Specific embodiment

The utility model provides a kind of disk stationary fixture, to make the purpose of this utility model, technical solution and effect more Add clear, clear, the utility model is further described as follows in conjunction with drawings and embodiments.It should be appreciated that this place The specific embodiment of description only to explain the utility model, is not used to limit the utility model.

Herein, the direction towards disk Pan Bi is referred to after, it is preceding to refer to backwards to the direction of disk Pan Bi.

Please refer to Fig. 1-4, a kind of disk stationary fixture, including shell 1, offer opening on rear side of shell, shell it is upper A Scroll 2 and a drive shaft 3 are vertically provided between lower wall, winding has band 4 on Scroll；One end of the band It is connected with Scroll, the other end is stretched out from the opening and is connected with rear；The upper end of drive shaft 3 passes through the upper wall of shell And it is provided with a driving gear 5, the upper end of Scroll 2 passes through the upper wall of shell and is provided with a driven gear 6, driving tooth Wheel and driven gear engagement；The upper end of drive shaft is provided with a rocking handle 7, and the upper surface of shell is provided with for locking driven tooth The locking mechanism 8 of wheel.

When carrying out the fixation of disk Pan Bi, the outer peripheral surface of Pan Bi is waled with band, is then shaken rocking handle driving Scroll and is turned It is dynamic, band is tightened, finally driven gear is locked with locking mechanism, prevents Scroll from rotating backward and loosen band.The disk is fixed Fixture can effectively fix each arc plate, prevent them to be displaced during glue is solid, and structure is simple, user Just, the fixation suitable for the wooden disk of different-diameter.

Specifically, seeing Fig. 1,2, the locking mechanism 8 includes the closing piece 8.1 of 6 circumferential surface of face driven gear, is fixed on shell The connecting plate 8.2 of 1 upper wall, and the screw rod 8.3 of connection closing piece and connecting plate；Closing piece towards the side of driven gear be with from The adaptable curved surface of moving gear circumferential surface, to being provided with the tooth 8.1a engaged with driven gear on curved surface；The screw rod is along driven tooth Wheel is arranged radially, and one end and closing piece are connected, and the other end, which is slideably worn, sets on connecting plate and be connected with a butterfly Nut 8.4 is arranged with a compressed spring 8.5 on screw rod, which offsets with closing piece, the other end and connecting plate phase It supports.

When locking, wing nut is turned, closing piece is made to press to driven gear and and driven gear under the action of compressed spring Engagement, driven gear can not rotate, to prevent band from loosening；When unlock, direction turns wing nut, and closing piece is made to leave compression Spring can carry out the winding of band.

Further, the opening is vertically provided with a first rotating shaft 9 and second shaft 10, the hoop One end of band is stretched out after opening around first rotating shaft 9 wears back around the second shaft 10 from opening, and is fixed on shell, such as Fig. 3 It is shown.It is offseted by first rotating shaft and the second shaft and band, band can be prevented in tightening and shell friction and be damaged.

In the present embodiment, a handle 11 is provided on the leading flank of the shell 1.It, can one when carrying out the folding and unfolding of band Hand handle holds handle, shakes rocking handle on the other hand, improves the convenience used.

Preferably, the diameter of the driving gear 5 is smaller than the diameter of driven gear 6, to improve output torque, to improve The tightening force of band.

In addition, the band 4 be as steel wire and nylon yarn braiding made of strap, the existing enough intensity of the band, With enough flexibilities, long-time service will not be elongated, avoids due to elongated in use process and loosens.

It is understood that for those of ordinary skills, can with technical solution according to the present utility model and The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement all should belong to the protection of the utility model Range.
