Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane wheels, in particular to a polyurethane wheel which is convenient to disassemble and assemble. Background Technique

[0002] The polyurethane wheel is made of polyurethane, which is polymerized from isocyanate and hydroxyl compound. Due to the strong polar urethane group, it is insoluble in non-polar groups and has good oil resistance, toughness, wear resistance, aging resistance and adhesiveness. Materials adaptable to a relatively wide temperature range can be prepared with different raw materials, including elastomers, thermoplastic resins and thermosetting resins. It is not resistant to hydrolysis at high temperatures and is also not resistant to alkaline media.

[0003] After the production of the polyurethane wheel, it needs to be installed at the bottom of the component to be moved. Nowadays, the installation of the polyurethane wheel is generally completed by opening four or more threaded holes on the mounting plate and cooperating with positioning bolts. This installation method requires the installer to perform the work of screwing the positioning bolts at multiple points, with more steps and longer time required. Therefore, a polyurethane wheel which is convenient to disassemble and assemble is provided. Summary of the Invention

Specific implementation manners

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0022] As Figures 1-6 shown, a polyurethane wheel that is convenient for disassembly and assembly includes a mounting block 1. The upper surface of the mounting block 1 is welded to the bottom of the moving component. A notch 2 is inwardly opened on the side surface of the mounting block 1. A connecting block 3 is slidably connected inside the notch 2. A connection component 4 is installed inside the mounting block 1 and the connecting block 3. The center of the lower surface of the connecting block 3 is fixedly connected to the top end of a connection frame 5. The inner side of the bottom end of the connection frame 5 is rotatably connected to a polyurethane wheel 6. By vertically inserting the connecting block 3 into the notch 2 and pulling it downward, the first clamping block 403 is inserted into the first card slot 401. Then, pull down the U-shaped plate 409 to press down the leaf spring 405 and move it downward. At this time, insert the insertion plate 407, and then release the U-shaped plate 409, so that the leaf spring 405 rebounds to clamp the second clamping block 408 inside the second card slot 402, thus realizing the installation of the polyurethane wheel 6. When disassembling, first press down the U-shaped plate 409 and then pull out the insertion plate 407 to remove structures such as the connecting block 3. The structure is simple and the operation is fast, improving the efficiency of the installation and disassembly work of the polyurethane wheel 6.

[0023] As Figures 1-5As shown, in some embodiments, the connecting component 4 includes a first clamping groove 401. A plurality of first clamping grooves 401 are arrayed and opened on the lower surface of the two side walls of the mounting block 1 at the notch 2. A plurality of second clamping grooves 402 are arrayed and opened at the top of the inner surface of the mounting block 1. A plurality of first clamping blocks 403 are arrayed and fixedly connected to the lower surface of the part of the connecting block 3 located inside the side wall of the mounting block 1. The first clamping blocks 403 are clamped inside the first clamping grooves 401. A groove 404 is inwardly opened on the upper surface of the connecting block 3. A leaf spring 405 is arranged inside the groove 404. One end of the leaf spring 405 is fixedly connected to the side wall of the groove 404. The leaf spring 405 extends in an arc shape to the other side close to the groove 404. A sliding sleeve plate 406 is placed above the leaf spring 405. The sliding sleeve plate 406 is slidably connected to the groove 404. Through grooves 410 are symmetrically opened at the two side edges of the bottom of the connecting block 3 on both sides of the groove 404. One end of a U-shaped plate 409 is fixedly connected to the lower surface of the sliding sleeve plate 406. The U-shaped plate 409 is slidably connected inside the through grooves 410. The other end of the U-shaped plate 409 extends to the outside of the mounting block 1. A plug board 407 is slidably connected above the sliding sleeve plate 406 inside the notch 2. A plurality of second clamping blocks 408 are arrayed and fixedly connected to the upper surface of the plug board 407. The second clamping blocks 408 are clamped inside the second clamping grooves 402. Specifically, by pinching and pressing the outer side of the U-shaped plate 409 with fingers, the U-shaped plate 409 drives the sliding sleeve plate 406 to move downward. At the same time, the lower surface of the sliding sleeve plate 406 presses the leaf spring 405 downward. At this time, the plug board 407 can be inserted into the notch 2. Then, release the fingers pressing the U-shaped plate 409, and the leaf spring 405 drives the sliding sleeve plate 406 to rebound upward to press the plug board 407, so that the second clamping blocks 408 are clamped inside the second clamping grooves 402. Furthermore, due to the restriction of the plug board 407 at the top, the first clamping blocks 403 of the connecting block 3 cannot be completely pulled out and will not fall off from the inside of the mounting block 1. The plug board 407 is also pressed upward by the leaf spring 405, so that the second clamping blocks 408 are always clamped inside the second clamping grooves 402 and will not fall off. Thus, the assembly of the mounting block 1 and the connecting block 3 is realized.

[0024] As Figure 2 shown, in some embodiments, both ends of the notch 2 are opened to the center of the side wall of the mounting block 1. Specifically, by only opening to half of the side wall of the notch 2, a relatively large area remains at the connection of the upper and lower parts of the mounting block 1 at the notch 2, so that the mounting block 1 is not easily broken from the notch 2 during daily use.

[0025] As Figure 2 、 3, as shown in FIG. 4, in some embodiments, the side views of the first card slot 401 and the second card slot 402 are both triangles with one side perpendicular to the extending direction of the slot 2. The height of the second card slot 402 is less than the distance between the insertion plate 407 and the connecting block 3. Specifically, through the vertical slot 2, after the card block is clamped inside the card slot, it is not easy to slide outward from the inside of the card slot due to some shaking and collision. The height of the second card slot 402 being less than the distance between the insertion plate 407 and the connecting block 3 enables the U-shaped plate 409 to press down and the insertion plate 407 and the second card block 408 to be normally inserted into the remaining space of the slot 2.

[0026] As Figure 6 shown, in some embodiments, a trapezoidal block 7 is fixedly connected to the surface of the U-shaped plate 409 located outside the mounting block 1. The inclined surface of the trapezoidal block 7 is arrayed and fixedly connected with a plurality of anti-slip strips 8. Specifically, through the installed trapezoidal block 7 and anti-slip strips 8, the installer can more easily pull down the U-shaped plate 409 due to the slope design and the anti-slip design on the surface, avoiding the situation that it is difficult to operate when pulling down the U-shaped plate 409 due to the smooth surface.

[0027] As Figure 4 shown, in some embodiments, both ends of a connecting rod 9 are fixedly connected to the outer surface of the insertion plate 407. Specifically, through the installed connecting rod 9, when the insertion plate 407 is pulled out, the installer can hook or pinch the connecting rod 9 with fingers to pull out the insertion plate 407, making it more convenient to take out the insertion plate 407.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
