Detailed Implementation

[0017] 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.

[0018] like Figures 1 to 3 The ink dispensing auxiliary structure shown includes an ink dispensing component 1 and a support rod 2. The ink dispensing component 1 has a first ink outlet 11 and a second ink outlet 12 that are connected to each other. The first ink outlet 11 is used to connect to the ink absorption device in the image forming equipment, while the second ink outlet 12 is housed within an ink bag. A connecting portion 13 is provided on the ink dispensing component 1 above the second ink outlet 12. This connecting portion 13 is integrally formed with the ink dispensing component 1, providing high structural strength and stability. A fixing hole 131 is provided on the connecting portion 13, and a fixing block 21 is provided at one end of the support rod 2. The fixing block 21 is integrally formed with the support rod 2, ensuring connection strength. When the support rod 2 is inserted to a certain depth, the fixing block 21 passes through the fixing hole 131, thereby fixing one end of the support rod 2 to the ink dispensing component 1.

[0019] In some possible embodiments, the support rod 2 is further provided with a first locking plane 22 and a second locking plane 23 spaced apart. The first locking plane 22 is located at the rear end of the fixing block 21, and the maximum outward extension dimension of the first locking plane 22 is greater than the minimum inner diameter of the fixing hole 131. In this way, after the support rod 2 is inserted, the first locking plane 22 can effectively prevent the support rod 2 from loosening and falling off in the axial direction, thus playing a locking role. The distance between the first locking plane 22 and the second locking plane 23 is approximately equal to the length dimension of the connecting part 13. After the fixing block 21 passes through the fixing hole 131, the connecting part 13 is restricted between the first locking plane 22 and the second locking plane 23, thereby constraining the degree of freedom of the support rod 2 in its axial direction.

[0020] In some possible embodiments, a first inclined guide surface 131a is formed within the fixing hole 131, the inner diameter of which gradually decreases from top to bottom, facilitating the insertion and guidance of the subsequent support rod 2. A second inclined guide surface 21a is formed at the front end of the fixing block 21, the outer diameter of which gradually decreases from top to bottom, matching the first inclined guide surface 131a of the fixing hole 131. This allows the fixing block 21 to be smoothly guided and elastically deformed during the insertion of the support rod 2, thereby allowing the fixing block 21 to pass through the fixing hole 131 and achieve a snap-fit ​​fixation.

[0021] In some possible embodiments, the rear end of the first inclined guide surface 131a is connected to the first positioning plane portion 131b, and the second locking plane 23 is formed with a second positioning plane portion 23a at one end near the first locking plane 22. The second positioning plane portion 23a passes through and is positioned on the first positioning plane portion 131b, which further enhances the stability and accuracy of the connection between the support rod 2 and the ink outlet component 1, avoids the support rod 2 from shaking in the radial direction, and improves the reliability of the overall structure.

[0022] Reference 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, and a stable installation is achieved through conventional fixing methods such as screws, clips, and adhesives, ensuring the positional accuracy and stability of the ink dispensing component 1 in the ink bag. The open end of the receiving bag is sealed to the ink dispensing component 1, and sealing processes such as heat sealing and adhesive bonding can be used to ensure that the ink does not leak, while preventing external impurities from entering the ink bag and affecting the ink quality. The support rod 2 is housed in the receiving bag, providing support for the receiving bag and ensuring that the ink dispensing component 1 can maintain a good working condition during the use of the ink bag, allowing the ink to be smoothly delivered from the second ink outlet 12 through the first ink outlet 11 to the ink absorption device of the image forming equipment.

[0023] The ink-dispensing auxiliary structure of this utility model is not only innovative in its structural design, but also performs excellently in practical applications. It effectively solves the problem that the support component is easy to detach from the ink-dispensing component in the prior art, and has broad market application prospects and high practical value.

[0024] 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.
