Abstract

The utility model relates to a fixing structure of inner pages, mainly comprising outer pages, inner pages and a fixing rod which is provided with a convex column, and the convex column is penetrated in the outer pages and the inner pages and then is fixedly arranged on the fixing rod. The appropriate position of the fixing rod is provided with a sealing through hole, one side of the through hole is provided with an elongated slot, and the convex column of the fixing rod is penetrated in a main through hole to clamp on the elongated slot. The utility model not only can cause the fixing rod to be clamped without disengagement really, simultaneously, the tightness action can be adjusted moderately, causing more tightness efficiency to be arranged between the inner pages and the outer pages.

Description

The fixed structure of interior page or leaf

The utility model relate to a kind of in the fixed structure of page or leaf, it not only can make fixed bar have more certain snap action and not have the phenomenon of any disengagement, simultaneously, also have appropriateness adjust in degree of tightness effect between page or leaf and outer page.

The fixed structure of page or leaf in commonly using, see also Figure 1 and Figure 2, the page or leaf 1 middle hole (indicating among the figure) that is provided with reaches the interior page or leaf 2 middle holes (indicating among the figure) that are provided with outside wherein being somebody's turn to do, for the projection 31 of fixed bar 3 can through the hole (indicating among the figure) of outer page or leaf 1 and in the hole (indicating among the figure) of page or leaf 2 after, be inserted in again in the hole 32 of the fixed bar 3 that both sides bend inwards, and a side of this hole 32 is provided with a breach 321, in order to projection 31 thus breach 321 slip in this hole 32; Yet it still has following puzzlement in the use:

1, because fixed bar 3 is the plastic cement lamellar body of a very thin thickness, therefore, when projection 31 is desired to clamp-on breach 321, this breach 321 is enlarged because of the stressed effect of rerum natura and extruding, and then this projection can be slided in breach because of stressed, and cause the phenomenon that also breaks away from.

2, be fastened on interior page or leaf owing to the both sides of fixed bar are distolateral and reach outer page the outside, therefore, it also is easier to be touched, and causes an end of fixed bar to separate with projection in use.

3, owing to the storing CD of page or leaf system sheet in being somebody's turn to do, therefore, meeting easily make the projection of fixed bar stressed because of the weight of CD sheet, and then makes the hole of this projection and fixed bar produce the phenomenon of separating disengaging.

Main purpose of the present utility model tie up to provide a kind of in the fixed structure of page or leaf, it not only can make outside the engaging of fixed bar can separate more really and not to some extent, simultaneously, in also adjusting page or leaf and outside page between elasticity.

For reaching above-mentioned purpose, page or leaf, interior page or leaf and fixed bar were formed outside the utility model comprised, wherein fixed bar is provided with projection, after can penetrating outer page or leaf and interior page or leaf, be fixedly arranged on the fixed bar again, the appropriate location of fixed bar is provided with the through hole of sealing, and being provided with elongated slot in a side of through hole, the projection of fixed bar penetrates in the through hole and is sticked on the elongated slot.

Can be provided with portion of class in the utility model through hole.Also can be provided with portion of class in the elongated slot.Also can be provided with some radians on the elongated slot.And the end of projection can be provided with protuberance, and is provided with profile groove in protuberance.

After adopting said structure, the utility model utilizes the projection of fixed bar can be inserted in effectively in the sealing through hole of fixed bar of the back that bends inwards, and then the protuberance that makes projection can be sticked in the portion of class, so, it not only can increase outside the tightness of its fastening really, simultaneously, also can not be subjected to the power of colliding a little, and the phenomenon that the projection that makes fixed bar and through hole separate, and then can not make be placed in the article of page or leaf drop and damage.Again because the side of through hole is connected with elongated slot, and be provided with radian, so, can control the position of projection effectively in elongated slot, and then page or leaf number and the elasticity when page cooperating outward in control.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 2 is the partial cutaway schematic of the fixed structure of page or leaf within commonly using;

Fig. 3 is the three-dimensional appearance schematic diagram of the fixed bar of the fixed structure of page or leaf within the utility model;

Fig. 4 is the partial cutaway schematic of the fixed structure of page or leaf within the utility model;

Fig. 5 is the solid combination schematic appearance of the fixed structure of page or leaf within the utility model;

Fig. 6 is the sectional perspective enlarged diagram of another embodiment of the fixed structure of page or leaf within the utility model.

See also shown in Fig. 3-5, it mainly ties up to the through hole 43 that is provided with sealing in the two side ends of fixed bar 4, the through hole 43 inner portions of class 431 that form, one of through hole 43 side is connected with an elongated slot 44, and be provided with portion of class 441 in elongated slot 44 inside, and elongated slot 44 and portion of class 441 thereof can be interconnected with through hole 43 and portion of class 431 thereof; In addition, appropriate location, one of fixed bar 4 side is provided with projection 41 and recess 42, and be provided with protuberance 411 in the end of projection 41, and in the middle of protuberance 411, be provided with profile groove 411a, when bending inwards, slip into again in this elongated slot 44 after making projection 41 be sticked in the sealing through hole 43 of two side ends for the two side ends of fixed bar 4.

Therefore, when the projection 41 of desiring to make fixed bar 4 can be sticked in the through hole 43 of sealing, then need earlier with the projection 41 of fixed bar 4 respectively through outer page or leaf 1 and in behind the relative position of page or leaf 2, two side ends with fixed bar 4 is that the axle center bends inwards with recess 42 again, at this moment, because the slightly larger in diameter of the protuberance 411 of this projection 41 is in the diameter of the portion of class 431 of through hole 43, and also be provided with profile groove 411a in the middle of the protuberance 411, add fixed bar 4 and be the made article of plastic cement material, therefore, when the protuberance 411 of projection 41 is desired to penetrate in the portion of class 431 of through hole 43, only need the both sides of protuberance 411 are pushed downwards, or after the suitable strength of directly pressurizeing, can make protuberance 411 because of after being subjected to drag effect and making both sides downward-sloping, penetrate in the portion of class 431 of through hole 43, also can make the both sides of protuberance 411 reply the origin-location after waiting to be subjected to resistance to disappear, and then can be sticked in the portion of class 431, projection 41 is slipped in this elongated slot 44, and protuberance 411 is sticked in the portion of class 441.

See also shown in Figure 6 again, it is another preferred embodiment for the utility model, its main change ties up to and form a portion of class 431 in the through hole 43 of sealing, and be connected with an elongated slot 44 in the side of through hole 43, and be provided with a portion of class 441 in the elongated slot 44, wherein elongated slot 44 is provided with several suitable radians 442, when moving in the elongated slot 44 for the protuberance 441 of projection 41, just can make radian 442 can engage the protuberance 411 of projection 41, and can not make projection 41 mobile to some extent, and then reach the effect of its location.
