Description

[Technical Field]

[0001] This invention relates to the field of bicycle repair equipment, and in particular to a bicycle repair rack control device with a 360-degree swivel structure, which improves the convenience and efficiency of bicycle repair. [Previous Technology]

[0002] The bicycle repair racks commonly found on the market are designed specifically for bicycle repair and maintenance. They typically consist of a pole as a support column, with a retractable tripod at the bottom of the support column and a clamp above the support column to hold the bicycle in the air for support. This design allows repair personnel to flexibly adjust the angle of the bicycle as needed, thus facilitating various repair operations.

[0003] Conventional bicycle repair racks, such as the utility model patent No. M491610 "Improved Angle Fixing Structure of Bicycle Repair Rack", include a clamp comprising: a horizontal movable sleeve, a movable clamping seat, and an adjustment device. The movable clamping seat is connected to the front end of the horizontal movable sleeve, and the adjustment device is connected to the rear end of the horizontal movable sleeve. The movable clamping seat has a rotation function and can be used to clamp the bicycle frame or fork. The adjustment device is pivotally mounted with a control handle. When it is necessary to position the movable clamping seat, rotating the control handle downwards will control the movable clamping seat to be in a positioned state. When the movable clamping seat needs to be rotated at an angle, rotating the control handle upwards will push the movable clamping seat forward through a compression reset member, thereby controlling the movable clamping seat to be in a rotatable state, providing the bicycle with angle adjustment during repair.

[0004] However, in this conventional bicycle repair frame, when the movable clamp is positioned, the control handle is fixed at a vertically downward angle. This makes it easy for repair personnel to be restricted in their standing position when performing bicycle repairs, causing the control handle to be obstructed by the horizontal movable tube and support column. This makes it difficult for repair personnel to easily rotate the handle upward to release the positioning of the movable clamp. Furthermore, after rotating and adjusting to the required angle, it is also difficult to rotate the control handle downward to reposition the movable clamp, thus affecting the convenience of use. [Summary of the Invention]

[0005] In view of the above-mentioned shortcomings of conventional bicycle repair racks, the inventor conceived the idea of ​​creation, and after extensive research, trial production and testing, and multiple revisions and improvements, finally launched this invention.

[0006] This invention provides a 360-degree swivel structure for a bicycle repair rack control device. The bicycle repair rack includes a support column and a set of clamps mounted on the support column. The clamps include: a connector with a sleeve that is connected to the support column. The sleeve has a front end and a rear end, and the front end has a first positioning part; a clamping mechanism located at the front end of the sleeve, one end of which has a transmission rod and a second positioning part. The transmission rod passes through the sleeve, and the second positioning part can be controlled to engage or disengage from the first positioning part; and a control device located at the rear end of the sleeve. The control device includes a rotating seat and a control handle. The rotating seat is rotatably mounted on the rear end of the sleeve. The control handle is pivotally connected to the rotating seat and to the transmission rod of the clamping mechanism, allowing the control handle to rotate with the rotating seat. The control handle can pivot between an open position and a locked position. A safety device is provided on the control handle. When the control handle is in the locked position, the safety device engages with the rotating seat, preventing rotation between the receiving seat and the clamping mechanism, while allowing rotation between the control device, the receiving seat, and the clamping mechanism. When the control handle is in the open position, rotation between the receiving seat and the clamping mechanism is allowed, as is rotation between the control device, the receiving seat, and / or the clamping mechanism. At least one damping means is provided between the receiving seat and / or the clamping mechanism and the control device.

[0007] The main purpose of the 360-degree rotating structure of the bicycle repair rack control device of the present invention is that, when in use, the control handle can be rotated to a convenient operating angle according to the standing position of the repairman, thereby avoiding the operational difficulties caused by space limitations and improving the flexibility and convenience of the repair process.

[0008] Another objective of the 360-degree swivel structure of the bicycle repair rack control device of the present invention is that a safety device is provided on its control handle. When the control handle is in the locked position, the safety device can prevent the control handle from being opened accidentally, thus ensuring safety during use.

Implementation Method

[0009] The following description, in conjunction with the drawings of the preferred embodiments of the present invention, is intended to enable those skilled in the art to implement the invention based on the statements in this specification.

[0010] First, as shown in Figures 1 to 5, the bicycle repair rack control device of the present invention has a 360-degree swivel structure. The bicycle repair rack includes a support column 1 and a set of clamps 2 disposed above the support column 1. The clamps 2 include: a connector 10, a clamping mechanism 20 and a control device 30.

[0011] The connector 10 is provided with a transverse sleeve 11. A set of connecting parts 12 extends downward from the periphery of the sleeve 11 for connecting to the upper end of the support column 1. The sleeve 11 has a front end 111 and a rear end 112. The front end 111 is provided with a first positioning part 13. In this embodiment, the sleeve 11 is provided with at least one protruding limiting member 113. The first positioning part 13 is a ring-shaped first toothed part, which is disposed at one end of a connecting member 14. The connecting member 14 is fitted and fixed to the front end 111 of the sleeve 11.

[0012] The clamping mechanism 20 is disposed at the front end 111 of the sleeve 11 and is used to clamp the bicycle frame or fork, suspending and supporting the bicycle. One end of the clamping mechanism 20 is provided with a transmission rod 21 and a second positioning part 22. The transmission rod 21 passes through the sleeve 11, and the second positioning part 22 can engage or disengage with the first positioning part 13. The clamping mechanism 20 is spring-loaded by a return element 23. In this embodiment, the end of the transmission rod 21 away from the clamping mechanism 20 is provided with a screw hole 211, and the transmission rod 21 passes through the sleeve 14. The second positioning part 22 is a ring-shaped second toothed part. The return element 23 is a spring, sleeved on the transmission rod 21, and spring-loaded between the clamping mechanism 20 and the sleeve 14.

[0013] The control device 30 is located at the rear end 112 of the sleeve. The control device 30 includes a rotating base 31 and a control handle 32. The rotating base 31 is rotatably mounted on the rear end 112 of the sleeve 11. The control handle 32 is pivotally connected to the rotating base 31 and to the transmission rod 21 of the clamping mechanism 20, so that the control handle 32 can rotate with the rotating base 31. At the same time, the control handle 32 can pivot between the open position 32A (refer to Figures 7 to 9) and the locked position 32B (refer to Figures 1, 5, 6, 10 and 11). The control handle 32 is provided with a safety device 33. When the control handle 32 is in the locked position 32B, the second positioning part 22 engages with the first positioning part 13 to control the clamping mechanism 20 to form a positioning state. At the same time, the safety device 33 can be engaged with the rotating base 31 to prevent the control handle 32 from being opened accidentally. In this embodiment, the control device 30 further includes a first wear-resistant element 34, a pivot member 35, a screw 36, and a second wear-resistant element 37. The rotating seat 31 has a limiting annular groove 311 and a latching hole 312 around its periphery. The limiting annular groove 311 allows the limiting member 113 to extend into it, restricting the rotating seat 31 to rotate but not move. The rotating seat 31 has a rod hole 313 inside for the transmission rod 21 to pass through, located away from the sleeve 1. One end of the control handle 32 has a pivot groove 314 communicating with the rod hole 313. One end of the control handle 32 has a pivot hole 321, and one side has a slot 322. The safety device 33 includes a safety buckle 331 and a reset member 332. The safety buckle 331 is pivotally mounted in the slot 322 and has a hook 3311 for engaging the buckle hole 312. The reset member 332 is located between the safety buckle 331 and the slot 322, for... The safety buckle 331 is spring-loaded. The first wear-resistant element 34 is disposed between the rotating seat 31 and the sleeve 14. The rotating seat 31 engages with the sleeve 14 through the first wear-resistant element 34. The first wear-resistant element 34 can be a thrust needle roller bearing, but is not limited thereto. The pivoting member 35 is cylindrical and rotatably fitted into the pivot hole 321 of the control handle 32, and pivotally connected within the pivot groove 314 of the rotating seat 31. The screw... 36 passes through the pivot 35 and is screwed and fixed to the screw hole 211 of the transmission rod 21. The second wear-resistant element 37 is disposed between the head of the screw 36 and the pivot 35. The second wear-resistant element 37 can be a Teflon gasket, but is not limited thereto. The first wear-resistant element (34) and the second wear-resistant element (37) are damping means. The damping means is disposed between the connector 10 and / or the clamping mechanism 20 and the control device 30.

[0014] When performing bicycle repair, if it is necessary to adjust the angle of the bicycle clamped by the clamping mechanism 20, as shown in Figure 6, first press the safety buckle 331 of the safety device 33 to compress the reset member 332. The buckle hook 3311 of the safety buckle 331 disengages from the buckle hole 312 of the rotating seat 31. Then, as shown in Figure 7, turn the control handle 32 from the locked position 32B to the open position 32A. This causes the clamping mechanism 20 to be displaced a certain distance by the return element 23, resulting in the separation of the second positioning part 22 of the clamping mechanism 20 from the first positioning part 13 of the receiving seat 10. The receiving seat 10 and the clamping mechanism 20 can rotate together. The timing control device 30 can rotate with the connector 10 and / or the clamping mechanism 20. Then, as shown in Figures 8 and 9, the clamping mechanism 20 is operated to rotate and adjust the bicycle to the required angle. Then, as shown in Figures 10 and 11, after the adjustment is completed, the control handle 32 is turned from the open position 32A back to the locked position 32B. The control handle 32 pulls the clamping mechanism 20 through the transmission rod 21, so that the second positioning part 22 of the clamping mechanism 20 and the first positioning part 13 of the connector 10 are re-engaged. The connector 10 and the clamping mechanism 20 cannot rotate, thereby restoring the positioning state of the clamping mechanism 20 and fixing the angle of the bicycle.

[0015] As shown in Figures 12 and 13, when the control handle 32 is in the locked position 32B, the control device 30 can rotate with the receiving seat 10 and / or the clamping mechanism 20, so that the maintenance personnel can rotate the control handle 32 360 degrees according to their own standing position to rotate it to the most convenient operating angle. The control handle 32 rotates together with the rotating seat 31 and the pivot 35, thereby ensuring that the maintenance personnel can easily operate the control handle 32 when in the maintenance position and avoid being blocked by the receiving seat 10 and the support column 1.

[0016] The following benefits can be obtained from the structure of the above specific embodiments:

[0017] 1. The bicycle repair rack control device of the present invention has a 360-degree swivel structure. When in use, the control handle 32 can be freely rotated 360 degrees to the most convenient operating angle according to the standing position of the repairman, thereby effectively avoiding the operational difficulties caused by space limitations. It not only improves the flexibility and convenience of the repair process, but also significantly improves work efficiency.

[0018] 2. The bicycle repair rack control device of the present invention has a 360-degree swivel structure. A safety device 33 is provided on its control handle 32. When the control handle 32 is in the locked position 32B, the safety device 33 can effectively prevent the control handle 32 from being opened accidentally, ensuring safety during use, avoiding accidents caused by improper operation, and enabling maintenance personnel to work in a safer environment.
