Detailed Description

The scheme of the application is further described by the following combined drawings:

referring to fig. 1 to 6, a seat adjusting bolt 100 includes a yoke 2 and a bolt body 1 installed inside the yoke 2, the yoke 2 having a notch, one end of the bolt body 1 protruding from the notch and the other end being threadedly engaged with the inside of the yoke 2; the bolt main body 1 comprises a main body part 11 and a connecting part 12 positioned at the tail end of the main body part 11; the main body part 11 has a square cross section; the outer wall of connecting portion 12 is equipped with the screw thread, the inboard of clamp 2 is equipped with screw hole 20, connecting portion 12 with the screw hole 20 spiro union. During installation, the connecting portion 12 of the plug body 1 is screwed into the threaded hole 20 of the yoke 2.

According to the seat adjusting bolt 100, the bolt body 1 is in threaded connection with the hoop 2 through the connecting portion 12, the assembling operation is simple and fast, and the efficiency is high. In addition, the main part 11 cross-section of bolt main part 1 is square, and with the quad slit cooperation of telescopic link 200, has restricted bolt main part 1 and has rotated for telescopic link 200, and the use can not influence the stability of being connected with clamp 2 because of bolt main part 1 rotation.

The clamp 2 comprises a C-shaped main body 21 and a convex part 22 which protrudes outwards from the middle part of the C-shaped main body 21; the threaded hole 20 is provided inside the middle portion of the yoke 2.

The convex part 22 is used for being held by a user, so that the clamping hoop 2 is convenient to carry out the matched installation or disassembly of the seat bolt and the telescopic rod 200; in addition, the boss 22 increases the thickness of the middle part of the C-shaped main body 21, and facilitates the processing of the threaded hole 20.

The inner side surface of the hoop 2 is covered with an elastic anti-slip layer 23, so that the friction force between the hoop 2 and the telescopic rod 200 is enhanced, and the hoop is not easy to loosen.

Further, elasticity skid resistant course 23 covers to the lateral surface of clamp 2, specifically is the cladding at the elastic plastic cover of the medial surface of clamp 2 and lateral surface, and elastic plastic cover is easy to assemble, and hugs closely with clamp 2 through self elasticity.

The elastic anti-slip layer 23 is formed with a plurality of elastic protrusions 24 corresponding to two ends of the inner side surface of the C-shaped main body 21. Further reinforcing frictional force improves the cooperation stability of clamp 2 and flexible outer tube 4.

The elastic salient points 24 are distributed at intervals along the axial direction of the C-shaped main body 21, are vertical to the pulling-out direction of the hoop 2, and have large friction force.

A seat telescopic rod 200 structure comprises a telescopic rod 200 and the seat adjusting bolt 100, wherein the top of the telescopic rod 200 is connected with a seat cushion, and the bottom of the telescopic rod is connected with a seat leg frame.

The telescopic rod 200 comprises a telescopic inner tube 3 and a telescopic outer tube 4, wherein the telescopic inner tube 3 is nested in the telescopic outer tube 4 and can be adjusted in a telescopic manner along the telescopic outer tube 4 in a vertical movement manner.

The telescopic inner pipe 3 is provided with a plurality of adjusting holes 31 which are distributed at intervals along the axial direction of the telescopic inner pipe 3, the telescopic outer pipe 4 is provided with a positioning hole 41, and the bolt main body 1 is arranged in the positioning hole 41 and the adjusting holes 31 at different positions in a penetrating manner so as to fix the position of the telescopic inner pipe 3; the hoop 2 hoops on the telescopic outer tube 4 and the inner side surface of the hoop 2 is tightly attached to the telescopic outer tube 4.
