All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] Please see Figures 1-7 As shown, the handle mechanism 10 with child lock function of the present invention includes a handle body 11, a rotary clutch assembly 12 and a clutch drive assembly 13; the handle body 11 is a support body; the rotary clutch assembly 12 is rotatably mounted on the handle body 11; the clutch drive assembly 13 is detachably engaged with the rotary clutch assembly 12, and by rotating the rotary clutch assembly 12, it can achieve engagement or disengagement with the clutch drive assembly 13.

[0021] Please see Figure 3 and Figure 4 As shown, in this embodiment, the handle body 11 is shaped like a figure 7, with a limiting guide groove 111 and a first sliding groove 112 respectively passing through it. The limiting guide groove 111 limits and guides the rotary clutch assembly 12, which rotates through the handle body 11 via the first sliding groove 112. At least one engaging guide groove 113 is provided at one end of the handle body 11 near the clutch drive assembly 13, guiding the rotary clutch assembly 12. In this embodiment, two engaging guide grooves 113 are provided at opposite ends of the handle body 11. Multiple anti-slip parts 114 are also provided at the grip position of the handle body 11 to enhance the friction between the user's palm and the handle body 11. Specifically, the limiting guide groove 111 includes a first engagement groove section 1111 and a second engagement groove section 1112 arranged in parallel with each other, and a guide groove section 1113 arranged between the first engagement groove section 1111 and the second engagement groove section 1112. The first engagement groove section 1111 and the second engagement groove section 1112 respectively detachably and fixedly engage the rotary clutch assembly 12 with the first position and the second position on the handle body 11.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the rotary clutch assembly 12 includes a rotating ring 121, a reset member 122, a clutch lever 123, a transmission pin 124, a magnet 125, and at least one engaging pin 126. The rotating ring 121 is detachably engaged with the handle body 11 via a limiting guide groove 111 and can rotate relative to the handle body 11. One end of the reset member 122 is in contact with the rotating ring 121, and the other end is in contact with the handle body 11. The reset member 122 provides an elastic clamping force to the rotating ring 121, causing the rotating ring 121 to engage in the first engaging groove section 1111 or the second engaging groove section 1112. The clutch lever 123 is movably disposed through the handle body 11. One end of the transmission pin 124 is fixedly connected to the clutch lever 123, and the other end passes through the first sliding groove 112 and is connected to the rotating ring 121. The rotating ring 121 drives the clutch lever 123 to rotate in the handle body 11 through the transmission pin 124. The magnet 125 is fixedly disposed on one end of the transmission pin 124 near the clutch drive assembly 13. At least one locking pin 126 is movably disposed in the locking guide groove 113 on the handle body 11 and is in contact with the clutch lever 123. The magnet 125 is magnetically connected to at least one locking pin 126. The locking pin 126 is detachably locked to the clutch drive assembly 13, thereby driving the clutch drive assembly 13 to move and realize the unlocking operation.

[0023] Please see Figure 5 and Figure 6 As shown, specifically, a locking block 1211 is fixedly provided on the inner wall of the rotating ring 121. The locking block 1211 is movably disposed in the limiting guide groove 111. When the locking block 1211 is disposed in the first engaging groove section 1111 or the second engaging groove section 1112, the rotating ring 121 cannot rotate relative to the handle body 11. When the locking block 1211 is disposed in the guide groove section 1113, the rotating ring 121 can rotate relative to the handle body 11, thereby allowing the transmission pin 1 to pass through. 24 drives the clutch lever 123 to rotate within the handle body 11; a retaining ring 1212 is fixedly mounted on one end of the rotating ring 121, and one end of the reset member 122 is in contact with the retaining ring 1212; a second sliding groove 1213 is also provided on the inner wall of the rotating ring 121 along its axial direction, and one end of the transmission pin 124 is slidably connected in the second sliding groove 1213, thereby achieving the transmission connection between the rotating ring 121 and the transmission pin 124 through the cooperation of the transmission pin 124 and the second sliding groove 1213. Specifically, the reset member 122 is a spring, and its opposite ends are in contact with the retaining ring 1212 and the handle body 11, respectively.

[0024] Please see Figure 6As shown, specifically, a flat rotating head 1231 is provided on the end of the clutch lever 123 opposite to the clutch drive assembly 13. The engaging pin 126 is in contact with the rotating head 1231 for transmission. The rotation of the rotating head 1231 can drive the engaging pin 126 to engage with the clutch drive assembly 13. The rotating head 1231 is provided with a receiving cavity 1232. The magnet 125 is fixedly installed in the receiving cavity 1232 and can perform a magnetic attraction operation on the engaging pin 126. The magnet 123 is a strong magnet, which can magnetically attract the engaging pin 126, thereby causing the engaging pin 126 to disengage from the engaging connection with the clutch drive assembly 13. The engaging pin 126 is made of iron.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, in this embodiment, the clutch drive assembly 13 includes a clutch inner core 131 and a drive rod 132; the clutch inner core 131 is detachably engaged with two engagement pins 126; the drive rod 132 is fixedly connected to the clutch inner core 131 and moves with the movement of the clutch inner core 131. Specifically, a connecting cavity 1311 is provided on the end of the clutch core 131 opposite to the handle body 11. One end of the handle body 11 and the clutch rod 123 are respectively located in the connecting cavity 1311. Two slots 1312 are provided on the inner wall of the connecting cavity 1311. Two locking pins 126 are detachably engaged in the corresponding slots 1312. When the two locking pins 126 are engaged in the corresponding slots 1312, the handle body 11 and the clutch core 131 are connected in a transmission manner. Thus, by rotating the handle body 11, the clutch core 131 and the driving rod 132 are driven to move in sequence. The driving rod 132 drives the bolt on the lock body to move to realize the unlocking operation.

[0026] Please see Figure 8 As shown, the clutch device with child lock function of the present invention includes the handle mechanism 10 of any of the above-mentioned components.

[0027] It should be noted that the specific working process of the handle mechanism 10 with child lock function and the clutch device of the present invention is as follows: When the child lock function of the handle mechanism 10 needs to be activated, an external force acts on the rotating ring 121 to overcome the elastic force of the reset member 122, causing the locking block 1211 fixed on the rotating ring 121 to move from the first locking groove section 1111 to the guide groove section 1113. Then, through the guiding action of the guide groove section 1113 on the locking block 1211, the rotating ring 121 rotates towards the direction of the second locking groove section 1112. At the same time, the rotating ring 121 drives the flat clutch device through the transmission pin 124. When the lever 123 moves, the two locking pins 126 disengage from the corresponding locking slots 1312 under the magnetic force of the magnet 125. When the locking block 1211 moves to the connection position between the second locking slot section 1112 and the guide slot section 1113, the external force is removed. Under the restoring elastic force of the reset member 122, the rotating ring 121 engages in the second locking slot section 1112. Then, the handle body 11 is rotated. Since the two locking pins 126 disengage from the clutch drive assembly 13, the handle body 11 rotates freely and cannot drive the clutch drive assembly 13 to perform the corresponding door opening operation. When the child lock function of the handle mechanism 10 needs to be deactivated, an external force acts on the rotating ring 121 to overcome the elastic force of the reset member 122, causing the locking block 1211 fixed on the rotating ring 121 to move from the second engaging groove section 1112 to the guide groove section 1113. Then, through the guiding action of the guide groove section 1113 on the locking block 1211, the rotating ring 121 rotates towards the first engaging groove section 1111. At the same time, the rotating ring 121 drives the flat clutch rod 123 to move through the transmission pin 124. 3. The two locking pins 126 are synchronously driven to engage with the corresponding slots 1312. When the locking block 1211 moves to the connection position between the first engaging slot section 1111 and the guide slot section 1113, the external force is removed. Under the restoring elastic force of the reset member 122, the rotating ring 121 is engaged in the first engaging slot section 1111. Then the handle body 11 is rotated. Since the two locking pins 126 are engaged with the clutch drive assembly 13, the handle body 11 drives the clutch drive assembly 13 to perform the corresponding door opening operation.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
