Embodiment
See also Fig. 1 and Fig. 2, Fig. 1 is that supervisory device is installed preliminary schematic representation in the embodiment of the invention, and Fig. 2 is the schematic representation of fixing device among the present invention.Supervisory device comprises fixing device 10, monitor unit 20 and first plate body 30.Wherein, fixing device 10 comprises base plate 11, supporting frame 12, cantilever 14 and screw 17.Base plate 11 is provided with first screw 15.Screw 17 has and first screw, 15 corresponding screw rods.Supporting frame 12 is the ㄈ font, is arranged on the base plate 11 side relative with first screw 15, and this supporting frame 12 is provided with pivotal axis 13.Cantilever 14 is sheathed on pivotal axis 13, and can be around pivotal axis 13 rotations.
Supporting frame 12 also is provided with first catch 16 near an end of base plate 11.When cantilever 14 when pivotal axis 13 rotates to first catch, 16 places, first catch 16 will stop cantilever 14 to be further rotated.Cantilever 14 has the first end limit 141 and 142, the first end limits 141, the second end limit are relative with the second end limit 142.Wherein, the distance H 1 of 13 of the first end limit 141 and pivotal axis is less than the distance H 2 of 13 of its second end limit 142 and pivotal axis.
Please refer to Fig. 3 A, Fig. 3 B, Fig. 3 A and Fig. 3 B are the schematic representation and the front views of first plate body in the embodiment of the invention.First plate body 30 has first surface 31 and also has mounting hole 33 and positioning hole 34 with second surface 32, the first plate bodys 30.In the present embodiment, the base plate 11 of fixing device 10 is a circular bottom plate, and positioning hole 34 is a circular port, and the radius of positioning hole 34 is less than the radius of base plate 11.After the cantilever of fixing device 10 14 and supporting frame 12 pass the positioning hole 34 of first plate body 30 from the second surface 32 of first plate body 30, base plate 11 will be resisted against the second surface 32 of first plate body 30.Certainly, the shape of positioning hole 34 and base plate 11 is not limited to circle, as long as satisfy after cantilever 14 and supporting frame 12 pass positioning hole 34 from the second surface 32 of first plate body 30, base plate 11 can be resisted against second surface 32 and get final product.Wherein, first plate body 30 is a ceiling board.
In the present embodiment; When cantilever 14 rotates to first catch, 16 places; And when base plate 11 was parallel to first plate body, the Extreme breadth that is combined in the projection on first plate body 30 of cantilever 14 and supporting frame 12 needed the diameter less than positioning hole 34, can pass positioning hole 34 to guarantee cantilever 14 and supporting frame 12.
In addition, the user in practical operation, can also on base plate 11, set up one equate with positioning hole 34 cross-section areas, cylindrical body that thickness is identical, this moment, supporting frame 12 and cantilever 14 were installed on this cylindrical body, first screw 15 runs through base plate 11 and this cylindrical body.After supporting frame 12 and cantilever 14 pass positioning hole 34; Base plate 11 is resisted against the second surface 32 of first plate body 30; This cylindrical body then is limited in the positioning hole 34, has avoided fixing device 10 to be subjected to displacement in the horizontal direction, thereby has further improved the stability of fixing device 10.
Please refer to Fig. 4, Fig. 4 is the schematic representation of monitor unit among the present invention.Monitor unit 20 comprises that second plate body 21 and hemisphere body 22, the second plate bodys 21 have first surface 211 and second surface 212, and first surface 211 is relative with second surface 212.In the present embodiment, second plate body 21 is roughly circle, and mounting hole 33 is a circular port, and the radius of second plate body 21 is greater than the radius of mounting hole 33, and the radius of hemisphere body 22 approximates the radius of mounting hole 33.
During installation; With first plate body, 30 horizontal positioned; At first the hemisphere body 22 of monitor unit 20 is passed mounting hole 33 from the first surface 31 of first plate body 30; Because the radius of mounting hole 33 approximates the radius of hemisphere body 22, mounting hole 33 is limited in hemisphere body 22 wherein, prevents that monitor unit is subjected to displacement in the horizontal direction.Simultaneously, because the radius of second plate body 21 is greater than the radius of mounting hole 33, this second plate body 21 does not pass this mounting hole, but second surface 212 is resisted against the first surface 31 of first plate body 30.
Next the cantilever 14 of fixing device 10 and supporting frame 12 are passed positioning hole 34 from the second surface 32 of first plate body 30.In order to prevent that cantilever 14 plays pendulum in sending into process; What cause installing is not convenient; Preferably, before cantilever 14 and supporting frame 12 are sent into positioning hole 34, cantilever 14 is rotated near first catch, 16 places; Press with hand near the first end limit 141 of cantilever 14, then cantilever 14 and supporting frame 12 are sent into positioning hole 34.Because the distance H 1 that the first end limit 141 of cantilever 14 and pivotal axis are 13 is less than the distance H 2 of 13 of its second end limit 142 and pivotal axis; If the first end limit 141 of cantilever 14 is a clockwise direction towards the direction of first catch, 16 rotations; After so cantilever 14 being passed positioning hole 34 near first catch 16; Cantilever 14 will rotate counterclockwise, and touch the upper surface 211 of second plate body 21 until the second end limit 142 of cantilever 14, and cantilever stops operating.Again since the radius of base plate 11 greater than the radius of positioning hole 34, base plate 11 does not pass positioning hole 34, but is resisted against on the second surface 32 of first plate body 30.
In the practical operation; The user can adjust the distance of center circle of the radius of second plate body 21, cantilever 14 length, positioning hole 34 and mounting hole 33 etc.; As long as making monitor unit 20, fixing device 10 can install smoothly; And after cantilever 14 and supporting frame 12 passed positioning hole 34, the first surface 211 that cantilever 14 can touch second plate body 21 got final product.
Please refer to Fig. 5 and Fig. 6, Fig. 5 and Fig. 6 are schematic representation and the front views during the supervisory device installation in the embodiment of the invention.After monitor unit installs and fixes; The base plate 12 of fixing device 10 is resisted against the second surface 32 of first plate body 30; Screw 17 is resisted against near first end 141 of cantilever 14; Second end 142 of cantilever 14 is resisted against the first surface 211 of second plate body 21 of monitor unit 20, and the second surface 212 of second plate body 21 is resisted against the first surface 31 of first plate body 30.
During the dismounting monitor unit, only need screw 17 is outwarded winding, cantilever 14 is rotated to first catch, 16 places, remove fixing device 10, can monitor unit 20 be taken out from mounting hole 33.
In the present embodiment; Hemisphere body with monitor unit passes mounting hole earlier; Again through fixing device,, prevent its in the vertical direction displacement on the vertical direction second plate body of monitor unit being limited between the second end limit and ceiling board of cantilever; Fixing to monitor unit and installation and convenient disassembly have been realized.
Compared to existing technology, the present invention uses fixing device that monitor unit is fixed on the ceiling board, can prevent that not only monitor unit is subjected to displacement, and is convenient to install and dismounting, and cost is lower.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
