The door frame has a good pivoting effect, not only can automatically close the door, but also has the simple and fast performance of assembly and disassembly. [Prior Art] The conventional metal cabinet is connected to the door panel. It is most commonly used as a simple hinge. The side end of one of the two bodies is crimped into a hollow pivot tube, and the pivot axes of the left and right bodies are combined. The overlapping 'from-pivot through' is welded to the left door frame and the sill plate by the left and right sheets respectively - a simple hinge is constructed, and the hinge is used to open and close the door panel; Any automatic returning Wei must be closed by the user's force, and it is easy to forget the door due to human negligence, causing damage to the seesaw or injury to the human body. For this reason, the age is concerned with safety and energy. For the convenience of the user, the hinges now have some structures with automatic returning, which can eliminate the disadvantages of the slaves closing the door. As shown in the attached file, ^^ The structure of the structure is improved, the heart is sucking, the automatic closing pattern and the patent are applied. The range content can be obtained by the door structure just having the function of automatically closing the door, but the component connecting piece 5. - Upper 15, limit seat 20, drive rod 3. The fixing ring 4❶, the assembly and disassembly of the components are added and added, and the surface is improved a lot. M296904 In view of the above shortcomings, the main purpose of the present invention is to solve the problems in the assembly and use of the connecting components of the conventional door panel and the door frame. In order to solve the above problems, the present invention provides a cabinet automatic return door closing device, comprising: a positioning member, which is disposed on the door frame, and the outer side is a locking plate, and the inner edge of the plate extends laterally at an upper and lower side to form an L. a plate body, and the end of the plate is wound into a hollow pivot tube, and the two pivot pipes are formed into a hollow portion, and a corresponding hole is formed in the upper portion of the locking plate corresponding to the hollow portion, and a missing groove is formed in the hollow portion; The rotating member is fixed on the door panel, and the inner end is crimped to form a hollow long frame tube, and the long pivot tube can be axially aligned with the two pivotal tubes of the positioning member; the fastening member is fixed on the door panel. Located on the outer side of the rotating member and corresponding to the positioning member, the fastener is an obtuse angle <shaped plate body' is longitudinally folded and provided with a downwardly-shaped buckle groove; the torsion spring' sleeve is placed at the hollow portion of the positioning member. The end-setting hook buckle can be used to fasten the buttonhole of the clamping member, and the other end is extended into a rod body, which can be buckled on the buckle groove of the fastener; the pivot shaft is hinged to the positioning member and the rotating member. The hollow tube of the tube, the long pivot tube and the torsion elastic is pivoted; thereby forming a cabinet to automatically return Gate means. The cabinet provides automatic returning and closing device for the cabinet, and uses the pivot to fix the positioning member, the rotating member and the twisting spring, and the torsion spring-end buckles the positioning member, and the other end buckles the fastener. After the spring is released by external force, the torsional elastic force is released, so that the π plate can automatically return to the M296904 axial rotation. Compared with the door frame, the effect of the _ door is simple and simple, and the performance of the "turning (four), fast performance is observed. By. [Embodiment] As shown in the figure, the creation provides a body-to-fine (four) door device, including a clamping member (1), a rotating member (2), a fastener (3), a torsion spring (4), and a pivot (7). The composition is: wherein: the clamping member (1) is a metal sheet-body molding, and the outer side is a locking plate (11) having a plurality of locking holes (12) 'the locking plate (1)) The lateral extension extends such that the clamping member (1) is an L-shaped plate body, and its end is crimped into a hollow pivot tube (13) (14). The two pivot tubes (13) (14) form a hollow portion (10). A locking hole (16) and a missing slot (17) connected to the hollow portion (15) are respectively arranged at a position corresponding to the hollow portion (10); the rotating member (3) is a metal plate body Formed, in a pure angle <shaped plate body, the inner side of the crucible is wound into a hollow long pivot tube (21), and the long pivot tube (21) can be used as the upper and lower shafts of the two pivoting tubes (13) (H) of the positioning member (1) The fastener (3) is a metal plate-formed body with an obtuse angle <type plate body, and a longitudinally folded corner (31) is provided with an opening downward groove (32); the torsion spring (4) 'is - a hollow elastic body with a hook (41) at one end. The buckle hole (16) of the clamp member (1) is fastened, and the other end is extended into a rod body (42), which can be buckled on the buckle groove (32) of the fastener member (3); the pivot shaft (5) is a shaft rod The upper end has a cap portion (5)), and the pivot shaft can be based on the two pivot pipes (13) (14) of the positioning member (1), the long pivot pipe (21) of the rotating member (2), and the torsion spring (4) M296904 The hollow is pierced and pivoted. The working body is automatically returned to the door closing device, and the rotating member (7) and the fastener (the bar of the coffee plus torsion spring (4) can be placed in the missing groove (17) of the positioning member (1), and then The inner end of the rotating member (2) that has been fixed to the door panel (6) has a long pivot tube (21) that is engaged with the positioning member (1) and the tow tube (13) (14) and the torsion spring (4) The shaft (5) is pivotally connected, and then the rod (42) of the torsion spring (4) is pivotally buckled into the buckle groove (32) of the fastener, and so on, the user can Simple and quick completion of the assembly of the door panel (6), to achieve the shaft lock) (7) corresponding to the locking hole (5) at the appropriate position of the door frame (7), please refer to the first figure to the fourth_show, when the creation is assembled The locking member (9) of the locking member (the locking hole (12) of the door frame (7) is screwed and locked by the screw (7)), so that the positioning member (1) is fixed to the door frame (7) 'the hollow portion of the positioning member (1) (15) The torque spring (4) is placed inside, and the buckle (4) of the torsion spring (4) is fastened to the button hole (10) of the positioning member (1), and the rotation is automatically returned to the door frame (7). Closed, it is easier to repeat the disassembly and assembly. However, the above description is only for the preferred embodiment of the present invention, and the equivalent structure and device variation of the present invention and the scope of the patent application are still within the scope of the patent of the present invention.
