[0039] Example 2

[0040] Based on Embodiment 1, a preferred embodiment of the portable leak detection sensor mounting base for natural gas pipeline networks provided by this utility model is, for example... Figures 1 to 5 As shown: The adjustment component 1 includes: a groove 104 formed at equal angles on the surface of the mounting base 5; a threaded rod 106 rotatably connected to the inner wall of the fixed groove 3, one end of the threaded rod 106 extending into the interior of the groove 104 and fixedly connected to a handle 101; and a threaded block 105 threadedly connected to the surface of the threaded rod 106, the top end of the threaded block 105 being fixedly connected to the bottom end of the sliding base 6.

[0041] In this embodiment, the screwdriver or other tools are used to rotate the handle 101, which drives the threaded rod 106 to rotate.

[0046] The working principle of this utility model is as follows: First, the mounting base 5 is installed and fixed in a suitable position using external bolts. Then, the rotating handle 101 is rotated using a screwdriver or other tools to drive the threaded rod 106 to rotate. The threaded engagement between the threaded rod 106 and the threaded block 105 causes the threaded block 105 to slide, thereby driving the sliding seat 6 to slide. The sliding distance of the three sliding seats 6 can be adjusted according to the diameter of the circle on the sensor body 4, so that it can meet the installation and fixing of sensor bodies 4 of different sizes, improving its applicability. Furthermore, the O-ring rubber ring 103 is used to increase the friction between the surface of the rotating handle 101 and the inner wall of the groove 104, so that a larger force is required to rotate, thus achieving the limiting and fixing of the rotating handle 101 after rotation.

[0047] Then, the upper mounting feet of the sensor body 4 are aligned with the sliding seats 6. The pull rod 201 is then used to pull the rotating block 208 upward, causing the sliding block 205 to slide and compress the mounting spring 202 inside the mounting groove 204. The rotating block 208 is then rotated, causing the locking block 207 to rotate to the screw hole of the mounting foot on the sensor body 4. The pull rod 201 is then released, and the elastic force of the mounting spring 202 causes the rotating block 208 to descend, causing the locking block 207 to engage with the screw hole of the mounting foot on the sensor body 4. The bottom end of the locking block 207 engages with the inside of the locking hole 203. At the same time, the rubber sleeve 206 is used to improve the engagement and tightness between the surface of the locking block 207 and the inner wall of the screw hole, thereby achieving a firm and secure connection between the sensor body 4 and the three sliding seats 6. The suction cup 7 is used to further improve the adsorption and fixation between the back of the sensor body 4 and one end of the mounting seat 5, thereby enabling quick assembly and disassembly between the sensor body 4 and the mounting seat 5, avoiding the cumbersome and inconvenient assembly and disassembly caused by traditional bolt fixing.
