For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0029] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of the technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0030] The hospital beds used by inpatients have been continuously improved in function after a long evolution, thus providing great convenience to inpatients. For example, both sides of the bed frame of the existing hospital bed are equipped with foldable guardrails. One is that it can prevent patients from rolling off the bed during rest, and the other is that it can be used to place the dining table (tabletop) during meals.

[0031] In the related art, generally, a dining table is directly placed on the hospital bed for use. However, due to the fact that there are generally quilts on the hospital bed, which are relatively soft, the table is not stable enough and easy to shake. In addition, the height of the table is generally fixed, which may be too high or too low for patients with different individual differences. Therefore, the comfort of patients during use is insufficient.

[0032] To solve the problems in the related art to a certain extent, the embodiment of the present application provides a lifting mechanism for a medical bed. When a patient needs to eat, first use the electric telescopic rod 12 to push the bed body 11 to rotate and adjust the angle of the backrest, and then start the motor 21 to drive the rotating rod 22 to rotate, so that the gear 23 meshes with the rack 25, driving the rack 25 to move upward through the frame body 24. After adjusting to a suitable height, place the cross plate 27 on the mounting block 26. The mounting block 26 is inserted into the hole groove on the cross plate 27. During the insertion process, the clamping block 32 is squeezed and retracted into the interior of the mounting block 26 until the clamping block 32 aligns with the clamping groove 31, and then the spring 33 rebounds to push the clamping block 32 to move and insert into the interior of the clamping groove 31. The food can be placed on the cross plate 27 for use. When it is necessary to disassemble the cross plate 27, only need to push the two push blocks 35 closer to drive the convex block 34 to move, so that the two clamping blocks 32 approach and retract into the interior of the mounting block 26 to disengage from the clamping groove 31, then the fixation of the cross plate 27 can be released, and then the cross plate 27 is inserted into the interior of the placement groove 29 for storage.

[0033] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0034] Combined with Figures 1 - 4 In this regard, the embodiment of the present application provides a lifting mechanism for a medical bed, including: a bed body 11, at the bottom of which an electric telescopic rod 12 is provided; a lifting assembly 2 is provided on one side of the bed body 11, and the lifting assembly 2 includes: a motor 21 fixedly arranged at the bottom of the bed body 11; a rotating rod 22 arranged on the output shafts at both ends of the motor 21; a gear 23 arranged at one end of the rotating rod 22; a frame body 24 symmetrically and fixedly arranged on both sides of the bed body 11; a rack 25, the bottom of which is inserted into the frame body 24 and meshes with the gear 23; a mounting block 26 arranged at the top of the rack 25; a cross plate 27 inserted on the top of the mounting block 26.

[0035] Specifically, the motor 21 is designed as a double-headed motor, and the mounting block 26 is welded and fixed to the rack 25.

[0036] During use, when a patient needs to eat, first use the electric telescopic rod 12 to push the bed body 11 to rotate and adjust the angle of the backrest, and then start the motor 21 to drive the rotating rod 22 to rotate, so that the gear 23 meshes with the rack 25, driving the rack 25 to move upward through the frame body 24. After adjusting to a suitable height, place the cross plate 27 on the mounting block 26. The mounting block 26 is inserted into the hole groove on the cross plate 27, and the food can be placed on the cross plate 27 for use.

[0037] During use, when it is necessary to fix the cross plate 27,

[0038] In one of the technical solutions disclosed by the present utility model, the outer sidewall of the rack 25 is attached to the inner sidewall of the frame 24.

[0039] During use, the attached design can prevent the rack 25 from shaking easily when moving up and down.

[0040] In one of the technical solutions disclosed by the present utility model, the lifting assembly 2 further includes: a baffle 28 disposed at the bottom of the rack 25.

[0041] During use, it can prevent the rack 25 from separating from the frame 24.

[0042] In one of the technical solutions disclosed by the present utility model, the lifting assembly 2 further includes: a placement groove 29 formed on the outer sidewall of the baffle 28.

[0043] During use, the provision of the placement groove 29 enables the cross plate 27 to be inserted into the interior of the placement groove 29 when the cross plate 27 is not in use.

[0044] In one of the technical solutions disclosed by the present utility model, the inner sidewall of the placement groove 29 is attached to the outer sidewall of the cross plate 27.

[0045] During use, the attached design results in a larger contact surface, thereby increasing the friction and reducing the situation of slipping.

[0046] In one of the technical solutions disclosed by the present utility model, a fixing assembly 3 is provided inside the mounting block 26. The fixing assembly 3 includes: clamping grooves 31 symmetrically formed inside the cross plate 27; one end of a clamping block 32 symmetrically penetrates the inner sidewall of the mounting block 26 and is engaged with the clamping groove 31; a spring 33 is disposed inside the mounting block 26 and both ends are connected to the clamping block 32; the bottom of a convex block 34 is inserted into the mounting block 26 and connected to the clamping block 32.

[0047] During use, by pushing the two convex blocks 34 to move, the two clamping blocks 32 approach each other and retract into the interior of the mounting block 26. Then, the mounting block 26 is inserted into the hole groove on the cross plate 27. Subsequently, the convex blocks 34 are released, and the spring 33 rebounds to push the clamping blocks 32 to insert into the interior of the clamping grooves 31 to fix the cross plate 27.

[0048] In one of the technical solutions disclosed by the present utility model, the top of the clamping block 32 has an inclined surface design.

[0049] During use, due to the inclined surface design, when the mounting block 26 is inserted into the hole groove on the cross plate 27, direct pressing can cause the clamping block 32 to retract into the interior of the mounting block 26 until the clamping block 32 aligns with the clamping groove 31. Then, the spring 33 rebounds to push the clamping block 32 to move and insert into the interior of the clamping groove 31 for fixation.

[0050] In one of the technical solutions disclosed by the present utility model, the fixing component 3 further includes: a pushing block 35 disposed on the top of the bump 34.

[0051] During use, the design of the pushing block 35 facilitates grasping and pushing.
