Description

Technical Field

[0001] The utility model relates to the technical field of electric control boxes, in particular to an automatic electric control box. Background Art

[0002] The electrical control box is an auxiliary device used to centrally install various electrical control components and other parts, and is used to control and detect the operating status of the corresponding electrical equipment. It is widely used inside and outside various buildings and in urban power grids. The existing electrical control box is generally equipped with an openable front panel, on which various electrical control components are installed. The control box is also equipped with wiring terminals for realizing electrical connection between electrical control components and electrical equipment.

[0003] When using a traditional control box, electrical control components need to be installed inside before using the control box, but the traditional control box can only open the front door, and then the electrical control components can be installed through the front door. Due to the limited opening range of the front door of the control box, it is more difficult to install the electrical control components in traditional equipment, which in turn leads to a slower installation progress and is more time-consuming and labor-intensive. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an automated electrical control box, which has the advantages of easy installation and convenient use, and solves the problems raised by the above-mentioned background technology.

[0010] As a preferred technical solution of the utility model: the outer wall of the rotating knob contacts the outer wall of the fixed cylinder, and the static length of the driving spring is greater than the inner cavity length of the fixed cylinder.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The automatic electrical control box realizes the installation of the top cover and the box body by means of a fixing tube, a telescopic rod and a driving spring arranged on the outer wall of the top cover.

[0022] By means of a junction box 9 arranged on the outer wall of the box body 1 and a limit plate 10 rotatably connected to the inner cavity of the junction box 9, when wiring the electric control equipment in the inner cavity of the box body 1, the cable is passed through the inner cavity of the junction box 9. After the connection is completed, the limit plate 10 is rotated, and the outer wall of the cable can be fixed under the action of the outer wall of the limit plate 10, so that the cable has good stability when in use.

[0023] In a preferred embodiment, the outer wall diameter of the telescopic rod 6 near the limiting hole 4 matches the inner wall diameter of the limiting hole 4 , and the outer wall diameter of the telescopic rod 6 near the limiting hole 4 is larger than the outer edge diameter of the driving spring 7 .

[0024] By arranging the telescopic rod 6 and the driving spring 7 in the inner cavity of the fixed cylinder 5, the driving spring 7 is restricted in the inner cavity of the fixed cylinder 5 under the action of the outer wall of the telescopic rod 6 and the inner wall of the fixed cylinder 5, so that the telescopic rod 6 is driven under the action of the driving spring 7, and then the telescopic rod 6 enters the inner cavity of the limiting hole 4, thereby achieving the effect of assembling the top cover 3 and the box body 1.

[0025] In a preferred embodiment, a mounting groove is provided at the bottom of the top cover 3 , and the shape and size of the inner wall of the mounting groove matches the shape and size of the top of the box body 1 .

[0026] Through the installation groove opened at the bottom of the top cover 3, when the top cover 3 is installed on the top of the box body 1, the top of the box body 1 will enter the inner cavity of the top cover 3, and then the top cover 3 and the box body 1 will be connected under the action of the telescopic rod 6, thereby realizing the assembly of the top cover 3 and the box body 1.

[0027] In a preferred embodiment, there are two limit plates 10 , and the two limit plates 10 are rotatably connected in the inner cavity of the junction box 9 .

[0028] By respectively setting the limit plates 10 on both sides of the inner cavity of the junction box 9, after the cable passes through the inner cavity of the junction box 9, the limit plates 10 on both sides are then rotated so that the outer walls of the limit plates 10 contact the outer walls of the cables after rotation, thereby fixing the cables and ensuring the stability of the cables when in use.

[0029] In a preferred embodiment, the ash absorbing block 11 is made of polyvinyl alcohol, and the ash absorbing blocks 11 are installed on both sides of the inner cavity of the junction box 9 .

[0030] By installing the dust absorption block 11 in the inner cavity of the junction box 9, after the cable is installed in the inner cavity of the junction box 9, the outer wall of the dust absorption block 11 made of polyvinyl alcohol will be in close contact with the outer wall of the cable, thereby preventing dust from entering the inner cavity of the box body 1 from the junction box 9 during the use of the cable, thereby preventing damage to the electronic components in the inner cavity of the box body 1.

[0031] In a preferred embodiment, the outer wall of the rotating knob 8 contacts the outer wall of the fixing cylinder 5 , and the static length of the driving spring 7 is greater than the inner cavity length of the fixing cylinder 5 .

[0032] By setting a rotating knob 8 on the outer wall of the fixed tube 5, and the outer wall of the rotating knob 8 being rotatably connected to the outer surface of the telescopic rod 6, when the rotating knob 8 is rotated upward, the telescopic rod 6 will be pulled out of the inner cavity of the limiting hole 4 under the action of the rotating knob 8, thereby achieving the unlocking effect, and then the top cover 3 is removed from the top of the box body 1.

[0033] Working principle: when the above device is in use, when it is necessary to install the electric control device in the inner cavity of the box body 1, the outer wall of the rotating knob 8 is pulled to rotate the rotating knob 8, so that during the rotation of the rotating knob 8, the telescopic rod 6 is pulled outward, and the telescopic rod 6 will move out of the inner cavity of the box body 1. At this time, the top cover 3 can be removed from the top of the box body 1, and then the box door 2 is rotated and opened from the outer wall of the box body 1. At this time, the installation work can be carried out very conveniently from the top and side of the box body 1 at the same time, making the installation work easier and more convenient. After the electronic control equipment is installed, the limit plate 10 is rotated again so that the limit plates 10 on both sides in the inner cavity of the junction box 9 are flipped upwards, and then the cable is placed from the junction box 9 into the inner cavity of the box body 1 to complete the wiring work, and then the limit plate 10 is rotated again so that the limit plate 10 is flipped downward. During the flipping process of the limit plate 10, the outer wall of the limit plate 10 can achieve a clamping and limiting effect on the outer wall of the cable, and during the use of the cable, the dust absorption block 11 can prevent external dust and debris from entering the inner cavity of the box body 1 through the junction box 9.
