Description

Technical Field

[0001] The present invention relates to a displacement restraining device for restraining the displacement of an object, and can be used for a container in a cargo hold of an aircraft, for example. Background Art

[0002] When transporting cargo by airplane, it is usually loaded with containers (air containers, pallets, etc.), and then the containers are placed in a preset position in the aircraft cargo hold. The cargo loading system is installed on the floor of the aircraft cargo hold and is used to move the container or limit the movement of the container. The displacement constraint device is used to constrain the displacement of the container and is one of the components of the cargo loading system. According to the requirements of air cargo transportation management, it is necessary to install a displacement constraint device to constrain the displacement of the container in the cargo hold during transportation. The container floor is located at the bottom of the container. After the container is loaded into the cargo hold and reaches the preset position, the displacement constraint device in the cargo hold constrains the container by limiting the displacement of the container floor. When the container needs to be moved (such as loading and unloading cargo), it is necessary to release the displacement constraint of the container floor by the displacement constraint device, and make the displacement constraint device reach a flat state so that the container can move in the cargo hold.

[0003] As prior art, several sets of related displacement restraint devices have been published at home and abroad. For example, "CN202211497494.X / A multifunctional composite guide rail device for aircraft cargo system" applied by Qingan Group Co., Ltd., the lateral guide rail (auxiliary guide rail) involved has the function of automatic reset after the container passes over, but due to its special cantilever structure, the friction force is large when the bottom plate of the container presses down the lateral guide rail, and there is a phenomenon of stuck container in practice, and the device cannot be locked into the displacement restraint state or the restraint release state; "US2018222586A1 / LOCKASSEMBLY WITH ROTATING INNER PAWL" applied by Goodrich Company, the device involved requires hand contact with the rotating claw to operate during use, which is easy to get injured, and the operator needs to be cautious and agile in practice; "US2013121782A1 / SELF-LOCKING, OVERRIDEABLE AND ATTENUATING CARGO GUIDE" applied by Goodrich Company "ANDRESTRAINT", the device involved is of complex structure and large size, and has certain requirements on the floor structure when arranged in the cargo hold; "US2010209209A1 / SELF-LOCKING, OVERRIDEABLE ANDATTENUATING CARGO GUIDE AND RESTRAINT" applied by Goodrich Company, the device involved cannot be flattened, so it is not suitable for extensive arrangement in the cargo hold; "US2008099620A1 / SELF-ADJUSTING ULD LOADINGGUIDE AND RESTRAINT" applied by Goodrich Company, the device involved needs to touch the extension arm and the guide when operating, which is easy to get injured; "US2007086871A1 / AIR CARGO VERTICAL RESTRAINT ASSEMBLY" applied by Goodrich Company, the device involved can only be in a constrained displacement state, which will not facilitate the movement of the container in the cargo hold when loading and unloading the container.

[0071] like Fig.11 As shown, the rotating claw 11 is connected to the operating member 13 via a sliding shaft 23 , and the sliding shaft 23 is installed in a guide groove 101 on the side wall of the base 10 .

[0072] (Action and Function of Displacement Constraint Device 1)

[0073] The following are the main references Figure 1 , Figure 12 to Figure 13 The operation and effect of the displacement restraining device 1 according to the embodiment of the present invention will be described.

[0074] The displacement restraining device 1 according to the embodiment of the present invention can be installed at a preset position of the aircraft cargo hold floor structure according to the specifications of the container, for example.

[0075] like Fig.13 As shown, the displacement constraint device 1 of the embodiment of the present invention is in a flattened state when the displacement constraint is released. At this time, the limiting protrusion 133 on the operating member 13 is located in the flattened position slot 104 of the base 10, and the reset member 24 is in a twisted state.

[0076] like Figure 1 , Fig.12 As shown, when the container is loaded into the cargo hold and reaches the preset position in the cargo hold, the operator hooks the handle 131 on the operating member 13 with his hand and pulls the handle 131 upward to make the limiting protrusion 133 disengage from the flattening position slot 104 of the base 10, and the rotating claw 11 and the supporting member 12 rotate around the follower shaft 22 under the action of the reset member 24. When the rotating claw 11 rotates around the follower shaft 22, it drives the sliding shaft 23 along the guide groove 101, and the sliding shaft 23 drives the operating member 13 to move until the limiting protrusion 133 of the operating member 13 enters the upright position slot 103, and the displacement constraint device 1 reaches the upright state. At this time, Fig.12 As shown, the edge of the container bottom plate 30 is located between the rotating claw 11 of the displacement restraining device 1 and the cargo hold floor plane 40, so as to restrain the displacement of the container bottom plate 30 along the X direction and the Y direction.

[0077] When the container needs to be moved, the handle 131 is first pulled and lifted upward, and the handle 131 is continued to be pulled so that the limit protrusion 133 is located above the flattening position slot 104 of the base 10, and then the handle 131 is pressed down so that the limit protrusion 133 is located in the flattening position slot 104 of the base 10, and the displacement restraint device 1 reaches Fig.13 In the flattened state shown, the displacement constraints of the container bottom plate 30 along the X direction and the Y direction are released.
