[0002] Rescue refers to the entire process of implementing rescue operations for individuals or people when they encounter disasters or other extraordinary situations; and the rescue business refers to the affairs that can be prepared for a long time and can implement rescue operations in a timely manner anytime and anywhere; when faced with different rescue difficulties, rescue can be carried out through mechanization, and the emergence of drones can just meet the needs of rescue surveys. The rational use of drones can achieve good rescue results.

[0003] At present, when existing drones are transporting rescue items, they generally adopt the method of hanging the rescue items for transportation. However, due to the changeable flight conditions of the drone and the influence of airflow, the hung items are easily shaken during transportation, causing the items to be unstable and fall, affecting the rescue work. For this reason, we propose a hanging mechanism for a drone used for fire investigation and rescue. Summary of the invention

[0004] The purpose of the present invention is to provide a hanging mechanism for a fire investigation and rescue drone to solve the existing problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a hanging mechanism of a drone for fire investigation and rescue, comprising a drone main body, a push plate and a pressure plate, wherein landing gears are fixedly installed on both sides of the bottom of the drone main body, and a support plate is arranged on the inner side of the bottom end of the landing gear, a main slide groove is longitudinally opened at the middle end of the bottom of the drone main body, a driving screw is arranged inside the main slide groove, and a threaded block is spirally connected to the outer periphery of the driving screw, and an L-shaped push plate is slidably arranged at the bottom of the drone main body, the top of the push plate is fixedly connected to the threaded block, a driving groove is opened on the inner top wall of the push plate, a bidirectional screw is arranged inside the driving groove, and moving blocks are sleeved on the outer periphery of both ends of the bidirectional screw, and the moving block is spirally connected to the two ends of the bidirectional screw through a threaded sleeve embedded inside, a push rod is arranged at the bottom of the moving block, and a pressure plate is arranged at the bottom of the push rod, and the two ends of the push rod are respectively movably connected to the moving block and the pressure plate through a movable connecting seat.

A second motor is provided at one end of the bidirectional screw, and the second motor is fixedly embedded in the inner wall of one end of the driving groove.

[0008] Preferably, auxiliary slide grooves are provided on both sides of the bottom of the drone body, a limit slide rod is fixedly installed inside the auxiliary slide groove, a sliding sleeve is provided on the peripheral sliding sleeve of the limit slide rod, and the bottom of the sliding sleeve is fixedly connected to the top of the push plate.

[0009] Preferably, the inner walls on both sides of the driving groove are provided with limiting grooves, and limiting blocks are arranged on both sides of the moving block. The limiting blocks extend into the limiting grooves and are slidably connected with the inner walls thereof.

[0010] Preferably, an anti-skid pad is provided at the bottom of the buffer sleeve, and the anti-skid pad is fixed to the bottom of the buffer sleeve by gluing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting a support plate at the bottom end of the landing gear, cooperating with the pressure plate provided on the inner top wall of the push plate, and using a bidirectional screw to drive the moving block to move one end of the push rod, so that the other end pushes the pressure plate downward, the materials or equipment can be compacted, thereby ensuring the stability of the materials or equipment and avoiding shaking or falling. In addition, the driving screw, threaded block and push plate can be used to realize the taking, placing or delivery of materials or equipment, so that the stability of the materials or equipment during transportation is ensured while the portability of the taking and placing of the materials or equipment is improved.

[0015] 2. By setting a buffer sleeve at the bottom of the pressure plate and cooperating with a buffer spring, the function of buffering between the pressure plate and the materials or equipment is realized to avoid excessive pressure on the materials or equipment during the compaction process, which may cause damage to the materials or equipment, thereby ensuring the safety of the materials or equipment.

[0016] 3. By setting an anti-skid pad at the bottom of the buffer cover, the friction between the buffer cover and the materials or equipment is increased by using the anti-skid pad to avoid the materials or equipment from slipping due to their smooth surface, causing the buffer cover to fall accidentally.
