Description
Technical Field
[0001] The present application relates to the technical field of wheels, and in particular to a wheeled mobile vehicle. Background Art
[0002] Tires are a type of wheel. They are donut-shaped elastic rubber products installed on various vehicles or machinery. Their main functions are to support the vehicle body, cushion external impacts, and achieve contact with the road surface, thereby ensuring the vehicle's driving performance.
[0003] Tires are generally moved and transported using wheeled dollies. Existing wheeled dollies have a relatively simple structure and only serve to support the tires. When encountering bumps during movement, the tires are prone to tipping over or falling off, resulting in low stability, which affects the normal transportation of the tires. In addition, tires are generally heavy, and when they fall off, they are easy to injure the instep, posing certain safety hazards. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the present application provides a wheeled mobile vehicle that can position the carried tires and cushion and reduce shock for the tires, thereby improving the stability of the tires during movement, preventing the tires from tipping over and falling off from the mobile vehicle when encountering bumps, ensuring the normal transportation of the tires, and improving the safety of tire transportation. It solves the problem that the existing wheeled mobile vehicles are relatively simple and only have the function of supporting the tires. When encountering bumps during movement, the tires are prone to tipping over or falling off, and the stability is low, affecting the normal transportation of the tires. In addition, tires are generally heavy, and after falling off, they are easy to injure the instep, posing certain safety hazards.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a wheeled mobile vehicle, comprising a frame, a placement rack is provided inside the frame, and placement slots are arranged at equal intervals inside the placement rack. A screw rod is rotatably connected to the inside of the frame, and the bottom of the screw rod is rotatably connected to the inside of the placement rack. The outer circumference of the screw rod is threadedly connected to a threaded tube, and the outer circumference of the threaded tube is fixedly connected to two limit racks. A bottom plate is provided at the bottom of the frame, and four dampers are fixedly connected to the upper surface of the bottom plate, and the top of each damper is fixedly connected to the bottom surface of the frame. Four springs are fixedly connected to the upper surface of the bottom plate, and two rings are fixedly connected to both sides of the frame, and the tops of the springs are respectively fixedly connected to the bottom surfaces of the rings.
[0006] Through the above scheme, since the existing wheeled mobile vehicle is relatively simple and only has the function of supporting the tire, when encountering bumps during movement, the tire is easy to tip over or fall off, and the stability is low, which affects the normal transportation of the tire. In addition, the tire is generally heavy, and it is easy to injure the instep after the tire falls off, which poses a certain safety hazard. By rotating the screw rod to drive the threaded tube downward, the limit frame is prompted to press the tire in the placement groove, position the tire, and prevent the tire from tipping over and falling off from the mobile vehicle when encountering bumps, thereby ensuring the normal transportation of the tire and improving the safety of tire transportation. By setting a damper and a spring, the moving tire is buffered and shock-absorbing, further improving the stability of tire transportation.
[0007] Furthermore, four columns are fixedly connected to the upper surface of the base plate, and the inner walls of the collars are slidably sleeved with the outer circumferential surfaces of the columns respectively.
[0008] Through the above solution, the frame is restricted, so that the frame is always lifted and lowered longitudinally, thereby improving the stability of the frame during transportation.
[0009] Furthermore, the placement grooves are arranged in an arc shape, and a buffer pad is provided at the bottom of each placement groove.
[0010] Through the above solution, the arc-shaped placement groove can adapt to the contour of the tire, improving the stability of the tire inside the placement groove, and the buffer pad at the bottom of the placement groove can cushion the tire, further improving the stability of the tire during transportation.
[0011] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the screw rod, and the outer circumferential surface of the limiting ring is rotatably connected to the interior of the frame.
[0012] Through the above solution, the screw rod is restricted to avoid longitudinal sliding of the screw rod and improve the stability of the screw rod movement.
[0013] Furthermore, two handles are fixedly connected to both sides of the frame, and the outer surface of each handle is covered with a soft cover.
[0014] Through the above solution, the mobile cart can be pushed to move by the handle, and the soft cover on the handle can improve the comfort of the hand.
[0015] Furthermore, a limiting rod is fixedly connected to the interior of the frame, and one end of the limiting frame away from the threaded tube is slidably sleeved with the outer circumferential surface of the limiting rod.
[0016] Through the above solution, the limit frame is restricted, so that the limit frame is always lifted and lowered longitudinally, the threaded tube is prevented from rotating with the lead screw, and the stability of the limit frame movement is improved.
[0017] Furthermore, rollers are provided at the four corners of the base plate.
[0018] Through the above solution, the rollers can support the mobile vehicle and facilitate the movement of the mobile vehicle.
[0019] Furthermore, a handwheel is provided at the top end of the screw rod, and an outer circumferential surface of the handwheel is provided with anti-slip grooves arranged at equal intervals.
[0020] Through the above solution, the screw rod can be controlled by the handwheel, thereby controlling the lifting and lowering of the threaded tube and the limit frame, providing convenience for the user.
[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0022] The wheeled mobile cart drives the threaded tube to move downward by rotating the screw rod, prompting the limit frame to press the tire in the placement groove, thereby positioning the tire, preventing the tire from tipping over and falling off from the mobile cart when encountering bumps, ensuring normal transportation of the tire, and improving the safety of tire transportation. The mobile cart is provided with a damper and a spring to buffer and reduce shock, further improving the stability of tire transportation, and solving the problem that the existing wheeled mobile cart has a relatively simple structure, the tires on the mobile cart are easy to tip over and fall off during transportation, and have low stability and safety.

Two rings 18 are fixedly connected to both sides of the frame 1, and the tops of the springs 4 are respectively fixedly connected to the bottom surfaces of the rings 18.
[0031] See also Figure 1 and Figure 3 Four columns 5 are fixedly connected to the upper surface of the base plate 17, and the inner walls of the collars 18 are respectively slidably connected to the outer circumferential surfaces of the columns 5 to restrict the frame 1, so that the frame 1 is always lifted longitudinally, thereby improving the stability of the frame 1 during transportation.
[0032] See also Figure 1 and Figure 2 The placement groove 6 is arranged in an arc shape, and a buffer pad 10 is provided at the bottom of each placement groove 6. The arc-shaped placement groove 6 can adapt to the contour of the tire, thereby improving the stability of the tire inside the placement groove 6. The buffer pad 10 at the bottom of the placement groove 6 can cushion the tire, further improving the stability of the tire during transportation.
[0033] See also Figure 3 The outer circumference of the screw rod 7 is fixedly sleeved with a limit ring 11, and the outer circumference of the limit ring 11 is rotatably connected to the inner part of the frame 1 to limit the screw rod 7, prevent the screw rod 7 from sliding longitudinally, and improve the stability of the screw rod 7 movement.
[0034] See also Figure 1 and Figure 3 Two handles 12 are fixedly connected to both sides of the frame 1. The outer surface of each handle 12 is covered with a soft cover 13. The handle 12 can be used to push the mobile vehicle to move. The soft cover 13 on the handle 12 can improve the comfort of the hand.
[0035] See also Figure 1 and Figure 3The frame 1 is fixedly connected to the limit rod 14 inside, and the end of the limit frame 9 away from the threaded tube 8 is slidably connected to the outer circumferential surface of the limit rod 14, which limits the limit frame 9 and prompts the limit frame 9 to always move up and down longitudinally, preventing the threaded tube 8 from rotating with the screw rod 7, thereby improving the stability of the movement of the limit frame 9.
[0036] See also Figure 1 and Figure 3 Rollers 15 are provided at the four corners of the bottom plate 17. The rollers 15 can support the mobile vehicle and facilitate the movement of the mobile vehicle.
[0037] See also Figure 1 and Figure 3 A handwheel 16 is provided at the top of the screw rod 7, and the outer circumferential surface of the handwheel 16 is provided with anti-slip grooves arranged at equal intervals. The screw rod 7 can be controlled by the handwheel 16, thereby controlling the lifting and lowering of the threaded tube 8 and the limit frame 9, providing convenience for the user.
[0038] A wheeled mobile vehicle in this embodiment drives the threaded tube 8 to move downward by rotating the screw rod 7, prompting the limit frame 9 to press the tire in the placement groove 6, positioning the tire, preventing the tire from tipping over and falling off from the mobile vehicle when encountering bumps, ensuring normal transportation of the tire, and improving the safety of tire transportation. By providing a damper 3 and a spring 4, the mobile vehicle is buffered and shock-absorbing, further improving the stability of tire transportation, solving the problem that the structure of the existing wheeled mobile vehicle is relatively simple, the tires on the mobile vehicle are easy to tip over and fall off during transportation, and the stability and safety are low.
[0039] It should be noted that the springs 4 are respectively sleeved on the outside of the pillars 5 , and the dampers 3 , springs 4 and pillars 5 are respectively arranged at the four corners of the bottom plate 17 to provide uniform and stable support for the frame 1 .
[0040] The working principle of the above embodiment is:
[0041] When the tire needs to be loaded and transported, the tire is placed in the placement groove 6 opened inside the placement rack 2. The arc-shaped placement groove 6 can play a certain limiting role on the tire, thereby improving the stability of the tire. After the tire is placed in the placement groove 6 in turn, the screw rod 7 is rotated by the hand wheel 16 to drive the threaded tube 8 to move down, and the threaded tube 8 drives the limiting rack 9 to move down. After the limiting rack 9 moves down to the bottom, it will contact the top of the tire in the placement groove 6, pressing the tire tightly in the placement groove 6, positioning the tire, and preventing the tire in the placement groove 6 from falling off when the mobile vehicle encounters bumps during movement, thereby improving the stability of the tire during transportation. When the vehicle moves, the gravity of the frame 1, the placement rack 2 and the tire on the placement rack 2 will act on the damper 3 and the spring 4. When the mobile vehicle encounters bumps during movement, the impact generated by the bumps will act on the damper 3 and the spring 4. The damper 3 and the spring 4 cushion the impact on the mobile vehicle, further improving the stability of the mobile vehicle and tire transportation. The column 5 and the ring 18 can limit the frame 1, prompting the frame 1 to always move up and down longitudinally. When the tire needs to be removed from the placement groove 6, the screw rod 7 is rotated in the opposite direction to drive the limit frame 9 to move up through the threaded tube 8, thereby canceling the positioning restriction of the tire and removing the tire.
