Medical staff must take corresponding isolation measures according to the type of transmission route of the source of infection.
[0003] The curtain-type screen realizes the winding of the screen through the sliding track arranged on the ceiling, which is relatively convenient, but it is necessary to install the track on the ceiling in advance, and the later installation is more cumbersome. The vertical screen occupies a large area and is not easy to carry and store. The traditional medical screen is not convenient to disassemble the screen cloth, and the screen cloth is easy to get dirty after long-term use, which is not conducive to the hygiene and beauty of the medical screen. Summary of the Utility Model
[0004] The utility model aims to overcome the disadvantages of the existing vertical screen that occupies a large area and is not easy to carry and store, and the traditional medical screen that is not convenient to disassemble the screen cloth, and the screen is easy to get dirty after long-term use, which is not conducive to the hygiene and beauty of the medical screen.
[0005] A medical multifunctional folding screen is proposed, which includes a frame for supporting a winding component, a winding component for quick replacement, a locking component for preventing the winding component from reversing, a rotating seat for assisting the rotation of the winding component, and a base for moving the frame. There are three groups of the frames, and the three groups of frames are hinged to each other. Grooves are opened inside each group of frames, and the winding component is vertically arranged inside the grooves of the frames. The locking component is located above the winding component and connected to the frame, and the winding component is clamped on the locking component. Two groups of bases are arranged at the bottom of each group of frames, and the two groups of bases are respectively located on both sides of the frame. The two groups of bases are both connected to the frame.
[0006] In the technical solution of the present utility model, after the screen is used, the fourth frame can be manually pushed towards the first frame. When the side walls of the first frame, the second frame, the third frame, and the fourth frame come into contact with each other, the hook can be rotated clockwise until the groove at the end of the hook catches the protrusion on the side plate of the fourth frame. At this time, the first frame, the second frame, the third frame, and the fourth frame can be fixed. After the groove at the end of the hook catches the protrusion on the side plate of the fourth frame, the three frames can be rotated around the hinge point as the center, so that the three frames overlap into one group. At this time, the floor area of the screen can be greatly reduced. At the same time, universal wheels are provided at the bottom of the frame. Therefore, after the first frame, the second frame, the third frame, and the fourth frame are retracted and fixed by the hook, they can be moved through the universal wheels. The curtain cloth and the winding drum are fixed on the locking assembly and the rotating seat by clamping. Therefore, when the curtain cloth needs to be replaced, only the groove on the first frame needs to be opened to take out the winding assembly, and then a new winding drum and curtain cloth can be replaced to solve the problems in the technical background that the floor area of the vertical screen is large, it is not easy to carry and store, the traditional medical screen is not convenient to disassemble the screen cloth, and the screen is easy to get dirty after long-term use, which is not conducive to the hygiene and beauty of the medical screen.
[0007] Preferably, in the technical solution of the present utility model, a hook is connected to the side plate of each group of frames. After the screen is used, the first frame, the second frame, the third frame, and the fourth frame can be retracted. When the side walls of the first frame, the second frame, the third frame, and the fourth frame come into contact with each other, a hook can be selected to connect and fix the first frame, the second frame, the third frame, and the fourth frame together to prevent the first frame, the second frame, the third frame, and the fourth frame from spreading and being unable to be transported when the screen is moved.
[0008] Preferably, in the technical solution of the present utility model, the frame includes a first frame, a second frame, a third frame, a fourth frame, and a hinge rod. The first frame and the fourth frame are respectively vertically arranged on both sides of the second frame and the third frame, and the first frame, the second frame, the third frame, and the fourth frame are all connected by hinge rods. A groove is opened inside the first frame, and the locking assembly is vertically arranged in the groove inside the first frame. Both ends of the hinge rod are connected to the first frame, the second frame, the third frame, and the fourth frame by hinge means. Therefore, when the first frame, the second frame, the third frame, and the fourth frame need to be unfolded, the frame can be directly pulled apart to extend the extraction distance of the curtain cloth to ensure that the external line of sight can be completely blocked after the curtain cloth is extracted. The frame used is made of stainless steel, which is light, easy to transport, and easy to wipe and disinfect.
[0009] For the optimization of the technical solution of the present utility model, the winding assembly includes a winding drum and a curtain cloth. The curtain cloth is wound around the winding drum and one end of the curtain cloth is adhered to the winding drum. The top end of the winding drum is clamped on the ratchet wheel of the locking assembly. A buckle is provided at the end of the curtain cloth and is connected to the curtain cloth. After the curtain cloth is drawn out, the end of the curtain cloth can be clamped on the fourth frame through the buckle, thereby blocking the line of sight through the curtain cloth.
[0010] For the optimization of the technical solution of the present utility model, the locking assembly includes a housing, a push rod, a disc spring, a ratchet tooth, a rotating cylinder, a ratchet wheel and a torsion spring. The push rod is vertically slidably arranged at the top of the housing, and the bottom end of the push rod is connected to the ratchet tooth. The disc spring is horizontally arranged at the central position inside the housing. The rotating cylinder is rotatably arranged inside the housing and covers the outside of the disc spring, and both ends of the disc spring are respectively clamped on the housing and the rotating cylinder. The ratchet wheel is horizontally arranged at one end of the rotating cylinder and is connected to the rotating cylinder. The ratchet tooth is located on one side of the ratchet wheel and is rotatably connected to the housing. The torsion spring is located at one end of the ratchet tooth and is sleeved on the fixed shaft of the ratchet tooth, and both ends of the torsion spring are respectively clamped on the ratchet tooth and the housing. After the curtain cloth is drawn out from the winding drum, the ratchet tooth will catch the ratchet wheel to prevent reverse rotation driven by the disc spring. After the screen is used up, the push rod can be pressed. At this time, the disc spring can drive the winding drum to reverse, and when the winding drum reverses, the screen can be wound around the winding drum again.
[0011] For the optimization of the technical solution of the present utility model, the base includes a box body, a pressure rod, a fixed shell, a guide rod, a guide box, a clamping block, a spring, a pull rope and a fixing component. The fixed shell is vertically arranged inside the box body. The guide rod is vertically fixed at the central position inside the fixed shell. The pressure rod is horizontally arranged inside the fixed shell and is slidably connected to the guide rod. There are two groups of guide boxes, which are respectively located on both sides of the guide rod and are both connected to the box body. Inside each guide box, a clamping block and a spring are slidably arranged, and the spring is horizontally arranged on one side of the clamping block. One end of each clamping block is connected to a pull rope, and the other ends of the two pull ropes are both connected to the pressure rod. The fixing component is located on one side of the box body and is connected to the box body. The fixed shell is fixed inside the box body through the clamping block, and the universal wheel is fixedly connected to the lower part of the fixed shell. Therefore, when it is necessary to pull out the universal wheel, the pressure rod can be pressed and then the universal wheel can be pulled out from the inside of the box body. After the screen is moved to the required position through the universal wheel, the universal wheel can be retracted into the inside of the box body again through the pressure rod.
[0012] For the optimization of the technical solution of the present utility model, the fixing assembly includes a fixing rod, a tension spring and a fixing pin. There are two groups of fixing rods, both of which are arranged on one side of the box body and are hinged to the box body, and the two groups of fixing rods are connected to each other. The fixing pin is horizontally arranged on one side of the box body, and one end of the fixing pin passes through the box body and is clamped inside the fixing rod. The tension spring is sleeved on the fixing pin, and the two ends of the tension spring are respectively connected to the fixing pin and the box body. After the screen is moved to the required position and the universal wheels are retracted into the box body through the pressure rod, the fixing rod can be screwed out from the box body. After the length direction of the fixing rod is parallel to the ground, the fixing rod can support the screen to prevent the screen from tipping over during use.
[0013] For the optimization of the technical solution of the present utility model, universal wheels are further arranged inside the box body, and the universal wheels are vertically connected to the fixing shell. After the screen is fixed by the hook, the universal wheels can be used for movement, and after the screen is moved, the universal wheels can be fixed in position to prevent the screen from moving (the universal wheels can adopt the M2-4646-445S4 universal double-brake casters of Taizhou Mingshun Caster Manufacturing Co., Ltd.).
[0014] The beneficial effects of the present utility model compared with the prior art are as follows:
[0015] After the present utility model finishes using the screen, the fourth frame can be manually pushed to move towards the first frame until the side walls of the first frame, the second frame, the third frame and the fourth frame are in contact with each other. Then, the catch can be manually rotated. After the groove at the end of the catch is stuck on the protrusion on the side plate of the fourth frame, the three frames can be rotated around the hinge point as the center, so that the three frames overlap into one group. At this time, the floor area of the screen can be greatly reduced, and when the curtain needs to be replaced, the baffle on the groove of the first frame can be opened, and then the winding drum and the curtain can be taken out, which is convenient for replacing and cleaning the curtain.

Specific embodiments
[0036] Next, the technical solutions in the embodiments of the present invention will be described in detail in conjunction with the attached Figure 1-19 drawings in the embodiments of the present invention.
[0037] As Figure 1-5 shown, a medical multi - functional folding screen includes a frame 1 for supporting the reel assembly 2, a reel assembly 2 for quick replacement, a locking assembly 3 for preventing the reel assembly 2 from rotating in reverse, a rotating seat 4 for assisting the rotation of the reel assembly 2, and a base 5 for moving the frame 1. There are three groups of frames 1, and the three groups of frames 1 are hinged to each other. Therefore, all three groups of frames 1 can rotate 360 degrees around the hinge point. Therefore, after the three groups of frames 1 are fully unfolded, the patient's hospital bed can be wrapped from three directions.
[0038] As Figure 1-5 shown, a groove is vertically opened inside each group of frames 1, and the reel assemblies 2 are vertically arranged inside the grooves of the three groups of frames 1. Therefore, after the three groups of frames 1 are fully unfolded, the curtain cloth 22 on the three reel assemblies 2 can be pulled out, and then buckled to the outer wall of the frame 1 through a buckle. After the curtain cloth 22 of the three reel assemblies 2 is pulled out and fixed to the outer wall of the frame 1 through the buckle, the curtain cloth 22 can completely block the line of sight from three directions. The locking assembly 3 is horizontally arranged above the reel assembly 2 and is fixedly connected to the inner wall of the frame 1 by screws.
[0039] As Figure 1-5As shown, the top of the winding component 2 is clamped with the locking component 3. Therefore, when the winding component 2 rotates forward to facilitate the extraction of the curtain cloth 22, the winding component 2 will synchronously drive the locking component 3 to rotate. Then, the locking component 3 will lock the winding component 2 to prevent the winding component 2 from rotating in reverse. After the curtain cloth 22 is used up, the locking component 3 can drive the winding component 2 to rotate in reverse, and when the winding component 2 rotates in reverse, the curtain cloth 22 can be retracted again. The rotating seat 4 is horizontally arranged below the winding component 2 and is fixedly connected to the frame 1 by screws, and the rotating seat 4 is clamped with the winding component 2.
[0040] As Figure 1-5 shown, when the winding component 2 rotates forward or backward, it will rotate through the rotating seat 4. There are two groups of bases 5, and they are both arranged below the frame 1. Two groups of bases 5 are arranged below each group of frames 1, and the two groups of bases 5 are respectively located on both sides of the frame 1 and are both connected to the frame 1. Therefore, when the screen is opened or retracted, the base 5 can support the frame 1 to prevent the frame 1 from coming into direct contact with the ground. Inside each group of bases 5, there is a universal wheel 7 (the universal wheel 7 is an existing product, and the specific model is: M2-4646-445S4 universal double-brake caster of Taizhou Mingshun Caster Manufacturing Co., Ltd.).
[0041] As Figure 1-5 shown, when it is necessary to move the frame 1, the universal wheel 7 can be pulled out from the inside of the box body 51 and then the frame 1 can be moved through the universal wheel 7. After the frame 1 is moved to the required position, the universal wheel 7 can be retracted into the inside of the base 5 again to prevent the universal wheel 7 from moving. A fixing component 6 is arranged on one side of the base 5, and the fixing component 6 is hinged on the base 5. After the frame 1 is fully opened, the fixing component 6 can be opened to support the frame 1 to prevent the frame 1 from tipping over.
[0042] As Figure 1-5 shown, the frame 1 includes a first frame 11, a second frame 12, a third frame 13, a fourth frame 14 and a hinge rod 15. The first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 are arranged in a row, and the second frame 12 and the third frame 13 are adjacent to each other and are both vertically arranged inside the first frame 11 and the fourth frame 14. The first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 are all connected by the hinge rod 15. There are two groups of hinge rods 15, and they are vertically arranged in the middle of the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14.
[0043] As Figure 1-5As shown, both groups of the articulated rods 15 are articulated to the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14. Therefore, when needed, the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 can be fully opened through the articulated rods 15 until the length directions of the articulated rods 15 are parallel. After the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 are opened, the articulated rods 15 can support the curtain cloth 22 of the winding assembly 2 to prevent the curtain cloth 22 from being concave inward.
[0044] As Figure 1-5 shown, when the frame 1 is retracted, the articulated rods 15 can be tightened into the grooves preset on both sides of the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14. Therefore, the side walls of the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 can be in contact, and then the rotating hook 16 can be rotated to connect and fix the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14. The rotating hook 16 is horizontally arranged on one side of the frame 1, and one end of the rotating hook 16 is rotatably connected to the side wall of the frame 1. Therefore, the rotating hook 16 can be rotated. A protrusion is adhesively connected to one side of the fourth frame 14 where the rotating hook 16 is located. After the groove at the front end of the rotating hook 16 hooks the protrusion, the frame 1 can be fixed.
[0045] As Figure 6-8 shown, the winding assembly 2 includes a winding drum 21 and a curtain cloth 22. A groove is formed inside the first frame 11. A baffle is arranged at the opening of the groove. The baffle is snap - connected to the first frame 11. A slot is vertically formed on the baffle. The end of the curtain cloth 22 passes through the slot of the baffle and is arranged outside the first frame 11. The winding drum 21 is vertically arranged inside the groove of the first frame 11. The top end of the winding drum 21 is snap - connected to the locking assembly 3, and the bottom end of the winding drum 21 is snap - connected to the rotating seat 4. Therefore, when the winding drum 21 rotates, the winding drum 21 can drive the locking assembly 3 and the rotating seat 4 to rotate synchronously. The curtain cloth 22 is wound around the winding drum 21, and one end of the curtain cloth 22 is adhesively connected to the winding drum 21. The other end of the curtain cloth 22 is provided with a buckle, and the buckle is fixedly connected to the curtain cloth 22 by screws.
[0046] As Figure 6-8 shown, when the curtain cloth 22 is pulled out, the curtain cloth 22 will drive the winding drum 21 to rotate forward until the buckle is snap - connected to the side wall of the fourth frame 14, and then the pulling out of the curtain cloth 22 can be stopped. At this time, the winding drum 21 will also stop rotating. When it is necessary to retract the curtain cloth 22, the push rod 32 of the locking assembly 3 can be pressed, and then the locking assembly 3 can drive the winding drum 21 to rotate backward. When the winding drum 21 rotates backward, the curtain cloth 22 can be wound around the winding drum 21 again.
[0047] As Figure 9-11As shown in the figure, the locking assembly 3 includes a housing 31, a push rod 32, a disc spring 33, a ratchet tooth 34, a rotating cylinder 35, a ratchet wheel 36 and a torsion spring 37. The push rod 32 is horizontally arranged at the top of the housing 31, and the push rod 32 is slidably connected to the box body 51. The bottom end of the push rod 32 is slidably connected to the inside of the ratchet tooth 34. The disc spring 33 is horizontally arranged at the central position inside the housing 31, and one end of the disc spring 33 is clamped to the housing 31. The rotating cylinder 35 is located inside the housing 31 and is rotatably connected to the housing 31, and the rotating cylinder 35 covers the disc spring 33. The other end of the disc spring 33 is clamped to the rotating cylinder 35.
[0048] As Figure 9-11 shown, when the rotating cylinder 35 rotates forward, one end of the disc spring 33 will rotate synchronously with the rotating cylinder 35. However, since one end of the disc spring 33 is clamped to the housing 31, when the rotating cylinder 35 rotates forward, the disc spring 33 will start to tighten and store energy. Therefore, when the rotating cylinder 35 is released, the disc spring 33 will drive the rotating cylinder 35 to rotate in reverse. The ratchet wheel 36 is horizontally arranged inside the housing 31 and the ratchet wheel 36 is fixedly connected to the rotating cylinder 35 by screws. Therefore, when the rotating cylinder 35 rotates forward or backward, it can drive the ratchet wheel 36 to rotate synchronously. The winding cylinder 21 is clamped to the ratchet wheel 36.
[0049] As Figure 9-11 shown, when the winding cylinder 21 is driven by the curtain cloth 22 to rotate forward, the winding cylinder 21 will drive the ratchet wheel 36 to rotate synchronously. Similarly, when the disc spring 33 drives the ratchet wheel 36 to rotate in reverse through the rotating cylinder 35, the ratchet wheel 36 will synchronously drive the winding cylinder 21 to rotate in reverse. The ratchet tooth 34 is horizontally arranged inside the housing 31 and is not located on one side of the ratchet wheel 36, and the ratchet tooth 34 is rotatably connected to the housing 31. One end of the ratchet tooth 34 is clamped to the inside of the ratchet wheel 36, and the bottom end of the push rod 32 is slidably connected to the other end of the ratchet tooth 34.
[0050] As Figure 9-11 shown, at this time, the ratchet wheel 36 cannot rotate in the reverse direction driven by the disc spring 33. When the push rod 32 is pressed, the push rod 32 will drive the ratchet tooth 34 to rotate counterclockwise. At this time, the ratchet wheel 36 can rotate in the reverse direction driven by the disc spring 33. The torsion spring 37 is located on one side of the ratchet tooth 34 and is sleeved on the fixed shaft of the ratchet tooth 34, and both ends of the torsion spring 37 are respectively clamped to the ratchet tooth 34 and the housing 31. Therefore, when the push rod 32 is pressed to drive the ratchet tooth 34 to rotate counterclockwise, the ratchet tooth 34 will drive one end of the torsion spring 37 to rotate synchronously.
[0051] As Figure 9-11As shown, since the other end of the torsion spring 37 is clamped on the housing 31, when the ratchet 34 rotates counterclockwise, the torsion spring 37 will deform and start to store energy. When the push rod 32 is released, the torsion spring 37 will drive the ratchet 34 to rotate clockwise. At this time, one end of the ratchet 34 will snap into the inside of the ratchet wheel 36, and the other end of the ratchet 34 can push the push rod 32 upward back to its original position.
[0052] As Figure 12-14 shown, the base 5 includes a box body 51, a pressure rod 52, a fixed shell 53, a guide rod 54, a guide box 55, a clamping block 56, a spring 57, a pull rope 58 and a fixing component 6. The box body 51 is located at the bottom end of the frame 1 and is fixedly connected to the frame 1 by screws. The fixed shell 53 is vertically slidably arranged inside the box body 51. The universal wheel 7 is located below the fixed shell 53 and is fixedly connected to the bottom plate of the fixed shell 53 by screws. The guide rod 54 is vertically arranged inside the fixed shell 53 and is bonded to the center position of the bottom plate of the fixed shell 53.
[0053] As Figure 12-14 shown, the pressure rod 52 is horizontally arranged inside the fixed shell 53, and one end of the pressure rod 52 is slidably connected to the guide rod 54. The other end of the pressure rod 52 passes through the fixed shell 53 and the box body 51 and is arranged outside the box body 51. There are two groups of guide boxes 55, both of which are horizontally arranged inside the fixed shell 53. The two groups of guide boxes 55 are respectively located on both sides of the guide rod 54 and are welded to the side plates on both sides of the fixed shell 53. A clamping block 56 is slidably arranged inside each group of guide boxes 55. Grooves are vertically opened at the positions corresponding to the clamping blocks 56 on the side plates of both sides of the box body 51.
[0054] As Figure 12-14 shown, a spring 57 is also horizontally arranged inside each group of guide boxes 55, and the spring 57 is located on one side of the clamping block 56. A stretch rope is arranged on one side of each clamping block 56 where the spring 57 is located. One end of the stretch rope is bonded to the clamping block 56, and the other end of the pull rope 58 passes through the guide box 55 and is bonded to the pressure rod 52. When the pressure rod 52 is pressed downward, it will synchronously drive the two pull ropes 58 to move downward. When the stretch rope moves downward, it will pull the clamping block 56 out of the groove on the side plate of the box body 51. When the clamping block 56 is driven by the pull rope 58 to move horizontally, it will start to compress the spring 57.
[0055] As Figure 12-14As shown, at this time, lift the frame 1 upward, and the universal wheels 7 and the fixed housing 53 can move downward relative to the box body 51. At this time, the universal wheels 7 are drawn out from the inside of the box body 51. Then release the pressing rod 52, and the clamping block 56 can be pushed back into the groove on the side plate of the box body 51 by the spring 57. Therefore, when pushing the frame 1, the universal wheels 7 will not retract into the inside of the box body 51. When the frame 1 moves to the required position, the pressing rod 52 can be pressed again to take out the clamping block 56 from the groove of the box body 51. At this time, the box body 51 and the frame 1 can fall downward under the action of gravity, and the universal wheels 7 can be retracted into the inside of the box body 51.
[0056] As Figure 15-19 shown, the fixing component 6 includes a fixing rod 61, a tension spring 62 and a fixing pin 63. There are two groups of fixing rods 61, and one ends of the two groups of fixing rods 61 are rotatably connected to the box body 51. The ends of the two groups of fixing rods 61 close to the rotatable connection to the box body 51 are meshed and connected to each other. Therefore, when rotating one group of fixing rods 61, the two groups of fixing rods 61 will rotate synchronously forward or backward. The fixing pin 63 is located on one side of the fixing rod 61 and outside the box body 51, and the fixing pin 63 is slidably connected to the fixing rod 61.
[0057] As Figure 15-19 shown, therefore, when the fixing rod 61 rotates, the fixing pin 63 will rotate synchronously with the fixing rod 61. A slot corresponding to the moving path of the fixing pin 63 is opened on the box body 51. The tension spring 62 is located on one side of the fixing pin 63 and sleeved on the guide rod of the fixing pin 63, and both ends of the tension spring 62 are respectively clamped on the fixing pin 63 and the fixing rod 61. Therefore, when pulling out the fixing pin 63 from the slot of the box body 51, the fixing rod 61 can rotate forward or backward with the connection point as the center of the circle.
[0058] As Figure 15-19 shown, after the fixing rod 61 rotates, insert the fixing pin 63 into the slot of the box body 51 again to fix the relative position between the box body 51 and the fixing rod 61. Therefore, after the frame 1 is opened and the universal wheels 7 are retracted into the inside of the box body 51, the fixing pin 63 can be pulled out from the slot of the box body 51 and then the fixing rod 61 is rotated clockwise until the fixing rod 61 is in full contact with the ground and then stop rotating. Then insert the fixing pin 63 into the slot of the box body 51 again. At this time, the fixing rod 61 can support the frame 1 to prevent the frame 1 from tipping over.
[0059] Movement process of this embodiment: Press the lever 52 and then lift the frame 1 upward until the universal wheel 7 is pulled out from the inside of the box body 51, and then release the frame 1. After that, move the frame 1 to the required position through the universal wheel 7. Then, open the three groups of frames 1 according to the usage requirements. Subsequently, rotate the hook 16 counterclockwise, and then manually pull the fourth frame 14 until the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 in the three groups of frames 1 are completely opened, and then press the lever 52 again.
[0060] After the universal wheel 7 is re - received into the inside of the box body 51, pull out the fixing pin 63 from the slot of the box body 51, and then rotate the fixing rod 61 clockwise until the fixing rod 61 contacts the ground. After that, insert the fixing pin 63 into the slot of the box body 51 again. Then, manually pull the curtain 22 until the end of the curtain 22 moves to the position of the fourth frame 14, and then insert the buckle into the side wall of the fourth frame 14. After use, take out the buckle from the side wall of the fourth frame 14, and then manually press the push rod 32.
[0061] At this time, the winding drum 21 will start to wind up the rolling curtain 22 until the winding drum 21 completely winds up the curtain 22. Then, manually pull out the fixing pin 63 from the slot of the box body 51 again and rotate the fixing rod 61 counterclockwise. After the fixing rod 61 is completely retracted into the inside of the box body 51, press the lever 52 inside the box body 51 and lift the frame 1 upward until the universal wheel 7 is taken out from the inside of the box body 51. Then, start to retract the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 until the side walls of the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 are in contact with each other.
[0062] Then, rotate the hook 16 clockwise until the groove at the end of the hook 16 catches the protrusion on the side plate of the fourth frame 14. Then, the position of the screen can be moved through the universal wheel 7. After moving the screen to the placement position, retract the universal wheel 7 into the inside of the box body 51.
