Description

Technical Field

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

[0002] Nuts, also known as bolt nuts, are parts that are screwed together with bolts or screws to provide a fastening effect. They are an essential component in manufacturing machinery.

[0003] During use, due to environmental factors, the internal threads of the nut may rust after prolonged use. In this case, disassembling and replacing the nut becomes extremely difficult, resulting in a decrease in the overall stability of the device during use.

[0004] To overcome the aforementioned shortcomings, existing technology (Chinese patent publication number CN216131219U, application date 2021-11-02) provides a detachable nut. The male nut lobe has a male threaded groove on its inner wall, and the female nut lobe has a female threaded groove on its inner wall to form a complete threaded groove with the male threaded groove. A male inner stop block is integrally fixed to one end of the male threaded groove on the inner wall of the male nut lobe, and a female inner stop block is integrally fixed to the inner wall of the female nut lobe at a position corresponding to the male inner stop block. This improves the ease of installation.

[0005] The above-mentioned mechanism uses different blocks to cooperate with each other to connect and fix the two nuts. However, in actual use, the tenon and mortise connection alone may not be strong enough, affecting the overall stability when connecting. Utility Model Content

[0006] The purpose of this utility model is to provide a detachable nut to solve the problem mentioned in the background art that, due to environmental factors, the internal threads of the nut may corrode after long-term use, making disassembly and replacement of the nut extremely difficult and causing a decrease in the overall stability of the device during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detachable nut, including a left nut, wherein a right nut is engaged with one side of the left nut;

[0008] Two limiting blocks are provided on one side of the top of the left nut. The bottom of the limiting block is provided with a splitting mechanism for disassembling the left nut and the right nut. The splitting mechanism includes a fixing rod, which is fixedly connected to the bottom of the limiting block. A fixing hole matching the fixing rod is opened on one side of the top of the right nut.

[0009] Both the left and right nuts are provided with wear-resistant layers on their outer sides, and the wear-resistant layers are provided with wear-resistant mechanisms to increase wear resistance and anti-slip performance.

[0010] Furthermore, two limiting grooves matching the limiting block are provided on one side of the top of the right nut, and the limiting block and the limiting groove are engaged and connected to the tops of the left nut and the right nut.

[0011] Furthermore, the bottom end of the fixing rod passes through and extends below the right nut, and a fixing block is threadedly connected to the outer side of the fixing rod, the fixing block being located at the bottom end of the right nut.

[0012] Furthermore, the wear-resistant mechanism includes a rust-proof layer, which is fixedly connected to the outside of the left nut and the right nut.

[0013] Furthermore, an anti-slip mechanism is provided on the inner side of the wear-resistant layer on the outer side of the anti-rust layer. The anti-slip mechanism includes an elastic layer, which is fixedly connected to the outer side of the anti-rust layer. The elastic layers are evenly distributed on the outer side of the anti-rust layer, and the outer side of the elastic layer is in contact with the inner side of the wear-resistant layer.

[0014] Furthermore, a support block is fixedly connected to the inner side of the elastic layer, and the height of the support block is equal to the height of the elastic layer.

[0015] Furthermore, one side of the support block is connected to the outer side of the anti-rust layer, and the support block is symmetrical about the vertical central axis of the anti-rust layer.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. When the nut needs to be removed, the fixing block is rotated to separate the fixing block from the fixing rod. Then, the left nut is moved upward to separate the fixing rod from the fixing hole, thereby separating the limit between the left and right nuts. This makes it easier to separate the nuts in case of corrosion and jamming, and facilitates better visibility for nut replacement.

[0018] Furthermore, during nut installation, by moving the fixing rod downwards and engaging it with the fixing hole, the limiting block on the left nut side and the limiting groove at the top of the right nut can engage with each other, thus providing basic positioning for the left and right nuts and preventing misalignment before the left and right nuts are connected.

[0019] Furthermore, by utilizing the cooperation of the limiting block and the limiting groove, the basic limiting of the fixing rod and the fixing hole is achieved. Then, the fixing block can be used to reinforce the fixing rod and the fixing hole from below the right nut, increasing the stability of the connection between the fixing rod and the fixing hole, thereby effectively preventing the left nut and the right nut from coming loose.

[0020] 2. By setting the anti-rust layer on the outside of the left and right nuts, the left and right nuts are prevented from being corroded by moisture and rusted. At the same time, since the anti-rust layer is set inside the wear-resistant layer, the wear-resistant layer can effectively extend the service life of the anti-rust layer.

[0021] Furthermore, by utilizing the elastic layer and support block inside the wear-resistant layer and rust-proof layer, the left and right nuts can be made to increase their anti-slip performance when the wear-resistant layer is squeezed and screwed, thus preventing them from slipping off during screwing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figures 1-4The technical solution shown addresses the problem that, due to environmental factors, the internal threads of nuts corrode after prolonged use, making disassembly and replacement of the nuts extremely difficult and causing a decrease in the overall stability of the device during use. This detachable nut discloses a disassembly mechanism, including a left nut 1, with a right nut 2 engaged on one side of the left nut 1. Two limiting blocks 3 are provided on one side of the top of the left nut 1, and a disassembly mechanism for disassembling the left nut 1 and right nut 2 is provided at the bottom of the limiting blocks 3. The disassembly mechanism includes a fixing rod 5, which is fixedly connected to the bottom of the limiting blocks 3, and a fixing hole 7 matching the fixing rod 5 is provided on one side of the top of the right nut 2.

[0031] In this example, when the nut needs to be removed, the fixing block 8 is rotated to separate the fixing block 8 from the fixing rod 5. Then, the left nut 1 is moved upward to separate the fixing rod 5 from the fixing hole 7, thereby separating the limit between the left nut 1 and the right nut 2. This makes it easier to separate the nut in case of rust and jamming, and facilitates better visibility for nut replacement on the device.

[0032] When installing the nuts, the fixing rod 5 is moved downward and engaged with the fixing hole 7, so that the limiting block 3 on the left nut 1 side and the limiting groove 4 opened at the top of the right nut 2 can engage with each other, thus providing basic positioning for the left nut 1 and the right nut 2 and preventing misalignment before the left nut 1 and the right nut 2 are connected.

[0033] Example 2: Figure 2 and Figure 4 The technical solution shown addresses the problem of loosening that easily occurs after the fixing rod 5 and fixing hole 7 are connected: the detachable nut discloses a limiting mechanism. Two limiting grooves 4 that match the limiting block 3 are opened on one side of the top of the right nut 2, and the limiting block 3 and the limiting grooves 4 are engaged and connected to the top of the left nut 1 and the right nut 2. The bottom end of the fixing rod 5 passes through and extends to the bottom of the right nut 2, and a fixing block 8 is threadedly connected to the outside of the fixing rod 5. The fixing block 8 is located at the bottom of the right nut 2.

[0034] In this example, the basic positioning of the fixing rod 5 and the fixing hole 7 is achieved by the cooperation of the limiting block 3 and the limiting groove 4. Then, the fixing block 8 can be used to reinforce the fixing rod 5 and the fixing hole 7 from below the right nut 2, increasing the stability of the connection between the fixing rod 5 and the fixing hole 7, thereby effectively preventing the left nut 1 and the right nut 2 from becoming loose.

[0035] Example 3: Figure 2 , Figure 5 and Figure 6The technical solution shown addresses the problem of weakened anti-slip and wear-resistant performance of nuts due to prolonged exposure to external conditions during use. This detachable nut discloses a wear-resistant mechanism. Wear-resistant layers 6 are provided on the outer sides of both the left nut 1 and the right nut 2. The wear-resistant layer 6 contains a wear-resistant mechanism to enhance wear resistance and anti-slip performance. This mechanism includes a rust-proof layer 9, which is fixedly connected to the outside of the left nut 1 and the right nut 2. An anti-slip mechanism is provided on the inner side of the wear-resistant layer 6 outside the rust-proof layer 9. This anti-slip mechanism includes an elastic layer 10, which is fixedly connected to the outside of the rust-proof layer 9. The elastic layers 10 are evenly distributed on the outside of the rust-proof layer 9, and their outer sides are in contact with the inner side of the wear-resistant layer 6. A support block 11 is fixedly connected to the inner side of the elastic layer 10, with the height of the support block 11 equal to the height of the elastic layer 10. One side of the support block 11 is connected to the outer side of the rust-proof layer 9, and the support block 11 is symmetrical about the vertical central axis of the rust-proof layer 9.

[0036] In this example, the anti-rust layer 9 is set on the outside of the left nut 1 and the right nut 2, thereby preventing the left nut 1 and the right nut 2 from being corroded by moisture and rusting. At the same time, since the anti-rust layer 9 is set inside the wear-resistant layer 6, the wear-resistant layer 6 can effectively extend the service life of the anti-rust layer 9.

[0037] By utilizing the elastic layer 10 and support block 11 inside the wear-resistant layer 6 and the rust-proof layer 9, a certain amount of elasticity can be added to the left nut 1 and right nut 2 when the wear-resistant layer 6 is squeezed and screwed, so that the left nut 1 and right nut 2 can have a more stable anti-slip effect and avoid the left nut 1 and right nut 2 from slipping off when being screwed.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
