Abstract

A rail device comprises a rail body and multiple bushes; the rail body is formed by integrally extruding an aluminum material; a support part and a transmission board are respectively formed at upper and lower sides of the rail body; the transmission board is provided with multiple transmission holes in a penetrating mode; each bush is provided with an annular part and a stop part formed by convexly extending the side surface of the annular part; the annular parts of the bushes are sleeved in transmission holes of the rail body and form an embedding state, and the material hardness of the bushes is larger than that of the rail body. When a preset driving fluted disc relatively moves on the rail body, the transmission holes of the rail body are not abraded as the driving fluted disc is meshed with the bushes with stronger material hardness, so the use durability of the rail device is improved.

Description

Rail set

Technical field

A kind of track structure, is espespecially applicable to the companion ladder track at residence stairs place, is in particular the track structure that increases track structure bulk strength.

Background technology

The chair lift that tradition is installed in stair side is to utilize existing guide rail to be used as the drive mechanism of chair lift.And existing drive mechanism is for utilizing two guide rails that be arranged in parallel that support and the transmission agency of traditional chair lift are provided, but bulky and not attractive in appearance, therefore contriver of the present utility model develops one " rail type conveyer " then, in order to the drive mechanism of the traditional chair lift of further simplification, and the existing track groups of aforementioned in order to make " rail type conveyer " can one extrusion molding mode make, must make with aluminium material.In the time of traditional chair lift transmission, rely on existing fluted disc to be meshed to reach transmission effect with the driving hole of existing track groups, but because of the material hardness of existing track groups a little less than, make existing driving hole be very easy to be subject to existing fluted disc effect and produce wearing and tearing, causing the not durable use of existing set of rails.

Utility model content

The purpose of this utility model is, while allowing the transmission displacement in orbit of transmission fluted disc, and the driving hole of track below that can not wear and tear, and then increase the use durability degree of whole group of track.

For reaching above-mentioned purpose, the utility model provides a kind of rail set, comprises:

One track body, is made with one extrusion molding with aluminium material, and these upper and lower both sides of track body are formed with respectively support portion and driver plate, and driver plate is equipped with multiple driving holes;

Multiple linings, each lining has ring part, and the stopper section being protruded out by ring part side surface, and lining is provided with many fins in ring part outer peripheral edges, make the ring part of lining be sheathed on the driving hole of track body, many fins are embedded in the hole wall of driving hole, and to increase the anchoring strength of lining and track body, and the material hardness of lining is greater than the material hardness of track body.

Rely on above-mentioned technological means, can allow and drive fluted disc in the time of track body side relative displacement, because the default tooth portion lining stronger with material hardness that drives fluted disc engages, thus the driving hole of track body that can not wear and tear, and then promote use durability degree of the present utility model.

The specific embodiment

Refer to shown in Fig. 1 to Fig. 4, by knowing and find out in figure, rail set of the present utility model comprises track body 1 and multiple lining 2, wherein:

This track body 1 is made with one extrusion molding with aluminium material.Track body is formed with respectively support portion 11 and driver plate 12 in both sides Shang Xia 1, and driver plate 12 is equipped with multiple driving holes 13.The support portion 11 of the present embodiment middle orbit body 1 can be polygon or difform column.

Each lining 2 has ring part 21, and the stopper section 22 being protruded out by ring part 21 side surfaces, and makes to be formed with driving hole 211 in the ring part 21 of lining 2, and lining 2 is positioned at ring part 21 outer peripheral edges and is provided with many fins 23.The material hardness of each lining 2 of the present utility model is greater than the material hardness of track body 1.

Rely on above-mentioned, when multiple linings 2 and track body 1 in conjunction with time, be by corresponding each lining 2 and be sheathed in each driving hole 13 of track body 1, and the fin 23 of each lining 2 is embedded in the hole wall of driving hole 13, to increase the anchoring strength of lining 2 and track body 1.Make again stopper section 22 backstops of each lining 2 in driving hole 13 peripheries of track body 1, to allow multiple linings 2 complete assembling with track body 1.

Referring to shown in Fig. 4 and Fig. 5, is expression use view of the present utility model in figure.When use, driver plate 12 1 sides of track body 1 are provided with and drive fluted disc 3, and the driving fluted disc 3 of the present embodiment is arranged at chair lift (not shown) below, in order to drive chair lift transfer.Drive fluted disc 3 to there is tooth portion 31, when driving fluted disc 3 while rotating, be rely on drive the tooth portion 31 of fluted disc 3 and the driving hole 211 of each lining 2 be meshed reach.Feature of the present utility model is, utilize the material hardness of each lining 2 to be greater than the material hardness of track body 1, and then make to drive fluted disc 3 on the driver plate 12 of track body 1 when relative displacement, the application force that drives the tooth portion 31 of fluted disc 3 to produce directly acts on each lining 2, each lining 2 can be absorbed this stress and not produce deformation, and then avoid driving hole 13 surfaces of track body 1 to produce abrasion, therefore can allow the utility model can significantly increase in the use use durability degree.

Claims

1. a rail set, is characterized in that, comprises:

Multiple linings, each lining has ring part, and the stopper section being protruded out by ring part side surface, and lining is provided with many fins in ring part outer peripheral edges, make the ring part of lining be sheathed on the driving hole of track body, many fins are embedded in the hole wall of driving hole, and the material hardness of lining is greater than the material hardness of track body.
