Description

Technical Field

[0001] The invention relates to the technical field of animal inspection and quarantine equipment, and in particular to a restraining device for animal quarantine blood drawing. Background Art

[0002] Animal restraint devices are mainly used to immobilize animals during animal medical treatment, experiments or other processing to ensure personnel safety and improve operational efficiency. These devices can be divided into many types, including but not limited to physical restraint, chemical restraint and mechanical restraint. Physical restraint usually refers to the fixation of animals by manpower or simple equipment (such as ropes, bandages, etc.); chemical restraint is to calm the animal by giving it sedatives or anesthetics; mechanical restraint involves more complex devices, such as restraint racks, restraint cages, etc.

[0003] For physical restraint, common restraint devices mainly include animal head fixation and limb fixation. Therefore, there are many studies on animal limb and head and neck fixation devices. However, for animals, the main part of their body is the trunk, especially for larger animals, the trunk accounts for almost 80% of their volume and weight. Even if the head, neck and limbs are fixed, once they break free and escape, it is difficult to control them. Moreover, in practice, when inspecting and quarantine animals, the most basic thing is to check the appearance of the animals, which is also the most basic inspection content, observing the fur, mental state, etc. If the trunk is not well fixed, it is difficult to get close to check.

[0004] In addition, the existing restraint devices usually use a restraint method similar to that used for the head, neck and limbs for the animal trunk, that is, a roughly annular device is used for circumferential binding. This type of structure can easily cause the animal to swing under the influence of the spine, or damage the spine during forced swinging, resulting in immeasurable harm, given the slender animal trunk. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a restraining device for animal quarantine blood drawing, so as to solve the problem in the prior art that when restraining an animal, the trunk cannot be safely and effectively fixed, resulting in the fixation of other parts being affected.

[0006] The present invention is achieved through the following technical solutions:

[0007] A restraining device for blood drawing for animal quarantine, comprising a platform for animals to stand on, comprising a trunk fixing assembly, wherein the trunk fixing assembly comprises driving screws located at left and right sides of the platform, wherein the driving screws are vertically installed, wherein a threaded sleeve is coaxially rotatably mounted on the top of the driving screws, wherein the threaded sleeve is threadedly sleeved on a horizontally installed screw rod, wherein the screw rod is rotatably mounted around its axis in a horizontally arranged crossbeam, wherein the bottom surface of the crossbeam is provided with a strip-shaped sliding hole in the horizontal direction, wherein a rack parallel to the strip-shaped sliding hole is fixed to the rear side of the bottom port of the strip-shaped sliding hole;

[0008] A cylindrical gear is fixed to the driving screw rod just below the strip-shaped sliding hole, and the cylindrical gear is meshed with the rack; a pair of hydraulic rods are symmetrically threadedly sleeved on each driving screw rod, and a splint with an overall hollow structure is fixed to the telescopic end of each hydraulic rod, the splint has an arc-shaped cross-section and the concave surfaces of the two splints face each other, and when the screw rod rotates, the two driving screw rods can be brought together in a straight line while rotating, so that the two splints are brought together in the horizontal and vertical directions at the same time, so that the upper and lower splints clamp the trunk of the animal between them.

[0009] Furthermore, the end of one of the splints has an inner expansion cavity recessed outward, so that when the two splints are brought together horizontally, one of the splints can be inserted into the inner expansion cavity; the rising height of the lower splint can lift the animal's limbs off the platform surface.

[0010] Furthermore, a sliding rod is horizontally fixed on the side wall of the inner expansion cavity, and the sliding rod is axially slidably matched with the socket at the end of the opposite clamping plate; on the side wall of the inner cavity or the end face of the opposite clamping plate, at least one of the surfaces is installed with a distance sensor to detect the distance between the two.

[0011] Furthermore, the inner surface of the splint has an elastic airbag tile, which is fixedly attached to the inner wall of the splint as a whole, and the elastic airbag tile is connected to the compressed air source through a control valve; a pressure gauge for detecting the real-time pressure is installed on the elastic airbag tile, and the pressure gauge is connected to an alarm. When the pressure gauge exceeds the set value, the alarm will sound.

[0012] Furthermore, a driving screw is provided at the rear or front of each side in the left-right direction of the platform, and the telescopic rod section of the hydraulic telescopic rod is Z-shaped.

[0013] Furthermore, a driving screw is provided at the front and rear of each side in the left and right directions of the platform, and the telescopic rod section of the hydraulic telescopic rod is a straight rod structure; a pillow beam is fixed on the outer surface of each end of the splint perpendicular to its axis, and the telescopic rod section is vertically fixed at both ends of the pillow beam.

[0014] Furthermore, the bottom end of the driving screw is horizontally slidably mounted on a slide, a horizontally rolling roller is provided at the bottom of the slide, the roller can be self-locking, and the slide is installed under the platform, the platform is installed on the ground through supporting feet, and the two ends of the beam are respectively fixedly connected to the two sides of the slide.

[0015] Furthermore, a hydraulic telescopic column is installed at the bottom of the skateboard, and the supporting foot has a vertical telescopic structure capable of changing the height of the platform.

[0016] Furthermore, a mark rod is horizontally fixed between the left and right opposite driving screws, and when the corresponding driving screws are close to each other, the mark rod on one side can be axially slidably inserted into the mark rod on the other side, and the mark rod is located in the center between the upper and lower clamping plates.

[0017] Furthermore, four hollow guardrail plates are mounted around the surface of the platform through telescopic shaft supports. The guardrail plates can rise vertically to a position close to the trunk of the animal after the trunk of the animal is clamped up and down by the splints.

[0018] The beneficial effects of the present invention are:

[0019] The restraining device for animal quarantine blood drawing drives the animal onto a platform, and then uses a splint that is linked horizontally and vertically from a distance to press and fix the animal through the abdomen and back. Since the splint has a certain length, it can achieve a large coverage and compression of the animal's trunk length direction, so it can have a better fixation effect and is not easy to hurt the animal itself. In layman's terms, it will not be strangled like the traditional round hoop fixation method, and the contact area is larger. In addition, the length of the spine of the restricted animal can cover the entire spine, so it is not easy to form a traditional two-section circular hoop tightening structure. When the two ends of the trunk are alternately covered, the trunk will swing obviously and violently. It has a certain restraint on the animal, but it will not hurt the animal itself due to the small contact range. In addition, the splint gradually moves from an area far away from the animal on the platform, and gradually passes through the bottom between the two legs under the neck and buttocks, which is not easy to cause excessive fright to the animal. In addition, because the animal quarantine blood drawing restraint device of the present invention can keep the animal off the ground as a whole when in use, the animal's limbs lack fulcrums, and thus even if the trunk shakes, the amplitude of the shaking is relatively greatly reduced.

[0020] The present invention can be used as a special restraint device for a certain type of animals during mass breeding. The splint can be specially customized to achieve the best restraint effect. Compared with some existing devices that use the same restraint method for the head, neck and limbs, it can fully fix the animals without making them feel obviously uncomfortable and restrained.

[0021] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] See also Figure 1-2 The present invention provides a technical solution: a restraining device for animal quarantine blood drawing, which mainly includes a platform 1 for animals to stand on, so as to drive the animals to the platform 1, and also includes a trunk fixing component and a head fixing component, wherein the head fixing component in this embodiment can be a plurality of limit plates (not shown in the figure) connected to the surrounding hydraulic telescopic elements, and the hydraulic telescopic elements are started, so that all the limit plates limit the head from different directions, or surround the neck and the part close to the head, so as to achieve the purpose of fixing the animal's head, so as to prevent the head and neck from shaking when blood is drawn from the neck. In addition, in the prior art, for the head component, the animal head fixer for livestock or the like involved in the existing patent technologies with publication numbers CN213758705U, CN115462326A, CN219814403U, CN213758705U, and CN218922871 U, or the head fixing component of the recorded animal restraint equipment can be used to adaptively implement the improvement and production. The animal quarantine blood collection device in this embodiment is mainly used to fix the trunk of the animal. Figure 1-2 The trunk fixing assembly includes driving screws 2 located on the left and right sides of the platform 1. The driving screws 2 are installed vertically. Each driving screw 2 is provided with upper and lower sections of threads with opposite rotation directions. A threaded sleeve 7 is installed on the top of the driving screw 2 in a coaxial rotational manner. The rotation direction of the threaded sleeve 7 is consistent with the corresponding threaded section. The threaded sleeve 7 is connected to a horizontally installed screw rod 6, such as Figure 3 The screw rod 6 is rotatably installed around its axis in a horizontally arranged crossbeam 11, which is located above the platform 1, and a strip-shaped sliding hole 1101 is provided in the horizontal direction on the bottom surface of the crossbeam 11. A rack 5 parallel to the strip-shaped sliding hole 1101 or the screw rod 6 is specially fixed on the rear side of the bottom end of the strip-shaped sliding hole 1101. When the screw rod 6 is specifically manufactured, it can be driven to rotate by a driving motor (not shown in the figure) installed at one end of the crossbeam 11. When the trunk of the animal is fixed, the animal as a whole is basically in a state of confinement. At this time, veterinarians and other staff can more conveniently observe the general appearance of the local appearance of the animal's body, check whether there is hair loss, psoriasis, ulceration and other epidemic diseases, and if necessary, blood sampling can be performed on specific parts. Moreover, after the trunk is fixed, it can be more convenient to use the corresponding existing tools to selectively choose whether to restrain or fix the head or limbs, which lays the foundation for the rapid and convenient fixation of other parts.

[0032] like Figure 1As shown, in this embodiment, a cylindrical gear 4 is fixed just below the driving screw 2 near the strip-shaped sliding hole 1101, and the cylindrical gear 4 is meshed with the rack 5. In addition, each driving screw 2 is symmetrically threaded with a pair of hydraulic rods 7, and a clamping plate 8 with an overall hollow structure is fixed to the telescopic end of each hydraulic rod, so that the surface of the animal inside the clamping plate 8 can be viewed through the hole. The cross section of the clamping plate 8 is arc-shaped and the concave surfaces of the two clamping plates 8 face each other to clamp the animal trunk. During use, when the screw rod 6 rotates, the two driving screw rods 2 can be brought together in a straight line, and because of the meshing relationship between the cylindrical gear 4 and the rack 5, they can also rotate on their own, so that the two clamping plates 8 can be brought together in the horizontal direction and the vertical direction at the same time, that is, they gradually move from the periphery of the platform 1 to the surrounding of the animal and implement clamping and securing, that is, the upper and lower clamping plates 8 clamp the trunk part of the animal between the two. For animals with small horns, the head and neck of the animal can be clamped when necessary to restrict the head and neck to a certain extent, or when implementing it, directly as Figure 1 As shown, a head cover 18 is provided at the right end of the right splint 8. The head cover 18 is in a gourd shape and can be hinged at the end of the splint 8. When necessary, it can be rotated downward to press the animal's head to prevent it from raising its head and injuring people.

[0033] In this embodiment, in order to make it possible for the two plywood plates 8 to overlap when necessary, they can be Figure 1-2 As shown, at the end of one side of the splint 8 there is an inner expansion cavity 9 which is recessed toward the outside. This inner expansion cavity 9 allows one of the splints 8 to fit into the inner expansion cavity 9 when the two splints 8 are brought together in the horizontal direction, thereby shortening the horizontal length of the splint 8 to accommodate slightly smaller animals. At the same time, it can also improve the bearing capacity of the splint 8. During use, the lower splint 8 can be raised to a height that allows the animal's limbs to be lifted off the surface of the platform 1, lifting the animal off the ground as a whole. In this way, the animal is suspended in the air, is less likely to have a force point, is easier to control, and the impact vibration on the splint 8 is also greatly reduced. In order to enhance the above effects, such as Figure 1 and Figure 2 A slide bar 20 is horizontally fixed on the side wall of the inner expansion cavity 9, and the slide bar 20 is axially slidably matched with the jack at the end of the opposite clamping plate 8 to better connect them together. A distance sensor is installed on the surface of at least one of the side wall of the inner cavity or the end face of the clamping plate 8 opposite to it to detect the distance between the two, so as to avoid the problem of clamping the abdomen of the animal when the distance between the two is too small. Once the distance is too small, it should be observed whether there is a sign of squeezing the abdomen of the animal. After eliminating such signs, the two clamping plates 8 are moved closer.

[0034] In this embodiment: Figure 4The inner surface of the splint 8 has an elastic airbag tile 10, which is fixedly arranged on the inner wall of the splint 8. The elastic airbag tile 10 is connected to the compressed air source through a control valve to adjust the appropriate air pressure to form different restraints for different animals, while avoiding the discomfort caused by contact with rigid materials. It also has a certain degree of adaptability to wrap and cover different animals. The elastic airbag tile 10 will gradually deform adaptively according to the shape of the animal's trunk as it is inflated. Specifically, a pressure gauge for detecting the real-time pressure value should be installed on the elastic airbag tile 10. The pressure gauge is connected to an alarm. When the pressure gauge exceeds the set value, the alarm sounds, which means that the animal has been clamped tightly. If the clamping force is further increased, the animal may be injured.

[0035] In the above embodiment, the driving screw 2 may be provided with a screw at the rear or front of each side in the left-right direction of the platform 1, such as Figure 5 The telescopic rod section of the hydraulic telescopic rod 3 is Z-shaped to prevent the driving screw 2 from blocking the center of the path on which the animal enters the platform 1.

[0036] As an optimal implementation structure, the driving screw rod 2 is provided with one at the front and rear of each side in the left and right directions of the platform 1, that is, two at the front and rear of the left side and two at the front and rear of the right side, four at one side, and correspondingly, one at the front and rear of the cross beam 11, and the telescopic rod section of the hydraulic telescopic rod 3 can be a straight rod structure. Figure 6 As shown, during installation, a bolster 19 is fixed on the outer side of each end of the splint 8 perpendicularly to its axis to support the entire splint 8. Correspondingly, the telescopic rod sections are vertically fixed to the two ends of the bolster 19, thereby driving the splint 8 to move. In this way, when fixing the animal trunk, the hydraulic telescopic rod 3 can be used for better fine-tuning and fix it in place as much as possible.

[0037] In this embodiment: Figure 1 As shown, the bottom end of the driving screw rod 2 is horizontally slidably mounted on a slide plate 12, which can be a sliding connection structure of a T-shaped slide groove. In addition, a horizontal rolling roller 15 is provided at the bottom of the slide plate 12. The roller 15 can be self-locking and can have its own power when necessary, or an additional external driving device can be used to drive the entire slide plate 12 to move horizontally. Figure 1 As shown, the skateboard 12 is installed under the platform 1 and can move freely under the platform 1, while the platform 1 can be installed above the ground through the support feet 13. A connecting rod (not shown in the figure) can be vertically fixed at both ends of the beam 11, and the connecting rod is vertically fixed to both sides of the skateboard 12, so as to fix the beam 11 on the front and rear sides above the skateboard 12.

[0038] In this embodiment, in order to fix the position of the sliding plate 12 after it is in place without relying on the locking of the roller 15, the sliding plate 12 can be fixed as follows: Figure 1A hydraulic telescopic column 14 is also installed at the bottom of the slide 12. When it is moved into position, the hydraulic telescopic column 14 is extended and contacts the ground to avoid the roller 15 from directly supporting the load. In addition, the support foot 13 can also have a vertical telescopic structure that can change the height of the platform 1. When necessary, the installation height of the platform 1 can be changed, and then the height position of the animal can be directly changed to better adapt to the clamping and fixing of the splint 8.

[0039] In order to more accurately and quickly perform animal trunk restraint operations, Figure 1 As shown, a slender mark rod 17 can be horizontally fixed between the left and right opposite driving screws 2, and when the corresponding driving screws 2 are close to each other, the mark rod 17 on one side can be axially slidably inserted into the mark rod 17 on the other side. The mark rod 17 is located in the center between the upper and lower clamping plates 8, which is equivalent to drawing a real center line between the two clamping plates 8. When fixing the animal, by adjusting the height of the slide plate 12 or the height of the platform 1, the center line formed by the mark rod 17 can be roughly aligned with the axial midline of the animal's trunk, thereby clamping it well to avoid serious imbalance of the trunk's unilateral restraint control force.

[0040] In the above embodiments, when the trunk of the animal is fixed or even lifted so that the entire animal is off the ground, that is, off the platform 1, if the animal's limbs are not equipped with special fixing devices, four hollow guardrail plates 16 can be installed around the surface of the platform 1 through telescopic shaft supports. The guardrail plates 16 can rise vertically to a position close to the trunk after the animal's trunk is clamped by the splints 8 from top to bottom. In this way, even if the limbs are not fixed, their range of movement is limited to the area of ​​the guardrail plates 16. As long as veterinarians and other inspection personnel do not enter the area enclosed by the guardrail plates 16, they are not easily kicked by the animal's limbs.

[0041] In the above description of the present invention, it should be noted that the terms "one side", "the other side", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0042] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
