Description

Technical Field

[0001] The utility model belongs to the field of irrigation, relates to a water hose, and in particular to a prefabricated interface for a water hose. Background Art

[0002] In the field of irrigation, in order to save water resources and achieve better irrigation effects, micro-spraying belts are often used. The micro-spraying belt is preset with several tiny spray holes, and the high-pressure water flow in the micro-spraying belt is sprayed out from the spray holes to irrigate crops. Several micro-spraying belts are arranged at intervals in the field, and a main water belt is provided to supply water to the several micro-spraying belts. Several interfaces for connecting with the micro-spraying belts need to be provided on the main water belt. The existing method is that multiple short water belts are connected in series through joints to form a long water belt, and the joints are three-way joints, but this method is more troublesome and inconvenient to store. If the method of installing the interface on the side of the water belt is adopted, the interface is generally made of metal or PVC, but the water belt is made of nylon or PE, so it is not convenient to perform mechanical connection between the interface and the water belt in common ways such as threading and welding. Utility Model Content

[0003] In view of the above-mentioned problem, the utility model provides a prefabricated interface which is fixed on a preset hole of a water hose by deforming after being pressed.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is a prefabricated interface for a water hose, including a connecting end, a pressure plate, and a cone end arranged in sequence from top to bottom.

[0005] Preferably, the connecting end, the pressing plate and the cone end are made of PVC, PE or PP and are seamlessly connected as one.

[0006] Preferably, the connecting end is cylindrical and provided with an internal thread.

[0007] Preferably, a plurality of annular water-stop grooves are provided on the lower side of the pressure plate, and the center of the water-stop grooves is on the axial center line of the connecting end.

[0008] Preferably, the diameter of the tapered end gradually increases from top to bottom.

[0009] Preferably, the conical end includes a plurality of folded plates, and the plurality of folded plates are evenly distributed around the axis of the connecting end.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] In the utility model, under high temperature environment, the folding plate is deformed by pressure, so that the folding plate and the pressing plate clamp the side wall of the water hose to realize installation, and the installation method is simple.

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a prefabricated interface for a water hose includes a connecting end, a pressing plate, and a conical end arranged in sequence from top to bottom.

[0022] Furthermore, the connecting end, the pressing plate and the cone end are made of PVC, PE or PP and are seamlessly connected as a whole.

[0023] Furthermore, the connecting end is cylindrical and provided with an internal thread, so as to facilitate connection with a common joint, a two-way joint, a three-way joint or a nozzle.

[0024] Furthermore, a plurality of annular water stop grooves are arranged on the lower side of the pressure plate, and the center of the water stop groove is on the axial center line of the connection end.

[0025] Furthermore, the diameter of the cone end gradually increases from top to bottom.

[0026] Furthermore, the cone end includes a plurality of folded plates, and the plurality of folded plates are evenly distributed around the axis of the connecting end.

[0027] Specifically, the utility model adopts a method of installing a prefabricated interface on the side of the water hose. First, a hole is opened on the side of the water hose, and then the prefabricated interface is inserted into the hole. The pressure plate cannot pass through the hole, and the connecting end is outside the water hose. The prefabricated interface needs to be deformed when applied to the water hose. The above content is the structure before deformation. In order to facilitate the deformation, the connecting end, pressure plate, and cone end of the utility model are made of PVC, PE or PP and are seamlessly connected as a whole. By heating the utility model, these plastic materials are softened to facilitate deformation. Deformation process: Heat the hollow cone end. After heating to a certain temperature, apply plane pressure to the upper and lower ends of the prefabricated interface. Since the diameter of the cone end gradually increases from top to bottom, and the cone end includes a number of folding plates, the folding plates will bend away from the center, so that the folding plates and the pressure plates clamp the side walls of the water hose. In addition, a plurality of water stop grooves are arranged on the lower side of the pressure plate, and the folding plate presses part of the side wall of the water hose into the water stop groove, so that the connection between the prefabricated interface and the water hose is more stable, and the air tightness is improved, preventing water from overflowing from the connection between the prefabricated interface and the water hose.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
