It should be understood that the specific embodiments described here are only used to explain the utility model, and do not limit the utility model.

[0017] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0018] See also Figure 1 The embodiment of the utility model provides a gas filling detection device for a combustible gas detector, and the gas filling detection device for a combustible gas detector includes:

[0019] A gas cylinder 1 and a partition plate 2, one end of the partition plate 2 is fixedly connected to the gas cylinder 1, and the other end of the partition plate 2 is fixedly provided with a baffle 3; an introduction mechanism 4, which is fixedly installed on the gas cylinder 1, and the air inlet end and the air outlet end of the introduction mechanism 4 are respectively arranged outside the gas cylinder 1 and inside the gas cylinder 1, and are used to introduce combustible gas or non-combustible gas into the gas cylinder; an outlet mechanism 5, which is installed on the gas cylinder 1, the air inlet end of the outlet mechanism 5 is fixedly connected to the baffle 3, and the air outlet end is arranged outside the gas cylinder 1, and is used to introduce combustible gas or non-combustible gas into the detector for detecting the detector; a push rod 6, which is slidably installed on the gas cylinder 1, one end of the push rod 6 is arranged outside the gas cylinder 1 and fixedly connected with a push handle 7, and the other end is arranged inside the gas cylinder 1 and fixedly connected with a piston 8, and the piston 8 is used to push the combustible gas or non-combustible gas from the outlet mechanism 5 into the detector.

[0020] When using the gas filling detection device of the combustible gas detector, first, when the piston 8 is at the rightmost end, the gas source can be connected to the inlet mechanism 4. Under the action of the gas source pressure, the inlet mechanism 4 opens, and the combustible gas is added into the gas storage cylinder 1 by the inlet mechanism 4. With the introduction of the combustible gas, the piston 8 gradually moves to the leftmost end. After the piston 8 moves to the leftmost end, the gas source is disconnected, the inlet mechanism 4 is naturally closed, and the control end of the outlet mechanism 5 is pulled to open the outlet mechanism 5. The outlet mechanism 5 is aligned with the detector, and the push handle 7 is pushed. The push handle 7 drives the piston 8 to move to the right through the push rod 6, thereby pushing the combustible gas from the outlet mechanism 5 into the detector, and observing whether the detector detects the combustible gas.

[0021] like Figure 2 As shown, as a preferred embodiment of the utility model, the introduction mechanism 4 includes: a connecting pipe 41, which is provided with a thread on the outside, and the connecting pipe 41 can be connected to the gas source through the thread, and the connecting pipe 41 is fixedly connected to an introduction pipe 42 connected to the gas cylinder 1, and the combustible gas or non-combustible gas can be introduced into the gas cylinder 1 through the introduction pipe 42; a one-way plate 43, which is fixedly arranged on the inner wall of the connecting pipe 41, and the one-way plate 43 is provided with a one-way port; a one-way conduction component 44, which is fixedly arranged on the one-way plate 43 and is arranged in conjunction with the one-way port to control the opening and closing of the one-way port.

[0022] When introducing the combustible gas into the gas storage cylinder 1, the gas source is connected to the connecting pipe 41 through the thread. After the connection is completed, the gas source pushes the one-way conductive component 44 to move downward under the push of the gas pressure of the gas source, and the one-way conductive component 44 can open the one-way port opened by the one-way plate 43, and the combustible gas can flow into the gas storage cylinder 1 through the one-way port and the introduction pipe 42. After the combustible gas is added, the gas source is removed, and under the elastic force of the one-way conductive component 44, the one-way conductive component 44 can close the one-way port to prevent the combustible gas from overflowing.

[0023] like Figure 1 As shown, as a preferred embodiment of the utility model, the one-way conduction component 44 includes: a sleeve 441, which is fixedly mounted on the one-way plate 43 and distributed on both sides of the one-way port, a slide plate 442 is slidably arranged in the sleeve 441, and a return spring 443 is fixedly connected between the slide plate 442 and the inner wall of the sleeve 441; a pull rod 444, one end of which is fixedly connected to the slide plate 442, and the other end is arranged outside the sleeve 441 and fixedly connected to a pull plate 445, a one-way ball 446 is fixedly arranged on the pull plate 445, and the one-way ball 446 and the one-way port are arranged in cooperation with each other to control the opening and closing of the one-way port.

[0024] When the combustible gas is introduced into the gas cylinder 1, the combustible gas can push the one-way ball 446, the pull plate 445, the pull rod 444, and the slide plate 442 to move downward along the sleeve 441 and compress the return spring 443, and the combustible gas can flow into the gas cylinder 1. After the gas filling is completed, the gas source is disconnected. Under the elastic force of the return spring 443 itself, the one-way ball 446 can move upward to close the one-way port to prevent the combustible gas from flowing back.

[0025] like Figure 1 and Figure 3 As shown, as a preferred embodiment of the utility model, the outlet mechanism 5 includes: a gas collecting hopper 51, which is fixedly connected to the baffle 3, and the two ends of the gas collecting hopper 51 are respectively arranged inside and outside the baffle 3, and the end of the gas collecting hopper 51 arranged outside the baffle 3 is fixedly connected to a lead-out pipe 52, and the end of the lead-out pipe 52 arranged outside the gas storage cylinder 1 is fixedly connected to an insertion pipe 53, and the insertion pipe 53 can be connected to the detector; a baffle 54, which is fixedly arranged in the lead-out pipe 52 and has a lead-out port, and the combustible gas or the non-combustible gas can be led out from the lead-out port; a clamping rod 55, which is slidably arranged in the gas storage cylinder 1. A bayonet is provided on the cylinder 1, and the bayonet provided by the clamping rod 55 is cooperated with a clamping assembly 56 installed on the air storage cylinder 1.

[0026] When the combustible gas is introduced into the detector, the pull handle 57 is pulled up, and the pull handle 57 drives the clamping rod 55, the connecting rod 58 and the sealing plate 59 to move upward and compress the compression spring 510, so that the sealing plate 59 can open the outlet opened by the baffle 54, and the clamping rod 55 moves upward to make the bayonet gradually approach the clamping assembly 56. When the bayonet and the clamping assembly 56 are flush, the clamping assembly 56 can enter the bayonet under the push of its own elastic force, thereby ensuring the opening device of the outlet. At this time, the push handle 7 can be pushed, and the combustible gas can flow into the detector through the gas collecting bucket 51, the outlet pipe 52 and the insertion pipe 53; when the outlet pipe 52 is closed, the control end of the clamping assembly 56 is pulled, and after the clamping assembly 56 is separated from the bayonet, the sealing plate 59 can slide along the baffle 54 and gradually close the outlet under the push of the elastic force of the compression spring 510, and the outlet pipe 52 is in a closed state.

[0027] like Figure 4As shown, as a preferred embodiment of the utility model, the clamping assembly 56 includes: a fixing plate 561, which is fixedly installed on the gas cylinder 1 and the black box is on one side of the clamping rod 55, a sleeve 562 is fixedly provided on the fixing plate 561, a sleeve rod 563 is sleeved on the sleeve 562, and the sleeve rod 563 is fixedly connected with a limiting rod 564 which is arranged in cooperation with the bayonet; a push spring 565, whose two ends are respectively fixedly connected with the limiting rod 564 and the sleeve 562, and is used to push the limiting rod 564 into the bayonet to limit the movement of the clamping rod 55; a pull handle 566, which is fixedly connected with the limiting rod 564, and is used to pull the limiting rod 564 out of the bayonet.

[0028] When controlling the limiting rod 564 to disengage from the bayonet, pull the handle 566, which can drive the limiting rod 564 and the sleeve rod 563 to move to the left along the sleeve 562 and compress the push spring 565. The limiting rod 564 can move to the left to disengage from the bayonet, and the compression spring 510 can push the sealing plate 59 to close the outlet.
