一种具有防晃动功能的细胞冻存装置

Abstract

本实用新型公开了一种具有防晃动功能的细胞冻存装置，包括细胞冻存箱、推车和刹车装置，细胞冻存箱固定放置在推车上，用于推车后轮制动的刹车装置设置在推车上，刹车装置包括控制组件、锁定组件和刹车线，控制组件设置在推车中扶手处，锁定组件设置在推车上的后轮处，锁定组件和控制组件通过刹车线连接，锁定组件自动锁止后轮，控制组件一键解除锁定组件对推车的锁止。优点，当设备放置在倾斜地面上时，通过锁定组件可以自动锁止推车后轮，防止设备发生溜道导致晃动和磕碰，进一步避免保管的细胞震荡从而损坏，通过控制组件可以一键解除锁定组件对推车后轮的锁止以此能够进行设备的转运，锁止和解锁更加方便，有效提高了装置的便利性和适用性。

Claims

1. A cell cryopreservation device with anti-shaking function, comprising a cell cryopreservation box (1), characterized in that: It also includes a trolley (2) and a braking device (3). The cell cryopreservation box (1) is fixedly placed on the trolley (2), and the braking device (3) for braking the rear wheels of the trolley (2) is set on the trolley (2). The braking device (3) includes a control component (31), a locking component (32) and a brake cable (33). The control component (31) is located at the handle (21) in the trolley (2), and the locking component (32) is located at the rear wheel on the trolley (2). The locking component (32) and the control component (31) are connected by the brake cable (33). The locking component (32) automatically locks the rear wheel, and the control component (31) releases the locking component (32) from locking the trolley with one key.

2. The cell cryopreservation device with anti-shaking function according to claim 1, characterized in that: The control component (31) includes a locking button (311), an unlocking wristband (312), and a locking assembly (313). The locking assembly (313) is located inside the armrest (21) and is detachable. The unlocking wristband (312) is fitted onto the surface of the armrest (21). Pulling the unlocking wristband (312) engages the locking assembly (313). The locking button (311) is located on the armrest (21). Pressing the locking button (311) releases the engagement of the locking assembly (313).

3. The cell cryopreservation device with anti-shaking function according to claim 2, characterized in that: The unlocking wristband (312) is connected to the locking component (32) via the brake cable (33). Pulling the unlocking wristband (312) releases the automatic locking of the rear wheel by the locking component (32).

4. The cell cryopreservation device with anti-shaking function according to claim 2, characterized in that: The locking assembly (313) includes a first buckle (314) and a second buckle (315). The first buckle (314) is located inside the armrest (21) and connected to the locking button (311). The second buckle is located inside the armrest (21) and connected to the unlocking wristband (312). Pulling the unlocking wristband (312) causes the second buckle (315) to engage with the first buckle (314). Pressing the locking button (311) releases the engagement between the second buckle (315) and the first buckle (314).

5. The cell freezing device with anti-shaking function according to claim 1, characterized in that: The locking assembly (32) includes a first brake arm (321), a second brake arm (322), and a brake pin (324). The first brake arm (321) and the second brake arm (322) are hinged together. A brake cable (33) is located at one end of the first brake arm (321) and the second brake arm (322). The brake pin (324) is located at the other end of the first brake arm (321) and the second brake arm (322). The brake pin (324) is in movable engagement with the rear wheel. Pulling the brake cable (33) causes the first brake arm (321) and the second brake arm (322) to rotate and unfold along the hinge, thereby releasing the engagement between the brake pin (324) and the rear wheel.

6. The cell cryopreservation device with anti-shaking function according to claim 5, characterized in that: A torsion spring (323) is provided at the hinge of the first brake arm (321) and the second brake arm (322). The first brake arm (321) and the second brake arm (322) are contracted under the action of the torsion spring (323) to keep the brake pin (324) in contact with the rear wheel.

7. The cell freezing device with anti-shaking function according to claim 5, characterized in that: A locking hole is provided on the rear wheel to cooperate with the brake pin (324). 8.The cell cryopreservation device with anti-shaking function of claim 1, wherein: An installation opening is provided on the surface of the handrail (21). 9.The cell cryopreservation device with anti-shaking function of claim 1, wherein: The front wheels of the trolley (2) are swivel wheels.
