[0045] The specific structure of the plastic electric auxiliary lifting equipment will be mainly described below.

[0046] like Figure 1 and Figures 3 to 6 , as shown, a plastic electric auxiliary lifting device includes a seat assembly 100, a folding assembly 200, an electric push rod 300 and a buckle structure 400, the seat assembly 100 includes a seat plate 110 and a backrest 120 rotatably connected to the seat plate 110; the folding assembly 200 is used to support the seat assembly 100; the electric push rod 300 includes a main body 310 and a push rod 320 partially arranged in the main body 310, the main body 310 is arranged on the backrest 120, and the push rod 320 has a push rod head 321, The push rod head 321 is detachably arranged on the folding assembly 200, and the push rod 320 can be axially extended and retracted relative to the main body 310, so that the main body 310 drives the folding assembly 200 to unfold or fold, thereby driving the seat assembly 100 to rise and fall; the buckle structure 400 is used to limit the push rod head 321 of the push rod 320 to the folding assembly 200, or to cancel the limitation of the push rod head 321 of the push rod 320, thereby realizing the detachable setting of the push rod head 321 of the push rod 320 relative to the folding assembly 200.

[0047] When it is necessary to help elderly people, paralyzed patients and other users to stand up, the users cannot stand up directly by themselves, so the push rod 320 is driven to retract axially relative to the main body 310, so that the main body 310 drives the folding assembly 200 to fold, thereby driving the seat assembly 100 to descend. After the seat assembly 100 descends to a suitable position (for example, the seat assembly 100 descends to the lowest point), the user is allowed to sit on the seat plate 110, and then the push rod 320 is driven to extend axially relative to the main body 310, so that the main body 310 drives the folding assembly 200 to unfold, thereby driving the seat assembly 100 to rise, so that the user's center of gravity height rises accordingly, until the user is close to a standing posture, or the user has achieved a standing posture. In addition, when the plastic electric auxiliary lifting device is not used or needs to be moved, the driving push rod 320 is axially retracted relative to the main body 310, so that the main body 310 drives the folding assembly 200 to fold, thereby driving the seat assembly 100 to descend, and cancels the limit of the push rod head 321 by the buckle structure 400, and then the backrest 120 is rotated toward the seat plate 110 to achieve the folding of the backrest 120 relative to the seat plate 110, so that the plastic electric auxiliary lifting device is folded (refer to Fig.14 ), which greatly reduces the space occupied by the plastic electric-assisted lifting equipment, thereby facilitating the storage and transfer of the plastic electric-assisted lifting equipment.

[0048] Specifically, if the buckle structure 400 does not cancel the limit on the push rod head 321, the push rod head 321 cannot rotate relative to the folding assembly 200, and then the backrest 120 cannot rotate relative to the seat plate 110 under the limit of the electric push rod 300, so the backrest 120 cannot be folded relative to the seat plate 110.

[0049] In this embodiment, the buckle structure 400 is disposed on the folding assembly 200 .

In this embodiment, the middle portion of the first connecting arm 221 and the middle portion of the second connecting arm 222 are hinged.

[0060] refer to Figure 1 , Figure 2 and Figure 8 The first sliding end 2212 is connected to the first slider 2213, the second sliding end 2222 is connected to the second slider 2223, a first slide groove 211 is opened at the top of the base plate 210, and a second slide groove 111 is opened at the bottom of the seat plate 110. The first slider 2213 is slidably clamped in the first slide groove 211, and the first slider 2213 can slide along the first slide groove 211 to move away from or approach the second hinged end 2221. The second slider 2223 is slidably clamped in the second slide groove 111, and the second slider 2223 can slide along the second slide groove 111 to move away from or approach the first hinged end 2211.

[0061] Specifically, when the push rod 320 is axially extended relative to the main body 310, the first slider 2213 drives the first sliding end 2212 along the first slide groove 211 away from the second hinged end 2221, and the second slider 2223 drives the second sliding end 2222 along the second slide groove 111 away from the first hinged end 2211, thereby realizing the unfolding of the folding component 200; when the push rod 320 is axially retracted relative to the main body 310, the first slider 2213 drives the first sliding end 2212 along the first slide groove 211 to approach the second hinged end 2221, and the second slider 2223 drives the second sliding end 2222 along the second slide groove 111 to approach the first hinged end 2211, thereby realizing the folding of the folding component 200.

[0062] refer to Figure 1 and Figure 8 The number of the cross arms 220 is two, and the two cross arms 220 are arranged between the bottom plate 210 and the seat plate 110. Specifically, the two cross arms 220 support the seat assembly 100 more reliably. Specifically, the number of the first slide groove 211 and the second slide groove 111 is also two, which cooperate with the two cross arms 220.

[0063] refer to Figure 2 and Figure 8 The folding assembly 200 further includes a connecting rod 230 , wherein the connecting rod 230 is disposed between the two first connecting arms 221 , and the connecting rod 230 is disposed between the two second connecting arms 222 .

[0064] refer to Figures 4 to 6 and Fig.10 and Fig.16 The buckle structure 400 includes an extension portion 410, a shaft 420, a buckle 430 and a torsion spring 440. The extension portion 410 is arranged on the base plate 210. The extension portion 410 is provided with an arc groove 411. The shaft 420 passes through the extension portion 410. The buckle 430 is rotatably arranged on the shaft 420. The torsion spring 440 is sleeved on the shaft 420. One end of the torsion spring 440 is abutted against the base plate 210, and the other end of the torsion spring 440 is abutted against the buckle 430. The arc groove 411 is used to accommodate the push rod head 321. The buckle 430 is used to limit the push rod head 321 to the arc groove 411, or to release the limit on the push rod head 321.

[0065] refer to Figure 6 and Fig.14 The push rod head 321 is cylindrical and is disposed at the end of the push rod 320 . In the present embodiment, there are two push rod heads 321 , which are located at both sides of the end of the push rod 320 .

[0066] refer to Figure 4 and Figures 9 to 16The buckle 430 has a limiting end 431 and a free end 432. The limiting end 431 is rotatably set on the shaft 420. A top block 116 is set at the bottom of the seat plate 110. The top block 116 is used to push against the free end 432 to make the buckle 430 rotate in a direction away from the push rod head 321, so that the limiting end 431 cancels the limit on the push rod head 321.

[0067] Specifically, when the folding assembly 200 is unfolded, the seat plate 110 is away from the bottom plate 210, so that the top block 116 is away from the free end 432, so that the buckle 430 is reset under the action of the torsion spring 440 and rotates in the direction close to the push rod head 321, thereby causing the limit end 431 of the buckle 430 to limit the push rod head 321; when the folding assembly 200 is folded, the seat plate 110 is close to the bottom plate 210, so that the top block 116 is close to and abuts against the free end 432, so that the buckle 430 rotates in the direction away from the push rod head 321, so that the limit end 431 cancels the limit on the push rod head 321. After the limit end 431 cancels the limit on the push rod head 321, the backrest 120 can be rotated to drive the electric push rod 300 to rotate relative to the seat plate 110, thereby realizing the folding of the backrest 120.

[0068] That is to say, when the folding assembly 200 is folded and the seat plate 110 drops to the lowest point, the limiting end 431 of the buckle 430 will cancel the limitation on the push rod head 321. Conversely, when the folding assembly 200 is unfolded, the seat plate 110 rises, the buckle 430 is reset under the action of the torsion spring 440, and the limiting end 431 of the buckle 430 limits the push rod head 321.

[0070] refer to Figure 4 ,and Figures 11 to 16 The hook structure 500 includes a hook 510 and an elastic member 520 . The hook 510 is rotatably connected to the extension portion 410 . The hook 510 has a hanging end 511 and an adjusting end 512 . The elastic member 520 is disposed on the bottom plate 210 , and the elastic member 520 abuts against the adjusting end 512 . The hanging end 511 is used to hang the seat plate 110 .

[0071] Specifically, when the push rod head 321 is limited in the arc groove 411, the push rod 320 presses the adjusting end 512 to make the hanging end 511 tilt up, thereby canceling the hanging end 511 hanging on the seat plate 110; when the push rod head 321 leaves the arc groove 411, the push rod 320 does not press the adjusting end 512, and the adjusting end 512 tilts up under the action of the elastic member 520 to press the hanging end 511 downward, thereby the hanging end 511 hangs the seat plate 110.

[0072] In this embodiment, the elastic member 520 is a spring; there are two elastic members 520 , and the two elastic members 520 abut against the adjusting end 512 , which can more reliably apply elastic force to the adjusting end 512 of the hook 510 .

[0073] In this embodiment, since the hook structure 500 is provided, when the push rod head 321 is limited by the limiting end 431 of the buckle 430, the end of the push rod 320 presses the adjusting end 512 of the hook structure 500, and at this time, the hanging end 511 does not hang the seat plate 110; when the push rod head 321 leaves the arc groove 411, the end of the push rod 320 is no longer pressing the adjusting end 512 of the hook structure 500, and at this time, the hanging end 511 hangs the seat plate 110. That is to say, when the plastic electric auxiliary lifting device is folded as a whole, the push rod head 321 has left the circular arc groove 411, so that the hanging end 511 must hang the seat plate 110, and the seat plate 110 is fixed relative to the bottom plate 210; when the electric push rod 300 is extended and retracted, the push rod head 321 presses the adjustment end 512 of the hook structure 500 in the circular arc groove 411, so that the hanging end 511 must not hang the seat plate 110, thereby ensuring that the seat plate 110 can be raised and lowered relative to the bottom plate 210. In addition, when the backrest 120 switches from folding to unfolding, since the seat plate 110 is fixed relative to the bottom plate 210 when the backrest 120 is folded, the circular arc groove 411 located on the bottom plate 210 does not change its position relative to the backrest 120 and the electric push rod 300, thereby ensuring that after the backrest 120 is unfolded, the push rod head 321 of the electric push rod 300 can just be accommodated in the circular arc groove 411.

[0074] Specifically, after the folding assembly 200 is folded and the hanging end 511 of the hook structure 500 hangs the seat plate 110, the seat plate 110 is fixed relative to the bottom plate 210, such as Fig.11 Further, after the folding assembly 200 is folded, the seat plate 110 is fixed relative to the bottom plate 210, and the backrest 120 is folded relative to the seat plate 110, the entire plastic electric auxiliary lifting device is folded, as shown. Fig.14 shown.

Specifically, the plastic electric auxiliary lifting device of the utility model can be used in a bathtub. The suction cup 600 adsorbed on the bottom of the bathtub can ensure the stability of the plastic electric auxiliary lifting device and prevent the user sitting on the seat plate 110 from falling.

[0076] refer to Figure 1 There are multiple suction cups 600, and the multiple suction cups 600 are arranged at intervals at the bottom of the base plate 210.

[0077] refer to Fig.17 The suction cup 600 is provided with an exhaust hole 610. The suction cup 600 is provided with an exhaust hole 610. When the user sits on the seat plate 110, the exhaust hole 610 contacts the bottom of the bathtub and is blocked by the bottom of the bathtub. At this time, the suction cup 600 can be reliably adsorbed on the bottom of the bathtub. When the user stands up from the seat plate 110, the exhaust hole 610 is separated from the bottom of the bathtub, and the suction cup 600 is connected to the outside air through the exhaust hole 610. The suction cup 600 has no adsorption effect, so that the plastic electric auxiliary lifting equipment can be easily picked up.
