[0002] In the door and window lock system, the handle is a device installed on the door and window that has the function of fastening after opening and closing. The handle cooperates with the transmission lock box, and the processing force is transmitted to the transmission lock box, thereby driving the transmission lock box to control the movement of the hardware in the door and window lock system to realize the opening and closing of the door and window. The handle is mostly made of aluminum alloy, copper, stainless steel, organic glass, plastic and other materials, with various forms and sizes. The existing handle usually includes a main body and a rotating shaft, wherein the rotating shaft is usually polygonal and needs to be installed with the lock box. When installing this lock box, holes need to be punched on the profile to connect the handle with the transmission box and lock box. The installation steps are relatively cumbersome. In families with children, children can also Inadvertently opening doors and windows may cause the handles to be opened by mistake, which poses a safety hazard. With the continuous promotion and application of handles, users are also making certain technical improvements and upgrades to these problems, thereby gradually and effectively solving the above problems. For example, the "Handle for a Lock Box that Can Be Installed Without Drilling" disclosed in the Chinese patent "CN202221341644.3" adds a self-locking device that uses a sliding pin to control the opening and self-locking states of the handle, thereby improving the safety of users when using it. However, with this design method, the self-locking mechanism can be easily noticed by people. As long as the user observes carefully, he can freely control the self-locking mechanism to be unlocked or locked, and cannot achieve a good concealment effect. Utility Model Content

[0004] By adopting the above technical solution, the user controls the self-locking part to rotate the locking block away from the cam, so that the locking block is separated from the cam. At this time, the handle body is in the unlocked state, and the user can freely control the handle body to unlock; the user controls the self-locking part to rotate the locking block toward the cam until the locking block contacts the cam, so that the locking block and the cam form a limit. At this time, the handle body is in the locked state, and the user cannot unlock it freely. The original sliding latch self-locking device is replaced with a self-locking device in which the cam and the locking block are linked, making the appearance more concealed and not easy to be discovered. While improving the concealment effect of the self-locking mechanism, the aesthetics of the milling-free handle safety lock is improved.

[0010] When the handle is unlocked, the user controls the self-locking member to rotate the lock block in the direction away from the cam. When the handle is unlocked, the user controls the self-locking member to rotate the lock block in the direction away from the cam. When the handle is unlocked, the user controls the self-locking member to rotate the lock block in the direction close to the cam. When the handle is unlocked, the user controls the self-locking member to rotate the lock block in the direction close to the cam. When the handle is unlocked, the user controls the self-locking member to rotate the lock block in the direction close to the cam. When the handle is unlocked, the user controls the self-locking member to rotate the lock block in the direction close to the cam. When the handle is unlocked, the user controls the self-locking member to rotate the lock block in the direction close to the cam. When the handle is unlocked, the user controls the self-locking member to rotate The corresponding contact of the force card slot is replaced by the self-locking part contacting the corresponding contact of the first elastic card slot, and then the elastic component pops out, and the self-locking part forms a relatively specified connection to keep the handle body in a locked state; through this setting, the user controls the self-locking part to switch the handle body to a locked state or an unlocked state, and maintains stability, thereby improving the practicality of the milling-free handle safety lock; when the elastic component leads to elastic exhaustion or damage as the use time increases, by setting the elastic component installation slot, the user can remove the face cover, and then freely replace the elastic component, thereby reducing the maintenance and repair costs of the milling-free handle safety lock.

The original sliding latch self-locking device is replaced with a self-locking device that is linked to the cam 20 and the locking block 410, making the appearance more concealed and not easy to be discovered. While improving the concealment effect of the self-locking mechanism, it also improves the aesthetics of the milling-free handle safety lock.

[0031] The mounting panel includes an outer mounting panel 42 and an inner mounting panel 43. The outer mounting panel 42 is arranged between the inner mounting panel 43 and the handle body 1. The mounting groove 10 is provided with a limiting groove 11. A limiting member 430 is extended from the lower end of the outer mounting panel 43 to enable the outer mounting panel 42 to be fixedly connected to the mounting groove 10.

[0032] The installation panel is divided into an outer installation panel 42 and an inner installation panel 43, which improves the user's production efficiency; when the user installs the outer installation panel 42, a limiting groove 11 is opened in the installation groove 10, and a limiting member 420 is set at the lower end of the outer installation panel 42. The user only needs to align the limiting member 420 with the limiting groove 11 and insert the outer installation panel 42 into the installation groove 10 to complete the installation of the outer installation panel 42, thereby reducing the difficulty of installing the outer installation panel 42.

[0033] An auxiliary mounting block 421 is extended from the upper end of the outer mounting panel 42, and a guide groove 422 is opened at one end of the auxiliary mounting block 421.

By setting an auxiliary installation block 421 extending from the upper end of the outer installation panel 42, and an auxiliary installation edge 30 extending from the lower end of the face cover 3, the user only needs to contact the auxiliary installation edge 30 with the auxiliary installation block 421 during installation to complete the alignment of the central axis of the face cover 3 with the central axis of the installation panel, thereby completing the installation and further reducing the difficulty of installation; a guide groove 422 is provided at one end of the auxiliary installation block 421, and when the user controls the self-locking part 41 to rotate, the locking block 410 rotates accordingly, prompting the locking block 410 to contact and guide the auxiliary installation block 421, so that the self-locking part 41 is more stable when rotating.

[0035] An elastic member installation groove 31 is provided at the lower end of the face cover 3, and one end of the elastic member installation groove 31 is open and arranged on the outer peripheral surface of the face cover 3. An elastic component is provided in the elastic member installation groove 31, and a first elastic card groove 411 and a second elastic card groove 412 are provided on the inner peripheral surface of the self-locking member 41; when the self-locking member 41 controls the handle body 1 to be in a locked state, the elastic component contacts the first elastic card groove 411; when the self-locking member 41 controls the handle body 1 to be in an unlocked state, the elastic component contacts the second elastic card groove 412.

[0036] The user controls the self-locking member 41 to rotate the locking block 410 in the direction away from the cam 20. During the rotation, the elastic component is subjected to the inward pressure of the self-locking member 41, and the elastic component generates elastic deformation and thus contracts inward. The self-locking member 41 contacts the corresponding first elastic slot 411 and is replaced by the self-locking member 41 contacts the corresponding second elastic slot 412. Then the elastic component pops out, and the self-locking member 41 forms a relatively fixed connection, keeping the handle body 1 in the unlocked state; the user controls the self-locking member 41 to rotate the locking block 410 in the direction close to the cam 20, and during the rotation, the elastic component is subjected to the inward pressure of the self-locking member 41, and the elastic component generates elastic deformation and thus contracts inward. The self-locking member 41 The self-locking part 41 that contacts correspondingly with the second elastic slot 412 is replaced with the self-locking part 41 that contacts correspondingly with the first elastic slot 411, and then the elastic component pops out, and the self-locking part 41 forms a relatively specified connection, keeping the handle body 1 in a locked state; through this setting, the user controls the self-locking part 41 to switch the handle body 1 to a locked state or an unlocked state, and maintains stability, thereby improving the practicality of the milling-free handle safety lock; when the elastic component leads to elastic exhaustion or damage as the use time increases, by setting the elastic component installation slot 31, the user can remove the face cover 3, and then freely replace the elastic component, thereby reducing the maintenance and repair costs of the milling-free handle safety lock.

[0037] The elastic component includes an elastic member 50 and a resisting member 51 . One end of the elastic member 50 contacts the elastic member installation groove 31 , and the other end of the elastic member 50 is in contact with the resisting member 51 , prompting the resisting member 51 to be arranged close to the outer peripheral surface of the cover 3 .

[0038] By setting the elastic component as an elastic member 50 and a resistance member 51, the user only needs to pre-place the resistance member 51 in the elastic member installation groove 31, and then install the elastic member 50 in the elastic member installation groove 31, thereby reducing the difficulty of installing the milling-free handle safety lock.

[0039] The auxiliary installation edge 30 is provided with a locking block limiting groove 32 , which controls the rotation angle of the self-locking member 41 to force the elastic component to contact the first elastic clamping groove 411 or the second elastic clamping groove 412 .

[0040] When the user rotates the self-locking part 41 to control the handle body 1 to a locked state or an unlocked state, it is inevitable that the user will use too much force, resulting in the user rotating the self-locking part 41 too much, which greatly affects the user experience. The auxiliary installation edge 30 is provided with a locking block limit groove 32 to control the rotation angle of the self-locking part 41. When the user rotates the self-locking part 41 to control the handle body 1 to a locked state or an unlocked state, the rotation can be stopped immediately, thereby improving the convenience of users in using the milling-free handle safety lock and improving the user experience.

The upper end of the installation panel is provided with a latching tooth 423, and the lower end of the cam is provided with a gear 42. The user only needs to connect the output shaft 2 with the latching tooth 423 through the gear 42 to cover the face cover 3 and the self-locking part 41 and install them on the installation panel, which further reduces the difficulty of installing the milling-free handle safety lock.

[0043] A gasket 5 is provided between the mounting panel and the face cover 3. A rotation column clearance groove 33 is provided at the lower end of the face cover 3. The gasket 5 is sleeved on the output shaft 2. The lower end of the gasket 5 contacts the cam 20. An auxiliary rotation column 50 is extended from the upper end of the gasket 5. The auxiliary rotation column 50 is inserted into the rotation column clearance groove 33.

[0044] The user installs the milling-free handle safety lock on the door, and the handle body 1 is in the unlocked state. The user rotates the handle body 1 to drive the output shaft 2 to rotate to perform the unlocking work. During the unlocking process, the output shaft 2 and the surface cover 3 will inevitably have slight collisions and frictions, thereby affecting the service life of the milling-free handle safety lock. A gasket 5 is provided between the installation panel and the surface cover 3, and an auxiliary rotating column 50 is extended from the upper end of the gasket 5. This arrangement avoids direct collisions and frictions between the output shaft 2 and the surface cover 3, thereby improving the service life of the milling-free handle safety lock.
