further, the one end on slip deck inserts fixing deck slidably, and the other end is connected with the bottom of the second montant.
further, deck is fixedly connected with sleeve in slip, and this sleeve can be inserted up or down in the bottom of the second montant, and spring is arranged in sleeve.
further, deck is connected with fixed pulley in slip, this fixed pulley is in immediately below the second montant, the other end of stay cord is connected by the top of this fixed pulley and spring or above-mentioned parts, thus one section that is connected with the top of spring or above-mentioned parts that makes stay cord in vertically arranging, so that stay cord applies power to spring.
further, be provided with a cover plate between the bottom of the second montant and spring, the other end of stay cord is connected on this cover plate, and when stay cord pulls cover plate, cover plate applies downward power to spring and makes spring-compressed.
further, the first cross bar inside is provided with interior pulley, the second cross bar has the gathering sill matched with interior pulley.
further, the other end of the first cross bar is closed, and the inside of this other end is provided with a spring, when one end of the second cross bar moves to the other end of the first cross bar, one end of second cross bar makes a spring-compressed, thus provide enough thrust for stretching out of the second cross bar next time, the second cross bar is stretched out more smoothly.
further, the second cross bar is equal with the first cross bar quantity, and plugs accordingly.
further, be removably connected by steady pin between the second cross bar with the second montant.
owing to have employed technique scheme, the utility model is used for the scalable railing of sliding platform, the deformation problems of movable railing units is efficiently solved by anti-deformation mechanism, avoid the stuck phenomenon of movable railing units in telescopic process, and according to the distance of stretch out and draw back of movable railing units, corresponding bit shift compensation can occur.This is used for that scalable rail structure of sliding platform is simple, cost is low, adaptivity is strong, is convenient to remove and install.

Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, can be easier to be readily appreciated by one skilled in the art to make advantage of the present utility model and feature.
as can be seen from the structural representation of accompanying drawing 1 to accompanying drawing 3, the utility model provides a kind of scalable railing for sliding platform, it comprises the non-floating rail 1 be connected with at least one first montant 12 by least one first cross bar 11, movable railing units 2, second cross bar 21 be connected with at least one second montant 22 by least one second cross bar 21 inserts wherein from one end telescopically of the first cross bar 11.Particularly, the second cross bar 21 is equal with the first cross bar 11 quantity, and plugs accordingly.In the present embodiment, the first cross bar 11 and the second cross bar 21 are two, and the first montant 12 is two, and the second montant 22 is one, and the other end that insertion first cross bar 11 one end being connected to the second cross bar 21 is contrary.Removably be connected by steady pin 24 between second cross bar 21 with the second montant 22.
in order to improve the stability of movement between the first cross bar 11 and the second cross bar 21 further, the first cross bar 11 inside is provided with on interior pulley 13, second cross bar 21 has the gathering sill 23 matched with interior pulley 13.Particularly, interior pulley 13 is respectively provided with a row up and down the first cross bar 11 inwall, and similarly, gathering sill 23 is respectively provided with one up and down the second cross bar 21 outer wall.
sliding platform comprise be fixedly connected with the bottom of the first montant 12 fixing deck 3, to be slidably connected mutually with fixing deck 3 and the slip deck 4 that can be connected up or down with the bottom of the second montant 22.Particularly, the one end on slip deck 4 inserts fixing deck 3 slidably, and the other end is connected with the bottom of the second montant 22.
above-mentioned scalable railing also comprises anti-deformation mechanism, and this anti-deformation mechanism comprises the spring 5 between bottom and slip deck 4, one end of being arranged on the second montant 22 and to be fixed on fixing deck 3 other end directly or to apply downward power by the top of parts to spring 5 be stay cord 6, the counterweight 7 hung on stay cord 6 that spring 5 compresses.
in one more preferably embodiment, slip deck 4 is connected with fixed pulley 8, this fixed pulley 8 is in the positive lower end of the second montant 22, the other end of stay cord 6 is connected by the top of this fixed pulley 8 and spring 5 or parts, thus one section that is connected with the top of spring or above-mentioned parts that makes stay cord in vertically arranging, so that stay cord applies power to spring.
more preferably, slip deck 4 is fixedly connected with sleeve 41, the bottom of the second montant 22 can insert this sleeve 41 up or down, and spring 5 is arranged in sleeve 41.A cover plate 9 is provided with between the bottom of the second montant 22 and spring 5, the other end of stay cord 6 is connected on this cover plate 9, when stay cord pulls cover plate, cover plate applies downward power to spring and makes spring-compressed, so more be beneficial to the connection of the other end of stay cord 6, and be beneficial to the power that spring 5 applies upwards to the second montant 22.
in one more preferably embodiment, the other end of the first cross bar 11 is closed by an end cap 15, and the inside of this other end is provided with a spring 14, when one end of the second cross bar 21 moves to the other end of the first cross bar 11, one end of second cross bar 21 makes a spring 14 compress, thus provide enough thrust for stretching out of the second cross bar next time, the second cross bar is stretched out more smoothly.
this principle being used for the scalable railing of sliding platform is as follows:
drive movable railing units 2 protruding when outwards sliding in slip deck 4, this stretches out in process, stay cord 6 is tightened up, in-line is leveled off to gradually from V-arrangement, thus the downward power that stay cord 6 pairs of springs 5 apply reduces gradually, spring 5 resets gradually along with stretching out of movable railing units 2 and upwards jack-up second montant 22, and then avoids the deformation of the second cross bar 21, thus counteracts slip deck 4 deformation that downward-sloping drive railing produces when outwards sliding.On the contrary, when retracting, because the effect stay cord 6 of counterweight 7 replys V-arrangement gradually, stay cord 6 pairs of spring 5 applied forces become ambassador's spring 5 and gradually reduce, and the second montant 22 recovers gradually with the spacing on slip deck 4.
this is used for the scalable railing of sliding platform, is efficiently solved the deformation problems of movable railing units, avoids the stuck phenomenon of movable railing units in telescopic process, and according to the distance of stretch out and draw back of movable railing units, corresponding bit shift compensation can occur by anti-deformation mechanism.This is used for that scalable rail structure of sliding platform is simple, cost is low, adaptivity is strong, is convenient to remove and install.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
