Specific embodiment

This utility model is described in detail with embodiment below in conjunction with the accompanying drawings.

Referred in conjunction with Fig. 4 to Fig. 7, this utility model provides a kind of antenna drive device, antenna drive device master Including：Installing rack 1, the drive screw 2 for being installed on installing rack 1 and can rotating relative to installing rack 1 and regulation knob 4.

Certainly, it is to realize that armstrong's patent adjusts the phase shifter and has a down dip function, being arranged with drive screw 2 can be along drive screw 2 The transmission nut 3 for moving back and forth, phase shifter（Not shown）Pull bar can be passed through（Not shown）Further fix with transmission nut 3 and connect Connect.

In a specific embodiment, adjusting knob 4 includes hollow body 41.41 one end of body sealed by lid 42, Another end opening, also, there is body 41 cross section inwall 420 in a ring, position of the inwall 420 only at the adjacent openings to set It is equipped with some female threads 411 and remaining position is smooth.Correspondingly, shelve and be provided with the installation set passed through for 2 one end of drive screw Cylinder 11, the outer wall of installation sleeve 11 are provided with the external screw thread 111 being engaged with the female thread 411 for adjusting knob 4.

Adjust cooperation of the knob 4 by female thread 411 with external screw thread 111 to be movably connected in installation sleeve 11, especially Which is that other positions are set to shiny surface on the inwall 420 for adjust knob 4, and enabling to regulation knob 4 swimmingly can install Reciprocatingly slided on the outer wall of sleeve 11 vertically, while, it is also possible to swimmingly circumferentially reciprocal on the outer wall of installation sleeve 11 Slide.

Further, adjust lid 42 in knob 4 and the central authorities of opening side are provided with joggle piece 421, along body 41 Keep at a certain distance away and 411 bottom of female thread between at the top of the axial direction joggle piece 421.Correspondingly, 2 neighbouring peace of drive screw Sleeved 11 one end end face is provided with engaging hole 21.Enable to regulation knob 4 and can pass through joggle piece 421 and engaging hole 21 Cooperation be engaged with drive screw 2.Wherein, because regulation knob 4 axially and can slide axially in installation sleeve 11, And then can realize that adjusting knob 4 can be engaged with drive screw 2 pluggablely.

During use, as shown in fig. 6, be screwed into knob 4 is adjusted in the installation sleeve 11 of installing rack 1, as antenna is vertically put Put, adjusting knob 4 can be sagging under the conditions of self gravitation, and then protection transmission converting interface can be played a part of.Such as Fig. 7 institutes Show, and need manually to adjust the phase shifter when having a down dip, will adjust knob 4 above pushes away, and adjusts joggle piece 421 and transmission spiral shell on knob 4 Engaging hole 21 on bar 2 is engaged, so as to realize adjusting manually the function that the phase shifter has a down dip.

In a specific embodiment, 42 central authorities of lid of regulation knob 4 are axially extending to form guide post 422, the engagement Part 421 is integrally formed at the outer wall of 422 adjacent caps of guide post, 42 one end.The setting of guide post 422 not only facilitates and forms engagement Part 421, and guide effect can be played when the joggle piece 421 for adjusting knob 4 to be pushed the engaging hole 21 of drive screw 2. Certainly, be coordinate guide post 422 insertion, 2 corresponding position of drive screw is provided with gathering sill 22.

In above-mentioned embodiment, at least body 41 can be molded into integral structure using plastic cement material with lid 42.Certainly, Body 41, lid 42, guide post 422 and the joggle piece 421 being formed on guide post 422 can also be molded into using plastic cement material Integral structure.

In addition, the female thread 411 for adjusting 4 inwall 420 of knob generally could be arranged to below three circles such as a circle or two circles, this Sample can not affect to adjust knob 4 is firm be connected to installing rack 1 on the premise of, be to adjust knob 4 to provide bigger axial direction shifting Dynamic space.Female thread 411 on 4 inwall 420 of regulation knob can be continuous thread or interrupted screw-thread.

In a specific embodiment, leaking hole 44 can also be set on lid 42, be adjusted with facilitating to discharge to penetrate into Moisture inside knob 4.

Further, 41 outer wall of body is provided with multiple tracks groove 43, the extension of each groove 43 along circumferential direction uniform intervals Direction is consistent with the axial direction of body 41.The setting of groove 43 can increase when user twists regulation knob 4 and adjust knob 4 Between frictional force, it is easier to turn regulation knob 4, and then the convenient regulation had a down dip by the phase shifter.

In above-mentioned embodiment, 41 outward appearance of body for adjusting knob 4 can be with cylindrical, or can also be square-shaped, As long as inwall 420 annularly can be rotatably assorted with installation sleeve 11 in body 41.

In above-mentioned embodiment, joggle piece 421 is hexagonal plum blossom pillar, and engaging hole 21 is interior hexagonal plum blossom hole.Certainly, engage Part 421 and engaging hole 21 can also be other mutually engageable structures, and such as, joggle piece 421 can also be square cylinder, nibble It is accordingly square opening to close hole 21.

This utility model also provides a kind of regulation knob 4 as described in above-mentioned any embodiment, is not repeated herein to go to live in the household of one's in-laws on getting married State.

Antenna drive device of the present utility model and its regulation knob 4, are not changing original installing rack 1 and drive screw 2 On the basis of structure, by the female thread 411 and joggle piece 421 that adjust in knob 4 are arranged at 42 the same side of lid, female thread 411 only at 420 adjacent openings of inwall in body 41, and joggle piece 421 is located at 42 central authorities of lid, and the axial direction side in body 41 Upwards so that the mode kept at a certain distance away and 411 bottom of female thread between at the top of joggle piece 421 so that adjust knob 4 not only Installing rack 1 can be movably connected on to protect to being driven converting interface, can be engaged with drive screw 2 with plug-in The regulation that the phase shifter has a down dip is realized, it is knob needs to solve antenna for base station workmen and adjust that the phase shifter has a down dip in armstrong's patent The problem of two-sided switching, can improve efficiency of construction, save operating expenses.

Embodiment of the present utility model is these are only, the scope of the claims of the present utility model, every profit is not thereby limited The equivalent structure that is made with this utility model description and accompanying drawing content or equivalent flow conversion, or directly or indirectly it is used in which The technical field of his correlation, is included in scope of patent protection of the present utility model in the same manner.
