Embodiment
See also Figure 1 and Figure 2, the utility model provides a kind of nothing section brake flexible rod structure, it includes and manages 2, one axle 3, a brake group 4 and a junction 5 in the outer tube 1,, outer tube 1 wherein is the shape of a hollow tubular body, its inside is formed with a containing space 12, and containing space 12 can be in order to members such as pipe 2, axle 3 and brake group 4 in holding.
Manage in 2 during axle 3 movably is arranged at, the two ends of pipe 2 during stretch out at the two ends of axle 3, one end of axle 3 also stretches out outer tube 1, the end that axle 3 is stretched out outer tube 1 can have a perforation 34, this perforation 34 can further connect an operation equipment (not shown), so that pulling or press axle 3 carrying out telescopic moving, but the structure of operation equipment do not limit, and can otherwise replace or be omitted yet.
The quantity that brake group 4 arranges can be one, to constitute unidirectional nothing section brake flexible rod.Brake group 4 also can be set to two, to constitute two-way no section brake flexible rod, then is to be provided with a brake group 4 in this enforcement.The element of wherein, brake group 4 includes a ball base 41, a plurality of ball 42, a wedge shape part 43, one first elastic element 44, a pushing part 45, one second elastic element 46 and a supporting base 47.Axle 3 is passed second elastic element 46, wedge shape part 43, ball base 41, first elastic element 44 and supporting base 47 in regular turn, to reach said elements is serially connected with on the same axle center.
Further say, as shown in Figure 3, when first elastic element 44 is bestowed ball base 41 and is moved towards wedge shape part 43 directions, can utilize plane of inclination 431 these balls 42 of promotion of wedge shape part 43 radially mobile outward along flexible rod, make these balls 42 optionally packing be fixed in the inner edge of outer tube 1, even also these ball 42 packings are fixed between outer tube 1 inner edge and the wedge shape part 43, thereby fixed between outer tube 1 and the middle pipe 2, to reach the effect of brake (location), the flexible rod that stretches after adjusting is fixed.
Therefore the collocation of wedge shape part 43 and the ball 42 by brake group 4, in order to the brake strength of flexible rod to be provided, also namely when axle 3 is born the strength of compression, can be fixed between outer tube 1 inner edge and the wedge shape part 43 because of these ball 42 packings of brake group 4, and provide the strength of carrying, axle 3 can't be moved to the direction of compressing force, reaching the effect of brake (location), and then make axle 3 can bear the strength of external compression.
In addition, pushing part 45 is the hollow tube-shape body in the present embodiment, the mode of its setting is 45 to offer first fixed hole 451 in the pushing part, again first fixed block 22 was worn first fixed hole 451 and be fixed on pipe 2 the concave ring part 21, to reach pushing part 45 is fixed on the middle pipe 2, so pushing part 45 has continuous action relation with middle pipe 2.And an end of pushing part 45 coats a part of wedge shape part 43, and the other end butt of pushing part 45 or be adjacent to the collar 11 is positioned at the purpose that arranges that 45 inboards, pushing part also can arrange second elastic element, 46, the second elastic elements 46 and is pushing part 45 pushed home.
See also shown in Figure 3, this moment since these ball 42 packings be fixed between outer tube 1 inner edge and the wedge shape part 43, but thereby axle 3 application of forces outwards do the action that draws high, but axle 3 can't move to the direction of compressing.In more detail, when axle 3 application of forces were outside, these balls 42 rolled along the plane of inclination 431 of wedge shape part 43, and then these balls 42 are got loose in outer tube 1 inner edge, make axle 3 draw high adjustment.Yet, when axle 3 application of forces are compressed, these ball 42 packings are fixed between outer tube 1 inner edge and the wedge shape part 43, and then make axle 3 to compress, and axle 3 can be born the strength of external compression, the flexible rod that stretches after adjusting is fixed, therefore can be reached the effect of brake (location).
See also shown in Figure 4, when in the user presses, managing 2, in pipe 2 can make pushing part 45 synchronous moving, can utilize pushing part 45 to promote these corresponding balls 42 and directly yearn for interior movement along flexible rod, these balls 42 are got loose in outer tube 1 inner edge, and the user can compress adjustment by center roller 3.Thereby user such as desire shorten the length of flexible rod, pipe 2 in can pressing, and the axle 3 of this moment can be compressed and adjust and then shorten length, therefore can make the shorten length of flexible rod.
Flexible rod of the present utility model can be applicable to sports equipment, fitness equipments, medical equipment (as infusion stand), electrical appliance (as electric fan) and furniture article such as (as the desktops of desk).The set joint 5 of an end that can be by outer tube 1, the object that is connected with the institute desire connects.
As long as the utility model is the pressing of pipe 2 in utilizing, and can interlock pushing part 45 removes to promote these corresponding balls 42 and directly yearns for interior movement along flexible rod, and these balls 42 are got loose in outer tube 1 inner edge, the adjustment that axle 3 can be compressed.In addition, the adjustment that axle 3 also can draw high is outwards pulled out axle 3, so flexible rod can stretch easily and adjusts length.And in decontroling pipe 2 press the application of force, can recover brake (location), brake operation is simple and convenient, use that can convenient flexible rod.
Just the above only is preferred embodiment of the present utility model; non-ly be intended to limit to claim protection domain of the present utility model; so the equivalence of using the utility model specification and graphic content to do such as changes; all in like manner all be contained in claims protection domain of the present utility model, close and give Chen Ming.
