A kind of x types folding rack
Technical field
The present invention relates to a kind of supporting structure, especially a kind of x types folding rack.
Background technology
X types folding rack folds the storage of rear toilet supporting construction, usually as support due to its height flexible adjustment
Frame structure be widely used in qin frame, Collapsible type desk frame or folding seat etc. need to take and the device received in.
Such as China Patent No. is a kind of electronic musical instrument frame support structure of 201020026750.3 utility model bulletin, its
Using the body of rod for being arranged to be formed by connecting by location-plate by the upper body of rod and the lower body of rod by second support bar, and pass through the body of rod
Location-plate and first support bar are hinged in approximately the same plane, make the folding of qin frame and the regulation more convenient and quicker using height;
The device is by location-plate is arranged to sector structure, while serrate slot is arranged in sector structure, by keeper and tooth
The cooperation of shape groove adjusts the angular dimension that first support bar and second support bar are interlocked when launching, so as to adjust whole height, when
When two support bars are folded, fixation is blocked by keeper and serrate slot;However, when two support bars launch or fold, being required to anti-
Keeper is operated again reaching corresponding function, once and Primary regulation is highly not in place, in addition it is also necessary to multi-pass operation keeper comes
Qin frame is highly adjusted to into suitable position, it is not convenient enough to operate.
The content of the invention
The technical problem to be solved is to provide a kind of simple operation, x type folding racks highly easy to adjust.
The present invention solve the technical scheme that adopted of above-mentioned technical problem for:A kind of x types folding rack, including the first support
Bar assembly and second support bar component, described first support bar component and described second support bar component are connect by bearing pin axle
Together, the axis part position of described first support bar component and described second support bar component is provided with height and adjusts dress
Put, described arrangement for adjusting height includes the first rotating disk, the fixed installation being fixedly mounted on described first support bar component
In the second rotating disk on described second support bar component and between the first described rotating disk and the second described rotating disk
Fixed disk, described fixed disk are fixedly connected with the first described rotating disk, and described bearing pin is through the first described rotating disk, described
Fixed disk and the second described rotating disk, described fixed disk is provided with arc sliding groove along the circumferential direction, described first
Rotating disk is provided with arc regulating tank along the circumferential direction, and the second described rotating disk is provided with arc-shaped limit groove along the circumferential direction,
The limited block that can be slided along described arc sliding groove is provided with described arc sliding groove, fixation on described limited block sets
Adjustment pin and spacer pin are equipped with, described adjustment pin passes through described arc regulating tank and can slide along described arc regulating tank
Dynamic, described spacer pin is stretched in described arc-shaped limit groove and can be slided along described arc-shaped limit groove, described adjustment pin
End be provided with for adjust and position of the fixed described adjustment pin on the first described rotating disk positioner.
Described positioner includes locating rod and pad, and one end of described locating rod is provided with screw, described tune
The end of section pin is provided with the screw thread coordinated with described screw, described adjustment pin sequentially pass through described arc regulating tank and
The end of pad and described adjustment pin is screwed onto in described screw, and described pad is crimped on one end of described locating rod
And between the first described rotating disk, the other end of described locating rod is provided with for rotating the rotating bar of described locating rod.
When adjusting limited block, locating rod and adjustment pin are unscrewed by rotating bar, position of the adjustment pin in arc regulating tank are now set,
Adjustment pin drives limited block to slide in arc sliding groove;When adjust to correct position when, by rotating bar screwed in place bar with
Adjustment pin, now pad be positioned bar and be pressed on the first rotating disk, limited block is positioned by adjustment pin.
On described fixed disk, projection is provided with elastomer block, is provided with for accommodating described bullet on the second described rotating disk
The cavity of property block, the elastomer block described in when described first support bar component and described second support bar component are drawn in completely
In extended configuration and it is contained in described cavity.When first support bar component and second support bar component are drawn in completely,
As elastomer block is contained in cavity, first support bar component and second support bar component are less likely to occur to relatively rotate, storage
And carry when it is safer;When first support bar component and described second support bar component are relatively rotated, elastomer block is subject to
The extruding of the second rotating disk and be in elastic compression, elastomer block due to occur elastic deformation and to the second rotating disk produce it is certain
Resistance, make first support bar component and second support bar component not to launch rapidly in no applied external force, it is to avoid youngster
It is virgin when using because fully promptly or not being accidentally unlocked first support bar component and second support bar component and artificial to itself or he
Into harm.
It is provided with the first described rotating disk for indicating the dial gauge for adjusting height or adjusting angle, on described pad
It is provided with for pointing to the indication piece of particular location on described dial gauge.User refers to indicate when whole height is adjusted
The position of part indication on dial gauge, thus it is very convenient to the regulation of whole height.
The first waist round hole is provided with the first described rotating disk, the second waist round hole, institute on the second described rotating disk, is provided with
The first support bar components welding stated on the first described rotating disk, described first support bar component and the first described rotating disk
Pad be located at the first described waist round hole on, described second support bar components welding on the second described rotating disk, institute
The second support bar component stated is located in the second described waist round hole with the pad of the second described rotating disk.Pad is respectively positioned on
The inside of first support bar component and second support bar component, reduces the abrasion of butt welding contact, and pad by first
Strut component and second support bar component are blocked, and increased aesthetic property.
Compared with prior art, it is an advantage of the current invention that when adjusting the use height of x type folding racks, unclamping positioning dress
Put, now adjust position of the adjustment pin in arc regulating tank, adjustment pin drives limited block to slide in arc sliding groove;Work as tune
When saving to correct position, adjustment pin is fixed on the first rotating disk by positioner, now limited block is determined by adjustment pin
Position, when first support bar component and second support bar component relatively rotate, spacer pin slides in slip stopper slot, when
When spacer pin slides into the end in slip stopper slot, first support bar component and second support bar component stop relatively rotating,
Now x types folding rack is in the normal operating condition being fully deployed;When needing to be adjusted using height again, need to only draw in
After x type folding racks, limited block is adjusted to by suitable position by positioner and is positioned, launch x type folding racks again
When x types folding racks in adjusting its fully unfolded position after height again;Without the need for keeper during gathering x type folding racks
Operated in addition, therefore used and regulation is quite convenient to.
