Description

Technical Field

[0001] The utility model relates to a structural improvement of a stationery seal, in particular to a seal that can quickly disassemble the printing surface and can be repeatedly refilled with printing ink. Background Art

[0002] Generally, the printing surface of a traditional seal is fixed, so only one type of imprint can be stamped. If multiple types of imprints need to be stamped, multiple seals are required. In certain fields or situations, it is often necessary to use a seal to stamp multiple types of imprints in daily life, but it is very inconvenient to frequently store or carry multiple seals.

[0003] Chinese Patent No. CN208085288U discloses a photosensitive seal with replaceable different ink cartridges. The structure includes a bracket, an ink cartridge, and a photosensitive printing surface. The feature is that the ink cartridge is sleeved inside the bracket and is clamped by the upper card slots on both sides and the buttons provided on both sides of the bracket. The photosensitive printing surface is arranged on the bottom surface of the ink cartridge by a snap ring and is fastened to the ink cartridge by a bottom cover. The button is a snap button with elastic arms on both sides; the snap button is clamped inside the bracket by the elastic arms on both sides, and its button end is elastically slid in the mounting holes on both sides of the bracket; the snap ring is provided with printing buckles on both sides; the ink cartridge is provided with upper card slots, lower card slots, and outer card slots on both sides; the photosensitive printing surface is arranged under the ink cartridge by a snap ring, and the lower card slots on both sides are clamped with the printing buckles; the bottom cover is clamped with the outer card slots of the ink cartridge by the cover buckles on both sides. The disadvantages of this solution are: first, there are two sets of button mechanisms on both sides, with more parts, more complex structure, and more troublesome installation; second, it is often impossible to achieve coordinated pressing operation of the buttons on both sides, which is likely to cause malfunctions in replacing the ink cartridge; third, the buttons on both sides are in a completely exposed state, and it is easy for one side of the button to be touched, causing one side of the ink cartridge to become unhooked and tilted.

[0004] The Chinese patent No. CN211808529 previously applied by the present applicant discloses a seal with a replaceable printing surface. The structure includes a printing frame, a handle, and a printing surface assembly. The handle is slidably fitted on the upper part of the printing frame. The printing surface assembly is slidably fitted in the lower part of the cavity of the printing frame and is in control connection with the handle. The feature is that a vertically movable intermediate connecting member is installed in the cavity of the printing frame. The handle is connected to the intermediate connecting member. A return spring is installed between the intermediate connecting member and the printing frame. Two radially elastic extension feet extending downward are provided on the intermediate connecting member. A radially reduced section is provided at the lower part of the extension feet. Hook heads are provided at the lower ends of the radially reduced sections. Hook holes for tightly engaging with the hook heads are provided on the top surface of the printing surface assembly. The side surface of the extension feet is connected to the side surface of its radially reduced section by a transition inclined surface. A fixed part that can contact the side surface of the extension feet and the side surface of the radially reduced section is provided in the cavity of the printing frame. A fixed inclined surface for cooperating with the transition inclined surface is provided on the top side of the fixed part. When the fixed part contacts the side surface of the radially reduced section, the hook heads of the two extension feet are in tight engagement with the hook holes. When the fixed part contacts the side surface of the extension feet, the two extension feet are radially elastically contracted inward to release the tight engagement between the hook heads and the hook holes. The disadvantage of this solution is that when the lower bottom opening of the printing frame has no contact object, when the handle is collided or accidentally pressed, the printing surface assembly will fall out. Therefore, it is easy to accidentally touch the handle and cause the printing surface assembly to accidentally fall off during use. Summary of the Invention

[0005] In order to overcome the problems in the prior art such as having more parts, a more complex structure, troublesome installation, and being prone to accidental detachment of the printing surface assembly during use, the purpose of the present utility model is to provide an improved seal that can quickly disassemble the printing surface and can be repeatedly refilled with printing ink, which can overcome the defects of the prior art.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A seal that can quickly disassemble the printing surface and can be repeatedly refilled with printing ink, comprising a seal shell, a connecting member, and a printing surface assembly. The printing surface assembly is connected to the seal shell through the connecting member. A handle is provided on the upper part of the seal shell. The printing surface assembly is composed of an assembly frame, an oil storage pad, a printing surface, and a pressing frame. The printing surface exposes the bottom side of the seal shell. Its characteristics are: A hook is provided at the upper end of the connecting member and is fixedly connected to the upper part inside the seal shell. Two hook feet extending downward are provided in the middle of the connecting member. Hook holes that cooperate and are fixed with the outward hook heads of the hook feet are provided on the top side of the printing surface assembly. An outwardly protruding button hole is provided on the side of the seal shell. A button is slidably fitted in the button hole. The outer side surface of the button is flush with the opening of the button hole. Two laterally extending control feet are provided on the inner side surface of the button. The inclined sections on the two control feet are respectively in clamping cooperation with the outer sides of the two hook feet, and the front sections on the two control feet are respectively in releasing cooperation with the outer sides of the two hook feet.

[0007] In the seal shell of the above technical solution, a pad foot with an annular cross-section can be slidably fitted. A compression spring is provided between the pad foot and the seal shell. The bottom side of the pad foot exposes the bottom side of the seal shell and the exposed height is greater than the height at which the printing surface exposes the bottom side of the seal shell.

[0008] In the above technical solution, an outwardly protruding limiting disc can be provided on the lower side of the connecting member. The top surface of the limiting disc supports the top side of the inner cavity of the pad foot, and the bottom surface of the limiting disc resists the top side of the printing surface assembly.

[0009] In the above technical solution, the pad foot can be inside the cavity of the seal shell, and the printing surface assembly can be inside the cavity of the pad foot.

[0010] In the above technical solution, a return spring can be provided between the inner side surface of the button and the connecting member.

[0012] In the above technical solution, a seal cover can be provided on the bottom side of the seal shell.

[0013] In the above technical solution, the fact that the outer side surface of the button is flush with the opening of the button hole means approximately flush.

[0014] The beneficial effects of the present utility model are as follows: First, the shedding of the printing surface assembly is controlled by a single button, with fewer seal parts, a simpler structure, and more convenient installation, avoiding the problem of inconsistent pressing coordination on both sides of the button during operation, which may cause malfunctions in replacing the printing surface assembly. Second, an outwardly protruding button hole is provided on the side of the seal shell, and the button is slidably fitted in the button hole with the outer side surface of the button flush with the general opening of the button hole, avoiding the problem that the button is completely exposed and easily touched, resulting in accidental shedding of the printing surface assembly. Third, two laterally extending control feet are provided on the inner side surface of the button. The inclined sections on the two control feet are in clamping cooperation with the outer sides of the two hook feet, and the front sections on the two control feet are in release cooperation with the outer sides of the two hook feet. Pressing the button can quickly cause the printing surface assembly to fall off, and then quickly install a replaced or ink-added printing surface assembly. Therefore, the seal of the present utility model can quickly disassemble the printing surface and can be repeatedly inked.
