Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fixtures for the production of electronic flow meters of oxygen generators, and particularly relates to a fixture for the production of electronic flow meters of medical oxygen generators. Background Technique
[0002] The electronic flow meter in a medical oxygen generator is an important component for accurately measuring the flow rate of the flowing gas. It can help ensure that the output flow rate of oxygen meets medical standards and meets the needs of patients. When assembling external components of the electronic flow meter, a fixture is needed to clamp and stabilize the electronic flow meter.
[0003] The fixtures for the production of electronic flow meters of existing medical oxygen generators have the following disadvantages in the use process: Since the two ends of the electronic flow meter are respectively provided with pipes of the same diameter size, but the sizes of the electronic flow meters are different, resulting in different diameters of the pipes at both ends. Generally, when clamping and fixing the pipes at both ends of the electronic flow meter, the fixture can only clamp and fix the electronic flow meter with pipes of a fixed diameter size, and cannot clamp and fix the pipes with different diameter sizes, resulting in limited application range. At the same time, the distance between the two clamping structures for clamping the pipes cannot be adjusted according to the size of the electronic flow meter. Secondly, when manually assembling external components of the electronic flow meter, the pitching angle of the electronic flow meter also needs to be adjusted. When adjusting, the electronic flow meter needs to be loosened from the fixture first, and then the angle is adjusted and clamped and fixed again through the fixture, resulting in great inconvenience when adjusting the angle. Therefore, a fixture for the production of electronic flow meters of medical oxygen generators is needed. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a fixture for the production of electronic flow meters of medical oxygen generators to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0015] In the present utility model, when using the fixture for the production of the electronic flowmeter of the medical oxygen generator, the two-way screw can be rotated first through the handwheel. Since the two-way screw is threadedly connected to the two sliders, the two L-shaped guide rods can move towards each other or away from each other, so that the two spline shafts can move towards each other or away from each other, and then the distance between the two lower clamping seats can be adjusted, so as to facilitate the clamping and fixing of the pipelines at both ends of the electronic flowmeter with different sizes.

[0024] Embodiment
[0025] Since pipes with the same diameter are provided at both ends of the electronic flowmeter, but the sizes of the electronic flowmeters are different, resulting in different diameters of the pipes at both ends. Generally, when clamping and fixing the pipes at both ends of the electronic flowmeter, the clamp can only clamp and fix the electronic flowmeter with pipes of a fixed diameter size, and cannot clamp and fix pipes with different diameters, resulting in a limited scope of application. At the same time, the distance between the two clamping structures for clamping the pipes cannot be adjusted according to the size of the electronic flowmeter. Secondly, when manually assembling external components to the electronic flowmeter, the elevation and depression angles of the electronic flowmeter need to be adjusted. When adjusting, the electronic flowmeter needs to be loosened from the clamp first, and then the angle is adjusted and then clamped and fixed again through the clamp, resulting in great inconvenience when adjusting the angle;
[0026] Therefore, please refer to Figures 1-3 , the present utility model provides a clamp for the production of an electronic flowmeter of a medical oxygen generator, including: a support table 1, two symmetrically arranged support seats 2 are fixedly connected to the top of the support table 1, two symmetrically arranged lower clamping seats 4 are provided between the two support seats 2, V-shaped clamping mouths are provided at the tops of the lower clamping seats 4, guide columns 41 are fixedly connected to the rear edge of the top of each lower clamping seat 4, upper clamping seats 42 are movably sleeved on the outside of the guide columns 41, inverted V-shaped clamping mouths are provided at the bottoms of the upper clamping seats 42, hand-tightening screws 43 are rotatably connected to the positions of the upper clamping seats 42 far from the guide columns 41, and the bottoms of the hand-tightening screws 43 are threadedly connected to the threaded channels 44 provided on the lower clamping seats 4;
[0027] It further includes a distance adjustment structure 3 and a pitch angle adjustment structure 5. The distance adjustment structure 3 is installed on the support table 1 and is connected to the two support seats 2 and the two lower clamping seats 4;
[0028] The pitch angle adjustment structure 5 is installed on two supporting seats 2 and is connected between the support platform 1 and the distance adjustment structure 3.
[0029] After the hand-tightening screw 43 is completely loosened from the threaded channel 44, the upper clamping seat 42 can be manually rotated 180 degrees outside the guide post 41, so that the electronic flowmeter can be quickly placed on the two lower clamping seats 4.
[0030] Furthermore, as Figures 1-3 shown, specifically, the distance adjustment structure 3 includes spline sleeves 36 rotatably connected to the two supporting seats 2. In the mounting shaft holes of the two spline sleeves 36, spline shafts 35 adapted to each other are movably installed. One end of the two spline shafts 35 facing each other is fixedly connected to the outside of the lower clamping seat 4, and one end of the two spline shafts 35 away from each other is rotatably connected to the L-shaped guide rods 31. The L-shaped guide rods 31 are movably inserted into the supporting seats 2. One end of the two L-shaped guide rods 31 facing each other is fixedly connected with a slider 32 having a convex cross-section. The two sliders 32 are both slidably connected to the chute provided at the top of the support platform 1. The two sliders 32 are symmetrically arranged and are threadedly connected to the same bidirectional screw 33. Both ends of the bidirectional screw 33 are rotatably connected to the corresponding chute. One end of the bidirectional screw 33 extends to the outside of the support platform 1 and is fixedly connected with a handwheel 34.
[0031] The supporting seat 2 is provided with an activity through opening convenient for the cooperation with the L-shaped guide rod 31.
[0032] Furthermore, as Figures 1-3 shown, specifically, the pitch angle adjustment structure 5 includes gears d56 fixedly connected to the outside of the two spline sleeves 36. Below the gears d56, gears c55 are meshed and connected. In the mounting shaft holes of the two gears c55, the same transmission shaft 51 is fixedly connected. Both ends of the transmission shaft 51 are rotatably connected to the supporting seats 2. In the middle of the outside of the transmission shaft 51, a gear b53 is fixedly connected. Below the gear b53, a gear a52 is meshed and connected. The gear a52 is a crown gear, and the gear a52 is fixedly connected to the outside of the output shaft of the motor 54. The motor 54 is fixedly connected to the support platform 1.
[0033] The crown gear and the gear b53 are vertically arranged, which is a transmission structure of the prior art, and the corresponding technology can be found on Baidu.
[0034] In summary, when using the fixture for producing the electronic flowmeter of the medical oxygen generator, the two-way screw 33 can be rotated first through the handwheel 34. Since the two-way screw 33 is threadedly connected to the two sliders 32, the two L-shaped guide rods 31 can move towards each other or away from each other, so that the two spline shafts 35 can move towards each other or away from each other, and then the distance between the two lower clamping seats 4 can be adjusted, which is convenient for clamping and fixing the pipelines at both ends of the electronic flowmeter with different sizes. When clamping and fixing, the two hand-tightening screws 43 can be tightened respectively, so that the upper clamping seats 42 move downward outside the guide posts 41, so as to clamp and fix the pipelines at both ends of the electronic flowmeter. In addition, when it is necessary to adjust the pitching angle of the clamped and fixed electronic flowmeter, the motor 54 can be started, so that the gear b53 drives the gear a52, so that the transmission shaft 51 drives the two gears c55 to rotate. The gears c55 will drive the gears d56 respectively, so that the spline sleeve 36 rotates, and the clamped and fixed sub-flowmeter is adjusted in pitching angle to meet the different angles required during the production and assembly of the electronic flowmeter of the oxygen generator.
