Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a door lock for unmanned aerial vehicles. Background Art

[0002] Compared with manned aircraft, drones are often more suitable for tasks that are too "dull, dirty or dangerous". Drones can be divided into military and civilian use according to their application areas. In the military, drones are divided into reconnaissance aircraft and target aircraft. In the civilian field, drones + industry applications are the real rigid demand for drones; their applications in aerial photography, agriculture, plant protection, micro selfies, express transportation, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology. When the drone lands, the existing cabin door locks will be loosened due to the impact force of the drone hitting the ground, making the drone cabin door unable to be closed, resulting in the risk of items in the cabin falling. Therefore, a drone door lock is urgently needed. Utility Model Content

[0008] As an optimization, a handle corresponding to the opening is placed on one side of the door body, and the rotating shaft is passed through the reserved hole on the handle to enable the handle to rotate inward and outward of the opening.

[0009] As an optimization, a stabilizing block and a bolt slide groove are fixed on the right side of the fixing seat in sequence, and a bolt is slidably connected to the bolt slide groove, and a hook is arranged on the side of the bolt facing the fixing seat.

[0010] As an optimization, a linkage steel wire is connected between the wire locking roller and the hook, and both ends of the linkage steel wire are ring openings.

[0011] As an optimization, the ring opening on one side of the wire locking roller corresponds to the wire locking bolt and the threaded hole, and the linkage steel wire is fixed to the roller by thread locking.

[0012] As an optimization, the linkage wire is passed between the stabilizing blocks to prevent the wire from deviating when it moves left and right.

[0013] As an optimization, a spring is provided on the linkage steel wire, which can automatically reset the door bolt after the handle is released, and the spring is only provided between the stabilizing block and the ring near the hook.

[0014] As an optimization, the handle extends outward with a pull hole for easy insertion of fingers for pulling.

[0015] As an optimization, the pulling hole on the handle faces the inside of the cabin, and when the handle is not pulled, the handle is completely embedded in the opening to hide it.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the utility model are: the utility model provides a drone door lock, which can be pushed inward from the outside through a handle embedded in the opening of the door body when it needs to be opened, so that the handle rotates to drive the linkage steel wire to move toward the fixed seat side, so as to pull the door bolt to move to the left, thereby allowing the door bolt to separate from the lock body for unlocking, and the door bolt is connected by multiple structures to improve the structural strength, thereby preventing the door lock from being loosened and unable to be closed due to the impact force when the drone lands.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1-5 A drone door lock, the structure of which includes a fixed seat 2 directly connected to one side of a door body 6, and an opening is opened on the fixed seat 2, a rotating shaft 20 hinged in the fixed seat 2 and a thread locking roller 203 sleeved on one end of the rotating shaft 20, and the middle of the roller is recessed and has a threaded hole.

[0027] In this embodiment, a handle 1 corresponding to the opening is placed on one side of the door body 6, and a rotating shaft 20 is passed through a reserved hole on the handle 1 to enable the handle 1 to rotate inward and outward of the opening.

[0028] In this embodiment, the stabilizing block 3 and the bolt slide groove 4 are fixed to the right side of the fixing seat 2 in sequence, and the bolt 5 is slidably connected to the bolt slide groove 4, and a hook 72 is provided on the bolt 5 facing the fixing seat 2.

[0029] In this embodiment, a linkage wire 7 is connected between the wire locking roller 203 and the hook 72, and both ends of the linkage wire 7 are looped.

[0030] In this embodiment, the ring opening on one side of the wire locking roller 203 corresponds to the wire locking bolt 201 and the threaded hole, and the linkage wire 7 is fixed to the roller in a thread-locking manner.

[0031] In this embodiment, the linkage wire 7 is passed through the stabilizing blocks 3 so that the wire will not deviate when it moves left and right.

[0032] In this embodiment, a spring 71 is provided on the linkage wire 7 to automatically reset the bolt 5 after the handle 1 is released, and the spring 71 is only provided between the stabilizing block 3 and the ring opening close to the hook 72 .

[0033] In this embodiment, the handle 1 extends outward to have a pull hole for easy insertion of fingers for pulling.

[0034] In this embodiment, the pull hole on the handle 1 faces the inside of the cabin, and when the handle 1 is not pulled, the handle 1 is completely embedded in the opening to hide it.

[0035] When the door needs to be opened, it is only necessary to push the handle 1 inward horizontally to rotate the handle 1. At that time, because the locking wire roller 203 and the ring opening near the hook 72 are connected with the linkage wire 7, the locking wire roller 203 will rotate when the handle 1 rotates, causing the linkage wire 7 to move toward the fixing seat 2, thereby pulling the bolt 5 to the left, so that the bolt 5 is separated from the lock body, and the drone door can be opened;

[0036] The overall lock body is fixed using a variety of structures, which can effectively prevent the bolt 5 on the lock body from detaching when the drone is impacted, causing the cabin door to be unable to close.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
