Description

Technical Field

[0001] The invention belongs to the technical field of mold printing devices, in particular to a counting stamp which is simply modified from an ordinary stamp. Background Art

[0002] A seal is used to stamp on documents to indicate identification or signature. Formal letters, documents, and reports issued by a company or unit to the outside world use the seal of the unit, which is the official seal. Documents stamped with the official seal have legal effect.

[0003] In order to effectively manage the use of seals, timely grasp the use of seals, accurately and reliably record the number of times seals are used, and prevent people from stealing seals, the Chinese utility model patent "A digital counting seal" (application number: 201721227170.9, authorization announcement number: CN 207207494U, publication date: 2018-04-10) discloses a digital counting seal, including a handle, a mechanical counting device, a support platform, a seal seat, a seal cover and a digital counting unit, the upper end of the support platform is fixedly connected to the support cylinder extending from the lower end of the handle, the mechanical counting device and the digital counting unit are relatively arranged in the support cylinder, the mechanical counting device is transmission-connected to the support platform, the seal seat is arranged in the support platform, the lower end of the support platform is engaged with the seal cover and the seal seat is covered in the support platform, and at least an electronic door lock is arranged at the engagement point between the lower end of the support platform and the seal cover. The counting seal structure is too complicated and difficult to promote and use.

[0004] Chinese utility model patent "A financial seal capable of counting" (application number: 201620207663.5, authorization announcement number: CN 205395489U, publication date: 2016-07-27) discloses a financial seal capable of counting, which includes: a seal body, a cavity is provided at the center, and a fixed contact piece is provided at the top of the cavity; a guide post is slidably arranged in the cavity, and a movable contact piece is provided at the upper end of the guide post; a wireless transmitter is arranged on the seal body and electrically connected to the fixed contact piece, and when the movable contact piece abuts against the fixed contact piece, the wireless transmitter sends an electrical signal; a wireless receiver, which is used to receive the electrical signal from the wireless transmitter; a counter, which is electrically connected to the wireless receiver, and is used to record the number of times the wireless receiver receives the electrical signal and count it; a power supply, which is connected to the fixed contact piece and the counter, and is used to provide electrical energy; wherein, when the movable contact piece at the upper end of the guide post abuts against the fixed contact piece, the lower end surface of the guide post is flush with the lower end surface of the seal body. In order to count, the seal needs to have a hole on the bottom to facilitate the extension of the guide post, which results in a gap in the middle of the seal, seriously affecting the integrity of the seal pattern.

[0005] In addition, there are still a large number of seals without counting functions in use in real life. If all these ordinary seals are replaced with new counting seals, not only will the economic losses be huge, but there will also be huge legal risks in how to destroy or seal the original seals. Summary of the invention

[0006] The purpose of the invention is to provide a counting seal with simple structure and complete seal pattern.

[0007] Furthermore, ordinary seals can be transformed into counting seals at a relatively low cost.

[0008] The technical solution to achieve the purpose of the present invention is:

[0009] A counting seal comprises a seal body 1, and at least two direct-acting travel switches 2 arranged around the seal body 1; the free end of the push rod 21 of the travel switch 2 protrudes from the seal surface 11 of the seal body 1; and a counting device 3, which is connected to the travel switch 2 signal.

[0010] Preferably, the travel switch 2 is detachably fixedly connected to the seal body 1 .

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] 1. Simple structure: The present invention arranges a travel switch 2 around the seal body 1, and the free end of the push rod 21 of the travel switch 2 protrudes from the seal surface 11 of the seal body 1, so as to realize the counting of each stamping. The present invention has a simple structure, low cost and good reliability.

[0013] 2. Complete seal pattern: multiple travel switches 2 are arranged around the seal body 1, and counting triggering can be achieved without opening holes on the bottom surface of the seal, thereby ensuring the integrity of the seal pattern.

[0014] 3. Convenient for transformation of existing seals: As an improvement, a simple mechanism such as a clamp 4 is used to detachably fix the travel switch 2 to the seal body 1, so that the existing common seals in large quantities can be upgraded to new counting seals, which is simple, easy, low-cost, and does not affect the pattern of the existing seals.

DETAILED DESCRIPTION

[0022] like Figure 1 As shown, the counting seal of the present invention comprises a seal body 1, and also comprises at least two direct-acting travel switches 2 arranged around the seal body 1;

[0023] The free end of the push rod 21 of the travel switch 2 protrudes from the seal surface 11 of the seal body 1;

[0024] It also includes a counting device 3, which is connected to the travel switch 2 by signal.

[0025] Preferably, the travel switch 2 is detachably fixedly connected to the seal body 1 .

[0026] As an implementation method for realizing a detachable fixed connection between the travel switch 2 and the seal body 1 , the invention further includes at least one clamp 4 , through which the travel switch 2 is detachably fixedly connected to the seal body 1 .

[0027] By detachably and fixedly connecting the travel switch 2 to the seal body 1, the common seals currently in large quantities can be upgraded to new counting seals, which is simple, easy, low-cost, and does not affect the patterns of the existing seals.

[0028] Preferably, the number of the travel switches 2 is four to six.

[0029] Preferably, the travel switches 2 are evenly arranged along the outer circumference of the seal body 1 .

[0030] Four to six keys are evenly arranged along the outer circumference of the seal body 1, which not only ensures that the structure is not too complicated, but also ensures the reliability of counting.

[0031] Preferably, the counting device 3 is detachably fixedly connected to the seal body 1 .

[0032] The counting device 3 is detachably fixedly connected to the seal body 1, which is convenient for the production and assembly of new seals and more conducive to the transformation and upgrading of ordinary seals.

[0033] As an example, Figure 2 As shown, the travel switch 2 includes a housing 20, a push rod 21 arranged in the housing 20, a moving contact 22, and a stationary contact 23 matching the moving contact 22; the free end of the push rod 21 extends out of the lower end of the housing 20 and protrudes from the seal surface 11 of the seal body 1, and the other fixed end is connected to the moving contact 22.

[0034] The push rod 21 is slidably arranged with the housing 20 and partially extends out of the top surface of the housing 20. The push rod 21 is linked with the moving contact 22, and the static contact 23 and the moving contact 22 are in a normally open or normally closed state. When stamping, the paper surface first contacts the free end of the push rod 21, and the push rod 21 gradually moves toward the upper part of the housing 20. The movement of the push rod 21 changes the position of the moving contact 22, and the moving contact 22 and the static contact 23 are closed or disconnected, thereby realizing the electrical circuit from the normally open state to the normally closed state, or from the normally closed state to the normally open state.

[0035] As an improvement, Figure 3 As shown, the push rod 21 of the travel switch 2 is perpendicular to the printing surface 11 , and the free ends of every two adjacent push rods 21 are fixedly connected by an arc-shaped rigid sheet 211 .

[0036] When the push rod 21 of the travel switch 2 is perpendicular to the seal surface 11, the gap between the push rods is relatively large, and it is possible to push the paper upward against the seal surface 11 by hand without touching the push rod 21, so as to achieve the purpose of stealing the seal. At the same time, the push rods 21 are independent of each other and have poor stability. After the free ends of adjacent push rods 21 are fixedly connected in pairs by an arc-shaped rigid sheet 211, the stability of the push rods 21 is enhanced, and there is no gap between the push rods, which greatly increases the difficulty of stealing. In particular, when there are four travel switches 2, the effect is better.

[0037] As another improvement, Figure 4 As shown, the free end of the push rod 21 of the travel switch 2 is inclined toward the center of the printing surface 11. As a further improvement, the free end of the push rod 21 is provided with a sliding wheel 212.

[0038] The axis of the push rod 21 is not parallel to the axis of the seal, so that the free end is inclined toward the center of the seal surface 11. When not stamping, the free end of the push rod 21 covers part of the seal surface 11, which greatly increases the difficulty of stealing the seal without triggering the counting. A sliding wheel (212) is provided at the free end of the push rod 21 to facilitate sliding outwards when stamping. At the same time, the axis of the push rod 21 is not parallel to the axis of the seal, and the end of the travel switch 2 away from the seal surface is unfolded outwards, which is convenient for holding the seal.

[0039] As an example, Figure 5As shown, the counting device 3 includes a single chip computer 31 , and a display module 32 , a battery module 33 , a storage module 34 and a clock module 35 electrically connected to the single chip computer 31 .

[0040] As a further improvement, a vibration sensor 37 electrically connected to the single chip computer 31 is also included.

[0041] The vibration sensor 37 is used to detect the movement of the seal and store it to facilitate the user to analyze and monitor the use of the seal.

[0042] As a further improvement, a camera module 38 electrically connected to the single chip computer 31 is also included.

[0043] The camera module 38 is used to capture the content of the stamp when stamping, and store it to facilitate the user to analyze and monitor the use of the stamp.

[0044] like Figure 5 As shown, a communication module 36 for uploading data to a computer or a mobile phone may also be included.

[0045] The working process of the present invention is as follows:

[0046] When stamping, since the lower end surface of the push rod 21 of the travel switch 2 is higher than the lower end surface of the seal body 1, the lower end surface of the push rod 21 first contacts the paper, and the push rod 21 is pressed upward by the paper, and the moving contact 22 is linked. The push rod 21 moves to switch the normally closed state and the normally open state of the travel switch 2. The single-chip microcomputer 31 detects the signal output by the travel switch 2 and counts. The display module 32 displays the count value, and at the same time obtains the time from the clock module 35, and stores the count and time data in the storage module 34. The communication module 36 uploads the data to a computer or mobile phone. The single-chip microcomputer 31 can also detect the movement of the seal through the vibration sensor 37 and store it, so as to facilitate the user to analyze the use of the seal. The single-chip microcomputer 31 can also use the camera module 38 to shoot the stamp content when stamping and store it, so as to facilitate the user to analyze the use of the seal.
