The device consists of a controller, detector, signal cable, etc. The product has passed the inspection of the National Fire Electronic Product Inspection Center. The detection element in the detector adopts an imported special gas sensor, which has the advantages of high sensitivity, strong stability, long life and low power consumption.

[0003] An existing type of fire alarm detector that is easy to install and disassemble is inconvenient for staff to install inside the overall equipment, thus affecting the ease of operation when placing the fire alarm detector inside the equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fire detection alarm that is easy to assemble and disassemble quickly.

[0005] This utility model is achieved by the following technical solution: a fire detection alarm that is easy to assemble and disassemble quickly, including a fire detection alarm, a mounting frame 1 is inserted into the surface of the fire detection alarm, a screw rod 1 is threadedly connected to the inside of the mounting frame 1, a protective bracket is fixedly connected to the bottom of the mounting frame 1, a mounting frame 2 is fixedly connected to the bottom of the protective bracket, and a screw rod 2 is threadedly connected to the inside of the mounting frame 2.

[0006] The protective bracket has a sliding connection to a limiting support plate inside. The limiting support plate has a threaded connection to an installation screw inside. The installation screw has a threaded connection to a fixing support plate on its surface. The rear end of the protective bracket is fixedly connected to a rotating seat. The surface of the rotating seat is rotatably connected to a supporting vertical rod. The supporting vertical rod has a rotatably connected horizontal rod inside. The horizontal rod has a rotatably connected angle adjustment seat inside.

[0007] With the above technical solution, the mounting screw is used to connect the fixed support plate and the limiting support plate. By rotating the mounting screw, the distance between the limiting support plate and the fixed support plate can be adjusted, thereby realizing the clamping or loosening operation of the fire alarm detector, which facilitates the installation and disassembly of the alarm.

[0008] As a further improvement to the above solution, the number of mounting brackets and screws is set to two, and the two mounting brackets and screws are symmetrically distributed on the left and right sides with the protective bracket as the center.

[0009] With the above technical solution, when installing the fire alarm detector, first place the alarm in a suitable position inside the mounting frame one, insert the screw one into the threaded hole of the mounting frame one, rotate the screw one, and the screw one will gradually penetrate into the mounting frame one and the fire alarm detector under the action of the thread. As the screw one is screwed in, it will apply pressure to the fire alarm detector, and fix it tightly inside the mounting frame one.

[0010] As a further improvement to the above solution, the first screw extends through the first mounting frame and into the interior of the fire detection alarm, and the second screw extends through the second mounting frame and into the interior of the fire detection alarm.

[0011] Through the above technical solution, the protective bracket connects mounting frame one and mounting frame two through its own structure to form an integral support structure. During the installation process, the fire alarm detector is first placed in a suitable position between mounting frame one and mounting frame two. Then, screw two is inserted into the threaded hole of mounting frame two and screwed into the fire alarm detector. During the rotation, screw two works together with screw one to firmly fix the fire alarm detector in the installation structure formed by the protective bracket.

[0012] As a further improvement to the above solution, the number of limiting support plates is set to two, and the two limiting support plates are symmetrically distributed on the left and right sides with the protective bracket as the center. The inner wall of the limiting support plate is in contact with the surface of the fire detection alarm.

[0013] As a further improvement to the above solution, the number of mounting screws and fixing plates is set to two. The two mounting screws and fixing plates are symmetrically distributed on the left and right sides with the protective bracket as the center. The mounting screws extend through the fixing plates and into the interior of the limiting plate.

[0014] As a further improvement to the above solution, the supporting vertical rod is located at the rear end of the protective bracket, the angle adjustment seat is fixedly connected to the rear end of the protective bracket, and the number of the angle adjustment seats is set to two, with the two angle adjustment seats symmetrically distributed around the protective bracket.

[0015] As a further improvement to the above solution, the connecting crossbar is located at the rear end of the protective bracket, and the number of the supporting vertical bar and the connecting crossbar is set to two, with the two supporting vertical bars and the connecting crossbar symmetrically distributed around the protective bracket.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a mechanism where, when the angle of the fire alarm detector needs adjustment, an external force is applied to the supporting vertical rod, causing it to rotate around the rotating base. This rotation of the supporting vertical rod drives the connecting horizontal rod to move, which in turn transmits this motion to the angle adjustment seat. Based on the force transmitted from the connecting horizontal rod, the angle adjustment seat changes its relative position to the protective bracket or other components, thereby achieving angle adjustment of the fire alarm detector. This allows the fire alarm detector to accurately perform its detection work in different installation environments, such as walls of different heights and inclinations.

[0018] This invention involves placing a limiting support plate inside a protective bracket during the installation of a fire alarm detector, ensuring its inner wall contacts the surface of the fire alarm detector. An installation screw is then inserted through the threaded hole of the fixed support plate and screwed into the limiting support plate. By rotating the installation screw, the fixed support plate remains stationary, while the limiting support plate moves closer to or further away from the fixed support plate depending on the screw's direction. When the installation screw is tightened, the limiting support plate clamps the fire alarm detector, thus limiting and assisting in its fixation. Attached Figure Description

[0027] Example:

A protective bracket 4 is fixedly connected to the bottom of the mounting frame 2. A mounting frame 5 is fixedly connected to the bottom of the protective bracket 4. A screw 6 is threadedly connected to the inside of the mounting frame 5.

[0029] The protective bracket 4 has a sliding connection to a limiting support plate 7. The limiting support plate 7 has a threaded connection to a mounting screw 8. The mounting screw 8 has a threaded connection to a fixing support plate 9. The rear end of the protective bracket 4 is fixedly connected to a rotating seat 10. The surface of the rotating seat 10 is rotatably connected to a supporting vertical rod 11. The supporting vertical rod 11 has a rotatably connected connecting horizontal rod 12. The connecting horizontal rod 12 has a rotatably connected angle adjustment seat 13. When the angle of the fire alarm detector 1 needs to be adjusted, an external force is applied to the supporting vertical rod 11, causing it to rotate around the rotating seat 10. The rotation of the supporting vertical rod 11 will drive the connecting horizontal rod 12 to move. The connecting horizontal rod 12 transmits this movement to the angle adjustment seat 13. The angle adjustment seat 13 changes its relative position to the protective bracket 4 or other components according to the force transmitted from the connecting horizontal rod 12, thereby realizing the adjustment of the angle of the fire alarm detector 1. This allows the fire alarm detector 1 to accurately perform detection work in different installation environments, such as walls of different heights and inclinations.

[0030] The mounting screw 8 is used to connect the fixed support plate 9 and the limiting support plate 7. By rotating the mounting screw 8, the distance between the limiting support plate 7 and the fixed support plate 9 can be adjusted, thereby enabling the clamping or loosening operation of the fire alarm detector 1, which facilitates the installation and disassembly of the alarm.

[0031] The number of mounting brackets 12 and screws 13 is set to two, and the two mounting brackets 12 and screws 13 are symmetrically distributed on the left and right sides with the protective bracket 4 as the center.

[0032] When installing the fire alarm detector 1, first place the alarm in a suitable position inside the mounting frame 2, insert the screw 3 into the threaded hole of the mounting frame 2, and rotate the screw 3. Under the action of the thread, the screw 3 gradually penetrates into the mounting frame 2 and the fire alarm detector 1. As the screw 3 is screwed in, it will apply pressure to the fire alarm detector 1, and fix it tightly inside the mounting frame 2.

[0033] Screw 1 3 extends through mounting bracket 1 2 and into the interior of fire detector 1, and screw 2 6 extends through mounting bracket 2 5 and into the interior of fire detector 1.

[0034] The protective bracket 4 connects the mounting frame 1 2 and the mounting frame 2 5 through its own structure to form an integral support structure. During the installation process, the fire detector 1 is first placed in a suitable position between the mounting frame 1 2 and the mounting frame 2 5. Then, the screw 2 6 is inserted into the threaded hole of the mounting frame 2 5 and screwed into the fire detector 1. During the rotation, the screw 2 6 works together with the screw 1 3 to firmly fix the fire detector 1 in the installation structure formed by the protective bracket 4.

[0035] The number of limiting support plates 7 is set to two. The two limiting support plates 7 are symmetrically distributed on the left and right sides with the protective bracket 4 as the center. The inner wall of the limiting support plate 7 is in contact with the surface of the fire detection alarm 1.

[0036] The number of mounting screws 8 and fixing plates 9 is set to two. The two mounting screws 8 and fixing plates 9 are symmetrically distributed on the left and right sides with the protective bracket 4 as the center. The mounting screws 8 pass through the fixing plates 9 and extend into the interior of the limiting plate 7.

[0037] The supporting vertical rod 11 is located at the rear end of the protective bracket 4. The angle adjustment seat 13 is fixedly connected to the rear end of the protective bracket 4. The number of angle adjustment seats 13 is set to two, and the two angle adjustment seats 13 are symmetrically distributed with the protective bracket 4 as the center. When installing the fire detection alarm 1, the limiting support plate 7 is placed inside the protective bracket 4 so that its inner wall contacts the surface of the fire detection alarm 1. The installation screw 8 is inserted from the threaded hole of the fixed support plate 9 and screwed into the limiting support plate 7. By rotating the installation screw 8, the fixed support plate 9 remains stationary. The limiting support plate 7 will move closer to or further away from the fixed support plate 9 according to the screwing direction of the installation screw 8. When the installation screw 8 is tightened, the limiting support plate 7 will clamp the fire detection alarm 1, thereby limiting and assisting in fixing the alarm.

[0038] The connecting crossbar 12 is located at the rear end of the protective bracket 4. The number of supporting vertical bars 11 and connecting crossbar 12 is set to two, and the two supporting vertical bars 11 and connecting crossbar 12 are symmetrically distributed with the protective bracket 4 as the center.

[0039] The implementation principle of a fire alarm detector that is easy to assemble and disassemble in this embodiment is as follows: When the angle of the fire alarm detector 1 needs to be adjusted, an external force is applied to the supporting vertical rod 11, causing it to rotate around the rotating seat 10. The rotation of the supporting vertical rod 11 will drive the connecting horizontal rod 12 to move. The connecting horizontal rod 12 transmits this movement to the angle adjusting seat 13. The angle adjusting seat 13 changes its relative position to the protective bracket 4 or other components according to the force transmitted from the connecting horizontal rod 12, thereby realizing the adjustment of the angle of the fire alarm detector 1. This allows the fire alarm detector 1 to be used in different installation environments. It can accurately detect walls of different heights and inclinations. When installing the fire alarm detector 1, the limiting support plate 7 is placed inside the protective bracket 4, with its inner wall in contact with the surface of the fire alarm detector 1. The mounting screw 8 is inserted into the threaded hole of the fixed support plate 9 and screwed into the limiting support plate 7. By rotating the mounting screw 8, the fixed support plate 9 remains stationary. The limiting support plate 7 will move closer to or further away from the fixed support plate 9 depending on the screwing direction of the mounting screw 8. When the mounting screw 8 is tightened, the limiting support plate 7 will clamp the fire alarm detector 1, thereby limiting and assisting in fixing the alarm.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
