Description

Technical Field

[0001] The invention belongs to the technical field of combiners, and in particular relates to a multi-frequency combiner. Background Art

[0002] In wireless mobile phone communication systems, the main function of a combiner is to combine input multi-band signals and output them to the same indoor distribution system.

[0003] In engineering applications, it is necessary to output 800MHz C network, 900MHz G network or other different frequencies at the same time. By using a combiner, an indoor distribution system can work in the CDMA frequency band, GSM frequency band or other frequency bands at the same time.

[0004] For example, in a radio antenna system, the input and output signals of several different frequency bands (such as 145MHZ and 435MHZ) are combined through a combiner and then connected to the radio station with a feeder line. This not only saves a feeder line, but also avoids the trouble of switching different antennas.

[0005] When the existing multi-frequency combiner is in use, dust will accumulate in the socket of the port as it is used continuously. Since the socket is narrow, the dust inside cannot be cleaned out during cleaning, which affects the use in the long run.

[0006] Therefore, it is necessary to invent a multi-frequency combiner to solve the above problems. Summary of the invention

[0010] Furthermore, the first drive block and the second drive block are specifically arc-shaped plate-like components with an arc surface on the side close to the round rod, and the connecting plate is an arc-shaped plate-like component. The connecting plate, the first drive block, and the second drive block all protrude from the outside of the joint on the side away from the ring plate, and the protruding heights of the connecting plate, the first drive block, and the second drive block on the side away from the ring plate increase successively.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a multi-frequency combiner, such as Figures 1 to 6As shown, it includes a combiner 1, on which are provided a plurality of connectors 2. The combiner 1 is a multi-frequency combiner. The connectors 2 are the same as the ports on the combiner in the prior art. A semicircular plate 3 is symmetrically provided inside the connector 2. The semicircular plate 3 is made of the same material as the socket in the combiner port in the prior art. One end of the semicircular plate 3 abuts against the inner wall of the connector 2. A rectangular shell 4 is symmetrically fixedly installed on the inner wall of the connector 2. A slide groove is provided on the outer side of the semicircular plate 3. A slider 5 is slidably installed in the slide groove. The side of the slider 5 close to the combiner 1 is fixedly connected to the inner wall of the slide groove through a first spring 6. A connecting rod 8 is provided on the side of the slider 5 close to the rectangular shell 4. One end of the connecting rod 8 extends to the inside of the rectangular shell 4 and is fixedly connected to a pressure block 7. A driving component for driving the pressure block 7 to move along the rectangular shell 4 is provided on one side of the pressure block 7. A top block 10 cooperating with the semicircular plate 3 is symmetrically fixedly installed on the inner wall of the connector 2 close to the combiner 1. A slope 11 is provided on the side of the top block 10 close to the semicircular plate 3.

[0028] When in use, the plug of the data line is inserted into the connector 2, and the plug of the data line extends to form a connection between the two semicircular plates 3. When maintenance is required, the plug is pulled out, and then the driving component drives the pressing block 7 to move with the connecting rod 8, the slider 5, and the semicircular plate 3, so that a pair of semicircular plates 3 move away from each other. As the semicircular plate 3 moves, the end thereof that contacts the inner wall of the connector 2 moves along the inclined surface 11, thereby being squeezed. As the semicircular plate 3 moves along the inclined surface 11, the semicircular plate 3 moves away from the combiner 1, so that the first spring 6 is compressed by the matching slider 5 to deform and generate a force, so that the end of the semicircular plate 3 that contacts the inner wall of the connector 2 is separated from the connector 2, and then the driving component drives the pressing block 7 to move in the reverse direction quickly, so that the pressing block 7 collides with the inner wall of the rectangular shell 4 to generate vibration, and the vibration is transmitted to the semicircular plate 3 through the connecting rod 8 and the slider 5 to vibrate, and then the driving component continues to drive the pressing block 7 to move and drives the pressing block 7 to move in the reverse direction quickly, thereby realizing the continuous vibration of the semicircular plate 3, so that the material attached to the inner wall of the semicircular plate 3 can be The dust is shaken loose and falls off, and then the driving component drives the pressing block 7 to continue to move, so that the pair of semicircular plates 3 continue to separate, and finally the pair of semicircular plates 3 are in a separated state. Then the staff can blow air into the inside of the joint 2, so as to blow away the dust in the semicircular plates 3 and the joint 2, and realize the cleaning of the semicircular plates 3 and the joint 2. By separating the pair of semicircular plates 3, the airflow can clean the dust mixed between the two semicircular plates 3, and realize the cleaning of the dust in the dead corner between the two semicircular plates 3, and cooperate with the semicircular plates 3 before blowing. The vibration can loosen and shake off the dust attached to the inner wall of the semicircular plate 3, so that the dust can be separated from the semicircular plate 3 more easily, improving the cleaning effect. When resetting is required, the driving component drives the pressing block 7 to reset, and vice versa. During the resetting process of the semicircular plate 3, the compressed first spring 6 continuously releases the force to bring the semicircular plate 3 closer to the combiner 1, and finally the semicircular plate 3 contacts the inner wall of the joint 2, so that the two semicircular plates 3 and the joint 2 form a port on the combiner in the prior art, which can be used normally.

[0029] like Figures 2 to 6 As shown, the driving assembly includes a second spring 9 fixedly connected to the side of the pressure block 7 away from the semicircular plate 3, a pull rod 12 is fixedly installed on the side of the pressure block 7 away from the semicircular plate 3, one end of the pull rod 12 away from the pressure block 7 passes through the joint 2 and extends to the outside thereof and is fixedly connected to a round rod 13, an annular groove is provided on the outside of the joint 2, a ring plate 14 is rotatably installed in the annular groove, a plurality of first driving blocks 15 and second driving blocks 16 that cooperate with the round rod 13 are fixedly installed on the outer side of the ring plate 14, and adjacent first driving blocks 15 and second driving blocks 16 and first driving blocks 15 are connected by connecting plates 22.

[0030] The ring plate 14 is rotated forward to rotate with the first driving block 15, the connecting plate 22, and the second driving block 16. The first driving block 15 contacts the round rod 13 and presses against the round rod 13 to move with the pull rod 12 and the pressure block 7. At the same time, the pressure block 7 compresses the second spring 9 to deform it and generate a force. When the first driving block 15 is separated from the round rod 13, the compressed second spring 9 releases the force to move the pressure block 7 in the opposite direction quickly, so that the pull rod 12 and the round rod 13 move accordingly. The round rod 13 collides with the connecting plate 22 to generate vibration, and the vibration is transmitted to the pull rod 12, the pressure block 7, and the connecting plate 22. The rod 8, the slider 5, and the semicircular plate 3 cause the semicircular plate 3 to vibrate. Subsequently, as the multiple first driving blocks 15 are separated from the round rod 13, the semicircular plate 3 continues to vibrate. When the second driving block 16 is in contact with the round rod 13, the pressure block 7 is driven to move in the same way, so that the pair of semicircular plates 3 move away from each other, and then the rotation of the ring plate 14 is stopped, so that the pair of semicircular plates 3 maintain a separated state, and the ring plate 14 is continuously rotated to separate the second driving block 16 from the round rod 13. Then the second spring 9 releases its force to reset the pressure block 7, thereby realizing the reset of the semicircular plate 3.

[0031] like Figure 2 As shown, the first drive block 15 and the second drive block 16 are specifically arc-shaped plate-like components with an arc surface on the side close to the round rod 13, and the connecting plate 22 is an arc-shaped plate-like component. The connecting plate 22, the first drive block 15, and the second drive block 16 protrude from the outside of the joint 2 on the side away from the ring plate 14, and the protruding heights of the connecting plate 22, the first drive block 15, and the second drive block 16 on the side away from the ring plate 14 increase successively.

[0032] When the arc surfaces of the first driving block 15 and the second driving block 16 come into contact with the round rod 13, they can both push against the round rod 13 to make it move with the pull rod 12 and the pressure block 7, thereby realizing the mutual separation of a pair of semicircular plates 3. When the second driving block 16 comes into contact with the round rod 13 on the side away from the ring plate 14, the round rod 13 moves to the farthest distance, that is, the two semicircular plates 3 are separated to the maximum position.

[0033] like Figure 4 and Figure 6 As shown, a side plate 17 is symmetrically fixedly installed at one end of the connecting rod 8 away from the pressure block 7, a rotating shaft 18 is rotatably installed between the two side plates 17, both ends of the rotating shaft 18 extend to the outside of the side plate 17 and are sleeved with torsion springs 19, both ends of the torsion spring 19 are respectively fixedly connected to the rotating shaft 18 and the side plate 17, a push rod 20 is fixedly installed between the two side plates 17, the slider 5 is fixedly sleeved outside the rotating shaft 18, the push rod 20 contacts the side of the slider 5 close to the combiner 1, a stopper 21 is fixedly installed on the side of the inclined surface 11 away from the semicircular plate 3, and the torsion force of the torsion spring 19 is greater than the elastic force of the first spring 6.

[0034] The pressing block 7 moves with the connecting rod 8, the side plate 17, the rotating shaft 18, the slider 5, and the semicircular plate 3. When the semicircular plate 3 moves along the inclined surface 11, the torsion spring 19 maintains the rotating shaft 18, the slider 5, and the semicircular plate 3 without deflection. As the semicircular plate 3 moves, the end thereof that contacts the inclined surface 11 contacts the stopper 21, thereby deflecting, and the slider 5 and the rotating shaft 18 rotate accordingly. At this time, the torsion spring 19 is forced to twist, and finally the semicircular plate 3 is in an inclined state, so that the blown air flow can contact the inner side wall of the semicircular plate 3 to a greater extent, thereby improving the cleaning effect on the inner side of the semicircular plate 3. When the semicircular plate 3 is reset, the torsion spring 19 releases the force to rotate and reset the rotating shaft 18, the slider 5, and the semicircular plate 3, and the push rod 20 contacts the slider 5, so as to ensure that the semicircular plate 3 remains in a state of vertical contact with the inner wall of the interface 2.

[0035] like Figure 6 As shown, when the semicircular plate 3 slides along the inclined surface 11, the torsion force of the torsion spring 19 is sufficient to keep the rotating shaft 18, the slider 5 and the semicircular plate 3 from tilting.

[0036] like Figure 2 As shown, the two semicircular plates 3 can form a complete circular jack for the data line plug to be connected, so as to ensure the normal use of the combiner.

[0037] like Figure 4 As shown, the top block 10 is made of stainless steel, and the surface of the inclined surface 11 is smooth, so that the inclined surface 11 on the top block 10 is not easy to rust, thereby avoiding huge wear on the semicircular plate 3 when it moves, and protecting the semicircular plate 3.

[0038] like Figure 2 As shown, a rubber sheet is provided on the surface of the second driving block 16. When the round rod 13 contacts the rubber sheet and stops the ring plate 14, the ring plate 14 is not easily deflected due to accidental contact, so that the round rod 13 can maintain its position.

[0039] Working principle: When in use, insert the plug of the data line into the connector 2, and the plug of the data line extends to form a connection between the two semicircular plates 3. When maintenance is needed, pull out the plug, rotate the ring plate 14 in the forward direction to make it rotate with the first drive block 15, the connecting plate 22, and the second drive block 16. After the first drive block 15 contacts the round rod 13, the arc surface presses against the round rod 13 to make it move with the pull rod 12 and the pressure block 7. At the same time, the pressure block 7 compresses the second spring 9 to deform it to generate a force, and the pressure block 7 moves with the connecting rod 8, the side plate 17, the rotating shaft 18, the slider 5, and the semicircular plate 3. When the semicircular plate 3 moves along the inclined surface 11, the torsion spring 19 maintains the rotating shaft 18, the slider 5, and the semicircular plate 3. The plate 3 does not deflect. As the semicircular plate 3 moves along the inclined surface 11, it moves against the semicircular plate 3 away from the combiner 1, so that the cooperating slider 5 compresses the first spring 6 to deform it and generate a force, so that the end of the semicircular plate 3 that contacts the inner wall of the joint 2 is separated from the joint 2, which can facilitate the airflow to carry dust away from the semicircular plate 3. Then the first driving block 15 is separated from the round rod 13, and the compressed second spring 9 releases the force to carry the pressure block 7 to move in the opposite direction quickly, so that the pull rod 12 and the round rod 13 move accordingly, and the round rod 13 collides with the connecting plate 22 to generate vibration, which is transmitted to the pull rod 12, the pressure block 7, the connecting rod 8, the side plate 17, the rotating shaft 18, the slider 5, and the semicircular plate. 3, causing the semicircular plate 3 to vibrate, and subsequently, as the plurality of first driving blocks 15 are separated from the round rod 13 by the abutment, the semicircular plate 3 is continuously vibrated, so that the dust attached to the inner wall of the semicircular plate 3 can be shaken loose and shaken off, and then, after the second driving block 16 abuts against the round rod 13, the arc surface moves against the round rod 13, so that the pair of semicircular plates 3 continue to move away from each other, and as the semicircular plate 3 moves, the end thereof abutting against the inclined surface 11 abuts against the stopper 21, thereby deflecting, and the slider 5 and the rotating shaft 18 rotate accordingly, and at this time, the torsion spring 19 is forcibly twisted, and finally the semicircular plate 3 is in an inclined state, and then the rotation of the ring plate 14 is stopped, so that the pair of semicircular plates 3 maintain a separated state. The staff can then blow air into the joint 2, thereby blowing away the dust in the semicircular plate 3 and the joint 2, and cleaning the semicircular plate 3 and the joint 2. By separating a pair of semicircular plates 3, the airflow can clean the dust mixed between the two semicircular plates 3, and the dust in the dead corner between the two semicircular plates 3 can be cleaned. Before blowing, the semicircular plate 3 is vibrated to loosen and fall the dust attached to the inner wall of the semicircular plate 3, so that the dust can be separated from the semicircular plate 3 more easily, thereby improving the cleaning effect. By tilting the semicircular plate 3, the blown airflow can contact the inner wall of the semicircular plate 3 to a greater extent, thereby improving the cleaning effect on the inner side of the semicircular plate 3.After cleaning, the ring plate 14 is rotated continuously to separate the second driving block 16 from the round rod 13. Then, the second spring 9 releases its force to reset the pressure block 7. The pressure block 7 moves with the connecting rod 8, the side plate 17, the rotating shaft 18, the slider 5, and the semicircular plate 3. The torsion spring 19 releases its force to rotate and reset the rotating shaft 18, the slider 5, and the semicircular plate 3. The compressed first spring 6 continuously releases its force to move the semicircular plate 3 closer to the combiner 1. Finally, the semicircular plate 3 contacts the inner wall of the joint 2, so that the two semicircular plates 3 and the joint 2 form a port on the combiner in the prior art and can be used normally. ;

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
