Description
Technical field
The present invention relates to a kind of supporting structure, especially a kind of x type folding rack.
Background technology
X type folding rack is due to its height flexible adjustment, and the taking in of folding rear toilet supporting construction is widely used in device that qin frame, Collapsible type desk frame or folding seat etc. need to take and take in usually used as support frame structure.
As a kind of electronic musical instrument frame support structure of the China Patent No. utility model bulletin that is 201020026750.3, it adopts is arranged to by the second support bar the body of rod being formed by connecting by location-plate by the upper body of rod and the lower body of rod, and this body of rod is hinged in same plane by location-plate and the first support bar, make the folding of qin frame and use adjusting more convenient and quicker highly; This device is by location-plate is arranged to sector structure, serrate slot is set simultaneously in sector structure, angular dimension while launching by regulating keeper and coordinating of serrate slot the first support bar and the second support bar to interlock, thereby adjusting whole height, when two support bars fold, by keeper and serrate slot, block fixing; Yet, when two support bars launch or fold, all need repeatable operation keeper to reach corresponding function, once and Primary regulation height not in place, also need multi-pass operations keeper that qin frame height is adjusted to suitable position, it is convenient not to operate.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of simple operation, x type folding rack highly easy to adjust.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of x type folding rack, comprise the first support bar assembly and the second support bar assembly, together with the first described support bar assembly is coupling by bearing pin with the second described support bar assembly, the position that is coupling of the first described support bar assembly and the second described support bar assembly is provided with arrangement for adjusting height, described arrangement for adjusting height comprises the first rotating disk being fixedly mounted on the first described support bar assembly, be fixedly mounted on the second rotating disk on the second described support bar assembly and the shaft collar between the first described rotating disk and described the second rotating disk, described shaft collar is fixedly connected with the first described rotating disk, described bearing pin is through the first described rotating disk, described shaft collar and the second described rotating disk, described shaft collar is provided with arc sliding groove along the circumferential direction, the first described rotating disk is provided with arc regulating tank along the circumferential direction, the second described rotating disk is provided with arc-shaped limit groove along the circumferential direction, in described arc sliding groove, be provided with the limited block that can slide along described arc sliding groove, on described limited block, be fixedly installed adjustment pin and spacer pin, described adjustment pin also can be slided along described arc regulating tank through described arc regulating tank, described spacer pin stretches in described arc-shaped limit groove and can slide along described arc-shaped limit groove, the end of described adjustment pin is provided with for regulating and fix the locating device of the position of described adjustment pin on the first described rotating disk.
Described locating device comprises backstay and pad, one end of described backstay is provided with screw, the end of described adjustment pin is provided with the screw thread coordinating with described screw, described adjustment pin is screwed onto in described screw through the end of described arc regulating tank and pad and described adjustment pin successively, between one end of backstay described in described pad is crimped on and the first described rotating disk, the other end of described backstay is provided with for rotating the dwang of described backstay.While regulating limited block, by dwang, unscrew backstay and adjustment pin, the position of adjustment pin in arc regulating tank is now set, adjustment pin drives limited block to slide in arc sliding groove; When being adjusted to correct position, by dwang screwed in place bar and adjustment pin, now the pad bar that is positioned is pressed on the first rotating disk, and limited block is positioned by adjustment pin.
Described shaft collar projection is provided with elastomer block, on the second described rotating disk, be provided with for holding the cavity of described elastomer block, the elastomer block described in when the first described support bar assembly and the second described support bar assembly draw in is completely in extended configuration and be contained in described cavity.When the first support bar assembly and the second support bar assembly draw in completely, because elastomer block is contained in cavity, the first support bar assembly and the second support bar assembly are not easy to relatively rotate, safer when taking in and carrying; When the first support bar assembly and the second described support bar assembly relatively rotate, elastomer block be subject to the second rotating disk extruding and in elastic compression, elastomer block produces certain resistance owing to there is elastic deformation to the second rotating disk, the first support bar assembly and the second support bar assembly can not launched rapidly when there is no applied external force, while having avoided children to use because of not fully promptly or surprisingly unclamp the first support bar assembly and the second support bar assembly works the mischief to self or other people.
On the first described rotating disk, be provided with the indicating gauge that regulates height or adjusting angle for indicating, on described pad, be provided with the indication piece being used in reference to particular location on described indicating gauge.User can be with reference to the position of indication piece indication on indicating gauge when regulating whole height, therefore very convenient to the adjusting of whole height.
On the first described rotating disk, be provided with the first oval hole, on the second described rotating disk, be provided with the second oval hole, the first described support bar assembly is welded on the first described rotating disk, the pad of the first described support bar assembly and the first described rotating disk is positioned on the first described oval hole, the second described support bar assembly is welded on the second described rotating disk, and the pad of the second described support bar assembly and the second described rotating disk is positioned on the second described oval hole.Pad is all positioned at the inside of the first support bar assembly and the second support bar assembly, has reduced the wearing and tearing of butt welding contact, and pad blocked by the first support bar assembly and the second support bar assembly, has increased aesthetic property.
Compared with prior art, while the invention has the advantages that the use height that regulates x type folding rack, unclamp locating device, now adjust the position of adjustment pin in arc regulating tank, adjustment pin drives limited block to slide in arc sliding groove; When being adjusted to correct position, by locating device, adjustment pin is fixed on the first rotating disk, now limited block is positioned by adjustment pin, when the first support bar assembly and the second support bar assembly relatively rotate, spacer pin slides in slip stopper slot, during end in spacer pin slides into slip stopper slot, the first support bar assembly and the second support bar assembly stop relatively rotating, now the normal operating condition of x type folding rack in launching completely; When needs regulate use height again, only need be after drawing x type folding rack in, by locating device, limited block is adjusted to suitable position location, while again launching x type folding rack, x type folding rack is in again regulating the complete deployed condition after height; While drawing x type folding rack in, without keeper is operated in addition, therefore use and regulate all very convenient.
