Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft door handles, in particular to a special safety handle for anti-theft doors. Background Art

[0002] The handle is a key operating component of a security door. The fingerprint recognition terminal is used for identity verification and enhances security. Existing security handles designed for security doors often have the fingerprint terminal located on the front. In daily life, corrosive liquids (such as cleaning fluids and rainwater) can easily spill onto the fingerprint recognition terminal, damaging it and affecting normal use.

[0003] To solve the above problems, some solutions move the fingerprint recognition end to the back of the handle. Although this can block direct impact from water flow, water droplets will still adhere to the surface of the fingerprint recognition end. Since this position is far back, cleaning operation is difficult. When the user's finger reaches into the back and contacts the fingerprint recognition end, it will inevitably come into contact with the attached water droplets, which will lead to an increase in the fingerprint recognition error rate and reduce the convenience and practicality of product use. Therefore, a special security handle for anti-theft doors is proposed to address the above problems. Utility Model Content

[0028] See also Figures 1-6 , the utility model provides a technical solution:

[0029] A special safety handle for anti-theft doors, comprising a mounting base 1, the front end of which is rotatably connected to a splash-proof handle assembly 2, the front end surface of which is fixedly connected to a decorative panel 3; the splash-proof handle assembly 2 comprises a connecting sleeve 21, the front end of which is penetrated and fixed with a handle body 22, a card slot 23 is provided at the top of the rear end surface of the handle body 22, a finger guide channel 24, a gravity drainage groove 25 and a limit groove 27 are provided on the outer side of the handle body 22, a protective cleaning assembly 26 is installed in the middle of the rear end surface of the handle body 22; the protective cleaning assembly 26 comprises a card connection protrusion 2 61. The bottom end of the snap-fit ​​protrusion 261 is fixedly connected to a support plate 262. The outer wall of the support plate 262 is fixedly connected to a limiting belt 263. Strong magnetic sheets 264 are fixed on both sides of the surface of the support plate 262. A dust removal pad 265 is fixed on the side of the strong magnetic sheet 264. A wiper blade 266 is fixed to the front end surface of the strong magnetic sheet 264. A water absorption sleeve 267 is fixed at the center of the front end surface of the strong magnetic sheet 264. An activated carbon water absorption core 268 is embedded in the water absorption sleeve 267. A guide guard plate 269 is fixed to the top of the support plate 262. The snap-fit ​​protrusion 261 is snap-fitted to the slot 23.

[0030] As a further implementation of this solution, the outer side of the support plate 262 is a circular structure, and the interior of the support plate 262 is a cavity structure. An embedded fingerprint recognition component 6 is fixedly installed at the center of the rear end surface of the handle body 22, so that the protective cleaning component 26 can provide targeted protection for the embedded fingerprint recognition component 6.

[0031] As a further implementation of this solution, the outer side of the guide guard 269 is an arc-shaped structure, and the guide guard 269 is located between the two dust removal pads 265, and the guide guard 269 fits the dust removal pads 265;

[0032] As a further implementation of this solution, the strong magnetic sheet 264 and the connecting sleeve 21 are magnetically attracted to each other, and the center of the dust removal pad 265 and the center of the strong magnetic sheet 264 are located on the same central axis. The outer side of the deflector guard 269 has an arc-shaped structure, which can effectively change the direction of water flow. It is located between the two dust removal pads 265 and fits with them. It does not affect the normal use of the dust removal pads 265, and can quickly guide and discharge water through the arc surface when the water flow impacts.

[0033] As a further implementation of this solution, the center of the wiper blade 266 and the center of the dust removal pad 265 are located on the same central axis. There is a gap between the wiper blade 266 and the strong magnetic sheet 264. The front end of the wiper blade 266 is inclined. The height of the wiper blade 266 is 2.3 times the height of the dust removal pad 265. There is a gap between the water absorption sleeve 267 and the wiper blade 266. The front end of the water absorption sleeve 267 is provided with a circular array of notches, which can improve the flexibility of the front end of the water absorption sleeve 267. There is a gap between the wiper blade 266 and the strong magnetic sheet 264 to avoid interference between the two and affect performance. Its front end inclined structure and specific height design can efficiently scrape moisture from fingers, and cooperate with the water absorption sleeve 267 to further dry fingers, thereby improving the success rate of fingerprint recognition;

[0034] As a further implementation of this solution, the finger guide channel 24 is located in the middle of the outer side of the handle body 22, and the gravity drainage groove 25 is located at the bottom of the outer side of the handle body 22. The gravity drainage groove 25 is connected to the finger guide channel 24. The gravity drainage groove 25 is connected to the finger guide channel 24, and can drain the water flowing into the finger guide channel 24 in time to prevent water accumulation. The limiting groove 27 is located in the middle of the inner side of the finger guide channel 24, and the limiting groove 27 extends to the rear end surface of the handle body 22. The middle part of the inner side of the limiting groove 27 is fixedly connected to the positioning shaft 28. The limiting belt 263 is embedded in the interior of the limiting groove 27, and the limiting belt 263 is sleeved on the outside of the positioning shaft 28 to provide positioning and limiting functions for the protective cleaning component 26, ensuring its accurate installation position and reliable use.

[0035] As a further implementation of this solution, the front end surface of the decorative panel 3 is a curved structure, and a contact groove 4 is provided in the middle of the front end surface of the decorative panel 3. The inner side of the contact groove 4 is an arc-shaped structure, which can effectively disperse the impact force of the water flow. A drainage diversion groove 5 is provided at the bottom of the decorative panel 3. The drainage diversion groove 5 is connected to the contact groove 4 to form a complete drainage path to ensure rapid drainage of water.

[0036] Working process: When water splashes onto the handle, it first contacts the contact groove 4 on the front face of the decorative panel 3. Because the contact groove 4 is curved inside and has a drainage diversion groove 5 at the bottom, the water flows along the contact groove 4 into the drainage diversion groove 5 and then flows downstream, preventing a large amount of water from entering the handle. If the water splashes onto the handle body 22, the water above will contact the deflector plate 269 of the protective cleaning component 26. The deflector plate 269 has a curved structure, and the water will slide down along its curved surface and be discharged. It cannot directly reach the embedded fingerprint recognition component 6 on the rear face of the handle body 22, thus achieving preliminary physical protection for the embedded fingerprint recognition component 6.

[0037] When the user needs to open the door through fingerprint recognition, the user aligns the finger with the finger guide channel 24 on the outside of the handle body 22 and extends the finger into the handle body 22 along the finger guide channel 24. During the finger insertion process, the finger first contacts the dust removal pad 265 on the protective cleaning component 26. The dust removal pad 265 contacts the surface of the finger and uses its own flexibility to clean the dust in the fingerprint area of ​​the finger to prepare for subsequent fingerprint recognition. The finger continues to go deeper and contacts the wiper blade 266. The wiper blade 266 is made of hard plastic and has an inclined structure at the front end. When the finger moves relatively, the inclined surface contacts the finger surface to scrape off the moisture on the finger, reducing the interference of moisture on fingerprint recognition. After being disturbed by the wiper blade 266, the finger contacts the water absorption sleeve 267, which has an activated carbon water absorption core 268 embedded therein. The activated carbon water absorption core 268 contacts the finger and absorbs the residual moisture on the finger, making the finger surface dry, thereby ensuring the accuracy of subsequent fingerprint recognition. The dried finger reaches the embedded fingerprint recognition component 6 at the center of the rear end face of the handle body 22. The embedded fingerprint recognition component 6 collects the fingerprint information of the finger and compares it with the pre-stored fingerprint for verification. If the verification is passed, the user rotates the splash-proof handle component 2, which drives the anti-theft door lock structure to open the door. If the verification fails, the handle cannot be rotated and the anti-theft state is maintained.

[0038] When the protective cleaning component 26 needs maintenance and replacement due to long-term use, such as serious dust accumulation on the dust removal pad 265, wear of the wiper blade 266, and decline in the water absorption performance of the activated carbon water absorption core 268, the user applies appropriate external force to the protective cleaning component 26 to pull the engaging protrusion 261 out of the engaging groove 23, releasing the engaging fit. At the same time, the limiting belt 263 overcomes the matching resistance with the limiting groove 27 and the positioning shaft 28, and comes out of the limiting groove 27 without sheathing the positioning shaft 28. Then, the limiting belt 263 is pulled out of the limiting groove 27 and releases the positioning shaft 28. Under the magnetic attraction between the strong magnetic sheet 264 and the connecting sleeve 21, the protective cleaning component 26 is completely removed from the handle body 22. After cleaning or replacing the corresponding parts, the operation is reversed so that the engaging protrusion 261 is engaged in the engaging groove 23, the limiting belt 263 is embedded in the limiting groove 27 and covers the positioning shaft 28. Relying on the magnetic attraction between the strong magnetic sheet 264 and the connecting sleeve 21, the protective cleaning component 26 is firmly adsorbed on the handle body 22, the installation is completed, and the handle is restored to normal use.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
