Detailed Implementation

[0018] 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.

[0019] like Figures 1 to 3 The illustrated ink dispensing auxiliary structure is applied to an ink bag with a receiving pouch, comprising an ink dispensing component 1 and a support component 2. The ink dispensing component 1 is sealed to the open end of the receiving pouch (not shown). An ink dispensing channel 14 is provided on the ink dispensing component 1, one end of which is connected to an ink absorption device in an image forming apparatus. Ink from the receiving pouch flows from the ink dispensing channel 11 to the ink absorption device. The support component 2 is disposed inside the receiving pouch. A rotating shaft 22 is provided at one end of the support component 2, and a connecting portion 13 is provided at the end of the ink dispensing component 1 located inside the receiving pouch. A rotating hole 132 is provided on the connecting portion 13. The rotating shaft 22 engages with the rotating hole 132 to allow the ink dispensing component 1 and the support component 2 to be rotatably connected. This allows the support component 2 to rotate relative to the ink dispensing component 1 when the ink dispensing auxiliary structure is affected by external forces, thereby effectively dispersing the stress on the support component 2, preventing bending or breakage of the support component 2, and improving the reliability of the ink bag structure.

[0020] In some possible embodiments, the rotating hole 132 is circular, and the rotating shaft 22 is disposed on opposite sides of the support member 2. The cross-section of the rotating shaft 22 is waist-shaped, and its outer periphery forms two positioning planes 22a and two rotating arc surfaces 22b, which are symmetrically arranged. There are two connecting parts 13, which are disposed opposite to one end of the ink outlet member 1. The inner sides of the two connecting parts 13 are provided with guide mounting grooves 133. The rotating shaft 22 is inserted into the rotating hole 132 through the guide mounting groove 133. The guide mounting groove 133 facilitates the installation and positioning of the rotating shaft 22, improving assembly efficiency. The waist-shaped design of the rotating shaft 22 ensures that the long axis of the rotating shaft 22 is in the same direction or even coincides with the axis of the guide mounting groove 133, so that it can be dislodged from the rotating hole 132, ensuring a reliable connection between the support member 2 and the ink outlet member 1. The design of the positioning plane 22a and the rotating arc surface 22b enables the support member 2 to rotate within the rotating hole 132 after it is connected to the ink outlet member 1.

[0021] In some possible embodiments, the axial direction of the guide mounting groove 133 is perpendicular to the axial direction of the ink outlet channel 14, and the length axis of the support member 2 is in the same direction as the axis of the ink outlet channel 14 in the working state. The support member 2 is inside and constrained by the receiving bag, so it cannot be subjected to external force and rotated to a position where its axis is in the same direction / coincides with the direction of the guide mounting groove 133. Therefore, it is ensured that the support member 2 cannot be separated from the ink outlet member 1 after the product is assembled, further ensuring the reliability of the product structure.

[0022] In some possible embodiments, a first guide slope 133a is provided at the bottom of the upper end of the guide mounting groove 133, and second guide slopes 133b are provided on both sides of the upper end of the guide mounting groove 133. The minimum distance between the two second guide slopes 133b is approximately equal to the width of the rotating shaft 22. The provision of the first guide slope 133a and the second guide slope 133b further improves the ease and accuracy of installation of the rotating shaft 22 in the guide mounting groove 133, ensuring that the rotating shaft 22 can be smoothly inserted into the rotating hole 132.

[0023] In some possible embodiments, reinforcing ribs 134 are formed on the opposite outer sides of the connecting portion 13. The reinforcing ribs 134 enhance the structural strength of the connecting portion 13, improve the stability of the connection between the ink outlet 1 and the support 2, and effectively prevent the connecting portion 13 from deforming or being damaged.

[0024] In some possible embodiments, one end of the support member 2 with the pivot 22 is rounded. The rounded design improves the smoothness of the support member 2 during assembly and prevents sharp edges from scratching the receiving bag or other components.

[0025] In some possible embodiments, the connecting part 13 is integrally formed with the ink outlet component 1, and the rotating shaft 22 is integrally formed with the support component 2. The integral forming design improves the connection strength and integrity between the components, ensuring the reliability and stability of the ink outlet auxiliary structure during long-term use.

[0026] like Figure 4 As shown, this utility model also provides an ink bag, which includes the aforementioned ink dispensing auxiliary structure, a fixing base 3, and a receiving bag (not shown). The ink dispensing component 1 is fixedly installed in the fixing base 3 by conventional methods such as screws, clips, and adhesives. The open end of the receiving bag is sealed to the ink dispensing component 1, specifically by heat sealing, adhesive bonding, or other sealing processes, to ensure that the ink does not leak and to prevent external impurities from entering the ink bag and affecting the ink quality. The support component 2 is housed in the receiving bag and one end is rotatably connected to the ink dispensing component 1. The support component 2 provides support for the receiving bag, ensuring that the ink dispensing component 1 maintains a good working condition during the use of the ink bag, allowing the ink to be smoothly delivered from the ink dispensing channel 14 to the ink absorption device of the image forming equipment. The rotatable design between the support component 2 and the ink dispensing component 1 prevents the support component 2 from bending or breaking due to external forces, thus improving the reliability of the ink bag structure.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
