Description

Technical Field

[0001] This utility model relates to the field of bicycle manufacturing technology, and in particular to an adjustable bicycle assembly device. Background Technology

[0002] A bicycle, also known as a pedal bike or cyclist, is typically a small, two-wheeled land vehicle. Riders power it by pedaling, making it a green and environmentally friendly mode of transportation. It can be used for commuting and getting around in an eco-friendly way; increasingly, people are also using bicycles as fitness equipment for exercise and cycling trips.

[0003] When assembling a bicycle, small structural components such as the saddle, pedals, and handlebars need to be installed on the frame. Additionally, the wheels need to be assembled, including the rim, spokes, hub, and axle. During assembly, the rim needs to be rotated constantly to ensure a reliable connection between the rim and hub via the spokes, while also preventing deformation of the rim's circular profile and avoiding excessive runout during rotation. However, existing bicycle rims cannot be rotated for position adjustment during assembly, making assembly inconvenient, time-consuming, and labor-intensive, thus reducing assembly efficiency. Therefore, this application discloses an adjustable bicycle assembly device. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing an adjustable bicycle assembly device.

[0005] This utility model is achieved through the following technical solution: an adjustable bicycle assembly device, including a frame, a ring rail installed on the frame, several rollers arranged circumferentially on the ring rail, the rollers connected to the lower surface of a ring plate, a disc frame connected inside the ring plate, the lower surface of the disc frame connected to the output shaft of a motor, the motor installed at the top inside the frame, a vertical shaft connected vertically in the middle of the disc frame through a pad, a hole arranged circumferentially and through the ring rail, a tube of a lifting mechanism connected below the hole, a top rod of the lifting mechanism vertically connected to a top frame, the top frame supported and connected to the frame through a hydraulic cylinder, and several clamping mechanisms installed on the ring plate.

[0006] As a further improvement to the above solution, the lifting mechanism includes a tube, the upper end of which is concentrically connected to the lower end of the hole. A stepped hole is provided at the upper end of the tube, and a ball is clamped at the upper end of the tube through the stepped hole. A spring and a push rod are sequentially installed inside the tube below the ball.

[0007] The upward displacement of the push rod pushes the spring, which in turn pushes the ball out of the hole on the ring track to prevent the roller from rolling in the hole. In addition, the spring slows down the rapidly rotating roller until it comes to a stop. The roller rolls and crushes the ball on the ring track, and the spring acts as a buffer and deceleration mechanism.

[0008] As a further improvement to the above solution, guide rods are slidably installed on both ends of the top frame, and the guide rods are vertically connected to the frame.

[0009] The guide rod is used to balance the top frame during the lifting and lowering process caused by the hydraulic cylinder, ensuring the smooth and balanced displacement of the top frame.

[0010] As a further improvement to the above solution, the clamping mechanism includes a waist groove, which is installed on the ring plate and extends to the plate frame. A support rod is inserted into the waist groove, the upper end of the support rod is connected to an L-shaped clamping block, the lower end of the support rod is connected to an end plate, and a spring is fitted on the support rod between the end plate and the lower edge of the waist groove.

[0011] The L-shaped clamping block is adjusted by sliding the strut in the groove to accommodate different sizes of wheel rims. The L-shaped clamping block is placed above the wheel rim, and the spring on the strut pulls the L-shaped clamping block to clamp the wheel rim onto the ring plate and / or the disc frame.

[0012] As a further improvement to the above solution, a ring sleeve is fitted onto the outer edge of the ring rail;

[0013] By fitting a ring around the outer edge of the ring rail, the ring guides and limits the rollers that are moving in a circular motion, preventing the rollers from rolling off the ring rail.

[0014] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The hub is placed on a pad, so that the hub is fitted outside the column. At the same time, the rim is placed on the ring plate. The spokes connect the rim and the hub. The motor rotates at low speed, which makes it easy to adjust the displacement and install the spokes. The spokes make the hub and the rim an integral structure and ensure that the rim will not warp. The edge of the rim is attached to the ring plate. In addition, the hydraulic cylinder drives the ball to rise and protrude out of the hole, so that the roller rolls and the rim placed on it are stationary, which facilitates the assembly of the wheel.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown, an adjustable bicycle assembly device includes a frame 1, on which a ring rail 2 is mounted. Several rollers 3 are arranged circumferentially on the ring rail 2. The rollers 3 are connected to the lower surface of a ring plate 4. A disc frame 5 is connected inside the ring plate 4. The lower surface of the disc frame 5 is connected to the output shaft of a motor 6. The motor 6 is mounted on the top inside the frame 1. A vertical shaft 8 is vertically connected to the middle of the disc frame 5 through a pad 7. A hole 22 is provided circumferentially and through the ring rail 2. A tube 15 of a lifting mechanism 12 is connected below the hole 22. The top rod 13 of the lifting mechanism 12 is vertically connected to a top frame 10. The top frame 10 is supported and connected to the frame 1 through a hydraulic cylinder 9. Several clamping mechanisms 18 are mounted on the ring plate 4.

[0021] As a further improvement to the above solution, the lifting mechanism 12 includes a tube 15, the upper end of which is concentrically connected to the lower end of the hole 22. A stepped hole 17 is provided at the upper end of the tube 15, and a ball 16 is clamped at the upper end of the tube 15 through the stepped hole 17. A spring 14 and a push rod 13 are sequentially installed inside the tube 15 below the ball 16.

[0022] The push rod 13 moves upward, pushing the spring 14. The spring 14 then elastically pushes the ball 16 out of the hole 22 on the ring rail 2 to block the roller 3 from rolling at the hole 22. In addition, the spring 14 slows down the rapidly rotating roller 3 until it comes to a stop. The roller 3 rolls and crushes the ball 16 on the ring rail 2, and the spring 14 plays a buffering and deceleration role.

[0023] As a further improvement to the above solution, guide rods 11 are slidably and continuously provided on both ends of the top frame 10, and the guide rods 11 are vertically connected to the frame 1.

[0024] The guide rod 11 is used to balance the top frame 10 during the lifting and lowering process under the action of the hydraulic cylinder 9, so as to ensure the smooth and balanced displacement of the top frame 10.

[0025] As a further improvement to the above solution, the clamping mechanism 18 includes a waist groove 19, which is installed on the ring plate 4 and extends to the plate frame 5. A support rod 20 is inserted into the waist groove 19. The upper end of the support rod 20 is connected to an L-shaped clamping block 21, and the lower end of the support rod 20 is connected to an end plate 22. A spring 23 is fitted on the support rod 20 between the end plate 22 and the lower edge of the waist groove 19.

[0026] The support rod 20 slides within the waist groove 19 to adjust the distance between the L-shaped clamping block 21 and the axis of the ring plate 4, so as to accommodate different specifications of wheel rims. The L-shaped clamping block 21 is placed above the wheel rim, and the L-shaped clamping block 21 is pulled by the force of the spring 23 on the support rod 20 to clamp the wheel rim onto the ring plate 4 and / or the disc frame 5.

[0027] As a further improvement to the above scheme, a ring sleeve 21 is fitted onto the outer edge of the ring rail 2;

[0028] The ring 21 is sleeved on the outer edge of the ring rail 2, and the ring 21 is used to guide and limit the roller 3 in the annular displacement, so as to prevent the roller 3 from rolling away from the ring rail 2.

[0029] The working principle of an adjustable bicycle assembly device: The hub is placed on the pad plate 7, so that the hub is fitted outside the column. At the same time, the rim is placed on the ring plate 4. The spokes connect the rim and the hub. The motor 6 rotates at low speed, which facilitates the adjustment of displacement and the installation of spokes. The spokes make the hub and rim a single structure and ensure that the rim does not warp. The edge of the rim is attached to the ring plate 4. In addition, the hydraulic cylinder 9 drives the ball 16 to rise and protrude from the hole 22, so that the roller 3 is obstructed from rolling, so that the ring plate 4 and the rim placed on it are stationary, which facilitates the assembly of the wheel.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
