Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, and in particular to a quick-connect sealing device for fire hydrant pressure testing connectors. Background Technology

[0002] In the daily maintenance and inspection of fire protection systems, the pressure testing of fire hydrants is of paramount importance. The pressure status of fire hydrants directly affects whether fire-fighting equipment can function properly during a fire, ensuring the safety of people's lives and property. Accurately measuring the pressure of fire hydrants helps to promptly identify problems in the fire water supply system, such as pipe blockage or insufficient water pressure, thereby ensuring that the fire protection system is always in a reliable operating condition.

[0003] Existing pressure testing connectors often use cumbersome methods such as threaded connections when connecting to fire hydrants. On the one hand, the threaded connection process is time-consuming, requiring operators to spend a lot of time aligning and tightening. On the other hand, after long-term use, threaded connections are prone to loosening due to wear and rust, leading to water leakage. Furthermore, the water pressure inside fire hydrants is high, and if the seal is not tight, pressure leakage will occur, causing the pressure test results to be inaccurate and unable to truly reflect the actual pressure inside the fire hydrant, thus affecting the accuracy of pressure measurement.

[0004] To address this, a quick-connect sealing device for fire hydrant pressure testing connectors is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A quick-connect sealing device for a fire hydrant pressure testing connector includes a fire hydrant body 1 and a pressure testing connector body 2. A connecting pipe 3 is fixedly sleeved on the surface of the fire hydrant body 1. A quick-connect mechanism 4 is fixedly sleeved on the surface of the connecting pipe 3 and the surface of the pressure testing connector body 2. The quick-connect mechanism 4 includes a fixing component 41 and a connecting component 42. The connecting component 42 includes a second connecting sleeve 421. A sealing component 5 is provided on the surface of the fixing component 41.

[0027] The fixing component 41 includes a first connecting sleeve 411, which is fixedly sleeved on the surface of the connecting tube 3. A mating groove 412 is provided on the side of the first connecting sleeve 411 near the second connecting sleeve 421. A groove 413 is provided on the inner wall of the mating groove 412. A movable rod 414 is movably connected through the inside of the groove 413. A locking block 415 is fixedly connected to the side of the movable rod 414 located inside the groove 413. A return spring 416 is sleeved on the surface of the movable rod 414. The two ends of the return spring 416 are fixedly connected to the locking block 415 and the inner wall of the groove 413, respectively.

[0028] In this embodiment: by setting the fixing component 41, after the docking block 422 is inserted into the docking groove 412, the locking block 415 will be locked into the locking groove 423 under the action of the reset spring 416, which will firmly lock the first connecting sleeve 411 and the second connecting sleeve 421, so as to achieve a tight and stable connection between the pressure measuring connector and the fire hydrant, and ensure that there will be no loosening or falling off during pressure measurement.

[0029] Specifically, such as Figure 2 , Figure 4 As shown, the second connecting sleeve 421 is fixedly connected to the surface of the pressure testing connector body 2, and a mating block 422 is fixedly connected to the side of the second connecting sleeve 421 near the first connecting sleeve 411.

[0030] Specifically, such as Figure 4 As shown, the docking block 422 is slidably connected inside the docking groove 412, and the surface of the docking block 422 is provided with a slot 423, which is used in conjunction with the slot 415.

[0031] Specifically, such as Figure 3 As shown, a pull ring 6 is fixedly connected to the side of the movable rod 414 away from the locking block 415, and a tension spring 7 is sleeved on the surface of the movable rod 414. The two ends of the tension spring 7 are fixedly connected to the pull ring 6 and the surface of the first connecting sleeve 411, respectively.

[0032] In this embodiment: Through the above settings, the docking block 422 can cooperate with the docking groove 412, providing precise guidance for the connection of the pressure testing connector body 2 and the fire hydrant body 1. When connecting, the operator only needs to align the docking block 422 with the docking groove 412 and insert it to quickly and accurately complete the initial positioning without spending a lot of time adjusting the position, which greatly improves the connection efficiency. The slot 423 on the surface of the docking block 422 can be used in conjunction with the locking block 415 in the fixing component 41. The tight cooperation between the slot 423 and the locking block 415 forms a reliable mechanical locking structure. When the water pressure inside the fire hydrant is high, this locking structure can withstand greater pressure, preventing the pressure testing connector from loosening or falling off during use and ensuring the stability of the connection. The tension spring 7 can provide a stable pulling force for the movable rod 414, preventing the locking block 415 from accidentally exiting the slot 423, thereby ensuring the reliability of the connection. When it is necessary to disassemble the pressure testing connector, the operator only needs to pull the pull ring 6 to overcome the elastic force of the return spring 416 and the pulling force of the tension spring 7, so that the locking block 415 can be removed from the slot 423, and the pressure testing connector and the fire hydrant can be easily separated, thereby improving the convenience of use.

[0033] Specifically, such as Figure 5 As shown, the sealing assembly 5 includes a mounting plate 501, which is fixedly sleeved on the surface of the first connecting sleeve 411. A mounting groove 502 is provided on the side of the mounting plate 501 near the second connecting sleeve 421, and a bidirectional screw 503 is rotatably connected inside the front mounting groove 502. The top and bottom ends of the surface of the bidirectional screw 503 are threaded with screw blocks 504.

[0034] Specifically, such as Figure 5 As shown, a connecting bracket 505 is fixedly connected to the outer side of the screw block 504, and an arc plate 506 is fixedly connected to the opposite side of the two connecting brackets 505. The arc plate 506 is used in conjunction with the first connecting sleeve 411 and the second connecting sleeve 421.

[0035] Specifically, such as Figure 2 As shown, the surfaces of the first connecting sleeve 411 and the second connecting sleeve 421 are both provided with annular grooves 8, and the inner wall of the arc plate 506 is fixedly connected with a sealing ring 9, which is used in conjunction with the annular groove 8.

[0036] In this embodiment: by setting the sealing assembly 5, the mounting plate 501 can provide a mounting base for other components, ensuring that the relative position of the sealing assembly 5 and the first connecting sleeve 411 is fixed, and ensuring that the entire sealing assembly 5 can accurately seal the first connecting sleeve 411 and the second connecting sleeve 421. By rotating the bidirectional screw 503, the two screw blocks 504 on its surface can be moved simultaneously to the middle or both ends, thereby driving the connecting frame 505 and the arc plate 506 to move. Under the drive of the connecting frame 505, the two arc plates 506 can seal the first connecting sleeve 411 and the second connecting sleeve 421. The two connecting sleeves 421 tightly wrap around the first connecting sleeve 411 and the second connecting sleeve 421 to prevent water from seeping out from the connection point. At the same time, the arc plate 506 can also provide some protection for the connecting sleeves to prevent external impurities from entering the connection point. The annular groove 8 can be used in conjunction with the sealing ring 9. When the arc plate 506 wraps around the first connecting sleeve 411 and the second connecting sleeve 421, the sealing ring 9 will be embedded in the annular groove 8. After being squeezed, it will deform and tightly fit the inner wall of the annular groove 8, filling the tiny gaps in the connection point and preventing water from leaking from the connection point, thereby achieving a sealing effect.

[0037] Specifically, such as Figure 5 As shown, a limiting block 10 is slidably connected inside the rear mounting groove 502, and the side of the limiting block 10 near the connecting frame 505 is fixedly connected to the connecting frame 505.

[0038] In this embodiment: by setting a limiting block 10, when the bidirectional screw 503 drives the screw block 504, the connecting frame 505 and the arc plate 506 to move together, the limiting block 10 will move together with the connecting frame 505. Since the limiting block 10 can only slide in the mounting groove 502, the arc plate 506 can only move along the predetermined route, which improves the stability of the arc plate 506 when it moves, and makes the sealing assembly 5 more stable and reliable when sealing the connecting sleeve.

[0039] Working principle: First, align the mating block 422 with the mating groove 412. Then, push the pressure testing connector body 2 so that the mating block 422 slides into the mating groove 412. During the insertion of the mating block 422 into the mating groove 412, the mating block 422 will squeeze the locking block 415, causing the locking block 415 to drive the movable rod 414 into the groove 413. At the same time, the return spring 416 is compressed. When the locking groove 423 on the mating block 422 is aligned with the locking block 415, the locking block 415 is locked into the locking groove 423 under the elastic force of the return spring 416, thereby realizing the connection between the first connecting sleeve 411 and the second... The connecting sleeve 421 is quickly connected and initially fixed. Then, the bidirectional screw 503 is rotated. The rotation of the bidirectional screw 503 will drive the two screw blocks 504 connected by threads on its surface to move towards or away from each other in the mounting groove 502 of the mounting plate 501. The screw blocks 504 drive the arc plate 506 to move through the connecting bracket 505. When the arc plate 506 moves to contact the first connecting sleeve 411 and the second connecting sleeve 421, the sealing ring 9 on the inner wall of the arc plate 506 will be embedded in the annular groove 8 on the surface of the first connecting sleeve 411 and the second connecting sleeve 421, thereby achieving a good sealing effect.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
