The left end of the clamping block is fixed to the landing gear, and the outer side thereof is clamped to the support seat.

[0013] As a further solution of the utility model, the clamping plate can be clamped with the clamping area after being rotated upward, wherein the rotation intersection of the rotating rod and the support rod is below the center of the support rod, so that when the rotating rod and the second landing gear rotate, the clamping plate rotates about this point, thereby gradually reducing the distance from the clamping area during rotation, and when rotating to obliquely above the clamping area, it is necessary to use a little force to pry the second landing gear so that the clamping plate is clamped into the top of the clamping area to achieve clamping, thereby fixing the deployment of the second landing gear.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to further explain the technical solution of the present utility model, it will be elaborated in detail below through specific embodiments.

[0030] Please refer to Figures 1-7 In the embodiments of the present utility model:

[0031] A landing gear recovery device for an airplane model comprises a model body 1, a front end recovery slot 2, a recovery plate 3, an auxiliary block 4, a clamping piece 5, a landing gear 6, a force application block 7, a middle recovery slot 8, a large recovery plate 9, a second auxiliary block 10, a small recovery plate 11, a second clamping piece 12, a rotating rod 13, a second landing gear 14, and a second force application block 15; a front end recovery slot 2 is provided at the front end of the model body 1, and a middle recovery slot 8 is provided in the middle thereof; the recovery plate 3 is hinged to the model body 1, and the recovery plate 3 is located at the front end The front end of the recovery groove 2; the clamping member 5 is fixed to the inside of the front end recovery groove 2, and the inner side thereof is rotatably connected to the landing gear 6 through a torsion spring, and a force block 7 is fixed to the front end of the landing gear 6; the large recovery plate 9 and the small recovery plate 11 are respectively hinged to the model body 1, and they are both located at the front end of the middle recovery groove 8; the right end of the second clamping member 12 is fixed to the model body 1, and the left end thereof is rotatably connected to the rotating rod 13, the upper end of the second landing gear 14 is fixed to the rotating rod 13, and a second force block 15 is fixed to the front end thereof.

[0032] In this embodiment, the second clamping member 12 includes a support rod 121, a clamping area 122, and a clamping plate 123. The right end of the support rod 121 is fixed to the model body 1, and the left end thereof is rotatably connected to the second clamping member 13. The left end of the support rod 121 is provided with a clamping area 122, and the lower end of the clamping plate 123 is fixed to the second landing gear 14.

[0033] In this embodiment, the clamping member 5 includes a support seat 51 and a clamping block 52. The support seat 51 is fixed inside the front end recovery slot 2, and its inner side is rotatably connected to the landing gear 6 through a torsion spring. The left end of the clamping block 52 is fixed to the landing gear 6, and its outer side is clamped to the support seat 51.

[0034] In this embodiment, the clamping plate 123 can be clamped with the clamping area 122 after rotating upward, wherein the rotation intersection of the rotating rod 13 and the support rod 121 is below the center of the support rod 121, so that when the rotating rod 13 and the second landing gear 14 rotate, the clamping plate 123 rotates about this point, thereby gradually reducing the distance from the clamping area 122 during rotation, and when rotating to the oblique upper part of the clamping area 122, it is necessary to use a little force to pry the second landing gear 14 so that the clamping plate 123 is clamped into the upper part of the clamping area 122 to achieve clamping, thereby fixing the deployment of the second landing gear 14.

[0035] In this embodiment, an auxiliary block 4 is provided at the upper end of the recovery plate 3, which is convenient for flipping the recovery plate 3 through the auxiliary block 4, so as to unfold the landing gear 6 placed inside. The auxiliary block 4 plays a role in facilitating the application of force. The cross section of the front end recovery groove 2 is "convex", which is convenient for adapting to the "T" shape after the landing gear 6 is placed, so as to achieve the simplified control of the size of the front end recovery groove 2, so that the overall structure is simple and efficient. A second auxiliary block 10 is fixed to the upper end of the large recovery plate 9, which is convenient for flipping the large recovery plate 9 through the second auxiliary block 10 to expose the internal middle recovery groove 8, thereby providing a force point for the flipping of the small recovery plate 11. The placement and deployment of the landing gear are achieved by rotating the landing gear left and right. When the landing gear rotates, the clamping block 52 and The support seat 51 is slightly staggered and clamped, so that when the clamping block 52 rotates to the left or right, the landing gear 6 needs to be pried with a little force due to the clamping with the support seat 51 to be stably deployed or retracted, thereby achieving the stability of the landing gear 6 after deployment. The placement and deployment of the second landing gear 14 are achieved by the up and down rotation of the second landing gear 14 and the second clamping member 12. When the second landing gear 14 rotates, the center point of its rotation deviates from the center point of the support rod 121, so that when the second landing gear 14 rotates, the distance between the second landing gear 14, the clamping plate 123 and the support rod 121 gradually decreases, which facilitates the clamping of the clamping plate 123 and the clamping area 122, thereby achieving the stability of the second landing gear 14 after deployment.

[0036] refer to Figures 1-4 When the landing gear 6 is deployed, the auxiliary block 4 is used to position and apply force, and the recovery plate 3 is turned outward to expose the internal landing gear 6, and the landing gear 6 is turned over with the help of the force-applying block 7. When turning over, the clamping block 52 and the support seat 51 are slightly staggered and clamped, so that when the clamping block 52 is rotated to the left, it is necessary to use a little force to bend the landing gear to deploy it due to the clamping connection with the support seat 51, and the elastic force of the torsion spring is used to stably deploy the landing gear 6, and the landing gear 6 is not easy to rotate due to the slight clamping, so as to achieve the purpose of positioning and stable deployment;

[0037] When the second landing gear 14 is deployed, the second auxiliary block 10 is used to position and apply force, and the large recovery plate 9 is turned over, and then the small recovery plate 11 is turned over to completely expose the second landing gear 14 inside, and then the second force-applying block 15 is used to rotate the second landing gear 14 and the rotating rod 13. Because the rotation intersection of the rotating rod 13 and the supporting rod 121 is below the center of the supporting rod 121, when the rotating rod 13 and the second landing gear 14 are rotated, the clamping plate 123 rotates about this point, so that the distance from the clamping area 122 is gradually reduced during the rotation, and when the second landing gear 14 is rotated to the oblique upper part of the clamping area 122, it is necessary to slightly force the second landing gear 14 to make the clamping plate 123 clamped to the top of the clamping area 122 to achieve clamping, thereby fixing the deployment of the second landing gear 14;

[0038] When it is necessary to retract the landing gear 6 and the second landing gear 14, first reset the landing gear 6 and the second landing gear 14 inside the front retraction groove 2 and the middle retraction groove 8 respectively, and then flip the retraction plate 3, the large retraction plate 9 and the small retraction plate 11 to achieve complete retraction.

[0039] The control mode of the present utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art, and the present utility model is mainly used to protect mechanical devices. Therefore, the control mode and wiring layout of the present utility model will not be explained in detail.

The control circuit of the controller can be realized by simple programming by those skilled in the art, and the power supply is also common knowledge in the art. Moreover, the present utility model is mainly used to protect mechanical devices. Therefore, the control mode and circuit connection of the present utility model will not be explained in detail.

[0041] The above are only the preferred examples of the present utility model and are not used to limit the present utility model.
