[0002] A fixed electric displacement machine is an electric auxiliary device used in medical, rehabilitation and other fields. It is installed in a fixed manner and uses electricity as the core driving force (power output is achieved through components such as motors and electric push rods) to drive loads (such as medical devices, rehabilitation devices, patient support components, etc.) to achieve precise displacement and position adjustment (such as height, horizontal distance, angle, extension length, etc.) in space and to stabilize them.

[0003] Existing fixed electric displacement machines typically lack a locking mechanism for the rotating rod. When the rotating rod reaches the designated position, patient contact or external force can cause the rotating rod to rotate unexpectedly, reducing the stability of the device and increasing safety hazards.

[0004] Therefore, it is necessary to propose a fixed electric displacement machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fixed electric displacement machine to solve the problem that the rotating rod has no locking structure, and when the rotating rod rotates to the designated position, the patient or external force will touch the rotating rod and cause it to rotate unexpectedly, which reduces the stability of the device and increases safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed electric displacement machine, including a fixed rod, a rotating rod rotatably connected to the top of the fixed rod, a connecting rod rotatably connected to the top of the rotating rod, an adjusting rod slidably connected to one side of the connecting rod, an electric push rod rotatably connected to one side of the outer circumference of the rotating rod, a mounting frame fixedly connected to the bottom surface of the connecting rod, and the top of the push rod of the electric push rod rotatably connected to the mounting frame; A fixed disc is fixedly connected to the bottom of the rotating rod, and sliding columns are slidably connected to both sides of the fixed disc.

[0007] Preferably, two square frames are fixedly connected to the outer periphery of the bottom of the rotating rod, and a seven-branch rod is rotatably connected between the square frames. A V-shaped frame is rotatably connected to the bottom end of the seven-branch rod, and the bottom end of the V-shaped frame is rotatably connected to the top of the sliding column.

[0008] Preferably, the top of the adjusting rod is provided with a plurality of insertion holes evenly distributed, and the connecting rod is provided with an insertion rod, which passes through the connecting rod and is inserted into any of the insertion holes.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model, and should not be construed as limiting this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the description of this utility model, it should be understood that the terminology used is for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] This utility model provides, for example Figures 1-3 The fixed electric displacement machine shown includes a fixed rod 1, a rotating rod 2 rotatably connected to the top of the fixed rod 1, a connecting rod 22 rotatably connected to the top of the rotating rod 2, an adjusting rod 24 slidably connected to one side of the connecting rod 22, an electric push rod 21 rotatably connected to one side of the outer circumference of the rotating rod 2, and a mounting frame 23 fixedly connected to the bottom surface of the connecting rod 22. The top of the push rod of the electric push rod 21 is rotatably connected to the mounting frame 23. When the patient needs to be moved, one end of the adjusting rod 24 is lowered to a suitable position, thereby connecting the patient to the device via a strap. During adjustment, the electric push rod 21 is opened, and the electric push rod 21 pulls the connecting rod 22 downward by retracting the push rod. The connecting rod 22 rotates along the top of the rotating rod 2, and the rotation of the connecting rod 22 causes one end of the adjusting rod 24 to descend. Once the adjusting rod 24 has descended to the designated position, subsequent work can proceed.

[0019] It should be noted that the top of the adjusting rod 24 is evenly provided with multiple insertion holes 25, and the connecting rod 22 is provided with an insertion rod 26. The insertion rod 26 passes through the connecting rod 22 and is inserted into any insertion hole 25. When the insertion rod 26 is pulled out and the length of the adjusting rod 24 is adjusted, the adjusting rod 24 is moved and moves within the connecting rod 22. After it is moved to a suitable position, the insertion rod 26 is passed through the connecting rod 22 and inserted into the corresponding insertion hole 25 to complete the fixation of the connecting rod 22 and the adjusting rod 24.

[0020] In this invention, the adjustable length of the adjusting rod 24 and the ability of the adjusting rod 24, the insertion hole 25, and the rotating rod 2 to rotate in any direction break through the spatial limitations of the device, flexibly cover different parts of the patient's body, and are convenient to use. Furthermore, the length of the adjusting rod 24 can be adjusted according to the patient's height and body shape to better fit the patient.

[0021] Furthermore, a fixed disc 41 is fixedly connected to the bottom of the rotating rod 2, and sliding columns 45 are slidably connected to both sides of the fixed disc 41. A second gear disc 4 is fixedly connected to the bottom end of the sliding column 45 and is slidably connected to the outer periphery of the rotating rod 2. A first gear disc 11 is fixedly connected to the top of the fixed rod 1, and the first gear disc 11 and the second gear disc 4 are connected in a cooperative manner. After the rotating rod 2 rotates to a suitable position, the sliding column 45 moves downward. The movement of the sliding column 45 causes the second gear disc 4 to slide on the rotating rod 2. After the second gear disc 4 moves and contacts the first gear disc 11, the teeth on it engage, thereby fixing the rotating rod 2 and ensuring that the rotating rod 2 will not rotate during operation.

[0022] It should be noted that two square frames 42 are fixedly connected to the bottom outer periphery of the rotating rod 2. A seven-branch rod 43 is rotatably connected between the square frames 42. A V-shaped frame 44 is rotatably connected to the bottom end of the seven-branch rod 43. The bottom end of the V-shaped frame 44 is rotatably connected to the top of the sliding column 45. After the rotating rod 2 is rotated to the appropriate position, the seven-branch rod 43 is pressed down. The seven-branch rod 43 rotates between the square frames 42. The seven-branch rod 43 drives the top end of the V-shaped frame 44 to rotate at the bottom end of the seven-branch rod 43. At the same time, it drives the V-shaped frame 44 to move downward. The V-shaped frame 44 drives the sliding column 45 to move downward. The top end of the sliding column 45 rotates at the bottom end of the V-shaped frame 44.

[0023] In this invention, after the rotating rod 2 is rotated to any direction, pressing the seven-piece rod 43 will lock the rotating rod 2 in place, preventing accidental rotation of the rotating rod 2 due to patient movement or external force, thus improving the stability of the device and reducing safety hazards.

[0024] In this utility model, a connecting frame 27 is fixedly connected to the bottom end of the adjusting rod 24. The connecting frame 27 is equipped with a hanging bracket 3 through a snap-fit ​​structure. Hooks 31 are fixedly connected to both sides of the hanging bracket 3. The connecting frame 27 helps to connect the hanging bracket 3 to the adjusting rod 24. A snap-fit ​​component is installed in the middle of the hanging bracket 3. The snap-fit ​​component is a common technology in the prior art and will not be described in detail here. The hanging bracket 3 can be quickly disassembled and assembled through the snap-fit ​​component. The hooks 31 help to connect the strap to the hanging bracket 3.

[0025] In this utility model, a plurality of support rods 12 are rotatably connected to the bottom outer periphery of the fixed rod 1; when installing the device, the support rods 12 are rotated, and the bottom end of the support rods 12 contacts the ground. The fixed rod 1 and the bottom surface of the support rods 12 are installed to the ground by bolts to complete the fixation.

[0026] It should be noted that limit posts 46 are fixedly connected to both sides of the top surface of the second gear disk 4, and the limit posts 46 are slidably connected to the fixed disk 41; the limit posts 46 provide assistance for the up and down movement of the second gear disk 4.
