Description
Technical Field
[0001] This utility model relates to the technical field of fire hydrant equipment components, and in particular to a quick-installation fire hydrant box connecting buckle. Background Technology
[0002] Fire hydrant boxes are enclosures used to store and protect fire hydrants, hoses, and nozzles. Their main function is to provide firefighters or on-site personnel with a quick and convenient access to fire equipment during a fire, ensuring rapid firefighting operations in emergencies. They also protect the equipment inside from external environmental factors, keeping it in good working order. The fire hydrant system is a key component of urban fire protection infrastructure, providing a reliable water source for firefighting. It quickly and effectively connects fire hoses and water sources, ensuring firefighters can promptly carry out firefighting operations. It plays a crucial role in controlling the spread of fire and protecting life and property.
[0003] In the past, welding was commonly used to connect fire hydrant boxes. Welded connections are permanent and difficult to alter once completed, hindering maintenance, repair, and component replacement. Furthermore, welding can cause deformation, affecting the box's sealing and overall structural strength. The existing bolted connection method involves tightening bolts individually for installation, and loosening them for use and maintenance. This method provides a very secure connection, is resistant to external damage, and allows for replacement of deformed boxes. However, the installation and disassembly process is cumbersome, slow, and time-consuming. In large buildings or public places where multiple fire hydrant boxes need to be installed, bolted connections make installation extremely difficult, extending the overall construction period. Specialized tools are required, and in emergencies, rapid connection and disassembly may be impossible, impacting fire rescue efficiency and failing to meet user needs. Utility Model Content

A spring 10 is fixedly connected to the left side of the support column 9. The spring 10 has a spiral structure with twenty tightly arranged coils. Its function is to respond quickly when the pawl 6 in the mechanical device is lifted, to exert its inherent elastic potential energy, and to provide a strong contraction force. This contraction force is precise and efficient, ensuring that the pawl 6 can quickly and smoothly return to its initial position after being lifted, thereby maintaining the stable operation of the entire mechanical system. For smooth and efficient operation, this function of spring 10 is crucial for ensuring normal operation and extending service life. A fixing block 11 is fixedly connected to the rear side of spring 10. The function of fixing block 11 is to ensure that spring 10 maintains a stable position during movement. In addition, a housing 2 12 is provided at the bottom of housing 1. A limiting groove 13 is provided at the top of housing 2 12. The limiting groove 13 is used to limit the range of movement of certain components, thereby ensuring the normal operation of the mechanism. A mounting mechanism 2 is fixedly connected to the bottom of housing 2 12. The main function of mounting mechanism 2 is to quickly and firmly install the housing, ensuring that the entire device has good stability and reliability during use.
[0033] Please see the appendix Figure 3 - Appendix Figure 5The installation mechanism 2 includes a base plate 201.

U-shaped iron rings 207 are fixedly connected to the left and right sides of the top of the box connecting plate 202. A special-shaped hole 208 is opened in the middle of the bottom of the U-shaped iron ring 207.
[0034] Specifically, the installation mechanism 2 includes a base plate 201. The top of the base plate 201 is fixedly connected to the bottom of the housing 12 to ensure its stability. At the bottom of the base plate 201, a housing connecting plate 202 is provided for connecting the housing to facilitate the installation and fixation of the entire mechanism. U-shaped iron rings 203 are firmly fixedly connected to the left and right sides of the top of the base plate 201 to enhance the stability of the structure. A threaded post 205 is installed in the middle of the U-shaped iron ring 203 through a threaded connection. The top of the threaded post 205 is fixedly connected to... A user-friendly knob 204 allows the user to adjust the position of the threaded post 205 by rotating the knob 204. A torsion block 206 is fixedly connected to the bottom of the threaded post 205. The torsion block 206 provides stable support during adjustment. In addition, U-shaped iron rings 207 are fixedly connected to the top left and right sides of the box connecting plate 202. A specially shaped hole 208 is opened in the middle of the bottom of the U-shaped iron ring 207. The special-shaped hole 208 is for precise matching with other components to ensure the stability and functionality of the entire mounting mechanism 2.
[0035] Please see the appendix Figure 3 - Appendix Figure 5 Positioning blocks 14 are fixedly connected to the top left and right sides of the box connecting plate 202 near the front edge. Square holes 15 are opened on the top left and right sides of the bottom plate 201 near the front edge. Multiple screws 16 are threaded to the top of the U-shaped iron ring 207. Multiple screws 27 are threaded to the top of the U-shaped iron ring 203. A square groove 18 is opened on the top right side of the shell 2. A rotating knob 19 is fixedly connected to the bottom of the rotating column 4.
[0036] Specifically, on the left and right sides of the top of the housing connecting plate 202, particularly near the front edge, dedicated positioning blocks 14 are securely fixed. These positioning blocks 14 ensure precise alignment of the housing connecting plate 202 with other components. Similarly, on the left and right sides of the top of the bottom plate 201, also near the front edge, regularly shaped square holes 15 are provided. These square holes 15 are used for connection with other components. Furthermore, the top surface of the U-shaped iron ring 207 is securely connected with multiple screws 16 via threaded connections. 6 is used for fastening and adjusting the position of related components. Similarly, the U-shaped iron ring 203 is also equipped with multiple screws 17 on its top plane by means of threaded connection. These screws 17 also serve the purpose of fastening and adjustment. Furthermore, the housing 12 has a regularly shaped square groove 18 on its top right side. The square groove 18 is used to accommodate and cooperate with the insertion of other components. Finally, the rotating column 4 is connected to an easy-to-operate rotary knob 19 at its bottom position by a sturdy fixing method. The rotary knob 19 is used to control the rotation of the rotating column 4, thereby realizing the effective operation of related functions.
[0037] Please see the appendix Figure 1 - Appendix Figure 3 A knob 20 is fixedly connected to the top of the rotating column 4. Anti-slip sleeves 23 are fixedly connected to the front and rear sides of the knob 20. A warning sign 21 is provided on the front side of the housing 1. Screws 3 22 are threadedly connected to the corners of the front side of the warning sign 21. A limit ring 24 is fixedly connected to the outer wall of the rotating shaft 7 near the top edge. Multiple limit blocks 25 are fixedly connected to the top of the housing 1.
[0038] Specifically, a knob 20 is securely fixed to the top of the rotating column 4. This knob 20 is easy for the user to operate. To enhance the grip and anti-slip performance of the knob 20, anti-slip sleeves 23 are securely attached to both its front and rear sides. These anti-slip sleeves 23 are made of a special material to effectively prevent hand slippage during operation. Furthermore, a prominent indicator 21 is located on the front of the housing 1. This indicator 21 conveys important information or operational tips to the user. To ensure the stability of the indicator 21, screws 22 are threadedly fixed to the corners on its front side. These screws 22 play a crucial role in... Furthermore, the rotating shaft 7 has a limiting ring 24 fixedly connected to its outer wall near the top edge. The main function of the limiting ring 24 is to effectively limit the range of motion of the pawl 6, thereby avoiding the failure of locking due to up-and-down shaking. This not only improves the overall stability of the structure, but also significantly enhances the reliability and durability of the system, making the entire mechanism run more smoothly and reducing the possibility of failure. Finally, the housing 1 has multiple limiting blocks 25 evenly fixedly connected to its top. These limiting blocks 25 further ensure the stability and accuracy of the rotating column 4 and the knob 20 during operation, preventing misoperation.
[0039] Working principle: After aligning housing 1 and housing 2 12, the knob 19 is inserted into the limiting groove 13 inside housing 2 12. The knob 20 is rotated, causing the bottom rotating column 4 to drive the ratchet 5 to rotate, causing one end of the pawl 6 to tilt backward, and the other end to rotate. The shaft 7 connected to it rotates, ensuring that the position does not disengage. The fixing block 11 is in front of the pawl 6, and the position of the support column 9 remains unchanged. The fixing block 11 moves backward, causing the spring 10 to stretch. The special shape of the ratchet 5 means that it will only push backward a short distance before the spring 10 retracts. This structure allows the ratchet 5 to rotate counterclockwise and not backward, making it more securely engaged. It can complete the connection and disassembly in a short time, improving the response speed of fire fighting operations.
[0040] By inserting the positioning block 14 into the square hole 15, the base plate 201 and the box connecting plate 202 are aligned and fitted together. The twisting block 206 is inserted into the irregular hole 208 in the middle of the U-shaped iron ring 207. The knobs 204 on the left and right sides are rotated to the appropriate angles. The threaded post 205 fixed at the bottom drives the twisting block 206 to rotate, so that the twisting block 206 changes its original angle, so that the base plate 201 and the box connecting plate 202 will no longer separate and are tightly and firmly fitted together. This structure allows for quick installation of the buckle without the need for tools such as screwdrivers, which is more convenient, less labor-intensive, and improves efficiency.
[0041] 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.
