Abstract
Description
Technical Field
[0001] This utility model relates to a document binding device. It falls within the technical field of document binding devices. Background Technology
[0002] Document binding devices are specialized equipment used to organize and secure financial documents for archiving and retrieval. These devices are crucial for the financial management of enterprises and institutions, ensuring not only document security and neatness but also significantly improving work efficiency. Currently, document storage methods include binding and clipping. Binding requires punching holes in the document, which, while preventing detachment after binding, makes disassembly difficult. Clipping uses folders to hold documents; however, existing folders open by pressing a handle, weakening their holding capacity when the folder remains open for extended periods. The open area can also cause compression damage to documents, hindering effective document holding. Furthermore, the short lever arm requires significant force when holding thick documents, potentially causing hand injury. Utility Model Content
[0003] The technical problem to be solved by this utility model is: to solve the above-mentioned technical problem, this utility model provides a document binding device.
[0004] The technical solution adopted by this utility model is: a document binding device, characterized in that: it has a first clamping plate and a second clamping plate, a telescopic rod connecting the first clamping plate and the second clamping plate, the first clamping plate and the second clamping plate can be arranged at the upper and lower positions of the document respectively, a first connecting rod and a second connecting rod are installed at corresponding positions on the first clamping plate and the second clamping plate, a sleeve is provided next to the first clamping plate and the second clamping plate, the first connecting rod and the second connecting rod extend into the sleeve in an inclined direction, and a driving mechanism is provided on the sleeve to drive the ends of the first connecting rod and the second connecting rod that extend into the sleeve to move in the axial direction of the sleeve. Thus, as the drive mechanism moves the end of the connecting rod into the sleeve, the cooperation between the first connecting rod, the second connecting rod, and the end of the sleeve drives the first clamping plate and the second clamping plate to move towards each other, thereby clamping the document placed between the first clamping plate and the second clamping plate. Both the first clamping plate and the second clamping plate are in contact with the document surface, having a large contact area, which makes it less likely to damage the document. The telescopic rod connecting the first clamping plate and the second clamping plate guides the movement of the first clamping plate and the second clamping plate.
[0005] The first connecting rod is hinged to the first clamping plate, and the second connecting rod is hinged to the second clamping plate. Thus, as the drive mechanism moves the first and second connecting rods into the sleeve, the first connecting rod and the first clamping plate, and the second connecting rod and the second clamping plate, can rotate relative to each other, allowing the first and second clamping plates to move towards each other. Simultaneously, the telescopic rod can also limit and tidy up the documents when clamping them.
[0006] The drive mechanism has a stud installed inside the sleeve, which is threaded into the inner wall of the sleeve. The ends of the first connecting rod and the second connecting rod are connected to the stud, and a handle is installed on the end of the stud that extends outside the sleeve. Thus, when a person turns the handle, the stud will rotate, causing the first connecting rod and the second connecting rod to move into the sleeve. This method is convenient and labor-saving.
[0007] An adjusting rod is provided inside the sleeve, arranged along the sleeve's axis. The first end of the adjusting rod is rotatably mounted on the end of the stud. The ends of the first and second connecting rods are both hinged to the second end of the adjusting rod. A locking mechanism is provided between the adjusting rod and the sleeve. Thus, during the threaded engagement of the stud with the sleeve, the adjusting rod moves within the sleeve. The locking mechanism locks the relative position between the adjusting rod and the sleeve, preventing the connecting rod and clamp connected to the adjusting rod from loosening.
[0008] The locking mechanism has a limiting rod arranged radially within the adjusting rod. Both ends of the limiting rod extend beyond the sleeve. A limiting groove is formed on the sleeve at the position where it mates with the first end of the limiting rod, arranged along the moving direction of the adjusting rod. The limiting rod slides into the limiting groove. At least two locking slots are evenly arranged on the sleeve at the position where it mates with the second end of the limiting rod, along the moving direction of the adjusting rod, mate with the limiting rod. Thus, when the limiting rod is pulled towards its first end, the limiting rod disengages from the locking slot, allowing it to slide into the limiting groove. The limiting rod moves synchronously with the adjusting rod, enabling the first and second clamping plates to move towards or away from each other, thereby clamping the document between the first and second clamping plates. When the first and second clamping plates are clamping the document, the adjusting rod moves to the corresponding position. By pulling the limiting rod towards its second end, the limiting rod engages with the locking slot, preventing the adjusting rod from moving and thus preventing the first and second clamping plates from loosening.
[0009] A limit block is installed on the limit rod inside the adjusting rod. A stop block is made on the side wall of the adjusting rod at a position corresponding to the limit block. A spring is fitted onto the limit rod, and the spring is arranged between the limit block and the stop block on one side of the first end of the limit rod. In this way, the cooperation between the limit block and the stop block can effectively prevent the limit rod from falling off. Under the action of the spring, when the adjusting rod moves to the corresponding position, the limit rod will move into the slot to lock. When it is necessary to release the document, by pulling the limit rod towards the first end of the limit rod, the cooperation between the limit rod and the slot can be released. At this time, turning the handle can drive the adjusting rod to move. When the person releases the limit rod, the limit rod will cooperate with the slot under the action of the spring to lock the adjusting rod.
[0010] In this embodiment, a label is made on the handle, which makes it easy to mark the labels to classify the documents and make them easy to find.
[0011] The beneficial effects of this utility model are as follows: This utility model sets up a first clamping plate and a second clamping plate, and respectively sets a first connecting rod and a second connecting rod at corresponding positions on the first clamping plate and the second clamping plate. The first connecting rod and the second connecting rod extend into the same sleeve, and a driving mechanism is set inside the sleeve to drive the first connecting rod and the second connecting rod to move into the sleeve. Thus, when the driving mechanism drives the first connecting rod and the second connecting rod to move into the sleeve, it also drives the first clamping plate and the second clamping plate to move. At this time, under the cooperation of the first connecting rod, the second connecting rod, and the sleeve, and the action of the telescopic rod connecting the first clamping plate and the second clamping plate, the first clamping plate and the second clamping plate move towards each other and clamp the document. This utility model also sets up a stud inside the sleeve that mates with the sleeve's thread, and the stud extends out of the sleeve... A handle is installed at one end, and a rotatable adjusting rod is installed at the end of the stud inside the sleeve. The adjusting rod can move along the axial direction of the sleeve. Both the first connecting rod and the second connecting rod are installed on the adjusting rod. A limit rod is installed on the adjusting rod. Limit grooves and slots are respectively made on the sleeve at the corresponding positions at both ends of the limit rod. When the limit rod is pulled by the operator to move towards the first end of the limit rod, the limit rod and the slot are disengaged, and the adjusting rod can move within the sleeve. When the adjusting rod moves to the point where the first clamping plate and the second clamping plate are engaged to clamp the document, the limit rod is released. At this time, the limit rod will move towards the slot under the action of the spring and engage with the slot. The engagement of the limit rod and the slot will lock the adjusting rod in this position, which can prevent the first clamping plate and the second clamping plate from moving, thereby achieving document clamping.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0018] This embodiment is a binding device for a document 12, having a first clamping plate 9 and a second clamping plate 11 arranged opposite to each other, with a telescopic rod 13 connecting the first clamping plate 9 and the second clamping plate 11. When the first clamping plate 9 and the second clamping plate 11 are arranged on both sides of the document 12 along a direction perpendicular to the document 12, the first clamping plate 9 and the second clamping plate 11 move towards each other to clamp the document 12. At this time, the telescopic rod 13 guides the movement of the first clamping plate 9 and the second clamping plate 11 and also helps to keep the document 12 neat.
[0019] In this embodiment, the first connecting rod 8 is hinged to the first clamping plate 9, and the second connecting rod 10 is hinged to the second clamping plate 11. A sleeve 1 is provided next to the first clamping plate 9 and the second clamping plate 11. The ends of the first connecting rod 8 and the second connecting rod 10 extend into the sleeve 1. A drive mechanism is provided inside the sleeve 1 to drive the first connecting rod 8 and the second connecting rod 10 to move into the sleeve 1. Thus, when the drive mechanism drives the first connecting rod 8 and the second connecting rod 10 to move into the sleeve 1, the cooperation between the first connecting rod 8, the second connecting rod 10 and the sleeve 1, and the action of the telescopic rod 13 connecting the first clamping plate 9 and the second clamping plate 11, can drive the first clamping plate 9 and the second clamping plate 11 to move towards each other.
[0020] In this embodiment, the drive mechanism has a stud 2 installed inside the sleeve 1, the stud 2 being threadedly engaged with the sleeve 1, and a handle 3 installed on the end of the stud 2 extending outside the sleeve 1. Thus, when a person operates the handle 3 and rotates the stud 2, the threaded engagement between the stud 2 and the sleeve 1 causes the stud 2, the first connecting rod 8, and the second connecting rod 10 to move away from the document 12, thereby allowing the first clamping plate 9 and the second clamping plate 11 to clamp the document 12.
[0021] In this embodiment, a label is made on the handle 3, which makes it easy to mark the labels to classify the documents 12 and make them easy to find.
[0022] In this embodiment, an adjusting rod 4 is provided inside the sleeve 1 along the axial direction of the sleeve 1. The first end of the adjusting rod 4 is rotatably mounted on the end of the stud 2, and the ends of the first connecting rod 8 and the second connecting rod 10 are both mounted on the second end of the adjusting rod 4 via hinges.
[0023] In this embodiment, a locking mechanism is provided on the adjusting rod 4. The locking mechanism can lock the position of the adjusting rod 4 when the adjusting rod 4 moves to the corresponding position in the sleeve 1 and the first clamping plate 9 and the second clamping plate 11 cooperate to clamp the document 12, so as to prevent the cooperation between the first clamping plate 9 and the second clamping plate 11 from becoming loose.
[0024] In this embodiment, the locking mechanism has a limiting rod 5 arranged in the adjusting rod 4 radially. Both ends of the limiting rod 5 can extend out of the sleeve 1. A limiting groove 6 arranged in the moving direction of the adjusting rod 4 is formed at the position on the sleeve 1 that cooperates with the first end of the limiting rod 5. The limiting rod 5 and the limiting groove 6 are slidably engaged. At least two slots 7 that cooperate with the limiting rod 5 are evenly arranged at the position on the sleeve 1 that cooperate with the second end of the limiting rod 5 in the moving direction of the adjusting rod 4. Thus, by pulling the limiting rod 5 towards its first end, the limiting rod 5 and the slot 7 are disengaged. At this time, the limiting rod 5 can slide into the limiting groove 6. The limiting rod 5 can move synchronously with the adjusting rod 4, realizing that the first clamping plate 9 and the second clamping plate 11 move towards or away from each other, thereby enabling the first clamping plate 9 and the second clamping plate 11 to clamp the document 12. When the first clamping plate 9 and the second clamping plate 11 are clamping the document 12, the adjusting rod 4 moves to the corresponding position. By pulling the limiting rod 5 towards its second end, the limiting rod 5 engages with the slot 7, preventing the adjusting rod 4 from moving and thus preventing the first clamping plate 9 and the second clamping plate 11 from becoming loose.
[0025] A limiting block 14 is installed on the limiting rod 5 inside the adjusting rod 4. A stop block 16 is made on the side wall of the adjusting rod 4 at a position corresponding to the limiting block 14. A spring 15 is fitted on the limiting rod 5, and the spring 15 is arranged between the limiting block 14 and the stop block 16 on one side of the first end of the limiting rod 5. Thus, under the action of the spring 15, when the adjusting rod 4 moves to the corresponding position, the limiting rod 5 will move towards the slot 7 to achieve locking. When it is necessary to release the document 12, by pulling the limiting rod 5 towards the first end of the limiting rod 5, the engagement between the limiting rod 5 and the slot 7 can be released. At this time, turning the handle 3 can drive the adjusting rod 4 to move. When the person releases the limiting rod 5, the limiting rod 5 will engage with the slot 7 under the action of the spring 15 to achieve locking of the adjusting rod 4. The cooperation of the limiting block 14 and the stop block 16 can effectively prevent the limiting rod 5 from falling off.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
