Abstract
The utility model discloses a contraction structure for the music stand stabilizer, which should be connected reliably and stably, hard to be damaged and can improve the beautiful effect of the integral shape. Therefore, a long groove is arranged the connecting part between the inner side wall of the tubular stabilizer and the horizontal bracing. The connecting part between the horizontal bracing and the stabilizer bends downward into a structure of two sections, of which the front section main axis is parallel or superposition with the main axis of the tubular stabilizer. The front section of the connecting part of the horizontal bracing inserts into the tubular stabilizer through the long groove, and is hinged with the two side walls of the corresponding tubular stabilizer.
Description
Technical field
The utility model relates to the music easel technical field, particularly a kind of retracting structure of music easel feet.
Background technology
Existing music easel generally is made up of music score supporting plate, connection tube head, inner bracing piece, outer support bar, locking knob, music easel pin etc., the activity threeway that is sleeved on outer support bar middle and lower part is hinged with the tubular support pin upper end that three isosceles triangles are arranged respectively, outer support bar bottom is set with fixedly threeway, the outside, every tubular support pin middle part with fixedly be hinged with flat or tubular stull between the threeway, the retracting structure of formation music easel feet.Above-mentioned retracting structure has the following disadvantages: because stull is hinged at the tubular support outside of foot, this syndeton is firm inadequately, the damage of easily becoming flexible, get loose (1).(2) diminish the moulded effect of product.
Summary of the invention
The purpose of this utility model be to provide a kind of connect reliable, firm, be difficult to get loose and damage and the retracting structure of moulded music easel feet attractive in appearance.
The technical solution that the utility model proposed is such: a kind of retracting structure of music easel feet, comprise music score supporting plate 1, inner bracing piece 2, outer support bar 3, connect tube head, locking knob, the activity threeway 4 that is sleeved on outer support bar 3 middle and lower parts is hinged with tubular support pin 5 upper ends that three isosceles triangles are arranged respectively, outer support bar 3 bottoms are set with fixedly threeway 6, every tubular support pin 5 middle parts and fixedly be hinged with stull 7 between the threeway 4, on tubular support pin 5 madial walls, have a rectangular groove 8 with stull 7 joints, stull 7 is bent into two-stage structure downwards with the connecting portion 7-1 that feet 5 joins, or the coincidence parallel of its leading portion axis with tubular support pin 5 axis that connected, described stull 7 connecting portion 7-1 leading portions pass elongate slots 8 and insert in the tubular support pin 5, and its leading section is hinged with corresponding tubular support pin 5 two sides.
Compared with prior art, the utlity model has following beneficial effect:
(1) because stull is hinged in the tubular support pin, the rectangular groove of opening in tubular support pin inboard provides sufficient space for folding between this stull and the feet, simultaneously, this rectangular groove has been done appropriate restriction to the movement locus of stull again, therefore the retracting structure of this music easel feet reasonable in design, connect reliable, firm, free folding and unfolding is difficult to damage.
(2) because stull and feet adopt built-in articulated structure, improved moulded aesthetic.
The utility model is mainly used in the retracting mechanism of music easel feet.
Description of drawings
Fig. 1 is the retracting structure schematic diagram of a kind of music easel feet of present embodiment.
The specific embodiment
By following embodiment the utility model is further elaborated.
Referring to shown in Figure 1, a kind of retracting structure of music easel feet, this music easel is made up of music score supporting plate 1, inner bracing piece 2, outer support bar 3, a plurality of connection tube head and locking knob, feet and retracting structure thereof.Outer support bar 3 is enclosed within on the inner bracing piece 2, regulates and fastening its mutual alignment by connecting tube head and locking knob.Music score supporting plate 1 is inclined in inner bracing piece 2 upper tops by horizontal support, connection tube head and locking knob.
The activity threeway 4 that is sleeved on outer support bar 3 middle and lower parts is thereon fastening by locking knob, three tubular support pin 5 upper ends are hinged with activity threeway 4 respectively, outer support bar 3 bottoms are set with fixedly threeway 6, every tubular support pin 5 middle parts and fixedly be hinged with stull 7 between the threeway 4, on tubular support pin 5 madial walls, have a rectangular groove 8 with stull 7 joints, the stull 7 connecting portion 7-1 that join with feet 5 are bent into two-stage structure downwards, or the coincidence parallel with the axis of the tubular support pin 5 that is connected of its leading portion axis, these stull 7 connecting portion 7-1 leading portions are passed elongate slots 8 and are inserted in the tubular support pin 5 hinged with its two side.When feet folded, stull connecting portion 7-1 along rectangular groove 8 activities freely.
