The first embodiment is as follows:

referring to fig. 1, the present invention provides a technical solution: the utility model provides a 5G radio frequency filter feeds source seat, includes feed disk body 1, feed disk body 1 goes up fixedly connected with lower extreme and runs through feed disk body 1's installation head 2, therefore the installation end on the radio frequency filter is placed in installation head 2, through at the radio frequency filter installation end with install the installation bolt between head 2 for the bolt forms fixed effect to radio frequency filter, a plurality of mounting hole 3 has been seted up to feed disk body 1's surface simultaneously, thereby make this radio frequency filter feed source seat can install on the satellite pot.

The scheme also provides an embodiment II;

referring to fig. 1-4, the second embodiment is a corresponding improvement on the basis of the first embodiment, and further a plurality of arc-shaped extrusion plates 5 are arranged on the inner side surface of the mounting head 2, and the number of the arc-shaped extrusion plates 5 is set according to the actual diameter of the mounting head 2, which is not described herein in detail, so that when the mounting end of the rf filter is placed on the mounting head 2, the surface of the mounting end of the rf filter is extruded by the arc-shaped extrusion plates 5, and thus, the fixing of the rf filter can be completed;

further be provided with frictional layer 6 on one side surface that arc stripper plate 5 is back to installation head 2 inner wall, frictional layer 6 does not do too much repeated description here for current structure, has increased the coefficient of friction between arc stripper plate 5 and the radio frequency filter installation end like this, has further increased the fastness between arc stripper plate 5 and the radio frequency filter, has avoided appearing becoming flexible after the radio frequency filter installation.

Further, the control ring 4 is movably sleeved on the outer side of the mounting head 2, the outer surface of the mounting head 2 is provided with a thread tooth 7, and the inner ring of the control ring 4 is provided with a thread groove 8 in threaded connection with the thread tooth 7, so that when the control ring 4 rotates, the control ring 4 respectively moves upwards or downwards under the transmission of the thread tooth 7 and the thread groove 8.

Further, a plurality of built-in cavities 9 matched with the arc-shaped extrusion plates 5 are arranged in the mounting head 2, one side surfaces of the arc-shaped extrusion plates 5 facing the built-in cavities 9 are fixedly connected with pushing slide rods 10, one ends of the pushing slide rods 10 far away from the arc-shaped extrusion plates 5 penetrate into the built-in cavities 9 and are in sliding connection with the inner wall of the mounting head 2, one ends of the pushing slide rods 10 in the built-in cavities 9 are fixedly connected with limiting plates 11, one side surfaces of the limiting plates 11 facing the pushing slide rods 10 are fixedly connected with spring components 12, in the embodiment, the spring components 12 are elastic components, for example, components made of springs and rubber materials, and the spring components 12 are movably sleeved on the pushing slide rods 10 and are fixedly connected to the inner wall of the built-in cavities 9 far away from the limiting plates 11, so that the spring components 12 have a certain length, and the spring components 12 form a supporting effect on the limiting plates 11, thus, the initial position of the arc-shaped pressing plate 5 is the side close to the inner wall of the mounting head 2.

Furthermore, a control push rod 13 is fixedly connected to a surface of the limiting plate 11 on a side opposite to the push slide rod 10, one end of the control push rod 13, which is far away from the limiting plate 11, penetrates through the outer surface of the mounting head 2 and is slidably connected with the inner wall of the mounting head 2, a control groove 14 is formed on a surface of the control ring 4 on a side facing the control push rod 13, the cross section of the control groove 14 is an inclined surface, and the control push rod 13 is in an initial state of being in contact with the control groove 14, so that when the control ring 4 is displaced downwards, the control groove 14 extrudes the control push rod 13, so that the control push rod 13 gradually slides towards one side in the built-in cavity 9, thereby synchronously pushing the push slide rod 10 to displace, and simultaneously the spring component 12 contracts under the force, so that the arc-shaped extrusion plate 5 extrudes the outer surface of the mounting head of the radio frequency filter, otherwise, only the control ring 4 needs to be displaced upwards when the radio frequency filter needs to be removed, this causes the control groove 14 not to be pressed against the control push rod 13, so that the arc-shaped pressing plate 5 is restored to the original position by the urging of the spring assembly 12.

The one end that is located the installation head 2 with control push rod 13 further sets up to hemispherical in this embodiment, has increased the smooth degree of control push rod 13 with 14 contact surfaces of control tank through this kind of mode, has further reduced the frictional force that produces when control push rod 13 slides along 14 inclined planes of control tank, has avoided control push rod 13 to appear the dead condition of mechanical card, stability and smoothness when further having improved promotion arc stripper plate 5.

Further, two connecting sliding grooves 15 are formed in the inner walls of the two vertical opposite sides of the built-in cavity 9 in the mounting head 2 respectively, a connecting pulley 16 connected with the connecting sliding grooves 15 in a sliding mode is arranged on the surface, facing the connecting sliding grooves 15, of the limiting plate 11, and the connecting pulley 16 supports the limiting plate 11 in this mode, so that friction force generated when the limiting plate 11 slides in the built-in cavity 9 is reduced.

The working principle is as follows: when the 5G radio frequency filter feed source seat is used, the control ring 4 is rotated, so that the control ring 4 is respectively displaced upwards or downwards under the transmission of the thread teeth 7 and the thread grooves 8;

when the control ring 4 moves downwards, the control groove 14 extrudes the control push rod 13, so that the control push rod 13 gradually slides towards one side in the built-in cavity 9, the push slide rod 10 is synchronously pushed to move, and meanwhile, the spring component 12 is stressed to contract, so that the arc-shaped extrusion plate 5 extrudes the outer surface of the mounting head of the radio frequency filter;

when the radio frequency filter needs to be removed, the control ring 4 only needs to be displaced upwards, so that the control slot 14 is not pressed against the control push rod 13, and the arc-shaped pressing plate 5 is restored to the initial position under the pushing of the spring assembly 12.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
