Abstract

The invention discloses an automatic support mechanism applied to a nursing bed, which comprises an L-shaped support, an electric push rod, and a rotating support block. The L-shaped support is fixed on both sides of the nursing bed, and the rotating support block is hingedly connected. On the L-shaped bracket, while the electric push rod is installed between the L-shaped bracket and the rotating support block, when the foot plate of the nursing bed moves to a horizontal position and needs to bear downward positive pressure, the foot plate of the cantilever structure is not enough to provide sufficient support At this time, the electric push rod is extended, and the rotating support block is pushed to rotate at a certain angle around the rotation axis. When the support surface and the bottom surface of the foot plate are kept horizontal, the upward thrust is provided by the self-locking force of the push rod. When the footboard needs to move downward, the electric push rod shrinks, and the rotating support block avoids the movement track of the footboard, so as to complete the leg bending action. The mechanism is exquisite in structure, easy to use, strong in self-locking force, and can provide sufficient supporting force to ensure the safety and stability of the bed body.

Description

An automatic support mechanism applied to a nursing bed

technical field

The invention relates to the field of support mechanisms, in particular to an automatic support mechanism applied to nursing beds.

Background technique

With the popularization of intelligent nursing beds, more and more nursing beds have added actions such as raising legs and bending legs under the premise of ensuring the functions of the bed body, which means that the legs and feet of the nursing bed should be able to move to the bed surface The space below, so that the bottom movement space of the legs and feet must ensure that there is no interference, which causes the legs and feet to form a cantilever state in a horizontal state, which cannot bear a large positive pressure, so that many The nursing bed will be marked with a warning that it is strictly forbidden to sit at the end of the bed. This not only makes the nursing bed unable to achieve the function that an ordinary bed should have, but also increases the probability of damage to the nursing bed and increases safety hazards.

At present, there are many mechanisms that provide positive support for equipment or mechanisms with limited bearing capacity. However, while providing sufficient bearing capacity, they also cause movement interference in the direction of the force. Therefore, a mechanism that can provide support and A support mechanism that can avoid movement interference, and at the same time can automatically complete the action to echo the intelligence of the nursing bed.

Contents of the invention

In order to overcome the problems of insufficient bearing capacity, movement interference and intelligent control, the present invention provides an automatic support mechanism applied to nursing beds, which can provide sufficient upward support when needed, and avoid being supported at an appropriate time The movement trajectory of the parts has met the requirements for the use of intelligent nursing beds.

The technical solution adopted by the present invention to solve the technical problem is: an automatic support mechanism applied to a nursing bed, including an L-shaped bracket, an electric push rod, and a rotating support block. The L-shaped bracket is welded by several parts to form an L-shaped Components provide a reasonable space for the movement of the push rod. The L-shaped bracket is fixed on both sides of the nursing bed, the rotating support block is connected to the mounting bracket in a hinged form, and the electric push rod is mounted on the bracket in a hinged connection. Between the rotating support block and the rotating support block, when the footboard of the nursing bed moves to a horizontal position and needs to bear downward positive pressure, the electric push rod is extended at this time, pushing the rotating support block to rotate at a certain angle around the rotation axis until the support surface and The foot plate remains horizontal, relying on the self-locking force of the push rod to provide upward thrust. When the foot plate needs to move downward to complete the leg bending action, the electric push rod shrinks at this time, and the rotating support block avoids the movement track of the foot plate to complete the leg bending action.

The beneficial effect of the present invention is that, when the automatic support mechanism of the present invention is applied to a nursing bed, it can not only provide a reliable support force, but also avoid the interference problem caused by the support mechanism to the necessary movement, and can also automatically complete the action, thereby The intelligence, safety and stability of the nursing bed are guaranteed.

【Example】

The automatic support mechanism applied to nursing beds includes L-shaped bracket 1, electric push rod 2, and rotating support block 3. The support mechanism works for two groups at the same time, supports both sides of the foot plate, and provides stable support. The L-shaped bracket 1 is welded by several parts to form an L-shaped assembly, which provides a reasonable space for the movement of the push rod. The L-shaped bracket 1 is fixed on both sides of the nursing bed 5, and the rotating support block 3 is connected in a hinged form. On the mounting bracket, the electric push rod 2 is installed between the bracket and the rotating support block in a hinged connection. When the foot plate 4 of the nursing bed moves to a horizontal position, the leg plate and the foot plate partly form a cantilever structure, and its own The locking force is not enough to support a large gravity. For example, when a person sits at the end of the bed, the end of the bed has to bear a large downward positive pressure. At this time, the electric push rod 2 is extended to push the rotating support block 3 to rotate at a certain angle around the rotation axis. , until the supporting surface and the foot plate 4 remain horizontal, relying on the self-locking force of the push rod 2 to provide an upward thrust. When the foot plate 4 needs to move downward to complete the leg bending action, the electric push rod 2 shrinks now, and the rotating support block 3 avoids the motion track of the foot plate to complete the leg bending action.

In this embodiment, the above-mentioned rotating support block 3 can rotate more than 90 degrees in the clockwise direction to ensure that the movement of the supported foot plate 4 is not hindered. According to actual needs, the specific rotation angle can be changed within the practical application range.

In this embodiment, the stroke of the electric push rod 2 is reasonably selected according to the size of the bed body, and the specific stroke size is not limited.
