Description

Technical Field

[0001] This utility model specifically relates to a quick docking mechanism for broadcast transmission tower feeders, belonging to the technical field of docking mechanisms. Background Technology

[0002] Feeder cables play a crucial role in signal transmission in various fields, including cable television systems. They transmit signals received by antennas to the headend system, and the output signals from the headend are also transmitted to individual users' television sets via cables. Therefore, the quality and type of feeder cable are critical factors directly affecting the reception and signal transmission quality of cable television systems.

[0003] Traditional feeder connection primarily involves using a feeder interface. The process requires manual cutting and removing the outer protective sleeve and copper ring at the feeder end to expose the conductor in the center. The processed feeder end is then fitted into a connector, and the outer ring connector is connected to the antenna connector. However, traditional feeder connection requires pre-processing of the feeder end, making the process cumbersome and time-consuming, and it cannot achieve rapid connection. Furthermore, the connection between the connector and the feeder structure relies mainly on the adhesion between the connector and the metal ring, and the force at the adhesion point comes from the friction between the two. Over time, this can lead to loosening during use and handling, and even the risk of disconnection. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional feeder connection requires preprocessing of the feeder port, which is a rather cumbersome process.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a quick docking mechanism for broadcast transmission tower feeders, including a chassis, the central axis of the chassis is set as a hollow structure, and the chassis is set as two sets, one set of chassis with feeders inserted inside, and the other set of chassis with antenna interfaces inserted inside, characterized in that: a protective plate is set on the top of the chassis, a telescopic spring is installed on the bottom of the chassis, a lever is fixedly connected to the top of the telescopic spring, and the inner side of the lever is inserted into the outer side of the protective plate, a flipping frame is rotatably connected to the top of the lever, a flipping frame two is rotatably connected to the end of the flipping frame one away from the lever, and the end of the flipping frame two away from the flipping frame one is rotatably connected to the side of the protective plate.

[0006] Furthermore, the connection points of the flip frame one and the flip frame two are clamped around the feed line of the wiring, and the flip frame one and the flip frame two are arranged in a ring array on the outside of the feed line. The flip frame one and the flip frame two are flush with each other in the original state in the vertical direction.

[0007] Furthermore, a fixing frame is fixedly connected to the top of the protective plate, and a sleeve is fixedly mounted on the top of the fixing frame via a bracket. Nuts are fitted onto the outer edges of the two sets of sleeves, threads are provided on the outer side of the sleeves, and extension grooves are provided on the side of the sleeves. The sleeves are made of hard plastic material, and vertical textures are provided on the inner wall of the sleeves.

[0008] Furthermore, when connected, the nut is inserted into the ends of the two sets of sleeves. After installation, the nut is located in the middle of the two sets of sleeves, and a marking is provided in the middle of the nut.

[0009] Furthermore, a steel wire rope is fixedly connected to the side of the fixed frame, and a telescopic spring is installed at the end of the steel wire rope. A stop is fixedly connected to the bottom of the telescopic spring.

[0012] Furthermore, the limit bracket is made of a soft material, and the bottom end of the stop is in contact with the upper surface of the connecting bracket.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] (1) By setting up a connection mechanism, the feed line and the connector can be connected by the spring extrusion force. Then, the two sets of connector ports are connected by nuts, which ensures that the connection between the feed line end and the connector is quick and convenient. At the same time, the connection of the connector ports is tight and fast, thereby realizing the rapid connection between the feed line and the antenna. It also reduces the pre-processing steps of the feed line end, making the connection process more convenient than the traditional method.

[0015] (2) By setting up a steel wire rope connecting the two sets of fixing frames, the present invention uses the tension of the steel wire rope to ensure that the distance between the fixing frames is maintained within a fixed range, which can ensure that the nut is not easily loosened under external interference, maintain the stability of the connection part, and ensure the tightness of the connection between the feeder and the antenna.

[0016] (3) By setting two sets of identical connection mechanisms, this utility model can achieve mutual compatibility of the interface end mechanisms, enabling the antenna end and feeder end connectors to be converted. Moreover, the overall structure of the connector is simple, and subsequent replacement and maintenance are relatively convenient and quick. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Combined with appendix Figure 1-6 As shown, a quick docking mechanism for a broadcast tower feeder includes a chassis 1. The central axis of the chassis 1 is hollow, and there are two sets of chassis 1. One set of chassis 1 houses the feeder, and the other set houses the antenna interface. A ring array of protective plates 2 is located on the top of the chassis 1. Square slots are provided between the protective plates 2 to provide space for the flipping of the second flipping frame 6. A telescopic spring 3 is installed at the bottom of the chassis 1. The telescopic spring 3 provides power for pushing and lifting the lever 4, and causes the first flipping frame 5 and the second flipping frame 6 to flip. The lever 4 is fixedly connected to the top of the telescopic spring 3. The inner side of plate 4 is fitted onto the outer side of protective plate 2. The top of the lever 4 is rotatably connected to a flipping frame 5. The end of flipping frame 5 away from lever 4 is rotatably connected to a flipping frame 6. The end of flipping frame 6 away from flipping frame 5 is rotatably connected to the side of protective plate 2. The operator first fits the feeder into the inside of a set of chassis 1. Before fitting, the lever 4 is pushed on the top of chassis 1, so that the lever 4 drives flipping frame 5 and flipping frame 6 to flip, so that flipping frame 5 and flipping frame 6 are vertically aligned, providing space for the feeder to fit into the internal channel of chassis 1. The operation process is faster and more convenient, and the position between the feeder and chassis 1 can be quickly determined.

[0026] Then, the feed line port is inserted into the inner wall of the sleeve 8, and the lever 4 is released. The deformation of the telescopic spring 3 moves the lever 4 away from the chassis 1. The lever 4 pushes the connecting end of the flip frame 5 upward, reducing the angle between the flip frame 5 and the flip frame 6. The connecting part of the flip frame 5 and the flip frame 6 will contact the feed line inside the protective plate 2, thereby fixing the position of the feed line and the chassis 1, realizing the quick connection of the feed line and the overall equipment. The same principle can be used to insert the antenna into the inside of another set of sleeves 8. Then, the ports of the two sets of sleeves 8 are attached, and the nut 10 is rotated to the attached position to connect the two sets of sleeves 8. The feed line and the antenna can be quickly connected. Compared with the traditional connection method, the feed line port processing process is eliminated, and the position of the feed line is fixed mainly by the spring force. The connection process is more secure than the traditional friction-based attachment and fixation method.

[0027] As a technical optimization of this utility model, the connection part of the flip frame 1 5 and the flip frame 2 6 is clamped around the feed line. When the angle between the flip frame 1 5 and the flip frame 2 6 increases, the connection part of the flip frame 1 5 and the flip frame 2 6 will move inward toward the central axis of the chassis 1 and contact and clamp the outside of the feed line, making the connection process tighter. The flip frame 1 5 and the flip frame 2 6 are arranged in a ring array on the outside of the feed line. The flip frame 1 5 and the flip frame 2 6 are aligned in the original state in the vertical direction. At this time, the connection part of the flip frame 1 5 and the flip frame 2 6 is on the side of the protective plate 2, providing space for the feed line or antenna to pass through the inside of the protective plate 2 so that it can be connected to the inside of the sleeve 8.

[0028] As a technical optimization of this utility model, a fixing frame 7 is fixedly connected to the top of the protective plate 2. A sleeve 8 is fixedly mounted on the top of the fixing frame 7 through a bracket. Nuts 10 are fitted into the outer edges of the two sets of sleeves 8. Threads are provided on the outer side of the sleeve 8. Extension grooves 9 are provided on the side of the sleeve 8. The extension grooves 9 ensure that the sleeve 8 has extensibility under external force, ensuring that the feeder or antenna can be limited and protected when bent under force. The sleeve 8 is made of hard plastic material, and the inner wall of the sleeve 8 is provided with vertical textures. The vertical textures increase the friction between the feeder and the inner wall of the sleeve 8, preventing the feeder from rotating on the inner wall of the sleeve 8.

[0029] As a technical optimization of this utility model, the nut 10 is fitted into the ends of the two sets of sleeves 8 in the connected state, so that the feed port and antenna port inside the two sets of sleeves 8 fit together for transmission. After installation, the nut 10 is located in the middle of the two sets of sleeves 8, and a mark is set in the middle of the nut 10. The mark setting assists the personnel to move to the interface position of the two sets of sleeves 8 after rotating the nut 10.

[0030] As a technical optimization of this utility model, a steel wire rope 11 is fixedly connected to the side of the fixing frame 7, and a telescopic spring 12 is installed at the end of the steel wire rope 11. A stopper 13 is fixedly connected to the bottom end of the telescopic spring 12. A connecting frame 14 is fixedly provided on the side of another set of fixing frames 7. The steel wire rope 11 is sleeved inside the connecting frame 14 on the side of the other set of fixing frames 7. After the two sets of sleeves 8 are connected, in order to ensure that the sleeves 8 are tightly connected and that the spacing of the fixing frames 7 is fixed, the personnel pass the side of the steel wire rope 11 through the limiting frame 15 and insert it into the inside of the connecting frame 14, and the stopper 13 abuts against the upper end of the connecting frame 14. At this time, the telescopic spring 12 is in a compressed state, ensuring that the steel wire rope 11 can block the contact of foreign objects with the nut 10. At the same time, the tension of the steel wire rope 11 maintains the distance between the two sets of fixing frames 7, further assisting in maintaining the stability of the connection between the nut 10 and the two sets of sleeves 8.

[0031] As a technical optimization of this utility model, the end of the connecting frame 14 is provided with a limiting frame 15 for locking the wire rope 11. The limiting frame 15 can prevent the wire rope 11 from coming out of the circular slot inside the connecting frame 14. The connecting frame 14 has a circular slot inside, and the diameter of the circular slot is equal to the cross-sectional diameter of the wire rope 11, ensuring that the wire rope 11 can be locked into the inside of the connecting frame 14.

[0032] As a technical optimization of this utility model, the wire rope 11 is configured as four groups, and the wire rope 11 is evenly arranged on the outside of the fixing frame 7. The center part of the wire rope 11 is configured with a texture. The texture of the wire rope 11 can be easily deformed when subjected to external impact, and is not prone to breakage.

[0033] As a technical optimization of this utility model, the limiting frame 15 is made of soft material. When the personnel pass the steel wire rope 11 through the limiting frame 15, the limiting frame 15 will be deformed by force so that it passes through and enters the circular slot inside the connecting frame 14. The bottom end of the stop 13 is in contact with the upper surface of the connecting frame 14. The setting of the stop 13 and the telescopic spring 12 ensures that there is a fixed range of extensibility between the fixed frame 7 and ensures the stability of the connection part of the fixed frame 7.

[0034] The working principle of this utility model is as follows: First, the operator inserts the feeder cable into the interior of a set of chassis 1. Before insertion, the lever 4 is pushed onto the top of chassis 1, causing the lever 4 to rotate the first rotating frame 5 and the second rotating frame 6, making them vertically aligned. This provides space for the feeder cable to enter the internal channel of chassis 1, making the operation faster and more convenient, quickly determining the position between the feeder cable and chassis 1. Then, the end of the feeder cable is inserted into the inner wall of the sleeve 8, and the lever 4 is released. The deformation of the extension spring 3 pushes the lever 4 away from the inner wall. The base 1 and the lever 4 push the connecting end of the flip frame 5 upward, reducing the angle between the flip frame 5 and the flip frame 6. The connecting part of the flip frame 5 and the flip frame 6 will contact the feed line inside the protective plate 2, thereby fixing the position of the feed line and the base 1, realizing the quick connection of the feed line and the overall equipment. The same principle can be used to fit the antenna inside the other set of sleeves 8. Then, the ports of the two sets of sleeves 8 are attached, and the nut 10 is rotated to the attached part to connect the two sets of sleeves 8, and the feed line and the antenna can be quickly connected.

In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
