Embodiment
Understand technology contents of the present utility model for convenience of those skilled in the art, below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figures 1 to 3, the Foldable musical instrument rack that this case provides comprises: turning joint part 2, be connected to the expansion link 6 of turning joint part by rotation axis 12, expansion link 6 inside comprise slide guide device, be connected to the scalable leg 1 of turning joint by rotation axis 12, be installed on the nut 3 on turning joint part 2 by pin-and-hole 24.
The first embodiment
As shown in Figure 4, the inner slide guide device of expansion link comprises and is arranged at the axial fin 9a of outer tube 7 inwalls and is equipped with in the gathering sill 10a of inner tube 8 outer walls for the outer tube of this embodiment expansion link and inner tube fit structure.Fin 9a extends to apart from outer tube and connects turning joint 2 end 2-10cm from the free end of outer tube, corresponding, described gathering sill 10a extends axially 1-5cm from the free end of inner tube.By the slide guide device of expansion link, in the time that expansion link pulls open, fin is directed to groove restriction, and inner and outer tubes can not be rotated each other, and four of qin frame legs can not relatively rotate around the axis of expansion link after opening, and the stability of qin frame significantly improves.When expansion link shortens to the most in short-term, the close turning joint end that gathering sill is in outer tube does not arrange fin place, fin and gathering sill lift restrictions, between the inner and outer tubes of expansion link, can mutually rotate, two pairs of the left and right leg of qin frame can be folded in respectively the both sides of expansion link like this, and expansion link is in the centre of four legs, and qin frame like this is folded up rear four legs and can mutually do not collided with and cause falling paint even to damage, volume after making qin frame folding is less, is more convenient for carrying or transporting.
The second embodiment
As shown in Figure 5, the inner slide guide device of expansion link comprises and is arranged at the axial gathering sill 10b of outer tube 7 inwalls and is equipped with the fin 9b in outer wall of inner tube 8 for the outer tube of this embodiment expansion link and inner tube fit structure.Described fin 9b extends to apart from outer tube and connects turning joint 2 end 2-10cm from the free end of inner tube, corresponding, described gathering sill 10b extends axially 1-5cm from the free end of outer tube.By the slide guide device of expansion link, in the time that expansion link pulls open, fin is directed to groove restriction, and inner and outer tubes can not be rotated each other, and four of qin frame legs can not relatively rotate around the axis of expansion link after opening, and the stability of qin frame significantly improves.When expansion link shortens to the most in short-term, fin is not directed to groove restriction, the close turning joint end that fin on outer wall of inner tube is in outer tube does not arrange gathering sill part, fin is removed the restriction with gathering sill, now between the inner and outer tubes of expansion link, can mutually rotate, two pairs of the left and right leg of qin frame can be folded in respectively the both sides of expansion link like this, expansion link is in the centre of four legs, qin frame like this is folded up rear four legs and can mutually do not collided with and cause falling paint even to damage, volume after making qin frame folding is less, is more convenient for carrying or transporting.
By outer tube 7 ends, free skating moved end at expansion link, the block piece that restriction inner tube 8 skids off is set, makes inner tube can not pull out outer tube.
The free end of outer tube 7 is socketed with locking device 4, makes the connection of inner and outer tubes more firm.
Described scalable leg is that two or many loop bars are socketed to form, the outer cover of loop bar and loop bar junction is connected to locking device 4, each turning joint part connects two legs by rotating shaft and is splayed separately, by the socket of many loop bars, bearing height can freely be selected, and splayed is supported on the mode on ground, to form plane triangle structure be stable structure in planar structure.
As Fig. 6, described locking device 4 comprises that a lock ring, in the lasso 16 of outer tube end, is provided with elasticity bolt 17 in the indentation, there of lasso, and bolt one end is interspersed in lasso by nut, the other end is provided with degree of tightness handle 18 by movable axis, and described locking device is locked or unclamped all very convenient.
Described turning joint part is respectively arranged with the limited step 15 of limiting rod, the relative turning joint part of leg expanded angle on connecting portion, be respectively arranged with vertical links, leg axle center in connecting rod, leg relevant position and limit step the card-bit part 5 coordinating, card-bit part activity is interspersed in expansion link, leg, makes the opening angle of leg be convenient to regulate and be limited in 60 ° of angular ranges.
Described nut 3 upper ends are fixed with the soft bolster of one deck and can protect the lower end of qin not by mill flower; the friction factor of soft bolster is large; also make the placement of qin more firm; the lower end of nut is provided with the latch perpendicular to lower surface; be connected with the pin-and-hole 13 on turning joint part 2, installation or removal are easy.
One of described nut is dull and stereotyped, and another root is provided with disciform groove, is convenient to the stable wild goose foot of placing seven-stringed plucked instrument in some ways similar to the zither.
Above-described embodiment is only wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
