Abstract

The utility model discloses a mounting structure for a handle of a fingerprint lock, comprising a handle and a handle shaft whose one end extends to form a connecting portion that is matched with the inner cavity of the handle. The utility model is characterized in that the mounting structure for the handle of the fingerprint lock also comprises a U-shaped spring leaf fastened on the connecting portion of the handle shaft. Each side edge of the U-shaped spring leaf is respectively provided with an outward arcuate bulge; the U-shaped opening portions are respectively warped outward to form kinks; the inner cavity wall of the handle and the outer side of the spring leaf are fastened in fixing connection. The utility model has convenient installation, the surface of the handle is smooth and fluent, with no trace of the fixation by a screw, and is suitable for the use of the high-grade lockset of the fingerprint lock, etc, with firm and reliable fixation.

Description

Fingerprint Lock handle mounting structure

Technical field

The utility model relates to a kind of annex of lock, is specifically related to the handle on a kind of Fingerprint Lock and the syndeton of handle between centers.

Background technology

Handle on the door lock normally after the lock core installation, is fixedly mounted on the rotating handle axle again, when maintenance lock core or replacing door lock, need take off handle earlier, thereby handle and handle between centers should adopt dismountable fixed structure.Existing handle mounting structure, normally on handle, offer screw hole, adopt screw that handle is fixed on the handle axle, this mounting structure can be realized the fixing and dismounting of handle and handle axle, when still handle being installed, needs to use instruments such as screwdriver, operate more loaded down with trivial details, simultaneously, can stay screw or screw hole, influence the outward appearance of handle on the handle surface.

Development along with technology, fingerprint technique enters safety-security area, the application of Fingerprint Lock begins continuous increase, because it is higher that Fingerprint Lock and standard machinery lockset are compared price, except require its have easy to use, needn't carry key, can write down outside the functional characteristics such as the person of unblanking and uncaging time, the customer also has higher requirement to the outward appearance of Fingerprint Lock, wishes the handle smooth surface smoothness of Fingerprint Lock.

Summary of the invention

The utility model purpose provides a kind of being convenient to and installs and fixes, and the handle surface does not have the Fingerprint Lock handle mounting structure that vestige is installed.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Fingerprint Lock handle mounting structure, comprise handle and handle axle, described handle axle one end extends to form the connecting portion that cooperates with the handle inner chamber, also include spring leaf, described spring leaf takes the shape of the letter U, be arranged on the connecting portion of handle axle, it is protruding to be respectively equipped with outside bow on each side of described U-shaped spring leaf, the respectively outside warpage of U-shaped peristome constitutes bending, and the internal chamber wall of described handle is fixed with the lateral surface of spring leaf and is connected.

In the technique scheme, the outside warpage of the peristome of U-shaped spring leaf forms bending, when overlapping handle thereon, this peristome can be fitted with internal chamber wall, makes it to be difficult for sliding, simultaneously, bow on the handle internal chamber wall pressuring spring sheet side is protruding, because elastic reaction, the power of the outside warpage of spring leaf opening portion is bigger, thereby the opening portion that makes spring leaf tightly props up the inner chamber of handle, and handle is fixed.

In the technique scheme, two sides that engage with spring leaf on the connecting portion of described handle axle are the plane.

Further technical scheme has groove on the connecting portion of described handle axle, and the degree of depth of groove is not more than the thickness of spring leaf, and described spring card is located in the groove.

In the technique scheme, for avoid spring leaf inboard with the handle axle between skid handle come off, can the U-shaped of spring leaf in the middle part of with the handle axle between be connected by screw.During installation, at first spring leaf is screwed, then handle is press fit on the handle axle in handle axle outer end.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1. because the utility model is provided with spring leaf, during installation, only need the handle cover is set on the handle axle, promptly engage mutually, realize fixing by spring leaf, thus easy for installation;

2. the utility model is fixedly connected by spring leaf, handle smooth surface smoothness, and no screw vestige is fit to high-grade lockset uses such as Fingerprint Lock;

3. spring leaf of the present utility model, compare with the ball reed, except making the engaging of handle axle by bending protruding elasticity, also the peristome at the U-shaped sheet is provided with outside warpage, utilizes the handle inner chamber to make open end that the power of stronger outside warpage be arranged to bending protruding compressing power, thereby has guaranteed the fastening of handle, through actual tests, can't handle be pulled up with hand, and will assist dismounting by the employing instrument, thereby guarantee the reliability of using.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: referring to accompanying drawing 1 to shown in the accompanying drawing 4, a kind of Fingerprint Lock handle mounting structure, comprise handle 1, handle axle 3 and spring leaf 5, described handle axle 3 one ends extend to form the connecting portion 4 that cooperates with handle inner chamber 2, two sides that engage with spring leaf 5 on the connecting portion 4 are the plane, have groove 8 on it, the degree of depth of groove 8 is not more than the thickness of spring leaf 5, the width of the width of groove 8 and spring leaf 5 is suitable, described spring leaf 5 takes the shape of the letter U, be arranged in the groove on handle axle 3 connecting portions, be respectively equipped with outside bow protruding 6 on each side of described U-shaped spring leaf 5, the respectively outside warpage of U-shaped peristome constitutes bending 7, and the internal chamber wall of described handle 1 is fixed with the lateral surface of spring leaf 5 and is connected, and fixedlys connected by screw 9 in the middle part of the U-shaped of spring leaf 5 with between the handle axle 3.

During installation, shown in accompanying drawing 4, at first spring leaf 5 is snapped in the groove 8 of handle axle connecting portion, make spring leaf 5 be fixed on handle axle 3 outer ends with screw 9, load onto Fingerprint Lock housing 10, the connecting portion 4 of handle axle stretches out in the hole of Fingerprint Lock housing 10, handle 1 is press fit on the connecting portion 4 of handle axle then.At this moment, it is protruding 6 that the circle of handle inner chamber 2 pressuring springs bottoms is bent, and makes the warpage of spring opening portion that more serious trend be arranged, thereby make the spring opening portion tightly prop up the inner chamber 2 of handle, and handle 1 can not be pulled down easily.
