As shown in fig. 1-12, the utility model discloses a vertical hinged door lock, which comprises a handle 1, a lock surface 2, an inner lock switch 3, a square tube 4, an iron sheet 5, an elastic sheet 6 and a locking nut 7; the handle 1 is provided with a handle head 10 and a handle 11 which are inserted into the locking surface 2; the handle head 10 is provided with a flat position 12, and the lock surface 2 is provided with a handle mounting hole 20 for inserting the handle head 10 and a spring sheet groove 21 for mounting a spring sheet; the handle head 10 is inserted into the handle mounting hole 20, the elastic sheet 6 is mounted in the elastic sheet groove 21, the flat position 12 of the handle head 10 is clamped by the elastic sheet 6, and the handle 1 can be reset by the elastic sheet 6 after being rotated; the tail end of the handle head 10 is fixed with the locking nut 7 to prevent the handle head 10 from withdrawing; the internal locking switch 3 is installed on the handle 11, the internal locking switch 3 is connected with the iron sheet 5, and the square tube 4 is inserted on the handle head 10 and rotates along with the rotation of the handle 1.

The handle head 10 is provided with a through hole 13, one end of the iron sheet 5 is connected with the inner lock switch 3, the outer lock switch 14 can be driven to rotate, and meanwhile, the inner lock switch can be driven to rotate by rotating the outer lock switch, so that locking and loosening are realized; so that unlocking can be realized by rotating the handle. The through-hole 13 of the handle head 10 is a square hole, so the square pipe 4 is inserted into the square hole to be fixed, the square pipe can be driven to rotate by rotating the handle, and then the lock tongue is driven by the square pipe, so that unlocking is realized.

After the structure is adopted, the square tube is inserted into the handle head, so that unlocking can be realized by rotating the handle; through setting up handle mounting hole and shell fragment groove at the locking face, so the handle head can pass the handle mounting hole to through the one end of lock nut locking handle head, the shell fragment groove can install the shell fragment of a slice or a plurality of pieces in addition, cliies the flat position of handle head through the shell fragment, so keeps handle and locking face parallel, ensures the handle installation back, the depth of parallelism of handle. And the handle head is locked by the locking nut, so that the handle is not easy to loosen, and compared with the situation that the handle head is locked by a clamp spring in a transmission mode, the handle head is firmer and not easy to loosen up and down. Because the elastic sheet is adopted to reset the rotating handle head, the groove is dug on the lock surface and the handle head is cut into flat positions only for processing the lock surface, so that the production precision requirement is low, the production difficulty is reduced, and the production cost is reduced.

Preferably, the locking nut 7 is fixed with the handle head 10 by a set screw, so that the locking nut is fixed without any protruding screw head, and the surface is more beautiful.

Preferably, the elastic sheet 6 is a strip-shaped elastic sheet, so that the elastic sheet is jacked up by the handle head, so that the elastic sheet protrudes outwards and deforms to promote the handle to reset; and because the shell fragment is rectangular shape, easy to assemble and process more.

Preferably, a nut gasket 8 is further installed between the locking nut 7 and the locking surface 2, so that the handle is more tightly installed through the nut gasket, and the locking nut is more wear-resistant.

Preferably, the handle gasket 9 is arranged on the butt surface of the lock surface 2 and the handle 1, so that the handle is in contact with the lock surface more wear-resistant.

Preferably, the nut gasket 8 and the handle gasket 9 are plastic gaskets, so that the friction sound is smaller and the handle is more wear-resistant when the handle rotates.

Specifically, the locking face 2 is further provided with a caulking groove 22 for the locking nut and a locking face mounting hole 23 for mounting and fixing the locking face, so that the locking nut can rotate in the caulking groove, and the locking face can be fixed on the door frame or the window frame through the locking face mounting hole.

Preferably, the spring plate groove 21 is provided with a convex space 21a for the spring plate to protrude outwards, so that the spring plate can be pushed out by the handle head and can be arched outwards.
