Description

Technical Field

[0001] This utility model relates to the field of fire sprinkler technology, specifically to a telescopic fire sprinkler. Background Technology

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head's splash plate to extinguish the fire. Currently, they are divided into pendant sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, and sidewall sprinkler heads.

[0003] A search revealed that publication number CN211097220U discloses a telescopic fire sprinkler head, including a pipe body. One end of the pipe body is provided with a connecting flange, and the other end is connected to the pipe body and provided with a conical sprinkler head. The pipe body is configured as a telescopic structure, which includes a fixed pipe. A telescopic pipe is inserted into and slidably connected to the fixed pipe. The connecting flange is located at the end of the fixed pipe away from the telescopic pipe. The conical sprinkler head is connected to the end of the telescopic pipe away from the fixed pipe. A driving component is provided on the fixed pipe for driving the telescopic pipe to move within the fixed pipe. The operator holds the pipe body and drives the telescopic pipe to move within the fixed pipe through the driving component, so that the telescopic pipe drives the conical sprinkler head towards the root of the flame. The driving component is located on the fixed pipe, allowing the operator to drive the conical sprinkler head towards the flame from a position away from the root of the flame. This allows the sprinkler head to achieve better fire extinguishing effect while preventing operators from being injured due to being too close to the flames. However, its drawback lies in the following: When adjusting the position of the conical sprinkler head, the handle drives the second bevel gear to mesh with the first spur gear, causing the second bevel gear to rotate the screw. This causes the sleeve to move on the screw, which in turn moves the telescopic tube within the fixed tube, thus displacing the conical sprinkler head. When the conical sprinkler head reaches the designated position, the device lacks a fixing mechanism to secure it, making it difficult to fix after length adjustment and affecting fire extinguishing efficiency. Therefore, improving existing fire sprinkler heads and designing a new type of telescopic fire sprinkler head to address these technical shortcomings and improve the overall practicality of fire sprinkler heads is particularly important. Utility Model Content

[0004] The purpose of this utility model is to provide a telescopic fire sprinkler head that limits the position of the connecting sprinkler head, thereby facilitating its fixation. This solves the problem that existing telescopic fire sprinkler heads are difficult to fix, leading to difficulties in fixing them after length adjustment and affecting fire extinguishing efficiency. Furthermore, when the connecting sprinkler head is not in use, the closing component can close it, preventing dust from clogging the sprinkler head when it is not in use for extended periods, thus addressing the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A telescopic fire sprinkler head includes a pipe body, a telescopic tube slidably connected inside the pipe body, a connecting shell on the outside of the pipe body, a limiting component inside the connecting shell, a transmission rod rotatably connected to the front end inside the connecting shell, a first bevel gear fixedly connected to the outside of the transmission rod, a second bevel gear meshing with the outside of the first bevel gear, a first screw fixedly connected inside the second bevel gear, a movable frame threadedly connected to the outside of the first screw, the movable frame being fixedly connected to the telescopic tube, a connecting sprinkler head fixedly connected to the end of the telescopic tube away from the pipe body, and a closing component at the end of the connecting sprinkler head away from the telescopic tube.

[0007] The limiting assembly is used to limit the transmission rod. The limiting assembly consists of a limiting gear, a limiting block, a connecting cylinder, a connecting seat, and a second screw. The limiting gear is fixedly connected to the middle of the transmission rod. The limiting block is located outside the limiting gear. The connecting cylinder is fixedly connected to the end of the limiting block away from the limiting gear. The connecting seat is fixedly connected to the bottom end inside the connecting shell. The second screw is rotatably connected to the end of the connecting seat near the limiting block.

[0008] The closing assembly is used to close the connected nozzle.

[0009] As a preferred embodiment of this utility model, the internal structure size of the limiting gear is designed to correspond to the external structure size of the limiting block, and the limiting block and the limiting gear are connected in a limiting manner.

[0010] As a preferred embodiment of this utility model, two sets of sliding rods are fixedly connected to one end of the limiting block near the connecting seat, and the sliding rods are slidably connected to the connecting seat.

[0011] As a preferred embodiment of this utility model, the second screw extends into the interior of the connecting seat and is fixedly connected to a third bevel gear, the outer side of the third bevel gear is meshed with a fourth bevel gear, and the interior of the fourth bevel gear is fixedly connected to a drive rod.

[0012] As a preferred embodiment of this utility model, a guide frame is fixedly connected to one end of the pipe body near the movable frame, and the movable frame is connected to the guide frame through a connecting frame, wherein the connecting frame and the guide frame are slidably connected.

[0013] As a preferred embodiment of this utility model, the closing assembly consists of a sleeve, multiple sets of closing blocks, and a rotating disk. The sleeve is fixedly connected to the end of the connecting nozzle away from the telescopic tube. The multiple sets of closing blocks are slidably connected to the end of the sleeve away from the connecting nozzle. The rotating disk is rotatably connected to the end of the sleeve away from the connecting nozzle and is located outside the multiple sets of closing blocks.

[0014] As a preferred embodiment of this utility model, the rotating disk has an arc-shaped groove inside, the closing block is slidably connected to the arc-shaped groove, and the sleeve has multiple sets of sliding grooves at one end near the rotating disk, with the closing block slidably connected to the sliding grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, through the design of the limiting component, when the connected nozzle is displaced to the designated position, the rotating drive rod drives the fourth bevel gear to rotate, causing the third bevel gear to rotate, which in turn drives the second screw to move, causing the limiting block to move and connect with the limiting gear to limit the transmission rod, preventing the transmission rod from rotating, thereby preventing the first screw from rotating. Therefore, the telescopic tube and the position of the connected nozzle can be limited, achieving the purpose of easy fixation. This solves the problem that existing telescopic fire sprinklers are inconvenient to fix, making it difficult to fix after length adjustment during use, thus affecting fire extinguishing efficiency.

[0017] 2. In this utility model, through the design of the closing component, when the connected sprinkler head is not in use, rotating the rotating disk drives the closing block to move through the arc groove, so that multiple sets of closing blocks can contact each other, thereby closing the sleeve. This solves the problem that when the fire sprinkler head is not used for a long time, dust in the air will block the sprinkler head, thus preventing it from being used normally when needed.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A telescopic fire sprinkler head includes a pipe body 1, a telescopic tube 2 slidably connected inside the pipe body 1, a connecting shell 3 on the outside of the pipe body 1, a limiting component 4 inside the connecting shell 3, a transmission rod 5 rotatably connected to the front end inside the connecting shell 3, a first bevel gear 6 fixedly connected to the outside of the transmission rod 5, a second bevel gear 7 meshing with the outside of the first bevel gear 6, a first screw 8 fixedly connected inside the second bevel gear 7, a movable frame 9 threadedly connected to the outside of the first screw 8, the movable frame 9 being fixedly connected to the telescopic tube 2, a connecting sprinkler head 10 fixedly connected to the end of the telescopic tube 2 away from the pipe body 1, and a closing component 11 provided at the end of the connecting sprinkler head 10 away from the telescopic tube 2.

[0028] The limiting component 4 is used to limit the transmission rod 5. The limiting component 4 consists of a limiting gear 12, a limiting block 13, a connecting cylinder 14, a connecting seat 15, and a second screw 16. The limiting gear 12 is fixedly connected to the middle of the transmission rod 5. The limiting block 13 is located outside the limiting gear 12. The connecting cylinder 14 is fixedly connected to the end of the limiting block 13 away from the limiting gear 12. The connecting seat 15 is fixedly connected to the bottom end inside the connecting shell 3. The second screw 16 is rotatably connected to the end of the connecting seat 15 near the limiting block 13.

[0029] The closing component 11 is used to close the connecting nozzle 10.

[0030] Furthermore, the internal structure size of the limiting gear 12 corresponds to the external structure size of the limiting block 13. The limiting block 13 and the limiting gear 12 are connected in a limiting manner. Two sets of sliding rods 17 are fixedly connected to one end of the limiting block 13 near the connecting seat 15. The sliding rods 17 are slidably connected to the connecting seat 15. The limiting block 13 and the limiting gear 12 are meshed together, so that the limiting block 13 and the limiting gear 12 can limit the transmission rod 5, preventing the transmission rod 5 from rotating. The sliding rods 17 are slidably connected to the connecting seat 15. When the limiting block 13 is displaced, the sliding rods 17 can guide it to prevent deviation.

[0031] The second screw 16 extends into the interior of the connecting seat 15 and is fixedly connected to a third bevel gear 18. The outer side of the third bevel gear 18 is meshed with a fourth bevel gear 19. The interior of the fourth bevel gear 19 is fixedly connected to a drive rod 20. Rotating the drive rod 20 causes the fourth bevel gear 19 to rotate, which in turn causes the third bevel gear 18 to rotate, which in turn causes the second screw 16 to move, causing the limiting block 13 to move and connect with the limiting gear 12 to limit the transmission rod 5.

[0032] Secondly, a guide frame 21 is fixedly connected to one end of the main pipe 1 near the movable frame 9. The movable frame 9 is connected to the guide frame 21 through a connecting frame 22. The connecting frame 22 and the guide frame 21 are slidably connected. Rotating the transmission rod 5 drives the first bevel gear 6 to rotate, causing the second bevel gear 7 to rotate, which in turn drives the first screw 8 to rotate, causing the movable frame 9 to move and the telescopic pipe 2 to move. This causes the connecting nozzle 10 to move towards the root of the flame, and prevents the operator's hands from getting too close to the flame and causing injury. When the movable frame 9 moves, it drives the connecting frame 22 to move. The guide frame 21 guides the connecting frame 22, allowing the movable frame 9 to move stably.

[0033] Furthermore, the closing assembly 11 consists of a sleeve 23, multiple sets of closing blocks 24, and a rotating disk 25. The sleeve 23 is fixedly connected to the end of the connecting nozzle 10 away from the telescopic pipe 2. The multiple sets of closing blocks 24 are all slidably connected to the end of the sleeve 23 away from the connecting nozzle 10. The rotating disk 25 is rotatably connected to the end of the sleeve 23 away from the connecting nozzle 10 and is located outside the multiple sets of closing blocks 24. When the connecting nozzle 10 is not in use, the closing assembly 11 can close the connecting nozzle 10, solving the problem that dust in the air will block the nozzle when the fire sprinkler is not used for a long time, thus preventing the fire sprinkler from being used normally when needed.

[0034] Furthermore, the rotating disk 25 has an arc-shaped groove 26 inside, and the closing block 24 is slidably connected to the arc-shaped groove 26. The sleeve 23 has multiple sets of sliding grooves 27 at one end near the rotating disk 25, and the closing block 24 is slidably connected to the sliding grooves 27. Rotating the rotating disk 25 drives the closing block 24 to move through the arc-shaped groove 26, so that the multiple sets of closing blocks 24 can contact each other, thereby closing the sleeve 23. When the closing block 24 moves, the sliding groove 27 can guide the closing block 24, so that the closing block 24 can move stably.

[0035] In this embodiment, the specific implementation scenario is as follows: In actual use, rotating the transmission rod 5 drives the first bevel gear 6 to rotate, causing the second bevel gear 7 to rotate, which in turn drives the first screw 8 to rotate, causing the moving frame 9 to shift, which in turn drives the telescopic tube 2 to shift, thereby causing the connecting nozzle 10 to shift towards the root of the flame. This prevents the operator's hands from getting too close to the flame and causing injury. When the connecting nozzle 10 shifts to the designated position, rotating the drive rod 20 drives the fourth bevel gear 19 to rotate, causing the third bevel gear 18 to rotate, which in turn drives the second screw 16 to shift, causing the limiting block 13 to shift and connect with the limiting gear 12 to limit the transmission rod 5, preventing the transmission rod 5 from rotating. This prevents the first screw 8 from rotating, thus limiting the telescopic tube 2 and the position of the connecting nozzle 10. This design achieves the goal of easy fixing, solving the problem of inconvenient fixing of existing telescopic fire sprinklers, which makes it difficult to fix after length adjustment during use, thus affecting fire extinguishing efficiency. When the connected sprinkler head 10 is not in use, rotating the rotating disk 25 drives the closing block 24 to move through the arc groove 26, allowing multiple sets of closing blocks 24 to contact each other, thereby closing the sleeve 23. This solves the problem that dust in the air will block the sprinkler head when it is not used for a long time, thus preventing it from working properly when needed. Compared with existing fire sprinklers, this design achieves the goal of easy fixing, solving the problem of inconvenient fixing of existing telescopic fire sprinklers, which makes it difficult to fix after length adjustment during use, thus affecting fire extinguishing efficiency, and solving the problem of dust in the air blocking the sprinkler head when it is not used for a long time, thus preventing it from working properly when needed.
