Description

Technical Field

[0001] The invention relates to the technical field of respiratory trainers, in particular to a stable support type respiratory trainer. Background Art

[0002] A breathing trainer is a type of medical device, mainly used for breathing-related training of patients. Breathing training is beneficial to improving the trainee's chest contraction and expansion ability, and greatly improves the trainee's vital capacity and lung strength. The essence of breathing training is mainly to train the chest diaphragm muscles. When using existing breathing trainers, it is easy for the patient to pull the trachea, causing the trainer to shake or even fall over. Therefore, we have launched a stable support type breathing trainer.

[0003] The existing patent (Announcement No.: CN109675260B) discloses a breathing trainer that can exercise the thoracic diaphragm muscle. The technical solution adopted by the invention is: a breathing trainer, including a base, one side of the upper surface of the base is provided with a U-shaped tube with an opening facing upward, and the other side is provided with a vertical mounting frame; a sliding piston is respectively provided inside the tube body on both sides of the U-shaped tube, and a plurality of weighted balls are provided in the tube body between the sliding pistons, and the diameter of the weighted balls matches the diameter of the tube hole of the U-shaped tube; the interior of the U-shaped tube near both ends is also provided with a standard limiter. The invention can facilitate breathing training and exercise the thoracic diaphragm muscle, and has a simple structure.

[0004] The existing patent (Announcement No.: CN213965037U) discloses a child breathing trainer of pediatric medical equipment, including a box body, the front end face of the box body is provided with a protruding port, the front end face of the box body is located on the left side of the protruding port and is fixedly connected to a fixed block, the front end face of the box body is located on the right side of the protruding port and is fixedly connected to a C-shaped fixed block, an L-shaped slide plate is slidably connected between the C-shaped fixed block and the front end face of the box body, the lower end face of the box body is fixedly connected to the support column, and the lower end face of the support column is fixedly connected to a floor plate. The utility model relates to the technical field of medical equipment. The child breathing trainer of pediatric medical equipment solves the problems that children have no interest in breathing trainers, the training results cannot be clearly seen, and the trainer has a short life.

[0005] In the prior art, the respiratory trainer is placed on the ground by relying on a base. However, since the supporting part of the respiratory trainer is relatively long, when the respiratory trainer is in use, the user often pulls the trachea excessively, which can easily cause the top of the respiratory trainer to be pulled, causing one side of the base to tilt and shake, and in severe cases even cause the respiratory trainer to topple over. In order to prevent this from happening, some respiratory trainers increase the stability of the respiratory trainer by widening the base. This causes the respiratory trainer to occupy too much area, making it inconvenient to place in departments with limited space. Summary of the invention

[0022] In the present invention, when the expansion component is expanding, the suction cup will store energy until it expands to the maximum state, and the energy storage spring rebounds to pop the suction cup downward, so that the suction cup is adsorbed on the ground.

[0023] In the present invention, in the process of the energy storage spring ejecting the suction cup downward, the arc pressure rod first contacts the ground, and the piston plate is pulled by the end of the arc pressure rod that is not in contact with the arc pressure rod in the initial state to draw a vacuum inside the suction cup, so that the suction cup is more firmly adsorbed to the ground and the stability is improved. At the same time, the arc pressure rod will also drive the crescent plate to press down and fix the extended skirt of the edge of the suction cup, so as to prevent the suction cup from curling and losing the adsorption force when the breathing trainer is impacted and displaced.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 technical personnel in this field without creative work are within the scope of protection of the present invention.

[0037] In this embodiment, Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the expansion component 2 includes a knob 201 rotatably connected to the middle of the base component 1 through a connecting shaft, an active rod 202 is fixedly connected to the middle of the bottom surface of the knob 201 through a connecting shaft, an end of the active rod 202 away from the knob 201 is rotatably connected to a driven rod 203 through a connecting shaft, and an end of the driven rod 203 not connected to the active rod 202 is rotatably connected to a movable shaft 204, and the movable shaft 204 is divided into an inner shaft 204a, a middle shaft 204b and an outer shaft 204c, and the movable shaft 204 runs through the broken line rod 20 5, the broken line rod 205 is composed of an upper rod 205a and a lower rod 205b, and the upper rod 205a and the lower rod 205b are connected in sequence to form a ring structure, the base assembly 1 includes a central disk 101, the outer ring of the central disk 101 is integrally formed with four sets of fixed guide rails 102, the insides of the four sets of fixed guide rails 102 are all slidably connected with telescopic arms 103, and four triangular blocks 104 are fixedly connected between the four sets of fixed guide rails 102; the four triangular blocks 104 are respectively connected to the multi-stage telescopic rod 3018 The limit rod 3017 is connected, a slider 105 is slidably arranged on the inner side of the telescopic arm 103, a buffer spring 106 is fixedly connected between the slider 105 and the inner wall end of the telescopic arm 103, and a column 107 is fixedly connected to the end of the telescopic arm 103 away from the center disk 101, and a universal wheel 108 is arranged at the bottom end of the column 107; when the breathing trainer is working, after placing it at a specified position, the rotating knob 201 drives the active rod 202 to rotate, and the rotation of the active rod 202 can drive the driven rod 203 to rotate, When the driven rod 203 rotates, it will drive all the upper rods 205a and the lower rods 205b to shrink or expand synchronously through the inner shaft 204a connected to it. Since the top of the outer shaft 204c is connected to the slider 105, when the extension component 2 moves, the slider 105 can drive the telescopic arm 103 in the base component 1 to expand and contract, thereby achieving the purpose of adjusting the coverage range of the base of the breathing trainer, thereby enhancing stability. When it is not needed, the base area can be reduced through the extension component 2 for easy placement.

[0038] In this embodiment, Figure 2 , Figure 6 and Figure 7As shown, the suction cup assembly 3 includes an articulated seat 301 fixedly connected to the bottom surface of the inner shaft 204a and the bottom surface of the outer shaft 204c, the middle part of the articulated seat 301 is hinged with an inclined connecting rod 302, the bottom end of the inclined connecting rod 302 is hinged with a lower pressure plate 303, the bottom surface of the lower pressure plate 303 is fixedly connected with two energy storage springs 304, one side of the lower pressure plate 303 is integrally formed with a lever 305, the bottom ends of the two energy storage springs 304 are fixedly connected with an installation frame 306, and the middle part of the installation frame 306 is fixedly connected There is a piston cylinder 307, and the bottom end of the piston cylinder 307 is connected to the suction cup body 301; during the expansion process of the extension component 2, the inner shaft 204a and the outer shaft 204c will approach each other, thereby driving the corresponding hinged seat 301 to approach each other, and the approach of the hinged seat 301 will push the lower pressure plate 303 downward through the inclined connecting rod 302, and the lower pressure plate 303 will push the installation frame 306 and the lever 305 to move downward synchronously through the energy storage spring 304, and the installation frame 306 drives the suction cup body 3011 below to descend.

[0039] In this embodiment, Figure 7 and Figure 8As shown, the piston cylinder 307 is internally slidably connected with a piston plate 308, the top surface of the piston plate 308 is respectively fixedly connected with a piston rod 309 and a return spring 3010, the top of the piston rod 309 is fixedly connected with two pull ropes 3012, the ends of the two pull ropes 3012 away from the piston cylinder 307 are connected to one end of the arc pressure rod 3013, the end of the arc pressure rod 3013 connected to the pull rope 3012 is integrally formed with a crescent piece 3014, the bottom edge of the suction cup body 3011 is provided with an extended skirt, and the crescent piece 3014 is located at the extension skirt. 3014 is located just above the edge of the mounting frame 306, the arc-shaped pressure rod 3013 passes through the bottom surface of the mounting frame 306, and a circular connecting piece 3015 is integrally formed in the middle of the arc-shaped pressure rod 3013, and an arc-shaped spring 3016 is fixedly connected between the circular connecting piece 3015 and the bottom surface of the mounting frame 306, and the height of the end of the arc-shaped pressure rod 3013 away from the crescent piece 3014 is lower than the bottom surface height of the suction cup body 3011; when the mounting frame 306 descends, the arc-shaped pressure rod 3013 is synchronously driven to descend, because the end of the arc-shaped pressure rod 3013 away from the crescent piece 3014 is lower than the bottom surface height of the suction cup body 3011 The bottom surface of the suction cup body 3011, before the suction cup body 3011 is about to touch the ground, the arc pressure rod 3013 will slide at the bottom of the installation frame 306, and the arc pressure rod 3013 will squeeze the arc spring 3016. After the suction cup body 3011 contacts the ground, the two ends of the arc pressure rod 3013 are at the same height. At this time, the crescent piece 3014 at the end of the arc pressure rod 3013 squeezes the extended skirt of the edge of the suction cup body 3011 between the ground and the crescent piece 3014. This structure can prevent the breathing trainer from being used when the breathing trainer is in use. When the training device is displaced by external impact, the extended skirt part of the suction cup body 3011 will not curl up, causing a gap between the internal and external space of the suction cup body 3011 and losing the adsorption effect. During the movement of the arc pressure rod 3013, the end connected to the pull rope 3012 will move down, and the pull rope 3012 will pull the piston rod 309 upward. The piston rod 309 pulls the piston plate 308 upward inside the piston cylinder 307, and the interior of the suction cup body 3011 is pumped into a negative pressure state, so that the suction cup body 3011 is firmly adsorbed on the ground.

[0040] In this embodiment, Figure 2 and Figure 6As shown, the number of the central axis 204b is several, wherein the top surface and the bottom surface of the central axis 204b closest to the diagonal line of the base assembly 1 are respectively fixedly connected to the limit rod 3017 and the installation rod 3019, the outer surface of the limit rod 3017 is fixedly connected to the multi-stage telescopic rod 3018, and the bottom end of the installation rod 3019 is fixedly connected to the elastic telescopic rod 3020, and the elastic telescopic rod 3020 is located below the bottom surface of the installation frame 306; when the installation frame 306 is pushed downward by the lower pressing plate 303, the bottom surface of the installation frame 306 will first contact with the elastic telescopic rod 3020, and the elastic telescopic rod 3020 ... The telescopic rod 3020 contacts and is blocked by the elastic telescopic rod 3020. At this time, as the expansion component 2 continues to expand, the lower pressure plate 303 will continue to move downward. Since the mounting frame 306 is blocked by the elastic telescopic rod 3020, the lower pressure plate 303 will compress the energy storage spring 304 to store energy. In addition, during the expansion process of the expansion component 2, the middle axis 204b connected to the mounting rod 3019 at the bottom surface moves away from each other, thereby driving the elastic telescopic rod 3020 at the bottom of the mounting frame 306 to gradually move away from the mounting frame 306. When the extension component 2 is expanded to the maximum, the elastic telescopic rod 3020 is separated from the bottom surface of the installation frame 306, and the energy storage spring 304 rebounds to release the installation frame 306 downward, and the installation frame 306 drives the suction cup body 3011 to contact the ground. This structure can prevent the suction cup body 3011 from contacting the ground too early during the expansion of the expansion component 2, causing the suction cup body 3011 to be damaged or shortened in service life due to friction along the ground translation, and also reduces the adsorption effect of the suction cup body 3011, because the suction cup body 3011 is translated along the ground during translation. It is inevitable that some tiny impurities will enter the gap between the suction cup body 3011 and the ground, causing the suction cup body 3011 to not fit tightly against the ground and the sealing effect to deteriorate. It should be noted that the two side walls of the installation frame 306 are inclined outward from bottom to top. After the elastic telescopic rod 3020 is separated from the bottom surface of the installation frame 306, the elastic telescopic rod 3020 will contact the surface of the two side walls of the installation frame 306. The inclined side walls are beneficial to the range of the elastic telescopic rod 3020 and guide the elastic telescopic rod 3020 to the bottom of the bottom surface of the installation frame 306.

[0041] In this embodiment, Fig. 9 and Fig.10As shown, the cleaning component 4 includes a fixed frame 401 fixedly connected to the end of the upper rod 205a and the end of the lower rod 205b, respectively. The fixed frame 401 is divided into an inner frame 401a and an outer frame 401b. The inner and outer frames 401a and 401b are both slidably connected to the limiting blocks 402. The bottom surfaces of the two limiting blocks 402 are respectively integrally formed with an inner lifting rod 403 and an outer lifting rod 404. The bottom end of the outer lifting rod 404 is fixedly connected with a cleaning brush plate 405. The middle parts of the inner and outer lifting rods 403 and 404 are penetrated by the lever 305. During the expansion process of the expansion component 2, the upper rod 205a and the lower rod 205b connected by the outer shaft 204c will rotate in opposite directions with the outer shaft 204c as the axis. At this time, the upper rod 205a and The lower rod 205b drives the outer frame 401b and the inner frame 401a to rotate in opposite directions around the outer axis 204c respectively. The outer frame 401b drives the cleaning brush plate 405 to rotate through the outer lifting rod 404. At the same time, the cleaning brush plate 405 also moves outward with the expansion component 2 to achieve the purpose of cleaning the ground while rotating, paving the way for the subsequent suction cup body 3011 to better fit the ground. The lever 305 will descend with the lower pressure plate 303, driving the outer lifting rod 404 and the inner lifting rod 403 to descend. Since the inner lifting rod 404 and the outer lifting rod 403 are not provided with an energy storage mechanism, during the expansion process of the expansion component 2, the two sets of lifting rods drive the cleaning brush plates 405 and the wiping strips 409 at their respective bottom ends to contact the ground and wipe the ground.

[0042] In this embodiment, Fig. 9 and Fig.10 As shown, the bottom end of the inner lifting rod 403 is fixedly connected to a water storage bin 406, and the interior of the water storage bin 406 is slidably connected to a piston push plate 407, and the bottom surface of the piston push plate 407 is connected to a wiping strip 409 through a vertical connecting rod 408. Two rebound springs 4010 are arranged between the top surface of the wiping strip 409 and the bottom surface of the water storage bin 406. The cross section of the water storage bin 406 is an inverted "L" shape, and the bottom surface of the extended part of the water storage bin 406 is connected to a plurality of squeeze drippers 4011; under the push of the inner lifting rod 403, the water storage bin 406 descends, and the descent of the water storage bin 406 will be affected by the rebound spring 4010. 10 drives the wiping strip 409 to descend and make the wiping strip 409 fit the ground. After the wiping strip 409 contacts the ground, the rebound spring 4010 is compressed. At this time, the wiping strip 409 pushes the piston push plate 407 to move up in the water storage tank 406 through the vertical connecting rod 408, and the liquid in the water storage tank 406 is squeezed out from the squeezing dripper 4011. The squeezed liquid will drip on the ground and then wiped by the wiping strip 409 to wipe the ground clean. At the same time, the ground after being wiped by the liquid has better sealing when it fits with the suction cup body 3011, so that the breathing trainer can be more stably fixed in the desired position.

[0043] The use method and advantages of the present invention: When the stable support type breathing trainer is used, the working process is as follows:

[0044] First, move the breathing trainer to the desired position, and then adjust the size of the base coverage through the expansion component 2 to improve the stability of the trainer. In the process of expansion of the expansion component 2, it will also drive the cleaning component 4 to clean the ground so that the suction cup body 3011 can be better adsorbed on the ground. After the expansion component 2 is expanded to the maximum extent, the suction cup body 3011 contacts the ground and automatically pumps the inside of the suction cup body 3011 to a negative pressure state, so that the suction cup body 3011 is firmly adsorbed on the ground, making the breathing trainer more stably placed. At the same time, in the process of pumping the suction cup body 3011 to a vacuum state, it will also drive the crescent piece 3014 to press the extended skirt of the suction cup body 3011 down on the ground to prevent the suction cup body 3011 from curling up and losing its adsorption ability when the breathing trainer is displaced by external collision.
