A T-shaped bolt capable of quick positioning

Abstract

This invention provides a T-bolt capable of rapid positioning, comprising a screw rod, a screw head, a hole, a top pin, a spring, an anti-slip pad, and an aluminum profile. The screw rod and screw head are integrally formed, with a hole at the center of the screw head. The top pin is elastically slidably mounted within the hole via a spring, and an anti-slip pad is positioned on the surface of the screw head. The screw head can extend into the groove of the aluminum profile. This invention uses a spring to drive the top pin to elastically contact the bottom of the aluminum profile groove, causing the screw head to automatically lift after rotating into position. The anti-slip pad tightly adheres to the inner wall of the groove, achieving automatic vertical / horizontal positioning of the bolt and improving installation efficiency. Simultaneously, the micro-convex texture of the anti-slip pad mechanically engages with the inner wall of the groove, enhancing anti-loosening performance and resisting vibration.

Description

Technical Field

[0001] This utility model belongs to the field of T-bolt technology, and in particular relates to a T-bolt that can be quickly positioned. Background Technology

[0002] T-bolts, commonly used fasteners for connecting aluminum profile frames, are widely used in industrial automation equipment, logistics conveying systems, and exhibition display structures. Traditional T-bolts require the bolt head to be inserted into the aluminum profile slot and rotated 90° during installation. Due to the assembly gap (typically 0.2-0.5mm) between the slot and the bolt head, the bolt is prone to tilting or falling over. This necessitates additional support and positioning during subsequent nut tightening, resulting in low installation efficiency and high labor intensity. Furthermore, the smooth surface of conventional T-bolts makes them susceptible to loosening under vibration, affecting connection reliability.

[0003] Therefore, it is essential to invent a T-bolt that can be quickly positioned. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a T-bolt that can be quickly positioned, including a screw, a screw head, a hole, a top pin, a spring, an anti-slip pad, and an aluminum profile. The screw and the screw head are integrally set together. The screw head has a hole in its center. The top pin is elastically slidably installed in the hole by the spring. The anti-slip pad is provided on the surface of the screw head. The screw head can extend into the groove of the aluminum profile.

[0005] Preferably, the screw and the screw head are integrally formed into a T-bolt structure, and the top pin can slide axially within the hole opened in the screw head.

[0006] Preferably, one end of the top pin extends outward, and its half-width structure protrudes outward from the hole of the screw head. The outwardly protruding end face of the top pin can contact the bottom surface of the groove of the aluminum profile, and the outwardly protruding end face of the top pin is smooth.

[0007] Preferably, the two anti-slip pads are located on both sides of the connection between the screw head and the screw rod. The surface of the anti-slip pad is provided with anti-slip texture, and the surface of the anti-slip pad with anti-slip texture can contact the inner wall surface of the opening of the aluminum profile groove.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] This invention utilizes a spring-driven top pin to make elastic contact with the bottom of the aluminum profile groove, causing the screw head to be immediately lifted after being rotated into position. The anti-slip pad fits tightly against the inner wall of the groove, achieving automatic vertical / horizontal positioning of the bolt without the need for manual support, thus significantly improving installation efficiency.

[0010] The micro-convex anti-slip texture (preferably toothed or grid-like structure) on the surface of the anti-slip mat of this utility model forms a mechanical engagement with the inner wall of the aluminum profile groove, effectively resisting the risk of loosening under vibration.

[0018] As attached Figure 1 To be continued Figure 3 As shown:

[0019] This utility model provides a T-bolt capable of rapid positioning, comprising a screw 1, a screw head 2, a hole 3, a top pin 4, a spring 5, an anti-slip pad 6, and an aluminum profile 7. The screw 1 and the screw head 2 are integrally formed together. The screw head 2 has a hole 3 in its center. The top pin 4 is elastically slidably installed in the hole 3 by the spring 5. The anti-slip pad 6 is provided on the surface of the screw head 2. The screw head 2 can extend into the groove of the aluminum profile 7.

[0020] Furthermore, the screw 1 and screw head 2 are manufactured using a one-piece forging process with 304 stainless steel to form the main structure of the T-bolt. The length and width of the screw head 2 are designed according to the corresponding aluminum profile slot size. For example, when adapting to 20 series profiles, the screw head size is 18mm × 12mm. The hole 3 is opened at the central axis of the screw head 2, and the hole diameter is 0.2-0.3mm larger than the outer diameter of the top pin 4, forming a clearance fit to ensure that the top pin 4 can slide smoothly axially within the hole 3.

[0021] Furthermore, the top pin 4 is made of alloy steel, with one end extending outward to form a boss structure with a reduced diameter, and the half-width structure protruding outward from the hole 3. The outwardly protruding end face of the top pin 4 is ground and polished to form a surface contact sealing structure when it contacts the bottom of the groove of the aluminum profile 7. The spring 5 is made of spring steel, with an outer diameter 0.5mm smaller than the inner diameter of the hole 3, and is installed in the blind hole of the top pin 4 to ensure that the top pin 4 maintains a half-width outwardly protruding state in a free state.

[0022] Furthermore, the anti-slip pad 6 is supported by EPDM rubber and is embedded in the rectangular grooves reserved on both sides of the screw head 2 through a vulcanization process. The surface of the anti-slip pad 6 is provided with a diamond-shaped grid anti-slip texture (texture depth 0.3-0.5mm, spacing 2mm) or a toothed raised texture. Its installation position is located symmetrically on both sides of the connection between the screw head 2 and the screw rod 1. When the screw head 2 is rotated into place, the anti-slip pad 6 is in close contact with the inner wall surface of the groove opening of the aluminum profile 7.

[0023] The working principle is as follows: First, insert the screw head 2 into the groove along the groove direction of the aluminum profile 7. At this time, the outer convex end face of the top pin 4 contacts the bottom surface of the groove and is squeezed. The spring 5 begins to compress, and the top pin 4 slides into the hole 3.

[0024] Next, rotating screw 1 drives screw head 2 to rotate 90°, making screw head 2 perpendicular to the groove. At this time, the elastic potential energy of spring 5 is released, pushing top pin 4 to slide outward until anti-slip pad 6 is in close contact with the inner wall surface of the groove opening.

[0025] Finally, the diamond-shaped grid pattern on the surface of the anti-slip pad 6 generates friction with the inner wall of the groove, while the outer convex end face of the top pin 4 maintains surface contact with the bottom of the groove, together keeping the T-bolt in a vertical or horizontal state, achieving rapid positioning.

[0026] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
