[0002] There are many kinds of standard gases, which are usually manually configured according to GB / T 5274.1-2018 "Preparation of mixed gases for gas analysis calibration Part 1: Preparation of primary mixed gases by weighing method". Usually, multiple gases are weighed and mixed in a certain proportion. This filling process is called "gas distribution". The gas distribution process requires connecting the mother gas cylinder and the gas nozzle of the gas cylinder to be filled through the gas line and quick connector.

[0003] Since the size specifications of gas cylinders are usually not fixed, gas cylinders have various volumes such as 8L and 4L, and the heights of the gas nozzles of gas cylinders are also slightly different, the connection and separation processes of quick connectors are currently mostly performed manually, which is time-consuming and labor-intensive, thereby reducing the gas filling efficiency and increasing the workload of staff.

[0011] A quick-connect mechanism located on one side of the fixture for connecting the gas tank;

[0012] The second explosion-proof motor is located at one end of the X-direction linear module and is used to provide X-direction moving power.

[0013] Preferably, the bottom of the explosion-proof motor 1 is fixedly connected to the top of the Z-direction linear module, the X-direction linear module is arranged outside the Z-direction linear module, the top of the X-direction linear module is fixedly connected with a joint clamp, one end of the joint clamp is provided with a setting fixture, the side of the setting fixture away from the joint clamp is detachably connected with a quick connection mechanism, and the side of the X-direction linear module away from the setting fixture is fixedly connected with the explosion-proof motor 2.

[0015] Preferably, the quick connection mechanism also includes a gas cylinder connecting seat, the outside of which is fixedly connected to a gas nozzle, a snap-fitting ring groove is provided in the middle of the gas nozzle, and the plurality of snap-fitting balls are all snap-fitted with the snap-fitting ring groove.

[0016] Preferably, the sealing ring is slidably connected to the inside of the internal thread connector, and a sealing groove is provided on a side of the sliding sleeve away from the tension spring.

[0017] Preferably, the internal thread of the internal thread connector away from the clamping ball is connected to a threaded clamping block, and the outside of the threaded clamping block is fixedly connected to a hexagonal sleeve.

[0018] Preferably, a rubber pad is fixedly connected to a side of the sealing ring away from the fixing ring, and the retaining spring is arranged inside the internal threaded connector.

At the same time, the quick connection mechanism can be moved forward and backward. When the quick connection mechanism is moved to align with the connecting tube of the gas cylinder, the explosion-proof motor 2 is controlled to start and drive the joint clamp to extend forward and clamp on the sliding sleeve. Then the joint clamp is controlled to push forward. At this time, the card ball lacks pressure, so it can move in the space between the internal thread connector and the sliding sleeve. When the internal thread connector moves When the outside of the cannula is connected again, the locking ring groove is located on the inner side of the locking ball. At this time, the sliding sleeve is loosened and can be pulled to move backward under the action of the tensioning spring, so that the sliding sleeve can be reset. Therefore, the inner side of the sliding sleeve can continue to be pressed against the outside of the locking ball, so that the locking ball can be locked in the inside of the locking ring groove and cannot move. Therefore, the connection between the internal threaded connector and the connecting cannula can be achieved. After the inflation is completed, the sliding sleeve is pushed forward again, the locking ball can move, and the internal threaded connector is pulled backward, so that the internal threaded connector can be pulled out of the outside of the connecting cannula, thereby realizing automatic and quick connection and disassembly.

[0024] 1.
