Description

Technical Field

[0001] The utility model relates to the technical field of seals, in particular to a fixing device for a photosensitive seal. Background Art

[0002] Seals are stationery used to print on documents to indicate identification or signature. They are widely used in various industries such as banks, enterprises, and schools. As the most direct and effective legal certificate, the standardized use and safekeeping of seals are of great significance in all walks of life. In daily life, many occasions require stamp verification, from banks and administrative offices to parks, railway stations, airports, park entrances, etc., where the face of the ticket needs to be stamped to confirm.

[0003] There are many types of seals on sale in China, and there is no unified standard for the shape and size of the shell. When loading into a portable seal control instrument, the seal face needs to be turned over when stamping, and the internal space of the seal control instrument is limited, so the seal cannot be loaded as a whole, and the seal handle can only be removed. Due to the special structure, many types and large differences of photosensitive seals, it is difficult to install them in a portable seal control instrument, and there is no unified method. The usual practice is to design a metal shell according to the size of the photosensitive seal, put the photosensitive seal pad in it, and build a sponge pad inside, but it becomes more difficult to add ink, because the seal box needs to be taken out to add ink, so it is time-consuming and laborious. At present, the common practice in the industry is to open a refueling hole on the back of the seal box and refuel directly to the sponge pad; or add an ink distribution part between the sponge pad and the shell to increase the space for ink flow. This method is also the structure adopted by most photosensitive seals when designing. Although this design can solve the problem of refueling without removing the stamp box, the ink can only be added to the area directly below the refueling hole. The fluidity of the ink is poor, resulting in only a part of the area being actually refueled, and the entire area cannot be refueled. It will also cause the problem of one part of the stamp surface being dark in color (usually the middle area) and another part being light in color (usually the edge area of ​​the stamp).

[0004] In view of the above problems, a fixing device for a photosensitive stamp is designed specifically. Utility Model Content

[0005] The utility model is aimed at the above-mentioned problems and specifically designs a fixing device for a photosensitive stamp, which solves the problems of uneven stamp color depth caused by uneven absorption of a sponge pad, the overflow of printing oil from the seal shell gap or the edge of the photosensitive stamp pad due to the printing oil not being absorbed into the sponge pad, and the problem of having to take out the stamp to refuel the stamp box in a portable printing control instrument.

[0006] To achieve the above-mentioned purpose, the utility model provides a fixing device for a photosensitive seal, comprising: a seal ink top cover and a fixing ring, a seal ink distribution part is arranged below the seal ink top cover, a sponge pad is arranged below the seal ink distribution part, a photosensitive seal pad is arranged below the sponge pad, the middle of the seal ink distribution part is arranged in a cone shape, a plurality of guide grooves are arranged from the apex to the bottom of the cone and are evenly distributed, a plurality of small oil injection holes are arranged in the guide groove, and a plurality of triangular structures are extended from the edge of the seal ink distribution part to the center.

[0007] The above method increases the fluidity of the ink and enhances the structural strength of the ink distribution portion.

[0008] Preferably, a large oil filling hole is arranged at the central portion of the ink top cover, and a recessed structure is arranged between the middle portion of the ink top cover and the ink distribution portion.

[0009] The above method increases the flow space of the printing ink, and increases the speed and area of ​​the printing ink flow.

[0010] Preferably, the ink top cover is knurled, and the ink top cover and the fixing ring are fastened with internal and external threads, and the ink distribution part, the sponge pad, and the photosensitive seal pad are clamped.

[0011] Preferably, the sponge pad has the same diameter as the ink dispensing portion and is cylindrical.

[0012] Preferably, the photosensitive seal pad is provided with a convex groove, and the photosensitive seal pad is suitable for assembly with a fixing ring.

[0013] Preferably, the guide groove is provided with two circles of small oil injection holes and a central oil injection hole is provided at the center, and the diameter of the small oil injection hole increases as it is closer to the bottom of the cone.

[0014] The printing ink is evenly distributed to every area of ​​the sponge pad in the above manner.

[0015] In summary, the utility model has the following advantages and beneficial technical effects:

[0016] In this device, after the printing ink is filled in from the printing ink top cover, it can be evenly moistened to every area of ​​the sponge pad through the printing ink distribution part, which effectively solves the problem of uneven stamp color depth caused by uneven absorption of the sponge pad, the problem of printing oil overflowing from the gap of the stamp shell or the edge of the photosensitive stamp pad because the printing oil is not absorbed into the sponge pad, and the problem of having to take out the stamp to refill the stamp box in the portable printing control instrument.

[0023] The following is combined with Figure 1-Figure 4 The utility model is further described in detail:

[0024] like Figure 1 As shown, it includes: a printing ink top cover 1 and a fixing ring 5, the printing ink top cover 1 is placed above the printing ink distribution part 2, the printing ink distribution part 2 is placed on the sponge pad 3, the sponge pad 3 is placed on the photosensitive seal pad 4, the middle of the printing ink distribution part 2 is conical, 12 guide grooves 21 are opened from the vertex to the bottom of the cone and are evenly distributed, there are multiple small oil filling holes 22 in the guide grooves 21, and 6 triangular structures 24 extend from the edge of the printing ink distribution part 2 to the center.

[0025] The ink distribution part 2 is cone-shaped in the middle, the purpose of which is to increase the fluidity of the ink by the inclination angle, so as to promote the uniform flow of the ink from the center to every direction; 12 guide grooves 21 are provided from the apex to the bottom of the cone, which further reduces the long-term inability of the ink to enter the oil filling hole due to the large surface tension of the ink; 6 triangular structures 24 extend from the edge of the ink distribution part 2 to the center, the purpose of which is to enhance the structural strength. The bottom of the cone is thinner, and the force of stamping will be transmitted to the ink distribution part 2. If the central area of ​​the ink distribution part 2 is not supported, the support frame will cause long-term structural fatigue and cause the middle part to sag, which will lead to insufficient support of the photosensitive stamp pad 4 and unclear stamping.

[0026] like Figure 2 As shown, the central portion of the ink cap 1 is a large oil filling hole 11 of 7 mm, and a recessed structure 6 is provided between the middle portion of the ink cap 1 and the ink distributing portion 2 .

[0027] The purpose of the concave structure 6 is to increase the space for the ink to flow. Since the ink has a high viscosity and a large surface tension, it has a poor flow ability in a small space. Increasing the flow space increases the speed and area of ​​the ink flow.

[0028] The ink top cover 1 is knurled, and the ink top cover 1 and the fixing ring 5 are fastened with internal and external threads, and the ink distribution part 2, the sponge pad 3, and the photosensitive seal pad 4 are clamped.

[0029] The sponge pad 3 has the same diameter as the ink distributing portion 2 and is cylindrical.

[0030] The photosensitive chapter pad 4 has a convex groove, and the photosensitive chapter pad 4 is suitable for assembly with the fixing ring 5.

[0031] like Figure 3 As shown, the guide groove 21 has two circles of small oil injection holes 22 and a central oil injection hole 23 at the center. The diameter of the small oil injection hole 22 increases as it approaches the bottom of the cone.

[0032] The small oil filling hole 22 arranged in the center of the guide groove 21 has a diameter of 2mm. With the central oil filling hole 23 at the center of the guide groove 21 as the center, two circles of small oil filling holes 22 are radiated outward, with 12 holes in each circle. The spacing of each circle of oil filling holes is obtained according to the area printed with ink after an oil filling hole is filled with ink, and the closer to the bottom of the cone, the larger the oil filling hole is, in order to ensure that no matter how much ink is added at a single time, the ink can be evenly distributed to every area of ​​the sponge pad. The diameter of the oil filling holes in the first circle is 1.7mm, and the diameter of the oil filling holes in the outermost circle is 2mm, and a guide arc angle is provided.

[0033] The working principle of the fixing device of the photosensitive seal of the utility model is:

[0034] In this device, first, the ink is injected into the large oil filling hole 11, and the ink drips into the ink distribution part 2. The ink distribution part 2 increases the fluidity of the ink by the tilt angle, so that the ink flows evenly from the center along the guide groove 21 to each direction and drips to the sponge pad 3; the ink on the sponge pad 3 will infiltrate the photosensitive seal pad 4. From the top to the bottom of the cone, multiple guide grooves 21 are designed, which further reduce the long-term inability of the ink to enter the oil filling hole due to the large surface tension of the ink, and greatly increase the speed of the ink entering the sponge pad 3; the edge of the ink distribution part 2 extends to the center with multiple triangular structures 24, the purpose is to strengthen the structural strength. The bottom of the cone is thin, and the force of stamping will be transmitted to the ink distribution part 2. If the central area of ​​the ink distribution part 2 is not supported, it will cause the support frame to fatigue for a long time and cause the middle part to be concave, which will lead to insufficient support of the photosensitive seal pad 4 and unclear stamping.

[0035] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
