Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further illustrated, but protection scope of the present invention is not limited to this.
As shown in Figure 1, Figure 2, Figure 3 shows, the angle demodulator with rotary switch provided by the invention, comprise do not cover 1, band axis cam 2, sunk screw 3, securing cover plate 4, attached dish 5, two fork bodies 6, two springs 7, master seat 8, knob 9.As shown in Figure 6, describedly with axis cam 2, comprise wheel disc and be welded on the axle on wheel disc, on described wheel disc, have two arc-shaped slots 201 that distribute with wheel disc Central Symmetry.As shown in Figure 5, have roller 601, mobile guide pillar 602, spring guide pillar 603 on described fork body 6, described mobile guide pillar 602, spring guide pillar 603 are positioned on a side, and described roller 601 is positioned on end face; Move relative side, guide pillar 602 sides, place with external tooth and be provided with external tooth.
As shown in Figure 4, described master seat 8 has boss 801, the axle center that can insert attached dish 5 inside and is provided with axial hole 802, and described boss 801 is provided with and laterally runs through the chute 803 of boss 801 and circular hole radially.Two springs 7 are enclosed within respectively on the spring guide pillar 603 of two fork bodies 6, and the mobile guide pillar 602 of described two fork bodies 6 inserts chute 803 in opposite directions.The position of described radially circular hole is corresponding with the position of spring guide pillar 603, when two fork bodies 6 along master seat 8 radially, while moving to the direction near master seat 8 axle center, spring guide pillar 603 can enter radially circular hole, makes to pitch the motion of body 6 freely.Preferably, at the root of pitching body 6 upper spring guide pillars 603, be provided with annular groove, one end of described spring 7 is embedded in described circular groove, convenient for assembly.
As shown in Figure 6, on described securing cover plate 4, have be positioned at the through hole at center, with axisymmetric two breach 401 in center.Securing cover plate 4 is positioned at fork body 6 tops, is fixed on boss 801 upper-end surfaces, and described roller 601 is positioned at breach 401 places of securing cover plate 4.Described attached dish 5 is enclosed within on the boss 801 of master seat 8 and attached dish 5 can rotate around master seat 8 axle center.The inwall of attached dish 5 is provided with the internal tooth being meshed with the external tooth shape of pitching on body 6.Do not cover 1 and be fixed on the upper-end surface of described attached dish 5, do not cover 1 and adopt gluing fastening with attached dish 5.
As shown in Figure 7, the rollers 601 of 802, two fork bodies 6 of axial hole of the described insertion of the axle with axis cam 2 master seat 8 embed respectively in two arc-shaped slots 201 on wheel disc.The free-ended end face of the described axle with axis cam 2 is provided with screw (in figure for illustrating), and the free-ended end of axle is flat structure 202.Described knob 9 centers are provided with the flat counterbore 901 conforming to the free end end cross-sectional shape of described axle.Described knob 9 be positioned at master seat 8 below, described flat structure 202 coordinates with flat counterbore 901, band axis cam 2 is fixing by sunk screw 3 with knob 9, sunk screw 3 coordinates with the screw in axial end.
With the angle demodulator of rotary switch, the roller 601 of fork body 6 is positioned at the arc-shaped slot 201 with axis cam 2 wheel discs.The rotation band movable band axis cam 2 of knob 9 rotates, and indirectly realizes fork body 6 moving radially along master seat 8.Knob 9 is connected with band axis cam 2, and turning knob 9, can make to be with axis cam 2 synchronous rotaries, and knob rotating range is 0-90 °.Under nature, as shown in Figure 8, under the elastic force effect of spring 7, fork body 6 is along master seat 8 radial dilatation, and on fork body 6 sides, the interlocking of the interlocking member of attached dish 5 internal surfaces, attached dish 5 is fixed with the relative angle of master seat 8, can not change.When turning knob 9, band axis cam 2 is by roller 601 band moving fork body 6 motions, fork body 6 radially moves to master seat axle center along master seat 8, spring is compressed, on fork body 6 sides, the interlocking member of attached dish 5 internal surfaces departs from, release, now the state of described angle demodulator as shown in Figure 9, now can adjust by master seat 8 and attached dish 5 relative angles.When unclamping knob 9, spring 7 recovers deformation, promoting fork body 6 radially moves to the direction away from master seat axle center along master seat 8, on fork body 6 sides, the interlocking member of attached dish 5 internal surfaces interlocks again, the relative angle of master seat 8 and attached dish 5 is fixed, knob 9 returns to initial position, realizes angle adjustment.
In the above-described embodiments, the internal tooth of attached dish 5 internal surfaces, be positioned at the external tooth of fork on body 6 sides, its effect is can be intermeshing, realize attached dish 5 and the interlocking of pitching body 6, therefore, other interlocking structures that can realize this function also can be used in described angle demodulator, for example, on fork body 6 sides, dead bolt is set, and the groove conforming to described dead bolt shape is set on attached dish 5.
Described embodiment is preferred embodiment of the present invention; but invention is not limited to above-mentioned mode of execution; in the situation that not deviating from flesh and blood of the present invention, any apparent improvement, replacement or modification that those skilled in the art can make all belong to protection scope of the present invention.
