Description

Technical Field

[0001] This utility model belongs to the field of fire alarm detection technology, specifically an aircraft fire alarm detection test box. Background Technology

[0002] Airplanes are one of the most important means of transportation in modern society. Because airplanes fly in the air, it is not convenient for ground rescue operations to be carried out immediately. Once a fire occurs, it can easily lead to serious accidents. Therefore, airplanes are generally equipped with high-standard fire alarm systems. At the same time, it is necessary to conduct comprehensive inspections and maintenance of the fire alarm systems regularly to ensure that they are kept in good condition. In this process, the airplane fire alarm detection test kit is needed.

[0003] Existing aircraft fire alarm detection test boxes test the response of fire alarm systems by simulating electrical signals. During the test, multiple subsystems of the fire alarm system, such as the fire alarm system and the fire extinguishing circuit, need to be connected via connecting cables. Therefore, during wiring or subsequent operation through the test box, some connecting cables will inevitably be pulled, which can easily cause loosening or even damage to the connections. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an aircraft fire alarm detection test box, which solves the problem that existing aircraft fire alarm detection test boxes are prone to pulling on some connecting wires during connection to the fire alarm system or use, resulting in loosening or even damage at the connection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aircraft fire alarm detection test box, comprising a test box body, wherein the top of the test box body is evenly provided with mounting grooves, and a movable block is provided inside the mounting grooves; a spring is connected between the movable block and the test box body; a connecting socket is installed through the top of the movable block, and the connecting socket is electrically connected to the test box body through an elastic connecting wire.

[0006] A receiving groove is provided on one side of the movable block, and a blocking mechanism for blocking the movable block is provided in the mounting groove.

[0007] The test box body is equipped with a shielding mechanism for protecting the connection socket.

[0008] As a further embodiment of this utility model: both sides of the top of the movable block are set with bevels, and the movable block and the mounting groove form a relative sliding structure.

[0009] As a further embodiment of this utility model: the blocking mechanism includes a fixing plate, which is installed inside the mounting groove on the side near the receiving groove, and the fixing plate extends into the receiving groove. An opening compartment is installed at the bottom of the fixing plate, and a whistle is installed through one side of the opening compartment. An airbag is installed at the bottom of the fixing plate, and opening slots are provided at the top and bottom of the airbag.

[0010] As a further embodiment of this utility model: the cross-sectional area of ​​the airbag is the same as the cross-sectional area of ​​the opening compartment, and the airbag is fixedly connected to the opening compartment by adhesive.

[0011] As a further embodiment of this utility model: the shielding mechanism includes an L-shaped mounting rod, which is mounted on the test box body on the side of the mounting groove, and a protective cover is sleeved on the outside of the L-shaped mounting rod.

[0012] As a further embodiment of this utility model: the protective cover and the L-shaped mounting rod are slidably connected, and a finger groove is provided on the top of the protective cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The connection socket is installed on the movable block. When subjected to slight pulling, the movable block can slide to reduce the impact of the pulling force on the connection and wires. At the same time, a blocking mechanism is set in the mounting groove. When the pulling continues after a slight pulling, the bottom part of the receiving groove can compress the airbag. At this time, the movable block can slide further to reduce the impact of the pulling force. The air in the airbag will be squeezed into the opening chamber and discharged through the whistle. The whistle will then emit a sharp whistle to remind the staff not to continue pulling, so as to prevent the staff from continuing to pull without knowing that it may cause the connection to loosen or even be damaged.

[0015] 2. The test box body is equipped with a shielding mechanism, and the top two sides of the movable block are beveled. When not in use, the protective cover can be slid and pressed upwards towards the corresponding movable block until the protective cover is directly above the movable block. At this time, the movable block presses upwards to create a pre-tightening force between the protective cover and the protective cover, so that the protective cover is basically fixed in this position. This can protect the connection socket when not in use, and prevent the connection socket from being easily contaminated and affecting subsequent use. Attached Figure Description

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Example 1

[0025] like Figures 1-6 As shown, this utility model provides a technical solution:

[0026] An aircraft fire alarm detection test box includes a test box body 1, which is the same as existing similar equipment and tests the response of the aircraft fire alarm system by simulating electrical signals.

[0027] The top of the test box body 1 is evenly provided with mounting grooves 2, and the inside of the mounting grooves 2 is provided with movable blocks 3. The movable blocks 3 are connected to the test box body 1 by springs 4. The top of the movable blocks 3 is installed with a connecting socket 5, and the connecting socket 5 is electrically connected to the test box body 1 through an elastic connecting wire 6. Both sides of the top of the movable blocks 3 are set with bevels, and the movable blocks 3 and the mounting grooves 2 form a relative sliding structure. Under normal conditions, the length of the elastic connecting wire 6 has a certain redundancy, so that when the operator inserts the connecting wire into the connecting socket 5 and inserts the connecting wire into the fire alarm system, or when the connection is pulled by the test box body 1 after the connection is completed, the movable blocks 3 can slide inside the mounting grooves 2 to reduce the pulling force on the connection or the connecting wire.

[0028] The movable block 3 has a receiving groove 7 on one side. The mounting groove 2 is equipped with a blocking mechanism to block the movable block 3. The blocking mechanism includes a fixing plate 8, which is installed inside the mounting groove 2 on the side close to the receiving groove 7 and extends into the receiving groove 7. An opening 9 is installed at the bottom of the fixing plate 8, and a whistle 10 is installed through one side of the opening 9. An airbag 11 is installed at the bottom of the fixing plate 8, and opening grooves 12 are opened at the top and bottom of the airbag 11. When the operator inserts the connecting wire into the connecting socket 5, the operator can use the insertion force to push the movable block 3 downward and slide it until the top part inside the receiving groove 7 forms a block with the fixing plate 8. At this time, the movable block 3 cannot move downward, and the operator can smoothly insert the connecting wire into the connecting socket 5. When pulling out the connecting wire, the operator can use their fingers to press the rest of the movable block 3 to prevent the movable block 3 from moving and thus smoothly pull out the connecting wire.

[0029] When the connecting cable is pulled beyond a certain range during connection or testing, the bottom part of the receiving groove 7 will compress the airbag 11. At this time, the movable block 3 can still reduce the impact of the pulling force on the connecting cable or the connection point by sliding, but the air in the airbag 11 will be squeezed into the opening chamber 9. The air in the opening chamber 9 will be discharged through the whistle 10, and the whistle 10 will produce a sharp whistling sound, so as to promptly remind the staff not to continue to pull the connecting cable, so as to avoid the connection point from becoming loose or even damaged.

[0030] The cross-sectional area of ​​the airbag 11 is the same as that of the opening chamber 9, and the airbag 11 is fixedly connected to the opening chamber 9 by adhesive, ensuring the connection strength during use, and that when the airbag 11 is squeezed, enough air enters the interior of the opening chamber 9 and is discharged through the whistle 10 to produce a whistling sound.

[0031] Example 2

[0032] Based on the above embodiment 1, as Figures 1-6 As shown, the test box body 1 is provided with a shielding mechanism for protecting the connection socket 5. The shielding mechanism includes an L-shaped mounting rod 13, which is installed on the side of the test box body 1 on the mounting groove 2. A protective cover 14 is sleeved on the outside of the L-shaped mounting rod 13. In the normal state, the protective cover 14 is located directly above the corresponding movable block 3. At this time, the spring 4 is in a slightly compressed state, so that there is a pre-tightening force between the movable block 3 and the corresponding protective cover 14, so that the protective cover 14 can be basically fixed in this position, thereby protecting the opening of the connection socket 5 and preventing it from being easily contaminated and affecting subsequent use.

[0033] When needed, the protective cover 14 can be slid out from directly above the movable block 3. At this time, the edge of the bottom groove of the protective cover 14 can be pressed against the inclined part of the movable block 3, so that the movable block 3 can slide further into the mounting groove 2, allowing the protective cover 14 to be slid until the protective cover 14 completely releases the pressure on the movable block 3. Similarly, after use, the protective cover 14 can be moved towards the corresponding movable block 3 until the protective cover 14 is above the corresponding movable block 3 and generates a pre-tightening force with it. The whole operation process is convenient and quick.

[0034] The protective cover 14 and the L-shaped mounting rod 13 are slidably connected, and the top of the protective cover 14 is provided with a finger groove 15 to ensure that the protective cover 14 can be slid under human operation and can be operated through the finger groove 15. Furthermore, the inside of the finger groove 15 can be provided with anti-slip texture.

[0035] The working principle of this utility model is as follows: The device is powered by a storage battery or an external power source. When in use, the protective cover 14 on the corresponding movable block 3 is slid to release the protective pressure on it as needed. The prepared connecting wire is inserted into the connecting socket 5, and then the other end of the connecting wire is connected to the fire alarm system. The test box body 1 sends a simulated electrical signal to the fire alarm system to test the response of the fire alarm system. During the above wiring and operation through the test box body 1, when there is a small pull on the connecting wire, the movable block 3 can extend the connecting wire by its own sliding to reduce the impact on the connection and the connecting wire itself. When there is a larger pull, the movable block 3 can slide further to reduce the impact. At the same time, the part at the bottom of the receiving groove 7 can squeeze the airbag 11, so that the whistle 10 emits a sharp whistling sound to alert the staff and prevent the staff from continuing to pull without knowing it.

[0036] After use, disconnect the connecting cable and then slide the protective cover 14 directly above the corresponding movable block 3. At this time, a pre-tightening force is generated between the movable block 3 and the corresponding protective cover 14, so that the protective cover 14 is basically fixed in this position, and the protective cover 14 maintains the protection of the connecting socket 5.

[0037] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
