Abstract
The utility model relates to an antenna limit mechanism for a satellite TV receiving system, more particularly relates to a limit mechanism of any rotary angle (positive and negative, large and small). The utility model consists of a pair of speed increasing transmitting wheels 1/3, a small-pitch screw 4, a traveling nut 5, a sliding contact pin head 6, the spacing baffles 7, 8 or the electrical switches 9, 10. The utility model is suitable for the spacing of any angle of the rotary mechanism and particularly is suitable for the antenna spacing of positive inversion with the rotary angle larger than plus or minus 180 DEG. The utility model has simple structure and has low cost and is reliable and is easy to be implemented.
Description
One, technical field:
The utility model belongs to the communications field, relates to a kind of position-limit mechanism of satellite signal receiving antenna control rotation.
Two, background technology:
The satellite earth antenna that rotates need be spacing in a certain anglec of rotation, if do one-way movement, spacing then being not difficult realized in 360 °, but surpass 360 ° of then general mechanism more complicated; For doing forward and reverse rotation, require≤± 180 ° spacing also being easy to of angle realize, but particularly then be difficult to simple realization, because the locating part of both direction can interfere in the different directions rotation greater than 360 ° spacing greater than ± 180 °.
Three, summary of the invention:
In order to solve the problems referred to above that exist in the satellite earth antenna rotation, the utility model provides a kind of antenna position-limit mechanism of any rotation angle size.
The utility model is realized by following technical scheme.A bull wheel 1 that fixes with the antenna rotating shaft is arranged, bull wheel 1 drives steamboat 3 by driving member 2 and rotates with fine pitch screw rod 4 speedups that steamboat 3 is connected, on the nut 5 that moves about on the screw rod 4 radial peg 6 is arranged, in the sliding tray 11 that radial peg 6 is inserted between two postive stop baffles 7,8, electric limit switch 9,10 can be arranged on the postive stop baffle.
The utility model is simple in structure, reliable operation, with low cost, is easy to realize.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 drives the structural representation of the screw rod and the nut work of moving about for steamboat.
Embodiment:
Referring to Fig. 1, when adjusting antenna direction, drive bull wheel 1 simultaneously by motor-driven antenna rotating shaft and rotate, drive steamboat 3 by driving member 2 and rotate with fine pitch screw rod 4 speedups that are connected on the steamboat 3.
Referring to Fig. 2; in the sliding tray 11 that the radial peg 6 on the nut 5 of moving about is inserted between two postive stop baffles; when steamboat 3 drives screw rod 4 rotations; the nut 5 of moving about on the screw rod 4 moves as straight line; touch when giving the postive stop baffle 9 established or 10 when the nut 5 that moves about moves to radial peg 6 above it, the nut 5 that moves about can not move again, makes steamboat 3, driving-belt 2, bull wheel 1 and antenna rotating shaft, motor all can not rotate again; this moment, motor cut off the power supply automatically because of overload protection is arranged, thereby antenna is stopped operating.
For the motor that does not have overload protection, what then install on baffle position is limit switch.When the radial peg 6 that has the contact effect concurrently arrives electric limit switch 9 or 10 touching switches, cut off motor power, antenna stops operating, and realizes spacing.This limit switch promptly can be an impact switch, also can be the progressive switch of non-collision.
For the motor that overload protection is arranged is carried out duplicate protection; electric limit switch 9 or 10 are housed on postive stop baffle 7,8; when the radial peg 6 that has the contact effect concurrently arrives baffle plate; promptly owing to the nut 5 that moves about can not move again; make steamboat 3, conveyer belt 2, bull wheel 1 and antenna rotating shaft, motor all can not rotate again, motor is cut off the power supply automatically because of overload protection is arranged, thereby again because the radial peg 6 electric limit switches 9 of touching or 10 cut off motor powers; antenna stops operating, and realizes spacing.
According to the needs of the anglec of rotation, the position of postive stop baffle 7,8 and switch 9,10 is adjustable.If the spacing of postive stop baffle 7,8 and switch 9,10 is big, then Kong Zhi rotational angle is big, otherwise little as spacing, and then Kong Zhi rotational angle is little.Because all there are postive stop baffle 7,8 or limit switch 9,10 in the sliding tray both sides, then satellite antenna is done can realize when positive and negative both direction rotates spacing at any angle simultaneously.
The driving member 2 that connects bull wheel 1 and steamboat 3 can be a driving belt, also can be gear.
