Description

Technical Field

[0001] This invention relates to the field of pediatric oxygen meter technology, specifically a safety fixing device for pediatric oxygen meters that combines buffer protection and anti-fall-off functions. Background Technology

[0002] Oxygen flow meters are typically connected to oxygen supply devices for emergency oxygen administration and oxygen inhalation for hypoxic patients to ensure the normal functioning of the patient's respiratory system.

[0003] The safety fixing device for pediatric oxygen meters can only be used with a few standard-sized oxygen meters. For neonatal-specific miniature meters, irregularly shaped pressure reducers, and pediatric oxygen meters from different brands, it may either clamp too loosely, causing shaking, or squeeze too tightly, damaging the meter casing and valve. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pediatric oxygen meter safety fixing device with both buffer protection and anti-fall-off functions, comprising a bracket and a wall. An external gear frame is rotatably connected to the inner wall of the bracket. Multiple fixing bolts are threaded onto the inner wall of the wall. Multiple gears are meshed with the tooth ends of the external gear frame. Multiple threaded rods are rotatably connected to the inner wall of the bracket. A movable frame is threaded onto the outer wall of each threaded rod. Two rubber pads are installed on the outer wall of the movable frame. An oxygen meter is slidably connected to the outer walls of the multiple rubber pads. A connecting rod and a rotating rod are rotatably connected to the inner wall of the bracket. A worm gear is fixedly connected to one end of the connecting rod, a worm is fixedly connected to one end of the rotating rod, and a rotating block is fixedly connected to the other end of the rotating rod. A fixing component is provided on the inner wall of the bracket, and a buffer component is provided on the outer wall of the bracket.

[0006] By adopting the above technical solution: the bracket is fixed to the wall by four fixing bolts threaded to the wall. Then, the worm gear meshes with the worm wheel, and the external gear frame meshes with multiple gears, forming a transmission structure together with the rotating rod, the connecting rod, and the four threaded rods. Rotating the rotating block indirectly drives the four threaded rods to rotate together through the transmission structure. The four threaded rods together drive the four moving frames to move inward, so that the multiple rubber pads are tightly attached to the outer wall of the oxygen meter. The oxygen meter is fixed by the fixing components and the buffer components, achieving the effect of installing oxygen meters of different brands.

[0007] Preferably, the fixing assembly includes an external gear frame two, which is rotatably connected to the inner wall of the bracket. Multiple gears two are meshed at the tooth ends of the external gear frame two. Multiple rotating rods two are rotatably connected to the inner wall of the bracket. A connecting rod two and a rotating rod three are rotatably connected to the inner wall of the bracket. A worm gear two is fixedly connected to one end of the connecting rod two. A worm gear two is fixedly connected to one end of the rotating rod three. A rotating block two is fixedly connected to the other end of the rotating rod three. A bevel gear one, a bevel gear two, and a threaded rod two are rotatably connected to the inner wall of the movable frame one. A movable frame two is threadedly connected to the outer wall of the threaded rod two. Multiple movable frames two are slidably connected to the outer wall of the oxygen meter, and movable frames two are slidably connected to the inner wall of the movable frame one.

[0008] Preferably, the buffer assembly includes a movable frame three, which is slidably connected to the outer wall of the support. The outer wall of the movable frame three is provided with multiple springs, and a rubber pad two is fixedly connected to the outer wall of the movable frame three.

[0009] Preferably, multiple springs are disposed on the outer wall of the bracket, and the rubber pad is slidably connected to the outer wall of the oxygen meter.

[0010] Preferably, the worm gear two is meshed with the tooth end of the worm wheel two, and one of the gears two is fixedly connected to the other end of the connecting rod two.

[0011] Preferably, the second gear is fixedly connected to one end of the second rotating rod, and the first bevel gear is slidably connected to the outer wall of the second rotating rod.

[0012] Preferably, the second bevel gear is fixedly connected to one end of the second threaded rod, and the first bevel gear is meshed with the tooth end of the second bevel gear.

[0013] Preferably, the worm gear is meshed with the tooth end of the worm wheel, and one of the gears is fixedly connected to the other end of the connecting rod.

[0015] Preferably, the plurality of fixing bolts penetrate the inner wall of the bracket and are threadedly connected to the inner wall of the wall.

[0016] This invention provides a safety fixing device for pediatric oxygen gauges that combines cushioning protection and anti-fall-off functions. It has the following beneficial effects: 1. This invention uses a worm gear and worm wheel meshing with an external gear frame to drive multiple gears, which together with a rotating rod, connecting rod, and threaded rod form a transmission structure. The rotating block drives four threaded rods to rotate synchronously through this structure, causing the moving frame to move inward and allowing multiple rubber pads to fit tightly against the outer wall of the oxygen meter, thus achieving the effect of installing oxygen meters of different brands.

[0017] 2. In this invention, the rotating block 2 drives the connecting rod 2, which in turn drives the four rotating rods 2 to rotate via the gear 2 and the external gear frame 2. The rotating rods 2 drive the bevel gear 2 and the threaded rod 2, causing the movable frame 2 to move on the outer wall of the movable frame 1 and come into contact with the oxygen gauge, thereby preventing the oxygen gauge from falling off.

[0018] 3. The present invention uses four springs set between the movable frame three and the support, so that the movable frame three, through the elastic force of the springs, causes the rubber pad two to move the oxygen meter to fit tightly against the four movable frames two, so that the springs and rubber pad two can provide a buffering effect for the oxygen meter.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a pediatric oxygen meter safety fixing device with both cushioning protection and anti-fall-off functions, including a bracket 1 and a wall 3. An external gear frame 4 is rotatably connected to the inner wall of the bracket 1. Multiple fixing bolts 2 are threadedly connected to the inner wall of the wall 3. Multiple gears 6 are meshed with the tooth ends of the external gear frame 4. Multiple threaded rods 5 are rotatably connected to the inner wall of the bracket 1. A movable frame 7 is threadedly connected to the outer wall of the threaded rods 5. Two rubber pads 8 are installed on the outer wall of the movable frame 7. An oxygen meter 14 is slidably connected to the outer wall of the multiple rubber pads 8. A connecting rod 9 and a rotating rod 11 are rotatably connected to the inner wall of the bracket 1. One end of the connecting rod 9 is fixedly connected to the worm gear 10, one end of the rotating rod 11 is fixedly connected to the worm 12, and the other end of the rotating rod 11 is fixedly connected to the rotating block 13. The inner wall of the bracket 1 is provided with a fixing component 15, and the outer wall of the bracket 1 is provided with a buffer component 16. The worm 12 is meshed with the tooth end of the worm gear 10. One gear 6 is fixedly connected to the other end of the connecting rod 9 and to one end of the threaded rod 5. Multiple movable frames 7 are slidably connected to the outer wall of the bracket 1, and multiple fixing bolts 2 penetrate the inner wall of the bracket 1 and are threadedly connected to the inner wall of the wall 3.

[0023] Specifically, by rotating the rotating block 13, it drives the worm gear 12 to rotate via the rotating rod 11. This causes the worm wheel 10 to drive the connecting rod 9 to rotate via the worm gear 12. The connecting rod 9, through multiple gears 6 and the external gear frame 4, drives the four threaded rods 5 to rotate. The threaded rods 5 are threadedly connected to the inner wall of the moving frame 7. The four threaded rods 5 together drive the four moving frames 7 to move towards the center of the bracket 1. This allows the rubber pads 8 on the threaded rods 5 to be tightly pressed against the outer wall of the oxygen meter 14. The rubber pads 8 prevent the oxygen meter 14 from rotating. Through the fixing component 15 and the buffer component 16, the oxygen meter 14 is completely fixed, thus achieving the effect of installing oxygen meters 14 of different brands.

[0024] Please see the appendix Figure 1 - Appendix Figure 8The fixing component 15 includes an external gear frame 1501, which is rotatably connected to the inner wall of the bracket 1. Multiple gears 1503 are meshed with the tooth ends of the external gear frame 1501. Multiple rotating rods 1502 are rotatably connected to the inner wall of the bracket 1. A connecting rod 1508 and a rotating rod 1510 are rotatably connected to the inner wall of the bracket 1. A worm gear 1509 is fixedly connected to one end of the connecting rod 1508, a worm 1511 is fixedly connected to one end of the rotating rod 1510, and a rotating block 1512 is fixedly connected to the other end of the rotating rod 1510. A bevel gear 1504, a bevel gear 1505, and a threaded rod 1 are rotatably connected to the inner wall of the moving frame 7. 506, the outer wall of the threaded rod 1506 is threaded with a movable frame 1507, multiple movable frames 1507 are slidably connected to the outer wall of the oxygen gauge 14, the movable frame 1507 is slidably connected to the inner wall of the movable frame 7, the worm gear 1511 is meshed with the tooth end of the worm wheel 1509, one gear 1503 is fixedly connected to the other end of the connecting rod 1508, the gear 1503 is fixedly connected to one end of the rotating rod 1502, the bevel gear 1504 is slidably connected to the outer wall of the rotating rod 1502, the bevel gear 1505 is fixedly connected to one end of the threaded rod 1506, and the bevel gear 1504 is meshed with the tooth end of the bevel gear 1505.

[0025] Specifically, by rotating the rotating block 1512, the rotating block 1512 drives the connecting rod 1508 to rotate via the rotating rod 1510, the worm gear 1511, and the worm wheel 1509. The connecting rod 1508 then drives the four rotating rods 1502 to rotate via the gear 1503 and the external gear frame 1501. The rotating rods 1502 then drive the bevel gear 1505 and the threaded rod 1506 to rotate via the bevel gear 1504 sliding on the outer wall. This causes the moving frame 1507 to move on the outer wall of the moving frame 7, so that the four moving frames 1507 come into contact with the oxygen gauge 14, thereby preventing the oxygen gauge 14 from falling off.

[0026] Please see the appendix Figure 3 and attached Figure 6 The buffer assembly 16 includes a movable frame 1601, which is slidably connected to the outer wall of the support 1. The outer wall of the movable frame 1601 is provided with multiple springs 1602. A rubber pad 1603 is fixedly connected to the outer wall of the movable frame 1601. The multiple springs 1602 are provided on the outer wall of the support 1, and the rubber pad 1603 is slidably connected to the outer wall of the oxygen gauge 14.

[0027] Specifically, the movable frame 1601 is connected to the support 1 by four springs 1602, so that the movable frame 1601, under the elastic force of the springs 1602, drives the rubber pad 1603 to continuously press against the outer surface of the oxygen gauge 14, so that the oxygen gauge 14 is always in a stable compressed state; the oxygen gauge 14 can effectively absorb and mitigate external impacts or vibrations by means of the elastic deformation ability of the springs 1602 and the material buffering characteristics of the rubber pad 1603.

[0028] Working principle: The bracket 1 is firmly installed on the wall 3 using four fixing bolts 2. Then, through the meshing between the worm gear 12 and the worm wheel 10, and the meshing between the external gear frame 4 and multiple gears 6, the rotating block 13 is rotated, indirectly driving the four threaded rods 5 to rotate synchronously, causing the four movable frames 7 to move inward. Multiple rubber pads 18 are made to adhere to the outer wall of the oxygen meter 14. Rotating the rotating block 1512 causes it to drive the connecting rod 1508 to rotate through the transmission of the rotating rod 1510, the worm gear 1511, and the worm wheel 1509. The connecting rod 1508 then drives the four rotating rods 1502 to rotate through the meshing of the gear 1503 and the external gear frame 1501. The bevel gear 1504 on the rotating rod 1502 drives the bevel gear 1505 and the threaded rod 1506 to rotate, so that the four moving frames 1507 come into contact with the oxygen meter 14 and cause the oxygen meter 14 to press tightly against the rubber pad 1603 on the moving frame 1601. The oxygen meter 14, through the elasticity of the spring 1602 and the buffering properties of the rubber pad 1603 itself, can effectively absorb and mitigate external impacts or vibrations, thus adapting to oxygen meters 14 of different sizes and shapes and improving the versatility and stability of the device.
