Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] This utility model provides, for example Figure 1-3 The image shows a fixing device for abrasion resistance testing of flocked rollers in vacuum cleaners.
[0038] Example 1
[0039] The test unit includes a test body 1; a test table 2 is located inside the test body 1, and the material of the test table 2 can be selected according to requirements. Flocked rollers roll back and forth on the test table 2 to conduct abrasion resistance tests. A slide table 3 is provided on the top of the test table 2; a positioning mechanism 4 is located on the side of the test table 2. The positioning mechanism 4 is used to lock the installation position of the test table 2 for installation and replacement.
[0040] Furthermore, the positioning mechanism 4 includes a support frame 41, a movable plate 42, and a connecting plate 44. The support frame 41 provides support for the test bench 2, allowing the movable plate 42 to slide within it. The movable plate 42 facilitates the movement of the locking pin 43, enabling the locking pin 43 to connect or disconnect from the inner cavity of the limiting groove. The connecting plate 44 simultaneously pushes two movable plates 42 in the same row to slide horizontally, allowing the test bench 2 to be directly released from position constraints and replaced directly, facilitating operation. The support frame 41 is fixedly connected to the side of the test bench 2, and the movable plate 42 is slidably inserted into the inner cavity of the support frame 41. The locking pin 43 is fixedly connected to the side of the movable plate 42, which helps to limit the relative position of the movable plate 42 and the test bench 2, facilitating the installation and disassembly of the test bench 2. The support frame 41 is connected to the test body 1 through the movable plate 42 and the locking pin 43, and the connecting plate 44 is fixedly connected to the top of the adjacent movable plate 42.
[0041] Furthermore, the positioning mechanism 4 also includes an installation groove, a limiting groove, a positioning post 45, an elastic element, and a limiting element. The positioning post 45 is beneficial for positioning the test bench 2 during installation and prevents the test bench 2 from slipping or sliding randomly. The installation groove is located on the top of the test body 1, and the moving plate 42 is slidably inserted into the inner cavity of the installation groove. The limiting groove is located on the side of the inner wall of the installation groove, and the locking post 43 is slidably inserted into the inner cavity of the limiting groove. The positioning post 45 is fixedly connected to the top of the test body 1. The bottom of the test bench 2 is provided with a positioning groove that matches the positioning post 45. The elastic element is located inside the support frame 41, and the limiting element is located on the side of the support frame 41. The limiting element is used to install and fix the elastic element.
[0042] Specifically, the elastic components include an assembly plate 46, a second rod 48, and a spring 49. The assembly plate 46 supports the first rod 47 and the second rod 48, facilitating traction operations on the first rod 47 and the second rod 48. The spring force of the spring 49 helps to move the moving plate 42, allowing the moving plate 42 and the locking pin 43 to return to their original positions after movement, facilitating repeated operations on the locking pin 43. The first rod 47 is fixedly connected to the side of the assembly plate 46. The first rod 47 is slidably inserted into the side of the support frame 41. The outer wall of the first rod 47 is slidably inserted into the movable plate 42. The second rod 48 is fixedly connected to the side of the assembly plate 46. The second rod 48 is inserted through the support frame 41. The outer wall of the second rod 48 is slidably inserted into the movable plate 42. The spring 49 is sleeved on the outside of the first rod 47 and the second rod 48. One end of the spring 49 is in contact with the movable plate 42, and the other end of the spring 49 is in contact with the inner wall of the support frame 41.
[0043] Example 2
[0044] Based on Embodiment 1, the limiting component includes a support base 410, a mounting base 411, a first magnet 413, and a second magnet 414. The support base 410 facilitates vertical guidance and support for the sliding of the limiting post 412. The mounting base 411 facilitates connection with the limiting post 412, thereby facilitating the installation and disassembly of the second rod 48, and the installation and disassembly of the moving plate 42 and the spring 49. The first magnet 413 and the second magnet 414 help limit the position of the limiting post 412, preventing it from sliding arbitrarily. The support base 410 is fixedly connected to the other side of the support frame 41. The inner cavity of the support base 410 slides... A limiting post 412 is slidably inserted into the second rod 48. A mounting base 411 is fixedly connected to the other side of the support frame 41. The limiting post 412 is slidably inserted into the inner cavity of the mounting base 411. A first magnet 413 is fixedly connected to the end of the limiting post 412. A second magnet 414 is fixedly connected to the inside of the mounting base 411. The opposite magnetic poles of the second magnet 414 and the first magnet 413 are opposite. The first magnet 413 and the second magnet 414 magnetically attract each other to limit the installation position of the limiting post 412, preventing the limiting post 412 from sliding up and down arbitrarily and improving the stability of use.
