Abstract
Description
Technical Field
[0001] This utility model relates to the field of alarm device technology, and specifically to an alarm device. Background Technology
[0002] An alarm is a device that issues alarm signals. It is used to issue warnings, alerts, and all-clear signals. Many factories, such as chemical plants, have alarm systems installed. In order to better respond to emergencies, alarms are a crucial part of chemical safety management.
[0003] For example, Chinese utility model patent with publication number CN221081719U discloses an alarm device. This solution uses components such as a fixing base and a blocking block to allow staff to expose an appropriate number of inlet ports to the outside and block unused inlet ports when monitoring network security in real time. This prevents cold air from entering the protective housing through unused inlet ports and causing condensation, thus ensuring the stable operation of the alarm module.
[0004] The aforementioned solution achieves the blocking of unused inlet ports through the structure described above. However, the aforementioned solution still has shortcomings. The blocking mechanism in the aforementioned solution is installed inside the housing. The housing needs to be opened every time it is blocked or opened for use. In addition, the internal space of the housing is limited. The operator needs to enter the housing with their hands while observing the operation. During this process, the operation is relatively difficult and inconvenient for normal use. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides an alarm device, including a housing and an alarm light mounted on the housing. One side of the housing has multiple wiring holes. The device also includes a sealing mechanism, with multiple sealing mechanisms inserted into the wiring holes via connectors. The connectors are fixed to a main body, and a wire guard is fixed to the inner wall of the main body. The wire guard has multiple elongated holes distributed circumferentially on it, and the wire guard is made of rubber. The sealing mechanism is used to seal the wiring holes on the housing.
[0006] Furthermore, a second fixing plate and a first fixing plate are fixed on the main body. The second fixing plate and the first fixing plate are arranged symmetrically. A sealing cover is rotatably connected to the second fixing plate. The sealing cover covers the main body and can rotate freely.
[0007] Furthermore, a limiting member is fixed on one side of the main body, and the sealing cover can be connected to the limiting member.
[0008] Furthermore, a snap-fit groove is provided on the first fixing plate, and a snap-fit component adapted to the snap-fit groove is provided on the sealing cover.
[0009] Furthermore, a fixing cylinder is fixed on the sealing cover, the fixing cylinder has an inner cavity, and a circular hole is opened on the sealing cover, and the snap-fit member can slide in the circular hole and the inner cavity.
[0010] Furthermore, a spring is installed in the inner cavity of the fixed cylinder, and the spring is connected to the snap-fit member and the inner wall of the fixed cylinder respectively. The snap-fit member can be moved by the elastic force of the spring.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] By setting up a blocking mechanism, the blocking mechanism seals the cable hole from the outside, which facilitates installation and operation. The blocking mechanism is also equipped with a cable protection plate to protect the cable from scratches, which can protect the cable connected to the alarm device. Furthermore, the blocking mechanism on the alarm device is designed to be separate from the housing, which makes it easy to replace in case of damage, thus improving its practicality.

[0020] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0021] like Figures 1-5 This embodiment provides an alarm device, including a housing 1 and an alarm light 2 mounted on the housing 1. One side of the housing 1 has multiple wiring holes. It also includes a sealing mechanism 3, which is inserted into the wiring holes via connectors 302. The connectors 302 are fixed to the main body 301 and are made of rubber for easy insertion. They have multiple anti-slip grooves and are tapered. A wire protection plate 308 is fixed to the inner wall of the main body 301. The wire protection plate 308 has multiple elongated holes distributed along the circumference. The wire protection plate 308 is made of rubber and can protect the wiring, preventing wear caused by friction between the wiring and the housing. This wire protection plate 308 is commonly found on office desks in daily life; it is soft and has a dust-proof function. The sealing mechanism 3 is used to seal the wiring holes on the housing 1.
[0022] In this embodiment, as Figure 2 and Figure 3 As shown, a second fixing plate 304 and a first fixing plate 303 are fixed on the main body 301. The second fixing plate 304 and the first fixing plate 303 are symmetrically arranged. A sealing cover 305 is rotatably connected to the second fixing plate 304. The sealing cover 305 covers the main body 301 and can rotate freely. A limiting member 306 is fixed on one side of the main body 301. The limiting member 306 has a limiting function and can assist in rotating the sealing cover 305 to close the main body 301. The sealing cover 305 can be connected to the limiting member 306. When a certain cable hole is idle, the sealing cover 305 can be rotated until it covers the main body 301 and connects with the limiting member 306 to seal the hole and prevent dust or air from entering and condensing, which would affect the normal use of the alarm device.
[0023] In this embodiment, as Figure 4 and Figure 5As shown, a snap-fit groove 309 is provided on the first fixing plate 303. A snap-fit member 310 adapted to the snap-fit groove 309 is provided on the sealing cover 305. A fixing cylinder 307 is fixed on the sealing cover 305. The fixing cylinder 307 has an inner cavity. A round hole is provided on the sealing cover 305. The snap-fit member 310 can slide in the round hole and the inner cavity. A spring 311 is placed in the inner cavity of the fixing cylinder 307. The spring 311 is connected to the snap-fit member 310 and the inner wall of the fixing cylinder 307 respectively. The snap-fit member 310 can move by the elastic force of the spring 311. When the sealing cover 305 is rotated by pinching the fixing cylinder 307, the snap-fit member 310 is pressed on the first fixing plate 303, which will compress the spring 311 and move into the fixing cylinder 307. When the snap-fit member 310 is embedded in the snap-fit groove 309, the snap-fit member 310 is pushed by the spring 311 to achieve stable snap-fit sealing, which is convenient to use.
[0024] The implementation principle of an alarm device according to an embodiment of this application is as follows: When in use, the sealing cover 305 can be opened to connect the line. The line is passed through the protective strip 308, which is made of rubber and can protect the line. The sealing cover 305 is rotated by pinching the fixing cylinder 307. The snap-fit 310 is pressed against the first fixing plate 303, which will compress the spring 311 and move into the fixing cylinder 307. When the snap-fit 310 is embedded in the snap-fit groove 309, the snap-fit 310 is pushed by the spring 311 to achieve stable snap-fit and closure, which is convenient to use.
