Abstract
The invention discloses a rotating and locking protection device comprising a fixed structure and a rotating structure. Fixing feet are arranged on two sides of the fixed structure and are provided with rotating ports and limiting grooves, and anti-slip bosses are arranged in the limiting grooves. The rotating structure comprises a rotating boss and a limiting boss adopting the limiting grooves as a moving track. Since the anti-slip bosses are arranged in the limiting grooves, when a protection cover is opened, the limiting boss adopting the limiting grooves as the moving track is clamped in the limiting grooves through the anti-slip bosses so as to prevent the protection cover to slip and close, accidentally injures are eliminated, and operation complexity and false operation rate of control equipment can be reduced effectively.
Description
Technical field
The present invention relates to a kind of rotary fastening protector, particularly a kind of rotary fastening protector that prevents its landing in the time that rotational structure is opened.
Background technology
The rotational structure that rotary fastening protector comprises fixed structure and is interlocked with fixed structure, can be used in the protection of change over switch operating handle.Fixed structure can be used as the mounting panel of change over switch, for change over switch is installed; Rotational structure can be used as the protective cover of change over switch operating handle, can be fastened on fixed structure.In the time that protective cover and mounting panel are interlocked, the change over switch operating handle being arranged on mounting panel is just opened with external environment is isolated, thereby prevents entering of sand and dust or steam, is conducive to the steady operation of change over switch.
In the time of operation change over switch, operator need to open protective cover.Although existing protective cover is also provided with anti-closure measures, complex structure occupies space larger, on the integrated control appliance of miniaturization, is just restricted.And the protective cover of opening in the time of operation easily hinders operation or injures operator.In addition, integrated control appliance has multiple change over switches, in order to operate different control circuits, need to repeatedly open protective cover, and the loaded down with trivial details degree that this not only can increase operation also can increase the probability of misoperation.
If give rotary fastening protector the additional less outside anti-slip facility that takes up room, both can increase cost, be unfavorable for that again control appliance develops to miniaturization.
Summary of the invention
The present invention carries out in order to address the above problem, and object is to provide a kind of rotary fastening protector with inner anti-slip structure.
To achieve these goals, the present invention has adopted following structure:
The invention provides a kind of rotary fastening protector, comprise fixed structure and rotational structure, it is characterized in that: respectively there is an angle both sides of described fixed structure, described angle is provided with a rotation mouthful, the surrounding of described rotation mouthful be provided with one with the arc-shaped limit groove of the described rotation mouthful concyclic heart, described stopper slot is used for limiting the maximum anglec of rotation of described rotational structure; On described rotational structure, have one with the concave station of described angle tabling, on described concave station, there is rotation boss and a positive stop lug boss being fastened in described stopper slot and taking described stopper slot as movement locus being interlocked with described rotation mouth, described rotation boss and described positive stop lug boss and described rotational structure are integrally formed, and are provided with at least one anti-skidding boss for stoping described positive stop lug boss to move in described stopper slot in described stopper slot.
In addition, in above-mentioned rotary fastening protector, can also have such feature: described rotation mouth is uncovered, the center of circle of described rotation mouth is to open wide angle α with the angle of the line of two open-mouths of described rotation mouth, and 0 ° of < α≤82 °.
In addition, in above-mentioned rotary fastening protector, can also there is such feature: described rotation mouth is for remaining silent.
Further, in above-mentioned rotary fastening protector, can also there is such feature: the two ends of described stopper slot are 90 °～140 ° with the angle that the line in the center of circle of described rotation mouth becomes.
Further, in above-mentioned rotary fastening protector, can also there is such feature: in described stopper slot, being provided with a plurality of anti-skidding boss, is 0 °～120 ° for making the stable open angle of protective cover.
Invention effect and effect
Rotary fastening protector of the present invention has following technique effect:
Because rotary fastening protector of the present invention is provided with at least one anti-skidding boss in stopper slot, after protective cover is opened, positive stop lug boss taking stopper slot as movement locus can be stuck in stop motion in stopper slot by anti-skidding boss, thereby stop the landing closure of protective cover, so accidental injury accident can not occur rotary fastening protector of the present invention, can reduce the complex operation degree of control appliance and the probability of misoperation.
