The present invention relates to a household sewage pump, in particular to a multipurpose float switch mounting bracket belongs to the technical field of water pumps.
Water pumps can be controlled by float switches, the drop of the liquid level will gradually lose buoyancy to the float switch so that the power is automatically cut off, when the liquid level rises, the float switch is automatically closed by buoyancy of float and the pump is powered on.
There are two kinds of conventional float switch mounting brackets, one is fixed on the pump and another is fixed on the outlet pipe, the two kinds of float switch mounting brackets are not interchangeable, that causes that the scope of the brackets' use is limited and there is a need of improvement.
The technical problem the present invention is to solve is to supply a multipurpose float switch mounting bracket, of which it's optional to the user to fix the float switch onto the water pump or to the outlet pipe, i.e. the accessibility thereof enhanced.
In order to solve the above technical problem, the technical solution of the present invention is provided with a multipurpose float switch mounting bracket, which includes a curved plate and a flat plate, the curved plate is connected to a first end of the flat plate, and two position-limitation strips are arranged on the outer convex surface of the curved plate, the two position-limitation strips are distributed up and down with a distance disposed between them, the flat plate is provided with a first set of mounting holes and a second set of mounting holes, the water pump is provided with a first set of threaded holes which are corresponding to the first set of mounting holes, and the float switch is provided with a second set of threaded holes which are corresponding to the second set of mounting holes, and the curved plate is provided with arc-shaped slots on both edges, the first set of mounting holes are disposed at a second end of the flat plate which is opposite to the first end, the second set of mounting holes is disposed at a back area relative to the first set of mounting holes.
In a preferred embodiment of the present invention, the curved plate and the flat plate are perpendicular to each other.
In a preferred embodiment of the present invention, the curved plate and the flat plate are integrated structures or split structures that made of steel plates, other metallic materials or non-metallic materials.
In a preferred embodiment of the present invention, the connection area between the curved plate and the flat plate is arranged with reinforcement ribs for strengthening.
In a preferred embodiment of the present invention, it also includes a clasping device, a water pipe vertically arranged at the water outlet end of the water pump, wherein the curved plate is attached on the outer wall of the water pipe, and the clasping device hooped on the curved plate and the outer wall of the water pipe, and the clasping device passes the arc-shaped slots and disposed between the two position-limitation strips, and the float switch is arranged on the flat plate via screw bolts go through the second set of mounting holes and the second set of threaded holes.
In a preferred embodiment of the present invention, the curved plate is provided with a punched slot between the two position-limitation strips, and the two position-limitation strips and the curved plate are integrated structures.
In a preferred embodiment of the present invention, the first set of mounting holes and the second set of mounting holes respectively consist of at least two through holes.
In a preferred embodiment of the present invention, the flat plate is arranged on the water pump, the curved plate extends downwards, and the flat plate is secured via screw bolts pass through the first set of mounting holes and the first set of thread holes, and the float switch is secured on the flat plate via screw bolts pass through the second set of mounting holes and the second set of thread holes.
The beneficial effect of the invention is: The invention is provided with a multipurpose float switch mounting bracket, which can fix the float switch onto the water pump by connecting the flat plate of the bracket to the float switch and the water pump respectively with screws. In addition, the curved plate can be fixed on the side of the water pipe by means of the clasping device, and fix the float switch on the flat plate to secure the float switch. The conversion is convenient and the versatility is wide. It can match different sizes of water pipes and has a wide range of applications.
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below. Obviously, the drawings in the following description are merely some embodiments of the present invention. For those who skilled in the art, other drawings may also be obtained based on these drawings without paying any creative work. Therein:
The following is clear and complete description of the technical solutions in the embodiments of the present invention. Apparently, the described embodiments are merely some but not all embodiments of the present invention. All other embodiments obtained by a person who is skilled in the art based on the disclosed embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
Please refer to
A multipurpose float switch mounting bracket, which includes a curved plate 2 and a flat plate 8, the curved plate 2 is connected to a first end of the flat plate 8, the curved plate 2 and the flat plate 8 are perpendicular to each other, the curved plate 2 and the flat plate 8 respectively are integrated steel plate bending structures, which is strong and easily for producing, the connection area between the curved plate 2 and the flat plate 8 is arranged with reinforcement ribs 7 for improving the structural stability and avoiding deformation problems.
On the outer convex surface of the curved plate 2 where is arranged with two position-limitation strips 1, the two position-limitation strips 1 are distributed up and down with a distance disposed between them, the curved plate 2 is provided with a punched slot 3 between the two position-limitation strips 1, the two position-limitation strips 1 and the curved plate 2 are integrated structures, applying the punching process to bend the material out of the punched slot 3 to obtain the position-limitation strips 1, the structure is strong and the producing is easy.
The flat plate 8 is provided with the first set of mounting holes 5 and the second set of mounting holes 4, the first set of mounting holes 5 is located at a first end of the flat plate 8, the second set of mounting holes 4 is located at a relatively hack area of the first set of mounting holes 5. The water pump 12 is provided with the first set of threaded holes which are corresponding to the first set of mounting holes 5. The float switch 11 is provided with the second set of threaded holes which are corresponding to the second set of mounting holes 4. The design makes the connection easy. The first set of mounting holes 5 and the second set of mounting holes 4 respectively consist of at least two through holes.
