Description
Technical field
The utility model belongs to liftable supporter, refers in particular to a kind of fast stepless lifting structure for tripod.
Background technique
Stepless lifting structure is as a kind of structure that can regulate arbitrarily height within the specific limits, and it is widely used in various tripod, can meet and be positioned at equipment on tripod to the requirement of certain limit arbitrary height operation.Although tripod itself is provided with fixed block with stable installation position equipment thereon; but be not provided with any effective protection measure; make still likely because misoperation or its equipment too heavy or meet accident; lifting structure is caused to decline suddenly; equipment on it is fallen damage on the ground, or equipment because of impulse force too large and fragile.
Summary of the invention
For the defect of prior art, the utility model provides a kind of fast stepless lifting structure for tripod, and its structure is simple, can realize stepless lifting rapidly, and security protection performance is good.
For achieving the above object, the utility model is by the following technical solutions:
For a fast stepless lifting structure for tripod, lower end is supported by three-leg support, includes thimble assembly, pipe close assembly, locking element and guide-localization part, and the two ends of described thimble assembly are located at by described pipe close assembly; Described locking element is for locking the sleeve pipe in described thimble assembly; Described thimble assembly comprises at least two sleeve pipes, between described sleeve pipe, noose connects, described locking element is arranged between every two sleeve pipes, is sheathed on the less sleeve pipe of caliber, and guide-localization part is arranged between every two sleeve pipes, for location and the guiding of each sleeve pipe; Also comprise the one-way relief valves for sealing described sleeve pipe, described one-way relief valves is arranged at the underpart of the sleeve pipe that diameter is less among every two sleeve pipes.
Further, described thimble assembly comprises two sleeve pipes, is respectively bassoon and tubule.
Further, described one-way relief valves is made up of materials such as soft rubber or macromolecular materials.
Further, fast stepless lifting structure also comprises the assembling set for fixing other equipment.
Further, the bottom of described one-way relief valves is taper, and the internal void of middle part and described sleeve pipe seals.
Further, described locking element is configured as axial deviation coning sleeve, and the axis of described axial deviation coning sleeve and the shaft axis of described thimble assembly have parallel error.
Further, the parallel error between the axis of described axial deviation coning sleeve and the shaft axis of described thimble assembly is 0.5 ~ 2mm.
The utility model compared with prior art, its beneficial effect is: its lower end that the caliber in thimble assembly is less installs unmarried safety valve, it is too fast and play compressed-air actuated effect that it can be equipped with weight unexpected lower slider hourly velocity above lifting structure, gliding more, snapback's resistance is larger, thus prevents the sleeve pipe because caliber is less from declining rapidly and injuring user; Locking element is configured as axial deviation coning sleeve, makes the journal offset of thimble assembly form mechanical locking, thus realizes fast stepless locking; Part of the present utility model is few simultaneously, and assembling is simple, low cost of manufacture.

Reference character: fast stepless lifting module 2, thimble assembly 21, tubule 211, bassoon 212, pipe close assembly 22, locking element 23, guide-localization part 24, one-way relief valves 26.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 ~ 5, the lower end of fast stepless lifting module 2 is supported by three-leg support, includes thimble assembly 21, pipe close assembly 22, locking element 23, guide-localization part 24 and one-way relief valves 26.
Thimble assembly 21 comprises at least two sleeve pipes, and sleeve pipe is sheathed successively, and one-way relief valves 26 is arranged on the lower end being sheathed on inner sleeve pipe.In the present embodiment, thimble assembly 21 is set to two sleeve pipes, is respectively tubule 211 and bassoon 212, and wherein bassoon 212 is sheathed on outside tubule 211; Pipe close assembly 22 is divided into again little pipe close and large pipe close, and little pipe close is plugged in the upper end of tubule 211.Large pipe close is plugged in the lower end of bassoon 212.
As shown in Figure 3, locking element 23 is for the sleeve pipe between locking sleeve assembly 21, axial deviation coning sleeve is configured as at the locking element 23 of the present embodiment, the shaft axis of the sleeve pipe of its axis and thimble assembly 21 has a parallel error X, in the specific implementation, the value of parallel error X is determined according to bearing weight and sleeve pipe size, generally can select between 0.5 ~ 2mm.Locking element 23, namely axial eccentric coning sleeve, makes the journal offset X of large tubule form mechanical locking, has axial deviation coning sleeve freely to slide up and down at tubule 211 overcoat; When tubule 211 rise and decline arbitrary position time, as long as axial deviation coning sleeve falls entangle bassoon external taper, at once lock tubule 211 can not move, as long as with hand slightly mention axial deviation coning sleeve tubule 211 just can on move down.
Guide-localization part 24 is located between bassoon 212 and tubule 211, relative position for locating sleeve and the relative movement to each sleeve pipe play the guiding role, i.e. large intercanalicular relative position, makes tubule 211 can not swing in bassoon 212, and prevents tubule 211 to move up bassoon 212.
As shown in Figure 2, the bottom of one-way relief valves 26 is taper, and the internal void of middle part and described sleeve pipe seals, and it is arranged at tubule 211 lower end, for Sealed casing pipe.When tubule 211 declines rapidly, the air in the bassoon 212 of tubule less than 211 is compressed thus is produced resistance upwards, prevents because tubule 211 declines rapidly and injures user.
Further, one-way relief valves 26 is made up of materials such as soft rubber or macromolecular materials, and its elasticity is better, provides enough buffer time better, strengthen the Safety performance of stepless lifting structure for tubule declines.
Further, being also provided with the assembling set for fixing other equipment above tubule, can be connecting plate or iron plate, when assembling set is connecting plate, can be fixed on connecting plate by screw by other equipment; When assembling set is iron plate, the equipment with magnetic coupling can be fixed on iron plate by magnetic.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
