Description

Technical Field

[0001] This utility model relates to the field of electrical box technology, and more specifically to an adjustable inner door structure for a double-door electrical box. Background Technology

[0002] A distribution box is a set of switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment assembled in a closed or semi-closed metal cabinet or enclosure according to electrical wiring requirements. For example, Chinese Patent No. CN 205212266U discloses a double-layer low-voltage distribution box, including a box body, an outer door, and an inner door. The outer door has two outer door hinges, which connect to the box body through the cooperation of outer door hinge A and two outer door hinges B located on the box body. Tempered glass is installed on the outer door. The inner door is installed on the box body via hinges and is located between the outer door and the box body. The box body has upper and lower inner door frames and left and right inner door frames that match the inner door, and handles are provided on both sides of the box body. The existing distribution boxes have switches, meters, and other equipment installed on the inner door, while the main electrical components are installed inside the box behind the inner door, which is a safer arrangement. However, the hinge position of the existing inner door is fixed, and the distance between the inner and outer doors is fixed at the factory and cannot be adjusted. Some instruments are too large to be accommodated by the existing double-layer distribution boxes. In order to install them on the inner door, a distribution box with a specially customized inner door position is required. Therefore, the existing distribution boxes have poor adaptability. Utility Model Content

[0003] In view of this, the present invention provides an adjustable inner door structure for a highly adaptable double-layer door electrical box.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable inner door structure for a double-door electrical box, the electrical box having an outer door and an inner door, the inner door having a door frame and a door body, the door body being hingedly connected to the door frame, comprising:

[0006] The bracket consists of two sets, which are respectively fixed on two opposite inner side walls of the electrical box, and the bracket is provided with self-tapping screw holes;

[0007] The adjusting plate consists of two sets, which are respectively fixed on two opposite vertical beams of the door frame, and the adjusting plate has a strip hole.

[0008] The self-tapping screws are in two sets, each passing through a corresponding slot and threaded into a corresponding self-tapping screw hole.

[0009] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an adjustable inner door structure for a double-door electrical box. By moving the adjustment plate, the position of the inner door can be adaptively adjusted according to the size of the electrical components to be installed in the box. That is, the distance between the inner and outer doors is adjustable, as is the depth of the electrical box. Therefore, the electrical box can be adapted to install electrical components of various sizes, with high adaptability. The inner door separates the box, which improves the safety factor of the distribution box and also improves the ease of use of the equipment.

[0010] Furthermore, the adjusting plate has multiple screw holes, which are connected in sequence to form the strip-shaped hole.

[0011] Furthermore, two adjacent screw-through holes are connected by a notch, the width L of which is smaller than the diameter R of the screw-through hole, thereby forming a wavy limiting hole wall on the inner surface of the strip hole.

[0012] The beneficial effect of adopting the above technical solution is that after the self-tapping screw passes through the screw through hole, the self-tapping screw can be stuck in the screw through hole, thereby fixing the position of the adjusting plate. This avoids the problem of the adjusting plate being displaced due to vibration of the vertical beam when using a strip hole with a straight inner wall.

[0013] Furthermore, the vertical beam is provided with a knockable pre-reserved block, which, when knocked off, exposes a pre-reserved hole for wiring.

[0014] The beneficial effects of adopting the above technical solution are as follows: when there is a reserved block on the vertical beam, the reserved hole is closed by the reserved block when no additional wiring is needed, which improves the aesthetics of the door frame. When additional wiring is needed, such as when there are instrument indicator lights on the outer door that need to be wired, or when grounding wires need to be run, the reserved block can be knocked off to expose the reserved hole.

[0015] Furthermore, the adjusting plate has a mounting flange, which is fixedly connected to the vertical beam by fastening screws. Attached Figure Description
