Description

Technical Field

[0001] This utility model relates to the field of nut clamp technology, and in particular to a high-strength nut clamp for use with bolts. Background Technology

[0002] A textile machine, also known as a spinning machine, loom, or cotton spinning machine, was originally a human-powered loom. A textile machine is a tool used to process raw materials such as thread, silk, and hemp into yarn and then weave it into fabric. During operation, textile machines generate high-frequency vibrations, therefore, the fasteners used in textile machines need to be specially modified for this high-frequency vibration environment.

[0003] Chinese Patent Publication No. CN116753229A discloses a high-strength nut clamp for use with bolts, used to connect automotive metal panels and body injection molded parts. It includes a first clamping plate, a second clamping plate, a connecting plate, a locking nut, and a locking tongue. The first clamping plate is located below the second clamping plate, and its end is connected to the second clamping plate via the connecting plate to form a groove for accommodating the automotive metal panel and body injection molded parts. The locking nut is movably connected to the second clamping plate and is located on the side away from the first clamping plate. One end of the locking tongue is located on the upper surface of the first clamping plate, and the other end is suspended and faces towards the side closer to the second clamping plate. The bolt extends sequentially from the first clamping plate, the locking tongue, the automotive metal panel, the body injection molded part, and the second clamping plate before being fixed to the locking nut. This nut clamp achieves the purpose of fastening the installed parts through over-clamping, bolt locking, and the springback properties of metal.

[0004] The above-mentioned device increases the elastic compressive force on the side of the nut through the structure of the clamping plate, thereby reducing the risk of the nut loosening. However, in actual use, the compressive force on the side of the nut will increase the resistance to rotation of the nut on the one hand, and the lateral compressive force will also generate the tangential component force of the thread on the other hand, thereby increasing the risk of the nut loosening after long-term use. Therefore, the above-mentioned device is generally not very effective in locking and fixing the nut. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] The purpose of this invention is to address the technical problems existing in the background art. This invention proposes a high-strength nut clamp for use with bolts. This invention can effectively improve the loosening effect of nuts under high-frequency vibration environment, thereby preventing problems such as parts loosening during long-term continuous use of textile machines.

[0007] This utility model proposes a high-strength nut clamp for use with bolts, including a U-shaped part with a through hole through which a bolt is inserted. An elastic component is connected to one side of the U-shaped part, and a through hole is provided at the center of the elastic component. One end of the bolt contacts the elastic component and passes through the center of the elastic component, and a nut is threaded to the other end of the bolt.

[0008] The U-shaped part has an annular groove on the side away from the elastic component. The bottom of the inner wall of the annular groove has several circumferentially distributed rotational locking parts A. The nut has an annular boss on one side. The side of the annular boss away from the nut is connected to several circumferentially distributed rotational locking parts B.

[0009] By adopting the above technical solution, this solution can effectively reduce the risk of the nut loosening during use by locking the nut with a locking component.

[0010] Preferably, the inner wall of the U-shaped part is connected to a pad, and the U-shaped part is provided with a mounting plate, with the two sides of the mounting plate contacting and pressing against the pad.

[0011] By adopting the above technical solution, this solution allows the pads to be replaced according to different usage scenarios and mounting plates of different thicknesses, thereby enabling the device to be compatible with textile machine structures of different models and sizes. The mounting plate represents the mechanical structure in the textile machine that needs to be fastened.

[0012] Preferably, the U-shaped component is a metal U-shaped component, and the U-shaped component has a metal restorable elasticity.

[0013] By adopting the above technical solution, this solution can bend elastically to a certain extent through the metal U-shaped structure, thereby making the clamping between the pad and the mounting plate tighter, thus ensuring the fastening effect of this device.

[0014] Preferably, the elastic component includes a spring housing connected to the U-shaped component, a plurality of circumferentially distributed springs are connected to the bottom of the inner wall of the spring housing, and a spring plate is connected to the top of the spring, with the top of the spring plate in contact with the bolt.

[0015] By adopting the above technical solution, this solution can lift the bolt in a static state through the structure of the spring plate, thereby driving the nut to make tight contact with the rotating locking part A through the bolt, ensuring the stability of the locking effect while facilitating subsequent unlocking.

[0016] Preferably, both the spring housing and the spring plate are annular structures, and the diameter of the central through hole in the spring housing and the spring plate is larger than the diameter of the through hole on the side of the U-shaped component.

[0017] By adopting the above technical solution, this solution, through the spring plate structure with a larger diameter, can ensure that the device can effectively accommodate fasteners of different sizes, thereby improving the compatibility of the device.

[0018] Preferably, the rotational locking member A and the rotational locking member B correspond one-to-one, and the rotational locking member A and the rotational locking member B engage with each other.

[0019] By adopting the above technical solution, this solution can effectively improve the fastener locking stability of this device through the combination of the rotating locking component A and the rotating locking component B.

[0020] Preferably, the width of the annular boss is smaller than the width of the inner wall of the annular groove, and the side of the nut with the annular boss contacts the side of the U-shaped part.

[0021] By adopting the above technical solution, this solution can ensure that the nut and the side of the U-shaped part are in full contact through the combination of the annular boss and the annular groove.

[0022] Preferably, the surface of the pad is provided with a buffer layer, the mounting plate is provided with through holes, and the bolt passes through the mounting plate.

[0023] By adopting the above technical solution, this solution can protect the surface of the mounting plate through the buffer layer of the pad.

[0024] In summary, this utility model has at least one of the following beneficial effects:

[0025] This device can effectively improve the stability of fastening for mechanical equipment that generates high-frequency vibrations during operation. Compared with traditional devices, this device uses a combination structure of rotating locking parts to lock the nut, thereby reducing the risk of accidental loosening. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0036] Example 1

[0037] like Figures 1-7 As shown, in order to solve the existing problems, this utility model discloses a high-strength nut clamp for use with bolts, including a U-shaped part 1. The U-shaped part 1 has a through hole, and a bolt 4 is inserted through the through hole. An elastic component 6 is connected to one side of the U-shaped part 1. The elastic component 6 has a through hole at its center. One end of the bolt 4 contacts the elastic component 6 and passes through the center of the elastic component 6. The other end of the bolt 4 is threaded with a nut 5.

[0038] The inner wall of the U-shaped part 1 is connected to a pad 2, and the U-shaped part 1 is provided with a mounting plate 3 inside. The two sides of the mounting plate 3 are respectively in contact with and pressed against the pad 2.

[0039] Furthermore, the U-shaped component 1 is a metal U-shaped component, and the U-shaped component 1 has a metal restorable elasticity.

[0040] The elastic component 6 includes a spring housing 601 connected to the U-shaped component 1. A plurality of springs 602 distributed in a circular pattern are connected to the bottom of the inner wall of the spring housing 601. A spring plate 603 is connected to the top of the spring 602. The top of the spring plate 603 is in contact with the bolt 4.

[0041] Furthermore, both the spring housing 601 and the spring plate 603 are annular structures, and the diameter of the central through hole of the spring housing 601 and the spring plate 603 is larger than the diameter of the through hole provided on the side of the U-shaped part 1.

[0042] The specific working principle is as follows: By inserting the textile machine structure that needs to be fastened into the U-shaped part 1, the device can be fastened. When the mounting plate 3 is inside the U-shaped part 1, the clamping compatibility of the device can be effectively improved by replacing the appropriate size pad 2, and the accuracy of the device's fastening adjustment can be improved. After the appropriate pad 2 is installed, the bolt 4 is inserted and passes through the elastic part 6 and the through hole on the side of the U-shaped part 1. The nut 5 is then threaded onto the other end of the bolt 4, at which point the nut 5 is in a loose state.

[0043] Example 2

[0044] like Figures 1-7 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the above embodiment 1, the high-strength nut clamp for use with bolts further includes: an annular groove 7 is provided on the side of the U-shaped part 1 away from the elastic part 6, and a plurality of circumferentially distributed rotational locking parts A8 are provided at the bottom of the inner wall of the annular groove 7; an annular boss 9 is provided on one side of the nut 5, and a plurality of circumferentially distributed rotational locking parts B10 are connected to the side of the annular boss 9 away from the nut 5;

[0045] Furthermore, the rotational locking member A8 corresponds one-to-one with the rotational locking member B10, and the rotational locking member A8 and the rotational locking member B10 engage with each other;

[0046] Furthermore, the width of the annular boss 9 is smaller than the width of the inner wall of the annular groove 7, and the side of the nut 5 with the annular boss 9 contacts the side of the U-shaped part 1;

[0047] Specifically, the surface of the pad 2 is provided with a buffer layer, the mounting plate 3 is provided with a through hole, and the bolt 4 passes through the mounting plate 3.

[0048] The specific working principle is as follows: when the bolt 4 is inserted and the nut 5 is pre-installed on the bolt 4, the bolt 4 is pressed down, thereby squeezing the spring plate 603 through the bolt 4 cap. At this time, the spring 602 inside the spring housing 601 is in a compressed state. Then, the nut 5 is rotated so that the nut 5 is close to the side of the U-shaped part 1. During the rotation of the nut 5, the annular protrusion 9 on the side of the nut 5 extends into the annular groove 7 on the side of the U-shaped part 1.

[0049] As nut 5 rotates, it presses against the side of U-shaped part 1. At this time, the rotation locking parts A8 and B10 come into contact with each other, preventing nut 5 from rotating further. Then, bolt 4 is loosened, and under the action of spring 602, bolt 4 springs upward. The springing bolt 4 makes the nut 5 fit more tightly against the side of U-shaped part 1. At this time, the rotation angle of nut 5 can be finely adjusted, so that the rotation locking parts A8 and B10 engage with each other, thus achieving the locking effect of nut 5. At this time, due to the lifting effect of spring 602, it is ensured that nut 5 is always in a state of pressing against the side of U-shaped part 1, ensuring the stability of the engagement between rotation locking parts A8 and B10.

[0050] When this device needs to be unlocked, the bolt 4 must be pressed first to separate the rotating locking part A8 from the rotating locking part B10. Then, the nut 5 is rotated so that it rotates relative to the bolt 4, thereby achieving the unlocking effect.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
