Technical Field

[0001] The utility model relates to the field of gas detection, in particular to a gas leakage detection device. Background Art

[0002] Gas leak detector is a product specially used for leak detection, air tightness detection and predictive maintenance. The gas leak detector consists of a detector and an alarm control host.

[0003] The gas leak detector is mainly composed of a detection mechanism and a control mechanism. The control mechanism is a handheld-sized control host, and the control mechanism has a built-in detection element, which is connected to the gooseneck on the body. The detection head is used to approach the position where the gas needs to be detected, and then the detection head collects the gas and transports it to the detection element in the body through the gooseneck. The result is displayed on the display screen on the body. It has the advantages of easy operation, small size and high work efficiency. It is widely used in petroleum, gas, chemical, oil depot and other petrochemical industries where toxic gases exist.

[0004] After use, the existing gas leakage detection device is randomly fitted with the gooseneck tube and the body, and then placed in a tool box. As a result, when the tool box is moved, the gooseneck tube is not limited and is easy to move and bend on its own as the tool box shakes. If this continues for a long time, the gooseneck tube will cause greater wear and tear, which will easily reduce its service life.

[0005] Therefore, it is necessary to provide a new gas leakage detection device to solve the above technical problems. Utility Model Content

[0013] Preferably, a display screen is provided on the body, a plurality of control buttons are provided on the body, the display screen is aligned with the transparent plate, and a charging port is provided on one side of the body.

[0014] Compared with the related art, the gas leakage detection device provided by the utility model has the following beneficial effects:

[0015] 1. The utility model inserts the gooseneck tube into the main bracket and the auxiliary bracket. At this time, the main bracket and the auxiliary bracket cooperate to fix the gooseneck tube at multiple points. At the same time, the limiting strip of the auxiliary bracket is used to improve the stability of the gooseneck tube in the main bracket and the auxiliary bracket, thereby improving the protection of the device for the gooseneck tube.

[0016] 2. When the gooseneck tube is inserted into the main bracket, the gooseneck tube can be used to squeeze the arc plate and the rack plate and make them move. During the movement of the rack plate, the cover plate is driven to fit on the machine body by cooperating with the driving gear and the transmission gear. The cover plate can be used to protect the display screen and control buttons of the machine body. When the gooseneck tube is removed from the main bracket and the auxiliary bracket, the spring rebounds and drives the rack plate and the arc plate back to their original positions. At this time, the rack plate can automatically open the cover plate by cooperating with the driving gear and the transmission gear. At this time, the machine body can be used normally for gas detection, which effectively improves the auxiliary function of the device for the staff when in use. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] See also Figures 1 to 4 The gas leakage detection device provided by the embodiment of the utility model comprises a body 1, a display screen 11 is provided on the body 1, a plurality of control buttons 12 are provided on the body 1, the display screen 11 is aligned with the transparent plate 51, and a charging port 13 is provided on one side of the body 1;

[0025] A gooseneck tube 2 is fixedly connected to the top of the body 1 , and a detection head 21 is fixedly connected to the end of the gooseneck tube 2 .

[0026] It should be noted that the body 1 is the control host part of the gas leakage detection device. The body 1 can be operated through the control button 12. When performing gas leakage detection, the display screen 11 can display the detection results. The charging port 13 can be used to charge the lithium battery in the body 1 so that it has enough power to maintain its own operation.

[0027] It should also be noted that when detecting gas leaks, the detection head 21 is placed at the designated detection position using the gooseneck tube 2. The gas can then flow into the gooseneck tube 2 along the detection head 21 and into the body 1 through the gooseneck tube 2. The detection mechanism built into the body 1 can then detect the gas to determine whether there is a gas leakage problem.

[0028] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 and Figure 4A main bracket 3 is provided on one side of the body 1, and a limiting opening 31 is provided on the top of the main bracket 3. A rack plate 32 is slidably connected to the limiting opening 31 through a slider, and an arc plate 33 is fixedly connected to the bottom of the rack plate 32. A spring 34 is fixedly connected to the inner wall of the limiting opening 31, and the other end of the spring 34 is fixedly docked with the bottom slider of the rack plate 32. Both ends of the body 1 close to the main bracket 3 are fixedly connected with auxiliary brackets 35, and the inner top wall and the inner bottom wall of the auxiliary bracket 35 are fixedly connected with limiting strips 36.

[0029] It should be noted that: when the device is not in use, the gooseneck tube 2 is inserted into the main bracket 3 and the auxiliary bracket 35, and then the gooseneck tube 2 is limited and fixed by the limiting strip 36 of the auxiliary bracket 35. At this time, the gooseneck tube 2 can be fixed at multiple points by cooperating with the main bracket 3 and the auxiliary bracket 35. At the same time, when the gooseneck tube 2 enters the main bracket 3, the gooseneck tube 2 can squeeze the arc plate 33, thereby driving the rack plate 32 to move, and squeeze the spring 34 to make it contract.

[0030] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The body 1 is fixedly connected to a fixing frame 4 and a mounting frame 42 on one side close to the main support 3, the fixing frame 4 is rotatably connected to a driving gear 41, the mounting frame 42 is rotatably connected to a transmission gear 43, the fixing frame 4 is located between the mounting frame 42 and the main support 3, and the driving gear 41 is meshed with the transmission gear 43 and the rack plate 32 respectively;

[0031] The mounting frame 42 is rotatably connected to a cover plate 5 via a bracket, and the cover plate 5 is fixedly docked with the shaft of the transmission gear 43 via the bracket. A transparent plate 51 is fixedly connected to the cover plate 5 .

[0032] It should be noted that: after the gooseneck tube 2 is inserted into the main bracket 3, the moving rack plate 32 can drive the driving gear 41 to rotate, and the driving gear 41 can be used to drive the transmission gear 43 to rotate. At this time, during the rotation of the transmission gear 43, the shaft rod can be used to drive the cover plate 5 to be closed, so that the cover plate 5 is attached to the surface of the body 1, and the display screen 11 and the control button 12 are protected. When the device is used, the gooseneck tube 2 is removed from the main bracket 3 and the auxiliary bracket 35. At this time, the limiting pressure on the spring 34 disappears, and it rebounds, driving the rack plate 32 and the arc plate 33 to move toward the original position. At this time, the rack plate 32 can drive the transmission gear 43 to rotate in the opposite direction through the driving gear 41. At this time, the shaft rod that uses the reverse rotation of the transmission gear 43 can drive the cover plate 5 to rotate in the opposite direction, so that the cover plate 5 is automatically opened. At this time, the device can be controlled by the control button 12 on the body 1;

[0033] It should also be noted that the cover plate 5 can be used to cover the surface of the body 1, thereby protecting the display screen 11 and the control buttons 12. At the same time, when the cover plate 5 is attached to the surface of the body 1, the display screen 11 can be viewed through the transparent plate 51, which improves the convenience of use to a certain extent.

[0034] The working principle of the gas leakage detection device provided by the utility model is as follows:

[0035] First, the body 1 is charged using the charging port 13. After charging, it can be used. When detecting gas leakage, the detection head 21 is placed at a designated detection position using the gooseneck tube 2. Then, the gas can flow into the gooseneck tube 2 along the detection head 21 and into the body 1 through the gooseneck tube 2. Then, the detection mechanism built into the body 1 can detect the gas to determine whether there is a gas leakage problem.

[0036] Afterwards, the detection result can be displayed on the display screen 11, and at this time, the display screen 11 can be used to know whether there is a gas leakage problem in the detection area;

[0037] After use, the gooseneck tube 2 is inserted into the main bracket 3 and the auxiliary bracket 35, and then the limit strip 36 of the auxiliary bracket 35 is used to limit and fix the gooseneck tube 2. At this time, the main bracket 3 and the auxiliary bracket 35 cooperate to fix the gooseneck tube 2 at multiple points. At the same time, when the gooseneck tube 2 enters the main bracket 3, the gooseneck tube 2 can squeeze the arc plate 33, thereby driving the rack plate 32 to move, and squeeze the spring 34 to make it shrink. After the gooseneck tube 2 is inserted into the main bracket 3, the moving rack plate 32 can drive the driving gear 41 to rotate, and the driving gear 41 drives the transmission gear 43 to rotate. At this time, during the rotation of the transmission gear 43, the shaft rod can be used to drive the cover plate 5 to be closed, so that the cover plate 5 fits on the surface of the body 1, thereby completing the protection of the display screen 11 and the control button 12;

[0038] When the device needs to be used again, the gooseneck 2 is removed from the main bracket 3 and the auxiliary bracket 35. At this time, the limiting pressure on the spring 34 disappears and rebounds, driving the rack plate 32 and the arc plate 33 to move toward the original position. At this time, the rack plate 32 can drive the transmission gear 43 to rotate in the opposite direction through the driving gear 41. At this time, the shaft rod rotating in the opposite direction of the transmission gear 43 can drive the cover plate 5 to rotate in the opposite direction, so that the cover plate 5 is automatically opened. At this time, the device can be controlled by the control button 12 on the body 1 to continue the gas leakage detection work.
