[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model embodiment discloses a novel rat isolator transfer barrel.

[0029] The utility model provides Figure 1-4 A novel rat isolator transfer barrel shown in the figure comprises a transfer barrel 1 and an outer door 2 and an inner door 3 arranged on both sides of the transfer barrel 1, the outer door 2 and the inner door 3 are both made of transparent acrylic plates, the outer door 2 and the inner door 3 are both made of transparent acrylic plates, the outer door 2 and the inner door 3 are both matched with the inner wall of the transfer barrel 1, the outer walls of the outer door 2 and the inner door 3 are fixedly sleeved with a sealing ring 8, the sealing ring 8 is in contact with the inner wall of the transfer barrel 1, the outer door 2 is fixedly provided with a hinge 4 on the outside, the hinge 4 is fixedly provided with a mounting plate 5, the mounting plate 5 is screwed and fixed to the end of the transfer barrel 1 by mounting bolts 6, and a fixed device is provided between the outer door 2 and the transfer barrel 1 There are multiple clamping handle locks 7, and a clamping connection mechanism is provided on the outer side of the inner door 3. The clamping connection mechanism includes a pressure rod 10, and a pressure rod sleeve 15 is fixedly sleeved at the lower end of the pressure rod 10. Fixed hooks 11 are fixedly provided on both sides of the end of the transfer barrel 1 close to the inner door 3. A shaft rod 12 is placed in the two fixed hooks 11, and a shaft rod 12 is fixedly sleeved on the rod wall of the shaft rod 12. Two symmetrically arranged limit sleeves 14 are fixedly provided on the outer wall of the inner door 3. The limit sleeves 14 are sleeved on the outer side of the shaft rod 12, and the pressure rod 10 is fixedly connected to the outer wall of the sleeve 13. Circular baffles extending inward are provided on the sides of the inner door 3 and the outer door 2 of the transfer barrel 1.

[0030] When the transfer barrel 1 is in use, the outer door 2 can be locked with the opening of the transfer barrel 1 through a plurality of clamping handle locks 7. At the same time, the outer door 2 can be stably rotated under the support of the hinge 4 and the mounting plate 5 during the opening process. When the inner door 3 is connected with the transfer barrel 1, the shaft 12 can be placed on the two fixing hooks 11 first, and then the pressure rod 10 can be lifted up under the support of the limiting sleeve 14, so that the pressure rod 10 drives the limiting sleeve 14 to rotate during the rotation process, and the limiting sleeve 14 cooperates with the contact with the inner door 3. The connection between the shaft rod 12 and the fixed hook 11 can tightly squeeze the inner door 3. At the same time, with the connection of the two sealing rings 8, the sealing between the transfer barrel 1, the outer door 2 and the inner door 3 can be improved to prevent cross infection. The circular baffles arranged on the sides of the inner door 3 and the outer door 2 of the transfer barrel 1 are 3 cm wide. The purpose is that when transferring items, the liquid of the disinfectant spray will have residual accumulation at the bottom and will not flow out along the gap between the inner and outer doors. This can prevent corrosion to other objects, facilitate cleaning, and further improve the use effect of the transfer barrel 1.

[0031] In order to ensure the stable exchange of airflow inside the transfer barrel 1 and improve the cleanliness of the transfer barrel 1 during use, Figure 1-2 As shown, the top of the transfer barrel 1 is connected to an air intake pipe 9, and a filter screen 16 is fixedly embedded on the inner wall of the air intake pipe 9.

[0032] With the connection between the air inlet pipe 9 and the filter screen 16, the external airflow can filter the impurities inside the gas when entering the transfer barrel 1, ensuring the neatness of the airflow and cleanness of the airflow inside the transfer barrel 1.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
