Abstract

The utility model relates to a sheath device of a lifting ladder outer post. The disclosed sheath device forms a shape of a smooth arc-shaped body which is made of soft material and has the shape which is approximate to a horseshoe, and the corresponding points of two inner side walls are provided with inwards convex hooks. A partition board which is mutually partitioned with a main wall with certain distance is arranged on the inner bottom, and a transverse groove is formed between the partition board and the main wall. The utility model can prevent a metal lifting ladder from the accidental harm of a human body when used and has the advantages of safety, simple structure and convenient use.

Description

Lift column jacket sheath device

Technical field

The utility model relates to the ladder safety device.

Background technology

At present, the lift that people use or sold on market, great majority are made up of outer, interior flexible wire ladder frame, and in the end of wire ladder column jacket, because the unshielded lid of otch is usually cut hand in the use, this insecurity becomes the total defective of metal lift.

Summary of the invention

The purpose of this utility model provides a kind of lift column jacket sheath device, and the unexpected injury during this sheath device can prevent to use is safe and reliable, and simple structure is easy to use.

Technical solution of the present utility model is: the utility model lift column jacket sheath device is made the profile of the slick and sly approximate water chestnut in neighboring with flexible material, at its all oriented projecting inward hook in two inside walls corresponding position, dividing plate with main wall space certain distance was arranged on the interior end, form a translot between dividing plate and the main wall, two interior hooks by inner side slot position and dual-side setting interlock with the wallboard and two square holes of outer cleat stanchion end corresponding site, make sheath tightly overlap cleat stanchion end outside, can not get loose.

The above outside slick and sly approximate shape of a hoof inner with overlap outer cleat stanchion section bar cross section and profile adapts.

The hook to projecting inward of two inside walls described in the utility model is large and small, shape, position and the lock hole that overlapped on the cleat stanchion adapt.

Translot between above the utility model dividing plate and the main wall wide with overlap cleat stanchion section bar main wall thick degree and shape adapts.

The utility model has the advantages that owing to loaded onto sheath stretching to fall on the external post of terraced descending stair, can protect the user not hurt by metallic object, safe and reliable, simple structure, easy to use.

Description of drawings

Fig. 1 is an organigram of the present utility model;

Fig. 2 is a duty sectional structural map of the present utility model;

Fig. 3 is hook of the present utility model and cleat stanchion lock-out state schematic diagram;

Fig. 4 is a duty position view of the present utility model.

The specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, Fig. 4, the utility model lift column jacket column jacket sheath device is the slick and sly water chestnut profile that there is vertical wall the approximate neighboring of flexible material, at its all oriented projecting inward hook 1 in two inside walls corresponding position, dividing plate 2 with terraced column jacket sheath master wall space certain distance was arranged on the interior end, form a translot between dividing plate 2 and the main wall.

The approximate slick and sly water chestnut profile that there is a vertical wall the utility model neighboring is overlapped cleat stanchion section bar 3 profiles and is adapted with inboard., the shape 1 large and small to projecting inward hook of lift column jacket sheath device two inside walls, position and the lock hole that is overlapped on the cleat stanchion section bar 3 adapt, the translot between dividing plate and the main wall wide with overlap cleat stanchion section bar 3 main wall thick degree and adapt.

When the utility model used, being cleat stanchion 3 ends that sheath is inserted in descending stair buckled into lock hole on the descending stair column section 3 until the hook on two inside walls 1, simultaneously, cleat stanchion master wall top margin inserts in the interior elongate recesses of sheath, at two hooks, under the locking at groove three places, sheath just can not come out in slippage.

Claims

1, lift column jacket sheath device, it is characterized in that lift column jacket sheath device is the profile of the slick and sly approximate water chestnut of periphery of flexible material, at its all oriented projecting inward hook in two inside walls corresponding position, dividing plate with main wall space certain distance was arranged on the interior end, form a translot between dividing plate and the main wall.

2, lift column jacket sheath device according to claim 1 is characterized in that the neighboring for being horseshoe-shaped slick and sly arc body, inboard with overlap cleat stanchion section bar profile and adapt.

3, lift column jacket sheath device according to claim 1 is characterized in that the hook to projecting inward of two inside walls is large and small, shape, position and the lock hole that overlapped on the cleat stanchion adapt.

4, lift column jacket sheath device according to claim 1, it is characterized in that translot between dividing plate and the main wall wide with overlap cleat stanchion section bar main wall thick degree and shape adapts.
