Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire hydrant for building security. Background Art

[0002] After searching, application number 202121874071.6 discloses a fire hydrant for building security, including a box body, a box door is provided on the rear side of the box body, a placement plate is fixedly connected to the bottom surface of the front wall of the box door, a rotary joint A is rotatably connected to the rear part of the placement plate, a connecting pipe is fixedly connected to the upper part of the rotary joint A, a switch valve A is installed on the upper part of the connecting pipe, a reel is provided on the upper rear side of the switch valve A, and a fire water pipe is wound on the reel.

[0003] During use, a fire hydrant for building security in this patent application is connected to the box door by rotation through the use of a placement plate and a connecting ear, so that the box door can rotate with the middle of the rear end of the box as the center, without obstructing the surroundings, thereby facilitating firefighting work. However, during such use, since the fire-fighting equipment such as the water gun nozzle, fire hose and reel of the equipment are all arranged on the box door, the box needs to leave enough space for the box door and the fire-fighting equipment to rotate and move, which leads to an increase in the volume of the box, which not only reduces the utilization rate of the internal space of the box, but also increases the installation space of the equipment, reducing the practicality of the equipment. For this reason, we propose a fire hydrant for building security. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides a fire hydrant for building security, which has the following beneficial effects:

[0014] 1. A fire hydrant for building security is provided with a positioning mechanism. In the initial state, the first protection box door and the second protection box door are both kept in a vertical state under the action of their own gravity. At this time, the positioning card block at the bottom end of the second protection box door is connected to the inside of the closed positioning card slot on the top wall of the supporting strip, that is, the position of the first protection box door and the second protection box door in the closed state of the device is fixed. When the fire hydrant assembly inside the fire fighting box body needs to be used, the first protection box door can be driven by the operating handle to rotate upward and open to a horizontal state, thereby forcing the second protection box door to drive the positioning card block to move upward away from the closed positioning card slot, releasing the position fixation between the second protection box door and the supporting strip, rotating the second protection box door upward to fit with the first protection box door, and connecting the positioning card block to the inside of the open positioning card slot, that is, the position of the first protection box door and the second protection box door in the open state of the device is fixed. At this time, the first protection box door and the second protection box door are both located above the fire fighting box body, and will not hinder the staff from using the fire hydrant assembly inside the fire fighting box body. The above operation is simple and practical, making the device more convenient to use and improving the practicality of the device.

[0015] 2. The fire hydrant for building security is provided with a guiding mechanism. When firefighters extract the waterproof pipe from the inside of the fire fighting box, the fire fighting water pipe will come into contact with the front side wall of the fire fighting box, and the fire fighting box will roll with the outer wall of the fire fighting water pipe in the extracted state through the guiding roller, thereby reducing the friction resistance between the fire fighting water pipe and the fire fighting box, bringing convenience to the fire fighting work of the firefighters and improving the practicality of the equipment.

[0016] 3. The fire hydrant for building security is configured such that a positioning magnet block is fixedly embedded at the bottom of the positioning card block, and positioning iron sheets corresponding to the position of the positioning magnet block are fixedly embedded on the inner side walls of the closed positioning card slot and the open positioning card slot.
