Description

Technical Field

[0001] The utility model belongs to the field of loose-leaf folders, in particular to a novel loose-leaf folder for binding loose-leaf papers. Background Art

[0002] A binder, also known as a loose-leaf notebook or loose-leaf notepad, is a tool used to store and organize loose-leaf paper. It usually consists of a cover, binder rings (also called binder strips, binder buckles), and inner pages (loose-leaf paper). The design of a binder allows users to add, remove, or replace inner pages at any time as needed, providing great flexibility and convenience.

[0003] The existing Chinese patent CN212353345U discloses a portable iron-bottomed binder for storing loose-leaf paper, including a first clamp, a second clamp and a metal base, wherein the first clamp, the second clamp and the metal base are all in the shape of long strips; a groove with an arc-shaped cross section is provided on the metal base, and a plurality of first arc hooks bent inward are provided on the outer edge of the first clamp; a plurality of second arc hooks bent inward are provided on the outer edge of the second clamp; the number of the second arc hooks is the same as the number of the first arc hooks and corresponds to each other; the inner edge of the first clamp is hinged with the inner edge of the second clamp to form a binder body, the bottom of the binder body is in the groove, and the outer edge of the first clamp and the outer edge of the second clamp are respectively tightly embedded in the two side edges of the metal base; the corresponding first arc hooks and the second arc hooks are clamped and matched. This iron-bottomed binder has a simple structure, is easy to operate, is sturdy and reliable, can freely load and unload loose-leaf paper, can be carried around, can be used repeatedly, and is environmentally friendly and practical.

[0004] like Fig. 9 As shown, the above-mentioned binder uses an extended support plate to support the pivotal structure of the inner edge of the first clamp and the inner edge of the second clamp. In order to reserve a movable space for the support plate, the binder uses a metal base with an arc-shaped groove. When the binder is in use, the metal base will raise the height of the loose-leaf paper, making it difficult to keep the loose-leaf paper flat. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a novel loose-leaf paper binder to solve the problem in the prior art that when the loose-leaf paper binder is in use, the metal base will raise the height of the loose-leaf paper, making it difficult to keep the loose-leaf paper flat.

[0014] Preferably, a second limiting block is fixedly connected to the first clamp body;

[0015] The second clamping strip body is provided with a second movable groove;

[0016] When the first clamp bar body and the second clamp bar body are combined and embedded on the support bar through the limiting strip, the limiting block 2 can move in a limited position in the movable groove 2, thereby limiting the separation of the first clamp bar body and the second clamp bar body.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] like Figures 1 to 3 As shown:

[0047] Embodiment 1: The utility model provides a novel loose-leaf binder for binding loose-leaf paper, comprising:

[0048] The clamping mechanism 1 comprises a first clamping bar assembly 11 and a second clamping bar assembly 12 matching the first clamping bar assembly 11. The lower edge positions of the first clamping bar assembly 11 and the second clamping bar assembly 12 are respectively provided with clamping edges.

[0049] The bottom support mechanism 2 includes a support bar 21, and position-limiting strips 22 disposed on both sides of the upper side of the support bar 21. The first clamping bar assembly 11 and the second clamping bar assembly 12 are symmetrically position-limited and clamped on the support bar 21 through the position-limiting strips 22;

[0050] The bottom of the support bar 21 is flush, the clamping mechanism 1 and the bottom support mechanism 2 are both made of plastic, and the part where the support bar 21 and the limiting strip 22 are connected can be slightly deformed;

[0051] The first clamp bar assembly 11 and the second clamp bar assembly 12 can be combined into a closed state, and the first clamp bar assembly 11 and the second clamp bar assembly 12 can be combined into an open state. The first clamp bar assembly 11 and the second clamp bar assembly 12 can switch between the closed state and the open state. When the first clamp bar assembly 11 and the second clamp bar assembly 12 are in the closed state, the limiting strip 22 can play a limiting role;

[0052] Among them, the bottom support mechanism 2 is placed stably on the desktop through the support bar 21, the first clamping bar assembly 11 and the second clamping bar assembly 12 are controlled to be in an open state, the side with the hole on the loose-leaf paper is clamped on the second clamping bar assembly 12, and the first clamping bar assembly 11 and the second clamping bar assembly 12 are controlled to be in a closed state. At this time, the loose-leaf paper can be limited. When the loose-leaf paper is used, the support bar 21 arranged flush with the bottom can ensure that the loose-leaf paper is placed flat on the desktop.

[0053] like Figures 4 to 6 As shown:

[0054] Specifically, the first clamping bar assembly 11 includes a first clamping bar body 111, and a movable groove 112 is formed on the first clamping bar body 111;

[0055] The second clamping bar assembly 12 includes a second clamping bar body 121, and a limiting block 122 is fixedly connected to the second clamping bar body 121;

[0056] When the first clamping bar body 111 and the second clamping bar body 121 are combined and embedded on the support bar 21 through the limiting strip 22, the limiting block 122 can be limited and movable in the movable groove 112, thereby limiting the separation of the first clamping bar body 111 and the second clamping bar body 121;

[0057] The first clamping bar body 111 and the second clamping bar body 121 can be restricted from separating by the limiting block 122 moving in the movable groove 112 .

[0058] Specifically, the first clamp body 111 is fixedly connected to the second limiting block 113;

[0059] The second clamping strip body 121 is provided with a second movable groove 123;

[0060] When the first clamping bar body 111 and the second clamping bar body 121 are combined and embedded on the support bar 21 through the limiting strip 22, the second limiting block 113 can be limited and movable in the second movable groove 123, thereby limiting the separation of the first clamping bar body 111 and the second clamping bar body 121;

[0061] The second limiting block 113 is limited and movable in the second movable groove 123 , so as to limit the separation of the first clamping bar body 111 and the second clamping bar body 121 .

[0062] Specifically, the first clamp body 111 is also fixedly connected with a half ring 114;

[0063] The second clamp body 121 is also fixedly connected to a second half ring 124;

[0064] The first half ring 114 can be closed with the second half ring 124;

[0065] The first half ring 114 is also provided with a convex ball, and the second half ring 124 is provided with a ball groove matching the convex ball. When the first half ring 114 and the second half ring 124 are closed together, the convex ball can be embedded in the ball groove.

[0066] When the first half ring 114 and the second half ring 124 are closed together, the convex ball is embedded in the ball groove, thereby limiting the position of the loose-leaf paper.

[0067] Specifically, a half hole 115 is also formed on the first clamp body 111;

[0068] The second clamp body 121 is also provided with a second half hole 125;

[0069] The first half hole 115 can be combined with the second half hole 125 to form a round through hole;

[0070] The support bar 21 is also provided with a binding hole 23;

[0071] The positions of the binding holes 23 and the round through holes correspond to each other;

[0072] Among them, the binding hole 23 and the round through hole are penetrated by using rivets, so that the binder can be bound with plastic cover, leather, etc.

[0073] As can be seen from the above, a double limiting mechanism is formed by the limiting movement of the limiting block 122 in the movable groove 112 and the limiting movement of the limiting block 113 in the movable groove 123, thereby enhancing the connection stability between the first clamping bar body 111 and the second clamping bar body 121, effectively preventing them from being accidentally separated during use, and improving the stability and reliability of the binder;

[0074] The design of the first half ring 114 and the second half ring 124 allows the user to fix the loose-leaf paper in the binder by a simple closing action, while the matching of the convex ball and the ball groove ensures the stability of the fixation.

[0075] like Figure 7 and Figure 8 As shown:

[0076] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that both ends of the first clamp body 111 are fixedly connected with an open half clamp 116;

[0077] The two ends of the second clamp body 121 are also fixedly connected with the second open half clamp 126;

[0078] After pressing the half clamp 1 116 and the half clamp 2 126 relatively, the first clamp body 111 and the second clamp body 121 can be rotated on the bottom support mechanism 2, and the half ring 1 114 and the half ring 2 124 can be separated from each other.

[0079] Pressing the half ring 114 and the half ring 2 124 relative to each other can make the first clamp body 111 and the second clamp body 121 rotate in opposite directions on the bottom support mechanism 2, and at the same time make the half ring 114 and the half ring 2 124 close to each other;

[0080] Among them, by relatively pressing to open half clamp one 116 and half clamp two 126, the first clamp body 111 and the second clamp body 121 can be rotated on the bottom support mechanism 2, and the half ring one 114 and the half ring two 124 can be separated from each other; by relatively pressing half ring one 114 and half ring two 124, the first clamp body 111 and the second clamp body 121 can be rotated in the opposite direction on the bottom support mechanism 2, and the half ring one 114 and the half ring two 124 can be closed together.

[0081] Specifically, one side of the opened half clamp 116 is also fixedly connected to a limited edge 117;

[0082] One side of the opened half clamp 126 is also fixedly connected to the limited edge 127;

[0083] The first limiting edge 117 can limit the range of movement of the second half clamp 126, and the second limiting edge 127 can limit the range of movement of the first half clamp 116;

[0084] When the first clamping strip assembly 11 and the second clamping strip assembly 12 are in the open state, the first limiting edge 117 and the second limiting edge 127 can play a limiting role;

[0085] Among them, the activity range of the opened half clamp 126 can be limited by the limiting edge 117, and the activity range of the opened half clamp 116 can be limited by the limiting edge 127.

[0086] As can be seen from the above, by opening half clamp 116 and opening half clamp 2 126, the user can easily open the clamping mechanism by pressing these two components relative to each other, and the limiting function of the clamping mechanism is further enhanced by the design of limiting edge 117 and limiting edge 2 127.
