Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire detection equipment, in particular to a connecting pipe mouth of a fire hydrant pressure detector. Background Art
[0002] Fire hydrants are essential infrastructure in buildings, buildings, shopping malls and other fields. The water supply capacity of fire hydrants directly determines the disaster relief capacity when a fire occurs. In order to promptly detect whether a fire hydrant is blocked, it is necessary to regularly test the water supply pressure of the fire hydrant, and then monitor the fire water supply status of a certain area based on the test results. The existing detection method is to directly connect the detection equipment to the fire hydrant detection outlet, but during the long-term detection process, the stability of the pipe connection part is reduced, which will cause the fire water to overflow during operation, thereby causing a part of the water to be wasted, and sometimes the detection needs to be installed on the fire hydrant for a long time, making this phenomenon more serious. Utility Model Content
[0003] The utility model aims to provide a connecting pipe port of a fire hydrant pressure detector, which is used to overcome the above-mentioned defects in the prior art.
[0004] According to the utility model, a connecting pipe mouth of a fire hydrant pressure detector comprises a hydrant mouth and a detection pipe mouth distributed on the left and right, the mutually close ends of the hydrant mouth and the detection pipe mouth are connected with a sealing gasket, the two sealing gaskets can abut against each other, the mutually close ends of the hydrant mouth and the detection pipe mouth are respectively provided with a connecting cavity and an installation cavity, the connecting cavity is fixed with two vertically symmetrical fixed arc plates, the curvature of the two side ends of the fixed arc plates is greater than the curvature of the middle end of the fixed arc plates, and the installation cavity is fixed with two vertically symmetrical abutting arc plates. The plate has elasticity, and the end face of the abutting arc plate can abut against the inner end face of the faucet port. A fixing ring is fixed on the outer periphery of the faucet port, and two vertically symmetrical clamping rods are slidably connected to the fixing ring. A spring is connected between the fixing ring and the clamping rod. Two vertically symmetrical insertion holes are provided on the outer periphery of the faucet port, and the clamping rod can be inserted into the insertion holes for clamping. Evenly distributed serrations are fixed on the outer peripheries of the two abutting arc plates, and two vertically symmetrical clamping grooves are provided on the side wall of the connecting cavity.
[0005] The beneficial effects of the utility model are:
[0006] The clamping rod plays a role of positioning and clamping, which can help the user to judge whether the installation between the faucet outlet and the detection pipe outlet is complete. At the same time, it prevents the detection pipe outlet from rotating and preventing the faucet outlet and the detection pipe outlet from detaching, thereby improving the stability of the faucet outlet and the detection pipe outlet. The elastic abutting arc plate is pushed open by the fixed arc plate, so that the serrations on the abutting arc plate are clamped with the clamping grooves at the connecting cavity, further improving the impact resistance and stability of the detection pipe outlet, thereby protecting the abutment between the two sealing gaskets and indirectly improving the sealing effect.

Based on the embodiment of 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.
[0017] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time:
[0018] Embodiment 1:
[0019] Reference Figure 1-Figure 7 According to an embodiment of the utility model, a connecting pipe mouth of a fire hydrant pressure detector includes a hydrant mouth 10 and a detection pipe mouth 11 distributed on the left and right. The hydrant mouth 10 and the detection pipe mouth 11 are connected to each other at the ends close to each other with a sealing gasket 16, and the two sealing gaskets 16 can abut against each other. The hydrant mouth 10 and the detection pipe mouth 11 are close to each other. A connecting cavity 20 and an installation cavity 21 are respectively opened. Two vertically symmetrical fixed arc plates 17 are fixed on the connecting cavity 20. The curvature of the two side ends of the fixed arc plate 17 is greater than the curvature of the middle end of the fixed arc plate 17. Two vertically symmetrical abutting The arc plate 18 is elastic, and the end surface of the arc plate 18 can abut against the inner end surface of the faucet port 10. A fixing ring 12 is fixed on the outer periphery of the faucet port 10. Two vertically symmetrical clamping rods 13 are slidably connected to the fixing ring 12. A spring 14 is connected between the fixing ring 12 and the clamping rod 13. Two vertically symmetrical plug holes 15 are provided on the outer periphery of the faucet port 10. The clamping rod 13 can be inserted into the plug holes 15 for clamping. Uniformly distributed saw teeth 19 are fixed on the outer peripheries of the two abutting arc plates 18. Two vertically symmetrical clamping grooves 22 are provided on the side wall of the connecting cavity 20.
[0020] The faucet port 10 is abutted against the detection pipe port 11, and the fixed arc plate 17 and the abutting arc plate 18 are at different angles. The user rotates the detection pipe port 11 to make the abutting arc plate 18 fixedly connected to the detection pipe port 11 rotate circumferentially. Under the elastic action of the abutting arc plate 18 itself, the two abutting arc plates 18 are tilted toward the inner end. During the rotation of the abutting arc plate 18, the abutting arc plate 18 abuts against one end of the left and right ends of the fixed arc plate 17. The abutting arc plate 18 rotates, and under the abutment with the fixed arc plate 17, the abutting arc plate 18 is subjected to the reaction force of the fixed arc plate 17. The fixed arc plate 17 forces the abutting arc plate 18 to overcome its own elasticity and tilt toward the outer end, so that the serrations 19 on the abutting arc plate 18 abut against the clamping groove 22 at the connecting cavity 20. At this time, the two sealing pads 16 abut against each other to prevent water from flowing out. Under the action of the spring force received at the spring 14, the clamping rod 13 is inserted into the plug hole 15 for clamping.
[0021] When disassembling, the user pulls the two clamping rods 13 at the outer ends so that the clamping rods 13 overcome the spring force at the spring 14 and are removed from the insertion hole 15. The user rotates the detection pipe mouth 11, and the abutting arc plate 18 is reset by the elastic force after losing the support at the fixed arc plate 17, and the serrations 19 are disengaged from the clamping groove 22, so that the detection pipe mouth 11 can be removed from the faucet mouth 10.
[0022] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
