Description

Technical Field

[0001] The utility model particularly relates to an ink refiller with high compatibility. Background Art

[0002] The existing ink refiller includes a base, a receiving cavity for accommodating an ink cartridge is formed on the base, an ink inlet hole is opened on the outer side wall of the base, an ink outlet hole is arranged in the receiving cavity, a guiding hole communicating the ink outlet hole and the ink inlet hole is opened on the base, and a fastening handle is arranged on the base. When ink refilling is needed, the ink cartridge is pressed tightly in the receiving cavity by using the fastening handle, and ink is injected into the ink inlet hole by a syringe. The ink is output through the guiding hole and the ink outlet hole, and the filling ink is adsorbed by a sponge after being input from the ink outlet of the ink cartridge, and then the ink refilling is completed. The implementation principle of the above-mentioned fastening handle is as follows: the fastening handle includes a screw rod and a handgrip part. By rotating the handgrip part, the screw rod rotates. During the process of the screw rod being in threaded cooperation with the base, one end of the screw rod can extend into the receiving cavity to press the ink cartridge tightly, and then the subsequent ink refilling operation is carried out. However, this cooperation method has the following problems:

[0003] Due to the high compatibility of the ink refiller, it can be applied to ink refilling of various different types of ink cartridges. That is to say, the fastening handle needs to be turned multiple times. However, after the screw rod is in threaded cooperation with the base multiple times, the thread between the screw rod and the base is prone to wear, reducing the connection strength between the screw rod and the base. Then, during the ink refilling process of the ink refiller, the ink cartridge may shift in the receiving cavity, ultimately affecting the ink refilling effect. Summary of the Utility Model

[0022] An ink refiller with high compatibility includes a base 1. The base 1 is recessed inwardly to form a receiving cavity 3 for receiving an ink cartridge 2. An installation seat 4 is provided on the base 1. An installation groove 5 is provided in the installation seat 4. Elastic structures are symmetrically provided in the installation groove 5. A swing arm 6 is hinged on each elastic structure. The two swing arms 6 are commonly connected to an abutting rod. The swing arm 6 drives the abutting rod to move downward under the action of the elastic structure to tightly abut the ink cartridge 2.

[0023] Further, the elastic structure includes a fixed frame 71 provided in the installation groove 5 and a movable block 72 slidably provided on the fixed frame 71. A spring 73 is connected between the movable block 72 and the fixed frame 71. The swing arm 6 is hinged on the movable block 72.

[0024] Further, the abutting rod includes a connecting plate 81 and a column 82 provided at the lower end of the connecting plate 81. A pull rod 83 is provided at the upper end of the connecting plate 81. The two ends of the connecting plate 81 are respectively hinged on the swing arm 6.

[0025] Further, a rubber sleeve 9 is provided at one end of the column 82 close to the ink cartridge 2.

[0026] Further, a handgrip portion 10 is provided on the pull rod 83.

[0027] Further, a through hole 11 through which the abutting rod can pass is provided on the base 1. The through hole 11 communicates with the receiving cavity 3.

[0028] The working principle of the present utility model is:

[0029] Such as Figure 1As shown in the figure, before the ink filling operation, pull the upper end of the abutting rod to move it upward. Since swing arms 6 are respectively hinged on both sides of the abutting rod, and an elastic structure is hinged on each swing arm 6, the abutting rod will drive the swing arms 6 to swing during the upward movement, and the swing arms 6 will pull the elastic structure to deform the elastic structure. When the abutting rod moves out of the receiving cavity 3, the ink cartridge 2 can be placed into the receiving cavity 3. Then release the abutting rod. Since the elastic structure will recover the amount of deformation, the elastic structure will drive the swing arms 6 to drive the abutting rod to move downward, and finally the abutting rod will abut tightly against the ink cartridge 2, thereby limiting the ink cartridge 2 in the receiving cavity 3. Then the ink filling operation can be performed at this time. As Figure 1 shown, a syringe 1-1 can be selected to inject into the ink filling hole to achieve the ink filling operation of the ink cartridge 2. How the ink of the syringe 1-1 enters the ink outlet of the ink cartridge 2 through the ink filling hole, the guide hole, and the ink outlet hole has been recorded in a prior patent, and this part is not the main design concept of this application, so the working principle will not be described in detail herein.

[0030] As Embodiment 1, the implementation cooperation mode of the elastic structure can be: fixing frames 71 are symmetrically arranged in the installation groove 5, movable blocks 72 are movably arranged on each fixing frame 71, the swing arms 6 are hinged on the movable blocks 72, and springs 73 are connected between the movable blocks 72 and the fixing frames 71. That is to say, when the abutting rod moves upward, it will drive the swing arms 6 to pull the two movable blocks 72 to move closer to each other. At this time, the movable blocks 72 will pull the springs 73 to make the springs 73 in a stretched state. When the abutting rod is released, the springs 73 will recover the deformation to drive the movable blocks 72 to reset, and then drive the abutting rod to move downward through the swing arms 6, so as to abut the ink cartridge 2 tightly in the receiving cavity 3.

[0031] On the basis of the above technical solution, regarding the setting of the abutting rod, the structure cooperation mode such as a connecting plate 81 and a column 82 can be selected. Specifically, both sides of the connecting plate 81 are respectively hinged on the swing arms 6, the column 82 is arranged at the lower end of the connecting plate 81, and a pull rod 83 is arranged at the upper end of the connecting plate 81. For the convenience of the user's operation, a handgrip 10 can also be arranged on the pull rod 83.

[0032] On the basis of the above technical solution, in order to prevent the ink cartridge 2 from being deformed due to excessive force when the column 82 abuts tightly against the ink cartridge 2, a rubber sleeve 9 is arranged on the column 82. The setting of the rubber sleeve 9 can buffer the impact force of the column 82 on the ink cartridge 2, thereby effectively protecting the ink cartridge 2.

[0033] In order to overcome the problem of ink cartridge displacement caused by the screw thread fitting in the prior art, the present application provides an installation seat on the base, and an installation groove is arranged in the installation seat. An elastic structure arranged in the installation groove drives the abutting rod to move downward so as to tightly abut the ink cartridge, replacing the existing thread fitting method and effectively avoiding the phenomenon of ink cartridge displacement.

[0034] Although the present utility model has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art from this disclosure that various changes or modifications can be made to the present utility model without departing from the principle and spirit scope of the present utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present utility model, and the scope of protection is defined by the content of the claims.
