Description
Technical Field
[0001] This utility model relates to the field of laboratory animal equipment technology, and in particular to a novel isolator for mouse breeding. Background Technology
[0002] Mouse breeding, especially in SPF (Specific Pathogen Free) environments, requires extremely high levels of cleanliness and isolation. Isolators are key equipment for maintaining such sterile or highly clean environments and must be able to completely isolate the animals inside from the external environment to prevent the entry of any microorganisms or contaminants.
[0003] Existing isolators are large and heavy. To ensure stability during use, they are placed on fixed support legs. However, this makes it very inconvenient to move the isolators when the position needs to be adjusted or the ground needs to be cleaned. Other isolators equipped with wheels are easy to move, but they will wobble due to uneven ground or accidental contact during daily use, lacking sufficient stability.
[0004] In addition, the isolator needs to deliver items to the inside through a transfer mechanism. The existing transfer mechanism is inadequate in terms of sealing and locking. The locking structure of the isolator's sealing door is often relatively simple, and after frequent use, the sealing may not be tight. The coordination between the isolator's disinfection device and the transfer channel is not optimized enough, making it difficult to ensure that items are thoroughly disinfected during the transfer process. This poses a risk to maintaining a sterile environment inside the isolator.
[0005] Therefore, this invention proposes a novel isolator for mouse breeding to address the shortcomings of existing technologies. Utility Model Content
[0006] In view of the problems of inconvenience in movement and poor stability of existing mouse breeding isolators, as well as unreliable sealing and locking during item transfer and the resulting contamination, this utility model aims to provide a novel mouse breeding isolator with an improved structure that can effectively solve the above problems.
[0007] This utility model provides a novel isolator for mouse breeding, comprising: a main body 1, and a main body 2 stacked on top of the main body 1; an auxiliary mechanism disposed at the bottom of the main body 1, and a transmission mechanism disposed at the rear side of the main body 1 and the main body 2.
[0008] The auxiliary mechanism includes a support foot encircling the bottom of the main body, a telescopic rod for driving the support foot to rise and fall, and wheels located on the bottom surface of the main body.
[0009] The transmission mechanism includes a pipe extending from the rear side of the first body and the second body. A nozzle is provided inside the pipe. The end of the pipe near the main body is rotatably connected to the first body and the second body via a cylinder and a door panel. The open end of the pipe is hinged to a circular plate via a hinge.
[0010] Furthermore, the circular plate is provided with a handle, and the handle is fixedly connected to a long column and a short column. A circular tube is fixed on the pipe, and a hook plate is provided inside the circular tube. The long column and the short column pass through the circular tube, and the short column is used to detachably engage with the groove of the hook plate to lock the circular plate.
[0011] Preferably, a sealing strip is provided between the joint of the first body and the second body.
[0012] Preferably, the support legs of the auxiliary mechanism are adjustablely connected to the bottom perimeter of the main body via the telescopic rod.
[0013] Preferably, the two ends of the cylinder of the transmission mechanism are respectively embedded in the grooves opened in the first body and the second body for the cylinder, so that the door panel can rotate around the axis of the cylinder.
[0014] Preferably, the circular plate of the transmission mechanism is rotatably connected to the front end of the pipe via the hinge.
[0015] Preferably, a spring is fitted onto the long column of the transmission mechanism.
[0016] Preferably, the handle of the transmission mechanism can rotate around its own axis to drive the short column into or out of the slot of the hook plate.
[0017] Preferably, the hook plate of the transmission mechanism is fixed to the inner wall of the circular tube.
[0018] This utility model has the following beneficial effects: 1. This utility model solves the problems of existing isolators that are either bulky and difficult to move, or have unstable support due to the moving device, by setting an auxiliary mechanism at the bottom of the main body. The auxiliary mechanism includes a support foot, a telescopic rod and wheels. The telescopic rod controls the raising and lowering of the support foot to switch between the support foot and the wheel on the ground. This achieves the effect of flexibly switching between ensuring stable support during operation and convenient movement when needed.
[0019] 2. This utility model solves the problems of unreliable sealing and locking of existing transfer devices and pollution caused by setting a transfer mechanism on the rear side of the main body. The transfer mechanism includes a pipe with a nozzle, an inner door panel and an outer circular plate. The circular plate is locked by a locking mechanism composed of a handle, a long column, a short column, a spring and a hook plate. This achieves the effect of unique structure, reliable locking, easy disinfection and safe transfer of items. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages 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 a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Example: Please refer to Figure 1 and Figure 4As shown, a novel isolator for mouse breeding includes a main body 1 serving as a support base, and a second main body 2 stacked on top of the main body 1. The main bodies 1 and 2 constitute the main accommodating space of the isolator. A sealing strip 44 is provided between the joint of the main bodies 1 and 2 to fill the gap between the two bodies and prevent external bacteria from entering. The overall structure of the isolator also includes an auxiliary mechanism 4 for stable support and convenient movement, and a transfer mechanism 3 for the transfer and disinfection of sterile items. The auxiliary mechanism 4 is integrally located at the bottom of the main body 1, while the transfer mechanism 3 is installed and fixed on the rear sidewalls of the main bodies 1 and 2. Mechanism 4 includes multiple support feet 41 arranged around the bottom of the main body 1. Each support foot 41 is connected to the main body 1 via a telescopic rod 42. Multiple wheels 43 are also provided on the bottom surface of the main body 1. When it is necessary to place the isolator stably, the telescopic rod 42 is extended to support the support foot 41 on the ground. When it is necessary to move the isolator, the telescopic rod 42 is retracted to lift the support foot 41 off the ground, so that the wheels 43 can contact the ground. The main structure of the transmission mechanism 3 is a pipe 31 extending from the rear wall of the isolator. The pipe 31 forms a transition channel. The inside of the channel is equipped with nozzles 36 for spraying disinfectant. The two ends of the channel are closed by door panels 32 and circular plates 34, respectively.
[0024] Please refer to Figure 1 , Figure 2 and Figure 3The pipe 31 of the transmission mechanism 3 has a door panel 32 near one end of the main body. The door panel 32 is pivotally connected to the main body 1 and the main body 2 via a central cylinder 33. Specifically, the main body 1 and the main body 2 have corresponding slots, and the two ends of the cylinder 33 are respectively embedded in the two slots, so that the door panel 32 can rotate and open around the axis of the cylinder 33. The open end of the pipe 31 of the transmission mechanism 3 is hinged to a circular plate 34 via a hinge 35. The circular plate 34 can be flipped open or closed under the action of the hinge 35 to seal the opening of the pipe 31. In order to lock the circular plate 34, a handle 37 is installed on the circular plate 34. The handle 37 is fixedly connected to a long column 39 and a short column 310. A circular tube 38 is fixedly installed on the outer wall of the pipe 31. A hook plate 311 is fixed to the inner wall of the circular tube 38. The hook plate 311 has a... During assembly, the long column 39 and the short column 310 pass through the round tube 38, and a spring is fitted on the long column 39. When it is necessary to close the round plate 34, pull the handle 37. The handle 37 moves the long column 39 and the short column 310 together. The long column 39 will compress the spring fitted on the long column 39. At this time, rotate the handle 37. Since the handle 37 can rotate around its own axis, the rotation allows the short column 310 to be inserted into the slot of the hook plate 311. After releasing the handle 37, the spring returns to its original position and pushes the long column 39, thereby making the short column 310 tightly engaged with the slot of the hook plate 311, thus firmly locking the round plate 34. When it is necessary to open the round plate 34, pull the handle 37 again to overcome the spring force and rotate the handle 37 in the opposite direction, so that the short column 310 disengages from the slot of the hook plate 311. At this time, the round plate 34 can be flipped open by the hinge 35.
[0025] like Figure 1 As shown, to enhance the sealing performance when the main body 1 and the main body 2 are stacked together, a sealing strip 44 is provided at the joint between the upper edge of the main body 1 and the lower edge of the main body 2. Please refer to... Figure 1 and Figure 4 The support feet 41 of the auxiliary mechanism 4 are arranged around and adjustablely connected to the bottom of the main body 1. Each support foot 41 is connected to the bottom surface of the main body 1 via a corresponding telescopic rod 42. Please refer to... Figure 1 The installation structure of the door panel 32 in the transmission mechanism 3 is as follows: Grooves are respectively formed on the main body 1 and the main body 2 at the two ends of the cylinder 33 to accommodate the ends of the cylinder 33. The two ends of the cylinder 33 are respectively embedded in the corresponding grooves, thereby enabling the door panel 32 to rotate around the axis of the cylinder 33. Please refer to... Figure 2 and Figure 3 In the transmission mechanism 3, the circular plate 34 is rotatably connected to the edge of the front opening of the pipe 31 via a hinge 35. To achieve locking, a spring is fitted onto the long column 39. When the handle 37 is pulled, the handle 37 moves the long column 39, thereby compressing the spring fitted onto the long column 39. Please refer to... Figure 2The handle 37 is also designed to rotate around its own axis to drive the fixedly connected short column 310 to rotate, so that the short column 310 can be engaged or disengaged from the slot on the hook plate 311. In order to provide a stable locking point, the hook plate 311 is fixed to the inner wall of the round tube 38, and the round tube 38 is fixedly installed on the outer wall of the pipe 31.
[0026] Working principle: When the isolator needs to be moved, the operator controls the auxiliary mechanism 4 and operates the telescopic rod 42 to retract it. The retraction of the telescopic rod 42 pulls the adjustable support foot 41, which is connected to the bottom of the main body 1, upwards until the support foot 41 is completely off the ground. At this point, the wheel 43 on the bottom of the main body 1 contacts the ground, allowing the operator to push the isolator for easy movement. Once the isolator is moved to the predetermined working position, the operator reverses the telescopic rod 42 to extend it. The extension of the telescopic rod 42 pushes the support foot 41 downwards until it firmly contacts the ground, thus moving the main body... The isolator 1, together with the main body 2 stacked on top, is stably supported. At this time, the wheels 43 are preferably suspended or unloaded, ensuring the stability of the isolator during the breeding or experimental process. Throughout the use, the sealing strip 44 set at the joint of the main body 1 and the main body 2 continuously provides a sealing effect, preventing external contaminants from entering the isolator through the joint gap. When it is necessary to transfer items into the isolator, the operator first operates the transfer mechanism 3. The operator holds and pulls the handle 37 installed on the circular plate 34. Since the handle 37 is fixedly connected to the long column 39 and the short column 310, the action of pulling the handle 37 will cause the long column 39 to compress the spring sleeve on the long column 39. The spring simultaneously drives the short column 310 to move inside the circular tube 38 fixed to the pipe 31. At this time, the operator turns the handle 37, which can rotate around its own axis, causing the short column 310 to rotate synchronously, so that the short column 310 disengages from the slot of the hook plate 311 fixed to the inner wall of the circular tube 38. The circular plate 34 is then unlocked, and the operator can flip it open by hinge 35 to expose the opening of the pipe 31. After placing the items inside the pipe 31, the circular plate 34 is closed, and the nozzle 36 inside the pipe 31 is activated to spray disinfection on the space inside the pipe 31 and the items inside. After disinfection is completed, the personnel or users inside the isolator can disengage. The door panel 32 is pushed open by rotating around the cylinder 33, which serves as a pivot. The disinfected items are then taken into the main body 1 or the main body 2. After the items are taken out, the door panel 32 can be automatically or manually reset and closed. After the transfer is completed, the external operator needs to lock the circular plate 34. The operator pulls the handle 37 to compress the spring again and rotates the handle 37 so that the short column 310 is aligned with the groove of the hook plate 311. The operator releases the handle 37, the spring returns to its original position, and the spring force pushes the long column 39 and pulls the short column 310 in the opposite direction, so that the short column 310 is firmly locked into the groove of the hook plate 311, thereby achieving reliable locking of the circular plate 34 and ensuring the sealing of the transfer mechanism 3.
