Abstract
The utility model discloses an internal lock of an alpenstock, and relates to a locking or unlocking structure for a telescopic rod piece of the alpenstock. The internal lock mainly comprises a base, a screw rod, an expansion sleeve, a conical inner core, a snap spring and the like. In a technical scheme disclosed by the utility model, the conical inner core and the screw rod constituting an internal lock structure of the alpenstock are mainly in threaded connection with each other, and the expansion sleeve is movably sleeved outside the conical inner core. In an improved structure, the conical inner core moves axially along the screw rod, and enters and exits from the expansion sleeve to form locking or unlocking; the structure is simpler; compared with the conventional internal lock structure of an alpenstock, the internal lock has the advantages of labor-saving assembly, low cost, quick and reliable locking and the like, and has light weight; and moreover, each assembly can be detached separately, and is convenient to maintain.
Description
Technical field
The utility model relates to a kind of interior lock construction, especially alpin-stock internal lock.
Background technology
Common alpin-stock all has telescopic member structure, so just can carry out elongating or shortening of rod member according to actual needs, and the flexible mainly inner lock of rod member locks.At present the interior lock construction of alpin-stock is that screw rod, expansion sleeve, taper inner core, jump ring and spring etc. by the disjunctor pedestal constitute basically; Like disclosed Chinese patent number be 201020282970.2 " a kind of alpin-stock that can regulate length "; The interior lock construction that this patent disclosed is that the taper inner core is fixed on the screw rod, and expansion sleeve is threaded on the screw rod, and the screw rod rear portion is attached on the rod member tube wall expansion sleeve by spring push; After flexible rod member rotates mutually; The taper inner core gets in the expansion sleeve, and the elastic groove through expansion sleeve rises by expansion sleeve to be squeezed on the rod member tube wall greatly, to lock thereby form.The assembly of lock construction is comparatively various, bulky in above-mentioned, also must just can lock by the elastic force of spring in the actual use, and this elastic force for spring is had relatively high expectations; Also improved production cost; And the many Heavy Weights of assembly, the assembling maintenance is trouble comparatively, influences dependability.
Summary of the invention
The utility model technical problem to be solved be to overcome the defective of prior art and provide a kind of simple in structure, the assembling laborsaving, the locking reliable, lower-cost alpin-stock internal lock; The collapsing length locking that possesses the alpin-stock rod member of lock construction in this is more quick; And in light weight, each assembly can both be dismantled separately, also is convenient to maintenance.
The technical problem of the utility model realizes through following technical scheme:
A kind of alpin-stock internal lock; Be installed in the flexible rod member of alpin-stock, it comprises screw rod, expansion sleeve taper inner core and the jump ring of disjunctor pedestal, and the interior boom end of this pedestal and flexible rod member is fixed; This expansion sleeve is provided with a plurality of elastic grooves, and described taper inner core is connected with screw flight; Described expansion sleeve movable set is outside the taper inner core.
Core outer surface is provided with gib block in the described taper.
Described screw rod is provided with annular groove, is provided with the interior shoulder with this annular groove active mounting in the described expansion sleeve.
Described elastic groove is 3 ~ 6 of circumference uniform distribution.
Described pedestal outer surface is provided with fixedly annular groove of multiple tracks.
Compared with prior art; The utility model mainly is that the taper inner core that constitutes lock construction in the alpin-stock is connected with screw flight; And the expansion sleeve movable set is outside this taper inner core; Structure after the improvement is to move and pass in and out along screw axial through the taper inner core to form locking or release in the expansion sleeve, and this structure is more simple, compares the interior lock construction of traditional alpin-stock and also has advantages such as assembling is laborsaving, cost is lower, locking is fast reliable; And in light weight, each assembly can both be dismantled separately, also is convenient to maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the three-dimensional exploded view of Fig. 1.
The specific embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
Like Fig. 1, shown in Figure 2,1. fixedly annular groove, 2. shoulder in the expansion sleeve, 21. elastic grooves, 22., 3. taper inner core, 31. gib blocks, 4. jump ring, 5. screw rod, 51. annular grooves of pedestal, 11..
The alpin-stock internal lock mainly is installed in the flexible rod member (not shown) of alpin-stock, and locking or release is provided for rod member flexible.
Lock construction comprises screw rod 5, expansion sleeve 2, taper inner core 3 and jump ring 4 in described.
Described screw rod 5 adopts the lighter aluminium of weight to process; Its bottom is the pedestal 1 of disjunctor; This pedestal outer surface is provided with the fixedly annular groove 11 that multiple tracks radially distributes, this fixedly annular groove be mainly used in the end that pedestal 1 is fixed on flexible rod member, generally be the interior boom end that is fixed on flexible rod member; Screw rod 5 top necks are with plastics fabrication spring 4.
Described screw rod 5 is provided with the taper inner core 3 that is threaded; The conical top of this taper inner core towards pedestal 1, bottom towards jump ring 4; Outer surface at the taper inner core also is provided with two along the axially extended gib block 31 of taper inner core; These two gib blocks are that the center is symmetrical set with the center of circle of taper inner core 3, and play the taper inner core is done axially-movable along screw rod 5 guide effect.
Described expansion sleeve 2 is sleeved on outside the taper inner core 3; This expansion sleeve also is provided with the elastic groove 21 of 4 circumference uniform distributions outward; Shoulder 22 in the expansion sleeve inwall is provided with; Set annular groove 51 active mountings on shoulder and the screw rod 5 in being somebody's turn to do are so can make expansion sleeve 2 relative screw rods 5 can only radially rotate and can't move axially through this annular groove.
The utility model mainly is fixed on the interior boom end of flexible rod member through pedestal 1; And join in the outer bar that is inserted in flexible rod member with interior bar; Simultaneously expansion sleeve 2 is attached on the outer rod tube wall, behind the interior bar that rotates flexible rod member arbitrarily each other and outer bar, owing to the frictional force of outer rod tube wall is bigger; So the expansion sleeve 2 that is attached on the outer rod tube wall rotates in company with outer bar together; It then is to drive screw rod 5 to rotate together that interior bar rotates, and after interior bar phase outer pole is rotated, can drive taper inner core 3 through the screw rod rotation and move in the expansion sleeve 2 along screw axial like this; The bottom of taper inner core can be impelled expansion sleeve 2 outwards to open to expand and closely is squeezed on the outer rod tube wall, and this moment, flexible rod member promptly was in the lock state; And after the opposite spin of interior bar phase outer pole, can drive taper inner core 3 through screw rod 5 again in expansion sleeve 2, to come out, expansion sleeve and outer rod tube wall do not have tight extruding relation, and this moment, flexible rod member promptly was in the release Telescoping.This interior lock construction locking is quick, in light weight, each assembly can both be dismantled separately, is convenient to maintenance.
