technical field

The invention relates to the field of medical equipment, in particular to a synchronous braking device used in a medical bed.

Background technique

At present, many hospital beds in the field of medical equipment have walking mechanisms, and medical staff can use this medical bed to push patients to places that need to be moved, which brings convenience to the transfer of medical staff and patients. However, there are still some problems with existing medical beds:

First of all, the braking of these hospital beds is troublesome, and it is very inconvenient for medical staff to operate; secondly, the braking reliability of the existing medical hospital bed braking mechanism is relatively poor, and it is easy to cause unnecessary medical accidents when the braking is not firm enough; Again, the existing medical bed braking system generally only has a braking system at the head or tail of the bed, and no braking mechanism is provided at the bottom of the lower bed frame, which makes it impossible for medical staff to perform braking operations in the middle of the bed.
