A knob is further provided on the locking block, and a sliding groove for the knob to pass through is provided on the surface of the mounting base. The knob slides along the axis of the sliding groove to drive the locking block to move away from the rotational connection hole against the elastic force of the elastic member, so that the clamping post is far away from the clamping groove to form an unlocking posture.
[0006] The knob is provided with a snap structure, and the inner wall of the sliding groove is provided with two pits that cooperate with the snap structure, and the snap structure is selectively snapped into one of the two pits to indicate that the locking block is in a locked posture or an unlocking posture.
[0007] When the locking block is in the locked posture, the elastic member is exposed in the sliding groove.
[0008] The sliding groove is located on the top surface of the mounting base.
[0009] An installation post extends downward at the installation hole on the back of the mounting base, and a guiding groove is provided on the locking block, and the installation post passes through the guiding groove.
[0010] The mounting base protrudes with a sleeve, and the inner hole of the sleeve forms the rotating connection hole. A sleeve cavity matching with the sleeve is arranged on the back surface of the handle. A rotating shaft is arranged in the sleeve cavity. The handle sleeved the sleeve through the sleeve cavity, and the rotating shaft penetrates into the sleeve to realize the rotational connection between the handle and the mounting base.
[0011] The rotating shaft is inserted into the sleeve cavity in a split structure; the rotating shaft penetrates into the sleeve from the back of the mounting base and passes through the sleeve and is inserted into a limiting hole in the sleeve cavity for limiting connection, and a ring platform is arranged at the bottom of the rotating shaft to abut against the bottom of the sleeve.
[0012] A decorative cover is further installed and covered on the top surface of the mounting base. An elastic washer is sleeved in the sleeve cavity, and the bottom surface of the elastic washer abuts against the top surface of the decorative cover.

[0022] Figure 6 This is a cross-sectional view of the present utility model. Detailed implementation mode
[0023] Refer to Figures 1 to 6 A self-locking window door handle, comprising a handle 2 and a mounting base 1. A rotating shaft 5 is provided on the handle 2 and penetrates into the mounting base 1 to achieve rotational connection. The mounting base 1 is provided with mounting holes 11 for installation and fixation and a rotational connection hole 12 for the rotating shaft 5 to pass through.
[0024] A locking block 6 that can slide towards the rotational connection hole 12 is mounted on the back of the mounting base 1. A through groove 14 is provided on the hole wall of the rotational connection hole 12. A clamping post 61 is arranged at one end of the locking block 6 facing the rotational connection hole 12, and the other end abuts against an elastic member 71 so that the locking block 6 is kept in the locked posture of always moving towards the rotational connection hole 12 under the elastic force. A clamping groove 51 is provided on the peripheral wall of the rotating shaft 5. The clamping post 61 passes through the through groove 14 and enters the rotational connection hole 12 to be inserted into the clamping groove 51 to limit the rotation of the rotating shaft 5, that is, to prevent the handle from rotating to open the door or window; a knob 62 is further provided on the locking block 6, and a sliding groove 13 for the knob 62 to pass through is provided on the surface of the mounting base 1. The knob 62 slides along the axis of the sliding groove 13 to drive the locking block 6 to move away from the rotational connection hole 12 against the elastic force of the elastic member 71, so that the clamping post 61 is separated from the clamping groove 51 to form an unlocking posture, and the handle can be unlocked by manually operating the locking block 6.
[0025] Through the above structure, when turning the handle to open the window, it is necessary to first operate the locking block 6 to unlock, so that children cannot easily open the door or window through the handle. Moreover, the locking block 6 always maintains the locked posture through the elastic member 71. When the handle rotates to make the clamping groove 51 on the rotating shaft 5 cooperate with the locking block 6, the locking block 6 will be pushed by the elastic force of the elastic member 71 to automatically make the clamping post 61 snap into the clamping groove 51 to limit the rotation of the handle, realizing the automatic locking of the handle and avoiding the situation that the handle is not locked due to misoperation or forgetting by the user.
[0026] As a preferred embodiment of the present utility model, a snap structure 64 is provided on the dial button 62. The inner wall of the chute 13 is provided with two pits 15 that cooperate with the snap structure 64. The snap structure 64 selectively snaps into one of the two pits 15 to indicate that the locking block 6 is in the locked or unlocked position. When the snap structure 64 snaps into the pit 15, there will be an obvious "click" sound, indicating that the operation of the locking block 6 reaches the position of the locked or unlocked position, thus giving the user a clear indication of successful operation. Specifically, the snap structures 64 are symmetrically arranged on both sides of the dial button 62, and the pits 15 are also symmetrically arranged on the opposite side walls of the chute 13. The symmetrical cooperation of the snap structure 64 and the pits 15 is conducive to the stable sliding of the dial button 62. The chute 13 is preferably arranged on the top surface of the mounting base 1, that is, the dial button 62 is arranged to pass through the top surface of the mounting base 1, which is convenient for the user to observe and operate. Further, when the locking block 6 is in the locked position, the elastic member 71 is exposed in the chute 13. When the user no longer needs to use the self-locking function, the elastic member 71 can be hooked out from the chute 13 by a tool. At this time, the locking block 6 loses the elastic force that pushes it towards the rotation connection hole 12 and loses the self-locking function; and after losing the force applied by the elastic member 71, the cooperation between the snap structure 64 and the pit 15 can maintain the locked and unlocked positions of the locking block 6.
[0027] Preferably, an installation post 16 extends downward from the installation hole 11 on the back of the mounting base 1. The locking block 6 is provided with a guiding groove 63. The installation post 16 passes through the guiding groove 63. When the locking block 6 moves, it cooperates with the installation post 16 through the guiding groove 63, so that the locking block 6 can be guided to move along the track of the guiding groove 63, making the movement of the locking block 6 smoother.
[0028] As a preferred embodiment, the mounting base 1 protrudes with a sleeve 3. The inner hole of the sleeve 3 forms the rotation connection hole 12. The back surface of the handle 2 is provided with a sleeve cavity 4 that cooperates with the sleeve 3. The rotation shaft 5 is arranged in the sleeve cavity 4. The handle 2 sleevs the sleeve 3 through the sleeve cavity 4, and the rotation shaft 5 passes through the sleeve 3 to realize the rotational connection between the handle 2 and the mounting base 1, reducing the installation height between the handle and the mounting base 1. On this basis, the installation relationship between the sleeve 3 and the rotation shaft 5 is reasonably utilized for further structural arrangement to enrich the functions of the handle, such as:
[0029] The rotating shaft 5 is inserted into the sleeve cavity 4 in a split structure. The rotating shaft 5 penetrates into the sleeve 3 from the back of the mounting base 1 and passes through the sleeve 3 and is inserted into the limiting hole 41 in the sleeve cavity 4 for limiting connection. A ring platform 52 is provided at the bottom of the rotating shaft 5 and abuts against the bottom of the sleeve 3. That is, the assembly of the handle and the mounting base 1 is realized while connecting the rotating shaft 5 with the sleeve cavity 4. Preferably, a set screw 42 is inserted horizontally into the sleeve cavity 4. The set screw 42 passes through the side wall of the sleeve cavity 4 and the rotating shaft 5 to fix the rotating shaft 5, so that the rotating shaft 5 serves as the core rotating component of the handle 2 and the mounting base 1, and is also the connection main body for their relative assembly.
[0030] The structure of the handle 2 of the present utility model can be modified according to different window lock methods. For example, when adopting a transmission handle scheme in which a transmission shaft 8 is in transmission connection with the inner lock body of the window door (not shown in the figure), a transmission hole for inserting the transmission shaft 8 is provided at the bottom of the rotating shaft 5. One end of the transmission shaft 8 is inserted into the transmission hole, and the other end is connected to the lock body inside the window door. By rotating the handle 2, the lock body inside the window door can be driven to work to lock or unlock the window door. A ball mechanism 9 is horizontally installed on the transmission shaft 8. An elastic telescopic ball 91 is provided at the end of the ball mechanism 9. A groove 31 into which the ball 91 is snapped is provided on the inner wall of the sleeve 3. There are two or more grooves 31 and they are arranged circumferentially along the inner wall of the sleeve 3. The limiting points formed by each groove 31 define the rotation angle stop position of the handle 2. The locking state of the window door lock body can be represented by the cooperation of the ball 91 and the groove 31 to form a stop position, so that the user can clearly know that the handle 2 rotates in place and realizes unlocking or locking. When in the unlocking or locking state, a certain torque is brought to the handle 2 to prevent the handle from rotating easily due to factors such as gravity or slight touch and losing the current state, which is more beneficial for the user's next operation.
[0031] As a preferred solution, a decorative cover 10 is further installed and covered on the top surface of the mounting base 1. An elastic washer 72 is sleeved in the sleeve cavity 4, and the bottom surface of the elastic washer 72 abuts against the top surface of the decorative cover 10 to press the decorative cover 10 against the top surface of the mounting base 1 by elastic force. When it is necessary to operate the button 62 to unlock, the edge of the decorative cover 10 can be held to lift it against the elastic force of the elastic washer 72, and then the button 62 is exposed by rotation to perform the operation. By adding a rotatable and openable decorative cover 10 to cover the button 62, it is more difficult for children to find, thereby further increasing the safety guarantee. A shielding cover 17 covering the locking block 6 and the elastic member 71 is further installed on the back of the mounting base 1. The shielding cover 17 can limit the installation of the locking block 6 and the elastic member 71 on the mounting base 1, keep the stable installation and operation of the locking block 6 and the elastic member 71, and the shielding cover 17 is fixed on the mounting base 1 by spin welding and hot melting of 4 welding posts.
