Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, 2 and 3, the utility model provides a double-buckle type current limiting device, which comprises a current limiting main body 1, an elastic adjusting piece 2 for limiting current and a limiting piece 3, wherein a flow adjusting groove 11 for deformation and movement of the elastic adjusting piece 2 and a buckling groove 12 for installing the limiting piece 3 are arranged in the current limiting main body 1, and the bottom of the flow adjusting groove 11 is provided with a water through hole 111;
the limiting part 3 comprises an outer buckling part 31, an inner buckling part 32 and a limiting part 33 for limiting the elastic adjusting part 2 to be separated from the flow adjusting groove 11, wherein two ends of the limiting part 33 are respectively connected with the outer buckling part 31 and the inner buckling part 32;
the fastening groove 12 and the flow rate adjusting groove 11 are respectively provided with a fastening groove 121 for fastening with the external fastening portion 31 and a fastening portion 112 for fastening with the internal fastening portion 32, and the limiting portion 33 is provided with a water passing hole 331 for passing water.
Specifically, referring to fig. 3 and 4, the bottom surface of the flow regulating groove 11 is divided into a normal region 11a and a deformation region 11b from inside to outside, and the normal region 11a and the deformation region 11b are annular regions. The limber holes 111 are arranged at the deformation area, and the elastic adjusting piece 2 is arranged above the normal area 11a and the deformation area 11b, so as to ensure that when water flows through, part of the elastic adjusting piece 2 is impacted and deformed, thereby changing the actual flow area of the limber holes 111 and further realizing the flow limiting function. Accordingly, as the water pressure becomes larger, the amount of deformation of the elastic adjusting member 2 by the pressure deformation becomes larger, and the amount of reduction of the actual flow area of the water passage hole 111 by the blockage of the elastic adjusting member 2 becomes larger, thereby serving to stabilize the water flow rate. Similarly, when the water pressure becomes small, the decreased amount of the actual flow area of the water passage holes 111 is decreased accordingly.
In order to avoid the problem that the water through hole 111 is blocked due to the excessive deformation of the elastic adjusting piece 2 caused by the excessive water pressure, a convex rib 113 for limiting the transverse deformation of the elastic adjusting piece 2 is arranged on the side wall of the flow adjusting groove 11, and the convex rib 113 is arranged corresponding to the elastic adjusting piece 2. Due to the arrangement of the convex rib 113, the maximum deformation of the elastic adjusting piece 2 can be limited to ensure that the water through hole 111 keeps the circulating state, thereby ensuring the water yield and avoiding the situation that the blocking state is always maintained under the high pressure condition. Accordingly, the rib 113 is located above the water passage hole 111, and the bottom area of the rib 113 is smaller than the area of the water passage hole 111.
The external fastening portion 31 is provided with a fastening edge 311 adapted to the fastening groove 121, and the fastening edge 311 is inserted into the fastening groove 121. The limiting member 3 is made of a material having a certain elastic deformation capability, so that the limiting member 3 can be pressed into the fastening groove 12 in a pressing manner, so that the fastening edge 311 can be inserted into the fastening groove 121. Preferably, the retaining member 3 is made of plastic, or the external fastening portion 31 is made of a thin metal sheet.
An inner buckle groove 1121 matched with the inner buckle part 32 is formed in the buckle part 112, and a buckle 1122 for limiting the inner buckle part 32 to be separated is arranged in the inner buckle groove 1121. Therefore, the engaging portion 112 can be pressed into the inner engaging groove 1121, and the engaging portion 1122 can prevent the engaging portion from being disengaged from the inner engaging groove 1121.
Because the elastic adjusting piece 2 mainly carries out anti-falling through the limiting part 33, and both ends of the limiting part 33 are buckled and fixed, the two ends are stably stressed and limited, and the impact of high-pressure water flow can be better resisted.
The stopper 33 includes a plurality of ribs, and the water passing opening 331 is formed between two adjacent ribs. The side wall of the inner fastening groove 1121 is provided with a notch 1123 for the limiting portion 33 to move up and down. That is, the notch 1123 is provided for the rib to move up and down, and simultaneously, the rotation of the limiting member 3 is limited, so as to ensure that the limiting member 3 is in a stationary state, thereby avoiding the occurrence of wear. Meanwhile, the notch 1123 can relatively reduce the rigidity of the inner fastening groove 1121 at that position, so that the inner fastening portion 32 can be more easily fastened into the inner fastening groove 1121.
Further, in order to reduce the vibration amplitude of the limiting member 3 under the impact of high-pressure water flow, a supporting pillar 321 for tightly supporting the inner fastening portion 32 below the buckle 1122 is disposed at the bottom of the inner fastening portion 32, and the supporting pillar 321 is supported on the bottom surface of the inner fastening groove 1121. Therefore, the height of the supporting column 321 can be preset according to the depth of the inner fastening groove 1121, so that the supporting column 321 abuts against the bottom surface of the inner fastening groove 1121 immediately after the inner fastening portion 32 is fastened into the inner fastening groove 1121, thereby fixing the inner fastening portion 32 located in the middle of the limiting member 3, and preventing the inner fastening portion from vibrating up and down.
Preferably, the side surface of the inner fastening portion 32 is an arc surface so as to be fastened into the inner fastening groove 1121. Preferably, the external fastening portion 31 has a ring shape.
The elastic adjusting piece 2 comprises a connecting part connected with the buckling part 112 and an elastic part capable of laterally extending and deforming, wherein the elastic part is arranged on the outer side of the connecting part and positioned above the deformation area 11 b. If the connecting part is a hard ring sleeve to be nested on the fixed buckling part, the elastic part is a rubber ring.
Preferably, the elastic adjustment member 2 is a rubber ring, i.e. the connection and elastic portion is of an integrated structure and made of rubber.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
