[0030] This specific embodiment is a medical foldable screen, and its structural schematic diagram is as follows. Figures 1-9 As shown, it includes a storage shell 1 and a movable plate 2. A rotating shaft 3 is rotatably connected to the inner wall of the storage shell 1. A shielding curtain 4 is wound around the side wall of the rotating shaft 3. A through groove 5 is opened on the side wall of the storage shell 1 near the movable plate 2. The shielding curtain 4 passes through the through groove 5 and is fixedly connected to the side wall of the movable plate 2. An elastic element is provided on the side wall of the rotating shaft 3. Multiple rollers 23 are rotatably connected to the bottom surfaces of the storage shell 1 and the movable plate 2 respectively. The rollers 23 can easily pull out the movable plate 2 and reduce the friction with the ground.

[0031] The storage shell 1 has two sets of unfolding components on the side wall near the movable plate 2. The two sets of unfolding components are located at the upper and lower ends of the storage shell 1, respectively. A limit locking component is also provided between the storage shell 1 and the movable plate 2.

[0032] like Figure 7 As shown, the elastic element includes a circular shell 6 fixedly connected to the upper and lower side walls of the inner cavity of the storage shell 1, a rotating shaft 3 passing through the circular shell 6 and rotatably connected to it, and a spiral spring 7 is assembled on the side wall of the rotating shaft 3 located in the inner cavity of the circular shell 6.

[0033] The worm spring 7 is adopted to conveniently and quickly and stably wind the shielding curtain 4 when the screen is stored, so that the shielding curtain 4 can be smoothly unwound next time. Since the elastic force of the torsion spring 12 is greater than the elastic force of the worm spring 7, and the force when the first magnetic sheet 13 and the second magnetic sheet 14 are attracted, the worm spring 7 is in a tightened state after the shielding curtain 4 is unwound, but the rebounding force does not exceed the force of the torsion spring 12 and the magnetic force.

[0034] As shown in Figure 5 , the expansion assembly includes a storage groove 8 opened in the side wall of the storage shell 1, the first expansion plate 9 and the second expansion plate 10 are arranged in the storage groove 8, the first expansion plate 9 and the second expansion plate 10 are hingedly connected with each other, the side wall of the first expansion plate 9 is fixedly connected with a pin shaft 11 near the end face, the other end of the pin shaft 11 is rotatably connected with the side wall of the storage groove 8, the side wall of the pin shaft 11 is provided with a torsion spring 12, the elastic force of the torsion spring 12 is greater than the elastic force of the worm spring 7, the side wall of the movable plate 2 is provided with a groove 20, the end face of the second expansion plate 10 is L-shaped, and the end of the second expansion plate 10 is rotatably connected with the groove 20.

[0035] Specifically, the shielding curtain 4 is located between the two groups of expansion assemblies, the two groups of expansion assemblies are staggered, and the pin shafts 11 on the two groups of expansion assemblies are rotatably connected with positions away from the center of the storage shell 1, so that the first expansion plate 9 and the second expansion plate 10 are located on the upper and lower sides of the shielding curtain 4 after being expanded, thereby playing a supporting and connecting role.

[0036] As shown in Figure 8 , the side wall of the second expansion plate 10 is fixedly connected with a first magnetic sheet 13 near the side wall of the first expansion plate 9, the side wall of the groove 20 is fixedly connected with a second magnetic sheet 14, and the first magnetic sheet 13 and the second magnetic sheet 14 are matched with each other.

[0037] When the first expansion plate 9 and the second expansion plate 10 are in the expanded state, the first magnetic sheet 13 and the second magnetic sheet 14 are in the attracted state, which is used to increase the stability during placement, avoid the bending of the first expansion plate 9 and the second expansion plate 10 caused by shaking or accidental touch, and thereby cause the reset phenomenon of the movable plate 2.

[0038] As shown in Figure 3 and Figure 7 , the limiting and locking assembly includes two positioning plates 15 fixedly connected with the side wall of the movable plate 2, the side wall of the storage shell 1 is provided with a positioning groove 16 corresponding to the positioning plate 15, a plug rod 17 is movably connected with the top surface of the storage shell 1 above the positioning groove 16, the bottom end of the plug rod 17 extends into the positioning groove 16, the top end of the plug rod 17 is fixedly connected with a pull ring, the side wall of the plug rod 17 is sleeved with a tension spring 19, and the side wall of the positioning plate 15 is provided with a clamping groove 18 corresponding to the plug rod 17. The bottom end face of the plug rod 17 is inclinedly arranged.

[0039] Specific, limit locking assembly only needs to be set in the top of the storage shell 1, through the fixed upper positioning plate 15, the lower positioning plate 15 cannot be separated from the positioning groove 16, in addition, the plug rod 17 is arranged as an inclined structure, when the folding plate 2 is folded and reset, it is not necessary to pull the pull ring again, directly push the folding plate 2 to insert the positioning plate 15 into the positioning groove 16, the inclined surface of the plug rod 17 is used to make it move upward, after the positioning plate 15 is inserted in place, it is inserted into the card slot 18 through the rebound of the tension spring 19, so as to achieve the purpose of convenient use.

[0040] As shown in Figure 1 and Figure 6 The storage shell 1 and the folding plate 2 are provided with rectangular grooves 21 on the front and rear sidewalls respectively, and the support plates 22 are rotatably connected in the rectangular grooves 21.

[0041] Specifically, the support plate 22 and the rectangular groove 21 can be rotatable through shaft connection, and the shaft body can be provided with a clamping spring, a positioning pin or the like structure, so as to lock the support plate 22 after being unfolded to a horizontal state, thereby increasing the stability during supporting.

[0042] Working principle: when the screen needs to be unfolded for use, the pull ring is pulled to drive the plug rod 17 to move upward, and the tension spring 19 is stretched, so that the plug rod 17 is separated from the card slot 18, at this time, the first unfolding plate 9 and the second unfolding plate 10 are popped out outward by the action force of the torsion spring 12, the user's hand moves the folding plate 2, the rotating shaft 3 unwinds the shielding curtain 4, the volute spring 7 is tightened, the first unfolding plate 9 and the second unfolding plate 10 are unfolded from the vertical state to the V-shaped state, and then from the V-shaped state to the horizontal state, the first magnetic sheet 13 and the second magnetic sheet 14 are attracted, so as to complete the unfolding of the screen, then the two side support plates 22 are unfolded downward to play a supporting role, which is convenient for shielding the patient.

[0043] When folding and storing, only the first unfolding plate 9 and the second unfolding plate 10 are pressed inward at the hinge position, so that the first magnetic sheet 13 and the second magnetic sheet 14 are separated, the folding plate 2 is directly pushed to the storage shell 1, and the volute spring 7 stores the shielding curtain 4, when the positioning plate 15 is inserted into the positioning groove 16, the plug rod 17 is inserted into the card slot 18, and the locking is completed.

[0044] All the technical features in the embodiment can be freely combined according to actual needs.

[0045] The above embodiment is a preferred implementation scheme of the utility model, in addition to this, the utility model can be realized in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
