DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-6 As shown, a combined low-voltage switch cabinet includes a cabinet body 1, a plurality of installation drawers 11 are evenly arranged on the front side of the cabinet body 1, and a control mechanism is arranged between the installation drawers 11 and the cabinet body 1;

[0026] The control mechanism includes a bottom carrier plate 2, a limit slider 23 and an on-off assembly. A suspension 21 is provided in the cabinet body 1. The suspension 21 is provided with a guide rail 22 matching the installation drawer 11. The limit slider 23 and the on-off assembly are both two in number and are arranged in groups on the left and right sides of the bottom carrier plate 2 in a one-to-one correspondence. The limit slider 23 is slidably arranged in the guide rail 22. The on-off assembly is arranged on the bottom carrier plate 2 and connected and matched with the limit slider 23. The installation drawer 11 is arranged on the upper end of the bottom carrier plate 2.

[0027] The switch assembly includes an insert and a pull member. The insert is arranged between the limit slider 23 and the bottom carrier plate 2. The pull member is embedded in the bottom carrier plate 2 and connected and matched with the insert.

[0028] When using the device, the electrical components are installed in the installation drawers 11, wherein several installation drawers 11 can partition the electrical components of different systems to improve the planning control and later maintenance of the electrical components;

[0029] When it is necessary to inspect and maintain the electrical components in the corresponding installation drawer 11, the installation drawer 11 can be pulled out to expose the electrical components in the installation drawer 11, and the corresponding components can be conveniently inspected and maintained. Furthermore, due to the high operating height of the installation drawer 11 during actual inspection, maintenance, inspection or subsequent replacement and installation, the operation height is high and the operation is inconvenient. At this time, according to actual needs, the connection between the engaging part and the limiting slider 23 can be cancelled through the pulling piece in the on-off assembly, so that the bottom carrier plate 2 can rotate relative to the limiting slider 23, that is, the installation drawer 11 can be flipped, thereby reducing and exposing the installation space of the installation drawer 11, so that it is more convenient for maintenance personnel to operate. In order to improve the pulling-out stability of the installation drawer 11, the limiting slider 23 is a damping sliding connection between the guide rail 22, which can avoid the sliding between the installation drawer 11 and the guide rail 22 being too loose and causing component collision.

[0030] The fitting comprises a cylinder 3, a spline body 31 and a connecting shaft 32. One end of the cylinder 3 is fixedly connected to the bottom carrier plate 2, and the other end of the cylinder 3 is rotatably connected to the limit slider 23. The connecting shaft 32 is slidably connected to the bottom carrier plate 2 and matched with the pulling member. The spline body 31 is fixedly and concentrically connected to the other end of the connecting shaft 32, and the limit slider 23 is provided with a spline groove 33 matching the spline body 31.

[0031] The pulling member includes a sliding plug 4, a spring 41, a cable 42 and a handle 43. The bottom carrier plate 2 is provided with a step cavity 44 concentric with the cylinder 3. The sliding plug 4 is slidably arranged in the sliding plug 4 through a guide rib. The cable 42 is connected to the rear end of the sliding plug 4 and slides out of the front end of the bottom carrier plate 2. The handle 43 is slidably arranged at the front end of the bottom carrier plate 2 and is connected to the cable 42. The spring 41 is sleeved on the cable 42 and is located in the step cavity 44.

[0032] When adjusting the operating angle of the installed drawer 11, after the installed drawer 11 is completely pulled out of the cabinet body 1, both hands can hold the handles 43 on both sides of the front end of the bottom carrier plate 2 and pull it outwards. At this time, the handles 43 slide to pull the slide plug 4 through the cable 42. At the same time, the spring 41 is compressed, and the slide plug 4 moves to the side away from the limit slider 23, which will drive the spline body 31 to disengage from the spline groove 33 of the limit slider 23 through the connecting shaft 32. At this time, the bottom carrier plate 2 and the limit slider 23 are only connected in rotation by the cylinder 3. On the one hand, the connection of the cylinder 3 can ensure that the bottom carrier plate 2 and the limit slider 23 have a real-time connection relationship. On the other hand, the cylinder 3 is fixedly connected to the bottom carrier plate 2 and is rotatably connected to the limit slider 23. To meet the adjustment of the flipping angle of the bottom carrier plate 2, when the flipping adjustment is completed, the handle 43 can be slowly released, and the spline body 31 is again close to the limit slider 23 through the reset effect of the spring 41, so that the spline body 31 is embedded in the spline groove 33 of the limit slider 23 to limit the bottom carrier plate 2. Further, when the spline body 31 is not completely connected and engaged with the spline groove 33, it can be known by observing the reset state of the handle 43 that the drawer 11 can be slightly flipped up and down manually at this time, so that the spline body 31 is completely engaged for limiting. In this way, the angle state of the drawer 11 can be more flexibly adjusted according to the actual height of the installed drawer 11, so as to be more suitable for maintenance operation needs;

[0033] Furthermore, since the horizontal height of the installed drawers 11 on the lower side of the cabinet 1 is relatively low, in order to reduce equipment costs, based on the average height of a person, the installed drawers 11 on the lower side of the cabinet 1 below 1-1.5 meters may not be provided with a control mechanism, and only the installed drawers 11 may be sufficient. In this way, the adjustment function can be provided only for the installed drawers 11 with a higher horizontal height to reduce the cost of the equipment.

[0034] The front end of the bottom carrier plate 2 is also provided with an auxiliary handle 45 located on the side of the handle 43; this makes it easier to apply force and control the installation of the drawer 11 when pulling the handle 43.

[0035] A door lock is also provided between the installation drawer 11 and the cabinet body 1, and the door lock is one of a latch-type door lock or a bolt-type door lock; in this way, the installation drawer 11 can be limited and protected to prevent unauthorized personnel from opening the installation drawer 11 at will.

[0036] The left and right sides of the cabinet 1 are both connected with overhaul door panels 5 by bolts; when necessary, the left and right sides of the cabinet 1 can be directly opened to observe and maintain the internal electrical components.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
