Description

Technical Field

[0001] This utility model belongs to the technical field of children's vehicle repair equipment, specifically relating to a special device for disassembling snap-fit ​​connected children's vehicle wheel sets. Background Technology

[0002] Currently, most children's bicycle wheel sets use a structure where the two ends of the connecting rod are snapped into the mounting base at the bottom of the bicycle frame. While this structure is convenient to assemble, it requires manual prying to separate during maintenance and replacement, which has the following drawbacks: 1. Forceful operation can easily damage the bicycle frame structure and the snap-fit; 2. High static friction makes manual disassembly extremely labor-intensive; 3. Lack of specialized tools leads to low disassembly efficiency, making it difficult to meet the needs of batch repairs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a specialized disassembly device that can efficiently separate the body and wheel assembly of a children's bicycle, enabling mechanized disassembly operations.

[0004] This utility model provides a child bicycle wheel assembly disassembly device, including a frame, a first cylinder, a second cylinder, a pressure block, a push block, a left wheel positioning fixture, and a right wheel positioning fixture. The frame is composed of a vertical support plate and a horizontal base plate, which are fixedly connected by several columns. The first cylinder is fixedly mounted on the vertical support plate in a vertical direction. The pressure block is rigidly connected to the output end of the first cylinder and is used to press the connecting rod of the wheel assembly. The second cylinder is fixedly mounted on the vertical support plate in a vertical direction. The push block is rigidly connected to the output end of the second cylinder and is used to apply a separation force to the vehicle body. The left wheel positioning fixture and the right wheel positioning fixture are symmetrically arranged on the horizontal base plate, and their positions are adjustable. Each fixture is provided with a first C-shaped positioning groove and a second C-shaped positioning groove, and the opening direction of the first C-shaped positioning groove and the second C-shaped positioning groove is perpendicular to the direction of the push force.

[0005] As a further embodiment of this invention, the horizontal base plate is provided with a vehicle body positioning protrusion to limit the horizontal displacement of the vehicle body.

[0006] As a further embodiment of this invention, the bottom of the left wheel positioning fixture is provided with a left slider, and the bottom of the right wheel positioning fixture is provided with a right slider. The horizontal base plate is provided with a first sliding groove and a second sliding groove that cooperate with the left and right sliders, and is fixed by bolts. This allows for adjustment of the distance between the left and right wheel positioning fixtures to accommodate different models of children's vehicles, thus ensuring compatibility with multiple product specifications.

[0007] As a further embodiment of this invention, the first cylinder and the second cylinder are cylinders with adjustable stroke, and are connected to the air source control system via solenoid valves.

[0008] Disassembly procedure for using this utility model:

[0009] 1. Place the stroller on its back and insert the wheels on both sides of the damaged wheel assembly into the first C-shaped positioning groove and the second C-shaped positioning groove of the left wheel positioning fixture and the right wheel positioning fixture, respectively.

[0010] 2. Start the first cylinder, and the pressure block presses down to lock the connecting rod;

[0011] 3. Start the second cylinder, and push the pusher block vertically down to push the vehicle body until the latches separate;

[0012] 4. Reset the first and second cylinders and remove the separated wheel assembly.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Mechanized operation: Dual cylinders provide controllable separation force, avoiding damage to the vehicle body;

[0015] 2. Precise positioning: C-shaped positioning grooves constrain the wheels, and pressure blocks suppress the movement of the connecting rods;

[0016] 3. Multi-specification compatibility: Adjustable fixture spacing adapts to different wheelbase models;

[0017] 4. Increased efficiency: Separation can be completed in ≤10 seconds per operation, which is more than 5 times more efficient than manual operation. Attached Figure Description
