Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a mechanical starting valve component of a kitchen fire extinguishing device. Background Art

[0002] The kitchen is a place with extremely high fire hazards because the cooking process involves a variety of high-temperature operations. For example, frying, stir-frying, deep-frying and other cooking methods require the use of open flames or high-temperature heating equipment. There are various flammable items in the kitchen, in addition to cooking oil, there are also food packaging materials, paper, plastic tableware, etc.

[0003] The mechanical starting valve assembly of the fire extinguishing device is a key component in the fire extinguishing system.

A movable groove 304 is formed on the inner wall of the fixing frame 2, and a movable block 305 is slidably connected to the inner wall of the movable groove 304. A rotating shaft 306 is rotatably connected to the inner wall of the fixing frame 2, and a positioning groove 307 is formed on the outer surface of the rotating shaft 306;

[0028] The auxiliary component 8 includes a second screw 801, the outer surface of the second screw 801 is threadedly connected to a lifting block 802, and one side of the lifting block 802 is fixedly connected to a fixing plate 803, one side of the fixing plate 803 is installed with a connecting plate 804, and one side of the connecting plate 804 is fixedly connected to a handle 805, one side of the fixing plate 803 is provided with a fixing groove 806, and the inner wall of the fixing groove 806 is threadedly connected to a fixing bolt 807.

[0029] Through the above technical solution, the grip ring 301 rotated by hand can drive the first screw 302 to rotate while driving the lifting rod 303 to move downward. During the lifting process, the lifting rod 303 will slide in the movable groove 304 through the movable block 305 to maintain stability, so that the lifting rod 303 can extend into the positioning groove 307 to limit the rotating shaft 306, so that the handle 4 on the rotating shaft 306 cannot be rotated, so as to avoid accidentally touching the handle 4 and activating the fire extinguishing device, so as to ensure that the valve can be activated only after a fire occurs and is confirmed, thereby achieving the effect of preventing accidental touch.

[0030] Specifically, a handle 4 is installed on the top of the valve body 1 , and a pressure display 6 is provided on one side of the interface 5 .

[0031] Through the above technical solution, the handle 4 can be rotated to turn on and off the activation of the fire extinguishing device, and the pressure in the bottle body 7 can be detected through the pressure display 6.

[0032] Specifically, the grip ring 301 forms a lifting structure through the first screw rod 302 and the lifting rod 303 , and the external thread of the first screw rod 302 matches the internal thread of the lifting rod 303 .

[0033] The above technical solution facilitates manually rotating the first screw rod 302 to drive the lifting rod 303 to move up and down, so that the lifting rod 303 can move up and down in the fixing frame 2, thereby achieving the lifting effect of the lifting rod 303.

[0034] Specifically, the fixing frame 2 forms a sliding structure through the movable groove 304 and the movable block 305 , and the shape and size of the movable groove 304 match the shape and size of the movable block 305 .

[0035] Through the above technical solution, the lifting rod 303 can drive the movable block 305 to rise and fall synchronously during the lifting process, so that the movable block 305 slides up and down in the movable groove 304, and then the lifting rod 303 can be kept stable by the movable block 305 sliding in the movable groove 304 during the lifting process to prevent the lifting rod 303 from rotating.

[0036] Specifically, the rotating shaft 306 forms a snap-fit ​​structure with the lifting rod 303 via the positioning groove 307 , and the shape and size of the positioning groove 307 match the shape and size of the lifting rod 303 .

[0037] Through the above technical solution, it is convenient for the lifting rod 303 to extend into the positioning groove 307 to limit and fix the rotating shaft 306, so that the rotating shaft 306 cannot rotate, and the handle 4 is rotated by the rotating shaft 306, so that the handle 4 can be locked. When the handle 4 is used, the lifting rod 303 can be raised upward to release the limit fixation of the rotating shaft 306, thereby achieving the effect of controlling the handle 4.

[0038] Specifically, the second screw rod 801 forms a lifting structure through the lifting block 802 and the fixed plate 803 , and the external thread of the second screw rod 801 matches the internal thread of the lifting block 802 .

[0039] Through the above technical solution, it is convenient to manually rotate the second screw 801 to drive the lifting block 802 to move up and down while driving the fixing plate 803 to move up and down, achieving the effect of lifting the fixing plate 803 on one side of the bottle body 7.

[0040] Specifically, the fixing plate 803 forms a fixing structure with the connecting plate 804 through the fixing bolt 807 , and one end of the fixing bolt 807 passes through one side of the connecting plate 804 to be connected to the fixing groove 806 .

[0041] Through the above technical solution, the connecting plate 804 is conveniently installed and fixed to the fixing plate 803 by means of the fixing bolts 807 extending through the fixing groove 806, which is convenient for installation and disassembly, and then the handle 805 is installed on the fixing plate 803, so that the height of the handle 805 can be adjusted.

[0042] Working principle: When using the mechanical start valve assembly of the kitchen fire extinguishing device, first, when releasing the limit of the handle 4, it is only necessary to rotate the grip ring 301 by hand, so that the grip ring 301 drives the first screw 302 to rotate, and the first screw 302 drives the lifting rod 303 to rise upward, so that the bottom of the lifting rod 303 is separated from the positioning groove 307, and the limit fixation of the rotating shaft 306 is released. When limiting the handle 4, it is only necessary to reverse the grip ring 301 to make the lifting rod 303 move downward, and then the lifting rod 303 will extend into the positioning groove 307. 7 is used to limit and fix the rotating shaft 306, and then a fixing bolt 807 is used to penetrate the connecting plate 804 and extend into the fixing groove 806 to be installed with the fixing plate 803, so that the handle 805 is installed on one side of the bottle body 7. When using the fire extinguishing device, the handle 805 can be grasped to lift it, which is convenient for use, and the height of the handle 805 can be adjusted by rotating the second screw 801 to meet different usage requirements. This completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.

[0043] Although the 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 these embodiments without departing from the principles and spirit of the appended claims and their equivalents.
