Technical Field

[0001] This utility model relates to the field of binding buckle technology, specifically to a self-locking binding buckle for folding brochures. Background Technology

[0002] A binding clip is a connector used to secure multiple sheets of paper, documents, tickets, and other materials together. Its main function is to prevent materials from scattering and to facilitate organization, storage, and browsing. A self-locking binding clip for folding brochures is an accessory used to secure the pages of folding brochures (such as tri-fold or multi-fold booklets). Its core feature is that it "locks itself without additional tools," quickly securing folded sections or multi-page structures while also facilitating disassembly and reuse.

[0003] However, the existing self-locking binding clips for folding brochures have limited applicability and are difficult to apply to binding holes of various sizes. When the binding hole is larger than the clip size, the clip may come loose. Therefore, a self-locking binding clip for folding brochures was invented. Utility Model Content

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0016] This utility model provides a self-locking binding clip for folding brochures; please refer to [link / reference]. Figures 1-4 The device includes a first circular plate 10 and a second circular plate 20 arranged opposite to each other. A first hollow tube 11 is fixedly installed on the side of the first circular plate 10 facing the second circular plate 20. A second hollow tube 21 is fixedly installed on the side of the second circular plate 20 facing the first circular plate 10, and the second hollow tube 21 is inserted into the first hollow tube 11. The inner surface of the first hollow tube 11 is provided with an internal thread 12, and the outer surface of the second hollow tube 21 is provided with an external thread 22. The internal thread 12 and the external thread 22 are threadedly connected.

[0017] It also includes: a support assembly for increasing the limiting area of ​​the first circular plate 10 and the second circular plate 20, and the first circular plate 10 and the second circular plate 20 are both provided with the support assembly; The support assembly includes: a storage slot 30, a limiting rod 31, and a drive plate 32; Both the first circular plate 10 and the second circular plate 20 have a plurality of storage slots 30 arranged in a ring. The limiting rod 31 is slidably connected in the storage slot 30. One end of the limiting rod 31 is fixedly installed with a driving plate 32 so that force can be applied to make the limiting rod 31 slide in the storage slot 30.

[0018] The support assembly further includes a fixing component for fixing the limiting rod 31 in the storage groove 30, and the fixing component is disposed on the limiting rod 31.

[0019] The fixing assembly includes: a through hole 40, a support plate 41, a sliding hole 42, a sliding rod 43, a positioning block 44, a positioning groove 45, and a damping spring 46; The other end of the limiting rod 31 is provided with several through holes 40. The support plate 41 is fixedly installed in the through holes 40. The sliding hole 42 is opened in the support plate 41. The sliding rod 43 is slidably connected in the sliding hole 42. The positioning block 44 is fixedly installed on one end of the sliding rod 43. Several positioning grooves 45 are opened on both sides of the inner surface of the receiving groove 30. The positioning block 44 is inserted into a set of positioning grooves 45. The sliding rod 43 is fitted with a damping spring 46. The two ends of the damping spring 46 are fixedly connected to the support plate 41 and the positioning block 44 respectively. The positioning block 44 and the positioning groove 45 are hemispherical in shape.

[0020] In practical use, the specific operating steps for those skilled in the art are as follows: First, punch holes in the folded brochure to be bound to obtain binding holes. Then, pass the first hollow tube 11 through the binding holes. After that, thread the second hollow tube 21 into the first hollow tube 11 to achieve self-locking. Thus, the folded brochure is positioned between the first circular plate 10 and the second circular plate 20. When the binding hole size is larger than the size of the first circular plate 10 or the second circular plate 20 (the sizes of the first circular plate 10 and the second circular plate 20 are set to be the same), the limiting rod 31 will slide in the receiving groove 30 through the driving plate 32. At this time, the positioning block 44 will be squeezed so that the positioning block 44 is located in the through hole 40. During this process, the damping spring 46 will deform until the size formed by several limiting rods 31 is larger than the size of the binding hole. Then, the positioning block 44 can be inserted into the corresponding positioning groove 45 through the damping spring 46 to fix the limiting rod 31.

[0021] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
