Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a pivot structure for accommodating multiple rows of tension springs and its office equipment. Background Technology

[0002] Currently, the hinge structure is one of the core opening and closing structures of copiers, scanners and other devices with opening and closing mechanisms. Copiers, scanners and other devices with covers usually use the hinge structure to open and close the covers.

[0003] Copiers and scanners typically have a platen under the cover for placing the original document to be copied or scanned. To use them, the cover is opened, the document is placed on the platen, and then the cover is closed to perform the copying or scanning. During the opening and closing process, the cover acts as a rotating component, and its opening and closing relative to the platen is achieved through a hinge structure. However, existing hinge structures have relatively small spring forces for temporary stopping, which are insufficient for effectively stopping the cover and other opening and closing components. Utility Model Content

[0045] The present invention will be further explained below with reference to specific embodiments.

[0046] like Figure 1-7As shown, this embodiment provides a pivot structure including: a fixed seat 10, a rotating seat 20, a sliding seat 30, and a spring 40; the rotating seat 20 is rotatably mounted on the fixed seat 10 via a pivot shaft 21; the sliding seat 30 is slidably mounted on the fixed seat 10 in directions away from and towards the pivot shaft 21; the two ends of the spring 40 are respectively connected to the sliding seat 30 and the fixed seat 10, tending to force the sliding seat 30 to move towards the pivot shaft 21; a cam structure 50 is provided between the rotating seat 20 and the sliding seat 30, and during the swinging process of the rotating seat 20, the sliding seat 30 is forced to reciprocate relative to the fixed seat 10 through the mutual cooperation of the cam structure 50 and the spring 40; this application includes several rows or columns of the springs 40, each column or row constituting a spring group; each spring group includes several springs 40 arranged side by side.

[0047] This application provides several sets of springs 40, with each set containing several springs 40. By providing multiple sets of springs, the force of the springs 40 is effectively increased, thereby better realizing the temporary limiting function of opening and closing components such as the cover plate.

[0048] In practical applications, it is preferable to include 2-3 spring groups. Each spring group includes 2-5 springs 40.

[0049] like Figure 3-4 As shown, in this embodiment, the pivoting mechanism includes two spring groups; the two spring groups are arranged in two parallel rows, and each row or each spring group includes 2-3 springs 40.

[0050] The slide block 30 and the fixed base 10 are provided with a connecting structure for connecting with the spring 40. The connecting structure may be a connecting post 31, a connecting strip 13, a hook, a connecting groove, a connecting hole, or a hanging lug, etc.

[0051] See Figure 3-4 and Figure 7 As shown, a connecting post 31 is provided on the slide 30; one end of all the springs 40 in the same spring group is fitted onto the same connecting post 31. Preferably, the connecting post 31 is arranged parallel or perpendicular to the pivot shaft 21. When the springs 40 in the spring group are arranged in rows (along the horizontal direction) at intervals, the connecting post 31 is arranged parallel to the pivot shaft 21; if the springs 40 in the spring group are arranged in columns (along the vertical direction) at intervals, the connecting post 31 is arranged perpendicular to the pivot shaft 21.

[0052] See Figure 6As shown, the fixed base 10 has a U-shaped cross-section, thus forming a slide structure inside, which limits the direction of sliding of the slide 30. Preferably, the fixed base 10 has a bent portion 11 at one end near the pivot shaft 21. The bent portion 11 is integrally formed with the main body of the fixed base 10, that is, the fixed base 10 is formed by bending a single plate. The bent portion 11 is formed by bending from top to bottom at one end of the slide bottom plate. Several strip-shaped openings 12 are spaced apart on the bent portion 11, thus forming multiple connecting strips 13. One end of the spring 40 in the upper spring assembly is hooked onto different connecting strips 13. Preferably, the connecting strips 13 are arranged perpendicular to the pivot shaft 21. A hook 14 is provided at the bottom of the bent portion 11. One end of the spring 40 in the lower spring assembly is hooked onto different hooks 14.

[0053] See Figure 3 and Figure 7 As shown, the cam structure 50 includes a working surface 51 on the slide 30 near the pivot shaft 21, and one or more positioning grooves 52 on the working surface 51; a rolling element 22 is provided on the rotating seat 20; when the rotating seat 20 rotates, the rolling element 22 rolls along the working surface 51, and after the rolling element 22 slides into the positioning groove 52, it forces the rotating seat 20 to remain at a set opening angle. In this embodiment, it includes two symmetrical working surfaces 51, and the rolling element 22 consists of two rollers rotatably mounted on the rotating seat 20 via a shaft. When the rotating seat 20 swings relative to the fixed seat 10, the rolling element 22 presses against the working surface 51, forcing the slide 30 to move. The slide 30 applies a limiting force to the rotating seat 20 through a spring 40 in conjunction with the positioning groove 52.

[0054] The cam structure 50 can be a plate-like or block-like body integrally disposed on one side of the slide 30. Preferably, in this embodiment, the slide 30 is detachably provided with a cam block 50a on the side near the pivot shaft 21, and the cam block 50a is provided with the cam structure 50 (i.e., the working surface 51) on the side of the pivot shaft 21.

[0055] See Figure 1 and Figure 5 As shown, this embodiment also includes a mounting base 60, which has a slot. The fixed base 10 and / or the rotating base 20 are slidably inserted into the slot and locked in place by fasteners 61 such as bolts or screws. The slot structure allows adjustment of the mounting position of the fixed base 10 or the rotating base 20, improving installation efficiency. Preferably, the fixed base 10 and / or the rotating base 20 are provided with threaded holes or mounting holes adapted to screws or bolts. Multiple threaded holes or mounting holes are spaced apart along the insertion direction to accommodate multiple mounting positions.

[0056] See Figure 4 and Figure 7 As shown, the slide 30 is preferably detachably provided with guard plates 33 on both sides. The guard plates 33 are fixedly provided on both sides of the slide 30 by rivets or screws. The guard plates 33 are located between the slide 30 and the fixed seat 10. The guard plates 33 act as friction and damping elements, tending to prevent the slide 30 from moving and providing damping force when the rotating seat 20 swings, thereby causing the rotating seat 20 to swing slowly.

[0057] This application also discloses an office device with the above-described pivoting structure, including a main unit and a cover, wherein the cover is pivotally mounted on the main unit. Preferably, the office device is a photocopier or a scanner;

[0058] This utility model effectively increases the force of the spring 40 by setting multiple spring groups, thereby better realizing the temporary limiting function of opening and closing components such as the cover plate.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
