[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] A gas concentration balancer that is easy to install: It includes a balancer body 1. A pipe joint 11 is fixedly connected to the surface of the balancer body 1. An installation mechanism is provided on the surface of the balancer body 1. The installation mechanism includes a mounting plate 2. The mounting plate 2 is arranged on the back of the balancer body 1. A fixed block 21 is fixedly connected to the surface of the mounting plate 2. A bi-directional lead screw 22 is rotatably connected to the surface of the fixed block 21. A knob 23 is fixedly connected to the surface of the bi-directional lead screw 22. A guide rod 24 is fixedly connected to the surface of the fixed block 21. A moving block 25 is threadedly connected to the surface of the bi-directional lead screw 22. An adjusting rod 26 is fixedly connected to the surface of the moving block 25. A movable frame 3 is rotatably connected to the surface of the adjusting rod 26. A spring 31 is fixedly connected to the surface of the movable frame 3. A connecting rod 32 is fixedly connected to the surface of the spring 31. A limiting rod 33 is fixedly connected to the surface of the connecting rod 32. The balancer body 1 is snap-fitted to the surface of the movable frame 3. The balancer body 1 is installed on the wall through the mounting plate 2. By changing the distance between the balancer body 1 and the mounting plate 2, the distance between the balancer body 1 and the wall is changed, which facilitates the installation of the balancer body 1, making the installation work time-saving and labor-saving. At the same time, the balancer body 1 can be directly removed from the movable frame 3, which is convenient for the maintenance work of the balancer body 1.

[0024] Further, mounting holes are formed on the surface of the mounting plate 2. The mounting holes on the mounting plate 2 cooperate with screws to mount the mounting plate 2 on the wall surface. There are two sets of fixing blocks 21 which are respectively located on both sides of the mounting plate 2. There are two sets of guide rods 24 which are parallel to each other. The guide rods 24 are fixedly connected to the surface of the mounting plate 2 through the fixing blocks 21. The guide rods 24 are symmetrically distributed on the fixing blocks 21. The moving block 25 is at the central position of the fixing block 21, and the moving block 25 and the guide rods 24 are parallel to each other.

[0025] Further, threaded holes and circular holes are formed on the surface of the moving block 25. The bidirectional lead screw 22 is threadedly connected to the threaded hole of the moving block 25. The moving block 25 slides on the surface of the guide rod 24 through the circular hole. The moving block 25 slides on the surface of the mounting plate 2 through the guide rod 24.

[0026] Further, there are two sets of moving blocks 25, and the sliding directions of the two sets of moving blocks 25 are opposite. The rotation directions of the adjusting rods 26 on different moving blocks 25 are opposite.

[0027] Further, the movable frame 3 and the mounting plate 2 are parallel to each other. There are two sets of adjusting rods 26, and the two sets of adjusting rods 26 are respectively rotatably connected to both sides of the movable frame 3. Each set of adjusting rods 26 has two adjusting rods 26, and there are four adjusting rods 26 in total. The moving block 25 drives the movable frame 3 to horizontally move on the mounting plate 2 through the two sets of adjusting rods 26. The movable frame 3 drives the balancer body 1 to horizontally move on the mounting plate 2, thereby changing the distance between the balancer body 1 and the mounting plate 2.

[0028] Further, a card slot is formed on the surface of the movable frame 3. The balancer body 1 is snap-fitted to the card slot of the movable frame 3. The card slot of the movable frame 3 limits the mounting position of the balancer body 1 on the movable frame 3. A guide hole is formed on the surface of the movable frame 3. The limiting rod 33 slides on the guide hole of the movable frame 3. The card slot of the movable frame 3 is communicated with the guide hole of the movable frame 3. The limiting rod 33 slides on the guide hole of the movable frame 3 to the card slot of the movable frame 3.

[0029] Further, limiting grooves are formed on both sides of the balancer body 1. The elastic force of the spring 31 acts on the limiting rod 33 through the connecting rod 32. The limiting rod 33 is inserted into the limiting groove of the balancer body 1. The limiting rod 33 limits the position of the balancer body 1 on the movable frame 3 through the limiting groove of the balancer body 1. The balancer body 1 can be removed from the movable frame 3 for maintenance.

[0030] Working principle: Rotate the bidirectional lead screw 22 on the surface of the fixed block 21 through the knob 23. The bidirectional lead screw 22 drives two sets of moving blocks 25 to slide on the surface of the mounting plate 2 through rotation. The moving blocks 25 drive the movable frame 3 to slide horizontally on the surface of the mounting plate 2 through two sets of adjusting rods 26. The movable frame 3 drives the balancer body 1 to slide horizontally on the mounting plate 2, thereby changing the horizontal distance between the balancer body 1 and the mounting plate 2, and further changing the mounting distance of the balancer body 1 on the wall surface, ensuring the mounting distance of the balancer body 1 and making the installation of the balancer body 1 time-saving and labor-saving.

[0031] Pull the connecting rod 32 on the movable frame 3. The connecting rod 32 drives the limiting rod 33 to slide on the surface of the movable frame 3. The limiting rod 33 slides out from the limiting groove of the balancer body 1, and the limiting rod 33 cancels the restriction on the balancer body 1. At this time, the balancer body 1 can be removed from the card slot of the movable frame 3 without removing the screws from the wall surface to maintain the balancer body 1. Removing the balancer body 1 from the movable frame 3 facilitates the maintenance work of the balancer body 1.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
