The utility model omits the description of known components and known technologies, so as to avoid unnecessarily limiting the utility model.

As shown in Figures 1 and 2, a lock structure for the upper cover of a case includes a case 1, an upper cover 2 and a lock mechanism, the upper end of the front side of the case 1 is provided with a lock inner groove 3, and the upper The lower end of the front side of the cover 2 is provided with a lock outer slot 4; Tightly, so that the upper cover 2 is locked on the chassis 1.

The locking mechanism is installed on the upper end of the front side of the chassis 1 , and the locking mechanism includes a locking button 5 , a locking fixing plate 6 , a locking spring 7 and a locking protrusion 8 . The lock fixing plate 6 adopts an “L” shaped elongated structure, the lock fixing plate 6 adopts an elastic steel sheet, and the lower end of the lock fixing plate 6 is connected with the inner side of the cabinet 1 . The inner side of the upper end of the front side of the cabinet 1 is provided with an upper limit plate 9, and the upper limit plate 9 is located on the inner side of the upper end of the lock fixing plate 6, and the upper limit plate 9 is used to prevent the lock during the lock operation. The fixing plate 6 moves excessively to the inside of the cabinet 1 . The front side of the chassis 1 is provided with a locking pressing groove 10, and the locking pressing groove 10 is located below the inner groove 3 of the lock; the locking button 5 is movable inside and outside and installed on the locking In the pressing groove 10 , the inner end of the locking button 5 is connected to the locking fixing plate 6 , and the outer end of the locking button 5 protrudes out of the locking pressing groove 10 . The outer end surface of the lock button 5 adopts a circular structure, and the outer end surface is provided with finger pressure grooves, and the finger pressure grooves are set corresponding to the fingers of the human body, which can improve people's comfort when pressing the lock button 5 .
