Preferably, nylon angle case lid integrally be all have nylon alloy composition, and also carried out in the alloy glass and Minerals filling.

Preferably, the location hole is 8 points 8 grades of screw holes, and it is that copper facing steel bushing is inlayed that it is internal.

Preferably, the reinforcing rib is exceptional hardness steel.

Preferably, the inside between the fixed lid in the outside, the first rotary table ring and the second rotary table ring is seamless connection, entirely It is integrated, by single injection-molded.

Compared with prior art, the utility model has the beneficial effects that

1. nylon angle case lid needs to meet the requirement in -20 DEG C of -120 DEG C of temperature ranges, while size changing amount control System is in the fitted position margin of tolerance.

2. nylon angle case lid also meets certain intensity and toughness while guaranteeing dimensional stability, by strong external force Impact will not be burst.

3. nylon angle case lid needs to carry weight, meets certain pressure flatness and do not deform requirement.

4. nylon angle case lid is corrosion-resistant, non-corrosive, addition lubricating oil is not needed in use process.

5. substantially reducing noise in the case lid use process of nylon angle, energy conservation and environmental protection is met environmental requirements.

Detailed description of the invention

Fig. 1 is the utility model schematic bottom view；

Fig. 2 is the utility model upper end schematic diagram.

In figure: the fixed lid in 1 outside, 2 snap rings, 3 first rotary table rings, 4 location holes, 5 card slots, 6 fixed rings, 7 reinforcing ribs, 8 the Two rotary table rings, 9 screw thread through posts, 10 nut caps, 11 pull rings.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of crane nylon angle case lid, including outside Fixed lid 1, fixed 1 upper end of lid in outside are equipped with inside snap ring 2, and bottom end is connect with the major diameter bottom surface of the first rotary table ring 3, outside The upper end center of fixed lid 1 is symmetrically arranged with four location holes 4, and is not set between two location holes 4 there are two card slot 5, card slot 5 is located at The upper end of the fixed lid 1 in outside, the outside of the minor diameter bottom surface of the first rotary table ring 3 are connect with the major diameter bottom surface of the second rotary table ring 8, First rotary table ring, 3 minor diameter inside bottom surface center is equipped with fixed ring 6, and the side of fixed ring 6 is equipped with a plurality of reinforcing rib 7, reinforces The other end of muscle 7 is fixed on the medial surface of the first rotary table ring 3, and the minor diameter bottom surface of the second rotary table ring 8 and screw thread through post 9 connect It connects, the outside inner side and outer side of screw thread through post 9 is all equipped with screw thread, and outside screw is threadedly coupled with nut cap 10, and the bottom end of nut cap is set There is pull ring 11.
