Description

Car handrail case presses unblock structure Technical Field The utility model relates to the technical field of injection molds, in particular to a pressing and unlocking structure of an automobile armrest box. Background The automobile armrest box comprises a box body and a box cover, wherein the box cover is hinged with the box body through a hinge, a locking mechanism is generally arranged between the box body and the box cover and is mainly used for locking the box cover, so that the box cover is buckled on the box body, the locking mechanism generally comprises a movable lock tongue and a button, a lock hole is formed in the box cover, the lock tongue of the locking mechanism is buckled in the lock hole of the box cover, thereby locking the box cover, the button is needed to be pressed when the box cover is unlocked, and the button drives the lock tongue to rotate, so that the lock tongue is separated from the lock hole, and unlocking of the box cover is realized. The double-door armrest box is also called a double-open armrest box and comprises a box body and two box covers, wherein the two box covers are respectively hinged to the left side and the right side of the box body through hinge parts, and a locking mechanism needs to lock and unlock the two box covers simultaneously, so that the locking mechanism needs to ensure that the two box covers can be locked and unlocked synchronously. The prior locking mechanism, also called as a pressing unlocking structure, generally comprises a handrail locking mechanism, a handrail opening mechanism and a locking mechanism, wherein the handrail locking mechanism comprises a lock tongue rotatably arranged on a handrail box and used for locking a handrail cover, the lock tongue is rotated forward and backward on the handrail box to lock and open the handrail cover, the handrail opening mechanism comprises an opening button fixing support and an opening button which is connected with the opening button fixing support in a sliding manner, and a lock tongue push rod which extends towards the lock tongue direction and drives the lock tongue to rotate is fixedly arranged at the bottom of the opening button.
