Description

Technical Field

[0001] The utility model relates to the technical field of feeder cable storage, in particular to a storage structure for antenna feeder cables. Background Technique

[0002] In 4G and 5G technologies, the feeder cable, as a transmission line connecting the antenna and the transmitting or receiving device, plays a crucial role. The 4G network relies on the feeder cable to connect the base station radio frequency unit and the antenna. 5G has higher requirements for the performance of the feeder cable due to its higher frequency band and advanced antenna technology, such as low loss, good shielding, support for high bandwidth and fast transmission speed, etc. Its performance directly affects network coverage, signal quality and transmission speed.

[0003] Most of the existing storage structures for antenna feeder cables directly place the wire coil inside the storage box. However, during actual use, since the storage box is placed in a transportation vehicle, bumps will cause the rotating shaft inside it to rotate, resulting in the loosening of the wires inside the coil, which is not convenient for use. At the same time, the wire end leaking out of the storage box during use cannot be fixed, which may cause it to move towards the inside of the storage box. When the wire end drops into the inside of the storage box, the user needs to open the storage box to lead the wire. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a storage structure for antenna feeder cables, which has the advantages of wire coil fixation and wire end fixation, and solves the problems raised in the above background technique.

[0005] The utility model provides the following technical solutions:

[0006] A storage structure for antenna feeder cables includes a box body. A closing door is rotatably connected to the inner wall of the box body. A wire clamping assembly is arranged on the outer wall of the box body. A rotating shaft and a wire guiding roller are respectively rotatably connected to the inner wall of the box body. A gear is fixedly installed on one side of the rotating shaft close to the inner wall of the box body. A handle is fixedly installed on the side of the gear away from the rotating shaft. A threaded rod is rotatably connected to the inner wall of the box body. A rotating cap is fixedly installed on the top of the threaded rod. A guide rail is fixedly installed on the inner wall of the box body. A fixed tooth block is slidably connected to the inner wall of the box body.

[0007] As a preferred technical solution of the utility model, the wire clamping assembly includes a fixed block. An extended top block is fixedly installed on the top of the fixed block. A pulling column is slidably connected to the inner wall of the fixed block. A pull rod and a clamping piece are respectively fixedly installed at both ends of the pulling column. A limiting piece is fixedly installed on the outer wall of the pulling column. A locking block is slidably connected to the inner wall of the extended top block. A lifting column is fixedly installed on the top of the locking block. A fixed rail is fixedly installed on the inner wall of the extended top block. A first spring is arranged on the inner wall of the extended top block. A second spring is arranged on the inner wall of the fixed block.

[0008] As a preferred technical solution of the present utility model, a rectangular groove is provided at the top of the limiting piece, and the size of the rectangular groove is adapted to the size of the locking block. A bevel surface is provided at the bottom of the locking block, and the bevel surface faces the limiting piece.

[0009] As a preferred technical solution of the present utility model, the fixed rail penetrates through the locking block, and the number of the fixed rails is two. The two fixed rails are symmetrically distributed on both sides of the lifting column.

[0010] As a preferred technical solution of the present utility model, the fixed tooth block is located above the gear, and the shape of the fixed tooth block is adapted to the teeth of the gear.

[0011] As a preferred technical solution of the present utility model, three extension blocks are provided on the outer wall of the fixed tooth block, and the threaded rod and the guide rail penetrate through the three extension blocks. The number of the guide rails is two, and the threaded rod is threadedly connected to the fixed tooth block through the extension blocks on the outer wall of the fixed tooth block.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. For the storage structure of the antenna feeder, by rotating the rotating cap, the rotating cap drives the threaded rod to rotate. The threaded rod drives the fixed tooth block downward through the thread provided on the outer wall, so that the fixed tooth block moves downward on the outer wall of the guide rail. When the fixed tooth block moves to the lowest position, the fixed tooth block is clamped with the teeth of the gear, making the gear unable to rotate, and further making the rotating shaft unable to rotate. The wire reel outside it cannot rotate, so that the internal wire reel cannot rotate during its transportation, and thus the wire reel will not scatter.

[0014] 2. For the storage structure of the antenna feeder, by placing the feeder inside the fixed block and pulling up the lifting column, the lifting column drives the locking block to move upward, and then the first spring contracts, so that the locking block disengages from the rectangular groove at the top of the limiting piece. At this time, the second spring rebounds and pushes the clamping piece back, so that the two clamping pieces clamp the outer wall of the feeder inside the fixed block, and thus the exposed wire head cannot move and will not enter the inside of the box body.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 - Figure 5 , a storage structure for an antenna feeder, including a box body 1, a closing door 2 is rotatably connected to the inner wall of the box body 1, a wire clamping assembly 3 is arranged on the outer wall of the box body 1, a rotating shaft 4 and a wire guiding roller 5 are respectively rotatably connected to the inner wall of the box body 1, a gear 6 is fixedly installed on the side of the rotating shaft 4 close to the inner wall of the box body 1, a handle 7 is fixedly installed on the side of the gear 6 away from the rotating shaft 4, a threaded rod 9 is rotatably connected to the inner wall of the box body 1, a rotating cap 8 is fixedly installed on the top of the threaded rod 9, a guide rail 11 is fixedly installed on the inner wall of the box body 1, a fixed tooth block 10 is slidably connected to the inner wall of the box body 1. In the above structure, a circular groove is provided on the inner wall of the box body 1 close to the wire clamping assembly 3, and the wire guiding roller 5 is located above the circular groove. The feeder can be transmitted to the inside of the wire clamping assembly 3 through the circular groove on the inner wall of the box body 1, and the feeder is guided by the wire guiding roller 5 so that the feeder does not contact the inner wall of the box body 1.

[0024] In a preferred embodiment, the wire clamping assembly 3 includes a fixed block 301. An extension top block 302 is fixedly installed at the top of the fixed block 301. A pulling column 303 is slidably connected to the inner wall of the fixed block 301. A pull rod 305 and a clamping piece 306 are respectively fixedly installed at both ends of the pulling column 303. A limiting piece 304 is fixedly installed on the outer wall of the pulling column 303. A locking block 307 is slidably connected to the inner wall of the extension top block 302. A lifting column 308 is fixedly installed at the top of the locking block 307. A fixed rail 310 is fixedly installed on the inner wall of the extension top block 302. A first spring 309 is arranged on the inner wall of the extension top block 302. A second spring 311 is arranged on the inner wall of the fixed block 301. In the above structure, the feeder line is clamped and fixed by the two clamping pieces 306, so that the feeder line will not move into the interior of the box body 1. By pulling the two pull rods 305, the two pull rods 305 drive the two clamping pieces 306 to move. The two clamping pieces 306 drive the limiting piece 304 and the clamping piece 306 to move, so that the clamping of the feeder line is cancelled. At this time, the feeder line can be pulled. When the limiting piece 304 moves to the bottom of the locking block 307, the locking block 307 clamps and fixes the limiting piece 304, so that the clamping piece 306 is fixed.

[0025] In a preferred embodiment, a rectangular groove is provided at the top of the limiting piece 304, and the size of the rectangular groove is adapted to the size of the locking block 307. A slope is provided at the bottom of the locking block 307, and the slope is arranged facing the limiting piece 304. In the above structure, when the limiting piece 304 moves to the outer wall of the locking block 307, it abuts against the bottom of the slope at the bottom of the locking block 307. At this time, continue to move the limiting piece 304, so that the limiting piece 304 moves the locking block 307 upward through the slope at the bottom of the locking block 307, and thus the first spring 309 contracts. When the rectangular groove at the top of the limiting piece 304 moves to the bottom of the locking block 307, the first spring 309 ejects the locking block 307, so that the locking block 307 fixes the limiting piece 304.

[0026] In a preferred embodiment, the locking block 307 is penetrated by the fixed rails 310, and the number of the fixed rails 310 is two. The two fixed rails 310 are symmetrically distributed on both sides of the lifting column 308. In the above structure, the locking block 307 is limited by the two fixed rails 310, so that the locking block 307 can only move on the outer walls of the two fixed rails 310.

[0027] In a preferred embodiment, the fixed tooth block 10 is located above the gear 6, and the shape of the fixed tooth block 10 is adapted to the teeth of the gear 6. In the above structure, the gear 6 is prevented from rotating by the engagement of the fixed tooth block 10 with the teeth of the gear 6, so that the rotating shaft 4 cannot rotate.

[0028] In a preferred embodiment, the outer wall of the fixed tooth block 10 is provided with three extension blocks, and the threaded rod 9 and the guide rail 11 penetrate through the three extension blocks. The number of the guide rails 11 is two, and the threaded rod 9 is threadedly connected to the fixed tooth block 10 through the extension blocks on the outer wall of the fixed tooth block 10. In the above structure, the movement track of the fixed tooth block 10 is limited by the two guide rails 11, so that the fixed tooth block 10 will not shift during movement. The threaded rod 9 is threadedly connected to the fixed tooth block 10. By rotating the threaded rod 9, the outer wall thread of the threaded rod 9 rotates, thereby driving the fixed tooth block 10 to move up and down.

[0029] Working principle: When using this device, open the closing door 2, put the wire reel on the outer wall of the rotating shaft 4, pick up one end of the feeder line and pass it under the wire guide roller 5 to reach the slot on the outer wall of the box body 1, and penetrate it into the fixed block 301. At this time, the clip 306 clamps and fixes the feeder line, so that the feeder line will not move into the interior of the box body 1. By rotating the handle 7, the handle 7 drives the gear 6 to rotate, and the gear 6 drives the rotating shaft 4 to rotate to tighten the wire reel. At this time, rotate the rotating cap 8, and the rotating cap 8 drives the threaded rod 9 to rotate. The threaded rod 9 drives the fixed tooth block 10 to move downward through the thread on the outer wall, so that the fixed tooth block 10 is engaged with the teeth on the outer wall of the gear 6, and the gear 6 is engaged, so that the gear 6 cannot move. When it is necessary to pull out the feeder line, rotate the rotating cap 8 to make the threaded rod 9 rotate. The threaded rod 9 drives the fixed tooth block 10 to move upward, so that the fixed tooth block 10 is disengaged from the gear 6. At this time, the rotating shaft 4 can rotate. By pulling the two pull rods 305, the two pull rods 305 drive the two clips 306 to move. The two clips 306 drive the limit piece 304 and the clip 306 to move, so that the clamping of the feeder line is cancelled. At this time, the feeder line can be pulled. When the limit piece 304 moves to the outer wall of the lock block 307, it abuts against the bottom of the inclined surface at the bottom of the lock block 307. At this time, continue to move the limit piece 304, so that the limit piece 304 moves the lock block 307 upward through the inclined surface at the bottom of the lock block 307, thereby causing the first spring 309 to contract. When the rectangular groove at the top of the limit piece 304 moves to the bottom of the lock block 307, the first spring 309 pushes the lock block 307 out, so that the lock block 307 fixes the limit piece 304. At this time, the two clips 306 are separated from the feeder line, and the feeder line can be pulled outwards. When the feeder line is used up, rotate the rotating cap 8, and the rotating cap 8 makes the fixed tooth block 10 and the gear 6 resume the engagement relationship through the threaded rod 9, so that the rotating shaft 4 cannot rotate. Pull up the lifting column 308, so that the lifting column 308 drives the lock block 307 to move upward, so that the lock block 307 is separated from the rectangular groove at the top of the limit piece 304, so that the second spring 311 rebounds and resets the clip 306 to continue clamping the feeder line so that it will not enter the interior of the box body 1.
