[0044] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0045] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 As shown, Figure 1 , Figure 2 , Figure 5 , Figure 7The movable part 130 is accommodated in the first locking section 210 of the slide. The utility model proposes a leak-proof fire hydrant with an elastic component, including a pumping rod 100, an adjusting member 200, an elastic component 300 and a water outlet valve 400; the pumping rod 100 includes a shaft body 110, a first sealing portion 120 and a movable part 130, the shaft body 110 extends in a vertical direction, the first sealing portion 120 is connected to the lower end of the shaft body 110, and the movable part 130 is connected to the radial direction of the shaft body 110; the adjusting member 200 has a slide, and the movable part 130 is partially located in the slide, and can simultaneously drive the pumping rod 100 to move in the vertical direction when moving in the slide, the slide includes a first locking section 210 and an adjusting section 250, and the adjusting section The lower end of 250 is connected to the first locking section 210; one end of the elastic component 300 is connected to the adjusting member 200, and the other end is connected to the movable part 130; the water outlet valve 400 has a water outlet hole 410, and the water outlet hole 410 extends in the vertical direction. When the movable part 130 is partially located in the first locking section 210, the movable part 130 abuts against the inner wall of the first locking section 210 and is subjected to the downward force of the inner wall of the first locking section 210, the elastic component 300 applies an upward force to the movable part 130, and the first sealing part 120 is located in the water outlet hole 410 and closes the water outlet hole 410; when the movable part 130 is partially located in the adjusting section 250, the first sealing part 120 can be detached from the water outlet hole 410.

[0046] Through the above scheme, the moving part 130 partially located in the chute can move in the chute, thereby driving the pumping rod 100 to move up and down. When the moving part 130 is partially located in the first locking section 210, the first sealing part 120 is located inside the water outlet 410 and closes the water outlet 410; when the water located on the side of the water outlet 410 away from the pumping rod 100 presses the first sealing part 120 upward by water pressure, the upper inner wall of the first locking section 210 can exert a downward force to limit the rise of the first sealing part 120, and the first sealing part 120 can continue to close the water outlet to prevent water leakage; when the moving part 130 is partially located in the adjustment section 250, the first sealing part 120 can be separated from the water outlet 410, so that the water located below the water outlet 410 can flow into the water outlet 410. The leak-proof fire hydrant with an elastic component can change the vertical position of the moving part 130 by adjusting the position of the moving part 130 in the slide groove, thereby adjusting the vertical position of the first sealing part 120 connected to the lower end of the shaft body 110 and adjusting the opening and closing of the water outlet 410.

[0047] When the movable portion 130 is partially located in the first locking section 210, the first sealing portion 120 is continuously impacted by the water flow from below the water outlet 410; since the movable portion 130 abuts against the inner wall of the first locking section 210 and is subjected to a downward force, the elastic component 300 applies an upward force to the movable portion 130, so that the movable portion 130 can be stably maintained in the first locking section 210, and the first sealing portion 120 will not become loose relative to the water outlet 410, thereby reducing the occurrence of water leakage.

[0048] It should be noted that in the above scheme, “the movable portion 130 abuts against the inner wall of the first locking segment 210 and is subjected to the downward force of the inner wall of the first locking segment 210” should be understood as that the movable portion 130 only has a tendency to move downward under the force exerted by the inner wall of the first locking segment 210, and will not deviate in other directions.

[0049] Specifically, according to some embodiments of the present invention, the inner wall of the first locking section 210 includes a horizontal plane arranged downward, and when the moving part 130 is located in the first locking section 210, the moving part 130 directly contacts the above plane; the above plane only provides a downward force on the moving part 130. Those skilled in the art can appropriately adjust the size of the above plane, so that when the moving part 130 is impacted in the horizontal direction and produces a short-distance displacement, the moving part 130 can maintain contact with the above plane, thereby remaining in the first locking section 210, preventing the moving part 130 from entering the adjustment section 250 and causing the first sealing part 120 to be separated from the water outlet 410.

[0050] Please refer to Figure 1 , Figure 2 , Figure 5As shown, as a preferred embodiment, the inner wall of the adjustment section 250 includes an adjustment wall 260, which is arranged downward, and the first locking section 210 includes a locking groove 220; the inner wall of the first locking section 210 includes a locking wall 230, which is arranged downward, connected to the adjustment wall 260 and defines the locking groove 220; the locking groove 220 is recessed upward relative to the lower end of the adjustment wall 260; when the movable portion 130 is partially located in the first locking section 210, the movable portion 130 can be partially accommodated in the locking groove 220. Through the above scheme, when the movable part 130 is partially located in the first locking section 210, the movable part 130 can be partially accommodated in the locking groove 220. Since the elastic component 300 applies an upward force to the movable part 130, and the locking groove 220 is recessed upward relative to the lowermost end of the adjusting wall 260, when the movable part 130 is impacted in the horizontal direction, the movable part 130 will be subjected to a force in the opposite direction of the impact by the locking wall 230 that defines the locking groove 220, so that the movable part 130 eventually returns to its original stable position and will not move to the adjusting section 250; when the movable part 130 is impacted in the horizontal direction for multiple times, since the movable part 130 can return to its original stable position after each impact, the impact in the horizontal direction will not cause the movable part 130 to produce a short-distance displacement, thereby avoiding the accumulation of short-distance displacements caused by multiple impacts, and the movable part 130 can stably stay in the original position and ensure the sealing effect of the first sealing part 120.

[0051] As for the specific shape of the locking wall 230 , those skilled in the art should set it under the premise of ensuring that the moving part 130 can be partially accommodated in the locking groove 220 .

[0052] As a preferred embodiment, please refer to Figure 2 , Figure 5 As shown, Figure 2 , Figure 5 The movable portion 130 is shown below the locking groove 220 (at Figure 2 , Figure 5The elastic component 300 in the illustrated embodiment does not provide an upward elastic force to the moving part 130). According to some embodiments of the present invention, the moving part 130 is a round rod extending radially relative to the shaft body 110, and the locking wall 230 defines a semicircular locking groove 220 corresponding to the radial cross-sectional shape of the moving part 130; when the elastic component 300 provides an upward elastic force to the moving part 130, the moving part 130 enters the locking groove 220 upward, and the upper half of the moving part 130 abuts against the locking wall 230. When the moving part 130 is accommodated in the locking groove 220 and is impacted, the locking wall 230 can provide a horizontal reverse force to offset the horizontal displacement of the moving part 130 caused by the impact. Without departing from the inventive concept of the present invention, the shape of the locking groove 220 does not need to be completely matched with the shape of the radial cross-sectional shape of the moving part 130. For example, the shape of the locking groove 220 can also be a square, a triangle, other polygons, or other irregular shapes.

[0053] In order to enable the first sealing part 120 to disengage from the water outlet hole 410 when the movable part 130 slides in the adjustment section 250, the adjustment section 250 should provide the movable part 130 with a vertical movement stroke, so that the vertical position of the movable part 130 when it is located at the highest point of the adjustment section 250 is higher than the vertical position of the movable part 130 when it is located in the first locking section 210, thereby enabling the first sealing part 120 to move upward and disengage from the water outlet hole 410.

[0054] As for the specific shape of the adjustment section 250, for example, according to some embodiments of the present invention, the adjustment section 250 extends in the vertical direction, and when the movable part 130 is partially located in the adjustment section 250, the movable part 130 can move in the vertical direction and drive the first sealing part 120 to move in the vertical direction synchronously through the shaft 110. It should be noted that when the water pressure at the water outlet 410 is too high, the adjustment section 250 extending in the vertical direction will cause the movable part 130 to rise too fast, thereby causing the movable part 130 to collide with the inner wall of the upper end of the adjustment section 250, making the movable part 130 more susceptible to damage; on the other hand, when the water pressure at the water outlet 410 is relatively low, the adjustment section 250 extending in the vertical direction will cause the staff to directly lift the upper end of the pumping rod 100 to open the water outlet 410, and it is more laborious to move the pumping rod 100.

[0055] Please refer to Figure 1 , Figure 2 , Figure 6As shown, as a preferred form of the specific shape of the adjustment section 250, in some embodiments, the adjustment section 250 is a spiral groove. When the moving part 130 is partially located in the adjustment section 250, the moving part 130 can rise along the adjustment section 250 spirally and drive the first sealing part 120 to rise. When the water pressure at the water outlet 410 is too high, the downward inner wall of the adjustment section 250 can provide a downward support force for the moving part 130 to offset a part of the impact force of the water pressure, thereby providing a buffering effect for the rising moving part 130 in the adjustment section 250. On the other hand, when the water pressure at the water outlet 410 is small, the staff can open the water outlet 410 by rotating the pumping rod 100, and the upward inner wall of the adjustment section 250 can provide an upward support force for the moving part 130, and moving the pumping rod 100 is more labor-saving; those skilled in the art can also set a handle in the radial direction of the shaft body 110 on the basis of the above scheme to increase the force arm of the rotation, so that the process of rotating and rising of the moving part 130 is more labor-saving.

[0056] For further information, please refer to Figure 1 , Figure 2 , Figure 7 As shown, in some embodiments, the elastic component 300 includes a first elastic member 310, one end of which is connected to the bottom of the adjusting member 200, and the first elastic member 310 is kept in a compressed state in the vertical direction, and always provides an upward elastic force to the moving part 130. Through the above scheme, when the moving part 130 is partially located in the adjusting section 250, the first elastic member 310 in a compressed state always provides an upward thrust to the moving part 130, so that the moving part 130 is easier to move upward along the moving part 130, so that the first sealing part 120 is easier to detach from the water outlet 410.

[0057] In other embodiments, the elastic component 300 includes a second elastic member, one end of which is connected to the top of the adjusting member 200, and the second elastic member is kept in a stretched state in the vertical direction, and always provides an upward elastic force to the moving part 130. Through the above scheme, when the moving part 130 is partially located in the adjusting section 250, the first elastic member 310 in a stretched state always provides an upward pulling force to the moving part 130, so that the moving part 130 is easier to move upward along the moving part 130, thereby making it easier for the first sealing part 120 to detach from the water outlet 410. Without departing from the inventive concept of the utility model, the elastic component 300 includes the first elastic member 310 and the second elastic member, and the first elastic member 310 and the second elastic member jointly provide an upward elastic force to the moving part 130 partially located in the adjusting section 250.

[0058] For further information, please refer to Figure 1 , Figure 2 , Figure 6As shown, in some embodiments, the chute further includes a second locking section 240, the second locking section 240 extends in the vertical direction, the upper end of the adjustment section 250 is connected to the lower end of the second locking section 240, and when the moving part 130 is partially located in the second locking section 240, the first sealing part 120 is located above the water outlet 410. Through the above scheme, when the vertical position of the moving part 130 reaches the highest point of the adjustment section 250, it can enter the second locking section 240 in the vertical direction through the elastic component 300, and the second locking section 240 can limit the horizontal movement of the moving part 130, thereby increasing the stability of the pumping rod 100.

[0059] On the other hand, when the upper end of the adjustment section 250 is oriented at an angle to the vertical direction, the second locking section 240 can provide force feedback to the staff, reminding the staff that the first sealing portion 120 has been separated from the water outlet 410. For example, please refer to Figure 2 As shown, as mentioned above, the adjustment section 250 can be a spiral groove, then the upper end of the adjustment section 250 will have an angle with the second locking section 240. When the movable portion 130 is partially located at the upper end of the adjustment section 250, the movable portion 130 will abut against the inner wall of the second locking section 240 in the horizontal direction, thereby generating a force opposite to the rotation direction on the staff who rotates the pumping rod 100, reminding the staff that the pumping rod 100 has been rotated to the corresponding position.

[0060] Without departing from the inventive concept of the utility model, those skilled in the art may set a plurality of slide grooves on the adjusting member 200, set a plurality of moving parts 130 on the circumference of the shaft body 110, and make each moving part 130 partially accommodated in a different slide groove. The above scheme can make the adjustment process of the pumping rod 100 more stable. Figure 2 , Figure 6 As shown, according to some embodiments of the present invention, the pumping rod 100 includes two moving parts 130, and the adjusting member 200 has two slide grooves. The two moving parts 130 are mirror-imaged relative to the shaft body 110, and the slide grooves are symmetrically arranged relative to the center of the shaft body 110.

[0061] For further information, please refer to Figure 1 , Figure 2 , Figure 4 As shown, in some embodiments, the leak-proof fire hydrant with an elastic component further includes a bolt body 500, which extends in a vertical direction and defines a fire extinguishing chamber 510, in which the pumping rod 100, the adjusting member 200 and the water outlet valve 400 are all arranged, and the water outlet hole 410 is connected to the fire extinguishing chamber 510. Through the above scheme, the pumping rod 100, the adjusting member 200 and the water outlet valve 400 can be protected by the bolt body 500, reducing direct interference of the outside world on the pumping rod 100, the adjusting member 200 and the water outlet valve 400.

[0062] The above has described the scheme of setting the adjustment section 250 as a spiral groove. In some embodiments, please refer to Figure 2 , Figure 6 As shown, on the basis of the bolt body 500 provided on the leak-proof fire hydrant with an elastic component, a special-shaped groove 150 is also provided on the top of the shaft body 110. Technical personnel in this field can provide a handle with a structure that cooperates with each other according to the shape of the special-shaped groove 150. Only by using a handle that matches the special-shaped groove 150 can the pumping rod 100 in the bolt body 500 be driven to rotate together with the handle through the structure on the handle that cooperates with the special-shaped groove 150. The above scheme can increase the anti-theft performance of the leak-proof fire hydrant with an elastic component and increase the safety of the leak-proof fire hydrant with an elastic component.

[0063] For further information, please refer to Figure 1 , Figure 2 , Figure 7 As shown, in some embodiments, the adjusting member 200 has an adjusting channel 270, which penetrates the adjusting member 200 in a vertical direction, and the upper end of the shaft body 110 extends out from the fire extinguishing chamber 510 through the adjusting channel 270; the pumping rod 100 also includes a second sealing portion 140, which is connected to the shaft body 110, located in the adjusting channel 270 and covering the circumferential inner wall of the adjusting member 200 to block the fire extinguishing chamber 510 from the outside. Through the above scheme, the upper end of the shaft body 110 extends out from the fire extinguishing chamber 510 so that the staff can operate the pumping rod 100 outside the bolt body 500 to adjust the opening and closing state of the water outlet 410; on the basis of the above, the second sealing portion 140 can cover the circumferential inner wall of the adjusting member 200 to close the adjusting channel 270, blocking the fire extinguishing chamber 510 and the outside world, thereby preventing the water below the water outlet 410 from leaking into the fire extinguishing chamber 510 in an accidental situation and not continuing to leak from the adjusting channel 270 to the outside world.

[0064] For further information, please refer to Figure 1 , Figure 3 , Figure 8As shown, in some embodiments, the leak-proof fire hydrant with an elastic component also includes a reinforcement 600, a buffer 700 and a third elastic member 800. The buffer 700 is accommodated in the fire extinguishing chamber 510, and the reinforcement 600 is connected to the inner wall of the fire extinguishing chamber 510; the buffer 700 divides the fire extinguishing chamber 510 into a first chamber 511 and a second chamber 512, and the first chamber 511 is located above the second chamber 512. The buffer 700 has a buffer channel 710, and the buffer channel 710 penetrates the buffer 700 in a vertical direction. The two ends of the buffer channel 710 are respectively connected to the first chamber 511 and the second chamber 512, and the second chamber 512 is connected to the water outlet 410; the third elastic member 800 and the reinforcement 600 are located in the first chamber 511, and the two ends of the third elastic member 800 in the vertical direction are respectively connected to the buffer 700 and the reinforcement 600. Through the above scheme, when it is necessary to use a leak-proof fire hydrant with an elastic component, the water below the water outlet 410 passes through the second chamber 512, the buffer channel 710 and the first chamber 511 in sequence. When the water pressure is too high, the buffer component 700 can absorb part of the impact force of the water flow through the third elastic component 800 and convert it into elastic potential energy, thereby reducing the water pressure, avoiding the inside of the plug body 500 from being in a high-pressure state, and extending the service life of the leak-proof fire hydrant with an elastic component.

[0065] Please refer to Figure 8 As shown, as a preferred solution, the leak-proof fire hydrant with an elastic component further includes a guide structure 900, which extends in the vertical direction and is connected to the reinforcement member 600, and the buffer member 700 is slidably connected to the guide structure 900. The above solution can limit the relative rotation between the buffer member 700 and the bolt body 500, so that the buffer member 700 moves more smoothly.

[0066] For further information, please refer to Figure 1 , Figure 3 , Figure 8 As shown, in some embodiments, the buffer channel 710 has a buffer section 711 and a channel section 712 that are interconnected from bottom to top, the buffer section 711 is connected to the second chamber 512, and the horizontal cross-sectional area of ​​the inner wall of the buffer section 711 gradually decreases from bottom to top; the channel section 712 is connected to the first chamber 511. Through the above scheme, before the water in the second chamber 512 flows into the first chamber 511 through the buffer channel 710, it will be guided by the inner wall of the buffer section 711 and enter the channel section 712, and its own water pressure will be further reduced.

[0067] For further information, please refer to Figure 1 , Figure 4As shown, in some embodiments, the leak-proof fire hydrant with an elastic component also includes a drain member 1000, which is arranged in the fire extinguishing chamber 510, and the shaft body 110 is drivingly connected to the drain member 1000; the bolt body 500 also has a drain hole 520, which is connected to the outside world; when the movable part 130 is partially located in the first locking section 210, the drain member 1000 avoids the drain hole 520, and the fire extinguishing chamber 510 is connected to the outside world through the drain hole 520; when the movable part 130 is partially located in the adjusting section 250, the drain member 1000 can close the drain hole 520. Through the above scheme, when the movable part 130 is partially located in the first locking section 210, the water in the fire extinguishing chamber 510 can escape through the drainage hole 520, so as to prevent the accumulated water in the fire extinguishing chamber 510 from continuously eroding the internal structure of the leak-proof fire hydrant with an elastic component, thereby extending the service life of the leak-proof fire hydrant with an elastic component; when the movable part 130 is partially located in the adjustment section 250, the drainage part 1000 closes the drainage hole 520, so that the water entering the fire extinguishing chamber 510 can be discharged from the preset outlet of the leak-proof fire hydrant with an elastic component, which will not affect the normal use of the leak-proof fire hydrant with an elastic component.

[0068] For details on the transmission connection between the drain member 1000 and the shaft body 110, please refer to Figure 4 As shown, according to some embodiments of the present invention, a worm structure is provided on one side of the shaft body 110 near the water outlet 410, a transmission gear set is provided inside the bolt body 500, and teeth arranged in the vertical direction are provided on the drain member 1000. When the moving part 130 drives the shaft body 110 to rise, the worm structure rises together and drives the transmission gear set to rotate. The rotating transmission gear set drives the teeth on the drain member 1000 to move downward one by one, and the drain member 1000 closes the drain hole 520. When the moving part 130 drives the shaft body 110 to descend, the worm structure descends together and connects the drain hole 520 with the fire extinguishing chamber 510, so that the liquid in the fire extinguishing chamber 510 can flow out from the drain hole 520. Without departing from the inventive concept of the present invention, those skilled in the art may also set other transmission structures between the drain member 1000 and the shaft body 110, such as a connecting rod structure, a pulley structure, etc., to achieve a transmission connection between the drain member 1000 and the shaft body 110.

[0069] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
