DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0026] Reference Figure 1-Figure 6 , a movable ventilation device for a medical laboratory, comprising a bottom plate 1, a filter box 2 is fixedly mounted on the upper surface of the bottom plate 1, a plurality of air guide tubes 3 are symmetrically fixedly mounted above the filter box 2, and a rotating tube 4 is rotatably connected to the top of the air guide tube 3;

[0027] A mounting ring 5 is symmetrically fixedly installed on the top of the filter box 2, and the centers of the two mounting rings 5 ​​are respectively consistent with the centers of the two air guide pipes 3. A mounting plate 6 is fixedly installed on the surface of the rotating tube 4. A U-shaped clamping block 7 is horizontally slidably arranged at the bottom of the mounting plate 6. A spring rod 8 is arranged between the clamping block 7 and the mounting plate 6. The two ends of the spring rod 8 are respectively fixedly connected to the clamping block 7 and the mounting plate 6. A plurality of bayonet openings 9 for the clamping block 7 to enter are opened in a circular shape on the upper surface of the mounting ring 5;

[0028] When it is necessary to control the rotation of the rotating tube 4, first, the control block 7 is moved toward the direction close to the air guide tube 3. At this time, the spring rod 8 will shrink until the block 7 is moved out of the bayonet 9, and the lock of the rotating tube 4 can be released. Then, the rotating tube 4 is rotated until the rotating tube 4 is rotated to a suitable position. At this time, the block 7 is released, and the block 7 will quickly move and reset under the elastic potential energy of the spring rod 8, and enter the bayonet 9 corresponding to its own position, thereby completing the locking of the rotating tube 4.

[0029] A push rod 10 is vertically fixedly mounted on the upper surface of the block 7, and the surface of the push rod 10 is provided with anti-slip grooves;

[0030] The push rod 10 can be pushed toward the direction close to the air duct 3 to move with the block 7, which is convenient and quick. The anti-slip pattern can increase the friction between the push rod 10 and the contact surface of the palm.

[0031] A plurality of moving components are provided on the lower surface of the base plate 1, and the plurality of moving components are used to move the equipment. The moving components include a support rod 11 fixedly mounted on the lower surface of the base plate 1, a shell 12 and a roller 13 rotatably mounted on the bottom end of the support rod 11, a rotating shaft 14 is horizontally rotatably mounted in the shell 12, and the roller 13 is fixedly sleeved on the rotating shaft 14, so that the plurality of rollers 13 facilitate the movement of the base plate 1.

[0032] A through hole is provided on the surface of the shell 12, and the through hole is located on the rotation path of the roller 13. A locking rod 15 is slidably inserted in the through hole. A placement plate is fixedly installed at one end of the locking rod 15 located outside. A telescopic spring 16 is sleeved on the locking rod 15. The two ends of the telescopic spring 16 are respectively fixedly connected to the placement plate and the shell 12. A plurality of locking grooves 17 for inserting the end of the locking rod 15 are provided on the surface of the roller 13. A rectangular plate is fixedly installed at the bottom of the placement plate. A rotating opening is provided at the bottom end of the rectangular plate. A rotating plate 18 is rotatably installed in the rotating opening. A slot 19 for inserting the end of the rotating plate 18 is provided on the surface of the shell 12.

[0033] In the initial state, the plurality of rotating plates 18 are all in a horizontal state, and one end of the rotating plate 18 is inserted into the slot 19. At this time, the locking rod 15 is blocked by the rotating plate 18, and the end thereof located in the housing 12 does not contact the roller 13, nor is it located in the locking slot 17, so that the roller 13 can rotate at this time;

[0034] When the roller 13 moves with the device to a suitable position, the locking rod 15 can be pulled to control the end of the rotating plate 18 to move out of the slot 19. At this time, the rotating plate 18 will quickly rotate to a vertical state under the action of its own gravity, and then the locking rod 15 is released. The locking rod 15 will quickly move and reset under the elastic potential energy of the telescopic spring 16. Since the restriction imposed by the rotating plate 18 on the locking rod 15 disappears, the end of the locking rod 15 located in the housing 12 will contact the roller 13, or directly insert into the locking groove 17 corresponding to its own position. If the end of the locking rod 15 is directly inserted into the locking groove 17, the roller 13 can be locked. The roller 13 is locked. If the end of the locking rod 15 contacts the roller 13, the base plate 1 can be controlled to move, and the roller 13 will rotate. During the rotation, when a locking groove 17 rotates to correspond to the end position of the locking rod 15, the pressing force of the roller 13 on the locking rod 15 will disappear, and the locking rod 15 will quickly move and reset under the elastic potential energy of the telescopic spring 16, and the end will be inserted into the locking groove 17 corresponding to its own position, thereby completing the locking of the roller 13, and preventing the roller 13 from moving with the device when the device is working, thereby affecting the ventilation effect.

[0035] When the roller 13 needs to be unlocked, it is only necessary to pull the locking rod 15 to move its end out of the locking groove 17, and rotate the rotating plate 18 to a horizontal state, so that the end of the rotating plate 18 will correspond to the position of the slot 19, and then release the locking rod 15 to insert the end of the rotating plate 18 into the slot 19.

[0036] A spherical groove is formed at one end of the locking rod 15 located in the housing 12 . A round ball is rotatably embedded in the spherical groove. The round ball can reduce the friction between the contact surface of the locking rod 15 and the roller 13 .

[0037] In the utility model, when it is necessary to control the rotation of the rotating tube 4, first, the control block 7 is moved toward the direction close to the air guide tube 3. At this time, the spring rod 8 will shrink until the block 7 is moved out of the bayonet 9, and the locking of the rotating tube 4 can be released. Then, the rotating tube 4 is rotated until the rotating tube 4 is rotated to a suitable position. At this time, the block 7 is released again, and the block 7 will quickly move and reset under the elastic potential energy of the spring rod 8, and enter the bayonet 9 corresponding to its own position, thereby completing the locking of the rotating tube 4. After the rotating tube 4 is rotated to a suitable position, the rotating tube 4 can be quickly fixed to avoid it being rotated by the conduction force of the external or internal gas during operation, thereby changing the air intake direction.

[0038] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
