Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically to a handle lock with a reverse-mounted concealed switch. Background Technology

[0002] Door and window handles are widely used components on doors and windows. The installation of handles with doors and windows makes them easy to open and close. Existing door and window handles usually only require turning the handle to open the window. While convenient, they also pose certain safety hazards. For example, families with children need to keep a close eye on their children to prevent them from opening doors and windows carelessly while playing, which could lead to accidents such as falling or getting stuck. Therefore, it is necessary to strengthen the safety of door and window handles.

[0003] In the existing door and window handle structures with child locks, some handles unlock the child lock by reversing the handle before opening, while others use a pressing or toggle switch to unlock the child lock. However, both types of handle locks have certain drawbacks. The process of reversing the handle before opening affects the smoothness of opening the door. If the handle is opened directly without reversing the handle, it is easy to damage the transmission components. The handle switch for unlocking the child lock is easily exposed in a position that children can touch, which may lead to accidental touch and unauthorized unlocking, and thus cannot play a stable protective role.

[0004] Furthermore, regarding the locking function of the lever lock, when the existing lever is applied to blinds, the blinds may be affected by external forces or the weight of the glass sash during use. When the window sash is affected by external forces or the weight of multiple glass sashes causes the window sash to close or droop unexpectedly, the existing old-style blind lever will cause the lever to close back. Therefore, the lever lock also needs to have a stable function that can keep the lever in the open state. Utility Model Content

Detailed Implementation

[0026] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0027] A handle lock with a reverse-mounted concealed switch includes a handle lock body, the handle lock body includes a handle body 1 and a handle base 2, the handle base 2 is provided with a transmission component 3, one end of the handle body 1 is connected to the transmission component 3 and the handle body 1 is provided with a safety lock component 4 connected to the handle base 2.

[0028] In the technical solution of the handle lock body of this utility model, the handle body 1 is hinged to the handle base 2. Rotating the handle body 1 controls the movement of the transmission component 3 in the handle base 2, thereby realizing the opening or closing of the door or window. The handle body 1 and the handle base 2 are locked by a safety lock component 4. In the locked state, the handle body 1 cannot be rotated, which plays a safety protection role.

[0029] In the technical solution of the handle body 1 of this utility model, a first mounting groove 11 is provided on the inner side of the handle body 1, and the safety lock assembly 4 is disposed in the first mounting groove 11 for locking the handle body 1 and the handle base 2 to prevent children from accidentally opening it;

[0030] The safety lock assembly 4 includes a positioning clip 41, a pressing member 42, and a first spring member 424. One end of the pressing member 42 is provided with a connecting end 421 that is inserted into the handle base 2. The first spring member 424 is disposed between the bottom of the first mounting groove 11 and the pressing member 42.

[0031] Specifically, a first mounting groove 11 is provided on the inner end face of the handle body 1 facing the handle base 2. The positioning clip 41 is fixed in the groove position of the first mounting groove 11 by screwing, which plays a limiting role for the pressing member 42. One end of the pressing member 42 is provided with a connecting end 421 that is inserted into the handle base 2 to realize the limiting function, and a pressing part 422 is provided at the other end. The pressing part 422 extends through the positioning clip 41 toward the handle base 2. When the handle body 1 is held, the extension and retraction of the connecting end 421 are controlled by pressing the pressing part 422.

[0032] Furthermore, the back of the pressing member 42 is provided with a spring groove 423, and the first spring member 424 is provided in the spring groove 423. One end of the first spring member 424 abuts against the bottom of the first mounting groove 11, and the other end abuts against the bottom of the spring groove 423. Under the action of the first spring member 424, the connecting end 421 remains in an extended limit state. When opening, pressing the pressing part 422 squeezes the first spring member 424, and after controlling the retraction of the connecting end 421, releasing the pressing part 422 pushes the connecting end 421 to spring back and automatically reset, preventing the user from forgetting to reset the child lock after entering or leaving.

[0033] Furthermore, in the above solution, the end face of the positioning clip 41 that fits with the pressing member 42 is provided with an arc-shaped mounting groove 411, and the positioning clip 41 is provided with a through hole 412 near the end of the arc-shaped mounting groove 411, which corresponds to the position of the connecting end 421. The arc-shaped mounting groove 411 guides the operation of the pressing member 42, and the connecting end 421 of the pressing member 42 extends outward along the through hole 412.

[0034] In the technical solution of the handle base 2 of this utility model, the handle base 2 is provided with the transmission component 3. The top end of the transmission component 3 extends outward along the top of the handle base 2 and is connected and fixed to the handle body 1. The top end face of the handle base 2 is provided with a plurality of connecting grooves 23 that are adapted to the shape of the connecting end 421 around the outward extension of the transmission component 3. The connecting end 421 on the handle body 1 is inserted into the connecting groove 23 so that the handle body 1 cannot rotate, thereby achieving the locking function.

[0035] The handle base 2 is provided with a second mounting groove 21 with an opening facing downward. The transmission component 3 is provided in the second mounting groove 21. The opening of the second mounting groove 21 is provided with a cover plate 5. The bottom of the second mounting groove 21 is provided with a mounting hole 22 communicating with the outside. The top end of the transmission component 3 extends along the mounting hole 22 and is connected and fixed to the handle body 1. Several connecting grooves 23 are provided around the outer edge of the mounting hole 22.

[0036] It should be noted that, under normal circumstances, in order to enable the lever lock body to have a self-locking and anti-accidental opening function, it is only necessary to set the connecting groove 23 at the connecting end 421 when it is in the locked state. This will enable the lever lock to have a self-locking function and prevent children from accidentally opening it. However, considering the universality of the lever lock, and considering the problem that existing old-style louver levers may cause the lever to close back when the window sash is subjected to external force interference or the weight of multiple glass sashes causes the window sash to close or droop unexpectedly, the lever lock can be fixed by setting multiple connecting grooves 23 in a circular array. When the lever is rotated to multiple angles, releasing the pressing part 42 can fix the lever lock. This effectively solves the problem that the lever will close back when the window sash is subjected to external force interference or the weight of multiple glass sashes causes the window sash to close or droop unexpectedly, thus increasing the universality of the lever lock.

[0037] Furthermore, in the above solution, a screw fixing structure 7 is provided between the cover plate 5 and the handle base 2, which passes through the cover plate 5 towards the handle base 2, and a screw mounting structure 8 passes through the handle base 2 towards the cover plate 5. A decorative buckle plate 9 is provided on the handle base 2 corresponding to the screw mounting structure 8.

[0038] The screw fixing structure 7 fixes the cover plate 5 to the handle base 2. The screw mounting structure 8 is used to install the handle base 2 on the door leaf. The screw is screwed on one side of the outer facade of the handle base 2 to fix the handle base 2 to the door leaf. The decorative buckle plate 9 serves to cover it.

[0039] In the technical solution of the transmission component 3 of this utility model, the transmission component 3 includes a shift fork 31 and a transmission component 32. The transmission component 32 includes a rotating gear 321 and a transmission rod 322 extending upward out of the mounting hole 22. The shift fork 31 includes a sliding end 311 extending into the second mounting groove 21 and a shift fork end 312 extending outward through the cover plate 5.

[0040] The sliding end 311 slides along the length direction of the second mounting groove 21 and is provided with a rack 313 adapted to the rotating gear 321. The screw at the axial position of the rotating gear 321 is connected and fixed to the handle body 1.

[0041] Furthermore, in the above scheme, the rotating gear 321 and the transmission rod 322 are integrally formed. The outer surface of the transmission rod 322 is provided with a plurality of grooves 323, and a positioning structure 6 is sleeved at the corresponding position of the grooves 323. The positioning structure 6 includes a positioning member 61, a second spring member 62 and a positioning ball 63. The positioning member 61 is provided with at least one groove 64 with an opening facing the rotating gear 321. The second spring member 62 is disposed in the groove 64, and the positioning ball 63 is sandwiched between the second spring member 62 and the grooves 323.

[0042] The positioning structure 6 serves a positioning function. When the handle body 1 rotates, the positioning ball 63 slides along the outer surface of the transmission rod 322. When the positioning ball 63 slides to the position of the groove 323, the second spring 62 abuts the positioning ball 63 in the groove 323, helping the user to judge the rotation position of the stroke. The user can perceive a clear rotation stroke.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
