Abstract
Description
Technical Field
[0001] This invention belongs to the field of fire protection equipment technology, specifically relating to a sprinkler head positioning adjustment device. Background Technology
[0002] During the construction of fire protection water systems in buildings, the placement of sprinkler heads often results in uneven heights after placement due to errors in material measurement and processing or improper control by workers. This leads to a failure to perfectly align the sprinkler heads with the ceiling, severely impacting aesthetics and making adjustments labor-intensive. Specifically, the current conventional solution involves: determining the finished ceiling height based on the ceiling surface, identifying the sprinkler head locations based on the ceiling layout, measuring the length of each branch pipe, cutting and threading the pipes according to the measurements, and connecting them using fittings such as elbows, tees, and concentric reducers to complete the assembly and install the sprinkler heads at the designated positions and heights. However, this existing technology requires extremely precise positioning of the finished ceiling surface, sprinkler head placement, and material measurement. Furthermore, pipe cutting and threading must consider the space required for the fittings. With multiple steps involved, precision control is difficult, and any errors after completion severely affect aesthetics. Moreover, modifications are cumbersome. Utility Model Content

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
[0021] The following embodiments can be understood as a part of the local structure or method of the present invention, or as a combination of embodiments to explain the connotation of a larger range of structures or methods of the present invention.
[0022] Example 1
[0023] A spray head positioning adjustment device, such as Figure 1 , 2 As shown, the structure includes pipe section 1, pipe section 2, and expansion joint 3. Pipe section 1 and pipe section 2 form an integral structure, which is an inverted stepped tube. The upper part of the stepped tube forms a large-diameter section, and the lower part forms a small-diameter section. The large-diameter section is used to connect to the water supply pipe 4. The inner wall of the small-diameter section is provided with a threaded section 22. One end of the expansion joint is screwed to the threaded section 22. The axial length of the threaded section 22 allows the expansion joint 3 to move upward or downward along the axial direction. The other end of the expansion joint 3 extends out of the bottom of pipe section 2 through a sealing structure. The expansion joint 3 is a tubular structure, and the bottom of the expansion joint 3 is used to connect to the water inlet pipe 5 of the fire sprinkler head.
[0024] like Figure 1 , 2 As shown, the bottom of the pipe section 1 is coaxially provided with a first diameter reduction ring 12, the top end of the pipe section 2 is integrally connected to the bottom end of the first diameter reduction ring 12, the top end of the first diameter reduction ring 12 is provided with a first sealing ring 13, the inner wall of the pipe section 1 is provided with internal threads, the outer wall of the water supply pipe 4 is provided with external threads, the pipe section 1 is screwed to the water supply pipe 4, and the end of the water supply pipe 4 is tightly connected to the top end of the first sealing ring 13.
[0025] like Figure 1 , 2 As shown, the telescopic component 3 includes a tube body, and the upper end of the outer wall of the tube body is expanded to form an expansion ring 33. The expansion ring 33 is provided with external threads, and the expansion ring 33 is screwed to the threaded section 22.
[0026] like Figure 1 , 2As shown, the lower part of the pipe body forms a connecting section 31 by expanding the diameter. The connecting section 31 is provided with a second diameter reduction ring 34 in the middle. A second sealing ring 35 is installed at the lower end of the second diameter reduction ring 34. The water inlet pipe 5 of the fire sprinkler head is provided with external threads. The inner wall of the pipe body below the second diameter reduction ring 34 is provided with internal threads. The water inlet pipe 5 of the fire sprinkler head is screwed to the pipe body. The top end of the water inlet pipe 5 of the fire sprinkler head is tightly connected to the second sealing ring 35.
[0027] like Figure 1 , 2 As shown, the outer wall of the tube between the expanding ring 33 and the connecting section 31 forms a smooth rod section 32, and the bottom end of the tube section 2 is provided with a third reducing ring 23, and the smooth rod section 32 and the third reducing ring 23 are fitted with a clearance.
[0028] like Figure 1 , 2 As shown, the top end of the third reduced diameter ring 23 is provided with a third sealing ring 24, and the third sealing ring 24 is slidably connected to the smooth rod section 32.
[0029] In this embodiment, the pipe body can be rotated to make the expansion ring screwed to different positions on the threaded section, thereby adjusting the length of the pipe body extending downwards into the second pipe section.
[0030] Example 2
[0031] like Figure 1 , 2 As shown, the smooth rod section 32 is threadedly connected to the connecting section 31, and the third sealing ring 24 has several models depending on the thickness.
[0032] like Figure 1 , 2 As shown, pipe section 1 and pipe section 2 are connected by threads to form an integral structure.
[0033] This embodiment presents a novel assembled structure. Unlike Embodiment 1, this embodiment not only allows for adjustment of the fire sprinkler head height through the extension and retraction of the pipe body, but also enables adjustment of the fire sprinkler head position by changing the type of the third sealing ring. Specifically, when the fire sprinkler head reaches the preset height, the bottom end of the expansion ring can tightly abut against the third sealing ring, further improving the device's sealing performance. Simultaneously, the assembled structure facilitates the retention of functional components in the event of device damage, further reducing operating costs.
[0034] Through the above adjustments, this new invention can achieve the positioning of the fire sprinkler head by extending and retracting the telescopic component when there is a certain error in the position of the water supply pipe end, ensuring that the fire sprinkler head is installed in the preset position and at the same time meeting the requirements for sealing and pressure bearing.
