DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0031] Reference Figure 1-Figure 4 , an antistatic polyurethane wheel, comprising a wheel body 1, the number of the wheel bodies 1 is set to two, a mounting frame 2 is arranged between the two wheel bodies 1, both ends of the mounting frame 2 are provided with empty grooves 4, and one side of each wheel body 1 is provided with a support assembly;
[0032] The support assembly includes a driving unit and a supporting unit. The driving unit includes a handle 10. The interior of each empty slot 4 is rotatably connected to a first rotating rod 5. The outer wall of each first rotating rod 5 is fixedly connected to a supporting frame 13. Each wheel body 1 is located at the bottom of the corresponding supporting frame 13. The support unit includes a supporting seat 3. The number of the supporting seats 3 is set to two. Each handle 10 is used to control the corresponding supporting seat 3 for rotational support and fixation.
[0033] Reference Figure 1-Figure 4 Each support seat 3 is located on one side of the corresponding wheel body 1, and each empty slot 4 is rotatably connected to the inside of a second rotating rod 7, and each handle 10 is fixedly connected to one end of the corresponding second rotating rod 7, and a pawl 8 is fixedly connected to the outer wall of each second rotating rod 7, and a limit spring 9 is fixedly connected to the inside of each empty slot 4, and each limit spring 9 is fixedly connected to one side of the corresponding pawl 8, and a ratchet 6 is fixedly connected to the outer wall of each first rotating rod 5, and one end of each pawl 8 matches the outer wall of the corresponding ratchet 6, and a sliding rod 23 is slidably connected to the outer wall of each second rotating rod 7, and a plurality of sockets 22 are opened inside each ratchet 6, and one end of the sliding rod 23 is plugged into one of the sockets 22.
[0034] The support mode can be switched by the support assembly. The specific operation method is that when it is necessary to switch from the support of the wheel body 1 to the support of the support seat 3, the sliding rod 23 is first disengaged from the socket 22, and the first rotating rod 5 is rotated 90 degrees counterclockwise. At this time, the support seat 3 will replace the wheel body 1 support. Since the pawl 8 is stuck in the teeth of the ratchet 6 under the action of the limit spring 9, the sliding rod 23 is inserted into the corresponding socket 22 for further fixation, thereby realizing the fixation of the support seat 3. When it is necessary to switch from the support seat 3 to the wheel body 1 support, the sliding rod 23 is first disengaged from the socket 22, and the handle 10 is rotated in the opposite direction to drive the pawl 8 to disengage from the ratchet 6, so that the support seat 3 is fixed. The ratchet 6 and the first rotating rod 5 can rotate in opposite directions, and then the sliding rod 23 can be inserted into the corresponding socket 22 for further fixation, so as to retract the support seat 3 and restore the supporting state of the wheel body 1. Through the setting of the polyurethane wheel support assembly, not only can convenient and flexible switching between the support of the wheel body 1 and the support of the support seat 3 be achieved to adapt to different usage scenarios and needs, but also through the cooperation of the pawl 8 and the ratchet 6 and the dual fixing mechanism of the sliding rod 23 and the socket 22, the stability, reliability and safety of the supporting state are greatly enhanced, which effectively prevents accidental shaking, displacement or unlocking, and ensures the accuracy and smoothness of the operation.
[0035] Reference Figure 3A hollow rod 17 is fixedly connected to one side of each support frame 13, and the interior of each hollow rod 17 is slidably connected to the top of the corresponding support seat 3. A plurality of extension rods 18 are provided on the top of each hollow rod 17 and the support seat 3, and two of the extension rods 18 are provided with insertion rods 19 inside. Through the sliding connection between the hollow rod 17 and the support seat 3 and the cooperation between the extension rod 18 and the insertion rod 19, the overall height can be conveniently adjusted to adapt to different usage scenarios and needs, and better adapt to contact surfaces or work requirements of different heights.
[0036] Reference Figure 1-Figure 3 Both ends of the mounting frame 2 are fixedly connected with fixing plates 11, and a sponge block 12 is provided at the bottom of each fixing plate 11. The fixing plate 11 can limit the wheel body 1 during rotation, and the sponge block 12 can protect the support frame 13.
[0037] Reference Figure 5 Each support frame 13 is provided with a slide groove 15 on both sides, and each wheel body 1 is provided with a side plate 14 on both sides. The top sides of each side plate 14 are slidably connected to the corresponding slide groove 15 respectively, and two shock-absorbing springs 16 are fixedly connected between the top of each side plate 14 and the inner wall of the corresponding support frame 13. Through the sliding connection between the side plate 14 and the slide groove 15 and the setting of the shock-absorbing spring 16, the wheel body 1 can remain relatively stable during the movement, reduce shaking and deviation, and play a shock-absorbing role.
[0038] Reference Figure 1-Figure 3 The outer wall of the wheel body 1 is provided with an antistatic coating 20, and the antistatic coating 20 is made of carbon fiber material. The bottom of the support seat 3 is provided with an anti-slip pad 21, and the anti-slip pad 21 is made of elastic material. The carbon fiber has good conductivity and can quickly and effectively conduct static electricity to reduce the risks caused by static electricity accumulation. The elastic material can increase the friction with the ground to prevent the wheel body 1 from slipping when it is stationary or moving, making the overall structure more stable.
[0039] Working principle: when it is necessary to switch from the support of the wheel body 1 to the support of the support seat 3, first disengage the sliding rod 23 from the socket 22, and rotate the first rotating rod 5 90 degrees counterclockwise. At this time, the support seat 3 will replace the wheel body 1 support. Since the pawl 8 is stuck in the teeth of the ratchet 6 under the action of the limit spring 9, the sliding rod 23 is inserted into the corresponding socket 22 for further fixation, thereby achieving the fixation of the support seat 3. When it is necessary to switch from the support of the support seat 3 back to the support of the wheel body 1, first disengage the sliding rod 23 from the socket 22, rotate the handle 10 in the opposite direction, drive the pawl 8 to disengage from the ratchet 6, so that the ratchet 6 and the first rotating rod 5 can rotate in the opposite direction, and then insert the sliding rod 23 into the corresponding socket 22 for further fixation, thereby retracting the support seat 3 and restoring the support state of the wheel body 1.
[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
