On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] like Figures 1 to 6 As shown, an embodiment of the utility model provides a user replacement ventilation detection device, comprising a box body 1 and a box cover 101 arranged at the opening of the box body 1, and further comprising:

[0040] The limiting plates 204 are located in the box body 1 and are symmetrically arranged with two of them;

[0041] An adjusting portion connected to the limiting plates 204 to adjust the distance between the two limiting plates 204;

[0050] ② When the gas concentration reaches 90%, the control module collects the gas concentration value every 5 minutes. When the gas concentration value collected for three consecutive times is greater than 90%, a shut-off valve closing instruction is sent. At this time, the shut-off valve is closed and the replacement is completed, and the replacement qualification information is sent to the user's handheld terminal.

[0051] Step 3: Complete the user ventilation replacement project. The user closes the user replacement gas detection head and remotely controls the detection device to vent the mixed gas in the device;

[0052] The detection device can solve the user safety problem. By using this device, the safety risk caused by the user approaching the discharge port to detect the change of gas concentration is avoided; at the same time, the problem of gas concentration accuracy is solved.

[0053] More preferably, the user first adjusts the limit plate 204 to a suitable position on the inner side of the box body 1 through the adjustment part according to the size of the user's replacement ventilation detection device, so that the detection device is placed between the two limit plates 204. At this time, the limit plate 204 is adjusted again to fit the surface of the detection device to clamp and fix it, and then the limit part drives the limit fastener to fasten and fix it to a suitable position through the rotating part of the limit part, so that the distance between the two limit plates 204 is fixed, so that the detection device can be stably placed in the box body 1.

[0054] like Figures 1 to 6 As shown, sponge strips 205 are respectively provided on both sides of the limiting plate 204;

[0055] Specifically, the sponge pad 104 is disposed in the box body 1, and the support plate 203 is penetrated in the sponge pad 104;

[0056] More preferably, the sponge strip 205 is fitted with the detection device through the limiting plate 204, so that the sponge strip 205 and the bottom of the detection device are fitted with the sponge pad 104 at the same time, and the sponge pad 104 and the sponge strip 205 have soft and rough materials, and cooperate with each other to stably place the detection device in the box body 1.

[0057] like Figures 1 to 6 As shown, the adjustment unit includes:

[0058] The moving member is a moving rod 202, which has two parts and is disposed in the box body 1 and is located directly below the limiting plate 204, so that the limiting plate 204 can move laterally in the box body 1; and is located at the bottom of the sponge pad 104;

[0059] The supporting member is a support plate 203 , one end of which is fixed to the top of the moving rod 202 , and the other end of which is fixedly connected to the limiting plate 204 .

[0060] In the embodiment of the utility model, in order to adjust the placement space in the box body 1 to adapt to the detection device, the user adjusts the distance between the two moving rods 202 so that the two moving rods 202 drive the limit plate 204 to move in opposite directions along the guide section through the support plate 203. When the detection device is placed at a suitable position on the top of the sponge pad 104, the two moving rods 202 drive the limit plate 204 to move closer to each other along the guide section through the support plate 203. At this time, the two relatively installed sponge strips 205 fit the surface of the detection device for clamping, so that the sponge strip 205 and the sponge pad 104 use their own soft and rough materials to cooperate with each other to place the detection device firmly in the box body 1, and one side of the limit plate 204 is in an arc shape, so that the sponge strip 205 can fit the detection device with an arc surface, and cooperate with the inner walls on both sides of the box body 1 to clamp and fix the detection device with an arc surface. At this time, the limit plate 204 can clamp and fix detection devices of different shapes, thereby improving the versatility of the limit plate 204.

[0061] like Figures 1 to 6 As shown, the rotating member comprises:

[0062] A rotating rod 201 is rotatably connected to one end of the moving member;

[0063] The connecting member is a rotating plate 3, which is arranged on the rotating rod 201, so that the rotating rod 201 can rotate longitudinally with the moving member as the axis, and the limiting fastener and the positioning member can be fastened or released;

[0064] The limiting fastener comprises:

[0065] A spring 302, one end of which is fixed to the fixing member, and the other end of which is fixedly connected to the buckle member;

[0066] The buckle member is a fixed ball 303, which is buckled in the positioning member;

[0067] The fixing member is a fixing ring 301, which is fixed on the connecting member and elastically connected to the buckling member to support the buckling and fixing or releasing of the buckling member and the positioning member.

[0068] In the embodiment of the present invention, when the user needs to adjust the distance between the two limit plates 204, the user can first rotate the rotating rod 201 to drive the rotating plate 3 to rotate together with the moving rod 202 as the center in the direction away from the buckle ring 102, so that the rotating plate 3 drives the fixing ring 301 to rotate, and at the same time, the fixing ball 303 uses its own arc surface to fit with the arc surface of the buckle ring 102 under the support of the fixing ring 301 to squeeze the spring 302 to contract, so that the fixing ball 303 is taken out from the inner side of the buckle ring 102, and the fixing effect of the buckle ring 102 and the fixing ball 303 is released, and then the limit plate 204 is adjusted. When the user has adjusted the distance between the two limit plates 204, In order to keep the limiting plate 204 at a suitable distance, the user drives the rotating plate 3 to rotate together with the moving rod 202 in the direction close to the buckle 102 by rotating the rotating rod 201, so that the rotating plate 3 drives the fixing ring 301 to rotate, and at the same time, the fixing ball 303 uses its own arc surface to fit with the arc surface of the buckle 102 under the support of the fixing ring 301 to squeeze the spring 302 to contract, so that when the fixing ball 303 is located at the ring mouth of the buckle 102, the rebound force of the spring 302 is used to make the fixing ball 303 and the buckle 102 buckle and fix, thereby limiting the limiting plate 204 at a suitable position through the fixing effect of the fixing ball 303 and the buckle 102.

[0069] like Figures 1 to 6 As shown, the positioning member includes:

[0070] There are multiple buckles 102 arranged on the box cover 101, so that the fastening member is fastened and fixed with two of the buckles 102 that are closest to each other.

[0071] Specifically, a sealing gasket 103 is installed on the inner side of the top wall of the box cover 101, and is tightly fitted to the top edge of the box body 1. The box body 1 is provided with pleated leaves 2, and the moving part is inserted into the pleated leaves 2 and fixedly connected to the moving part.

[0072] In the embodiment of the utility model, the user opens the top opening of the box body 1 by rotating the box cover 101 with the hinge as the center under the support of the box body 1. At this time, when the user adjusts the distance between the two limit plates 204 by moving the rod 202, when the two moving rods 202 move away from each other, the pleated leaves 2 on both sides of the moving rod 202 are squeezed, so that the pleated leaves 2 between the two moving rods 202 are stretched. When the two moving rods 202 approach each other, the pleated leaves 2 between the two moving rods 202 are squeezed to stretch the pleated leaves 2 on both sides of the moving rod 202, so that when the moving rod 202 moves along the guide section, the pleated leaves 2 can always close the opening of the guide section, and the fixing effect of the fixing ball 303 and the fastener is used to make the box cover 101 drive the sealing gasket 103 to fit tightly with the edge of the box body 1. At this time, the sealing gasket 103 and the pleated leaves 2 cooperate with each other to make the detection device placed on the inner side of the box body 1 not easily affected by moisture, thereby achieving a waterproof and moisture-proof effect.

[0073] In the embodiment of the utility model, the user needs to first rotate the box cover 101 to open the top opening of the box body 1, and then drive the rotating plate 3 to rotate in the direction away from the buckle ring 102 by rotating the rotating rod 201, so that the rotating plate 3 drives the fixing ring 301 to rotate, and at the same time, the fixing ball 303 uses its own arc surface to fit with the arc surface of the buckle ring 102 under the support of the fixing ring 301 to squeeze the spring 302 to contract, so that the fixing ball 303 is taken out from the inner side of the buckle ring 102, and the fixing effect of the buckle ring 102 and the fixing ball 303 is released. At this time, by adjusting the two moving rods 2 02, the two moving rods 202 drive the limit plates 204 to move in opposite directions along the guide section through the support plates 203. When the two moving rods 202 move away from each other, the pleated leaves 2 on both sides of the moving rods 202 are squeezed, so that the pleated leaves 2 between the two moving rods 202 are stretched out. At this time, the moving rods 202 drive the limit plates 204 to move away from each other along the guide section through the support plates 203. At this time, the two relatively installed sponge strips 205 also move away from each other, so that the detection device is placed at a suitable position on the top of the sponge pad 104.

[0074] Then, the two moving rods 202 are driven by the support plate 203 to move the limiting plate 204 closer to each other along the guide section. At this time, the two relatively installed sponge strips 205 are clamped against the surface of the detection device, so that the sponge strips 205 and the sponge pad 104 use their own soft and rough materials to cooperate with each other to firmly place the detection device in the box body 1. When the two moving rods 202 are close to each other, the pleated leaves 2 between the two moving rods 202 are squeezed, thereby stretching the pleated leaves 2 on both sides of the moving rod 202, so that when the moving rod 202 moves along the guide section, the pleated leaves 2 can always close the opening of the guide section. When the user adjusts the distance between the two limiting plates 204 to be suitable for the detection When the size of the device is adjusted, in order to enable the limit plate 204 to maintain a suitable distance to clamp and fix the detection device, the user rotates the rotating rod 201 to drive the rotating plate 3 to rotate with the moving rod 202 as the center in the direction close to the buckle ring 102, so that the rotating plate 3 drives the fixing ring 301 to rotate, and at the same time, the fixing ball 303 uses its own arc surface to fit with the arc surface of the buckle ring 102 under the support of the fixing ring 301 to squeeze the spring 302 to contract, so that when the fixing ball 303 is located at the ring mouth of the buckle ring 102, the rebound force of the spring 302 is used to make the fixing ball 303 and the buckle ring 102 buckle and fix, so that the limit plate 204 is limited to a suitable position by the fixing action of the fixing ball 303 and the buckle ring 102;

[0075] Finally, the fixing ball 303 and the fastener are used to fix the box cover 101 and the sealing gasket 103 to fit tightly with the edge of the box body 1. At this time, the sealing gasket 103 and the pleated leaf 2 cooperate with each other to prevent the detection device placed on the inner side of the box body 1 from being easily affected by moisture, thereby achieving a waterproof and moisture-proof effect.

[0076] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
