Description

Technical Field

[0001] This utility model relates to the field of nut structure technology, and more specifically, to a detachable and combinable nut. Background Technology

[0002] A nut is a common fastener, typically used in conjunction with a bolt or screw to achieve a mechanical connection through threaded engagement. It is widely used in machinery, building structures, automotive manufacturing, and electronic equipment.

[0003] Currently, after long-term use, nuts are prone to excessive wear on their internal threads, rendering them unusable. Usually, we replace the entire nut, but since the threaded portion occupies a small portion of the nut, replacing the entire nut can easily lead to cost waste.

[0004] Therefore, in view of this, the existing structure was studied and improved to provide a detachable and combinable nut, in order to achieve a more practical purpose. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figure 1 - Figure 4 A detachable and combinable nut, the combinable nut consisting of an upper cover 1, a hexagonal sleeve 2, a lower cover 3 and multiple inner sleeves 4 with internal threads;

[0034] Both the upper and lower ends of the hexagonal sleeve 2 are provided with external threaded openings 201. The upper cover 1 is threadedly connected to the external threaded opening 201 at the upper end of the hexagonal sleeve 2, and the lower cover 3 is threadedly connected to the external threaded opening 201 at the lower end of the hexagonal sleeve 2. Multiple slots 202 are provided on the inner side of the hexagonal sleeve 2. Multiple inner sleeves 4 with internal threads are stacked on top of each other and inserted into the interior of the hexagonal sleeve 2. Multiple locking blocks 401 are fixedly provided on the outer side of each inner sleeve 4 with internal threads. The locking blocks 401 are inserted into the corresponding slots 202.

[0035] See Figure 1 , Figure 2 Specifically, the upper cover 1 and the lower cover 3 have the same structure, and the upper cover 1 and the lower cover 3 are arranged symmetrically along the upper and lower axes.

[0036] This allows for easy interchangeability of the upper cover 1 and the lower cover 3, and if either the upper cover 1 or the lower cover 3 is damaged, it can be replaced with another upper cover 1 or lower cover 3, reducing the cost of nuts.

[0037] Specifically, the outer sides of the upper cover 1, the lower cover 3, and the hexagonal sleeve 2 all have the same hexagonal structure.

[0038] After assembling the combination nuts, it is easy to ensure that the upper and lower structures of the combination nuts are consistent, which makes it easier to rotate the combination nuts using tools such as hex wrenches.

[0039] Specifically, the outer side of the upper cover 1, the inner side of the lower cover 3, and the inner side of the inner sleeve 4 with internal threads are all circular structures with the same inner diameter.

[0040] When using bolts or screws to pass through the combination nut, it facilitates the smooth passage of bolts and screws. At the same time, the upper cover 1 and the lower cover 3 can restrict the inner sleeve 4 with internal threads. The upper cover 1, the lower cover 3, and the hexagonal sleeve 2 form a cavity structure, and the inner sleeve 4 with internal threads is restricted inside the cavity structure.

[0041] See Figure 1 , Figure 2 , Figure 3 Specifically, the external thread of the external threaded ring 201 and the internal thread of the inner sleeve 4 with internal thread have opposite helical directions.

[0042] Control the spiral directions of the two to be opposite. When rotating clockwise, the hexagonal sleeve 2 and the inner sleeve 4 with internal threads are tightened, while the upper cover 1 and the lower cover 3 are loosened.

[0043] Using this principle, when removing the combined nut, it is necessary to loosen the hexagonal sleeve 2 and the inner sleeve 4 with internal threads. At this time, the rotation direction is counterclockwise, while the upper cover 1 and the lower cover 3 are in a tightened state when rotated counterclockwise. At this time, the loosening operation can be carried out regardless of whether the wrench is stuck on the outside of the hexagonal sleeve 2 or the outside of the upper cover 1 or the lower cover 3, which improves the convenience of removing the nut.

[0044] Meanwhile, depending on the needs of the bolts or screws, an inner sleeve 4 with an internal thread of the corresponding pitch can be selected, which improves the applicability of the combination nut to different bolts or screws.

[0045] See Figure 2 , Figure 4 Specifically, the length of the hexagonal sleeve 2 is an integer multiple of the length of the inner sleeve 4 with internal threads.

[0046] According to the needs of use, a combination nut of appropriate length can be selected. At the same time, the cavity structure formed by the upper cover 1, the lower cover 3, and the hexagonal sleeve 2 can ensure that a sufficient number of internally threaded inner sleeves 4 can be inserted, and prevent the internally threaded inner sleeves 4 from shaking inside the cavity.

[0047] See Figure 2 , Figure 4 , Figure 4 Specifically, the number of slots 202 opened on the inner side of the same hexagonal sleeve 2 is four, and the four slots 202 are distributed in a cross-shaped structure.

[0048] The same inner sleeve 4 with internal threads is provided with four locking blocks 401, and the four locking blocks 401 are distributed in a cross shape.

[0049] Working principle:

[0050] The combination nut consists of an upper cover 1, a hexagonal sleeve 2, a lower cover 3, and multiple inner sleeves 4 with internal threads. When using it, select the appropriate length of combination nut according to the needs of use.

[0051] At this point, take the corresponding length of hexagonal sleeve 2, and then, using the external threaded ring 201, screw the lower cover 3 into the bottom of the hexagonal sleeve 2. Place the corresponding number of internally threaded inner sleeves 4 into the hexagonal sleeve 2. At this time, pay attention to the locking block 401 being inserted into the locking slot 202. Then, screw the upper cover 1 into the top of the hexagonal sleeve 2. In this way, the assembly and use of the combination nut can be completed.

[0052] After a certain period of use, if the internal threads of the combination nut become worn or some parts of the combination nut become unusable, the worn or unusable parts can be removed and replaced, thereby reducing the replacement cost of the combination nut.

[0053] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
