In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0024] The distribution box door structure provided in the embodiment of the utility model with a large opening angle is as follows Figures 1 to 7 As shown, it includes a box body 1, a box cover 2 and a hinge 3, wherein the box cover 2 is movably connected to the box body 1 through the hinge 3; the hinge 3 includes a connector 31, and a pin A32 and a pin B33 respectively provided at the first end and the second end of the connector 31; the box cover 2 is provided with a connecting seat A21 movably connected to the pin A32, and the inner side wall of the box body 1 is provided with a connecting seat B11 movably connected to the pin B33, and the connecting seat B11 is provided with a vertical direction (i.e. Figure 3The outer end of the pin shaft B33 extends into the limiting slide groove 12 and can slide up and down in the limiting slide groove 12; the connecting body 31 is a C-shaped structure, and the upper notch 310 is used to avoid the side wall edges of the box body 1 and the box cover 2 when the box cover 2 is opened to the maximum angle. This design allows the box cover 2 of the distribution box to be opened at a large angle (up to 180 degrees) when opened, thereby avoiding the operational inconvenience caused by the difficulty in opening the box cover 2 at a large angle; through the connection of the pin A32 and the pin B33, the box cover 2 is firmly connected to the box body 1, and the pin B33 can slide up and down in the limiting slide groove 12 without separating from the limiting slide groove 12, so as to adapt to the large-angle opening of the box cover 2 and the box cover 2 will not separate from the box body 1 after opening, and the connector 31 is designed as a C-shaped structure to play an avoidance role when the box cover 2 is opened to the maximum angle, thereby avoiding the occurrence of collision between the box cover 2 and the box body 1. The overall design is reasonable and easy to operate, which effectively improves the availability of the distribution box.
[0025] like Figure 4 and Figure 5 As shown, one end of the pin shaft A32 is provided with an end head 321 with an increased diameter, and the other end is provided with an elastic snap buckle 322. The connecting seat A21 is provided with a socket A211, and the corresponding end of the connecting body 31 is provided with a socket B311. The pin shaft A32 passes through the socket A211 and the socket B311 and is axially limited from both ends by the end head 321 and the elastic snap buckle 322. This design allows the connecting body 31 to rotate around the axis of the pin shaft A32 relative to the box cover 2, and the axial limitation of the pin shaft A32 is achieved by the cooperation of the end head 321 and the elastic snap buckle 322, ensuring that the pin shaft A32 will not fall off during use, thereby increasing the reliability of the hinge 3.
[0026] Continue to read Figure 4 and Figure 5 As shown, the second end of the connecting body 31 is provided with a through axial hole 312, and the two pin shafts B33 and the spring 34 located between the two pin shafts B33 are passed through the axial hole 312. The two pin shafts B33 are kept away from each other under the elastic force of the spring 34 and respectively cooperate with the limiting slide groove 12 on the corresponding side, so as to ensure that the pin shaft B33 can maintain an effective connection between the connecting body 31 and the connecting seat B11. During assembly, the pin shaft B33 can be retracted into the axial hole 312 first. After the outer end of the pin shaft B33 is aligned with the position of the limiting slide groove 12, the end of the pin shaft B33 is inserted into the corresponding limiting slide groove 12 through the elastic force of the spring 34.
[0027] In some embodiments, in order to improve the convenience of operation, an axial opening 35 is provided on the side wall of the shaft hole 312 at a position corresponding to the two pin shafts B33, and a limiting shaft 36 is inserted into the axial opening 35 and fixedly connected to the pin shaft B33. When the connector 31 is connected to the box body 1, the pin shaft B33 can be retracted into the shaft hole 312 by pressing the limiting shaft 36, which is convenient to operate. When the pin shaft B33 moves in the shaft hole 312, the limiting shaft 36 moves in the axial opening 35.
[0028] like Figure 2 As shown, a plurality of screw holes 22 are arranged at intervals around the box cover 2, and screw holes 13 are provided at positions corresponding to the screw holes 22 on the periphery of the box body 1. The fastening screws pass through the screw holes 22 and cooperate with the screw holes 13. This structural design can ensure a firm connection between the box cover 2 and the box body 1, avoiding the problem of loosening or falling off during use.
[0029] In some embodiments, a sealing ring (not shown in the figure) is provided between the box body 1 and the box cover 2, and the sealing ring is used to seal the gap between the box body 1 and the box cover 2 to prevent dust and water. In order to position the sealing ring, an annular sealing groove can be provided on the box body 1 or the box cover 2, and the sealing ring is embedded in the sealing groove.
[0030] Furthermore, the box body 1 is provided with a connecting seat B11 on both sides, and the box cover 2 is provided with a corresponding connecting seat A21 on both sides. The connecting seat B11 on one side of the box body 1 is connected to the connecting seat A21 on the corresponding side of the box cover 2 through the hinge 3. In this way, the box cover 2 can be designed as a left-opening door structure or a right-opening door structure according to user needs during production.
[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
