Description

Technical Field

[0001] This utility model belongs to the field of aviation mechanical structure technology, and in particular relates to a miniaturized chassis lifting device. Background Technology

[0002] When airborne equipment is installed on an aircraft, its data transmission socket is located at the tail end because it needs to couple with the aircraft's electrical connectors. These connectors transmit very high amounts of data, resulting in very high coupling forces between the connector plug and socket. This high coupling force severely affects the installation and removal of airborne equipment during routine use. Therefore, a lifting device is needed to assist the airborne equipment in overcoming this coupling force, thereby enabling its installation and removal on the aircraft. Utility Model Content

[0003] To address the problems in the background art, this utility model provides a miniaturized chassis lifting and unloading device that can assist airborne equipment in overcoming the high coupling force of electrical connectors, smoothly achieving reliable electrical connector docking, while locking the airborne equipment on the mounting bracket, and also enabling smooth removal of the airborne equipment from the equipment rack.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0010] Furthermore, the latch 5 is elongated, with one end being a flat cylinder connected to the movable hook 4, and the other end being an L-shaped configuration with arranged grooves on the L-shape. The groove surface is used for manually unlocking the pull-out device.

[0011] Furthermore, the grip shaft 6 is a long cylindrical structure and is connected to the main frame 1 by an interference fit.

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] See Figure 1 and Figure 2 The chassis lifting device of this utility model includes: a main frame 1, a sliding cavity 2, a power spring 3, a movable hook 4, a locking buckle 5, and a gripping shaft 6;

[0024] like Figure 3 As shown, the main frame 1 is rectangular, with a notch at one end for fastening with the positioning shaft on the bracket. Two connecting holes are located next to the notch for securing the main frame 1 to the chassis. Connecting holes are located in the upper middle section for connecting parts 2-5. The other end is semi-circular with a through-hole for connecting the grip shaft 6.

[0025] like Figure 4 As shown, the middle part of the sliding cavity 2 is rectangular, with a cylindrical hole embedded inside. A movable hook 4 is embedded in the hole. The rectangle has square edges on both sides, and through holes are opened on the square edges for connecting with the main frame 1.

[0026] like Figure 5 As shown, the power spring 3 has a ring-shaped structure and is a compression spring as a whole, with the parts fitted onto the movable hook 4;

[0027] like Figure 6 As shown, the movable hook 4 is a cylindrical structure with one end being a long cylinder that fits into one end of the sliding cavity 2, and the other end being a sloping surface that engages with the parts on the upper panel of the chassis. It can lock the lifting device and has a waist-shaped hole in the middle, which is connected to the buckle 5 by riveting.

[0028] like Figure 7 As shown, the latch 5 is a long strip, with one end being a flat cylinder connected to the movable hook 4, and the other end being an L-shaped structure with arranged grooves on the L-shape. The groove surface is used for manually unlocking the pull-out device.

[0029] like Figure 8 As shown, the grip shaft 6 is a long cylindrical structure and is connected to the main frame 1 by an interference fit.

[0030] The chassis lifting device is fixedly connected to the airborne equipment panel via two round holes next to the notch at the lower end of the main frame 1. When the chassis lifting device is in operation, it engages the notch at the lower end of the main frame 1 with the fixed shaft at the front end of the mounting bracket, and then the grip shaft 6 is manually pushed. At this time, the chassis lifting device will slowly move the airborne equipment into the mounting bracket, during which the electrical connector will gradually couple. When the electrical connector is finally coupled into place, it indicates that the airborne equipment is installed correctly, and the movable hook 4 in the chassis lifting device will automatically lock.

[0031] When it is necessary to remove the airborne equipment from the mounting bracket, manually push the latch 5. The latch 5 will unlock the movable hook 4 from the airborne equipment. Then pull the grip shaft 6 away from the airborne equipment. At the same time, the electrical connector of the airborne equipment will be separated. Continue to pull the grip shaft 6 until the airborne equipment is completely separated from the mounting bracket, and the equipment can be removed from the machine.

[0032] This utility model provides a miniaturized chassis lifting device, (1) which can effectively overcome the high coupling force of electrical connectors; (2) which can assist in the reliable connection between airborne equipment and equipment mounting frame, and the lifting device has self-locking capability; (3) when airborne equipment needs to be disassembled from the machine, the lifting device can smoothly separate the equipment from the mounting frame; (4) the lifting device is lightweight and thin, can be closely attached to the panel, and the device occupies little space.
