Description

Technical Field

[0001] The utility model relates to the field of signal receiving devices, and particularly relates to a power carrier receiving device with a protection structure. Background Art

[0002] A carrier wave is a technology in which a signal is loaded onto a wave with a fixed frequency during signal transmission. This process is called loading, and this fixed frequency is called the carrier frequency. The application of carrier frequencies is extensive, including but not limited to fields such as signal transmission, frequency converters, generators, and position sensorless devices. Power carrier waves are facilities for long-distance transmission of various information and monitoring and control of equipment operation in roadway construction, including various commonly used telephones and audible and visual signals, etc. Equipment using power carrier wave technology requires a receiver when controlling equipment operation. Since these receivers are inside the roadway, it is necessary to protect the receivers. In the prior art, generally a protective shell is sleeved on the receiver, but the protective shell will weaken a part of the power carrier wave and affect the power carrier wave receiving ability of the receiver, which results in it being unable to be used in places where the signal is relatively weak. Therefore, it is very necessary to propose a power carrier receiving device with a protection structure to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a power carrier receiving device with a protection structure to solve the problem that the protective shell will weaken a part of the power carrier wave and affect the power carrier wave receiving ability of the receiver, which results in it being unable to be used in places where the signal is relatively weak.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A power carrier receiving device with a protection structure, including a protective shell provided with an opening, a receiver is rotatably installed inside the protective shell, an L-shaped protective cover is rotatably installed at the opening of the protective shell, a first magnet is arranged on the bottom inner wall of the protective shell, a triangular magnet is arranged on the L-shaped protective cover, and a second magnet is arranged at one end of the receiver. The first magnet and the triangular magnet are both magnetically attracted to the second magnet.

[0005] Preferably, a wiring hole is arranged at the other end of the receiver, a through hole is opened on the L-shaped protective cover, the through hole is arranged in cooperation with the wiring hole, and a wire trough is opened on one side of the through hole.

[0006] Preferably, a reflecting plate is arranged at one end of the bottom inner wall of the protective shell, and the reflecting plate is arranged in cooperation with the receiver.

[0007] Preferably, dust-proof nets are arranged on both inner walls of the protective shell, arc-shaped side plates are arranged on both sides of the protective shell, and the two arc-shaped side plates are respectively arranged on one side of the two dust-proof nets away from each other.

[0008] Preferably, circular holes are provided on the inner walls of both sides of the protective shell, and circular protrusions are provided on both sides of the L-shaped protective cover, and the circular protrusions are snap-fitted with the circular holes.

[0009] The technical effects and advantages of the present utility model are as follows:

[0010] 1. During operation, when the signal at the usage location is relatively good, the receiving device is adjusted to the first working state. At this time, the receiver is inside the protective shell, and the second magnet on the receiver is adsorbed and fixed to the first magnet inside the protective shell. The L-shaped protective cover and the protective shell form a closed state, which can completely protect the receiver and reduce damage to the receiver from external objects.

[0011] 2. When the signal at the usage location is relatively weak, the working state is adjusted to the second working state. Rotate and open the L-shaped protective cover, and then rotate the receiver so that the second magnet on the receiver is adsorbed to the triangular magnet on the L-shaped protective cover, enabling the L-shaped protective cover to support the receiver. At this time, the L-shaped protective cover does not block the signal, making the signal receiving ability of the receiver stronger. At this time, the L-shaped protective cover is in an inclined state, which can block objects from falling directly on the receiver from the upper left of the receiver, protecting the receiver from being damaged by being smashed.

[0012] 3. When the receiving device is adjusted to the second working state, the reflector forms an angle with the signal receiver. At this time, the reflector can further enhance the signal receiving ability of the receiver, thereby improving the ability of the receiving device to receive carriers and enabling the receiving device to be used in different places.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0018] The present utility model provides a power carrier receiving device with a protection structure as Figures 1 - 3 shown, which includes a protective shell 1 provided with an opening. A receiver 2 is rotatably installed in the protective shell 1. The other end of the receiver 2 is provided with a wiring hole 7. A through hole 8 is formed in the L-shaped protective cover 3. The through hole 8 is arranged in cooperation with the wiring hole 7. A wire groove 9 is formed on one side of the through hole 8. The receiver 2 can be a common power carrier receiver on the market, so it is not limited. The receiver 2 can be connected to the controlled device through the wiring hole 7, which is convenient for the use of remote control devices. This kind of setting is a conventional setting, so it will not be elaborated.

[0019] In order to solve the problem that the protective shell will weaken a part of the power carrier, affecting the power carrier receiving ability of the receiver, which results in the inability to use in places with relatively weak signals, the present utility model rotatably installs an L-shaped protective cover 3 at the opening of the protective shell 1. A first magnet 4 is arranged on the bottom inner wall of the protective shell 1. A triangular magnet 5 is arranged on the L-shaped protective cover 3. A second magnet 6 is arranged at one end of the receiver 2. The first magnet 4 and the triangular magnet 5 are both magnetically attracted to the second magnet 6. A reflector 10 is arranged at one end of the bottom inner wall of the protective shell 1. The reflector 10 is arranged in cooperation with the receiver 2. During operation, when the signal at the use position is relatively good, the receiving device is adjusted to the first working state (as Figure 1 shown). At this time, the receiver 2 is inside the protective shell 1. The second magnet 6 on the receiver 2 is adsorbed and fixed to the first magnet 4 in the protective shell 2. The L-shaped protective cover 3 and the protective shell 1 form a closed state, which can completely protect the receiver 2 and reduce the damage of external objects to the receiver. When the signal at the use position is relatively weak, the receiving device is adjusted to the second working state (as Figure 2As shown, rotate to open the L-shaped protective cover 3, and then rotate the receiver 2 so that the second magnet 6 on the receiver 2 adsorbs to the triangular magnet 5 on the L-shaped protective cover 3, enabling the L-shaped protective cover 3 to support the receiver 2. At this time, the L-shaped protective cover 3 does not block the signal, making the signal reception ability of the receiver 2 stronger. At this time, the L-shaped protective cover 3 is in an inclined state, capable of blocking above the receiver 2 diagonally, preventing objects from falling directly onto the receiver 2, protecting the receiver 2 from being damaged, and at this time, the reflector 10 forms an angle with the signal receiver 2. At this time, the reflector 10 can further enhance the signal reception ability of the receiver 2. Therefore, the ability of the receiving device to receive the carrier wave can be improved, enabling the receiving device to be used in different places.

[0020] Dust-proof nets 11 are provided on both inner walls of the protective shell 1. Arc side plates 12 are provided on both sides of the protective shell 1, and the two arc side plates 12 are respectively arranged on one side away from each other of the two dust-proof nets 11. The dust-proof net 11 can reduce the damage of dust to the receiver 2 when the receiving device is in the first state and is convenient for heat dissipation. This kind of setting is a conventional setting, so it will not be elaborated.

[0021] Round holes are provided on both inner walls of the protective shell 1. Round protrusions are provided on both sides of the L-shaped protective cover 3. The round protrusions are snap-fitted with the round holes. When the receiving device is in the first working state, the round protrusions on the L-shaped protective cover 3 can be stuck in the round holes on the inner wall of the protective shell 1, enabling the L-shaped protective cover 3 and the protective shell 1 to be snap-fitted together and in a relatively stable state.
