DETAILED DESCRIPTION

[0021] The utility model will be further described below in combination with examples.

[0022] The following examples are used to illustrate the present application, but cannot be used to limit the protection scope of the present application. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements of the method of the present application under the concept of the present application all belong to the protection scope of the present application.

[0023] Please refer to Figs. 1-3 The utility model provides a kind of adjustable hidden hinge, including first connecting component 1, fixed component 2 and second connecting component 3, first connecting component 1 is connected with second connecting component 3 by fixed component 2;

[0024] Second connecting component 3 includes second connecting plate 301, third mounting hole 302, fourth mounting hole 303 and fifth mounting hole 304 are set in second connecting plate 301, third mounting hole 302 and fourth mounting hole 303 are all sawtooth hole, first connecting component 1 includes first connecting plate 101, first connecting plate 101 is set with first mounting hole 102 and second mounting hole 103, fixed component 2 includes bolt 201, bolt 201 is inserted in second mounting hole 103 and fifth mounting hole 304, bolt 201 is externally threaded with nut 202, nut 202 is overlapped with second connecting plate 301, first connecting plate 101 and second connecting plate 301 are overlapped on one side, by being provided with bolt 201 and nut 202, when bolt 201 passes through second mounting hole 103 and fifth mounting hole 304, and nut 202 is threaded on the outside of bolt 201, bolt 201 and nut 202 are connected together by mutual cooperation of first connecting plate 101 and second connecting plate 301;

[0025] The position of second mounting hole 103 corresponds to the position of fifth mounting hole 304, third mounting hole 302 is arranged between fourth mounting hole 303 and fifth mounting hole 304, first mounting hole 102, second mounting hole 103 and fifth mounting hole 304 are all set as circular through hole, by being provided with first mounting hole 102, first connecting plate 101 can be connected with other objects by bolt 201 passing through first connecting hole.

[0026] The hinge is connected in the form of through, can adapt to the working condition of greater stress, meanwhile, the connecting plate and the groove steel connection place adopt square continuous sawtooth hole design, can cooperate square neck bolt 201 and connect in the form of through, can prevent the security risk of slipping.
