[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely in the following by combining with the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled person in the art without creative labor belong to the scope of protection of the utility model.

[0019] As Figs. 1-3The chip fixing structure shown comprises a chip mounting portion 2 arranged at the lower end of the ink cartridge 1. The chip mounting portion 2 has an insertion opening for the chip 3 to be inserted from front to back. The chip mounting portion 2 is provided with a clamping groove 22 on each of the left and right sides, and the chip 3 is clamped between the two clamping grooves 22. The upper end of the chip mounting portion 2 is further connected with an elastic cantilever 4, which comprises a hand-holding portion 41 extending upward and a locking block 42 extending downward, and the locking block 42 can limit the chip 3 from being pulled out of the insertion opening.

[0020] When the chip 3 is installed, the user presses the hand-holding portion 41 to drive the locking block 42 to give way from the opening of the insertion opening, and then aligns the rear end of the chip 3 with the insertion opening, and then pushes the chip 3 backward along the direction of the insertion opening. During the pushing process, the two sides of the chip 3 will gradually enter the bottom of the chip mounting portion 2 along the clamping grooves 22. When the chip 3 is completely inserted into place, the user releases the hand-holding portion 41, and the elastic cantilever 4 restores to the original position under the elastic force of itself, and the locking block 42 is clamped at the front end of the chip 3, thereby realizing the fixation of the chip 3.

[0021] When the chip 3 is removed, the user only needs to press the hand-holding portion 41 with the fingers to make the locking block 42 give way from the opening of the insertion opening, and then the user can easily take out the chip 3 from the insertion opening from back to front.

[0022] The chip fixing structure of the utility model has the advantages that through reasonable structural design, the chip is convenient to disassemble and effectively protected, the recycling of the ink cartridge chip is improved, and the chip fixing structure has good market application prospect.

[0023] In some possible embodiments, the clamping groove 22 is composed of a horizontal limiting portion 221 and two vertically arranged limiting portions 222. The horizontal limiting portions 221 of the two clamping grooves 22 cooperate to constrain the freedom of the chip 3 in the left-right direction, and the two vertically arranged limiting portions 223 cooperate to constrain the freedom of the chip 3 in the vertical direction. The vertically arranged limiting portions 223 of the two clamping grooves 22 are arranged on the two sides to cooperate to limit the chip 3, so as to ensure the levelness of the chip 3 on the ink cartridge 1. The bottom of the chip mounting portion 2 cooperates with the locking block 42 to constrain the freedom of the chip 3 in the front-back direction, so as to fix the chip 3 on the chip mounting portion 2. The front end of the vertically arranged limiting portion 222 is provided with an inclined guide surface 223. The design of the inclined guide surface 223 helps the chip 3 to smoothly enter the clamping groove 22 during insertion, and reduces the insertion resistance.

[0024] In some possible embodiments, the locking block 42 is two, and the two locking blocks 42 are respectively close to the two clamping grooves 22, so that the chip 3 is fixed on the chip mounting portion 2.

[0025] In some possible embodiments, the length of the lock block 42 extending downward is a, and the thickness of the chip 3 is b, then 1 / 2b≤a≤2 / 3b. Such a size design can ensure the effective restriction of the chip 3 by the lock block 42, and at the same time, when disassembling, the user only needs to press the hand-held part 41 and drive the lock block 42 to move a small distance, so as to loosen the constraint of the chip 3, which is convenient for the user to take out the chip 3.

[0026] In some possible embodiments, the rear end of the chip mounting part 2 is provided with a taking groove 23 for facilitating taking out the chip 3. The provision of the taking groove 23 facilitates the fingers or tools of the user to extend into the rear end of the chip 3 to push the chip 3 to slide out of the chip mounting part 2 from the card slot 22.

[0027] In some possible embodiments, the elastic suspension arm 4 is provided with a giving hole 43 for the protrusion at the back of the chip 3. The design of the giving hole 43 avoids the interference between the elastic suspension arm 4 and the protrusion at the back of the chip 3, and ensures that the chip 3 can be smoothly mounted and disassembled.

[0028] In some possible embodiments, the chip mounting part 2 is integrally formed with the ink cartridge 1. Such an integral design not only improves the stability of the structure, but also reduces the production cost and simplifies the manufacturing process.

[0029] The utility model also provides a kind of ink cartridge, referring to Figs. 1-3 As shown in the figure, the ink cartridge includes the chip fixing structure of the above embodiment.

[0030] The above is only the specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any change or replacement in the technical range disclosed by the utility model should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be limited to the protection scope of the claims.
