In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Referring to fig. 1-6, the present invention provides a technical solution:

low-voltage switchgear's door gap sealing device, including the cabinet body 1, 1 front sides of the cabinet body are opened and are equipped with the logical groove 10 rather than inside lining up mutually, and the left side edge that leads to groove 10 is equipped with through 2 articulated cabinet doors 3 of two at least even hinges that distribute, is equipped with sealing strip 30 on the 3 left side walls of cabinet doors, leads to the upper and lower edges and the right side edge of groove 10 and installs seal assembly 4.

Sealing component 4 includes that the joint fixes fixed plate 40 on leading to groove 10, sealed 41 and reset spring 42, be close to the one side that leads to groove 10 edge on fixed plate 40 and seted up mounting groove 401, mounting groove 401's interior wide dimension and the width dimension looks adaptation that leads to groove 10, mounting groove 401 joint is in the edge that leads to groove 10, connecting groove 400 has been seted up to the one side of keeping away from logical groove 10 on fixed plate 40, sealed 41 sets up in connecting groove 400 and rather than sliding connection, sealed 41 front sides are kept away from the edge that leads to groove 10 and are offered the guide way 410 that is the slope form, guide way 410 is uprised gradually towards the direction of keeping away from cabinet door 3, be connected with a plurality of even reset spring 42 that distribute between the inboard bottom of connecting groove 400 and sealed 41, reset spring 42 one end is fixed on connecting groove.

Sealing strip 30 and sealed 41 all adopt rubber to make, when cabinet door 3 closes, cabinet door 3 left side and logical groove 10 right side wall extrusion sealing strip 30, it is sealed with left side crack, cabinet door 3 right side wall and upper and lower both sides all contact with the lower one end of guide way 410 simultaneously, and will seal up 41 to the interior pressure of spread groove 400 and move, and then outside extrusion reset spring 42, cabinet door 3 closes the back, the reset spring 42 of compressed will seal up 41 to the extrusion of cabinet door 3 direction, sealed 41 inboard and cabinet door 3 extrusion laminating of filling up 41, it is sealed with the crack of right side and upper and lower both sides. When cabinet door 3 closed, guide slot 410 can play better guide effect, prevents that cabinet door 3 from direct colliding with sealed 41 and leading to cabinet door 3 can't close.

In addition, the supporting legs 11 that four symmetries set up are closely welded in the four corners position of the cabinet body 1 bottom, support the cabinet body 1 through the supporting legs 11, improve its stability, avoid cabinet body 1 bottom direct and ground contact simultaneously, slow down its oxidation corrosion.

Furthermore, the sealing strip 30 is tightly bonded on the cabinet door 3, so that the installation and the later-stage replacement are convenient; the handle 31 is installed near the middle position of its right-hand member edge in cabinet door 3 front side, is convenient for drive cabinet door 3 through push-and-pull handle 31 and closes and open.

Secondly, the edge of the rear end of the fixing plate 40, which is far away from one side of the through groove 10, is provided with a baffle 43, the baffle 43 and the fixing plate 40 are of an integrally formed structure, and the baffle 43 is used for limiting the cabinet door 3 to prevent the cabinet door 3 from being excessively pushed and damaging the hinge 2 by pulling.

Before the door gap sealing device of the low-voltage switch cabinet is used, a worker firstly checks whether the integrity of the device is firm in connection at each position; when the cabinet is used, the cabinet door 3 is driven to be opened by pulling the handle 31, and the interior of the cabinet body 1 is installed and overhauled; after the installation overhauls the completion, promote handle 31 again and close cabinet door 3, when cabinet door 3 closes, through cabinet door 3 left side and logical groove 10 right side wall extrusion sealing strip 30, it is sealed with left side crack, cabinet door 3 right side wall and upper and lower both sides extrusion outside guide way 410 simultaneously, drive sealed 41 and remove along the spread groove 400 outside of filling up, and through sealed 41 outside extrusion reset spring 42 of filling up, reset spring 42 atress takes place elastic deformation and is compressed, after cabinet door 3 closes, compressed reset spring 42 has the trend of inside resetting, begin inside extrusion sealed 41 of filling up, sealed 41 inboard and cabinet door 3 extrusion laminating of filling up, the crack with right side and upper and lower both sides is sealed.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
