Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a combined nut. Background Art

[0002] Traditional nuts are a whole, usually used with bolts, screws or screws with smooth shafts. However, nuts can become stuck due to rust or installation errors, making it difficult to remove, or even requiring cutting off the nut for replacement, which not only causes irreversible damage to the nut itself, but also causes certain damage to the corresponding connector. Therefore, it is urgent to design a nut that is easy to install and replace. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model provides a combined nut, including a sleeve and two semicircular rings forming a cylinder, one end of the sleeve is integrally provided with a flange ring, the two semicircular rings are coaxially slidably embedded in the sleeve and abut against the flange ring; the semicircular rings and the flange ring are fastened together by bolts; the inner walls of the two semicircular rings are provided with matching internal threaded portions; the inner diameter of the flange ring is not less than the outer diameter of the internal threaded portion.

[0005] Furthermore, an annular boss is provided on the inner wall of the semicircular ring close to one end of the flange ring, and the inner diameter of the annular boss is smaller than the inner diameter of the internal threaded portion.

[0006] Furthermore, the outer contour of the sleeve is one of a circle, a regular hexagon and an external spline shape.

[0007] Furthermore, an end surface of the sleeve away from the flange ring is flush with end surfaces of the two semicircular rings.

[0008] Furthermore, a gasket is provided between the flange ring and the two semicircular rings, and a plurality of top screw threads are evenly distributed along the circumference of the flange ring; the top screw threads are used to connect the external top screws and support the gasket, so that the sleeve is separated from the semicircular rings.

[0009] Furthermore, a matching rubber plug is provided in the top screw thread.

[0010] Compared with the prior art, the beneficial effect of the utility model is that by fixing the two semi-circular rings in the sleeve, when in use, the two semi-circular rings can be easily detached from the corresponding connecting parts by simply detaching the sleeve, and no cutting process is required. At the same time, it is also convenient to replace the two semi-circular rings, which facilitates the overall installation and disassembly and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] 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.

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] Example 1

[0022] For bolts or screws, see Figure 1 and Figure 2The utility model provides a combined nut, including a sleeve 1 and two semicircular rings 3 forming a cylinder, one end of the sleeve 1 is integrally provided with a flange ring 2, the two semicircular rings 3 are coaxially slidably embedded in the sleeve 1 and abut against the flange ring 2; the semicircular rings 3 and the flange ring 2 are fastened as a whole by bolts 4; the inner walls of the two semicircular rings 3 are provided with matching internal threaded parts; the inner diameter of the flange ring 2 is not less than the outer diameter of the internal threaded part.

[0023] Through the two semicircular rings 3, one or two can be replaced together without cutting the nut; the sleeve 1 with the flange ring 2 can fix the two semicircular rings 3 to ensure the axial force strength of the two semicircular rings 3. When the nut is stuck and needs to be disassembled, just loosen the bolt 4, slide the sleeve 1 out, and the two semicircular rings 3 can be easily separated from the corresponding connecting parts, thereby improving the convenience of using the nut.

[0024] The end surface of the sleeve 1 here that is away from the flange ring 2 is preferably flush with the end surfaces of the two semicircular rings 3, so as to further improve the connection stability with the corresponding connecting piece.

[0025] like Figure 4 As shown, the outer contour of the sleeve 1 can be a regular hexagon; Figure 5 As shown, the outer contour of the sleeve 1 may also be an external spline shape; the regular hexagon and the external spline shape are conducive to the installation of the utility model.

[0026] Example 2

[0027] For the screw with an optical axis, based on the above embodiment 1, as Figure 3 As shown, the utility model also provides a combined nut, specifically, an annular boss 31 is provided on the inner wall of the semicircular ring 3 close to one end of the flange ring 2, and the inner diameter of the annular boss 31 is smaller than the inner diameter of the internal thread part.

[0028] When in use, the optical axis portion of the screw rod passes through the annular boss 31 , and the end portion of the screw rod may abut against the annular boss 31 or leave a gap, which will not be described in detail.

[0029] Example 3

[0030] On the basis of the above-mentioned embodiment 1 or embodiment 2, Figure 6 and Figure 7 As shown, the utility model also provides a combined nut, specifically, a gasket 5 is provided between the flange ring 2 and the two semicircular rings 3, and a plurality of top screw threads 21 are evenly distributed along the circumference of the flange ring 2.

[0031] When it is inconvenient for the sleeve 1 to be detached from the semicircular ring 3, a matching top screw is used at the top screw thread 21. The top screw is alternately screwed between several top screw threads 21. The top screw can support the gasket 5, and the sleeve 1 moves relative to the semicircular ring 3 and detaches from the semicircular ring 3, thereby ensuring the disassembly of the nut and facilitating the replacement of the nut.

[0032] A matching rubber plug 22 may be provided in the top screw thread 21 to prevent the top screw thread 21 from being contaminated and blocked, thereby facilitating overall disassembly.

[0033] The utility model can be summarized in other specific forms that do not violate the spirit or main features of the utility model. Therefore, no matter from which point of view, the above embodiments of the utility model can only be regarded as an explanation of the utility model and cannot limit the utility model. The claims indicate the scope of the utility model, while the above description does not indicate the scope of the utility model. Therefore, any changes within the meaning and scope equivalent to the claims of the utility model should be considered to be included in the scope of the claims of the utility model.
