Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bicycle production, and particularly relates to a bicycle adjusting mechanism and a bicycle. BACKGROUND

[0002] A bicycle, also known as a cycle or a bike, is usually a small, human-powered, land vehicle with two wheels. The bicycle is a small transportation tool driven by pedaling, and is a green and environmentally-friendly transportation tool with functions of fitness and travel, and is deeply loved by people.

[0003] The existing bicycle is provided with a seat, and the seat is inserted into a frame through a plug rod. When a user uses the bicycle, the height of the seat is adjusted according to the height of the user, and therefore, an adjusting mechanism for adjusting the height of the seat is arranged on the frame. At present, a buckle is arranged on the frame, the buckle is loosened when the height is adjusted, the position of the seat is manually raised or lowered, and then the buckle is locked to fix the position of the seat.

[0004] However, the stability of the above height adjusting mode is insufficient, and the loosening failure is prone to occur, and the use experience is poor, and therefore, the height adjusting mode needs to be improved. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the stability of the height adjustment of the bicycle seat, the present application provides a bicycle adjusting mechanism.

[0006] In the first aspect, the present application provides a bicycle adjusting mechanism adopting the following technical scheme:

[0007] A bicycle adjusting mechanism comprises a seat tube, a support rod and a friction block. The seat tube is provided with an installation groove along the length direction of the seat tube. The support rod is movably arranged in the installation groove. One end of the support rod is located in the installation groove, and the other end of the support rod is used for mounting a seat. The support rod is provided with a limiting groove along the length direction of the support rod. The friction block is movably arranged on the limiting groove. The support rod and the friction block are locked on the seat tube through a fastener. The friction block is integrally connected with a protruding block. The protruding block penetrates through the seat tube. The protruding block is provided with an installation hole. The installation hole is used for abutting the fastener.

[0008] Preferably, the fastener is a fastening bolt.

[0009] Through the above technical scheme, one end of the fastening bolt penetrates through the seat tube and abuts in the installation hole. By screwing the fastening bolt, the friction block is abutted on the support rod by the fastening bolt, and the fixation of the support rod is realized by the action of the pressure, so as to limit the movement of the support rod in the installation groove.

[0010] When the height of the seat needs to be adjusted, the fastening bolt is loosened first, and then an external force is applied to the support rod to control the movement of the support rod in the mounting groove, thereby changing the height of the seat relative to the ground. During the movement of the support rod, the protrusions are limited by the seat tube, preventing the friction block from moving synchronously with the support rod, i.e., the support rod and the friction block will move relatively. When the support rod is adjusted to the desired position, the fastening bolt is tightened again to complete the fixation of the support rod.

[0013] Preferably, a groove is formed in the friction block, and the groove is used for sleeving the rubber ring.

[0014] By adopting the above technical solution, the rubber ring can be sleeved in the groove. Since the rubber ring is made of a high polymer material, it has a large friction coefficient, and can increase the static friction force between the friction block and the support rod.

[0015] Preferably, a sliding block is integrally connected to the side of the friction block away from the protrusions, and the sliding block is slidingly connected in the limiting groove.

[0016] By adopting the above technical solution, the sliding block and the limiting groove cooperate with each other to realize the connection of the friction block and the support rod, and at the same time, the contact area between the friction block and the support rod is increased, and the stability is improved.

[0017] Preferably, the seat tube and the support rod are made of carbon fiber material.

[0018] By adopting the above technical solution, the carbon fiber material has the characteristics of lightness and high strength, and can improve the use experience and life of the bicycle.

[0019] Preferably, the installation assembly is further provided, which is arranged at one end of the support rod located outside the mounting groove, and is used for assisting the installation of the seat on the seat tube; the installation assembly comprises a first mounting plate, a second mounting plate, a first bolt and a second bolt, the first mounting plate is connected to the support rod, the second mounting plate is located above the first mounting plate, and a pressing groove is formed between the two, and the first bolt and the second bolt are used to connect the second mounting plate and the first mounting plate together.

[0020] By adopting the technical scheme, when the seat needs to be installed, the mounting block at the bottom of the seat can be placed on the first mounting plate first, then the second mounting plate is placed on the mounting block, and the first mounting plate and the second mounting plate are locked to each other through the first bolt and the second bolt, so that the mounting block of the seat is pressed in the pressing groove, and the fixing is completed.

[0021] In a second aspect, the application further provides a bicycle, which comprises the adjusting mechanism, the upper tube, the lower tube, the front fork and the rear fork having the above structures, one end of the upper tube is connected with the seat tube, the lower tube is located below the upper tube and one end of the lower tube is connected with the seat tube, the other end of the upper tube is connected with the other end of the lower tube to form a head tube, and the front fork is arranged at the head tube; the rear fork is symmetrically arranged in a pair, and both of the rear forks are connected with the seat tube.

[0022] By adopting the technical scheme, the upper tube, the lower tube and the seat tube form a triangular structure, the triangular structure has stability, and the stability of the bicycle as a whole can be improved. The front fork is installed on the head tube, and the installation of the handlebar of the bicycle is facilitated. The rear fork is used for mounting the rear wheel.

[0023] In summary, the application has at least one of the following beneficial technical effects:

[0024] (1) By arranging the support rod and the friction block, when the height of the seat needs to be adjusted, the fastening bolt is loosened first, then an external force is applied to the support rod, so that the position of the support rod in the mounting groove is controlled, and the height of the seat relative to the ground is changed. When the support rod is adjusted to the desired position, the fastening bolt is tightened again, and the fixing of the support rod is realized by relying on the pressure, so that the stability of the height adjustment of the bicycle seat is improved.

[0025] (2) By arranging a plurality of protrusions corresponding to the same number of fastening bolts, the plurality of fastening bolts can lock the friction block together, so as to improve the firmness of the position of the support rod.

[0026] (3) By arranging the groove on the friction block, the rubber ring can be arranged in the groove, and the existence of the rubber ring can increase the friction between the friction block and the support rod. BRIEF DESCRIPTION OF DRAWINGS

[0036] Some embodiments of the present application will be described in detail below in conjunction with the drawings. Those skilled in the art can combine and combine the different embodiments or examples expressed in the present application and the features of the different embodiments or examples without conflict.

[0037] The embodiments of the present application disclose a bicycle adjusting mechanism. Referring to Figure 1 and Figure 2The adjusting mechanism comprises a seat tube 1, a support rod 2 and a friction block 3. The seat tube 1 is provided with a mounting groove 4 along the length direction of the seat tube 1, and the support rod 2 is movably arranged in the mounting groove 4. One end of the support rod 2 is located in the mounting groove 4, and the other end is located outside the mounting groove 4. The end of the support rod 2 outside the mounting groove 4 is used for mounting a seat. A limiting groove 5 is formed on the outer side wall of the support rod 2 along the length direction of the support rod 2, and the friction block 3 is movably arranged in the limiting groove 5. One side surface of the friction block 3 is fixedly connected with a sliding block 6, and the sliding block 6 is slidably connected in the limiting groove 5.

[0038] The support rod 2 and the friction block 3 are locked on the seat tube 1 by fasteners. One side of the friction block 3 away from the sliding block 6 is integrally connected with a protrusion 7, and the protrusion 7 penetrates the seat tube 1. An installation hole 8 is formed in the protrusion 7, and the installation hole 8 is used for abutting against the fastener. In the embodiment, the fastener is a fastening bolt. One end of the fastening bolt penetrates the seat tube 1 and abuts against the installation hole 8. By screwing the fastening bolt, the friction block 3 is abutted against the support rod 2 by the fastening bolt, and the fixation of the support rod 2 is realized by the pressure, so as to limit the movement of the support rod 2 in the mounting groove 4. In the embodiment, the seat tube 1 and the support rod 2 are made of carbon fiber material. The carbon fiber material has the characteristics of light weight and high strength, and can improve the use experience and service life of the bicycle.

[0039] When the height of the seat needs to be adjusted, the fastening bolt is first loosened, and then an external force is applied to the support rod 2, so as to control the movement of the support rod 2 in the mounting groove 4, thereby changing the height of the seat relative to the ground. During the movement of the support rod 2, the protrusion 7 is limited by the seat tube 1, so as to avoid the synchronous movement of the friction block 3 with the support rod 2, that is, the relative movement between the support rod 2 and the friction block 3. When the support rod 2 is adjusted to the desired position, the fastening bolt is tightened again to fix the support rod 2.

[0040] As shown in the drawings, the friction block 3 is connected with two protrusions 7, and the two protrusions 7 are located on the same side of the friction block 3. The two protrusions 7 correspond to the same number of fastening bolts, and the two fastening bolts jointly lock the friction block 3, so as to improve the firmness of the position of the support rod 2 and reduce the possibility of movement of the support rod 2 in the mounting groove 4. In some embodiments, a groove 9 is also formed in the friction block 3, and the groove 9 is used for sleeving a rubber ring. Since the rubber ring is made of high polymer material and has a large friction coefficient, the static friction force between the friction block 3 and the support rod 2 can be increased, and the effect of preventing slipping can be achieved.

[0041] In combination with Figure 3In addition, the end of the support rod 2 outside the mounting groove 4 is provided with a mounting assembly 10 for assisting the seat to be mounted on the seat tube 1. The mounting assembly 10 comprises a first mounting plate 101, a second mounting plate 102, a first bolt 103 and a second bolt 104. The first mounting plate 101 is fixedly connected to the support rod 2, and the second mounting plate 102 is located above the first mounting plate 101 and forms a pressing groove therebetween. One end of the first bolt 103 penetrates through the seat tube 1 and is screwed on the second mounting plate 102. One end of the second bolt 104 penetrates through the second mounting plate 102 and is screwed on the seat tube 1.

[0042] When the seat needs to be mounted, the mounting block at the bottom of the seat can be placed on the first mounting plate 101 first, and then the second mounting plate 102 is placed on the mounting block, and the first mounting plate 101 and the second mounting plate 102 are locked to each other through the first bolt 103 and the second bolt 104, so that the mounting block of the seat is pressed in the pressing groove, and the fixing is completed.

[0043] The implementation principle of the bicycle adjusting mechanism in the embodiment of the application is as follows: when the height of the seat needs to be adjusted, the fastening bolt is loosened first, then an external force is applied to the support rod 2, so that the support rod 2 is controlled to move in the mounting groove 4, thereby changing the height of the seat relative to the ground. When the support rod 2 is adjusted to the desired position, the fastening bolt is tightened again, and the fixing of the support rod 2 is realized by relying on the pressure, thereby improving the stability of the height adjustment of the bicycle seat.

[0044] Based on the above embodiment, as shown in Figure 1 The embodiment of the application also provides a bicycle, which comprises the adjusting mechanism with all the structures described above, an upper tube 11, a lower tube 12, a front fork 13 and a rear fork 14. One end of the upper tube 11 is fixedly connected to the seat tube 1, and the lower tube 12 is located below the upper tube 11 and has one end fixedly connected to the seat tube 1. The other end of the upper tube 11 is connected to the other end of the lower tube 12 and forms a head tube 15, and the front fork 13 is installed at the position of the head tube 15. The rear fork 14 is symmetrically provided with a pair of rear forks 14, and both of the rear forks 14 are connected to the seat tube 1.

[0045] The upper tube 11, the lower tube 12 and the seat tube 1 form a triangular structure, the triangular structure has stability, and the stability of the whole bicycle can be improved. The front fork 13 is installed on the head tube 15, which facilitates the installation of the handlebar of the bicycle, and the rear fork 14 is used for mounting the rear wheel.

[0046] The above are the preferred embodiments of the application, which do not limit the protection scope of the application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
