Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
Since current hand arteries and veins identification device is all integral structure, this results in hand arteries and veins identification device non-dismountable also not
Can partial replacement, when section components damage when, can not only replacement damage component.In view of this, being provided in the embodiment of the present application
A kind of hand arteries and veins identification device.
It refering to fig. 1, is a kind of hand arteries and veins identification device schematic diagram in the embodiment of the present application.Hand arteries and veins identification device include palmrest 1,
Support frame 2, collet 3, the hand arteries and veins sensor 4 of both ends open.Wherein, hand arteries and veins sensor 4 is installed in support frame 2.Palmrest 1 is removable
That unloads is mounted at the upper end opening of support frame, and the middle part of palmrest 1 be formed with hollow-out parts 11 so that tester palm image
It can be transferred to hand arteries and veins sensor 4, collet 3 is mounted at (not shown) at the lower ending opening of support frame 2.
In this way, the palmrest and collet of hand arteries and veins identification device are detachably arranged on support frame, difference can be met
The use demand of scene.If the hand arteries and veins sensor degradation being installed in support frame, can only more hand-off arteries and veins sensor, no replacement is required
Entire hand arteries and veins identification device.
Refering to Fig. 2 a and Fig. 2 b, Fig. 2 a be in the embodiment of the present application collet towards palmrest schematic surface；Fig. 2 b is this Shen
It please support frame schematic diagram in embodiment.Specifically, the marginal surface of collet 3 towards the palmrest is formed with first annular groove
71, the lower edge of support frame 2 protrudes into first annular groove 71 to be clamped with first annular groove 71, to realize collet 3 and branch
Support 2 is detachably connected；Alternatively, the lower end surface of support frame 2 is formed with second annular groove 43, collet 3 is towards the palmrest 1
Surface be formed with annular protrusion (not shown), annular protrusion stretch in second annular groove with second annular
Groove 43 is clamped, to realize being detachably connected for collet 3 and support frame 2.
Refering to Fig. 3 and Fig. 2 b, Fig. 3 is that the palmrest of hand arteries and veins identification device provided by the embodiments of the present application shows towards shoe surface
It is intended to.Wherein, the upper end of support frame 2 is formed with first groove of circle 42, and palmrest is sheathed on the outside of first groove；Support frame
Snap component 41 is equipped between 2 upper end and palmrest 1, to realize that the palmrest is removably connect with support frame as described above.
Dismountable connection structure (as the aforementioned first groove, snap component), due to detachable so more unstable.
Based on this demand, as shown in Figure 2 b, in hand arteries and veins identification device provided by the embodiments of the present application, the lower end of support frame 2 is formed with
Notch 44 is formed with retention bead 74 as shown in Figure 2 a on collet 3, retention bead 74 stretches to notch 44 to collet 3 and branch
Circumferential limit is carried out between support 2.
By retention bead and notch, it can be avoided and rotate in a circumferential direction between collet and support frame, make hand arteries and veins identification dress
It sets more stable.
It is that the collet of hand arteries and veins identification device provided by the embodiments of the present application deviates from palmrest schematic surface refering to Fig. 4.Its
In, collet 3 is evenly distributed with non-slip mat 73 away from the surface of palmrest.Preferably, collet 3 is evenly distributed with away from 1 surface of palmrest
4th groove 72 inlays non-slip mat 73 in the 4th groove 72.
In such manner, it is possible to increase the frictional force between hand arteries and veins identification device and table top, anti-locking apparatus receives outside when in use
Lateral Force and move, ensure that hand arteries and veins identification device is more stable when in use, safer, allow tester experience when
It is more comfortable.
In a kind of possible embodiment, as shown in figure 5, it is the embodiment of the present application palmrest away from the signal of support frame surface
Figure.For palmrest 1 in the surface of support frame 2, the side of hollow-out parts 11 is formed with the finger position restrainer for limiting finger position
Structure 32, hollow-out parts 11 are formed with the wrist position-limit mechanism 31 for limiting wrist location away from the side of finger position-limit mechanism 32.
Specifically, finger position-limit mechanism 32 include the second groove 321 of multiple restriction finger positions being spaced apart and
Multiple the first protrusions 322 for being used to limit position between two fingers.Wrist position-limit mechanism is two the second protrusions 311, described
Third groove 312 is formed between two the second protrusions.
In this way, palm can be allowed to be more easily aligned hand arteries and veins sensor by finger position-limit mechanism and wrist position-limit mechanism, i.e.,
Make to be the lesser tester of hand-type, also palm accurately can be placed on hand arteries and veins according to finger position-limit mechanism and wrist position-limit mechanism
On identification device, recognition effect and accuracy of identification can be improved.
When it is implemented, refering to Fig. 5, each second groove 321 of finger position-limit mechanism 32 is equipped with non-slip mat 323, two
The third groove 312 formed between a second protrusion 311 is equipped with flexible pad 313.
In this way, can be avoided since hand arteries and veins identification device material is harder, caused tester by flexible pad and non-slip mat
The problem of experience sense difference keeps tester more comfortable when using hand arteries and veins identification device.
Obviously, those skilled in the art can carry out various modification and variations without departing from this hair to the embodiment of the present invention
Bright spirit and scope.In this way, if these modifications and changes of the present invention belongs to the claims in the present invention and its equivalent technologies
Within the scope of, then the present invention is also intended to include these modifications and variations.
