Description
Technical field
The present invention relates to sealing mechanism, particularly relate to a kind of sealing mechanism of sensor disk.
Background technology
In recent years, have the miniaturization of higher protection level, economical sensor disk, day by day become the active demand of more and more user, this, just to the encapsulating method of sensor disk, proposes higher requirement.Traditional sensor disk design of Sealing Structure, can adopt the interference fit formed by O RunddichtringO and housing usually, as the encapsulating method of main body and housing joint; And adopt the parts such as terminal clamp tight coupling, water joint, rubber bushing, as the encapsulating method of housing outlet; And the sealing often ignored for output shaft part.
Because diameter exists
following little, microsensor dish, in order to save installing space, the irregularly shaped design of the many employings in periphery, this just makes it cannot use O RunddichtringO, and also just difficulty meets higher requirement of shelter.On the other hand, due to the restriction of the conditions such as sensor disk inner space, user installation space, cable outlet position cannot use as terminal clamp tight coupling, water joint, rubber bushing etc. have the parts of protective action.And the mode fixing cable completely by injecting glue filling sensor dish outlet known at present, owing to filling 1 ~ 2 face of a glue often attached sensors dish body, adhesion is little, the tension force value of cable is made to only have 3 ~ 4kgf, cable pullled or root bending time easily get loose, affect protection effect, this just makes the encapsulation scheme of outlet, becomes the another obstacle that high protection miniaturized sensors dish manufactures and designs.And at present for the protection under the non-operating state of the sensor disk such as assembling, accumulating, also uncared-for often.
For sensor disk, dust and impurity can make the accurate device of its inside be polluted, thus affect the Stability and veracity of signal output, so higher protection, for the normal operation of sensor disk, are very important
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of sealing mechanism of sensor disk, restricting by the factor such as structure, space for solving high protection, miniaturized sensors dish sealing means in prior art, causing the problem of sealing difference.
For achieving the above object and other relevant objects, the invention provides a kind of sealing mechanism of sensor disk, comprising:
Cover plate, sensor disk and O shape are enclosed; The side of described cover plate is provided with ring groove, and this ring groove is T-shaped; The center of described cover plate is provided with the through hole running through signal wire; described sensor disk is arranged on the side being provided with ring groove by through hole; O shape circle is positioned in described ring groove; and between this sensor disk and cover plate, being also provided with the fastening bolt of fixation, the opposite side of described cover plate is provided with the protective cover be bolted.
Preferably, also comprise switching place, described switching place is secured by bolts on the cover plate in protective cover.
Preferably, be also provided with O shape between described cover plate and described switching place to enclose.
Preferably, described cover plate, described sensor disk and described O shape are enclosed as concentric circles.
Preferably, described cover plate keeps to the side and is partly provided with the mounting hole of securing cover plate.
Preferably, on the position of mounting hole, groove is provided with at described cover plate.
As mentioned above, the sealing mechanism of sensor disk of the present invention, has following beneficial effect:
By arranging T-shaped ring groove, adding O shape circle and the contact area in this ring groove, improve its sealing effectiveness, meanwhile, sealing mechanism structure is simple, is easy to install.
