Description

Technical Field

[0001] The embodiment of the invention relates to the field of electromechanical control technology, and in particular to a rotary soft curtain sealing device. Background Art

[0002] For cylindrical soft seals, airbag sealing is generally used, such as a sphygmomanometer. This sealing method has a small lateral sealing range and cannot meet the needs of scenarios with a large lateral sealing range. For example, people's waist circumferences vary greatly. If the same sealing device can meet the needs of most people's waists, a ring-shaped airbag will obviously not solve this problem.

[0003] The electric-controlled soft curtain sealing device is a key component used in the negative pressure sealed cabin for the lower limbs of the human body. The sealed cabin is a cylindrical structure, one end of which is closed by a head, and the other end is closed by a soft curtain sealing device around the waist of the human body, thereby achieving the sealing of the cabin. The shape and circumference of the human waist are different, and how to achieve the sealing between the human body and the hatch of the sealed cabin is the key to the specific problem to be solved.

DETAILED DESCRIPTION

[0025] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a rotary soft curtain sealing device, comprising a frame 1 for fixing and supporting, and a sealed cabin 2 fixed to one end of the frame 1, a mounting flange 3 is provided at the entrance of the sealed cabin 2, an annular rotating wheel 4 is installed on the mounting flange 3, the annular rotating wheel 4 comprises a fixed wheel 5 and a rotating wheel 6, the fixed wheel 5 is embedded in the rotating wheel 6, and the fixed wheel 5 is fixedly connected to the mounting flange 3, a soft curtain door 7 is installed between the fixed wheel 5 and the rotating wheel 6, a soft curtain pressing sheet 8 is provided on the outer edge of the soft curtain door 7, one side of the soft curtain door 7 is respectively installed on the fixed wheel 5 through the soft curtain pressing sheet 8, and the other side of the soft curtain door 7 is installed on the rotating wheel 6 through the soft curtain pressing sheet 8;

[0027] A gear ring 9 is provided on the inner ring of the rotating wheel 6, and an outer ring column spur gear 10 meshing with the gear ring 9 is provided at the bottom of the rotating wheel 6, and the outer ring column spur gear 10 is driven to rotate by a motor 11 installed at the bottom of the rotating wheel 6. A flexible pressure sensor is provided in the middle of the soft curtain door 7. The front and rear ends of the soft curtain door 7 are folded to form a wrinkled edge 15 in the middle, and the flexible pressure sensor is arranged along the direction in which the wrinkled edge 15 extends.

[0028] When the present invention is working, the patient's upper body lies on the frame 1 and the lower body enters the sealed cabin 2. After lying down, the switch button set in the sealed cabin 2 is started to turn on the power supply to make the motor 11 work. At this time, the soft curtain door 7 is in an open state, and the motor 11 drives the ring gear 9 to rotate, driving the rotating wheel 6 to rotate to realize the forward and reverse rotation of the annular rotating wheel 4. The motor 11 drives the rotating wheel 6 to rotate forward. Since the fixed wheel 5 is fixedly connected to the mounting flange 3, the rotating wheel 6 and the fixed wheel 5 rotate relatively, tightening the soft curtain door 7 so that the soft curtain door 7 is combined with the patient's waist, thereby achieving sealing. When the flexible pressure sensor embedded in the soft curtain door 7 reaches the set pressure value, the motor 11 stops rotating and the entire cabin door is closed; after the treatment is completed, the exit button set on the sealed cabin is started, and the motor 11 rotates in the opposite direction, which drives the soft curtain door 7 to loosen and the cabin door is opened.

[0029] A plurality of steel balls 12 are arranged at equal intervals on the circumferential surface of the fixed wheel 5, and the specific number of the steel balls 12 is 480. A plurality of grooves 14 matching with the plurality of steel balls 12 are provided on the flange 13 of the rotating wheel 6, and each steel ball 12 is embedded in each groove 14. The fixed wheel 5 and the rotating wheel 6 achieve relative rotation through the cooperation of the steel balls 12 and the grooves 14. The relative rotation of the fixed wheel 5 can prevent the soft curtain door 7 from being completely folded when the motor 11 drives the rotating wheel 6 to rotate, causing excessive pulling of the soft curtain door 7.

[0030] The gear ring 9 in the rotating wheel 6 is geared according to a module of 1, and meshes with an outer ring spur gear 10 which is also geared according to a module of 1. The precise gear meshing can well adjust the lateral opening area of ​​the soft curtain door 7.

[0031] There are two soft curtain pressing sheets 8, and the front and rear ends of the soft curtain door 7 are folded into a cylindrical shape, and the two soft curtain pressing sheets 8 are respectively fixedly connected to the fixed wheel 5 and the rotating wheel 6. Since the soft curtain door 7 is locked in its axial position by rotational folding, it adopts a double-sided glued special sealing cloth, so it can fit tightly with the patient's waist when folded.

[0032] A fixing ring bracket 16 is provided between the sealed cabin 2 and the mounting flange 3. The fixing ring bracket 16 provides support for the patient when lying in the sealed cabin 2. The fixing ring bracket 16 can be movably mounted on the sealed cabin 2 so that the position of the fixing ring bracket 16 can be adjusted.

[0033] The diameter of the mounting flange 3 is greater than the diameter of the rotating wheel 6 , and a plurality of adjusting screw knobs 17 are provided on the mounting flange 3 , and the ends of the adjusting screw knobs 17 are screw-engaged with the fixing ring bracket 16 .

[0034] Elastic rings 18 are arranged inside the front and rear ends of the soft curtain door 7, which can automatically adapt to the size of the opening when the soft curtain door 7 is opened. When the human body passes through the frame 1 and enters the sealed cabin 2, the elastic rings 18 on the soft curtain door 7 will clamp the part of the human body in the soft curtain door 7, thereby improving the sealing of the waist part of the human body.

[0035] The present invention drives the folded cylindrical soft curtain door 7 through the motor 11 to increase the lateral sealing area of ​​the sealed cabin 2, which can meet the lower limb treatment needs of patients with different waist circumferences. At the same time, the cylindrical soft curtain door 7 can provide greater wrapping and protection for the patient's waist in the axial direction of the soft curtain door 7 through the rotation of the rotating wheel 6, so as to increase the sealing effect.

[0036] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
