Description

A kind of adjustable for height scaffold

Technical field

The utility model is related to a kind of scaffold, more particularly to a kind of adjustable for height scaffold.

Background technology

Scaffold is to ensure workbench that each work progress is smoothed out and sets up.Position by setting up is divided into outer Scaffold, internal scaffolding；It can be divided into timber scaffolding, bamboo scaffolding, steel pipe scaffold by material difference；It is divided by structural form vertical Rod-type scaffold, bridge scaffold, swinging scaffold, suspended scaffold, choose formula scaffold, climb formula foot hand door-type scaffold Frame.

The support foot hight of existing scaffold is typically uncontrollable, but in practice of construction scene, ground often heap Many construction wastes or ground inherently injustice are accumulated, this can cause existing scaffold that can not smoothly be positioned over ground On, often there is one high and one low situation, make worker in operation process there are security risk, therefore have improved space.

Utility model content

The purpose of this utility model is to provide a kind of with adjustable for height scaffold.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of adjustable for height scaffold, including supporting rack and the backing plate being positioned on support frame as described above, the support Frame includes several legs, and each feet bottom is mounted on adjusting the adjusting part of support foot hight；The adjusting Component includes retainer ring, adjusting rod, several supporting rods, several motion bars, loose collar, spacing ring and handshake part, described Fixing shrink ring is fixed arranged on the feet bottom blending bolt, several described supporting rods are circumferentially articulated with outside retainer ring at equal intervals Side；The adjusting rod top is threadedly connected to foot bottom end face, and bottom is connected with handshake part, and loose collar is located at described hold Above hand and adjusting rod is movably set in, spacing ring is integrally connected to adjusting rod and above loose collar, makes the activity Ring can not be moved along adjusting rod length direction；The motion bar number is consistent with supporting rod number and one end is circumferential hinged at equal intervals In loose collar lateral surface, the other end is hingedly connected to the supporting rod side.

It using the above program, can be independent to leg by adjusting part if in the case that ground out-of-flatness occurs in when construction It adjusts.When needing to adjust, rotate the handshake part in adjusting part and loose collar is driven to move up and down, so that several supporting rods It outwards struts or inwardly closes up together, realize that height is adjusted by changing the angle between supporting rod and ground, make entire Scaffold can be put surely on the ground of out-of-flatness, improve security, and by setting multiple supporting rods and this multiple Strut contacts at ground, is compared to single leg and contacts at for ground more safety and stability.

Preferably, support plate, the support plate upper surface and support are both provided on the bottom face of each supporting rod Bar bottom is hinged.

Using the above program, the setting of support plate can increase the contact area between supporting rod and ground, enable scaffold It is enough more steady to be positioned on ground, by the way that support plate and supporting rod are hinged, make in supporting rod when extending out or closing up, support Plate bottom surface can be bonded with ground always.

Preferably, each support plate lower end is connected with to be inserted into boring with grabbing for ground.

Using the above program, if running into quality than relatively soft ground, ground can be inserted directly by entire foot hand by boring with grabbing Frame is fixed on ground, further improves security.

Preferably, described bore with grabbing is bolted to connection between support plate.

Using the above program, by grabbing bore and be arranged to be detachably connected with support plate, facilitate the ground according to differing texture It decides whether to bore with grabbing, is also convenient for carrying.

Preferably, it is provided with to place the holder bored with grabbing on support frame as described above.

Using the above program, holder is convenient to carry and remove together for storing boring with grabbing of disassembling and bolt Fortune.

Preferably, the leg side offers the mounting hole that several are in longitudinal arrangement, the retainer ring and the peace Dress hole is bolted to connection.

Using the above program, if the adjustable range of adjusting part is insufficient for actual demand, it is liftoff retainer ring can be changed The distance in face increases the adjustable range between leg and ground, makes adjusting more flexible and changeable to adapt to different surface states.

Preferably, the quantity of the supporting rod differs 120 degree for 3 and mutual angle.

Using the above program, by the way that the quantity of supporting rod is arranged to 3, will be adjusted by the principle of 3 point locations Component is fixed on ground, not only securely but also can save material.

Preferably, the handshake part is cylindrical and side is provided with non-slip texture.

Using the above program, by setting non-slip texture in handshake part side, when rotated, it is possible to increase hand and handshake part it Between frictional force, make rotation more efficiency.

In conclusion the utility model has the advantages that：

1. the height that can realize scaffold by setting adjusting part is adjusted, so as to which entire scaffold is steadily positioned over Uneven ground, improves security；

2. by opening up several on leg in the mounting hole of genesis analysis and retainer ring being made to pass through bolt with mounting hole It is fixedly connected, increases height adjustment range.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

A kind of adjustable for height scaffold disclosed in the present embodiment.

As shown in Figure 1, a kind of adjustable for height scaffold, including supporting rack 1 and the backing plate being positioned on supporting rack 12, Supporting rack 1 includes 4 legs 11, and each 11 bottom of leg is mounted on adjusting the adjusting part 3 of 11 height of leg.

As shown in Fig. 2, several peaces that adjusting part 3 is supplied to install longitudinally are offered on each 11 bottom outside face of leg Fill hole 111.

Adjusting part 3 includes retainer ring 31, adjusting rod 33,3 supporting rod 32,3 motion bar 37, loose collar 35, /V Ring 34 and handshake part 36, retainer ring 31 are sheathed on 11 bottom blending bolt of leg and are fixed on 11,3 supporting rods of leg 32 circumferentially 31 lateral surface of retainer ring is articulated at equal intervals.

33 top of adjusting rod is vertically threadedly connected to 11 bottom face of leg, and bottom is connected with handshake part 36, handshake part 36 is cylindrical and be provided with antiskid thread on its periphery.Loose collar 35 is movably set in adjusting rod 33 and positioned at handshake part 36 tops, spacing ring 34 are sheathed on adjusting rod 33 and positioned at 35 top of loose collar, spacing ring 34 and 33 integrally connecteds of adjusting rod, make Loose collar 35 can not be moved along 33 length direction of adjusting rod, can only be rotated in a circumferential direction.
