Description

Technical Field

[0001] The utility model relates to the technical field of official seals, in particular to an official seal with a self-locking function. Background Art

[0002] The existing official seal is composed of an outer shell carrier and an internal printing head. However, when it is used, it does not have a self-locking structure. The official seal may cause an accident without knowing it, causing damage to the internal printing head. For example, a Chinese patent discloses a "multifunctional official seal" with an application number of "201620121186.0". This device includes an installation cavity, an installation groove and an official seal body. The installation groove is arranged above the installation cavity and is connected to the installation cavity. The official seal body is arranged in the installation cavity. A connecting rod is connected above the official seal body. A pressure plate is arranged above the connecting rod. The pressure plate is fixedly connected to the installation groove through a tension spring. A pressure block and a pressure spring are arranged in the installation groove. The pressure spring is arranged between the pressure plate and the pressure block. A pressure rod and a handle are arranged above the pressure block. It has a simple structure, low manufacturing cost and easy use. However, when it is used, it does not have a self-locking structure. The official seal may cause an accident without knowing it, causing damage to the internal official seal body. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art and provides an official seal with a self-locking function. By turning a knob, the limit column of the slot can be moved so that the baffle is located on the top of the limit plate, so that the official seal cannot be pressed. When sealing, the seal cover is directly pressed into the slot, and the baffle will move backward to squeeze the elastic member until the slot is located at the card block position. The card block is pushed into the slot by the elastic member to complete the self-locking of the seal cover. Through the double locking of two positions, misoperation can be prevented. After being locked, the official seal cannot be pressed and the seal cover cannot be directly removed, which avoids the wrong seal or the wrong position due to misoperation, ensuring the accuracy and effectiveness of the use of the seal, and the self-locking can be completed by pressing the seal cover into the slot, eliminating extra operating steps and improving work efficiency.
