Technical Field

[0001] The utility model relates to the technical field of sensor installation, and specifically relates to a sensor disassembly and assembly device. Background Technique

[0002] An E20000 sensor is installed at the cargo door of a Boeing aircraft. This sensor is located at the retracting and extending actuator of the cargo door and is installed on the frame by screwing. Since the sensor housing is close to the actuator, the disassembly and assembly space of the sensor is relatively narrow. It is difficult to disassemble and assemble this sensor with existing screwdrivers, or it is inconvenient to disassemble the wrench and the sensor after disassembly. In view of this, there is an urgent need in the market for a device that can assist in the convenient disassembly and assembly of the above sensor in a narrow space.

[0003] Therefore, the utility model provides a sensor disassembly and assembly device. Content of the Utility Model

The utility model has the function of externally disassembling and assembling the sensor, is not restricted by the installation space, and greatly improves the convenience of disassembly and assembly.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions: A sensor disassembly and assembly device includes a sensor housing. A thread is provided on the outer peripheral wall of the sensor housing near the bottom. A first driving head is fixedly arranged at the top of the sensor housing. A driving sleeve is also included. At least two driving grooves are circumferentially and evenly distributed around the first driving head on the top of the sensor housing. An annular backing plate is fixedly connected to the bottom inside the driving sleeve. One side of the annular backing plate is fixedly connected with a plug adapted to the driving groove.

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a sensor disassembly and assembly device, including a sensor housing 1. A thread 11 is provided on the outer peripheral wall of the sensor housing 1 near the bottom. The sensor is installed in the mounting hole on the frame through the thread 11 on the sensor housing 1. A first driving head 12 is fixedly arranged at the top of the sensor housing 1. When disassembling and assembling the sensor in a non-narrow area, a wrench can be used to rotate the sensor housing 1 through the first driving head 12 (internal hexagon or external hexagon structure) to realize the disassembly and assembly process of the sensor.

[0021] In this technical solution, a driving sleeve 2 is further included. At least two driving grooves 13 are circumferentially and evenly distributed on the top of the sensor housing 1 relative to the first driving head 12. A ring-shaped backing plate 3 is fixedly connected to the bottom inside the driving sleeve 2. One side of the ring-shaped backing plate 3 is fixedly connected with a plug 31 adapted to the driving groove 13. Specifically in implementation, preferably, the number of both the driving grooves 13 and the plugs 31 is three. The plug 31 is in a frustum structure, and the driving groove 13 is in a circular groove structure and is in clearance fit with the plug 31. This setting makes the docking of the driving sleeve 2 and the sensor housing 1 more convenient. After the plug 31 is inserted into the driving groove 13, controlling the rotation of the driving sleeve 2 can drive the rotation of the sensor housing 1.

[0022] A second driving head 22 is fixedly connected to the top outside the driving sleeve 2. The second driving head 22 is an external hexagon head. The setting of the driving sleeve 2 makes the second driving head 22 located outside the narrow space. At this time, using a wrench to screw the second driving head 22 can tighten the sensor housing 1, and then using a torque wrench to screw the second driving head 22 makes the sensor housing 1 in a torque-locked state. The above driving connection method between the driving sleeve 2 and the sensor housing 1 is connected by the way of the driving groove 13 and the plug 31 being hooked. Therefore, the driving sleeve 2 can be easily pulled off the sensor housing 1 after the sensor housing 1 is tightened.

[0023] In this embodiment, an anti-slip rubber sleeve 311 is fixedly sleeved on the outside of the plug 31. The function of the anti-slip rubber sleeve 311 is to protect the driving groove 13 and prevent the sensor housing 1 from being torsionally deformed.

[0024] In this embodiment, a guiding ring 4 that is rotationally and axially elastically slidably fitted is sleeved outside the driving sleeve 2. Preferably, during specific implementation, a rotating sleeve 42 is sleeved inside the guiding ring 4. The rotating sleeve 42 is sleeved outside the sensor housing 1 with a clearance and is axially slidably connected to the sensor housing 1. A rotating ring 21 near the bottom is sleeved on the outer peripheral wall of the driving sleeve 2. A tension spring 6 located between the rotating ring 21 and the rotating sleeve 42 is sleeved outside the driving sleeve 2. Two ends of the tension spring 6 are respectively fixedly connected to the rotating ring 21 and the rotating sleeve 42. One side of the guiding ring 4 is welded with a positioning ring 411 coaxial with the guiding ring 4 through a connecting shaft 41. The function of the positioning ring 411 is to assist in aligning the thread 11 on the sensor housing 1 with the mounting hole on the frame, so that the sensor housing 1 can be quickly inserted into the mounting hole on the frame.

[0025] In this embodiment, the number of the connecting shafts 41 is two and they are circumferentially and uniformly distributed relative to the guiding ring 4 to improve the strength of the positioning ring 411 against bending deformation. A rubber gasket 5 is bonded to the side of the positioning ring 411 away from the connecting shaft 41, and the rubber gasket 5 functions as a buffer.

[0026] Working principle: During use, the sensor housing 1 is sleeved into the driving sleeve 2, and then the driving sleeve 2 is held by hand to press the positioning ring 411 against the frame, so that the mounting hole on the frame is approximately located in the middle of the positioning ring 411. Then, the driving sleeve 2 is manually pressed and rotated. The plug 31 will push the sensor housing 1 to rotate through the driving groove 13. At this time, the sensor housing 1 will be smoothly inserted and screwed into the mounting hole. After pre-tightening, the driving head two 22 is rotated by using the handle, and at the same time, the driving sleeve 2 is pressed to perform the secondary screwing process on the sensor housing 1. Finally, a torque wrench is used for the tertiary screwing. Due to the action of the tension spring 6, the driving sleeve 2 can be quickly separated from the sensor housing 1 after use.

[0027] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
