[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] See also Figure 1-5 A transport vehicle for a pharmaceutical biosafety cabinet includes a liftable hand forklift 1. The hand forklift 1 is provided with a limit mechanism 2. The limit mechanism 2 includes a fixed block 21 fixed to the hand forklift 1. A limit frame 22 is slidably provided on the fixed block 21. A side plate 23 is provided on the side of the fixed block 21 away from the limit frame 22. The limit frame 22 and the side plate 23 respectively abut against two sides of the safety cabinet to secure the safety cabinet. The vehicle also includes a locking assembly 3 for locking the limit frame 22. The liftable hand forklift 1 is a general production equipment and will not be described in detail.

[0026] Place the safety cabinet on the fixed block 21 on the hand forklift 1, and raise the hand forklift 1 to lift the safety cabinet, move the limit frame 22, so that the limit frame 22 and the side plate 23 are respectively in contact with the two sides of the safety cabinet, and lock the position of the limit frame 22 by the locking assembly 3, so as to limit the position of the safety cabinet and prevent the safety cabinet from slipping and being damaged during the movement of the hand forklift 1, thereby eliminating safety hazards.

[0027] Furthermore, the locking assembly 3 includes a one-way tooth 31 fixedly mounted on the limit frame 22. A locking rod 32 is rotatably connected to the fixed block 21. A torsion spring 33 is fixedly connected between the locking rod 32 and the fixed block 21. A latching rod 34 is also provided in the fixed block 21 for limiting the rotation range of the locking rod 32. When the latching rod 34 is limited, the locking rod 32 can limit the movement of the limit frame 22 in the direction of the limit frame 22. The one-way tooth 31 includes a plurality of latching teeth 311 connected end to end, with locking grooves 312 formed between adjacent latching teeth 311. The latching teeth 311 are arranged in a triangular shape, with the inclined surface of the triangle facing one side of the side plate 23. The latching rod 34 is slidably connected to the fixed block 21. The triangle is preferably a right triangle or an obtuse triangle.

[0028] When the limit frame 22 moves toward the side panel 23, the limit frame 22 drives the one-way tooth 31 to move. The locking rod 32 extending into the locking groove 312 rotates under the drive of the inclined surface of the latch tooth 311 and resets under the action of the retaining spring. When the limit frame 22 moves away from the side panel 23, the side of the latch tooth 311 drives the locking rod 32 to rotate in the opposite direction. However, because the latch rod 34 restricts the reverse rotation of the locking rod 32, the limit frame 22 cannot move away from the side panel 23, thereby completing the locking of the limit frame 22. That is, the locking assembly 3 enables the limit frame 22 to move unidirectionally toward the side panel 23, and when the limit frame 22 abuts against the safe, the position of the limit frame 22 is passively locked, thereby automatically securing the safe. The latch rod 34 is withdrawn from the fixing block 21, and the limit frame 22 can be moved away from the side panel 23, thereby adapting to safes of different sizes. It is worth noting that the locking stability can be improved by adding a plurality of matching locking rods 32, clamping rods 34 and torsion springs 33.

[0029] Furthermore, the device further includes a shock-absorbing assembly 4, which includes a first slide bar 41 and a second slide bar slidably mounted on the side plate 23 and the limiting frame 22, respectively. The first slide bar 41 has a first shock-absorbing block 42 and a first baffle 43 fixedly connected at both ends, respectively. The second slide bar has a second shock-absorbing block and a second baffle fixedly connected at both ends. The first baffle 43 is slidably connected to the side plate 23, and the second baffle is slidably connected to the limiting frame 22. A first spring 44 is disposed between the first baffle 43 and the side plate 23, and a second spring is disposed between the second baffle and the side plate 23. Rubber pads are disposed on the outer surfaces of the first and second shock-absorbing blocks 42 and 43.

[0030] The rubber pad, the first spring 44 and the second spring can reduce the shock of the safety cabinet, so as to reduce the impact of the vibration generated by the hand forklift 1 during transportation on the safety cabinet.

[0031] Working principle: Place the safety cabinet on the fixed block 21 on the hand forklift 1, and raise the hand forklift 1 to lift the safety cabinet, move the limit frame 22 toward the side panel 23, so that the limit frame 22 and the side panel 23 are respectively in contact with the two sides of the safety cabinet, and the locking component 3 automatically locks the position of the limit frame 22, thereby limiting the position of the safety cabinet to prevent the safety cabinet from slipping and being damaged during the movement of the hand forklift 1, and reduces the impact of the vibration generated by the hand forklift 1 during transportation on the safety cabinet through the shock-absorbing component 4.

[0032] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
