Description

Technical Field

[0001] The utility model relates to the field of signal receivers, in particular to an underground signal amplification and enhancement receiver for subways. Background Art

[0002] A signal receiver is a device or apparatus whose main function is to receive, pick up or capture specific signals, information or energy, such as radio waves, light waves, sound waves, etc. These signals are converted into a usable form by the receiver. The principles of the receiver include receiving signals, signal amplification, mixing, demodulation, filtering, decoding and processing. The current signal receivers have various functions such as signal amplification, signal enhancement and signal reception.

[0003] Receivers are installed on existing subways to enhance signal reception in underground passages. However, the receivers are large in size due to ear plates, which take up storage space. If the receiver is held in hand, the ear plates are easily hooked, and more wires are not convenient for carrying and installing the receiver. At the same time, the vibration caused by the passage of the subway can easily loosen the wires connected to the receiver, affecting signal reception and conversion. Utility Model Content

[0010] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0011] First, the utility model is an underground signal amplification and enhancement receiver for subways, which can facilitate the line clamping connection of the receiver. A Velcro is provided on the top of the enhancer. The staff opens the Velcro to take out the power cord, and uses the terminal of the power cord to insert the limiting tube into the connection port. In order to prevent the power cord and the transmission line from loosening and falling off, the staff pulls the clamping ring so that the opening on one side of the clamping ring is clamped on the wire tube of the power cord to limit and clamp the power cord. In addition to the power cord, the enhancer also needs to be connected to a number of transmission lines. The transmission lines are used for transmission after signal analysis. The transmission lines need to pass through the clamp and enter the connection port. An opening is provided on the top of the clamp for clamping the wire tube of the transmission line. This arrangement facilitates the fixed connection of the line and prevents the line from accidentally falling off and affecting signal reception.

[0012] Second, the utility model is an underground signal amplification and enhancement receiver for subways. Through the setting, the receiver has the ability to be stored. The staff pulls out the rubber plug in the engaging groove at the bottom of the enhancer, connects the hook with the engaging groove, and then pushes the hook to make the hook slide in the engaging groove. After the hook is installed, the rubber plug is used to close the opening on one side of the engaging groove to prevent the hook from sliding off and affecting the use. The hook is movably connected to the bottom of the enhancer and is used for hooking the transmission line, so that it is convenient to place the transmission line when it is replaced. When the enhancer is disassembled and not in use, the staff folds the ear plate, and the ear plate moves into the square groove. In order to prevent the movement of the ear plate from affecting the taking of the enhancer, a magnetic stone is set in the square groove, and the magnetic stone absorbs and positions the ear plate through magnetic force.

If the Velcro 9 is not used, the staff can use tools to remove the bolts to separate the Velcro 9 from the enhancer 1.

[0029] When in use, when installing the enhancer 1, the staff opens the ear plates 202 on both sides of the enhancer 1 through the square slots 2, uses bolts to penetrate the ear plates 202 to install the enhancer 1 on the wall, and at the same time, the staff pulls out the rubber plug 302 in the engaging slot 3 at the bottom of the enhancer 1, docks the hook 301 with the engaging slot 3, and then pushes the hook 301 to make the hook 301 slide in the engaging slot 3. After the hook 301 is installed, the rubber plug 302 is used to close the opening on one side of the engaging slot 3 to prevent the hook 301 from sliding off and affecting the use. The hook 301 is movably connected to the bottom of the enhancer 1 and is used to hook the transmission line 6, so that the transmission line 6 can be placed when it is replaced. The staff opens the Velcro 9 to take out the power cord 7, and uses the terminal of the power cord 7 to insert the limiting tube 8 into the connecting port 4. In order to avoid the power cord 7 from contacting the transmission line 6 If the wire 6 becomes loose and falls off, the staff pulls the locking ring 801 so that the opening on one side of the locking ring 801 is engaged with the wire tube of the power line 7 to limit the power line 7. In addition to the power line 7, the enhancer 1 also needs to be connected to a number of transmission lines 6. The transmission lines 6 are used for transmission after signal analysis.
