This field involves a variety of industries, including manufacturing, automation, industrial engineering, etc.

[0003] Gas leak detectors are important tools for line patrol and leak detection. Line patrollers need to bend down hundreds or even thousands of times every day. When testing in inconvenient places such as under balconies and near obstacles, they need to squat for a long time, which not only affects work efficiency but also increases the labor intensity of line patrollers. Some existing handheld gas leak detectors have short probes. If the probe length is increased, the detection response time will be extended, and the power of the suction pump will also need to be improved. In addition, the number of detection points on flat roads will increase, and manual detection cannot guarantee stability and efficiency. In addition, long-term use will increase the load.

[0004] In order to reduce the workload of line inspectors without changing the main structure of the leak detector, the development of adding an extension rod and rollers at the tail of the leak detector has solved this problem very well. Utility Model Content

[0012] The outer wall of the connecting threaded rod is threadably connected to the inner wall of the plastic pipe clamp.

[0013] As a further description of the above technical solution:

[0014] The rubber roller is connected to the front end outer wall of the bracket frame through a screw rod and a screw nut.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the screw rod contacts the inner wall of the bolt connection hole.

[0017] As a further description of the above technical solution:

[0018] The outer walls of the handle and the telescopic rod fixing fixture are both provided with friction pads.

[0019] The utility model has the following beneficial effects:

The extension mechanism 1 has a diameter of 20mm, a length of 450mm, and an extension length of 1.6 meters. The extension mechanism 1 includes a handle 101. The operator can hold the handle 101 to use the device for detection. The front end outer wall of the handle 101 is fixedly connected to an aluminum alloy tube 102. The aluminum alloy tube 102 is a telescopic rod with a telescopic range of 0.6 -1.5 meters, the outer wall of the aluminum alloy tube 102 is fixedly connected with a telescopic rod fixing fixture 103, which can be used to fix the aluminum alloy tube 102 when it is extended or retracted. The outer walls of the handle 101 and the telescopic rod fixing fixture 103 are provided with friction pads, which can increase the friction between the operator's hand and the device, making it easier for the operator to pick up and test. The front end outer wall of the aluminum alloy tube 102 is fixedly connected with a plastic pipe clamp 104, which can be used to fix the mounting mechanism 2 to the front end of the extension mechanism 1.

[0030] Reference Figure 3The front end inner wall of the plastic pipe clamp 104 is threadedly connected to the mounting mechanism 2, and the gas leak detector 4 can be placed in the mounting mechanism 2 for detection. The mounting mechanism 2 includes a connecting threaded rod 201, and the outer wall of the connecting threaded rod 201 is threadedly connected to the inner wall of the plastic pipe clamp 104, so that the mounting mechanism 2 and the extension mechanism 1 can be conveniently and quickly disassembled and installed, which is convenient for carrying. The front end outer wall of the connecting threaded rod 201 is fixedly connected to the bracket frame 202, and the bracket frame 202 can be used to fix the gas leak detector 4. It is welded with a lightweight galvanized sheet material. The front end outer wall of the bracket frame 202 is provided with a bolt connection hole 203, and the mobile mechanism 3 can be fixed to the front end outer wall of the bracket frame 202 through the bolt connection hole 203.

[0031] Reference Figure 4 The inner wall of the mounting mechanism 2 is detachably mounted with a gas leak detector 4, which is a prior art known to professionals in the field. The front end outer wall of the mounting mechanism 2 is threadedly connected to a moving mechanism 3, which is mounted on the mounting mechanism 2 through the moving mechanism 3. The operator can easily push the device to move on the ground.
