Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The existing testing machine is not convenient for adjusting the measuring position of the impact head, which prolongs the operation time and reduces the working efficiency in the continuous test.

[0021] In view of this, a coating impact testing machine is provided, which realizes the adjustment and positioning of the measuring height through the cooperation between the scale, the slider and the screw. When measurement is needed, the arc rod can be rotated, which solves the problem that the existing testing machine is not convenient for adjusting the measuring position of the impact head, prolongs the operation time in continuous tests, and reduces work efficiency.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: Figure 1-2 It can be seen that a coating film impact tester includes a base plate 1, a bracket 11 is installed on the top of the base plate 1, a cylinder 13 is installed in the front groove of the bracket 11, a scale 12 is processed on the front of the cylinder 13, and an auxiliary mechanism is arranged on the front of the cylinder 13. The auxiliary mechanism includes a slider 14, a block 20, a measuring head 21, a convex block 19, a screw 15, an arc rod 18 and a straight rod 16. The outer walls of the slider 14 and the block 20 are slidably engaged with the front groove of the cylinder 13, and a convex block 19 is arranged inside the slider 14. The slider 14 is limited to vertical movement, and the slider 14 and the block 20 can move in the front groove of the cylinder 13. The inner side of the slider 14 is tightly pressed against the inner side of the front groove of the cylinder 13 by the screw 15. The front side of the slider 14 is rotatably connected to a straight rod 16 through a pin shaft. The straight rod 16 can rotate through the pin shaft. One end of the straight rod 16 is fixedly connected to an arc rod 18. The outer side of the arc rod 18 is movably connected to a convex block 19 fixed to the front side of the block 20. The slider 14 fits the inner side of the block 20.

[0024] In the specific implementation process, it is worth pointing out that the adjustment and positioning of the measuring height are realized through the cooperation between the screw 15, the arc rod 18 and the straight rod 16. When measurement is required, the arc rod 18 can be rotated, which solves the problem that the existing testing machine is not convenient for adjusting the measuring position of the impact head, prolongs the operation time in continuous testing, and reduces the work efficiency.

[0025] Furthermore, a spring 17 is provided on the front pin of the straight rod 16, and the two ends of the spring 17 are fixedly connected to the front of the straight rod 16 and the front of the slider 14 respectively;

[0026] In the specific implementation process, it is worth pointing out that the device relies on the elastic deformation of the spring 17 to drive the arc rod 18 to be inserted into the groove of the protrusion 19 for fixation;

[0027] Specifically, when using the coating impact testing machine, the user can insert the arc rod 18 into the groove of the protrusion 19 for positioning, then pull the slider 14 to the appropriate position, turn the screw 15 to tighten and fix it, and rotate the arc rod 18 when measurement is required. The position of the scale at the top of the slider 14 represents the position of the bottom of the measuring head 21.

[0028] Embodiment 2: By Figure 1-4 It can be seen that a straight plate 22 is fixedly connected to the lower inner side of the bracket 11, and the inner side of the straight plate 22 is fixedly connected to the top of the bottom plate 1 by bolts;

[0029] In the specific implementation process, it is worth pointing out that a plurality of thread grooves are provided on the top of the base plate 1, and the position of the measuring head 21 can be changed as needed;

[0030] Further, a pad 2 is fixedly connected to the top of the bottom plate 1, a back plate 3 and a square plate 7 are installed on the top of the bottom plate 1, a through hole of the square plate 7 is movably connected to a limit rod 9, the limit rod 9 can move laterally in the through hole of the square plate 7, one end of the limit rod 9 is fixedly connected to a pressing plate 5, and a first rubber plate 4 and a second rubber plate 6 are installed on the inner sides of the pressing plate 5 and the back plate 3 respectively, and the container is placed in the middle position of the pressing plate 5 and the back plate 3 for fixing;

[0031] In the specific implementation process, it is worth pointing out that the first rubber sheet 4 and the second rubber sheet 6 rely on their own elastic deformation to contact with the container, thereby increasing the friction force and ensuring stability;

[0032] Furthermore, the inner side of the square plate 7 is rotatably connected to a screw rod 8 through a bearing, the screw rod 8 can rotate through the bearing, the outer side of the screw rod 8 is threadedly connected to a sleeve 10, and the top of the sleeve 10 is fixedly connected to the bottom of the limit rod 9;

[0033] In the specific implementation process, it is worth pointing out that when the screw 8 rotates, it can drive the sleeve 10 to move horizontally, and when the sleeve 10 moves, it can drive the limit rod 9 and the pressure plate 5 to move horizontally, so as to fix the container;

[0034] Specifically, on the basis of the above-mentioned embodiment 1, the round canned container is fixed by the cooperation among the square plate 7, the screw rod 8 and the limiting rod 9, thereby avoiding random movement during impact and ensuring the accuracy of the result.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0036] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
