Description
Box combination lock Technical Field The utility model relates to the technical field of box fittings, in particular to a box combined lock. Background In the field of box equipment, a locking structure of a box cover and a box is a key component for guaranteeing equipment safety, sealing performance and operation convenience. The following problems are common in the traditional box locks: The structure is complex and the operation is complicated, the partial locking piece adopts a screw fastening or multi-component combined structure, the opening and closing are completed by means of a tool, the time and the labor are consumed, and the requirement of quick opening and closing is difficult to meet. Along with the promotion of fields such as industrial equipment, commodity circulation transportation, instrument and meter to box performance requirement, market needs a box combination latch fitting that simple structure, locking are reliable, simple operation and suitability are strong urgently to solve the defect of traditional latch fitting in the aspect of efficiency, stability and commonality, satisfy the demand of modern production and service scenario. Disclosure of utility model The utility model aims to provide a box body combined lock piece so as to solve the problems in the prior art. In order to achieve the above purpose, the main technical scheme adopted by the utility model comprises the following steps: The combined lock of the box body comprises a lower fixing plate and an upper fixing plate, wherein a connecting plate is rotatably arranged in the middle of the top of the lower fixing plate through a hinge, a limiting plate is integrally formed in the top of the lower fixing plate, and a bending part is integrally formed in the top of the limiting plate through a bending transition section; The upper fixing plate color temperature top fixed mounting has the rectangular board, the spacing groove that supplies the bending part card to go into is seted up at the top of rectangular board. Preferably, the edges of the lower fixing plate and the upper fixing plate are provided with a plurality of mounting holes. Preferably, the outer wall of the connecting plate is fixedly provided with a cylinder, the cylinder is movably provided with a hand pulling piece through a pin shaft, and the hand pulling piece is provided with a kidney-shaped hole. Preferably, the outer walls of the lower fixing plate and the upper fixing plate are integrally formed with arc-shaped protruding portions. Preferably, the alignment plates are welded on the lower fixing plate and the upper fixing plate, when the bending part is clamped in the limiting groove, the two alignment plates are mutually attached, and the alignment plates are provided with through holes. The utility model has at least the following beneficial effects: The structure design of the fixing plate and the upper fixing plate is that the lower fixing plate is rotatably provided with the connecting plate through the hinge, flexible linkage is facilitated, the limiting plate and the bending part are integrally formed, the structure is stable, the shape accuracy is high, and the box cover can be locked. The rectangular plate is matched with the limit groove, the rectangular plate provides support for the limit groove, the limit groove is clamped with the bending part to lock the box cover, and the box cover is simple in structure and accurate in positioning.
