Abstract

The utility model relates to a hinge, in particular to a concave double-door invisible hinge, which solves the problems that because the prior concave double-door hinge is visible, the appearance quality of an operation board is influenced in actual use; the durability is bad; and the hinge position is difficult to sort out. The concave double-door invisible hinge comprises an upper hinge and a lower hinge; the upper hinge is provided with a connecting piece; for convenient installation and dismantlement, the connecting piece is formed by an U-shaped board and a L-shaped board; one end of the U-shaped board is fixed with the upper hinge and one end of the L-shaped board is connected with a door; and the other end of the U-shaped board is movably connected with the other end of the L-shaped board by a bolt. The utility model is additionally provided with the connecting piece based on the prior upper hinge structure, so that, after the door is installed, the hinge can not be seen on the surface; a plurality of problems of the prior visible hinge can be avoided effectively; the integrated quality of the operation board appearance is improved greatly; the hinge position is easy to sort out; moreover, the utility model has the advantages of simple improved structure, low cost, good use effect, extensive application range and good popularity value.

Description

Depressed double door blind hinge

Technical field

The utility model relates to a kind of hinge, is specially a kind of depressed double door blind hinge.

Background technology

Usually, depressed double door hinges such as existing locomotive cabinet door as shown in Figure 1, be divided into upper and lower hinge, hinge welds with door and door edge respectively up and down, the postwelding polishing, and hinge is exposed after installing, be back-flap hinge, in actual use, there is following shortcoming: (1) door hinge projection, reduce console overall appearance quality; (2) weld seam is short and small, and weldquality is difficult to guarantee, though and weld seam can improve outward appearance through polishing, always influence the console presentation quality greatly because of welding position polishing difficulty; (3) hinge is with door, the doorframe gap is little, and door grinds off the coating on door, the doorframe when rotating easily, also can cause a generation wave transformation simultaneously, influences the console presentation quality; (4) use of back-flap hinge also influences the wiping of cabinet, is difficult to clean out at hinge position.

Summary of the invention

The utility model is a back-flap hinge in order to solve existing depressed double door hinge, influences the console presentation quality in actual use, is not durable, problem such as hinge position difficulty cleaning, and a kind of depressed double door blind hinge is provided.

The utility model is to adopt following technical scheme to realize: depressed double door blind hinge, comprise upper hinge and following hinge, innovative point of the present utility model is to be provided with on the upper hinge connector, for easy installation and removal, a U-shaped plate and an end that described connector is fixed by an end and upper hinge constitute with a fixing L shaped plate, the other end of U-shaped plate and the other end of L shaped plate flexibly connect by bolt, during concrete the installation, it is inboard that following hinge is installed in an edge, like this, to go up, following hinge and weld seam are hidden in the cabinet or behind the door, constitute blind hinge, have avoided a lot of defectives of existing back-flap hinge.Described U-shaped plate will take into full account blind hinge with L shaped plate design and concern with door is connected back and door edge with an edge position, and each revolving part and door edge are interfered.

Compared with prior art, the utility model increases connector on the structure of original upper hinge, after making that door is installed, can't see hinge at external surface, the various problems of effectively having avoided existing back-flap hinge to exist, improved the total quality of console outward appearance greatly, easy to clean, and improve simple in structure, cost is lower, result of use is better, the scope of application is wider, has certain popularization value.
