[0057] When the handle member 20 is pressed down, the convex block 343 rotates clockwise with the handle member 20. During the rotation, the convex block 343 will press the first torsion rod 373 to rotate towards the arc-shaped positioning plate 326 together, while the second torsion rod 374 does not rotate due to the block of the second positioning block 328 until the door lock is opened. When the force on the handle member 20 is removed, the first torsion rod 373 will drive the convex block 343 to reset to the origin counterclockwise under the elastic action of the torsion spring 37;

[0058] When the handle member 20 needs to be reversed by 180 degrees, loosen the reversing member 38, rotate the handle member 20 counterclockwise by 180 degrees, and then tighten the reversing member 38. At this time, the convex block 343 is located at one end of the second torsion rod 374 away from the arc-shaped positioning plate 326, and the reversing member 38 is located at one end of the first torsion rod 373 away from the arc-shaped positioning plate 326. The convex block 343 and the reversing member 38 are both located between the two torsion ends 372. When the handle member 20 is pressed down in the reverse direction, the convex block 343 rotates counterclockwise with the handle member 20. During the rotation, the convex block 343 will press the second torsion rod 374 to rotate towards the arc-shaped positioning plate 326 together, while the first torsion rod 373 does not rotate due to the block of the first positioning block 327 until the door lock is opened. When the force on the handle member 20 is removed, the second torsion rod 374 will drive the convex block 343 to reset to the origin clockwise under the elastic action of the torsion spring 37.

[0059] Please refer further to Figures 2 to 4 、 Figures 10 to 12 、and Figures 16 to 18, in this embodiment, the door handle device further includes an anti-peeping unlocking module 70.

The guide post 115, the two baffle plates 116, and the two second studs 117 all protrude from one side of the plate body 114. The two baffle plates 116 are oppositely arranged and are both located between the two second studs 117. The guide post 115 is located between the two baffle plates 116. The dial hole 112, the first through hole 111, and the two limiting grooves 113 are all provided on the plate body 114. The guide post 115 is provided with a fifth threaded hole 1151. The second stud 117 is provided with a sixth threaded hole 1171. The base 721 slides on the plate body 114 and is located between the two baffle plates 116. The stop pin 71 is further provided with a strip-shaped hole 713. The guide post 115 is inserted into the strip-shaped hole 713. The fourth fastener 76 is threadedly installed on the fifth threaded hole 1151 and covers part of the stop pin 71. The fifth fastener 77 is installed on the sixth threaded hole 1171 and covers part of the stop pin 71 to limit the anti-peephole unlocking module 70. The fourth fastener 76 and the fifth fastener 77 are both screws.

[0062] The anti-peephole unlocking module 70 further includes an indicating film 78 located in the accommodating space 14. The indicating film 78 is installed on the side of the base 721 away from the stop pin 71. At least two color blocks of different colors are coated on the indicating film 78. The indicating film 78 is correspondingly arranged with the dial hole 112. Pushing the switch push button 72 can display different color blocks in the dial hole 112. The two color blocks can be red and green colors to prompt the user to confirm the on-off state of the anti-peephole unlocking device.

[0063] The present invention also discloses an intelligent door lock, which includes an electronic lock body 80, an indoor handle lock 90 and an outdoor handle lock 100. The indoor handle lock 90 includes the door handle device as described above. Except for not having an anti-peeping unlocking module 70 and an anti-lock structure, the rest of the structure of the outdoor handle lock 100 is the same as that of the indoor handle lock 90. The electronic lock body 80 is a prior art and can adopt the electronic lock body disclosed in the patent CN114109146A. The square steel 40 of the indoor handle lock 90 and the outdoor handle lock 100 are inserted into the shaft hole 81 of the electronic lock body 80 from both sides of the electronic lock body 80, and the electronic lock body 80 is linked through the corresponding square steel 40 to drive the lock tongue 82 on the electronic lock body 80 to extend or retract.

[0064] In summary, the cover plate 12 of the present invention is made by stamping process, and a plurality of convex bumps 122 can be stamped on the cover body 121 of the cover plate 12. There is no need to use a die-casting mold in the production of the cover plate 12. At the same time, a plurality of first through holes 124 can be directly stamped during the stamping process. The first through holes 124 sequentially penetrate through the cover body 121 and the convex bumps 122. After the first fastener 35 passes through the first through holes 124 on the cover plate 12 and is connected to the first threaded hole 322 on the corresponding fixing seat 32, the fixing seat 32 can be installed on the cover plate 12 without using a tapping machine to process threaded holes on the cover plate 12. The processing cost of the intelligent door lock is low, the assembly is very convenient, and it is suitable for large-scale promotion.

[0065] The above embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
