Description

Technical Field

[0001] This utility model relates to the field of aviation safety, specifically an explosion-proof enclosure for aircraft fuel system signal acquisition. Background Technology

[0002] The explosion-proof enclosure for aircraft fuel system signal acquisition is primarily used for data acquisition and transmission in explosion-proof environments. It ensures the safe operation of the fuel system under extreme conditions such as high temperature and high pressure. The enclosure adopts an intrinsically safe design, adaptable to the high temperature and high pressure environment of aviation fuel systems, avoiding the risk of explosion due to electrical component failure. By integrating a domestically produced PXIe data acquisition system, industrial control computer, and other equipment, it monitors key parameters of the fuel system in real time, such as temperature, pressure, and level, providing pilots with flight status feedback and ensuring the stability and safety of fuel supply. The acquired data supports remote monitoring and maintenance of the fuel system, enabling timely detection of potential hazards such as leaks and fuel pump failures, reducing maintenance costs and improving flight safety.

[0003] However, the existing explosion-proof enclosures for aircraft fuel system signal acquisition still have the following problems during use:

[0004] In order to install electrical components and connecting wires in existing explosion-proof enclosures, the assembly frame is usually hinged to the inner wall of the enclosure, allowing the assembly frame to deflect. Due to the poor stability of the assembly frame, the assembly frame is prone to shaking during the installation of electrical components and connecting wires, increasing the assembly difficulty and causing great inconvenience to operation. Therefore, explosion-proof enclosures for aircraft fuel system signal acquisition are very necessary in the field of aviation safety. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, such as the poor stability of existing assembly frames, which cause the assembly frame to wobble during the installation of electrical components and connecting wires, increasing the difficulty of assembly and causing great inconvenience to operation, this utility model proposes an explosion-proof housing for aircraft fuel system signal acquisition.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an explosion-proof enclosure for aircraft fuel system signal acquisition, comprising:

[0007] The main body of the explosion-proof signal acquisition enclosure has an assembly chamber. Multiple bearing blocks are fixedly mounted on the inner wall of the assembly chamber. Each bearing block is hinged with an assembly frame. Each assembly frame has a traction groove on its top and a telescopic cavity inside the assembly frame, which is located below the traction groove.

[0008] The snap-fit ​​mechanism includes a push rod, which is movably assembled with the traction groove and the telescopic cavity respectively. One end of the push rod movably passes through the assembly frame, and a push plate is fixedly assembled on the top of the push rod. The push plate is movably assembled with the traction groove. A connecting plate is fixedly assembled on the push rod. The connecting plate is movably assembled with the telescopic cavity. A telescopic spring is assembled on the push rod. Both ends of the telescopic spring are fixedly assembled with the bottom surface of the connecting plate and the telescopic cavity respectively.

[0009] The traction mechanism includes a vertical block, the top of which is fixedly fitted with a support block, which is located above the push plate.

[0010] Preferably, each of the assembly frames is fixedly equipped with multiple support frames, each of which is provided with mounting holes, and the traction groove and telescopic cavity are located on one side of the support frame.

[0011] Preferably, an operating block is fixedly mounted on the support block, the operating block has a rotating cavity inside, traction cavities are symmetrically arranged on the rotating cavity, and an internally threaded sleeve is movably mounted on the rotating cavity.

[0012] Preferably, the internal threaded sleeve rod movably passes through the operating block and the support block, and the internal threaded sleeve rod is located above the push plate. Sliding blocks are symmetrically fixedly assembled on the upper surface of the internal threaded sleeve rod, and the sliding blocks are movably assembled with the traction cavity.

[0013] Preferably, a transmission screw is movably mounted on the rotating cavity, and the transmission screw is threadedly assembled with an internally threaded sleeve.

[0014] Preferably, one end of the transmission lead screw movably passes through the operating block, and a knob is fixedly mounted on one end of the transmission lead screw.

[0015] Preferably, a fixing block is fixedly mounted on the inner wall of the assembly chamber, and a fixing groove is provided on the fixing block. A lock is mounted on the assembly frame, and the lock engages with the fixing groove on the fixing block.

[0016] Preferably, the explosion-proof signal acquisition enclosure has a hinged door.

[0017] The advantages of this utility model are:

[0018] This invention utilizes a knob to rotate a transmission screw on an internally threaded sleeve, causing a sliding block to move between two traction chambers. The internally threaded sleeve moves downwards, pushing a lower push plate. This push rod moves a connecting plate, causing a telescopic spring to contract. One end of the push rod passes through the assembly frame and pushes against the lower push plate, ensuring the stability of multiple assembly frames even when interlocked. This facilitates the installation of electrical components and connecting wires. After installation, the assembly frame is deflected on a bearing block, positioning its end face on one side of the fixing groove of the fixing block. Operating the lock then engages the fixing groove on the fixing block, improving the stability between the assembly frame and the fixing block. This also facilitates the placement of electrical components and connecting wires within the assembly chamber, enhancing operational efficiency. Attached Figure Description

The signal acquisition explosion-proof housing body 10 is equipped with a traction mechanism 41. The traction mechanism 41 includes a vertical block 4101. The top of the vertical block 4101 is fixedly assembled with a support block 4102. The support block 4102 is located above the push plate 4004.

[0034] In this utility model, multiple assembly frames 20 are flipped on the support block 13 to press the uppermost push plate 4004, causing the push rod 4001 to drive the connecting plate 4002 to move, and the telescopic spring 4003 to retract. One end of the push rod 4001 passes through the assembly frame 20, and the push rod 4001 pushes the lower push plate 4004, thereby making the multiple assembly frames 20 stable when they are interlocked, which facilitates the installation of electrical components and connecting wires.

[0035] Reference Figure 4 and Figure 5 An operating block 4103 is fixedly mounted on the support block 4102. The operating block 4103 has a rotating cavity 4106 inside. A traction cavity 4107 is symmetrically arranged on the rotating cavity 4106. An internally threaded sleeve 4104 is movably mounted on the rotating cavity 4106.

[0036] In this utility model, multiple assembly frames 20 are flipped on the bearing block 13 respectively, and the knob 4105 is turned, so that the transmission screw 4109 rotates on the internal thread sleeve 4104, causing the sliding block 4108 to move on the two traction chambers 4107, and the internal thread sleeve 4104 moves downward, pushing the push plate 4004 below.

The lock 31 is operated so that the fixing groove 30 on the fixing block 23 is inserted, thereby improving the stability between the assembly frame 20 and the fixing block 23.

[0039] Working principle: Multiple assembly frames 20 are flipped on the bearing block 13, turning the knob 4105, causing the transmission screw 4109 to rotate on the internal threaded sleeve 4104, allowing the sliding block 4108 to move on the two traction chambers 4107. The internal threaded sleeve 4104 moves downward, pushing the push plate 4004 below. The push rod 4001 drives the connecting plate 4002 to move, and the telescopic spring 4003 retracts. One end of the push rod 4001 passes through the assembly frame 20, and the push rod... 4001 pushes the push plate 4004 below, thereby making the multiple assembly frames 20 stable under mutual insertion, which facilitates the installation of electrical components and connecting wires. After installation, the assembly frame 20 is deflected on the support block 13 so that the end face of the assembly frame 20 is located on one side of the fixing groove 30 of the fixing block 23. The lock 31 is operated so that the fixing groove 30 on the fixing block 23 is inserted, which improves the stability between the assembly frame 20 and the fixing block 23, and facilitates the placement of electrical components and connecting wires in the assembly chamber 11, thus improving the operation efficiency.
