[0057] Refer to the attached Figure 1 As shown, an embodiment of the present application provides an adjustable striking device suitable for large animal experiments, including a gantry bracket 100 and a striking mechanism assembly 200. The striking mechanism assembly 200 is fixedly mounted on the gantry bracket 100. The striking mechanism assembly 200 includes a hammer assembly 1, a buckle plate assembly 2 and a firing assembly 3.

[0058] Among them: See Figures 2 to 3As shown, the hammer assembly 1 includes an ejection assembly 12, a guide assembly 13 and a hammer body 11. The ejection assembly 12 is used to store energy to eject the hammer body 11 along the guide assembly 13. Specifically, the guide assembly 13 includes a guide sleeve 130. A guide channel is arranged inside the guide sleeve 130 along its axis, and both ends of the guide channel are closed. The ejection assembly 12 includes an ejection guide column 120 and a first spring 121. The outer diameters of the ejection guide column 120 and the first spring 121 are the same as the inner diameter of the guide channel. The ejection guide column 120 and the first spring 121 are arranged in the guide channel, and in a natural state, the first spring 121 and the ejection guide column 120 occupy the entire guide channel, that is, the sum of the lengths of the first spring 121 and the ejection guide column 120 is the same as the length of the guide channel. At the same time, 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 one end of the ejection guide column 120 away from the first spring 121. The guide channel is located at one end of the connecting shaft 110 and is provided with a through hole that only allows the connecting shaft 110 to pass through. The connecting shaft 110 extends outward through the through hole along the axial direction of the guide sleeve 130 and is fixedly connected to the hammer head 111 located outside the guide sleeve 130.

[0059] See above Figure 2 As shown, both ends of the guide sleeve 130 are fixedly mounted on the gantry bracket 100 through the mounting base 300, and the side wall of the guide sleeve 130 is provided with an axially extending avoidance groove 131, and the side wall of the ejection guide column 120 is provided with a trigger 122 perpendicular to the axial direction of the ejection guide column 120, and the trigger 122 extends out of the guide sleeve 130 from the avoidance groove 131 and is buckled with the buckle plate assembly 2. Figures 2 to 4As shown, the buckle plate assembly 2 includes a buckle plate base 21, a buckle plate body 22, an elastic baffle 23 and a trapezoidal driving block 25. The buckle plate base 21 is installed with a first shaft rod through a bearing, and the buckle plate body 22 is fixedly sleeved on the first shaft rod (not shown in the figure), so that the buckle plate body 22 and the first shaft rod rotate on the buckle plate base 21, and the buckle plate body 22 is away from the first shaft rod. One end is close to the trigger 122, and a buckle hole is provided on the buckle plate body 22, and a buckle hook is provided on the trigger 122. The buckle hole is slightly larger than the buckle hook, and the buckle plate body 22 and the trigger 122 are buckled through the buckle hole and the buckle hook. The gusset base 21 is provided with a slide groove 210 extending in a perpendicular direction, the first direction being a direction parallel to the axis of the guide sleeve 130, the slide groove 210 being located on the side of the gusset body 22 away from the trigger 122, the elastic baffle 23 being installed in the slide groove 210, wherein the elastic baffle 23 comprises a baffle body 230 and a second spring 231, the baffle body 230 being slidably installed in the slide groove 210, the bottom of the baffle body 230 being fixedly connected to the second spring 231, the lower end of the second spring 231 being fixed to the side of the gusset base 21 through a side plate 232. In addition, right-angled folding plates 24 are integrally formed on both sides of the baffle body 230, and trapezoidal driving blocks 25 are integrally formed on the right-angled folding plates 24 on both sides, and the trapezoidal driving blocks 25 protrude toward the trigger 122 side.

[0060] In the above, in order to realize that the gusset assembly 2 drives the ejection assembly 12 to compress the first spring 121 to store energy, as Figure 3 and Figure 4 As shown, the gusset assembly 2 also includes a driving assembly for driving the gusset base 21 to move, wherein the driving assembly includes a first guide rail 26, a guide screw 28 and a driving 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 is provided with a first side groove along the side wall. The gusset base 21 is arranged in the first guide rail 26 and protrudes along the first side groove to form a limit, so that the gusset 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 blocks 261. The guide screw 28 is arranged along the first guide rail 26, and the two ends are connected to the side blocks 261 through bearings. The gusset base 21 is threadedly connected to the guide screw 28, and the driving motor 27 is connected to one end of the guide screw 28 through a coupling. It can be imagined that the movement of the driving motor 27 can drive the buckle plate base 21 to move along the guide screw 28. Since the buckle plate body 22 is buckled with the trigger 122, and the blocking of the baffle body 230 prevents the buckle plate body 22 from rotating away from the trigger 122, the buckle plate base 21 moves to drive the ejection guide column 120 to compress the first spring 121 to store energy.

[0061] In this embodiment, see Figure 3 and Figure 5As 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 the second guide rail 31 is parallel to the trapezoidal drive block 25. The side wall of the second guide rail 31 is provided with a plurality of positioning screw holes along the length direction. 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 is also provided with a second side groove along the side wall. The slide 32 is slidably installed in the second guide rail 31 and protrudes into the second side groove, so that the slide 32 is limitedly installed in the second guide rail 31 and does not fall out. A positioning bolt 36 is provided on the slide 32. The slide 32 can be positioned by screwing the positioning bolt 36 into the positioning screw hole when the slide 32 moves to different positions. An L-shaped plate 33 is fixedly provided on the upper end surface of the slide 32, and a trapezoidal stopper 34 adapted to the trapezoidal drive block 25 is provided at the bottom of the transverse plate section of the L-shaped plate 33. It can be imagined that when the trapezoidal drive block 25 contacts the trapezoidal stopper 34, the baffle body 230 is first pressed downward and then bounced upward.

[0062] Of course, it is understandable that in a preferred embodiment, in order to facilitate the screwing of the positioning bolt 36 , a hexagonal countersunk hole is provided on the outer end surface of the positioning bolt 36 , so that the positioning bolt 36 can be screwed conveniently using a hexagonal wrench.

[0063] Based on the above, when conducting large animal striking experiments:

[0064] First, use a hexagonal wrench to screw out the positioning bolt 36 and separate it from the second guide rail 31 and the slide 32 at the same time. According to the need of the striking force, move the slide 32 to the corresponding positioning screw hole. After the slide 32 moves to the specified point, screw the positioning bolt 36 into the corresponding positioning screw hole to fix the position of the slide 32. At this time, the length by which the first spring 121 can be compressed is determined, so that the striking force and striking height are set.

[0065] Next, the driving motor 27 is started to drive the guide screw 28 to rotate forward, and the clasp base 21 drives the clasp body 22 to move along the guide screw 28 toward the driving motor 27. Since the clasp body 22 is buckled with the trigger 122 and the clasp body 22 is blocked by the baffle body 230 and cannot rotate away from the trigger 122, the ejection guide column 120 moves along the guide channel toward the first spring 121 under the drive of the clasp body 22, thereby compressing the first spring 121. When the clasp body 22 moves to the trapezoidal driving When the block 25 contacts the trapezoidal stop block 34, the trapezoidal driving block 25 is compressed and drives the baffle body 230 to move along the slide groove 210 to compress the second spring 231 to provide space for the rotation of the pinch plate body 22. At this time, as the pinch plate base 21 continues to move, the pinch plate body 22 is forced to rotate away from the trigger 122 and gradually disengage from the trigger 122. The synchronous trigger 122 loses its blockage, and the ejection guide column 120 is pushed out by the first spring 121 under the action of the first spring 121, thereby driving the hammer head 11 to vertically downward to hit the animal;

[0066] Then, after the gusset base 21 moves to one end of the driving motor 27 and completes a stroke, the driving motor 27 reverses and drives the gusset base 21 to move in the opposite direction along the guide screw 28. When the gusset body 22 moves to the rear of the trigger 122, since the gusset body 22 is unobstructed on the side of the trigger 122, the gusset body 22 is forced to rotate toward the side facing the trigger 122 and pass through the trigger 122. Of course, in order to realize the reset of the gusset body 22, a torsion spring (not shown in the figure) connected to the gusset base 21 can be installed on the first shaft used to install the gusset body 22 on the gusset base 21, so that the gusset body 22 can be restored to an upright state after passing through the rear of the trigger 122.

[0067] In this way, the driving of the driving motor 27 can realize the repeated cycle of the previous step, and realize continuous hitting of the animal. Of course, it should be noted that during the hitting experiment, the animal being hit is in a restrained state, such as being locked in a cage, with a hole reserved for the hammer head 11 to enter, and the animal's limbs are restrained and tied to prevent the animal from accidentally injuring others when being hit.

[0068] It can be seen that by controlling the rotation speed of the driving motor 27, the frequency of turning the ejection component 12 can be controlled, so as to accurately control the speed of hitting the animal. At the same time, by adjusting the position of the firing component 3, the compression amount of the first spring 121 is changed, so as to accurately control the hitting height of the hammer head 11. At the same time, the compression amount of the first spring 121 is used to control the energy storage energy of the hammer head 11, so as to accurately control the hitting force.

[0069] In a preferred embodiment, in order to improve the practicability of the striking device, the striking device provided in the embodiment of the present application can be applied to striking experiments of large animals of various sizes. Figure 1As shown, in this embodiment, the striking mechanism assembly 200 is fixed to the mounting base 300 via the variable diameter adjustment mechanism 400 , and the mounting base 300 is fixed to the gantry bracket 100 .

[0070] Specifically:

[0071] like Figure 1 As shown, in order to adapt to large animals of different sizes, the height of the gantry support 100 is adjustable, not limited to the following embodiments, the gantry support 100 includes a base support 101 and an adjustment support 102, the base support 101 is provided with a slot along the longitudinal direction, and the adjustment support 102 is inserted into the slot to form a movable connection with the base support 101. Side panels are provided on the sides of the base support 101 and the adjustment support 102, and a first electric telescopic rod 103 is installed between the side panels. The height adjustment of the gantry support 100 is achieved by the extension and contraction of the first electric telescopic rod 103, so as to adapt to animals of different sizes. It should be noted here that when the first electric telescopic rod 103 is at the maximum extension, the base support 101 and the adjustment support 102 are still connected and not separated, and the width of the gantry support 100 is sufficient, and there is no need to adjust the spacing when using it.

[0072] On the basis that the height of the gantry bracket 100 is adjustable, in order to adapt to large animals of different sizes, it is also necessary to replace the striking mechanism assembly 100 with a suitable size according to the different sizes of animals, and the hammer assembly 1, as a direct actuator assembly for striking the animal, needs to be designed in size according to the animal's size, so the hammer assembly 1 has a variety of models with different diameters, and the hammer assembly 1 of the corresponding size is selected according to large animals of different weight ranges to obtain a suitable striking area. It is easy to understand that the larger the animal, the larger the hammer head 11, and the larger the diameter of the guide sleeve 130 used to install the hammer head 11.

[0073] Therefore, in order to facilitate the installation of different types of hammer assemblies 1, see Figure 6 and Figure 7 As shown, in the striking mechanism assembly 100, the guide sleeve 130 is fixed to the mounting base 300 through the variable diameter adjustment mechanism 400. Specifically, the variable diameter adjustment mechanism 400 includes a fixing seat 41, a fixing sleeve 42, a diameter adjustment component 43 and an adjustment component 44. Among them, the fixing seat 41 is integrally formed with a right-angle mounting portion, and the right-angle mounting portion is fixedly mounted on the mounting base 300 by bolts. The fixing seat 41 is centrally provided with an axial through hole, and the fixing sleeve 42 can be installed in the axial through hole by a bearing connection and rotate. The fixing sleeve 42 is axially provided with a fixed cavity, and when in use, the guide sleeve 130 penetrates into the fixed cavity, and the clamping caliber size is changed by adjusting the diameter adjustment component 43, so as to clamp hammer assemblies 1 of different sizes.

[0074] In the above embodiment, if Figure 6 and Figure 7 As shown, the diameter adjustment component 43 includes an adjustment arm 430, a limiting sleeve 431 and a roller 432. Among them, a connection hole 46 is provided at one end of the adjustment arm 430, and a step shaft 45 is fixedly provided on the side of the fixed seat 41 facing the diameter adjustment component 43. The step shaft 45 is installed in the connection hole 46 by means of a bearing connection, so that the adjustment arm 430 can rotate on its own with the step shaft 45 as the axis. The other end of the adjustment arm 430 passes through the limiting sleeve 431 and extends into the fixed cavity. A U-shaped wheel frame is provided at one end of the adjustment arm 430 located in the fixed cavity, and the roller 432 is rotatably installed on the U-shaped wheel frame through the wheel axle. In addition, a shaft body 410 is integrally formed on the side of the limiting sleeve 431 facing the fixed seat 41, and the shaft body 410 is connected to the fixed sleeve 42 by means of a bearing connection.

[0075] In the above embodiment, the adjustment assembly 44 includes a first base 440, a second base 441 and an adjustment shaft 442, wherein the first base 440 is fixedly connected to the fixed base 41, the second base 441 is connected to the fixed sleeve 42, an ear plate 47 is integrally formed on the outer wall of the fixed sleeve 42, an axial hole 48 is provided on the ear plate 47, and a pin 49 is integrally formed on the second base 441, and the pin 49 is rotatably installed in the axial hole 48 by a bearing connection. In the above, the first base 440 is provided with a smooth through hole, and the second base 441 is provided with a threaded through hole. At the same time, the adjustment shaft 442 includes a smooth rod section and a screw rod section, the smooth rod section passes through the smooth through hole to form a smooth connection with the first base 440, and baffles are integrally formed at both ends of the smooth rod section, so that the axis position of the first base 440 and the smooth rod section is limited, ensuring that the smooth rod section can only rotate but cannot move forward and backward. The screw rod section is threadedly connected with the second base 441 through the threaded through hole.

[0076] Based on the above content, it can be imagined that when it is necessary to adjust the clamping diameter formed by the diameter adjustment component 43, the operation steps are as follows:

[0077] First, the user rotates the adjusting shaft 442 through the handle at the end of the smooth rod section. The rotation of the adjusting shaft 442 causes the second base 441 to move along the screw section. Since the second base 441 is rotatably connected to the fixed sleeve 42, the movement of the second base 441 causes the fixed sleeve 42 to rotate. The fixed sleeve 42 is connected to the limiting sleeve. The rotation of the fixed sleeve 42 causes the adjusting arm 430 to telescope under the limitation of the limiting sleeve 431. As the adjusting arm 430 telescopes and moves, the size of the clamping aperture is changed, thereby achieving the purpose of clamping hammer assemblies 1 of different sizes.

[0078] It should be noted here that Figure 1As shown, in order to prevent the variable diameter adjustment mechanism 400 from slipping during the process of clamping the guide sleeve 130, a circle of sliding grooves can be optionally provided on the outer wall of the guide sleeve. During the clamping process, the roller 432 is located in the sliding groove and fits against the outer wall of the sliding groove, and the step surfaces on both sides of the sliding groove are used to support the adjustment arm 430 to limit the slippage of the guide sleeve 130.
