The adjusting member also has a pressing part on the side facing the fixing member. As the adjusting member rotates, the pressing part can press the fixing member downward, thereby driving the frame assembly downward.

[0009] In a specific embodiment of this utility model, the frame assembly includes a frame body, a first outer shell, and a second outer shell. The frame body is sleeved on the central rod. The cross plate and the support plate are both disposed on the frame body. The fixed handle is disposed on the frame body. The lifting handle and the adapter are both rotatably connected to the frame body. The first outer shell and the second outer shell are respectively disposed on both sides of the frame assembly and surround the frame assembly. Part of the lifting handle extends out from the area surrounded by the first outer shell and the second outer shell, and part of the fixed handle extends out from the area surrounded by the first outer shell and the second outer shell.

[0010] In a specific embodiment of this utility model, the lifting handle includes a rotating part, an abutting part, and a gripping part. The rotating part is rotatably connected to the frame assembly, the gripping part is connected to the rotating part and extends out of the frame assembly, and the abutting part is located on the side of the rotating part facing the adapter and abuts against the outer periphery of the adapter.

[0011] In a specific embodiment of this utility model, the abutting part is a pulley, which is rotatably connected to the rotating part and abuts against the outer periphery of the adapter.

The mounting component passes through the mounting seat and the bottom of the center rod in sequence to connect the center rod to the mounting seat.

[0015] Compared with the prior art, the advantages of this utility model embodiment of a downward-pressing lifting device are as follows: This utility model's lifting device, by incorporating an adapter, allows for lifting even when the lifting handle is positioned above the fixed handle. Specifically, due to the adapter, pressing the lifting handle rotates the adapter, which then presses one end of the push plate. Because a first spring is located below the push plate, consistently providing an upward force, the other end of the push plate lifts up, pushing the cross plate, frame assembly, and support plate upward relative to the center rod. The fixed assembly prevents the frame assembly and other structures from sliding down after pressing the lifting handle is stopped. Furthermore, the lifting handle, adapter, and push plate return to their original positions under the action of the first spring, ready for the next lifting action. Since the lifting handle is positioned above the fixed handle, it allows for easier user control compared to when it's below. In some situations, the user can even apply force to the lifting handle using their foot, making it even more convenient to use. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0020] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] like Figures 1-5 As shown, a downward-pressing lifting device according to an embodiment of this utility model includes: a central rod 1, a frame assembly 2, a support plate 3, a first spring 4, a pusher 5, a fixing assembly 6, a lifting handle 7, a fixing handle 8, and an adapter 9; the frame assembly 2 is sleeved on the central rod 1 and has a transverse connecting plate 21 inside and a support plate 3 outside; the first spring 4 and the pusher 5 are located inside the frame assembly 2 and are both sleeved on the central rod 1, one end of the first spring 4 abuts against the bottom of the frame assembly 2, and the other end abuts against the pusher 5, the side of the pusher 5 away from the first spring 4 abuts against the transverse connecting plate 21; the fixing assembly 6 is disposed on the frame. The frame assembly 2 is located inside the frame assembly 2 and is fitted onto the central rod 1. It is used to control the frame assembly 2 to slide down along the central rod 1. The fixed handle 8 is located on the frame assembly 2. The lifting handle 7 is rotatably connected to the frame assembly 2 and is located above the fixed handle 8. The adapter 9 is rotatably connected to the inside of the frame assembly 2. The part of the lifting handle 7 that extends into the inside of the frame assembly 2 abuts against one side of the adapter 9. The other side of the adapter 9 abuts against the top surface of one end of the push plate 5. As the lifting handle 7 rotates downward, the adapter 9 can rotate downward and squeeze the push plate 5, causing the push plate 5 to tilt downward, thereby driving the cross plate 21 and the frame assembly 2 to move upward. In this embodiment, the lifting device, by setting an adapter 9, allows the lifting function to be performed even when the lifting handle 7 is positioned above the fixed handle 8. Specifically, due to the adapter 9, pressing the lifting handle 7 causes the rotating handle 7 to rotate, which in turn presses one end of the push plate 5. Since a first spring 4 is located below the push plate 5 and constantly provides an upward force to the push plate 5, the other end of the push plate 5 will tilt upward, thereby pushing the horizontal connecting plate 21, the frame assembly 2, and the support plate 3 relative to the center rod 1. When the lifting handle 7 is moved upwards, the frame assembly 2 and other structures will not slide down under the action of the fixing component 6 after the pressing of the lifting handle 7 is stopped. The lifting handle 7, the adapter 9 and the push plate 5 can return to their original positions under the action of the first spring 4 to perform the next lifting action. Since the lifting handle 7 is set above the fixing handle 8, the user can control the lifting device with less effort compared to when it is set below the fixing handle 8. In some cases, the user can even apply force to the lifting handle 7 with the ball of their foot, making it more convenient to use.

[0023] like Figures 1-4 As shown, in order to control the locking of the support plate 3, the fixing component 6 includes a fixing member 61, a second spring 62 and a third spring 63. The side of the frame component 2 is provided with a first mounting port 22. The fixing member 61, the second spring 62 and the third spring 63 are all sleeved on the center rod 1. One end of the second spring 62 abuts against the cross plate 21 and the other end abuts against the fixing member 61. One end of the third spring 63 abuts against the side of the fixing member 61 away from the second spring 62 and the other end abuts against the top of the frame component 2. One end of the fixing member 61 extends into the first mounting port 22. The elastic force applied by the second spring 62 to the fixing member 61 is greater than the elastic force applied by the third spring 63 to the fixing member 61. Specifically, since one end of the fastener 61 is limited by the first mounting port 22, the fastener 61 is in an inclined state under the action of the second spring 62 and the third spring 63. Therefore, the friction between the fastener 61 and the center rod 1 can be balanced with the gravity of the frame assembly 2 and other structures, so that the frame assembly 2 and the support plate 3 can be stably set in a fixed position.

[0024] like Figures 1-4As shown, in order to achieve rapid descent of the frame assembly 2 and the support plate 3, a button 10 and a fourth spring 11 are also included. The top of the frame assembly 2 has a second mounting port 23, which is correspondingly set with the other end of the fixing member 61. The button 10 is slidably connected to the second mounting port 23. One end of the fourth spring 11 is connected to the other end of the fixing member 61, and the other end of the fourth spring 11 is connected to the button 10. By pressing the button 10, under the action of the fourth spring 11, the friction between the fixing member 61 and the center rod 1 can be quickly changed, thereby achieving rapid descent of the frame assembly 2 and the support plate 3.

[0025] like Figures 1-6 As shown, in order to facilitate the stable descent of the frame assembly 2 and the support plate 3, an adjusting member 12 and a connecting member 13 are also included. The connecting member 13 is sleeved on the central rod 1 and is located between the third spring 63 and the fixing member 61. The top surface of the connecting member 13 abuts against the third spring 63. One end of the connecting member 13 has a protrusion 131 at its bottom, which extends toward the fixing member 61 and abuts against the fixing member 61. The adjusting member 12 is hinged to the other end of the connecting member 13, and part of the adjusting member 12 extends out of the frame assembly 2. The adjusting member 12 also has a pressing part 121 on the side facing the fixing member 61. As the adjusting member 12 rotates, the pressing part 121 can press the fixing member 61 to move downward, thereby driving the frame assembly 2 to move downward. When no pressure is applied to the adjusting member 12, the fixing member 61 and the adjusting member 12 can be reset under the action of the second spring 62 and the third spring 63.

[0026] like Figures 1-4 As shown, in order to protect the frame assembly 2 and the various structures inside the frame assembly 2, the frame assembly 2 includes a frame body 24, a first outer shell 25 and a second outer shell 26. The frame body 24 is sleeved on the central rod 1. The cross plate 21 and the support plate 3 are both provided on the frame body 24. The fixed handle 8 is provided on the frame body 24. The lifting handle 7 and the adapter 9 are both rotatably connected to the frame body 24. The first outer shell 25 and the second outer shell 26 are respectively provided on both sides of the frame assembly 2 and surround the frame assembly 2. Part of the lifting handle 7 extends out from the area surrounded by the first outer shell 25 and the second outer shell 26, and part of the fixed handle 8 extends out from the area surrounded by the first outer shell 25 and the second outer shell 26.

[0027] like Figure 4 and Figure 7 As shown, in a particular embodiment, the frame 24 has a first mounting hole 241, the cross plate 21 has a second mounting hole 211, the center rod 1 passes through the first mounting hole 241 and the second mounting hole 211 in sequence, and a stabilizing member 14 is provided in the gap between the first mounting hole 241 and the center rod 1 and the gap between the second mounting hole 211 and the center rod 1. The stabilizing member 14 is used to prevent the center rod 1 from swaying relative to the first mounting hole 241 and the second mounting hole 211.

[0028] In one particular embodiment, the frame 24, the fixed handle 8, and the cross plate 21 are integrated as one unit.

[0029] like Figure 4 and Figure 8 As shown, in order to facilitate the control of the rotation of the lifting handle 7, the lifting handle 7 includes a rotating part 71, an abutting part 72 and a gripping part 73. The rotating part 71 is rotatably connected to the frame assembly 2. The gripping part 73 is connected to the rotating part 71 and extends out of the frame assembly 2. The abutting part 72 is located on the side of the rotating part 71 facing the adapter 9. The abutting part 72 is a pulley. The pulley is rotatably connected to the rotating part 71 and abuts against the outer periphery of the adapter 9.

[0030] like Figure 1 As shown, for ease of use, a base 15 is also included, with the bottom of the center rod 1 located on the base 15.

[0031] like Figure 1 and Figure 9 As shown, for easy carrying, the top surface of the base 15 has a groove 151, and the support plate 3 is located at the bottom of the frame assembly 2 and is adapted to the shape of the groove 151. As the frame assembly 2 moves upward along the central rod 1, the support plate 3 can slide out of the groove 151.

[0032] like Figure 9 As shown, for ease of assembly, the base 15 includes a mounting plate 152, a mounting seat 153, and a mounting component 154. The mounting seat 153 is located on the top surface of the mounting plate 152, and the top surface of the mounting seat 153 has a mounting groove 1531. The bottom side of the center rod 1 has a connecting hole, and the bottom of the center rod 1 is inserted into the mounting groove 1531. The mounting component 154 passes through the mounting seat 153 and the bottom of the center rod 1 in sequence to connect the center rod 1 to the mounting seat 153.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
