Abstract
Provided is a buckled type loose-leaf binder. The buckled type loose-leaf binder comprises a circle-shaped portion and a base plate. The circle-shaped portion is formed by a left semi-circle-shaped portion and a right semi-circle-shaped portion, and the base plate can enable the circle-shaped portion to be fixedly installed on an envelope of a loose-leaf release. The left semi-circle-shaped portion is fixedly installed on the base plate, a rotation portion is arranged on the lower portion of the right semi-circle-shaped portion, rotation holes are formed in the rotation portion, and the rotation portion is hinged to the substrate through a rotation shaft. A locking part is further sleeved on the rotation shaft, the locking part can drive the rotation portion and the right semi-circle-shaped portion to rotate and is provided with a clamping buckle, and a buckled groove, matched with the clamping buckle, is formed in the position, corresponding to the position of the clamping buckle, of the substrate. The buckled type loose-leaf binder has the advantages of being novel in design, reasonable in structure, convenient to operate and safe in use due to adoption of a buckled type interlocking mode.
Description
Technical field
The utility model relates to and is used for the dismounting and the fixing loose-leaf binder of paper in a kind of loose-leaf notebook.
Background technology
Loose-leaf notebook is that a kind of loose-leaf binder that utilizes can be had convenient arrangement, use flexible characteristic its paper by the notebook of arbitrarily dismounting, replacing, adjustment.Be used for the dismounting and the fixing loose-leaf binder of paper in the loose-leaf notebook, thereby be that cast portion is installed on the strip of paper used for sealing of loose-leaf notebook by substrate by the opening and close the dismounting that can realize paper and fix of left half-turn shape portion in the cast portion and right half-turn shape portion.
Existing loose-leaf binder, but be left half-turn shape portion mostly and right half-turn shape portion forms the hinged relationship that certain angle rotates, and the deformation elastic force of slim steel disc self keeps left half-turn shape portion and right half-turn shape portion to open or closing state bottom it again.Operate this loose-leaf binder and make it open or close, often need bigger power, and the action of loose-leaf binder is comparatively stiff, cause not convenient, the easily puzzlement such as jam a finger of operation to the user.
Summary of the invention
The purpose of this utility model provides a kind of facility, button loose-leaf binder safe in utilization operated.
For achieving the above object, technical solution adopted in the utility model is: the button loose-leaf binder comprises the cast portion that is formed by left half-turn shape portion and right half-turn shape portion and cast portion can be installed in substrate on the loose-leaf notebook strip of paper used for sealing that left half-turn shape portion is installed in substrate; Right half-turn shape subordinate side is provided with the rotation section, and this rotation section is provided with rotation hole, forms hinged relationship by rotating shaft and substrate; Also be with in the described rotating shaft and can drive the lock piece that has buckle that rotate rotation section, right half-turn shape portion; The position of corresponding buckle is provided with the catching groove adaptive with buckle on the substrate.
Using method of the present utility model is: by rotating lock piece, drive right half-turn shape portion and rotate, thereby open or close cast portion, the dismounting that can realize paper is with fixing; Be buckled in the catching groove of substrate by buckle, can keep the closed condition of cast portion and be not opened easily lock piece.
The utility model can easily be realized opening and closing of cast portion by the operation lock piece, need not to operate energetically, also need not contact cast portion, has not only operated facility but also safe in utilization.
Further, consider that loose-leaf binder in actual use, be subject to the flat state of loose-leaf notebook, the rotational angle of right side half-turn shape portion generally is not more than 90 degree, if be the interlock of not free difference between lock piece and the right half-turn shape portion, then when cast portion is in open mode, lock piece is a good the centre that is positioned at left half-turn shape portion and right half-turn shape portion, will cause certain influence to the dismounting of paper.
In order to eliminate above-mentioned influence, the cross sectional shape of the rotation hole of described rotation section rotation hole and lock piece is 3/4ths circles, described rotating shaft and the cross sectional shape of the rotation section rotation hole section of cooperation be 3/4ths justify, be semicircle with the cross sectional shape of the lock piece rotation hole section of cooperation.
Setting by above-mentioned rotation hole, turning cylinder cross sectional shape, lock piece is rotated earlier drive again behind 90 degree right half-turn shape portion to rotate, even the rotational angle of opening right half-turn shape portion is less than 90 degree, lock piece can not stop at the centre of left half-turn shape portion and right half-turn shape portion yet, can not have influence on the dismounting of paper.And, have the interlock of time difference between lock piece and the right half-turn shape portion, make lock piece freely to turn an angle prior to right half-turn shape portion, when being provided with a plurality of lock piece, a plurality of lock pieces can successively be opened respectively, open synchronously and needn't impose, and make things convenient for user's practical operation.
The utility model modern design, rational in infrastructure, adopt button interlock mode, have convenient, the safe in utilization characteristics of operation.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1,2,3, the utility model button loose-leaf binder comprises the cast portion 1 that is formed by left half-turn shape portion 3 and right half-turn shape portion 4 and cast portion 1 can be installed in substrates 2 on the loose-leaf notebook strip of paper used for sealing, and left half-turn shape portion 3 is installed in substrate 2; Right side half-turn shape portion 4 belows are provided with rotation section 5, and this rotation section 5 is provided with rotation hole 6, form hinged relationship by rotating shaft 8 and substrate 2; Be with in the described rotating shaft 8 and can drive the lock piece that has buckle 10 9 that rotate rotation section 5, right half-turn shape portion 4; The position of corresponding buckle 10 is provided with the catching groove 11 adaptive with buckle 10 on the substrate 2; The cross sectional shape of the rotation hole 7 of described rotation section 5 rotation holes 6 and lock piece 9 is 3/4ths circles, described rotating shaft 8 and the cross sectional shape of rotation section 5 rotation holes, 6 sections of cooperation be 3/4ths justify, be semicircle with the cross sectional shape of lock piece 9 rotation holes 7 sections of cooperation.
