Description

Technical Field

[0001] This utility model relates to the field of photosensitive stamp devices, and in particular to an anti-skew photosensitive stamp. Background Technology

[0002] As is widely known, photosensitive stamps are a special type of stamp whose stamp head is made of a material sensitive to ultraviolet light. When the stamp head is exposed to ultraviolet light, the photosensitive material undergoes a chemical reaction, thus inking the stamp. This technology has certain application prospects in some special occasions and needs, such as those requiring anti-counterfeiting verification and security testing.

[0003] Chinese patent CN222246618U describes an ink-refilling stamp, including a stamp base, a reservoir seat mounted on the stamp base, an internal groove in which an ink reservoir pad is engaged, and a stamp shell plate on the reservoir seat. However, in actual use, the following problems still exist:

[0004] While pressing down vertically to stamp ensures a clear imprint, it requires the user's arm to remain suspended throughout the process, which can easily lead to arm soreness with continuous operation. If pressing down by rotating the wrist can alleviate fatigue, the area of ​​the stamp near the wrist will contact the area to be stamped first when the wrist is rotated. This results in uneven imprints due to the heavier ink in the area near the wrist when rotating and pressing down. Additionally, tilting the wrist downwards at the initial pressing down can easily cause the imprint to be skewed.

[0005] Therefore, a skew-resistant photosensitive stamp is proposed. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide an anti-skew photosensitive stamp.

[0007] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0008] An anti-skew photosensitive stamp includes a housing, a stamp, a handle, and a compartment cover. The housing has a downward-opening cavity, and a mounting hole is located at the top of the housing. The bottom end of the handle is located within the mounting hole and is detachably and fixedly connected to the housing. The stamp is located within the cavity of the housing. The compartment cover is connected to the bottom end of the housing. An anti-skew positioning and pressing ink-filling component is provided within the housing. This component includes a limiting post, a positioning ring, a pushing ring, a fixing post, a force-equalizing pressing assembly, and an ink-filling assembly. The top end of the limiting post is fixedly connected to the top end of the inner wall of the housing, and the inner wall of the pushing ring is fixedly connected to the limiting post. The outer wall of the positioning post is slidably connected, and a plurality of fixed posts are provided. The fixed posts are evenly distributed on the pushing ring along the axis of the pushing ring. The top end of the fixed post is fixedly connected to the lower surface of the pushing ring, and the bottom end of the fixed post is connected to the upper surface of the stamp. The outer wall of the positioning ring is slidably connected to the inner wall of the housing. The fixed end of the uniform force pressing component is connected to the upper surface of the positioning ring, and the movable end of the uniform force pressing component is connected to the pushing ring. The fixed end of the ink filling component is located below the limiting post and connected to the fixed post, and the movable end of the ink filling component is connected to the limiting post.

[0009] The force-equalizing pressing assembly comprises several components, which are evenly distributed circumferentially on the positioning ring along its axis. Each component includes a push rod, a connecting rod, a connecting tube, a rotating shaft, a first spring, a second spring, and an extension tube. A sliding groove is provided at the top of the inner wall of the housing. The bottom end of the push rod is fixedly connected to the upper surface of the positioning ring, and the top end of the push rod is slidably connected to the housing within the sliding groove. The top end of the push rod is connected to the housing via the first spring located within the sliding groove. One end of the extension tube is hinged to the middle of the push rod via a pin. One end of the connecting rod is slidably connected to the extension tube within the other end of the extension tube, and the other end of the connecting rod is slidably connected to the connecting tube within the connecting tube. Both ends of the rotating shaft are fixedly connected to the inner wall of the housing, and the middle of the connecting rod is rotatably connected to the rotating shaft. The connecting rod is connected to the inner wall of the connecting tube via the second spring located within the connecting tube. The end of the connecting tube away from the push rod is hinged to the push ring via a pin.

[0010] The limiting post is equipped with an ink tank, and the top of the limiting post is equipped with an ink filling hole that is connected to the ink tank and the mounting hole of the housing. The bottom of the limiting post is equipped with an ink outlet hole that is connected to the ink tank. The ink filling assembly includes a bracket and an ink plug. One end of the bracket is fixedly connected to the fixing post, and the other end of the bracket is fixedly connected to the bottom end of the ink plug. The top end of the ink plug is located inside the ink outlet hole and contacts the limiting post.

[0011] The ink stopper is conical, and the shape of the ink outlet corresponds to the shape of the ink stopper.

[0012] The limiting post is provided with a plurality of force-equalizing locks, which are evenly distributed circumferentially on the outer wall of the limiting post along the axis of the limiting post. Each force-equalizing lock includes a spherical lock head and a third spring. The outer wall of the limiting post is provided with a lock core groove, and the inner wall of the push ring is provided with a lock head groove. One end of the spherical lock head is located in the lock core groove and is slidably connected to the limiting post, while the other end of the spherical lock head is located in the lock head groove and is in contact with the push ring. The spherical lock head is connected to the inner wall of the lock core groove through the third spring located in the lock core groove.

[0013] The housing is equipped with an air pipe, one end of which is connected to the housing and the other end of which is connected to the limiting post. The sliding groove, the air pipe, and the ink tank are connected in series.

[0014] The seal is detachably and fixedly connected to the fixing post.

[0015] Compared with the prior art, this utility model has the following beneficial effects: The positioning ring and the force-equalizing lock prevent the tilted stamp from contacting the paper during wrist rotation. The circumferentially distributed force-equalizing pressing component ensures uniform force when the stamp is pressed vertically, avoiding uneven force on the stamp caused by wrist rotation, which can lead to blurry or uneven stamping, thus improving stamping efficiency. Furthermore, the ink tank and ink outlet are installed inside the fixed column, and a bracket and ink plug are installed on the fixed column, allowing the stamping action to trigger ink replenishment synchronously. This extends the number of stamps after a single ink refill and reduces refilling time, ensuring the ink tank always contains ink. This avoids the traditional situation where the stamp needs to be left to diffuse evenly after refilling, further improving refilling efficiency. Attached Figure Description

[0029] like Figure 3 , Figure 4 and Figure 7As shown, the limiting post 5 is provided with an ink tank 17, and the top of the limiting post 5 is provided with an ink filling hole 18, which is connected to the ink tank 17 and the mounting hole of the housing 1. The bottom of the limiting post 5 is provided with an ink outlet hole 19, which is connected to the ink tank 17. The ink filling assembly includes a bracket 20 and an ink plug 21.

[0030] like Figure 7 As shown, the ink stopper 21 is conical, and the shape of the ink outlet 19 corresponds to the shape of the ink stopper 21.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the limiting post 5 is provided with several force equalizing locks. The force equalizing locks are evenly distributed circumferentially on the outer wall of the limiting post 5 along the axis of the limiting post 5. Each force equalizing lock includes a spherical lock head 22 and a third spring 23. The outer wall of the limiting post 5 is provided with a lock core groove 24, and the inner wall of the push ring 7 is provided with a lock head groove 25.

[0032] like Figure 2 and Figure 6 As shown, the housing 1 is provided with an air pipe 26. One end of the air pipe 26 is connected to the housing 1, and the other end of the air pipe 26 is connected to the limiting post 5. The sliding groove 16, the air pipe 26 and the ink tank 17 are connected.

[0033] like Figure 2 As shown, the seal 2 is detachably fixed to the fixing post 8.

[0034] The work process is as follows:

[0035] S1, In use, the user opens the compartment cover 2, holds the handle 3, and uses the positioning ring 6 to determine the position of the paper to be stamped. When the wrist is rotated to stamp, the positioning ring 6 partially contacts the paper and presses down. The push rod 9 connected to the positioning ring 6 cannot slide at the same time. At this time, the third spring 23 compresses the ball lock head 22 in the lock core groove 24 and locks it in the lock head groove 25. Since each equal force lock cannot be subjected to the compressive force at the same time, they cannot be unlocked at the same time. The push ring 7 is in a stationary state. When the bottom surface of the positioning ring 6 fully contacts the paper, the positioning ring 6 drives the push rod 9 to compress the first spring 13 and slides upward relative to the housing 1. The extension tube 15 drives one end of the connecting rod 10 to slide simultaneously. The connecting rod 10 rotates around the pivot 12, and the other end of the connecting rod 10 slides inside the connecting tube 11. Through the cooperation of the connecting rod 10 and the second spring 14, the connecting tube 11 is pushed to squeeze the pushing ring 7. Due to the circumferential distribution of multiple force-equalizing pressing components, the synchronous squeezing makes the horizontal component force of the pushing ring 7 balanced. The pushing ring 7 is subjected to the downward component force and begins to slide vertically downward along the outer wall of the limiting post 5. At this time, each force-equalizing lock is simultaneously squeezed by the pushing ring 7 and unlocked. The pushing ring 7 causes the fixed post 8 to slide down synchronously and evenly to push the stamp 2 to stamp. This avoids the uneven force on the stamp 2 caused by the wrist rotation when stamping, which leads to skewing and blurry or uneven stamping. This improves the stamping efficiency.

[0036] S2, during the downward pressing process, the fixed column 8 and the bracket 20 slide down synchronously, causing the ink stopper 21 to slide down and leave the ink outlet hole 19 at the bottom of the limiting column 5. The gas in the sliding groove 16 enters the ink tank 17 through the air pipe 26. The ink in the ink tank 17 flows into the stamp 2, which prolongs the number of stamps after a single ink filling and reduces the ink filling time. It always keeps the ink tank 17 with ink, avoiding the situation where the stamp 2 needs to be left to stand and wait for the ink to spread evenly after a single ink filling, thus improving the ink filling efficiency.

[0037] The stamp 2 is detachably fixed to the fixing post 8, which makes it easy to replace the stamp 2 or add ink to the stamp 2 separately. The handle 3 is detachably fixed to the housing 1, which makes it easy to add ink or clean it through the ink filling hole 18 after disassembly.

[0038] The parts of this utility model not described in detail are prior art. Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution.
