Description

Technical Field

[0001] The invention relates to the field of fire protection system components, and in particular to an adjustable quick-install device and method for concealed sprinkler. Background Art

[0002] At present, the fire protection pipes in buildings are all pre-installed. After the main pipe of the fire protection pipe is arranged, branch pipes are connected from the main pipe to each room, and then sprinkler heads are installed at the relative positions of the branch pipes.

[0003] A Chinese patent (publication number CN118110843A) discloses a screw-type quick-install center fastener. When encountering an installation scenario without a keel, a screw is fixed on the roof according to the installation position, and the other end is inserted into the threaded hole of the screw-type quick-install center fastener, and then fixed with a nut, so that the screw-type quick-install fastener is hoisted on the screw, and then the water outlet pipe of the fire hose is inserted into the pipe fixing hole formed by the first fastener and the second fastener of the screw-type quick-install center fastener, and the position is adjusted to fix it, and the fire hose is installed; if a narrow installation scenario is encountered where a square tube or a bracket cannot be installed for fixing, after finding a suitable installation position for the water outlet pipe, first fix the screw-type quick-install center fastener on the roof through the installation holes at both ends of the screw-type quick-install center fastener, and then insert the water outlet pipe of the fire hose into the pipe fixing hole formed by the first fastener and the second fastener of the screw-type quick-install center fastener, so that the fire hose can be used normally. When the sprinkler head structure of the fire protection pipeline is installed in an environment with a keel, it is inconvenient to fix the above-mentioned fasteners on the square tube, bracket and other positions of the keel. In addition, the existing fasteners have a small movable space when installed on the square tube and are not easy to install. After installation, they are easy to slide due to the large space. When the fasteners are installed, the fasteners and buckle plates generally have a large movable stroke, and both hands are required for clamping. The installation is complicated, which affects the installation efficiency and stability of the concealed sprinkler head after installation. Summary of the invention

DETAILED DESCRIPTION

[0030] Example 1

[0031] In a typical embodiment of the present invention, Figure 1-Figure 3 As shown, an adjustable quick-install device for concealed spraying is provided.

[0032] The screw-type quick-install center fastener in the prior art is mainly used for the installation of fire hoses, especially in installation scenarios without keels or in narrow spaces. However, in an environment with a keel, the fastener is not easy to install due to its small movable space, and it is easy to slide after installation due to the large space. In addition, the fixing method of the existing fastener is not flexible enough to meet various installation requirements. Based on this, this embodiment proposes an adjustable quick-install device for concealed sprinklers, providing a more flexible, easy-to-install and stable fastener solution.

[0033] like Figure 1 As shown, the adjustable quick-install device 1 for concealed sprinkler is applied to the layout of fire protection pipelines, and can fix the water outlet pipe 2 on the fixing rod 3, so as to facilitate the installation of the concealed sprinkler head 4 at the end of the water outlet pipe 2, thereby realizing the concealed sprinkler layout. Figure 2 As shown, the adjustable quick-install device 1 for concealed spraying mainly includes a first fastener 5 and a second fastener 6. The first fastener 5 and the second fastener 6 are both concave channel steel structures. The first fastener 5 and the second fastener 6 are rotatably connected through a pin shaft 12. The first fastener 5 can cooperate with the fixing rod 3 of the external keel. The first fastener 5 and the second fastener 6 can hold and clamp the water outlet pipe 2 in the buckled state. The first fastener 5 is equipped with a threaded rod 10, and the second fastener 6 is provided with a guide inclined surface 14 that cooperates with the threaded rod 10 to form an adjustment component. When the first fastener 5 and the second fastener 6 cooperate to form a buckled state, the threaded rod 10 on the first fastener 5 can adjust the axial position by rotation to abut against the guide inclined surface 14, thereby pushing the guide inclined surface 14 to move to drive the second fastener 6 to rotate relative to the first fastener 5, changing the clamping state of the first fastener 5 and the second fastener 6, and achieving the clamping of the water outlet pipe 2 and locking the position on the fixing rod 3.

[0034] like Figure 2As shown, the first fastener 5 is provided with a first through slot for the fixing rod 3 to pass through, one side of the first through slot is closed, and the other side forms a side opening, and the side opening is arranged opposite to the second fastener 6; both ends of the first through slot are open, and when the first fastener 5 and the second fastener 6 are not clamped, a sliding fit is formed between the first through slot and the fixing rod 3, and the position of the first fastener 5 relative to the fixing rod 3 is adjusted by sliding. Figure 1 As shown, the fixing rod 3 can be a beam, a square tube, etc. in the keel system, which is horizontally distributed, inclined, or vertically distributed. By using the cooperation of the first fastener 5 and the second fastener 6, the entire adjustable quick-install device 1 for concealed sprinkler can be stably installed on the fixing rod 3.

[0035] A first groove 9 for accommodating the water outlet pipe 2 is provided on the side plate 11 of the first fastener 5, and the first groove 9 extends to a side opening. After the water outlet pipe 2 is connected to the sprinkler head 4, it can be inserted into the first groove 9 from an opening position on one side of the first groove 9. When the water outlet pipe 2 is not connected to the sprinkler head 4, it can also be inserted from one side of the first groove 9. A threaded rod 10 is threadedly matched on the side plate 11 of the first fastener 5 for matching with the guide ramp 14 to achieve adjustment.

[0036] like Figure 2 As shown, one end of the second fastener 6 is rotatably connected to the first fastener 5, and the rotatable connection can be achieved by using a pin shaft 12, and the other end of the second fastener 6 is provided with a guide inclined surface 14 that is inclined relative to the axis of the threaded rod 10. It can be understood that the second fastener 6 is a groove plate type structure, with a pin shaft 12 installed at one end along the length direction and a guide inclined surface 14 provided at the other end.

[0037] After the first fastener 5 cooperates with the second fastener 6, the guide slope 14 can be pushed into the first through groove by rotation. At this time, the second fastener 6 cooperates with the first fastener 5 to embrace and block the opening of the first groove 9, thereby realizing the constraint on the position of the water outlet pipe 2 in the first groove 9.

[0038] One end of the threaded rod 10 abuts against the guiding inclined surface 14 . When the threaded rod 10 is driven to rotate, the guiding inclined surface 14 is pushed to drive the second fastener 6 to rotate relative to the first fastener 5 , thereby adjusting the tightness of the clamping space 21 .

[0039] By adjusting the relative position of the threaded rod 10 and the first fastener 5 in the axial direction, the relative rotation angle of the first fastener 5 and the second fastener 6 can be changed, thereby adjusting the tightness of the clamping space 21. This makes the fastener more flexible during installation, and the locking effect of the threaded rod 10 can be used to achieve stable fixation. The locking effect of the threaded rod 10 can ensure the stability of the fastener after installation. At the same time, since the first groove 9 is connected to the first through groove, when the second fastener 6 cooperates with the first fastener 5 to clamp the water outlet pipe 2, the water outlet pipe 2 segment in the first through groove will also push the fixing rod 3 in the first through groove, so that the fixing rod 3 is clamped and fixed, thereby preventing sliding due to the large space.

[0040] After the first fastener 5 and the second fastener 6 are fastened together, the fasteners can be installed and clamped by adjusting the threaded rod 10 without the need for two-handed operation, which greatly simplifies the installation process and improves the installation efficiency.

[0041] like Figure 3 As shown, the first through slot is a variable cross-section slot, including a slide slot 7 near the closed side of the first through slot and a receiving slot 8 near the side opening. The slide slot 7 and the receiving slot 8 are distributed in sequence from the closed side to the side opening of the first through slot. The slide slot 7 is a portion near the closed side of the first through slot, and is used to fit the fixing rod 3 to pass through. The size and shape of the slide slot 7 match the fixing rod 3, ensuring that the fixing rod 3 can be firmly inserted into and fixed in the slide slot 7.

[0042] The receiving groove 8 is a portion of the first through groove close to the side opening. In the direction of the line connecting the two side plates 11 of the first fastener 5, the thickness of the receiving groove 8 is greater than the thickness of the slide groove 7. The receiving groove 8 is used to match the second fastener 6 and the water outlet pipe 2. The two side plates 11 of the first fastener 5 corresponding to the receiving groove 8 are respectively provided with first grooves 9. The two first grooves 9 cooperate with the second fastener 6 to form a clamping space 21 for clamping the water outlet pipe 2.

[0043] Along the direction of the line connecting the two side plates 11 of the first fastener 5, the thickness of the accommodating groove 8 is greater than the thickness of the sliding groove 7, and a bending transition is formed between the accommodating groove 8 and the sliding groove 7. When in use, the fixing rod 3 can be first inserted into the thicker accommodating groove 8, and then pushed into the sliding groove 7 through the bending transition, thereby improving the installation efficiency, ensuring that the sliding groove 7 is firmly matched with the fixing rod 3, and providing sufficient space to accommodate and clamp the water outlet pipe 2 and the second fastener 6.

[0044] like Figure 2 and Figure 3 As shown, the cross-sections of the first fastener 5 and the second fastener 6 are both concave-shaped, and are grooved plate structures, so that the first fastener 5 and the second fastener 6 can partially overlap, and the second fastener 6 can be buckled outside the first fastener 5 and fit tightly to form a stable clamping structure.

[0045] The side surface of the second fastener 6 is an ear plate 19, and the ear plate 19 and the side plate 11 of the first fastener 5 are provided with a snap-fit ​​assembly at the overlapping position for temporarily fixing the first fastener 5 and the second fastener 6 to facilitate installation and adjustment.

[0046] In this embodiment, the clamping assembly can adopt a matching structure of a protrusion 17 and a recess 18, the protrusion 17 is arranged on the side plate 11 of the first fastener 5, and the recess 18 is arranged on the ear plate 19 of the second fastener 6. In the overlapping position, the protrusion 17 is embedded in the recess 18 to form a preliminary fixation, and can be disengaged under external force to form a temporary clamping state. In other optional embodiments, other forms can also be adopted, such as elastic retaining beads matching grooves, etc.

[0047] The snap-fit ​​components are distributed on the side plate 11 of the first fastener 5 and the ear plate 19 on one side of the second fastener 6, and are used to temporarily fix the positions of the first fastener 5 and the second fastener 6 during the adjustment process to prevent them from being accidentally separated.

[0048] In addition, if Figure 3 As shown, a stopper 15 is also formed on the ear plate 19 of the second fastener 6. The stopper 15 is U-shaped and can abut against the threaded rod 10, thereby constraining the relative position of the first fastener 5 and the second fastener 6, avoiding excessive clamping between the first fastener 5 and the second fastener 6, and constraining the maximum clamping position of the first fastener 5 and the second fastener 6 in the locked state.

[0049] The guide slope 14 is located between the ear plates 19 on both sides of the second fastener 6. Figure 3 As shown, the guiding inclined surface 14 is formed by bending the bottom plate of the second fastener 6, and a groove structure may be adopted, and a guiding section is formed in the groove.

[0050] The axis of the threaded rod 10 is parallel to the rotation axis of the first fastener 5 relative to the second fastener 6 , so that the threaded rod 10 can smoothly push the guiding inclined surface 14 when rotating, thereby driving the second fastener 6 to rotate relative to the first fastener 5 .

[0051] The ear plate 19 is provided with second grooves 13, which are engaged with the first grooves 9 on the first fastener 5 to form a clamping space 21 for clamping the water outlet pipe 2. This ensures that the water outlet pipe 2 is firmly clamped between the fasteners and is not easy to loosen.

[0052] The side plate 11 is provided with a threaded hole 16, one end of the threaded rod 10 passes through the threaded hole 16 and abuts against the guide inclined surface 14, and the other end is an operating end. By rotating the operating end, the axial position of the threaded rod 10 can be adjusted, thereby changing the relative rotation angle of the first fastener 5 and the second fastener 6 and the tightness of the clamping space 21.

[0053] Through the design of the variable cross-section groove, the cooperation between the clamping assembly and the stopper 15, and the adjustable threaded rod 10, this embodiment provides greater installation flexibility and adaptability, and can meet the installation requirements in different scenarios. Through the stable clamping structure and the locking effect of the threaded rod 10, this embodiment ensures the stability and reliability of the fastener after installation, and prevents safety hazards caused by loosening or sliding. The installation and clamping of the fastener can be achieved through a simple rotation operation, without the need for complicated tools and steps, which greatly simplifies the installation process. It is suitable for a variety of installation scenarios and different types of water outlet pipes 2, and has high versatility and applicability.

[0054] In addition, a toggle plate 20 is provided on the ear plate 19 of the second fastener 6 for easy operation. The toggle plate 20 is formed by bending and extending the ear plate 19 and protruding from the ear plate 19 to facilitate operation when pushing the second fastener 6 to cooperate with the first fastener 5 or to separate from the first fastener 5.

[0055] A threaded hole 16 is provided on the side panel 11, and one end of the threaded rod 10 passes through the threaded hole 16 to abut and push the guide ramp 14, and the other end is the operating end. The operating end can adopt a hexagonal head, a hexagonal head, a slot or a cross slot, etc., which is convenient for the cooperation of external operating tools and improves the installation efficiency.

[0058] A working method of an adjustable quick-install device for concealed spraying, comprising:

[0059] The first fastener 5 and the second fastener 6 rotate to open the first groove 9, and the external fixing rod 3 passes through the first through groove;

[0060] The water outlet pipe 2 enters the first groove 9 from the side opening of the first through groove, and the second fastener 6 rotates to block the first groove 9, so that the water outlet pipe 2 is constrained in the first groove 9;

[0061] The guiding inclined surface 14 rotates along with the second fastener 6. After the end of the guiding inclined surface 14 close to the threaded rod 10 passes over the threaded rod 10, the threaded rod 10 is rotated so that the threaded rod 10 abuts against the guiding inclined surface 14.

[0062] The threaded rod 10 is adjusted to drive the second fastener 6 to rotate relative to the first fastener 5 to clamp the water outlet pipe 2 and fix the water outlet pipe 2 on the fixing rod 3 .

[0063] When the second fastener 6 and the first fastener 5 clamp the water outlet pipe 2 , the water outlet pipe 2 pushes the fixing rod 3 to fit the closed side of the first through groove, and the first fastener 5 and the second fastener 6 clamp the fixing rod 3 and the water outlet pipe 2 together.

[0064] The fastener structure of this embodiment is suitable for various installation scenarios and different types of water outlet pipes 2, and has high versatility and applicability, so that the fastener can be widely used in various fields such as water conservancy, construction and agriculture, thereby improving the market competitiveness of the product.

[0065] By optimizing the structural design and installation process of the fasteners, this embodiment significantly improves the installation efficiency and quality, not only reduces the installation difficulty and cost, but also improves the stability and reliability of the system.

[0066] The stable clamping structure and the locking effect of the threaded rod 10 ensure the stability and reliability of the fastener after installation, thereby enhancing the safety of the system, effectively preventing safety hazards caused by loosening or sliding, and improving the overall performance and safety of the system.
