[0001] The utility model relates to the technical field of seal stamping machines, and particularly relates to a continuous stamping structure that does not rebound when pressed. Background Art

[0002] With the development of the social commercial economy, more and more enterprises in the business environment are becoming more standardized. Many enterprises have clear rules and regulations for some relevant documents that need to be stamped within the enterprise and in external cooperation. And a large number of enterprises centralize the relevant seals of the enterprise in one department for management to prevent the seals from being misused or stolen. Since modern enterprises have a large number of documents that need to be stamped, generally a seal stamping machine is selected to stamp the documents. When the existing seal stamping machine is in use, due to a large number of documents in the enterprise, it needs to be used continuously. And because of the structure of the seal stamping machine, when stamping once, the user needs to manually pull the outer shell slide bar from the upper side of the seal stamping machine to the lowest side to achieve the action of opening the seal for stamping. And when stamping continuously, such an operation is time-consuming and laborious, and it is not very convenient to use. The structure needs to be simply adjusted to achieve continuous stamping with only a small movement. Summary of the Utility Model

[0025] To make the technical solution of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0026] Embodiment 1

[0027] Combined with the attached Figure 1-7, a continuous stamping structure that does not rebound when pressed, mainly applied to stamping machines. The continuous stamping structure that does not rebound can be directly set on the existing stamping machine structure. The stamping machine with the continuous stamping structure includes a housing 10. Inside the housing 10, there is a slider control assembly 11. The bottom of the slider control assembly 11 is connected to a stamp clamp 12. A stamp 13 is installed inside the stamp clamp 12. A housing slide bar 14 is slidably arranged on the outside of the housing 10. The housing slide bar 14 cooperates with the slider control assembly 11. When using the stamping machine, by pulling down the housing slide bar 14, the housing slide bar 14 is inserted and cooperated with the slider control assembly 11, so as to drive the slider control assembly 11 to descend by the housing slide bar 14. After the slider control assembly 11 descends, it drives the stamp clamp 12 to descend. When the stamp clamp 12 descends, the stamp clamp 12 descends to drive the stamp 13 to descend. At this time, the stamp 13 completes the stamping work.

[0028] In the existing stamping machine, the slider control assembly 11 of the stamping machine includes a servo motor 20. A gear 21 is rotatably arranged at the bottom of the servo motor 20. The servo motor 20 controls the rotation of the gear 21. The slider control assembly 11 is provided with a lock bracket 22. A lock tongue 23 is slidably arranged inside the lock bracket 22. The lock tongues 23 are preferably two symmetrically arranged ones, and both sides of each lock tongue 23 are also symmetrically structured. A top pin 24 is fixed on both sides of each lock tongue 23. There is a certain space between the two symmetrically arranged lock tongues 23. The space between the symmetrically arranged lock tongues 23 is used to accommodate the gear 21. On the opposite sides of the two symmetrically arranged lock tongues 23 facing each other, racks 25 are symmetrically arranged. The racks 25 are meshed with the gear 21.

[0029] After the gear 21 is meshed with the rack 25, the rotation of the gear 21 can drive the lock tongue 23 to slide inside the lock bracket 22 through the rack 25. By the forward and reverse rotation of the gear 21, one side of the two symmetrically arranged lock tongues 23 can extend out of the lock bracket 22, or retract from the state of extending out of the lock bracket 22 back into the lock bracket 22.

[0030] A mating block 30 that moves inside the housing 10 of the stamping machine is arranged on the housing slide bar 14 of the stamping machine. The mating block 30 located inside the stamping machine 10 is arranged on both sides of the top pins 24 provided on the symmetrically arranged lock tongues 23. The mating block 30 is correspondingly arranged with the top pins 24. A perforation 31 is arranged on the mating block 30. When the lock tongue 23 slides, the lock tongue 23 slides to drive the top pin 24 to slide outwards on both sides and extend out of the lock bracket 22. The top pin 24 extending out of the lock bracket 22 is inserted into the perforation 31 on the mating block 30. At this time, the cooperation between the top pin 24 and the mating block 30 of the housing slide bar 14 is completed.

[0031] At the same time, since the mating block 30 and the housing slide bar 14 are of an integral structure, a through chute 18 for the partial sliding of the fixed connection between the mating block 30 and the housing slide bar 14 is arranged on the housing 10 of the stamping machine.

[0032] A pull-back spring is provided between the slider control assembly 11 in the existing stamping machine and the top of the stamping machine. The pull-back spring is used to pull the slider control assembly 11 upward so that the stamp returns to the inside of the stamping machine housing 10 again.

[0033] Through the above technical solution, when the user needs to stamp, first, the steering gear 20 drives the gear 21 to rotate. The rotation of the gear 21 drives the locking tongue 23 to slide to both sides through the cooperation of the gear 21 and the rack 25. At this time, the top pin 24 on the locking tongue 23 is inserted into the through hole 31 of the mating block 30. The user pulls down the housing slide bar 14, and thus drives the entire slider control assembly 11 to move downward through the top pin 24, thereby completing the stamping action.

[0034] In the continuous stamping structure directly installed in the above technical solution, a movable hole 40 is provided at the lower side position between the through chutes 18 on the housing 10. The movable hole 40 is used for limiting and reciprocating movement during continuous stamping.

[0035] A swing rod space 41 is provided inside the lock bracket 22 below the locking tongue 23. The swing rod space 41 is an annular space. Insertion pin chutes 42 are symmetrically provided in the side wall of the swing rod space 41. The insertion pin chutes 42 penetrate from the swing rod space 41 to both sides. The two insertion pin chutes 42 are symmetrically arranged, and the components installed in the insertion pin chutes 41 are also symmetrically arranged.

[0036] An annular insertion pin outer wall 43 is fixedly provided near the outside in the insertion pin chute 42. An insertion pin 44 slides inside the insertion pin outer wall 43, and the insertion pin 44 can slide inside the insertion pin outer wall 43 and extend out of the insertion pin outer wall 43 and the insertion pin chute 42.

[0037] The insertion pin 44 is arranged corresponding to the movable hole 40. One end of the insertion pin 44 extending out of the insertion pin outer wall 43 and the insertion pin chute 42 is inserted into the movable hole 40. The movable hole 40 has a certain length, which enables the insertion pin 44 to move up and down in the movable hole 40.

[0038] A swing rod 47 is rotatably provided in the swing rod space 41. The swing rod 47 is a partially protruding structure. A curved side wall 48 protruding outward is provided on the side surface of the swing rod 47. The curved side wall 48 is centrally symmetrically arranged on the swing rod 47, and the curved side wall 48 is a partially convex side wall on the swing rod.

[0039] An abutting spherical surface is provided at the inner end of the insertion pin 44, and the abutting spherical surface keeps abutting against the swing rod 47. Since the swing rod 47 is provided with a partially protruding curved side wall 48, when the swing rod 47 rotates, when the abutting spherical surface of the insertion pin 44 does not contact the curved side wall 48, the insertion pin 44 is located inside the insertion pin outer wall 43 and the insertion pin chute 42 and will not extend out of the insertion pin outer wall 43 and the insertion pin chute 42. When the swing rod 47 rotates and the abutting spherical surface of the insertion pin 44 abuts against the curved side wall 48, the insertion pin 44 extends out of the insertion pin outer wall 43 and the insertion pin chute 42.

[0040] The gradually protruding structure of the curved side wall 48 is such that when the abutting spherical surface of the bolt 44 comes into initial contact with the curved side wall 48, the bolt 44 starts to extend out of the bolt chute 42. As the swing rod 47 rotates, the abutting spherical surface of the bolt 44 slides on the curved side wall 48. Due to the gradually protruding structure of the curved side wall 48, the part of the bolt 44 extending out of the bolt chute 42 gradually elongates.

[0041] At the same time, the curved side wall 48 on the swing rod 47, the swing rod 47 itself, and the protruding part of the curved side wall 48 all have linear transitions, enabling the extension of the bolt 44 to be a gradual extension without being too abrupt.

[0042] An outwardly expanding protrusion 45 is provided inside the bolt 44. The outwardly expanding protrusion 45 is an annular protrusion and is located at the inner end of the bolt 44 within the bolt chute 42. A spring 46 is provided between the outwardly expanding protrusion 45 and the inner end face of the outer wall 43 of the bolt. The elastic force of the spring 46 continuously exerts a force on the bolt 44 to move inwardly towards the inner side of the bolt chute 42 by pressing the outwardly expanding protrusion 45, so that the abutting spherical surface of the bolt 44 can maintain contact with the swing rod 47. In this way, only when the swing rod 47 rotates to a position where the curved side wall 48 abuts against the abutting spherical surface of the bolt 44 can the bolt 44 extend out of the outer wall 43 of the bolt and the bolt chute 42.

[0043] A connecting hole is provided at the center of the swing rod 47. A connecting rod on the servo 20 can be directly inserted into the connecting hole, so that the servo 20 directly drives the swing rod 47. At this time, the connecting hole is preferably a square hole and the connecting rod is a square rod.

[0044] When the user pulls down the outer shell slider 14 to drive the slider control assembly 11 to move downward as a whole through the top pin 24 to complete the stamping action, the servo 20 is activated to further drive the swing rod 47 to rotate through the connecting rod. The rotation of the swing rod 47 causes the bolt 44 to extend out of the outer wall 43 of the bolt and the bolt chute 42, and the bolt extending out of the outer wall 43 of the bolt and the bolt chute 42 is inserted into the movable hole 40.

[0045] At this time, since the bolt 44 is in the movable hole 40, the movable hole 40 restricts the bolt 44 so that it cannot escape from the movable hole 40, thus preventing the slider control assembly 11 from rising. And since the servo 20 does not reverse, the locking tongue 23 is still in the through hole 31 on the mating block 30 at this time. Therefore, the user can perform re-stamping of the seal by pressing the outer shell slider 14 first. Since the length of the movable hole 40 is limited and the movable hole 40 is located below the through chute 18, the user only needs to move the outer shell slider 14 a short distance to achieve re-stamping of the seal. The user can perform continuous stamping of the seal without the seal rebounding by operating the outer shell slider 14 up and down for a short distance.

[0046] When stamping is not required, the servo 20 reverses, enabling the bolt 44 to withdraw from the movable hole 40 and the locking tongue 23 to withdraw from the perforation 31. At this time, the slider control assembly 11 rises, and the stamp returns to the working position.

[0047] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
