Description

Technical Field

[0001] This utility model relates to the field of document binding technology, specifically to a document binding punching device. Background Technology

[0002] In office settings, document management, and financial document organization, document binding is a crucial step in ensuring the standardized storage and easy access of information. Punching, as a core preliminary step in the binding process, directly impacts overall work efficiency in terms of efficiency and convenience. Currently, document binding punching equipment on the market is mainly divided into two categories: electric and manual. While electric equipment offers higher punching efficiency, it suffers from drawbacks such as larger size, reliance on power supplies, and higher procurement and maintenance costs, limiting its applicability in small office settings, temporary work locations, or mobile operations. Manual punching equipment, on the other hand, is the preferred choice for most small and medium-sized enterprises, individual office workers, and home office users due to its compact size, lack of power requirements, and lower cost.

[0003] Most existing manual drilling machines use a rotating rod to directly press a guide rod, which then indirectly pushes the punch head to complete the drilling action. Because the downward pressure of the rotating rod is angled in the transmission path between the rotating rod and the guide rod, this angled force generates a lateral component when transmitted to the punch head, resulting in a significant dispersion of the effective vertical drilling force. In actual operation, operators need to apply greater downward pressure to drive the punch head through the document, especially when processing thicker documents, where the problem of arduous operation is more pronounced. Prolonged use can easily lead to hand fatigue and reduced work efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a punching device for document binding.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] Document binding punching equipment, including:

[0007] Support components are used to hold the documents to be punched;

[0008] A vertical guide tube rotating rod is inclinedly mounted on a support member, and the lower end of the vertical guide tube rotating rod is rotatably connected to the support member;

[0009] An arc-shaped guide rod is fixed to the rotating rod of the vertical guide tube, and the center of the arc-shaped guide rod is the rotation point of the rotating rod of the vertical guide tube and the support component;

[0010] A guide member, fixed to the support member, is used to guide the arc-shaped guide rod, and includes:

[0011] An arc-shaped guide tube, the center of which is the rotation point of the vertical guide tube rotating rod and the support, and the end of the arc-shaped guide rod away from the vertical guide tube rotating rod is inserted into the arc-shaped guide tube;

[0012] A vertical guide tube is fixedly connected to the bottom end of an arc-shaped guide tube;

[0013] A punching head, the top of which is inserted into the vertical guide tube, and the bottom of which is used for punching holes;

[0014] A return spring, mounted on the punch head, is used to drive the punch head to move upward.

[0015] The transmission ball is located inside the guide component and between the arc-shaped guide rod and the punching head;

[0016] in:

[0017] When the vertical guide tube rotating rod is pressed down, the downward pressure is concentrated on the drilling head due to the transmission of the transmission ball.

[0018] Preferably, the angle between the tangent of the end of the arc-shaped guide tube away from the vertical guide tube and the vertical plane is between 30° and 45°.

[0019] Preferably, when the drilling head is driven to press down to drill a hole by the rotating rod of the vertical guide tube, the maximum height of the drilling head descent is not less than 5cm.

[0020] Preferably, the support includes a base, and a clearance hole is provided in the base and directly below the punch head, through which the punch head can pass when it moves downward.

[0021] Preferably, a raised plate is fixed on the base, a fixed frame is fixed on the raised plate, and the guide is fixed on the fixed frame.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] The core innovation of this invention lies in the addition of a transmission ball and the optimization of the mating structure between the arc-shaped guide rod and the guide component. When the vertical guide tube is pressed down, the arc-shaped guide rod moves along the fixed trajectory of the arc-shaped guide tube, and the resulting tilting force is directly transmitted to the punching head through the transmission ball. The transmission ball can convert the component force in the tilting direction into effective pressure in the vertical direction, avoiding the dispersion and waste of force during transmission. Actual testing shows that when processing 30-page documents, the operator's required downward pressure is reduced compared to existing equipment, significantly reducing hand fatigue and improving single-punch efficiency and continuous operation capability.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0030] Example

[0031] like Figure 1-3 As shown, a document binding punching device includes:

[0032] Support 1 is used to hold the document to be punched;

[0033] The vertical guide tube rotating rod 3 is inclinedly set on the support member 1, and the lower end of the vertical guide tube rotating rod 3 is rotatably connected to the support member 1;

[0034] The arc-shaped guide rod 31 is fixed on the vertical guide tube rotating rod 3, and the center of the arc-shaped guide rod 31 is the rotation point of the vertical guide tube rotating rod 3 and the support member 1.

[0035] Guide member 2, fixed to support member 1, is used to guide the arc-shaped guide rod 31, and includes:

[0036] The arc-shaped guide tube 21 has its center at the rotation point of the vertical guide tube rotating rod 3 and the support member 1, and the end of the arc-shaped guide rod 31 away from the vertical guide tube rotating rod 3 is inserted into the arc-shaped guide tube 21.

[0037] The vertical guide tube 22 is fixedly connected to the bottom end of the arc-shaped guide tube 21;

[0038] The punch head 4 has its top end inserted into the vertical guide tube 22 and its bottom end used for punching holes. The support member 1 includes a base 11. The base 11 has a clearance hole 12 that can pass through when the punch head 4 moves downward. A shim plate 13 is fixed on the base 11, and a fixing frame 14 is fixed on the shim plate 13. The guide member 2 is fixed on the fixing frame 14.

[0039] The return spring 5 is mounted on the punch head 4 and is used to drive the punch head 4 to move upward.

[0040] The transmission ball 6 is located inside the guide member 2 and between the arc-shaped guide rod 31 and the punch head 4;

[0041] in:

[0042] When the vertical guide tube rotating rod 3 is pressed down, the downward pressure is concentrated on the drilling head 4 due to the transmission of the transmission ball 6.

[0043] Specifically, existing document binding punching equipment typically uses a vertical guide tube rotating rod 3 to directly compress an arc-shaped guide rod 31, which then indirectly acts on the punching head 4. During this process, because the compressive force of the vertical guide tube rotating rod 3 is oblique, the force is dispersed after being transmitted to the punching head 4 through the arc-shaped guide rod 31. The vertical separation of the downward compressive force of the vertical guide tube rotating rod 3 is roughly the force acting on the punching head 4, resulting in a significant waste of force. This invention addresses this issue by... The tilting force on the arc-shaped guide rod 31 is directly transmitted to the punching head 4 through the transmission ball 6. At this time, the force is not dispersed in large quantities. The force acting on the arc-shaped guide rod 31 is concentrated on the punching head 4 through the transmission ball 6, so that the punching head 4 has a greater punching force and the operator saves effort. In this utility model, by setting the transmission ball 6, it can not only play a guiding role, but also make the force of pressing down the vertical guide tube rotating rod 3 directly act on the punching head 4, avoiding the dispersion of force and solving the problem of saving effort.

[0044] Furthermore, the angle between the tangent of the end of the arc-shaped guide tube 21 away from the vertical guide tube 22 and the vertical plane is between 30° and 45°.

[0045] Specifically, based on the core mechanism of this equipment, "transmission ball 6 converts tilting force into vertical pressure," a 30°-45° angle range can achieve "efficient transmission and low-loss conversion" of tilting force. If the included angle is less than 30°, the movement trajectory of the arc-shaped guide rod 31 is closer to the vertical direction. Although the lateral component of the force is reduced, it will lead to a significant increase in the downward stroke of the rotating rod 3—the operator needs to press a longer distance to drive the drilling head 4 to complete effective drilling, which will reduce the operating efficiency. If the included angle is greater than 45°, the tilt of the arc-shaped guide rod 31 will increase significantly. At this time, the proportion of the lateral component of the tilting force increases. Even if it is converted by the transmission ball 6, some force will still be consumed by friction on the inner wall of the guide tube, resulting in a decrease in the effective drilling force in the vertical direction, weakening the core advantage of "efficiency saving." The 30°-45° included angle range can balance the "stroke length" and "force loss", enabling the transmission ball 6 to efficiently convert the tilting force of the arc guide rod 31 into the vertical pressure of the punch head 4. This ensures that when processing 20-30 page thick documents, the downward pressure required by the operator is reduced by 30%-40% compared to existing equipment, truly achieving "effort-saving and travel-saving".

[0046] Furthermore, when the vertical guide tube rotating rod 3 drives the drilling head 4 to press down and drill, the maximum height at which the drilling head 4 descends is not less than 5cm;

[0047] Specifically, in office settings, document binding often involves organizing multiple pages of paper, such as 20-50 page contracts, documents, and reports. These thick documents, when stacked, typically reach a thickness of 3-4 cm. If the maximum drop height of the punch head 4 is less than 5 cm, the problem of "the punch head not being able to fully penetrate the document" will occur—for example, only penetrating the top 10-15 pages, leaving the bottom pages unpunched, preventing proper binding. The 5 cm minimum drop height design covers the stack thickness of most thick documents, ensuring that the punch head 4 can penetrate from the top to the bottom. Even with a 50-page document approximately 4.5 cm thick, it can still achieve complete punching, avoiding "half-hole" or "missing hole" problems caused by insufficient height. This significantly improves the device's adaptability to documents of different thicknesses, eliminating the need for frequent document splitting and multiple punching operations, thus improving binding efficiency.

[0048] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
