Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Example:
[0027] See also Figure 1-7 , a shockproof screw air compressor for producing ductile iron manhole covers, comprising a screw air compressor body 1 and an elastic support component.
[0028] The elastic support assembly includes a support plate 2, a spring 4, a support shaft 5 and a limiting wheel 7. The support plate 2 is connected to the bottom of the screw air compressor body 1, and the spring 4 is sleeved inside the support shaft 5. Each support shaft 5 passes through the support plate 2. The support shaft 5 is in the shape of a T-shaped shaft. The support shaft 5 is connected to the limiting wheel 7 by a thread. The support plate 2 is located between the limiting wheel 7 and the spring 4. The limiting wheel 7 is preferably in the shape of a tubular object with a hand wheel on the outer edge and a threaded fixed middle part. The distribution of the support shafts 5 is preferably one in the middle of the support plate 2 and multiple ones are arranged at the edge of the support plate 2. The screw air compressor body 1 is composed of a screw pump and a storage tank for temporary storage medium, which is a common device of existing screw air compressors. , through the cooperation between the limiting wheel 7 and the support shaft 5, when the shock absorbing effect needs to be adjusted, the limiting wheel 7 is rotated, and the limiting wheel 7 and the support shaft 5 cooperate to drive the spring 4 to compress, and adjust the position between the support plate 2 and the support shaft 5. After the spring 4 is compressed, it changes into different elastic forces, and then adjusts the elastic forces supporting the screw air compressor body 1 and the support plate 2, thereby improving the shock absorbing effect on the screw air compressor body 1 and the support plate 2. By rotating the limiting wheel 7, it is more convenient to adjust the elastic forces of each support shaft 5, improve the supporting effect of adjusting the elastic forces at the support shaft 5, adapt to more application environments, reduce the amplitude of vibration, and reduce damage to the screw air compressor body 1.
[0029] Reference Figure 3 and 5 The elastic support component also includes a sleeve 1 3 and a sleeve 2 9, the sleeve 2 9 is sleeved on the sleeve 1 3, the spring 4 and the support shaft 5 are located inside the sleeve 1 3 and the sleeve 2 9, the protrusion of the support shaft 5 corresponds to the inner wall of the sleeve 1 3, and through the arrangement of the sleeve 1 3 and the sleeve 2 9, the spring 4 and the support shaft 5 are protected, the damage of the spring 4 is reduced, and the guidance of the support shaft 5 is convenient.
[0030] Reference Figure 5 The elastic support component also includes a shock-absorbing pad 6, which is arranged at the bottom of the sleeve 3. The shock-absorbing pad 6 is in contact with the support shaft 5. The shock-absorbing pad 6 is a rubber pad. The setting of the shock-absorbing pad 6 can further improve the shock-absorbing effect.
[0031] Reference Figure 6 The elastic support assembly also includes a wear-resistant plate 10, which is connected to the support plate 2. The wear-resistant plate 10 and the support shaft 5 correspond one to one. The wear-resistant plate 10 is mounted on the support shaft 5. The wear-resistant plate 10 is in contact with the limiting wheel 7. The wear-resistant plate 10 is preferably a wear-resistant steel plate. Through the setting of the wear-resistant plate 10, the wear-resistant plate 10 is in contact with the limiting wheel 7. When the position of the limiting wheel 7 is adjusted, the limiting wheel 7 is in contact with the wear-resistant plate 10, instead of the limiting wheel 7 being in contact with the support plate 2, thereby reducing the wear of the limiting wheel 7.
[0032] Reference Figure 6The elastic support assembly also includes a limiting nut 8, each support shaft 5 is connected to a limiting nut 8, one end of the limiting nut 8 is in contact with the limiting wheel 7, the support shaft 5 and the limiting nut 8 are connected by threads, and the position of the limiting wheel 7 is limited by the setting of the limiting nut 8, thereby further reducing the loosening of the limiting wheel 7.

The hook 16 can be hung on the positioning holes on the extension plate 11 and the extension plate 2 18. Through the setting of the hook assembly, the hook 16 can be hooked on the extension plate 11 after adjustment to limit the movement position of the support plate 2. The hook assembly limits the position of the support plate 2, thereby reducing the situation where the support plate 2 moves excessively and falls off. The hook 16 can be rotated through different adjustment positions to adjust the combined length of the connecting rod 14 and the hook 16, thereby further facilitating the length adjustment of the hanging position.
