Description

Technical Field

[0001] This application relates to the field of medical care equipment, and particularly to an assisted getting-up device. Background Art

[0002] Currently, for the elderly with relatively heavy weight, it is very difficult for a helper to lift them up after they fall to the ground. In order to facilitate the getting-up of people with inconvenient mobility, a getting-up device is generally used as an assisted getting-up device, which can be used in nursing homes, community home care services, and families with disabled elderly.

[0003] The getting-up device in the related art includes a support chassis, a getting-up frame, and a positioning frame. The support chassis is horizontally placed on the bed surface. The getting-up frame is hingedly connected to one side of the top surface of the support chassis. The positioning frame is located between the getting-up frame and the support chassis. A plurality of positioning grooves are provided on the support chassis along its length direction for accommodating one end of the positioning frame. One end of the positioning frame is hingedly connected to the bottom wall of the getting-up frame.

[0004] When the patient needs to get up, the getting-up frame can be adjusted to a horizontal state. Then, the helper places the horizontally placed support chassis and the getting-up frame under the patient's back, so that the support chassis lies flat on the ground. At the same time, the helper helps the patient to sit up, then rotates the getting-up frame to a suitable angle, and finally lapps the positioning frame in a suitable positioning groove to stably fix the getting-up frame in an inclined state, thereby supporting the patient to sit up through the getting-up frame. At this time, the helper can assist the patient to get up.

[0005] In the process of using the above getting-up device in the related art, after the helper manually helps the patient to sit up, the getting-up frame needs to be opened and positioned at a suitable angle, and the operation process is complex, time-consuming and laborious. Summary of the Invention

[0006] In order to help the helper to assist the patient to get up conveniently, this application provides an assisted getting-up device.

[0007] The assisted getting-up device provided by this application adopts the following technical solution:

[0008] An assisted getting-up device includes a main body, a back bracket, and a bracket. The back bracket and the bracket are both arranged on the side wall of the main body through a connecting component. The back bracket and the bracket are both used to fit on the ground. The side wall of the main body located at the back bracket is used to fit the patient's buttocks. The back bracket is used to support the patient's back. An angle adjustment component for driving the bracket to rotate is provided on the main body.

[0009] By adopting the above technical solution, when the patient falls to the ground, the helper first places the back bracket between the patient's back and the ground, then bends the patient's legs, fits the side wall of the main body to the patient's buttocks, connects the back bracket to the main body by using the connection component, fixes the bracket to the side wall of the main body by using the connection component, and finally drives the bracket to rotate on the ground by using the angle adjustment component. Then the main body and the back bracket rotate synchronously with the bracket. At this time, the bracket supports the center of gravity of the patient by rotation. When the appropriate angle is reached, stop rotating the bracket, and finally complete the assistance for the patient to get up; the getting-up assistance device composed of the above structure can automatically assist the patient to get up, is simple to operate, replaces manual assistance for the patient to sit up, and saves time and effort.

[0010] In a specific feasible implementation, the connection component includes an insertion block, an elastic clamping block and a rubber sleeve. The insertion block is arranged on the side walls of the back bracket and the bracket. A slot for the insertion block to insert is provided on the side wall of the main body. The elastic clamping block is arranged on the wall of the slot. A clamping slot matched with the elastic clamping block is provided on the side wall of the insertion block. The rubber sleeve is sleeved on the side wall of the insertion block, and the side wall of the rubber sleeve fits with the wall of the slot.

[0011] By adopting the above technical solution, during installation, insert the insertion block into the slot. When the insertion block touches the elastic clamping block, the elastic clamping block deforms so as to completely insert the insertion block into the slot. Until the insertion block is completely inserted into the slot, the elastic clamping block aligns with the clamping slot. At this time, the elastic clamping block loses the external resisting force. Then, under the action of its own elastic restoring force, the side wall of the elastic clamping block abuts against the side wall of the clamping slot so as to limit and fix the insertion block in the slot; at the same time, by using the good wear resistance effect of the rubber sleeve, the insertion block is fixed in the slot, and finally the detachable connection between the back bracket and the bracket and the main body is realized; this connection method has a simple structure and is convenient for disassembly and assembly.

[0012] In a specific feasible implementation, the bracket includes a passive fixing frame and an active power moving frame. The passive fixing frame is fixedly arranged on the side wall of the main body. The passive fixing frame and the back bracket are arranged opposite to each other. The active power moving frame is rotatably arranged on the side wall of the main body, and the angle adjustment component drives the active power moving frame to rotate.

[0013] By adopting the above technical solution, support the passive fixing frame and the active power moving frame on the ground so that the main body, the passive fixing frame and the active power moving frame can stably support the center of gravity of the patient. Then use the angle adjustment component to drive the active power moving frame to rotate, so that the included angle between the active power moving frame and the passive fixing frame gradually decreases. At this time, the main body drives the patient to get up gradually through the back bracket.

[0014] In a specific feasible implementation, the passive fixing frame includes two arc-shaped fixing rods, and the two arc-shaped fixing rods are arranged on the side wall of the main body far from the back bracket through the connection component.

[0015] By adopting the above technical solution, as the main power moving frame rotates, it is supported on the ground by two arc-shaped fixed rods, so that the main machine and the back bracket drive the patient to get up stably.

[0016] In a specific feasible implementation, the main power moving frame includes two arc-shaped moving rods, and the two arc-shaped moving rods respectively correspond to the two side end walls of the main machine. The arc-shaped moving rods are arranged on the end walls of the main machine, and the two arc-shaped moving rods respectively correspond to the two arc-shaped fixed rods. The outer arc surfaces of the arc-shaped moving rods and the arc-shaped fixed rods are both used to face the ground.

[0017] By adopting the above technical solution, when the patient lies flat on the back bracket on the ground, the included angle between the arc-shaped moving rod, the arc-shaped fixed rod and the relative side wall of the main machine is the largest. When it is necessary to assist the patient to get up, the angle adjustment component is used to drive the two arc-shaped moving rods to rotate towards the arc-shaped fixed rod. At this time, the main machine drives the back bracket and the arc-shaped fixed rod to rotate away from the ground, and at the same time, it is supported on the ground by the arc-shaped fixed rod, and the included angle between the arc-shaped moving rod and the arc-shaped fixed rod gradually decreases, so that the back bracket and the main machine can stably support the center of gravity of the patient. Finally, as the arc-shaped moving rod rotates, it assists the patient to get up stably.

[0018] In a specific feasible implementation, rollers are rotatably connected to the ends of the arc-shaped moving rod and the arc-shaped fixed rod away from the main machine, and the peripheral wall of the roller is used to abut against the ground.

[0019] By adopting the above technical solution, the setting of the rollers enables the arc-shaped moving rod and the arc-shaped fixed rod to rotate stably on the ground, which helps to reduce the friction between the ends of the arc-shaped moving rod and the arc-shaped fixed rod and the ground, and is convenient for quickly assisting the patient to get up, saving time and effort.

[0020] In a specific feasible implementation, the angle adjustment component includes a double-headed motor and two rotating arms. The double-headed motor is arranged on the inner side wall of the main machine, and the two rotating arms respectively correspond to the two side end walls of the main machine. The rotating arms are rotatably connected to the end walls of the main machine. The driving shaft of the double-headed motor extends out of the end wall of the main machine and is connected to the rotating arm. The arc-shaped moving rod is detachably connected to the free end of the rotating arm through a connecting component.

[0021] By adopting the above technical solution, after the arc-shaped moving rod is fixedly installed on the rotating arm by using the connecting component, the double-headed motor is started, and the double-headed motor drives the two rotating arms to rotate synchronously, thereby driving the arc-shaped moving rod to rotate, realizing the angle adjustment of the main machine. This adjustment method has a simple structure and is convenient to operate.

[0022] In a specific feasible implementation, a charging seat is embedded in the side wall of the host. The charging seat is used to provide electrical energy for the dual-head motor, and a charging interface is provided on the side wall of the charging seat; a control panel is provided on the side wall of the host, and a display screen for displaying the power of the charging seat is provided on the control panel. A first button for controlling the forward rotation of the drive shaft of the dual-head motor is provided on the control panel, and a second button for controlling the reverse rotation of the drive shaft of the dual-head motor is provided on the control panel.

[0023] By adopting the above technical solution, the setting of the charging interface facilitates the charging seat to be connected to the power supply through a wire for charging and storing electricity; the setting of the display screen enables the user to conveniently check the power of the charging seat at any time, so as to charge the charging seat in time when the power of the charging seat is insufficient; the first button and the second button are used to control the operation of the dual-head motor, so as to drive the rotating arm to rotate, facilitating the operator's operation.

[0024] In a specific feasible implementation, the back bracket includes two support rods, and the two support rods are oppositely arranged on the side wall of the host. The support rods are detachably connected to the side wall of the host through a connecting component. Arc-shaped support plates are provided on the opposite side walls of the two support rods, and the two arc-shaped support plates are used to support the patient's back.

[0025] By adopting the above technical solution, the support rods are fixed on the side wall of the host through the connecting component, so as to support the patient's back through the two arc-shaped support plates. When the host rotates, the host drives the arc-shaped support plates to rotate synchronously through the support rods, thereby realizing assisting the patient to get up.

[0026] In a specific feasible implementation, an arc-shaped supporting surface is provided on the side wall of the host where the back bracket is located, and a plurality of anti-slip lines are provided on the arc-shaped supporting surface.

[0027] By adopting the above technical solution, since the side wall of the host where the back bracket is located is used to abut against the patient's buttocks, the setting of the arc-shaped supporting surface facilitates better fitting between the side walls of the patient's buttocks; the setting of the anti-slip lines helps to increase the friction between the patient's buttocks and the side wall of the host, so that when the host rotates, the host can stably drive the patient to get up.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Place the back bracket between the patient's back and the ground, fit the side wall of the host to the patient's buttocks, then connect the back bracket and the bracket to the host using the connecting component, and finally use the angle adjustment component to drive the bracket to rotate on the ground. Then the host and the back bracket rotate synchronously with the bracket. At this time, the center of gravity of the patient is supported by the rotation of the bracket. Stop rotating the bracket when reaching the appropriate angle, and finally complete the assistance for the patient to get up, ultimately realizing automatically assisting the patient to get up, replacing manual assistance for the patient to sit up, with simple operation, saving time and effort;

[0030] 2. Insert the insertion block into the slot, so that the elastic clamping block is clamped in the clamping groove. At the same time, utilize the good friction resistance effect of the rubber sleeve to fix the insertion block in the slot, and finally realize the detachable connection between the back bracket and the bracket and the host. This connection method has a simple structure and is convenient for disassembly and assembly;

[0031] 3. Utilize the rollers to make the arc-shaped moving rod and the arc-shaped fixed rod rotate stably on the ground, which helps to reduce the friction between the ends of the arc-shaped moving rod and the arc-shaped fixed rod and the ground, and is convenient for quickly assisting the patient to get up, saving time and effort.

[0045] The following further describes the present application in detail with reference to the attached drawings. Figure 1-12 The present application is further described in detail below.

[0046] The embodiment of the present application discloses an auxiliary getting-up device.

[0047] Embodiment 1

[0048] Referring to Figure 1 , the auxiliary getting-up device includes a main body 1, a back bracket and a bracket. The back bracket 2 is fixedly arranged on the top wall of the main body 1. The bracket is composed of a passive fixing bracket and a main power moving bracket. The passive fixing bracket is fixedly arranged on the bottom wall of the main body 1. The passive fixing bracket and the back bracket 2 are arranged opposite to each other. The main power moving bracket is arranged on the end wall of the main body 1. An angle adjustment assembly 6 for driving the main power moving bracket to rotate is arranged on the main body 1. Both the back bracket 2 and the main power moving bracket are arranged on the side wall of the main body 1 through a connecting assembly 7. Both the passive fixing bracket and the main power moving bracket are used for abutting against the ground; in this embodiment, the main body 1 is located on the side wall of the back bracket 2 for fitting against the patient's buttocks, and the back bracket 2 is used for supporting the patient's back.

[0049] When the patient falls to the ground, the helper first places the back bracket 2 between the ground and the patient's back; secondly, the helper bends the patient's legs so as to place the main body 1 on the ground and fit it against the patient's buttocks, and at the same time the passive fixing bracket is suspended above the ground; then the helper uses the connecting assembly 7 to fixedly connect the back bracket 2 and the main body 1, and uses the connecting assembly 7 to fixedly install the main power moving bracket on the side wall of the main body 1;

[0050] Finally, the angle adjustment component 6 is used to drive the active power movement frame to rotate, so that the main machine 1, the back bracket 2 and the passive fixing frame rotate and stably support the center of gravity of the patient. At the same time, when the active power movement frame and the passive fixing frame rotate, the free ends of the active power movement frame and the passive fixing frame support on the ground, so that the active power movement frame can support the center of gravity of the patient by rotation. When the patient completes the standing-up action, the driving of the active power movement frame to rotate is stopped, and finally the automatic assistance for the patient to stand up is realized, so as to replace the manual assistance for the patient to stand up, saving time and effort.

[0051] In this embodiment, since both the back bracket 2 and the bracket are arranged on the side wall of the main machine 1, the detachable connection between the back bracket 2, the bracket and the main machine 1 is realized, which is convenient for carrying. And during use, it is convenient to place the back bracket 2 and the main machine 1 in appropriate positions.

[0052] Refer to Figure 1 , the back bracket 2 includes two support rods 201 and two arc-shaped support plates 202. The support rods 201 are vertically arranged on the top wall of the main machine 1. The two support rods 201 are arranged oppositely. The two arc-shaped support plates 202 respectively correspond to the two support rods 201 one by one, and the two arc-shaped support plates 202 are respectively arranged on the opposite side walls of the two support rods 201. The arrangement of the two arc-shaped support plates 202 is used to support the patient's back, so as to stably assist the patient to stand up.

[0053] Refer to Figure 1 , the top wall of the main machine 1 is provided with an arc-shaped supporting surface 101, which helps the side wall of the main machine 1 located at the back bracket 2 to better fit with the patient's buttocks. In this embodiment, a plurality of anti-slip lines 102 are arranged on the arc-shaped supporting surface 101. The arrangement of the anti-slip lines 102 helps to increase the friction between the patient's buttocks and the side wall of the arc-shaped supporting surface 101 of the main machine 1, so that the main machine 1 can stably support the patient's buttocks.

[0054] Refer to Figure 1 , the passive fixing frame includes two arc-shaped fixing rods 3, and both of the two arc-shaped fixing rods 3 are arranged on the side wall of the main machine 1 far away from the back bracket 2 through the connecting component 7.

[0055] The active power movement frame includes two arc-shaped movement rods 4. The two arc-shaped movement rods 4 respectively correspond to the two end walls of the main machine 1 one by one. The arc-shaped movement rods 4 are arranged on the end wall of the main machine 1 through the connecting component 7, and the angle adjustment component 6 drives the arc-shaped movement rods 4 to rotate.

[0056] In this embodiment, the two arc-shaped moving rods 4 correspond to the two arc-shaped fixed rods 3 one by one. The outer arc surfaces of the arc-shaped moving rods 4 and the arc-shaped fixed rods 3 are both used to face the ground. The free ends of the arc-shaped moving rods 4 and the arc-shaped fixed rods 3 are both rotatably connected with rollers 5, and the peripheral walls of the rollers 5 are used to abut against the ground. When in use, after placing the back bracket 2 between the patient's back and the ground, the arc-shaped moving rods 4 and the arc-shaped fixed rods 3 are respectively installed on the main body 1 by using the connecting assembly 7. At this time, the included angles between the arc-shaped moving rods 4, the arc-shaped fixed rods 3 and the main body 1 tend to be 180°.

[0057] When the angle adjusting assembly 6 is used to drive the two arc-shaped moving rods 4 to rotate, the arc-shaped moving rods 4 drive the main body 1, the back bracket 2 and the arc-shaped fixed rods 3 to rotate, so that the included angles between the arc-shaped moving rods 4, the arc-shaped fixed rods 3 and the main body 1 gradually decrease, facilitating the support of the patient's center of gravity. While the arc-shaped moving rods 4 and the arc-shaped fixed rods 3 are rotating, the rollers 5 on the arc-shaped moving rods 4 and the arc-shaped fixed rods 3 roll on the ground. The setting of the rollers 5 helps to reduce the friction between the arc-shaped moving rods 4 and the arc-shaped fixed rods 3 and the ground, and helps the angle adjusting assembly 6 to drive the arc-shaped fixed rods 3 to rotate, so as to quickly support the patient's center of gravity and facilitate assisting the patient to get up.

[0058] Referring to Figure 1 and Figure 2 , the angle adjusting assembly 6 includes a double-headed motor 61 and two rotating arms 62. The main body 1 is arranged in a shell shape, and the inside of the main body 1 is hollow. The body of the double-headed motor 61 is arranged on the inner side wall of the main body 1. The two drive shafts of the double-headed motor 61 correspond to the two rotating arms 62 one by one. The two rotating arms 62 are respectively rotatably connected to the two side end walls of the main body 1. The drive shafts of the double-headed motor 61 extend out of the end wall of the main body 1 and are fixedly connected to the rotating arms 62. In this embodiment, the two rotating arms 62 correspond to the two arc-shaped moving rods 4 one by one. The end of the arc-shaped moving rod 4 far from the roller 5 is connected to the rotating arm 62 through the connecting assembly 7. Starting the double-headed motor 61, the double-headed motor 61 drives the rotating arm 62 to rotate, and then drives the arc-shaped moving rod 4 to rotate. This driving method has a simple structure and is convenient for adjustment.

[0059] Referring to Figure 1 and Figure 3 , there are three groups of the connecting assemblies 7 in this embodiment. The first group of the connecting assembly 7 corresponds to the support rod 201, the second group of the connecting assembly 7 corresponds to the arc-shaped fixed rod 3, and the third group of the connecting assembly 7 corresponds to the arc-shaped moving rod 4.

[0060] One set of connecting components 7 includes an insertion block 71, an elastic clamping block 72 and a rubber sleeve 73. The insertion blocks 71 in each set of connecting components 7 are respectively arranged on the side walls of the support rod 201, the arc-shaped fixing rod 3 and the arc-shaped moving rod 4. A slot 74 for inserting the insertion block 71 is provided on the side wall of the main body 1. In this embodiment, the insertion block 71 and the slot 74 are in concave-convex fit. The elastic clamping block 72 is arranged on the wall of the slot 74. The elastic clamping block 72 is made of rubber. A clamping groove 75 for cooperating with the elastic clamping block 72 is provided on the side wall of the insertion block 71. The rubber sleeve 73 is arranged on the side wall of the insertion block 71.

[0061] During installation, insert the insertion block 71 into the slot 74. When the insertion block 71 abuts against the elastic clamping block 72, as the insertion block 71 is inserted, the elastic clamping block 72 deforms to insert the insertion block 71 into the slot 74. When the insertion block 71 is completely inserted into the slot 74, the elastic clamping block 72 aligns with the clamping groove 75. Then, under the action of its own elastic restoring force, the elastic clamping block 72 is inserted into the clamping groove 75, realizing the limit of the insertion block 71 in the slot 74. In addition, when the insertion block 71 is completely inserted into the slot 74, the side wall of the rubber sleeve 73 fits against the wall of the slot 74. Utilizing the good wear resistance of the rubber sleeve 73, the insertion block 71 is stably fixed in the slot 74, thereby realizing the fixed connection between the support rod 201 or the arc-shaped moving rod 4 and the main body 1.

[0062] In this embodiment, in the connecting component 7 corresponding to the arc-shaped moving rod 4, the slot 74 is arranged on the side wall of the free end of the rotating arm 62. Insert the insertion block 71 into the slot 74 on the side wall of the rotating arm 62 to realize the fixed connection between the arc-shaped moving rod 4 and the rotating arm 62. The connection method constituted by the above structure is simple and convenient to operate.

[0063] Refer to Figure 2 and Figure 4 , a charging seat 8 is embedded in the side wall of the main body 1. The charging seat 8 is detachably connected to the side wall of the main body 1. The charging seat 8 is used to provide electric energy for the double-headed motor 61. The bottom wall of the charging seat 8 is provided with two charging interfaces 9. One of the charging interfaces 9 is for inserting a charging connector to facilitate charging and storing electricity of the charging seat 8. The other charging interface 9 cooperates with the vehicle-mounted power supply to be compatible with the vehicle-mounted charging of the charging seat 8.

[0064] In this embodiment, a handle 14 is further provided on the side wall of the charging seat 8 to facilitate personnel to pick up and place the charging seat 8 and the main body 1, which is convenient and practical.

[0065] In addition, two opposite rubber support blocks 15 are provided on the side wall of the main body 1 away from the charging seat 8. The rubber support blocks 15 are provided to stably support the main body 1 on the ground when the main body 1 is placed at the position of the patient's buttocks.

[0066] Refer to Figure 4 andFigure 5 On one side wall of the main body 1, there is also a control panel 10 provided with a display screen 11 for displaying the power of the charging base 8, so that the user can pay attention to the power of the charging base 8 at any time and charge the charging base 8 in time.

[0067] On the control panel 10, there is a first button 12 for controlling the forward rotation of the drive shaft of the double-headed motor 61 to control the lifting operation of the auxiliary lifting device; on the control panel 10, there is a second button 13 for controlling the reverse rotation of the drive shaft of the double-headed motor 61 to control the lowering of the auxiliary lifting device; the settings of the first button 12 and the second button 13 facilitate the helper to control the operation of the auxiliary lifting device according to the actual situation, which is convenient and practical.

[0068] On the control panel 10, there are also a reset button 25 and an emergency stop button 26. The reset button 25 is used to control the reset of the drive shaft of the double-headed motor 61; the setting of the emergency stop button 26 facilitates the helper to press the emergency stop button 26 to control the emergency stop of the double-headed motor 61 according to the actual scenario.

[0069] The implementation principle of Embodiment 1 is as follows: When the patient falls to the ground, the helper first places the arc-shaped support plate 202 between the ground and the patient's back; secondly, the helper bends the patient's legs so as to place the main body 1 on the ground and fit it with the patient's buttocks; then, the insertion holes on the support rod 201, the arc-shaped fixing rod 3 and the arc-shaped moving rod 4 are inserted into the slot 74 in sequence. By engaging the elastic clamping block 72 in the clamping slot 75 and making the side wall of the rubber sleeve 73 fit with the slot wall of the slot 74, the plug 71 is fixed in the slot 74, thereby realizing the fixed connection between the support rod 201 and the arc-shaped fixing rod 3 and the main body 1, as well as the fixed connection between the arc-shaped moving rod 4 and the rotating arm 62.

[0070] Finally, start the double-headed motor 61. The double-headed motor 61 drives the two rotating arms 62 to rotate, and then drives the two arc-shaped moving rods 4 to rotate. Then, the main body 1, the arc-shaped support plate 202 and the arc-shaped fixing rod 3 rotate synchronously with the rotation of the arc-shaped moving rod 4 to drive the patient to get up. At the same time, the rollers 5 on the arc-shaped moving rod 4 and the arc-shaped fixing rod 3 roll on the ground, and the angle between the arc-shaped moving rod 4 and the arc-shaped fixing rod 3 gradually decreases. Finally, the patient's center of gravity is supported by the rotation of the arc-shaped moving rod 4, the arc-shaped fixing rod 3, the main body 1 and the arc-shaped support plate 202. Until the patient is assisted to get up to an appropriate angle, stop driving the arc-shaped moving rod 4 to rotate, and finally complete the patient's lifting assistance, replacing manual manual assistance for the patient to get up, saving time and effort and having high assistance efficiency.

The two swing arms 18 respectively correspond to the two side end walls of the main body 1. The swing arms 18 are rotatably connected to the end walls of the main body 1. A linkage rod 17 is rotatably arranged inside the main body 1. The two ends of the linkage rod 17 respectively pass through the two side end walls of the main body 1 and are respectively fixedly connected to the two swing arms 18. A driving gear 171 is fixedly sleeved on the linkage rod 17. A driven gear 172 is engaged with one side of the driving gear. The driven gear 172 is rotatably connected to the inner side wall of the main body 1 through a rotating shaft 173. One end of the rotating shaft 173 extends out of the end wall of the main body 1, and a docking port 174 that cooperates with the crank 16 is provided on the end wall of the rotating shaft 173; the two swing arms 18 respectively correspond to the two arc-shaped moving rods 4. The arc-shaped moving rods 4 are connected to the swing arms 18 through a connecting assembly 7.

[0074] When in use, the helper inserts the crank 16 into the docking port 174 of the rotating shaft 173, and then rotates the crank 16. The crank 16 drives the rotating shaft 173 to rotate, so that the driven gear 172 drives the driving gear 171 to rotate, thereby driving the two swing arms 18 to rotate through the linkage rod 17, and finally realizing the synchronous rotation of the two arc-shaped moving rods 4 to assist the patient to get up.

[0075] Embodiment 3

[0076] Reference Figure 9 The difference between this embodiment and Embodiment 1 lies in the different structure of the connecting assembly 7. The support rod 201 and the arc-shaped fixing rod 3 are both connected to the main body 1 through the connecting assembly 7. The arc-shaped moving rod 4 is also connected to the rotating arm 62 through the connecting assembly 7.

[0077] Reference Figure 10 、 Figure 11 and Figure 12 Taking the connecting assembly 7 provided on the arc-shaped moving rod 4 as an example, the connecting assembly 7 includes a connecting block 19 and two clamping plates 20. The connecting block 19 is arranged on the side wall of the rotating arm 62. A connecting groove 21 for inserting the connecting block 19 is provided on the side wall of the arc-shaped moving rod 4. The connecting blocks 19 in the other two groups of connecting assemblies 7 are all arranged on the side wall of the main body 1.

[0078] In this embodiment, two clamping plates 20 are oppositely arranged in the connection groove 21. After the connection block 19 is inserted into the connection groove 21, the connection block 19 is located between the two clamping plates 20. The middle parts of the side walls of the two clamping plates 20 are rotatably connected to the groove wall of the connection groove 21 through rotating shafts 173. Fixed hooks 22 are provided on the side walls of the two clamping plates 20 facing the connection block 19, and connection rings 23 for the fixed hooks 22 to hook are provided on both side walls of the connection. A rotating member 24 is provided in the connection groove 21 to drive the side walls of the two clamping plates 20 where the fixed hooks 22 are located to rotate towards the side wall of the connection block 19.

[0079] Since the clamping plate 20 is rotatably connected to the groove wall of the connection groove 21, the rotating member 24 is used to drive the two clamping plates 20 to rotate towards the side wall of the connection block 19, so as to hook the fixed hook 22 to the connection ring 23, thereby realizing the fixation of the connection block 19 in the connection groove 21, which helps to prevent the connection block 19 from disengaging from the connection groove 21, and thus realizes the installation of the arc-shaped moving rod 4.

[0080] The rotating member 24 includes a linkage wedge block 241, a first wedge block 242, a second wedge block 243, a screw 244, a nut 245 and a limiting block 246. The first wedge block 242 is located above the connection block 19 and between the two clamping plates 20. The linkage wedge block 241 is slidably connected to the groove wall of the connection groove 21 through a sliding member. The first wedge block 242 is arranged on the side wall of the linkage block away from the connection block 19. The first wedge block 242 and the linkage wedge block 241 are integrally formed. The sliding direction of the linkage wedge block 241 and the first wedge block 242 is the same as the depth direction of the connection groove 21. The cross-sectional area of the linkage wedge block 241 decreases from bottom to top, and the cross-sectional area of the first wedge block 242 decreases from top to bottom. The second wedge block 243 is located on one side of the first wedge block 242, and the second wedge block 243 and the first wedge block 242 are slidably connected through a dovetail block.

[0081] The axial direction of the screw 244 is perpendicular to the sliding direction of the first wedge block 242. A through hole 247 is provided on the side wall of the arc-shaped supporting rod 201. One end of the screw 244 passes through the through hole 247 and extends into the connection groove 21, and the screw 244 is rotatably connected to the side wall of the second wedge block 243 away from the first wedge block 242. The nut 245 is rotatably arranged on the outer wall of the arc-shaped supporting rod 201, and the nut 245 is threadedly connected to the screw 244. The limiting block 246 is arranged on the hole wall of the through hole 247. A limiting groove for the limiting block 246 to slide is provided on the side wall of the screw 244 along its own axial direction. Due to the cooperation of the limiting block 246 and the limiting groove, it plays a guiding and limiting role in the sliding of the screw 244. When the nut 245 is rotated, the screw 244 is driven to slide along its own axial direction, and the second wedge block 243 can be pushed to slide towards the first wedge block 242 through the screw 244.

[0082] With the sliding of the second wedge block 243, the second wedge block 243 pushes the first wedge block 242 to slide in the direction of the connecting block 19, and the linkage wedge block 241 slides synchronously with the first wedge block 242. Since the cross-sectional area of the linkage wedge block 241 decreases from low to high, as the linkage wedge block 241 slides, the linkage wedge block 241 pushes the two clamping plates 20 away from each other at the ends away from the fixed hook 22, so that the ends of the two clamping plates 20 close to each other at the fixed hook 22, and the fixed hook 22 can hook the connecting ring 23 on the side wall of the connecting block 19, and finally the fixing of the connecting block 19 in the connecting groove 21 is realized, so as to fixedly connect the arc-shaped moving rod 4 and the rotating arm 62.

[0083] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
