Further as such scheme is improved, and the outer surface of the Hall metalwork is coated with fluid sealant.
Further as such scheme is improved, and the Hall switch board is fixed on a cover board, is set on the base
Annular seal space is equipped with, the cover board pressing is fixed on annular seal space so that Hall switch board is sealed in annular seal space.
Further as such scheme is improved, and is provided with a positioning pin by the annular seal space, is provided with the cover board
With the location hole of detent fit.
Further as such scheme is improved, and the surrounding of the cover board is coated with fluid sealant.
Further as such scheme is improved, and the upper end of the base is provided with connecting cavity, is set in the connecting cavity
There is upper gear piece, the lower end of the upper cover is provided with lower gear piece, and after upper cover is placed on connecting cavity, rotation is so that upper gear piece is pressed on down
Sealing is realized on gear piece.
The beneficial effects of the utility model:
A kind of Hall subassembly sealing structure of operation handle of the utility model, Hall metalwork are sealed in the accommodating chamber of upper cover
Interior, Hall metalwork is isolated from the outside world after upper cover is fixed with base, and Hall switch board is sealed in base, good seal performance,
Prevent from making moist, erosion of the liquid to part, extends service life when preventing from using.
Brief description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is the part of the embodiment of the utility model, rather than entirely
Portion's embodiment, those skilled in the art without creative efforts, can also obtain according to these attached drawings
Other designing schemes and attached drawing:
Fig. 1 is the utility model preferred embodiment structure diagram;
Fig. 2 is the utility model preferred embodiment decomposition diagram;
Fig. 3 is the utility model preferred embodiment decomposition diagram.
Embodiment
Carried out below with reference to the technique effect of the design of embodiment and attached drawing to the utility model, concrete structure and generation
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is the part of the embodiment of the utility model, rather than whole embodiments, the embodiment based on the utility model, the skill of this area
The other embodiment that art personnel are obtained without creative efforts, belongs to the model of the utility model protection
Enclose.
Referring to figs. 1 to Fig. 3, a kind of Hall subassembly sealing structure of operation handle, includes the base 2 and upper cover of interconnection
1, Hall metalwork 3 is movably set with the base 2, and the outer surface of the Hall metalwork 3 is coated with fluid sealant.On described
The bottom surface of lid 1 is provided with accommodating chamber 4, and after the base 2 is fastened with upper cover 1, the Hall metalwork 3 is located in accommodating chamber 4, institute
State and Hall switch board 5 is also sealed with base 2.Hall metalwork 3 is isolated from the outside world after upper cover 1 is fixed with base 2, parcel
Fluid sealant can also play protection effect, and good seal performance, erosion of the liquid to part, extends service life when preventing from using.
And the installation placement of Hall metalwork 3 is simple to operation, it is not necessary to which instrument is attached, more time saving and energy saving.
The Hall switch board 5 is fixed on a cover board 6, and annular seal space 7 is provided with the base 2, and the cover board 6 is pressed
Conjunction is fixed on annular seal space 7 so that Hall switch board 5 is sealed in annular seal space 7, and the surrounding of the cover board 6 is coated with close
Sealing, Hall switch board 5 are sealed using cover board 6, good seal performance.A positioning pin 8 is provided with by the annular seal space 7, it is described
The location hole 9 coordinated with positioning pin 8 is provided with cover board 6, installation positioning is more precisely convenient.
The upper end of the base 2 is provided with connecting cavity 10, and gear piece 11, the upper cover 1 are provided with the connecting cavity 10
Lower end be provided with lower gear piece 12, after upper cover 1 is placed on connecting cavity 10, rotation so that upper gear piece 11 be pressed on lower gear piece 12 it is real
