Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing and processing technology, specifically a T-shaped nut. Background Technology

[0002] T-nuts, as a type of high-efficiency fastener with a T-shaped cross-section, are characterized by a combination of a wide head and a slender threaded shank. The head is embedded in the T-slot of the profile or a pre-drilled hole in the plate through barbs or hooks, and is further enhanced by surface treatments such as galvanizing and nickel plating to improve corrosion resistance. The thread specifications strictly follow international standards to adapt to different bolts. The head is made to fit tightly against the inner wall of the substrate by tapping or pressing, and then a bolt or screw is screwed into the threaded shank to achieve a firm connection. They are widely used in industrial automation, furniture manufacturing, construction, and transportation.

[0003] When using T-nuts, they usually need to be pre-fixed to the screw before being placed into the fixing groove and then tightened to fix the nut. However, during the tightening process, the nut itself is prone to deflection, resulting in insufficient tightening force, which affects the fixing effect, or even causes the nut to slip out of the fixing groove and fall off, affecting its use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a T-type nut to solve the technical problem that the nut is prone to deflection during the tightening process, resulting in insufficient tightening force, affecting the fixing effect, or even the nut slipping out of the fixing groove and falling off.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a T-shaped nut, comprising a nut seat and a fixing mechanism, wherein the fixing mechanism includes a sliding groove, a sliding rod is engaged and slidably disposed within the sliding groove, the sliding rod has an insertion hole, a support block is fixedly connected to one end of the sliding rod, and a groove is formed on the outer surface of the support block;

[0006] The top of the chute is provided with a secondary threaded hole, and a fixing bolt is connected to the secondary threaded hole by a thread.

[0007] By adopting the above technical solution, the engagement and sliding of the slide groove and the slide rod allow the position of the fixing mechanism to be flexibly adjusted according to actual needs, which can make the fixing mechanism fit better with the installation surface and improve the installation quality.

[0008] Furthermore, the slide bar is provided in two sets, with two slide bars in each set.

[0009] By adopting the above technical solution, two sets of sliding rods support the support block from different directions. Compared with a single set of sliding rods, the force borne by the support block can be distributed more evenly, thus improving the support stability of the entire fixing mechanism.

[0010] Furthermore, the socket is provided in a plurality of manners, and the plurality of sockets are arranged in a linear array at equal intervals.

[0011] By adopting the above technical solution and setting several insertion holes, the T-nut can be adapted to a variety of connection components of different specifications or structures, thereby improving the versatility and applicability of the nut and meeting diverse connection needs.

[0012] Furthermore, the grooves are provided in two sets, and each set of grooves is arranged in a linear array with several grooves evenly spaced.

[0013] By adopting the above technical solution and setting two sets of grooves, more contact points can be provided between the T-nut and the fixing groove, forming a multi-point stable connection, making the connection more stable, reducing the risk of nut loosening or damage due to uneven force, and ensuring the reliability of the connection.

[0014] Furthermore, a nut head is fixedly connected to the top of the nut seat, and a main thread hole is formed on the top of the nut head.

[0015] By adopting the above technical solution, the nut seat and the nut head are fixedly connected, so that the entire T-nut forms a stable integral structure. During installation and use, this fixed connection method can effectively resist the action of external forces.

[0016] Furthermore, the nut head has abutment surfaces on both sides, and the outer surface of the abutment surfaces has several protrusions.

[0017] By adopting the above technical solution, abutment surfaces are provided on both sides of the nut head, providing a stable contact base for the nut during installation, ensuring that the nut will not tilt or shake during installation, and providing reliable support for subsequent tightening operations.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model, by setting a fixing mechanism, in which the sliding groove and the sliding rod cooperate, and the sliding rod is provided with multiple insertion holes, allows for flexible adjustment of the position and fixing point of the sliding rod, thereby adapting to fixing grooves of different specifications and shapes. This ensures that the support block and the opening of the fixing groove are tightly fitted, increasing the contact area and friction between the nut and the fixing groove, effectively preventing the nut from deflecting or slipping out due to uneven force during tightening, and improving the stability and reliability of the fixing. When tightening external bolts, the presence of the support block provides additional support force for the nut, effectively resisting the torque generated during bolt tightening, preventing the nut seat from rotating, ensuring the vertical relationship between the nut and the fixing groove, and guaranteeing the effective transmission of tightening force and the reliability of the fixing effect.

[0020] 2. By setting protrusions, the present invention significantly increases the contact area and friction between the nut head and the fixing groove by setting several protrusions on the abutment surfaces on both sides of the nut head. This helps to maintain the stability of the nut during tightening, prevents it from loosening due to vibration or external force, and improves the reliability of fixing. The protrusions disperse the contact stress between the nut head and the surrounding structure, avoiding damage or deformation caused by local stress concentration. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] A type of T-nut, such as Figures 1-4 As shown, it includes a nut seat 1 and a fixing mechanism 6. The fixing mechanism 6 includes a slide groove 607, in which a slide rod 601 is engaged and slidably moved. The slide rod 601 has an insertion hole 602. One end of the slide rod 601 is fixedly connected to a support block 603. The outer surface of the support block 603 has a groove 604.

[0028] The top of the slide groove 607 is provided with a secondary threaded hole 605, and a fixing bolt 606 is connected to the secondary threaded hole 605 by thread. The engagement and sliding of the slide groove 607 and the slide rod 601 allows the position of the fixing mechanism 6 to be flexibly adjusted according to actual needs, so that the fixing mechanism 6 can better fit with the mounting surface and improve the installation quality. The presence of the support block 603 increases the contact area between the fixing mechanism 6 and the connected parts, which can evenly transmit pressure to the connected parts and avoid damage to the connection parts due to excessive pressure.

[0029] See Figure 2 , Figure 3 There are two sets of slide rods 601, with two slide rods in each set. The two sets of slide rods 601 support the support block 603 from different directions. Compared with a single set of slide rods 601, the force borne by the support block 603 can be distributed more evenly, which improves the support stability of the entire fixing mechanism 6. The operator can adjust the position of the two slide rods 601 respectively to adapt to different installation requirements and ensure that the entire fixing mechanism 6 can be installed smoothly and work normally.

[0030] See Figure 2 , Figure 3 The T-nut has several sockets 602 arranged in a linear array at equal intervals. The arrangement of several sockets 602 allows the T-nut to be adapted to various connecting parts of different specifications or structures, improving the versatility and applicability of the nut and meeting diverse connection needs. The linear array of equally spaced sockets 602 helps to improve installation accuracy, ensure the installation accuracy of connecting parts, and guarantee the performance and quality of the equipment.

[0031] See Figure 2 , Figure 3 The grooves 604 are provided in two sets, with several grooves 604 arranged in a linear array at equal intervals. The two sets of grooves 604 provide more contact points between the T-nut and the fixing groove, forming a multi-point stable connection, making the connection more secure, reducing the risk of nut loosening or damage due to uneven force, and ensuring the reliability of the connection. The linear array of grooves 604 at equal intervals can make the contact force between the protrusions on the connecting parts and the grooves 604 evenly distributed, extending the service life of the nut and connecting parts, and improving the stability and reliability of the connection.

[0032] See Figure 1 , Figure 4 The top of the nut seat 1 is fixedly connected to the nut head 5, and the top of the nut head 5 is provided with a main thread hole 4. The nut seat 1 and the nut head 5 are fixedly connected, so that the entire T-nut forms a stable integral structure. During installation and use, this fixed connection method can effectively resist the action of external forces. The external bolt can be threaded to the nut head 5 through the main thread hole 4, thereby firmly fixing the connected parts together.

[0033] See Figure 1 , Figure 4The nut head 5 has abutment surfaces 2 on both sides, and a number of protrusions 3 on the outer surface of the abutment surfaces 2. The abutment surfaces 2 on both sides of the nut head 5 provide a stable contact base for the nut during installation, ensuring that the nut will not tilt or shake during installation, and providing reliable support for subsequent tightening operations. The protrusions 3 can provide additional friction to resist the influence of vibration on the nut head 5, ensuring that the nut seat 1 always maintains a stable fixed state.

[0034] The implementation principle of this utility model is as follows: First, the external bolt is pre-screwed into the main thread hole 4. Then, the nut is inserted into the fixing groove. Then, the nut is rotated 90 degrees so that the nut is placed horizontally and the nut head 5 is placed at the opening of the fixing groove. Then, the support blocks 603 are spread out to both sides so that the support blocks 603 are fixed to the opening of the fixing groove. Then, the fixing bolt 606 is tightened so that the bottom end of the fixing bolt 606 enters the insertion hole 602 to fix the slide rod 601. Then, the external bolt is tightened. At the same time, the support blocks 603 can effectively prevent the nut seat 1 from rotating, so that the nut seat 1 is perpendicular to the opening of the fixing groove.
