Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-3 As shown, this utility model provides a technical solution: an adjustable length air volume controller, including a receiving box 1, a controller body 11 fixedly installed on the inner side of the receiving box 1, a horizontal frame 12 fixedly installed on one end of the receiving box 1, a double-ended lead screw 13 rotatably installed on the inner side of the horizontal frame 12, symmetrically distributed movable screw plates 14 threaded on the outer side of the double-ended lead screw 13, symmetrically distributed connecting blocks 15 fixedly installed on one end of each movable screw plate 14, a first locking post 16 fixedly clamped on the opposite end of each connecting block 15, a diagonal rod 17 rotatably sleeved on the outer side of each first locking post 16, a connecting seat 19 provided on the opposite end of each diagonal rod 17, a symmetrically distributed second locking post 18 fixedly clamped on one end of each connecting seat 19, a second locking post 18 rotatably sleeved on the opposite end of each diagonal rod 17, an installation plate 20 fixedly connected to one end of the connecting seat 19, a motor 21 fixedly installed on the outer side of the horizontal frame 12, and the drive end of the motor 21 fixedly connected to the double-ended lead screw 13.

[0020] The upper part of the receiving box 1 is provided with symmetrically distributed upper protective plates 22. One end of each upper protective plate 22 is fixedly fitted with an upper horizontal column 23. The outer side of each upper horizontal column 23 is rotatably sleeved with an inclined protective plate 24. The opposite end of the inclined protective plate 24 is rotatably installed with a connector 25. The top of the receiving box 1 is fixedly installed with an array of dampers 26. The top of the dampers 26 is fixedly connected to the upper protective plate 22.

[0021] By adopting the above technical solution, the upper part of the device is protected by setting the inclined guard plate 24 to rotate on the upper horizontal column 23, and by combining the action of the connecting piece 25 with the effect of the damper 26, so as to prevent the controller body 11 from being directly hit, thereby effectively protecting the safety of the controller body 11.

[0022] A guide plate 27 is fixedly mounted on the inner side of the horizontal frame 12, and one end of the movable screw plate 14 is slidably sleeved on the outer side of the guide plate 27.

[0023] By adopting the above technical solution, the moving wire plate 14 is guided by setting the guide plate 27.

[0024] The outer side of each first locking post 16 is fixedly fitted with symmetrically distributed limiting rings 28, with one end of the limiting ring 28 abutting against the inclined rod 17.

[0025] By adopting the above technical solution, the movement of the diagonal rod 17 is limited by setting a limiting ring 28.

[0026] A spring 29 is fixedly installed at one end of each damper 26, and the top of the spring 29 is fixedly connected to the upper guard plate 22.

[0027] By adopting the above technical solution, the damping effect of the damper 26 is enhanced by setting the spring 29.

[0028] The side end of the receiving box 1 is fixedly equipped with symmetrically distributed L-shaped handles 30.

[0029] By adopting the above technical solution, the equipment can be easily moved and transported using the L-shaped handle 30.

[0030] Working principle: First, when the length of this equipment needs to be adjusted, the double-ended lead screw 13 is rotated by the motor 21. The double-ended lead screw 13 rotates on the horizontal frame 12, causing the moving lead plate 14 to move relative to each other. The moving lead plate 14 moves the connecting block 15 and the first locking post 16. The first locking post 16 controls the movement of the inclined rod 17. The two ends of the inclined rod 17 move on the first locking post 16 and the second locking post 18 to push the connecting seat 19 and the mounting plate 20, thereby extending the mounting plate 20. This also allows for length adjustment of the receiving box 1 and the controller body 11, enabling them to better adapt to different installation spaces and pipeline layout requirements, making them quite practical. The inclined guard plate 24 rotates on the upper horizontal column 23, and with the action of the connecting piece 25 and the effect of the damper 26, the top of this equipment is protected to prevent the controller body 11 from being directly bumped, thus effectively protecting the safety of the controller body 11.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
