Description

Tape-replaceable box type cassette box

At present, both at home and abroad cassette storing case is five-point type screw location, not for tape change provide can be just project organization.Can not arbitrarily open the replacing tape in the ordinary course of things, this is because after opening several times, except the slit of thread abrasion, tape shell increases, influences the tonequality, open at every turn, barricade and pressing plate all are easy to come off in tape cassete, especially tape strand band is opened when tape cassete is suitable to be with, and this situation is more outstanding.In addition, from economic, practical angle, general tape must dispose a tape cassete, and concerning manufacturer, the utilization factor of tape is low, the waste starting material; Concerning the consumer, the buying expenses height is deposited inconvenience (the space occupancy volume is big), particularly to middle and primary schools, if buy a cover English tape, spend a lot of money,, so only need buy the tape that a cover has disk and get final product if the interchangeable tape cassete of a box tape is arranged.Like this, promptly save money, deposit and make things convenient for.

The utility model purpose: it is interchangeable to design a kind of tape, opens cassette storing case easily.

The utility model technical solution: the part that will have barricade and pressing plate junction, protrusion now changes into recessed, a pressing plate fixed groove has both respectively been arranged, so that pressing plate is fixed in the groove on the barricade both sides.For barricade and pressing plate are not come off after uncapping, a barricade fixed pin is arranged in the barricade middle part, the fixed pin of barricade rear side inserts in the barricade locating slot in the location key seat (with the lower casing consubstantiality) like this, and the guide pole of the pressing plate fixed groove end face of barricade front side and existing tape cassete is identical.After lid was opened like this, barricade and pressing plate can not come off.Unlatching tape cassete for convenience, the opening structure of the utility model setting is: by exposing the switch in the tape cassete outside, about stir, spring in the compression switch box, make and the switch slide block of switch consubstantiality also move left and right, a protruding tongue of the switch outside the extensible switch enclosure is arranged at switch slide block one end.The protruding tongue of this switch by stirring of switch, can enter or withdraw from the lock slots in the straight pin, and this straight pin is fixed on again on the location key seat (with the lower cover consubstantiality).Therefore, by stirring of switch, the protruding tongue of mobile switch just can be opened tape cassete easily.

The utility model advantage: it is convenient to open.Open back, barricade and pressing plate difficult drop-off.Main be do not influence under the former magnetic holder performance situation tape interchangeable, can realize that a box is with more, save starting material, reduce cost, it is convenient to store, and with 5 original fixed hinge-types that change into, is welcomed by users.

Below in conjunction with description of drawings the utility model most preferred embodiment.
