Description

Technical Field

[0001] This application relates to the technical field of wear resistance testing equipment, specifically a wear resistance testing device for plastic handles. Background Technology

[0002] Plastic handles are lifting accessories made primarily of synthetic resins such as polypropylene (PP) and polyethylene (PE), with added plasticizers, stabilizers, and other auxiliary materials. They are lightweight, sturdy, and have good chemical stability. During the production process of plastic handles, it is necessary to test their wear resistance in order to assess their service life. For example, patent CN2650117Y discloses a testing device for the abrasion resistance of plastic films. This patent involves laying the film sample to be tested flat on a platform, or covering the film sample with a pressure block, and then activating a reciprocating motion mechanism. The pressure block rubs against the film, or the pressure block drives the film to rub against the platform. By determining the pressure of the pressure plate on the platform, the speed of the reciprocating motion, and the time, an objective and stable evaluation standard can be established. This also eliminates the hassle of manual testing and the errors caused by human influence. While the aforementioned patents can test the wear resistance of plastic parts, there are many types and sizes of plastic handles. Therefore, different friction strokes are required for different sizes of plastic handles in order to obtain complete test data. However, the aforementioned devices can only perform single-stroke tests, which has poor applicability. Therefore, it is necessary to provide a plastic handle wear resistance testing device to solve the above problems.

[0003] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0016] like Figures 1-3 As shown, this application provides a plastic handle wear resistance testing device, including a base 1, a left side plate 2 fixedly installed on the upper end of the base 1, a motor 3 fixedly installed on the upper end of the left side plate 2, and a disc 4 fixedly installed on the output end of the motor 3, so that the disc 4 is adapted to rotate with the operation of the motor 3. Meanwhile, a right side plate 7 is fixedly installed on the upper end of the base 1. A horizontal slide rail 8 is fixedly installed on the right side plate 7. A slide table 9 is slidably arranged on the slide rail 8, so that the slide table 9 can slide horizontally on the slide rail 8. Furthermore, a connecting rod 5 is eccentrically hinged to the disk 4, and the other end of the connecting rod 5 is hinged to the slide table 9. Thus, when the disk 4 rotates, the connecting rod 5 can drive the slide table 9 to reciprocate in the horizontal direction. Continue to refer to Figures 1-3 A fixed base 15 is fixedly installed on the upper end of the right side plate 7. A lead screw 12 is threaded onto the fixed base 15. A slide groove 91 is vertically provided on the slide table 9. A slide block 11 is slidably arranged inside the slide groove 91. The slide block 11 is connected to the lead screw 12 for transmission. So when the lead screw 12 rotates, it can drive the slide block 11 to move vertically within the slide groove 91. Furthermore, a connecting seat 13 is fixedly installed at the lower end of the slide 11, and a friction block 14 is detachably installed at the lower end of the connecting seat 13. Thus, the friction block 14 can adjust its height position under the drive of the slide 11 and move horizontally synchronously with the slide table 9. It should be noted that a friction table 6 is installed on the upper end of the base 1. The friction table 6 is used to place the plastic handle to be polished, and a clamping component (not shown in the figure) is provided on the friction table 6. The clamping component is used to fix the plastic handle to facilitate subsequent wear resistance testing. In summary, when it is necessary to test the abrasion resistance of a plastic handle, the plastic handle is first fixed on the friction table 6 by the clamping assembly. Then, the height of the friction block 14 is adjusted so that the friction block 14 is pressed against the surface of the plastic handle. Finally, the horizontal movement of the friction block 14 is driven by the slide table 9 so that the friction block 14 repeatedly contacts and rubs against the plastic handle, thereby completing the abrasion resistance test of the plastic handle. Furthermore, a handwheel 10 is fixedly installed at the upper end of the lead screw 12 to facilitate the operator to rotate the lead screw 12 and thereby adjust the height position of the friction block 14.

[0017] To change the friction stroke of friction block 14 to accommodate plastic handles of different sizes, such as... Figure 2 As shown, multiple sets of adjustment holes 41 are provided on the disc 4. The multiple sets of adjustment holes 41 are arranged sequentially along a position away from the center of the disc 4. At the same time, the connecting rod 5 has a first locking member 52 that is installed with the adjustment hole 41. Thus, when the connecting rod 5 is installed with different adjustment holes 41, the rotation trajectory of the connecting rod 5 can be changed, thereby adjusting the distance of the horizontal reciprocating motion of the friction block 14 to adjust the friction stroke of the friction block 14.

[0018] like Figure 2 and Figure 4As shown, the connecting rod 5 also includes a fixing rod 51, which has a first round head 53, and the first round head 53 is rotatably mounted to the first locking member 52; Meanwhile, a second locking member 55 is installed on the slide table 9, and the connecting rod 5 also includes a movable rod 515, which has a second round head 54, which is rotatably mounted on the second locking member 55; Furthermore, the fixed rod 51 and the movable rod 515 are adapted to move closer or further apart to change the length of the connecting rod 5, thereby changing the initial position of the friction block 14, so as to test the wear resistance of the plastic handle at different clamping positions. To connect the fixed rod 51 and the movable rod 515, such as Figure 2 and Figure 4 As shown, a sleeve 56 is fixedly installed at the end of the movable rod 515 away from the second round head 54. The sleeve 56 has a second internal thread 514 inside. At the same time, a first screw 57 is installed in the internal thread of the second internal thread 514. An extension post 59 is provided at one end of the first screw 57. The extension post 59 has a first internal thread 510 inside. Meanwhile, a rotating groove 513 is provided on the fixed rod 51, and a locking pin 511 is rotatably provided in the rotating groove 513. The thickness of the locking pin 511 is adapted to the width of the rotating groove 513. A second screw 512 is provided on the locking pin 511, and the second screw 512 is installed in conjunction with the second internal thread 514. Thus, the first screw 57 not only connects the fixed rod 51 and the movable rod 515, but also allows the first screw 57 to be rotated as needed to adjust the distance between the fixed rod 51 and the movable rod 515. At this time, because the thickness of the locking pin 511 is adapted to the width of the rotating groove 513, the relative position between the fixed rod 51 and the movable rod 515 remains unchanged along the length direction of the connecting rod 5, so the positions of the fixed rod 51 and the movable rod 515 are relatively fixed. Furthermore, a square body 58 is provided on the extension column 59 to facilitate the operation of the first screw 57 by the staff.

[0019] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
