Description

Flexible supporter

Technical field

The utility model relates to a kind of flexible supporter.

Background technique

In the existing technology, flexible supporter only uses single locking device to fix usually or loosens the slip of telescopic pipe in fixed tube, the state that flexible supporter can only be in clamped condition or loosen fully.Do not hold after the locking device of telescopic component all opens operator, telescopic pipe descends very easily rapidly, causes falling rapidly of the flexible supporter and the object of hanging, so that danger such as object smashes or personnel come to harm.

The model utility content

The purpose of the utility model is to provide a kind of flexible supporter that makes telescopic pipe ability slip when locking device is opened.

The purpose of the utility model realizes through following technological scheme: a kind of flexible supporter; Comprise telescopic pipe, accommodate the fixed tube of said telescopic pipe and the locking device that can fix said telescopic pipe; A friction ring is installed between said telescopic pipe and fixed tube; Said friction ring is socketed in the said telescopic pipe outside, and the outer side contacts of said friction ring and said telescopic pipe, is in damping state when said telescopic pipe is glided.

In the utility model, the two ends external diameter of said friction ring differs, and the less end of said friction ring bore and the outer side contacts of said telescopic pipe.

In the utility model, said friction ring is tapered, be preferably awl pawl type, and the tapering of friction ring is towards the below.

In the utility model; The inboard of said friction ring root is provided with brake pad, and said brake pad and the outer side contacts of said telescopic pipe, when said telescopic pipe glides; Said friction ring receives downward frictional force, so that the bore in said friction ring tapering is drawn close to the friction ring center.

In the utility model, be positioned at the continuous controlling device in said friction ring root upper end, the outer side contacts of said controlling device and said telescopic pipe; When said telescopic pipe glided, said controlling device offered the downward power of said friction ring, so that the bore in said friction ring tapering is drawn close to the friction ring center.

In the utility model, said controlling device is a ring.

The utility model has following advantage compared with prior art:

1, after locking device is all opened, telescopic pipe can slowly descend, and can avoid falling rapidly of the flexible supporter and the object of hanging, to prevent that object from smashing or danger such as injury to personnel;

2, when this awl claw type friction ring received downward frictional force, each pawl of friction ring can be drawn close from the trend axle center, has increased axial locking power;

3, can finely tune up and down through the controlling device that the friction ring upper end is settled, to change the damping size that telescopic pipe moves up and down.Thereby suffered damping in the time of can selecting telescopic pipe according to actual needs and move.

Embodiment

Below will combine accompanying drawing and specific embodiment further to set forth the advantage of the utility model.

See also Fig. 1 and Fig. 2, be the utility model one embodiment's structural representation.The utility model is that example is explained with the flexible supporter, and flexible supporter 10 is made up of telescopic pipe 101, fixed tube 102 and locking device 103.Fixed tube 102 is accommodated telescopic pipe 101; Telescopic pipe 101 can be stretched up and down, and locking device 103 is as shown in Figure 1 to be socketed in around the jointing of fixed tube 102 and telescopic pipe 101, and it comprises locking knob 201 and shell 202; When locking knob 201 is screwed; Telescopic pipe 101 relative fixed pipes 102 are static, and when locking knob 201 was opened, telescopic pipe 101 relative fixed pipes 102 were descending motion.In addition; The upper end of locking device 103 is provided with the upper end slide block 205 that leans on mutually with telescopic pipe 101 outsides; And the lower end of telescopic pipe 101 is provided with the lower end slide block 206 that leans on mutually with fixed tube 102 inboards, and upper end slide block 205 can make telescopic pipe 101 when doing fore and aft motion, reduce with lower end slide block 206 and rock.

In conjunction with Fig. 2 and Fig. 3, a tapered friction ring is installed, preferred awl claw type friction ring 203 as shown in Figure 3 between telescopic pipe 101 and fixed tube 102; Friction ring 203 is socketed in the outside of telescopic pipe 101; And the inner surface of friction ring 203 contacts with the outer surface of telescopic pipe 101, when locking knob 201 is opened, forms certain force of sliding friction when telescopic pipe 101 is glided and between the friction ring 203; Thereby telescopic pipe 101 is in damping state in downslide, and the speed of decline is corresponding to slow down.Under this mode of execution, its tapering 301 or down all can provide certain frictional force up when friction ring 203 installed and fixed when the downslide of telescopic pipe 101, and therefore, the various installation directions of friction ring 203 all can reach the technique effect of the utility model.

In addition, the shape of friction ring is not limited to them, in the time of only need it being socketed in telescopic pipe; The outer side contacts of one end of this friction ring or whole inwall and telescopic pipe can provide frictional force to get final product when telescopic pipe glides, therefore; Friction ring preferred taper or the awl claw type, selects for use the friction ring that external diameter is identical in the two ends, external diameter differs all can be applied to the utility model in embodiment, also can be according to the outward appearance needs; The friction ring of other shapes is set, for example serpentine etc.

More preferably; As shown in Figure 2, the tapering 301 of friction ring 203 is towards the below, and its tapering is near the outside of telescopic pipe 101; Be connected with a controlling device 204 in the upper end of friction ring 203; This controlling device 204 can be a slide block structure, is preferably ring, and its inboard is leaned on respectively at the outside of said telescopic pipe 101, the inboard of locking device 103 with the outside mutually; After locking knob 201 unclamps; Telescopic pipe 101 moves downward; Controlling device 204 can receive downward frictional force; When offering the power that awl pawl type friction ring 203 compresses then downwards, the pressure that increases friction ring 203 and telescopic pipe 101 can be drawn close to the ring center in the tapering 301 of friction ring 203 under the guiding of definite value bore, thereby has increased the force of sliding friction of telescopic pipe 101; Reached that telescopic component still is in certain damping state when locking knob is in relaxed state, avoided telescopic component to fall rapidly.

In addition; Also can brake pad 302 be set in the root inboard of friction ring 203; And brake pad 302 and telescopic pipe 101 outer side contacts, when telescopic pipe 101 glided, friction ring 203 received the downward frictional force that telescopic pipe 101 provides; So that the bore in the tapering of friction ring 203 draws close to the friction ring center, and then the damping of increase and telescopic pipe 101.

Above-mentioned brake pad 302 is similar with the effect of controlling device 204, all is when further increasing telescopic pipe 101 motions and the frictional force of friction ring 203, and dual mode is got one and got final product, also can coupling.

The utility model has preferred embodiment; And be not that the utility model is done any type of restriction; Any technician who is familiar with this field possibly utilize the technology contents change of above-mentioned announcement or be modified to the effective embodiment who is equal to; In every case the content that does not break away from the utility model technological scheme, all still belongs in the scope of the utility model technological scheme any modification or equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
