Abstract
Description
Technical Field
[0001] This utility model relates to a locking device to prevent wild animals from climbing and escaping, and belongs to the field of animal protection and engineering design. Background Technology
[0002] The design of animal enclosures in zoos usually needs to take into account factors such as animal welfare, visitor viewing, and safety. For giant pandas and other primates, which typically have strong climbing abilities, preventing escape becomes an important issue under captive conditions.
[0003] On the one hand, due to design flaws in the fence (such as insufficient height or lack of anti-climbing structures) or too many leverage points such as surrounding trees and rocks, physical isolation is still the most effective way to prevent escape, while the electric fence can only serve as an auxiliary device.
[0004] On the other hand, the height of walls, glass, railings, etc., is an important factor in animal control, but due to limitations such as space and viewing conditions, traps are usually installed at the top. However, typical traps are fixed to the top of walls or railings to prevent animals from extending their forearms to grab the top and flip over. Summary of the Invention
[0005] To address the aforementioned problems, the purpose of this utility model is to provide a reverse-locking device that prevents wild animals from climbing and escaping. Designed using the seesaw principle, it can effectively prevent wild animals from climbing and escaping.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A locking device to prevent wild animals from climbing and escaping includes:
[0008] Several support rods are arranged side by side. One end of each support rod is fixed to the outer wall or railing, and the other end is hinged to a buckle plate through a buckle support point, so that the buckle plate can move up and down around the buckle support point.
[0009] The reverse buckle plate is longer than the support rod, and one end is the near-wall end, which is attached to the top of the outer wall or a protrusion on the top of the wall. The end is provided with a retainer to make the reverse buckle plate and the support rod form a preset angle; the other end is the far-wall end to prevent wild animals from climbing.
[0010] Furthermore, the spacing between each of the support rods is greater than 1.2m.
[0011] Furthermore, the length of each of the aforementioned support rods shall not exceed 20cm.
[0012] Furthermore, the retainer is a counterweight disposed on the upper part of the buckle plate or an elastic element disposed on the top of the wall or a protrusion on the top of the wall to provide upward support.
[0013] Furthermore, the weight of the counterweight should be such that the buckling device maintains its normal shape.
[0014] Furthermore, the angle of inclination formed between the near-wall end of the inverted plate and the support rod is an acute angle, with an angle range of 75 to 80°.
[0015] Furthermore, the end face of the reverse buckle plate at the far wall end is set to an arc shape.
[0016] Furthermore, the reverse buckle is made of a rigid material.
[0017] Furthermore, the reverse buckle support point adopts a sleeve or bearing structure, which allows the reverse buckle plate to move smoothly up and down around the reverse buckle support point.
[0018] Furthermore, the reverse buckle support point adopts a movable reverse buckle.
[0019] This utility model has the following advantages due to the adoption of the above technical solution:
[0020] 1. In this utility model, the support rod and the buckle plate are designed based on gravity and inertia, which is different from the existing fixed bracket type buckle, and the structure is simple.
[0021] 2. This utility model can be spliced and assembled, and its parts can be replaced, making it easy to install and maintain.
[0022] 3. The support rod provided by this utility model uses a bearing to connect the reverse buckle plate, maintaining a sensitive response.
[0023] 4. The far end of the reverse buckle plate of this utility model is designed as a smooth arc, so that wild animals have no point of leverage when climbing.
[0024] Therefore, this utility model has a wide range of applications, applicable to giant pandas, primates, or cats and canines with strong jumping abilities, and can be widely used in animal protection and engineering design fields. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0029] In some embodiments of this utility model, a buckle device is provided to prevent wild animals from climbing and escaping. This device is made using the seesaw principle and can effectively prevent wild animals from climbing and escaping.
[0030] Example 1
[0031] like Figure 1 As shown, the present invention provides a reverse-locking device to prevent wild animals from climbing and escaping. It includes several support rods 1 arranged side by side. One end of each support rod 1 is fixedly mounted on the outer wall or railing 2, and the other end is hinged to a reverse-locking plate 4 through a reverse-locking support point 3, so that the reverse-locking plate 4 can move up and down around the reverse-locking support point 3. The length of the reverse-locking plate 4 is greater than that of the support rod 1, and one end of the reverse-locking plate 4 is the near-wall end, which is placed on the top of the outer wall or a protrusion 5 set on the top of the wall. The end is provided with a retainer to make the reverse-locking plate 4 and the support rod 1 form a preset angle. The other end of the reverse-locking plate 4 is the far-wall end to prevent wild animals from climbing.
[0032] Furthermore, the spacing between each support rod 1 should be greater than 1.2m, preferably exceeding the combined arm span of an adult wild animal.
[0033] Furthermore, the length of each support rod 1 shall not exceed 20cm to ensure that the body of an adult wild animal cannot pass through smoothly.
[0034] Furthermore, the retainer provided near the wall end of the reverse buckle plate 4 can be an elastic element that provides upward support force to the counterweight 6 provided on the upper part of the reverse buckle plate 4 or the protrusion 5 provided on the top of the wall or the top of the wall.
[0035] Furthermore, the weight of the counterweight 6 should be sufficient to keep the buckle device in its normal position. Once the force on the far end of the buckle plate 4 exceeds the counterweight, the buckle device will immediately flip over to prevent wild animals from climbing and escaping.
[0036] Furthermore, the angle of inversion formed between the near-wall end of the inverted plate 4 and the support rod 1 is an acute angle, ranging from 75 to 80°, to increase the probability of the inverted device flipping over after the far-wall end is subjected to force.
[0037] Furthermore, the end face of the far wall end of the reverse buckle 4 is set to be arc-shaped to ensure that wild animals have no point of force when they touch the reverse buckle.
[0038] Furthermore, the reverse buckle 4 is made of rigid material.
[0039] Furthermore, the reverse buckle support point 3 adopts a sleeve or bearing structure, which allows the reverse buckle plate 4 to move smoothly up and down around the reverse buckle support point 3.
[0040] Furthermore, the reverse buckle support point 3 adopts an active reverse buckle.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
