Coupler for fire hose with protective member using magnet {Coupler for fire hose with protective member using magnet}

The present invention relates to a coupler for a fire hose equipped with a protective member using a magnet, and more particularly, by preventing the first fastening portion of a first tubular body having a male thread from being exposed to the outside by the protective member, the first fastening For a fire hose equipped with a protective member using a magnet to prevent the negative male thread from being damaged by contact with the floor or structure, and to move and return the protective member to one side and the other side using magnets It's about couplers.

In general, a fire hose coupler is a key part used to extend the length of a fire hose by interconnecting fire hoses to quickly extinguish a fire at the site where a fire has occurred. It plays a very important role in extinguishing a fire.

The couplers provided at the ends of these fire hoses are installed in a male and female pair fastening structure, so when each fire hose is interconnected to the fire site, the coupler having a male thread provided on one side is connected to the female thread of the other fire hose. It is used as a screw fastening method that connects to the formed coupler.

On the other hand, since the couplers for fire hoses made as described above are connected to each other in a screw fastening method, there is a problem in that when the fastening parts of the couplers are damaged by contacting the floor or structure, they are not mutually coupled.

Due to these problems, in recent years, a lot of couplers capable of protecting male threads formed in couplers have been developed, and their structures are also varied and used.

First, looking at the prior art,

Registration No. 20-0487748 (Seal) In the male coupling for fire hoses provided in one hose body and fastened to the female coupling provided in the other hose body, a diameter expansion part coupled to the front end of the one hose body ; A reduced diameter portion having a male threading portion on an outer circumferential surface having a size and shape capable of being fastened to a female threading portion formed on an inner circumferential surface of an enlarged diameter portion provided at the proximal end of a female coupling coupled to the base end of another hose body; And an outer diameter smaller than the outer diameter of the expanding portion and an inner diameter smaller than the inner diameter of the expanding portion, and having an outer diameter larger than the outer diameter of the reduced diameter portion, and integrally comprising a middle tubular portion interposed between the expanding portion and the reduced diameter portion, wherein the A cover tubular portion having a size and shape surrounding the middle tubular portion, the reduced diameter portion, and the tip of the enlarged diameter portion, and having an inner diameter larger than an inner diameter of the expanded portion of the female coupling and smaller than an outer diameter of the enlarged diameter portion of the female coupling; and a spring (S) interposed between the cover tubular portion and the intermediate tubular portion to elastically allow the cover tubular portion to move along the longitudinal direction of the intermediate tubular portion, and one end of the spring is the intermediate tubular portion. It is in contact with a stepped portion provided on an outer circumferential surface between the base end of the portion and the tip of the enlarged diameter portion, and the other end of the spring is in contact with a chin portion protruding radially inward of the cover tubular portion on the inner circumferential surface of the middle portion of the cover tubular portion, The spring always elastically presses the cover tubular portion toward the reduced diameter portion, and is externally mounted in the ring groove formed on the outer circumferential surface of the front end of the intermediate tubular portion to protrude outward in the radial direction of the intermediate tubular portion to prevent the jaw from passing toward the reduced diameter portion Stopper It further includes a ring, and when no external force is applied to the spring, the length of the jaw portion and the stepped portion is such that the male threaded portion of the reduced diameter portion is completely exposed when the cover tubular portion is retracted. Characterized in that It is about the male coupling of the fire hose to be.

Looking at the above conventional technology, it is mainly described that the cover tubular portion can be moved along the longitudinal direction of the intermediate tubular portion using a spring to protect the threaded portion of the male coupling of the fire hose, but the spring In the case of a structure in which the cover tubular portion is moved using the elasticity of the cover tubular portion and the middle tubular portion, there are problems such as gap between the cover tubular portion and the intermediate tubular portion and foreign substances from the outside being caught between each spring. In the case of a structure using a spring, the cover tubular portion When moving the intermediate tubular portion along the longitudinal direction by applying force to the middle tubular portion, there is a problem in that the compressed portion of the spring is different depending on the size of a plurality of force points acting on the cover tubular portion, so that the cover tubular portion shakes and moves.

The present invention has been made to solve the problems of the prior art, and constitutes a plurality of first magnets spaced apart in the same arc on the outer circumferential surface of the other end of the first tubular body, and the other end of the first tubular body. And a plurality of second magnets formed on the inner circumferential surface of the protective member surrounding the first fastening part, spaced apart in the same arc shape at a position corresponding to the first magnet, but having a polarity opposite to that of the first magnet, so that the protective member is Fire hose coupler equipped with a protective member using a magnet that can be moved and returned to one side and the other side along the longitudinal direction of the first tube body to improve problems that occur when using a conventional spring It was completed as a technical task with an emphasis on providing
