SUMMERY OF THE UTILITY MODEL

The utility model aims at having the above-mentioned problem to current technique, provided a lock structure of containing box, the utility model provides a technical problem provide the lock structure of high strength.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a door lock structure of containing box, containing box include the box, one side of box is equipped with the chamber door, the chamber door includes door frame and two door plants, two the door plant rotates respectively and connects the both sides at the door frame, its characterized in that, door lock structure includes two locking slide blocks that are rectangular shape, the spout has been seted up along length direction on the locking slide block, two the upper end and the lower extreme of door plant are leaned on closely relatively and all are equipped with the slide rail, locking slide block passes through the cooperation sliding connection of spout and slide rail on the door plant, and locking slide block can be on two door plants when two door plants close the back and forth movement between the slide rail that corresponds, the anticreep groove has been seted up on the slide rail, be close to notch department on the cell wall of spout and be equipped with the anticreep lug, the anticreep lug is located the anticreep groove.

The two door plates are connected to the door frame in a split door mode, and the locking sliding block connects and fixes the two sliding rails when being connected to the two sliding rails at the same time, so that the two door plates cannot be opened oppositely, namely the two door plates are closed and locked when the locking sliding block is connected to the sliding rails on the two door plates at the same time; when the two locking sliding blocks are integrally positioned on the sliding rail of one door plate, the two door plates can be freely opened; the locking sliding blocks positioned on the upper side and the lower side of the door plate can fix the upper side and the lower side of the two door plates, so that the two door plates after being locked are integrated, and the anti-extrusion capacity is improved; the anticreep lug can avoid locking the slider and break away from the slide rail, further promotes the joint strength between locking slider and the slide rail, locks slider non-deformable simultaneously, and the structural strength who also is this lock structure is higher, guarantees that the door plant is not opened by the extrusion.

In the door lock structure of the storage box, two sections of sliding rails at the upper end or the lower end of the two door panels are in the same group, and the length of at least one section of sliding rail in the two sections of sliding rails is greater than or equal to that of the locking sliding block. The structure ensures that the locking slide block can be at least integrally positioned on one section of the slide rail. Preferably, the length of the slide rail at the other end is half of the length of the locking slider, that is, when two door panels are locked, half of the locking slider is located on one door panel, and the other half is located on the other door panel.

In the door lock structure of the storage box, the outer side of the locking slider is provided with the anti-slip bump. The anti-slip bump can conveniently push the locking slide block.

In the door lock structure of the storage box, the upper side and the lower side of the door frame are both provided with locking holes, the locking holes are aligned with the longer slide rails, the locking holes comprise an opening section and a locking section, the locking slide block is provided with a convex slide fastener part, when the locking slide block is simultaneously connected to the slide rails on the two door plates, the slide fastener part is aligned and fixed with the locking section, and when the locking slide block is integrally positioned on the longer slide rails, the slide fastener part is aligned with the opening section and can be separated from the opening section. When the two door plates are closed and locked, the sliding buckle part on the locking slide block is matched with the locking section of the locking hole, so that the locking slide block is fixedly connected with the door frame at the moment, namely the locking slide block cannot move outwards, and therefore the stability of locking the two door plates for closing and locking can be further improved, and the two door plates are prevented from being extruded and opened; when the door plate needs to be opened, the locking sliding block slides to the sliding rail on one of the door plates, at the moment, the sliding buckle part slides to the position corresponding to the opening section, and when the door plate is opened, the sliding buckle part can be separated from the opening section, so that the door plate can be freely opened.

In the door lock structure of the storage box, the sliding buckle part is of a T shape and comprises a connecting part connected with the locking sliding block and a buckle part located at the end part of the connecting part, the connecting part can penetrate through the locking hole, the width of the opening section is greater than that of the locking section, the width of the buckle part is smaller than that of the opening section and greater than that of the locking section, and the buckle part abuts against the back face of the door frame corresponding to the locking section when the sliding buckle part is aligned with the locking section. When the two door plates are closed and locked, the buckling parts correspond to the locking sections with smaller widths and cannot penetrate through the locking sections to realize locking; when the two door panels are opened, the buckling parts correspond to the opening sections with larger width, and can penetrate through the opening sections to realize free opening of the door panels.

In the above-mentioned door lock structure of containing box, the width of locking section reduces from the one end that is close to the section of opening to the other end gradually, connecting portion can be connected with the other end tight fit of locking section. When the locking slide block closes and locks the two door plates, the locking slide block is positioned through the tight fit of the connecting part and the locking section.

Compared with the prior art, this containing box's lock structure has structural strength higher, guarantees that the door plant is not by the advantage that the extrusion was opened.
