Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, a planar pressing latch includes a base 10, two rocker mechanisms including two hooks 60, two latches 70 and two torsion springs 80, a pressing mechanism including a pressing push rod 30, a compression spring 40 and a clamp spring 50, a fixing screw 100, a lock cylinder 20 and a lock tongue 90.

Referring to fig. 2, a hook 60 of a planar pressing buckle has a first chamfer 601 at the upper part, a pin mounting hole 602 at the side, a torsion spring mounting groove 603 inside, and a hook tip 604 at the bottom.

Referring to fig. 3, a pressing push rod 30 of a planar pressing latch has a pressure spring mounting post 301 in the middle, two square guide rails 303 at two ends, an inner chamfer inclined plane 304 at each inner side of the square guide rails 303, and a clamp spring fixing groove 302 formed on the pressure spring mounting post 301.

Referring to fig. 4, a base 10 of a planar pressing buckle has two bolt fixing holes 101 formed on a side surface thereof, a lock cylinder mounting hole 102 formed on a top surface thereof, and a pressing push rod mounting hole 103.

Referring to fig. 1, in a planar pressing latch, two torsion springs 80 are respectively installed in torsion spring installation grooves 603 of two hooks 60, two bolts 70 are respectively installed in bolt installation holes 602, and two torsion springs 80 are respectively sleeved on the two bolts 70 to form a rocker mechanism. The pressure spring 40 is sleeved on the pressure spring mounting column 301, and the clamp spring 50 is mounted in the clamp spring fixing groove 302 to form a pressing mechanism. The two rocker mechanisms are installed in the base 10 in the direction of the hook tip 604 towards the two ends of the base 10, the two pins 70 are respectively fixed in the two pin fixing holes 101, the two rocker mechanisms rotate by taking the pins 70 as axes, and after the pressing mechanism is installed in the pressing push rod installation hole 102, the two inner chamfer inclined planes 304 are respectively closely attached to the two outer chamfer inclined planes 601.

When the push rod 30 is pressed, the compression spring 40 contracts, the rectangular guide rail 303 moves downwards, the inner chamfer inclined planes 304 respectively extrude the outer chamfer inclined planes 601, the hook 60 rotates towards the inner side of the base 10 by taking the bolt 70 as an axis, and the torsion springs 70 respectively generate torsion towards the outer side of the base 10.

When the pressing push rod 30 is loosened, the pressure spring 40 rebounds under the self elasticity to push the pressing push rod 30 to move upwards, the extrusion force of the inner chamfer inclined plane 304 on the outer chamfer inclined plane 601 disappears, and the torsion spring 70 drives the hook 60 to rotate around the bolt 70 as the axial direction outside the base 10 under the action of the torsion force.

Referring to fig. 5, a lock cylinder 20 of a plane press lock catch is installed in a lock cylinder installation hole 103, a latch 90 is installed on the lock cylinder 20 through a fixing screw 100, since there is no interference between the latch and a lock cylinder side hook 60, when a key is inserted into the lock cylinder 20 and rotated, the latch 90 can smoothly rotate around the center of the lock cylinder 20, when a person rotates the lock cylinder 20 with the key to rotate the latch 90 to a position below a rectangular guide rail 303 on one side of the lock cylinder 20, and when a push rod 30 is pressed, the rectangular guide rail 303 on one side of the lock cylinder 20 is blocked by the latch 90 to prevent the rectangular guide rail 303 from moving downwards, so that the push rod 30 cannot push the hook 60 to rotate, the hook 60 is still hooked on a box 120, and the panel 110 in fig. 2 cannot be opened.

When the latch 90 is rotated to a position not under the rectangular guide 303 on the key cylinder 20 side and the push rod 30 is pushed, the two hooks 60 are rotated to the inner side of the base 10 by the downward pressing force of the pressing mechanism due to no blocking of the latch 90, the two hooks 60 are rotated to the hook holes 1201 of the case 120, and when the panel 110 of the case 120 in fig. 2 is opened, the hooks 60 are smoothly removed from the hook holes 1201. Because two hooks 60 replace a lock tongue 90 to realize the lock catch function of the box body and the panel, the stress surface of the panel is increased, thereby improving the mechanical performance of the lock catch, being not easy to damage, and being beneficial to the planarization installation of electric products because a planar pressing mechanism replaces a traditional raised rocker handle.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
