Abstract

A connecting rod supporting arm, a fixed supporting arm and a gas compression rod are sequentially connected between a bed board fixing piece and a bed frame fixing piece in a shaft connection mode, wherein the lower portion of the connecting rod supporting arm is connected with one end of a driving arm, the other end of the driving arm is connected with the bed frame fixing piece in a shaft connection mode, the fixed supporting arm and the driving arm are the same rotating shaft, a limiting hole is formed in the driving arm, and a limiting block is arranged at the position, corresponding to the limiting hole, of the bed frame fixing piece. When the lifting mechanism is used, when the bed board at the tail end of the bed is lifted, the lifting mechanism can obliquely support the bed board, when the bed board is pulled again, the driving arm is forced to upwards overturn, the bed board can be horizontal when the driving arm rotates to the limiting block limiting position, and the lifting mechanism can horizontally support the bed board. The utility model discloses simple structure, easy to use.

Description

Lifting mechanism

Technical Field

The utility model relates to a furniture product lifts and uses part, a lifting mechanism specifically says so.

Background

In some conventional bed products, in order to utilize the space below the mattress, a lifting mechanism is mounted on a bed plate fixture and a bed frame fixture below the mattress so as to lift the mattress. The existing lifting mechanism mainly comprises a bed board fixing piece fixed on a bed board and a bed frame fixing piece fixed on a frame of the bed frame, wherein the bed board fixing piece is connected with one end of the bed frame fixing piece through a shaft, and the bed board fixing piece is connected with the bed frame fixing piece through a pneumatic rod at the far end of the shaft connection. When the tail end of the bed board is lifted, the bed board fixing piece rotates upwards, the air pressure rod is stretched, and therefore the tail end of the bed board can be lifted upwards, and the bed board is an inclined plane. When the bed board is pressed downwards, the telescopic rod is shortened, and the bed board fixing piece rotates downwards along the rotating shaft, so that the bed board is in a horizontal normal use state. Such lifting mechanisms can only achieve a single lifting function, so that when articles are on the mattress, people often firstly move the articles on the bed away and then lift the mattress, which brings inconvenience to people. Therefore, it is necessary to provide a lifting mechanism which can lift the mattress in different ways and is convenient for people to use.

Disclosure of Invention

In order to solve the problem that current lifting mechanism exists, the utility model provides a lifting mechanism, this lifting mechanism not only can realize the bearing diagonal to the mattress, can realize the horizontal support moreover.

The utility model provides a technical scheme that its technical problem adopted is: a fixed supporting arm and an air compression bar are connected between a bed board fixing piece and a bedstead fixing piece, wherein one end of the bed board fixing piece and one end of the bedstead fixing piece are connected with a connecting rod supporting arm, the lower part of the connecting rod supporting arm is connected with one end of a driving arm, the other end of the driving arm is connected with a bedstead fixing piece shaft, the fixed supporting arm and the driving arm are the same rotating shaft, a limiting hole is formed in the driving arm, and a limiting block is arranged at a position, corresponding to the limiting hole, on the bedstead fixing piece.

The utility model has the advantages that: can also realize the horizontal support to the mattress according to the use needs when realizing mattress bearing diagonal, and then need not remove the article on the mattress, do benefit to people and use.

Drawings

The present invention will be further explained with reference to the accompanying drawings.

Fig. 1 is a schematic plan view of the present invention in a closed state.

Fig. 2 is a schematic plan view of the present invention in an inclined supporting state.

Fig. 3 is a schematic plan view of the present invention in a horizontal supporting state.

Code description in the figure: 1-bed board fixing parts; 2-bedstead fixing parts; 3-a link support arm; 4-fixing the support arm; 5-air pressure rod; 6-the driving arm; 7-limiting holes; and 8, a limiting block.

Detailed Description

In the following description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "middle", "inner", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, nor that it should indicate a different structure, and thus should not be construed as limiting the present invention.

As shown in fig. 1, 2 and 3, a fixed support arm 4 and an air pressure rod 5 are connected between a bed board fixing member 1 and a bed frame fixing member 2, wherein one end of the bed board fixing member 1 and one end of the bed frame fixing member 2 are connected with a connecting rod support arm 3, the lower part of the connecting rod support arm is connected with one end of a driving arm 6, the other end of the driving arm is connected with the bed frame fixing member 2 through a shaft, the fixed support arm and the driving arm are the same rotating shaft, the driving arm is provided with a limit hole 7, and a limit block 8 is arranged on the bed frame fixing member at a position corresponding to the limit hole. The utility model discloses in each junction be the hub connection to ensure that each part can rotate smoothly can. When in use, the bedstead fixing parts are fixedly arranged at two sides of the inner side of the bedstead frame, and the bed board fixing parts are fixedly arranged at two sides of the lower side of the bed board. When the tail end of the bed plate is lifted, the bed plate fixing piece rotates along the connecting point of the connecting rod supporting arms, the air pressure rod is elongated, the lifting mechanism is in an inclined supporting state as shown in figure 2, when the bed plate is pulled again, the bed plate fixing piece drives the driving arm to rotate upwards along the rotating shaft, when the bed plate rotates to the position of the limiting block, the driving arm stops rotating, and at the moment, the bed plate is in a horizontal supporting state as shown in figure 3. The utility model discloses can realize the different mode of opening, do benefit to people and use. The product has simple structure and is beneficial to popularization.

Claims
