Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0026] In one embodiment, as Figures 1-5As shown in the figure, a reinforced lift bed includes a square bed frame 100. A middle square plate 101 is fixedly installed at the middle position of the square bed frame 100. The connection method between the square bed frame 100 and the middle square plate 101 is tenon and mortise connection. Then, square screws are used to reinforce the middle square plate 101 and the square bed frame 100. A plurality of floor boards 102 are laid between two symmetric vertical side plates and the middle square plate 101 in the square bed frame 100. The connection between the floor boards 102, the middle square plate 101, and the square bed frame 100 is also tenon and mortise connection, and the three are fixed again by self-tapping screws. At the middle of the bottom of the plurality of floor boards 102, two symmetric vertical support plates 103 are in contact. The vertical support plates 103 are fixed to the inner sides of two transverse side plates in the square bed frame 100 by fixing bolts. The vertical support plates 103 are used to provide composite support for the floor boards 102, making the overall structure of the bed body more firm and stable. A mattress anti-slip mechanism is also fixedly installed on one of the transverse side plates of the square bed frame 100. The mattress anti-slip mechanism is a bed tail bar 104. The bed tail bar 104 is fixedly installed at the middle of the top of one of the transverse side plates of the square bed frame 100. The bed tail bar 104 is used to prevent the mattress from sliding. A dust-proof and breathable mechanism is fixedly installed at the top of the square bed frame 100. The dust-proof and breathable mechanism is an anti-slip mesh cloth 105. The anti-slip mesh cloth 105 is fixedly installed on the top surface of the square bed frame 100 and completely covers the top opening of the square bed frame 100. The anti-slip mesh cloth 105 is used for dust-proof and breathable of the bed body and can prevent abnormal noise generated by friction between the bed body and the mattress. At the bottom of the vertical support plates 103, two symmetric support cross plates 106 are in contact. The support cross plates 106 are fixedly installed on the inner sides of two vertical side plates in the square bed frame 100. A lifting assembly 200 is connected and installed at the bottom of the support cross plates 106. The support cross plates 106 drive the bed body to lift synchronously under the lifting action of the lifting assembly 200.

[0027] In one embodiment, as Figures 4-5As shown, the lifting assembly 200 includes a worm 202, which is located directly below the square bed frame 100. One end of the worm 202 is connected to a power mechanism, which is a motor 201. The motor 201 is fixed on a side wall of the limit support mechanism and is responsible for providing power. Above the worm 202, there are two worm wheels 203 engaged with each other. The worm 202 is used to drive the two worm wheels 203 to rotate. A rotating shaft 204 is fixedly connected to the inside of the worm wheel 203, and the worm wheel 203 is used to drive the rotating shaft 204 to rotate. The worm 202 and the worm wheel 203 also have a self-locking effect, specifically manifested as the worm 202 can drive the worm wheel 203 to rotate, but the worm wheel 203 cannot drive the worm 202 to rotate. Transmission gears 205 are fixedly installed at both ends of the rotating shaft 204, and the rotating shaft 204 is used to drive the transmission gears 205 to rotate. A sliding rack 206 is engaged with the side of the transmission gear 205, and the transmission gear 205 is used to drive the sliding rack 206 to move up and down. A sliding rack sleeve 207 is sleeved on the outside of the sliding rack 206, and the sliding rack sleeve 207 is used to provide a limiting effect for the movement of the sliding rack 206. A limiting mechanism is provided between the sliding rack 206 and the sliding rack sleeve 207. The limiting mechanism includes a limiting hole 211 and a limiting protrusion 212. The limiting holes 211 are opened on both sides of the sliding rack 206, and the limiting protrusions 212 are arranged on both sides of the inner wall of the sliding rack sleeve 207 corresponding to the positions of the limiting holes 211. The limiting holes 211 and the limiting protrusions 212 are used to increase the limiting effect on the sliding rack 206, making the sliding structure formed by the sliding rack 206 and the sliding rack sleeve 207 more stable. The top of the sliding rack 206 is fixedly connected to a fixed support plate 208, and the fixed support plate 208 is fixedly connected to the support cross plate 106 through a fixed bolt. The fixed support plate 208 is used to connect the bed body and the lifting assembly 200 and increase the support area of the sliding rack 206 on the support cross plate 106. The bottom of the sliding rack sleeve 207 is fixedly connected to a support plate 209. A limiting support mechanism is provided outside the worm 202 and the rotating shaft 204. The limiting support mechanism is a multi-layer limiting support plate 210, which is fixedly installed outside the worm 202 and the rotating shaft 204. The support plate 209 is fixedly connected to the side wall of the multi-layer limiting support plate 210. The support plate 209 is used to provide support for the sliding rack sleeve 207 and connect the sliding rack sleeve 207 and the multi-layer limiting support plate 210 together. The multi-layer limiting support plate 210 is used to provide limit and support for the entire device.

[0028] When the overall device is in use, power is provided to the overall device by turning on the motor 201. The motor 201 drives the worm 202 to rotate, the worm 202 drives the worm gear 203 to rotate, the worm gear 203 drives the rotating shaft 204 to rotate, the rotating shaft 204 drives the transmission gear 205 to rotate. The sliding rack 206 is limited by the sliding rack sleeve 207 and the limiting mechanism, and steadily moves upward under the drive of the transmission gear 205. The sliding rack 206 drives the bed body to move upward through the fixed support plate 208. When the motor 201 is turned off, the bed body stops moving upward. Due to the self-locking effect of the worm gear 202 and the worm 203, the bed body cannot move up and down passively. Therefore, the bed body can maintain the current height. When the motor 201 is driven in reverse, the bed body moves downward at this time. By driving the motor 201 forward and backward, the up and down movement of the bed body can be controlled.

[0029] The above embodiment discloses a reinforced lifting bed, in which a newly designed lifting component 200 supports and synchronously lifts the four corners of the bed body, so that the bed body is evenly stressed during support, the lifting is stable, the structure is firm, and the safety performance is good, solving the problems raised in the above background technology.

[0030] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
