[0034] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model.
[0035] Embodiment 1
[0036] Please refer to Figures 1 to 4 , the low-voltage power distribution cabinet for preventing the cabinet door from falling, comprising a cabinet body 1 and a cabinet door 2. The front side of the cabinet body 1 is open for installing and containing various electrical components. The cabinet door 2 is used to close the opening to protect the internal components from external interference.
[0037] Figure 2 and Figure 3 As shown in the figure, the side edge of the cabinet door 2 is provided with a first hinge 21, a second hinge 22 and a third hinge 23 along the up-down direction. Specifically, the first hinge 21 is located at the top end of the cabinet door 2, the third hinge 23 is located at the lower end of the cabinet door 2, and the second hinge 22 is located between the first hinge 21 and the third hinge 23. Importantly, the distance between the first hinge 21 and the second hinge 22 is less than the distance between the second hinge 22 and the third hinge 23. Such design makes the weight distribution of the cabinet door 2 more reasonable when it is opened, reducing the falling tendency of the suspended end.
[0038] The other side of the cabinet door 2 is provided with a first locking block 24, and the side of the cabinet body 1 is correspondingly provided with a second locking block 11. The first locking block 24 and the second locking block 11 are both provided with a locking hole, and a locking pin (not shown in the figure) is arranged in the locking hole. When the cabinet door 2 is closed, the locking pin is inserted into the locking holes of the first locking block 24 and the second locking block 11, which can effectively prevent the cabinet door 2 from falling due to its weight, thereby ensuring the stability and service life of the cabinet door 2.
[0039] Further, the top of the cabinet door 2 is provided with an upper mounting hole 25 on the same side as the first locking block 24. A turn latch 3 is arranged in the upper mounting hole 25, and the inner wall of the cabinet body 1 is provided with a support member for supporting the turn latch 3 in the locked state. In this way, when the turn latch 3 is locked, not only the locking safety of the cabinet door 2 can be improved, but also the cabinet door 2 can be provided with additional support force by the support member, thereby further preventing it from falling.
[0040] Embodiment 2
[0041] Based on the embodiment 1, please refer to Figure 2 and Figure 4 The turn latch 3 includes a lock body 31 and a lock plate 32. The lock body 31 is arranged in the upper mounting hole 25, and the lock plate 32 is located on the inner side of the cabinet door 2. The support member specifically includes a support block 12 arranged on the inner wall of the cabinet body 1. In the locked state of the turn latch 3, the lock plate 32 is supported on the support block 12, thereby supporting the cabinet door 2 and effectively preventing it from falling.
[0042] In addition, the bottom of the cabinet door 2 is also provided with a lower mounting hole 26 on the same side as the first locking block 24. The lower mounting hole 26 is also provided with a turn latch 3, and the inner wall of the cabinet body 1 is also provided with a corresponding support member for supporting the turn latch 3. In this way, whether at the top or the bottom of the cabinet door 2, reliable support force is provided through the cooperation of the turn latch 3 and the support member, thereby further enhancing the effect of preventing the cabinet door 2 from falling.
[0043] Embodiment 3
[0044] Based on the embodiment 2, please refer to Figure 1 The bottom of the front side of the cabinet body 1 is also provided with a correction strip 13 for correcting the cabinet body 1. When the cabinet door 2 is closed, the correction strip 13 abuts against the lower end of the cabinet body 1, thereby further preventing the cabinet door 2 from deforming and falling
[0045] Further, the correction strip 13 is also provided with a guide slope 14 for guiding the cabinet door 2. In this way, when the cabinet door 2 is closed, even if there is a certain deviation between the cabinet door 2 and the cabinet body 1, the guide slope 14 can guide the cabinet door 2 to smoothly return to the original position and tightly fit with the cabinet body 1.
[0046] In summary, the low-voltage power distribution cabinet preventing the cabinet door from falling is reasonable in hinge layout, cooperation of the locking pin and the locking block, and supporting effect of the tongue lock and the supporting piece, effectively solves the problem that the cabinet door is easy to fall in the traditional power distribution cabinet.
[0047] Obviously, the described embodiments are only part of the embodiments of the utility model, not all. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art belong to the scope of protection of the utility model.
