Abstract
The utility model which relates to a turning base of a satellite antenna comprises a motor, a gear set, a worm, a worm wheel, a pipe body base and a pipe body. The worm wheel which is provided with a bearing hole is provided with a direction zero-set switch and an angle induction switch inside. A base axle hole which is correspondingly arranged on the pipe body base is provided with a notch on the edge. A plurality of inserting holes are arranged on the pipe body base out of the base axle hole for selecting an inserting piece. When the worm wheel turns, the angle induction switch moves and reaches the left and the right inserting pieces to control the turning angle within a set scope. The direction can be known from zero-set parameters, and the precision and convenient control of the satellite antenna angle can be realized through the contact and separation of the notch and the direction zero-set switch.
Description
The utility model relates to a kind of satellite antenna swivel base, relates to the worm gear on the satellite antenna swivel base or rather.
At present, the American-European satellite antenna support body that is extensive use of a kind of rotatable control receiving angle is intended to make and collects different orbiter channels, can be more accurate, clear.And because satellite antenna supports and control whole dish-shaped disk body rotation with swivel base, therefore how to adapt to different decorating positions and angle, provide Control Parameter accurately to set angle and the direction that receives signal to controller, the emphasis that has just become the control of satellite antenna support body to rotate to control this swivel base.
The swivel base structure that tradition is used is that magnetic reed switch is set, as being the disclosed structure of utilizing inductive switch in 8821950 by the Taiwan number of patent application, with the left and right anglec of rotation of interpretation satellite antenna frame and the parameter that makes zero.But the magnetic reed switch that tradition is used because of switch shrapnel elastic fatigue after frequent the use, can cause loose contact, is provided with mutually with magnet in addition, is made as at the magnetic line of force by mistake and has the problem that can not move again when parallel.
By the traditional structure shown in Fig. 1, Fig. 2, be that little Extendible flake directly is set on worm gear, the left and right limit inductive switch of when worm gear rotates, conflicting, rotate in limited angular range with the control satellite antenna, on this worm gear, also directly be provided with simultaneously big Extendible flake in addition, switch and the limited range of making zero of conflicting during rotation embodies its position, plus or minus angle with respect to mid point, obtains to make zero parameter.A1 is a worm screw among the figure, and A2 is a body.
So, this structure still has many shortcomings, for example, utilize the little Extendible flake left and right limit inductive switch of when worm gear rotates, conflicting, because little Extendible flake is and the integrated stationary structure of worm gear, can't change self-position, so rotational angle range must be bound in the fixing angular range, can't set other angular ranges again; Secondly, be located at the left and right position with two groups of inductive switch branches, cost is higher: the another one problem then is, because of large and small Extendible flake all is arranged on worm gear periphery and stretches out, the difficulty on causing the one-body molded exploitation of plastic mould, under long-time the use, large and small Extendible flake fractures easily, cause the deficiency on the constructional device, cause whole group structure to be replaced, increase many costs relatively.
The purpose of this utility model is a kind of satellite antenna swivel base that improves structure of design, can control satellite antenna easily and rotate in the angular range of setting, and can reduce employed inductive switch.
The technical scheme that realizes the utility model purpose is such: a kind of satellite antenna swivel base that improves structure, comprise body, motor, gear train, worm screw, worm gear, body seat and body, motor external gear group, gear train engages worm one end, worm screw is connected worm gear, the worm gear axle center wears the body seat and is connected with body, it is characterized in that: described body seat is provided with an axis hole, be formed with short slot on the peritreme of seat axis hole, offer more than one inserting hole on the body seat in the seat axis hole outside, be plugged with inserted sheet in the inserting hole; Described worm gear is provided with the bearing hole, is provided with a direction make zero a switch and an angle inductive switch in the bearing hole.
The distance of described more than one inserting hole is rotated positive and negative angular distance by worm gear angle inductive switch and is set, and described short slot is positioned at the point midway place of an above inserting hole.
The described direction switch that makes zero becomes the Internal and external cycle setting respectively with an angle inductive switch in described worm gear.
Be provided with internal thread in the described inserting hole, correspondence is provided with thread segment on the described inserted sheet.
Revolution, transmission external gear group, and engages worm rotation, the worm gear that is connected with worm screw rotates thereupon, and the rotation of control body, rotates to drive dish-shaped disk body.
The utility model improves the satellite antenna swivel base of structure, make zero switch and angle inductive switch of set direction respectively in the worm gear of satellite antenna swivel base, and on the body seat respectively correspondence establish inserted sheet and short slot, when the dish-shaped disk body of satellite antenna rotates, the angle inductive switch rotates to move and can conflict with worm gear and is arranged at left and right inserted sheet, to rotate in the angular range that is controlled at setting; By short slot and direction the make zero conflict or the disengaging of switch, the parameter that obtains to make zero is to differentiate positive negative direction, to increase the accuracy and the convenience of control satellite antenna rotational angle in addition.
The utility model improves the satellite antenna swivel base of structure, in worm gear, establish the bearing seat, and direction make zero switch and angle inductive switch be set respectively, utilize angle inductive switch left and right sides inserted sheet on the conflict body seat when worm gear rotates, being controlled satellite antenna easily rotates in the angle of setting, and this angle inductive switch also is reduced to one group by two groups, has not only improved the rotation accuracy, has also reduced manufacturing cost.
The utility model improves the satellite antenna swivel base of structure, and the inserted sheet on the body seat adopts the plant mode to fix, and the body seat is provided with several inserting holes, by changing the inserting hole that inserted sheet is planted, just can adjust the rotational angle that sets, two kinds of settings with upper angle can be provided at least.
The utility model improves the satellite antenna swivel base of structure, is provided with short slot on the body seat, can make in direction makes zero switching range, presents the position, plus or minus angle of relative what mid point and obtains the parameter that makes zero.
The utility model improves the satellite antenna swivel base of structure, single group angle inductive switch and the direction switch that makes zero directly is set on worm gear, makes when making worm gear, can adopt standard module type normalized production, thereby make product at aspects such as production cost, efficient, accuracy, all can take advantage.
Further specify technology of the present utility model below in conjunction with embodiment and accompanying drawing.
