Referring to Figures 1 and 2, the present invention is a kind of drawstring adjustable type alpin-stock, including first support bar 1, described first
Strut 1 is provided with accommodating cavity；Second support bar 2, one end slidable connection first support bar 1 of the second support bar 2, and can portion
Divide and be accommodated in accommodating cavity；In order to realize second support bar 2 in optional position locking in first support bar 1 to reach alpin-stock
Length adjustment, also sets up retaining mechanism, and the retaining mechanism is located at one end in connection first support bar 1 of second support bar 2,
Relative position for locking second support bar 2 and first support bar 1；Controlling organization, the controlling organization is located in accommodating cavity,
Locking state for releasing retaining mechanism, to realize that second support bar 2 stretches into the length adjustment in first support bar 1.
As shown in Figures 1 to 5, the retaining mechanism includes slide bar 3, the first drive sleeve 5, the second drive sleeve 4, bidirectional locking
Set 6, (the first back-moving spring 8 and second back-moving spring 7.As shown in figure 1, the lower end of the slide bar 3 is fixedly connected second support bar 2.
As shown in Figure 3 and Figure 4, first drive sleeve 5 is slidably socketed on slide bar 3, and the first drive sleeve 5 is provided with the first dead bolt；
Second drive sleeve 4 is slidably socketed on slide bar 3, and the second drive sleeve 4 is provided with the second dead bolt；The bidirectional locking set 6
Two ends are socketed the first drive sleeve 5, the second drive sleeve 4 respectively, and are correspondingly arranged respectively for housing the first dead bolt, second in two ends
The first dead bolt position of dead bolt, the second dead bolt position；First dead bolt is set to up big and down small wedge shaped projection, second dead bolt
It is set to up-small and down-big wedge shaped projection, the first dead bolt position, the second dead bolt position is correspondingly arranged is wedge-shaped groove, the first dead bolt
The first dead bolt position and the second dead bolt position are extruded by lozenges respectively with the second dead bolt, bidirectional locking set is flared out.It is described
(the first back-moving spring 8 is sheathed on slide bar 3, and against the end of slide bar 3, the other end is against the first drive sleeve 5 for its one end；Described second
Back-moving spring 7 is sheathed on slide bar 3, and its one end is resisted against the other end of the slide bar 3 relative to (the first back-moving spring 8, its other end
Against the second drive sleeve 4.First drive sleeve 5, the second drive sleeve 4 are respectively in (the first back-moving spring 8, second back-moving spring 7
In the presence of, the first dead bolt position, the second dead bolt position are extruded by the first dead bolt, the second dead bolt, bidirectional locking is covered 6 two ends and open
With the relative position that locking second support bar 2 and first support bar 1 are realized in the friction of accommodating cavity wall.
For the ease of singlehanded control, the controlling organization includes lanyard assembly and starts component, and the lanyard assembly is located at
In accommodating cavity, lanyard assembly is provided with a drawstring 9, and the one end of the drawstring 9 connects the first drive sleeve 5, and other end connection second is driven
Set 4；The other end for starting component located at first support bar 1 relative to second support bar 2, starts component and is provided with and drawstring
9 press sections for coordinating, for realizing pulling the first drive sleeve 5, the counter motion of the second drive sleeve 4 by pressing drawstring 9, release
The locking state of retaining mechanism.
As shown in Figure 1, Figure 2, shown in Fig. 6, Fig. 7 and Fig. 9, the lanyard assembly includes：Fixed cover 10, the fixed cover 10 is fixed
The other end of the first support bar 1 relative to second support bar 2 is connected, fixed cover 10 is provided with first spacing group；Connecting rod 11, it is described
Connecting rod 11 is arranged in retaining mechanism, and the one end of connecting rod 11 is fixedly connected fixed cover 10, and the other end is provided with second spacing group；Drawstring 9,
The one end of the drawstring 9 connects the first drive sleeve 5, spacing group, second spacing group the second drive sleeve of connection 4 of other end pile warp first.
Because drawstring 9 needs to slide in the course of the work, first spacing group, second spacing group may be configured as the smooth slide bar in surface or fixed
First spacing group is specifically horizontally disposed two the first fixed pulleys 91 by pulley, the present embodiment；Second spacing group of setting
It is one second fixed pulley 92.During due to regulation alpin-stock length, retaining mechanism is slided up and down on connecting rod 11, and the present embodiment will draw
Rope 9 is in connecting rod 11.As shown in Figure 10, the both sides of connecting rod 11 open up the first groove for wearing drawstring 9, have been so designed that both just
In the installation of drawstring 9, the installation of the second fixed pulley 92 is also allowed for.As shown in Figures 6 to 9, in order to avoid on drawstring 9 and connecting rod 11
End frictional dissipation, two the 4th fixed pulleys 94 are set in the lower end of fixed cover 10, and drawstring 9 is from two outer ends two of the first fixed pulley 91
Enter in connecting rod 11 in the middle of individual 4th fixed pulley 94.As shown in figure 5, being driven for the ease of the drive sleeve 5, second of drawstring 9 and first
Set 4 is fixedly connected, and slide bar all opens up the second groove about 3, bearing pin is correspondingly arranged in the first drive sleeve 5, the second drive sleeve 4,
Bearing pin can be in sliding in the second groove, and the two ends of drawstring 9 are respectively fixedly connected with a bearing pin.
As illustrated in figures 1 and 8, the startup component is set to a button 12, the slidable connection fixed cover of the button 12
10, button 12 is provided with the press section for pressing drawstring 9 between first spacing group, second spacing group, and the press section passes through
Pressing drawstring 9 realizes that drawstring 9 pulls the first drive sleeve 5, the counter motion of the second drive sleeve 4, releases the locking state of retaining mechanism.
As shown in Figure 8, Figure 9, for the ease of the slip of drawstring 9, the end of press section sets the 3rd fixed pulley 93.
In being provided with the 3rd back-moving spring 13 in accommodating cavity, described one end of 3rd back-moving spring 13 is against fixed cover for the present embodiment
10, the other end is against slide bar 3.
A kind of drawstring adjustable type alpin-stock of the present embodiment, in normal state, retaining mechanism is in the top of second support bar 2
The relative position of the first support bar that is locked 1 and second support bar 2.During adjustment length, one hand holds fixed cover 10, and pressing is pressed
Key 12, the 3rd fixed pulley 93 pushes drawstring 9 between two the first fixed pulleys 91, make drawstring 9 pull respectively the first drive sleeve 5,
The counter motion of second drive sleeve 4, makes the first dead bolt, the second dead bolt release the extruding to the first dead bolt position, the second dead bolt position, two-way
Lock sleeve 6 recovers deformation, and no longer to the inwall friction lock of first support bar 1, now the 3rd back-moving spring 13 is by extruding slide bar
3, second support bar 2 is moved down, alpin-stock length increases, and to shorten alpin-stock length, holds fixed cover 10 and pushes, and overcomes the
The active force of three back-moving springs 13, you can make second support bar 2 take in accommodating cavity, alpin-stock length is shortened.Adjust to suitable length
After degree, button 12 is unclamped, the first drive sleeve 5, the second drive sleeve 4 are respectively in (the first back-moving spring 8 and the work of second back-moving spring 7
Homing is firmly descended, while driving drawstring 9, makes drawstring 9 that button 12 be pushed up back into original position by the 3rd fixed pulley 93.
A kind of drawstring adjustable type alpin-stock of the present embodiment, it is singlehanded can easily, freely adjustment length, it is easy to use,
It is practical.
Above-described embodiment is preferred scheme of the invention, and the present invention can also have other embodiments.The technology of this area
Personnel can also make equivalent variations or replacement on the premise of without prejudice to spirit of the invention, and these equivalent modifications or replacement are wrapped
It is contained in the scope set by the application claim.
