Abstract
The utility model discloses an alpenstock external lock, and relates to a locking device used for locking two adjacent member bars to be connected or loosening the two adjacent member bars for separating the member bars. The alpenstock external lock structurally comprises an annular lock catch, a screw rod, a nut, a spanner buckle and the like. A sleeve chuck structure is additionally arranged in the annular lock catch, the upper end of a sleeve chuck is directly fixed on an upper rod, and the lower end of the sleeve chuck is movably arranged on a lower rod in a sleeved mode. An open slot is designed at the lower end of the sleeve chuck. The annular lock catch is arranged at the lower end of the sleeve chuck in a sleeved mode. Due to the fact that the structure that the upper rod and the lower rod are respectively and independently connected is adopted, the appearance of the whole external lock is designed to be small, exquisite and attractive, and the occurrence that the lock catch is lost can be prevented. Meanwhile, the lower rod can be clamped and locked by a manner that the annular lock catch is arranged at the lower end of the sleeve chuck in the sleeved mode. Due to the facts that the friction force between the sleeve chuck and the lower rod is large and locking of the lower end has no direct relationship with the upper rod, the upper rod cannot be machined any more, processes of machining the upper rod are reduced, production cost is reduced, and the upper rod and the lower rod can have reliable locking force.
Description
Technical field
The utility model relates to a kind of outer lock construction that is used to lock or unclamp adjacent two rod members connection or disengaging, is meant the alpin-stock external lock specifically.
Background technique
Common alpin-stock all has telescopic member structure, so both for convenience detach carrying, also can carry out elongating or shortening of rod member according to actual needs, and flexible mainly inner lock of the rod member of present alpin-stock or external lock are locked, interior lock construction such as disclosed China Patent No. are 201020282970.2 " a kind of alpin-stock that can regulate length ", and it is to be made of disjunctor pedestal, screw rod, expansion sleeve, taper inner core, jump ring and spring etc.; And outer lock construction such as disclosed China Patent No. are 200920153925.4 " plate button external lock alpin-stock ", it is by annular snap close, screw rod, formations such as nut and spanner button, this ring lock is buckled also, and design has two connecting sheets and locked groove, be sleeved on the flexible rod member enterprising enforcement time spent that constitutes by upper boom and lower beam when external lock, the opening slot structure that one end opening also must be arranged in last boom end design, after in lower beam stretches into upper boom, by closing the spanner button through screw rod, nut drives two connecting sheets and inwardly pushes, dwindle locked groove, thereby realize annular snap close obvolvent upper boom, upper boom obvolvent lower beam forms telescopic locking; And open the spanner button, the mutual obvolvent coupling mechanism force between annular snap close, upper boom and the lower beam disappears, and can stretch again again between the upper and lower bar.
Above-mentioned outer lock construction in actual use, because annular snap close mainly is to form telescopic locking by the mutual obvolvent coupling mechanism force that increases between the upper and lower bar, so have many defectives: one, upper and lower bar all is a metallic rod, frictional force each other is less, in case extraneous stressed bigger, cause the coupling mechanism force between the upper and lower bar to be cancelled easily, thereby the upper and lower bar when causing locking also can be flexible relatively, reduces reliable lock; Two, must have the opening slot structure of an end opening could realize the locking of upper and lower bar in last boom end design, this have both reduced the intensity of rod member, had also increased manufacturing procedure, had improved cost of production; Three, dismounting annular snap close and rod member and when carrying, annular snap close is independently to separate with rod member, causes the loss of annular snap close easily; Four, annular snap close, upper boom and lower beam are obvolvents successively, and this can cause, and full annular snap close volume increases, profile is clumsy ugly.
Summary of the invention
Technical problem to be solved in the utility model be to overcome the defective of prior art and provide small and exquisite attractive in appearance, the reliable lock of a kind of profile, cost lower, be difficult for the alpin-stock external lock lost.
Technical problem of the present utility model is achieved through the following technical solutions:
A kind of alpin-stock external lock, be installed between the upper boom and lower beam of alpin-stock, it comprises the annular snap close of a hollow structure, this annular snap close one side is provided with the axially extended locked groove along annular snap close, and be respectively equipped with outward extending connecting sheet in the locked groove both sides, the screw rod, nut and the spanner that locking are installed on these two connecting sheets or unclamp locked groove are buckled, be provided with the cutting ferrule of hollow structure in the described annular snap close, this cutting ferrule upper end is fixed on the upper boom, the lower end movable set also is provided with axially extended opening slot along cutting ferrule in cutting ferrule lower end one side on lower beam; Described ring lock anchors the position and is sleeved on the cutting ferrule lower end.
Described cutting ferrule upper end inwall is provided with anti-skidding line.
Described cutting ferrule outer surface is provided with a short groove that radially extends along cutting ferrule, and this weak point groove is connected with the opening slot of cutting ferrule lower end one side.
The setting sleeve assembling structure of described annular snap close and cutting ferrule lower end is to be provided with location equipped locating slot and positioning block between annular snap close inwall and cutting ferrule lower end outer surface.
The mounting structure that screw rod, nut and spanner on described two connecting sheets buckled is that screw rod passes two connecting sheets nut that has been threaded successively, the curved shape of described spanner button, the one end is the rounded end on screw rod of being articulated and connected, the other end is unsettled operating end, this rounded end outer surface is a camming surface, and contact is on connecting sheet.
Described nut is inlaid in to be regulated in the cap, and this adjusting cap outer circumferential face is provided with the slideproof tooth of circle distribution, regulates the cap exterior edge face and is provided with cross recess.
Described annular snap close outer surface is provided with for the equipped shallow slot of spanner button obvolvent.
Compared with prior art, the utility model mainly is to have additional the cutting ferrule structure in the annular snap close of alpin-stock external lock, this cutting ferrule upper end directly is fixed on the upper boom, cutting ferrule lower end movable set is on lower beam, also designed opening slot in the cutting ferrule lower end, annular snap close then is sleeved on the cutting ferrule lower end, and this upper and lower bar carries out the structure of separate connection respectively, it can make can prevent the loss of annular snap close again by the more small and exquisite attractive in appearance of whole external lock configuration design.Simultaneously, can realize through the cutting ferrule lower end obvolvent of lower beam is locked by annular snap close, because the frictional force between cutting ferrule and the lower beam is bigger, and the locking and the upper boom of lower beam do not have direct relation, so need not again upper boom to be processed, the manufacturing procedure that this can reduce upper boom reduces production costs, and makes again to possess more reliable coupling mechanism force between the upper and lower bar.
