[0058] A limiting boss 317 is provided in the middle of the top surface of the base body 31. The height of the limiting boss 317 is adapted to the thickness of the base protective case 32.

[0059] A second spring installation position is provided in the locking block setting groove 313. A second spring groove is provided on the bottom surface of the locking block 314. One end of the second spring is sleeved on the second spring installation position, and the other end is arranged in the second spring groove.

[0060] The side surface of the locking block 314 close to the limiting boss 317 is an inwardly concave arc surface. The shape and size of the locking block 314 setting groove are adapted to the shape and size of the locking block 314.

[0061] A guiding convex portion 3141 is provided on the side surface of the locking block 314 away from the arc surface. The guiding convex portion 3141 is arranged at the lower part of the locking block 314. A guiding groove 3131 is provided in the locking block setting groove 313. The guiding groove 3131 is arranged along the depth direction of the locking block setting groove 313. A limiting portion is provided at the upper end of the guiding groove 3131. The guiding convex portion 3141 is slidably arranged in the guiding groove, and the limiting portion is adapted to the guiding convex portion.

[0062] One end of the square shaft 4 is arranged in the square shaft hole 312, and the other end is arranged in the square shaft insertion hole 217 and is connected to the lock body.

[0063] The working process of the present invention is as follows:

[0064] Install the lock core in the lock body cavity surrounded by the handle housing, sleeved the baffle on the lock body, and anchor or weld the baffle to the handle housing. Fix the base body on the door or window by screws, install the locking block and the first spring in the locking block setting groove, install the base protection shell on the base body, insert one end of the square shaft into the square shaft hole, install the handle on the square shaft, make the locking block penetrate the through hole on the baffle and be arranged in the locking block setting groove, and make the lock core rotating shaft abut against the locking block.

[0065] When the key is inserted into the lock core through the first keyhole, as the key is inserted, the end of the key passes through the second keyhole, causing the upper reed and the lower reed to retract into the upper reed groove and the lower reed groove respectively. At this time, the upper reed is arranged above the limit convex ring. When the key is inserted to the bottom of the second keyhole, the teeth on the side of the key are arranged in the locking groove, and the key and the lock core are integrated as a whole. The key can drive the lock core to rotate or move up and down along the lock core groove.

[0066] Press the key downwards. The key drives the lock core rotating shaft to move downwards in the lock core groove, causing the upper reed to be arranged below the limit convex ring as the lock core rotating shaft moves downwards. Rotate the key to drive the lock core rotating shaft to rotate, and the reed rotates in the reed groove along with the lock core rotating shaft in the reed rotating groove. When the key is pulled out, under the limiting action of the limit convex ring, the upper reed presses the locking block downwards, causing it to disengage from the locking block sliding groove. The handle is unlocked from the base, and the handle can rotate on the base and drive the square shaft to rotate to open the window.

[0067] When it is necessary to re-lock the handle and the base, insert the key into the lock core. The reed retracts into the reed groove, and the limit convex ring loses the limiting effect on the upper reed. Under the action of the first spring of the locking block, it moves upwards, re-inserts into the locking block sliding groove, and pushes the lock core rotating shaft upwards. When the key is pulled out, the upper reed is back in the reed limiting groove, and the handle and the base are locked through the locking block.

[0068] Compared with the prior art, the lock-equipped window handle provided by the present invention has the following advantages:

[0069] (1) Split-type installation. The lock-equipped window handle includes a handle, a lock core arranged in the handle, a base and a square shaft. The components of the lock-equipped window handle can be assembled first and then the handle and the base can be assembled. The installation is simple and convenient, and there is no need to separately open a base and a lock hole on the door or window.

[0070] (2) The base includes a base body and a protection shell. The base body is installed on the door or window by screws, and the protection shell is detachably installed on the base body through a buckle and a buckle groove. The base is convenient to disassemble, and at the same time, it effectively avoids the loosening, falling off or corrosion of the screws of the base body, which affects the connection firmness between the window handle and the door or window.

[0071] (3) The handle is of a split type. The handle includes two handle shells and a baffle which are snap-fitted. Each component of the handle can be separately molded, reducing the production difficulty and cost of the handle, the handle shell and the baffle;

[0072] (4) The lock core includes a lock body, a lock core rotating shaft and a reed. A limiting convex ring is provided in the lock core groove on the lock body. The reed is telescopically arranged in the reed groove in the lock core rotating shaft. The locking of the lock core is realized through the cooperation of the reed and the limiting convex ring. The lock core structure is simple and reliable, and has good safety;

[0073] (5) The locking block is provided with an arc surface, and a guiding convex part is provided on the side surface of the locking block. The shape and size of the locking block setting groove are adapted to the locking block. A guiding groove is provided in the locking block, and a limiting part is provided at the upper end of the guiding groove. Through the arc surface and the guiding groove, the connection firmness of the locking block in the locking block setting groove is improved, and at the same time, the stability of the locking block moving in the locking block setting groove is improved, avoiding the locking block being separated from the locking block setting instantaneously under the influence of the elastic force of the second spring, and improving the reliability of the lock core structure.

[0074] The present invention is not limited to the above best implementation mode. Anyone should know that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention.
