Description
Technical field
The invention belongs to a kind of railing apparatus field, be specifically related to a kind of turning over and put railing.
Background technology
By long-term, find with careful market survey widely, no matter be that external movable stand is produced esbablished corporation, or domestic stadiums enterprise, the lateral rail of the movable stand of its production can be divided into two kinds of forms: a kind of is plug lateral rail, and another kind of is flexible lateral rail.Movable stand needs folding and unfolding when not using, and plug lateral rail need to disassemble from movable stand, installs again, so operation bothers very much during use; Flexible lateral rail needs only can realize by stretching realizes movable stand folding and unfolding in the situation that of not dismounting railing, but flexible lateral rail complex structure, and also shaft is arranged to multi-section type structure, strength decreased.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is will solve to have now in technology, to plug lateral rail dismounting trouble and the low problem of lateral rail shaft intensity of stretching when movable stand keeps flat and use.
(2) technical scheme
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of turning over put railing, be arranged on the railing pin of movable stand, described in turn over and put railing and comprise railing, eccentric top block, torsion spring and rotating shaft; Described rotating shaft is all arranged on railing pin and with railing pin and is rotatably connected with railing pin, described eccentric top block and torsion spring set are connected in rotating shaft, wherein eccentric top block is fixedly connected with rotating shaft and by torsion spring, eccentric top block is rotated all the time to railing, the left end of described eccentric top block and railing pin sidewall contact, right-hand member coordinates contact or separated by rotation with railing; The axial end of described rotating shaft is provided with a keyhole of controlling rotating shaft rotation.
The bread of described eccentric top block and railing pin sidewall contact contains circular arc and the first tangent inclined-plane; Described circular arc is arranged on the bottom on the first inclined-plane.
The face of described eccentric top block and railing sidewall contact is the second inclined-plane.
Between described eccentric top block and rotating shaft, be provided with latch, and be fixedly linked by latch.
Described keyhole be shaped as triangle.
The arranged outside of described rotating shaft has a jump ring, and described rotating shaft is rotatably connected by jump ring with railing pin.
(3) beneficial effect
Of the present invention turning over put railing, by railing is rotatably connected with the railing pin of movable stand, makes to turn over and puts railing and can dig or keep flat, and when movable stand is carried, without dismounting, avoided the step of dismounting, uses convenient.Reached above-mentioned effect, thus railing do not need be yet designed to multi-section type structure, thereby make to turn over, to put rail structure simple, intensity is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of putting after railing is upwards dug that turns over of the present invention;
Fig. 2 is the structural representation of putting after railing keeps flat downwards that turns over of the present invention;
Fig. 3 is the sectional view of A-A in Fig. 2;
Fig. 4 is the plan view of eccentric top block of the present invention;
In figure, 1 is that railing, 2 is that eccentric top block, 3 is that rotating shaft, 4 is that railing pin, 5 is that torsion spring, 6 is that keyhole, 7 is that circular arc, 8 is that the first inclined-plane, 9 is that the second inclined-plane, 10 is that latch, 11 is jump ring.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
A kind of turning over as shown in Figure 1, Figure 2 and Figure 3 put railing, be arranged on the railing pin 4 of movable stand, described in turn over and put railing and comprise railing 1, eccentric top block 2, torsion spring 5 and rotating shaft 3; Described rotating shaft 3 is all arranged on railing pin 4 and with railing pin 4 and is rotatably connected with railing pin 4, and the arranged outside of described rotating shaft 3 has a jump ring 11, and described rotating shaft 3 is rotatably connected by jump ring with railing pin 4.Described eccentric top block 2 is socketed in rotating shaft 3 with torsion spring 5, wherein between eccentric top block 2 and rotating shaft 3, be provided with latch, and be fixedly connected with by latch, this eccentric top block 2 makes eccentric top block 2 all the time to railing 1 rotation by torsion spring 5, the left end of described eccentric top block 2 and railing pin 4 sidewall contacts, right-hand member coordinates contact or separated by rotation with railing 1; The left side that also can withstand railing 1 after the right-hand member of eccentric top block 2 contacts with railing 1, thereby the anglec of rotation of non-floating rail 1, when separated, railing can rotate freely.The axial end of described rotating shaft 3 is provided with a keyhole 6 of controlling rotating shaft 3 rotations, described keyhole 6 be shaped as triangle, thereby by designing a trigonocephalic key or spanner, be inserted in keyhole 6, control rotating shaft 3 and drive eccentric top blocks 2 rotations.
As shown in Figure 4, the bread of described eccentric top block 2 and railing pin 4 sidewall contacts contains circular arc 7 and the first tangent inclined-plane 8; Described circular arc 7 is arranged on the bottom on the first inclined-plane 8.By being set in bottom, circular arc can make eccentric top block 2 freely be rotated down.The angle of rotation is greater than more than 90 °, by the first inclined-plane 8 is set on top, can make eccentric top block 2 limit the angle rotating up, and can only rotate 1 °.Described eccentric top block 2 is that 9, the second inclined-planes 9, the second inclined-plane are designed to the inclined-plane that assembly is tilted to the right from bottom to top with the face of railing 1 sidewall contact, when the second inclined-plane 9 contacts with railing 1, can be rotated down, and can not be stuck.
As depicted in figs. 1 and 2 when of the present invention turning over put railing and need to be dug while using, first railing 1 is rotated up, simultaneously, the bottom surface of described railing 1 contacts with the inclined-plane at eccentric top block 2 tops, and drive eccentric top block 2 to be rotated down, when railing 1 rotate up 90 ° on earth after, the inclined-plane at the bottom surface of described railing 1 and eccentric top block 2 tops departs from, described eccentric top block 2 is subject to automatically to rotate up under torsion spring 4 reset responses, make the second inclined-plane withstand the side of railing 1, thereby fix the anglec of rotation of its railing 1, railing 1 is normally used.When turning over when putting railing and need to keep flat downwards, by key or spanner, be inserted into the interior control rotating shaft 3 of leg-of-mutton keyhole 6 and drive eccentric top block 2 to be rotated down, make the second inclined-plane 9 depart from the side of railing 1, make railing there is no bar, thereby can, by after railing 1 half-twist, keep flat before the lights.By railing 1 is rotatably connected with the railing pin 4 of movable stand, make to turn over and put railing 1 and can dig or keep flat, when carrying, movable stand without dismounting, avoided the step of dismounting, use convenient.Because having reached above-mentioned effect, thus railing 1 do not need be yet designed to multi-section type structure, thereby make to turn over, to put rail structure simple, intensity is high.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
