Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a convalescent bed with a pedal brake. Background Art

[0002] The brakes of existing nursing beds are all set on the rollers and are independent of each other. Generally, only one of the rollers needs to be limited to fix the entire nursing bed. However, this braking method is very unstable in actual use. Since the other rollers are not fixed, the entire nursing bed will still shake. However, if stability is to be guaranteed, the brakes on each roller must be fixed separately, which is very troublesome. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a convalescent bed with a foot brake which is easy to use and more stable after braking.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a convalescent bed with a foot-operated brake, comprising a bed body, four rollers being arranged at the lower part of the bed body, brake mechanisms being arranged at the rollers, a linkage mechanism being arranged between the brake mechanisms at both ends of the bed body, the brake comprising a brake pedal, a brake rod and a locking pressure block, the brake pedal being mounted at the end of the brake rod, the brake rod being inserted into the locking pressure block and being able to press the locking pressure block downward when rotating, the locking pressure block being able to abut against the roller when pressed downward, the two brake mechanisms at the lower part of one end of the bed body sharing a brake rod, the linkage mechanism comprising a linkage rod and a transmission block, and both ends of the linkage rod being transmission-connected to the brake rod on the corresponding side through the transmission block.

[0005] In the above technical solution, the brake rod is a hexagonal rod.

[0006] In the above technical solution, two ends of the brake pedal are provided with treading planes, and different marks are provided on the two treading planes.

[0007] In the above technical solution, one end of the transmission block is fixedly connected to the brake rod, and the other end is mounted on the end of the linkage rod through a bolt.

[0008] In the above technical solution, a sleeve is installed in the middle of the brake rod, and anti-rotation sleeves are provided on the inner sides of both ends of the sleeve. The anti-rotation sleeves are sleeved on the brake rod.

[0009] To sum up, the technical solution of the utility model has the following beneficial effects compared with traditional technical means: the utility model sets a linkage mechanism between the brake mechanisms, and when in use, the brake mechanisms at the four rollers perform braking and releasing actions synchronously, which is more convenient to use, and the four rollers can be fixed in one action, and the fixation is also more stable.

[0018] The following is an ideal embodiment of the utility model. Through the following description, relevant staff can make various changes and modifications without departing from the technical concept of the utility model. The technical scope of the utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.

[0019] The utility model is further described with reference to the following drawings:

[0020] like Figures 1 to 6As shown, a convalescent bed with a foot-operated brake comprises a bed body 100, four rollers 200 are arranged at the lower part of the bed body 100, brake mechanisms 300 are arranged at the rollers 200, a linkage mechanism 400 is arranged between the brake mechanisms 300 at both ends of the bed body 100, the brake mechanism 300 comprises a brake pedal 310, a brake rod 320 and a locking pressure block 330, the brake pedal 310 is mounted at the end of the brake rod 320, the brake rod 320 is inserted in the locking pressure block 330, and the locking pressure block 330 can be pressed down when rotating, and the locking pressure block 330 can be against the rollers 200 when pressed down, and the two brake mechanisms 300 at the lower part of one end of the bed body 100 share a brake rod 320,
