Technical Field

[0001] The utility model belongs to the technical field of wireless signals in subway tunnels, specifically to the technical field of a wireless signal enhancement device in subway tunnels. Background Art

[0002] At present, the urban subway tracks are developing rapidly, and the environment in the subway tunnel is complex, including characteristics such as terrain, signal transmission being blocked, and dense population. Therefore, the demand for wireless signal enhancement devices in the subway is increasing day by day. These factors pose great challenges to the propagation and reception of wireless signals. Thus, there are wireless signal enhancement devices. However, the current wireless signal enhancement devices in subway tunnels still have drawbacks. Due to external environmental factors, wires are prone to loosening or even falling off. During the installation process, stability cannot be maintained, the wires inside the device are prone to slackening, and dust or debris may be brought during the train's operation, easily damaging some of the wires outside the device.

[0003] Due to the narrow space and complex environment in the tunnel, the wireless signal enhancement device needs to be firmly fixed on the tunnel wall or other suitable positions to ensure its stability and safety. This usually involves fixing and stabilizing the wires. As a closed and narrow space, the subway tunnel requires a technology for fixing and stabilizing the wires of the wireless signal enhancement device, which lies in ensuring the firmness and safety of the wires in the tunnel. Due to the complex tunnel environment with adverse factors such as vibration and humidity, the wires must adopt reliable fixing methods to prevent falling off or damage. The fixing of the wires in the air or on the ground must be firm enough to withstand stress changes caused by irresistible factors. Summary of the Utility Model

[0021] 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 of the embodiments. Based on the embodiments of 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.

[0022] Such as Figures 1 to 6As shown in the figure, the utility model provides a wireless signal enhancement device in a subway tunnel, which includes a base 1. A baffle 2 is fixedly installed on the top surface of the base 1. A guard plate 4 is arranged on one side of the base 1, and a rotating shaft 3 is arranged at the contact point between the base 1 and the guard plate 4. The base 1 is hinged to the guard plate 4 through the rotating shaft 3. A fixator 17 is fixedly installed at one end of the guard plate 4. A telescopic rod 12 is movably connected inside the fixator 17. A spring 13 is sleeved on the outer wall of the telescopic rod 12. A stopper 11 is fixedly installed at one end of the telescopic rod 12 close to the guard plate 4. A pull rod 14 is fixedly installed at one end of the telescopic rod 12 away from the stopper 11. A wire pipe 5 is fixedly installed inside the baffle 2. A pressing ring 6 is sleeved on the outer wall of the wire pipe 5. A compressor 7 is placed on the outer wall of the pressing ring 6. A spring piece 10 is arranged inside the compressor 7. A fixed shaft 8 is arranged inside the spring piece 10. An rubber ring 9 is sleeved on the outer wall of the fixed shaft 8 away from the fixator 17.

[0023] As Figure 4 shown, six compressors 7 are symmetrically arranged, and the appearance shape is an irregular curved shape. The compressor 7 is made of metal.

[0024] Adopting the above scheme: By flipping the guard plate 4, when the outer wall of the guard plate 4 touches the top end of the compressor 7 during the flipping process, the compressor 7 will rotate around the fixed shaft 8 until it clamps the wire pipe 5.

[0025] As Figure 5 shown, the spring piece 10 has a circular appearance and is made of stainless steel.

[0026] Adopting the above scheme: Through the rotation of the compressor 7, the elastic force of the spring piece 10 reversely rotates the spring piece 10 to loosen the wire pipe 5. The stainless steel material can avoid the problem of rust and rotation pause of the spring piece 10 during use.

[0027] As Figure 6 shown, the pull rod 14 is in a "mouth" shape and is made of rubber. One end of the telescopic rod 12 extends through the fixator 17.

[0028] Adopting the above scheme: Through the "mouth" shape design, the operator can conveniently pull it. The rubber appearance can ensure that damage is avoided during the pulling process. By passing the telescopic rod 12 through the fixator 17, the stopper 11 can move back and forth freely.

[0029] As Figure 2 shown, a groove 15 is opened inside one end of the base 1 away from the rotating shaft 3.

[0030] Adopting the above scheme: It is limited by the rubber ring 9 to prevent the compressor 7 from falling off during rotation. The rubber material plays a buffering role, and each size is the same to avoid damage.

[0031] As Figure 3As shown, the inside of the baffle 2 and the guard plate 4 is provided with cavities, and there are three cavities.

[0032] With the above solution: By designing the cavities, the wire pipe 5 can freely extend after the baffle 2 and the guard plate 4 are closed, preventing the position of the wire pipe 5 from being disordered.

[0033] As Figure 1 shown, a signal transmitter 16 is fixedly installed at one end of the base 1 away from the baffle 2, and the appearance of the signal transmitter 16 is trapezoidal.

[0034] With the above solution: Through the signal transmitter 16, the device receives signals during use and enhances the signal strength according to its own enhancement module, avoiding weak signal transmission rate in the track and inability to be used normally.

[0035] The working principle and usage process of the present utility model:

[0036] First, the operator pulls the pull rod 14 outwards. The pull rod 14 will drive the telescopic rod 12 to slide outwards. The telescopic rod 12 will compress the spring 13. Subsequently, the telescopic rod 12 pulls the stop block 11. When the stop block 11 leaves the baffle 2, the pull rod 14 is pulled upwards again. At this time, the pull rod 14 drives the fixator 17, and the fixator 17 drives the guard plate 4 to flip with the rotating shaft 3 as the center point;

[0037] Second, when the guard plate 4 flips to an appropriate position, the operator connects the wire to the wire pipe 5, and then tightens the pressing ring 6. After each pressing ring 6 is tightened, the pull rod 14 is pulled again. The pull rod 14 will drive the fixator 17, and the guard plate 4 follows the fixator 17 to flip;

[0038] Finally, when the guard plate 4 flips to the position of the compressor 7, one end of the guard plate 4 touches the compressor 7. The compressor 7 rotates around the fixed shaft 8 until it clamps the wire pipe 5. The pull rod 14 is released. At this time, the stop block 11 is pushed into the groove 15 automatically by the elastic force of the spring 13 to achieve the fixing effect. Then the signal transmitter 16 is started, and the signal transmitter 16 receives and enhances the signal.

[0039] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0040] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
