Description

[Technical field]

[0001] The utility model relates to the technical field of fitness equipment, in particular to a dynamic bicycle with a seat tube or handrail tube that is locked in both directions. [Background Technology]

[0002] Currently, the seat tube, armrest tube and machine of the exercise bikes on the market are locked with a single-sided thread. When consumers of different heights adjust the height before using the machine, they need to loosen the screws first before adjusting the height, and the adjustment is relatively cumbersome. [Utility Model Content]

[0003] The purpose of the present utility model is to solve the above-mentioned shortcomings and provide a spinning bike with a seat tube or armrest tube with two-way locking, which can achieve locking or loosening by protruding different heights of the cam at different angles, making it convenient for consumers of different heights to adjust the height direction.

[0004] To achieve the above objectives, a spinning bike with a bidirectionally locking seat tube or handrail tube is designed, comprising a machine connecting tube 1 and a bicycle seat tube / handrail tube 2 telescopically connected to the machine connecting tube 1. Notches are provided on both left and right sides of the machine connecting tube 1, each containing a rubber block group. A cam wrench 8 is provided in one of the notches and is rotatably mounted on the machine connecting tube 1. The cam wrench 8 locks or loosens the bicycle seat tube / handrail tube 2 by varying the height of the cam protruding at different angles. A linkage U-shaped seat 9 is provided in the other notch and an adjusting bolt 10 is mounted on the linkage U-shaped seat 9. The linkage U-shaped seat 9 is connected to the cam wrench 8.

[0005] Furthermore, the linkage U-shaped seat 9 is in a U-shaped structure, and a long hole is provided on the linkage U-shaped seat 9. The linkage U-shaped seat 9 passes through the machine connecting tube 1 and is connected with the boss hole on the cam wrench 8 through the long hole, so that the cam wrench 8 can drive the linkage U-shaped seat 9 to move left or right, so that the bicycle seat tube (handrail tube) is loosened or squeezed by the rubber blocks on the left and right sides.

[0006] Furthermore, the linkage U-shaped seat 9 is locked in the boss hole on the cam wrench 8 through the gasket 6 and the hexagonal bolt 7, further ensuring the stability of its linkage structure.

[0007] Furthermore, a wrench fixing bracket 11 is fixed on the machine connecting pipe 1, and a fixed shaft mounting hole 12 is opened on the wrench fixing bracket 11. The cam wrench 8 is rotatably mounted on the fixed shaft mounting hole 12 through the cam wrench fixing shaft 3, further ensuring the firmness of the cam wrench 8 mounting structure.

[0008] Furthermore, the rubber block group includes a rubber block 4 and a rubber block fixing frame 5. The rubber block 4 is press-fitted into the rubber block fixing frame 5. An adhesive coating is provided between the rubber block 4 and the rubber block fixing frame 5, thereby having better cushioning and anti-slip properties.

[0009] Furthermore, when the cam wrench 8 is lifted upward, the smallest diameter of its cam contacts the rubber block 4. A gap is provided between the rubber block 4 and the bicycle seat tube / handrail tube 2. The bicycle seat tube / handrail tube 2 is loosened to adjust the height of the bicycle by raising or lowering.

[0010] Furthermore, when the cam wrench 8 is pressed downward, the maximum diameter of its cam pushes the rubber block 4 toward the bicycle seat tube / handrail tube 2, and the rubber block 4 is tightly squeezed against the bicycle seat tube / handrail tube 2, and the bicycle seat tube / handrail tube 2 is squeezed and locked by the rubber block 4.

[0011] Compared with the prior art, the present invention provides a spinning bike with a two-way locking seat tube (handrail tube). A two-way linkage mechanism is added to the main frame, which can be locked or loosened at different angles by a cam mechanism, so as to facilitate height adjustment for consumers of different heights. In addition, the present invention achieves locking or loosening by varying the protrusion height of the cam mechanism at different angles, so as to move the tube closer to or further away from the movable tube. The adjustment is very quick and firm, avoiding the problem of cumbersome adjustment existing in traditional spinning bikes that rely on unilateral threaded locking.

[Specific implementation method]

[0019] As shown in the accompanying drawings, the present invention provides a spinning bike with a two-way locking seat tube or handrail tube, comprising a machine connecting tube 1 and a bicycle seat tube / handrail tube 2 telescopically connected to the machine connecting tube 1. Notches are provided on both left and right sides of the machine connecting tube 1, and rubber block groups are installed in the notches. A cam wrench 8 is provided at one of the notches, and the cam wrench 8 is rotatably mounted on the machine connecting tube 1. The cam wrench 8 locks or loosens the bicycle seat tube / handrail tube 2 by varying the height of the cam protruding at different angles. A linkage U-shaped seat 9 is provided at the other notch, and an adjusting bolt 10 is installed on the linkage U-shaped seat 9. The adjusting bolt 10 points to the rubber block group in the notch, and the linkage U-shaped seat 9 is connected to the cam wrench 8.

[0020] The linkage U-shaped seat 9 is a U-shaped structure with an elongated hole. The linkage U-shaped seat 9 passes through the machine connecting tube 1 and is connected to the boss hole on the cam wrench 8 through the elongated hole. This allows the cam wrench 8 to drive the linkage U-shaped seat 9 to move left or right, thereby loosening or squeezing the bicycle seat tube (handrail tube) by the rubber blocks on the left and right sides. The linkage U-shaped seat 9 is locked in the boss hole on the cam wrench 8 via a gasket 6 and a hexagonal bolt 7, further ensuring the stability of its linkage structure. A wrench fixing bracket 11 is fixed to the machine connecting tube 1, and the wrench fixing bracket 11 has a fixed shaft mounting hole 12. The cam wrench 8 is rotatably mounted in the fixed shaft mounting hole 12 via the cam wrench fixing shaft 3, further ensuring the stability of the cam wrench 8 installation structure. The rubber block assembly includes a rubber block 4 and a rubber block fixing frame 5. The rubber block 4 is press-fitted into the rubber block fixing frame 5. An adhesive coating is provided between the rubber block 4 and the rubber block fixing frame 5, thereby providing better cushioning and anti-slip properties.

[0021] When the cam wrench 8 is lifted upward, the smallest diameter of its cam contacts the rubber block 4, and a gap is provided between the rubber block 4 and the bicycle seat tube / handrail tube 2, so that the bicycle seat tube / handrail tube 2 is loosened to adjust the height of the bicycle seat tube / handrail tube 2; when the cam wrench 8 is pressed downward, the largest diameter of its cam pushes the rubber block 4 toward the bicycle seat tube / handrail tube 2, so that the rubber block 4 and the bicycle seat tube / handrail tube 2 are tightly squeezed, and the bicycle seat tube / handrail tube 2 is squeezed and locked by the rubber block 4.

[0022] The present invention provides a dynamic bicycle with a bidirectionally locked seat tube (handrail tube). The structure comprises a machine connecting tube, a bicycle seat tube (handrail tube), a cam wrench fixing shaft, a rubber block, a rubber block fixing frame, a gasket, an M5 hexagonal bolt, a cam wrench, a linkage U-shaped seat, and an adjustment bolt. First, the rubber block is coated with adhesive and pressed into the rubber block fixing frame. The rubber block assembly, which has been bonded and assembled, is then installed into the notches of the machine connecting tube. The cam wrench is then fixed to the machine connecting tube via the cam wrench fixing shaft. The linkage U-shaped seat is then passed through the machine connecting tube. When the elongated hole in the linkage U-shaped seat is aligned with the boss hole in the cam wrench, the linkage U-shaped seat is locked into the boss hole in the cam wrench using an M5 hexagonal bolt and gasket. Finally, the adjustment bolt is locked into the linkage U-shaped seat. This dynamic bicycle with a two-way locking seat tube (handrail tube) has a two-way linkage device added to the main frame, which can be locked or loosened at different angles through the cam, making it convenient for consumers of different heights to adjust the height direction. Figure 4 The figure shows the installation diagram of the present invention, wherein position Ⅰ is used for locking and adjusting the seat tube and the machine up and down, and position Ⅱ is used for locking and adjusting the armrest tube and the machine up and down.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] When the cam wrench 8 is lifted upward, the smallest diameter of the cam contacts the right rubber block 4, disengaging the rubber block 4 from the bicycle seat tube / handrail tube 2 (a gap exists between the bicycle seat tube / handrail tube 2 and the rubber block 4). In this state, the cam wrench 8 drives the linked U-shaped seat 9 to move leftward, disengaging the rubber block 4 from the bicycle seat tube / handrail tube 2. The bicycle seat tube / handrail tube 2 has no locking force and can be raised or lowered to adjust the height. If the bicycle seat tube / handrail tube 2 still interferes with the height adjustment, simply turn the adjustment bolt 10 outward slightly.

[0025] When cam wrench 8 is pressed downward, the cam's maximum diameter pushes the right rubber block 4 toward the bicycle seat tube / handrail tube 2, and the rubber block 4 is now tightly pressed against the bicycle seat tube / handrail tube 2 (the bicycle seat tube / handrail tube 2 and the rubber block 4 are squeezed, and the rubber block 4 is deformed under the force). In this state, cam wrench 8 drives the linked U-shaped seat 9 to move rightward, and the rubber block 4 and the bicycle seat tube / handrail tube 2 are also squeezed. The bicycle seat tube / handrail tube 2 is tightly squeezed by the rubber blocks 4 on both sides, and is firmly locked. At this time, if the bicycle seat tube / handrail tube 2 still has slight wobble or tends to slide up during use, the adjustment bolt 10 can be screwed inward slightly.
