Description

Technical Field

[0001] The present invention relates to the technical field of medical device auxiliary equipment, and in particular to a multifunctional body position fixing device for X-ray examination of infants. Background Art

[0002] X-ray examination of infants and young children is an important means of clinical diagnosis in pediatrics, especially for the evaluation of bone development, lung diseases and digestive system abnormalities. For example, chest X-rays can be used to examine orthopedic diseases, lung diseases, mediastinal diseases, etc. When taking a chest X-ray, the patient is required to remain still in a certain position. For infants and young children with poor autonomy, family members or medical staff are often required to assist in fixing the chest X-ray. If the child is small and has low cooperation, the parents may even need to hold the child in their arms. This method not only increases the risk of parents being exposed to radiation, but also leads to poor imaging quality due to inadequate fixation.

[0003] Based on this, the prior art provides a variety of fixing and limiting methods, among which the traditional method mostly uses brackets, mats or restraints for fixing. This method still has the problem of poor fixing effect during use, and requires multiple adjustments, which prolongs the preparation time and reduces the overall shooting efficiency. In order to further improve the fixing and limiting method of standing X-ray shooting of infants and young children, the Chinese invention patent with publication number CN108158603B discloses an anti-motion fixing device for pediatric internal medicine filming, which is provided by setting an annular fixing sleeve on the operating platform, and two arc-shaped splints are arranged on the top surface of the annular fixing sleeve, and a limiting mechanism for driving the movement of one of the arc-shaped splints is arranged on the outside below, so as to fix the upper body of the child; compared with the traditional method, this fixing method has better fixing effect and improved efficiency.

[0004] However, the above device still has the following technical problems: 1. The height of the arc splint cannot be adjusted according to the height of the infant. For young children, the height of the arc splint is too high. On the one hand, it will reduce the comfort of use and increase the anxiety of the infant. On the other hand, the arc splint that is too high will interfere with the picking up and placing of the infant; 2. It is impossible to monitor and control the clamping force of the arc splint, which increases the risk of injury to the infant, and inappropriate clamping force will cause the infant to be anxious and move around, thereby affecting the imaging quality. Summary of the invention

[0005] The present invention aims to provide a multifunctional body position fixation device for X-ray examination of infants and young children, so as to solve the technical problems that the existing fixation devices cannot adjust the height according to the height of infants and young children, resulting in low comfort, poor applicability and easy interference during use.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] A multifunctional body position fixing device for X-ray examination of infants and young children comprises a support platform and a limiting mechanism arranged on the support platform, wherein a cushion is arranged on the support platform; the limiting mechanism comprises a multi-section arc clamp barrel and a driving mechanism, wherein the multi-section arc clamp barrel comprises two fixed shafts arranged side by side and a plurality of groups of arc clamp plates arranged on the fixed shafts and arranged along the height direction of the fixed shafts, wherein each group of arc clamp plates consists of two arc sleeves, wherein the two arc sleeves are respectively rotatably arranged on two fixed shafts arranged side by side, and the driving mechanism is used to drive the plurality of groups of arc clamp plates to open and close; the driving mechanism comprises a fixed column and a plurality of groups of driving components arranged on the fixed column, wherein the fixed column is arranged on the support platform and is located on a side of the arc clamp barrel close to the fixed shaft, wherein the driving components correspond to the arc clamp plates one by one and are used to drive the corresponding arc sleeves to rotate around the fixed shafts to realize opening and closing;

[0008] A controller and a gravity detection module and a height detection module electrically connected to the controller are also provided on the support platform. The gravity detection module is arranged on the seat cushion, and the height detection module is arranged on the fixed column for detecting the height of the top of the head of the infant after sitting up. The driving component is electrically connected to the controller; when the gravity detection module detects a continuous pressure signal within a preset time period, the signal is sent to the controller, and the controller controls the height detection module to detect the height of the infant's head and sends the head height information to the controller. The controller controls the action of the driving component below the head height, and uses the driving component to drive the corresponding arc splint to close to fix the infant, and the arc splint above the infant's head is in an open state.

[0009] Beneficial effects:

[0010] 1. High comfort, strong applicability, and no interference: By setting a multi-section arc clamp barrel, the user can choose the appropriate arc splint to close according to the user's height, and the arc splint above the user's head is in an open state, so that the arc clamp barrel can adapt to different infants and young children. Compared with the prior art that uses arc clamp barrels of the same height for different infants and young children, the present application is more comfortable and has strong applicability; in addition, the multi-section arc splint can limit the user in sections, so that the fixing effect is better, and the problem of infants and young children being affected by activities during shooting is solved. The problem of poor imaging quality; finally, when using this device, the infant needs to be held on the support table and sit on the cushion first, and then the infant's arms are lifted up from both sides, and then the arc-shaped clamp barrel is closed, and the inner wall of the arc-shaped clamp barrel is used to limit the falling of the arms; if the arc-shaped clamp barrel is too high, it is easy to interfere with the operator, making it inconvenient to adjust the posture of the infant, thereby increasing the adjustment time and reducing the shooting efficiency; the arc-shaped splint located on the upper side of the infant's head of the present application is in an open state, providing the operator with a avoidance space, which is convenient for adjusting the posture and taking and placing the baby.

[0011] 2. By setting a gravity detection module on the cushion, when the baby is placed on the cushion, the gravity detection module detects a signal and sends the signal to the controller. The gravity signal is used as a start signal for the height detection module. At this time, the height detection module starts to detect the height of the baby after sitting, so that the controller can accurately control the closing of the corresponding arc splint, so that the measurement accuracy and safety of use are higher; in addition, the present application also sets a preset time period, and only when a continuous signal is detected within this time period will the signal be sent to the controller. The continuous signal indicates that the baby has been sitting stably on the cushion. The above method can further improve the accuracy of the measurement, avoid inaccurate height measurement due to mismeasurement, and then cause the problem of insufficient closing height or too high closing height of the subsequent arc splint.

[0012] 3. By setting up a height detection module, the height of the baby after sitting is automatically detected by the height detection module. After the detection is completed, the signal is sent to the controller. At this time, the controller controls the corresponding drive component to move, and then drives the arc splint to close to fix the upper body of the baby. The gravity detection module and the height detection module of the present application have a sequence. The controller first receives the signal from the gravity detection module and then starts the height detection module. After receiving the signal from the height detection module, the drive component is controlled to move. The problem of triggering the start of the height detection module during the process of placing the baby and causing detection errors can be avoided. In addition, this method can reduce the manual adjustment time of medical staff, improve inspection efficiency, reduce operating steps, and reduce the workload of medical staff.

[0013] Preferably, as an improvement, a flexible protective layer is provided on the inner wall of each arc-shaped sleeve, a clamping force detection module is provided inside the flexible protective layer, and the clamping force detection module is electrically connected to the controller; when the clamping force detection module detects that the clamping pressure reaches a preset value, a signal is sent to the controller, and the controller controls the driving component to stop.

[0014] Beneficial effects:

[0015] 1. Setting a flexible protective layer on the inner wall of the arc sleeve can play a certain buffering role, reduce the discomfort caused by the direct clamping of the hard arc sleeve, and avoid problems such as compression and abrasion caused by direct contact of hard objects with the baby's skin.

[0016] 2. By setting up a clamping force detection module, the clamping pressure of the arc sleeve can be detected to avoid harm to the baby due to excessive clamping force or unstable fixation due to too small clamping force; during use, the arc sleeve gradually closes and contacts the baby. When the pressure generated during contact reaches a preset value, the controller controls the drive component to stop, indicating that the clamping limit effect is best at this time and will not cause a large pressure on the baby, which can improve the comfort of use and reduce the problem of the baby's uneasiness and restlessness due to discomfort.

[0017] 3. Each arc sleeve is provided with a clamping force detection module, and the arc sleeve of the present application is arranged in sections, and different clamping forces can be set according to different parts, thereby better improving the fixation effect and comfort; in addition, different clamping forces can also be adjusted according to different infants and young children, so that it is suitable for different groups of people and can still meet the needs of personalized settings.

[0018] Preferably, as an improvement, the height detection module includes a plurality of infrared sensors, each group of arc-shaped clamps corresponds to an infrared sensor, when the infrared sensor detects a continuous signal within a preset time period, the signal is sent to the controller, and the controller controls the corresponding drive component to operate, while the drive component corresponding to the infrared sensor that does not detect the signal does not operate.

[0019] Beneficial effects:

[0020] 1. When the baby is placed on the cushion, the part below the baby's head will block the infrared sensor. At this time, the infrared sensor sends a signal to the controller, and the controller controls the corresponding arc splint to close. By setting a certain detection time, the infrared sensor can have a higher detection accuracy, avoiding the problem of decreased height measurement accuracy due to accidental blocking during the adjustment of body position.

[0021] 2. The infrared sensor that is higher than the baby will not be blocked, resulting in no signal detection, and the corresponding driving component will not work, so that the arc splint is in an open state; in addition, the unblocked infrared sensor can serve as a certain indicator for the operator, making it convenient to quickly adjust the height of the X-ray machine so that the X-ray machine can be aimed at the baby's chest for shooting.

[0022] Preferably, as an improvement, it also includes several groups of measuring buttons electrically connected to the controller, the several measuring buttons are arranged on the side of the fixed column away from the arc clamp barrel and arranged along the height direction of the fixed column, and each group of measuring buttons corresponds to a group of arc clamps in turn; when the measuring button is pressed, the controller controls the corresponding driving component to act.

[0023] Beneficial effect: The measuring buttons are arranged in sequence in the height direction of the fixed column, so that the measuring buttons act as scale lines. When the baby is placed on the cushion, the operator can quickly determine the measuring button corresponding to the height of his head, and press the measuring buttons in this group and below. After receiving the signal, the controller controls the corresponding driving component to move, and then drives the corresponding arc splint to close.

[0024] Preferably, as an improvement, the arc sleeve is arranged on the fixed shaft through the rotating shaft, one side of the arc sleeve is fixedly connected to the rotating shaft, the rotating shaft is rotatably sleeved on the fixed shaft through a bearing, and a half gear is arranged on the fixed shaft.

[0026] Beneficial effects: the arc sleeve is driven to open and close through the meshing of the rack and the half gear, the driving structure is simple, and maintenance and inspection are convenient; and it is conducive to accurately controlling the opening and closing degree of the arc sleeve, ensuring the stability and safety of infants and young children during the inspection process.

[0028] Beneficial effect: The piston rod of the cylinder is used to push the insertion rod to move forward and backward. When the piston rod stops at a certain position, the insertion rod can be locked, so that the insertion rod cannot move during the shooting process. Then the half gear cannot rotate to engage the rack on the insertion rod, thereby ensuring the stability of the arc sleeve after closing, avoiding the problem of the arc sleeve opening and causing the baby to fall when the baby applies an outward thrust to the arc sleeve, thereby ensuring the safety of use.

[0030] Beneficial effect: A manual control opening and closing method is provided. When the arc sleeve is closed to a suitable position, the rotation of the screw sleeve is stopped and the screw rod can play a locking role. Even if the baby applies outward force to the arc sleeve, the insertion rod is limited by the screw rod. At this time, the half gear cannot rotate the next tooth portion of the meshing rack, that is, the half gear cannot drive the rotating shaft to rotate, thereby ensuring the stability of the arc sleeve after limiting, and avoiding the problem of the baby falling due to the opening of the arc sleeve during filming.

[0043] Embodiment 1

[0044] like Figure 1-2As shown, the multifunctional body position fixing device for X-ray examination of infants and young children comprises a support platform 1 and a limiting mechanism arranged on the support platform 1, and a cushion 111 is arranged on the support platform 1; specifically, the support platform 1 is in the shape of a square table or a round table, and the bottom of the table legs of the support platform 1 are provided with universal wheels 12 for easy displacement, an opening 11 is arranged in the middle of the support platform 1, and the cushion 111 is arranged at the opening 11. When in use, the infant is held to the opening 11, the lower limbs pass through the opening 11 and naturally hang down, and the buttocks sit on the cushion 111; in this embodiment, an annular fixing sleeve 13 is also arranged on the support platform 1, and the through hole on the annular fixing sleeve 13 is aligned with the opening 11 on the support platform 1, and the annular fixing sleeve 13 is made of radiation-proof material, for example, the existing lead clothing material or lead glass, which can protect the lower abdomen of the infant and young children, and at the same time play a preliminary limiting role when the infant is placed on the cushion 111.

[0045] The limiting mechanism includes a multi-section arc-shaped clamp barrel 2 and a driving mechanism, such as Figure 3 As shown, the multi-section arc clamp barrel 2 includes two fixed shafts 22 arranged side by side and a plurality of groups of arc clamps 21 arranged on the fixed shafts 22 and arranged along the height direction of the fixed shafts 22, and the bottom of the fixed shaft 22 is fixed on the annular fixed sleeve 13; this embodiment takes the arrangement of four groups of arc clamps 21 as an example for detailed description, which are divided into the first group, the second group, the third group, and the fourth group from bottom to top, and the width of the first group is greater than that of the other groups. Each group of arc clamps 21 is composed of two arc sleeves 211, and the two arc sleeves 211 are respectively rotatably arranged on two fixed shafts 22 arranged side by side, and the driving mechanism is used to drive the plurality of groups of arc clamps 21 to open and close; specifically, the arc sleeve 211 is arranged on the fixed shaft 22 through the rotating shaft 23, one side of the arc sleeve 211 is integrally formed with the rotating shaft 23, and the rotating shaft 23 is rotatably sleeved on the fixed shaft 22 through a bearing, and a half gear 231 is arranged on the side of the fixed shaft 22 away from the arc sleeve 211.

[0046] like Figure 2 As shown, the driving mechanism includes a fixed column 3 and a plurality of driving components 4 arranged on the fixed column 3. The bottom of the fixed column 3 is provided with an ear plate, which is fixed to the support platform 1 by bolts. In this embodiment, the fixed column 3 is a square column and is located on the side of the arc clamp barrel close to the fixed shaft 22. The driving component 4 corresponds to the arc clamp plate 21 one by one, and is used to drive the corresponding arc sleeve 211 to rotate around the fixed shaft 22 to achieve opening and closing. Specifically, the driving component 4 includes a telescopic member 41 and a plug rod 42 arranged on the power output end of the telescopic member 41. The telescopic member 41 is arranged on the fixed column 3. The plug rod 42 is located between the two fixed shafts 22, and racks 421 are arranged on the left and right sides of the plug rod 42. The rack 421 is used to mesh with the half gear 231 on the rotating shaft 23. When the plug rod 42 moves back and forth, it drives the half gear 231 to rotate, thereby driving the arc sleeve 211 to open and close.

[0047] More preferably, in this embodiment, the telescopic member 41 is a cylinder, the piston rod of the cylinder is fixedly connected to the insertion rod 42, and when the piston rod is extended forward, it drives the insertion rod 42 to move forward, and the rack 421 on the insertion rod 42 engages with the half gears 231 on both sides, and the two half gears 231 rotate in opposite directions to drive the arc sleeve 211 to close; when the piston rod is retracted, it drives the insertion rod 42 to move backward, and the rack 421 on the insertion rod 42 engages with the half gear 231, thereby driving the two half gears 231 to rotate and drive the arc sleeve 211 to open. By utilizing the piston rod of the air cylinder to push the insertion rod 42 to move forward and backward, when the piston rod stops at a certain position, the insertion rod 42 can be locked, so that the insertion rod 42 cannot move during the X-ray film shooting process, and then the half gear 231 cannot rotate to engage the rack 421 on the insertion rod 42, thereby ensuring the stability of the arc sleeve 211 after closing, avoiding the problem of the arc sleeve 211 opening and causing the baby to fall when the baby applies an outward thrust to the arc sleeve 211, thereby ensuring the safety of use.

[0048] like Figure 4 As shown, in this embodiment, a controller 5 and a gravity detection module 51 and a height detection module 52 electrically connected to the controller 5 are also provided on the support platform 1. Specifically, the controller 5 can adopt a PLC controller or a single-chip microcomputer, and the gravity detection module 51 is a pressure sensor or a gravity sensor. In this embodiment, a gravity sensor is preferred; the gravity detection module 51 is arranged on the cushion 111, and the height detection module 52 is arranged on the fixed column 3 for detecting the height of the head of the infant after sitting. The drive component 4 is electrically connected to the controller 5. Specifically, in this embodiment, the controller 5 is electrically connected to the cylinder corresponding to each group of arc splints 21.

[0049] When the gravity detection module 51 detects a continuous pressure signal within a preset time period, the signal is sent to the controller 5. The controller 5 controls the height detection module 52 to detect the height of the infant's head. After the height detection module 52 completes the detection, the head height information is sent to the controller 5. The controller 5 controls the drive component 4 below the head height to move, and uses the drive component 4 to drive the corresponding arc splint 21 to close to fix the infant, and the arc splint 21 above the infant's head is in an open state.

[0050] By setting a gravity detection module 51 on the cushion 111, when the baby is placed on the cushion 111, the gravity detection module 51 detects a signal and sends the signal to the controller 5. The gravity signal is used as a start signal for the height detection module 52. At this time, the height detection module 52 starts to detect the height of the baby after sitting, so that the controller 5 can accurately control the closing of the corresponding arc splint 21, so that the measurement accuracy and safety of use are higher; in addition, the signal is sent to the controller 5 only when a continuous signal is detected within a preset time period. The continuous signal is used to indicate that the baby has been sitting stably on the cushion 111. The above method can further improve the accuracy of the measurement, avoid inaccurate height measurement due to mismeasurement, and then cause the problem of insufficient closing height or too high closing height of the subsequent arc splint 21.

[0051] Specific as Figure 2 As shown, the height detection module 52 includes a plurality of infrared sensors 521, and each group of arc-shaped clamping plates 21 corresponds to an infrared sensor 521. More preferably, the setting height of each infrared sensor 521 is located at two-thirds of the height of the corresponding arc-shaped clamping plate 21. When the infrared sensor 521 detects a continuous signal within a preset time period, the signal is sent to the controller 5. The controller 5 controls the corresponding drive component 4 to operate, while the drive component 4 corresponding to the infrared sensor 521 that does not detect a signal does not operate. During use, after the baby is placed on the cushion 111, the part below the baby's head will block the infrared sensor 521. At this time, the infrared sensor 521 sends a signal to the controller 5, and the controller 5 controls the corresponding arc splint 21 to close; the infrared sensor 521 above the baby will not be blocked, resulting in no signal detection, and the corresponding drive component 4 will not move, so that the arc splint 21 is in an open state; in addition, the unblocked infrared sensor 521 can play a certain indicating role for the operator, which is convenient for quickly adjusting the height of the X-ray machine so that the X-ray machine is aimed at the baby's chest for shooting.

[0052] In this embodiment, a flexible protective layer (not shown in the figure) is arranged on the inner wall of each arc sleeve 211. The flexible protective layer can be made of airbags or silicone. A clamping force detection module 53 is arranged in the flexible protective layer. In this embodiment, the clamping force detection module 53 is a pressure sensor. The flexible protective layer is arranged on the inner wall of the arc sleeve 211, which can play a certain buffering role, reduce the discomfort caused by the direct clamping of the hard arc sleeve 211, and avoid the problems of compression and abrasion caused by the direct contact of hard objects with the baby's skin. Figure 4As shown, the clamping force detection module 53 is electrically connected to the controller 5. When the clamping force detection module 53 detects that the clamping pressure reaches a preset value, a signal is sent to the controller 5, and the controller 5 controls the driving component 4 to stop. The clamping force detection module 53 is arranged to detect the clamping pressure of the arc sleeve 211 to avoid the problem of injury to the baby due to excessive clamping force or unstable fixation due to too small clamping force. During specific use, the arc sleeve 211 gradually closes and contacts the baby. When the pressure generated during the contact reaches a preset value, the controller 5 controls the driving component 4 to stop, indicating that the clamping limit effect is best at this time and will not cause a large pressure on the baby, which can improve the comfort of use and reduce the problem of the baby's uneasiness and restlessness due to discomfort.

[0053] The method of using the multifunctional body position fixation device for infant X-ray examination is as follows:

[0054] Step 1, preparation stage: ensure that all arc splints 21 are in the open state, then hold the baby onto the support platform 1, let the baby's lower limbs pass through the opening 11 on the support platform 1 and hang down naturally, the baby's buttocks sit on the cushion 111, and the lower abdomen is limited by the annular fixing sleeve 13.

[0055] Step 2, gravity detection: After the baby sits on the cushion 111, the gravity detection module 51 detects a signal, and sends a signal to the controller 5 when a continuous pressure signal is detected within a preset time period. For example, when the gravity signal can be detected within 3-5 seconds, it indicates that the baby has sat stably on the cushion 111, and the next step of detection is entered.

[0056] Step 3, height detection: When the controller 5 receives the signal sent by the gravity detection module 51, the height detection module 52 is started. At this time, the baby's upper arm is adjusted synchronously. The operator lifts the baby's upper arm upward from both sides and keeps it unchanged after adjustment. At this time, the height detection module 52 can detect a continuous and stable signal and send the signal to the controller 5; more preferably, after the controller 5 receives the signal sent by the height detection module 52, it can control the height detection module 52 to close while controlling the arc splint 21 to close, or close it after the arc splint 21 is closed, so as to ensure that there is no relevant noise signal when taking X-rays, thereby ensuring the imaging quality.

[0057] Step 4, closing the arc splint 21: After receiving the signal sent by the height detection module 52, the controller 5 controls the corresponding driving component 4 to move, and then drives the arc sleeve 211 to close. During the closing process, the arc sleeve 211 gradually contacts the baby's body to limit it. When the clamping force detection module 53 detects that the clamping force reaches the preset value, it sends a signal to the controller 5. The controller 5 controls the driving component 4 to stop, indicating that the clamping and limiting effect is the best at this time, and no greater pressure will be caused to the baby, thereby achieving the purpose of fixing the baby in an upright position.

[0058] Step 5, adjust the position of the support table 1: after the fixing of the limiting mechanism is completed, move the support table 1 so that the baby is located at the center of the X-ray imaging plate; when the device of the present application is in use, the driving mechanism is located on the left or right side of the X-ray machine, and the X-ray machine is adjusted from the position of the support table 1 to the center of the X-ray imaging plate; Figure 3 Shoot in the direction indicated by the arrow to ensure image quality.

[0059] The multifunctional body position fixation device for X-ray examination of infants provided by the present application can be suitable for infants of different age groups, for example, for infants aged 0-3 years old, the height and width of the arc-shaped clamp barrel can be adjusted according to the height and body shape of the infant, the application range is wide, and the fixation effect and comfort of use are good; in addition, because the height of the arc-shaped clamp barrel corresponds to the height of the infant, it will not cause interference, which is convenient for operators to take and place the infant, and is conducive to reducing preparation and adjustment time, and automatically measures gravity, height, clamping force, etc. during the placement process, which can not only ensure the fixation effect, but also will not reduce the measurement efficiency. Compared with the existing technology, it reduces the fixation adjustment time before shooting, improves the overall operation efficiency, and can also reduce the workload of operators, resulting in significant technical progress.

[0060] Embodiment 2

[0061] The difference between this embodiment and the first embodiment is that Figure 5 As shown, it also includes several groups of measuring buttons 522 electrically connected to the controller 5. Several measuring buttons 522 are arranged on the side of the fixed column 3 away from the arc clamp barrel and arranged along the height direction of the fixed column 3. Each group of measuring buttons 522 corresponds to a group of arc clamps 21 in sequence. When the measuring button 522 is pressed, the controller 5 controls the corresponding driving component 4 to act; by sequentially arranging the measuring buttons 522 in the height direction of the fixed column 3, the measuring buttons 522 play the role of scale lines. The technical solution of this embodiment can be used alone as an alternative to the first embodiment, and can also be used as a backup solution. When it is used as an alternative solution, the operation process is as follows: when the baby is placed on the cushion 111, the operator can quickly determine the measuring button 522 corresponding to the height of the baby's head, press the measuring button 522 of this group and below, and the controller 5 controls the corresponding driving component 4 to act after receiving the signal, thereby driving the corresponding arc clamp 21 to close.

[0062] When the infrared sensor 521 is used as the height detection module 52 to detect the height, the measuring button 522 is used as an inspection component: Specifically, this embodiment also includes a voice module, which is electrically connected to the controller 5. When the controller 5 receives the signal sent by the height detection module 52, it controls the voice module to broadcast the height signal. At this time, the operator can confirm the information. When the detected height does not match the actual height, the operator manually presses the measuring button 522. At this time, after the controller 5 receives the signal of the measuring button 522, it controls the corresponding driving component 4 to start and controls the multiple groups of infrared sensors 521 to turn off. The above technical solution can further improve the accuracy of the measurement, and the height measurement can be manually checked again. If the measurement is inaccurate, it can be corrected by pressing the measuring button 522, thereby ensuring that the multi-section arc clamp barrel 2 is adjusted accordingly according to the height of the baby.

[0063] Embodiment 3

[0064] The difference between this embodiment and the first and second embodiments is that Figure 6-7 As shown, the telescopic member 41 is a screw assembly 6, which includes a screw 61 and a screw sleeve 62 threadedly connected to the screw 61, the screw sleeve 62 is rotatably arranged on the fixed column 3, and the screw 61 is slidably arranged on the fixed column 3 through a limiting assembly; specifically, a penetrating mounting hole 31 is arranged on the fixed column 3, and the mounting hole 31 is a stepped hole in this embodiment, one end of the screw sleeve 62 extends into the large end of the mounting hole 31, and the outer wall of the screw sleeve 62 is rotatably connected to the hole wall of the mounting hole 31, the screw 61 extends into the small end of the mounting hole 31, and a limiting groove 311 is arranged on the side wall of the small end of the mounting hole 31, and a limiting rod 611 matching the limiting groove 311 is arranged on one side of the screw 61, and the limiting rod 611 is slidably connected to the limiting groove 311; when the screw sleeve 62 is rotated, the screw 61 makes a linear motion to extend or retract to the mounting hole 31.

[0065] In this embodiment, one end of the screw 61 close to the arc sleeve 211 is fixedly connected to the insertion rod 42. When the screw sleeve 62 rotates clockwise, it is used to drive the screw 61 to move forward, thereby driving the insertion rod 42 to move forward, and the racks 421 on both sides of the insertion rod 42 mesh with the half gears 231 on both sides, so that the two arc sleeves 211 are gradually closed; when the screw sleeve 62 rotates counterclockwise, it is used to drive the screw 61 to move backward. At this time, the screw 61 drives the insertion rod 42 to move backward, and the half gear 231 meshing with the rack 421 on the insertion rod 42 rotates in the opposite direction, thereby closing the arc sleeves 211 on both sides.

[0066] The present embodiment provides a method of manually controlling the opening and closing, and can realize automatic locking; when the arc sleeve 211 is closed to a suitable position, the rotation of the screw sleeve 62 is stopped, and the screw 61 can play a locking role. Even if the baby applies an outward force to the arc sleeve 211, since the insertion rod 42 is limited by the screw 61, the half gear 231 cannot rotate to the next tooth portion of the meshing rack 421, that is, the half gear 231 cannot drive the rotating shaft 23 to rotate, thereby ensuring the stability of the arc sleeve 211 after being limited, and avoiding the problem of the arc sleeve 211 opening and causing the baby to fall during the filming process.

[0067] Embodiment 4

[0068] The difference between this embodiment and embodiments 1, 2 and 3 is that Figure 8 As shown, the two arc sleeves 211 in the same set of arc splints 21 are asymmetrically arranged, the one with a larger area is the main arc sleeve 2111 , and the one with a smaller area is the auxiliary arc sleeve 2112 .

[0069] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
