Description

A kind of multi-angle adjustment structure of bed board

technical field

The invention relates to the technical field of medical equipment, and more particularly to a multi-angle adjustment structure of a bed board.

Background technique

With the increasing aging of the country, the domestic demand for multifunctional medical beds and nursing beds is also increasing, which has resulted in the blowout development of nursing bed products. Patients often need to adjust their body position with the help of nursing staff.

In the prior art, traditional medical beds or nursing beds are usually fixed, or can only be tilted in a single direction, without considering the need to change the focal point of the buttocks of the patient's back due to changes in the angle; In the prior art, the adjustment structure of the medical bed or the nursing bed is relatively simple. Generally, the inclination angle of the bed can only be manually adjusted by a doctor or an escort, which is time-consuming and labor-intensive, and cannot achieve patient satisfaction.

Therefore, traditional functional medical beds and nursing beds cannot meet people's diverse living needs.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a multi-angle adjustment structure of the bed board. Through the unique segmented bed board design and adjustment control, the lifting and angle adjustment of the upper body of the patient can be realized, so as to meet the diverse needs of the patient for the height and angle of the backrest, For a more comfortable and convenient lying experience.

In order to achieve the above object, the present invention adopts the following technical solutions:

A multi-angle adjustment structure for a bed board, comprising a bed support and a bed board; it is characterized in that it further comprises: a rack board and a driving mechanism; wherein:

The bed board also includes a connecting back board, a support frame, a buttocks support board, and a fixed board; an arc-shaped support board track is provided downward in the middle of the fixed board; one end of the buttocks support board is pivotally connected to the support frame, and the other end can be The track of the extension plate slides freely in the arc-shaped direction; one end of the support frame close to the buttocks support plate is also fixed with a back slider and a back motor seat; the back slider is provided with a number of tooth grooves; the back motor seat is used to connect And fix the drive mechanism;

The lower support connecting piece is fixed symmetrically on both sides of the bed frame; the lower support connecting piece is axially connected with one end of the rack plate; The grooves mesh with the grooves on the back slider;

The driving mechanism is provided with two groups on the left and right, and each group is composed of a push rod and a motor respectively; the tail end of the push rod is axially connected with the back motor seat; the motor is fixedly installed on both sides of the bed frame.

Beneficial effect: The multi-angle adjustment structure of the bed board can be used in fields such as medical beds and nursing beds. The height and angle of the back part and the legs and hip parts can be adjusted through the synchronous movement of the motors on both sides, and the structure can freely adjust the degree of back bending. and the sink height of the hip support. The backboard support frame is connected with the motor and the push rod. The motor drives the push rod to expand and contract, and controls the push rod's telescopic speed, thereby controlling the lift of the backboard; The other end can slide freely along the arc direction of the track of the support board. When the back board is raised, the distance between the back board and the fixed board will be increased correspondingly due to the push of the motor. At this time, the buttock support board will extend The arc-shaped direction of the pallet rail slides freely to the bottom, so as to achieve the diversification of various positions and angles in the horizontal and vertical directions of the two bed boards during the lifting process, and realize the linkage between the back and the buttocks.
