Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, in particular to a distribution box. Background Art

[0002] The distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. For external distribution boxes, workers must remember to close the door of the distribution box after completing their work in the distribution box. Once the workers fail to close the door after completing their work or the door is blown open by the wind in windy weather, some dirt or small animals will enter the distribution box, and then the transformer and low-voltage switch in the box will trip, which will not only affect the normal use of the circuit, but also increase the workload of relevant workers, and there are certain safety hazards.

[0003] For example, the utility model patent with the authorization announcement number CN 202488001 U discloses a distribution box that can automatically close the door, including a box body fixed on a pole and a box door rotatably connected to the box body, and the box door is connected to the box body through a spring hinge to achieve automatic closing of the distribution box. However, due to the effect of the spring hinge, the opening angle of the distribution box is limited. When the staff is repairing or replacing the components inside the distribution box, the door will automatically close, affecting the staff's operation. Utility Model Content

By adjusting the closing speed of the first door and the second door, the box doors on both sides are closed in turn, thereby achieving the effect of automatic closing.

[0005] A distribution box comprises a box body and a first box door and a second box door respectively installed on both sides of the box body, wherein the first box door and the second box door are movably connected to the box body through adjustable torque hinges; wherein a shielding sheet is provided on the side of the first box door opposite to the side on which the first box door is installed; and the damping force of the adjustable torque hinge of the first box door is smaller than the damping force of the adjustable torque hinge of the second box door.

[0006] Preferably, the setting range of the automatic closing angle of the adjustable torque hinge of the first door is ≤90°.

[0007] Preferably, the setting range of the automatic closing angle of the adjustable torque hinge of the second door is ≤90°.

[0008] Preferably, the setting range of the hovering angle of the adjustable torque hinge of the second door is >90°.

[0009] Preferably, when the first door and the second door are both closed, the second door is located outside the shielding sheet.

[0010] Preferably, a positioning hook is provided inside the distribution box, the positioning hook includes a hook rod and a hook head, a positioning ring is provided on the inner side of the second box door, the hook head is plugged into the positioning ring; an installation hole is provided on the bottom surface of the box body, the hook rod is plugged into the installation hole.

[0011] Preferably, it also includes a support frame fixedly installed under the box body for supporting the box body.

[0012] Preferably, the support frame includes a support rod fixedly connected to the box body for supporting the box body.

[0013] Preferably, a plurality of support rods are provided, and a crossbeam is horizontally arranged between two adjacent support rods.

[0014] The utility model has the following beneficial effects:

[0015] (1) The box body and the door are connected by a hinge with adjustable torque. By adjusting the closing speed of the first door and the second door, the doors on both sides are closed in sequence, thereby achieving the effect of automatic closing, preventing the staff from forgetting to close the door due to negligence and causing safety accidents;

[0016] (2) By adjusting the torque of the hinge, the door can automatically remain stable when opened to a certain angle and will not close automatically;

[0017] (3) By providing a positioning hook on the box body and a positioning ring for accommodating the positioning hook on the second box door, the box door can be kept open, which is convenient for operators to work for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the embodiments of the utility model and the accompanying drawings 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 of 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.

[0023] In the description of the present invention, it should be noted that the terms, "upper", "lower", "inside", "outside", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] A distribution box, such as Figure 1 As shown, it includes a rectangular box 1 and a support frame 2, and the box 1 is fixedly installed above the support frame 2. The support frame 2 includes four support rods 21 and four cross beams 22 arranged below the box 1, and the four cross beams 22 are arranged horizontally and connected between two adjacent support rods 21 respectively.

[0025] The box body 1 is provided with two doors, namely, a first door 11 and a second door 12, which are respectively installed on both sides of the box body 1, and both doors can rotate relative to the box body 1. A shielding sheet 111 is provided on the side of the first door 11 opposite to the side on which it is installed. When both doors are closed, the second door 12 is located on the outside of the shielding sheet 111. Such a setting can maximize the sealing of the box body 1 and prevent light, water and pollutants from entering the distribution box through the gap between the first door 11 and the second door 12.

[0026] The first door 11 and the second door 12 are both movably connected to the box body 1 through the adjustable torque hinge 13. In this embodiment, the automatic closing angle of the adjustable torque hinge 13 is not greater than 90°, that is, when the opening angle of the two doors is not greater than 90°, the two doors can be automatically closed. By adjusting the torque of the hinge, the damping force applied by the hinge to the door can be changed, thereby adjusting the closing speed of the two doors. The greater the damping force applied by the hinge to the door, the slower the closing speed of the door.

[0027] Because a shielding piece 111 is provided at the first door 11, the first door 11 needs to be closed first when the door is closed, that is, the closing speed of the first door 11 is greater than that of the second door 12, so the hinge needs to be adjusted so that the damping force of the adjustable torque hinge 13 of the first door 11 is less than the damping force of the adjustable torque hinge 13 of the second door 12.

[0028] When the staff needs to use the distribution box briefly, in order to avoid the box door automatically closing and interfering with the work when the staff is working, the torque of the hinge installed on the second box door 12 can be adjusted so that when the opening angle of the second box door 12 is greater than 90°, such as 95°, it can be automatically positioned, that is, the box door can hover when it reaches this position and will no longer close automatically.

[0029] Furthermore, when the staff needs to use the distribution box for a long time, in order to prevent the box door from automatically closing and interfering with the work when the staff is working, a positioning hook is provided in the box body 1, and the positioning hook includes a hook rod and a hook head connected in one piece. To install the hook rod, a mounting hole is provided at the bottom surface of the box body 1, and one end of the hook rod is inserted into the mounting hole and can rotate in the mounting hole. In addition, a positioning ring is provided on the inner side of the second box door 12. When the second box door 12 needs to be kept open for a long time, the hook head can be placed in the positioning ring to facilitate the staff's operation.
