Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

As shown in fig. 1-6, the utility model discloses an electric box door opening structure, including box 1, chamber door 2, hinge 3, anticreep support 4, U type support 5, locking pole 6, butterfly nut 7, limiting plate 8, gusset plate 9, bolt 10, gasket 11 and packing ring 12.

The box body 1, the box door 2 and the hinge 3 are in the prior art and are conventional electrical box structures;

in the structure, the left side of a box door 2 is hinged with a box body 1 through a hinge 3; the anti-falling support 4 is fixed on the box door 2, and a groove 401 is formed in the end of the anti-falling support 4; the U-shaped bracket 5 is fixed on the box body 1; the locking rod 6 is rotatably connected with the U-shaped bracket 5, and the locking rod 6 penetrates through the groove 401; the butterfly nut 7 is connected with the locking rod 6 through threads, and the butterfly nut 7 abuts against the anti-falling bracket 4; two limiting plates 8 are fixed on the anti-falling support 4, the two limiting plates 8 are respectively arranged on the upper side and the lower side of the groove 401, the longitudinal distance between the two limiting plates 8 is smaller than the diameter of the connecting part 701 of the butterfly nut 7, and the two limiting plates 8 are parallel to the locking rod 6;

since the electrical box may need to be used in a vibration environment, the wing nut 7 is likely to be loosened, so that in order to prevent the locking rod 6 from rotating out of the groove 401 of the anti-drop bracket 4 after the wing nut 7 is loosened, the limiting plate 8 is fixed on the anti-drop bracket 4 to block the wing nut 7, and thereby prevent the locking rod 6 from being easily released to open the box door 2, specifically, as shown in fig. 6, the wing nut 7 needs to be moved to the illustrated limit position, and the locking rod 6 can be released from the groove 401 of the anti-drop bracket 4; because butterfly nut 7 is provided with two pterygoid laminas, 7 not hard up back at butterfly nut, locking pole 6 can be because of vibrations to limiting plate 8 one side removal, butterfly nut 7 is leading to when rotating because of vibrations this moment, two pterygoid laminas of butterfly nut 7 can be interfered by limiting plate 8 and blockked to slow down butterfly nut 7 to the removal velocity of locking pole 6 tail end, thereby make chamber door 2 can not open because of vibrations easily, in order to improve the security of using, when chamber door 2 need be opened, with butterfly nut 7 remove to locking pole 6 after the tail end of locking pole 6 horizontal rotation locking pole 6 again, open chamber door 2 can.

In this embodiment, as shown in fig. 3 and 4, two reinforcing plates 9 are preferably provided, two reinforcing plates 9 are respectively fixed on the upper portion and the lower portion of the anti-drop bracket 4, and the side edges of the reinforcing plates 9 are fixedly connected with the box door 2;

because chamber door 2 need often open and shut, consequently in order to avoid the long-time atress of anticreep support 4 to lead to crooked deformation, be provided with gusset plate 9 to strengthen anticreep support 4's structural strength, avoid anticreep support 4 crooked to cause chamber door 2 switch inconvenient.

In this embodiment, as a preferable mode, the reinforcing plate 9 is connected to the anti-drop bracket 4 by welding or integrally formed by a metal plate; through gusset plate 9 and the anticreep support 4 that the welding mode is connected, thickness can set up great, can improve the structural stability, and adopt the panel beating mode to set up, and panel should not be too thick, but it has the convenient advantage of shaping, specifically selects according to the user demand.

In this embodiment, as a preferable mode, the limiting plate 8 and the anti-drop bracket 4 are connected by welding or integrally formed by a metal plate; limiting plate 8 and anticreep support 4 that are connected through the welding mode, thickness can set up great, can improve the structure steadiness, and adopt the panel beating mode to set up, and panel should not be too thick, but its advantage that has the shaping facility specifically selects according to the user demand.

In this embodiment, as a preferable mode, as shown in fig. 4, a through hole 601 is provided on the locking rod 6, wherein the bolt 10 penetrates through the U-shaped bracket 5 and is locked and fixed; the locking rod 6 is sleeved on the middle section of the bolt 10 through the through hole 601;

because the locking pole 6 is through the operation of opening and shutting and the vibrations atress of long-time, it is easy to take place to buckle, and in order to avoid appearing the locking pole 6 and buckle and lead to the unable normal opening and shutting of chamber door 2, consequently locking pole 6 passes through bolt 10 and installs on U type support 5, and consequently, after the locking pole 6 is crooked, dismantles bolt 10 and can take off locking pole 6 and change or orthopedic, compares with traditional T shape locking pole, and this locking pole 6 has the advantage of easy change maintenance.

In this embodiment, as shown in fig. 3 and 4, as a preferable mode, the gasket 11 and the washer 12 are both sleeved on the locking rod 6, and the gasket 11 and the washer 12 are clamped and fixed with the anti-drop bracket 4 through the wing nut 7; the gasket 11 and the washer 12 are used for further improving the installation tightness of the butterfly nut 7 and avoiding the butterfly nut 7 from loosening too fast; due to the fact that the gasket 11 and the washer 12 are additionally arranged, if the butterfly nut 7 needs to be detached when the box door 2 is opened, the gasket 11 and the washer 12 are prone to dropping, therefore, the butterfly nut 7 of the structure is the anti-dropping butterfly nut, can move to the position shown in the figure 6 to open the box door 2, and meanwhile cannot be taken down from the locking rod 6 to prevent the gasket 11 and the washer 12 from dropping, and the butterfly nut 7 can be achieved by the existing anti-dropping butterfly nut.

The method comprises the following specific implementation steps:

when the box door 2 is closed, the locking rod 6 is rotated to move into the groove 401 of the anti-falling support 4, then the butterfly nut 7 is screwed until the butterfly nut 7 is abutted to the anti-falling support 4, even if the butterfly nut 7 is loosened during vibration, the butterfly nut 7 is blocked under the action of the limiting plate 8, so that the locking rod 6 cannot be easily disengaged, and the situation that the box door 2 is opened when the butterfly nut 7 is slightly loosened is avoided; when the door is opened, the butterfly nut 7 is moved to the tail end of the locking rod 6, and then the locking rod 6 is horizontally rotated to be separated from the anti-falling support 4, so that the door 2 can be opened.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
