Description

A three-fold electric lifting hospital bed

technical field

The utility model relates to an improvement of a hospital bed structure, in particular to a three-fold electric lifting hospital bed.

Background technique

Lifting hospital beds are generally used by people with physical disabilities or mobility problems. The bed board is designed as several adjustable bed boards to change the shape of the bed surface to adapt to the treatment or recuperation of patients. The bed board of a traditional hospital bed is generally composed of three bed boards in a hinged manner. The bed boards at both ends of the bed board are equipped with a movable support frame and a screw with a hand crank. The bed board can be adjusted by turning the hand crank set at the head of the bed. The angle of the bed blocks at both ends allows it to be raised or lowered to suit the needs of the patient. Most of the existing lifting sick beds use electric or pneumatic devices to realize the lifting of the bed boards. For example, the utility model with the patent number of 200920030733.4 discloses a three-fold sick bed. The bed boards arranged in the bed frame include four bed boards. Electric jacks acting on the bed boards are respectively installed on the racks to replace the lead screws of traditional hospital beds, so as to achieve the purpose of adjusting the angle of the bed boards. However, the jack volume is relatively large and heavy, which makes the structure of this type of lifting sick bed relatively complicated. Simultaneously, this tri-fold hospital bed does not have lifting function, which may cause inconvenient use to patients of different heights.

Contents of the invention

In view of the above-mentioned technical defects, the utility model provides a three-fold electric lift hospital bed which can adjust the height of the bed frame, adjust the angle of the bed board and turn over the guardrail.

The technical scheme of the utility model is: a three-fold electric lifting hospital bed, including a bed frame with pulleys, a bed board and a guardrail, wherein the bed board is installed on the bed frame, and an electric push rod and a support frame are arranged inside the bed frame. That is: the bed frame is installed on the foot frame through a Y-shaped lifting frame, the bed board includes 4 bed boards, and the bed boards are connected by hinges, and there are four electric push rods, and the four push rods are fixed on On the horizontal axis in the middle of the bed frame, guardrail support swing arms are movably fixed on both sides of the bed frame.

A part of the support frame is fixedly connected to the bed frame, and a part is set on the electric push rod. The support frame placed on the bed frame drives the bed plate to adjust the height or angle through the linkage of the support frame set on the electric push rod. .

There are four supporting frames, three of which support the bed blocks through pulleys, so as to adjust the height and angle of each bed block of the electric hospital bed; the other is connected with a Y-shaped lifting frame, which is convenient for adjusting the height of the bed frame .

Two guardrail support swing arms are installed on the guardrail, and the two guardrail support swing arms are connected through a guardrail linkage rod. The side rail support swing arm flips down, allowing the side rail to drop below the deck.

The beneficial effects of the utility model are:

The utility model has reasonable structure and is convenient to use. Four electric push rods can be used to adjust the height of the hospital bed, which is convenient for people of different heights to use. At the same time, the transformation mode of the bed board can be changed to increase the comfort of the user, which is beneficial to the recuperation and maintenance of the patient. Recovery, and the guardrail can be turned over as a whole, which not only protects the person on the bed, but also facilitates the user to get on and off the bed.
