Description

Technical Field

[0001] The utility model relates to the field of printing supplies, in particular to an ink bottle cap which is easy to install and prevents ink leakage. Background Art

[0002] There are two main problems with the existing ink bottle cap. One is that the ink bottle cap mainly consists of three parts: an inner connecting cover, a silicone connector and an outer connecting cover. In the existing technology, the outer connecting cover and the inner connecting cover, as well as the inner connecting covers themselves, are fixedly connected by threaded connections. When the user opens the outer connecting cover, the inner connecting cover may also be opened, resulting in ink leakage. The second is that the silicone connector and the inner connecting cover are difficult to connect in the existing design, and the ink leakage prevention effect is not good enough. Therefore, there is a need for an ink bottle cap that is easier to connect between the silicone connector and the inner connecting cover, and will not drive the inner connecting cover to rotate when the outer connecting cover rotates, thereby facilitating use and reducing the occurrence of ink leakage. Utility Model Content

[0003] The main purpose of the utility model is to provide an easy-to-install anti-ink leakage ink bottle cap, which is easier to connect between a silicone connector and an inner connecting cover, and does not drive the inner connecting cover to rotate when the outer connecting cover rotates, thereby facilitating use and reducing the occurrence of ink leakage.

[0004] The utility model provides an easy-to-install ink bottle cap that prevents ink leakage, comprising an inner connecting cap, a silicone connecting piece and an outer connecting cap;

[0005] An inner connection hole is provided in the middle of the inner connection cover, an upper connection boss is provided on the top of the silicone connector, and a lower connection boss is provided on the bottom of the silicone connector. The upper connection boss cooperates with the lower connection boss to limit the silicone connector in the inner connection hole of the inner connection cover.

[0006] The inner connecting cover and the bottle body are fixedly connected by a threaded connection, and the inner connecting cover and the outer connecting cover are fixedly connected by a snap connection, so that the inner connecting cover cannot be driven to rotate by the outer connecting cover.

[0007] Preferably, a silicone connector through hole is provided in the middle of the silicone connector, a connector seal is provided on the top of the silicone connector through hole, and a connector gap for discharging ink is provided in the middle of the connector seal.

[0008] Preferably, an annular sealing protrusion is provided at the bottom of the side surface of the silicone connector.

[0009] Preferably, an inner connection cover connecting boss is provided on the bottom of the inner connection cover side surface, an annular inner connection cover connecting convex block is provided on the inner connection cover side surface above the inner connection cover connecting convex block, and an inner connection cover outer connection groove is formed between the inner connection cover connecting convex block and the inner connection cover connecting convex block;

[0010] An outer connection cover connection protrusion is provided on the inner side of the outer connection cover, and the outer connection cover connection protrusion cooperates with the outer connection groove of the inner connection cover, so that the outer connection cover is clamped and set on the inner connection cover.

[0011] Preferably, an inner connecting cover limiting protrusion is provided on the top of the inner connecting cover connecting boss, and a first inclined surface is provided on the top of the inner connecting cover limiting protrusion, and the first inclined surface is inclined from high to low in a clockwise direction. An outer connecting cover limiting protrusion adapted to the inner connecting cover limiting protrusion is provided on the bottom of the inner side surface of the outer connecting cover, and a second inclined surface adapted to the first inclined surface is provided on the bottom of the outer connecting cover limiting protrusion. Through the cooperation of the first inclined surface and the second inclined surface, the outer connecting cover can be detached from the inner connecting cover when the outer connecting cover is rotated.

[0012] Preferably, an inclined protrusion is provided on the inner bottom of the inner connection cover.

[0013] The beneficial effects of the easy-to-install ink bottle cap that prevents ink leakage of the utility model are:

[0014] By setting an upper connecting boss on the top of the silicone connector and a lower connecting boss on the bottom of the silicone connector, the upper connecting boss and the lower connecting boss can be matched to limit the silicone connector in the inner connecting hole of the inner connecting cover, thereby making the connection between the silicone connector and the inner connecting cover easier.

[0015] By arranging an annular sealing protrusion at the bottom of the side of the silicone connector, a better sealing effect can be achieved after the bottom of the silicone connector is inserted into the bottle body.

[0016] The inner connecting cap and the bottle body are fixedly connected by a threaded connection, and the inner connecting cap and the outer connecting cap are fixedly connected by a snap connection, so that the inner connecting cap cannot be driven to rotate by the outer connecting cap, thereby reducing the risk of ink leakage.
