Description

Technical Field

[0001] This utility model relates to the field of cages, specifically to an experimental monkey cage with an anti-opening lock. Background Technology

[0002] In certain specialized industries, monkeys are required for experiments. For example, in the biopharmaceutical industry, developing a new drug or reagent often begins with monkey testing. Monkeys are typically kept in cages during both experimental and non-experimental phases. However, monkeys are more intelligent than other animals, and they observe and learn how to open the cages repeatedly. Given the extremely high probability that monkeys can open existing cages, this can range from disrupting the experimental process to posing a significant threat to the safety of the laboratory and its personnel. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an experimental monkey cage with an anti-opening lock.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: It includes a cage, a small monkey cage door, an anti-opening lock mechanism, and a feed box. The small monkey cage door is movably installed on the cage. A portion of the anti-opening lock mechanism is installed on the small monkey cage door, and another portion is installed on the cage. The anti-opening lock mechanism is used to open or lock the small monkey cage door. The anti-opening lock mechanism includes a first lock member, a second lock member, a fixing pin, and a first lever. The fixing pin is fixedly installed on the second lock member. When the first lock member and the second lock member are inserted together, the anti-opening lock mechanism is locked, and the small monkey cage door is in a locked state. When the first lever is moved, the first lever moves the fixing pin, thereby causing the first lever to move the second lock member. The second lock member separates from the first lock member, the anti-opening lock mechanism unlocks, and the small monkey cage door is in an unlocked state.

[0005] Furthermore, the first lock member has a locking groove, and the second lock member includes a locking head. When the second lock member is inserted into the first lock member, the locking head of the second lock member is inserted into the locking groove, thereby fixing the first lock member and the second lock member together, thus making the anti-opening lock mechanism in a locked state; when the locking head of the second lock member leaves the locking groove of the first lock member, the anti-opening lock mechanism is in an unlocked state.

[0006] Furthermore, the anti-opening lock mechanism also includes a compression spring, and the second lock member also includes a second lock member body. The second lock member body and the locking head are fixedly connected together. The compression spring and the second lock member body are fixedly connected together. Under the elastic force of the compression spring, the second lock member body moves, and the second lock member body drives the locking head to move. The locking head is inserted into the locking groove of the first lock member, thereby locking the anti-opening lock mechanism. The first lever drives the fixing pin to move, thereby moving the second lock member. During the movement, the second lock member compresses the compression spring, giving the compression spring elastic force. At this time, the anti-opening lock mechanism is unlocked.

[0007] Furthermore, the anti-opening lock mechanism also includes a mounting cylinder, which has an installation space and an opening, the opening and the installation space being in communication. The mounting cylinder has a bottom wall, which forms part of the installation space. The second locking member is movably installed in the installation space of the mounting cylinder. The compression spring is placed in the installation space of the mounting cylinder, with one end of the compression spring abutting against the body of the second locking member and the other end abutting against the bottom wall of the mounting cylinder. When the compression spring is compressed, at least a portion of the second locking member retracts into the installation space of the mounting cylinder. When the compression spring releases its elastic force, at least a portion of the second locking member extends out of the installation space of the mounting cylinder.

[0008] Furthermore, the fixing pin is fixedly installed on the locking head of the second lock member, and the fixing pin and the locking head of the second lock member are perpendicular; the first lever pivots to drive the fixing pin to move, and the fixing pin drives the locking head of the second lock member to move, so that the locking head is at least partially retracted into the mounting cylinder, the compression spring is compressed, and the compression spring has elastic force. At this time, the anti-opening door lock mechanism is opened; when the first lever is released, under the action of the elastic force of the compression spring, the locking head of the second lock member at least partially extends out of the mounting space of the mounting cylinder, and the locking head of the second lock member is inserted into the locking groove of the first lock member. At this time, the anti-opening door lock mechanism is locked.

[0009] Furthermore, the anti-opening lock mechanism also includes a second lever, which is fixedly connected to the first lever and is perpendicular to the first lever. The second lever is provided with hexagonal bolt holes.

[0010] Furthermore, the first locking member is also provided with a first guide surface, which is disposed in the locking groove and constitutes a part of the locking groove; the second locking member is provided with a second guide surface, which is disposed on the locking head of the second locking member and constitutes a part of the locking head; the first guide surface of the first locking member and the second guide surface of the second locking member are adapted to each other, so as to make the insertion or separation of the first locking member and the second locking member smoother.

[0011] Furthermore, the first guide surface of the first locking member is an inclined surface, and the second guide surface of the second locking member is an inclined surface.

[0012] Furthermore, it also includes a feed box, which is welded to the small door of the monkey cage. The feed box includes a feed box body and a cover, which are fixedly connected by bolts. The feed box body has an installation space and a second installation through hole, which passes through the feed box body and communicates with the installation space. The cover has a first installation through hole, which passes through the cover. The anti-opening lock mechanism is installed in the installation space, and the second lever is inserted into the second installation through hole, and the second lever can be inserted into the second installation through hole. The feed box rotates; when the cover blocks the feed box body, at least a portion of the second lever extends out of the first mounting through hole on the cover; the first locking member is fixedly installed on the small door of the monkey cage by welding, and the small door of the monkey cage moves up and down to open or close the monkey cage; the feed box is also provided with a through hole, the through hole passes through the feed box body of the feed box, and the through hole communicates with the mounting space; when the small door of the monkey cage descends, it drives the first locking member to pass through the through hole and enter the mounting space of the feed box body, thereby locking the small door of the monkey cage on the cage box by the cooperation of the first locking member and the second locking member.

[0013] Furthermore, the feed box also includes a sleeve, which is fixedly installed on the feed box body and located in the installation space of the feed box body. The sleeve has a connecting through hole that axially extends through the sleeve, and the connecting through hole of the sleeve is aligned with and communicates with a second mounting through hole on the feed box body. At least a portion of the second lever extends into the connecting through hole of the sleeve, and the second lever is rotatable in the connecting through hole. The feed box body is welded to the small door of the monkey cage.

[0014] The beneficial effects of this application are as follows: The experimental monkey cage with anti-opening lock provided by this application has a simple structure and is easy to assemble and disassemble. The first lever is pivoted by the second lever, the first lever moves the fixing pin, and the fixing pin moves the second locking member, thereby separating the first locking member and the second locking member and opening the monkey cage. Under the elastic force of the compression spring, the second locking member is pushed and inserted into the first locking member, locking the monkey cage. The monkey cage provided by this application requires a special tool to rotate the second lever, and the first lever and the second lever form a lever with a high effort requirement, which makes it extremely difficult for a monkey placed in the cage to open, and the security is extremely high.

[0023] Please refer to Figure 1-5 This application provides a laboratory monkey cage with an anti-opening lock (hereinafter referred to as "the monkey cage"). The monkey cage includes a cage box 4, a small monkey cage door 1, an anti-opening lock mechanism 2, and a feed box 3. The small monkey cage door 1 is movably mounted on the cage box 4. A portion of the anti-opening lock mechanism 2 is mounted on the small monkey cage door 1, and a portion of the anti-opening lock mechanism 2 is mounted on the cage box 4. The anti-opening lock mechanism 2 is used to open or lock the small monkey cage door 1. The anti-opening lock mechanism 2 includes a first locking member 21, a second locking member 24, a fixing pin 25, and a first lever 26. The fixing pin 25 is fixedly installed on the second locking member 24. When the first locking member 21 and the second locking member 24 are inserted together, the anti-opening door lock mechanism 2 is locked, and the monkey cage door 1 is in a locked state. When the first lever 26 is moved, the first lever 26 moves the fixing pin 25 during the movement, thereby causing the first lever 26 to move the second locking member 24. The second locking member 24 is separated from the first locking member 21, the anti-opening door lock mechanism 2 is unlocked, and the monkey cage door 1 is in an unlocked state.

[0024] In one embodiment of this application, the first lock member 21 is provided with a locking groove 210, and the second lock member 24 includes a locking head 242. When the second lock member 24 is inserted into the first lock member 21, the locking head 242 of the second lock member 24 is inserted into the locking groove 210, thereby fixing the first lock member 21 and the second lock member 24 together, thereby making the anti-opening door lock mechanism 2 in a locked state; when the locking head 242 of the second lock member 24 leaves the locking groove 210 of the first lock member 21, the anti-opening door lock mechanism 2 is in an unlocked state.

[0025] In one embodiment of this application, the anti-opening lock mechanism 2 further includes a compression spring 23, and the second lock member 24 further includes a second lock member body 241. The second lock member body 241 and the locking head 242 are fixedly connected together. The compression spring 23 and the second lock member body 241 are fixedly connected together. Under the elastic force of the compression spring 23, the second lock member body 241 moves, and the second lock member body 241 drives the locking head 242 to move. The locking head 242 is inserted into the locking groove 210 of the first lock member 21, thereby locking the anti-opening lock mechanism 2. The first lever 26 drives the fixing pin 25 to move, thereby moving the second lock member 24.

The anti-opening door lock mechanism 2 is installed in the installation space 320, and the second lever 27 is inserted into the second installation through hole 321. The second lever 27 can be inserted into the second installation through hole. The second lever 27 rotates in the first mounting through hole 310 on the cover 31 when the cover 31 blocks the feed box body 32. The first locking member 21 is fixedly installed on the monkey cage door 1 by welding. The monkey cage door 1 moves up and down to open or close the monkey cage. The feed box 3 is also provided with a through hole 321, which passes through the feed box body 32 of the feed box 3 and is connected to the mounting space 320. When the monkey cage door 1 descends, it drives the first locking member 21 through the through hole 321 into the mounting space 320 of the feed box body 32.

The feed box body 32 is welded to the monkey cage door 1.

[0033] The experimental monkey cage with anti-opening lock provided in this application has a simple structure and is easy to assemble and disassemble. A second lever drives a first lever to pivot, which in turn moves a fixing pin. The fixing pin then moves a second locking component, thus separating the first and second locking components and opening the cage. Under the elastic force of a compression spring, the second locking component is pushed and inserted into the first locking component, locking the cage. This monkey cage requires a special tool to rotate the second lever, and the first and second levers form a lever requiring considerable effort, making it extremely difficult for a monkey placed inside to open, thus ensuring high security.
