in the middle, the wiring harness can be thrown out from the give way groove 4 during disassembly and installation, so that the open sleeve proposed by the utility model can be suitable for disassembly and installation of most types of screw nuts.

[0016] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
