Description

Technical Field

[0001] The utility model relates to the technical field of fire detectors, in particular to a fire detector. Background Art

[0002] A fire detector is a device that explores the scene and discovers fires in the automatic fire alarm system of a fire. Its function is to monitor whether there is a fire in the environment. Once there is a fire, it converts the characteristic physical quantities of the fire, such as temperature, smoke, gas, and radiation light intensity, into electrical signals and immediately sends an alarm signal to the fire alarm controller.

[0003] For example, a fire detector for the Internet of Things disclosed in the utility model with the authorization announcement number CN217484959U, which relates to the technical field of fire detectors, includes a base. A fixing frame is installed on the top of the base, and a smoke detector is arranged inside the fixing frame. A fixing groove is opened inside the base, and a controller is arranged inside the fixing groove. The smoke detector on the fire detector transmits signals to the controller. The controller first controls the alarm to sound the alarm. Whether there is anyone in the room or not, the controller will also control the signal transmission module to transmit the signals transmitted by the smoke detector to the user's mobile phone terminal or other electronic terminals. Finally, the user can locate the position of the fire detector transmitting the signal according to the GPS positioning module and take timely and effective measures, so as to help the user reduce losses as much as possible. At the same time, it also effectively avoids the long-term spread of the fire, thereby improving the use performance of the device and reflecting the practicability of the device. However, this device has similar characteristics to existing fire detectors, that is, it is installed on the ceiling or wall through a mounting plate, the fire detector cannot be moved, and the detection range is also fixed. When the distance of the fire is relatively far, it cannot be detected in time. In addition, the fire detector is often installed and fixed by multiple bolts, and it cannot be quickly disassembled when maintenance or replacement is required. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a fire detector, which can solve the technical problems that this device has similar characteristics to existing fire detectors, that is, it is installed on the ceiling or wall through a mounting plate, the fire detector cannot be moved, and the detection range is also fixed. When the distance of the fire is relatively far, it cannot be detected in time. In addition, the fire detector is often installed and fixed by multiple bolts, and it cannot be quickly disassembled when maintenance or replacement is required.

[0005] To solve the above technical problems, the present utility model provides the following technical solution: A fire detector includes a first bracket, on one side of which there is a motor. The output end of the motor penetrates through the first bracket and is fixedly connected to a threaded rod. One end of the threaded rod is rotatably connected to the first bracket. A connecting block is threadedly connected to the threaded rod, and a limiting rod is fixedly connected to the first bracket. The limiting rod penetrates through the connecting block. A fixed block is fixedly connected to the lower end of the connecting block. A slot is opened on one side of the fixed block, and an insertion block is inserted into the slot. A limiting groove is opened on one side of the insertion block, and the limiting groove cooperates with a limiting component. And a fire detector body is arranged at the lower end of the fixed block.

[0006] As a preferred technical solution of the present utility model, the limiting component includes the following: A second bracket is fixedly connected to one side of the fixed block. A cross bar passes through the second bracket. One end of the cross bar is fixedly connected to a handle, and a limiting block is fixedly connected to one end of the cross bar. And a spring is fixedly connected between the limiting block and the second bracket. The limiting block can penetrate through a through hole on the fixed block and be inserted into the limiting groove.

[0007] As a preferred technical solution of the present utility model, the cross-sectional sizes of the through hole and the limiting groove are exactly the same.

[0008] As a preferred technical solution of the present utility model, a cross plate is fixedly connected to one side of the fixed block.

[0009] As a preferred technical solution of the present utility model, a threaded sleeve is fixedly connected to the lower end of the cross plate. A threaded column is threadedly connected to the threaded sleeve, and a micro camera is arranged at the lower end of the threaded column.

[0010] As a preferred technical solution of the present utility model, a pair of mounting plates are fixedly connected to both sides of the first bracket.

[0011] Compared with the prior art, the beneficial effects that the present utility model can achieve are:

[0012] 1. By starting the motor, the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the connecting block to move. And the connecting block can move more stably under the limiting effect of the limiting rod. While the connecting block moves, it can drive the fixed block and the fire detector body to move, thereby increasing the detection range and avoiding the situation that the distance of the fire occurrence is relatively far and the induction detection cannot be carried out in time.

[0013] 2. By pulling the handle, the handle drives the cross bar and the limiting block to move to one side. At the same time, the spring contracts until the limiting block leaves the limiting groove and the through hole, so that the insertion block is no longer fixed, and the insertion block can be taken out from the slot, thereby realizing the quick disassembly of the fire detector body.

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0020] Embodiment

[0021] Please refer to Figures 1-3 As shown, the present utility model provides a fire detector. The cross-sectional sizes of the through hole 16 and the limiting groove 9 are exactly the same, and the cross-sectional size thereof is also exactly the same as that of the limiting block 15. One side of the fixed block 6 is fixedly connected with a horizontal plate 17. The lower end of the horizontal plate 17 is fixedly connected with a threaded sleeve 18. The threaded sleeve 18 is internally threaded with a threaded column 19, and the lower end of the threaded column 19 is provided with a miniature camera 20. Both sides of the first bracket 1 are fixedly connected with a pair of mounting plates 21, and the mounting plates 21 are symmetric with each other in pairs.

[0022] During use, the miniature camera 20 can be used to well view the fire location and the fire situation in advance. And when the miniature camera 20 needs to be repaired and disassembled, the miniature camera 20 and the threaded column 19 can be rotated, and the threaded column 19 can be removed from the threaded sleeve 18 by only rotating one week, thereby realizing the disassembly of the miniature camera 20.

[0023] As a further implementation manner of this embodiment, asFigures 1-4 As shown in the figure, a motor 2 is provided on one side of the first bracket 1. The output end of the motor 2 penetrates through the first bracket 1 and is fixedly connected to a threaded rod 3. One end of the threaded rod 3 is rotatably connected to the first bracket 1. A connecting block 4 is threadedly connected to the threaded rod 3. A limiting rod 5 is fixedly connected to the first bracket 1. The limiting rod 5 is located above the threaded rod 3. The limiting rod 5 penetrates through the connecting block 4. The limiting rod 5 can play a role in limiting the connecting block 4 well. A fixed block 6 is fixedly connected to the lower end of the connecting block 4. A slot 7 is provided on one side of the fixed block 6. An insertion block 8 is inserted into the slot 7. A limiting groove 9 is provided on one side of the insertion block 8. The limiting groove 9 cooperates with a limiting component. A fire detector body 10 is provided at the lower end of the fixed block 6; the limiting component includes the following: A second bracket 11 is fixedly connected to one side of the fixed block 6. A cross bar 12 is passed through the second bracket 11. One end of the cross bar 12 is fixedly connected to a handle 13. One end of the cross bar 12 is fixedly connected to a limiting block 15. A spring 14 is fixedly connected between the limiting block 15 and the second bracket 11. The limiting block 15 can penetrate through a through hole 16 on the fixed block 6 and be inserted into the limiting groove 9.

[0024] When in use, by starting the motor 2, the motor 2 drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 drives the connecting block 4 to move. And the connecting block 4 can move more stably under the limiting action of the limiting rod 5. When the connecting block 4 moves, it can drive the fixed block 6 and the fire detector body 10 to move. And since the motor 2 on this device is a stepper motor 2, the rotation time and the rotation direction (i.e., forward rotation and reverse rotation) can be well controlled. Thus, the connecting block 4 and the fire detector body 10 can be reciprocally moved horizontally along the threaded rod 3 and the limiting rod 5, thereby greatly increasing the detection range and avoiding the failure to timely sense and detect due to the relatively far distance of the fire occurrence; in addition, by pulling the handle 13, the handle 13 drives the cross bar 12 and the limiting block 15 to move to one side. At the same time, the spring 14 contracts until the limiting block 15 leaves the limiting groove 9 and the through hole 16, so that the insertion block 8 is no longer fixed. The insertion block 8 can be taken out of the slot 7, thereby realizing the rapid disassembly of the fire detector body 10.

[0025] Specific working principle: When in use, by starting the motor 2, the motor 2 drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 drives the connecting block 4 to move. And the connecting block 4 can move more stably under the limiting action of the limiting rod 5. While the connecting block 4 moves, it can drive the fixed block 6 and the fire detector body 10 to move. And since the motor 2 on this device is a stepping motor 2, it can well control the rotation time and the rotation direction (i.e., forward rotation and reverse rotation). Thus, it can well make the connecting block 4 and the fire detector body 10 reciprocate horizontally along the threaded rod 3 and the limiting rod 5, thereby greatly increasing the detection range and avoiding the situation that the distance of the fire occurrence is relatively far and the detection cannot be timely sensed; in addition, by pulling the handle 13, the handle 13 drives the cross bar 12 and the limiting block 15 to move to one side. At the same time, the spring 14 contracts until the limiting block 15 leaves the limiting groove 9 and the through hole 16, so that the plug block 8 is no longer fixed, and the plug block 8 can be taken out from the slot 7, thereby realizing the quick disassembly of the fire detector body 10. Through this device, the detection range can be increased, the situation that the distance of the fire occurrence is relatively far and the detection cannot be timely sensed can be avoided, and at the same time, the quick disassembly of the fire detector body 10 can be realized.
