Abstract

An embodiment of the utility model discloses a coding knob. The coding knob comprises a hard-rubber knob cap (1001) and a hard-rubber knob shaft (1002). An internal part of the knob shaft (1002), which is parallel to a device shaft, is provided with a hollow portion (1003). An opening direction of the hollow portion (1003) is along one side of the knob cap (1001). The hollow portion (1003) is filled with a flexible glue (1004). When the coding knob is affected by a positive impact, the flexible glue on the top of the coding knob firstly contacts with the impact so as to buffer parts of the impact. And the rest impact can be directly transmitted to a surface shell through the outer-edge hard rubber of the coding knob so that impact-resistant performance of the coding knob can be increased. There is enough space between the top of the device shaft and the knob cap so that the device shaft is not damaged even if the knob is deformed.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model clearer; To combine accompanying drawing that the utility model is done to describe in detail further below; Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

The utility model embodiment provides a kind of coding knob, shown in Fig. 2 A and 2B, comprising:

The knob cap 1001 of ebonite and the rotation axis 1002 of ebonite;

Have hollow-out parts 1003 on above-mentioned rotation axis 1002 inside and the device axle parallel direction, above-mentioned hollow-out parts 1003 opening directions are in above-mentioned knob cap 1,001 one sides; Be filled with flexible glue 1004 in above-mentioned hollow-out parts 1003.

When revolving the coding button when receiving forward impact, the contact earlier of coding top knob portion flexible glue cushions a part of impulse force, and surplus energy can directly pass on the face-piece through coding knob outer rim ebonite, can promote coding knob anti-collision performance.Device axle top and knob cap have enough spaces, even the knob distortion can the damage device axle yet.

Preferably, as shown in Figure 3, above-mentioned hollow-out parts 1003 is divided into outer ring and inner ring with rotation axis 1002, and above-mentioned inner ring is to be fixedly connected portion with the device axle, is the outer ring away from a side of device axle; Above-mentioned inner ring thickness is greater than above-mentioned outer ring thickness.The outer ring of coding knob is designed to the engraved structure of thin-walled, encloses defencive function outward, in enclose the effect of immobilising device axle.Both link to each other through thin-walled, can the torsion of rotation be delivered on the device, realize the mode of its turn, can rely on the deformable characteristic of thin-walled again, and impulsive force is disperseed to alleviate, and play the effect of protection device.

Alternatively, gap, above-mentioned hollow-out parts 1003 cross section is more than or equal to 0.5 millimeter.Smooth and easy for the knob start that guarantees to encode, reserve enough gaps with the face-piece wall.When receiving side knock, the coding knob can be to the face-piece move.Most impulse force is transmitted on the face-piece.Because coding knob outer ring links to each other through hollow out formula thin-walled with inner ring, the distortion of thin-walled can absorb the displacement of outer ring, and impulsive force can be directly delivered on the device.

Alternatively, above-mentioned hollow-out parts 1003 is the hollow-out parts 1003 of cover beer structure; Above-mentioned hollow-out parts 1003 is filled with flexible glue 1004 and comprises: the knob cap 1001 of above-mentioned ebonite and the rotation axis 1002 of ebonite are connected for cover beer formula with flexible glue 1004, and flexible glue 1004 is filled in the hollow-out parts 1003 of above-mentioned cover beer structure.Soft or hard glue combines through the mode of overlapping beer and prevents to peel off.

Further, above-mentioned hollow-out parts 1003 has interspersed structure.Soft or hard glue combines through the mode of cover beer, and is designed to intert structure each other and prevents to peel off.

Alternatively, has groove 1005 between the knob cap 1001 of above-mentioned ebonite and the rotation axis 1002 of ebonite, the side that the opening direction of groove 1005 is connected with the device axle at above-mentioned rotation axis 1002.As shown in Figure 4, the face-piece 2001 of equipment can be stuck in above-mentioned groove 1005, and device axle 2002 is fixedly connected with above-mentioned rotation axis 1002.

Preferably, as shown in Figure 5, can consult Fig. 4 in the lump, above-mentioned knob cap 1001 is circular-arc near an end of above-mentioned groove.Circular arc place part is shown in the circle amplifier section of circle part and arrow points among Fig. 5.

The coding knob structure that the utility model is implemented to provide has following characteristics: 1, the gap is greater than 0.5mm, plastic deformation when can effectively avoid being hit; 2, coding knob and loam cake contact-making surface is designed to little circular arc, guarantees that contact-making surface is very little, and and face-piece between the space stay enough big, guarantee that the friction of knob cap and face-piece is enough little, minimizing injures when being hit.3, the coding knob adopts the soft or hard gum forming.It is stressed that organization plan has guaranteed to make flexible glue as far as possible, the stressed impact that reaches switch shaft of corresponding minimizing ebonite.4, be designed to the thin wall hollow structure between the outer ring of coding knob and the inner ring.Employing soft or hard glue Shooting Technique, the interspersed structural design of soft or hard glue, contact contact reduce friction, the ebonite partial design becomes the thin wall hollow structure; Design the scheme of big gap through the plastic deformation relieve stresses and guarantee dropproof damage, structural member assembles simple and convenient less.

More than be merely the preferable embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model embodiment discloses; The variation that can expect easily or replacement all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with the protection range of claim.
