Description

Technical Field

[0001] This utility model relates to the field of image-type fire detector technology, and in particular to a suspended image-type fire detector. Background Technology

[0002] Suspended image-based fire detectors are high-efficiency fire detection devices based on video image analysis technology, primarily used for early fire warning in large spaces, high-rise buildings, and complex environments. Their core principle involves real-time image acquisition of the monitored area via a camera, followed by intelligent algorithm analysis of flame characteristics (such as dynamic flickering and color changes) or smoke patterns (such as diffusion patterns and transparency changes) to achieve rapid fire identification and alarm.

[0003] Currently, suspended image-type fire detectors are fixed to the building ceiling using suspension wires and bolts. During initial installation, mounting holes are drilled in the ceiling, and then the suspension wires are secured with bolts. This installation method cannot flexibly adjust the detector's position according to installation needs, making the installation rather rigid. Furthermore, after installation, maintenance and repair of the image-type fire detector require disassembling the mounting screws, making maintenance inconvenient and time-consuming. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a suspended image-type fire detector.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a suspended image-type fire detector, comprising a mounting plate and a detector body. A T-shaped guide rail is fixed to the lower surface of the mounting plate. A slide block is slidably connected to the surface of the T-shaped guide rail, and a cylinder is fixedly connected to the lower surface of the slide block. A bent rod is rotatably connected inside the cylinder via a bearing. A square groove is formed inside the bent rod at the end away from the cylinder. A square rod is slidably connected inside the square groove. A mounting sleeve is fixedly connected to the end of the square rod outside the square groove, and the bottom of the mounting sleeve is open. A locking hole is formed on the side of the mounting sleeve away from the square rod. A mounting assembly is fixed to the upper surface of the detector body, and the mounting assembly is locked and fixed to the mounting sleeve.

[0006] Furthermore, the bottom wall of the slide block is connected to a first locking bolt through a threaded connection, and one end of the first locking bolt located inside the slide block is in contact with the surface of the T-shaped guide rail.

[0007] Furthermore, end plates are fixed at both ends of the T-shaped guide rail.

[0008] Furthermore, a second locking bolt is threadedly connected to the side wall of the cylinder, and one end of the second locking bolt inside the cylinder is in contact with the outer side wall of the bent rod.

[0009] Furthermore, the top wall of the square groove near the mounting sleeve is penetrated and connected to a third locking bolt via a threaded connection, the bottom end of which is in contact with the surface of the square rod.

[0010] Furthermore, a strip-shaped opening is provided at the bottom of the square groove, and a slider is fixed on the lower surface of one end of the square rod inside the square groove, and the slider is slidably connected to the strip-shaped opening.

[0011] Furthermore, the mounting assembly includes a plug fixed to the upper surface of the detector body, and the plug is inserted into the mounting sleeve.

[0021] 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.

[0022] like Figures 1-3 As shown, a suspended image-type fire detector is disclosed, comprising a mounting plate 1 and a detector body 2. A T-shaped guide rail 3 is fixed to the lower surface of the mounting plate 1. A slide block 4 is slidably connected to the surface of the T-shaped guide rail 3, and a cylinder 5 is fixedly connected to the lower surface of the slide block 4. A bent rod 6 is rotatably connected inside the cylinder 5 via a bearing. A square groove 61 is opened inside the bent rod 6 at the end away from the cylinder 5. A square rod 7 is slidably connected inside the square groove 61. An installation sleeve 8 is fixedly connected to the end of the square rod 7 outside the square groove 61. The bottom of the installation sleeve 8 is open. A locking hole 81 is opened on the side of the installation sleeve 8 away from the square rod 7. An installation component 9 is fixed to the upper surface of the detector body 2, and the installation component 9 is locked and fixed to the installation sleeve 8.

[0023] The bottom wall of the slide 4 is connected to a first locking bolt through a threaded connection. One end of the first locking bolt inside the slide 4 is in contact with the surface of the T-shaped guide rail 3.

[0024] In this embodiment, the shape of the slide block 4 fits perfectly with the shape of the T-shaped guide rail 3, and the slide block 4 can slide along the surface of the T-shaped guide rail 3. After the slide block 4 has moved to the correct position, tightening the first locking bolt to press against the surface of the T-shaped guide rail 3 will fix the slide block 4.

[0025] Both ends of the T-shaped guide rail 3 are fixed with end plates 31.

[0026] By setting the end plate 31, the slide block 4 can be prevented from separating from the T-shaped guide rail 3 when sliding along the T-shaped guide rail 3.

[0027] The cylinder 5 has a second locking bolt 51 that runs through its side wall and is connected by a threaded rotation. One end of the second locking bolt 51 inside the cylinder 5 is in contact with the outer side wall of the bent rod 6.

[0028] One end of the bent rod 6 located inside the cylinder 5 can rotate inside the cylinder 5, thereby changing the direction of the bottom of the bent rod 6, which in turn changes the direction of the detector body 2. After adjustment, tighten the second locking bolt 51 to press and fix the surface of the bent rod 6.

[0029] The top wall of the square groove 61 near the mounting sleeve 8 is penetrated and connected to the second locking bolt 51 by a threaded rotation. The bottom end of the second locking bolt 51 is in contact with the surface of the square rod 7.

[0030] By moving the square rod 7 along the square groove 61, the position of the detector body 2 can be further adjusted. After adjustment, tighten the third locking bolt 63 to press and fix the square rod 7.

[0031] The bottom of the square groove 61 has a strip-shaped opening 62. A slider 71 is fixed on the lower surface of one end of the square rod 7 inside the square groove 61. The slider 71 is slidably connected to the strip-shaped opening 62.

[0032] By setting the slider 71 to move along the slot 62, the separation of the square rod 7 from the square groove 61 can be avoided.

[0033] The mounting assembly 9 includes a plug 91 fixed to the upper surface of the detector body 2, and the plug 91 is inserted into the mounting sleeve 8. The plug 91 has a groove 92 on the side near the card hole 81. A spring 93 is fixedly connected to the inner wall of the groove 92. A locking rod 94 is fixedly connected to the other end of the spring 93. The end of the locking rod 94 away from the spring 93 is inserted into the card hole 81.

[0034] When connecting the mounting component 9 to the mounting sleeve 8, first press the locking rod 94 on the insert block 91, causing the locking rod 94 to retract into the groove 92. At this time, the spring 93 is compressed. Then, insert the insert block 91 from the bottom of the mounting sleeve 8 into the interior of the mounting sleeve 8. The spring 93 will then press the locking rod 94 into the locking hole 81, thus achieving a fixed connection between the mounting sleeve 8 and the insert block 91, which in turn achieves a fixed connection between the detector body 2 and the square rod 7. For subsequent disassembly and maintenance, simply press the locking rod 94 to separate it from the locking hole 81, and then remove the insert block 91 from the interior of the mounting sleeve 8.

[0035] Working principle: During installation, the mounting plate 1 is fixed to the building ceiling with bolts. The position of the detector body 2 can then be adjusted by moving the sliding block 4 and the square rod 7. After adjustment, tighten the first and third locking bolts 63. Next, rotate the bent rod 6 to further adjust the direction of the detector body 2. After adjustment, tighten the second locking bolt 51 to fix the bent rod 6. When the detector body 2 needs to be inspected later, squeeze the locking rod 94 to separate it from the locking hole 81, and then remove the insert 91 from inside the mounting sleeve 8.
