Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1-9 As shown, this is a two-handed binder according to an embodiment of the present invention, including a main body 1, a first clamp 2, and a second clamp 3. The first clamp 2 and the second clamp 3 are respectively disposed at both ends of the main body 1. The first clamp 2 and the second clamp 3 have a sliding structure with the main body 1, so that they can slide independently relative to the main body 1 laterally, thereby controlling the opening and closing of the binder. Correspondingly, the two ends of the main body 1 are also provided with a first pull member 4 and a second pull member 5. The first pull member 4 and the second pull member 5 can slide independently relative to the main body 1 vertically. The vertical sliding of the first pull member 4 can drive the first clamp 2 to slide laterally, and the vertical sliding of the second pull member 5 can drive the second clamp 3 to slide laterally. Furthermore, the two ends of the main body 1 are provided with fixed half-rings 6. The first clamp 2 is provided with a first half-ring that can engage with the half-ring 6 at one end of the main body 1, and the second clamp 3 is provided with a second half-ring that can engage with the half-ring 6 at the other end of the main body 1.

[0031] like Figures 2-7As shown, the sliding structure includes a first strip groove 11 and a second strip groove 12 disposed at both ends of the main body 1, a first slider 21 disposed at both ends of the first clamp 2, and a second slider 31 disposed at both ends of the second clamp 3. The first clamp 2 can slide laterally within the first strip groove 11, and the second clamp 3 can slide laterally within the second strip groove 12. Correspondingly, the first strip groove 11 has a first transverse sliding groove 111 at both ends, and the second strip groove 12 has a second transverse sliding groove 121 at both ends. The first slider 21 can slide laterally within the first strip groove 11. The second slider 31 slides within the second transverse slide groove 121. Through the cooperation of the first slot 11 with the first clamp 2, and the cooperation of the second slot 12 with the second clamp 3, the first clamp 2 and the main body 1, as well as the second clamp 3 and the main body 1, can achieve sliding opening and closing movements. The first slot 11 contains a first guide slide 112, and the bottom centerline of the first guide slide 112 has a first support strip 113 extending along its length. The second slot 12 contains... The first clamp 2 has a second guide slide 122, and a second support bar 123 extending along its length is provided on the center line of the bottom surface of the second guide slide 122. Correspondingly, the first clamp 2 has a first slot 22 that matches the number and position of the first guide slide 112. One end of the first slot 22 has a first opening, and the first guide slide 112 can be inserted into the first slot 22 through the first opening to slide. The bottom surface of the first slot 22 has a first limiting opening 221 extending along its length, and the first support bar 113 can be inserted into the first limiting opening 221. The second clamp 3 has a second slot 32 that matches the number and position of the second guide slide 122. One end of the second slot 32 has a second opening, and the second guide slide 122 can be inserted into the second slot 32 through the second opening to slide. The bottom surface of the second slot 32 has a second limiting opening 321 extending along its length, and the second support bar 123 can be inserted into the second limiting opening 321, thereby playing a limiting role and making the sliding cooperation between the slot and the guide slide smoother.

[0032] like Figure 3 , Figure 7 and Figure 8As shown, the first clamp 2 has an upper inclined groove 23, the second clamp 3 has a lower inclined groove 33, the first strip groove 11 has a first guide straight groove 13 that intersects with the upper inclined groove 23, the second strip groove 12 has a second guide straight groove 14 that intersects with the lower inclined groove 33, the first pull-out member 4 and the second pull-out member 5 are respectively provided with guide posts 7. The guide post 7 on the first pull-out member 4 passes through the first guide straight groove 13 and is placed in the upper inclined groove 23, and the guide post 7 on the second pull-out member 5 passes through the second guide straight groove 14 and is placed in the lower inclined groove 33. By sliding the guide post 7 in the first guide straight groove 13 and the upper inclined groove 23, and by sliding the guide post 7 in the second guide straight groove 14 and the lower inclined groove 33, the binder can be opened or closed; wherein, the guide post 7 has a first guide straight groove 13 that intersects with the upper inclined groove 23, the second guide straight groove 14 and the lower inclined groove 33, the binder can be opened or closed; wherein, the guide post 7 has a first guide straight groove 13 that intersects with the upper inclined groove 23, the second guide straight groove 14 and the lower inclined groove 33, the binder can be opened or closed; The buckle 71 that engages with the groove 13 and the second guide straight groove 14 has a diameter greater than the width of the first guide straight groove 13 and the second guide straight groove 14. In addition, the lower end of the upper inclined groove 23 is provided with an upper longitudinal groove 24, the upper end of which is connected to the lower end of the upper inclined groove 23. The upper end of the lower inclined groove 33 is provided with a lower longitudinal groove 34, the lower end of which is connected to the upper end of the lower inclined groove 33. When the binder is engaged, the guide post 7 of the first pull member 4 is in the upper longitudinal groove 24, and the guide post 7 of the second pull member 5 is in the lower longitudinal groove 34. The guide post 7, the upper longitudinal groove 24, and the lower longitudinal groove 34 will form mutual constraints, making it impossible to directly open the engaged half-buckle ring 6. It can only be opened by pulling out the first pull member 4 and the second pull member 5.

[0033] like Figure 8 and 9As shown, the structure of the first pull-out component 4 is the same as that of the second pull-out component 5, and they are symmetrically distributed. Therefore, this embodiment will focus on the first pull-out component 4. The first pull-out component 4 includes a long slide bar 41 and a short slide bar 42. One end of the long slide bar 41 and the short slide bar 42 are integrally connected, and a U-shaped opening 43 is formed between them. The back of the main body 1 is also provided with a straight slide groove 15 extending along its length direction and a shorter receiving slot 16 adjacent to the straight slide groove 15. The long slide bar 41 slides in the straight slide groove 15, and the short slide bar 42 slides in the receiving slot 16. The 5 and the receiving slot 16 are also symmetrically distributed on the main body 1 for sliding the second pull-out component 5; wherein, a limiting groove 44 is provided on the edge of the short slide bar 42, and a first slot 45 is provided at the upper end of the limiting groove 44. A ramp protrusion 46 is provided between the limiting groove 44 and the first slot 45. Correspondingly, an arc-shaped locking point 161 is provided on the groove wall corresponding to the receiving slot 16 and the first slot 45. When the binder is in the closed state, the arc-shaped locking point 161 is placed in the first slot 45. The arc-shaped locking point 161 can be inserted into the limiting groove 44 along the ramp protrusion 46 and can also be disengaged along the ramp protrusion 46. The arc-shaped locking point 161, positioned away from the limiting groove 44, engages with the first locking groove 45 along the sloping protrusion 46, thereby locking the first pull-out component 4 and preventing it from moving easily. This state is the snap-fit ​​state of the binder. A second locking groove 47 is provided at the lower end of the limiting groove 44, and an adjustment groove 421 is provided on the short slide bar 42. The position of the adjustment groove 421 corresponds to the limiting groove 44, the first locking groove 45, and the second locking groove 47. An arc-shaped protrusion 48 is provided between the second locking groove 47 and the limiting groove 44. When the arc-shaped locking point 161 moves within the limiting groove 44, it can engage with the second locking groove 47 along the arc-shaped protrusion 48. It can also disengage from the second slot 47 along the arc protrusion 48, and the arc locking point 161 can be inserted into the second slot 47 along the arc protrusion 48, thereby locking the first pull piece 4 again, so that the first clip 2 and the main body 1 will not slide randomly during the binding process, and the binding operation is more stable. This state is the open state of the binder; in addition, a handle 49 is provided at the connection between the long slide bar 41 and the short slide bar 42. The handle 49 can drive the first pull piece 4 to slide vertically. The width of the handle 49 is smaller than the width of the main body 1, so it is not easy for the user to get stuck when turning the pages.

[0034] In summary, the specific working process of the two-handed binder embodiment provided by the present invention is as follows:

[0035] A. When the binder is in the locked state, the guide post 7 of the first pull-out piece 4 is in the upper longitudinal slot 24, the guide post 7 of the second pull-out piece 5 is in the lower longitudinal slot 34, the arc-shaped locking point 161 is placed in the first slot 45 of the first pull-out piece 4, and the second pull-out piece 5 is symmetrical to the first pull-out piece 4.

[0036] B. When the binder needs to be opened, the user holds the handles 49 of the first pull-out piece 4 and the handles of the second pull-out piece 5 with both hands and pulls the first pull-out piece 4 and the second pull-out piece 5 outwards. The long slide bar 41 and the short slide bar 42 of the first pull-out piece 4 slide along the straight slide groove 15 and the receiving slot 16 respectively. The arc-shaped locking point 161 is engaged in the limiting groove 44 along the ramp protrusion 46. Continuing to slide, the arc-shaped locking point 161 is engaged in the second locking slot 47 along the arc-shaped protrusion 48. The second pull-out piece 5 also slides in the same way. This causes the guide post 7 of the first pull-out piece 4 to slide within the first guide straight groove 13 and the upper inclined groove 23, and the guide post 7 of the second pull-out piece 5 to slide within the second guide straight groove 14 and the lower inclined groove 33. Since the guide posts 7 of the first pull-out piece 4 and the second pull-out piece 5 are constrained by the first guide straight groove 13 and the second guide straight groove 14 respectively, they can only slide vertically. Therefore, the second clamp 2 with the upper inclined groove 23 and the third clamp 3 with the lower inclined groove 33 can only slide horizontally, thereby putting the binder in the open state.

[0037] C. When the binder needs to be fastened, the user holds the handles 49 of the first pull-out piece 4 and the handles of the second pull-out piece 5 with both hands, and pushes the first pull-out piece 4 and the second pull-out piece 5 inward. The long slide bar 41 and the short slide bar 42 of the first pull-out piece 4 slide along the straight slide groove 15 and the receiving slot 16 respectively. The arc-shaped locking point 161 is engaged in the limiting groove 44 along the arc-shaped protrusion 48. Continuing to slide, the arc-shaped locking point 161 is engaged in the first locking groove 45 along the slope protrusion 46. The second pull-out piece 5 also slides in the same way, so that the guide post 7 of the first pull-out piece 4 is in the first guide straight groove 1. The guide post 7 of the second pull member 5 slides within the upper inclined groove 23 and the lower inclined groove 33. Since the guide posts 7 of the first pull member 4 and the second pull member 5 are constrained by the first guide groove 13 and the second guide groove 14 respectively, they can only slide vertically. Therefore, the second clamp 2 with the upper inclined groove 23 and the third clamp 3 with the lower inclined groove 33 can only slide horizontally, so that the binder is in the snap-fit ​​state. The guide post 7 of the first pull member 4 is in the upper longitudinal slot 24, and the guide post 7 of the second pull member 5 is in the lower longitudinal slot 34.
