Abstract
The utility model discloses a head guide screw tilting mechanism which comprises a driving gear of a tilting motor which can swing up and down and a driven gear which drives a guide screw to rotate; the driving gear and the driven gear are engaged together. The guide screw is provided with a driving nut which can move up and down and prevent the driving nut from moving by a radial position limiting plate; a lever-type driving connection is formed by the driving nut and a camera mounting plate on a camera frame by a connecting rod.
Description
The utility model relates to a kind of novel pivot angle mechanism of The Cloud Terrace, specifically is a kind of screw mandrel pivot angle mechanism of The Cloud Terrace.
The Cloud Terrace is about the delivery vidicon camera is carried out, about to the element of image monitoring, The Cloud Terrace moves to vertically (pivot angle up and down) and level (horizontally rotating) when giving the position of setting earlier, after the actuating motor outage or power on signal of sending by sensitive switch, just change current direction immediately makes the The Cloud Terrace opposite action to terminal organ, The Cloud Terrace repeats above action, can finish swing up and down, the monitoring camera-shooting task of left-right rotation.
The main at present worm and gear transmission conduct pivot angle mechanism up and down that adopts of The Cloud Terrace product both domestic and external, there is following shortcoming in this mechanism:
1. along with the swinging up and down of loads (vidicon camera), the center of gravity position takes place become, the gap between the worm and gear makes the image wow and flutter of vidicon camera.
2. the processing cost height of worm and gear; Volume is big thereby be difficult for hidden and camouflage.
Canine tooth crop rotation pivot angle motion up and down on the small gear drive mounting plate on the minority The Cloud Terrace product employing motor is also arranged, and there is following shortcoming in this mechanism:
1. self-locking performance is poor, is difficult to self-locking when vidicon camera swings to certain position.
2. load capacity is poor, and load disaster location.
The purpose of this utility model is to provide a kind of screw mandrel pivot angle mechanism of The Cloud Terrace, to overcome above-mentioned shortcoming.
Above-mentioned purpose of the present utility model realizes in the following manner:
A kind of screw mandrel pivot angle mechanism of The Cloud Terrace, comprise with upper spider and form active vidicon camera fitting machine and the lower bottom base that is connected, and swing up and down motor and horizontally rotate motor, it is characterized in that swinging up and down the driving gear and the driven wheel engagement that drives the screw mandrel rotation of motor, two ends of described screw mandrel are active respectively to be fixed in the bearing of the bearing of upper spider and following attic base, the transmission nut that moves up and down is set on the screw mandrel, described transmission nut is placed restrictions on its rotation by limiting board radially, and the vidicon camera mounting plate forms Lever type by connecting rod and transmission nut and is in transmission connection.
It is characterized in that having on the described vidicon camera mounting plate at least one mounting hole and can form active the connection with connecting rod.
The utility model has the advantages that significantly, adopt screw mandrel pivot angle mechanism, connecting rod promotes the vidicon camera mounting plate and carries out pivot angle motion up and down, because the lever force-saving principle can reduce power of motor, owing to have the purpose that a plurality of mounting holes can be realized the multiple shelves speed of the upper and lower pivot angle of The Cloud Terrace on the mounting plate; In addition, screw mandrel pivot angle mechanism can dwindle the The Cloud Terrace volume, is easy to camouflage, improves its decorate properties; At last, adopt screw drive to replace worm and gear or gear transmission, easy to process, cost descends, the image wow and flutter phenomenon when having overcome the camera photography monitoring again.
The utility model is described in further detail below with reference to drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, the utility model comprises driving gear 2 that is arranged on the swing angle electric up and down 1 on the upper spider 14 and the driven gear that drives screw mandrel 34 engagements, two ends of described screw mandrel 3 are active respectively to be fixed in the bearing of the bearing of upper spider 1 and following attic base 10, the transmission nut 5 that moves up and down is set on the screw mandrel 3, described transmission nut 5 usefulness radially limiting board 6 are placed restrictions on its rotation and can only be moved up and down, and form by the connecting rod 15 that is connected with transmission nut 5 and vidicon camera mounting plate 7 on being arranged at upper spider 14 that Lever type is active to be connected, when transmission nut 5 moves up and down, drive the pivot angle motion of mounting plate 7 by the transmission of connecting rod 15, a plurality of mounting holes can be arranged to reach different pivot angle speed on the described mounting plate 7, as shown in Figure 1, four mounting holes are arranged, can reach four different pivot angle speed.When pivot angle position-limited nail 8 places of transmission nut 5 ascending motions on being arranged at casing 16, terminal (not shown) changes the current direction of motor immediately, makes screw mandrel 3 counterrotatings and transmission nut 5 down moves.
Horizontally rotate motor 9 and be arranged at down on the attic base 10, the driving gear that horizontally rotates 11 and fluted disc 12 engagements horizontally rotate the action of motor 9, by being arranged at down horizontal position-limited nail 13 on the attic base 10 by terminal (not shown) control action direction.
The foregoing description only for illustrative purposes, protection domain of the present utility model will embody in claims.
Claims (2)
1. the screw mandrel pivot angle mechanism of a The Cloud Terrace, comprise with upper spider and form active vidicon camera fitting machine and the lower bottom base that is connected, and swing up and down motor and horizontally rotate motor, it is characterized in that swinging up and down the driving gear and the driven wheel engagement that drives the screw mandrel rotation of motor, two ends of described screw mandrel are active respectively to be fixed in the bearing of the bearing of upper spider and following attic base, the transmission nut that moves up and down is set on the screw mandrel, described transmission nut is placed restrictions on its rotation by limiting board radially, and the vidicon camera mounting plate forms Lever type by connecting rod and transmission nut and is in transmission connection.
2. screw mandrel pivot angle according to claim 1 mechanism, it is characterized in that having on the described vidicon camera mounting plate at least one mounting hole can form active the connection with connecting rod.
