Description
Technical field
The present invention relates to a kind of travel(l)ing rest, particularly relate to a kind of travel(l)ing rest of deciding angle that its rotating maximum angle is restricted when rotating.
Background technique
A certain parts are rotated around an axle center, often adopt bearing structure to realize above-mentioned purpose in practice, but because bearing generally all moves in a circle when operation, can not be limited its rotating angle, therefore, at some in particular cases, during as above-mentioned need the restriction, just need to adopt in addition other supplementary structure to realize to the rotating maximum angle of parts.After adopting above-mentioned supplementary structure, the new problem that is occurred is that it has not only increased manufacture cost, and makes mechanical structure complicated more, has increased the probability that there was a mechanical failure.
In sum, at present problem demanding prompt solution is, needs a kind of maximum angle that a certain parts rotate that promptly can limit, and structure is unusual simple slewing gear again.
Summary of the invention
Technical problem to be solved by this invention is, a kind of travel(l)ing rest of deciding angle is provided, it adopts a kind of very simple rotational structure design, promptly can realize the rotating function of travel(l)ing rest, can reach the effect that the rotating maximum angle of travel(l)ing rest is limited again.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of travel(l)ing rest of deciding angle, this travel(l)ing rest comprises: a travel(l)ing rest, in addition, also comprise: two axle center holes, two axle center supports and two axle center, wherein, described two axle center holes lay respectively at the two ends of described travel(l)ing rest, described two axle center are individually fixed on described two axle center supports, described two axle center lay respectively in described two axle center holes, and described two axle center can be rotated in described two axle center holes respectively but its rotating maximum angle is subjected to the restriction of described two axle center holes.
In the described travel(l)ing rest of deciding angle, the open end in described axle center is provided with nut and breaks away from described axle center hole to prevent described axle center when rotating.
In the described travel(l)ing rest of deciding angle, the shape of described two axle center hole cross sections, size and angle are in full accord.
In the described travel(l)ing rest of deciding angle, the shape of described two axle center cross sections, size and angle are in full accord.
When the described travel(l)ing rest of deciding angle was vertical placement, shape had a certain degree between the cross section of described two axle center holes and the horizontal line.
Advantage of the present invention is, two axle center holes, two axle center supports and two axle center have been adopted in the disclosed travel(l)ing rest of deciding angle, wherein, design especially by shape and structure, make described two axle center in two axle center holes, to do conditional rotation respectively described two axle center and two axle center holes.In sum, the present invention has only carried out special design to the shape of two axle center and two axle center holes and structure and has just realized making travel(l)ing rest to carry out the purpose of conditional rotation, its structure is very simple, has dwindled the shared space of this travel(l)ing rest when having saved cost of production significantly greatly.

Embodiment
For further disclosing technological scheme of the present invention, be described with reference to the accompanying drawings embodiments of the present invention now.
Fig. 1 decides the overall structure schematic representation of the travel(l)ing rest of angle for the present invention; Fig. 2 decides the partial structurtes schematic representation of the travel(l)ing rest of angle for the present invention, the side structure when it shows axle center of the present invention and is arranged in axle center hole; Fig. 3 decides the structural representation of axle center hole of the travel(l)ing rest of angle for the present invention; Structural representation when the axle center that Fig. 4 decides the travel(l)ing rest of angle for the present invention is arranged in axle center hole, the Facad structure when it shows axle center of the present invention and is arranged in axle center hole.
Below in conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4 illustrate that the present invention decides the structure of travel(l)ing rest of angle and the annexation between the each several part, the present invention includes: a travel(l)ing rest 10, in addition, also comprise: two axle center holes 11, two axle center supports 20 and two axle center 21, wherein, described two axle center holes 11 lay respectively at the two ends of described travel(l)ing rest 10, described two axle center 21 are individually fixed on described two axle center supports 20, described two axle center 21 lay respectively in described two axle center holes 11, described two axle center 21 can be rotated in described two axle center holes 11 respectively, as shown in Figure 3 and Figure 4, being shaped as of described two axle center 21 and described two axle center holes 11 is non-circular, described two axle center 21 are being rotated behind the several angle and can blocked and can not be rotated further again by the outstanding structure on described two axle center holes 11, thereby the maximum angle of described two axle center 21 when rotating is subjected to the restriction of described two axle center holes 11.Further, the open end in described axle center 21 is provided with nut 22 to prevent that described axle center 21 breaks away from described axle center hole 11 and plays the effect that limits the relative displacement between described axle center 20 and the described axle center hole 11 when rotating.At last, shape, size and the angle of the cross section in described two axle center holes 11 and two axle center 21 are in full accord, can guarantee that like this maximum angle that described two axle center 21 can be rotated in described two axle center holes 11 is consistent.
In addition, as shown in Figure 3, when travel(l)ing rest of the present invention was vertical placement, shape had a certain degree between the cross section of described two axle center holes 11 and the horizontal line, made described two axle center 21 be kept off shape when rotating to the utmost point extreme position in described two axle center holes 11 and had a certain degree.
Decide the action situation of travel(l)ing rest when real work of angle below in conjunction with description of drawings the present invention.
In the real work when rotating travel(l)ing rest 10, cause described two axle center 21 in described two axle center holes 11, to be rotated respectively, when described two axle center 21 turn to as shown in Figure 4 state, described two axle center 21 are blocked and can not be rotated further again by the outstanding structure on described two axle center holes 11, at this moment, described two axle center 21 can only be rotated round about.Equally, also can be blocked and to be rotated further again in described two axle center 21, back that turn an angle round about by the outstanding structure on described two axle center holes 11.In a word, during real work, the maximum angle that described two axle center 21 can be rotated in described two axle center holes 11 is fixed.
More than, the basic ideas and basic principles of the present invention have been set forth by description of listed embodiment.But the present invention never is limited to above-mentioned listed mode of execution, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on technological scheme of the present invention of change all should belong to protection scope of the present invention.
