[0037] See attached document Figures 1 to 4 As shown, this application provides a striking structure suitable for large animal experiments, including a hammer assembly 1, a snap plate assembly 2, and a firing assembly 3.

[0038] in:

[0039] See Figures 1 to 2As shown, the hammer assembly 1 includes an ejection assembly 12, a guide assembly 13, and a hammer body 11. The ejection assembly 12 stores energy to launch the hammer body 11 along the guide assembly 13. Specifically, the guide assembly 13 includes a guide sleeve 130, and a guide channel is provided inside the guide sleeve 130 along its axis. The two ends of the guide channel are closed. The ejection assembly 12 includes an ejection guide post 120 and a first spring 121. The outer diameters of the ejection guide post 120 and the first spring 121 are the same as the inner diameter of the guide channel. The ejection guide post 120 and the first spring 121 are disposed within the guide channel, and in their natural state, the first spring 121 and the ejection guide post 120 fill the entire guide channel, that is, the sum of the lengths of the first spring 121 and the ejection guide post 120 is the same as the length of the guide channel. Meanwhile, the hammer body 11 includes a connecting shaft 110 and a hammer head 111. One end of the connecting shaft 110 is fixedly connected to the end of the ejector guide post 120 away from the first spring 121. The guide channel is located at one end of the connecting shaft 110 and has a through hole that allows only the connecting shaft 110 to pass through. The connecting shaft 110 extends outward along the axial direction of the guide sleeve 130 through the through hole and is fixedly connected to the hammer head 111 located outside the guide sleeve 130.

[0040] See above Figure 1 As shown, the guide sleeve 130 has an axially extending clearance groove 131 on its side wall, and the ejection guide post 120 has a trigger 122 perpendicular to the axial direction of the ejection guide post 120 on its side wall. The trigger 122 extends out of the clearance groove 131 from the guide sleeve 130 and engages with the buckle assembly 2. See also... Figures 1 to 3 As shown, the buckle assembly 2 includes a buckle base 21, a buckle body 22, an elastic baffle 23, and a trapezoidal drive block 25. The buckle base 21 is mounted with a first shaft via a bearing. The buckle body 22 is fixedly sleeved on the first shaft (not shown in the figure), so that the buckle body 22 and the first shaft rotate on the buckle base 21. The end of the buckle body 22 away from the first shaft is close to the trigger 122, and a buckle hole is provided on the buckle body 22. A buckle hook is provided on the trigger 122. The buckle body 22 and the trigger 122 are fastened together through the buckle hole and the buckle hook. The buckle base 21 is provided with a groove 210 extending along a direction perpendicular to the axis of the guide sleeve 130. The groove 210 is located on the side of the buckle body 22 away from the trigger 122. An elastic baffle 23 is installed in the groove 210. The elastic baffle 23 includes a baffle body 230 and a second spring 231. The baffle body 230 is slidably installed in the groove 210. The bottom of the baffle body 230 is fixedly connected to the second spring 231. The lower end of the second spring 231 is fixed to the side of the buckle base 21 through a side plate 232. In addition, right-angled folded plates 24 are integrally formed on both sides of the baffle body 230. Trapezoidal driving blocks 25 are integrally formed on the right-angled folded plates 24 on both sides. The trapezoidal driving blocks 25 protrude toward the trigger 122.

[0041] In the above, in order to enable the buckle assembly 2 to drive the ejection assembly 12 to compress the first spring 121 and store energy, such as Figure 2 As shown, the buckle assembly 2 also includes a drive assembly for moving the buckle base 21. The drive assembly includes a first guide rail 26, a guide screw 28, and a drive motor 27. The first guide rail 26 is arranged in a direction parallel to the axial direction of the guide assembly 13. The first guide rail 26 has a first side groove along its side wall. The buckle base 21 is disposed in the first guide rail 26 and protrudes along the first side groove to form a limit, so that the buckle base 21 will not fall out of the first guide rail 26. The two ends of the first guide rail 26 are integrally formed with side stops 261. The guide screw 28 is disposed along the first guide rail 26 and its two ends are connected to the side stops 261 by bearings. The buckle base 21 is threadedly connected to the guide screw 28. The drive motor 27 is connected to one end of the guide screw 28 by a coupling. As can be imagined, the movement of the drive motor 27 can drive the buckle base 21 to move along the guide screw 28. Since the buckle body 22 is engaged with the trigger 122, and the baffle body 230 blocks the buckle body 22 from rotating away from the trigger 122, the buckle base 21 moves to drive the ejection guide post 120 to compress the first spring 121 to store energy.

[0042] In this embodiment, see Figure 2 and Figure 4 As shown, the firing assembly 3 includes a second guide rail 31, a slide 32, and an L-shaped plate 33. The second guide rail 31 is fixedly arranged side-by-side on both sides of the first guide rail 26, and is parallel to the trapezoidal drive block 25. The sidewall of the second guide rail 31 has several positioning screw holes along its length. Different positioning screw holes correspond to different compression amounts of the first spring 121, and different compression amounts of the first spring 121 correspond to different striking forces and striking heights. The second guide rail 31 also has a second side groove along its sidewall. The slide 32 is slidably installed within the second guide rail 31 and protrudes into the second side groove, ensuring that the slide 32 is limited and does not fall out. A positioning bolt 36 is provided on the slide 32, allowing it to be positioned at different locations by screwing the positioning bolt 36 into the positioning screw hole. An L-shaped plate 33 is fixedly mounted on the upper surface of the slide table 32, and a trapezoidal stop 34 adapted to the trapezoidal drive block 25 is provided at the bottom of the horizontal section of the L-shaped plate 33. It can be imagined that when the trapezoidal drive block 25 contacts the trapezoidal stop 34, the baffle body 230 is first pressed down and then bounced up.

[0043] It is understandable that, in a preferred embodiment, a hexagonal countersunk hole is provided on the outer end face of the positioning bolt 36 to facilitate tightening of the positioning bolt 36 with a hexagonal wrench.

[0044] Based on the above, such as Figure 1 and Figure 2As shown in the embodiment of this application, a striking structure suitable for large animal experiments is provided, and its working principle is as follows:

[0045] First, use a hex wrench to unscrew the positioning bolt 36 outwards to separate it from the second guide rail 31 and the slide 32. According to the required striking force, move the slide 32 to the corresponding positioning screw hole. After the slide 32 moves to the designated point, screw the positioning bolt 36 into the corresponding positioning screw hole to fix the position of the slide 32. At this time, the compressible length of the first spring 121 is determined, thereby setting the striking force and striking height.

[0046] Next, the drive motor 27 is started, driving the guide screw 28 to rotate in the forward direction. The buckle base 21 then drives the buckle body 22 to move along the guide screw 28 towards the drive motor 27. Since the buckle body 22 is engaged with the trigger 122, and since the buckle body 22 is blocked by the baffle body 230 and cannot rotate away from the trigger 122, the ejector guide post 120 moves towards the first spring 121 along the guide channel under the movement of the buckle body 22, thereby compressing the first spring 121. When the buckle body 22 moves to the trapezoidal drive block 2... When the trapezoidal stop block 34 comes into contact with the trapezoidal drive block 25, the trapezoidal drive block 25 is pressed and drives the baffle body 230 to move along the slide groove 210, compressing the second spring 231 to provide space for the rotation of the buckle body 22. At this time, as the buckle base 21 continues to move, the buckle body 22 is forced to rotate away from the trigger 122 and gradually disengage from the trigger 122. Simultaneously, the trigger 122 loses its obstruction. Under the action of the first spring 121, the ejector guide post 120 is pushed out by the first spring 121, thereby driving the hammer body 11 to strike the animal vertically downward.

[0047] Then, after the buckle base 21 moves to one end of the drive motor 27 and completes one stroke, the drive motor 27 reverses and drives the buckle base 21 to move in the opposite direction along the guide screw 28. When the buckle body 22 moves to the rear of the trigger 122, since there is no obstruction on the side of the buckle body 22 facing the trigger 122, the buckle body 22 will be forced to rotate to the side facing the trigger 122 and pass through the trigger 122. Of course, in order to achieve the reset of the buckle body 22, a torsion spring (not shown in the figure) connected to the buckle base 21 can be installed on the first shaft used to install the buckle body 22 on the buckle base 21, so that after the buckle body 22 passes behind the trigger 122, it can return to the state of being engaged with the trigger 122.

[0048] In this way, the drive motor 27 can be driven to repeatedly cycle through the previous steps, thus achieving continuous striking of the animal.

[0049] In summary, the striking structure provided in this application embodiment, suitable for large animal experiments, can control the frequency of actuation of the ejection assembly 12 by controlling the rotational speed of the drive motor 27, thereby accurately controlling the striking speed on the animal. At the same time, by adjusting the position of the firing assembly 3 to change the compression of the first spring 121, the striking height of the hammer body 11 can be precisely controlled. Furthermore, the energy stored in the hammer body 11 can be precisely controlled by controlling the compression of the first spring 121, thereby precisely controlling the striking force.

[0050] The above description is only a preferred embodiment of this application and is not intended to limit this application. 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.
