[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the utility model should be the common meanings understood by people with ordinary skills in the field to which the disclosure belongs.

[0037] As described above, traditional devices are limited by the spacing of the "fixing holes", which means that they can only be used to secure small animals of specified sizes. In addition, they are difficult to fold when not in use and require a certain amount of storage space.

[0038] In order to at least partially solve the above-mentioned problems and one or more of other potential problems, an exemplary embodiment of the utility model proposes an animal restraint device, which can be raised and lowered according to the height of the restrained animal through a supporting structure, so that the animal's limbs can touch the ground to ensure the animal's safety and prevent the stress caused by high altitude; the load-bearing structure adopts flexible materials that conform to the animal's body structure, so that the restraint process meets the animal's welfare, the restraint process is safer, and can meet the needs of restraint for animals of different sizes; the second limiting structure can adjust the length according to the body size of the restrained animal to make the restraint more secure and reduce the animal's stress; the adjustment structure can fold the device to improve portability and reduce the storage space occupied when idle.

[0039] The following combination Figure 1-Figure 5 An exemplary illustration of an animal restraint device. Figure 1A schematic diagram of the top view of the structure of an animal restraint device according to some embodiments of the utility model is shown. Figure 2 The figure shows a front view structural schematic diagram of an animal restraint device according to some embodiments of the utility model. Figure 3 Some embodiments of the utility model Figure 1 Schematic diagram of the structure in a partially truncated state. Figure 4 Some embodiments of the utility model Figure 1 Schematic diagram of the structure after partial truncation and enlargement. Figure 5 Some embodiments of the utility model Figure 2 The schematic diagram of the structure after partial truncation and enlargement. The animal restraint device includes a support structure 100, an adjustment structure 200, a bearing structure 300, a first limiting structure 400 and a second limiting structure 500. The adjustment structure 200 adjusts the support structure 100 to a corresponding size according to the size of the restrained animal, and then adjusts the support structure 100 according to the height of the restrained animal. By adjusting the first limiting structure 400, the support structure 100 can open the bearing structure 300 flatly under the premise of a specific size, so that the device is in a working state for restraining animals. Then, the restrained animal is placed on the bearing structure 300, and the animal is fixed with the second limiting structure 500 so that the animal is restrained on the device.

[0040] Regarding the support structure 100 (see attached Figure 1-3 As shown in FIG. 1 , the cylinder 101 includes four cylinders 101 and fixing members 102 mounted on the cylinders 101. The positions of the fixing members 102 on the cylinders 101 are adjusted to change the cylinders 101 in the first direction (indicated by Figure 2 The height of the coordinate "Z" axis).

[0041] Furthermore, the column 101 includes at least three sections sequentially connected along the first direction, and can also be composed of four sections, five sections or more, or can be composed by stacking in the first direction, for example, the structure can be composed by directly connecting two adjacent sections, and the present application does not limit this.

[0042] The at least three sections are all on a side surface along the first direction (with Figure 2 For example, the side surface (referring to the front surface) is provided with a plurality of locking holes 103 for connecting the fixing member 102, and the locking holes 103 are arranged on the column 101 along the second direction ( Figure 1 The coordinate "Y" axis) passes through, specifically, taking a group of locking holes 103 as an example, a group of locking holes 103 includes Figure 1The viewing angle passes through two corresponding circular holes on the coordinate "Y" axis of the column 101. When the height of the column 101 is adjusted, two groups of locking holes 103 in the two adjacent sections in the coordinate "Z" axis direction are moved up and down so that the two groups of locking holes 103 are aligned on the coordinate "Y" axis. At this time, the alignment state of the two groups of locking holes 103 satisfies the connection of the fixing member 102. After the fixing member 102 is connected, the height of the adjacent two sections can be limited, so that the height of the entire column 101 is changed, that is, raised or lowered, so as to meet the height of the animal restraint, so that the animal's limbs can land, ensure the safety of the animal and prevent the stress caused to the animal by high altitude.

[0043] In some embodiments, the column 101 is a square tube structure. Under the premise that multiple sections can be socketed on the coordinate "Y" axis, the diameter of the square tube is gradually reduced from bottom to top. Of course, the diameter can also be gradually reduced from top to bottom. And because the square tube is a square with four faces, the locking hole 103 is still on the coordinate "Z" axis during the up and down adjustment of multiple sections of the square tube.

[0044] In some embodiments, the cylinder 101 is a circular tube structure. Under the premise that multiple sections can be socketed on the coordinate "Y" axis, the diameter of the circular tube is successively reduced from bottom to top or from top to bottom. It should be noted that when it is a circular tube, the multiple sections of the circular tube are provided with directional grooves so that the multiple groups of locking holes 103 correspond in the first direction. Specifically, in the socketed state, the directional groove of one section of the circular tube wraps or is wrapped on the directional groove of another section of the circular tube. Through the setting of the directional grooves, when the multiple sections of the circular tube are moved up and down, the multiple sections of the circular tube will not rotate, so that the locking holes 103 are still on the coordinate "Z" axis.

[0045] In some embodiments, the fixing member 102 is at least two bolt assemblies located on multiple groups of locking holes 103. Specifically, the bolt assembly includes at least a screw and a nut. The screw is placed in two groups of locking holes 103 of two adjacent sections of the column 101, and one end of the screw is exposed, and the nut is screwed on one end of the screw, so that the height of the upper and lower sleeves of the two adjacent sections of the column 101 are fixed by the bolt assembly.

[0046] In some embodiments, the fixing member 102 is a latch assembly, specifically, the latch assembly includes a pin and an anti-dropout rod, the pin is placed in the locking hole 103, and one end of the pin is exposed, and the anti-dropout rod is placed at one end of the pin.

[0047] That is, the height at which two adjacent sections of the column 101 are connected up and down is reached by fixing the bolt assembly.

[0048] Regarding the adjustment structure 200 (see attached Figure 2 and Figure 3As shown), it includes a central connecting body 201, a connecting rod 202 hinged between the central connecting body 201 and four columns 101, and at least four diagonal bracing rods 203 connected between the four connecting rods 202 and the columns 101, one end of the diagonal bracing rod 203 is slidably connected to the connecting rod 202, and the other end is detachably connected to the column 101. When in use, the other end of the diagonal support rod 203 is disconnected from the column 101 and is subjected to upward or downward force on the central connecting body 201, or the column 101 is subjected to inward or outward force, so that the central connecting body 201 moves on the coordinate "Z" axis, thereby simultaneously changing the angle between the connecting rod 202 and the column 101. For example, the angle between the connecting rod 202 and the column 101 is deformed from 40° to 110° or from 110° to 40°, so that the central connecting body 201 is simultaneously away from or close to the four columns 101, thereby making the spacing between the four columns 10 equally expanded or reduced, thereby changing the length and width of the square bearing surface covered by the four columns 101.

[0049] Furthermore, both ends of the connecting rod 202 are respectively hinged to the central connecting body 201 and the column 101 through a damping shaft, which can provide a certain resistance force after the connecting rod 202 is unfolded, that is, it can fix the square bearing surface covered by the four columns 101 without external pressure.

[0050] One end of the diagonal support rod 203 is slidably connected to the connecting rod 202 through a damping sliding sleeve. After the opening or closing angle of the connecting rod 202 is roughly determined, the damping sliding sleeve is pushed to move along the determined angle of the connecting rod 202 to change the position of one end of the diagonal support rod 203 on the connecting rod 202;

[0051] The other end of the diagonal support rod 203 is detachably connected to the column 101 through the plug-in piece 204 to change the position of the diagonal support rod 203 on the column 101. By changing the position of one end and the other end of the diagonal support rod 203 on the connecting rod 202 and the column 101, the angle of the diagonal support rod 203 between the connecting rod 202 and the column 101 is changed. For example, the inclination angle is expanded or reduced. In this state, the diagonal support rod 203 can fix the angle of the connecting rod 202 after opening or closing, thereby fixing the square bearing surface covered by the four columns 101 after deformation.

[0052] Further, the connector 204 (see attached Figure 5 As shown in the figure, the plurality of groups of insertion holes 2041 are provided on the column 101, and the plurality of groups of insertion holes 2041 are staggered with the plurality of locking holes 103 in the circumferential direction of the column 101. Specifically, the opening position of the side insertion holes 2041 can be roughly determined by observing the position of the locking holes 103.

[0053] And the insert block 2042 can be placed on the multiple groups of sockets 2041. The insert block 2042 is hinged to one end of the diagonal support rod 203 through a damping shaft. The insert block 2042 is inserted into the socket 2041 to determine the diagonal support angle of the diagonal support rod 203, thereby locking the opening angle of the connecting rod 202.

[0054] Regarding the bearing structure 300 (see Figure 1 and Figure 2 As shown), it includes a rectangular section 301, and a trapezoidal section 302 located at both ends of the rectangular section 301 along the second direction, and at least three fixing holes 303 are opened between one of the trapezoidal sections 302 and the rectangular section 301, and the fixing holes 303 are used to insert the mouth of the animal. The number of fixing holes 303 is not limited to three, and can also be four or more, and the present application does not impose any restrictions on this. When in use, the rectangular section 301 is used to support the body of the animal, specifically, the body part within the limbs of the animal. Here, the limbs of the animal are located on both sides of the rectangular section 301 (referring to the other two sides that are not connected to the trapezoidal section 302). According to the size of the animal, while ensuring that the animal is in the middle of the overall load-bearing structure 300, the mouth of the animal is inserted into the fixing hole 303 of a size that matches it;

[0055] It also includes: at least three groups of flexible strips 304 (see attached Figure 2 As shown in the figure, it is connected to at least three fixing holes 303, and the number is relatively adjusted according to the number of fixing holes 303; it is used to bind the mouth of an animal located in the fixing hole 303. For example, a group of flexible long strips 304 includes two or more rope bodies, and is connected to the fixing hole 303 along the second direction or the third direction (the coordinate "X" axis), that is, it is equidistantly arranged around the fixing hole 303 in the axial direction.

[0056] In some embodiments, the flexible strip 304 is a nylon belt (not shown in the figure) with adjustable length and a certain width, one end of which is fixedly connected to the bearing structure 300, and the other end is detachably connected to the bearing structure 300. Specifically, the width of the middle part of the nylon belt is much larger than the width of the two ends, and is connected near the fixing hole 303 along the coordinate "Y" axis. When the mouth of the animal is placed in the fixing hole 303, the nylon belt can be passed around the top of the animal's head for fixed connection, thereby blocking the animal's head and limiting the animal's mouth in the fixing hole 303. It should be noted that the method of binding the mouth or fixing the head is acceptable, and other methods that can roughly limit the animal's head on or near the fixing hole 303 are also acceptable.

[0057] Regarding the first limiting structure 400 (see Figure 4As shown), it includes four belt bodies 401 connected to two trapezoidal segments 302, the length of the belt body 401 is adjustable, and the other end is respectively connected to four columns 101, so that the bearing structure 300 is located on the supporting structure 100 through the first limiting structure 400.

[0058] Furthermore, the size of the rectangular section 301 is preferably 15-40CM in length and 10-25CM in width, and the ratio of the maximum length of the trapezoidal section 302 to the width of the rectangular section 301 is 1.2:1.

[0059] In some embodiments, the supporting structure 300 as a whole is manufactured into multiple specific sizes, and each size of the supporting structure 300 can be used to restrain and support animals of slightly different sizes. This facilitates flexible replacement and disassembly for cleaning through the first limiting structure 400 in actual use.

[0060] Furthermore, the first limiting structure 400 (see Figure 4 The four belts 401 shown in the figure include a first connecting section 4011 and a second connecting section 4012, wherein the first connecting section 4011 is adjustable in length and is detachably connected to the second connecting section 4012, so that the overall length of the belt 401 can be adjusted. In this way, even if the size of the bearing structure 300 is too smaller than the unfolded size of the supporting structure 100, the bearing structure 300 can be smoothly unfolded to carry the animal by adjusting the length of the belt 401.

[0061] Furthermore, it also includes: a plug-in fastener 402, which is located between the first connection section 4011 and the second connection section 4012, and is used to detachably connect the first connection section 4011 and the second connection section 4012. Specifically, the plug-in fastener 402 includes a "mountain"-shaped plug and a connector, wherein both sides of the plug can be elastically pressed inward to be able to enter the connector, and after entering the connector, both sides of the plug are reset and stuck in the connector to complete the connection. When disconnecting, both sides of the plug are also pressed to make both sides of the plug disengage from the fixed parts in the connector. The plug is connected to one end of the second connection section 4012, and the connector is connected to one end of the first connection section 4011.

[0062] The Japanese-shaped buckle 403 is connected to the first connecting section 4011, and the position of the Japanese-shaped buckle 403 on the first connecting section 4011 is adjusted. Specifically, the other end of the first connecting section 4011 passes around the middle cross bar of the Japanese-shaped buckle 403, passes through the upper connecting ring of the column 101, and is finally fixedly connected to the middle cross bar of the Japanese-shaped buckle 403, so that a part of the length of the first connecting section 4011 is folded in half. In this way, by moving the position on the Japanese-shaped buckle 403, the length of the first connecting section 4011 that is folded in half is further increased or shortened, thereby shortening or increasing the overall length of the first connecting section 4011. After the length of the first connecting section 4011 is adjusted by the Japanese-shaped buckle 403, the bearing structure 300 connected to the second connecting section 4012 can be not limited by the unfolding size of the supporting structure 100, and the bearing structure 300 can be flatly opened. That is to say, when there is a certain gap between the bearing structure 300 and the supporting structure 100, the gap can be compensated and connected by the first limiting structure 400 by adjusting its own length.

[0063] Regarding the second limiting structure 500 (see Figure 5 As shown in FIG. 1 , the second limiting structure 500 includes a belt body 401 connected to the rectangular section 301 of the bearing structure 300, and the belt body 401 is consistent with the belt body 401 of the first limiting structure 400 (for details, please refer to the detailed description of the belt body 401 of the first limiting structure 400 above). However, the second limiting structure 500 is different from the first limiting structure 400 in that the second limiting structure 500 is connected to the rectangular section 301 of the bearing structure 300, and its function is to limit the animals located on the bearing structure 300.

[0064] In some embodiments, the second limiting structure 500 includes two belt bodies 401 , and the two belt bodies 401 are staggeredly connected on the rectangular segment 301 in an “X” shape to cross-cover the animal body part located on the rectangular segment 301 .

[0065] In some embodiments, the second limiting structure 500 includes at least two belt bodies 401, and the number of belt bodies 401 can also be three or more, which is not limited in the present application. The number of belt bodies 401 is connected to the rectangular segment 301 at intervals along the second direction, and is used to vertically cover the animal body part located on the rectangular segment 301.

[0066] A person skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present disclosure (including the claims) is limited to these examples. In accordance with the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0067] The embodiments of the present invention are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims.
