Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically a square nut used for connecting with U-shaped steel. Background Technology

[0002] U-shaped steel is widely used in many fields such as construction and machinery manufacturing due to its unique structure and excellent mechanical properties. In practical applications, it is often necessary to fix various components to U-shaped steel using bolts and nuts. Square nuts, as a commonly used connector, play an important role in such connection scenarios.

[0003] Traditional square nuts, mostly rectangular or square in structure, present numerous inconveniences when used with U-shaped steel. During installation and tightening, the lack of effective anti-rotation measures in traditional nuts means they rotate synchronously with the bolt. This not only significantly impacts installation efficiency, prolongs the construction period, and increases labor costs, but also results in poor structural stability after installation and commissioning. Affected by equipment vibration and external environmental factors, the nuts are prone to loosening, leading to reduced reliability of the connection between the fastened component and the U-shaped steel, potentially causing safety hazards and affecting the normal operation and service life of the entire system.

[0004] Therefore, developing a new type of nut that can effectively solve the problems existing when connecting traditional square nuts with U-shaped steel has become an urgent technical challenge in this field. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a square nut for connection with U-shaped steel.

[0006] The technical solution adopted by this utility model is: a square nut for connecting with U-shaped steel, including a nut body, a threaded hole that runs vertically through the middle of the nut body, fitting grooves symmetrically arranged on both sides of the nut body, elastic grooves arranged on the upper and lower sides of the fitting grooves, and the fitting grooves are interference fit with the stepped plate on the opening of the U-shaped steel.

[0007] Furthermore, the nut body is provided with a weight reduction groove, which is connected to the elasticity enhancement groove.

[0008] Furthermore, a reinforcing column is provided inside the weight-reducing groove, and the reinforcing column has a cross-shaped structure.

[0009] Furthermore, the reinforcing column is fixed to the nut body by bolts.

[0010] Furthermore, the opening of the fitting groove is chamfered on both sides.

[0011] Furthermore, thickening rings are provided on the upper and lower end faces of the threaded hole, and the thickening rings are concentrically arranged with the threaded hole.

[0012] Furthermore, the thickness of the thickening ring is 0.1-0.5 mm.

[0013] Furthermore, the outer circumferential array of the thickened ring has several wedge-shaped plates.

[0014] The beneficial effects of this utility model are:

[0015] 1. Improved Installation Efficiency: The square nut of this patent features symmetrically arranged fitting grooves on both sides, which are interference-fitted with the stepped plate on the U-shaped steel opening. During installation, this tight fit effectively prevents the nut from rotating synchronously with the bolt. Installers do not need to spend extra effort to fix the nut, allowing for quick bolt tightening, significantly shortening installation time, improving installation efficiency, and reducing labor costs and construction cycle.

[0016] 2. Enhanced connection stability: Through the interference fit between the fitting groove and the stepped plate, the nut can be firmly positioned on the U-shaped steel after installation, which can increase the connection stability of the nut and prevent it from loosening. This ensures the reliability of the connection between the fastened part and the U-shaped steel. It can also be used as a support bracket for connecting with the U-shaped steel to directly fix other parts.

[0017] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] This utility model provides a square nut for use in connecting with U-shaped steel.

[0024] In this embodiment, refer to Figure 1-2 The square nut used for connecting with U-shaped steel includes a nut body 1. The nut body 1 has a threaded hole 2 that runs vertically through the middle. The nut body has symmetrically arranged fitting grooves 3 on both sides. The fitting grooves 3 have elastic grooves 4 on the upper and lower sides. The fitting grooves 3 are interference-fitted with the stepped plate 6 on the opening 5 of the U-shaped steel.

[0025] In the above technical solution, symmetrical fitting grooves are provided on both sides of the nut body. Utilizing the interference fit between the fitting grooves and the upper stepped plate of the U-shaped steel opening, the nut and U-shaped steel are tightly connected. Simultaneously, elastic grooves are provided on the upper and lower sides of the fitting grooves. During the interference fit, the elastic grooves allow for a certain degree of elastic deformation in the fitting groove area, better adapting to differences in the stepped plate dimensions and enhancing connection stability. This effectively prevents the nut from rotating synchronously with the bolt during installation and tightening, significantly improving installation efficiency. It also enhances the firmness of the connection between the nut and the U-shaped steel, reducing safety hazards caused by loosening and extending the service life of the connection structure.

[0026] Specifically, the nut body is provided with a weight reduction groove 7, which is connected to the elasticity enhancement groove.

[0027] In this embodiment, a weight-reducing groove is provided inside the nut body and is connected to an elasticity-enhancing groove. The weight-reducing groove reduces the overall weight of the nut, while the connecting structure expands the elastic range of the elasticity-enhancing groove. This optimizes performance while ensuring structural strength and further improves the reliability of the connection between the nut and the U-shaped steel.

[0028] Specifically, a reinforcing column 8 is provided inside the weight reduction groove, and the reinforcing column 8 has a cross-shaped structure.

[0029] In this embodiment, a cross-shaped reinforcing column is provided within the weight-reducing groove. The cross-shaped structure can provide support and reinforcement to the nut body in all directions, compensating for the strength loss caused by the opening of the weight-reducing groove.

[0030] Specifically, the reinforcing column 8 is fixed to the nut body by bolts 11.

[0031] In this embodiment, the reinforcing column and the nut body are fixed by bolts. This detachable connection method facilitates the installation, replacement or adjustment of the reinforcing column during production or later maintenance.

[0032] Specifically, the opening of the fitting groove is provided with chamfers 12 on both sides.

[0033] In this embodiment, chamfers are provided on both sides of the opening of the fitting groove. The chamfers can guide the stepped plate on the U-shaped steel opening to smoothly enter the fitting groove, reducing the installation difficulty.

[0034] Specifically, thickening rings 13 are provided on the upper and lower end faces of the threaded hole, and the thickening rings 13 are concentrically arranged with the threaded hole.

[0035] In this embodiment, thickening rings coaxial with the threaded hole are provided on the upper and lower end faces of the threaded hole. The thickening rings increase the thickness of the threaded hole end, improving the strength and wear resistance of this part of the threaded hole.

[0036] Specifically, the thickness of the thickening ring is 0.1-0.5 mm.

[0037] In this embodiment, the thickness of the thickening ring is limited to 0.1-0.5 mm. This thickness range ensures that the thickening ring can enhance strength and wear resistance without increasing cost and weight excessively due to excessive thickness.

[0038] Specifically, the thickened ring outer circumferential array has several wedge-shaped plates 14.

[0039] In this embodiment, several wedge-shaped plates are arranged circumferentially around the outer ring of the thickened ring. When the bolts are tightened, the wedge-shaped plates can further compress the surrounding material, increasing friction and also playing a role in preventing loosening to some extent.

[0040] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
