Description

[Technical field]

[0001] The utility model relates to the technical field of ink barrels, in particular to a barrel cover connecting structure of an ink barrel. [Background technology]

[0002] After the ink is produced, it will be filled into ink barrels for storage, and then packaged, transported and sold. At present, there are two types of ink packaging on the market, one is a large barrel structure, and the other is a small barrel structure. After the lid of the ink barrel with a small barrel structure is opened, the threaded structure inside the barrel cover is easily stained with ink. After the ink solidifies, the barrel cover is difficult to open again and difficult to reconnect with the barrel body. Therefore, users can only clean the ink on the threaded structure before reassembling the barrel cover and barrel body, which is inconvenient to use. [Contents of the utility model]

[0003] The purpose of the utility model is to overcome the above problems. We provide a barrel cover connection structure for an ink barrel. The connection structure solves the problem that the inner thread structure of the barrel cover is contaminated with ink and is difficult to assemble.

[0004] To achieve the above-mentioned purpose, we provide a barrel cover connection structure for an ink barrel, which includes a barrel body, a barrel cover and a sealing ring. The bottom end of the barrel cover has an annular mounting groove, and the opening at the upper end of the barrel cover is inserted into the mounting groove. The outer peripheral wall of the barrel cover is provided with a first external thread structure, and the outer peripheral wall of the barrel body is provided with a second thread structure. The inner peripheral wall of the sealing ring is provided with an internal thread structure, and the sealing ring is connected to the first external thread structure and the second external thread structure through the internal thread structure to tightly connect the barrel cover and the barrel body together.

[0005] In one or more embodiments, the depth of the mounting groove is 5MM-15MM.

[0006] In one or more embodiments, an annular wall is provided at the bottom end of the barrel cover, the mounting groove is formed between the annular wall and the side wall of the barrel cover, and the annular wall and the barrel cover are an integral injection-molded structure.

[0007] In one or more embodiments, a recess is provided on the upper end surface of the barrel cover, the size of the recess is consistent with the size of the bottom end of the barrel body, and the bottom end of the barrel body can be embedded in the recess.

[0008] In one or more embodiments, a limiting edge is disposed on the outer peripheral wall of the barrel cover, and the limiting edge is located above the first external thread structure, and the limiting edge can abut against the sealing ring.

[0009] In one or more embodiments, anti-slip ribs are provided on the outer peripheral wall of the sealing ring.

[0010] Compared with the background technology, the utility model has the following technical effects: an external thread structure is arranged on the outer peripheral wall of the barrel cover and the barrel body, and the two are assembled together after the external thread structures of the two are connected by a sealing ring, thereby solving the problem of ink contamination on the inner side of the barrel cover and ensuring that the user can easily open and close the barrel cover every time.

Brief Description of the Drawings

[0011] Figure 1 It is a schematic structural diagram of the connection between the barrel cover, barrel body and sealing ring in an embodiment of the utility model. [Specific implementation method]

[0012] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0013] Please see Figure 1 The present application provides a barrel cover connection structure for an ink barrel, which includes a barrel body 1, a barrel cover 2 and a sealing ring 3. The bottom end of the barrel cover 2 has an annular mounting groove, and the opening at the upper end of the barrel cover 2 is inserted into the mounting groove to achieve a sealed connection between the barrel cover and the barrel body. The outer peripheral wall of the barrel cover 2 is provided with a first external thread structure 4, and the outer peripheral wall of the barrel body 1 is provided with a second thread structure 5. The inner peripheral wall of the sealing ring 3 is provided with an internal thread structure 6. The sealing ring is connected to the first external thread structure and the second external thread structure through the internal thread structure to tightly connect the barrel cover 2 and the barrel body 1 together. The user can open the barrel cover by rotating the sealing ring to release the connection with the first external thread structure or the second external thread structure. When the barrel cover is connected to the barrel body, the sealing ring can be reconnected to the first external thread structure and the second external thread structure.

[0014] The depth of the installation groove is 5MM-15MM, preferably 10MM, to ensure that the installation groove has a certain depth for the opening position of the barrel body to be embedded and connected, thereby ensuring the tightness of the connection between the barrel cover and the barrel body.

[0015] An annular wall 7 is disposed at the bottom end of the barrel cover 2, and the mounting groove is formed between the annular wall and the side wall 21 of the barrel cover 2. The annular wall and the barrel cover are an integral injection-molded structure.

[0016] The upper end surface of the barrel cover 2 is provided with a recess 8, the size of which is consistent with the size of the bottom end of the barrel body 1. The bottom end of the barrel body can be embedded in the recess. When packaging and transporting, the ink barrels can be stacked up and down. The bottom of the upper barrel body is embedded in the barrel cover of the lower barrel body, which can improve the stability of the ink barrels after stacking.

[0017] The outer wall of the barrel cover 2 is provided with a limiting edge 9, which is located above the first external thread structure 4. The limiting edge can abut against the sealing ring 3. Every time the user needs to open the barrel cover, the user twists the sealing ring downward to disengage it from the first external thread structure, and then the user opens the barrel cover; after the user closes the barrel cover, the sealing ring is twisted upward to connect it with the first external thread structure. The limiting edge can remind the user that when the sealing ring is twisted until it abuts against the limiting edge, it means that the sealing ring is positioned in place, which can ensure that the barrel cover and the barrel body are tightly assembled together.

[0018] The outer wall of the sealing ring 3 is provided with anti-skid ribs 31 to increase the friction of the outer wall of the sealing ring, making it easier for users to operate the sealing ring.

[0019] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
