Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1 to 3, the present embodiment provides a high-voltage electrical box with a flip lock, which includes a housing. The housing includes a housing body 2 and an upper cover 1 connected to each other. The upper cover 1 is a PP material cover body, and includes a first cover body portion 11, a second cover body portion 12 and a locking piece 13. The first cover part 11 and the second cover part 12 are hinged to each other to form a flip structure, wherein the first cover part 11 is fixedly connected with the housing body 2 in a sealing manner, and the second cover part 12 is a foldable part. The locking piece 13 is provided between the first lid portion 11 and the second lid portion 12, and plays a role of supporting the second lid portion 12 after being opened. The latch 13 includes a slant sinking groove 131 and a flap 132. The inclined sink groove 131 includes a bottom plate and two triangular side plates provided at one end of the second lid portion 12; a notch is arranged on the first cover body part 11, one end of the folded plate 132 is inserted into the notch, and is flexibly connected with the bottom edge of the notch; the other end of the flap 132 flexibly connects to the floor of the inclined sink 131. The flexible connection is made by a bendable thin plastic sheet. The number of the connecting members 14 may be plural, and 1 single connecting member is selected in this embodiment.

The first cover portion 11, the second cover portion 12 and the locking piece 13 are of an integral structure and are manufactured in an integral molding mode.

The bending angle of the folding plate 132 is generally 130-160 degrees, preferably 145 degrees in the embodiment, and can achieve the best supporting effect.

In this embodiment, the first lid portion 11 and the second lid portion 12 are connected by a plurality of connecting pieces 14 in a folded manner, each connecting piece 14 includes two fixing pieces that are flexibly connected, and the two fixing pieces are respectively connected to the first lid portion 11 and the second lid portion 12. The number of connecting elements 14 is at least 3, preferably 4 in this embodiment.

When the first lid portion 11 and the second lid portion 12 are in the same plane in normal use, one end surface of the flap 132 is parallel to the first lid portion 11, and the other end surface is obliquely downward connected to the bottom plate of the inclined sinker 131. When it is desired to open the overcap 1, as shown in figures 4 and 5, the flap 132 is flipped up about the edge joining the first cap portion 11 so that both end faces are above the plane of the first cap portion 11 until the floor of the inclined sink 131 and one end face of the flap 132 are folded together to provide a stop and support for the flipping of the second cap portion 12. This structure enables the second lid 12 to be erected at a certain angle after being turned up, and prevents the second lid from completely covering the upper surface of the first lid 11 and pressing the circuit.
