Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, and particularly relates to a mounting bracket for a fire detector. Background Art

[0002] A fire detector is a device used to detect signs of a fire, usually for improving the safety of buildings. It detects the occurrence of a fire by monitoring different indicators in the environment; when a fire breaks out, different fire detectors can convert physical quantities with different characteristics, such as temperature, smoke, gas, and flame radiation, into electrical signals and send alarm signals to a fire alarm controller to achieve the purpose of extinguishing the fire in a timely manner; when existing fire detectors are in use, the installed position is usually fixed, and the detectable space is also limited, with a small scope of application.

[0003] In view of the above situation, there is currently a special image-type fire detector for large spaces on the market, such as a Chinese patent with the application number CN202221717461.7. This fire detector includes a mounting plate (1), the mounting plate (1) is connected to a wall through a plurality of screws, a bracket (2) is fixedly assembled on the side surface of the mounting plate (1) away from the wall, a hydraulic cylinder (3) is connected to the surface of the bracket (2) through two supports (4), a support platform (5) is fixedly assembled at the outer end of the piston rod of the hydraulic cylinder (3), both side walls of the support platform (5) are connected to the bracket (2) through a limiting structure (8), a card slot (10) is fixedly assembled at the upper end of the support platform (5), and a fire detector (11) is connected to the inner wall of the card slot (10) through screws; this fire detector is connected to the wall surface through the mounting plate to ensure the stability of the bracket. The mounting plate has a large area and can be assembled with multiple screws to better ensure stability and is also convenient for disassembly. Through the role of the bracket, as the carrier of the fire detector, it ensures the stability of the fire detector. Through the setting of the support platform and the card slot, it is convenient to install the fire detector. Through the setting of the hydraulic cylinder and the use effect of the hydraulic cylinder, it is convenient to move the support platform and at the same time move the fire detector to ensure a wide range of use of the fire detector.

[0004] However, although the fire detector has many advantages as described above, during the actual use process, the inventor found that the fire detector still has deficiencies, specifically:

[0005] First, the bracket of the fire detector is directly connected to the wall through bolts. In this way, when problems occur with the components of the fire detector and need to be repaired or replaced, the bolts need to be unscrewed from the wall in order to remove the bracket and the components on the bracket. Since the wall is usually made of reinforced concrete structure and the bolts used are usually expansion bolts, the original screw hole structure will be damaged after unscrewing the bolts. When the bracket is reinstalled at the original screw hole position, its stability is difficult to guarantee. If the installation position is changed, new holes need to be drilled again, which increases the workload. At the same time, it may cause the fire detector to lose its optimal installation position, further resulting in detection blind spots and increasing the risk of fire occurrence. Secondly, the fire detector can move in a certain direction under the action of the hydraulic cylinder. Although the detection range in this moving direction is increased, the detection ranges in other directions are still limited, and there are still detection blind spots. In order to reduce the detection blind spots, it may be necessary to install fire detectors in multiple directions at the same position, increasing the usage and maintenance costs.

[0006] Therefore, based on the above deficiencies, there is an urgent need to design a mounting bracket for a fire detector at present. Utility Model Content

[0007] The purpose of the present utility model is to provide a mounting bracket for a fire detector in view of the above deficiencies in the limited detection range of the fire detector during actual use.

[0008] In order to achieve the above utility model purpose, the present utility model provides the following technical solutions:

[0009] A mounting bracket for a fire detector, comprising a bracket body, one end of the bracket body is connected to the wall, and a fire detector is provided at the other end. A first rotating mechanism is provided on the bracket body, and the first rotating mechanism enables the fire detector to rotate 360 degrees in the horizontal direction.

[0010] As a preferred technical solution of the present application, the rotating mechanism includes a first rotating shaft rotatably connected to the bracket body. One end of the first rotating shaft is provided with the fire detector, and the other end is provided with a first gear. The first gear meshes with a second gear, and the second gear is provided on the rotating shaft of the motor, and the motor provides power for the rotation of the second gear.

[0011] As a preferred technical solution of the present application, the number of teeth of the first gear is greater than the number of teeth of the second gear.

[0012] As a preferred technical solution of the present application, a first bearing is provided between the bracket body and the first rotating shaft, and the first bearing is in interference fit with the first rotating shaft.

[0013] As a preferred technical solution of the present application, a second rotating mechanism is provided below the first rotating shaft, and the second rotating mechanism enables the fire detector to perform a rotating motion within a preset angle in the vertical direction.

[0014] As a preferred technical solution of the present application, the second rotating mechanism includes a cylinder. One end of the cylinder is bolted to the first rotating shaft, and the piston rod at the other end is movably connected to one end of a first connecting seat. The fire detector is bolted to the other end of the first connecting seat;

[0015] A through groove is provided at one end of the first connecting seat connected to the piston rod, and a second rotating shaft is provided on the piston rod. The through groove is adapted to the second rotating shaft so that the second rotating shaft can slide and rotate in the through groove; A first connecting member is provided between the cylinder block of the cylinder and the first connecting seat. One end of the first connecting member is bolted to the cylinder block of the cylinder, and the other end is rotatably connected to the middle position of the first connecting seat.

[0016] As a preferred technical solution of the present application, a second connecting seat is further provided on the bracket body. A clamping groove is provided on the second connecting seat, and a clamping plate is provided on the bracket body. The clamping plate is adapted to the clamping groove, and the second connecting seat is connected to the wall through bolts.

[0017] As a preferred technical solution of the present application, a fixing device is provided on the second connecting seat, and the fixing device is used to fix the bracket body on the second connecting seat;

[0018] The fixing device includes a base, a plug pin and a spring. The base is bolted to the surface of the second connecting seat. The plug pin is slidably arranged in the base. The plug pin penetrates from the outside of the second connecting seat into the clamping groove. A groove is provided on the clamping plate, and the size of the groove is adapted to the size of the plug pin. The plug pin is sleeved with the spring. Under the action of the spring, when the clamping plate is inserted into the clamping groove, the plug pin abuts against the groove; Under the action of an external force, pulling the plug pin can make the plug pin disengage from the groove.

[0019] As a preferred technical solution of the present application, a first limiting block is provided in the base, and a second limiting block is provided corresponding to the plug pin. When the second limiting block abuts against the first limiting block, the plug pin disengages from the groove.

[0020] As a preferred technical solution of the present application, the bracket body is L-shaped, and one side of the clamping plate is bent upward.

[0021] Compared with the prior art, the beneficial effects of the present utility model:

[0022] 1. In the solution of this application, by setting the first rotating mechanism, the fire detector can rotate 360 degrees horizontally. Compared with the single movement of the fire detector in a certain direction in the prior art, the detection area it can cover is greatly increased, which is conducive to detecting a fire in a timely manner. Further, since the fire detector can rotate 360 degrees horizontally, thus, only one mounting bracket of this application needs to be installed at an appropriate position, and the fire detector on the mounting bracket can detect in multiple directions, reducing the use and maintenance costs of the fire detector.

[0023] 2. The rotation of the motor drives the second gear to rotate, the rotation of the second gear drives the first gear to rotate, the rotation of the first gear drives the first rotating shaft to rotate, and the rotation of the first rotating shaft drives the fire detector to rotate, realizing the 360-degree rotation of the fire detector horizontally.

[0024] 3. The setting of the second rotating mechanism further increases the detection range of the fire detector. On the one hand, it is conducive to detecting a fire in a timely manner. On the other hand, it can reduce the number of installed fire detectors, reducing the use and maintenance costs. When it is necessary to adjust the angle of the fire detector in the vertical direction, air is introduced into the cylinder to make the piston rod extend. Under the action of the second rotating shaft, the through groove slides relative to the second rotating shaft. Under the action of the first connecting piece, the first connecting seat rotates clockwise, and the rotation of the first connecting seat drives the fire detector to rotate upward and tilt. Similarly, air is introduced into the cylinder to make the piston rod contract. Under the action of the second rotating shaft, the through groove slides relative to the second rotating shaft. Under the action of the first connecting piece, the first connecting seat rotates counterclockwise, and the rotation of the first connecting seat drives the fire detector to rotate downward and tilt. Thus, the fire detector realizes a rotational movement within a preset angle in the vertical direction, further expanding the detection range and being conducive to detecting a fire in a timely manner.

[0025] 4. The setting of the clamping plate and the clamping groove facilitates the installation and disassembly of the bracket body. When maintaining or replacing components, the bracket body only needs to be removed from the second connecting seat. Thus, it avoids removing bolts and damaging the screw hole structure on the wall, ensuring the installation position of the bracket body and the detection range of the fire detector.

[0026] 5. The setting of the fixing device increases the connection stability between the bracket body and the second connecting seat. Specifically, during the process of inserting the clamping plate into the clamping groove, the lower end of the clamping plate acts on the front end of the plug pin, causing the plug pin to move backward. When the lower end of the clamping plate contacts the bottom of the clamping groove, the plug pin is inserted into the groove under the action of the spring, ensuring the reliable connection between the clamping plate and the clamping groove and the stability of the fire detector during rotation.

[0037] Embodiment 1: Refer to Figures 1 to 3 as shown in

[0038] A fire detector mounting bracket provided in this embodiment includes a bracket body 1. One end of the bracket body 1 is connected to a wall, and a fire detector 2 is provided at the other end. A first rotating mechanism 3 is provided on the bracket body 1, and the first rotating mechanism 3 enables the fire detector 2 to rotate 360 degrees in the horizontal direction.

[0039] In this embodiment, by providing the first rotating mechanism 3, the fire detector 2 can rotate 360 degrees in the horizontal direction. Compared with the single movement of the fire detector 2 in a certain direction in the prior art, the detection area can be greatly increased, which is beneficial to detecting a fire in a timely manner. Further, since the fire detector 2 can rotate 360 degrees in the horizontal direction, thus, only one mounting bracket of the present application needs to be installed at a suitable position, and the fire detector 2 on the mounting bracket can detect multiple directions, reducing the use and maintenance costs of the fire detector 2.

[0040] As a preferred embodiment, on the basis of the above method, further, the rotating mechanism includes a first rotating shaft 31 rotatably connected to the bracket body 1. One end of the first rotating shaft 31 is provided with the fire detector 2, and the other end is provided with a first gear 32. The first gear 32 meshes with a second gear 33, and the second gear 33 is provided on the rotating shaft of a motor 34. The motor 34 provides power for the rotation of the second gear 33.

[0041] The rotation of the motor 34 drives the rotation of the second gear 33. The rotation of the second gear 33 drives the rotation of the first gear 32. The rotation of the first gear 32 drives the rotation of the first rotating shaft 31. The rotation of the first rotating shaft 31 drives the rotation of the fire detector 2, realizing the 360-degree rotation of the fire detector 2 in the horizontal direction.

[0042] As a preferred embodiment, on the basis of the above method, further, the number of teeth of the first gear 32 is greater than the number of teeth of the second gear 33.

[0043] With the above structure, the deceleration effect is achieved, and the stability of the fire detector 2 during rotation is improved.

[0044] As a preferred embodiment, on the basis of the above method, further, a first bearing 35 is provided between the bracket body 1 and the first rotating shaft 31, and the first bearing 35 is in interference fit with the first rotating shaft 31.

[0045] The setting of the first bearing 35 reduces the friction and wear between the first rotating shaft 31 and the bracket body 1, making the rotational connection between the first rotating shaft 31 and the bracket body 1 more stable, and further improving the stability of the fire detector 2 during rotation.

[0046] As a preferred embodiment, on the basis of the above method, further, a second rotating mechanism 4 is provided below the first rotating shaft 31, and the second rotating mechanism 4 enables the fire detector 2 to perform a rotational movement within a preset angle in the vertical direction.

[0047] The setting of the second rotating mechanism 4 further increases the detection range of the fire detector 2. On the one hand, it is beneficial to detect the fire in time, and on the other hand, it can reduce the installation quantity of the fire detector 2 and lower the use and maintenance costs.

[0048] As a preferred embodiment, on the basis of the above method, further, the second rotating mechanism 4 includes a cylinder 41. One end of the cylinder 41 is bolted to the first rotating shaft 31, and the piston rod 42 at the other end is movably connected to one end of a first connecting seat 43. The other end of the first connecting seat 43 is bolted with the fire detector 2;

[0049] A through groove 431 is provided at the end of the first connecting seat 43 connected to the piston rod 42, and a second rotating shaft 421 is provided on the piston rod 42. The through groove 431 is adapted to the second rotating shaft 421 so that the second rotating shaft 421 can slide and rotate in the through groove 431; a first connecting member 44 is provided between the cylinder block of the cylinder 41 and the first connecting seat 43. One end of the first connecting member 44 is bolted to the cylinder block of the cylinder 41, and the other end is rotatably connected to the middle position of the first connecting seat 43.

[0050] When it is necessary to adjust the angle of the fire detector 2 in the vertical direction, air is introduced into the cylinder 41 to make the piston rod 42 extend. Under the action of the second rotating shaft 421, the through groove 431 slides relative to the second rotating shaft 421. Under the action of the first connecting member 44, the first connecting seat 43 rotates clockwise, and the rotation of the first connecting seat 43 drives the fire detector 2 to tilt upward; similarly, air is introduced into the cylinder 41 to make the piston rod 42 contract. Under the action of the second rotating shaft 421, the through groove 431 slides relative to the second rotating shaft 421. Under the action of the first connecting member 44, the first connecting seat 43 rotates counterclockwise, and the rotation of the first connecting seat 43 drives the fire detector 2 to tilt downward; thus, the fire detector 2 realizes rotational movement within a preset angle in the vertical direction, further expanding the detection range and facilitating the timely discovery of a fire.

[0051] As a preferred embodiment, on the basis of the above method, further, a second connecting seat 5 is further provided on the bracket body 1. A clamping groove 41 is provided on the second connecting seat 5, a clamping plate 11 is provided on the bracket body 1, the clamping plate 11 is adapted to the clamping groove 41, and the second connecting seat 5 is connected to the wall through bolts.

[0052] The arrangement of the clamping plate 11 and the clamping groove 41 facilitates the installation and disassembly of the bracket body 1. When maintaining or replacing parts, the bracket body 1 can be simply removed from the second connecting seat 5. In this way, the removal of bolts is avoided, the screw hole structure on the wall is not damaged, the installation position of the bracket body 1 is ensured, and the detection range of the fire detector 2 is ensured.

[0053] As a preferred embodiment, on the basis of the above method, further, a fixing device 6 is provided on the second connecting seat 5, and the fixing device 6 is used to fix the bracket body 1 on the second connecting seat 5;

[0054] The fixing device 6 includes a base 61, a plug pin 62 and a spring 63. The base 61 is connected to the surface of the second connecting seat 5 through bolts. The plug pin 62 is slidably arranged in the base 61. The plug pin 62 penetrates from the outside of the second connecting seat 5 into the clamping groove 41. A groove 111 is provided on the clamping plate 11, and the size of the groove 111 is adapted to the size of the plug pin 62. The spring 63 is sleeved on the plug pin 62. Under the action of the spring 63, when the clamping plate 11 is inserted into the clamping groove 41, the plug pin 62 abuts against the groove 111; under the action of an external force, pulling the plug pin 62 can make the plug pin 62 disengage from the groove 111.

[0055] The setting of the fixing device 6 increases the stability of the connection between the bracket body 1 and the second connecting seat 5. Specifically, during the process of inserting the clamping plate 11 into the clamping groove 41, the lower end of the clamping plate 11 acts on the front end of the bolt 62, causing the bolt 62 to move backward. When the lower end of the clamping plate 11 contacts the bottom of the clamping groove 41, the bolt 62 is inserted into the groove 111 under the action of the spring 63, ensuring the reliable connection between the clamping plate 11 and the clamping groove 41 and ensuring the stability when the fire detector 2 rotates.

[0056] As a preferred embodiment, on the basis of the above method, further, a first limiting block 611 is arranged in the base 61, and a second limiting block 621 is arranged corresponding to the bolt 62. When the second limiting block 621 abuts against the first limiting block 611, the bolt 62 disengages from the groove 111.

[0057] The settings of the first limiting block 611 and the second limiting block 621 facilitate the disassembly of the bracket body 1. During operation, first pull up the bolt 62, then rotate it by a certain angle so that the positions of the second limiting block 621 and the first limiting block 611 overlap. Release the bolt 62. Under the action of the spring 63, the first limiting block 611 abuts against the second limiting block 621, and the bolt 62 disengages from the groove 111. Removing the clamping plate 11 from the clamping groove 41 realizes the removal of the bracket body 1. In this way, the operator can first operate the bolt 62 to make the bolt 62 disengage from the groove 111, and then remove the bracket body 1 with both hands, which is beneficial to protecting the bracket body 1 and the components on the bracket body 1.

[0058] Embodiment 2: Refer to Figure 4 as shown in

[0059] The difference between this embodiment and Embodiment 1 is that the bracket body 1 is L-shaped, and one side of the clamping plate 11 is bent upward.
