Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to a door lock handle structure. Background Art

[0002] The handle structure is an important structural component of the door lock. The existing handle structure with fingerprint unlocking function, as shown in the patent application number CN201921496177.X, includes a handle body and a fingerprint identifier arranged on the surface of the handle body. Although the above-mentioned handle structure facilitates fingerprint unlocking, the fingerprint identifier is exposed on the outside of the handle body. For door locks with outward-opening door installation, if there is a side wall on the outside of the door leaf, after the door leaf is opened outward, the side of the handle structure close to the fingerprint identifier is likely to directly hit the side wall, causing damage to the fingerprint identifier. Utility Model Content

[0003] In order to solve the shortcoming that the fingerprint identifier of the existing handle structure is easily damaged by the impact of the wall, the utility model proposes a door lock handle structure to protect the fingerprint identifier and reduce damage.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A door lock handle structure includes a panel, a handle body, a fingerprint identifier and an elastic telescopic structure. The handle body is rotatably connected to the outside of the panel and is transmission-connected to the lock body of the door lock. The fingerprint identifier is arranged on the outside of the handle body. The handle body is provided with an annular groove around the fingerprint identifier on the outside. The elastic telescopic structure includes a slip ring and a spring. The slip ring is slidably connected in the annular groove. The end of the slip ring protrudes from the outside of the handle body. The spring is installed in the annular groove and connected to the slip ring for resetting the slip ring.

[0006] Through the above arrangement, the slip ring protrudes from the outside of the handle body around the fingerprint identifier. When it is hit by a wall, the wall first hits the outer end of the slip ring, and the spring is compressed to form a buffer to prevent the wall from hitting the fingerprint identifier, or reduce the impact force of the wall on the fingerprint identifier to prevent damage to the fingerprint identifier.

[0007] Furthermore, the handle body includes a base and a cover plate, the base is rotatably connected to the outside of the panel, a mounting groove adapted to the fingerprint identifier is provided on the outside of the base, the cover plate is locked on the outside of the base and abuts against the outside of the fingerprint identifier, a window is provided on the cover plate to press the fingerprint identifier, the annular slide groove includes a first groove portion passing through the inner and outer sides of the cover plate, and a second groove portion provided on the outside of the base, the slip ring includes a limiting portion slidably connected to the second groove portion, and a slip ring body passing through the first groove portion, and one end of the slip ring body away from the limiting portion protrudes on the outside of the cover plate.

[0008] Through the above arrangement, it is convenient to install the fingerprint identifier and the elastic telescopic structure on the handle body.

[0009] Furthermore, one end of the spring abuts against the bottom of the second groove, and the other end abuts against the limiting portion.

[0010] Furthermore, the outer diameter of the limiting portion is larger than the outer diameter of the first groove portion.

[0011] The above arrangement prevents the slip ring from being pulled out.

[0012] Furthermore, the height of one end of the slip ring body away from the limiting portion protruding from the outside of the panel is greater than 5 mm and less than 10 mm.

[0013] The above settings make it easier for users to perform fingerprint recognition while also ensuring a better buffering effect.

[0014] Furthermore, rounded corners are provided on the inner and outer peripheries of one end of the slip ring body away from the limiting portion.

[0015] The above arrangement improves the comfort of the user when pressing the slip ring.

[0016] Furthermore, a slot is provided on the outside of the base, a latch adapted to the slot is provided on the inside of the cover, the latch is inserted into the slot, a screw is provided on the inside of the base, the screw passes through the base and is threadedly connected to the latch.

[0017] Through the above arrangement, the cover is locked on the base by means of latches and screws. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 2 is a cross-sectional view of the handle structure of the embodiment. DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0021] like Figures 1 to 2 As shown, a door lock handle structure includes a panel 2, a handle body 3, a fingerprint identifier 4 and an elastic telescopic structure. The handle body 3 is rotatably connected to the outside of the panel 2 and is transmission-connected to the lock body of the door lock. The fingerprint identifier 4 is arranged on the outside of the handle body 3. The handle body 3 is provided with an annular groove 5 around the fingerprint identifier 4 on the outside. The elastic telescopic structure includes a slip ring 6 and a spring 7. The slip ring 6 is slidably connected in the annular groove 5. The end of the slip ring 6 protrudes from the outside of the handle body 3. The spring 7 is installed in the annular groove 5 and is connected to the slip ring 6 for resetting the slip ring 6.

[0022] Through the above arrangement, the slip ring 6 protrudes outwardly from the outside of the handle body 3 around the fingerprint identifier 4. When the handle 4 is hit by a wall, the wall first hits the outer end of the slip ring 6, and the spring 7 is compressed to form a buffer to prevent the wall from hitting the fingerprint identifier 4, or to reduce the impact force of the wall on the fingerprint identifier 4 to prevent the fingerprint identifier 4 from being damaged.

[0023] The panel 2 of the present application is installed on the outside of the door leaf, and the handle body 3 is basically an L-shaped structure. One end is vertically rotatably connected to the outside of the panel 2 and is transmission-connected to the lock body of the door lock, and the other end is parallel to the panel 2, which is convenient for manual rotation of the handle body 3; the fingerprint identifier 4 is basically circular and installed on the outside of the handle body 3 and close to the corner of the handle body 3 for thumb pressing; the slip ring 6 is adapted to the annular slide groove 5 to prevent the slip ring 6 from shaking, and the ratio of the outer diameter of the slip ring 6 to the outer diameter of the fingerprint identifier 4 is greater than 1.1 and less than 1.2, so that the inner wall of the slip ring 6 is close to the fingerprint identifier 4, ensuring the protection effect of the slip ring 6 on the fingerprint identifier 4; normal use When the user's thumb needs to press the fingerprint identifier 4, it first contacts the outer end of the slip ring 6. After continuing to press, the spring 7 is deformed, and the slip ring 6 moves inward along the annular groove 5 and finally presses on the fingerprint identifier 4. After successful recognition, the handle body 3 is rotated to unlock. After releasing the thumb, the spring 7 is reset and the slip ring 6 returns to its initial position; after opening the door leaf outward, the door leaf moves outward under the action of inertia. When there is a wall outside the door leaf, the wall hits the slip ring 6 in advance. Under the buffering action of the spring 7, the wall can be prevented from hitting the fingerprint identifier 4, or the impact force of the gun body on the fingerprint identifier 4 can be reduced to prevent the fingerprint identifier 4 from being damaged.

[0024] As an implementation method, the handle body 3 includes a base 31 and a cover plate 32. The base 31 is rotatably connected to the outside of the panel 2. A mounting groove 8 adapted to the fingerprint identifier 4 is provided on the outside of the base 31. The cover plate 32 is locked on the outside of the base 31 and abuts against the outside of the fingerprint identifier 4. A window 9 is provided on the cover plate 32 to press the fingerprint identifier 4. The annular slide groove 5 includes a first groove portion 51 passing through the inner and outer sides of the cover plate 32, and a second groove portion 52 provided on the outside of the base 31. The slip ring 6 includes a limiting portion 61 slidably connected to the second groove portion 52, and a slip ring body 62 passing through the first groove portion 51. The end of the slip ring body 62 away from the limiting portion 61 protrudes from the outside of the cover plate 32.

[0025] Through the above arrangement, it is convenient to install the fingerprint identifier 4 and the elastic telescopic structure on the handle body 3.

[0026] The handle body 3 of the present application is a split structure. During installation, the fingerprint identifier 4 is first placed in the installation groove 8, the spring 7 and the limiting portion 61 of the slip ring 6 are installed in the second groove 52, and then the cover 32 is covered. The slip ring body 62 of the slip ring 6 passes through the first groove 51, and finally, the cover 32 is locked on the base 31.

[0027] As an implementation method, one end of the spring 7 abuts against the bottom of the second groove 52 , and the other end abuts against the limiting portion 61 .

[0028] As an implementation manner, the outer diameter of the limiting portion 61 is greater than the outer diameter of the first groove portion 51 .

[0029] The above arrangement prevents the slip ring 6 from being pulled outward.

[0030] As an implementation method, the height of one end of the slip ring body 62 away from the limiting portion 61 protruding from the outside of the panel 2 is greater than 5 mm and less than 10 mm.

[0031] The above settings make it easier for users to perform fingerprint recognition while also ensuring a better buffering effect.

[0032] The greater the height of the slip ring 6 protruding from the panel 2 of the present application, the better the buffering effect. However, when the user performs fingerprint recognition, the greater the distance the user needs to press the slip ring 6, the more troublesome it is. When the height of the protruding panel 2 at the outer end of the limiting body is greater than 5mm and less than 10mm, user fingerprint recognition is also more convenient while ensuring the buffering effect.

[0033] As an implementation method, rounded corners are provided on both the inner and outer peripheries of one end of the slip ring body 62 away from the limiting portion 61 .

[0034] Through the above arrangement, the comfort of the user pressing the slip ring 6 is improved.

[0035] As an implementation method, a slot 10 is set on the outside of the base 31, and a pin 11 adapted to the slot 10 is set on the inside of the cover 32. The pin 11 is inserted into the slot 10. A screw 12 is set on the inside of the base 31, and the screw 12 passes through the base 31 and is threadedly connected to the pin 11.

[0036] Through the above arrangement, the cover 32 is locked on the base 31 by the latch 11 and the screw 12 .

[0037] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
