Description

Technical Field

[0001] This utility model relates to the field of electricity bill collection, and in particular to an electricity bill collection calculation device. Background Technology

[0002] An electricity bill calculation device is a device used to calculate electricity bills quickly. It is used by power companies for electricity bill collection, helping staff to calculate electricity bills quickly and accurately, and conveniently deliver electricity bills to customers.

[0003] The existing electricity bill collection and calculation device does not have an auxiliary cutting structure for electricity bills, so it cannot cut the electricity bills. This may result in the bills being torn crookedly or damaged when torn, affecting the flatness of the bills.

[0004] Therefore, addressing the issue that existing electricity bill payment calculation devices lack an auxiliary cutting structure for electricity bills, making it impossible to cut the bills and potentially causing them to tear crookedly or become damaged, a new electricity bill payment calculation device can be designed. This device incorporates a lever; sliding the lever left and right causes the blade to slide synchronously, thus cutting the electricity bill roll and improving the flatness of the torn bill. The positioning groove further enhances the smoothness of the lever's movement. A connecting rope is wound around the outer surface of the reset shaft, with one end of the rope tied to the blade. Upon releasing the lever, the reset shaft automatically resets and rotates, causing the connecting rope to pull the blade and lever back to their original positions for the next cut. Utility Model Content

[0005] In order to overcome the problem that the existing electricity bill collection and calculation device does not have an auxiliary cutting structure for electricity bills, and cannot cut the electricity bills, which may result in crooked or damaged bills when they are torn open.

[0013] Preferably, a pencil groove is provided on the right side surface of the calculator body, and two symmetrical arc-shaped grippers are installed on the left side of the inner surface of the pencil groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a toggle block, the blade can slide synchronously when the toggle block slides left and right, thereby cutting the electricity bill roll and improving the flatness of tearing the electricity bill. The positioning groove can improve the smoothness of the toggle block sliding. The outer surface of the reset shaft is wrapped with a connecting rope, one end of which is tied to the blade. So when the toggle block is released, the reset shaft will automatically reset and rotate, driving the connecting rope to pull the blade and toggle block to reset, so as to facilitate the next cut.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of an electricity bill collection and calculation device, including a calculator body 1; it also includes a fixed base 6, a second through groove 7, a sliding groove 8, a blade 9, a lever 10, a positioning groove 11, a circular groove 12, and a reset rotating shaft 13. A mounting groove 2 is provided on the front side of the upper surface of the calculator body 1, and a clamping component is provided inside the mounting groove 2. A sliding cover 4 is slidably connected to the upper surface of the calculator body 1 corresponding to the mounting groove 2. A first through groove 5 is provided on the rear side of the upper surface of the sliding cover 4. A fixed base 6 is provided on the upper surface of the sliding cover 4 corresponding to the first through groove 5. A second through groove 7 is provided on the upper surface of the fixed base 6 corresponding to the first through groove 5. A sliding groove 8 is provided through the middle of the front side surface of the fixed base 6, and a blade 9 is slidably connected inside the sliding groove 8. A lever 10 is provided on the front side surface of the blade 9. The fixed base 6... Positioning grooves 11 are provided on both the upper and lower sides of the front surface of the slide groove 8. The toggle block 10 is engaged with the positioning groove 11 and slides. A circular groove 12 is provided on the left side of the front surface of the fixing base 6. A reset shaft 13 is rotatably connected to the rear side of the inner surface of the circular groove 12. The reset shaft 13 is connected to the blade 9 through an external connecting rope. By setting the toggle block 10, the blade 9 can be driven to slide synchronously when the toggle block 10 is slid left and right, so as to cut the electricity bill roll and improve the flatness of tearing the electricity bill. The positioning groove 11 can improve the smoothness of the toggle block 10 sliding. The outer surface of the reset shaft 13 is wrapped with a connecting rope. One end of the connecting rope is tied to the blade 9. So after the toggle block 10 is released, the reset shaft 13 will automatically reset and rotate, driving the connecting rope to pull the blade 9 and the toggle block 10 to reset, so as to facilitate the next cutting.

[0025] Please see Figures 1-5In this embodiment, damping grooves 14 are provided on both the left and right sides of the upper surface of the calculator body 1, located in the mounting groove 2. Damping blocks 15 are installed on the bottom surface of the sliding cover 4 at positions corresponding to the damping grooves 14. The damping blocks 15 are slidably connected to the damping grooves 14. By setting the damping blocks 15 and the damping grooves 14, the sliding cover 4 can be quickly installed and is not easy to slip off after installation. A groove 16 is provided on the front surface of the calculator body 1, and a magnetic absorbing piece 17 is provided inside the groove 16. Anti-slip pads 18 are provided on both the left and right sides of the upper surface of the sliding cover 4. By setting the magnetic absorbing piece 17, it can be attracted to the iron piece on the sliding cover 4, further enhancing the positioning effect of the sliding cover 4. Furthermore, by setting the protective pads, it can... To increase friction with the hand and facilitate the sliding cover 4 to be slid open, the clamping assembly includes a spring 31, a clamping plate 32, and a bearing 33. Two symmetrical springs 31 are provided on the left and right sides of the inner surface of the mounting groove 2. The other end of the spring 31 is connected to the clamping plate 32. The end of the clamping plate 32 away from the corresponding spring 31 is embedded with the bearing 33. By setting the spring 31, when installing the paper roll, the shaft at one end of the paper roll can be inserted into the bearing 33 on one side. At this time, the corresponding clamping plate 32 is squeezed, which drives the spring 31 to contract, thereby opening up the space for the paper roll to be put in. Then, the shaft at the other end of the paper roll is connected to the corresponding bearing 33 to complete the installation of the paper roll.

[0026] Please see Figures 1-5 In this embodiment, the clamping assembly further includes limiting blocks 34 and limiting grooves 35. Limiting blocks 34 are installed on both the front and rear surfaces of the clamping plate 32. Limiting grooves 35 are formed on both the front and rear sides of the inner surface of the mounting groove 2, corresponding to the positions of the limiting blocks 34. The limiting blocks 34 and limiting grooves 35 are slidably connected. By setting the limiting blocks 34 and limiting grooves 35, when the clamping plate 32 moves, the limiting blocks 34 will slide synchronously inside the limiting grooves 35, thereby improving the stability of the clamping plate 32's movement. Two rotatably connected components are located on the rearward position of the upper surface of the calculator body 1. A symmetrical damping shaft 19 is provided, and a pressure rod 20 is provided on the outer surface of the damping shaft 19. By setting the damping shaft 19 and the pressure rod 20, when filling out the electricity bill, the pressure rod 20 can be pushed upward and rotated to press down the electricity bill and prevent the electricity bill from being rolled up and wrinkled when filling it out. A pencil slot 21 is provided on the right side surface of the calculator body 1. Two symmetrical arc-shaped claws 22 are installed on the left side of the inner surface of the pencil slot 21. By setting the pencil slot 21 and the arc-shaped claws 22, it is easy to hold the pencil and improve convenience.

[0027] During operation, the damping block 15 and damping groove 14 facilitate quick installation of the sliding cover 4 and prevent slippage after installation. The magnetic suction piece 17 attracts the iron piece on the sliding cover 4, further enhancing its positioning effect. The protective pad increases friction with the hand, making it easier for the operator to slide the sliding cover 4 open. The spring 31 allows the shaft at one end of the paper roll to be inserted into the bearing 33 during installation. This compresses the corresponding clamping plate 32, causing the spring 31 to contract and thus opening up space for the paper roll. Then, the other end of the paper roll is connected to the corresponding bearing 33 to complete the installation of the paper roll. By setting the limiting block 34 and the limiting groove 35, the limiting block 34 will slide synchronously inside the limiting groove 35 when the clamping plate 32 moves, thereby improving the stability of the movement of the clamping plate 32. By setting the damping rotating shaft 19 and the pressure rod 20, when filling in the electricity bill, the pressure rod 20 can be pushed up and rotated to press down the electricity bill, avoiding the phenomenon of the electricity bill being rolled up and wrinkled when filling in. By setting the pencil groove 21 and the arc-shaped gripper 22, it is easy to hold the pencil, which improves the convenience.

[0028] Through the above steps, by setting the lever 10, the blade 9 can be driven to slide synchronously when the lever 10 slides left and right, thereby cutting the electricity bill roll and improving the flatness of tearing the electricity bill. When cutting, the paper is not completely cut, but a corner is left to facilitate the subsequent paper being pulled out. The positioning groove 11 can improve the smoothness of the sliding of the lever 10. The outer surface of the reset shaft 13 is wrapped with a connecting rope, one end of which is tied to the blade 9. So when the lever 10 is released, the reset shaft 13 will automatically reset and rotate, driving the connecting rope to pull the blade 9 and the lever 10 to reset, so as to facilitate the next cutting. This solves the problem that the existing electricity bill collection and calculation device does not have an auxiliary cutting structure for electricity bills, and cannot cut the electricity bills, which may cause the electricity bills to be torn crookedly or damaged when torn.
