DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to describe in detail the specific embodiments, structures, features and effects according to the present utility model as follows.

[0017] Referring to the above-mentioned drawings, a door handle for preventing accidental opening by children provided by the present utility model includes a front panel and a rear panel 1. The front panel is configured with a fingerprint unlocking head. The rear panel 1 includes a housing 2 and a cover plate detachably connected by a plurality of screws, and a handle 3 is rotatably provided on the rear panel 1. The feature is that: a linkage disk 4 is provided on the handle 3 inside the rear panel 1, a card slot 5 facing the handle 3 is provided on the linkage disk 4, a driving block 6 that can be inserted into the card slot 5 is movably penetrated through the front of the housing 2, and an anti-lock knob 7 is rotatably provided on the rear panel 1, and the anti-lock knob 7 is provided with a dial linked to the lock.

[0018] Referring to Figure 2As shown in the figure, it is a schematic diagram of the internal structure of the first embodiment of the driving block 6 and the card slot 5 in the present utility model. The linkage disk 4 is provided with a column 8, and the card slot 5 is arranged on the column 8. The outer shell 2 is provided with a first through hole 9 for the driving block 6 to pass through. The inner wall of the first through hole 9 is provided with a first annular platform 10. The left part of the driving block 6 is provided with a first step 11 that can abut against the first annular platform 10. A linkage block 12 that can enter the first through hole 9 is movably arranged in the card slot 5. A first spring 13 is arranged between the linkage block 12 and the bottom of the card slot 5. When the first step 11 abuts against the first annular platform 10, a part of the linkage block 12 is located in the card slot 5 and another part is located in the first through hole 9.

[0019] In this embodiment, in the normal state, the linkage block 12 and the driving block 6 tend to move outwards under the elastic force of the first spring 13, so that the first step 11 abuts against the first annular platform 10. A part of the linkage block 12 is located in the card slot 5 and another part is located in the first through hole 9. The linkage disk 4 and the handle 3 cannot rotate. When opening the door, hold the handle 3 with your hand. At this time, the index finger just aligns with the driving block 6. Press the driving block 6 to drive the linkage block 12 to move inwards. When the linkage block 12 disengages from the first through hole 9, the handle 3 and the linkage disk 4 can be rotated to open the door. When the driving block 6 is over-pressed and inserted into the card slot 5, the handle 3 and the linkage disk 4 cannot be rotated either, effectively preventing children from accidentally opening the door and being safer.

[0020] Refer to Figure 2 As shown in the figure, a travel groove 14 is arranged at the bottom of the card slot 5. The linkage block 12 is provided with an insertion rod 15 inserted into the travel groove 14. When the insertion rod 15 abuts against the bottom of the travel groove 14, the linkage block 12 is located in the card slot 5. In this embodiment, when the driving block 6 is pressed to the bottom, the insertion rod 15 abuts against the bottom of the travel groove 14, so that the linkage block 12 is located in the card slot 5. At this time, the handle 3 and the linkage disk 4 can be rotated to open the door.

[0021] Refer to Figure 3 As shown in the figure, it is a schematic diagram of the internal structure of the second embodiment of the driving block 6 and the card slot 5 in the present utility model. The linkage disk 4 is provided with a column 8, and the card slot 5 is arranged on the column 8. The outer shell 2 is provided with a second through hole 16 for the driving block 6 to pass through. The inner wall of the second through hole 16 is provided with a second annular platform 17. The left part of the driving block 6 is provided with a second step 18 aligned with the second annular platform 17. A second spring 19 is arranged between the second step 18 and the second annular platform 17. When the driving block 6 abuts against the bottom of the card slot 5, a part of the driving block 6 is located in the card slot 5 and another part is located in the second through hole 16, and a pull ring 20 is arranged at the outer end of the driving block 6.

[0022] In this embodiment, under normal conditions, the driving block 6 is driven by the second spring 19 to abut against the bottom of the card slot 5. At this time, a part of the driving block 6 is located inside the card slot 5 and the other part is located inside the second through hole 16, effectively preventing children from accidentally opening it, which is safer. When opening the door, hold the handle 3 with your hand, insert your index finger into the pull ring 20 and pull the pull ring 20 to drive the driving block 6 to move outwards. When the driving block 6 disengages from the card slot 5, the handle 3 and the linkage disk 4 can be rotated to open the door.

[0023] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
