Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, but the present invention is not limited thereto.
As shown in fig. 1 and 2, a simplified fingerprint module mounting structure includes a mounting case for mounting on a mounting plate 14 and a mounting plate 3. The back of installation casing is equipped with a pair of screwed joint 4 of cooperation installation piece 3, is equipped with a pair of mounting hole 3 and a pair of mounting screw 13 of cooperation screwed joint 4 on the installation piece 3, and still is equipped with a pair of supporting screw 6 and a pair of screw hole 7 that cooperate supporting screw 6 on the installation piece 3, and mounting hole 5 and screw hole 7 all are located the both ends of installation piece 3, and screw hole 7 is located the outside of mounting hole 5. The installation casing includes that the installation encloses 1 and is located the positive spacing collar 2 of installation circle 1, and the back of installation circle 1 is equipped with backplate 8, and screwed joint 4 installs on backplate 8. The backboard 8 is provided with four thread mounting posts 9 matched with the fingerprint module and a thread hole 10 for routing, the thread hole 10 is positioned in the middle of the backboard 8, and the four thread mounting posts 9 are uniformly distributed on the outer ring of the backboard 8. The screwed joint 4 is located the centre of two of them screw thread erection columns, and two screwed joint mutual symmetry sets up. The inner wall of the mounting ring 1 is provided with a plurality of limiting steps 11 and limiting buckles 12 which are matched with the fingerprint module.
During assembly, the fingerprint module is arranged in the mounting ring from the front side of the mounting ring, and is firmly fixed through the threaded mounting column after being limited by the limiting step (mainly used for limiting the fingerprint reading part of the fingerprint module) and the limiting buckle (mainly used for limiting the circuit board of the fingerprint module); then, the mounting ring is arranged in the mounting hole of the mounting plate (generally, a plate with two operable sides such as a file cabinet door or a drawer door), the front side of the mounting plate is limited through the limiting ring, and the threaded joint penetrates through the mounting hole of the mounting plate and then is fixed with the back side of the mounting plate through the mounting piece.
As shown in fig. 3, when the thickness of the mounting plate is equal to or greater than the sum of the thickness of the mounting ring and the length of the threaded joint, the mounting ring is directly fixed to the mounting plate by the mounting piece and the mounting screw.
As shown in fig. 4, when the thickness of the installation plate is smaller than the sum of the thickness of the installation ring and the length of the threaded joint, if the installation ring is installed on the installation plate only by the installation sheet and the installation screw, the installation ring will shake and cannot be fixed; therefore, the mounting plate needs to be fixed on the threaded connector through the mounting screw, and then the supporting screw rod needs to be rotated until the front end of the supporting screw rod tightly abuts against the back surface of the mounting plate, so that the mounting ring is firmly abutted against the mounting plate.
The utility model provides a fingerprint module is the same with the part and the theory of operation that conventional fingerprint module contains on the market homogeneous, so do not describe in detail.
The utility model discloses to the installation of small batch volume fingerprint module specially, need not special die sinking, reduce the cost of singleton mounting structure, design the structure of supporting screw and screw hole simultaneously on the mounting pad for its installation panel that is applicable to multiple thickness enlarges application scope.
