Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a dense fire water pipe installation structure. Background Technology

[0002] The field of fire protection equipment mainly involves equipment related to fire prevention, alarm, fire extinguishing, and personnel evacuation. In terms of fire alarm, there are fire detectors and manual fire alarm buttons, which are used to detect fires in a timely manner and issue alarm signals. There are various types of fire extinguishing equipment. Fire extinguishers can be used to extinguish initial fires. Fire hydrant systems provide water sources for fire extinguishing. Automatic sprinkler systems can automatically spray water to extinguish fires. Fire water pipes are a key component of fire protection equipment and play a vital role in fire extinguishing. In buildings, fire water pipes are generally arranged along public areas such as stairwells and corridors to form a ring or branch water supply network.

[0003] A search revealed Chinese Patent Publication No. CN214618385U, which discloses a fire-fighting water pipe installation structure, including a first connecting part and a second connecting part. The first connecting part has an insertion groove and a snap-fit ​​mounting hole on its outer circumferential surface, which communicates with the insertion groove. A snap-fit ​​is movably installed in the snap-fit ​​mounting hole, and a pressing part is provided at one end of the snap-fit ​​near the insertion groove. An elastic element is also provided in the snap-fit ​​mounting hole. The end face of the second connecting part that connects to the first connecting part has an insertion part that matches the shape of the insertion groove. The insertion end of the insertion part has a pressing engagement part that cooperates with the pressing part. During insertion, the pressing engagement part can squeeze the pressing part out of the insertion groove. A snap-fit ​​groove that matches the shape of the pressing part is also provided between the two ends of the insertion part, so that the pressing part can be snapped into the snap-fit ​​groove under the action of the elastic element during insertion. The fire water pipe installation structure proposed in this application is very convenient and quick to connect, saving time and effort; however, in actual use, the structure is installed by using snap-fit ​​parts and snap-fit ​​grooves. Although this achieves the effect of convenient installation, the sealing performance cannot be guaranteed, thereby reducing the sealing effect of the fire water pipe connection position. During long-term use, water leakage is likely to occur. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dense fire water pipe installation structure, which aims to improve the problem that the sealing performance of the existing technology cannot be guaranteed, thereby reducing the sealing effect of the fire water pipe connection position and making it prone to water leakage during long-term use.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a dense fire-fighting water pipe installation structure, including a water pipe fitting. The front and rear ends of the water pipe fitting are fixedly connected to a fixing frame. The upper and lower sides of the front fixing frame are fixedly connected to a fixing shell. A threaded rod is rotatably connected to the left side of the inner wall of the fixing shell. A sliding plate is threadedly connected to the outer wall of the threaded rod. Locking grooves are provided at the upper and lower ends of one side of the sliding plate. A knob is fixedly connected to the right end of the threaded rod. Connecting shells are fixedly connected to the upper and lower ends of the upper and lower ends of the front inner wall of the connecting shell. A locking rod is fixedly connected to the rear side of the locking rod and engages with the locking groove. A sealing sleeve is fixedly connected to the front inner wall of the front fixing frame. An extraction tube communicates with the interior of the sealing sleeve. Connecting components are provided on the left and right sides of the front fixing frame. A detection mechanism is provided on the top wall of the water pipe fitting.

[0006] The above technical solution allows for the initial locking and sealing of one end of the water pipe fitting with the sealing sleeve, followed by locking and connecting the other end of the water pipe fitting with the sealing sleeve. Then, the air inside the sealing sleeve is extracted through the extraction pipe, improving the sealing performance between the two water pipes. At the same time, the rotation of the threaded rod causes the sliding plate and locking rod to engage and lock, thus sealing and fixing the two fixed frames and preventing water leakage after prolonged use.

[0007] As a further description of the above technical solution:

[0008] The detection mechanism includes a rotating shaft, the left and right ends of which are rotatably connected to the top wall of the water pipe fitting. A connecting plate is fixedly connected to the outer wall of the rotating shaft, and a detection plate is fixedly connected to the bottom wall of the connecting plate. Multiple square grooves are equidistantly opened on one side of the detection plate. A connecting plate is fixedly connected to the top wall of the connecting plate, and an indicator plate is fixedly connected to the top of the connecting plate.

[0009] The above technical solution ensures that when water flows through, the detection plate inside the water pipe is impacted by the water flow, which in turn causes the connecting plate to deflect. This causes the indicator plate to deflect around the axis of rotation. When a leak occurs, the deflection angle of the indicator plate decreases, thus achieving the purpose of detecting whether the water pipe is leaking and improving the detection effect.

[0010] As a further description of the above technical solution:

[0011] The connecting assembly includes two locking plates. The adjacent sides of the two locking plates are rotatably connected to the left and right sides of the front fixing frame, respectively. The left and right sides of the rear fixing frame are provided with connecting slots, and the front sides of the two locking plates are respectively engaged with the corresponding connecting slots.

[0012] The above technical solution enables the front end of the locking plate to be fixed with the corresponding connecting groove when the locking plate is flipped, thereby improving the connection effect on both sides of the fixing frame.

[0013] As a further description of the above technical solution:

[0014] Both locking plates have rubber sleeves fixedly connected to their outer front sides, and the external dimensions of the two rubber sleeves are respectively matched with the internal dimensions of the corresponding connecting grooves.

[0015] The above technical solution improves the locking effect of the locking plate by connecting the rubber sleeve.

[0016] As a further description of the above technical solution:

[0017] A fixing ring is fixedly connected to the outer wall of the extraction tube, and the outer wall of the fixing ring is fixedly connected to the top left end of the front side of the fixing frame.

[0018] The above technical solution reduces wear at the connection point of the outer wall of the extraction tube by using a fixed ring.

[0019] As a further description of the above technical solution:

[0020] The front left and right ends of the front fixed frame are fixedly connected with reinforcing plates, and the rear left and right ends of the rear fixed frame are provided with engaging grooves. The front sides of the two reinforcing plates engage with the corresponding engaging grooves respectively.

[0021] The above technical solution improves the connection strength of the fixed frame during installation by connecting the reinforcing plate and the locking groove.

[0022] As a further description of the above technical solution:

[0023] The outer walls of both knobs are fixedly connected with multiple protrusions, and one side of each of the multiple protrusions is arranged in an equidistant ring.

[0024] The above technical solution increases the anti-slip effect of the knob by connecting the convex strip.

[0025] As a further description of the above technical solution:

[0026] The front fixed frame has positioning grooves at both the upper and lower ends of its front side, and the rear fixed frame has positioning posts fixedly connected to both the upper and lower ends of its rear side. The rear ends of the two positioning posts are respectively engaged with the corresponding positioning grooves.

[0027] The above technical solution improves the positioning effect during installation by making the positioning post and positioning groove interlock.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the initial locking and sealing is completed by engaging one end of the water pipe fitting with the sealing sleeve, and then the other water pipe fitting is engaged and sleeved with the other end of the sealing sleeve. The air inside the sealing sleeve is extracted by the extraction pipe, thereby improving the sealing effect between the water pipe fittings. At the same time, the sliding plate and the locking rod are engaged and locked by the rotation of the threaded rod. The two fixed frames are sealed and fixed by the rotation of the locking plate, thereby avoiding water leakage after long-term use.

[0030] 2. In this utility model, the flow of water through the water pipe causes the detection plate to be impacted by the water flow, which in turn causes the detection plate to rotate the connecting plate. The connecting plate then synchronously drives the connecting plate and the indicator plate to deflect around the axis of rotation, thereby indicating the water flow status. When a leak occurs, the deflection effect of the indicator plate is reduced, thus achieving the purpose of detecting whether the water pipe is leaking. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a dense fire-fighting water pipe installation structure, including a water pipe fitting 1. The front and rear ends of the water pipe fitting 1 are fixedly connected to a fixing frame 3. The upper and lower sides of the front fixing frame 3 are fixedly connected to a fixing shell 4. A threaded rod 5 is rotatably connected to the left side of the inner wall of the fixing shell 4. The threaded rod 5 is rotatably installed via the fixing shell 4. A sliding plate 6 is threadedly connected to the outer wall of the threaded rod 5. Locking grooves 7 are provided at the upper and lower ends of one side of the sliding plate 6. A knob 8 is fixedly connected to the right end of the threaded rod 5. A connecting shell 10 is fixedly connected to the upper and lower sides of the rear fixing frame 3. A locking rod 11 is fixedly connected to the upper and lower ends of the front side of the inner wall of the connecting shell 10. When the knob 8 is rotated, the threaded rod 5 is driven to rotate, thereby causing the sliding plate 6 to slide and displace, so that the locking groove 7 inside it engages with the locking rod 11. The rear side of the locking rod 11 engages with the locking groove 7. A sealing rod is fixedly connected to the front side of the inner wall of the front fixing frame 3. The sealing sleeve 13, under the action of locking the water pipe fitting 1, improves the sealing performance between the water pipes. The inside of the sealing sleeve 13 is connected to the extraction pipe 14, and under the action of the extraction pipe 14, the air between the sealing sleeves 13 is extracted, improving the sealing performance at the water pipe connection. The left and right sides of the front fixing frame 3 are provided with connecting components, and the top wall of the water pipe fitting 1 is provided with a detection mechanism 2. The connecting components include two locking plates 16, and the adjacent sides of the two locking plates 16 are respectively rotatably connected to the left and right sides of the front fixing frame 3. The left and right sides of the rear fixing frame 3 are provided with connecting grooves 17, and the front sides of the two locking plates 16 are respectively engaged with the corresponding connecting grooves 17.

[0040] Specifically, by engaging one end of the water pipe fitting 1 with the sealing sleeve 13, a preliminary sealing effect is achieved. Subsequently, the rear end of the other water pipe fitting 1 is connected to the other end of the sealing sleeve 13 to further enhance the integrity of the seal. By using the extraction tube 14 to extract the air inside the sealing sleeve 13, the sealing effect at the connection of the water pipe fitting 1 is improved, ensuring the tightness of the connection. When the knob 8 is rotated, the threaded rod 5 rotates synchronously, thereby driving the sliding plate 6 to move. The locking groove 7 inside the sliding plate 6 and the locking rod 11 inside the connecting shell 10 engage and lock during the displacement, thereby ensuring the stability of the connection. Under the rotation of the locking plate 16, it engages with the corresponding connecting groove 17, so that the two fixing frames 3 can be sealed and fixed together, effectively avoiding the water leakage problem that may occur after long-term use of the water pipe fitting 1, ensuring the safety and reliability of the connection of the water pipe fitting 1. By rotating the two locking plates 16, one end of them engages with the corresponding connecting groove 17, thereby improving the connection effect between the fixing frames 3.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The detection mechanism 2 includes a rotating shaft 201, with both the left and right ends of the rotating shaft 201 rotatably connected to the top wall of the water pipe fitting 1. Under the connection of the rotating shaft 201, the rotation of the detection plate 203 and the connecting plate 202 is supported. The connecting plate 202 is fixedly connected to the outer wall of the rotating shaft 201, and the detection plate 203 is fixedly connected to the bottom wall of the connecting plate 202. When the detection plate 203 is impacted by the water flow, the indicator plate 206 is deflected by the connecting plate 202. Multiple square grooves 204 are equidistantly opened on one side of the detection plate 203. The connecting plate 205 is fixedly connected to the top wall of the connecting plate 202, and the indicator plate 206 is fixedly connected to the top of the connecting plate 205, so that the indicator plate 206 can detect the water flow.

[0042] Specifically, when water flows normally through the water pipe fitting 1, the detection plate 203 is subjected to the impact force of the water flow, which causes the detection plate 203 to drive the connected disc 202 to rotate around the rotating shaft 201. As the connected disc 202 rotates, it will simultaneously drive the connected plate 205 and the indicator plate 206 to rotate together, so that the indicator plate 206 can intuitively reflect the water flow. When the water pipe fitting 1 leaks, due to the weakening of the water flow impact force, the deflection amplitude of the indicator plate 206 will decrease accordingly. By observing the deflection of the indicator plate 206, it is possible to effectively detect whether the water pipe has leaked, thereby improving the accuracy and efficiency of the detection.

[0043] Reference Figure 1 , Figure 2 and Figure 4Rubber sleeves 18 are fixedly connected to the front side of the outer wall of the two locking plates 16, and the external dimensions of the two rubber sleeves 18 are respectively matched with the internal dimensions of the corresponding connecting grooves 17; a fixing ring 15 is fixedly connected to the outer wall of the extraction tube 14, and the outer wall of the fixing ring 15 is fixedly connected to the top left end of the front side of the front fixing frame 3; a reinforcing plate 19 is fixedly connected to the left and right ends of the front side of the front fixing frame 3, and a locking groove 20 is opened on the left and right ends of the rear side of the rear fixing frame 3, and the front sides of the two reinforcing plates 19 are respectively locked into the corresponding locking grooves 20;

[0044] Specifically, the rubber sleeve 18 improves the locking effect on one side of the locking plate 16, the fixing ring 15 protects the top of the outer wall of the extraction tube 14, and the connection between the reinforcing plate 19 and the locking groove 20 improves the connection strength of the fixing frame 3.

[0045] Reference Figure 2 and Figure 4 Multiple protrusions 9 are fixedly connected to the outer walls of the two knobs 8, and one side of the multiple protrusions 9 is arranged in an equidistant ring; the upper and lower ends of the front fixed frame 3 are provided with positioning grooves 12, and the upper and lower ends of the rear fixed frame 3 are fixedly connected with positioning posts 21, and the rear ends of the two positioning posts 21 are respectively engaged with the corresponding positioning grooves 12.

[0046] Specifically, the anti-slip effect of the knob 8 is improved by fixing multiple protrusions 9, and the positioning effect of the fixed frame 3 is improved by engaging the positioning post 21 with the positioning groove 12.

[0047] Working principle: Upon initial connection, a preliminary seal is achieved by engaging one end of the water pipe fitting 1 with the sealing sleeve 13. Then, the rear end of the other water pipe fitting 1 is connected to the other end of the sealing sleeve 13. The extraction tube 14 then removes air from the sealing sleeve 13, improving the sealing effect at the connection point of the water pipe fittings 1. Simultaneously, the rotation of the knob 8 causes the threaded rod 5 to rotate, driving the sliding plate 6 to move. This causes the locking groove 7 inside the sliding plate 6 to engage with the locking rod 11 inside the connecting shell 10. Furthermore, the rotation of the locking plate 16 engages with the corresponding connecting... The engagement of groove 17 seals and fixes the two fixed frames 3, thus preventing water leakage after prolonged use of the water pipe fitting 1. When water flows through the water pipe fitting 1, the detection plate 203 is impacted by the water flow, causing the detection plate 203 to drive the connecting plate 202 to deflect around the rotating shaft 201. This causes the connecting plate 202 to simultaneously drive the connecting plate 205 and the indicator plate 206 to deflect, indicating the water flow status. When a leak occurs, the deflection amplitude of the indicator plate 206 is reduced, thus achieving the purpose of detecting whether the water pipe is leaking and improving the detection effect.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
