Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to the technical field of T-bolts. Background Art

[0002] Bolt: A mechanical part, a cylindrical threaded fastener that is matched with a nut. A type of fastener consisting of a head and a cylindrical body with external threads on the screw rod, which needs to be matched with a nut to fasten and connect two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. T-bolts are a type of bolt, and are specially used for channel steel. They usually include a head and a rod, and the rod is provided with threads.

[0003] For example, the Chinese utility model patent with publication number CN203161766U proposes a T-bolt specially used for channel steel, including a head and a rod, the rod being provided with threads, the outer wall of the rod being provided with a slot, the slot being provided on the rod in the axial direction of the rod, and the cross section of the slot being provided in a "V" shape. Due to the effect of the slot, the technical solution of this utility model reduces the gap between the bolt and the channel steel caused by thermal expansion and contraction, thereby reducing looseness and making the connection more stable. However, the problem with this structure for T-bolts is that the T-bolts need to be placed in the corresponding holes of the channel steel in advance when used, and then the nuts are fixed. Before the nuts are fixed, the T-bolts are not subjected to force in the holes of the channel steel, and are very easy to loosen and fall off, thus causing loss, and subsequent tightening is inconvenient. Summary of the invention

[0005] To achieve the above-mentioned purpose, the utility model proposes an anti-slip T-bolt, including a screw and a T-head transversely arranged at one end of the screw, the surface of the screw is provided with an external thread, and one end of the screw close to the T-head is provided with a plurality of clamping mechanisms, the clamping mechanisms include a groove body arranged on the outer wall of the screw and an elastic card arranged in the groove body, one end of the elastic card extends outside the groove body and protrudes from the outer wall of the screw, and the part of the elastic card extending out of the groove body is in an arc shape that gradually inclines toward the T-head direction from close to the center end of the screw to away from the center end of the screw.

[0006] Preferably, the surface of the screw is provided with a concave glue groove, a capsule body is provided in the glue groove, the capsule body is filled with screw glue, and one side of the capsule body protrudes from the surface of the screw.

[0007] Preferably, each of the clamping mechanisms is arranged on the surface of the screw in a ring array around the center of the screw.

[0008] Preferably, the elastic card comprises a clamping fixing head and a spring sheet extending from the clamping fixing head in a direction away from the center of the screw rod, the spring sheet is arc-shaped, and the clamping fixing head is clamped and connected to the slot body.

[0009] Preferably, the clamping fixing head is integrally formed with the spring sheet and is formed by integrally bending a metal strip.

[0010] Preferably, an outer groove extending in the direction of the T-shaped head is provided at the opening of the groove body, the outer groove is adapted to the elastic card, and the end of the elastic card can be accommodated in the outer groove after being bent.

[0011] Preferably, a polished rod section is provided at the connecting end between the screw rod and the T-head, and the clamping mechanism is provided at the polished rod section.

[0012] The utility model discloses a T-bolt with anti-slip effect: the utility model provides a clamping mechanism at the bottom of the screw rod, and the clamping mechanism can cooperate with the screw hole on the channel steel to fix the bolt in the screw hole, so as to prevent the bolt from loosening and falling off before being tightened, thereby affecting the tightening efficiency of the bolt. The bolt is more convenient to use and easier to operate. A capsule body is provided on the screw rod, and screw glue is provided in the capsule body.
