Abstract
Description
Technical Field
[0001] This utility model relates to the field of universal wheel production and processing technology, and in particular to a wire-plated universal wheel. Background Technology
[0002] A multi-wheel is a tool used to measure linear dimensions such as length and distance. It mainly consists of a graduated roller and a counting device such as a pointer or dial. During measurement, the roller is rolled along the surface of the object being measured. The circumference of the roller is known. By recording the number of rotations or partial rotations of the roller and combining this with the reading on the dial, the length or distance of the object can be calculated.
[0003] Traditional wire-plated universal wheels are typically manufactured using simple processes and are usually made of common metals, resulting in low production costs and ease of mass production. However, traditional wire-plated universal wheels lack a buffer structure between the wheel and the base. This means that when the wheel and base are subjected to collisions or vibrations, the internal mechanical components experience a hard impact. Over time, this impact can loosen the connection between the wheel and the base, affecting the accuracy of the final test results. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a wire plating universal wheel, which aims to improve the problem that the traditional wire plating universal wheel does not have a buffer structure between it and the base, which causes the connection structure between the universal wheel and the base to loosen due to long-term impact, thus affecting the accuracy of the final test results.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A wire plating universal wheel includes a universal wheel body, a collar rotatably connected to the outer wall of the universal wheel body, a fixed post fixedly connected to the inner wall of the collar, a transmission arm fixedly connected to the outer wall of the fixed post, a stop block fixedly connected to the outer wall of the fixed post, a slider rotatably connected to the inner wall of the transmission arm, a second spring provided on the outer wall of the slider, a base slidably connected to the outer wall of the slider, and a reset assembly provided on the outer wall of the slider for resetting the slider.
[0007] Preferably, the reset assembly includes a sliding post, the outer wall of which is fixedly connected to the outer wall of the slider, and a first spring is provided on the outer wall of the sliding post.
[0008] Preferably, the outer wall of the first spring is provided with a support column.
[0009] Preferably, the outer wall of the universal wheel body is provided with a shell, the inner wall of the shell is provided with a threaded hole, the inner wall of the shell is threadedly connected with a threaded rod, the threaded rod is threadedly connected to the inner wall of the shell through the threaded hole, the outer wall of the threaded rod is fixedly connected with a stop cap, and the outer wall of the threaded rod is threadedly connected with a threaded cap.
[0010] Preferably, the outer wall of the stop cap is disposed on the outer wall of the outer shell, and the outer wall of the threaded cap is disposed on the outer wall of the outer shell.
[0011] Preferably, the outer wall of the sliding column is slidably connected to the inner wall of the support column.
[0012] Preferably, the inner wall of the base is provided with a sliding groove, and the outer wall of the slider is slidably connected to the inner wall of the base through the sliding groove.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, when the universal wheel body is subjected to an external force, it will first drive the collar to move, and then drive the fixed column to move. When the fixed column moves, it will drive the transmission arm to rotate, and the rotation of the transmission arm will drive the slider to slide. When the slider slides, it will stretch the second spring and cooperate with the sliding column to compress the first spring. Thus, the sliding of the slider will buffer the universal wheel body to a certain extent, preventing the connection structure between the universal wheel and the base from loosening due to long-term impact, which would affect the accuracy of the final test results.
[0015] 2. In this utility model, when the universal wheel body is not needed, the outer shell is first placed on the outer wall of the universal wheel body, and then the threaded rod is used to fix the outer shell through the threaded hole. The threaded cap will reinforce the connection between the threaded rod and the outer shell, thereby preventing the universal wheel body from being corroded by the outside air, which would reduce the service life of the universal wheel body.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1-3 An embodiment of this utility model provides: a wire plating universal wheel, including a universal wheel body 1, a collar 2 rotatably connected to the outer wall of the universal wheel body 1, a fixing post 3 fixedly connected to the inner wall of the collar 2, a transmission arm 4 fixedly connected to the outer wall of the fixing post 3, a stop block 5 fixedly connected to the outer wall of the fixing post 3, a slider 6 rotatably connected to the inner wall of the transmission arm 4, a second spring 12 provided on the outer wall of the slider 6, a base 10 slidably connected to the outer wall of the slider 6, and a reset component provided on the outer wall of the slider 6 for resetting the slider 6;
[0024] Specifically, when the universal wheel body 1 shakes during operation, it will cause the collar 2 to move. Through the fixing action of the collar 2 and the fixed post 3, the fixed post 3 will move. The movement of the fixed post 3 is used to drive the transmission arm 4 to rotate. The rotation of the transmission arm 4 is used to drive the slider 6 to slide on the inner wall of the base 10 through the slide groove 11. The sliding of the slider 6 is used to stretch the second spring 12, thereby achieving a certain buffering and protection effect for the universal wheel body 1 when it shakes.
[0025] Reference Figure 1 , Figure 2 and Figure 3 The reset assembly includes a sliding column 7, the outer wall of which is fixedly connected to the outer wall of the slider 6, and a first spring 8 is provided on the outer wall of the sliding column 7; a support column 9 is provided on the outer wall of the first spring 8; the outer wall of the universal wheel body 1 is provided with a housing 13, the inner wall of the housing 13 is provided with a threaded hole 14, the inner wall of the housing 13 is threadedly connected with a threaded rod 15, the threaded rod 15 is threadedly connected to the inner wall of the housing 13 through the threaded hole 14, a stop cap 16 is fixedly connected to the outer wall of the threaded rod 15, and a threaded cap 17 is threadedly connected to the outer wall of the threaded rod 15;
[0026] Specifically, the first spring 8 is used to eject the sliding post 7. Through the fixing action of the sliding post 7 and the slider 6, the slider 6 is reset. When the universal wheel body 1 is not needed, the outer shell 13 is placed on the outer wall of the universal wheel body 1. The threaded rod 15 is fixed to the inner wall of the outer shell 13 through the threaded hole 14. The threaded cap 17 is used to reinforce the threaded rod 15 and the outer shell 13. Thus, when the universal wheel body 1 is not needed, the outer shell 13 protects the universal wheel body 1 and prevents it from being corroded by the outside air.
[0027] Reference Figure 1 , Figure 3 and Figure 4 The outer wall of the stop cap 16 is set on the outer wall of the outer shell 13, and the outer wall of the threaded cap 17 is set on the outer wall of the outer shell 13; the outer wall of the sliding column 7 is slidably connected to the inner wall of the support column 9; the inner wall of the base 10 is provided with a groove 11, and the outer wall of the slider 6 is slidably connected to the inner wall of the base 10 through the groove 11.
[0028] Specifically, the groove 11 is used to limit the running trajectory of the slider 6, and the support column 9 is used to support the sliding column 7.
[0029] Working principle: When the wire-plated universal wheel shakes during operation, it drives the collar 2 to move. The movement of the collar 2 moves the fixed post 3, which in turn drives the transmission arm 4 to rotate. The rotation of the transmission arm 4 causes the slider 6 to slide along the inner wall of the base 10 via the groove 11. As the slider 6 slides, it stretches or compresses the second spring 12. Simultaneously, the slider 6 causes the sliding post 7 to slide along the inner wall of the support post 9, compressing the first spring 8. This achieves the effect of buffering and protecting the universal wheel body 1 when it shakes. When it is not needed... When using the universal wheel body 1, the outer shell 13 is fitted onto the outer wall of the universal wheel body 1, and the threaded rod 15 is fixed to the inner wall of the outer shell 13 through the threaded hole 14 opened in the inner wall of the outer shell 13. Then, the threaded rod 15 and the outer shell 13 are reinforced by the threaded cap 17, thereby achieving the effect of protecting the universal wheel body 1 through the outer shell 13. Finally, the wire-plated universal wheel can not only provide a certain buffer for the universal wheel body 1 through the sliding of the slider 6 to prevent it from being damaged by external forces, but also prevent the universal wheel body 1 from being corroded by the outside air and reducing its service life by fixing the outer shell 13 to the outer wall of the universal wheel body 1.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
