[0002] IVC is the abbreviation of individual ventilated cages, and its Chinese name is independent ventilation cage. Such an independent ventilation cage specifically refers to a feeding and experimental device that can operate and raise SPF experimental animals in a super-clean workbench by sending clean air into a closed independent unit (such as a cage box or a cage) and discharging waste gas centrally.

[0003] Currently, the IVC-type experimental animal cages in use have many pipes. To facilitate the layout and installation of the pipes, the connection of the pipes is usually completed by using a conduit joint. The existing connection methods of the joints include threaded connection, welding, and crimping, etc. In actual operation and installation, there are some problems, such as inconvenient joint manufacturing, installation, difficult loading and unloading, and slow installation speed, etc. Content of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Please refer to Figures 1-6 , the present invention provides a quick-release joint for a hose of an I VC cage, which includes:

[0041] A first joint 1, the first joint 1 is arranged on the cage, and at least one first card slot 2 is arranged on the first joint 1, and the opening of the first card slot 2 extends to the edge of the first joint 1;

[0042] A second joint 3, at least one clamping block 4 is arranged on the inner side of the second joint 3. After the first joint 1 is inserted into the second joint 3, the clamping block 4 is clamped in the first card slot 2, and one end of the second joint 3 away from the first joint 1 is connected to an outer connecting pipe 5;

[0043] A locking member 6, the locking member 6 passes through the second joint 3 and is connected to the first joint 1.

[0044] The locking member 6 is a locking screw, which is screwed into the first screw hole 7 on the second joint 3, and the locking screw passes through the first screw hole 7 and is connected to the second screw hole 8 on the first joint 1. This is convenient for operation and use, and can also improve the connection stability between the first joint and the second joint.

[0045] Two first clamping grooves 2 are provided on the first joint 1, and the two first clamping grooves 2 are arranged along the circumferential direction of the first joint 1. This can improve the connection firmness between the first joint and the second joint. The number of the first clamping grooves can also be three or four, which can be set according to the size of the first joint. If the diameter of the first joint is large, more can be set.

[0046] The first clamping groove 2 is an L-shaped clamping groove. After the second joint is installed, the clamping block and the outlet of the L-shaped clamping groove are not on the same straight line. In this way, when pulling the second joint, the L-shaped clamping groove can prevent the clamping block from disengaging from the L-shaped clamping groove, improving the connection stability of the second joint.

[0047] In one embodiment, the outer connecting pipe 5 is a telescopic hose, a spring is arranged inside the telescopic hose, at least one second clamping groove 9 is arranged on the second joint 3, and after the telescopic hose is sleeved on the second joint 3, the spring is clamped in the second clamping groove 9. This can improve the connection firmness of the telescopic hose.

[0048] A sealing cover 10 is arranged on the second joint 3, and the sealing cover 10 is screwed on one end of the second joint 3 close to the outer connecting pipe 5. The sealing cover penetrates through the telescopic hose. After the sealing cover is connected to the second joint, it can press the telescopic hose, making the telescopic hose fixed more firmly and improving the connection tightness of the telescopic hose.

[0049] In another embodiment, as Figure 6 , a plug-in groove 11 is arranged on the second joint 3, the outer connecting pipe 5 is plugged into the plug-in groove 11, and an anti-disconnection component is arranged on the surface of the second joint 3 corresponding to the plug-in groove 11. The anti-disconnection component includes a movable joint 12 and a clamping bead 13. The movable joint 12 is screwed on the second joint 3, and the clamping bead 13 is located at one end of the movable joint 12. A third clamping groove 14 is arranged on the second joint 3, the clamping bead 13 is arranged in the third clamping groove, openings are arranged on both sides of the third clamping groove 14 close to the plug-in groove 11 and the movable joint 12, and a limiting groove 15 is arranged on the groove wall of the plug-in groove 11 corresponding to the third clamping groove 14. The diameter of the opening is smaller than the diameter of the third clamping groove to prevent the clamping bead from falling off. During work, after the outer connecting pipe is inserted into the plug-in groove, rotate the movable joint, the movable joint moves towards the clamping bead direction, and presses the clamping bead through the inner wall of the movable joint, so that the clamping bead presses the outer connecting pipe and then continues to move to the limiting groove to realize the rapid fixation of the outer connecting pipe.

[0050] Working principle: The first joint is connected to the cage, and the outer connecting pipe is pre-connected to the second joint. By opening an L-shaped card slot on the first joint, when the second joint on the hose is installed, the second joint and the first joint are first inserted. After the card block is inserted into the L-shaped card slot, rotate the second joint to make the card block slide into the other end of the L-shaped card slot and lock the card block. At this time, the first screw hole and the second screw hole are aligned, and by tightening the locking screw rod, the first joint and the second joint can be fixed more stably, making the first joint and the second joint not easily fall off, with a simple structure and convenient use.

[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
