[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0021] Reference Figure 1-3 As shown, a counter for a falling ball impact tester includes a tester body 1 and a counter body 2 mounted on the tester body 1, and a plurality of buttons 3 are provided on the counter body 2;

[0022] The setting of the counter body 2 can facilitate the accurate recording of the number of falling impacts of the wear-resistant balls when the wear-resistant ball impact test is performed on the testing machine body 1, thereby assisting in recording the test data.

[0023] In addition, the counter body 2 is an existing conventional test counting instrument, and its internal structure and counting principle are technical features that are already well known to the public, so this case will not introduce them in detail.

[0024] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that the outside of the counter body 2 is equipped with an inverted U-shaped protective frame 4. The side of the protective frame 4 away from the counter body 2 is provided with a plurality of mounting holes corresponding to the buttons 3. The mounting holes are equipped with elastic pressing members. The top of the protective frame 4 is provided with a locking member that cooperates with the elastic pressing member.

[0025] The elastic pressing member can prevent the human finger from directly pressing the key 3 without affecting the pressing operation of the key 3, thereby preventing sweat and dirt from the hand from directly contaminating the surface of the key 3 and affecting the use of the key 3 to a certain extent.

[0026] By setting up the locking piece and the protective frame 4, when the counter body 2 is idle, the locking piece is used to strengthen the elastic pressing piece. The elastic pressing piece and the protective frame 4 cooperate to effectively build a solid protective barrier above the button 3 to prevent the button 3 from being affected by accidental human touch and affecting the use effect of the counter body 2.

[0027] Specifically, refer to Figure 2 As shown, it is worth noting that the elastic pressing member includes an extrusion column 5 vertically slidably arranged in the mounting hole and a pressing ring 6 tightly sleeved on the outer wall of the top of the extrusion column 5. A compression spring 7 is sleeved on the outer wall of the extrusion column 5 located between the pressing ring 6 and the top surface of the protective frame 4;

[0028] By pressing the pressing ring 6, the pressing ring 6 is squeezed and can move down in the mounting hole and contact the button 3, thereby forming a squeezing effect on the button 3. During this process, the pressing ring 6 can still continue to compress the compression spring 7 to deform, and then when the button 3 is pressed and the pressing ring 6 is no longer pressed, the pressing ring 6 can carry the squeezing column 5 to quickly reset under the elastic force of the compression spring 7, which is convenient for secondary use.

[0029] Further, refer to Figure 2 As shown, it is worth noting that an anti-slip ring 8 is fixedly sleeved on the outer wall of the bottom of the extrusion column 5 and fits with the inner wall of the protection frame 4;

[0030] The provision of the anti-slip ring 8 can prevent the extrusion column 5 from being excessively elastically forced by the compression spring 7 and detaching from the installation groove when manually releasing the pressure on the pressing ring 6, thereby affecting the use effect.

[0031] Further, refer to Figure 1 and Figure 3 As shown, it is worth noting that the locking member includes a movable plate 9 slidably arranged above the protective frame 4 and a plurality of plug posts 10 equidistantly fixed to the bottom surface of the movable plate 9. The outer wall of the extrusion column 5 is provided with a positioning hole 11 adapted to the plug posts 10. The end of the plug post 10 penetrates into the mounting hole and extends into the positioning hole 11.

[0032] When the counter body 2 is idle, lower the movable plate 9 so that the insertion column 10 is inserted into the positioning hole 11. This can lock the extrusion column 5 to ensure the stability of the extrusion column 5 in the mounting hole. Even if the extrusion column 5 is accidentally touched and squeezed, the extrusion column 5 can still be firmly placed in the mounting hole.

[0033] Further, refer to Figure 1 As shown, it is worth noting that both ends of the movable plate 9 are penetrated by guide columns 12 fixedly connected to the top surface of the protection frame 4;

[0034] Through the setting of the guide column 12, when the movable plate 9 slides down, the movable plate 9 can slide synchronously along the rod body of the guide column 12, which can effectively limit the moving trajectory of the movable plate 9 and the plug column 10, ensuring the stability of the movable plate 9 during movement.

[0035] Further, refer to Figure 2 As shown, it is worth noting that both ends of the protection frame 4 are provided with sockets 13 fixedly connected to the outer wall of the counter body 2;

[0036] By providing the inserting sleeve 13 , the end of the protection frame 4 is inserted into the inner side of the inserting sleeve 13 , so that the protection frame 4 can be easily assembled on the outside of the counter body 2 .

[0037] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
