Description

The fixture of loose-leaf binder base and binder

The utility model relates to loose-leaf binder, refer to especially a kind of binder can with the fastening loose-leaf binder base that combines of base and the fixture of binder.

Loose-leaf binder is a kind of quite general and practical stationery, though the cost of first purchase is more expensive, and because of interior page or leaf can replenish or change loose leaf paper at any time, so that average use cost is more generally bound is cheap, and also flexible.

Substantially comprise two parts referring to Fig. 1,2, loose-leaf binder 10, one is that base 11, is a binder 12, and wherein base 11 is combined on the front cover of loose-leaf a surname 15, respectively rivets a rivet 13 at least at two ends; Binder 12 includes the hole 14 of corresponding above-mentioned rivet position, and rivet 13 passes binder 12, will not have the other end hammer circle of head to be riveted tightly with hand hammer or riveting machine again, and binder 12 is combined on the base 11, uses for the bookbinding loose leaf paper.Though it is not riveted type loose-leaf binder 10 is very firm,, very attractive in appearance because of rivet 13 heads are exposed to binder 12 upper surfaces.

In order to solve this shortcoming, released a kind of buckle-type loose-leaf binder 20.As shown in Figure 3, this loose-leaf binder 20 is made up of a base 21 and binder 22 equally, and wherein base 21 utilizes stamping technology to make unsealed curve to cut off at least at two ends, cut off part by drift outwardly side blow go out one group of back-to-back lance hook 23; 24 pilot holes 25 that are provided with corresponding lance hook 23 positions on the bottom of binder 22, these pilot hole 25 part broads, part is narrower, during installation, aim at lance hook 23 for wide with pilot hole 25, promote binder 22 more vertically and make narrow of pilot hole 25, thus binder 22 is fixed on the base 21 with lance hook 23 buckles (referring to Fig. 5).

Because of utilizing on the bottom 24 pilot hole 25 to cooperate with lance hook 23 on the base 21, binder 22 combines, its bound fraction is hidden in binder 22 basal surfaces, binder 22 upper surfaces be can not see the rivet vestige fully, so can keep the overall appearance of loose-leaf binder 20 (referring to Fig. 4, sequence number 26 is a loose-leaf notebook among the figure, 27 is front cover), solved the drawback that buckle-type loose-leaf binder 10 is destroyed by rivet 13 vestiges; In other words, buckle-type loose-leaf binder 20 is attractive in appearance than riveted type loose-leaf 10.

Yet because the binder 22 of buckle-type loose-leaf binder 20 can axially promote, in case binder 22 during towards the passing of 25 wide sides of pilot hole, lance hook 23 just can lose snap effect with pilot hole 25, and binder 22 is come off from base 21.Therefore, though buckle-type loose-leaf binder 20 solves the inaesthetic shortcoming of rivet type loose-leaf binder 10, also bring firm inadequately drawback.

The purpose of this utility model is to address the above problem and shortcoming, and the fixture of a kind of loose-leaf binder base and binder is provided, and makes loose-leaf binder have the firm and buckle-type loose-leaf binder dual characteristics attractive in appearance of riveted type loose-leaf binder simultaneously concurrently.

The purpose of this utility model is to be achieved through the following technical solutions: the fixture of a kind of loose-leaf binder base and binder, mainly comprise: loose-leaf binder base and binder are formed, wherein base is respectively riveted a rivet at least at two ends, it is characterized in that: the fixed cap of binder be provided with to should the rivet position insert hole in the binder for rivet, the lock washer corresponding with it is positioned above the hole and the crimping rivet circumference.

The utility model also can be realized by following measure: above-mentioned hole both sides are provided with unsealed curve and cut off part, and this cuts off the pressing plate that part is bent to form for the level towards the hole direction; Be provided with the sawtooth of a plurality of projections that are inclined upwardly around the circle hole of above-mentioned lock washer, the aperture that these sawtooth terminations surround is less than the diameter of rivet; Be provided with the sawtooth in order to the crimping rivet circumference of a plurality of projections that are inclined upwardly around the above-mentioned hole.

Now further specify by the following drawings and embodiment:

Fig. 1, for commonly using the stereogram of riveted type loose-leaf binder;

Fig. 2, for commonly using the schematic diagram that the riveted type loose-leaf binder is loaded on loose-leaf notebook;

Fig. 3, for commonly using the stereogram of buckle-type loose-leaf binder;

Fig. 4, for commonly using the schematic diagram that the buckle-type loose-leaf binder is loaded on loose-leaf notebook;

Fig. 5, be the profile of A-A line among Fig. 4;

Fig. 6, be three-dimensional exploded view of the present utility model.

Fig. 7, be loaded on the schematic diagram of loose-leaf notebook for the utility model;

Fig. 8, be the profile of B-B line among Fig. 7.

Referring to the fixture of Fig. 6, a kind of loose-leaf binder base and binder, wherein base 31 is respectively riveted a rivet 33 at least at two ends; Certainly along with the increase of base 31 length, should set up more than one rivet in the centre, make base 31 and the combining of binder 32 can be more firm.The bottom 34 of binder 32 is provided with the hole 35 of corresponding rivet 33 positions, inserts in the binder 32 for rivet 33; In addition, these hole 35 both sides utilize stamping technology to make unsealed curve and cut off, cut off part and gone out the pressing plate 38 that the level towards hole 35 directions is bent to form by drift, in order to compress the lock washer 36 that is installed in above the hole 25, be provided with the sawtooth 37 of a plurality of projections that are inclined upwardly around the circle hole of this lock washer 36, the aperture that these sawtooth 37 terminations surround is less than the diameter of rivet 33, when rivet 33 force pass lock washer 36 after, sawtooth 37 just can be accumulated elasticity, and by means of its elastic-restoring force crimping rivet 33 circumference, binder 32 can be incorporated on the base 31 securely, and its situation as shown in Figure 8.

Though above-mentioned lock washer 36 is to be installed in addition on the bottom 34, but because of bottom 34 is the sheet metal punch forming, thus also can directly around hole 35, stamp out required sawtooth 37, and omit lock washer 36, the embodiment of accompanying drawing is intended to illustration and explanation, and is not intended to be limited to any specific forms.

The utility model has the advantage of: because rivet 33 do not pass binder 32, and binder 32 with The bound fraction of base 31 is hidden in again between the contact-making surface of the two, so binder 32 upper surfaces do not have fully Any rivet vestige, (referring to Fig. 7, sequence number 39 among the figure so make loose-leaf binder 30 can obtain surface attractive in appearance Be loose-leaf notebook, 40 is front cover); In addition, be to borrow lock washer 36 to clamp base 31 because of binder 32 On rivet 33, so the combination of the two is very firm, even if apply level or vertical at binder 32 Strength, also absolutely not with the problem of base 31 disengagings, so thoroughly solved traditional riveted type loose-leaf binder 10 The drawback of being destroyed by the rivet vestige, and buckle-type loose-leaf binder 20 holds caducous shortcoming.
