【Detailed ways】

As shown in Fig. 1 and Fig. 2, the embodiment of the handle lockset of the present utility model is used to be installed on a door panel 1, and described door panel 1 is provided with an inner side 11, an outer side 12 parallel to the inside and outside, and an Referring to the connecting surface 13 between the inner and outer surfaces 11 and 12, the handle lock can drive and assemble the dead bolt 14 assembled between the inner and outer surfaces 11 and 12 of the door panel 1 and protrude out of the connecting surface 13.

The handle lock includes a housing 3 mounted vertically and stacked on the inner surface 11 of the door panel 1, an inner handle 4 pivotally mounted on the housing 3, and an inner handle 4 that is linked and drives the deadbolt. 14 the lever 5 retracted into the connection surface 13, an outer handle mechanism 6 assembled on the outer surface 12, a locking plate 7 assembled in the housing 3, and a locking plate 7 fixed on the housing 3 A limiting clip 81 between them, and a lock button 82 whose inner end penetrates into the housing 3 and is fixed on the locking plate 7 .

As shown in Figures 2, 3, and 4, the housing 3 has a panel 31 extending up and down and parallel to the door panel 1, a surrounding wall 32 extending from the periphery of the panel 31 to the door panel 1, and a wall 32 formed in the center of the panel 31. The shaft hole 33 , a chute hole 34 located above the shaft hole 33 and roughly extending up and down, and two straight blocking pieces 35 arranged at intervals on both sides of the inner surface of the panel 31 in the longitudinal direction and extending up and down. The chute hole 34 has an unlocking end 342 away from the shaft hole 33 and a locking end 341 close to the shaft hole 33 .

The inner handle 4 has a driving section 41 pivotally mounted in the shaft hole 33 at one end, and a holding section 42 fixed at the other end of the driving section 41 and extending radially and horizontally. The driving section 41 has a square hole 411 formed on one end thereof for inserting the control rod 5 and a sleeved portion 412 with an elongated cross-section.

The control rod 5 is slightly square column-shaped, one end of which can be inserted into the square hole 411 of the driving section 41 , and the other end can drive the locking tongue 14 to retract into the connecting surface 13 . When the holding section 42 of the inner handle 4 is turned up and down, the driving section 41 can be driven to rotate together with the control rod 5 . When the control rod 5 rotates, it can drive the dead bolt 14 to retract into the connection surface 13. The detailed structure of the control rod 5 driving the dead bolt 14 is not the focus of this creation, so it will not be explained in detail.

The outer handle mechanism 6 includes an outer shell 61 which is upright and stacked on the outer surface 12 of the door panel 1 , and an outer handle 62 which can drive the lever 5 to rotate. The outer handle 62 is linked with the inner handle 4 through the control lever 5 . The detailed structure of the outer handle mechanism 6 is not the key point of the present utility model, so it is not explained much.

The locking plate 7 is slightly rectangular, and is upright and stacked between the panel 31 of the housing 3 and the inner surface 11 of the door panel 1, and its two side edges are respectively abutted against the opposite surfaces of the straight blocking pieces 35 of the housing 3, so that the locking plate 7 Lock plate 7 can only move up and down between the straight blocking pieces 35. The locking plate 7 has a round hole 71 corresponding to the shaft hole 33 of the housing 3 and having a similar diameter, and an elongated locking hole 72 extending upward from the upper edge of the round hole 71 .

The limit clip 81 is slightly inverted U-shaped and roughly surrounds the periphery of the chute hole 34 of the housing 3 , and is provided with two pointed portions 811 bent and protruding from the two sides near the center of the clip 81 .

One end of the locking button 82 is slidably inserted into the chute hole 34 of the housing 3 and fixed on the upper end of the locking plate 7 by a screw 821. The outer diameter of the locking button 82 is slightly larger than the distance between the two pointed parts 811. When the lock button 82 is moved by an external force, the tip 811 must first be stretched before passing through. After the lock button 82 passes through the interval of the tip 811, the tip 811 resets and the lock button 82 is limited. The lock button 82 is constrained by the limit clamp 81 and can be limited to the unlocking end 342 or the locking end 341 of the chute hole 34. In FIG. end 342. When the lock button 82 is pushed down by force and moves from the unlocking end 342 of the chute hole 34 to the locking end 341, it will drive the locking plate 7 to move down to the position shown in Figure 4, so that the locking hole 72 is embedded The sheathed portion 412 of the handle 4 is used to limit the rotation of the inner and outer handles 4, 62.

To sum up the above, the handle lock of the present invention uses the lock button 82 to drive the locking plate 7 to move down, so that the locking hole 72 on the locking plate 7 is nested in the sleeved part 412 of the inner handle 4, so as to prevent the inner and outer The handles 4, 62 are turned to keep the dead bolt 14 at a position protruding from the connecting surface 13, and realize the locking function with a simple structure, so it is very convenient to use, so it is indeed very practical and progressive.
