[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an adjustable ceiling fire-fighting equipment installation bracket, including a supporting top plate 1, a first rotating joint 2 is provided at the bottom end of the supporting top plate 1, an adjusting support rod outer rod 3 is connected below the first rotating joint 2, and an equipment mounting base 4 is provided below the adjusting support rod outer rod 3.

[0027] The upper surface of the equipment mounting base 4 is provided with a second rotary joint 5. The end of the second rotary joint 5 away from the equipment mounting base 4 is connected to the inner rod 6 of the adjusting support rod. The inner rod 6 of the adjusting support rod is movably connected to the outer rod 3 of the adjusting support rod. Both the first rotary joint 2 and the second rotary joint 5 are movable joints that can rotate 360° to flexibly adjust the angle of the outer rod 3 and the inner rod 6 of the adjusting support rod. The equipment mounting base 4 is provided with an installation interface adapted to the fire protection equipment. The type of installation interface is designed according to the connection method of the fire protection equipment. The supporting top plate 1, the outer rod 3 of the adjusting support rod, the inner rod 6 of the adjusting support rod, and the equipment mounting base 4 are all made of metal materials and the surface is treated with anti-corrosion.

[0028] Based on fire protection design requirements and actual site conditions, the installation position of the supporting ceiling plate 1 is determined on the suspended ceiling. This position must ensure that the fire protection equipment can effectively cover the protected area after installation. For example, for fire sprinkler heads, it is necessary to ensure that their spray range can fully cover the target area. Using the 360° rotation function of rotary joint 2 and rotary joint 5, the angles of the outer rod 3 and inner rod 6 of the adjusting support rod are initially adjusted so that the equipment mounting base 4 is roughly in the appropriate direction and angle, preparing for the subsequent installation of the fire protection equipment. The fire protection equipment is then installed through the appropriate installation interface on the equipment mounting base 4. The type of installation interface is specially designed according to the connection method of the fire protection equipment. For example, for fire sprinkler heads with threaded connections, the mounting interface on the equipment mounting base 4 is a threaded interface of the corresponding specification. For smoke detectors with snap-fit ​​connections, the mounting interface is a matching snap-fit ​​structure. Through this matching mounting interface, the fire equipment can be firmly installed on the equipment mounting base 4. After the fire equipment is installed, the angle of the fire equipment can be finely adjusted with the help of the first rotary joint 2 and the second rotary joint 5 so that the detection range and spray direction of the fire equipment meet the design requirements. For example, for fire sprinkler heads, it is necessary to ensure that the spray coverage area is uniform and without dead corners. For smoke detectors, it is necessary to ensure that they can accurately detect smoke in the protected area.

[0029] The outer surface of the adjusting support rod 3 is provided with evenly distributed positioning holes 7. The outer side of the adjusting support rod 3 is connected to a positioning pin 8 through the positioning holes 7. The positioning pin 8 is movably connected to the inner rod 6 of the adjusting support rod. The supporting top plate 1 is provided with several mounting holes 9. The inner rod 6 of the adjusting support rod can freely extend and retract within the adjusting support rod 3. The overall length of the adjusting support rod can be adjusted by engaging the positioning pin 8 with the positioning holes 7 at different positions. The positioning pin 8 and the inner rod 6 of the adjusting support rod are detachably connected, which facilitates the replacement or maintenance of the positioning pin 8. The mounting holes 9 are circular or elliptical in shape, and the inner wall of the mounting holes 9 is threaded for use with different types of connectors to fix the supporting top plate 1 to the ceiling.

[0030] Based on the ceiling height and fire equipment installation height requirements, the length of the adjusting rod is initially adjusted. Specifically, the positioning pin 8 is first pulled out from the inner rod 6 of the adjusting rod, releasing the fixing between the inner rod 6 and the outer rod 3. Then, according to the required length, the inner rod 6 is extended or retracted within the outer rod 3. Once the appropriate length is reached, the positioning pin 8 is inserted into the corresponding hole in the inner rod 6 and engaged with the corresponding positioning hole 7 on the outer rod 3, thus fixing the length of the adjusting rod. Then, based on the shape and size of the mounting hole 9, suitable connectors, such as bolts or expansion screws, are selected. Since the inner wall of the mounting hole 9 has threads, the connectors can be fitted with the mounting hole 9 for installation. The supporting ceiling plate 1 is then securely fixed to the pre-determined ceiling position using the connectors, ensuring the supporting ceiling plate 1 is securely installed. The system is stable and can withstand the weight of fire-fighting equipment and the adjusting rod. If the length of the adjusting rod needs further precise adjustment, the positioning pin 8 can be pulled out again, and the inner rod 6 of the adjusting rod can be extended or retracted within a small range. Then, the positioning pin 8 can be reinserted and engaged with the positioning hole 7 to ensure that the fire-fighting equipment is at the optimal installation height. During normal use of the fire protection system, if there are changes in ceiling height or replacement of fire-fighting equipment, the hanger can be adjusted accordingly by adjusting the length of the rod and the angle of the rotating joint, following the above adjustment method. At the same time, since the positioning pin 8 and the inner rod 6 of the adjusting rod are detachably connected, the positioning pin 8 can be easily replaced when damaged. Furthermore, the supporting top plate 1, the outer rod 3 of the adjusting rod, the inner rod 6 of the adjusting rod, and the equipment mounting base 4 are all made of corrosion-resistant metal materials, which can effectively extend the service life of the hanger and reduce maintenance costs.

[0031] Working Principle: Based on fire protection design requirements and actual site conditions, the installation position of the supporting ceiling plate 1 is determined on the suspended ceiling. This position must ensure that the fire protection equipment can effectively cover the protected area after installation. For example, for fire sprinkler heads, it is necessary to ensure that their spray range can fully cover the target area. According to the requirements of the suspended ceiling height and the installation height of the fire protection equipment, the length of the adjusting rod is initially adjusted. Specifically, the positioning pin 8 is first pulled out from the inner rod 6 of the adjusting rod, releasing the fixed state between the inner rod 6 and the outer rod 3. Then, according to the required length, the inner rod 6 of the adjusting rod is extended or retracted within the outer rod 3. After adjusting to the appropriate length, the positioning pin 8 is inserted into the corresponding hole of the inner rod 6 of the adjusting rod, and aligned with the corresponding position on the outer rod 3. The positioning hole 7 is engaged to fix the length of the adjusting support rod. Using the 360° rotation function of rotary joint 2 and rotary joint 5, the angles of the outer rod 3 and inner rod 6 of the adjusting support rod are initially adjusted, so that the equipment mounting base 4 is roughly in the appropriate direction and angle, preparing for the subsequent installation of the fire-fighting equipment. Then, according to the shape and size of the mounting hole 9, appropriate connectors, such as bolts and expansion screws, are selected. Since the inner wall of the mounting hole 9 has threads, the connectors can be fitted with the mounting hole 9 for installation. The supporting top plate 1 is firmly fixed to the pre-determined ceiling position using the connectors, ensuring the stable installation of the supporting top plate 1 and its ability to bear the weight of the fire-fighting equipment and the adjusting support rod. The fire-fighting equipment is then installed using the appropriate mounting bracket on the equipment mounting base 4. The installation is carried out using the mounting interface. The type of mounting interface is specifically designed according to the connection method of the fire-fighting equipment. For example, for fire sprinkler heads using threaded connections, the mounting interface on the equipment mounting base 4 is a threaded interface of the corresponding specification. For smoke detectors using snap-fit ​​connections, the mounting interface is a matching snap-fit ​​structure. Through this matching mounting interface, the fire-fighting equipment can be firmly installed on the equipment mounting base 4. After the fire-fighting equipment is installed, if it is found that the length of the adjusting rod needs further precise adjustment, the positioning pin 8 can be pulled out again, and the inner rod 6 of the adjusting rod can be extended or retracted within a small range. Then, the positioning pin 8 can be reinserted and engaged with the positioning hole 7 to ensure that the fire-fighting equipment is at the optimal installation height. With the help of the first rotary joint 2 and the second rotary joint 5, the fire-fighting equipment can be... The angles of the equipment are finely adjusted to ensure that the detection range and spray direction of the fire-fighting equipment meet design requirements. For example, for fire sprinkler heads, it is necessary to ensure that the spray coverage area is uniform and without dead corners. For smoke detectors, it is necessary to ensure that they can accurately detect smoke within the protected area. During normal use of the fire protection system, if there are changes in ceiling height or replacement of fire-fighting equipment, the hanger can be adjusted accordingly by adjusting the length of the support rod and the angle of the swivel joint, following the above adjustment methods. At the same time, since the positioning pin 8 and the inner rod 6 of the adjusting support rod are detachably connected, the positioning pin 8 can be easily replaced when damaged. Furthermore, the supporting top plate 1, the outer rod 3 of the adjusting support rod, the inner rod 6 of the adjusting support rod, and the equipment mounting base 4 are all made of corrosion-resistant metal materials.This can effectively extend the service life of the hanger and reduce maintenance costs.
