DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 3 In this embodiment, a bed lifting device includes a support frame 1, a mounting frame 2 is hinged on the front of the support frame 1, an eccentric frame 3 is hinged on the front of the support frame 1, the eccentric frame 3 is internally rotatably connected with a hinge rod, the outer surface of the hinge rod is fixed to the eccentric part of the main board 4, the front of the eccentric frame 3 is hinged with the main board 4, the back of the main board 4 is hinged to the mounting frame 2, a main electric push rod 5 is arranged between the main board 4 and the mounting frame 2, the main electric push rod 5 is hinged to the back of the main board 4, the telescopic end of the main electric push rod 5 is hinged to the mounting frame 2, and the main board 4 is flipped to the prior art in the comparative document, and its operating principle is not elaborated here, a sub-plate 6 is hinged on the front of the main board 4, a stabilizing block 10 is fixed on the front of the main board 4, a stabilizing groove 11 slidably connected to the stabilizing block 10 is provided inside the sub-plate 6, and the stabilizing block 10 is arranged so that the turnover of the sub-plate 6 can be more stable.

[0026] In addition, a secondary electric push rod 7 is arranged between the main board 4 and the secondary board 6, and the secondary electric push rod 7 is used to push the secondary board 6 to rotate. The secondary electric push rod 7 is hinged to the front side of the main board 4, and the telescopic end of the secondary electric push rod 7 is hinged to the secondary board 6. The telescopic end of the main electric push rod 5 faces downward, and the telescopic end of the secondary electric push rod 7 faces upward. A stabilizing component 8 is fixed to the front side of the main board 4, and a connecting block 9 is fixed to the front side of the secondary board 6. The stabilizing component 8 is used to cooperate with the connecting block 9 to make the connection between the main board 4 and the secondary board 6 more stable.

[0027] In this embodiment, the support frame 1, the mounting frame 2 and the eccentric frame 3 are all bracket flat irons.

[0028] In general, the outer surface of the hinge rod is fixed to the eccentric part of the main board 4, so that the eccentric frame 3 will protrude a part of the main board 4 to push the sub-board 6, thereby effectively preventing the stabilizing component 8 from moving into the interior of the connecting block 9, making the whole more practical.

[0029] See also Figure 4 The stabilizing component 8 in this embodiment includes a pin buckle plate 801, a fixing bolt 802, a fixing pin 803, a fixing plate 804 and a moving component. The top of the main board 4 is fixed to the fixing plate 804, and the front of the main board 4 is fixed to the fixing pin 803. The fixed pin 803 is used to position the moving component. The fixing pin 803 penetrates the front of the fixing plate 804, and the front of the fixing pin 803 is threadedly connected to the fixing bolt 802. A threaded strip is fixed on the outer surface of the fixing bolt 802, and a threaded hole matching the threaded strip is opened on the front of the fixing pin 803. The fixing bolt 802 can fix the pin buckle plate 801.

[0030] Furthermore, the outer surface of the fixing bolt 802 is fixed to the pin buckle plate 801, and the movable component is arranged on the outer surface of the fixing pin 803. The movable component includes a swing spring 805, a swing card 806 and a swing block 807. The front side of the fixing plate 804 is fixed to the swing spring 805, the outer surface of the fixing pin 803 is rotatably connected to the swing card 806, and the back side of the swing card 806 is fixed to the swing block 807. The swing spring 805 extends to the back side of the fixing plate 804 and fits with the left and right sides of the swing card 806. Because the swing spring 805 fits with the swing card 806, the swing spring 805 will be squeezed when the swing card 806 rotates.

[0031] In general, when the connecting block 9 moves, it will squeeze the swing block 807, causing the swing block 807 to rotate to the right. When the inclined surface does not contact the swing block 807, the swing spring 805 will reset the swing block 807, thereby effectively improving the overall stability.

[0032] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0033] The working principle of the above embodiment is:

[0034] By starting the main electric push rod 5, the main board 4 can be rotated to an inclined state. This process is a prior art in the comparative document, and its operating principle will not be described in detail here. When the main board 4 rotates to an inclined state, the eccentric frame 3 will rotate, and the eccentric frame 3 is eccentrically set, so that the eccentric frame 3 will protrude a part of the main board 4 to push the sub-board 6, and control the distance between the main board 4 and the sub-board 6. Starting the sub-electric push rod 7 will further rotate the sub-board 6, so that the sub-board 6 rotates to a horizontal state. When the sub-board 6 rotates, the connecting block 9 will move together, so that the swing block 807 moves inside the connecting block 9, and the swing card 806 rotates on the outer surface of the fixing pin 803. Because the swing card 806 is in contact with the swing spring 805, the movement of the swing card 806 will cause the swing spring 805 to accumulate elastic potential energy. The movement is an arc motion, so that when the connecting block 9 moves, the swing block 807 will separate from the connecting block 9 from the left side of the connecting block 9, and when the sub-plate 6 is reset, the bottom of the connecting block 9 will contact the swing block 807, and the bottom of the connecting block 9 is in an inclined state, so that when the connecting block 9 moves, the swing block 807 will be squeezed, so that the swing block 807 rotates to the right, and when the inclined surface does not contact the swing block 807, the swing spring 805 will reset the swing block 807, so that the swing block 807 enters the interior of the connecting block 9, and when the swing block 807 is subsequently moved to the outside of the connecting block 9, it is necessary to overcome the rigidity of the swing spring 805, thereby ensuring the stability of the connection between the sub-plate 6 and the main board 4, and requiring a large force to separate the sub-plate 6 and the main board 4, effectively improving the overall stability, thereby making the overall more practical.
