[0002] Fire hydrants are a type of fixed firefighting tool, mainly used to control combustibles, isolate combustion-supporting materials, and eliminate fire sources. Fire hydrants are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire water supply network to extinguish fires. They can also be directly connected to water hoses and water guns to discharge water for firefighting. They are one of the important firefighting facilities for fighting fires. In order to improve the firefighting effect, double-valve double-outlet fire hydrants were invented. However, the existing double-valve double-outlet fire hydrants still have the following disadvantages:

DETAILED DESCRIPTION

[0023] In the description of the present utility model, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present utility model. The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0024] See also Figures 1 to 6 The utility model preferably provides a technical solution: a double-valve double-outlet type fire hydrant, comprising: a fire hydrant body 1, two outlet valve assemblies 3 arranged on the top of the fire hydrant body 1, each outlet valve assembly 3 comprises a tank body 301 rotatably connected to the top of the fire hydrant body 1 and communicated with the fire hydrant body 1, and a water outlet 302 arranged on the side wall of the tank body 301, and also comprises a valve body 303 installed on the fire hydrant body 1, and the valve body 303 is used to control the opening and closing of the water outlet 302; a mounting frame 4 is also arranged on the top of the fire hydrant body 1, and a worm gear assembly 5 is arranged on the mounting frame 4, and the worm gear assembly 5 is used to adjust the exposed angle of the water outlet 302 where the two outlet valve assemblies 3 are located; and also comprises an anti-accidental touch assembly 6 arranged on the top of the mounting frame 4, and the anti-accidental touch assembly 6 is used to lock the position of the two valve bodies 303.

[0025] In the present application, two outlet valve assemblies 3 arranged on the top of the fire hydrant body 1 are rotatably connected thereto, and the mounting frame 4 on the top of the fire hydrant body 1, on which the worm gear assembly 5 is arranged, functions to drive the rotation of the two outlet valve assemblies 3. The design is based on the structural characteristics of the outlet valve assembly 3, that is, the outlet valve assembly 3 is composed of a tank body 301, and a water outlet 302 and a valve body 303 on the tank body 301, and the valve body 303 is composed of a valve core inside 301 and a valve stem on the top. Therefore, when the worm gear assembly 5 is running, the position of the water outlet 302 can be switched, thereby realizing the switching of the storage state and the working state of the outlet valve assembly 3, such as Figure 1 , 2 as well as Figure 3 The highlight of this design is that when the device is in the storage state, Figure 1 , 2 As shown in the state, the water outlet 302 is in the retracted state at this time. This design not only reduces the use space occupied by it, but also makes it impossible for the water outlet 302 to be connected to an external water pipe, thereby reducing its abuse. When the device is in the working state, the water outlet 302 where the opening valve assembly is located is exposed, and its exposure angle is adjustable, so as to adjust the connection angle between it and the external water pipe, thereby reducing the occurrence of external water pipe distortion. Figure 3 As shown, this state facilitates the connection between the water outlet 302 and the external water pipe;

[0026] In addition, the anti-accidental touch component 6 arranged on the top of the mounting frame 4 further locks the position of the valve body 303 when the device is in the storage state, thereby reducing the risk of the opening valve component being activated due to accidental touch, thereby ensuring the safe use of the device.

[0027] The utility model, through the arrangement of the worm gear assembly 5, realizes the position shift of the opening valve assembly, and further realizes the switching of the water outlet 302 between the retracted state and the exposed state. When the water outlet 302 is in the retracted state, the usable space occupied by it is reduced, and when the water outlet 302 is in the exposed state, it is convenient to adjust the connection angle between it and the external water pipe, thereby reducing the distortion of the external water pipe. In addition, through the arrangement of the anti-accidental touch assembly 6, the risk of the opening valve assembly being activated due to accidental touch is further reduced, thereby ensuring the safe use of the device.

[0028] Furthermore, a rotating sealing ring is provided at the connection between each tank body 301 and the fire hydrant body 1 to improve the sealing performance of the connection between the fire hydrant body 1 and the tank body 301 where the opening valve assembly is located.

[0029] Furthermore, the worm gear assembly 5 includes two mounting rods 501 rotatably connected to the two ends of the mounting frame 4, and a worm body 502 fixed to the opposite ends of the two mounting rods 501; it also includes a worm wheel body 504 respectively fixed to the outer walls of the two tank bodies 301, and the worm wheel body 504 is meshed with the worm body 502.

[0030] like Figure 1 , 4 As shown, the worm gear assembly here is an existing mature technology, which is often used to transmit motion and power between two staggered axes. The worm wheel and the worm are equivalent to the gear and the rack in their middle plane, and the worm is similar to the shape of the screw. Since the worm wheel body 504 is meshed with the worm body 502, it is worth explaining here that: it is known that when the worm body 502 rotates, the two worm wheel bodies 504 can be driven to rotate, thereby realizing the position transfer of the tank body 301 and the water outlet 302 on the tank body 301, and it has self-locking properties. When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism worm gear assembly has self-locking properties and can achieve reverse self-locking, that is, the worm wheel can only be driven by the worm, and the worm wheel cannot be driven by the worm. In this application, its reverse self-locking property can be used for self-locking of the water outlet 302 position, which is convenient for improving the stability during work.

[0031] Furthermore, one end of one of the mounting rods 501 away from the worm body 502 passes through a through hole provided in the side wall of the mounting frame 4 and is fixed with a handle 503, such as Figure 1 , 4 As shown, the arrangement of the handle 503 here facilitates driving the worm gear assembly 5 .

[0032] Furthermore, the anti-accidental-touch component 6 includes a support rod 601, and a support sleeve 602 fixed to the side wall near the top of the support rod 601, and slide rails 603 are respectively arranged at both ends of the support sleeve 602, and a slider 604 is arranged inside the slide rails; it also includes a support bar 609 fixed on the top of each slider 604, and plug-in components are respectively arranged between the two support bars 609 and the two valve bodies 303; a spring 607 is also connected between each support bar 609 and the support sleeve 602, and the spring 607 is used to reset the support bar 609.

[0033] like Figure 5 , 6 As shown, two slide rails 603 are arranged on opposite sides of the support sleeve 602, and support bars 609 are fixed on the top of the sliders 604 therein. At the same time, plug-in components are respectively arranged between the two support bars 609 and the two valve bodies 303, and the springs 607 arranged between each support bar 609 and the support sleeve 602 are cooperated to realize the position limitation of the two valve bodies 303.

[0034] Furthermore, each group of plug-in components includes an insertion strip 606 arranged outside the support strip 609 and a plug-in portion 608 arranged on the valve body 303, and the plug-in portion 608 includes a connecting portion and a socket portion at the bottom of the connecting portion, and the socket portion is adapted to the insertion strip 606.

[0035] like Figure 2 , 5 As shown in FIG. 6 , when the two insert strips 606 are connected to the insert hole parts where the two insert parts 608 are located, the positions of the two valve bodies 303 are locked, and when the two are separated, the two valve bodies 303 are unlocked, thereby facilitating the position transfer of the water outlet 302.

[0036] Furthermore, two symmetrically distributed shifting blocks 605 are fixedly mounted on the top of the two support bars 609, and each shifting block 605 is L-shaped.

[0037] like Figure 6 As shown, this design facilitates moving the two support bars 609 with one hand, thereby achieving synchronous disengagement or connection of the two insertion bars 606 and the two insertion parts 608 .

[0038] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection. There are many ways of detachable installation, for example, it can be through the method of plug-in and snap-fit, or through the method of bolt connection, etc.

[0039] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
