Specific embodiment

For the ease of the understanding of those skilled in the art, the utility model is made below with reference to embodiment and attached drawing further Explanation, the content that embodiment refers to not is restriction to the utility model.

In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right", The orientation or positional relationship of the instructions such as "vertical", "horizontal", "top", "bottom", "inner", "outside" be orientation based on the figure or Positional relationship is merely for convenience of describing the present invention and simplifying the description, rather than the device or member of indication or suggestion meaning Part must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise specified and limited, term " installation ", " phase Even ", " connection " shall be understood in a broad sense, for example, it may be mechanical connection or electrical connection, the company being also possible to inside two elements It is logical, it can be directly connected, can also indirectly connected through an intermediary, for the ordinary skill in the art, it can To understand the concrete meaning of the term as the case may be.

As shown in Figs. 1-5, a kind of antenna clamping device, including two clamp systems, clamp system include pedestal 1, driving Component and two grip the clamp arm 2 of symmetrical dipole B, two clamp arms 2 be oppositely arranged on pedestal 1 and respectively with pedestal 1 is slidably connected, and driving assembly is for driving two clamp arms 2 to lean on two clamp arms 2 mutually as counter motion on pedestal 1 Hold together or is separated from each other.

Antenna clamping device in above embodiment during installation, needs for two clamp systems to be separately mounted to symmetrically The lower section at the both ends oscillator B guarantees that the both ends of symmetrical dipole B can be respectively fallen in two clamp arms of corresponding clamp system, Specific use process is as follows for the antenna clamping device:

When the flagpole antenna on communication truck needs to be reduced to lowest part, by two on driving assembly driving clamp system Clamp arm 2 separates, and flagpole antenna is fallen to lowest part using elevating lever, at this point, one end of symmetrical dipole B falls into one of them In two clamp arms 2 of clamp system, the other end of symmetrical dipole B is fallen into two clamp arms 2 of another clamp system, Driving assembly is finally recycled mutually to draw close two clamp arms 2 on clamp system until the end of symmetrical dipole B is clamped It fixes；

When the flagpole antenna on communication truck needs to be lifted to eminence in use, by two on driving assembly driving clamp system A clamp arm 2 separates so that symmetrical dipole B is released, and flagpole antenna is being lifted to eminence using elevating lever.

Further, the opposite inside of two clamp arms 2 symmetrically offers multiple groups groove 2a, when two clamp arms 2 are driving When sticking together under the action of dynamic component, every group of groove 2a is respectively formed one for gripping the end symmetrical dipole B The quantity of square hole, each 2 upper groove 2a of clamp arm is identical as the quantity of symmetrical dipole B on flagpole antenna, herein, specifically, The quantity of symmetrical dipole B is two, therefore the groove 2a on each clamp arm 2 is also two.

In actual use, the end of symmetrical dipole B is clamped in folder to the antenna clamping device of above embodiment In the groove 2a of tight arm 2, symmetrical dipole B is damaged because colliding, rubbing between symmetrical dipole B and clamp arm 2 in order to prevent, Rubber layer can be set on the inner wall of groove 2a, and rubber has certain soft elasticity, can play protection and buffer function well.

In the prior art, the mode being slidably connected between pedestal 1 and clamp arm 2 is more, can make to open up on pedestal 1 and lead To slot, corresponding directive wheel or guide pad are set on clamp arm 2, alternatively, two guide rails being oppositely arranged 3 are installed on pedestal 1, There are two the sliding block 4 to match respectively with two guide rails 3, clamp arm 2 passes through on sliding block 4 and pedestal 1 for the bottom connection of clamp arm 2 Two guide rails 3 be slidably connected, in addition there are also more implementations, do not enumerate herein, and the bottom in present embodiment Connection type between seat 1 and clamp arm 2 is achieved using the latter, as shown in figures 1 and 3.

Further, driving assembly includes motor 5 and retarder 6, and motor 5 is connect with retarder 6, the output of retarder 6 Axis is connect with a screw rod 7, and screw rod 7 runs through the bottom of two clamp arms 2 and is threadedly coupled therewith, and the rotation of screw rod 7 can drive two A clamp arm 2 moves, in order to make the direction of motion of two clamp arms 2 on the contrary, the spiral shell being connected on screw rod 7 with two clamp arms 2 The rotation direction of line should be opposite.When motor 5 forward or reverse when, the output shaft of retarder 6 drives screw rod 7 together clockwise or the inverse time Needle rotation, thus promote two clamp arms 2 on guides 3 reverse slide until both mutually draw close or separated.

Preferably, as shown in figure 3, the bottom of clamp arm 2 can also connect a link block 8, offered on the link block 8 with The tapped through hole that screw rod 7 matches, two clamp arms 2 are threadedly coupled with screw rod 7 by respective link block 8 respectively, are needed herein It should be noted that the thread rotary orientation in the tapped through hole of two corresponding link blocks 8 of clamp arm 2 is opposite.

More preferably, one end of two guide rails 3 is also connected with one piece of fixed plate 9, and the output shaft of retarder 6 is from fixed plate 9 Outside be through to inside, screw rod 7 is located between two guide rails 3, the link block 8 of 2 bottom of clamp arm be located at two sliding blocks 4 it Between.

Above-described embodiment is the preferable implementation of the utility model, and in addition to this, the utility model can be with other sides Formula realizes that any obvious replacement is in the protection model of the utility model under the premise of not departing from the technical program design Within enclosing.

In order to allow those of ordinary skill in the art more easily understand the improvement of the utility model compared with the existing technology it Place, some attached drawings of the utility model and description have been simplified, and for the sake of clarity, present specification is omitted one A little other elements, the element that those of ordinary skill in the art should be aware that these are omitted also may make up the interior of the utility model Hold.
