Description

Anti-abrasion structure of electronic lock transmission data line

Technical Field

The utility model relates to an electronic lock transmission data line abrasionproof decreases structure.

Background

Present fingerprint electronic lock generally sets up fingerprint sensor on the panel, must place corresponding finger on the fingerprint sensor surface earlier when unblanking, then hold the handle of unblanking again and open the door, also place the fingerprint and unblank two steps and separately go on promptly, it is extremely inconvenient during the use, if can set up fingerprint identification sensor on the handle then can the one-hand operation, fingerprint identification ware is in case the discernment is right fingerprint then can be directly open the door with the hand of holding the handle when holding the handle, but with fingerprint identification ware setting can cause the transmission data line between fingerprint identification ware and the treater easily by the problem of wearing and tearing on the handle.

Disclosure of Invention

The utility model aims at providing a problem that the use that exists is inconvenient or transmission data line weares and teares easily in solving current electronic lock, and provide a simple structure, can make fingerprint identification ware set up in the handle and not fragile transmission data line's electronic lock transmission data line abrasionproof decreases structure.

The purpose of the utility model is realized like this: the utility model provides an electronic lock transmission data line abrasionproof decreases structure, is in including panel and pin joint handle in the panel, pin joint axle on the handle passes stretch into behind the panel is inboard, pin joint axle the inner be equipped with pin joint axle circumference location's lead ring and clamping ring make lead ring and clamping ring with pin joint axle synchronous revolution, the lead ring with the terminal surface of clamping ring contact is along radially being equipped with the outer wide lead wire groove of interior narrow, lead wire inslot port is just right the export of the epaxial lead wire passageway of pin joint, with the transmission data line warp of sensor electricity connection in the handle the export of lead wire passageway gets into behind the lead wire groove again the outer port of lead wire groove stretches out then with fix circuit board electricity on the panel is connected.

The clamping ring is also provided with a lead groove, the lead groove on the clamping ring is right opposite to the lead groove on the lead ring, and the lead groove on the clamping ring is the same as the lead groove on the lead ring in size.

The contact surfaces of the pressure ring and the lead ring are in mirror image relation with each other. Namely, the press ring and the lead ring are molded by using the same die-casting die, so that the die expenditure can be saved.

The lead groove is fan-shaped.

The transmission data line is sleeved with a protective sleeve.

The protective sleeve is a metal protective spring. The metal guard spring is a metal tension spring with a thread pitch slightly larger than or the same as the thread diameter.

Because adopted technical scheme, the handle drives the rotatory in-process of lead wire ring when opening the door, the transmission data line can not or reduce the friction of transmission data line and other parts in the panel greatly under the protection of fan-shaped lead wire groove to avoided the wearing and tearing of transmission data line, made fingerprint identification sensor can the direct mount in the handle, thereby can make operator's fingerprint identification and two actions of opening the door unite two into one, realize unblanking fast and opening the door.

Detailed Description

Fig. 1 is an exploded perspective view of a specific embodiment of an anti-wear structure for a transmission data line of an electronic lock according to the present invention, which is a fingerprint electronic lock; as can be seen from fig. 1, the anti-abrasion structure for the transmission data line of the electronic lock comprises a handle 1, a bearing 3, a decorative ring 2, a panel 4, a lead ring 5 and a press ring 50, wherein the shape and size of the press ring 50 and the size of the lead ring 5 are the same.

Referring to fig. 2, two clamping heads 51 and 52 are arranged at the center of the wire loop and are respectively matched with two clamping grooves 11 and 12 in the bearing of the handle in fig. 5, and a fan-shaped wire leading groove 53 with a narrow inner part and a wide outer part is arranged on one end surface of the wire loop.

Returning to fig. 1, during installation, the decorative ring 2 can be fixed on the panel 4 by screws, then the bearing 3 is placed in the decorative ring, the inner end of the pivot shaft 10 on the handle passes through the bearing and the decorative ring and then extends into the inner side of the panel (as shown in fig. 7 and 8), the lead ring 5 is sleeved on the pivot shaft to ensure that two clamping heads on the lead ring are respectively clamped into two clamping grooves of the pivot shaft (as shown in fig. 9) to ensure that the lead ring and the pivot shaft are circumferentially positioned (namely circumferentially synchronous), so that a transmission data line (not shown in the figure) electrically connected with a fingerprint sensor installed in the handle is positioned in a lead groove 53 of the lead ring after extending out through a lead channel 13 on the handle shown in fig. 9, then, a press ring 50 is sleeved on the pivot shaft 10 (as shown in fig. 10), after the parts for realizing other functions are mounted on the pivot shaft, a snap spring or a nut is fixed at the end of the pivot shaft, and at this time, the transmission data line is electrically connected with a circuit board on the panel after extending out through the lead slot 53. Of course, a metal guard spring can be sleeved outside the transmission data line to obtain better protection.
