Abstract
A kind of active articulated telescopic frame, comprise some root posts and rhombus expansion bracket, rhombus expansion bracket by multipair arranged in a crossed manner, head and the tail mutually hinged connecting rod form, infall and the column of connecting rod are hinged, described rhombus expansion bracket is 2, arranges up and down in perpendicular, be connected with Synchronous pull rod between the interlinking lever end of 2 rhombus expansion bracket upper bottom portion, the hinge at the interlinking lever end place at rhombus expansion bracket top, below is projecting, this Synchronous pull rod bottom has the stopper slot that this hinge of confession slides up and down.The utility model by arranging gathering sill on Synchronous pull rod, the hinge of below can be fixed in groove movable, which define Synchronous pull rod and can not depart from i.e. allocation, not easily meet accident and topple over and be out of shape, compared to existing technology, more firm practical, avoid security incident, construct convenient, simultaneously with low cost, manufacture simple, so be worthy to be popularized.
Description
Technical field
The utility model relates to expansion bracket, particularly a kind of active articulated telescopic frame with guide-localization.
Background technology
The purposes of active expansion bracket widely, for the manufacture of retractable door, flexible fence etc., general expansion bracket uses to be needed to be connected with fixed traction part, feasible one-tenth rock-steady structure, but because existing design is reasonable not, accident can be toppled over because of the hidden danger of stability when using or carry, support body can be caused simultaneously to be out of shape, hingedly to come off, as shown in the figure, this makes troubles to daily production and application, needs to be improved.
Summary of the invention
The purpose of this utility model is: for the problems referred to above, provides a kind of active articulated telescopic frame of good stability.
For realizing above object, the technical solution adopted in the utility model is as follows: a kind of active articulated telescopic frame, comprise some root posts and rhombus expansion bracket, rhombus expansion bracket is by multipair arranged in a crossed manner, the connecting rod composition that head and the tail are mutually hinged, infall and the column of connecting rod are hinged, described rhombus expansion bracket is 2, arrange up and down in perpendicular, Synchronous pull rod is connected with between the interlinking lever end of 2 rhombus expansion bracket upper bottom portion, the hinge at the interlinking lever end place at rhombus expansion bracket top, below is projecting, this Synchronous pull rod bottom has the stopper slot that this hinge of confession slides up and down.
Further: stopper slot is hollow out or indent.
The utility model by arranging gathering sill on Synchronous pull rod, the hinge of below can be fixed in groove movable, which define Synchronous pull rod and can not depart from i.e. allocation, not easily meet accident and topple over and be out of shape, compared to existing technology, more firm practical, avoid security incident, construct convenient, simultaneously with low cost, manufacture simple, so be worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing of chute;
Number in the figure represents: 1-column; 2-Synchronous pull rod; 3-connecting rod; 4-chute; 5-hinge; 6-rhombus expansion bracket.
Detailed description of the invention
See Fig. 1, a kind of active articulated telescopic frame described in Fig. 2, often organize expansion bracket by two root posts 1, the rhombus expansion bracket 6 body formation that a Synchronous pull rod 2 is identical with two, two root posts 1 are the strip bars that length is equal, rhombus expansion bracket 6 forms by the steel bar shape connecting rod 3 that four length is identical is hinged, rhombus expansion bracket 6 can realize dilatation, on rhombus expansion bracket 6 support body, two jointed shafts of Arbitrary Relative are flexibly connected with two column 1 shaft screws respectively, upper and lower between two columns 1 is provided with above-mentioned two identical rhombus expansion brackets 6 altogether, rhombus expansion bracket 6 is positioned on same perpendicular, like this, drag wherein a root post 1 time, two rhombus expansion brackets 6 can realize synchronization telescope, described Synchronous pull rod 2 is strip rod members that length is less than column 1, the two ends of Synchronous pull rod 2 are articulated with on the hinge 5 of upper and lower two rhombus expansion brackets 6, require that this hinge 5 is not connected with column 1, concrete, interfered for anti-sliding stop and save cost, the termination, top of Synchronous pull rod 2 connects a hinge 5 bottom upper rhombus expansion bracket 6, is the stability of sliding, the bottom of Synchronous pull rod 2 connects with two relative hinges 5 of lower rhombus expansion bracket 6, and a hinge 5 is connected with termination, Synchronous pull rod 2 bottom.Another is hinged is connected with the shaft of Synchronous pull rod 2, namely Synchronous pull rod 2 is hinged with three rhombus expansion bracket 6 hinges 5.Like this two root posts 1, Synchronous pull rod 2 and two rhombus expansion brackets 6 are integrally connected, unobstructed for realizing slip, base oneself upon below at every root and roller is set.
Concrete, in order to realize the stability of expansion bracket movement, improve its structural strength, avoid toppling at slidingtype, the utility model is provided with limit sliding chutes 4 in Synchronous pull rod 2 shaft base section short transverse, in three hinges 5 be connected with Synchronous pull rod 2 in two above-mentioned rhombus expansion brackets 6, one hinge 5 at rhombus expansion bracket 6 top, lower end embeds in this stopper slot, this stopper slot is the hollow-out slot bore of bar shaped or the groove of depression, the closed at both ends of stopper slot, under stopper slot, blind end position is no more than the link position between lower rhombus expansion bracket 6 and two pin joints of column 1, the object of such setting is the mobile range limiting hinge 5 in this stopper slot, the hinge 5 i.e. mobile lower limit of Synchronous pull rod 2 is made to be no more than the line of lower rhombus expansion bracket 6 and column 1 pin joint, when avoiding by External Force Acting, there is non-unexpected deformation in expansion bracket.
The course of work of the present utility model is: general, expansion bracket by organizing said structure as combining and using more, during use, pull the column 1 of end, now launch expansion bracket, when not needing to use, namely reverse promotion realizes storage, by the stopper slot that the utility model is arranged, before and after when can avoid sliding, rod member such as column 1 grade is asynchronous.
Claims (2)
1. an active articulated telescopic frame, comprise some root posts and rhombus expansion bracket, rhombus expansion bracket by multipair arranged in a crossed manner, head and the tail mutually hinged connecting rod form, infall and the column of connecting rod are hinged, it is characterized in that: described rhombus expansion bracket is 2, arranges up and down in perpendicular, be connected with Synchronous pull rod between the interlinking lever end of 2 rhombus expansion bracket upper bottom portion, the hinge at the interlinking lever end place at rhombus expansion bracket top, below is projecting, this Synchronous pull rod bottom has the stopper slot that this hinge of confession slides up and down.
