Description

Technical Field

[0001] This utility model relates to the field of target technology, specifically a helicopter target. Background Technology

[0002] Helicopter targets play a crucial role in military training, weapons testing, and aerospace research. They can simulate the flight characteristics and target features of real helicopters, providing important reference data for the development of various weapon systems, effectiveness evaluation, and training of military personnel.

[0003] In existing technologies, traditional helicopter targets employ a cross-shaped anti-tipping design when no civil engineering base is available. In practical applications, the target height often needs to be flexibly adjusted according to specific site requirements due to different training or testing needs. When the target height is high, the fixed support base based on the cross structure has a relatively fixed and limited support area. As the target height increases, the overall center of gravity of the target also rises. In severe weather, the torque acting on the target will increase significantly under the influence of external factors such as wind and airflow disturbances. The limited support area cannot provide sufficient anti-tipping torque to balance this change, thus drastically increasing the risk of the support base tipping over. This tipping phenomenon will not only cause serious damage to the target itself, affecting its normal use and service life, but may also threaten the safety of surrounding training facilities and personnel. Furthermore, reinstallation and adjustment after the target tipps over will consume a lot of manpower, material resources, and time, seriously reducing the efficiency and continuity of training or testing. Therefore, there is an urgent need for a helicopter target to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a helicopter target that solves the problem mentioned in the background art of traditional helicopter targets that are difficult to adjust the support area of ​​the support base according to the wind intensity in severe weather.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a helicopter target, including a support base, wherein a pre-embedded seat is fixedly connected to the bottom surface of the support base, an adjustment component is provided on the bottom surface of the support base, and a linkage component is provided on the bottom surface of the support base;

[0006] The adjusting assembly includes a rotating column rotatably connected to the inner wall of a support base. A spur gear is fixedly connected to the surface of the rotating column. Multiple fixed tubes are provided on the bottom surface of the support base. A rack is slidably connected to the inner wall of each fixed tube. A connecting block is fixedly connected to the bottom surface of the rack. A threaded column is fixedly connected to the bottom surface of the connecting block. A fixed frame is fixedly connected to the lower end of the threaded column. A rotating wheel is rotatably connected to the inner wall of the fixed frame. The tooth pitch of the spur gear matches the tooth pitch of the rack. The surface of the spur gear meshes with the side wall of the rack. A connecting tube is rotatably connected to the top surface of the rack. A telescopic rod is rotatably connected to the top surface of the support base. The telescopic rod is slidably connected to the inner wall of the connecting tube. A compression spring is fixedly connected to the inner wall of the connecting tube. The upper end of the compression spring abuts against the bottom surface of the telescopic rod.

[0007] In this technical solution, the adjustment components allow the rotating column to rotate, which in turn drives the spur gear to rotate. The rotation of the spur gear then drives multiple racks to move simultaneously, which in turn drives multiple fixed frames to move simultaneously. This allows for adjustment of the appropriate support area based on the wind strength at the site, thereby making the target more stable during use.

[0008] Preferably, the linkage component includes a fixed plate, which is fixedly connected to the side wall of the support base. A rotating column is rotatably connected to the inner wall of the fixed plate. A rotating block is fixedly connected to the upper end of the rotating column. Synchronous pulleys are fixedly connected to the surfaces of the rotating column and the rotating column, and the same belt is sleeved on the surfaces of the two synchronous pulleys.

[0009] In this technical solution, the linkage component enables the rotating block to rotate by means of a belt and a synchronous pulley, thereby driving the rotating column to rotate. This facilitates the adjustment of the support area of ​​the support base and improves the adjustment efficiency.

[0010] Preferably, the surface of the fixing frame is threadedly connected to a threaded bracket, and the bottom surface of the threaded bracket is fixedly connected to a fixing block.

[0011] In this technical solution, by setting a fixed block, after the support area is adjusted, rotating the threaded frame will cause the fixed block to descend and make close contact with the ground, thereby improving the stability of the support.

[0012] Preferably, the bottom surface of the support base is fixedly connected to a plurality of I-beams, the top surfaces of the two upper fixed tubes are fixedly connected to the bottom surface of the support base, and the top surfaces of the two lower fixed tubes are fixedly connected to the bottom surface of the I-beams.

[0013] In this technical solution, the I-beams facilitate the offsetting of the two lower fixed tubes from the two upper fixed tubes, allowing multiple racks to mesh with the spur gears simultaneously. Furthermore, the I-beams also facilitate the fixing of the two lower fixed tubes to the bottom surface of the support base.

[0014] Preferably, the inner wall of the fixing block is fixedly connected with an anti-slip pad, which is made of rubber.

[0015] In this technical solution, the use of rubber anti-slip mats increases the friction between the anti-slip mats and the ground.

[0016] Preferably, the bottom of the support base is fixedly connected to a protective box, and the surface of the rotating column is rotatably connected to the inner wall of the protective box.

[0017] In this technical solution, the protective box facilitates the protection of the belt and timing pulley, preventing workers from touching the belt and timing pulley during operation.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The adjustable components allow the rotating column to rotate, which in turn drives the spur gear. The rotation of the spur gear then drives multiple racks to move simultaneously, which in turn drives multiple fixed frames to move simultaneously. This allows for easy adjustment of the support area based on the wind strength at the site, thus ensuring greater stability of the target during use. The linkage components allow the rotating block to rotate via a belt and a synchronous pulley, which in turn drives the rotating column to rotate. This facilitates adjustment of the support area of ​​the support base, improving adjustment efficiency. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-6This utility model provides a helicopter target, including a support base 1, with a pre-embedded seat 4 fixedly connected to the bottom surface of the support base 1. An adjustment component 2 and a linkage component 3 are also provided on the bottom surface of the support base 1. The adjustment component 2 includes a rotating column 201 rotatably connected to the inner wall of the support base 1. A spur gear 202 is fixedly connected to the surface of the rotating column 201. Multiple fixing tubes 203 are provided on the bottom surface of the support base 1, and racks 204 are slidably connected to the inner walls of the fixing tubes 203. The bottom of the racks 204... A connecting block 205 is fixedly connected to the top surface of the support base 1. A threaded post 206 is fixedly connected to the bottom surface of the connecting block 205. A fixing frame 207 is fixedly connected to the lower end of the threaded post 206. A rotating wheel 208 is rotatably connected to the inner wall of the fixing frame 207. The pitch of the spur gear 202 matches the pitch of the rack 204. The surface of the spur gear 202 meshes with the side wall of the rack 204. A connecting pipe 213 is rotatably connected to the top surface of the rack 204. A telescopic rod 214 is rotatably connected to the top surface of the support base 1. The telescopic rod 214 and the connecting pipe 213 are connected to each other. The inner wall of the connecting pipe 213 is slidably connected, and a compression spring 215 is fixedly connected to the inner wall of the connecting pipe 213. The upper end of the compression spring 215 abuts against the bottom surface of the telescopic rod 214. After the pre-embedded seat 4 is pre-embedded, the support seat 1 is fixed to the pre-embedded seat 4. The rotating column 201 is rotated by the adjusting component 2, which drives the spur gear 202 to rotate. The rotation of the spur gear 202 drives multiple racks 204 to move simultaneously. The movement of the racks 204 causes the racks 204, connecting pipe 213, and telescopic rod to move simultaneously. The increased inclination of the triangle formed between 214 and support base 1 allows multiple racks 204 to move simultaneously, which in turn drives multiple fixed frames 207 to move simultaneously. This facilitates the adjustment of the appropriate support area according to the wind intensity on site, making the target more stable during use and preventing the support base from tipping over when the wind is strong. The rotating wheel 208 ensures that the support base 1 is fixed to the pre-embedded base 4 while the rotating wheel 208 is in contact with the ground, thus facilitating the movement of racks 204 when rotating the rotating column 201.

[0029] Furthermore, the linkage component 3 includes a fixed plate 301, which is fixedly connected to the side wall of the support base 1. A rotating column 302 is rotatably connected to the inner wall of the fixed plate 301. A rotating block 303 is fixedly connected to the upper end of the rotating column 302. Synchronous wheels 304 are fixedly connected to the surfaces of the rotating column 302 and the rotating column 201. The same belt 305 is sleeved on the surfaces of the two synchronous wheels 304. Through the linkage component 3, the rotating block 303 is rotated by the cooperation of the belt 305 and the synchronous wheel 304, thereby driving the rotating column 201 to rotate. This facilitates the adjustment of the support area of ​​the support base and improves the adjustment efficiency.

[0030] Furthermore, the surface of the fixed frame 207 is threadedly connected to a threaded frame 209, and the bottom surface of the threaded frame 209 is fixedly connected to a fixing block 210. With the fixing block 210, after the support area is adjusted, rotating the threaded frame 209 will cause the fixing block 210 to descend and make close contact with the ground, thereby improving the stability of the support.

[0031] Furthermore, multiple I-beams 212 are fixedly connected to the bottom surface of the support base 1. The top surfaces of the two upper fixed tubes 203 are fixedly connected to the bottom surface of the support base 1, and the top surfaces of the two lower fixed tubes 203 are fixedly connected to the bottom surface of the I-beams 212. The I-beams 212 facilitate the offsetting of the two lower fixed tubes 203 from the two upper fixed tubes 203, thereby allowing multiple racks 204 to mesh with the spur gear 202 simultaneously. At the same time, the multiple I-beams 212 facilitate the fixing of the two lower fixed tubes 203 to the bottom surface of the support base 1.

[0032] Furthermore, an anti-slip pad 211 is fixedly connected to the inner wall of the fixing block 210. The anti-slip pad 211 is made of rubber. The rubber anti-slip pad 211 makes it easier to increase the friction between the anti-slip pad 211 and the ground.

[0033] Furthermore, a protective box 306 is fixedly connected to the bottom of the support base 1, and the surface of the rotating column 201 is rotatably connected to the inner wall of the protective box 306. The protective box 306 facilitates the protection of the belt 305 and the synchronous pulley 304, preventing workers from touching the belt 305 and the synchronous pulley 304 during operation.

[0034] Working principle: In use, after the pre-embedded seat 4 is pre-embedded, the support base 1 is fixed to the pre-embedded seat 4. Through the setting adjustment component 2, the rotation of the rotating column 201 drives the spur gear 202 to rotate. The rotation of the spur gear 202 drives multiple racks 204 to move simultaneously. The movement of the racks 204 increases the inclination degree of the triangle formed between the racks 204, connecting pipe 213, telescopic rod 214 and support base 1. The simultaneous movement of multiple racks 204 drives multiple fixing frames 207 to move simultaneously, thereby facilitating the adjustment of the appropriate support area according to the wind strength on site. This makes the target more stable during use and prevents the support base from tipping over when the wind is strong. Through the setting linkage component 3, the rotating block 303 drives the rotating column 201 to rotate through the cooperation of the belt 305 and the synchronous pulley 304, thereby facilitating the adjustment of the support area of ​​the support base and improving the adjustment efficiency.
