[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a pull-out electric control box. Figure 1-5 As shown, the retractable electric control box includes an electric control box 1, a fan structure 2 fixedly arranged on the top of the electric control box 1, and a retractable structure 3 arranged in the electric control box 1; the retractable structure 3 includes a plurality of retractable boxes 31 which move laterally in the electric control box 1 and are distributed in a linear array, a sliding member 32 arranged at the bottom of the retractable box 31, and a locking member 33 arranged at a position corresponding to the retractable box 31 in the electric control box 1.

[0028] When in use, the pull-out box 31 is fixed in the electric control box 1 by the locking piece 33, and drives the fan structure 2 arranged on the top of the electric control box 1 to dissipate heat for the modules in the electric control box 1; when it is necessary to pull the pull-out box 31 to maintain the modules placed in the pull-out box 31, drive the locking piece 33 and then pull the pull-out box 31, so that the pull-out box 31 slides on the sliding piece 32.

[0029] Specifically, the locking member 33 includes a round rod 331 fixedly arranged on the electric control box 1, a first protrusion 332 fixedly arranged at the end of the round rod 331 away from the electric control box 1, a second protrusion 333 slidably mounted on the round rod 331, a fixed seat 334 fixedly arranged on the side of the pull-out box 31 close to the first protrusion 332, a clamping plate 335 symmetrically slidably arranged on the fixed seat 334, and a tension spring 336 arranged between the fixed seat 334 and the clamping plate 335, and the two ends of the tension spring 336 are respectively fixedly connected to the clamping plate 335 and the fixed seat 334.

[0030] When fixing the pull-out box 31, the pull-out box 31 is pushed to slide in the electric control box 1, so that the clamping plate 335 slidingly arranged on the fixing seat 334 contacts the first protrusion 332 under the action of the tension spring 336 until it abuts against the side of the first protrusion 332 close to the round rod 331, thereby fixing the pull-out box 31 in the electric control box 1.

[0031] Furthermore, the locking member 33 further includes a compression spring group 337 symmetrically arranged on the electric control box 1 and located on both sides of the round rod 331 , and an abutment plate 338 respectively fixedly arranged on one end of the compression spring group 337 away from the electric control box 1 .

[0032] When the drawer box 31 needs to be pulled, the drawer box 31 is pushed so that the clamping plate 335 contacts the side of the second protrusion 333 under the force of the tension spring 336 until it abuts against the side of the second protrusion 333 close to the round rod 331. The drawer box 31 is released and the abutting plate 338 pushes the drawer box 31 to slide in the electric control box 1 under the force of the compression spring group 337 until the first protrusion 332 is no longer in contact with the clamping plate 335, so that the drawer box 31 can be pulled.

[0033] Furthermore, a slide rail 3341 is provided on the fixing seat 334, and the card plate 335 is slidably arranged in the slide rail 3341; when the card plate 335 contacts the sides of the first protrusion 332 and the second protrusion 333, the card plate 335 slides on the slide rail 3341, thereby guiding the movement of the card plate 335.

[0034] Furthermore, a slope 3351 that contacts the first protrusion 332 is provided on one side of the card plate 335 that is close to each other; when the card plate 335 is engaged with the first protrusion 332 and the second protrusion 333, the slope 3351 on the card plate 335 contacts the first protrusion 332 and the second protrusion 333, which facilitates the card plate 335 to be engaged with the first protrusion 332 and the second protrusion 333.

[0035] Among them, in order to facilitate the sliding guidance of the pull-out box 31 in the electric control box 1 and support the pull-out box 31, the sliding member 32 includes a sliding plate 321 symmetrically fixedly arranged at the bottom of the pull-out box 31 and a support plate 322 symmetrically fixedly arranged on the electric control box 1 and slidably connected to the sliding plate 321; by making the sliding plate 321 arranged at the bottom of the pull-out box 31 slide on the support plate 322, the sliding plate 321 is guided, thereby guiding the pull-out box 31, and by fixing the support plate 322 on the electric control box 1, the pull-out box 31 is supported.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
