Description

Technical Field

[0001] The utility model relates to a penetration seal, in particular to a cross-positioning seal. Background Art

[0002] At present, penetration stamps have gradually replaced traditional stamps and are widely used in office stamping work as common items; this is because penetration stamps come with their own ink, are easy to use and can be repeatedly refilled with ink, making the use of penetration stamps simple and their service life long.

[0003] However, existing penetration seals generally have the problem of being inconvenient to install and disassemble. For this reason, the industry has been continuously making technical improvements. For example, the National Intellectual Property Administration published a utility model patent with the authorization announcement number CN208452599U on February 1, 2019. The seal device disclosed in the application includes a buckle plate fixed at the lower end of the column core and a bucket body connected to the buckle plate. The buckle plate has a buckle position formed in the middle part, and the bucket body has a buckle head formed in the middle part corresponding to the buckle position. The buckle head is inserted in the buckle position to realize the buckle connection between the buckle plate and the bucket body. Such a structure realizes an improvement over the traditional one-piece seal that is not easy to disassemble, and the seal bucket body and the seal column body are separated by buckle plug-in connection. However, this structure has a problem in actual use. That is, when it is plugged in, since the buckle is a circular setting with no direction limit, it is easy for the direction required for stamping to be inconsistent with the required direction. In addition, after long-term use and multiple disassembly, the buckle head is prone to shaking in the buckle position, resulting in unstable stamping and blurred required stamping pattern.

[0004] Therefore, there is a need to provide a permeable stamp which is easy to disassemble, has a certain stamping direction, and is not prone to shaking. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a cross-positioned seal, which solves the problems that the stamping direction of the existing penetration seal is difficult to determine and is prone to shaking.

[0007] The limit clamping end arranged at the lower end of the seal bucket upper cover includes a cross clamping joint, and the limit clamping device arranged in the seal bucket body includes a cross clamping groove. When the cross clamping joint is clamped with the cross clamping groove, the seal bucket body is fixedly connected under the seal bucket upper cover.

[0008] The cross clamping joint includes a clamping portion and a limiting portion, and the clamping portion and the limiting portion are in a cross-cross structure; the clamping portion is a long strip-shaped protrusion, and its cross-section is T-shaped, and the limiting portion is a rectangular long strip-shaped protrusion, and a chamfer is provided at one end away from the seal bucket cover; the cross clamping groove is correspondingly provided with a groove body structure matching the clamping portion and the limiting portion relative to the clamping portion and the limiting portion.

[0010] Based on the above-mentioned cross-limiting seal, further, the card plate is connected to the seal shell, and a card plate slot is provided in the seal shell. When the card plate slot in the seal shell is connected to the card plate, the seal shell wraps the seal column, the seal bucket cover and the seal bucket body, and a stamping opening is opened at the lower end of the seal shell.

[0011] Based on the above-mentioned cross-limiting seal, further, two snap-in openings are provided at the outer edges of the seal bucket upper cover and the bucket body wall, and when the cross snap-in joint is snapped with the cross snap-in groove, the snap-in openings on the seal bucket upper cover and the bucket body wall are aligned.

[0012] Based on the above cross-limiting seal, further, a connecting portion is provided on the side wall of the seal shell, and when the seal shell is clamped on the outside of the seal column, the connecting portion passes through the clamping port.

[0013] Based on the above-mentioned cross-limiting seal, further, the seal bucket is a cylindrical structure with openings at both ends and a circular side wall as a bucket wall, and a limiting clamping device and a partition plate are sequentially arranged inside from top to bottom, and the limiting clamping device and the partition plate are an integrated structure.

[0014] Based on the above cross-positioned seal, further, the cross clamping joint is arranged at the center of the upper cover of the seal bucket, and the cross clamping groove is arranged at the center of the partition plate.

[0015] Based on the above cross-positioned seal, further, the seal column, the seal bucket upper cover and the seal bucket body are all made of hard polyvinyl chloride plastic.

[0016] Beneficial effects:

[0017] (1) The cross-limiting seal disclosed by the utility model has a cross-clamping joint at the lower end of the seal bucket cover, and a cross-clamping groove at the lower end of the seal bucket cover. When the cross-clamping joint is clamped with the cross-clamping groove, the seal bucket body is fixedly connected to the lower part of the seal bucket cover. This connection method obviously makes the seal easy to install and disassemble. On this basis, the cross-clamping joint includes a clamping part and a limiting part of different shapes, which respectively realize the two functions of clamping and limiting, so that the seal has the characteristics of limiting and clamping at the same time. When using it, the stamping direction can be easily determined every time, and there will be no problem of confusion in the stamping direction. In addition, because the cross-clamping joint and the cross-clamping groove are a cross-cross structure, it is ensured that when the user uses the seal, it is not easy to cause the stamp to be blurred due to the shaking of the seal.

[0018] (2) In the cross-limiting seal disclosed by the utility model, the clamping part is a T-shaped long strip protrusion, the limiting part is a pointed long strip protrusion, and the cross-clamping groove is provided with a matching groove structure corresponding to the clamping part and the limiting part. When installing the seal, the installation direction can be easily determined, and the problem of incorrect installation of the clamping part and the limiting part will not occur.

[0019] (3) The cross-limiting seal disclosed by the utility model has vertical clamping plates evenly distributed on the side walls of the seal column core, and a clamping plate groove is arranged in the seal shell; two clamping holes are provided at the outer edges of the seal bucket upper cover and the bucket body wall. When the seal shell is clamped to the outside of the seal column, the connecting part arranged on its inner wall passes through the clamping hole to fix the seal column, the seal bucket upper cover and the seal bucket body in the seal shell, which makes the overall structure of the seal more stable, and the connecting part passes through the clamping hole to play an auxiliary limiting role, so that the seal bucket body is better fixed when in use and will not shake.
