Description

Technical Field

[0001] The utility model relates to the technical field of locking a bottom shell of a stamp affixer, in particular to a locking mechanism of a bottom shell of a stamp affixer. Background Art

[0002] A stamp stamper is a tool used for stamping. It usually installs a seal on a specific device to facilitate the user to perform stamping operations. In administrative agencies, a large number of official documents need to be stamped on a daily basis, such as notices, replies, letters, etc. The stamp stamper can complete the stamping task quickly and accurately, improve the efficiency of document processing, and ensure the standardization and authority of the documents. The bottom shell of the stamp stamper is the outer shell structure located at the bottom of the stamp stamper. A special structure is provided inside the bottom shell of the stamp stamper to fix the seal, so that the seal can be stably placed in the stamp stamper.

[0003] A threaded ring is provided on the top inner edge of the bottom shell of the stamp stamper, and a threaded column is fixedly installed at the top center of the base. By rotating the bottom shell, it is tightened with the threaded column of the base, thereby achieving locking of the bottom shell. Its working principle is: when the bottom shell is rotated, the threaded ring rises or falls along the spiral line of the threaded column. Due to the close fit between the threads, a large friction force is generated, which prevents the relative movement between the bottom shell and the base, thereby firmly fixing the bottom shell on the base. During the tightening process, the threaded column is subjected to tensile force, and a clamping force is generated between the bottom shell and the base, making them tightly combined together.

[0004] In the prior art, the bottom shell of some stamp stampers is locked by a threaded connection. When the stamp stamper needs to be used for stamping, the lock between the bottom shell and the stamp stamper needs to be released. The bottom shell needs to be loosened during the unlocking process, and multiple rotations are required to complete the operation. The operation is time-consuming. In scenarios where the stamp stamper needs to be used frequently, it will affect work efficiency. Therefore, a locking mechanism for the bottom shell of the stamp stamper is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 The bottom shell 1 is a kind of bottom shell locking mechanism of the present invention, and bottom shell 1 is the basic frame of the bottom shell locking mechanism of the bottom shell of the stamping device, and provides stable installation and operation space for various internal components, and lower round block 9. The left and right sides of the interior of the bottom shell 1 are slidably connected with sliding rods 2. The sliding rods 2 can move in the bottom shell 1, so as to drive other components to work together, and play a key transmission role in the locking and unlocking operations of the bottom shell. The outer far side of the sliding rod 2 is fixedly connected with a baffle 1 3. The baffle 1 3 can prevent the sliding rod 2 from sliding excessively outward and play a limiting protection role. The outer close side of the baffle 1 3 contacts the outer side of the bottom shell 1. The outer side of the sliding rod 2 is sleeved with a spring 1 4. The spring 1 4 provides elastic support for the reset of the inclined block 5, so that the inclined block 5 can return to its initial position in time after being forced to move, thereby ensuring the stability and reliability of the bottom shell locking mechanism.

[0033] One end of the spring 1 is fixedly connected to the left and right sides of the interior of the bottom shell 1, and the adjacent side of the sliding rod 2 is fixedly connected to the inclined block 5. The special inclined surface structure of the inclined block 5 can convert the vertical movement of the lower round block 9 into its own horizontal movement when it contacts the lower round block 9, thereby realizing effective clamping and loosening of the lower round block 9. The outside of the inclined block 5 is slidingly connected to the inside of the bottom shell 1, and the other end of the spring 1 is fixedly connected to the adjacent side of the inclined block 5. The inside of the bottom shell 1 is slidingly connected to a connecting column 6, and the outer bottom end of the connecting column 6 is fixed with a spring 2 7. The spring 2 7 plays a role of buffering and resetting during the locking process. The bottom end of the spring 2 7 is fixedly connected to the upper round block 8. The upper round block 8 cooperates with the lower round block 9 to transmit pressure when stamping, and plays an auxiliary role in the locking and unlocking process of the bottom shell. Its contact interaction with the oblique block 5 can realize the stable fixation and release of the lower round block 9 in the bottom shell 1. The outer part of the upper round block 8 is slidably connected to the inner part of the bottom shell 1, and the outer part of the upper round block 8 contacts the adjacent side of the oblique block 5. The outer part of the lower round block 9 is slidably connected to the inner part of the bottom shell 1, and the outer part of the lower round block 9 contacts the adjacent side of the oblique block 5. The inner bottom end of the lower round block 9 is fixedly connected with a seal 10. The seal 10 is the core functional component of the stamp stamper. Through the operation of the entire mechanism, the required pattern or text can be accurately printed on the target object;

[0034] The external top end of the connecting column 6 is fixedly connected with a pressing assembly for pushing. The pressing assembly includes a connecting rod 11. The connecting rod 11 serves to connect the handle 12 and the connecting column 6. It can transmit the pressing force on the handle 12 to the connecting column 6 evenly and stably, ensuring that the connecting column 6 can move vertically and smoothly when subjected to force. The bottom end of the connecting rod 11 is fixedly connected to the top end of the connecting column 6. The top end of the connecting rod 11 is fixedly connected with the handle 12. The user can easily control the locking operation between the stamper and the bottom shell by pressing the handle 12.

[0035] Reference Figure 1 、 Figure 3 、 Figure 4 The interior of the connecting column 6 is fixedly connected with a sleeve rod 13, and a sliding groove 14 is opened inside the sleeve rod 13. The sliding groove 14 provides a guide for the up and down sliding of the connecting rod 15 to ensure that the connecting rod 15 always maintains linear motion during the movement to avoid offset or jamming. The interior of the sliding groove 14 is slidably connected with the connecting rod 15. When the connecting rod 15 moves up and down on the connecting column 6, it can slide accordingly in the sliding groove 14 to transmit the impact force received by the connecting column 6 to the spring three 17. The top of the connecting rod 15 is fixedly connected with a baffle two 16. The baffle two 1 6 plays a limiting role when sliding in the sliding groove 14, preventing the connecting rod 15 from sliding upward excessively and disengaging from the sliding groove 14. The outer part of the baffle 2 16 is slidably connected to the inner part of the sliding groove 14. The inner top of the sliding groove 14 is fixedly connected with a spring 3 17. One end of the spring 3 17 is fixedly connected to the outer part of the baffle 2 16. When encountering greater resistance during the stamping process, the spring 3 17 can absorb and buffer the impact force transmitted by the connecting rod 15, effectively protecting the seal 10 and the entire stamping device mechanism from damage, and extending the service life of the stamping device.

[0036] Working principle: When the stamp stamper needs to be locked with the bottom shell, first push the connecting column 6 to slide downward along the bottom shell 1, which will then drive the lower round block 9 to slide inside the bottom shell 1, and then push the inclined block 5, which will then cause the spring 14 to be squeezed, pushing the inclined block 5 to slide to both sides inside the bottom shell 1, and the inclined block 5 drives the sliding rod 2 fixedly connected to it to slide in opposite directions on the left and right sides inside the bottom shell 1, and the sliding rod 2 drives the baffle 13 to move synchronously, at this time the spring 14 It will reset, and then drive the inclined block 5 to engage with the top of the lower round block 9 to achieve rapid locking of the bottom shell. When it is to be released, press the handle 12 again, and then the upper round block 8 will be driven to contact the inclined block 5 under the tension of the spring 2 7, and then it will slide over the inclined block 5 and fit with the lower round block 9, and then pull the connecting column 6, the inclined block 5 will slide outside the spring 2 7 and the lower round block 9, and then the lower round block 9 can be pulled out, and then the spring 2 7 will drive the upper round block 8 to rise, releasing the lock of the stamper on the external bottom shell.

[0037] When performing the stamping operation, the handle 12 is pressed, and the handle 12 drives the connecting rod 11 to move downward, and the connecting rod 11 drives the connecting column 6 to move downward. During the stamping process, if a large resistance is encountered, the spring three 17 in the sleeve rod 13 inside the connecting column 6 plays a buffering role. When the connecting column 6 moves downward, the connecting rod 15 slides upward inside the sliding groove 14, and the spring three 17 is compressed, thereby buffering the impact force generated during stamping, preventing the seal 10 or other components of the stamping device from being damaged due to excessive impact force.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
