Detailed description of the invention
The invention will be further described with the following Examples.
As shown in Figure 1 to Figure 2, a kind of color change head, comprises housing 1, with the controlling organization, interlinked mechanism and the actuating mechanism that are installed on described housing 1, described controlling organization comprises multiple color selection plates, and described color selection plate interval arranges, and described color selection plate comprises first connecting rod 21 and fork 23 separately;
One end of described fork 23 is used the first rotating shaft 6 to be installed on described housing 1, and the other end of described fork 23 can be freely swung, and the upper limb of described fork 23 is provided with depressible the first protuberance 231; Different described controlling organizations, described in it, the position of the first protuberance 231 is inconsistent;
The middle part of described first connecting rod 21 is used the second rotating shaft 7 to be installed on described housing 1, and the upper limb of its one end is provided with the second protuberance 211, and described the second protuberance 211 contacts at the lower edge of described fork 23; Also comprise the first elastic parts 3, act on described first connecting rod 21, give described the first protuberance 211 and contact at the resiliency of described fork 23 lower edges; Between different described controlling organizations, the position of described the second protuberance 211 is inconsistent, and when described the first protuberance 231 is during the closer to described the first rotating shaft 6, described the second protuberance 211 is more away from described the second rotating shaft 7.
While pressing described the first protuberance 231, described fork 23, to lower swing, is exerted pressure to described the second protuberance 211, and described first connecting rod 21 is rotated counterclockwise along the second rotating shaft 7.Described fork 23 links with described first connecting rod 21, swing the problem of offsetting pivot angle and stroke simultaneously, so described the first protuberance 231 is in the optional position of described fork 23 upper limbs, can be by adjusting the position of described the second protuberance 211 on described the first fork 21, thereby pressing described the first protuberance 231 makes it move the same stroke, and the rotational angle of described first connecting rod 21 is consistent, reach the object of selecting colour balance.By such design, while pressing different described the first protuberances 231, although its position is inconsistent, mobile the same stroke can trigger needle selection action.Between described the first elasticity group 3 for, when finishing while pressing described the first protuberance 231, drive described first connecting rod 21 and described fork 23 returns.
As shown in Figure 1 to Figure 2, the other end of described first connecting rod 21 is provided with hook portion 212, and described hook portion 212 the same sides and the position relative with described hook portion 212 are provided with retainer 213; Described control structure also comprises second connecting rod 22, the middle part of described second connecting rod 22 is used the 3rd rotating shaft 8 to be installed on described housing 1, its one end is provided with nose bar 221, slide between described hook portion 212 and retainer 213, described hook portion 212 and retainer 213 restrict the pendulum angle of described second connecting rod 22; Also comprise the second elastic parts 4, act on described second connecting rod 21, give described nose bar 221 and contact at the resiliency of described retainer 213; Described second connecting rod 22 is also provided with top supporting part 222.
In the time that described first connecting rod 21 rotates counterclockwise, described the second elastomeric element 3 promotes described second connecting rod 22 and rotates counterclockwise, and now described nose bar 221 slides into a side of described retainer 213; In the time of described first connecting rod 21 return, described first connecting rod 21 drives described first connecting rod 22 to overcome the elastic force of described the second elastomeric element 3, thereby gets back to initial position.The transformation of described second connecting rod 22 these two positions, promotes described interlinked mechanism, makes described actuating mechanism complete the action of needle selection.Described nose bar 221 is limited by described hook portion 212 and described retainer 213, and the hunting range of described second connecting rod 22 is limited, and prevents that the hunting range of described second connecting rod 22 is excessive, and part of damage, can bullet fast.
As shown in Figure 1 to Figure 3, also comprise slide cam selector, be installed on described housing 1, comprise body 51 and multiple needle selecting foot 52; Described needle selecting foot 52 is " T " font, and its top, through described body 51, is arranged in same level, and its bottom is the rectangular end of " T " font, contacts at respectively described the first protuberance 211.
The structure that described slide cam selector is such, allows the triggering part of described needle selecting foot 52 in same level, is more beneficial to the cooperation between part.
As shown in Figure 1 to Figure 2, described the first elastic parts 3 acts on the lower edge of described first connecting rod 21, and described the first elastic parts 3 is arranged in described first connecting rod 21 and is provided with one end of described the second protuberance 211.
As shown in Figure 1 to Figure 2, described the second elastic parts 4 is positioned at the other end relative with described nose bar 221, contacts in the left border of described second connecting rod 22.
As shown in Figure 1, between different described controlling organizations, the distance between described the first protuberance 231 and described the first rotating shaft 6, also has the distance between described the second protuberance 211 and described the second rotating shaft 7, is to be all successional variation.
As shown in Figure 1 to Figure 2, in described first connecting rod 21, between described hook portion 212 and retainer 213, region is smooth continuous circular arc, makes the frictional force of the slip of described nose bar 221 between described hook portion 212 and described retainer 213 less.
As shown in Figure 1 to Figure 2, preferred, described the first elastic parts 3 and the second elastic parts 4 are spring.
Or described the first elastic parts 3 and the second elastic parts 4 are shell fragment or rubber, do not provide this structure in accompanying drawing.
As shown in Figure 1 to Figure 2, the other end that described first connecting rod 21 is relative with described the first rotating shaft 6 is provided with limiting structure, comprises breach and the projection fixing and described housing 1 of described first connecting rod 21.
The present invention adopts said structure, use the problem in fork and between pivot angle and the first protuberance stroke of first connecting rod, make pressing stroke and can triggering needle selection action when consistent of each the first protuberance, select colour balance, and the action dexterity of pressing the first protuberance, resilience is fast, long service life, and it is simple in structure.
Finally should be noted that; above embodiment is only for illustrating technical scheme of the present invention but not limiting the scope of the invention; although the present invention is explained in detail with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement technical scheme of the present invention, and not depart from essence and the scope of technical solution of the present invention.
