Description
Technical field
The utility model 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 storage of folding rear toilet supporting construction, is widely used in usually used as support frame structure in the device that the needs such as qin frame, Collapsible type desk frame or folding seat take and receive.
It is a kind of electronic musical instrument frame support structure of the utility model bulletin of 201020026750.3 as China Patent No., it adopts the body of rod being arranged to by the second support bar be 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 the adjustment more convenient and quicker of height; This device is by location-plate is arranged to sector structure, serrate slot is set in sector structure simultaneously, the angular dimension regulating the first support bar and the second support bar to interlock when launching is coordinated by keeper and serrate slot, thus adjustment whole height, when two support bars fold, block fixing by keeper and serrate slot; But two support bars launch or when folding, all need repeatable operation keeper to reach corresponding function, and once Primary regulation height is 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 problem to be solved in the utility model is to provide a kind of simple operation, x type folding rack highly easy to adjust.
The utility model 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 and the second described support bar assembly are coupling by bearing pin, 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 be 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 the second described 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, the limited block that can slide along described arc sliding groove is provided with in described arc sliding groove, described limited block is 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 also can slide along described arc-shaped limit groove, the end of described adjustment pin is provided with for regulating and fixing the locating device of the described position of 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 coordinated with described screw, described adjustment pin is successively through described arc regulating tank and pad and the end of described adjustment pin is screwed onto in described screw, between one end that described pad is crimped on described backstay and the first described rotating disk, the other end of described backstay is provided with the dwang for rotating described backstay.When regulating limited block, unscrew backstay and adjustment pin, now arrange the position of adjustment pin in arc regulating tank by dwang, 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 pad is pressed on the first rotating disk by backstay, and limited block is located by adjustment pin.
Described shaft collar projection is provided with elastomer block, the second described rotating disk is provided with the cavity for holding 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 is 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 less likely to occur to relatively rotate, safer when storage and carrying; When the first support bar assembly and the second described support bar assembly relatively rotate, elastomer block is subject to the extruding of the second rotating disk and is in elastic compression, elastomer block produces certain resistance owing to there is elastic deformation to the second rotating disk, first support bar assembly and the second support bar assembly can not be launched rapidly when not having applied external force, avoiding when children use because of not fully promptly or surprisingly unclamp the first support bar assembly and the second support bar assembly and work the mischief to self or other people.
The first described rotating disk being provided with for indicating the indicating gauge regulating height or adjusting angle, described pad being provided with the indication piece being used in reference to particular location on described indicating gauge.User can with reference to the position of indication piece indication on indicating gauge when regulating whole height, therefore very convenient to the adjustment of whole height.
The first described rotating disk is provided with the first oval hole, the second described rotating disk is provided with the second oval hole, the first described support bar assembly is welded on the first described rotating disk, the first described support bar assembly and the pad of the first described rotating disk are positioned on the first described oval hole, the second described support bar assembly is welded on the second described rotating disk, and the second described support bar assembly and the pad of the second described rotating disk are 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, decreases the wearing and tearing of butt welding contact, and pad is blocked by the first support bar assembly and the second support bar assembly, adds aesthetic property.
Compared with prior art, when the utility model has the advantage of the use height regulating 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 located by adjustment pin, when the first support bar assembly and the second support bar assembly relatively rotate, spacer pin slides in slip stopper slot, when spacer pin slides into the end in slip stopper slot, the first support bar assembly and the second support bar assembly stop relatively rotating, and now x type folding rack is in the normal operating condition launched completely; When needs regulate use height again, only need after gathering x type folding rack, by locating device limited block be adjusted to suitable position and locate, when again launching x type folding rack, x type folding rack is in the complete deployed condition after again regulating height; Without the need to operating in addition keeper during gathering x type folding rack, therefore use and regulate all very convenient.
