[0030] The utility model provides a laboratory gas detection device, which aims to solve the problems proposed in the prior art that the connection between the delivery hose and the docking sleeve does not have an anti-bending structure, the delivery hose is easily bent during use, affecting the accuracy of gas detection inside the laboratory, and the delivery hose is inconvenient to store when not in use.

[0031] like Figure 1-7 As shown, a laboratory gas detection device provided by an embodiment of the present invention includes a base plate 1, a hose 4 and a detector body 8. An anti-bending mechanism 2 is provided on the left side of the top of the base plate 1. A storage box 5 is fixedly connected to the left side of the base plate 1. A box cover 6 is provided on the top of the storage box 5.

[0032] The anti-bending mechanism 2 includes an arc-shaped horn cover 201, a rubber ring 202 and a fixed column 203. The bottom of the fixed column 203 is fixedly connected to the top of the base plate 1, the top of the fixed column 203 is fixedly connected to the bottom of the arc-shaped horn cover 201, the right side of the rubber ring 202 is fixedly connected to the left side of the arc-shaped horn cover 201, and the left side of the hose 4 passes through the arc-shaped horn cover 201 and extends to the outside of the arc-shaped horn cover 201.

[0033] In the technical solution of the present invention, the hose 4 is first passed through the arc-shaped horn cover 201 from right to left, and then the detector body 8 is moved to the top of the base plate 1, so that the surface of the detector body 8 contacts the inner wall of the block 7, and the front side of the body contacts the rear side of the limit block 10, and then the limit button 15 is rotated so that the rear side of the limit button 15 is in close contact with the front side of the detector body 8. At this time, the friction between the surface of the detector body 8 and the inner wall of the block 7 increases, and the detector body 8 can be limited to the top of the base plate 1. At this time, the arc-shaped inner wall of the arc-shaped horn cover 201 can support the hose 4 when the hose 4 is bent to prevent the hose 4 from bending, and the rubber ring 202 can prevent the edge of the arc-shaped horn cover 201 from scratching the hose 4. After the use of the hose 4 is completed, it needs to be retracted. When storing, the handle 14 is held to move the winding drum 12 and the limiting disk 13 out of the storage box 5, and the hose 4 can be wound on the surface of the winding drum 12. At this time, the limiting disk 13 can limit the hose 4 to prevent the hose 4 from being separated from the winding drum 12. Then the winding drum 12 with the hose 4 wound around it is moved into the storage box 5. At this time, the hose 4 can be stored. Then the box cover 6 is inserted between the two rails 3, so that the hose 4 is moved to the inside of the notch 18, and the storage box 5 can be covered, avoiding the problem that the connection between the delivery hose and the docking sleeve proposed in the prior art solution does not have an anti-bending structure, and the delivery hose is prone to bending when in use, affecting the accuracy of gas detection inside the laboratory, and is inconvenient to store when the delivery hose is not needed.

[0034] Please refer to Figure 4A reel 12 is movably mounted within the storage box 5. The front and rear sides of the reel 12 are fixedly connected to limit plates 13. In this embodiment, the hose 4 can be reeled by wrapping it around the reel 12. The limit plates 13 then position the hose 4, preventing it from detaching from the reel 12. This effectively reels the hose 4.

[0035] For further information, please refer to Figure 2 and Figure 4 The front and rear sides of the winding drum 12 are fixedly connected to pillars 16. Handles 14 are provided on both sides of the top of the winding drum 12. The bottom of the handles 14 is fixedly connected to the top of the pillars 16, and the bottom of the pillars 16 is fixedly connected to the bottom of the inner wall of the storage box 5. In this embodiment, the winding drum 12 and the limit plate 13 can be moved out of the storage box 5 by holding the handles 14. After the winding drum 12 is moved into the storage box 5, the pillars 16 will support the winding drum 12, achieving the effect of facilitating the movement and support of the winding drum 12.

[0036] Please continue to refer to Figure 1 and Figure 5 The top of the front and rear sides of the storage box 5 are fixedly connected to the rails 3, and the box cover 6 is movably inserted between the two opposite sides of the rails 3. In this embodiment, by inserting the box cover 6 between the two rails 3, the hose 4 is moved into the inside of the gap 18, and the storage box 5 can be covered, achieving the effect of conveniently covering the storage box 5.

[0037] Please refer to Figure 1 and Figure 5 A pull ring 17 is fixedly connected to the top of the box cover 6, and a notch 18 is formed on the top of the box cover 6. In this embodiment, the box cover 6 can be easily pulled by holding the pull ring 17, and the box cover 6 can be easily moved to overlap with the storage box 5 by moving the hose 4 into the notch 18, thereby covering the storage box 5, thereby achieving the effect of conveniently covering the storage box 5.

[0038] Also, please refer to Figure 1 and Figure 2 The rear side of the top of the bottom plate 1 is fixedly connected to a clamping block 7, and both sides of the front side of the bottom plate 1 are fixedly connected to limit blocks 10. The surface of the detector body 8 contacts the inner wall of the clamping block 7, and the rear side of the limit block 10 contacts the front side of the detector body 8. In this embodiment, by moving the detector body 8 to the top of the bottom plate 1, so that the surface of the detector body 8 contacts the inner wall of the clamping block 7 and the front side of the body contacts the rear side of the limit block 10, the detector body 8 can be positioned on the top of the bottom plate 1, thereby achieving the effect of positioning the detector body 8.

[0039] Please refer to Figure 1and Figure 7 A limit button 15 is provided on the front side of the limit block 10. The rear side of the limit button 15 passes through the limit block 10 and is in close contact with the front side of the detector body 8. The surface of the limit button 15 is connected to the internal thread of the limit block 10. In this embodiment, by rotating the limit button 15, the limit button 15 is connected to the internal thread of the limit block 10. When the limit button 15 is rotated, the limit button 15 can be moved. When the limit button 15 is moved until the rear side of the limit button 15 is in close contact with the front side of the detector body 8, the friction between the surface of the detector body 8 and the inner wall of the clamping block 7 increases, and the detector body 8 can be limited to the top of the bottom plate 1, thereby achieving the effect of limiting the detector body 8 to the top of the bottom plate 1.

[0040] Also, please refer to Figure 1 The front and rear sides of the right bottom of the bottom plate 1 are fixedly connected to legs 9, and the bottom of the legs 9 and the front and rear sides of the left bottom of the storage box 5 are fixedly connected to anti-slip pads 11.
