Fig. 2 is that the utility model moves a figure.

Fig. 3 is that the utility model moves two figure.

Fig. 4 is that the utility model moves three figure.

Fig. 5 is the another embodiment sectional view of the utility model.

The specific embodiment:

See also Fig. 1, the utility model comprises door bolt column base 3 and door bolt post 2.This door bolt column base 3 is the ducted body that a back side is opened wide, and is provided with pivot groove 31 near inner chamber one end of its hollow, and this pivot groove 31 is symmetrically located at upper and lower inwall respectively and closely opens wide the place.Be provided with buckle 4 in these door bolt column base 3 inner chambers, the upper and lower both sides of an end of this buckle 4 are respectively arranged with pivot 41, and this pivot 41 is positioned at above-mentioned pivot groove 31; And this buckle 41 has button hole 42.These door bolt column base 3 two ends have perforation 32 and perforate 33 respectively.Door bolt post 2 is arranged in door bolt column base 3 inner chambers, and the one end passes from perforate 33; These door bolt post 2 upper sleeve throughs are provided with spring 7, and the other end is provided with keeper 5.These spring 7 two ends are resisted against keeper 5 respectively and door bolt column base 3 is provided with on the internal chamber wall of perforate 33 1 ends.Be provided with sliding bar 6 in this door bolt column base 3, this sliding bar 6 passes the button hole 42 of buckle 4, and the one end is connected with door bolt post 2 other ends, and its other end passes perforation 32.This sliding bar 6 wears and is provided with spring 61, and these spring 61 2 ends are resisted against on the end face of door bolt post 2 other ends/auxilliary strong dividing plate 34 respectively and on the end face of buckle 40.Buckle 4 is biased in pivot 41 rotation of a side around it, and tilts to intersect with sliding bar 6 under the effect of spring 61, and the button hole 42 on it is contacted with the shaft of sliding bar 6, with sliding bar 6 stoppers in a certain position.Door bolt column base 3 inner chambers are provided with an auxilliary strong dividing plate 34 in certain position, but the motion of its correcting sliding bar 6 and place restrictions on strokes in the door bolt post 2 withdrawal door bolt column bases 3, and the rigidity that can improve door bolt column base 3 prevents to produce distortion.The end that this door bolt column base 3 has perforation 32 also is provided with an aperture 35, and be equipped with control member 8 in this aperture 35, these control member 8 one ends stretch out in outside the door bolt column base 3, and the other end is resisted against on the end face of buckle 4, and it is positioned on the shaft of fastening column base 3 with a bolt or latch can be equipped with spring 81.During use, can promote buckle 4, be convenient to staff and control buckle 4 angles of inclination by pushing control member 8.In addition, the end that sliding bar 6 protrudes from door bolt column base 3 is fixed with pushing sleeve 1, controls the position of door bolt post 2 in order to staff.

See also Fig. 2, if push control member 8, force buckle 4 swings one angle, make button hole 42 release out sliding bar 6 (being that button hole 42 does not contact with sliding bar 6), can promote keeper 5 by the restoring force of spring 7, make and to contract in the door bolt post 2, drive sliding bar 6 overhanging (seeing shown in Figure 3) simultaneously, until keeper 5 with till auxilliary strong dividing plate 34 leans on mutually.Otherwise, as releasing by door bolt post 2, only need directly to promote pushing sleeve 1, allow and contract in the sliding part 6, fasten post 2 evaginations with a bolt or latch thereby drive.In this process, buckle 4 reduces its angle of inclination with sliding part 6 inside indentations, loosens the clip power of button hole 42 to it; In case stop to promote pushing sleeve 1, buckle 4 is a fulcrum with pivot 41 under the effect of spring 61, and the angle that tilts makes that the button hole 42 on the buckle 4 fastens sliding bar 6 (being that button hole 42 contacts with sliding bar 6), recovery stops on the desired location and will fasten post 2 with a bolt or latch the clamping function of sliding part 6; So can reach the position (as shown in Figure 4) of stepless control door bolt post 20.

In addition, this sliding bar 6 can be designed to the ratchet face (not shown) with these button hole 42 contacted faces, in the hope of increasing the ability that button hole 42 fastens sliding bar 6 location.

What deserves to be mentioned is, can set up a guide hole 43 on this buckle 4, and can set up one in control member 8 the inners and be little guide pillar (not shown), make this guide pillar penetrate in this guide hole 43, make the state of deflection about more can not producing when making buckle 4 do swing far beyond guide hole 43.For preventing the left and right sides deflection of above-mentioned buckle 4, can use door bolt column base 3 ' shown in Figure 5, on the door bolt column base 3 ' inner chamber/the contiguous perforation of lower wall 32 places are provided with pivot groove 31 ', the width of this pivot groove 31 ' is greater than the thickness of buckle 4, when on the buckle 4/after the lower end embedded in this pivot groove 31 ', can make buckle 4 was fulcrum with pivot groove 31 ', left and right swing in the inner chamber of door bolt column base 3 ', tilt to intersect with sliding part 6, realize the clip effect.So, buckle 4 needn't be provided with pivot 41 again, so that make and avoid because of pivot 41 fracture failure.In addition, the back sides that door bolt column base 3 opens wide can be provided with a cover plate, and are in addition fastening with screw.
