[0002] The ink pad is an important supporting device for cleaning and moisturizing the print head of an inkjet printer. It includes a packaging mesh, a filtering and moisturizing gasket, a plastic and rubber integrated base, a spring and a plastic bottom box. The base is provided with a closed-loop rubber seal around the peripheral edge of the rectangular open end. After being produced in the factory, the ink pad is simply boxed and transported to the use site of the inkjet printer for installation and use. The open end of the base lacks other covers. Before packaging, transportation and finally being installed on the printer, foreign objects may fall into the open end of the base, or the rubber seal may be damaged locally by collision. The damage of the rubber seal will affect the sealing, cleaning and moisturizing effects of the ink pad on the print head during use. If the sealing, cleaning and moisturizing are not in place, the print head cannot work properly. Content of the Utility Model

[0003] To solve the technical problem that the ink pad used on the existing printer lacks protection to cover the open end of the base and cannot protect the rubber seal around the top edge of the base before the ink pad is installed on the printer, the utility model provides an ink pad with a protective cover. By installing a detachable protective cover at the open end of the base on the top of the ink pad, the open end of the base is covered and protected to prevent foreign objects from falling into the open end and protect the sealing rubber around the top edge of the base from being damaged.

[0004] The technical solution adopted by the utility model to solve the technical problem: an ink pad with a protective cover, the upper part of the ink pad is a base, the top end of the base is open and an elastic seal is arranged around the open end. The feature is that a protective cover is arranged on the base to cover the open end of the base. The protective cover includes a top plate covering the open end and a positioning structure arranged at its edge. The protective cover is detachably connected to the base through the positioning structure. The utility model covers the open end of the base by installing a detachable protective cover on the base, avoiding foreign objects from falling into the open end and protecting the elastic seal arranged around the open end of the base. After removing the protective cover, the ink pad can be installed on the inkjet printer for normal use.

[0005] As a further improvement and supplement to the above technical solution, the present utility model adopts the following technical measures: The positioning structure is a plurality of elastic buckles provided on the side surface of the top plate. The protective cover is buckled on the base along the direction perpendicular to the plane of the base and locks the side surface of the base through the elastic buckles; or the protective cover slides along the direction parallel to the plane of the base from the side surface of the base and is clamped with the base. The positioning structure is clamping plates opposite to each other on both sides of the top plate, and two open slots matching the two clamping plates are provided on the side surface of the base. The connection and positioning between the protective cover and the base can be that the protective cover is elastically buckled with the base along the direction perpendicular to the plane of the base. At this time, the positioning structure is a number of elastic buckles, and the protective cover is connected to the base by clamping the side surface of the base tightly through the elastic buckles; or the protective cover can also be clamped with the base along the direction parallel to the plane of the base from the side surface of the base. At this time, the positioning structure is clamping plates opposite to each other on both sides of the top plate, and the clamping plates are matched with the open slots paired with the side surface of the base to connect the protective cover with the base.

[0006] Preferably, the elastic buckles are a plurality of independent elastic arms extending from the opposite side edges on the top plate. The elastic arms bend and extend outward and downward, and the lower ends of the elastic arms form elastic locking portions tending inward. The elastic arms on the same side of the top plate are parallel to each other. Independent elastic arms are provided on the opposite side edges on both sides of the top plate. Each elastic arm forms an elastic locking portion tending inward through bending and extension. When the protective cover and the base are connected, each elastic arm clamps the side surface of the base through the elastic locking portion at the lower end.

[0007] Preferably, there are four elastic arms, and the four elastic arms are symmetrically arranged in two groups on the opposite side edges of the top plate. The four elastic arms are symmetrically arranged in two groups on the opposite side edges of the top plate, with two elastic arms on each side. The two groups of four elastic arms on both sides of the top plate act together to clamp the two side surfaces of the base tightly so that the protective cover is buckled on the base.

[0008] Preferably, a plurality of vertically downward positioning arms extend from the opposite side edges on the top plate, and the edges of the top plate where the positioning arms are located are adjacent to the edges of the top plate where the elastic arms are located. Generally, the base is rectangular with four sides. The elastic arms clamp the two sides of the base to limit the movement of the protective cover along the clamping direction of the elastic locking portion. The positioning arms cooperate with the elastic arms to further limit the protective cover buckled on the base to prevent the protective cover from moving along the direction perpendicular to the clamping direction, so that the protective cover will not translate and come out after being buckled in place.

[0009] Preferably, at least two opposite side walls are provided on the edge of the top plate. The side walls extend along the edge of the top plate and vertically downward. The elastic buckles are protrusions on the inner surface of the side walls, and a concave matching the protrusion is provided on the side surface of the base. When the protective cover is buckled on the base, the protrusions are buckled into the concave. The top plate uses the protrusions on the inner surfaces of at least two opposite side walls extending from the edge as elastic buckles to be buckled into the matching concave on the side surface of the base to realize the buckling connection between the protective cover and the base.

[0010] Preferably, the top plate is provided with four side walls around its periphery. The four side walls face each other in pairs and are connected to form a closed perimeter that encircles. Raised portions are provided on the inner surfaces of the four side walls, and inward concavities that match the raised portions are provided around the side surface of the base. When the protective cover and the base are fastened in place, the closed perimeter tightly sleeves the upper part of the base. By providing four side walls around the periphery of the top plate to form a closed perimeter that encircles, raised portions are provided on the inner surface of each side wall, and corresponding inward concavities are also provided on the side surface of the base. When the protective cover and the base are fastened in place, the raised portions are snapped into the corresponding inward concavities, causing the closed perimeter to tightly sleeve the upper part of the base.

[0011] Preferably, the bottom ends of the clamping plates on both sides of the top plate bend and extend inward towards the opposite clamping plate to form two opposing sliding rails. When the protective cover and the base are clamped, the sliding rails move into the slots from the openings of the matching open slot grooves. The bottom ends of the clamping plates on both sides of the top plate extend to form sliding rails that bend inward, and match the two open slot grooves on both sides of the base. The sliding rails move into the slots from the open ends of the slots. Using the cooperation of the sliding rails and the slots, the sliding of the protective cover is guided and limited.

[0012] Preferably, a locking structure is provided between the front end of the sliding rail and the inner end of the open slot groove to lock the protective cover in place when it slides into position. Through the locking structure, the protective cover is locked in position after sliding relative to the base, preventing the protective cover from loosening and causing the opening of the base to be exposed.

[0013] Preferably, the locking structure includes a partition rib provided in the open slot groove and a notch provided at the front end of the sliding rail. The partition rib divides the open slot groove into an outer slot section that communicates with the opening and an inner slot section that is closed at the inner end of the slot. The notch divides the sliding rail into a front locking head section and a rear free section. After the protective cover slides into position relative to the base, the locking head section is snapped into the inner slot section, the partition rib is inserted into the notch, and the free section is snapped into the outer slot section. By using the partition rib and the opened notch to respectively partition the open slot groove and the sliding rail, after the protective cover slides into position relative to the base, the two sections divided by the slot and the two sections divided by the sliding rail match each other, and at the same time, the partition rib and the notch match, locking the position of the protective cover. When it is necessary to remove the protective cover, the protective cover is translated outward, causing the locking head section to flip over the adjacent blocking partition rib to disengage from the inner slot section. When the locking head section is completely moved to the outer slot section, the protective cover can slide freely along the outer slot section and be removed from the base.

[0014] The beneficial technical effects of the present utility model: By installing a detachable protective cover on the base to temporarily protect the opening of the base, preventing foreign objects from falling into the opening and protecting the elastic seal around the opening of the base from being damaged before the final installation on the machine. The detachable connection between the protective cover and the base can be achieved by elastically snapping the protective cover onto the base from top to bottom, or by laterally sliding and clamping the protective cover onto the base from the side of the base. Whether it is the vertical installation of the snap connection or the horizontal installation of the clamping connection, the protective cover is not easily loosened or detached after being installed in place.

[0025] The following further describes the present utility model in conjunction with the accompanying drawings and detailed implementation manners.

[0026] Embodiment 1 is as shown in Figures 1 to 3As shown, an ink pad with a protective cover is provided. The upper part of the ink pad 1 is a base 3. The top of the base 3 is open and an elastic seal 4 is provided around the periphery of the opening. A protective cover 2 is provided on the base 3 to cover the opening of the base 3. The protective cover 2 includes a top plate 5 covering the opening and a positioning structure provided on its edge. The protective cover 2 is detachably connected to the base 3 through the positioning structure. The positioning structure is a plurality of elastic buckles provided on the side of the top plate 5. The protective cover 2 is vertically buckled downward on the base 3 along a direction perpendicular to the plane of the base 3 and is locked to the side of the base 3 by the elastic buckles, covering the opening of the base to prevent foreign matter from falling into the opening and protecting the elastic seal provided around the opening of the base. After the protective cover is removed from the base in reverse, the ink pad can be installed on the inkjet printer for normal use.

[0027] As shown in the figure, in this embodiment, four elastic buckles are arranged on the side of the top plate 5. The four elastic buckles are four independent elastic arms 8 extending from the opposite side edges of the top plate 5. The elastic arms 8 bend and extend outward and downward, and the lower ends of the elastic arms 8 form an elastic locking portion 81 tending inward. The two elastic arms 8 extending from the same side edges of the top plate 5 are parallel to each other. The four elastic arms 8 are symmetrically arranged in groups of two on the opposite side edges of the top plate 5. When the protective cover and the base are connected, the four elastic arms fasten the side surfaces of the base through the elastic locking portions at the lower ends.

[0028] Furthermore, a plurality of vertically downward positioning arms 9 are extended from the two side edges of the top plate 5, preferably two positioning arms. The base in this embodiment is rectangular with four sides, and the corresponding protective cover is also rectangular, such as Figure 2 The edge of the top plate 5 where the positioning arm 9 is located is vertically adjacent to the edge of the top plate 5 where the elastic arm 8 is located. The elastic arms buckle the two sides of the base to limit the movement of the protective cover along the buckling direction of the elastic locking part, specifically, the movement in the direction perpendicular to the side where the elastic arms are located; the positioning arm cooperates with the elastic arm to limit the protective cover buckled on the base to prevent the protective cover from moving in the vertical buckling direction, specifically, along the direction of the side where the elastic arms are located. The elastic arm and the positioning arm work together to prevent the protective cover from moving horizontally after being buckled in place, and the protective cover can only be buckled vertically downward onto the base or removed vertically upward from the base.

[0029] The inner surface of the bottom end of the positioning arm 9 is an arc-shaped surface 91, and the arc-shaped surface 91 contacts the base to elastically stretch the positioning arm outward, so that the protective cover can be smoothly buckled onto the base. During the buckling process of the protective cover and the base, the arc-shaped wall surface at the bottom end of the positioning arm sticks to the side surface of the base, and the positioning arms and elastic arms on the four sides of the top plate cooperate with each other to limit the installation of the protective cover on the base to prevent the protective cover from shifting during the buckling process.

[0030] Example 2 Figures 4 to 6As shown in the figure, it is also an ink pad with a protective cover. The upper part of the ink pad 1 is also a rectangular base 3. The top of the base 3 is open, and an elastic seal 4 is provided around the periphery of the opening. A detachable protective cover 2 is provided on the base 3 to cover the opening of the base. The protective cover 2 also includes a top plate 5 for covering the opening and a positioning structure provided at its edge. The protective cover 2 is detachably connected to the base through the positioning structure. When the protective cover is connected to the base, it can cover the opening of the base, prevent foreign objects from falling into the opening, and protect the elastic seal around the opening of the base.

[0031] In this embodiment, the positioning structure is a plurality of elastic buckles provided on the side surface of the top plate 5. At least two opposite side walls 10 are provided at the edge of the top plate 5. In this embodiment, it is preferably four side walls 10. The four side walls 10 are pairwise opposite and form a closed border 11 that surrounds a circle. Each side wall 10 extends along the edge of the top plate 5 and extends vertically downward. The elastic buckle is a protrusion 101 on the inner surface of the side wall 10. A protrusion 101 is provided for each of the four side walls. An inner concave 31 that matches the protrusion 101 is provided at each of the four surrounding side surfaces of the base. When the protective cover 2 is buckled to the base 3, the four protrusions 101 are buckled into the four inner concaves 31. When the protective cover 2 and the base 3 are buckled in place, the closed border 11 tightly sleeves on the upper part of the base 3. To facilitate the installation and removal of the protective cover, there are also ribs 13 on the outer surfaces of the four side walls of the closed border to increase the friction force and make the operation easier. There are multiple parallel ribs 13 on each side wall 10. During use, hold the position of the ribs with fingers and pinch the protective cover to operate, buckle it to the base or remove it from the base.

[0032] Embodiment 3 is as Figures 7 to 9 As shown in the figure, it is also an ink pad with a protective cover. The upper part of the ink pad 1 is a rectangular base 3. The top of the base 3 is open, and an elastic seal 4 is provided around the periphery of the opening. A protective cover 2 is provided on the base 3 to cover the opening of the base 3. The protective cover 2 also includes a top plate 5 for covering the opening and a positioning structure provided at its edge. The protective cover 2 is detachably connected to the base 3 through the positioning structure. The difference from Embodiment 1 and Embodiment 2 is that in this embodiment, the protective cover 2 slides along a direction parallel to the plane of the base 3 from the side of the base 3 and is clamped to the base 3. The specific positioning structure is two clamping plates 6 opposite to each other on both sides of the top plate 5. Two opening slots 7 that match the two clamping plates 6 are opened on the side surface of the base 3. To improve the strength of the two clamping plates, a side wall also extends from one side of the top plate 5 corresponding to the ends of the two clamping plates 6 and is integrally butted with the two clamping plates. As shown in the figure, the bottom ends of the clamping plates 6 on both sides of the top plate 5 are bent and extended inward towards the opposite clamping plate 6 to form two opposite sliding rails 61. When the protective cover 2 and the base 3 are clamped, the sliding rails 61 are moved into the slots from the openings of the matching opening slots 7. By using the cooperation of the sliding rails and the slots, the sliding of the protective cover is guided and limited. After the protective cover slides in place, it covers the opening of the base, prevents foreign objects from falling into the opening, and protects the elastic seal around the opening of the base.

[0033] Further, a locking structure is provided between the front end of the sliding rail 61 and the inner end of the open slot 7 to lock the protective cover 2 when it slides into place. The locking structure includes a partition rib 71 provided in the open slot 7 and a notch 12 provided at the front end of the sliding rail 61. As shown in the figure, the partition rib 71 divides the open slot 7 into an outer slot section 72 communicating with the opening and an inner slot section 73 closed at the inner end of the slot. The notch 12 divides the sliding rail 61 into a front locking head section 62 and a rear free section 63. After the protective cover 2 slides relative to the base 3 into place, the locking head section 62 is snapped into the inner slot section 73, the partition rib 71 is inserted into the notch 12, and the free section 63 is snapped into the outer slot section 72. At this time, the two sections separated by the slot and the two sections separated by the sliding rail are matched, and at the same time, the partition rib and the notch are matched to lock the position of the protective cover, so that the position of the protective cover on the base is fixed. When it is necessary to remove the protective cover, the protective cover is translated outward so that the locking head section turns over the adjacent blocking partition rib to disengage from the inner slot section. When the locking head section is completely moved to the outer slot section, the protective cover can slide freely along the outer slot section and be removed from the base.
