Technical Field

[0001] The utility model relates to the technical field of protection of iron cabinet doors, and specifically relates to a door opening and closing limiting mechanism. Background Technique

[0002] An iron cabinet is a cabinet made of cold-rolled steel plates (commonly known as iron sheets), which is used to place documents, materials, and various archival items. Its characteristics are that it is relatively lighter in weight than a wooden cabinet, easy to move, and fireproof, moisture-proof, insect-proof, moth-proof, and corrosion-proof, so it has a wide range of applications.

[0003] At present, for the existing iron cabinets, during the rotation and opening / closing process of the hinged cabinet doors, since the opening / closing angle of the cabinet doors is relatively large (the rotation angle is between about 0° and 180°), the outer part of the cabinet door close to the door frame is prone to wear and paint peeling due to contact and friction with the edge of the door frame during long-term use. Especially for the cabinet doors in the position against the wall, they are also prone to collide with the wall and cause damage, which will easily affect the appearance and service life of the cabinet doors. Therefore, a door opening and closing limiting mechanism is proposed. Content of the Utility Model

[0005] A door opening and closing limiting mechanism includes a fixing plate. One end of the fixing plate is integrally provided with a connecting plate one perpendicular to the fixing plate. One end of the connecting plate one away from the fixing plate is integrally provided with a connecting plate two parallel to the fixing plate. One end of the connecting plate two away from the connecting plate one is integrally provided with a limiting plate perpendicular to the fixing plate. A limiting groove corresponding to the inner border of the cabinet door for limiting and clamping connection is formed among the fixing plate, the connecting plate one, the connecting plate two, and the limiting plate. The side of the front of the fixing plate away from the limiting groove is fixedly connected to the inner side of the door frame.

[0006] As a preferred technical solution of the utility model, a notch is correspondingly formed between the limiting plate and the fixing plate, and the inner border of the cabinet door is clamped into the limiting groove through the notch.

[0007] As a preferred technical solution of the utility model, fixing holes are correspondingly opened on the side of the front of the fixing plate away from the limiting groove, threaded holes corresponding to the fixing holes are opened on the inner side of the door frame, and the fixing plate is fixedly connected to the inner side of the door frame through the fixing holes, the threaded holes, and fixing bolts.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4, the present utility model provides a technical solution: a cabinet door opening and closing limiting mechanism, including a fixing plate 1. One end of the fixing plate 1 is integrally provided with a connecting plate one 2 perpendicular to the fixing plate 1. One end of the connecting plate one 2 away from the fixing plate 1 is integrally provided with a connecting plate two 3 parallel to the fixing plate 1. One end of the connecting plate two 3 away from the connecting plate one 2 is integrally provided with a limiting plate 4 perpendicular to the fixing plate 1. A limiting groove 5 corresponding to the inner frame 9 of the cabinet door 8 for limiting and clamping is formed between the fixing plate 1, the connecting plate one 2, the connecting plate two 3 and the limiting plate 4. One side of the front side of the fixing plate 1 away from the limiting groove 5 is fixedly connected to the inner side of the door frame 10. Through the limiting mechanism formed by the integral molding of the fixing plate 1, the connecting plate one 2, the connecting plate two 3, the limiting plate 4, the limiting groove 5 and the notch 6, when the cabinet door is opened and closed, the part of the inner frame on the cabinet door that rotates in the limiting groove can be limited, so that its rotation angle is not greater than 90°.

[0018] Further, as Figure 1 shown, a notch 6 is correspondingly formed between the limiting plate 4 and the fixing plate 1. The inner frame 9 of the cabinet door 8 is clamped into the limiting groove 5 through the notch 6.

[0019] Further, as Figure 1 shown, a fixing hole 7 is correspondingly opened on one side of the front side of the fixing plate 1 away from the limiting groove 5.
