Description

Technical Field

[0001] The utility model relates to a novel aircraft trip switch locking device. Background Art

[0002] The main functions of the aircraft jumper are: 1. When a large current appears in the aircraft circuit, the jumper will jump out, cut off the power supply of the aircraft circuit, and protect the aircraft's lines and electrical equipment; 2. When used for aircraft maintenance, manually pulling out the jumper can cut off the power supply of the system that needs maintenance, which is used to protect maintenance personnel, prevent accidental electric shock to construction workers, and prevent accidental operation of electrical equipment; 3. When a fault occurs in the aircraft, manually pulling out the jumper will cut off the power supply of the faulty system, making the faulty system stop working, and preventing the faulty system from affecting the normal flight of the aircraft.

[0003] When the circuit breaker needs to be manually pulled out, in order to prevent the circuit breaker from being pressed in by others other than the construction worker, or being touched by other persons or objects, so that the circuit breaker is accidentally closed, the maintenance worker needs to install the circuit breaker clip 7 (a circuit breaker locking device) on the pulled-out circuit breaker 1 after pulling out the circuit breaker to prevent the circuit breaker 1 from being pressed and closed.

[0004] The existing jumper clamp 7 is made of plastic, has elasticity, and is in the shape of a circular ring with a notch 701 on one side. Figure 6 As shown, during installation, the gap 701 needs to be enlarged, and then the circuit breaker clamp 7 is put on the circuit breaker 1. After the circuit breaker clamp 7 is released, the circuit breaker clamp 7 will shrink the gap 701 due to its own elasticity, thereby clamping on the circuit breaker 1. The inner diameter of the circuit breaker clamp 7 is smaller than the outer diameter of the crown part 101 of the circuit breaker, so when an external force is applied to the crown part 101 of the circuit breaker, the circuit breaker clamp 7 will hinder the circuit breaker 1 from moving in the closing direction, thereby preventing the circuit breaker 1 from being closed.

[0005] However, the current jumper clamp has the following shortcomings:

[0006] 1. The existing circuit breaker clamp 7 has a notch 701. When the notch 701 is facing upward, the circuit breaker clamp 7 may be accidentally touched by a downward force, and the circuit breaker clamp 7 may fall off the circuit breaker 1.

[0007] 2. The outer shape of the jumper clamp 7 is a circular ring with a small surface area, which makes it inconvenient to record the number code, constructor information, and maintenance process management information on the outer surface.

[0008] 3. When the aircraft is in overhaul state, many jumpers need to be pulled out. The existing jumper clip 7 has the disadvantages of being inconvenient to borrow, return and count, and inconvenient to count in place. Utility Model Content

[0009] The utility model aims to provide a novel aircraft trip switch locking device, which can lock the aircraft trip switch more stably.

[0010] The purpose of the utility model is achieved through the following technical solutions:

[0011] A novel aircraft trip switch locking device is characterized in that it includes a sleeve, a U-shaped clip, a locking nut and a radio frequency identification chip. The sleeve is provided with a radially penetrating receiving groove, the U-shaped clip is embedded in the receiving groove, the clamping mouth of the U-shaped clip is aligned with the tube mouth of the sleeve, the outer wall of the sleeve is provided with an external thread, the locking nut is cooperatively connected to the sleeve, when the locking nut moves to the clamping mouth position of the U-shaped clip, the clamping mouth of the U-shaped clip will be compressed and become smaller, and the radio frequency identification chip is installed in the sleeve.

[0012] Furthermore, both side edges of the U-shaped clamp are respectively provided with elastic clamp arms, and the ends of the clamp arms located at the clamp opening are provided with clamp blocks protruding inwards.

[0013] Furthermore, the aircraft jump switch locking device also includes a fixing pin, a radial first mounting hole is provided at the end of the sleeve away from its barrel mouth, a second mounting hole is provided at the end of the U-shaped clip away from its bayonet, the first mounting hole is aligned with the second mounting hole, and the fixing pin is inserted into the first mounting hole and the second mounting hole.

[0014] Furthermore, two ends of the fixing pin protrude from two sides of the sleeve respectively, and the protruding parts of the fixing pin are used to block the movement of the locking nut.

[0015] Furthermore, an installation cavity is provided at the end of the sleeve away from the sleeve opening, and the radio frequency identification chip is embedded and installed in the installation cavity.

[0016] Furthermore, the radio frequency identification chip is adhered to the inner wall of the installation cavity.

[0017] Furthermore, a friction groove is provided on the side surface of the locking nut.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] When the utility model is used, the crown part of the trip switch is completely covered by the sleeve, and the clamping opening of the U-shaped clip is compressed and reduced by the locking nut, so that the clamping opening of the U-shaped clip can be stably clamped on the crown part of the trip switch, and the fixing nut can provide a large clamping force, so that the locking device is difficult to loosen even when it is touched by external forces in various directions, and is more stable. When the sleeve covers the crown part of the trip switch, the trip switch can no longer be pressed in.

[0020] The utility model also arranges a radio frequency identification chip in the sleeve, and the radio frequency identification chip can record information, and can provide hardware conditions for establishing a relevant management platform (software), so as to realize the functions of recording and checking number codes, constructor information, maintenance process management information and the like, and realize the functions of quickly counting the return and loan of aircraft jump switch locking devices, and quickly counting the in-place aircraft jump switch locking devices.

[0033] Example:

[0034] like Figures 1 to 3 The novel aircraft trip switch locking device of this embodiment is shown, which includes a sleeve 3, a U-shaped clip 5, a locking nut 2, a fixing pin 6 and a radio frequency identification chip 4 (RFID chip).

[0035] The sleeve 3 of this embodiment is a cylinder, one end of which is a barrel opening 304 and the other end is closed, and the inner diameter of the barrel opening 304 is larger than the outer diameter of the crown portion 101 of the trip switch 1. The sleeve 3 is provided with a radially penetrating receiving groove 303, and the outer wall is provided with an external thread 301, which is used to be matched with the thread of the locking nut 2. The end of the sleeve 3 away from the barrel opening 304 is provided with a mounting cavity 302 and a radially penetrating first mounting hole 305.

[0036] The U-shaped clip 5 is a plastic clip, one end of which is a clamping opening 503. In the initial state, the clamping opening 503 is open, and the size of the clamping opening 503 when open is larger than the crown part 101 of the circuit breaker 1. Both sides of the U-shaped clip 5 are respectively provided with elastic clamping arms 501, and the ends of the clamping arms 501 located at the clamping opening 503 are provided with a clamping block 502 protruding inwardly, and the clamping block 502 is used to clamp the inner side of the crown part 101 of the circuit breaker 1. The end of the U-shaped clip 5 away from its clamping opening 503 is provided with a second mounting hole 504.

[0037] The U-shaped clip 5 is embedded in the receiving groove 303, the clamping mouth 503 of the U-shaped clip 5 is aligned with the barrel mouth 304 of the sleeve, the first mounting hole 305 is aligned with the second mounting hole 504, and the fixing pin 6 is inserted into the first mounting hole 305 and the second mounting hole 504, so as to install the U-shaped clip 5 in the receiving groove 303.

[0038] The locking nut 2 is threadedly connected to the sleeve 3, and the locking nut 2 can be moved between the two ends of the sleeve 3 by rotating. The two ends of the fixing pin 6 protrude from the two sides of the sleeve 3 respectively, and the protruding part of the fixing pin 6 is used to block the movement of the locking nut 2. When the locking nut 2 moves toward the end of the sleeve 3 away from its barrel mouth 304, it will eventually hit the protruding part of the fixing pin 6, thereby limiting the movement of the locking nut 2. When in use, when the locking nut 2 moves to the clamping opening 503 position of the U-shaped clamp 5, the locking nut 2 will compress the two clamping arms 501 of the U-shaped clamp 5 toward the middle, so that the clamping opening 503 is compressed and becomes smaller.

[0039] The RFID chip 4 is embedded in the installation cavity 302 and pasted on the inner wall of the installation cavity 302. The RFID chip 4 can record information and provide hardware conditions for establishing a relevant management platform (software), thereby realizing the functions of recording and checking the number code, constructor information, maintenance process management information, etc., and realizing the functions of quickly counting the return and loan of the aircraft jump switch locking device and quickly counting the jump switch locking devices in place.

[0040] In this embodiment, a friction groove 201 is provided on the side surface of the locking nut 2 , and the friction groove 201 can increase the friction force and facilitate manual rotation of the locking nut 2 .

[0041] like Figure 4 and Figure 5 As shown, in this embodiment, when locking the pulled-out circuit breaker 1, the sleeve 3 is put on the circuit breaker 1, and the crown part 101 of the circuit breaker 1 will be located in the sleeve opening 304 and in the clamping opening 503 of the U-shaped clamp 5, and then the locking nut 2 is rotated to move the locking nut 2 to the position of the clamping opening 503 of the U-shaped clamp 5, so that the clamping opening 503 is compressed and becomes smaller, thereby stably clamping the crown part 101 of the circuit breaker 1, and the circuit breaker 1 is locked. At this time, the circuit breaker 1 can no longer be pressed in.
