Technical Field

[0001] This utility model relates to the field of nut bracket technology, and in particular to a hexagonal nut bracket. Background Technology

[0002] A hexagonal nut bracket is a device used to assist in fixing and installing hexagonal nuts.

[0003] In the process of assembling mechanical components, when tightening a hexagonal nut to a certain working torque, a wrench is needed to work together with another wrench. One wrench is used to fix the hexagonal nut, and then the other wrench is used to tighten the bolt, thereby completing the assembly of the component.

[0004] However, tightening wrenches require a certain amount of operating space, which makes them difficult to operate in confined spaces, resulting in low efficiency and complex assembly of parts.

[0005] Therefore, we provide a hexagonal nut bracket. Utility Model Content

[0020] 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.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0022] Example: A hexagonal nut bracket, such as Figures 1-6 As shown, the assembly includes a nut 31, the corners of which slide against the inner wall of a limiting groove 41. The shape of the limiting groove 41 corresponds to the shape of the corners of the nut 31, allowing the nut 31 to be quickly and blindly pressed into the locking cylinder 4 and accurately aligned with the limiting groove 41 with a slight rotation. Simultaneously, when the bolt 3 is tightened, the limiting groove 41 limits the nut 31, preventing it from rotating. This achieves convenient and efficient assembly. The locking cylinder 4 is sleeved on the outside of the nut 31. The upper surface of the fixed cylinder 4 is fixedly connected to the inside of the bracket base plate 1. The upper surface of the locking cylinder 4 is threaded with a bolt 3, one end of which extends into the inside of the locking cylinder 4. The outer side of the locking cylinder 4 is fitted with a bracket upper frame 2. The lower surface of the bracket upper frame 2 is attached to the bracket base plate 1. The locking cylinder 4 has a moving groove 433 inside. The upper half of the inner wall of the moving groove 433 has a reset groove 4331 on both sides. A reset spring 435 is fixedly installed on the inner wall of the reset groove 4331. The reset spring 435 can pull the fixed block 432 to reset. A slider 434 is fixedly installed on the inner wall of the reset spring 435 away from the reset groove 4331. The slider 434 slides inside the reset groove 4331. Fixing rods 4341 are fixedly installed on both sides of the slider 434. The outer side of the fixing rods 4341 is fixedly connected to the inside of the fixing block 432. Several limiting grooves 41 are provided on the inner wall of the locking cylinder 4. A contraction groove 42 is provided on the inner wall of the locking cylinder 4. A spring 443 is fixedly installed on the inner wall of the contraction groove 42. The other end of the spring 443 is fixedly connected to one end of the fixing frame 43. The fixing frame 43 slides inside the contraction groove 42. Spring 443 can reset the fixed frame 43, ensuring that when the nut 31 enters the locking cylinder 4, the spring 443 can contract, allowing the fixed frame 43 to enter the contraction groove 42. After the nut 31 enters the locking cylinder 4, the spring 443 can reset, allowing the fixed frame 43 to support the nut 31 and prevent the nut 31 from falling off. The distance between the upper side of the fixed frame 43 and the inner wall of the locking cylinder 4 is only enough to ensure the installation of the nut 31, thus ensuring the accurate installation position of the nut 31 and preventing inaccurate installation of the nut 31 from causing loose installation. Both the fixed frame 43 and the flip plate 44 are arc-shaped at the ends away from the inner wall of the shrinkage groove 42. The arc-shaped end of the flip plate 44 is longer than the arc-shaped end of the fixed frame 43, so that when the bolt 3 rotates downward, it can contact the flip plate 44, ensuring the rotation of the flip plate 44 while the fixed frame 43 remains stable. The ends of the fixed frame 43 and the flip plate 44 away from the inner wall of the shrinkage groove 42 extend into the interior of the locking cylinder 4. The fixed frame 43 has a rotating shaft 441 fixedly installed on opposite sides inside. The rotating shaft 441 and the flip plate 44 are fixedly connected to both ends of a torsion spring. The torsion spring is existing technology and will not be described in detail here, nor is it shown in the figure. The flip plate 44 is rotatably connected to the outside of the rotating shaft 441. The flip plate 44 can convert the downward pressure of the bolt 3 into a clamping force on the nut 31, so that the greater the downward force, the greater the clamping force. The rotating state of the flip plate 44 is a slight rotation, so that it can contact the driving block 431, causing the driving block 431 to move upward. Therefore, the downward movement of the bolt 3 can push the flip plate 44. The rotation of plate 44 causes a drive block 431 to be installed at one end of the flip plate 44. The drive block 431 slides inside the moving groove 433 on its outer side. A fixing block 432 is installed at the upper end of the drive block 431. There are several fixing blocks 432, which are randomly distributed and have different distances from the corners of the nut 31. This can prevent the fixing blocks 432 from being unstable due to the random installation of the nut 31. The fixing blocks 432 have a telescopic effect and can adapt to the expansion and contraction of the nut 31 with different contact surfaces, ensuring the stable operation of the fixing blocks 432. The contact surface between the fixing blocks 432 and the nut 31 is made of rubber, which can increase friction and ensure stable contact. At the same time, it can be plasticized according to the shape of the contact surface, further ensuring the stability of the contact. It also clamps the nut 31 to prevent the nut 31 from sliding between the nut 31 and the limiting groove 41 due to excessive torque. It also prevents the nut 31 from loosening due to vibration during use. One end of the fixing block 432 extends into the locking cylinder 4.

[0023] Working principle: When assembling the parts begins, the nut 31 is first pressed into the locking cylinder 4 through the limiting groove 41. The nut 31 exerts a pushing force on the flip plate 44 and the fixing frame 43, causing the spring 443 to contract. The flip plate 44 and the fixing frame 43 then enter the shrinkage groove 42. The nut 31 moves into the locking cylinder 4, the spring 443 unfolds, and the flip plate 44 and the fixing frame 43 move to the outside of the shrinkage groove 42. At this time, the bolt 3 is tightened, and the bolt 3 moves into the locking cylinder 4 through the upper frame 2 of the bracket and the bottom plate 1 of the bracket. One end of bolt 3 exerts a pressing force on one end of flip plate 44, causing flip plate 44 to start rotating. The other end of flip plate 44 contacts the bottom end of drive block 431, and flip plate 44 pushes drive block 431 upward. Drive block 431 moves upward and exerts a thrust on one end of fixed block 432, causing fixed block 432 to start moving. Slider 434 slides inside reset groove 4331, reset spring 435 unfolds, and one end of fixed block 432 contacts the surface of nut 31, thus completing the fastening between bolt 3 and nut 31.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
