[0006] A two-way three-dimensional lock block is characterized in that it includes a lock seat with a groove in the lock seat, a lock tongue rotatably connected in the lock seat, a hook arm is provided at the end of the lock tongue, and a positioning point is connected to the end of the hook arm; a sliding groove is provided on the outer side of the lock tongue, a sliding block is matched in the sliding groove, and the sliding block is connected to the transmission bar.

[0007] Furthermore, the lock seat consists of two parts.

[0008] Furthermore, the lock tongue includes a rotating shaft, which is connected to the lock seat; a protruding block is also arranged on one end of the rotating shaft.

[0009] Furthermore, the sliding grooves are arranged on the lower surface and the side surface of the rotating shaft.

[0010] Furthermore, in the lock tongue, a chamfer is provided on the outer side of the hook arm, and a positioning groove is provided in the lock seat corresponding to the position of the chamfer.

[0011] Furthermore, the sliding block is provided with an arc-shaped protrusion, which fits in the sliding groove.

[0012] Furthermore, a sliding channel is formed between the lower portion of the lock tongue and the lock seat, an extension plate extends from the lock block, and the extension plate is installed in the sliding channel.

[0013] Furthermore, the bidirectional three-dimensional locking block is installed on the door fan, a locking groove is formed in the frame, and a positioning groove is opened in the locking groove; when locked, the hook arm is matched in the locking groove, and the positioning groove is matched with the positioning point.

[0014] Beneficial effects of the utility model:

[0015] The utility model provides a bidirectional three-dimensional lock block, which can achieve locking in both the horizontal and vertical directions. When locked, the hook arm cooperates with the lock groove, and the positioning groove cooperates with the positioning point, which has good sealing performance and safe and reliable effects. In addition, when the bidirectional three-dimensional lock block provided by the utility model is damaged, only the lock block needs to be replaced. Compared with the prior art in which the window is dismantled and the entire transmission rod and lock are replaced, maintenance is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further explained below through specific implementation methods.

[0027] Example 1

[0028] Referring to the accompanying drawings, the utility model provides a two-way three-dimensional lock block, characterized in that it includes a lock seat 1, a groove is provided in the lock seat 1, a lock tongue 2 is rotatably connected in the lock seat 1, a hook arm 2.1 is provided at the end of the lock tongue, and a positioning point 2.2 is connected to the end of the hook arm 2.1; a sliding groove 2.3 is provided on the outer side of the lock tongue 2, a sliding block 3 is matched in the sliding groove 2.3, and the sliding block 3 is connected to the transmission bar;

[0029] The lock tongue 2 includes a rotating shaft 2.4, which is connected to the lock seat 1; the rotating shaft 2.4 is also provided with a protruding block 2.5 at one end of the rotating shaft 2.4. When the lock tongue is locked, the protruding block 2.5 is opposite to the sliding block 3 to prevent the lock tongue 2 from rotating and leaving the locked position.

[0030] The sliding groove 2.3 is arranged on the lower surface and the side surface of the rotating shaft, and the sliding block 3 is provided with an arc-shaped protrusion 3.1, which fits in the sliding groove 2.3, so that the sliding block 3 drives the locking tongue 2 to rotate when sliding.

[0031] A sliding channel is formed between the lower part of the lock tongue 2 and the lock seat 1 , and an extension plate extends from the lock block 3 , and the extension plate is installed in the sliding channel to limit the movement of the lock block 3 .
