Description

Technical Field

[0001] The utility model relates to the technical field of automatic ink replenishment of seals, in particular to a novel oracle-bone seal capable of automatically replenishing ink. Background Art

[0002] A seal is a stationery used to leave an imprint on a document or object, usually for identification or signature. When a seal is used, it is usually dipped in paint before printing, that is, the ink pad and the seal body are separate. Such a seal needs to be taken separately before each use, which increases the complexity of operation, especially when frequent stamping is required, which greatly reduces work efficiency. With the development of technology, seals that automatically replenish ink are gradually emerging. However, most of the existing automatic ink-returning seals directly connect the built-in ink storage device and the seal body through pipes and the like. Although protected by a cover, the seal body cannot avoid being exposed to the air for a long time, and the ink is easy to volatilize. Therefore, the ink storage device will continuously supply ink to the seal surface, so that the seal body is immersed in ink for a long time. This situation easily leads to ink penetration, expansion and aging of the seal body, reducing the service life of the seal. In order to realize the automatic ink return function, the automatic ink return seal is usually equipped with mechanical structures such as gears. Some equipment is also driven by electronic components. The structure is precise and the movement is accurate, but too many parts lead to an increase in the overall cost. The internal structure is too complicated, requiring higher maintenance costs and more frequent maintenance. When not used for a long time, the ink will easily become dry due to volatilization, and it is necessary to add or replace ink to the ink storage device when using it again. Utility Model Content

[0003] (I) Technical problems solved: In view of the deficiencies in the prior art, the utility model provides a new type of oracle bone script seal that automatically replenishes ink, which has the advantage of an ink storage device and a seal body that are separated, and the ink can be replenished immediately after each stamping, thus solving the problem of the seal body being unusable due to expansion and aging caused by being immersed in a large amount of ink for a long time.

[0004] (ii) Technical solution: To achieve the above-mentioned purpose of automatically replenishing ink, the utility model provides the following technical solution: a new type of oracle bone script seal with automatic ink replenishment, comprising an outer shell, a bottom shell and a seal body, the bottom shell is equipped with an automatic inking system, the automatic inking system comprises a bracket, an ink storage tank, a push rod and a spring, the bottom shell is fixedly installed with a bracket, the bracket is equipped with an ink storage tank, the ink storage tank comprises a tank mouth, a cover, a push rod channel, a ventilation pipe and an ink outlet pipe, the ventilation pipe is fixedly installed with a first one-way valve, the ink outlet pipe is fixedly installed with a second one-way valve, and the outer shell is fixedly installed with a push rod.

[0005] Preferably, bottom grooves are provided along both sides of the long sides below the bottom shell, and the bottom shell and the printing body are connected through the bottom grooves.

[0006] Preferably, the opening of the first one-way valve inside the ventilation tube points to the inside of the ink storage tank, and the opening of the second one-way valve inside the ink outlet tube points to the outside of the ink storage tank.

[0007] Preferably, the first one-way valve and the second one-way valve are made of organic material.

[0008] Preferably, the installation position of the push rod is located on the center line of the push rod channel.

[0009] Preferably, there are sliding grooves and fixing holes on both sides of the bottom shell, and limiting points and fixing pins are installed on both sides of the outer shell.

[0010] Preferably, the fixing pin is connected to the housing via a rotating shaft.

[0011] (III) Beneficial effects: Compared with the prior art, the utility model provides a new type of oracle bone script seal that automatically replenishes ink, which has the following beneficial effects:

[0012] 1. The new type of oracle bone script seal with automatic ink replenishment has an automatic inking system separated from the seal body. Through the cooperation of the ejector rod and the spring, the ink storage tank will replenish ink to the seal body only when stamping, realizing the replenishment of ink as soon as it is used, avoiding the possible expansion and aging of the seal body and ink penetration caused by long-term immersion in a large amount of ink, thereby extending the service life of the seal body.

[0013] 2. The automatic inking system uses two one-way valves in the vent pipe and the ink outlet pipe. When the shell is pressed, the ejector pushes the ink into the ink outlet pipe through the ejector channel. At this time, the first one-way valve in the vent pipe is closed to keep the pressure from leaking. After the stamping is completed, the spring lifts the shell. When the ejector moves outward, the air pressure in the tank decreases, the first one-way valve in the vent pipe opens to allow external air to enter, and the second one-way valve in the ink outlet pipe closes to prevent ink from flowing back. Compared with other technical structures, this structure is simple in construction, without electronic devices and mechanical devices such as gears, with high reliability, stable operation, easy maintenance, and low long-term use cost.

[0014] 3. In the automatic inking system, the ejector rod is always located in the ejector rod channel. When the seal is not in use, the one-way valves in the vent pipe and the ink outlet pipe are not affected by external forces and are in a closed state. At this time, the ink storage tank is in a sealed state, and the ink inside does not contact the external atmosphere. The ink is not easy to evaporate and can be well preserved. The ink is not easy to overflow, and it is more convenient and safer to carry. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 The invention discloses a novel oracle bone script seal with automatic ink replenishment, comprising a shell 1, a bottom shell 2 and a seal body 3. The bottom shell 2 is provided with an automatic inking system. The main structure thereof comprises a bracket 4, an ink storage tank 6, a tank opening 8, a cover 7, a push rod 14, a push rod channel 9, a vent pipe 10, an ink outlet pipe 11 and a spring 15. The push rod 14 is fixedly connected to the inside of the shell 1. A clearance fit is adopted between the push rod 14 and the push rod channel 9, so that the push rod 14 can slide against the push rod 14 while preventing the air from escaping from the narrow gap between the push rod 14 and the push rod channel 9. The installation position of the push rod 14 is located at the push rod channel 9. On the center line of channel 9, the ejector rod can move downward to compress the air in the tank during stamping, avoiding the influence of external forces in other directions, making the stamping process smoother and increasing the service life of the ejector rod; there is a longitudinally arranged slide groove 5 on each side of the bottom shell 2, and a limit point 16 on each lower position on both sides of the inside of the outer shell 1. During stamping, the limit point 16 moves up and down in the slide groove 5, limiting the moving distance of the outer shell 1 and the ejector rod 14 inside the outer shell 1, preventing the ejector rod 14 from escaping from the ejector rod channel 9, and also preventing the outer shell 1 from separating from the bottom shell 2 under the elastic force of the spring 15.

[0024] See also Figure 2The bracket 4 is fixedly installed inside the bottom shell 2, and an ink storage tank 6 is installed above the bracket 2. The ink storage tank 6 is provided with a tank mouth 8, a push rod channel 9, a ventilation pipe 10 and an ink outlet pipe 11. The tank mouth 8 is equipped with a cover 7. After the ink is filled in the tank mouth 8, the cover 7 can achieve a sealing effect. A first one-way valve 12 is provided in the ventilation pipe 10, and the opening of the first one-way valve 12 points to the inside of the ink storage tank 6. A second one-way valve 13 is provided inside the ink outlet pipe 11, and the opening of the second one-way valve 13 points to the outside of the ink storage tank 6. The two one-way valves with different directions cooperate with each other to seal the ink storage tank while ensuring that the ink in the tank can only go out but not in.

[0025] See also Figure 2 and Figure 5 There are two locating pins 17 on each side of the shell 1, and the locating pins 17 are connected to the shell 1 through a rotating shaft 18. There are two locating holes 19 on each side of the bottom shell 2. When in use, the locating pins 17 can be turned up through the rotating shaft 18, and the pins can be placed outward without affecting the normal use of the seal; when the seal is not used for a long time, the four locating pins 17 are turned down and inserted into the corresponding locating holes 18, and no relative movement occurs between the shell 1 and the bottom shell 2. Since the ejector rod 14 is always inserted in the ejector rod channel 9, the first one-way valve 12 and the second one-way valve 13 remain closed without external force. At this time, the ink storage tank 6 is in a sealed state, and the ink inside can be well preserved and will not volatilize due to communication with the outside. The ink inside the sealed ink storage tank 6 will not overflow due to external shaking and other factors, thereby improving portability and safety.

[0026] See also Figure 4 A bottom groove 20 is provided at the bottom of the bottom shell 2, and the stamp body 3 and the bottom shell 2 are movably connected through the bottom groove 20. The stamp body 3 can be replaced. Different contents can be printed by replacing different stamp bodies, thereby achieving the purpose of multiple uses of one stamp. This not only saves costs, but also simplifies the replacement process, improves work efficiency, and at the same time extends the overall service life of the stamp and reduces the long-term use cost.

[0027] See also Figure 6 The first one-way valve 12 and the second one-way valve 13 each have three flaps of material. When the three flaps are closed, they are arched. The protruding direction of the flap tip is the one-way conduction direction of the one-way valve. The first one-way valve 12 and the second one-way valve 13 are made of organic material, usually made of rubber. The valve flaps made of organic material are moderately soft and hard, and can achieve the one-way conduction effect with a little processing. They are low in price, reduce the complexity of the entire system, and have a long service life.

[0028] Working principle: After the seal is assembled, the outer shell 1 is forced upward by the elastic force of the internal spring 15, the limit points 16 on both sides of the outer shell 1 are located at the top of the slide groove 5, the outer shell 1 is in a high position, and the push rod 14 is located in the push rod channel 9. When stamping, the downward external force on the outer shell 1 is greater than the upward elastic force of the spring 15, the outer shell 1 moves downward, and the push rod 14 moves downward through the push rod channel 9. The space inside the ink storage tank 6 is compressed, and the gas and liquid in the tank are under pressure, the internal pressure increases, and the pressure in the tank is greater than the external atmospheric pressure. The opening of the first one-way valve 12 in the ventilation pipe 10 points to the inside of the ink storage tank 6 and is kept closed by the internal pressure, and the pressure does not leak from here. The opening of the second one-way valve 13 in the ink outlet pipe 11 points to the outside of the ink storage tank 6. Under the action of the internal pressure, the second one-way valve 13 opens outward, and ink flows out of the ink outlet pipe 11 flows out and flows to the printing body 3 through the pipeline to replenish the printing body 3. When the limit point 16 is located at the bottom of the slide groove 5, the shell 1 is in the lower position and no longer moves downward. The stamping is completed, the ink storage tank 6 stops replenishing ink to the printing body 3, and the hand no longer applies pressure to the shell 1. The spring 15 is compressed and the elastic direction is upward. The shell 1 and the push rod 14 move upward. At this time, the internal space of the ink storage tank 6 becomes larger, and the amount of substance remains unchanged, so the internal pressure decreases, and the pressure in the tank is less than the external atmospheric pressure. The second one-way valve 13 inside the ink outlet tube 11 is in a closed state due to the external atmospheric pressure to prevent the ink in the tube from flowing back. The first one-way valve 12 in the ventilation tube 10 opens inward under the action of the external atmospheric pressure, and air enters the ink storage tank 6 to keep the pressure inside and outside the tank balanced. After the shell 1 returns to a high position again, the stamping process is completed.

[0029] In summary, in the novel oracle seal with automatic ink replenishment, the automatic inking system is separated from the printing body 3. Through the cooperation of the push rod 14 and the spring 15, the ink storage tank 6 will replenish ink to the printing body 3 only when stamping, so that the printing body 3 can be replenished immediately after use, and the swelling, aging, ink penetration and other problems of the printing body 3 that may occur due to long-term immersion in a large amount of ink are avoided, thereby extending the service life of the printing body 3. The automatic inking system, through the cooperation of the two first one-way valves 12 and 13 in the vent pipe 10 and the ink outlet pipe 11, when the shell 1 is pressed, the push rod 14 presses the ink into the ink outlet pipe 11 through the push rod channel 9, at this time, the one-way valve 11 in the vent pipe 10 is closed to keep the pressure from leaking out, and the spring 15 lifts the shell 1 after stamping is completed. When the push rod 14 moves outward, the air pressure in the tank decreases, the first one-way valve 12 in the vent pipe 10 opens to allow air to enter, and the second one-way valve 13 in the ink outlet pipe 11 is closed to prevent ink from flowing back. Compared with other technical structures, this structure is simple in structure, has no electronic devices and mechanical devices such as gears, has high reliability, stable operation, easy maintenance, reduces long-term use costs, and improves work efficiency. In this automatic inking system, the push rod 14 is always located in the push rod channel 9. When the seal is not in use, the first one-way valve 12 in the vent pipe 10 and the second one-way valve 13 in the ink outlet pipe 11 are not affected by external forces and are in a closed state. The ink storage tank 6 is in a sealed state, and the ink inside does not contact the external atmosphere. The ink is not easy to volatilize and can be well preserved. The ink will not overflow, making it more convenient and safe to carry.
