Description
Technical field
It the utility model is related to a kind of locking mechanism flexible for locking or discharging inside and outside pole length, i.e., it is a kind of to rotate
Formula rod member locking mechanism.
Background technology
The locking mechanism for being presently used for inside and outside pole length telescopic locking is mainly made up of lock and lock tube, before the lock
End is provided with the shell fragment of multiple circumference uniform distributions, and interior bar is typically actively plugged in more by the lock tube turning set outside lock
In individual shell fragment, outer bar is fixedly mounted on lock rearward end, then lock tube positive and negative rotation can just extrude or discharge the pressure on multiple shell fragments
Power, then multiple shell fragments are locked with regard to that can be close to obvolvent in the realization of interior rod outer surface, or rod outer surface realizes scaling operation in disengaging.On
It is easy to operate to state locking mechanism, but has been found that in actual use, is close to multiple shell fragments in obvolvent by way of rod outer surface
To lock inside and outside bar, because shell fragment is all that rigid plastics is made, frictional force is smaller, and adhesive force is not strong, can also be made long afterwards using length
Into the abrasion of shell fragment and interior bar contact portion, the coupling mechanism force of locking mechanism is influenceed, causes the use reliability of whole locking mechanism
It is not good enough.
The content of the invention
The defects of technical problem to be solved in the utility model is to overcome prior art and provide a kind of adhesive force it is strong,
A kind of big, wear-resistant, reliable lock the rotary type rod member locking mechanism of frictional force.
Technical problem of the present utility model is achieved through the following technical solutions：
A kind of rotary type rod member locking mechanism, including the lock tube that lock and turning set are mounted in outside lock；Before described lock
The interior bar that end is provided with the shell fragment of multiple circumference uniform distributions and is actively plugged in multiple shell fragments；Described lock rearward end is provided with solid
The outer bar of Dingan County's dress, each shell fragment is made up of the integral locking plate of ebonite quadric injection mould and cushion compound, and the cushion compound is set
On the inner surface of locking plate；Described lock tube positive and negative rotation simultaneously drives the cushion compound to be close to interior rod outer surface or depart from outside interior bar
Surface.
Described cushion compound is soft silica gel piece.
Mounting groove is provided with the middle part of described locking plate inner surface, the inner closing of the mounting groove, outer end axially penetrate through locking plate；Institute
The cushion compound stated is inlaid in the mounting groove, and with the locking plate ebonite secondary injection molding.
Described locking plate and cushion compound is indent and the identical arc-like sheet for being close to interior rod outer surface.
For described locking plate one end disjunctor on lock, the other end is hanging.
Per the elongated slot that outward opening is equipped between two neighboring described shell fragment.
Compared with prior art, the utility model is mainly using the integral lock of ebonite quadric injection mould by each shell fragment
Piece and cushion compound are formed, and cushion compound is arranged on the inner surface of locking plate, then during lock tube positive and negative rotation, with regard to that can drive cushion compound
Rod outer surface in being close to interior rod outer surface or departing from, so as to realize locking or discharge the flexible purpose of inside and outside pole length, after improvement
Locking mechanism also have the advantages that adhesive force is strong, frictional force is big, wear-resistant, reliable lock.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 A-A cutaway view Amplified images.
Fig. 3 is the structural representation of lock.
Fig. 4 is the structural representation that Fig. 3 sheds cushion compound.
Embodiment
The utility model embodiment will be elaborated again by above-mentioned accompanying drawing below.
As shown in Fig. 1 ~ Fig. 4,1. locks, 11. shell fragments, 111. locking plates, 112. cushion compounds, 113. elongated slots, 114. mounting grooves,
2. lock tube, 3. interior bars, 4. outer bars.
A kind of rotary type rod member locking mechanism, as shown in figure 1, being related to a kind of be used for the scaling operation of interior bar 3 and outer bar 4
The locking mechanism of quick locking or quick release, it includes interior bar 3, outer bar 4, lock 1 and lock tube 2 etc., and the inside and outside bar uses
High-strength light tube and pipe of aluminium alloy makes, the lock 1 and the generally use high-quality plastic production of lock tube 2, and lock tube 2 rotates suit
Outside lock 1.
The described leading section of lock 1 is provided with the shell fragment 11 of 4 circumference uniform distributions, and according to actual needs, the shell fragment 11 counts
Amount can also set multiple, such as 2 ~ 6, per the elongated slot 113 that outward opening is equipped between two neighboring shell fragment 11, then pass through elongated slot
Shell fragment 11 can be made to form the hanging elastic construction in one end disjunctor one end.
The structure of each shell fragment 11 is identical, therefore the present embodiment is only described in detail by taking one of shell fragment as an example；
Described shell fragment 11 is made up of the integral locking plate 111 of ebonite quadric injection mould and cushion compound 112, one end disjunctor of locking plate 111
On lock 1, the other end is hanging, and is made with lock 1 using phase same material, and the cushion compound 112 is soft silica gel piece, is arranged on
On the inner surface of locking plate 111, its structure is：Be provided with mounting groove 114 in the middle part of the inner surface of locking plate 111, the mounting groove it is inner close,
Outer end axially penetrates through locking plate 111, and cushion compound 112 is directly inlaid in the mounting groove 114, then with the ebonite quadric injection mould of locking plate 111
Shaping.
Described interior bar 3 is actively plugged in 4 shell fragments 11, i.e., the view upper end shown in Fig. 1, then locking plate 111 and flexible glue
Piece 112 is both designed as indent and coincide to be close to the arc-like sheet of the outer surface of interior bar 3；Described outer bar 4 is fixedly mounted on the rear end of lock 1
Portion, the view lower end i.e. shown in Fig. 1；Therefore, when the positive and negative rotation of lock tube 2, with regard to obvolvent or the disengaging simultaneously of four shell fragments 11 can be extruded
Interior bar 3, then the cushion compound 112 on each shell fragment 11 is also just close to the outer surface of interior bar 3 or departs from the outer surface of interior bar 3, and difference is real
Now lock or discharge the flexible purpose of inside and outside pole length.Due to the material relation of cushion compound 112 itself, it is close to the appearance of interior bar 3
Face by with larger frictional force and stronger adhesive force, and it is wear-resistant, locking is relatively reliable.
Described above is only specific embodiment of the utility model, it should be appreciated by those skilled in the art that any and reality
The equivalent structure design of example is applied, should be included within the scope of protection of the utility model.
