The phenomenon that Shi Huiyou is rotated causes internal electronic component damage.
The content of the invention
Technical problem present in for the above-mentioned prior art, this application provides a kind of anti-rotational shell of encoder, after
Lid and its combining structure.
To realize the purpose of this utility model, the utility model provides a kind of anti-rotational shell of encoder, the shell
Non- round boss is provided with, annular seal pocket is provided on the lateral circle surface of the boss, O-ring is installed in the seal groove,
The both sides of the boss are respectively arranged with a shell fixing threaded hole.
Correspondingly, additionally provide a kind of anti-rotational rear cover of encoder, be used in combination with the shell, including with institute
The groove that boss is used in combination is stated, the both sides of groove set a rear cover mounting hole respectively, and screw is fixed through the rear cover
Hole is threadedly coupled with the shell fixing threaded hole.
Correspondingly, a kind of anti-rotational shell of encoder, rear cover combined structure are additionally provided, is provided with including the shell non-
Round boss is provided with annular seal pocket on the lateral circle surface of the boss, O-ring, the boss is equipped in the seal groove
Both sides be respectively arranged with a shell fixing threaded hole；The rear cover is used in combination with the shell, including with it is described convex
The groove that platform is used in combination, the both sides of groove set a rear cover mounting hole respectively, screw through the rear cover mounting hole with
The shell fixing threaded hole is threadedly coupled.
Wherein, the screw is soket head cap screw.
Compared with prior art, the beneficial effects of the utility model are, when use, the groove are buckled in described convex
On platform, the two is connected using screw, the utility model is to become the encoder shell cylinder type mating surface traditional with rear cover
Special-shaped mating surface so that can not relatively rotate between shell and rear cover, has the function that protect decoder internal electronic component.
Description of the drawings

Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It should be noted that " connection " described herein and the word for expressing " connection ", such as " being connected ",
" connected " etc. was both directly connected to including a certain component and another component, and also passed through other component and another portion including a certain component
Part is connected.
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.
As Figure 1-Figure 2, this application provides a kind of anti-rotational shell of encoder, the shell is provided with non-round convex
Platform is provided with annular seal pocket on the lateral circle surface of the boss, O-ring, the both sides of the boss is equipped in the seal groove
It is respectively arranged with a shell fixing threaded hole.
As Figure 3-Figure 4, the application correspondingly additionally provides a kind of anti-rotational rear cover of encoder, with the outer shell phase
It is used cooperatively, including the groove being used in combination with the boss, the both sides of groove set a rear cover mounting hole, spiral shell respectively
Nail is threadedly coupled through the rear cover mounting hole with the shell fixing threaded hole.
As seen in figures 3-6, present invention also provides a kind of anti-rotational shell of encoder, rear cover combined structure, including described
Shell is provided with non-round boss, and annular seal pocket is provided on the lateral circle surface of the boss, is equipped in the seal groove O-shaped
Circle, the both sides of the boss are respectively arranged with a shell fixing threaded hole；The rear cover is used in combination with the shell, bag
Include the groove being used in combination with the boss, the both sides of groove set a rear cover mounting hole respectively, and screw is through after described
Lid mounting hole is threadedly coupled with the shell fixing threaded hole.
When use, the groove is buckled on the boss, is connected the two using screw, the utility model be by
Encoder shell becomes special-shaped mating surface with the traditional cylinder type mating surface of rear cover, so that can not be opposite between shell and rear cover
It rotates, has the function that protect decoder internal electronic component.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
