Description

Technical Field

[0001] The utility model belongs to the technical field of inkjet printers and relates to a supporting base for an ink cartridge of an inkjet printer. Background Art

[0002] An inkjet printer is a software-controlled device that uses a non-contact method to mark products. The ink cartridge is a core component of the printer, storing the ink. The cartridge is supported by a base, and once connected to the base, it communicates with other structures (such as pins or quick connectors) through a connector.

[0003] Currently, there is a Chinese patent on the market with the announcement number CN210759813 U, which discloses a connection structure between an inkjet printer ink cartridge and a guide fixing seat. The structure can ensure a stable connection between the ink cartridge and the fixing seat. However, in practice, it is found that when the ink cartridge and the fixing seat are installed, the ink outlet and the air inlet on the ink cartridge are easily offset from the corresponding pin parts (i.e., other structures). This sometimes requires several operations and may even easily damage the pin parts, resulting in poor operation effect. Utility Model Content

[0004] The purpose of the utility model is to provide a support base for an inkjet printer ink cartridge, aiming to solve the problem of poor operating effect.

[0005] In order to solve the above technical problems, the utility model provides a support base for the inkjet printer cartridge, comprising a horizontal support transverse plate and a vertical support vertical plate, one end of the support transverse plate is connected to the bottom end of the support vertical plate, and limiting plates are vertically arranged on the top of both sides of the support transverse plate, and a limiting strip is horizontally arranged on the inner side of the limiting plate, and an arc-shaped guide portion is provided at one end of the limiting strip away from the support vertical plate, and the bottom of the guide portion is connected to the end of the limiting strip.

[0006] The utility model is further configured such that a long strip-shaped clearance opening is horizontally opened in the middle of the limit plate near one end of the supporting vertical plate, an elastic stabilizing strip is provided at one end of the clearance opening near the guide portion, the length of the elastic stabilizing strip is smaller than the length of the clearance opening, and a limiting protrusion is provided on the inner side of the elastic stabilizing strip.

[0007] The present invention is further configured such that the limiting protrusion is located at an end of the elastic stabilizing strip away from the guide portion.

[0008] The utility model is further configured such that a hinged column is provided on the inner side of the limit plate, the hinged column is higher than the limit bar, a self-locking piece is hingedly provided on the hinged column, the bottom of the self-locking piece is inclined, and the top of the inclined part is connected to the hinged column;

[0009] A movable opening for the self-locking part to move is provided at the connection between the limit bar and the guide portion. When the bottom of the self-locking part abuts against the lower side of the movable opening, the bottom of the self-locking part is lower than the bottom of the limit bar, and the side of the self-locking part close to the supporting vertical plate is vertical.

[0010] The present invention is further configured such that the thickness of the self-locking member is smaller than the thickness of the limiting strip and the guide portion, and the inner side of the self-locking member is movably fitted to the limiting plate.

[0011] The present invention is further configured such that a terminating plate is provided on the inner side of the limiting plate, and an elastic member which is continuously in a compressed state is provided between the lower side of the terminating plate and the upper side of the free end of the self-locking member.

[0012] The utility model is further configured such that an extension plate is provided on the inner side of the free end of the self-locking member, an anti-deformation plate is vertically provided on the top of the inner side of the extension plate, the elastic member is located on the outer side of the anti-deformation plate, and the movement trajectory of the termination plate and the anti-deformation plate is staggered.

[0013] The present invention is further configured such that an unlocking portion is obliquely provided on the top of the self-locking member, and the unlocking portion and the self-locking member are located on both sides of the hinge column.

[0014] The present invention is further configured such that an operating portion perpendicular to the unlocking portion is provided on the outer side of the unlocking portion, a movable opening for the operating portion to move is provided on the limiting plate, and the free end of the operating portion is located on the outer side of the limiting plate.

[0015] Compared with the prior art, the present invention provides a support base for inkjet printer cartridges, wherein a plate for limiting the position of a pin cartridge is provided on the side of the support vertical plate near the support horizontal plate. The support vertical plate also has an opening for the pin of the pin cartridge to pass through, and the lower opening is located at the lowest point of the support vertical plate, which can minimize the amount of ink residue in the pin cartridge. At the same time, the pin cartridge also has at least two protrusions on both sides, one of which is higher and contacts the lower side of the limiting strip, allowing the pin cartridge to be limited in the vertical direction. At the same time, the bottom of the pin cartridge movably contacts the top of the support horizontal plate, and the two sides contact the inner side of the limiting strip, thereby ensuring the height of the pin cartridge and the position of the pin, and being able to be stably connected to other structures. This not only makes operation more convenient, but also prevents collisions between structures, thus providing protection for each structure. Moreover, the guide portion at the end of the limit strip is in an upward arc shape. Therefore, even if the height of the protrusion on the side of the pin cartridge does not reach the appropriate height, it can be driven downward after acting on the lower side of the guide portion and eventually reach the appropriate height, resulting in better operating effect.

[0021] The following is a detailed description of the support base for inkjet printer cartridges proposed by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention. Identical or similar reference numerals in the accompanying drawings represent identical or similar components.

[0022] A support base for inkjet printer cartridges, such as Figures 1 to 4 As shown, it includes a horizontal supporting transverse plate 1 and a vertical supporting vertical plate 2, one end of the supporting transverse plate 1 is connected to the bottom end of the supporting vertical plate 2, and limiting plates 3 are vertically arranged on the top of both sides of the supporting transverse plate 1, and a limiting strip 4 is horizontally arranged on the inner side of the limiting plate 3. An arc-shaped guide portion 5 is provided at one end of the limiting strip 4 away from the supporting vertical plate 2, and the bottom of the guide portion 5 is connected to the end of the limiting strip 4.

[0023] The limiting plate 3 has a long horizontal opening 6 in the middle of one end near the supporting vertical plate 2. The opening 6 is provided with an elastic stabilizing strip 7 at the end near the guide portion 5. The length of the elastic stabilizing strip 7 is shorter than that of the opening 6. A limiting protrusion 8 is provided on the inner side of the elastic stabilizing strip 7. The limiting protrusion 8 is located at the end of the elastic stabilizing strip 7 away from the guide portion 5.

[0024] A hinged column 9 is provided on the inner side of the limiting plate 3. The hinged column 9 is higher than the limiting bar 4. A self-locking member 10 is hingedly provided on the hinged column 9. The bottom of the self-locking member 10 is inclined, and the top of the inclined part is connected to the hinged column 9.

[0025] The connection between the limiting strip 4 and the guide portion 5 defines a movable opening 11 for the self-locking member 10 to move. When the bottom of the self-locking member 10 contacts the lower side of the movable opening 11, the bottom of the self-locking member 10 is lower than the bottom of the limiting strip 4, and the side of the self-locking member 10 close to the support riser 2 is vertical. The thickness of the self-locking member 10 is less than that of the limiting strip 4 and the guide portion 5, and the inner side of the self-locking member 10 is movably attached to the limiting plate 3.

[0026] A stop plate 12 is provided inside the limit plate 3. A continuously compressed elastic member 13 is provided between the lower side of the stop plate 12 and the upper side of the free end of the self-locking member 10. An extension plate 14 is provided inside the free end of the self-locking member 10. A deformation prevention plate 15 is vertically installed on the top of the inner side of the extension plate 14. The elastic member 13 is located outside the deformation prevention plate 15, and the movement trajectories of the stop plate 12 and the deformation prevention plate 15 are offset.

[0027] An unlocking portion 16 is provided at an angle on the top of the self-locking member 10. The unlocking portion 16 and the self-locking member 10 are located on both sides of the hinge column 9. An operating portion 17 is provided on the outside of the unlocking portion 16 and is perpendicular to the unlocking portion 16. A movable opening 18 for the operating portion 17 to move is provided on the limiting plate 3. The free end of the operating portion 17 is located on the outside of the limiting plate 3.

[0028] The utility model provides a support base for inkjet printer ink cartridges, wherein a plate for limiting the position of a pin cartridge is provided on the side of the support vertical plate 2 near the support horizontal plate 1. The support vertical plate 2 also has an opening for the pin of the pin cartridge to pass through, and the lower opening is located at the lowest point of the support vertical plate 2, which can minimize the amount of ink residual in the pin cartridge. The pin cartridge also has at least two protrusions on both sides, one of which is higher and contacts the lower side of the limiting strip 4, thereby limiting the pin cartridge in the vertical direction. The bottom of the pin cartridge flexibly contacts the top of the support horizontal plate 1, and both sides contact the inner side of the limiting strip 4. This ensures the height of the pin cartridge and the position of the pin, allowing it to be stably connected to other structures, not only making operation more convenient, but also preventing collisions between structures, thus providing protection for all structures. Moreover, the guide portion 5 at the end of the limit strip 4 is in an upward arc shape. Therefore, even if the height of the protrusion on the side of the pin cartridge does not reach the appropriate height, it can be driven downward after acting on the lower side of the guide portion 5 and eventually reach the appropriate height, resulting in a better operating effect.

[0029] In the process of installing the pin ink cartridge on the support base, first, the smaller protrusion in the front passes the lower side of the self-locking part 10 (or may not act on it) and drives the self-locking part 10 to rotate upward. After the small protrusion passes the self-locking part 10, the large protrusion acts on the lower side of the self-locking part 10 and drives the self-locking part 10 to rotate upward. When the protrusion just passes the self-locking part 10, the ink cartridge is also installed in the appropriate position. At this time, it rotates downward under the action of the elastic force of the elastic part 13 and the gravity of the self-locking part 10, and the vertical side of the self-locking part 10 is tilted. It abuts against the outside of the larger protrusion, which can prevent the ink cartridge from moving outward and ensure the position stability of the ink cartridge; not only that, during the movement of the small protrusion, it will first act on the inner side of the limiting protrusion 8 and drive the elastic stabilizing strip 7 to move outward. When the small protrusion just passes the limiting protrusion 8, the pin ink cartridge is installed, and the elastic stabilizing strip 7 moves toward the ink cartridge under the action of elastic force, so that the limiting protrusion 8 abuts against the outside of the small protrusion, so that the limiting protrusion 8 further limits the pin ink cartridge.

[0030] To remove the ink cartridge, one simply presses down on the operating portion 17, which drives the unlocking portion 16 downward, causing the self-locking member 10 to rotate upward. The inner wall of the movable opening 18 has an elastic protrusion that exerts a large force on the operating portion 17, temporarily securing the operating portion 17 in place after it passes through the elastic protrusion. The worker then bends the elastic stabilizing bar 7 outward to move the ink cartridge directly outward. Alternatively, the ink cartridge can be moved directly outward, with the small protrusion acting on the limiting protrusion 8, directly driving the elastic stabilizing bar 7 to move. During actual operation, the ink cartridge also has a groove for the worker to apply force.

[0031] After the ink cartridge is separated from the support base, the operating portion 17 is simply rotated upward to separate it from the elastic protrusion. The self-locking member 10 is then rotated downward until its underside contacts the underside of the movable opening 11, ready for the next use. During use, the elastic member 13 is restrained on both sides by the limiting plate 3 and the anti-deformation plate 15, effectively preventing elastic deformation and ensuring its service life.

[0032] The above description is only a description of the preferred embodiment of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
