Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to an installation device for a variable diameter fire sprinkler head. Background Technology

[0002] Fire sprinkler heads are typically installed on walls or ceilings and connected to pressurized water pipes. In the event of a fire, water is sprayed through the sprinkler heads to extinguish the fire and limit the generation of toxic fumes. With the continuous advancement of fire protection system technology, higher requirements have been placed on the design of fire protection equipment. Traditional fixed-diameter fire sprinkler heads have gradually evolved into variable-diameter fire sprinkler heads. Variable-diameter fire sprinkler heads are formed by connecting the sprinkler head with a reducing joint or by directly molding the reducing joint and the sprinkler head into one piece during the manufacturing process. The reducing joint can increase the diameter of the sprinkler head, allowing the sprinkler head to connect to fire pipes with larger diameters, thereby increasing the water pressure while ensuring the water supply and improving the sprinkler effect.

[0003] The installation of reducing fire sprinkler heads is usually done with pipe wrenches. However, the size and shape of the reducing section of the reducing fire sprinkler head limit the flexibility of the pipe wrench operation, increasing the difficulty and time required for the operation. During the installation process, the pipe wrench is prone to slipping, making it difficult to effectively fix the reducing fire sprinkler head, resulting in low installation efficiency.

[0010] Preferably, the first end of the first mounting part is provided with multiple sets of limiting grooves in the circumferential direction, each set including two limiting grooves, and the two limiting grooves in each set are arranged in the same radial direction of the first mounting part.

[0011] Preferably, the limiting groove connects the inner wall and the outer wall of the first mounting part, or the limiting groove is disposed on the inner wall of the first mounting part.

[0012] Preferably, the first mounting part is provided with a plurality of connecting holes in the circumferential direction, the connecting holes and the limiting grooves are staggered, and an adjusting screw is inserted into each connecting hole, the adjusting screw being provided with a scale.

[0013] Preferably, in the receiving groove of the first mounting part, a boss with a bevel or arc surface is formed on the side wall of the receiving groove near the first end of the first mounting part.

[0014] Preferably, the width of the limiting groove is not less than the thickness of the protrusion on the reducing joint of the reducing fire sprinkler head, and the depth of the limiting groove is not less than the height of the reducing joint of the reducing fire sprinkler head.

[0016] In summary, by adopting the above technical solution, this utility model has at least the following beneficial effects:

[0017] By setting up a first mounting part and a second mounting part, and setting a receiving groove and a limiting groove on the first mounting part, after the variable diameter fire sprinkler head is placed in the receiving groove, the protrusion of the variable diameter joint is locked into the limiting groove, which can prevent the variable diameter fire sprinkler head from slipping in the receiving groove and improve the installation efficiency of the variable diameter fire sprinkler head. By setting a connecting groove on the second mounting part, the drive shaft of the electric wrench can be inserted into the connecting groove, and the installation efficiency of the variable diameter fire sprinkler head can be further accelerated by using the electric wrench. By setting an adjusting screw on the first mounting part, when there is a gap between the surface of the variable diameter joint of the variable diameter fire sprinkler head and the receiving groove, the adjusting screw can be pressed against the variable diameter joint to prevent the variable diameter joint from slipping relative to the first mounting part. Multiple sizes of variable diameter fire sprinkler heads can also be installed in the same first mounting part, improving the installation flexibility. During use, the position of the adjusting screw can be precisely adjusted by the scale on it to prevent the variable diameter fire sprinkler head from being misaligned, which would affect the docking and installation of the variable diameter fire sprinkler head.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so that the purpose, technical solution and advantages of the present invention will be clearer. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Figure 1 An exemplary embodiment of the present invention is shown, which is an installation device for a variable diameter fire sprinkler head. The installation device for the variable diameter fire sprinkler head includes a first installation part 1 and a second installation part 2 arranged coaxially. The first end of the first installation part 1 is axially provided with a receiving groove 11 for accommodating the variable diameter fire sprinkler head. The first installation part 1 is also axially provided with a limiting groove 12 for limiting the variable diameter fire sprinkler head. The limiting groove 12 extends from the first end of the first installation part 1 toward the second end of the first installation part 1 (the first end and the second end of the first installation part are opposite to each other, and the first end and the second end of the second installation part are opposite to each other). The second end of the first installation part 1 is connected to the first end of the second installation part 2.

[0028] After the receiving groove 11 accommodates the variable diameter fire sprinkler head, the first mounting part 1 can effectively clamp the variable diameter fire sprinkler head under the action of the limiting groove 12. During the rotation of the variable diameter fire sprinkler head driven by the first mounting part 1, the variable diameter fire sprinkler head can be effectively prevented from slipping relative to the first mounting part 1, thereby improving the installation efficiency of the variable diameter fire sprinkler head.

[0029] refer to Figure 2 , Figure 6 , Figure 7 The second end of the second mounting part 2 is provided with a connecting groove 21 in the axial direction. During use, a T-shaped wrench can be inserted into the connecting groove 21 to speed up the installation efficiency of the variable diameter fire sprinkler head, or an electric wrench can be inserted into the connecting groove 21 to further speed up the installation efficiency of the variable diameter fire sprinkler head.

[0030] A magnet is installed inside the connecting groove 21. The magnet can be located at the bottom of the connecting groove 21, or magnetic material can be installed on the bottom and side walls of the connecting groove 21. The magnet or magnetic material can attract the drive shaft of the T-wrench or electric wrench into the connecting groove 21, further improving the installation efficiency of the variable diameter fire sprinkler head. Furthermore, the width of the connecting groove 21 is adapted to the drive shaft of the T-wrench or electric wrench, and the depth of the connecting groove 21 is not less than 25mm.

[0031] Both the first mounting part 1 and the second mounting part 2 are made of steel. The first mounting part 1 and the second mounting part 2 are integrally formed or welded, which can ensure the connection stability of the first mounting part 1 and the second mounting part 2. During the installation of the variable diameter fire sprinkler head, the reliability of the installation device structure used for the variable diameter fire sprinkler head can be guaranteed.

[0032] During application, a limiting groove 12 can be provided only on the first mounting part 1, through which the protrusion 4 (see reference) on the reducing joint 31 of the reducing diameter fire sprinkler head 3 is positioned. Figure 5 ( ) Limiting; Alternatively, a set of limiting grooves 12 can be provided on the first mounting part 1. This set of limiting grooves 12 includes two limiting grooves 12, which are arranged in the same radial direction of the first mounting part 1. The two limiting grooves 12 are symmetrically arranged, which can improve the balance of the variable diameter fire sprinkler head in the receiving groove 11 when installing the variable diameter fire sprinkler head. More sets of limiting grooves 12 can also be provided circumferentially on the first mounting part 1. Each set includes two limiting grooves 12, which are arranged in the same radial direction of the first mounting part 1. The two limiting grooves 12 are symmetrically arranged, and the angle between adjacent sets of limiting grooves 12 is determined according to the position of the protrusion line 4 on the variable diameter joint 31. Setting multiple sets of limiting grooves 12 can further improve the stability of the variable diameter fire sprinkler head and prevent the variable diameter fire sprinkler head from slipping during installation.

[0033] The limiting groove 12 can be provided on the inner wall of the first mounting part 1. When it is provided on the inner wall of the first mounting part 1, a groove can be provided on the inner wall to form the limiting groove; or one or more sets of strip-shaped protrusions can be provided on the inner wall of the first mounting part 1 (see reference). Figure 3 Each set of strip-shaped protrusions is axially arranged, and each set of strip-shaped protrusions includes two strip-shaped spacers, with a limiting groove 12 formed between the two strip-shaped spacers. The limiting groove 12 can also connect the inner wall and the outer wall of the first mounting part 1. When the limiting groove 12 connects the inner wall and the outer wall of the first mounting part 1, the protrusion width d of the protrusion line 4 of the reducing joint 31 can be increased (refer to...). Figure 5 The raised line 4 has a rectangular cross-section, which confines it within the limiting groove 12, improving the stability of the connection between the variable diameter fire sprinkler head and the first mounting part 1. Furthermore, the width of the limiting groove 12 is not less than the thickness of the raised line 4 on the variable diameter connector 31 of the variable diameter fire sprinkler head, and the depth of the limiting groove 12 is not less than the height of the variable diameter connector 31 of the variable diameter fire sprinkler head, so that the raised line 4 is stably engaged within the limiting groove 12, preventing the variable diameter fire sprinkler head from rotating relative to the first mounting part 1, reducing the installation time of the variable diameter fire sprinkler head. The bottom of the limiting groove 12 can contact the raised line 4, stably supporting the variable diameter fire sprinkler head. The depth of the receiving groove 11 is not less than the height of the variable diameter fire sprinkler head, and the width of the receiving groove 11 is not less than the diameter of the variable diameter connector 31 of the variable diameter fire sprinkler head.

[0034] During application, multiple connecting holes can be circumferentially arranged on the first mounting part 1. When the first mounting part 1 is provided with a limiting groove 12, the connecting holes and the limiting groove 12 are staggered. An adjusting screw 6 is inserted into each connecting hole (see reference). Figure 4 , Figure 5 The adjusting screw 6 has a scale. After the variable diameter fire sprinkler head is placed in the receiving groove 11, when there is a gap between the variable diameter fire sprinkler head and the receiving groove 11, the adjusting screw 6 can be used to press against the variable diameter joint 31 of the variable diameter fire sprinkler head to prevent the variable diameter joint 31 from slipping relative to the first mounting part 1. This structure can also install multiple sizes of variable diameter fire sprinkler heads through the same first mounting part 1, improving the flexibility of installation. During use, the position of the adjusting screw 6 can be precisely adjusted through the scale on it to prevent the variable diameter fire sprinkler head from being tilted, which would affect the docking and installation of the variable diameter fire sprinkler head.

[0035] In the receiving groove 11 of the first mounting part 1, a boss 13 with a sloping or arc surface is formed on the side wall of the receiving groove 11 near the first end of the first mounting part 1. After the variable diameter fire sprinkler head is placed into the receiving groove 11, the variable diameter part of the variable diameter connector 31 contacts the boss 13, which can support the variable diameter connector 31 of the variable diameter fire sprinkler head and improve the stability of the variable diameter fire sprinkler head in the receiving groove 11. The boss 13 can be used in conjunction with the limiting groove 12 and / or the adjusting screw 6.

[0036] refer to Figure 5 , Figure 7 The variable diameter fire sprinkler head 3 includes a variable diameter connector 31 and a sprinkler head 32, which are connected. The installation method of the variable diameter fire sprinkler head 3 is as follows: the variable diameter fire sprinkler head 3 is placed into the receiving groove 11 of the first mounting part 1, so that the protrusion 4 of the variable diameter connector 31 is engaged in the limiting groove 12, the flange 5 at the top of the variable diameter connector 31 contacts the first end surface of the first mounting part 1, and the flange 5 extends out of the first mounting part 1, so that the first mounting part 1 supports the flange 5. Then, the drive shaft of the T-wrench or electric wrench is inserted into the connecting groove 21 of the second mounting part 2. During the rotation of the T-wrench or electric wrench, the installation device for the variable diameter fire sprinkler head drives the fire sprinkler head to rotate together to install the variable diameter fire sprinkler head 3.
