Abstract
The utility model discloses a kind of supports of stepless adjustment telescopic, including casing and the threaded rod being plugged in casing, described sleeve pipe and threaded rod are equipped with gib head in one end far from the two junction, two gib heads keep same level, adjusting nut is equipped in described sleeve pipe in an axial direction, the adjusting nut is screwed on threaded rod, and the position-limit mechanism for preventing the two relative rotation is additionally provided between described sleeve pipe and threaded rod.This flexible support can be by pulling force and pushing force, realize the function of traditional strut, in the case where realizing traditional strut basis, it can also realize the function of stepless adjusting length, cater to the requirement of different specification size, threaded rod is not rotated with nut and is rotated, and the gib head of casing and the gib head moment of threaded rod keep same level.
Description
Technical field
The utility model is related to the stent lifting devices of building trade more particularly to a kind of stepless adjustment telescopic to support.
Background technology
In building trade, although the specification of building of frame body has national Specification, but regulation only limits maximum ruler
It is very little, so the specification for having led to building is various, after frame body height is adjusted, since height dimension or gib head direction become
The reason of change, often will appear situation about can not be overlapped between column, be compelled against one's will, readjusts stem height, reversely lead in this way
Cause column that can not adjust most suitable position.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of stepless adjustment telescopic support, can
Step-less adjustment is realized to most suitable size, and ensures that both ends gib head is in same level always.
Technical solution is used by the utility model solves its technical problem：
A kind of stepless adjustment telescopic support, including casing and the threaded rod being plugged in casing, described sleeve pipe and threaded rod exist
One end far from the two junction is equipped with gib head, and two gib heads keep same levels, are equipped in an axial direction in described sleeve pipe
Adjusting nut, the adjusting nut are screwed on threaded rod, and being additionally provided between described sleeve pipe and threaded rod prevents the opposite rotation of the two
The position-limit mechanism turned.
As an improvement of the above technical solution, the position-limit mechanism include be opened in an axial direction the limiting slot on threaded rod with
And the spacer pin on casing, the spacer pin cooperation are inserted into limiting slot.
As an improvement of the above technical solution, the limiting slot extends radially through threaded rod, and the spacer pin extends transversely through
Sleeve side walls simultaneously pass through stop nut and are locked on casing.
As an improvement of the above technical solution, the adjusting nut outer wall is circumferentially arranged with bulge loop, outside described sleeve pipe side wall
Equipped with block board, the bulge loop is placed in block board.
As an improvement of the above technical solution, the block board is welded on sleeve side walls in an axial direction.
As an improvement of the above technical solution, it is symmetrical above and below to be distributed on sleeve side walls there are two the block board settings.
The beneficial effects of the utility model have：
This flexible support can be realized the function of traditional strut by pulling force and pushing force, realize traditional strut
Under basis, moreover it is possible to realize the function of stepless adjusting length, cater to the requirement of different specification size, threaded rod is not revolved with adjusting nut
Then rotation, the gib head of casing and the gib head moment of threaded rod keep same level.
Description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：
Fig. 1 is the structure diagram of the utility model embodiment；
Fig. 2 is the partial cutaway schematic of the utility model embodiment.
Specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of stepless adjustment telescopic support of the utility model including casing 1 and is plugged in casing 1
Threaded rod 2, described sleeve pipe 1 and threaded rod 2 far from both one end of junction be equipped with gib head 3, two gib heads 3 keep same
One horizontal plane is equipped with adjusting nut 4 in described sleeve pipe 1 in an axial direction, and the adjusting nut 4 is screwed on threaded rod 2, described sleeve pipe
Being additionally provided between 1 and threaded rod 2 prevents the position-limit mechanism 5 of the two relative rotation.
With further reference to Fig. 1, the position-limit mechanism 5 includes the limiting slot 51 being opened in an axial direction on threaded rod 2 and peace
Spacer pin 52 on casing 1, the cooperation of spacer pin 52 is inserted into limiting slot 51, in order to enhance the intensity of position-limiting action,
Wherein, the limiting slot 51 extends radially through threaded rod 2, and the spacer pin 52 extends transversely through 1 side wall of casing and passes through limiting spiral shell
Mother 53 is locked on casing 1, and the stroke of threaded rod 2 is consistent with the axial length of limiting slot 51.
In addition, 4 outer wall of adjusting nut, circumferentially arranged with bulge loop 6,1 side wall of described sleeve pipe is externally provided with block board 7, described
There are two the settings of block board 7, and symmetrical above and below to be distributed on 1 side wall of casing, the block board 7 is welded on 1 side wall of casing in an axial direction
On, the bulge loop 6 is placed in block board 7.
This flexible support is in collection, rotating adjusting nut 4 so that threaded rod 2 declines, and forms minimum collection size, works as receipts
During Tibetan, threaded rod 2 will not autorotation, therefore avoid in transit jolt so that threaded rod 2 rotate it is outer de-；During work, rotation
Turn adjusting nut 4 so that the distance of two gib heads 3 meets the size of installation needs, and threaded rod 2 is not rotated with adjusting nut 4 and revolved
Turn, the gib head of casing 1 keeps same level with the gib head moment of threaded rod 2, after the connection of two gib heads 3, connects due to the use of screw thread
It connects, and adjusting nut 4 can not be detached from casing 1, therefore this flexible support can be by pulling force, and can be passed by pressure realizing
Under the strut basis of system, moreover it is possible to realize the function of stepless adjusting length.
The better embodiment of the above, only the utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as it reaches the technique effect of the utility model with any same or similar means, should all belong to the utility model
Protection domain.
