Description
Technical field
The invention belongs to a kind of telescopic adjustment cross bar, be used for the realm of building construction.
Background technology
Normally used support system and scaffold mostly are the support system or the scaffold of fastener type steel pipe formula, multi-function door type frame type, independent steel strut formula, bowl button-type greatly in the building operations, the also useful lumps of wood is made stressed support system, makes support system or scaffold with aluminium wire colligation mao bamboon or round log (husky bar).These support systems or scaffold are deposited not only and to be had that to expend the raw material amount bigger, heavy, carry installation, construction labour intensity is big, the construction effort is time-consuming, efficiency of construction is low and speed is slow, complex structure, the cost height, damage easily and the not good shortcoming of stressed effect, also exist and to regulate supporter plane of structure shape with the need, for example: when the plane of structure shape need of supporter is polygon or abnormity, also must make the cross bar of special-shaped segment length as required in addition, and abnormity section cross bar is once making, then length can not be regulated on demand at any time, makes operating procedure wayward, bring certain trouble to construction safety.After particularly support system is set up, can't adjust the length of each cross bar at any time as required, thus except that make support system not firm or outside the injustice, also cause engineering face injustice, the serious engineering that also makes is scrapped.
Summary of the invention
The objective of the invention is to design a kind of telescopic adjustment cross bar, can adjust the length of each cross bar at any time as required, but make supporter plane of structure shape regulated at will, have easy to use, operation effect height is time saving and energy saving, safe and reliable, highly versatile, the accessory standard, working specification, technological standards easily reaches, be convenient to check the advantage that is easy to mount and dismount.
For this reason, it is tubular rod that the present invention adopts loop bar and inserted link, inserted link one end is plugged in the loop bar from loop bar one end, the loop bar periphery wall is provided with one section external thread part, suitable loop bar length is to being provided with the guide groove that connects loop bar on the external thread part, spiral shell is established adjusting knob on the external thread part, and spacing distance is provided with the adjusting pin-and-hole that connects inserted link on the inserted link, and pin inserts two on the inserted link and regulates the fixedly adjusting knob two ends of inserted link on loop bar of pin-and-hole outside the guide groove that is positioned at the adjusting knob two side ends.The said structure design has reached purpose of the present invention.
Advantage of the present invention is to adjust the length of each support rail at any time as required, but makes supporter plane of structure shape regulated at will, has assembling flexibly, be easy to installing/dismounting, prop up and take conveniently, adapt to wide, time saving and energy saving, easy and simple to handle, the workman grasps easily, is convenient to check, but the inserted link usage measure is arranged, construction safety is reliable, the advantage that result of use is good.

The specific embodiment
To shown in Figure 8, a kind of telescopic adjustment cross bar is mainly by loop bar 2, inserted link 6 be positioned at loop bar and inserted link two ends and formed by the plug 1 that plug shaft 7 is coupling both as Fig. 1.
As shown in Figure 1 to Figure 3, loop bar and inserted link are tubular rod, and inserted link one end is plugged in the loop bar from loop bar one end.The loop bar periphery wall is provided with one section external thread part 3, and suitable loop bar length is to being provided with the guide groove 5 that connects loop bar on the external thread part.Spiral shell is established adjusting knob 8 on the external thread part.Spacing distance is provided with the adjusting pin-and-hole 11 that connects inserted link on the inserted link, and pin 4 inserts adjacent two on the inserted link and regulates the fixedly adjusting knob two ends of inserted link on loop bar of pin-and-hole outside the guide groove that is positioned at the adjusting knob two side ends.Then fixing from the pin head that the guide groove other end of loop bar passes with nut 12, prevent that pin breaks away from guide groove.
As Fig. 4 and shown in Figure 6, described plug one side is provided with grafting notch 14.The effect of plug be insert solid in the slot 17 of the socket 21 that is fixed as one with scaffold montant 16 and hold in spacing Kato 19 upper ends.Socket is made up of interior endless tube, the outer snap ring 18 of opening, is prior art, so be not repeated.The interior endless tube of every slot lower end is provided with spacing Kato 19, is convenient to plug and is inserted and secured in the slot of spacing Kato upper end from every slot upper end.Described loop bar and inserted link two ends are provided with the grafting tongue 13 corresponding with the notch of pegging graft.Plug is coupling by plug shaft 7 and inserted link and loop bar two ends, is beneficial to plug and socket and pegs graft.
As shown in Figure 5, described adjusting knob is provided with the handle 10 of this adjusting knob of rotation.Handle is coupling by axle 9 and adjusting knob, and the adjusting knob internal perisporium is provided with the internal thread part 15 that is spirally connected with external thread part.
The adjusting pin-and-hole that described guide groove one end from loop bar penetrates and passes on the inserted link is provided with nut 12 from the pin head that the guide groove other end passes.Prevent that pin breaks away from guide groove.
Described external thread part is positioned at loop bar periphery wall front portion, or the middle part.Can and be convenient to rotate adjusting knob setting according to loop bar length.The width of the described adjacent two hole back gauges of regulating pin-and-holes and adjusting knob is identical or greater than the width 1-5mm of adjusting knob.
As shown in Figure 7 and Figure 8, during use, the present invention is as cross bar horizontal in support system and the scaffold 20, only needs the plug at two ends of the present invention is inserted the slot that is positioned at each socket on the montant, can finish scaffold and build.When adjusting scaffold plane of structure shape or horizontal length as need of work, only need turn handle to the anticlockwise adjusting knob, adjusting knob is moved to left-handed along the external thread part on the loop bar, drive simultaneously by the inserted link of pin jacking and also be moved to the left contraction cross bar length along guide groove at the adjusting knob two ends.Otherwise, then move to right elongation cross bar length.Finish and adjust scaffold plane of structure shape or horizontal length.The pitch width decision fine setting length of external thread part.
In a word, the present invention can adjust the length of each cross bar at any time as required, makes the supporter plane of structure shape can be random Regulate, assembling is easy to installing/dismounting flexibly, takes conveniently, adapt to wide, time saving and energy saving, easy and simple to handle, the workman Grasp easily, be convenient to check that construction safety is reliable, the advantage that result of use is good can be promoted the use of.
