Technical Field

The invention relates to the field of power distribution equipment, in particular to a distribution box.

Background

The distribution box is widely applied electrical equipment, the performance of the traditional distribution box sealing material is not good, so that the strength is not enough, gaps are too large, and the sealing performance is poor, the distribution box arranged outdoors is poor in waterproof performance, water enters the box, the humidity is high, the corrosion of electrical elements in the box and the corrosion damage life of the box body are reduced, and when the water enters seriously, the elements are damaged, the electrical short circuit is caused, the power failure accident is caused, and the normal power supply is influenced.

Therefore, the prior art provides a distribution box, and a rubber sealing ring is pasted on a box door or a box body, and the service life of the rubber sealing ring adhesive is effective, so that the rubber sealing ring is easy to fall off after being switched for many times, sealing failure is caused, and external water flow easily enters the distribution box to cause short circuit.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art. Therefore, the invention provides the distribution box which can effectively improve the waterproof performance of the distribution box.

According to one aspect of the invention, the distribution box comprises a box body and a box door, wherein a cable joint for a cable to pass through is arranged on the box body, a second flanging is arranged on the outer edge of the box door, a first flanging is arranged on the edge of an opening of the box body, and the second flanging can be matched with the first flanging.

Furthermore, a sealing ring is arranged on the first flanging, the sealing ring is located at the part where the first flanging is matched with the second flanging, and the sealing ring can block a gap between the first flanging and the second flanging.

Furthermore, the cable joint is a locking joint which can prevent water from entering the box body from the locking joint.

Further, the cable joint includes locking head and lock nut, is provided with the through wires hole that is used for wearing to establish the cable in the locking head, lock nut and locking head screw-thread fit, and the one end that lock nut kept away from the locking head is provided with the extrusion face, and the extrusion face can extrude the locking head and make the bore in through wires hole diminish.

Furthermore, the inner wall of the threading hole is provided with a rubber ring.

Furthermore, a boss is arranged on the locking head, an inner nut is sleeved on the locking head, the inner nut is in threaded fit with the locking head, and the inner nut and the boss can clamp the box body.

Furthermore, a locking device is arranged on the box door and used for locking the box body and the box door.

Furthermore, the locking device comprises a lock body, a lock cylinder and a lock tongue, the lock body is arranged on the box door in a penetrating mode, the lock cylinder penetrates through the lock body and is arranged in a rotatable mode relative to the lock body, and the lock tongue is fixedly arranged at one end of the lock cylinder.

Furthermore, one end of the lock body, which is far away from the lock tongue, is provided with a sealing gasket, and the sealing gasket is used for preventing water from entering the box body from the locking device.

Furthermore, the spring bolt is in a step shape, and the distance between one end of the spring bolt far away from the lock cylinder and the box door is smaller than the distance between one end of the spring bolt close to the lock cylinder and the box body.

By applying the distribution box, the first flanging is integrated with the box body, the second flanging is integrated with the box door body, the first flanging is firmly fixed with the box body, and the second flanging is firmly fixed with the box door, so that the situation that a sealing structure is not easy to fall off after multiple times of opening and closing is caused, and the sealing performance between the box door and the box body of the distribution box is effectively improved.
