All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0023] Embodiment 1:

[0024] As Figures 1 to 6 shown, a hospital bed dining table that is convenient for disassembly and assembly includes an upper fixed plate 101. A side support plate 104 is fixedly arranged on the upper fixed plate 101. A connecting rotating shaft 105 is arranged on the side support plate 104. A dining table board 106 is arranged on the connecting rotating shaft 105. A plurality of fixed toothed rods 102 are fixedly arranged on the upper fixed plate 101. Teeth are arranged on the fixed toothed rods 102. A lower fixed plate 103 is slidably connected to the fixed toothed rods 102. A limit pull rod 116 is arranged on the lower fixed plate 103. A limit plate 117 is fixedly arranged on the limit pull rod 116. Teeth are arranged on the limit plate 117. The teeth on the limit plate 117 are engaged with the teeth on the fixed toothed rods 102.

[0025] The position of the lower fixed plate 103 on the fixed tooth bar 102 is restricted by the teeth on the limit plate 117, thereby adjusting the distance between the upper fixed plate 101 and the lower fixed plate 103 to adapt to brackets of hospital beds of different specifications. Diagonal rods are provided on the side support plates 104, and the diagonal rods are fixedly connected to a plurality of longitudinal sliding frames 108. Strong magnets are provided on the side support plates 104 at the positions of each longitudinal sliding frame 108. The lifted longitudinal fixed rod 107 is adsorbed by magnetic force, thereby facilitating the release of the limit on the transverse fixed rod 113 and realizing the sliding of the dining table on the hospital bed bracket.

[0026] When the dining table board 106 is in use, the dining table board 106 can slide on the connecting rotating shaft 105, thereby adjusting the position of the dining table board 106, and the connecting rotating shaft 105 and the dining table board 106 can be controlled to rotate around the axis of the connecting rotating shaft 105, thereby folding up the dining table to facilitate the movement of patients and other personnel.

[0027] Such as Figure 5 and Figure 6 As shown, a reset shaft 118 is fixedly provided on the lower fixed plate 103, and a reset spring 119 is fixedly provided on the lower fixed plate 103. The reset spring 119 is sleeved on the reset shaft 118, the reset spring 119 is fixedly connected to the limit pull rod 116, and the reset shaft 118 is slidably connected to the limit pull rod 116.

[0028] Specifically, when the dining table of the present application needs to be installed on the hospital bed bracket, first manually pull the limit pull rod 116 to make the teeth of the limit plate 117 on the limit pull rod 116 disengage from the teeth of the fixed tooth bar 102, thereby releasing the restriction on the lower fixed plate 103. Thus, the lower fixed plate 103 can slide up and down on the fixed tooth bar 102 to adapt to the size of the hospital bed bracket. After inserting the upper fixed plate 101 and the lower fixed plate 103 into the hospital bed bracket, the upper fixed plate 101 and the lower fixed plate 103 are closely attached to the upper and lower end faces of the hospital bed bracket, and the limit pull rod 116 is reset. The limit pull rod 116 controls the teeth on the limit plate 117 to engage with the teeth on the fixed tooth bar 102 again, thereby restricting the movement of the lower fixed plate 103, fixing the distance between the upper fixed plate 101 and the lower fixed plate 103, and making the upper fixed plate 101 and the lower fixed plate 103 closely attached to the hospital bed bracket to prevent the dining table from shaking due to excessive gaps between the upper fixed plate 101, the lower fixed plate 103 and the hospital bed bracket during use.

[0029] A plurality of transverse fixing blocks 114 are fixedly arranged on the upper fixing plate 101. A transverse fixing rod 113 is slidably connected to the transverse fixing blocks 114. A retaining rod is arranged on the transverse fixing rod 113. The first end of a transverse spring 115 is fixedly connected to the transverse fixing rod 113, and the second end of the transverse spring 115 is fixedly connected to the transverse fixing blocks 114. By pushing the retaining rod of the transverse fixing rod 113 away from the transverse fixing blocks 114, the transverse fixing rod 113 can be pulled to slide on the transverse fixing blocks 114, thereby controlling the part of the transverse fixing rod 113 inserted into the hospital bed bracket to slide out and compressing the transverse spring 115 on the transverse fixing rod 113, so as to release the restriction that the upper fixing plate 101 and the lower fixing plate 103 cannot slide on the hospital bed bracket, enabling the patient and the caregiver to push the dining table to slide on the hospital bed bracket and adjust it to a suitable position, which is convenient for the patient to move and other situations.

[0030] A first connecting shaft 110 is rotatably arranged on the upper fixing plate 101. A first connecting block 109 is rotatably arranged on the first connecting shaft 110. A second connecting shaft 112 is rotatably arranged on the first connecting block 109. A control long rod 111 is rotatably arranged on the second connecting shaft 112.

[0031] A torsion spring is arranged between the first connecting shaft 110 and the first connecting block 109, and a torsion spring is arranged between the second connecting shaft 112 and the control long rod 111.

[0032] A plurality of longitudinal fixing rods 107 are slidably connected to the upper fixing plate 101. A push rod and a slider are arranged on each longitudinal fixing rod 107. A plurality of longitudinal sliding frames 108 are fixedly arranged on the upper fixing plate 101. The slider of the longitudinal fixing rod 107 is slidably connected to the chute of the longitudinal sliding frame 108. During use, the longitudinal fixing rods 107 are inserted into appropriate holes on the hospital bed bracket to fix the position of the upper fixing plate 101 on the hospital bed bracket and prevent the dining table from shaking. The heights of the longitudinal sliding frames 108 decrease step by step. As Figure 3 shown, the 4 longitudinal sliding frames 108 on the upper fixing plate 101 form an inclined plane that gradually increases from left to right. The longitudinal sliding frames 108 are fixed by the inclined rods on the side support plate 104. Due to the different heights of the longitudinal sliding frames 108, the four longitudinal fixing rods 107 can simultaneously contact the strong magnets on the inclined rods of the side support plate 104, that is, be adsorbed and fixed simultaneously, so as to proceed to the next step, that is, control the pushing out of the transverse fixing rod 113.

[0033] As Figures 1 to 6As shown, specifically, when it is necessary to adjust the position of the dining table on the hospital bed, that is, the dining table slides on the hospital bed bracket, the control long rod 111 is manually controlled to drive the first connecting block 109 to rotate on the first connecting shaft 110, so that the control long rod 111 is away from the transverse fixing rod 113. When the control long rod 111 rotates, it will gradually push the multiple longitudinal fixing rods 107 on the upper fixing plate 101, and push the longitudinal fixing rods 107 to slide upward on the longitudinal sliding frame 108, and finally make the multiple longitudinal fixing rods 107 contact the strong magnets on the oblique rods of the side support plate 104 at the same time, and the longitudinal fixing rods 107 are adsorbed by magnetic force to fix the position of the longitudinal fixing rods 107 on the longitudinal sliding frame 108, thereby contacting the restriction between the longitudinal fixing rods 107 and the hospital bed bracket; then the control long rod 111 is controlled to reset, and in the horizontal direction The control rod 111 is rotated upward in the direction away from the upper fixing plate 101, so that the control rod 111 pushes the multiple transverse fixing rods 113 away from the upper fixing plate 101, and then the transverse fixing rod 113 slides out on the transverse fixing block 114, so that the part of the transverse fixing rod 113 inserted into the bed support slides out and no longer forms a restriction with the bed support, so that the upper fixing plate 101 and the lower fixing plate 103 can slide on the bed support; then the position of the dining table is adjusted, and after adjusting to the appropriate position, the control of the control rod 111 is released, and the transverse fixing rod 113 is reset under the action of the transverse spring 115 and pushes the control rod 111 to reset, and the four longitudinal fixing rods 107 on the inclined rod of the side support plate 104 are manually pressed downward to make it break away from the adsorption of the strong magnet on the inclined rod, and then automatically fall down by gravity and insert into the hole position on the bed support.

[0034] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
