Description

Technical Field

[0001] This utility model relates to the field of bill binding, and in particular to a novel bill binding device. Background Technology

[0002] An existing patent (publication number: CN214871008U) discloses a cutting device for binding accounting invoices, including a base plate. A groove is provided on the side of the base plate, and a pulley is installed inside the groove. A limit rod is held inside the pulley, and a connecting block is fixedly installed at the top of the limit rod. A strip rod is movably connected to the top of the connecting block, and a strip groove is provided on the side of the strip rod. A slider is held inside the strip groove, and a fixing rod is fixedly installed on the outer surface of the slider. A cutting blade is located below the fixing rod. An arc-shaped slide rail is provided on the other side of the base plate near the corner, and a locking block is held inside the arc-shaped slide rail. However, this device does not compress the invoices by the upper structure when binding them, which easily leads to misalignment of the invoices during operation. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a second spring that uses the upper plate of the sliding rod as support to apply a downward pushing force to the pressure plate, thereby pressing the pressure plate firmly onto the documents. This prevents misalignment caused by movement during punching during bill binding. This elastic pressing structure can be used on documents of different thicknesses, making it a novel bill binding device that is relatively convenient to use.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A novel bill binding device includes a protective cover, a rectangular base, a vertical slide tube, a fixing frame, a fixing connecting plate, a vertical guide rod, a No. 1 spring, a U-shaped connecting plate, a rotating pressure plate, a side baffle, and a pressure plate. The lower part of the side baffle has a lower baffle plate, the lower surface of which is in contact with the rectangular base. The lower part of the lower baffle plate has a trapezoidal slider, which is symmetrically arranged on the lower part of the lower baffle plate. The rectangular base has a trapezoidal groove, which is adapted to the trapezoidal slider. The trapezoidal slider is inserted into the trapezoidal groove and slides within it. A magnetic sheet is embedded in the rectangular base, and the lower surface of the lower baffle plate is in contact with the upper surface of the magnetic sheet. The lower part of a positioning slide rod is connected to the rectangular base, passes through the pressure plate, and slides within it. Two sets of positioning slide rods are symmetrically arranged at both ends of the pressure plate.

[0006] The upper part of the positioning slide rod is connected to the upper slide rod plate. The second spring is sleeved on the positioning slide rod. The upper part of the second spring abuts against the upper slide rod plate, and the lower part of the second spring abuts against the side plate of the pressure plate. The pressure plate has a punching knife clearance hole. The upper part of the punching knife is inserted into the lower seat of the slide tube. The punching knife is inserted into the punching knife clearance hole. The shim is placed inside the rectangular base and is placed below the punching knife.

[0007] The lower part of the fixed frame is connected to a rectangular base, and the side of the fixed frame has a fixed frame side plate. A set of fixed frame side plates are distributed on the side of the fixed frame. A vertical slide tube is inserted into the fixed frame side plate and slides up and down inside the fixed frame side plate. The upper part of the vertical slide tube is connected to an upper circular baffle, and the lower surface of the upper circular baffle is in contact with the fixed frame side plate.

[0008] The fixed connecting plate is connected to the outside of the vertical slide tube. The lower part of the vertical guide rod is connected to the side plate of the fixed frame. The upper part of the vertical guide rod passes through the fixed connecting plate and slides inside the fixed connecting plate. The first spring is sleeved on the vertical guide rod. The upper part of the first spring abuts against the side plate of the fixed connecting plate, and the lower part of the first spring abuts against the side plate of the fixed frame. The side of the fixed frame is connected to a U-shaped connecting plate. The rotating pressure plate is inserted into the U-shaped connecting plate and connected to the U-shaped connecting plate through a rotating shaft. Beneficial effects

[0009] 1. The lower part of the fixing frame of this utility model is fixed on a rectangular base. A set of fixing frame side plates are sleeved on the vertical slide tube and supported by an upper circular baffle. This prevents the vertical slide tube from sliding downwards out of the fixing frame side plates during bill binding. When the lower surface of the upper circular baffle is in contact with the lower part of the fixing frame side plate, the height of the lower part of the vertical slide tube is at its lowest downward position. A fixing connecting plate is installed and fixed on the outside of the vertical slide tube. A vertical guide rod guides a first spring. The first spring, supported by the fixing frame side plates, applies an upward thrust to the fixing connecting plate, causing the vertical slide tube to move upwards. When in use, the upper part of the punching knife is inserted into the magnetic hole at the bottom of the slide tube base. The vertical slide tube moves downward, driving the punching knife downward to punch the documents stacked on top of the rectangular base. The vertical slide tube is designed with an automatic spring-loaded structure. After punching, the punching knife is automatically pulled out from the document, making it easy to operate. The U-shaped connecting plate is installed and fixed on the side of the fixed frame. The U-shaped connecting plate supports the rotating pressure plate through the rotating shaft. The rotating pressure plate can rotate on its own. When in use, you can hold the handle and press down to make the rotating pressure rod press the horizontal side block downward, so that the vertical slide tube moves downward and the punching knife punches the document.

[0010] 2. The protective cover of this utility model protects the punching components on the outside of the vertical slide tube while making the entire outer tube of the device look simpler and more beautiful. The trapezoidal slider is inserted into the trapezoidal slide groove, so that the lower surface of the baffle plate is in close contact with the rectangular base, ensuring the verticality of the side baffle plate and preventing the side baffle plate from tilting during bill binding. The lower surface of the baffle plate is in contact with the magnetic sheet. This magnetically connected structure positions the side baffle plate during use and prevents the side baffle plate from sliding arbitrarily during bill binding. The side baffle plate pushes the front of the bill to be aligned, ensuring the neatness of the front of the bill. The positioning slide rod passes through the second spring and the pressure plate and connects to the rectangular base. The second spring, supported by the upper piece of the slide rod, applies a downward pushing force to the pressure plate, making the pressure plate press the bill firmly. This prevents the bill from shifting during punching and causing misalignment. This elastic pressing structure can be used for bills of different thicknesses and is more convenient to use. The gasket protects the lower cut surface of the punching knife, preventing the lower part of the punching knife from colliding with the rectangular base and causing damage to the lower part of the punching knife when it punches through the bill during bill binding.

The side baffle 19 has a lower baffle plate 20 at its lower part, and the lower surface of the lower baffle plate 20 is in contact with the rectangular base 05. The lower part of the lower baffle plate 20 has a trapezoidal slider 31, which is symmetrically arranged at the lower part of the lower baffle plate 20. The rectangular base 05 has a trapezoidal groove 21, and the trapezoidal slider 31 is adapted to the trapezoidal groove 21. The trapezoidal slider 31 is inserted into the trapezoidal groove 21, causing the lower surface of the lower baffle plate 20 to... The side baffle 19 is tightly attached to the rectangular base 05 to ensure its verticality and prevent it from tilting during bill binding. The trapezoidal slider 31 slides within the trapezoidal groove 21. The magnetic sheet 29 is embedded in the rectangular base 05. The lower surface of the baffle lower plate 20 is in contact with the upper surface of the magnetic sheet 29. This magnetically connected structure positions the side baffle 19 during use and prevents it from sliding arbitrarily during bill binding. The side baffle 19 aligns the front of the bill, ensuring the neatness of the front of the bill. The lower part of the positioning slide rod 26 is connected to the rectangular base 05. The positioning slide rod 26 passes through the pressure plate 22 and slides within the pressure plate 22. Two sets of positioning slide rods 26 are symmetrically arranged at both ends of the pressure plate 22.

[0019] Example 2:

[0020] The positioning slide rod 26 of this utility model is connected to the upper slide rod plate 28 at its upper part. A second spring 27 is sleeved on the positioning slide rod 26. The upper part of the second spring 27 abuts against the upper slide rod plate 28, and the lower part of the second spring 27 abuts against the side plate of the pressure plate 22. The positioning slide rod 26 passes through the second spring 27 and the pressure plate 22 and connects to the rectangular base 05. The second spring 27, supported by the upper slide rod plate 28, applies a downward pushing force to the pressure plate 22, causing the pressure plate 22 to press the document firmly. This prevents the document from shifting during punching and causing misalignment during bill binding. This elastic pressing structure can be used for documents of different thicknesses and is relatively convenient to use. The pressure plate 22 has a punching knife clearance hole 25, and the upper part of the punching knife 24 is inserted into the slide rod. When in use, the upper part of the punching knife 24 is inserted into the magnetic hole at the bottom of the tube lower seat 07. The vertical slide tube 06 moves downward to drive the punching knife 24 downward to punch the documents stacked on top of the rectangular base 05. The vertical slide tube 06 is set with an automatic spring-loaded structure. After punching, the punching knife 24 is automatically pulled out from the document, which is convenient to operate. The punching knife 24 is inserted into the punching knife clearance hole 25. The shim 23 is placed inside the rectangular base 05 and below the punching knife 24. The shim 23 protects the lower cut surface of the punching knife 24 and prevents it from colliding with the rectangular base 05 and causing damage to the lower part of the punching knife 24 when it punches through the document during the binding of the bill.
