The present invention relates to a water hose connector, and more particularly to a protective cover structure for connecting a gardening water hose connector with a spray nozzle.
In general, a conventional gardening spray nozzle is directly connected to a water hose through threads. When in use, the spray nozzle is often pulled, dragged, changed hand over hand, coiled, and so on. As a result, the water hose may be turned reversely, twisted, or bent. In particular, because the range of gardening activities is wide, the angle of rotation and oscillation of the spray nozzle is also relatively large. The twisted and bent water hose may be clogged, so water cannot flow smoothly. Sometime, the joint of the spray nozzle and the water hose may have a crack to cause a leak of water because the water hose is twisted and bent frequently. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
The primary object of the present invention is to provide a protective cover structure to prevent a water hose from bending. The present invention can effectively prevent the amount of water and water pressure from reducing when the water hose is connected with a faucet because the water hose is pulled, dragged and bent. The protective cover structure prevents the water hose from being clogged and further prevents a leak of water or a crack of the water hose. The protective cover structure may function as an auxiliary handle when the water hose is locked to a faucet
In order to achieve the aforesaid object, a protective cover structure of a water hose according to the present invention comprises a water hose connector connected with the water hose, a rigid protective cover mated with an end of the water hose, and at least one sealing member disposed between the water hose and the water hose connector. The water hose connector is an elastic soft sleeve. A front end of the water hose connector is formed with a mating portion for connecting with a spray nozzle. A rear end of the water hose connector is formed with a connecting portion for connecting with the water hose. The protective cover structure further comprises a metallic press member for connecting the water hose with the water hose connector. The water hose connector is formed with a concave step therein. A seat at a rear end of the metallic press member is inserted into the water hose. A front end of the metallic press member is formed with a mating cap having an evaginated rim. The concave step of the water hose connector is movably mated with the metallic press member through the evaginated rim of the mating cap.
Preferably, the mating portion of the water hose connector is inner threads formed at the front end of the water hose connector to mate with the spray nozzle.
Preferably, the water hose connector is made of a plastic material, and the connecting portion is disposed beneath the concave step for insertion of the water hose.
Preferably, the connecting portion is formed with interlaced holes thereon.
Preferably, the rigid protective cover is a copper cover.
Preferably, an outer surface of the mating cap of the metallic press member is formed with an annular flange. An end face of the mating cap is formed with the evaginated rim. A groove is formed between the annular flange and the evaginated rim to mate with the concave step of the water hose connector.
Preferably, the sealing member is an O-shaped sealing ring.
Preferably, the inner threads of the front end of the water hose connector is directly formed in the water hose connector.
Preferably, the front end of the water hose connector is provided with a metallic union having inner threads.
Preferably, the mating portion at the front end of the water hose connector is a mating head having outer threads.
Accordingly, the present invention is provided with the elastic water hose connector, and the water hose connector is formed with the connecting portion to cover the water hose to strengthen the joint strength of the spray nozzle and the water hose so as to prevent the water hose from being bent a great angle relative to the spray nozzle to crack the water hose at the joint. The present invention is further provided with the metallic press member having the mating cap. A rear end of the metallic press member is fixed to the end of the water hose. By using the deformation of the evaginated rim of the mating cap to connect with the water hose connector, the structure of the present invention is simple. The water hose connector movably cooperates with the water hose, such that the spray nozzle can be turned at will relative to the water hose and won't be turned reversely, twisted or bent, preventing the water hose from being clogged and further preventing a leak of water or a crack of the water hose. Besides, when the water hose is locked to a faucet, the elastic water hose connector may function as an auxiliary handle for convenient use and operation.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

The water hose connector 2 is an elastic soft sleeve. A front end of the water hose connector 2 is formed with a mating portion 20 for connecting with a spray nozzle (not shown in the drawings). A rear end of the water hose connector 2 is formed with a connecting portion 23 for connecting with the water hose 1. The elastic water hose connector 2 can enhance the joint strength of the spray nozzle and the water hose 1, preventing the water hose 1 being bent a great angle relative to the spray nozzle to crack the water hose at the joint.
In order to improve the capability of deformation for the water hose connector 2, the connecting portion 23 is formed with interlaced holes 231 to improve the flexibility of the spray nozzle for use.
The water hose connector 2 is made of a plastic material. An inner wall of the mating portion 20 of the water hose connector 2 has inner threads 21 to mate with the spray nozzle and a concave step 22 adjacent to a lower end of the inner threads 21. The connecting portion 23 is disposed in the water hose connector 2 beneath the concave step 22 for insertion of the water hose 1.
The rigid protective cover 3 is fitted on the outer surface of the front end of the water hose 1 to enhance the rigidness of the front end of the water hose 1. The rigid protective cover 3 is a copper cover.
The metallic press member 4 is a metallic bushing. A front end of the metallic press member 4 is formed with a mating cap 41 having an enlarged hole. A rear portion of the metallic press member 4 is formed with a seat 42 inserted into the water hose 1. An outer surface of the mating cap 41 is formed with an annular flange 411. An end face of the mating cap 41 is formed with an evaginated rim 412. A groove 413 is formed between the annular flange 411 and the evaginated rim 412 to mate with the concave step 22 of the water hose connector 2.
The sealing member 5 is installed between the concave step 22 of the water hose connector 2 and the spray nozzle to provide a sealing effect when the spray nozzle and the water hose connector 2 are tightened to press the sealing member 5. Meanwhile, the sealing member 5 is pressed against the evaginated rim 412 of the metallic press member 4 to provide a sealing effect among the water hose 1, the water hose connector 2, and the metallic press member 4. The sealing member 5 is an O-shaped sealing ring.
