The upper surface of the mounting base plate is fixed with a protective box, and the mounting base plate is fixed on the display platform by fixing bolts. At the same time, the inner part of the protective box is installed with a fixed plate and the upper surface of the fixed plate is installed with a fixed frame. The aircraft model is fixed in the protective box by the fixed frame. At the same time, the top end of the protective box is installed with a cover, the right side of the cover is fixed with a lock, the left bottom end of the lock is opened with an installation slot, and the electric telescopic device is installed through the installation slot, In addition, the front end of the electric telescopic device is fixed with a lock block, which is connected to the power supply of the electric telescopic device through the external power supply. The electric telescopic device drives the lock block to move into the lock hole of the protective box. The lock block can stably fix the cover on the upper end of the protective box to prevent the visitors from opening the cover. During the display process, the protective box can prevent the visitors from directly contacting the aircraft model, and the visitors will not pick up the aircraft model to visit, Avoid unnecessary losses and effectively protect the model aircraft.

固定板底端安装有多个减振器，固定架两侧也均固定有第二减振器，减振器和第二减振器均由液压杆和阻尼减震弹簧组成，在航模飞机运输过程中产生振动力，振动力会通过防护箱传递到航模飞机上，在振动力传第过程中会经过减振器和第二减振器，当振力传递来时液压杆会向下压缩并带动阻尼减震弹簧向下压缩，阻尼减震弹簧向下压缩能有效缓冲传递来的振动力，避免航模飞机受到较大的振动力效果，不会造成航模飞机内部的零件松动，有效保护航模飞机，提高航模飞机的使用寿命。更多相关内容就来我们网站http://www.quanyimoxing.com咨询吧！

Several first shock absorbers are installed at the bottom of the fixed plate, and the second shock absorbers are also fixed on both sides of the fixed frame. The first shock absorber and the second shock absorber are composed of hydraulic rods and damping damping springs, which generate vibration force during the transportation of the aircraft model. The vibration force will be transmitted to the aircraft model through the protective box, and will pass through the first shock absorber and the second shock absorber during the transmission of the vibration force, When the vibration force is transmitted, the hydraulic rod will compress downward and drive the damping spring to compress downward. The downward compression of the damping spring can effectively cushion the transmitted vibration force, avoid the aircraft model being subjected to large vibration force effect, and will not cause the internal parts of the aircraft model to loosen, effectively protect the aircraft model and improve the service life of the aircraft model.
