DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0021] like Figure 1-3 As shown, the utility model provides a portable gas analyzer, including a mobile base 1, a gas analyzer body 2, a mounting groove 3, a mobile device, and a stabilizing device. The gas analyzer body 2 is fixedly connected to the inside of the mobile base 1, the mounting groove 3 is opened at the bottom of the mobile base 1, and the mobile device and the stabilizing device are both arranged inside the mounting groove 3; the mobile device includes a motor 401, a transmission rod 402, a worm 403, a worm wheel 404, a rotating rod 405, a rotating column 406, and a mobile wheel 407; the motor 401 is fixedly connected to the outer wall of the mobile base 1, The transmission rod 402 is fixedly connected to the output end of the motor 401, and the other end of the transmission rod 402 is rotatably connected to the inner wall of the mounting groove 3 through a bearing. The worm 403 is fixedly sleeved on the outer wall of the transmission rod 402, and the worm wheel 404 is meshed with the upper end of the worm 403. Both ends of the transmission rod 402 are rotatably connected to the inner wall of the mounting groove 3 through bearings, and the worm wheel 404 is fixedly sleeved on the outer wall of the transmission rod 402. The rotating column 406 is fixedly sleeved on the outer walls on both sides of the transmission rod 402, and a moving wheel 407 is provided at the bottom of the end of the rotating column 406 away from the transmission rod 402.

[0022] There are two worms 403 , two worm wheels 404 , and two rotating rods 405 symmetrically disposed on the outer walls of both ends of the transmission rod 402 .

[0023] A handle 6 is provided on the outer wall of the mobile base 1 .

[0024] During use, when the gas analyzer body 2 needs to be moved, first lift the mobile base 1 through the handle 6, then start the motor 401 to drive the transmission rod 402 to rotate, and then drive the worm 403 to rotate, and then the worm gear 404 engaged therewith will also rotate, and then drive the rotating rod 405 to rotate, and then drive the rotating column 406 and the moving wheel 407 to rotate. When the rotating column 406 rotates to a vertical position, the mobile base 1 can be put down, and the mobile base 1 and the gas analyzer body 2 can be moved by the moving wheel 407.

[0025] In this embodiment, by setting up a moving device, the moving wheel 407 can be expanded or retracted by the rotation of the rotating column 406. When it is expanded, it is more convenient to move the gas analyzer body 2 without the need for handheld transfer, which saves a lot of manpower and further improves the convenience of the device. When it does not need to be moved, it can be retracted, thereby ensuring the stability of the mobile base 1 in cooperation with the stabilizing device. Example

[0026] like Figure 1-3 As shown, based on Example 1, the utility model provides a technical solution: preferably, the stabilizing device includes a thread groove 501, the thread groove 501 is opened on both sides of the outer wall of the rotating rod 405, and the outer walls on both sides of the rotating rod 405 are threadedly connected with a moving block 502 through the thread groove 501, and the lower end of the moving block 502 is hinged with a connecting rod 503 through a hinge seat, and the other end of the connecting rod 503 is hinged with a support seat 504.

[0027] One side outer wall of the moving block 502 is slidably connected to the inner wall of the mounting groove 3 .

[0028] The thread directions of the thread grooves 501 formed on the outer walls of both sides of the rotating rod 405 are opposite to each other.

[0029] In this embodiment, by providing a stabilizing device, when the rotating column 406 and the moving wheel 407 are unfolded, the support seat 504 will move upward. Conversely, when the rotating column 406 and the moving wheel 407 are retracted, the support seat 504 will move downward to provide support, thereby improving the stability of the gas analyzer body 2 during use.

[0030] During use, when the rotating rod 405 in the moving device rotates, the moving block 502 whose outer wall is threadedly connected by the thread groove 501 will move toward the middle or both sides at the same time, thereby driving the upper ends of the connecting rods 503 to move closer or farther away from each other, and then the connecting rods 503 will drive the support seat 504 at the bottom to rise or fall. When the rotating column 406 and the moving wheel 407 are expanded, the support seat 504 will move upward. Conversely, when the rotating column 406 and the moving wheel 407 are retracted, the support seat 504 will move downward to play a supporting role.
