Description

Technical Field

[0001] This utility model relates to the field of construction engineering tools, specifically to an ink line. Background Technology

[0002] The ink line is a core tool in the traditional Chinese woodworking industry. It is mainly used for marking straight lines and measuring. Its history can be traced back to the Spring and Autumn Period. Legend has it that it was invented by Lu Ban. When building a column or wall on a construction site, control lines need to be marked with an ink line beforehand. Then, steel bars are tied and formwork is installed to ensure that the building is built to its original size and position without deviation, thus ensuring the safety and quality of the building.

[0003] The self-made ink fountain disclosed in the existing patent publication number CN220007793U collects the ink residue on the liner through the ink-absorbing sponge in the collection component, and recycles the collected ink from the return channel to the second box, thus avoiding excessive ink residue on the liner and causing ink waste; at the same time, the collection component and the take-up component are set in different cavities to avoid the take-up compartment from causing great pollution.

[0004] In the aforementioned patent, residual ink is absorbed by the yarn passing between the ink-absorbing sponges. However, the outside of the yarn is easily contaminated with external impurities. As the yarn passes through the ink-absorbing sponges, friction occurs. Furthermore, the ink-absorbing sponges absorb ink for a long time, leading to wear and tear after prolonged use, requiring replacement. However, neither the first nor the second cartridge can be quickly disassembled, making it inconvenient to replace the ink-absorbing sponges and reducing the convenience of maintenance. Additionally, the take-up roller lacks a limiting mechanism, making it prone to movement and affecting the winding stability of the yarn. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing an ink fountain that facilitates maintenance by switching on and off, and provides a limit switch to ensure stable wire take-up.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ink fountain includes a box body, a middle partition and a front partition fixedly connected to the box body. A switch assembly is movably installed on the top of the box body. An ink-absorbing sponge and a winding roller are movably installed inside the box body. The winding roller is located behind the ink-absorbing sponge, and a wire is provided outside the winding roller. A limit assembly is fixedly installed at the rear of the box body. The switch assembly includes an alignment plate, which is fixedly installed on the top of the middle partition. A front cover plate and a rear cover plate are movably hinged to the front and rear sides of the top of the box body, respectively. A guide groove is provided on the top of the front cover plate. Corresponding limit holes are provided inside the alignment plate, the front cover plate, and the rear cover plate. A slider is movably engaged inside the guide groove. A rod located in the limit hole is fixedly installed inside the slider. A support spring located in front of the slider is movably sleeved outside the rod. A pressure plate is fixedly installed on the top of the guide groove, and a lever is fixedly installed outside the slider.

[0007] Preferably, the size of the insertion rod corresponds to that of the limiting hole, and the insertion rod passes through the limiting hole provided on the alignment plate, the front cover plate, and the rear cover plate.

[0008] Preferably, the guide groove is located on the top of the front cover plate and is symmetrically arranged on the left and right sides, and the lever is fixedly installed between the two side sliders.

[0009] Preferably, the top of the box body is movably snapped with a sealing strip located below the front cover plate, and the top of the front cover plate is fixedly connected with a feeding port.

[0010] Preferably, the alignment plate is located in the middle of the box body, the front partition is located at the front of the box body, the ink-absorbing sponge is placed on the front and rear sides of the front partition, the winding roller and the limiting component are both located on the rear side of the middle partition, and the box body, the middle partition and the front partition are all provided with openings for the wire to pass through, and the wire passes through the inside of the ink-absorbing sponge.

[0011] Preferably, the outer side of the winding roller is provided with a hexagonal slot, and the limiting component includes a guide sleeve fixedly installed inside the box body. The guide sleeve is movably engaged with a rotating shaft that penetrates the side wall of the box body. The rotating shaft is movably sleeved with a support spring II located inside the guide sleeve. A stop plate is fixedly connected to the outer side of the rotating shaft, and a connecting plate is fixedly installed to the outer side of the rotating shaft.

[0012] Preferably, a fixing bolt is movably mounted on the outer side of the connecting plate, and the fixing bolt is threaded into the inside of the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By pushing the lever forward, the slider slides forward in the guide groove, which simultaneously moves the insertion rod forward. The rear end of the insertion rod will move out of the limiting holes of the rear cover plate and the alignment plate. Then, the front cover plate and the rear cover plate are flipped along the hinge with the cartridge body to open the cartridge body. The operation is quick and convenient, making it easy to replace the ink-absorbing sponge and improving the convenience of maintenance.

[0015] 2. Pulling the connecting plate causes the rotating shaft and the second support spring to move outward, and the second support spring is squeezed. Then, rotate the connecting plate to the hexagonal slot to release the connecting plate, so that the elastic force of the second support spring pushes the rotating shaft and the connecting plate inward. The hexagonal head is inserted into the hexagonal slot, which restricts the rotation of the winding roller, realizes the limit function, and ensures the stable winding of the wire.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: an ink fountain, comprising a box body 1, a middle partition 2 and a front partition 3 fixedly connected inside the box body 1; a switch assembly 4 is movably installed on the top of the box body 1; an ink-absorbing sponge 5 and a winding roller 6 are movably installed inside the box body 1, the winding roller 6 is located behind the ink-absorbing sponge 5, and a wire 7 is provided outside the winding roller 6; a limit assembly 8 is fixedly installed at the rear inside the box body 1; the switch assembly 4 includes an alignment plate 41, which is fixedly installed on the top of the middle partition 2; a front cover plate 42 and a rear cover plate 43 are movably hinged to the front and rear sides of the top of the box body 1, respectively; a guide groove 44 is provided on the top of the front cover plate 42; and corresponding limit holes 45 are provided inside the alignment plate 41, the front cover plate 42, and the rear cover plate 43. The guide groove 44 is internally connected to a slider 47, and the slider 47 is internally fixedly installed with a rod 46 located in a limiting hole 45. The rod 46 is externally connected to a support spring 48 located in front of the slider 47. A pressure plate 49 is fixedly installed on the top of the guide groove 44, and a lever 410 is fixedly installed on the outside of the slider 47. By pushing the lever 410 forward, the slider 47 slides forward in the guide groove 44, and the rod 46 moves forward simultaneously. The rear end of the rod 46 moves out from the limiting hole 45 of the rear cover plate 43 and the alignment plate 41. Then the front cover plate 42 and the rear cover plate 43 are flipped along the hinge with the cartridge 1, thereby opening the cartridge 1. The operation is quick and convenient, making it easy to replace the ink-absorbing sponge 5 and improving the convenience of maintenance.

[0024] The size of the insertion rod 46 corresponds to that of the limiting hole 45. The insertion rod 46 passes through the limiting hole 45 provided on the alignment plate 41, the front cover plate 42, and the rear cover plate 43. The insertion rod 46 provided in the limiting hole 45 can be positioned in the alignment plate 41, the front cover plate 42, and the rear cover plate 43 to achieve the effect of limiting and fixing. At the same time, the alignment plate 41 and the rear cover plate 43 can be removed for release, making it convenient to open the front cover plate 42 and the rear cover plate 43. The operation is convenient and quick.

[0025] The guide groove 44 is located on the top of the front cover plate 42 and is symmetrically arranged on the left and right. The lever plate 410 is fixedly installed between the two sliders 47. The symmetrical arrangement ensures that the sliders 47 on both sides remain synchronized and stable during movement, avoiding the situation where one side slides while the other side gets stuck. Pushing the lever plate 410 causes the insert rods 46 on both sides to move out of the limiting holes 45 of the rear cover plate 43 and the alignment plate 41 at the same time, ensuring that the front cover plate 42 and the rear cover plate 43 can be flipped open smoothly and evenly, enhancing the stability of the overall device.

[0026] The top of the cartridge 1 is movably connected to a sealing strip located below the front cover plate 42. The top of the front cover plate 42 is fixedly connected to a filling port 411, which facilitates the addition of ink. The staff can directly inject ink into the cartridge 1 through the filling port 411. The front cover plate 42 presses the sealing strip to effectively prevent ink leakage and ensure the airtightness of the cartridge 1.

[0027] Please see Figure 2 and Figure 4 The alignment plate 41 is located in the middle of the box body 1, the front partition 3 is located in the front of the box body 1, the ink-absorbing sponge 5 is placed on the front and back sides of the front partition 3 respectively, the winding roller 6 and the limiting component 8 are both located on the back side of the middle partition 2. The box body 1, the middle partition 2 and the front partition 3 are all provided with openings for the wire 7 to pass through. The wire 7 passes through the inside of the ink-absorbing sponge 5. The two sets of ink-absorbing sponges 5 set at the front and back ensure that the wire 7 can fully absorb ink during the process of passing through, and ensure that the surface of the wire 7 is evenly dipped in ink and absorbs ink. The winding roller 6 can perform the winding operation on the wire 7.

[0028] Please see Figure 2 and Figure 5 The winding roller 6 has a hexagonal slot 61 on its outer side. The limiting component 8 includes a guide sleeve 81 fixedly installed inside the housing 1. The guide sleeve 81 is movably engaged with a rotating shaft 82 that penetrates the side wall of the housing 1. The rotating shaft 82 is movably sleeved with a support spring 83 located inside the guide sleeve 81. A stop plate 84 is fixedly connected to the outer side of the rotating shaft 82. A connecting plate 85 is fixedly installed to the outer side of the rotating shaft 82. A hexagonal head 86 corresponding to the hexagonal slot 61 is fixedly connected to the inner side of the connecting plate 85. Pulling the connecting plate 85 causes the rotating shaft 82 and the support spring 83 to move outward, and the support spring 83 is compressed. Then, the connecting plate 85 is rotated to the hexagonal slot 61 to release the connecting plate 85, so that the elastic force of the support spring 83 pushes the rotating shaft 82 and the connecting plate 85 inward. The hexagonal head 86 is engaged inside the hexagonal slot 61, limiting the rotation of the winding roller 6, realizing the limiting function, and ensuring the stable winding of the wire 7.

[0029] A fixing bolt 87 is movably installed on the outer side of the connecting plate 85. The fixing bolt 87 is threaded into the inside of the rotating shaft 82. The connecting plate 85 and the rotating shaft 82 are connected and fixed by the fixing bolt 87. The connecting plate 85 can be removed by removing the fixing bolt 87, and then the rotating shaft 82 can be removed from the inside of the guide sleeve 81 for easy maintenance.

[0030] Working principle: By rotating the handle on the outside of the winding roller 6, the wire 7 is wound onto the outside of the winding roller 6. During the winding process, the wire 7 passes between the ink-absorbing sponge 5 installed in the housing 1 and separated by the front partition 3, cleaning and absorbing excess ink and contaminants. By pulling the connecting plate 85 outward, the connecting plate 85 drives the rotating shaft 82 and the second support spring 83 to move outward. The second support spring 83 is located in the guide sleeve 81 and is squeezed by the inward and outward movement of the second support spring 83. Then, by rotating the connecting plate 85 to the hexagonal slot 61, the connecting plate 85 is released and the second support spring 83 pushes the second support spring 83 to move the rotating shaft 82 inward, which in turn drives the connecting plate 85 inward. This causes the hexagonal head 86 to be inserted into the hexagonal slot 61, restricting the rotation of the winding roller 6 and thus providing a limit to ensure the stable winding of the wire 7.

[0031] When the ink-absorbing sponge 5 needs to be replaced, the dial plate 410 is pushed forward, causing the dial plate 410 to move the slider 47 within the guide groove 44. Simultaneously, the slider 47 moves the insertion rod 46 forward and into the limiting hole 45 provided in the front cover plate 42. The insertion rod 46 is then removed from the limiting hole 45 in the rear cover plate 43 and the alignment plate 41 by its rear section. Subsequently, the front cover plate 42 and the rear cover plate 43 are flipped along the hinge joint with the housing 1 to open the housing 1, facilitating the replacement of the ink-absorbing sponge 5 and improving the convenience of maintenance. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
