Description
Technical field
The invention belongs to a kind of railing apparatus field, be specifically related to one and turn over and put railing.
Background technology
Found with careful market survey widely by long-term, no matter be that external movable stand produces esbablished corporation, or domestic stadiums enterprise, the lateral rail of its movable stand produced 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 needs to disassemble from movable stand, installs again during use, so operation bothers very much; As long as flexible lateral rail then can realize realizing movable stand folding and unfolding when not dismounting railing by flexible, but flexible lateral rail complex structure, and also shaft is arranged to multi-section type structure, and intensity reduces.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention will solve in prior art to plug the lateral rail problem that dismounting bothers and lateral rail shaft intensity of stretching is low 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: one is turned over and put railing, is 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 and railing to be all arranged on railing pin and to be 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 to railing all the time, the left end of described eccentric top block and railing pin sidewall contact, right-hand member contacts by rotating to coordinate with railing or is separated; The axial end of described rotating shaft is provided with a keyhole controlling rotating shaft and rotate.
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.
Be provided with latch between described eccentric top block and rotating shaft, and be fixedly linked by latch.
The shape of described keyhole is 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 puts railing, by being rotatably connected with the railing pin of movable stand by railing, making to turn over and putting railing and can dig or keep flat, and when movable stand is carried then without the need to dismounting, avoids the step of dismounting, uses convenient.Reach above-mentioned effect, therefore railing does not need to be designed to multi-section type structure yet, thus makes to turn over that to put rail structure simple, and intensity is high.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
One is as shown in Figure 1, Figure 2 and Figure 3 turned over and is put railing, is 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 and railing 1 to be all arranged on railing pin 4 and to be 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 be provided with latch between eccentric top block 2 and rotating shaft 3, and be fixedly connected with by latch, this eccentric top block 2 makes eccentric top block 2 rotate to railing 1 all the time by torsion spring 5, the left end of described eccentric top block 2 and railing pin 4 sidewall contact, right-hand member contacts by rotating to coordinate with railing 1 or is separated; The left side of railing 1 also can be withstood after the right-hand member of eccentric top block 2 contacts with railing 1, thus the anglec of rotation of non-floating rail 1, during separation, then railing can rotate freely.The axial end of described rotating shaft 3 is provided with a keyhole 6 controlling rotating shaft 3 and rotate, and the shape of described keyhole 6 is triangle, thus is inserted in keyhole 6 by design trigonocephalic key or spanner, controls rotating shaft 3 and drives eccentric top block 2 to rotate.
As shown in Figure 4, described eccentric top block 2 contains circular arc 7 and the first tangent inclined-plane 8 with the bread of railing pin 4 sidewall contact; Described circular arc 7 is arranged on the bottom on the first inclined-plane 8.Eccentric top block 2 can be made freely to be rotated down by arranging circular arc in bottom.The angle rotated is greater than more than 90 °, eccentric top block 2 can be made to limit the angle rotated up, can only rotate 1 ° by arranging the first inclined-plane 8 on top.Described eccentric top block 2 and the face of railing 1 sidewall contact are the inclined-plane that the second inclined-plane 9, inclined-plane 9, second is designed to assembly from bottom to top and is tilted to the right, and when the second inclined-plane 9 contacts with railing 1, can be rotated down, can not be stuck.
As depicted in figs. 1 and 2 when of the present invention turn over put railing need to dig use time, first railing 1 is rotated up, simultaneously, the bottom surface of described railing 1 and the contact of incline plane at eccentric top block 2 top, and drive eccentric top block 2 to be rotated down, when railing 1 rotate up 90 ° on earth after, the bottom surface of described railing 1 and the inclined-plane at eccentric top block 2 top depart from, described eccentric top block 2 rotates up automatically by under torsion spring 5 reset response, the second inclined-plane is made to withstand the side of railing 1, thus fix the anglec of rotation of its railing 1, railing 1 is normally used.When turn over put railing need to keep flat downwards time, being inserted into control rotating shaft 3 in leg-of-mutton keyhole 6 by key or spanner drives eccentric top block 2 to be rotated down, and makes the second inclined-plane 9 depart from the side of railing 1, makes railing not have bar, thus by after railing 1 half-twist, can keep flat before the lights.By railing 1 is rotatably connected with the railing pin 4 of movable stand, makes to turn over and put railing 1 and can dig or keep flat, when movable stand is carried then without the need to dismounting, avoid the step of dismounting, use convenient.Because reaching above-mentioned effect, therefore railing 1 does not need to be designed to multi-section type structure yet, thus makes to turn over that to put rail structure simple, and 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, under the prerequisite not departing from 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.
