Description
Technical Field
[0001] This utility model relates to the field of fire hydrant technology, specifically to a quick-connect fire hydrant. Background Technology
[0002] Fire hydrants, formally known as fire shut-off hydrants, are fixed fire-fighting facilities whose main function is to control combustibles, isolate oxidizers, and eliminate ignition sources. They are divided into indoor and outdoor fire hydrants. Currently, fire hydrants are an important tool for fire brigades to fight fires. Their inadequacy and damage pose a serious threat to the safety of people's lives and property. However, in the current technology, fire hydrants do not have anti-theft functions during use, making it easy for the water source inside the fire hydrant to be stolen, resulting in water waste and affecting the practicality of the fire hydrant.
[0003] To address the aforementioned technical problems, Chinese Patent No. CN221589779U discloses a quick-connect fire hydrant, comprising a fire hydrant body, connecting mechanisms on both sides of the fire hydrant body, auxiliary components on the outside of the fire hydrant body, and two connecting pipes fixedly connected to the fire hydrant body. Each connecting pipe has an external thread, and a pipe cap is fitted onto the outside of each connecting pipe. A fixing block, which engages with the connecting pipe, is fixedly connected to the opposite side of each of the two pipe caps. A rotating rod is rotatably connected inside the pipe caps and fixing blocks, and a bearing, fixedly connected to the fixing blocks, is fixedly connected to the outside of the rotating rod.
[0004] While the aforementioned existing technical solutions protect the connection between the fire water pipe and the connecting pipe and reduce the theft of water from inside the fire hydrant, they require twisting the unlocking rod one turn at a time when assembling or separating the pipe cover and the connecting pipe. During twisting, it is necessary to continuously resist the elastic force of the return spring, and it is important to ensure that the hand does not loosen the unlocking rod during this process. If the hand slips and loosens while winding, the return spring will drive the traction belt to reset. The operation is time-consuming and laborious, affecting the efficiency of picking up and putting down the pipe cover during use. Utility Model Content

Detailed Implementation
[0021] 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.
[0022] Example: Please refer to Figures 1-4 This utility model provides a technical solution:
[0023] A quick-connect fire hydrant includes a fire hydrant body 1, with connecting pipes 2 installed at both ends of the fire hydrant body 1. A fixing seat 4 is installed on one side of the outer wall of the connecting pipe 2. A rubber pad 3 is embedded in the fixing seat 4 and the end of the connecting pipe 2 away from the fire hydrant body 1. A threaded sleeve 18 is installed at the center of the port of the connecting pipe 2. A sealing cover 19 is installed on the connecting pipe 2 and the fixing seat 4 through a plug-in mechanism. The plug-in mechanism includes a connection positioning component and a dragging component. The connection positioning component is used to install the sealing cover 19 at the port of the connecting pipe 2, and the dragging component is used to release the fixing of the sealing cover 19. In use, the device can install the sealing cover 19 at the port of the connecting pipe 2 through the connection positioning component and release the fixing of the sealing cover 19 through the dragging component. The structure is simple and easy to operate. The operator does not need to apply force to rotate the operating parts one circle at a time to complete the picking and placing process, which further reduces the workload of the operator and improves the picking and placing efficiency, so that it can be used in a timely manner.
[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the connecting positioning component includes an extension hole opened at one end of the rubber pad 3. A connecting block 5 is installed on the outer wall of the sealing cover 19 at the corresponding extension hole. A connecting groove is opened inside the fixing seat 4 at the corresponding extension hole. The connecting block 5 and the connecting groove are slidably connected. First, the sealing cover 19 is placed on the outside of the threaded sleeve 18 and fits against the rubber pad 3, so that the connecting block 5 is inserted into the inner side of the connecting groove, and the inclined surface on the connecting block 5 and the extrusion block 7 are fitted together.
[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a pressing groove is formed inside the fixed base 4 on one side of the connecting groove. A limiting seat 6 is installed on one side of the inner wall of the pressing groove. Limiting grooves are formed at both ends of the top of the limiting seat 6. A limiting block 9 is slidably connected inside the limiting groove. A pressing block 7 is installed at one end of the limiting block 9. The inner side of the connecting groove and the inner side of the pressing groove are connected. A fixing groove is formed at the bottom of the opposite side of the pressing block 7. A first spring 8 is installed between the two sets of fixing grooves. The opposite sides of the two sets of pressing blocks 7 and the connecting block 5 are formed with mutually fitting inclined surfaces. A second spring 10 is installed between one side of the limiting block 9 and the inner wall of the limiting groove. Then, the sealing cover 1 is pressed further. 9 causes the squeezing block 7 to be pressed and moved, cooperating with the limiting block 9 to move along the inner side of the limiting groove. At the same time, the first spring 8 is also stretched, while the second spring 10 is compressed. Continuous pressing causes the inclined surface of the squeezing block 7 to contact and press the slope of the abutment block 11, forcing it to retract to the inner side of the abutment groove. After the abutment groove is aligned with the positioning groove, the torsion spring 12 rebounds and drives the abutment block 11 to unfold inside the positioning groove. At this time, the rubber pad 3 is in a compressed state. Then, the sealing cover 19 is released, and the rubber pad 3 rebounds a distance, causing the abutment block 11 to abut against the inner wall of the positioning groove, completing the rapid docking of the sealing cover 19.
[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, both sides of the outer wall of the connecting block 5 are provided with abutment grooves at their inclined surfaces. An abutment rod is rotatably connected to the inner side of the abutment groove. An abutment block 11 is installed on the outer side of the abutment rod. A slope corresponding to the inclined surface is provided on one side of the abutment block 11. A torsion spring 12 is installed at one end of the abutment rod. A groove is provided on the outer wall of the extrusion block 7 at its inclined surface. A sliding hole is provided at the other end of the rubber pad 3. A sliding rod 15 is installed at the port of the connecting pipe 2 corresponding to the sliding hole. The sliding rod 15 and the sliding hole are slidably connected. Furthermore, when the fire hydrant body 1 and the connecting pipe 2 need to be used, the pull ring 14 can be fastened and pulled to both sides, so that the pull rod 13 slides inside the drag groove, while driving the extrusion blocks 7 away from each other, actively stretching the first spring 8 and compressing the second spring 10, so that the abutment block 11 moves away from the inner wall of the positioning groove.
[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the dragging assembly includes a latching rod 13 installed on one side of the extrusion block 7. An extension groove is provided on one side of the outer wall of the fixing base 4. Both sides of the inner wall of the extension groove are provided with dragging grooves extending to the inner side of the extrusion groove. A pull ring 14 is rotatably connected to one end of the latching rod 13 extending to the inner side of the extension groove. The latching rod 13 and the dragging groove are slidably connected. An iron block 17 is installed on one side of the inner wall of the extension groove located in the dragging groove. A magnetic block 16 that attracts the iron block 17 is embedded in one end of the pull ring 14. Furthermore, at this time, the compressed rubber pad 3 fully rebounds, lifting the connecting block 5 a certain distance. At this time, the pull ring 14 is released, and the abutment block 11 and the positioning groove are misaligned. It will not be locked again. At this time, the sealing cover 19 is also popped open and slides a small distance on the sliding rod 15 to avoid falling directly to the ground and causing damage. At this time, the sealing cover 19 can be removed.
[0028] The implementation principle of a quick-connect fire hydrant according to an embodiment of this application is as follows: The sealing cap 19 is placed over the outside of the threaded sleeve 18 and abuts against the rubber pad 3, causing the connecting block 5 to engage with the inner side of the connecting groove. The inclined surfaces of the connecting block 5 and the pressing block 7 are then pressed together. Continued pressing of the sealing cap 19 causes the pressing block 7 to move under pressure, coordinating with the movement of the limiting block 9 along the inner side of the limiting groove. Simultaneously, the first spring 8 is stretched, while the second spring 10 is compressed. Continued pressing causes the inclined surface of the pressing block 7 to contact and press against the slope of the abutment block 11, forcing it to retract into the abutment groove. Once the abutment groove aligns with the positioning groove, the torsion spring 12 rebounds, causing the abutment block 11 to unfold inside the positioning groove. At this time, the rubber pad 3 is compressed. Then, the sealing cap 19 is released, and the rubber pad 3... After rebounding a certain distance, the abutment block 11 abuts against the inner wall of the positioning groove, completing the quick docking of the sealing cover 19. When the fire hydrant body 1 and connecting pipe 2 need to be used, the pull ring 14 can be pulled to both sides, causing the pull rod 13 to slide inside the drag groove. At the same time, the squeezing blocks 7 are driven away from each other, actively stretching the first spring 8 and compressing the second spring 10, so that the abutment block 11 is away from the inner wall of the positioning groove. At this time, the compressed rubber pad 3 fully rebounds, lifting the connecting block 5 a certain distance. At this time, the pull ring 14 is released and the abutment block 11 is misaligned with the positioning groove, and it will not be locked again. The sealing cover 19 is also bounced open and slides a small distance on the sliding rod 15 to avoid falling directly to the ground and causing damage. At this time, the sealing cover 19 can be removed.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
