For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0038] like Figure 1 to Figure 2 , Figures 5 to 7 As shown, in one embodiment, a multifunctional dining table 1 includes a base frame 10 and a supporting assembly 20, and the supporting assembly 20 includes a lifting member 21, a fixed plate 22, an axle connection column 23, a fixed tooth seat 24, an angle plate 25, a shaft sleeve 26, a movable tooth seat 27, and a locking member 28. The lifting member 21 is arranged on the triangular piece 11, the fixed plate 22 is arranged on the lifting member 21, the axle connection column 23 is arranged on the fixed plate 22, the fixed tooth seat 24 is arranged on the axle connection column 23, the shaft sleeve 26 is arranged on the angle plate 25, and the shaft sleeve 26 is sleeved with the axle connection column 23 so that the angle plate 25 can rotate relative to the fixed plate 22, the movable tooth seat 27 is arranged on the shaft sleeve 26, the locking member 28 is penetrated by the axle connection column 23, and the locking member 28 is screwed with the shaft sleeve 26. When the locking member 28 rotates, the movable tooth seat 27 is meshed with the fixed tooth seat 24.

[0039] It should be noted that the angle plate 25 is fixedly arranged on the shaft sleeve 26, the fixed plate 22 is fixedly arranged on the shaft connection column 23, and the shaft sleeve 26 is sleeved with the shaft connection column 23, so that the shaft sleeve 26 can drive the angle plate 25 to rotate relative to the fixed plate 22, thereby forming an angle between the angle plate 25 and the fixed plate 22. Further, the movable gear seat 27 is fixedly arranged on the shaft sleeve 26, and the fixed gear seat 24 is fixedly arranged on the shaft connection column 23. When the shaft sleeve 26 is sleeved with the shaft connection column 23, the movable gear seat 27 and the fixed gear seat 24 can move closer to each other for engagement or move away from each other for disengagement. In this way, when the shaft sleeve 26 is sleeved with the shaft connection column 23, so that the movable gear seat 27 is engaged with the fixed gear seat 24, the angle plate 25 cannot rotate relative to the fixed plate 22, thereby maintaining the angle between the angle plate 25 and the fixed plate 22.

[0040] In one embodiment, when the locking member 28 rotates to drive the shaft sleeve 26 away from the shaft connection column 23, the movable tooth seat 27 and the fixed tooth seat 24 are disengaged, and the angle plate 25 can rotate relative to the fixed plate 22. When the angle plate 25 is rotated to be parallel to the fixed plate 22, the locking member 28 is rotated again to make the shaft sleeve 26 close to the shaft connection column 23, so that the movable tooth seat 27 and the fixed tooth seat 24 are close to meshing, so as to maintain the fixed state of the angle plate 25 and the fixed plate 22. In this way, the angle plate 25 and the fixed plate 22 can be combined into a plane, so that the patient can have a larger dining table. Further, when the locking member 28 rotates to drive the shaft sleeve 26 away from the shaft connection column 23, the angle plate 25 can rotate relative to the fixed plate 22. When the angle plate 25 is rotated to form an angle with the fixed plate 22, the locking member 28 is rotated again to make the shaft sleeve 26 close to the shaft connection column 23, so that the movable tooth seat 27 and the fixed tooth seat 24 are close to meshing. Furthermore, stop bars 251 are provided on both sides of the angle plate 25, so that the angle plate 25 is tilted relative to the fixed plate 22, so that the patient can read or write on the dining table, thereby improving the patient's quality of life and rehabilitation effect during the recuperation process.

[0041] It should be noted that the triangular piece 11 is arranged on one end of the base frame 10, one end of the lifting member 21 is arranged on the triangular piece 11, and the other end of the lifting member 21 is arranged on the end of the fixed plate 22 away from the angle plate 25, so that the fixed plate 22, the lifting member 21 and the base frame 10 form a "U"-shaped structure. In this way, the angle plate 25 can extend from the edge of the bed to the middle of the bed, so that the patient can eat while sitting on the bed, avoiding the need for the patient to get up and turn the body to the bedside, thereby improving the patient's rehabilitation effect.

[0042] like Figure 6 As shown, in one embodiment, the locking member 28 includes a screw block 281, a screw rod 282 and a handwheel 283. The screw block 281 is disposed in the shaft sleeve 26, the screw rod 282 is passed through the shaft connecting column 23, and the screw rod 282 is screwed to the screw block 281. The handwheel 283 is disposed on the screw rod 282, and the handwheel 283 is used to rotate the screw rod 282.

[0043] It should be noted that the screw block 281 is arranged in the shaft sleeve 26. For example, the circumferential surface of the screw block 281 is provided with two opposite grooves. The tube wall of the shaft sleeve 26 is clamped inwardly into the two grooves of the screw block 281 by a clamp, so that the screw block 281 is fixed in the shaft sleeve 26. Further, the shaft connection column 23 is arranged on the fixing plate 22, and the screw rod 282 is passed through the shaft connection column 23. When the shaft sleeve 26 is sleeved with the shaft connection column 23, one end of the screw rod 282 can be screwed with the screw block 281 in the shaft tube, and the hand wheel 283 is arranged on the other end of the screw rod 282. The hand wheel 283 is used to drive the screw rod 282 to rotate. In this way, when the hand wheel 283 is rotated, the screw block 281 drives the shaft sleeve 26 to approach the shaft connection column 23 or move away from the shaft connection column 23, so that the movable gear seat 27 and the fixed gear seat 24 can approach each other for meshing or move away from each other for loosening.

[0044] like Figure 6 As shown, in one embodiment, the support assembly 20 further includes an elastic member 29 , which is sleeved on the screw rod 282 , and the elastic member 29 abuts against the screw block 281 and the shaft connection column 23 , respectively.

[0045] It should be noted that the elastic member 29 is a spring structure, and the spring is sleeved on the screw rod 282. Since the screw block 281 is fixedly arranged in the shaft sleeve 26, and the shaft sleeve 26 is sleeved on the shaft connection column 23, when the screw rod 282 rotates, the hand wheel 283 pushes the shaft connection column 23 away from one end of the shaft sleeve 26, so that the screw rod 282 drives the screw block 281 to approach the shaft connection column 23, and then the movable tooth seat 27 on the shaft sleeve 26 is close to the fixed tooth seat 24 on the shaft connection column 23 to engage, and at the same time, the screw block 281 presses the spring toward the shaft connection column 23. Further, when the screw rod 282 rotates in the opposite direction, the spring pushes the screw block 281 away from the shaft connection column 23, and then the movable tooth seat 27 on the shaft tube is away from the fixed tooth seat 24 on the shaft connection column 23 to disengage, so that the angle plate 25 can be rotated relative to the fixed plate 22 to adjust the angle.

[0046] like Figure 1 to Figure 2 , Figures 7 and 8 As shown, in one embodiment, the lifting member 21 includes a support tube 211, a lifting tube 212, a bracket 213, a pressing plate 214 and a telescopic rod 215. The support tube 211 is arranged on the triangular plate 11, the lifting tube 212 is sleeved on the support tube 211, the bracket 213 is arranged on the lifting tube 212, and the fixing plate 22 is arranged on the bracket 213.

[0047] It should be noted that the support tube 211 is fixedly arranged on the triangular piece 11, one end of the lifting tube 212 is sleeved on the support tube 211, and the bracket 213 is arranged on the end of the lifting tube 212 away from the triangular piece 11, so that when the lifting tube 212 slides relative to the support tube 211, it can drive the bracket 213 to lift and slide. The fixed plate 22 is arranged on the bracket 213, so that when the lifting tube 212 is lifted and slid, the fixed plate 22 can be lifted and slid, and then the lifting tube 212 drives the angle plate 25 to lift and slide. Further, the telescopic rod 215 is a gas pressure rod structure, the gas pressure rod is fixedly arranged in the support tube 211 along the vertical direction, and the output end of the gas pressure rod is fixed on the end of the lifting tube 212 away from the triangular piece 11. The pressing plate 214 is rotatably arranged on the bracket 213, and one end of the pressing plate 214 is located in the middle position of the bracket 213, so that it can press the switch of the gas pressure rod. In this way, when the pressing piece 214 rotates to press the switch of the gas pressure rod, the output end of the gas pressure rod pushes the lifting tube 212 to lift and slide, thereby driving the fixing plate 22 to lift and slide.

[0048] like Figure 1 to Figure 2 , Figures 7 and 8 As shown, the base frame 10 is provided with a plurality of universal wheels.

[0049] It should be noted that universal wheels are provided at both ends of the supporting frame 13, and two universal wheels are provided opposite to one end of the folding frame 14 away from the supporting frame 13. In this way, when the supporting frame 13 and the folding frame 14 are in a horizontal plane, the universal wheels jointly drive the supporting assembly 20 to slide, so that the patient can easily move the multifunctional dining table 1 of the present application.

[0050] like Figures 2 to 3 , Figure 8 As shown, in one embodiment, the multifunctional dining table 1 also includes a slider 30 and a top locking member 40. The slider 30 is arranged on a side surface of the bracket 213. The bracket 213 is rotatably arranged on an end of the lifting tube 212 away from the triangular piece 11, so that when the bracket 213 rotates relative to the lifting tube 212, it can drive the slider 30 to rotate.

[0051] It should be noted that the slider 30 is an arc-shaped structure, and two slots are provided on the slider 30. For the convenience of description, the two slots are defined as the first slot 31 and the second slot 32, respectively, and the two slots are located at the two ends of the arc edge. Further, the top lock 40 includes a top column 41, a top seat 42 and a push spring 43. The top seat 42 is fixedly arranged on one side of the lifting tube 212, and the top seat 42 is close to the arc edge of the slider 30. The top column 41 is an "L"-shaped structure, and the top column 41 is slidably arranged in the top seat 42. The push spring 43 is used to push the top column 41 to slide out of the top seat 42. Furthermore, when the bracket 213 drives the fixed plate 22 to rotate downward, it also drives the slider 30 to rotate downward, so that when the fixed plate 22 and the lifting tube 212 are in a parallel state, the arc edge of the slider 30 slides along the top seat 42, and when the second slot 32 slides to the top seat 42, the push-up spring 43 will push the top column 41 from the top seat 42 to slide into the second slot 32, so that the slider 30 cannot slide, and the bracket 213 cannot drive the fixed plate 22 to rotate, so as to keep the fixed plate 22 and the lifting tube 212 in a parallel state. Furthermore, the bracket 213 drives the fixed plate 22 to rotate upward, and at the same time drives the slider 30 to rotate upward, so that when the fixed plate 22 and the lifting tube 212 are in a vertical state, the arc edge of the slider 30 slides against the top seat 42, and when the first slot 31 slides to the top seat 42, the push spring 43 pushes the top column 41 from the top seat 42 to slide into the first slot, so that the slider 30 cannot slide, and the bracket 213 cannot drive the fixed plate 22 to rotate, so as to keep the fixed plate 22 and the lifting tube 212 in a vertical state. In this way, the top column 41 can be pulled away from the slot, so that the fixed plate 22 can be folded or unfolded relative to the lifting tube 212.

[0052] like Figure 1 to Figure 2 , Figures 7 to 12 As shown, in one embodiment, the base frame 10 includes a hinge block 12, a supporting frame body 13 and a folding frame body 14, the triangular piece 11 is arranged on the supporting frame body 13, the hinge block 12 is arranged on the folding frame body 14, and the hinge block 12 is rotatably connected to the triangular piece 11 so that the folding frame body 14 can rotate relative to the supporting frame body 13.

[0053] It should be noted that the support frame 13 tends to be an "I"-shaped structure, the folding frame 14 tends to be a "T"-shaped structure, and one end of the folding frame 14 is rotatably connected to the middle section of the support frame 13, so that the folding frame 14 can rotate relative to the support frame 13. Further, the triangular piece 11 is located in the middle section of the support frame 13, and a rotating shaft portion 112 is provided on one corner of the triangular piece 11, and the rotating shaft portion 112 is two side-by-side circular ring structures. The hinge block 12 is arranged on one end of the folding frame 14 close to the supporting frame body 13, and a connecting portion 122 is opened on the hinge block 12. The connecting portion 122 has the same structure as the rotating shaft portion 112, and both are two side-by-side circular ring structures. The two circular ring structures on the connecting portion 122 are adaptively plugged into the two circular ring structures on the rotating shaft portion 112. For example, the connecting portion 122 is rotatably connected to the rotating shaft portion 112 through a latch, so that the connecting portion 122 can rotate relative to the rotating shaft portion 112, and then the folding frame 14 can rotate relative to the supporting frame body 13.

[0054] It should be noted that the two side-by-side circular ring structures on the rotating shaft portion 112 are provided with a locking groove 1121, which penetrates the two side-by-side circular rings and is opened toward the supporting tube 211. Furthermore, the two side-by-side circular ring structures on the connecting portion 122 are provided with two slots, which are defined as a first slot 1221 and a second slot 1222 for ease of description, and both slots penetrate the two circular ring structures, and the angle between the two slots is 90 degrees.

[0055] like Figures 7 and 8 , Figures 10 to 12As shown, in one embodiment, when the connection portion 122 is plugged into the rotating shaft portion 112 so that the folding frame 14 and the supporting frame 13 are on the same horizontal plane, the opening of the first slot 1221 on the connection portion 122 will face the support tube 211, and the first slot 1221 and the locking slot 1121 will be on the same horizontal plane. When the connection portion 122 is plugged into the rotating shaft portion 112 so that the folding frame 14 and the supporting frame 13 form an angle of 90 degrees, the folding frame 14 will drive the first slot 1221 to rotate away from the horizontal plane with the locking slot 1121, and at the same time drive the opening of the second slot 1222 toward the support tube 211, so that the second slot 1222 and the locking slot 1121 are on the same horizontal plane. Furthermore, the base frame 10 further includes a block 15, a base 16 and a plurality of locking springs 17. The block 15 is slidably disposed in the base 16. The locking springs 17 are disposed in the base 16. The locking springs 17 are used to push the block 15 so that the block 15 extends out from the base 16. The base 16 is disposed on the triangular piece 11, and the base 16 is disposed close to the slot so that the block 15 can enter the slot after extending out from the base 16. When the first slot 1221 and the locking slot 1121 are in the same horizontal plane, the block 15 extends out from the base 16 and enters the first slot 1221 and the locking slot 1121, so that the folding frame 14 and the supporting frame 13 are kept in the same horizontal plane, thereby enabling the base frame 10 to have a larger support area to improve the stability of the support assembly 20. When the second slot 1222 and the locking slot 1121 are in the same horizontal plane, the card block 15 extends from the card seat 16 and enters the second slot 1222 and the locking slot 1121, so that the folding frame 14 and the supporting frame 13 maintain an angle of 90 degrees. In this way, the multifunctional dining table 1 can fold the supporting assembly 20 and the bottom frame 10 for easy storage and carrying.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
