Description

Technical Field

[0001] This utility model relates to the field of vertical testing technology, and in particular to a vertical testing machine for shock-absorbing forks. Background Technology

[0002] The suspension fork is a crucial component on a bicycle used to reduce front wheel vibration and improve riding comfort and handling. When the bicycle's front wheel encounters bumps and impacts, the inner tube of the suspension fork compresses downwards along the outer tube. During this process, the shock-absorbing medium is compressed and stores energy. Simultaneously, the damping system kicks in, controlling the speed and force of compression to prevent over-compression of the fork. After the impact, the compressed shock-absorbing medium releases its stored energy, pushing the inner tube upwards back to its initial position. The suspension fork vertical tester is a device specifically designed to test the performance of suspension forks. It primarily simulates the vertical impacts and vibrations experienced by the fork during bicycle riding, thereby evaluating various performance indicators of the suspension fork. However, during the testing process, the fork may move as it is tested, necessitating the use of a fixing device to stabilize the fork.

[0003] The existing fixing device consists of a buckle, a slot, and a mounting bracket. When fixing a shock-absorbing fork, the fork is first placed in the appropriate position of the buckle fixing device. Since the buckle is in an open and popped-out state under the action of the spring, the fork can be inserted into the space between the buckle and the slot. Then, through manual and mechanical drive, the buckle is rotated around its connection point. The hook part of the buckle gradually approaches the slot and the insertion rod. When the hook of the buckle contacts the slot and inserts into it, the spring is further compressed. The resulting elastic force will cause the buckle to lock into the slot, thereby fixing the fork to the device. After the test, the reverse operation is performed. However, when the specifications of the fork and the test requirements are different, the buckle fixing device cannot adjust its height. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a shock-absorbing fork vertical testing machine, which aims to improve the problem that the buckle fixing device cannot adjust the height of the fork when the specifications and testing requirements are different in the existing technology.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a shock-absorbing front fork vertical testing machine, comprising a frame, with multiple rotating rods rotatably connected to the left and right sides of the frame near the middle, a worm gear fixedly connected to the left side of each rotating rod, a worm engaged with the outer wall of the worm gear, a rotating column fixedly connected to the top of the worm, a turntable fixedly connected to the top of the rotating column, multiple bevel gears fixedly connected to the middle and right sides of the outer wall of each rotating rod, bevel gears engaged with the outer wall of each bevel gear, a threaded rod fixedly connected to the inner wall of each bevel gear, a threaded sleeve threadedly connected to the outer wall of the threaded rod, a threaded hole provided on the front side of the outer wall of the threaded sleeve, and a sliding groove slidably connected to the outer wall of the threaded sleeve, and multiple disassembly mechanisms provided at the upper middle end of the frame, the disassembly mechanisms being used for disassembly and replacement.

[0006] As a further description of the above technical solution:

[0007] The disassembly mechanism includes a chassis, the bottom of which is fixedly connected to the top left and right sides of the frame. The left and right sides of the chassis have multiple square holes I. The inner wall of each square hole I is slidably connected to a rod. The other end of the rod is slidably connected to a square sleeve. The left and right ends of the rod are slidably connected to the left and right sides of the cover plate near the middle. The outer wall of the cover plate has multiple square holes II.

[0008] As a further description of the above technical solution:

[0009] A clamping plate is fixedly connected to the front side of the threaded sleeve, and a sliding groove is slidably connected to the rear side of the clamping plate.

[0010] As a further description of the above technical solution:

[0011] Multiple support columns are fixedly connected to the upper front end of the frame near the edge, and the bottom of each support column is rotatably connected to the top of the threaded rod.

[0012] As a further description of the above technical solution:

[0013] Multiple fixing blocks are fixedly connected to the top left and right ends of the cover plate, and rotating rods are rotatably connected between adjacent fixing blocks.

[0014] As a further description of the above technical solution:

[0015] A push rod is fixedly connected to the top of the second rotating rod, and a front fork sample is rotatably connected to the top of the push rod.

[0016] As a further description of the above technical solution:

[0017] An operation box is fixedly connected to the front side of the frame near the middle, and an operation panel is fixedly connected to the front side of the operation box.

[0018] As a further description of the above technical solution:

[0019] A second support column is fixedly connected to the bottom of the inner side of the frame, and a second fixing block is fixedly connected to the bottom of the second support column. The bottom of the second fixing block is fixedly connected to the bottom of the inner side of the frame.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, rotating the turntable causes the rotating column to rotate, which in turn causes the worm and worm wheel to rotate, and simultaneously causes the rotating rod one to rotate. At this time, the rotating rod one drives the bevel gear one and bevel gear two to rotate, and then drives the threaded rod to rotate, causing the threaded sleeve to move up and down. At this time, the clamping plate moves up and down, thus achieving the effect of adjusting the clamping fixture up and down according to the front fork and testing requirements.

[0022] 2. In this utility model, when the push rod needs to be replaced, the square sleeve is removed from the insert rod, and then the insert rod is taken out through the square hole one on the chassis and the square hole two on the cover plate. At this time, the push rod is picked up and the new push rod is placed on it. Similarly, when the push rod is worn and needs to be replaced and cleaned, it can be quickly removed for operation.
