As shown in figure 1, the elastic clamp body 2 in the clamped photo album is opened by turning over the front cover forming plate 1 and the back cover forming plate 6 simultaneously and taking A and B as fulcrums respectively, so as to pry the elastic clamp body to open, the function of the strong connecting cloth 3 is particularly important, the elastic clamp body must be firmly connected with the elastic clamp body 2 (and fixed by a fastening bolt 5), and meanwhile, the elastic clamp body needs to be strongly bonded with the front cover forming plate 1 and the back cover forming plate 6, and at the moment, the rigidity of the front cover forming plate 1 and the back cover forming plate 6 also determines whether the operation is possible or not.

The elastic clamp body 40 is a rigid integrally-formed triangular elastic metal body, strong connecting cloth is fixed on the inner surface of the elastic metal body after the elastic clamp body is formed, fastening bolts need to be driven, the process is complex, and a large amount of cost needs to be consumed; and the connection of the strong connecting cloth, the front cover piece and the back cover piece needs to be bonded by strong glue, the connection reliability determines the product function, the material cost is high, and the quality cannot be ensured.

Compared with the prior art, the loose-leaf clamping device has the advantages that the outer surface of the elastic clamp body 40 only needs to be fixed on the inner surface of the ridge sealing body 30, the stress requirement does not exist, the product function cannot be influenced, and the operation is more convenient. Meanwhile, the scheme replaces a pulling piece as a folding stress piece by the combination of the first folding support piece 51 and the first lug part 44 and the combination of the second folding support piece 52 and the second lug part 45, the folding stress piece is easier to mount, and the structure is more stable.

Referring to fig. 8, the first folding supporting element 51 and the second folding supporting element 52 are both hollow tubular cylinders, and a notch 502 is formed on a sidewall of the cylinder, and a hollow cavity of the cylinder forms an accommodating groove 501 for accommodating an ear portion, wherein a through hole is formed at an end of the cylinder contacting the notch 502.

First lug 44 projects from first clip 42 and extends in the direction of first slot 11, and second lug 45 projects from second clip 43 and extends in the direction of second slot 21. Specifically, each of the first and

second ear portions

44 and 45 includes a protruding end 401 and a fixed end 402, the protruding end 401 is inserted into the notch 502 through the through hole, and the fixed end 402 is fixed in the receiving groove 501. The thickness of the protruding end 401 is narrower than the width of the notch 502, and the thickness of the fixed end 402 is wider than the width of the notch 502, so as to ensure that the fixed end 402 is stably clamped in the receiving groove 501 after the protruding end 401 is inserted. The notch 502 is a sealed notch 502 with an opening on one side and three sides, so that the protruding end 401 is prevented from being inserted from one end of the notch 502 and extending out from the other end, and the stability of the fixed end 402 is further ensured.

In an embodiment, two ends of the elastic clamp body 40 extend out of the straight plate in the direction of the first slit 11 and the second slit 21, and then the end of the straight plate is folded to form a fixed end 402 thicker than the straight plate, wherein the thickness of the fixed end 402 is thicker than the width of the notch 502, and can play a role in limiting the extending end 401. The operation process is convenient and the cost is low. Of course, the present invention is not limited to the above-mentioned shape of the fixed end 402, and the end of the straight plate may be wound into a tubular shape to ensure that the thickness of the fixed end is thicker than the width of the notch, and any structure that can realize the thickness of the fixed end is thicker than the width of the notch is a simple modification and change of the present invention, and should fall into the protection scope of the present invention.

Further, the first folding supporting member 51 is fixed on the outer surface of the folding line of the back cover 10 and the back cover 30, and the second folding supporting member 52 is fixed on the outer surface of the folding line of the back cover 20 and the back cover 30, and the outer diameter of the folding supporting member is larger than the width of the first slit 11 and the width of the second slit 21. The widths of the first slit 11 and the second slit 21 only allow the first ear 44 and the second ear 45 to pass out, and do not allow the folding supports to be inserted, so that the connection stability between the first ear 44 and the first folding support 51 and the connection stability between the second ear 45 and the second folding support 52 are further ensured.

Referring to fig. 10-13, in an embodiment of the present invention, the leaflet clipping device further includes a first prying assembly 61 and a second prying assembly 62 adapted to the folding support member, wherein one end of the first prying assembly 61 is fixed on the first folding support member 51, and the other end of the first prying assembly 61 extends out of the sealing body 30 in a direction away from the sealing body 10; one end of the second levering assembly 62 is fixed to the second folding supporting member 52, and the other end of the second levering assembly 62 extends out of the ridge sealing body 30 in a direction away from the bottom sealing body 20.

Specifically, each of the first prying assembly 61 and the second prying assembly 62 includes a pressing portion 601 for applying a pressing force and a fixing portion 602 for connecting the fold-over support. In the specific implementation process, the prying component is formed by a steel wire framework with certain hardness, on one hand, enough hardness can be guaranteed, and on the other hand, the cost can be saved. Both ends of the first turnover supporting piece 51 and the second turnover supporting piece 52 are provided with through holes, which can facilitate the inner buckling insertion of the fixing part 602 on the steel wire framework; alternatively, a fixing portion 602 for inserting the wire frame is provided between the first folding support 51 and the second folding support 52 to be extended.

When the first prying assembly 61 and the second prying assembly 62 are adopted to assist in prying the folding support, the middle position of the first prying assembly 61 is in contact with the first turning position where the spine sealing part 31 intersects with the front cover extension part 32, and the middle position of the second prying assembly 62 is in contact with the second turning position where the spine sealing part 31 intersects with the back cover extension part 33. At this time, the first turning position becomes an action fulcrum of the first prying assembly 61, so that the first turning support 51 can be driven to pull up the first ear 44 more laborsavingly, and the second turning position becomes an action fulcrum of the second prying assembly 62, so that the second turning support 52 can be driven to pull up the second ear 45 more laborsavingly.

Before the first prying assembly 61 and the second prying assembly 62 are not used, because the lengths of the cover body 10 and the back cover body 20 are relatively long, and the included angle between the cover body 10 and the back cover body 20 in the turnover process is very small, the angles at which the clamping angles of the first clamping portion 42 and the second clamping portion 43 of the elastic clamp body 40 can be unfolded by the turnover process of the cover body 10 and the back cover body 20 are limited, that is, the number of the loose leaves such as photos that the elastic clamp body 40 can accommodate is also limited.

In this embodiment, the first prying assembly 61 and the second prying assembly 62 are adopted to assist in folding, and since the first prying assembly 61 and the second prying assembly 62 are not very long, the first prying assembly and the second prying assembly 62 can rotate within a very wide angle range, that is, the first clamping portion 42 and the second clamping portion 43 of the elastic clamp body 40 can be driven to extend from the clamping angle to the obtuse angle, so that more loose leaves such as photos can be accommodated as far as possible.

Before the first prying assembly 61 and the second prying assembly 62 are not used, since the cover body 10 and the bottom cover body 20 are required to be used as the main force application structure, the material of the cover body 10 and the material of the bottom cover body 20 need to ensure sufficient hardness, specifically, one of a hard cardboard, a hard plastic board or a hard metal board.

In the present embodiment, the first prying assembly 61 and the second prying assembly 62 are adopted to assist in folding, and the actual force application structures include the first prying assembly 61, the second prying assembly 62 and the elastic clamp 40, so that the materials of the cover body 10 and the bottom cover body 20 may not be limited, as long as normal use can be ensured, and the manufacturing cost can also be reduced to a certain extent.

In summary, under the condition that the rigidity or hardness of the cover body and the bottom body is insufficient, the elastic clamp body cannot be opened by the cooperation of the first support body and the second support body alone; meanwhile, under the condition that the shape and position sizes of the sealing body and the sealing body are too long, the elastic clamp body can not be opened by turning the sealing body and the sealing body. The first prying assembly and the second prying assembly are not limited by the conditions, the technical problem that the elastic clamp body cannot be opened effectively when the conditions happen can be avoided better, and the elastic clamp body can be opened by matching various sealing bodies and sealing bottom bodies more perfectly.

In the above embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.

In view of the above description of the technical solutions provided by the present invention, those skilled in the art will recognize that there may be variations in the technical solutions and the application ranges according to the concepts of the embodiments of the present invention, and in summary, the content of the present specification should not be construed as limiting the present invention.
