Description

Technical Field

[0001] This utility model relates to the field of Fod cleaning blanket technology, specifically a Fod cleaning blanket that is easy to connect to a tractor. Background Technology

[0002] Airport runways are dedicated areas for aircraft takeoff and landing, and are one of the core facilities of an airport. The design, length, width, and materials of the runway directly affect the takeoff and landing performance of aircraft and the operational capacity of the airport. Fod cleaning mats are commonly used during runway cleaning to prevent screws, metal fragments, stones, and other debris from being sucked into aircraft engines, ensuring normal aircraft operation.

[0003] The patent application CN220057761U, entitled "A FOD Cleaning Mat Towing Device," describes a cleaning mat being fixed by connecting the mounting base 1 to the rear of the tractor via a pin, as shown in the accompanying drawings. Similarly, patent application CN211270519U, entitled "A Connection Structure Between a Cleaning Mat and a Vehicle," mentions that "the connecting sleeve 234 is fitted onto the traction end of the tractor." This fitting connection typically uses a sleeve (or tube) and a connecting rod (or shaft). Over time, dust and impurities accumulate on the shaft, increasing friction and making disassembly of the cleaning mat extremely difficult. Furthermore, during installation, the cleaning mat's position must be adjusted multiple times to align the pin hole on the mounting base 1 with the connection hole at the rear of the tractor for easy pin insertion.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a Fod cleaning mat that is easy to connect to a tractor, including a cleaning mat body 1 and a traction plate 2 connected to the cleaning mat body 1. A connector 3 is connected to the end of the traction plate 2, and a rod 17 is connected to the inner side of the connector 3. The rod 17 matches a connecting post 6 connected to the inner side of the mounting base 5. The connecting post 6 is connected to a positioning mechanism for positioning the rod 17. The positioning mechanism includes a spring 7, a moving cylinder 4, and multiple locking balls 16. Typically, four locking balls 16 are provided, with adjacent balls forming a 90° angle. The moving cylinder 4 is movably connected to the connecting post 6, and the spring 7 drives the moving cylinder 4 to move closer to the connector 3. The locking balls 16 are movably connected to the connecting post 6 and match a locking groove 18 located on the outer side of the rod 17. The inner side of the moving cylinder 4 is connected to the locking balls 16, and the moving cylinder 4 is connected to a drive mechanism for reciprocating movement.

[0021] During the installation of the cleaning mat body 1, the insertion rod 17 is inserted into the connecting post 6, and then the rotating rod 10 is loosened. The compressed spring 7 pushes the moving cylinder 4 forward, causing the inclined surface 19 to slide relative to the locking ball 16, which in turn pushes the locking ball 16 to move towards the corresponding locking groove 18. When the moving cylinder 4 stops moving, its end connects to the connecting head 3, its inner surface connects to the locking ball 16, and the locking ball 16 connects to the locking groove 18, thus locking and fixing the insertion rod 17, improving the stability of the cleaning mat body 1 installation, and increasing efficiency.

[0022] When the main body 1 of the cleaning mat is in the positioning state, the spring 7 is still in the compressed state.

[0023] The positioning mechanism also includes multiple guide grooves 9 and inclined surfaces 19. The guide grooves 9 are used to guide the moving cylinder 4, and the inclined surfaces 19 are located at the end of the moving cylinder 4. The inclined surfaces 19 are smooth surfaces, which can reduce the contact friction with the locking ball 16.

[0024] The guide groove 9 is located on the outside of the connecting column 6, and the moving cylinder 4 is slidably connected to the guide groove 9, which improves the stability of the reciprocating movement of the moving cylinder 4 and plays a good guiding role.

[0025] Spring 7 is fitted onto connecting post 6, and both ends of spring 7 are connected to mounting base 5 and movable cylinder 4.

[0026] The connecting column 6 is provided with multiple movable cavities 20. The locking ball 16 is connected to the movable cavity 20. There are usually four movable cavities 20, with an adjacent included angle of 90°. The locking ball 16 can move within the movable cavity 20, but cannot be removed from the movable cavity 20.

[0027] The drive mechanism includes a pull rod 8, a rotating rod 10, a handle 11, a limiting plate 13, and a positioning bolt 14. Both ends of the pull rod 8 are connected to the rotating rod 10 and the moving cylinder 4 via shafts. One end of the rotating rod 10 is connected to the mounting base 5, and the other end is connected to the handle 11. The limiting plate 13 is connected to the mounting base 5 and matches the rotating rod 10. The positioning bolt 14 is used to position the rotating rod 10. When disassembling the cleaning mat body 1, the insert rod 17 needs to be loosened. Pushing the handle 11 causes the rotating rod 10 to rotate, which applies a pulling force to the pull rod 8. The pull rod 8 pulls the moving cylinder 4 backward, compressing the spring 7. Until the rotating rod 10 connects to the limiting plate 13, the inner side of the moving cylinder 4 separates synchronously from the four locking balls 16. Then, the positioning bolt 14 is used to lock and fix the rotating rod 10. At this time, the insert rod 17 is in a loosened state. The insert rod 17 is then pulled out of the slot 15, facilitating the disassembly of the cleaning mat body 1 with high efficiency.

[0028] The rotating rod 10 has a positioning groove 12 on its side, which matches the end of the positioning bolt 14. The positioning bolt 14 is threadedly connected to the limiting plate 13. Rotating the positioning bolt 14 so that its end is inserted into the positioning groove 12 can lock and fix the rotating rod 10, thereby facilitating the limiting of the moving cylinder 4 and making it easy to insert the insertion rod 17 into the slot 15.

[0029] The connecting post 6 is provided with a slot 15, and the insert rod 17 is connected to the slot 15. When the insert rod 17 is inserted into the slot 15 and the insert rod 17 cannot be moved, the locking groove 18 is aligned with the corresponding locking ball 16, which facilitates the subsequent docking of the two.

[0030] Working principle: In use, insert the insertion rod 17 into the slot 15 of the connecting post 6 until the insertion rod 17 stops moving, at which point the locking ball 16 aligns with the locking groove 18. Loosening the positioning bolt 14 releases the rotating rod 10, and the compressed spring 7 pushes the moving cylinder 4 forward. The inclined surface 19 slides relative to the locking ball 16, driving the locking ball 16 to move towards the corresponding locking groove 18. Until the end of the moving cylinder 4 connects with the connecting head 3, the inner side of the moving cylinder 4 connects with the locking ball 16, and the locking ball 16 connects with the locking groove 18, thus locking and fixing the insertion rod 17 and improving the stability of the cleaning blanket body 1 during installation. When the main body of the sweeping mat 1 needs to be disassembled, hold the handle 11 and drive the rotating rod 10 to rotate. The rotating rod 10 applies a pulling force to the pull rod 8, which can pull the moving cylinder 4 backward. The spring 7 is compressed until the rotating rod 10 is connected to the limiting plate 13. The moving cylinder 4 and the four locking balls 16 are separated synchronously, thereby loosening the insertion rod 17. Then pull the insertion rod 17 to separate it from the slot 15, which facilitates the disassembly of the main body of the sweeping mat 1. The operation is simple, convenient and efficient.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
