Abstract
The utility model discloses a simple pull-string type antenna steering device which is suitable to rotate outdoor television antennas indoors by a pull-string rope to select the best direction of the television programs of the frequency channel received by the antenna. The simple pull-string type antenna steering device is mainly composed of a casing body, a large rotating disk, a central column, an inclined fixed pulley, a middle pulley, a lower pulley, and the pull-string rope. The simple pull-string type antenna steering device has the advantages of simple structure, easy fabrication, convenient operation, good effect, easy installation, and easy maintenance.
Description
The simple and easy guyed antenna steering gear of the utility model is applicable at the indoor commentaries on classics outdoor television antenna that draws, and selects antenna received television program channel optimum orientation.
There are family, the unit of television set a lot of at present, all wish more clearly to receive the TV programme of several channels on same ground.Because of exterior aerial can't change the corresponding adjustment of antenna direction with receiving channels.Select the optimum orientation of antenna, make clear image the best, at present commercially available rotable antenna has electronic, remote control, structure is more complicated all, cost height, easy break-down, poor reliability, the people's Installation and Debugging that are ignorant of for electronic technology have certain difficulty, thereby are difficult for popularizing use.
The purpose of this utility model provides a kind of simple in structure, easy to use, the simple and easy guyed antenna steering gear that cost is low.
Simple and easy guyed antenna steering gear mainly is configured with: shell body, shell body are two to involute for half, traffic cycle is installed in the middle of the shell body top, has newel traffic cycle center of rotation post along with rotation in the middle of the traffic cycle, the antenna casing body upper side left-right symmetric that is used to install user-selected usefulness on the newel respectively is equipped with a tilting pulley.Tilting pulley is supported by tilting pulley bearing frame, be contained on the tilting pulley spindle, adopt tilting pulley bearing frame screw on shell body, tilting pulley below is equipped with each one of middle pulley, be contained in that stay cord exit, shell body bottom is equipped with lower sheave on the middle pulley axle, the backguy rope is on traffic cycle.Pass through tilting pulley respectively, middle pulley, pass through lower sheave, feed indoorly, can install necessary transition pulley midway additional according to user's house position floor difference, stay cord draws relay antenna at any time according to receiving the different channel needs near introducing the indoor tv machine.
The backguy rope can be selected more solid nylon rope for use.Length is decided on demand, and for making structural volume as far as possible little, and the distance between tilting the wheel is as far as possible little, and tilting race installation direction is facing to the tangential direction of big rotation race.
Simple in structure, the manufacturing, easy to use of simple and easy guyed antenna steering gear, make steering force without any need for the energy and install, maintenance all is easy to, and is good through trial effect, antenna on the higher roof downstairs also can be adjusted antenna direction in the room by the middle several pulleys that are provided with.As long as on the steering gear newel, load onto the antenna of user-selected usefulness, the shell body bottom is installed in the cramp bar height of putting on the shelf, at rope of the bottom of transducer pulling, stay cord passes through tilting pulley again through lower sheave, middle pulley, arrive big swiveling wheel, big swiveling wheel rotates, because of swiveling wheel and newel are an integral body greatly, newel rotates, the antenna that is contained on the newel just can rotate to a direction, goes to optimum orientation, if another root rope of pulling, then great wheel rotates round about and drives newel and antenna reverse rotation, and both direction turns 360 ° of scopes.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure vertical view.
Among the figure 1, newel, 2, shell body, 3, tilting pulley, 4, tilting pulley bearing frame screw, 5, middle pulley, 6, the middle pulley axle, 7, the backguy rope, 8, lower sheave, 9, tilting pulley bearing frame, 10, tilting pulley spindle, 11, traffic cycle.
Have with reference to the simple and easy guyed antenna steering gear of accompanying drawing primary structure: shell body (2), shell body is for the ease of being assembled into two half involutory being assembled into, shell body (2) internal upper part is equipped with traffic cycle (11), have newel (1) in the middle of the traffic cycle, shell body upper side left-right symmetric respectively is equipped with a tilting pulley (3), tilting pulley is contained on the tilting pulley spindle (10) of tilting pulley bearing frame (9), adopt tilting pulley bearing frame screw (4) to be fixed on the shell body (2), tilting pulley below is equipped with each one of middle pulley (5), in shell body (2) bottom backguy rope (7) exit lower sheave (8) is installed.Backguy rope (7) is on traffic cycle (11), pass through tilting pulley (3) respectively, middle pulley (5) is in the transition pulley inlet chamber by lower sheave (8) and setting as required, spur the stay cord rotable antenna at the indoor different channel of selecting as required, to guarantee the optimum position.
Claims (4)
1, a kind of simple and easy guyed antenna steering gear with pulley, backguy rope, it is characterized in that primary structure has: shell body, shell body internal upper part dress traffic cycle, have newel in the middle of the big trochal disc, shell body internal upper part side left-right symmetric respectively is equipped with a tilting pulley, and tilting pulley is contained on the tilting pulley spindle of tilting pulley bearing frame, adopts tilting pulley bearing frame screw on shell body, tilting pulley below is equipped with middle pulley, in lower housing portion lower sheave is housed; The backguy rope passes through tilting pulley, middle pulley respectively, draws by lower sheave on traffic cycle.
