Description
Technical Field
[0001] The present application relates to the field of bicycle saddles, and in particular to a simple clip. Background Art
[0002] In response to the country's call for low-carbon travel, more and more people are choosing to travel by bicycle, which is a zero-emission means of transportation that helps reduce air pollution and traffic congestion.
[0003] The saddle is an indispensable and important part installed on the seat tube of a bicycle to provide sitting support. The existing saddle and the seat tube are usually connected by a clamp. The existing clamp usually includes a seat tube clamp, a left clamp, a right clamp, and a clamping piece used to clamp the suspension on the saddle in cooperation with the left clamp and the right clamp. When in use, the seat tube is inserted into the seat tube clamp, and then the two suspensions on the saddle are respectively arranged between the left clamp and the clamping piece and between the right clamp and the clamping piece, and then a screw bolt is passed through the seat tube clamp, the left clamp, the right clamp and the two clamping pieces, and then nuts are used to seal both sides of the screw bolt. The suspension is connected to the seat tube, and then the saddle is connected to the seat tube, and the existing left clamp and the right clamp are rotatably connected to the clamping pieces corresponding to them.
[0004] The above-mentioned existing technical solutions have the following defects: the existing clamps use a large number of splicing parts, and the production cost is high when the materials of the same material and the same specification are used for manufacturing; and the existing left clamp and the right clamp are rotatably connected with the clamping pieces corresponding thereto, so there is a problem of the angle between the saddle and the seat tube being deflected during riding, which affects the riding comfort. Utility Model Content
[0005] In order to reduce the production cost of the clamp and to improve the riding comfort by adjusting the angle of the saddle and the seat tube when the clamp is used to connect the saddle and the seat tube, the angle of the saddle is determined during riding.
[0006] The above technical objectives of this application are achieved through the following technical solutions:
[0007] A simple clamp comprises a seat tube clamp, wherein a first clamp and a second clamp are respectively arranged on both sides of the seat tube clamp; there are gaps between the first clamp and the second clamp and the seat tube clamp; a connecting component for pushing the first clamp and the second clamp toward the middle and tightening the clamping angle of the seat tube is arranged between the first clamp, the second clamp and the seat tube clamp; locking grooves are arranged on both sides of the seat tube clamp away from each other, and locking pins are fixedly connected to the first clamp and the second clamp, and the locking pin is plugged and matched with the locking grooves; a plurality of anti-rotation grooves are arranged on the locking grooves, and a plurality of anti-rotation rods are fixedly connected to the locking pins, and when the locking grooves are plugged and matched with the locking pins, the anti-rotation pins are plugged and matched with the anti-rotation rods.
[0008] By adopting the above scheme, the seat tube is inserted into the seat tube clamp, and the two suspensions are located on both sides of the seat tube clamp. Then the first clamp and the second clamp are buckled on the side where the two suspensions are away from each other. At this time, the first clamp, the second clamp and the seat tube clamp are connected and tightened by the connecting assembly, that is, the seat tube clamp is tightened to clamp the seat tube, and the first clamp and the second clamp are tightened in the direction of approaching each other, so that the two suspensions are fixed between the seat tube clamp and the first clamp and the second clamp; so that the seat tube and the suspension are connected together, and the saddle and the seat tube are further connected together, which is different from the existing clamp code In comparison, the clamp uses fewer splicing structures, optimizes the two clamping plates, and achieves the effect of reducing the production cost of the clamp; the locking pin and the locking groove are plugged together to limit the positional relationship between the first clamp and the seat tube clamp and the positional relationship between the second clamp and the seat tube clamp; the anti-rotation pin and the anti-rotation rod are plugged together, so that after the locking pin and the locking groove are connected, the locking pin and the locking groove will not rotate relative to each other, thereby preventing the angle between the seat tube and the saddle from rotating, and further preventing the angle of the saddle from being determined during riding without deflection, thereby achieving the effect of improving riding comfort.
[0009] Furthermore, the first clamp and the second clamp are both provided with an annular groove on one side close to the seat tube clamp, and the annular groove is used for engaging with the suspension.
[0010] By adopting the above solution, the annular groove is consistent with the curvature of the suspension, which can avoid suspension displacement.
[0011] By adopting the above solution, the anti-rotation pin and the anti-rotation rod are plugged and matched, so that the connection between the locking pin and the locking groove is more stable.
[0012] Furthermore, the connection assembly includes a connection piece and a sealing ring, through holes are provided on both sides of the first clamp, the second clamp and the seat tube clamp, and the connection piece passes through each through hole in turn and is threadedly connected to the sealing ring.
[0013] Furthermore, one end of the connecting piece is fixedly connected to the limiting piece, and the other end of the connecting piece is provided with a thread, and the thread is used for threaded connection with the sealing ring.
[0014] By adopting the above solution, the sealing ring and the limiting member are located on the side where the first clamp and the second clamp are away from each other, so that the connection between the first clamp, the second clamp and the seat tube clamp is more stable.
[0015] Furthermore, the area of the connecting member between the thread and the limiting member is rectangular.
[0016] Furthermore, the connecting piece is a hollow structure as a whole, which is used to reduce the weight of the connecting piece.
[0017] Furthermore, the diameter of the connecting piece gradually increases from the threaded area to the rectangular area.
[0018] By adopting the above scheme, the connecting piece is gradually transitioned from the threaded area to the rectangular area, avoiding the misalignment between the threaded area and the rectangular area, resulting in the position between the second clip and the seat tube clamp being fixed; thereby avoiding the situation where there is no movable space between the first clip, the second clip and the seat tube clamp when the sealing ring is rotated because the position between the second clip and the seat tube clamp is fixed.
[0019] In summary, this application has the following technical effects:
[0020] 1. By setting the clamp, the seat tube is plugged into the seat tube clamp, and the two suspensions are located on both sides of the seat tube clamp. Then the first clamp and the second clamp are buckled on the side where the two suspensions are away from each other. At this time, the first clamp, the second clamp and the seat tube clamp are connected by the connecting assembly, that is, the saddle is connected to the seat tube. Compared with the existing clamp, the clamp uses fewer structures, thereby achieving the effect of reducing the production cost of the clamp;
[0021] 2. By setting an annular groove, the annular groove is consistent with the curvature of the suspension, which can avoid suspension displacement;
[0022] 3. By providing an anti-rotation pin and an anti-rotation rod, the anti-rotation pin and the anti-rotation rod are plugged together, so that the connection between the locking pin and the locking groove is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0028] The present application is further described in detail below in conjunction with the accompanying drawings.
[0029] Reference Figure 1 The present embodiment provides a simple clamp, which is arranged between the saddle 1 body and the seat tube 3, and is used to connect the suspension 2 on the saddle 1 and the seat tube 3 together.
[0030] Reference Figure 1 The clamp comprises a seat tube clamp 4, a first clamp piece 5 and a second clamp piece 6. The seat tube clamp 4 is U-shaped as a whole. The seat tube 3 is inserted into the seat tube clamp 4 and is arranged close to the bottom wall of the U-shape. The first clamp piece 5 and the second clamp piece 6 are respectively arranged on two sides of the seat tube clamp 4 away from each other. The first clamp piece 5 and the second clamp piece 6 are both provided with annular grooves 8, and the notches of the two annular grooves 8 correspond to each other. The two suspensions 2 on the saddle 1 are respectively engaged with the two annular grooves 8. A connecting component 7 is also arranged between the seat tube clamp 4, the first clamp piece 5 and the second clamp piece 6. The connecting component 7 passes through the first clamp piece 5, the seat tube clamp 4 and the second clamp piece 6 in sequence, and the connecting component 7 connects the three together.
[0031] Reference Figure 1 The connecting assembly 7 includes a connecting piece 71 and a sealing ring 72. One end of the connecting piece 71 is provided with a thread, and the other end of the connecting piece 71 is fixedly connected to the limiting piece 40. In this embodiment, the limiting piece 40 plays a role of sealing; through holes are provided on both sides of the first clamp 5, the second clamp 6 and the seat tube clamp 4, and one end of the connecting piece 71 with a thread passes through the through holes of the first clamp 5, the seat tube clamp 4 and the second clamp 6 in turn and is threadedly connected to the sealing ring 72. At this time, the limiting piece will abut against the side of the first clamp 5 away from the seat tube clamp 4; in this embodiment, the limiting connecting piece 71 is inserted into the through hole on the first clamp 5; the connecting piece 71 is a hollow structure, which can reduce the weight of the connecting piece 71 and save production costs.
[0032] Reference Figure 2-Figure 3, locking grooves 9 are provided on both sides of the seat tube clamp 4 that are away from each other. In the present embodiment, two locking grooves 9 are provided on each side of the seat tube clamp 4, and a locking pin 10 is fixedly connected to each locking groove 9 corresponding to a side of the first clamp 5 and the second clamp 6 close to the seat tube clamp 4, and each locking pin 10 is plugged into and matched with the locking groove 9; so that the first clamp 5 and the second clamp 6 are plugged into and matched with the seat tube clamp 4; each locking groove 9 side wall is provided with two anti-rotation grooves 20, and an anti-rotation rod 30 is fixedly connected to each locking pin 10 corresponding to each anti-rotation groove 20, and the anti-rotation rod 30 is plugged into and matched with the anti-rotation groove 20, so that the insertion of the locking pin 10 and the locking groove 9 can be more stably.
[0033] Reference Figure 2 and Figure 4 The portion of the connecting piece 71 between the limit piece 40 and the threaded area is rectangular, and the diameter of the connecting piece 71 gradually increases from the threaded area to the rectangular area. This arrangement allows the connecting piece 71 to gradually transition from the threaded area to the rectangular area, thereby avoiding misalignment between the threaded area and the rectangular area, thereby avoiding the position between the second clip 6 and the seat tube clamp 4 being fixed due to the misalignment, and avoiding the situation where, when the sealing ring 72 is rotated, there is no movable space between the first clip 5 and the second clip 6 and the seat tube clamp 4, thereby preventing the first clip 5 and the second clip 6 from being tightened with the seat tube clamp 4.
[0034] The implementation principle of a simple clamp code in an embodiment of the present application is: insert the seat tube 3 into the seat tube clamp 4, then respectively clamp the two suspensions 2 in the two annular grooves 8, then each locking pin 10 is plugged into and matched with the corresponding locking groove 9, and each anti-rotation rod 30 is plugged into and matched with the corresponding anti-rotation groove 20; then the threaded end of the connecting piece 71 is sequentially passed through the through holes of the first clamp 5, the seat tube clamp 4 and the second clamp 6 and threadedly connected with the sealing ring 72, thereby completing the installation of the saddle 1 and the seat tube 3.
