Detailed Implementation

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Example 1

[0033] This embodiment provides an adjustable angle nozzle auxiliary installation tool, including a bracket, an adjustable angle connecting assembly, and a nozzle external clamping sleeve 10; the bracket includes a fixed end 1 and a fixed rail 2; the first end of the fixed rail 2 is fixedly connected to the fixed end 1; the fixed rail 2 has a rail groove, and multiple sets of adjustment holes I3 are provided on both sides of the rail groove; the adjustable angle connecting assembly includes a sliding rail 4, a fixed sleeve 6, and a rotating sleeve 8; the sliding rail 4 is slidably engaged with the rail groove of the fixed rail 2; the sliding rail 4 is provided with an adjustment hole II5, and the adjustment hole II5 is connected to the adjustment hole I3 by bolts; the fixed sleeve 6 is fixedly connected to the second end of the sliding rail 4; the rotating sleeve 8 is rotatably connected to the fixed sleeve 6; the nozzle external clamping sleeve 10 is detachably connected to the rotating sleeve 8 and rotates with the rotating sleeve 8; the nozzle external clamping sleeve 10 is provided with a bayonet for connecting to the nozzle 100.

[0034] In the aforementioned adjustable-angle sprinkler head auxiliary installation tool, the first end of the fixed rail 2 is connected to the fixed end 1 by welding or bolting; the second end of the fixed sleeve 6 is connected to the sliding rail 4 by welding or bolting. When bolting is used, it can accommodate the wall inclination near the sprinkler head 100 on-site, meeting various on-site conditions. Before installation, it is necessary to determine the angle between the fixed rail 2 and the fixed end 1, as well as the angle between the fixed sleeve 6 and the sliding rail 4, and tighten the bolts to ensure subsequent installation at the determined angles.

[0035] In the above-mentioned adjustable angle nozzle auxiliary installation tool, adjustment hole I3 is a circular hole; adjustment hole II5 is a circular hole, and multiple holes are provided to prevent the sliding track 4 from rotating around the bolt after a single adjustment hole II5 is connected to adjustment hole I3.

[0036] In the aforementioned adjustable-angle nozzle auxiliary installation tool, the fixed sleeve 6 is evenly provided with angle scales along its circumference, ranging from 0° to 360°; the rotating sleeve 8 is provided with scale indicator lines. By cooperating with the scale indicator lines and angle scales, it is possible to quickly determine whether the installation angle of the nozzle 100 meets the installation requirements, without the need to use an angle measuring instrument.

[0037] In the aforementioned adjustable-angle nozzle auxiliary installation tool, the rotating sleeve 8 and the fixed sleeve 6 are unidirectionally rotatable via a ratchet and pawl structure 7, with a rotation direction of 0° to 360°. Reverse rotation locks the ratchet and pawl structure 7. A circular partition 6.1 is provided inside the fixed sleeve 6. The ratchet and pawl structure 7 includes a ratchet 7.1, a pawl 7.2, and a return spring 7.3. Both the ratchet 7.1 and the pawl 7.2 are rotatably mounted on the circular partition 6.1. The two ends of the return spring 7.3 are connected to the circular partition 6.1 and the pawl 7.2, respectively. The pawl 7.2 is engaged with the ratchet teeth of the ratchet 7.1 by the return spring 7.3. The rotating sleeve 8 is fixedly connected to the ratchet 7.1. The unidirectional rotation greatly facilitates the installation of the nozzle 100, which is connected by threads. The tightening direction of the bayonet and the nozzle 100 is opposite to the rotation direction of the rotating sleeve 8, which effectively prevents the nozzle 100 from loosening due to accidental tightening during the rotation of the rotating sleeve 8, greatly improving the installation accuracy and efficiency of the nozzle 100. The number of teeth on the ratchet 7.1 determines the minimum angle of rotation of the rotating sleeve 8 per turn. When the number of teeth is 72, the minimum angle of rotation of the rotating sleeve 8 per turn is 5°. The number of teeth on the ratchet 7.1 can be changed on-site according to different installation angle requirements of the nozzle 100 to meet the on-site installation needs.

[0038] For the installation of the nozzle 100 connected by a plug-in method, the inner wall of the nozzle external clamp 10 is provided with a rubber layer, which can effectively protect the nozzle 100 from scratches and improve the overall process installation quality.

[0039] In the aforementioned adjustable-angle nozzle auxiliary installation tool, the nozzle external clamp 10 and the rotating sleeve 8 are detachably connected via a quick-detachable structure 9. The quick-detachable structure 9 includes a square connector 9.1 and a square insertion hole 9.2. The square connector 9.1 is fixed to the circular end cap of the rotating sleeve 8; the square insertion hole 9.2 is located on the circular end cap of the nozzle external clamp 10. The square connector and insertion hole structure allows for quick installation and removal of the nozzle external clamp 10 and the rotating sleeve 8, accommodating nozzles of different specifications 100. It also provides circumferential restriction of the nozzle external clamp 10 relative to the rotating sleeve 8, allowing the nozzle external clamp 10 to rotate with the rotating sleeve 8. An elastic layer can be provided on the surface of the square connector 9.1 to ensure a tight connection with the square insertion hole 9.2.

[0040] In the above-mentioned adjustable angle nozzle auxiliary installation tool, the fixed rail 2 is a channel steel, the sliding rail 4 is a square steel pipe, and the fixed sleeve 6 and the rotating sleeve 8 are round steel pipes.

[0041] The specific operation process of the above-mentioned adjustable angle nozzle auxiliary installation tool is as follows:

[0042] When installing the sprinkler head 100, complete the preliminary preparations. First, determine the installation requirements of the sprinkler head 100 and the angle between the sprinkler head 100 and the wall. Based on the angle, determine the angle between the fixed end 1 and the fixed rail 2. After positioning and drilling according to the designed installation position of the sprinkler head 100, press the fixed end 1 tightly against the wall. Adjust the position of the sliding rail 4 on the fixed rail 2 so that the sprinkler head 100 meets the distance from the side wall and the ceiling. Secure the sliding rail 4 with bolts to fix the fixed end 1. Then connect the sprinkler head external clamp 10 to the sprinkler head 100. Next, connect the sprinkler head external clamp 10 to the rotating sleeve 8. According to the designed angle of the sprinkler head 100, rotate the rotating sleeve 8 until the sprinkler head 100 reaches the specified angle to complete the installation of the sprinkler head 100.

[0043] The same type of nozzle 100 has the same installation angle requirements and the same distance from the wall requirements, so only one setup is needed before the installation of subsequent nozzles 100.

[0044] If different types of nozzles 100 are used in actual operation, the nozzle external clamp 10 can be replaced according to the needs of the site, and the distance from the wall can be re-determined.

[0045] The aforementioned adjustable-angle nozzle auxiliary installation tool can accurately determine the tilt angle of the nozzle 100, greatly improving the standardization of nozzle 100 installation and avoiding the need to use an angle gauge for adjustment after each nozzle 100 installation, thus greatly improving the installation efficiency of the nozzle 100.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
