In addition, if below in the described different embodiment of the utility model involved technical characteristic do not form conflict each other and just can be combined with each other.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of position-limit mechanism of the present utility model, comprise fixture 1, be arranged on the movement parts 2 on fixture 1 movingly, and elastic spacing assembly, wherein elastic spacing assembly comprises elastic spacing structure and coordinates position limiting structure, the two is separately positioned on fixture 1 with in movement parts 2, and when movement parts 2 moves to elastic spacing structure with the binding site coordinating position limiting structure to be combined, elastic spacing structure is combined with cooperation position limiting structure under the effect of its own resilient carries out spacing to movement parts 2; When movement parts 2 force under the effect being enough to the external force overcoming elastic spacing structure its own resilient elastic spacing structure with coordinate position limiting structure depart from conjunction with time, that removes movement parts 2 is spacing.
Such scheme is core scheme of the present utility model, because the elastic spacing structure be arranged between fixture 1 with movement parts 2 leans on the elastic force of self to realize and the combination coordinating position limiting structure, also be that the outer elastic force taking elastic spacing structure self of making every effort to overcome departs from and the combination coordinating position limiting structure simultaneously, therefore, not only operating handle is good, and sound is melodious when reaching the limit of position, and have prompt facility, the more important thing is elastic spacing structure with coordinate position limiting structure to depart to combine after can remove the spacing of movement parts 2, thus make movement parts 2 can walk around binding site to move forward.
With the use of elastic spacing structure and coordinate the structure of position limiting structure to have multiple, in the present embodiment, preferred elastomeric position limiting structure comprises the mounting hole 3 be molded on fixture 1, be arranged on the thimble 8 in mounting hole 3, and the bias piece be arranged between mounting hole 3 and thimble 8, the acting force of bias piece acts on thimble 8, has the trend making thimble 8 stretch out mounting hole 3; Position limiting structure is coordinated to comprise the spacing hole 4 be molded in movement parts 2, and the shape of the head of described thimble 8 meets: the head of described thimble 8 is applicable to inserting in described spacing hole 4, and when described movement parts 2 is subject under the effect of the external force being enough to the elastic force overcoming described bias piece, the described head of described thimble 8 is applicable to deviating from described spacing hole 4.Said structure is very simple, and low cost of manufacture, when reaching restraining position, spacing sound is little.Certainly, in other embodiments, also can be arranged on movable part 2 for mounting hole 3, thimble, bias piece, spacing hole 4 is arranged on fixture 1.Further, preferred bias piece is the spring 5 of the bottom in connection hole, one end 3, other end connecting ejector pin 8.
Further, the head of thimble 8 is preferably moulded as semisphere, and when can not only ensure that thimble enters spacing hole 4 like this, feel is clear, and sound is melodious, and can be convenient to thimble 8 when stressed, can deviate from spacing hole 4.But in actual design, the hemispherical nose of thimble 8 with spacing hole 4, coordinating of spring need through strict checking.
As shown in Figures 3 and 4, in the present embodiment, preferred fixture 1 is annular base body, movement parts 2 is annular element, one end end face of annular base body forms annular deep gouge 6, annular deep gouge 6 is applicable to annular element and inserts and rotate wherein, and the bottom land of annular deep gouge 6 is provided with elastic spacing structure or coordinates position limiting structure, and the end face of one end of the annular slot of applicable insertion of annular element is provided with and coordinates position limiting structure or elastic spacing structure.The setting of annular deep gouge 6 can guarantee that movement parts 2 stably rotates on fixture 1 by rotational trajectory smoothly, certainly, position-limit mechanism of the present utility model is not limited to the spacing of the movement parts 2 rotated, and can also be applicable to make parallel sliding, spacing in the movement parts such as curvilinear motion 2, application widely, due to this several forms of motion spacing in, the structure of elastic spacing assembly is the same, and just movement parts 2 is different with the version of fixture 1, therefore, much more no longer to chat.
Further, one end end face that movement parts 2 inserts deep gouge is provided with the chute 7 of the sinking of annular, and spacing hole 4 is molded over chute 7 end.The setting of chute 7 can be led to thimble 8, more steady when moving with movement parts 2 to make thimble 8.
Coordinate position limiting structure to be provided with multiple, be evenly distributed in movement parts 2, elastic spacing structure is provided with one, is arranged on fixture 1.Certainly, also can be that multiple cooperation position limiting structure is evenly distributed on fixture 1, an elastic spacing structure vibrational power flow be in movement parts 2.Like this, in the process can moved in movement parts 2, it is spacing to carry out many places, thus it is spacing to realize many gears.Coordinate the number of position limiting structure to arrange as required, as shown in Figure 1, coordinate position limiting structure (i.e. spacing hole 4) to be provided with four, elastic spacing structure is provided with 1.
The course of work of position-limit mechanism of the present utility model:
Now rotate for movement parts 2 opposed fixed member 1 and be introduced:
Rotating motion part 2, when movement parts 2 move to thimble 8 on fixture 1 with in movement parts 2 wherein a spacing hole 4 aligns time, under the effect of the spring 5 of pressurized, thimble 8 ejects mounting hole 3, is inserted in spacing hole 4, thus carries out spacing to movement parts 2.
When needs are removed spacing, firmly rotating motion part 2, the extruding being subject to movement parts 2 due to thimble 8 retreats in mounting hole 3, and spring 5 is shunk until thimble 8 exits in the spacing hole 4 of movement parts 2 completely, now namely movement parts 2 can rotate.
When thimble 8 is along chute 7 relative motion to next spacing hole 4, thimble 8 can slide in spacing hole 4 under spring force again, and play position-limiting action, can send clear and melodious sound, feel is clear simultaneously.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
