Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire air tightness testing technology, specifically a fixed fixture for tire air tightness testing. Background Technology
[0002] A bicycle, also known as a pedal bike or cyclist, is a small, two-wheeled land vehicle. When a person gets on the bike, they use their feet to pedal for power. It is a green and environmentally friendly means of transportation. When using a bicycle, the tire is an essential accessory. Bicycle tires usually consist of an outer tire and an inner tire, which are mounted on a metal rim and inflated to support the bicycle frame, cushion external impacts, and make contact with the road surface.
[0003] Currently, after repairing bicycle inner tubes, an air tightness test is required. During the test, the tire is usually held manually and placed in water, rotated little by little to find the leak point, thus checking the air tightness. This is time-consuming, labor-intensive, and reduces work efficiency. To address this, we have proposed a fixed fixture for tire air tightness testing. Utility Model Content
[0004] The purpose of this invention is to provide a fixed fixture for tire air tightness testing, in order to solve the problem that in the current technology, the tire is usually manually held and placed in water, rotated little by little to find the leak point, which is time-consuming, labor-intensive and reduces work efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed fixture for tire air tightness testing, comprising a base plate, a water tank placed on the top of the base plate, a support column fixedly connected to the top of the base plate, a lifting mechanism provided on the outer side of the support column, a drive motor fixedly connected to one side of the lifting mechanism, a fixing frame fixedly connected to one side of the lifting mechanism, the output shaft end of the drive motor penetrating through the middle of one side of the fixing frame, and a sleeve fixedly connected to the output shaft end of the drive motor, through grooves evenly provided on the outer side wall of the sleeve, and a fixing mechanism fixedly connected to one end of the sleeve.
[0006] Preferably, the fixing mechanism includes a fixed plate fixedly connected to one end of the sleeve. A servo motor is fixedly connected to the middle of one side of the fixed plate. The output shaft of the servo motor passes through one side of the fixed plate, and a screw is fixedly connected to the end of the output shaft of the servo motor. A movable plate is screwed to the outer wall of the screw. A first connecting seat is uniformly fixedly connected to the outer wall of the movable plate. A connecting rod is rotatably connected inside the first connecting seat. A sliding groove is uniformly opened on the other side of the fixed plate. A slider is slidably connected inside the sliding groove. A connecting rod is fixedly connected to the middle of the outer wall of the slider. A support block is fixedly connected to the end of the connecting rod. A second connecting seat is fixedly connected to one side of the slider.
[0007] Preferably, the first connecting seat is slidably connected to the inside of the through groove. The cooperation between the first connecting seat and the through groove limits the movement of the moving disk. When the screw rotates, the moving disk moves. A baffle is fixedly connected to the end of the screw to prevent the moving disk from falling off the screw when it moves.
[0008] Preferably, one end of the connecting rod is rotatably connected to the inside of the second connecting seat. When the connecting rod deflects, it drives the second connecting seat to move, causing the slider to slide. Both the slider and the slide groove are T-shaped to prevent the slider from dislodging from the slide groove when the slider slides.
[0009] Preferably, the connecting rod passes through the outer wall of the fixed disk, and the connecting rod is slidably connected to the fixed disk, which facilitates the connecting rod to drive the support block to move.
[0010] Preferably, the lifting mechanism includes a movable slot extending through one side of the support column, with slide rods symmetrically fixedly connected between the top and bottom of the movable slot, a movable block slidably connected to the outer wall of the slide rod, a dual-axis motor fixedly connected to the other side of the movable block, a gear fixedly connected to the output shaft end of the dual-axis motor, a rack symmetrically fixedly connected to the other side of the support column, and both the drive motor and the fixed frame fixedly connected to one side of the movable block, with the drive motor located inside the fixed frame.
[0011] Preferably, the moving block is located inside the moving groove, and the gear is meshed with the rack, so that when the gear rotates, the gear moves outside the rack.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This application utilizes a fixed mechanism. By starting a servo motor, the screw rotates, causing the moving disk to move. This, in turn, causes the first connecting seat to move, which in turn causes the connecting rod to deflect. This causes the second connecting seat to move the slider, which in turn causes the connecting rod to move the support block, thus opening and fixing the tire. Then, using a lifting mechanism, the outer side of the tire is placed in a water tank. The drive motor is started, causing the sleeve to rotate and the fixed disk to rotate, thereby rotating the tire. This allows for the detection of the tire's air tightness, facilitating tire fixation and avoiding the need for manual labor to manually search for leaks. This makes the detection more time-saving and labor-saving, improving detection efficiency.
[0014] 2. In this application, the lifting mechanism is used to drive the gear to rotate by starting the dual-shaft motor. The gear meshes with the rack. When the gear rotates, it causes the gear to descend on the rack, which in turn causes the dual-shaft motor to drive the moving block to descend, thereby lowering the tire. This allows for easy adjustment according to the tire diameter, positioning the tire in the water and improving the applicability of the lifting device. Attached Figure Description

[0023] Please see Figure 2 and Figure 3The fixing mechanism 700 includes a fixing plate 710 fixedly connected to one end of the sleeve 600. A servo motor 720 is fixedly connected to the middle of one side of the fixing plate 710. The output shaft of the servo motor 720 passes through one side of the fixing plate 710, and a screw 730 is fixedly connected to the end of the output shaft of the servo motor 720. A movable plate 740 is screwed to the outer wall of the screw 730. A first connecting seat 750 is evenly fixedly connected to the outer wall of the movable plate 740. A connecting rod 760 is rotatably connected inside the first connecting seat 750. A sliding groove 770 is evenly opened on the other side of the fixing plate 710. A slider 780 is slidably connected inside the sliding groove 770. A connecting rod 781 is fixedly connected to the middle of the outer wall of the slider 780. A support block 782 is fixedly connected to the end of the connecting rod 781. A second connecting seat 790 is fixedly connected to one side of the slider 780. The first connecting seat 750 is slidably connected to the inside of the through groove 610. A baffle is fixedly connected to the end of the screw 730. The connecting rod 760... One end of the 0 is rotatably connected to the inside of the second connecting seat 790. Both the slider 780 and the slide groove 770 are T-shaped. The connecting rod 781 passes through the outer wall of the fixed plate 710, and the connecting rod 781 is slidably connected to the fixed plate 710. With the setting of the fixing mechanism 700, the servo motor 720 is started to drive the screw 730 to rotate, causing the moving plate 740 to move, thereby causing the first connecting seat 750 to move, driving the connecting rod 760 to deflect, causing the second connecting seat 790 to drive the slider 780 to move, and then the connecting rod 781 to drive the support block 782 to move, thus opening and fixing the tire. Then, the lifting mechanism 800 is used to place the outer side of the tire in the water tank 200. The drive motor 400 is started to drive the sleeve 600 to drive the fixed plate 710 to rotate, thereby rotating the tire to test the air tightness of the tire. This makes it easier to fix the tire and avoids manually holding the tire and searching for the leak point bit by bit, thus making the test more time-saving and labor-saving, and improving the test efficiency.
[0024] Please see Figure 4 and Figure 5The lifting mechanism 800 includes a movable slot 810 extending through one side of the support column 300.

By using the lifting mechanism 800, the dual-shaft motor 840 is started to drive the gear 850 to rotate. The gear 850 meshes with the rack 860. When the gear 850 rotates, it descends on the rack 860, which causes the dual-shaft motor 840 to drive the movable block 830 to descend, thereby lowering the tire. This makes it easier to adjust according to the tire diameter, allowing the tire to be placed in the water for easy adjustment and improving the applicability of the device.
[0025] In use, this invention involves placing an inflated tire on the outside of the support block 782, starting the servo motor 720 to rotate the screw 730, causing the moving disk 740 to move, which in turn moves the first connecting seat 750, causing the connecting rod 760 to deflect, which in turn causes the second connecting seat 790 to move the slider 780, which in turn causes the connecting rod 781 to move the support block 782, thus spreading and fixing the tire. Then, starting the dual-axis motor 840 to rotate the gear 850, which meshes with the rack 860. As the gear 850 rotates, it descends on the rack 860, causing the dual-axis motor 840 to lower the moving block 830, thus lowering the tire and placing its outer side in the water tank 200. Then, starting the drive motor 400 to rotate the sleeve 600 and the fixed disk 710, thus rotating the tire and testing its air tightness.
