Description

Technical Field

[0001] The utility model relates to the technical field of U-shaped bolts, in particular to a magnetic U-shaped bolt used for precise connection. Background Art

[0002] U-bolts, also known as riding bolts, are non-standard parts. They are named after their U-shaped shape. They have threads at both ends that can be combined with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs of cars. Because the way they fix objects is like a person riding on a horse, they are called riding bolts. Magnetic U-bolts are widely used in the field of precision connection. They not only have the basic functions of U-bolts, that is, they can provide a stable connection effect through their unique U-shaped design, but also have magnetism, which makes the operation more convenient and efficient.

[0003] For example, the Chinese patent "CN216044893U" discloses a U-bolt with magnetism for precision connection, which proposes: In view of the problem that the general U-bolt has a single design structure and function, a small scope of application, and low safety performance of the connecting hardware, the following scheme is proposed, which includes a bolt body, a horizontal cavity is provided in the horizontal section of the bolt body, and a magnetic core 1 is slidably arranged in the horizontal cavity, and a limit pin is slidably arranged at both ends of the horizontal cavity, and the limit pin is in close contact with the magnetic core 1, and the two vertical sections of the bolt body are provided with vertical cavities, and a magnetic core 2 is slidably arranged in the two vertical cavities, and a sealing stud is threadedly arranged at one end of the vertical cavity away from the horizontal cavity. The structure is novel, the functional structure of the U-bolt is optimized, the safety of the connection is improved, and it is suitable for promotion.

[0004] It can be seen from the above-mentioned device that although the above-mentioned method of providing a magnetic core inside the U-shaped bolt to increase the magnetism is proposed, the current technical solution still has the following shortcomings:

[0005] The existing magnetic U-bolts always have the attached magnetism, which cannot be eliminated by removing the internal magnets. In normal use, the nuts are difficult to rotate due to the influence of magnetism. When used in conjunction with non-magnetic nuts, precise connection and fixation cannot be achieved, and they are prone to loosening after long-term use. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides a magnetic U-bolt for precise connection. The magnetic block inside the U-bolt is very convenient to install and remove. After the nut is used to fix it, the nut is precisely connected to the hollow screw rod through magnetism to prevent loosening after long-term use. The utility model solves the problem that the existing magnetic U-bolt has the advantages of always having the attached magnetism and being unable to cancel the magnetism by removing the internal magnet. During normal use, the nut is difficult to rotate due to the influence of the magnetism. When used in conjunction with a nut that does not have magnetism, precise connection and fixation cannot be achieved and the nut is prone to loosening after long-term use.

[0028] 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.

[0029] See also Figure 1-2 A magnetic U-bolt for precision connection includes a U-bolt 1. Hollow screws 11 are arranged on both sides of the U-bolt 1. A mounting groove 12 is arranged inside the hollow screw 11. The hollow screw 11 is provided with a mounting groove 12, which is a specially designed space for installing a magnetic block 21. This design enables the bolt to have a magnetic function while maintaining its structural integrity. A mounting component 2 is arranged inside the mounting groove 12.

[0030] See also Figure 2 The mounting assembly 2 includes a magnetic block 21, which can be movably installed inside the hollow screw 11. The magnetic block 21 is the core part of the mounting assembly 2 and has strong magnetism, so that the U-bolt 1 can be more conveniently adsorbed and fixed to the metal part. The magnetic block 21 is designed to be movably installed inside the hollow screw 11. This design makes it possible for the magnetic block 21 to be easily installed or removed as needed, thereby increasing the flexibility of use. A supporting spring 24 is arranged inside the hollow screw 11, and a mounting plate 22 is fixedly connected to the outer wall of the supporting spring 24. A plurality of limiting rods 23 are arranged in a ring matrix on the outer wall of the mounting plate 22. A plurality of J-shaped slots 25 are opened on the outer wall of the hollow screw 11, and a plurality of mounting plates 22 are movably installed inside the J-shaped slots 25. The limiting rods 23 play a guiding and limiting role to ensure that the mounting plate 22 can only move along a predetermined trajectory. The limiting rods 23 are arranged in a trapezoidal shape, and the bending part of the J-shaped slot 25 is also arranged in a trapezoidal shape. The inclined sides of the limiting rods 23 are aligned with the inclined sides of the J-shaped slot 25. The bending parts of the limiting rods 23 and the J-shaped slots 25 both adopt a trapezoidal design. This design makes it possible for the limiting rods 23 to smoothly transition to the next slot part when they move to the bending part of the J-shaped slot 25, thereby avoiding the occurrence of a jamming phenomenon.

[0031] See also Figure 3-4The outer wall of the hollow screw 11 is provided with a connecting assembly 3, and the connecting assembly 3 includes a nut 31, and the nut 31 is installed on the hollow screw 11 through surface thread meshing. The outer wall of the nut 31 is provided with a plurality of slide grooves, and an active slide plate 32 is movably installed in the slide groove of the nut 31. Both sides of the active slide plate 32 are provided with transverse sliders 33, and the transverse sliders 33 are movably installed in the small slide grooves provided to limit the movement of the active slide plate 32. The inner side of the outer wall of the active slide plate 32 is provided with an inclined edge, and the inclined edge of the active slide plate 32 is fitted with a passive slide plate 34, and the passive slide plate 3 The passive slide 34 is movably installed in the slide groove opened inside the nut 31. Vertical slides 35 are arranged on both sides of the passive slide 34. The vertical slides 35 are arranged inside the two vertical slide grooves opened inside the nut 31. A tension spring 36 is fixedly connected below the vertical slide 35. The passive slide 34 is connected to the nut 31 through the tension spring 36, which provides the power for the passive slide 34 to reset. A magnetic plate 37 is arranged below the passive slide 34. The magnetic plate 37 and the magnetic block 21 attract each other. The magnetic plate 37 is arranged below the passive slide 34 and attracts each other with the magnetic block 21. When the active slide 32 moves, the distance between the magnetic block 21 and the magnetic plate 37 can be adjusted through the linkage of the passive slide 34 and the magnetic plate 37, thereby controlling the adsorption force of the bolt.

[0032] Working principle: First, when installing the U-bolt 1, press the magnetic blocks 21 on both sides. The magnetic blocks 21 on both sides drive the mounting plate 22 to move downward after being pressed. The limiting rod 23 slides from the short section of the J-shaped slide groove 25 to the long section through the inclined edge. Then the two magnetic blocks 21 are bounced up and taken out. After taking them out, the U-bolt 1 is installed, and the object and the U-bolt 1 are tightened and fixed by rotating the nut 31. When the tightening is completed, the active slide plate 32 protruding from the outer wall of the nut 31 is squeezed by the surface of the object during tightening, and the active slide plate 32 moves toward the inside of the nut 31. When the active slide plate 32 moves, the passive slide plate 34 is squeezed by the inclined edge, driving the passive slide plate 34 to move downward. After the passive slide plate 34 moves downward, the magnetic plate 37 arranged under the passive slide plate 34 is close to the inner wall of the nut 31.

[0033] Secondly, after the nut 31 is tightened, the magnet 21 is placed into the installation groove 12. After placement, the magnet 21 is pressed so that the magnet 21 drives the internal installation plate 22 to be squeezed inward. When the installation plate 22 is squeezed inward, the limit rod 23 set on its outer wall cooperates with the inclined edge of the J-shaped slide 25 at the bend through the trapezoidal inclined edge, and moves from the long section of the J-shaped slide 25 to the short section by pressing downward. At this time, the magnet 21 is completely installed into the installation groove, and the limit rod 23 is always in the short section of the J-shaped slide 25 through the force of the support spring 24 to prevent the magnet 21 from being ejected and falling off. After the installation is completed, the magnet 21 and the magnetic plate 37 are precisely connected together by the attraction force to firmly fix the object. This connection method not only enhances the fixing effect of the U-bolt, but also improves the overall stability and reliability.
