Abstract
The utility model relates to an automatic restoration co-opening lock of a music instrument case. The utility model adopts the structure that a plurality of lock catches are positioned at the edge of a case cover at intervals, the edge of a case body corresponding to the lock catches is axially provided with a plurality of lock bolt rods which are connected into a whole by a transmission line, one end of the transmission line is connected to an opening and closing rod of an opening and closing button, and each of the lock bolt rods is provided with a restoration spring which restores the lock bolt rod, or a transmission line pull spring which restores each of the lock bolt rods is arranged on the transmission line. The utility model can be used for simultaneously opening and closing the lock catches and automatically restoring each of the lock catches, and has the advantages of simple structure, easy use and good effect.
Description
Technical field
The utility model belongs to a kind of acoustic flat that automatically resets unblanks altogether.
Background technology
Traditional acoustic flat is made up of lid and box body, and lid is connected with hinge in the rear end with box body, then establishes several snap closes at other edge and is used for the folding lid, musical instrument is big more, and box body is big more, and snap close is many more, when opening lid, must open each snap close one by one, time-consuming hard.Also need several snap closes for bigger box body, still have the deficiency of using trouble.
Summary of the invention
Therefore, the purpose of this utility model is that a kind of acoustic flat that automatically resets of design is unblanked altogether, it is had can open and close the function of several snap closes simultaneously, and each snap close can be automatically reset, and simple in structure, easy to use, use cost is low and effective.For this reason, the utility model adopts and is located at interval on the lid edge at a plurality of snap closes, axle is provided with a plurality of dead bolt bars on the box body edge corresponding with a plurality of snap closes, each dead bolt bar is concatenated into one by a drive line, one end of drive line is connected on the folding bar of folding button, each dead bolt bar is provided with and makes its back-moving spring that resets, or is provided with the drive line extension spring that each dead bolt bar is resetted on drive line.The said structure design has reached the purpose of this utility model.
The utility model has the advantages that to open and close several snap closes simultaneously, and each snap close can be automatically reset, and simple in structure, easy to use, use cost is low and effective.

Specific embodiments
As shown in Figures 1 to 4, a kind of acoustic flat that automatically resets is unblanked altogether, is made up of lid 1, box body 2 and snap close 4.A plurality of (being generally more than 3) snap close is located at interval on the lid edge, and snap close is fixed by hold-down screw 10 and lid edge.Axle is provided with a plurality of dead bolt bars 5 on the box body edge of a plurality of snap close correspondences, and dead bolt bar lower end is coupling by stud shaft 8 and box body edge, and the grab dogging of dead bolt bar upper end fastens both doggings on the grab of the snap close of correspondence, is used to open and close box body and lid.Each dead bolt bar is concatenated into one by a drive line 13, and an end of drive line is connected on the folding bar 7 of folding button 3, and folding button axle is located on the box body, and folding bar and folding button the inner are affixed, rotates the folding button and can drive the rotation of folding bar simultaneously.Drive line is a wire, and for making things convenient for trend and the transmission of drive line at the box body edge, drive line should be set in the guiding pipe box 6, and guiding pipe box and box body edge are fixed, and drive line is each dead bolt bar of transmission in the guiding pipe box.
As shown in Figure 2, each dead bolt bar is provided with and makes its back-moving spring that resets 9, or is provided with the drive line extension spring 14 that each dead bolt bar is resetted on drive line.One end of described back-moving spring is fastened on the box body, and the other end of back-moving spring is fastened on the dead bolt bar.Each back-moving spring do the time spent, when rotation folding button drives the rotation of folding bar simultaneously, the folding bar spurs each dead bolt bar upper end by drive line and moves and the disengaging of snap close grab, thereby unlatching lid, unclamp close button then each back-moving spring each dead bolt bar is resetted, think that lid is fastened on the box body again to prepare.
As shown in Figure 4, obviously, described drive line extension spring one end is fastened on the box body, and the other end of back-moving spring is fixed on the drive line.This more simple structure also can make each dead bolt bar automatically reset, when rotation folding button drives the rotation of folding bar simultaneously, the folding bar spurs each dead bolt bar upper end by drive line and moves and the disengaging of snap close grab, thereby unlatching lid, the drive line extension spring is upheld, unclamp close button then the drive line extension spring shrink to drive drive line and spur each dead bolt bar upper end each dead bolt bar is resetted, think that lid is fastened on the box body again to prepare.
As shown in Figure 3, the folding of described dead bolt bar is to affixed reseting pressuring spring 11 1 ends, and the other end of reseting pressuring spring is fastened on the pressure spring plate 12 that fuses with box body.Obviously reseting pressuring spring is identical with the effect of back-moving spring, so be not repeated.
During use, when rotation folding button drove the rotation of folding bar simultaneously, the folding bar spurred each dead bolt bar upper end by drive line and moves and the disengaging of snap close grab, thus the unlatching lid, unclamp close button then each back-moving spring each dead bolt bar is resetted, think that lid is fastened on the box body again to prepare.
In a word, the utility model can open and close snap close simultaneously, and each snap close is automatically reset, and simple in structure, easy to use, and use cost is low and effective.
