Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilization technology, and in particular to a suspension installation structure for a smoke alarm. Background Technology

[0002] Smoke detectors are essential fire prevention devices, capable of detecting smoke and issuing alarms promptly, effectively mitigating problems such as delayed fire detection and missed opportunities for optimal firefighting. With technological advancements, smoke detectors utilizing LoRa technology offer advantages such as long range, low power consumption, and strong anti-interference capabilities, enabling them to provide audible and visual alarms and send information to mobile phones when smoke concentrations exceed safe levels in the home.

[0003] Currently, smoke detectors are usually installed on the top of the wall. However, the floor height of some buildings is relatively large, which makes it difficult to install smoke detectors too high and meet the appropriate monitoring height requirements. Therefore, there is a need for a smoke detector suspension installation structure that can flexibly adjust the installation height to adapt to different floor heights and monitoring needs.

[0004] To address the aforementioned problems, this utility model document proposes a suspension mounting structure for a smoke alarm. Utility Model Content

[0005] This utility model provides a hanging installation structure for a smoke alarm, which solves the shortcomings of the prior art where smoke alarms are usually installed on the top of the wall, but the floor height is large in some buildings, resulting in the smoke alarm being installed too high and making it difficult to meet the appropriate monitoring height requirements.

[0006] This utility model provides the following technical solution:

[0007] A suspension mounting structure for a smoke detector includes:

[0008] The smoke alarm body has a detachable maintenance plate at the top opening of the shell. Above the maintenance plate is a mounting plate that connects to the top of the wall. A support tube is welded and fixed to the center of the bottom of the mounting plate. An adjustment tube is slidably installed in the cavity at the bottom end of the support tube. The bottom end of the adjustment tube is glued and fixed to the center of the top of the maintenance plate.

[0009] In one possible design, the inspection plate has two symmetrically arranged first reserved holes, and a corresponding first screw bolt is inserted through the first reserved hole.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] In one embodiment:

[0031] Please refer to Figure 1-4 An installation structure includes a smoke detector body 1, an inspection plate 2, a mounting plate 8, a support pipe 12, an adjustment pipe 14, etc.

[0032] The smoke alarm body 1 is a conventional photoelectric smoke alarm structure. It contains a light-emitting diode (LED) and a photosensitive sensor. Under normal operating conditions, the LED emits light, which travels in a straight line inside the alarm. The photosensitive sensor does not receive the light. When smoke enters the alarm, the smoke particles scatter the light, causing some of it to reach the photosensitive sensor. Upon receiving the light, the sensor's impedance changes, generating a photocurrent. When the photocurrent reaches a certain level, the internal circuitry triggers an audible and visual alarm. The smoke alarm body 1 has a shell opening at its top. A maintenance plate 2 is detachably mounted at this opening. The maintenance plate 2 has two symmetrically arranged first pre-drilled holes 4, each with a corresponding first bolt 3. A threaded groove 5 is located on the top of the smoke alarm body 1 corresponding to the first pre-drilled hole 4. The end of the first bolt 3 is threaded into the threaded groove 5, thus enabling a detachable connection between the maintenance plate 2 and the smoke alarm body 1.

[0033] Mounting plate 8 is used to connect to the top of the wall. It has two symmetrical second reserved holes 10. During installation, mark the corresponding position on the top of the wall according to the second reserved holes 10 on the mounting plate 8. Then, use expansion bolts 9 to pass through the second reserved holes 10 and drive them into the pre-marked position on the top of the wall. Then, tighten them with the matching nuts 11 to firmly fix the mounting plate 8 to the top of the wall.

[0034] A support tube 12 is welded and fixed to the center of the bottom of the mounting plate 8. The bottom end of the support tube 12 has a cavity 13. The adjusting tube 14 is slidably disposed in the cavity 13. The bottom end of the adjusting tube 14 is glued and fixed to the center of the top of the inspection plate 2. To lock the extension length of the adjusting tube 14, a threaded hole 15 is provided on the side wall of the support tube 12. A second screw 16 is threaded into the threaded hole 15. When the extension length of the adjusting tube 14 is adjusted properly, the second screw 16 is screwed into the threaded hole 15 so that the end of the second screw 16 is tightly against the side wall of the adjusting tube 14, thereby locking the extension length of the adjusting tube 14. To facilitate the connection between the adjusting tube 14 and the inspection plate 2, a double-sided adhesive plate 17 is pasted on the flat surface of the bottom end of the adjusting tube 14. An annular adhesive seat 18 is fixedly disposed in the center of the top of the inspection plate 2. The other adhesive surface of the double-sided adhesive plate 17 is glued and fixed to the bottom of the inner wall of the annular adhesive seat 18.

[0035] In the actual installation process, first determine the installation location of the smoke alarm, which is generally the top of the wall. According to the above method, fix the mounting plate 8 to the top of the wall with expansion bolts 9 and nuts 11. Then, insert the adjusting tube 14 into the cavity 13 at the bottom of the support tube 12. Adjust the extension length of the adjusting tube 14 according to the floor height and monitoring height requirements. After the adjustment is appropriate, tighten the second screw 16 to lock the extension length of the adjusting tube 14. After inserting the battery into the smoke alarm body 1, pass the first screw 3 through the first reserved hole 4 and thread it with the threaded groove 5. Install the maintenance plate 2 detachably at the shell opening at the top of the smoke alarm body 1. Finally, stick the double-sided adhesive plate 17 on the flat surface at the bottom of the adjusting tube 14, and then stick the other side of the double-sided adhesive plate 17 to the bottom of the inner wall of the annular adhesive seat 18 to fix it, so that the adjusting tube 14 is connected to the center of the top of the maintenance plate 2, and the entire smoke alarm hanging installation is completed.

[0036] After installation, test the smoke detector to check its various functions, such as audible and visual alarms and information transmission. Ensure the smoke detector can accurately detect smoke and issue an alarm promptly. During daily use, when maintenance or battery replacement is required, simply unscrew the first bolt 3 and remove the access plate 2 from the smoke detector body 1 to access its internal components. After maintenance, reinstall the access plate 2 onto the smoke detector body 1 following the same steps.

[0037] This application can be used for the hanging installation of smoke detectors, and can also be used in other fields applicable to this application.
