Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to a fire hydrant box used for indoor building fire protection. Background Art

[0002] A fire extinguisher box is a fire-fighting equipment for placing fire-fighting tools. When a fire occurs, the fire extinguisher box is opened to take out the fire-fighting tools for extinguishing the fire. For example, a fire extinguisher box is used to place fire extinguishers. A fire extinguisher is a portable fire-fighting tool. Fire extinguishers contain chemicals for extinguishing fires. Fire extinguishers are one of the common fire-fighting facilities and are currently the most widely used fire-fighting tool. They are generally stored in public places or places where fires may occur.

[0003] The general steps of using a fire hydrant box are to open the fire hydrant box, connect the hose to the fire hose joint, and then open the valve of the fire hose joint to spray water for fire extinguishing. However, due to the limited number of uses of the fire hose, the water valve of the fire hose is generally not opened for use when there is no fire in the surrounding buildings. Therefore, the water valve of the water pipe is very easy to rust locally due to long-term non-use, resulting in manual opening of the valve when it is necessary to open the valve for use. It is very difficult, time-consuming and labor-intensive. Once the fire spreads because the water valve cannot be opened in time, it will cause serious economic losses. In response to this, we propose a fire hydrant box for indoor building fire protection. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: See Figure 1-5 The utility model provides a technical solution: a fire hydrant box for indoor building fire protection. The application is mainly aimed at the fire hydrant box in the prior art. The water valve of the water pipe is very easy to be partially rusted due to long-term non-use, which makes it very difficult to open the valve manually when the water valve needs to be opened for use. It is time-consuming and labor-intensive. Once the fire spreads because the water valve cannot be opened in time, it will cause serious economic losses. The specific scheme is as follows: It includes a main water pipeline 1 and a fire protection box 2. The main water pipeline 1 is connected with a connecting elbow 81, and the connecting elbow 81 is plugged into the fire protection box 2. The lower end of the fire protection box 2 is fixedly installed with a water receiving assembly 8. The water receiving assembly 8 and the connecting elbow 81 are fixedly installed. Through the setting of the connecting elbow 81, it is convenient to transport the inside of the main water pipeline 1 to the water receiving assembly 8.

[0022] See also Figure 1 , Figure 2 and Figure 3 A support plate 1 3 is arranged above the water receiving assembly 8, and a nozzle seat 4 is clamped on the support plate 1 3. The nozzle seat 4 can be arranged for connection and use as needed. A support plate 2 6 is arranged on the right side of the support plate 1 3, and a water pipe belt 5 is sleeved on the support plate 2 6.

[0023] Specifically, the water receiving assembly 8 includes a processing chamber 82, a plug sleeve 9, a plug head 91 and a plug rod 92. The connecting elbow 81 and the processing chamber 82 are fixedly installed, and the connecting elbow 81 and the inside of the processing chamber 82 are connected. A reset spring 93 is sleeved on the inner side of the plug sleeve 9. The reset spring 93 is arranged above the processing chamber 82, and the center line of the reset spring 93 is collinear with the center of the processing chamber 82. The lower end surface of the plug sleeve 9 is provided with a plug rod 92 in an annular shape, and a connection port 7 is provided in front of the processing chamber 82. Figure 3As shown, in the initial state, the return spring 93 is in a compressed state, and the plug rod 92 is stuck directly below the processing chamber 82. At this time, the distance between the plug sleeve 9 and the processing chamber 82 is the smallest, and the plug head 91 blocks the connection port 7, and water does not enter the connection port 7; conversely, after the plug rod 92 is out of the restriction of the processing chamber 82, the return spring 93 can be automatically reset. At this time, the distance between the plug sleeve 9 and the processing chamber 82 is the largest, and the plug head 91 moves upward from the connection port 7, thereby being out of the restriction on the connection port 7, and water can enter the connection port 7.

[0024] Furthermore, a guide slot 83 is provided in an annular shape on the upper end surface of the processing chamber 82, and the plug rod 92 is movably plugged into the guide slot 83. The guide slot 83 is a through slot, and the number of the guide slots 83 and the plug rod 92 is equal. Through the setting of the guide slot 83, it is easy to guide the plug rod 92. Through the guidance of the guide slot 83, the plug rod 92 can be placed in the processing chamber 82, and the plug rod 92 can be rotated to stagger the upper and lower positions of the plug rod 92 and the guide slot 83, thereby facilitating the water connection operation, without any bolt assistance, and convenient operation.

[0025] It is worth noting that the length of the plug 91 is greater than the inner diameter of the connection port 7, and the plug 91 and the plug sleeve 9 are fixedly installed. The corresponding end of the water pipe belt 5 is clamped on the connection port 7, and the side of the water pipe belt 5 away from the connection port 7 is clamped with the nozzle seat 4.

[0026] Working principle: In the fire hydrant box used for indoor building fire protection, in the initial state, the plug sleeve 9 is stuck in the upper end of the processing chamber 82, the return spring 93 is compressed, and the plug head 91 is placed under the processing chamber 82. At this time, the water entering through the main water pipe 1 and the connecting elbow 81 will not enter the connection port 7; when in use, it is only necessary to open the door of the fire protection box 2, and insert the corresponding joint of the water pipe belt 5 into the connection port 7, press the plug sleeve 9, and rotate the plug sleeve 9 so that the plug rod 92 slides out from the guide groove 83. At this time, through the elastic action of the return spring 93, the distance between the plug sleeve 9 and the processing chamber 82 increases, and the plug head 91 moves from bottom to top in the processing chamber 82 and detaches from the connection port 7. The water inside the main water pipe 1 and the connecting elbow 81 enters the processing chamber 82 and enters the connection port 7 and is discharged from the water pipe belt 5. No bolt assistance is required, and installation and disassembly are convenient.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
