Detailed description of the invention
Below in conjunction with accompanying drawing, the exemplary embodiment of the present invention is explained, including embodiment of the present invention
Various details are to help understanding, it should they are thought the most exemplary.Therefore, those of ordinary skill in the art should recognize
Knowledge is arrived, and embodiment described herein can be made various changes and modifications, without departing from scope and spirit of the present invention.
Equally, for clarity and conciseness, description below eliminates the description to known function and structure.
Fig. 2 is the schematic diagram of the principle of the rotary limit device of a kind of rotary apparatus according to embodiment of the present invention.As
Shown in Fig. 2, rotary limit device mainly includes base 1, guide rail 2, position limiting slide block 3, instrument slide block 4, connecting rod 5 and two set limits
Position seat, is limit base 6 and limit base 7 respectively.
Guide rail 2 is fixed on base 1, and position limiting slide block 3 is arranged on guide rail 2 and can be along guide rail 2 bidirectional-movement, i.e. at guide rail
Move along a straight line between 2 two ends.Instrument slide block 4 is fixed on connecting rod 5, connecting rod 5 be connected with rotary apparatus (not shown) thus
Translation can be rotated in the plane being parallel to base upper surface under the drive of rotary apparatus.Fig. 2 is top view, rotation therein
Turn the center of circle that the rotating shaft 8 of instrument is the movement locus 10 of instrument slide block 4, connecting rod 5 circle that this track the most inswept surrounds when translation
Face.
Limit base 6 and limit base 7 are separately positioned on guide rail 2 two ends, and are fixed on base 1.Figure show spacing
A kind of concrete structure that seat can use, it includes the housing 61 of limit base, spring 62, guide rod 63.The opening of housing 61 towards
Guide rail 2, is provided with spring 62 in opening, one end of guide rod 63 is connected with spring 62, and the other end is positioned at outside above-mentioned opening, thus
The position limiting slide block 3 that can be moved along guide rail 2 touches, and due to the effect of spring 62, this motion of position limiting slide block 3 is hindered
Only.Here spring can also use other elastomeric elements, such as block rubber etc..Employing elastomeric element can be with buffer limit slide block
Impact to limit base, and the adverse effect that all standing avoiding instrument to rotate brings.
Can have the rib 31 of a projection on position limiting slide block 3, instrument slide block 4 can meet this rib 31 thus and position limiting slide block
3 contact, connecting rod 5 rotate translation time, instrument slide block 4 under the drive of connecting rod 5 according to the dashdotted circus movement rail in figure
Mark moves clockwise, and when instrument slide block 4 touches the rib 31 on position limiting slide block 3, promotes position limiting slide block 3 along guide rail 2
Motion.Fig. 2 shows position limiting slide block 3 contact with limit base 6 (guide rod 63 specifically and in limit base 6 contacts, for signal
Clearly, in a small amount of distance between the limit base 6 in figure and guide rod 63) situation.When connecting rod 5 counterclockwise motion, spacing
Slide block 3 is pushed to limit base 7 and contacts therewith, as it is shown on figure 3, Fig. 3 is a kind of gyroscope according to embodiment of the present invention
The schematic diagram of one duty of the rotary limit device of device.In conjunction with Fig. 2 and Fig. 3 it can be seen that instrument slide block 4 can be complete
Turn over whole circumference, and for shown in position shown in Fig. 2 and Fig. 3 between position, instrument slide block 4 can be from the clockwise and inverse time
Pin both direction is passed through.Therefore use the rotary limit device of embodiment of the present invention, achieving, rotary apparatus is limited
Position is while avoiding one direction to rotate continuously, additionally it is possible to eliminates and rotates dead angle, it is ensured that the omnibearing observation of instrument.
Electronic limit device can also be installed additional on rotary limit device in embodiment of the present invention, close at position limiting slide block
During this electronic limit device, this electronic limit device is triggered, thus cuts off the power supply for rotation of rotary apparatus, makes instrument
Stop the rotation.As it is shown on figure 3, such as electronic limit device 91, electronic limit device 92 are separately fixed on base 1, near leading
The two ends of rail 2, and for position limiting slide block extreme position on guide rail, electronic limit device 91, electronic limit fill
Put 92 closer to the central authorities of guide rail 2, make position limiting slide block 4 trigger electronic limit before touching limit base 6 or limit base 7 respectively
Device 91 or electronic limit device 92.
So far, although those skilled in the art will appreciate that the multiple of the most detailed present invention of illustrate and describing show
Example embodiment, but, without departing from the spirit and scope of the present invention, still can be direct according to present disclosure
Determine or derive other variations or modifications of many meeting the principle of the invention.Therefore, the scope of the present invention is it is understood that and recognize
It is set to and covers other variations or modifications all these.
