Description
Technical field
The present invention relates to a kind of qin shelf structure, especially a kind of folding qin frame.
Background technology
Existing folding qin frame often adopts X-type folding qin frame, X-type folding qin frame is generally mutually coupling by the first support bar and the second support bar and forms frame body, the height of X-type folding qin frame is regulated by rotating the first support bar and the second support bar, and by locating device, the height regulated is positioned, but often need first to unclamp locating device when regulating, after regulating the position of the first support bar and the second support bar, first prevent from continuing to relatively rotate with hand steered firmly the first support bar and the second support bar, regulating positioning device is fixed again, also need during gathering first to unclamp locating device, after drawing the first support bar and the second support bar in, prevent from unclamping with hand steered firmly the first support bar and the second support bar, regulating positioning device is fixed again, it is convenient not to operate, and once need repeatedly to regulate the height of X-type folding qin frame more to waste time and energy.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of height adjustment and draws folding qin frame easily and fast in.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of folding qin frame, comprise the first support bar and the second support bar that are mutually coupling, the first described support bar is fixedly installed the first rotating disk, the second described support bar is fixedly installed the second rotating disk, the second described rotating disk is fixedly installed shaft collar, described shaft collar is between the first described rotating disk 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 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, described adjustment pin is passed and is stretched out described arc regulating tank, wind spring is provided with in described shaft collar, described wind spring is provided with stiff end and elastic recovery end, the stiff end of described wind spring is fixedly connected with described shaft collar, described limited block is provided with slot, the elastic recovery end of described wind spring is embedded in described slot, described limited block is compressed the upper end abutting in described arc regulating tank by the elastic recovery end of described wind spring, the end of described adjustment pin is provided with locating device, described locating device is for straining described adjustment pin thus making described limited block compress the inside surface fitting in the first described rotating disk.
The inside surface of the first described rotating disk is provided with arc location teeth groove along the surrounding in described arc regulating tank direction, described limited block is provided with to locate with described arc that teeth groove matches one arrange arc and locate tooth bar.When locating device is located limited block, limited block be tightened up fit in the first rotating disk inside surface on, now arc location tooth bar be connected in arc location teeth groove in, limited block can not be slided, achieves better locating effect.
The second described rotating disk is provided with arc-shaped limit groove along the circumferential direction, described limited block is fixedly installed spacer pin, described spacer pin can slide along described arc-shaped limit groove, described spacer pin passes described arc-shaped limit groove and stretches out the second described rotating disk, the outer end of described spacer pin is fixedly installed gland, is provided with Compress Spring between described gland and the second described rotating disk.When unclamping locating device, Compress Spring promotes gland thus drives the limited block be fixedly connected with spacer pin, makes limited block no longer be close to the inside surface of the first rotating disk, thus convenient adjustment folds the height of qin frame or draws folding qin frame in.
Described locating device comprises locating sleeve with fixing threaded hole and pad, described adjustment pin is provided with the screw thread coordinated with described fixing threaded hole, the end of described adjustment pin is screwed onto in described fixing threaded hole, and described pad is crimped between described locating sleeve and the first described rotating disk.
Described shaft collar is provided with the scale mark being used to indicate and regulating height, the side of described pad is provided with the arrow be used in reference to described scale mark, described pad is provided with locating convex block, also can slide along described arc regulating tank in arc regulating tank described in described locating convex block embeds, described locating convex block is provided with arc limit, two location, match with a side of described arc regulating tank respectively and be adjacent in arc limit, location described in each, the thickness of described locating convex block is 0.7 ~ 0.9 times of the groove depth of described arc regulating tank.Locating convex block arcuately slides in regulating tank and can not rotate, and makes arrow point to the position at scale mark place all the time.
Described adjustment pin is provided with spacing screw, the sunken end face of described locating sleeve is provided with counterbore, limiting plate and caging bolt is provided with in described counterbore, described caging bolt comprises bolt head and screw rod, described limiting plate is provided with the through hole only allowing described screw rod to pass through, and described screw rod passes described through hole and is bolted in described spacing screw.The distance between adjusting bolt head and limiting plate is carried out by the position of rotating screw bolt in spacing screw, this distance is equaled or embeds the degree of depth in arc regulating tank close to locating convex block, thus when unclamping locating sleeve, because limiting plate is blocked by bolt head, pad can only move between locating sleeve and the first rotating disk, and amplitude of its motion is the distance between the bolt head that regulates and limiting plate just, therefore pad can not be deviate from arc regulating tank, finally makes arrow point to the position at scale mark place all the time.
Compared with prior art, the invention has the advantages that when unfolded qin frame, first support bar is equivalent to the second support bar and rotates, the locating device being in releasing orientation presses down by the first support bar, limited block slide downward in arc sliding groove is driven by adjustment pin, now limited block is subject to the elastic-restoring force of the elastic recovery end of wind spring, therefore the locating device in adjustment pin is close on the first support bar all the time, after regulating the height of folding qin frame to put in place, people only need to coordinate the elastic-restoring force of the elastic recovery end of wind spring to be buttressed by the first support bar, by regulating positioning device, limited block is positioned again, when needs partially or completely draw folding qin frame in, unclamp locating device, limited block is subject to the elastic-restoring force band dynamic positioning system upward sliding of the elastic recovery end of wind spring, thus driven the first support bar automatically to draw in towards the position at the second support bar place, launch or draw folding qin frame in and the operating process positioned is very convenient, time saving and energy saving.
