Description

Technical Field

[0001] The utility model relates to the technical field of indoor fire hydrants, in particular to an indoor fire hydrant. Background Art

[0002] A fire hydrant is a fixed fire-fighting facility, whose main function is to control combustibles, isolate combustibles, and eliminate ignition sources. Indoor fire hydrants are generally installed in indoor fire hydrant boxes, and are commonly used in factories, warehouses, high-rise residential buildings, etc. When using an indoor fire hydrant, first open the fire hydrant door, press the alarm button, and then one person connects the gun head and the water hose and aims at the fire, and the other person connects the other end of the water hose to the aluminum mouth of the hydrant head, and opens the valve to spray water. At present, the valve stem at the fire hydrant valve is switched on and off by turning the turntable, but after the turntable is turned and adjusted, there is no fixed structure, and the turntable is prone to automatic slight rotation, which will affect the accuracy of the regulating valve stem and is not convenient for adjusting and using the fire hydrant. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the above technical defects and provide an indoor fire hydrant, wherein the turntable has a fixed structure.

[0004] In order to solve the above technical problems, the technical solution provided by the utility model is: an indoor fire hydrant, including a fire hydrant body, a valve housing is provided on the fire hydrant body, a rotating shaft is provided on one side of the valve housing, a turntable is provided on the rotating shaft, an annular rotating rod is fixedly connected to one side of the turntable, an annular rotating groove matching with the annular rotating rod is provided in the valve housing, a guide plate arranged oppositely is fixedly connected to the annular rotating rod, annular grooves matching with the guide plate are provided on both sides of the annular rotating groove in the valve housing, and a fastening nut is threadedly connected to the annular rotating rod on one side of the valve housing.

[0005] The advantages of the utility model compared with the prior art are: when using the fire hydrant body, it is necessary to rotate the turntable to open the valve in the valve housing, and after rotating the turntable, tightening the fastening nut can fix the position of the turntable, thereby preventing the turntable from automatically rotating and affecting the use of the fire hydrant body, and the turntable has a fixed structure to prevent self-rotation.

[0006] As an improvement, the fastening nut is fixedly connected to an extension rod arranged opposite to each other, and the extension rod is provided with anti-slip grooves, so that grasping the extension rod facilitates rotating the fastening nut. The anti-slip grooves can increase the friction between the human hand and the extension rod, thereby making it easier for the human hand to grasp the extension rod.

[0007] As an improvement, a non-slip gasket matching the valve housing is adhered to one side of the fastening nut, which can increase the friction between the fastening nut and the valve housing when tightening.

[0008] As an improvement, a rotating handle is rotatably provided on the turntable, and a rubber sleeve is sleeved on the rotating handle to facilitate the rotation of the turntable. The rubber sleeve can improve the comfort of the user's hand when holding the rotating handle.

[0009] As an improvement, the inner wall of the annular groove fits with the surface of the guide plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] As shown in the figure: 1. Fire hydrant body; 2. Valve housing; 3. Turntable; 4. Rotating handle; 5. Rotating shaft; 6. Annular rotating rod; 7. Annular rotating groove; 8. Annular groove; 9. Fastening nut; 10. Extension rod. DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0015] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 , an indoor fire hydrant, comprising a fire hydrant body 1, a valve housing 2 is provided on the fire hydrant body 1, a rotating shaft 5 is provided on one side of the valve housing 2, a turntable 3 is provided on the rotating shaft 5, a rotating handle 4 is rotatably provided on the turntable 3, a rubber sleeve is sleeved on the rotating handle 4 to facilitate the rotation of the turntable 3, and the rubber sleeve can improve the comfort of the user's hand when holding the rotating handle 4, an annular rotating rod 6 is fixedly connected to one side of the turntable 3, an annular rotating groove 7 cooperating with the annular rotating rod 6 is provided in the valve housing 2, a guide plate arranged oppositely is fixedly connected to the annular rotating rod 6, and annular grooves 8 cooperating with the guide plate are provided on both sides of the annular rotating groove 7 in the valve housing 2, and the inner wall of the annular groove 8 is in contact with the surface of the guide plate.

[0016] Combined with Figure 2 and attached Figure 3The annular rotating rod 6 is threadedly connected with a fastening nut 9 on one side of the valve housing 2, and an extension rod 10 arranged oppositely is fixedly connected to the fastening nut 9. The extension rod 10 is provided with anti-slip patterns, and it is convenient to rotate the fastening nut 9 by grasping the extension rod 10. The anti-slip patterns can increase the friction between the human hand and the extension rod 10, thereby making it easier for the human hand to grasp the extension rod 10. An anti-slip gasket that cooperates with the valve housing 2 is adhered to one side of the fastening nut 9, which can increase the friction between the fastening nut 9 and the valve housing 2 when tightening.

[0017] When the utility model is implemented in practice, when it is used, when the fire hydrant body needs to be used, the turntable needs to be rotated to open the valve. Specifically, when the turntable is rotated, the annular rotating rod will rotate in the annular rotating groove as the turntable rotates, and the guide plate will also rotate in the annular groove. When the turntable rotates, the extension rods on both sides are grasped to rotate the fastening nuts, so that the fastening nuts can be tightened to a state of being close to the valve housing. The fastening nuts are close to the valve housing and the annular rotating rod fixing rod can be fixed in the annular rotating groove, so that the turntable can be fixed, thereby preventing the turntable from rotating automatically.
