Description
Technical field
The utility model relates to level sensor technical field of processing equipment, is specifically related to a kind of water level sensor of washing machine wireline inspection positioning tool.
Background technology
Water level sensor of washing machine is used for the change of sensed water level, and the air pressure produced when its principle is and utilizes water level to rise is delivered on sensor by pipeline, and magnetic core movement change in coil magnetic flux is realized.As the standard universal part of on washing machine, the principle of existing level sensor is all substantially identical, and its theory structure is as follows: divide inner/outer tube by washing machine tub, urceolus has an independent air chamber, aqueous phase in this air chamber and urceolus connects, and keeps water level at grade; The top of air chamber is received on the valve of level sensor by seal tube.When the height of water level in washing machine drum changes, water level in independent air chamber on urceolus also changes thereupon, be sealed in the air pressure to one section of sealing air of sensor diaphragm bottom in urceolus independent air chamber water surface top, O-ring seal flexible pipe, change along with the SEA LEVEL VARIATION in laundry machine barrel.At sensor internal, the diaphragm in sensor is raised by the air pressure that sealing air section provides.Diaphragm in sensor there is a magnetic core support, magnetic core support has a magnetic core, outside magnetic core, be with a coil, magnetic core has one be installed in spring that set screw on housing compresses; When diaphragm is raised, so spring is under pressure and is compressed; When the pressure that diaphragm is lifted to sealing air section and provides equals the elastic force of spring, reach a balance, now magnetic core has a position relative to coil, and coil then can export a frequency values to computer board of washing machine; By above conversion, computer board of washing machine just can judge the water level height of washing machine.
Along with improving constantly of washing machine automaticity, the requirement for all parts of washing machine is also more and more higher.Need constantly to improve, to adapt to the requirement of this change to the equipment of each parts of processing.During as detected level sensor internal wiring, traditional method adopt manually hold level sensor then wiring detect, workload is large, and efficiency is low.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, easy to operate water level sensor of washing machine wireline inspection positioning tool.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of water level sensor of washing machine wireline inspection positioning tool, comprise a square positioning plate, four corners of described positioning plate are provided with a pilot hole, for being fixed positioning plate, described positioning plate is provided with 16 keepers, 16 keepers laterally and vertical on be divided into four rows, for positioning level sensor, described keeper comprises a cylindrical reference column, described reference column front end is provided with locating piece, bottom described reference column and be all connected on positioning plate by screw mandrel bottom locating piece, adopt this kind of connected mode can change keeper at any time, with the needs that the level sensor adapting to different model and size detects.
Described locating piece is " recessed " shape structure, matches with the notch on level sensor.
Described pilot hole inwall is provided with screw thread.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, can be good at being fixed level sensor, facilitates the carrying out of testing, and can not damage level sensor, ensure the quality of product, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of water level sensor of washing machine wireline inspection positioning tool, comprises a square positioning plate 1, and four corners of positioning plate 1 are provided with a pilot hole 2, and pilot hole 2 inwall is provided with screw thread.For being fixed positioning plate 1, positioning plate 1 is provided with 16 keepers, 16 keepers laterally and vertical on be divided into four rows, for positioning level sensor, keeper comprises a cylindrical reference column 3, reference column 3 front end is provided with locating piece 4, and locating piece 4 is " recessed " shape structure, matches with the notch on level sensor.All be connected on positioning plate 1 by screw mandrel bottom reference column 3 He bottom locating piece 4, adopt this kind of connected mode can change keeper at any time, the needs detected with the level sensor adapting to different model and size.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
