DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0026] The utility model provides technical schemes: as Figures 1 to 6 Indicated, in the embodiment, the rotating seat for bicycle seat tube clamp, including first rotating block 1 and second rotating block 2, the top end of first rotating block 1 is clamped with second rotating block 2, the side center of first rotating block 1 away from second rotating block 2 is fixedly connected with limiting block 103 at both ends, the end of limiting block 103 away from first rotating block 1 is connected with the clamping arm on the tube clamp, the shape of the two limiting blocks 103 on the side of first rotating block 1 is same with the shape of the connecting place of the clamping arm on the tube clamp, the hollow outer hexagonal joint 3 for connecting with the handle of the tube clamp is sleeved in the inner center of second rotating block 2.

[0027] The first rotating block 1 and second rotating block 2 of assembly are completed, one end of hollow outer hexagonal joint 3 is clamped into the inner surface of handle on the tube clamp, one end of limiting block 103 is clamped into the outer surface of clamping arm on the tube clamp, first rotating block 1 and second rotating block 2 of assembly are fixed between clamping arm and handle.

[0028] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 And Figure 5As shown, the first rotating block 1 has a slot 101 inside, and recesses 102 are fixedly installed on both sides inside the slot 101. The second rotating block 2 has a locking block 201 fixedly connected to both sides of the center of the side near the first rotating block 1 and the other two sides of the center of the side near the two locking blocks 201. The bottom end of the locking block 201 is inserted into the inside of the slot 101, and the protruding surface of the wedge-shaped positioning block 202 fits against the inside of the recess 102 near the groove surface of the recess 102.

[0029] Insert the locking block 201 into the locking slot 101. At this time, the abutment ring 104 engages with the limiting block 103, allowing the first rotating block 1 and the second rotating block 2 to be assembled. After assembly, the installer manually rotates the second rotating block 2 in the forward direction and the first rotating block 1 in the reverse direction. The force generated by the rotation will lock the wedge-shaped positioning block 202 into the recess 102. The protruding surface of the wedge-shaped positioning block 202 is tightly fitted with the groove surface of the recess 102, thereby achieving the positioning of the first rotating block 1 and the second rotating block 2.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 as well as Figure 4 As shown, an abutment ring 104 is fixedly sleeved at the center of the first rotating block 1, and a receiving cavity 203 is opened at the center of the second rotating block 2. The end of the receiving cavity 203 near the outside of the abutment ring 104 is engaged inside the receiving cavity 203.

[0031] The outer surface of the abutment ring 104 is in contact with the inner wall of the receiving cavity 203. When the first rotating block 1 and the second rotating block 2 rotate relative to each other, the abutment ring 104 can rotate within the receiving cavity 203.

[0032] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first rotating block 1, the second rotating block 2 and the hollow hexagonal connector 3 are all provided with insertion holes for fixing the shaft on the pipe clamp. The contact surfaces of the first rotating block 1 and the second rotating block 2 are provided with anti-slip texture 4, which is a cross-grid structure.

[0033] The anti-slip texture 4 on the contact surface of the first rotating block 1 and the second rotating block 2 increases the friction of the contact surface, making it less likely for the first rotating block 1 and the second rotating block 2 to slip when rotating relative to each other, thus ensuring the stability and reliability of the rotating seat.

[0034] In order to facilitate the understanding of the cooperation effect of the rotating seat, the telescopic rod, the pipe clamp, the clamping arm and the handle of the bicycle seat tube clamp, see Figure 7 , wherein Figure 7 is the drawing in the bicycle seat tube quick release device, bicycle seat tube assembly and bicycle invention patent.

[0035] The utility model provides a rotating seat for bicycle seat tube clamp, specific working principle is as follows: in the use, the clamping block 201 is inserted into the card slot 101, at this moment, the abutment ring 104 is clamped with the limiting block 103, so that the first rotating block 1 and the second rotating block 2 can be assembled, after assembling, the installation personnel manually rotates the second rotating block 2 in the positive direction, and the first rotating block 1 is rotated in the reverse direction, the force generated by rotation is clamped into the recessed block 102 with the wedge-shaped positioning block 202, the convex surface of the wedge-shaped positioning block 202 is closely combined with the recess surface of the recessed block 102, so that the positioning of the first rotating block 1 and the second rotating block 2 is realized, the first rotating block 1 and the second rotating block 2 after assembling, one end of the hollow outer hexagonal joint 3 is clamped into the inner surface of the handle on the pipe clamp, one end of the limiting block 103 is clamped into the outer surface of the clamping arm on the pipe clamp, so as to fix the first rotating block 1 and the second rotating block 2 between the clamping arm and the handle after assembling;

[0036] The height of people is different, when riding a bicycle, the height of the saddle needs to be adjusted according to the height of the individual. This can be realized by rotating the handle to tighten or loosen the pipe clamp on the telescopic rod. During the rotation of the handle, the two sets of wedge-shaped positioning blocks 202 move along the arc surface of the two sets of recessed blocks 102 under the action of the handle torsion force. It should be noted that, since the two sets of clamping blocks 201 are fixed in the card slot 101, the movement distance of the wedge-shaped positioning block 202 on the arc surface of the recessed block 102 is limited, thereby preventing the first rotating block 1 and the second rotating block 2 from being separated excessively. The force generated by this separation will cause the distance between the clamping arms on the pipe clamp to be shortened, which limits the clamping force of the pipe clamp on the telescopic rod. The limited clamping force ensures that the clamping force is not too large when the lock is released, and the inner surface of the pipe clamp is still tightly attached to the surface of the telescopic rod. Therefore, when adjusting the telescopic rod, even if the pipe clamp is loosened, the telescopic rod will not fall out of the bicycle seat tube due to the excessive clamping range.

[0037] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
