Description

Technical Field

[0001] The utility model belongs to the field of alarms, and in particular relates to an alarm with a quick-disassembly structure. Background Art

[0002] Alarms are divided into mechanical alarms and electronic alarms. With the advancement of technology, mechanical alarms are increasingly being replaced by advanced electronic alarms, which are often used in areas such as system failures, security precautions, transportation, medical rescue, emergency rescue, induction detection, etc., and are inseparable from social production. For example: door magnetic sensors and gas induction alarms. However, a dust cover is installed on the outside of the lamp body of the existing alarm. The existing dust cover is fixed by screws. After a period of time, the screws are prone to slipping and rusting, which makes disassembly and maintenance very troublesome.

[0003] Therefore, an alarm with a quick-release structure is proposed to solve the above-mentioned drawbacks. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an alarm with a quick-disassembly structure.

[0008] Optionally, a second annular groove is provided at the bottom of the base, and the cross-section of the second annular groove is T-shaped. The second annular groove is connected to the first annular groove, and the internal rotation of the first annular groove is cooperated with the first annular column, which facilitates the first annular column to rotate inside the base through the first annular groove, reduces the problem of the first annular column rotating out of the first annular groove, and improves the stability of the first annular column during rotation. The cross-section of the first annular column is T-shaped, and the first annular plate is mounted on the first annular column. A first spring and a second spring sleeved on the circumferential side of the first spring are installed inside the first annular groove, which facilitates the installation of the first spring inside the first annular groove and the installation of the second spring inside the first annular groove. The first annular plate is located between the first spring and the second spring.

[0009] Optionally, one end of the first spring contacts one end of the second annular plate, and one end of the second spring contacts one end of the second annular plate, so that the second annular plate can slide out from the inside of the first annular groove under the elastic action of the first spring and the second spring. A third annular groove is provided at one end of the second annular plate, and the cross-section of the third annular groove is T-shaped. A second annular column is installed at the opening of the cover, so that the second annular column can be installed on the opening of the cover. The second annular column is rotatably engaged with the inside of the third annular groove, so that the second annular column can rotate inside the second annular plate through the third annular groove, thereby reducing the problem of the second annular column rotating out of the inside of the third annular groove and improving the stability of the second annular column during rotation. The cross-section of the second annular column is T-shaped. An annular groove is provided on one side of the second annular plate, and the first annular plate is located inside the annular groove. A plurality of positioning holes are provided on one side of the base, and positioning pins are installed inside the positioning holes, so that the positioning pins can be placed inside the base through the positioning holes.

[0010] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0011] The second annular plate is arranged so that the second annular plate can be rotated in and out of the first annular groove under the action of the user, so as to fix and release the cover through the second annular plate. On the one hand, it makes the process of disassembling and assembling the cover more convenient, and on the other hand, it makes the process of inspecting and repairing the alarm body more convenient.
