Description

Technical Field

[0001] This utility model relates to the field of fixed brackets, and in particular to a foldable and retractable wing fixed bracket. Background Technology

[0002] When disassembling, reassembling, and maintaining existing fighter jets, wing mounting brackets are typically used. These brackets are modular steel structures, usually consisting of an anti-skid load-bearing channel steel, two fixing pins, two load-bearing screws, a load-bearing base frame, and four casters. They are suitable for aircraft with a wing height of 1.23m to 1.73m above the ground and can bear a load of 5 tons. During use, they can support the aircraft fuselage during takeoff and landing. When the aircraft is taken off and the landing gear wheels are off the ground, maintenance personnel can smoothly carry out disassembly, assembly, and maintenance work on the aircraft.

[0003] During use, because the wing mounting bracket is a fixed integrated structure, it occupies the largest storage volume and cannot be compressed, which is extremely detrimental to efficient storage and transportation (especially in hangars or transport vehicles with limited space). Utility Model Content

[0004] In view of the space-consuming problem of integrated brackets in the above or existing technologies, this utility model is proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: A supporting component includes a support body, a fixed frame fixedly connected to the top of the support body, a rotating arm rotatably connected to the top wall of the fixed frame, a pad rotatably connected to the bottom end of the rotating arm, a connecting column rotatably connected to the left side of the pad, a ball joint rotatably connected to the left end of the connecting column, a connecting seat rotatably connected to the left end of the ball joint, and a handle fixedly connected to the top of the connecting seat. A limit assembly is provided inside the support body. An auxiliary moving component includes a fixed rod fixedly connected to the inner side of the right rotating arm, a push arm rotatably connected to the outer side of the fixed rod, and a moving component provided inside the push arm.

[0006] As a preferred embodiment of the foldable and retractable wing fixing bracket of this utility model, the bracket body has a double-section folding structure, and the left and right sides of the bracket body are connected by hinges along the center line.

[0008] As a preferred embodiment of the foldable and retractable wing fixing bracket of this utility model, the limiting component includes a tension rod, which is slidably connected inside the bottom frame of the bracket body. A spring is sleeved on the outside of the tension rod, and a bending plate is fixedly connected to the back of the tension rod. A limiting post and an arc block are fixedly connected to the back of the bending plate.

[0009] As a preferred embodiment of the foldable and retractable wing fixing bracket of this utility model, the left rotating arm has an insertion hole corresponding to the limiting post inside, there are two limiting posts, and the protruding edges are rounded.

[0010] As a preferred embodiment of the foldable and retractable wing fixing bracket of this utility model, the movable component includes a receiving plate, which is rotatably connected to the top of the push arm, and a push rod is fixedly connected to the bottom of the receiving plate, with a moving wheel fixedly connected to the bottom of the push rod.

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a foldable and retractable wing fixing bracket, which can achieve the effect of reinforcing and supporting the bracket body 10 before and after folding. It includes a support component, including a bracket body 10. A fixing frame 11 is fixedly connected to the top of the bracket body 10. A rotating arm 12 is rotatably connected to the top wall of the fixing frame 11. A pad 13 is rotatably connected to the bottom end of the rotating arm 12. A connecting post 14 is rotatably connected to the left side of the pad 13. A ball head post 15 is rotatably connected to the left end of the connecting post 14. A connecting seat 16 is rotatably connected to the left end of the ball head post 15. A handle 17 is fixedly connected to the top of the connecting seat 16. A limit component 18 is provided inside the bracket body 10.

[0023] Specifically, through the set connection and transmission structure, the pad 13 can be placed at the lowest point before and after the bracket body 10 is folded, so that it is in contact with the ground. When the bracket body 10 is in use, the pad 13 can reinforce and support its center. When folding, the pad 13 can prevent the folded bracket body 10 from tilting forward, and can also provide long-term support during storage.

[0024] Furthermore, the support body 10 has a double-section folding structure, and the left and right sides of the support body 10 are connected by hinges along the center line. The bottom frame of the support body 10 is provided with a support frame that matches the handle 17, and the handle 17 reciprocates around the center column of the support frame.

[0025] The bracket body 10 adopts a two-section folding structure and can be folded and rotated together along the center. During storage and transportation, the rotation is not limited by the length of the hangar or transport vehicle. With the pad 13 that can move up and down and fit against the ground, the stability during use is improved. The support frame can provide a limiting support for the handle 17, so that it can stably drive the connecting seat 16 to rotate, thereby adjusting the height of the pad 13 from the ground.

[0026] Through the linkage transmission structure composed of connecting column 14, ball head column 15 and connecting seat 16, the bottom of the pad 13 can be in contact with the ground when the grip handle of the handle 17 is rotated to the highest position, and the pad 13 moves to the highest position when the grip handle of the handle 17 is rotated to the lowest position.

[0027] Preferably, the limiting component 18 includes a tension rod 181, which is slidably connected inside the bottom frame of the bracket body 10. A spring 182 is sleeved on the outside of the tension rod 181. A bending plate 183 is fixedly connected to the back of the tension rod 181. A limiting post 184 and an arc block 185 are fixedly connected to the back of the bending plate 183. An insertion hole corresponding to the limiting post 184 is opened inside the left rotating arm 12. There are two limiting posts 184, and the protruding edges are rounded.

[0028] It should be noted that since only one insertion hole is provided inside the rotating arm 12, and the insertion hole changes its position as the rotating arm 12 rotates, when the handle 17 is moved to the highest and lowest position, the position of the insertion hole before and after the change can correspond to the two limiting posts 184, thereby limiting the position of the pad 13. At the same time, by utilizing the rounded corner structure of the limiting post 184, in conjunction with the support of the arc block 185, positioning and fixing can be avoided. When the limiting post 184 is pulled out, it moves to the corresponding hole position, which can achieve automatic fixing.

[0029] When in use, since the initial state of the bracket body 10 is folded and in a stowed state, the bottom of the pad 13 is in contact with the ground to provide support. First, turn the handle 17 to make the handle 17 drive the connecting seat 16 to rotate. When the grip handle of the handle 17 is rotated to the lowest position, the tilt angle of the ball head 15 increases through the rotational connection between the connecting column 14, the ball head 15 and the connecting seat 16. At this time, the connecting seat 16 is placed at the highest position. At this time, the pad 13 will be placed at the highest position through the pulling of the connecting column 14 and the rotational connection of the rotating arm 12. At this time, the folded bracket body 10 can be moved to the designated position.

[0030] Before rotating the handle 17, the tension rod 181 needs to be pulled first, so that the spring 182 drives the limiting post 184 away from the insertion hole of the left rotating arm 12. When the handle 17 is turned, since the position of the limiting post 184 does not correspond to the position of the insertion hole, the tension rod 181 can be released. With the support of the arc block 185 and the rounded corner of the limiting post 184, when the handle 17 is turned, after the position of the other limiting post 184 corresponds to the position of the insertion hole, the limiting post 184 will directly insert into the insertion hole to limit the rotating arm 12. There is no need to manually position and fix the calibration by pulling the tension rod 181 for a long time.

[0031] When the support body 10 moves to the support position, the above operation can be repeated. First, unlock the rotating arm 12 and rotate the handle 17 so that the grip handle is rotated to the highest point, so that the bottom of the pad 13 can be in contact with the ground, thus providing stable support for the support body 10. At this time, rotate the support body 10 to unfold it from the folded state.

[0032] It should be noted that the bracket body 10 itself serves as a support structure for folding and unfolding. Before and after unfolding, its state needs to be fixed. Spring clips can be welded and installed, or holes can be drilled and rods can be used for limiting. Both methods can achieve the fixation of the folded and unfolded states.

[0033] Example 2, refer to Figure 5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an auxiliary moving component for a foldable and retractable wing fixing bracket based on embodiment 1. This solves the problem that the bracket body 10 cannot move normally in the folded state after the pad 13 stops supporting it. The auxiliary moving component includes a fixing rod 20, which is fixedly connected to the inner side of the right rotating arm 12. A push arm 21 is rotatably connected to the outside of the fixing rod 20. A moving component 22 is provided on the inner side of the push arm 21. The moving component 22 includes a receiving plate 221, which is rotatably connected to the top of the push arm 21. A push rod 222 is fixedly connected to the bottom of the receiving plate 221. A moving wheel 223 is fixedly connected to the bottom of the push rod 222. There are two push arms 21, and the two push arms 21 are symmetrically distributed at the bottom of the receiving plate 221.

[0034] Specifically, after the support body 10 is folded and the pad 13 is raised, the moving wheel 223 can be lowered through the connection structure of the two push arms 21, so as to support the side of the support body 10 without the universal wheel and ensure that it can move and transfer stably.

[0035] When in use, when the pad 13 rises, it will cause the fixing rod 20 to change position. Because the fixing rod 20 changes position, the push arm 21 will bend, causing the receiving plate 221 to move downward. When the receiving plate 221 moves downward, it will push the push rod 222 downward, so that the moving wheel 223 contacts the ground, which can support the transferred folded bracket body 10 and enable it to move to the storage position.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
