According to another embodiment of the present invention, it is further included that the first protective layer is an asbestos layer.

According to another embodiment of the present invention, the second protective layer is a rubber layer.

According to the utility model discloses a further embodiment, further include be fixed with the spout on the plane of wheel body, be fixed with the slider on the protecting crust, the slider cooperatees with the spout.

According to the utility model discloses a further embodiment, further include the telescopic link comprises piston rod and barrel, and in the piston rod top penetrated the barrel, the piston rod top was fixed with the spacing ring, and the opening of barrel can't be passed to the spacing ring, and the welding of barrel top is in the protecting crust, and the welding of piston rod bottom is on the plane of wheel body.

According to another embodiment of the present invention, it is further comprised that the elastic means is a spring.

The beneficial effects of the utility model are that, this utility model can carry out the protection of left and right sides face for the wheel body through gliding protecting crust. The elastic device is used for providing buffering, and the first protective layer is used for heat insulation protection. The second protective layer serves as an elastic support. The protection of the sprocket is improved.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a cross-sectional view of the protective shell of the present invention;

fig. 3 is a sectional view of the telescopic rod of the present invention;

in the figure, 1, a wheel body, 2 gear teeth, 3, a protective shell, 4, a first protective layer, 5, a second protective layer, 6, a telescopic rod, 7, an elastic device, 8, a sliding groove, 9, a sliding block, 61, a piston rod and 62, a cylinder body are shown.

Detailed Description

Fig. 1 is the structure schematic diagram of the present invention, fig. 2 is the sectional view of the protective shell of the present invention, and fig. 3 is the sectional view of the telescopic rod of the present invention. The utility model provides a protection type sprocket, includes wheel body 1 and the teeth of a cogwheel 2, evenly distributed has the teeth of a cogwheel 2 on the wheel body 1, all be connected with protection machanism on the tow planes of wheel body 1, protection machanism is by protecting shell 3, protecting shell 3 sliding fit connects on the plane of wheel body 1, protecting shell 3 is the annular casing, protecting shell 3 internal fixation has inoxidizing coating one 4, inoxidizing coating two 5,

telescopic link

6, 6 one end of telescopic link is fixed on protecting shell 3, the 6 other end of telescopic link is fixed on the plane of wheel body 1, be connected with resilient means 7 between inoxidizing coating two 5 and the plane of wheel body 1, telescopic link 6 passes inoxidizing coating one 4, inoxidizing. The first protective layer 4 is an asbestos layer. The second protective layer 5 is a rubber layer. A sliding groove 8 is fixed on the plane of the wheel body 1, a sliding block 9 is fixed on the protective shell 3, and the sliding block 9 is matched with the sliding groove 8. The telescopic rod 6 is composed of a piston rod 61 and a cylinder 62, the top end of the piston rod 61 penetrates into the cylinder 62, a limiting ring is fixed at the top end of the piston rod 61 and cannot penetrate through an opening of the cylinder 62, the top end of the cylinder 62 is welded in the protective shell 3, and the bottom end of the piston rod 61 is welded on the plane of the wheel body 1. The elastic means 7 is a spring.

Referring to fig. 1, 2 and 3, when an object impacts the two sides of the wheel body 1, the object will first touch the protective shell 3. The protective shell 3 will slide towards the wheel body 1. In the sliding process, the sliding block 9 on the protective shell 3 slides linearly along the sliding groove 8. And the elastic device 7 can absorb part of the impact force and plays a role in buffering and supporting. While the piston rod 61 can slide along the cylinder 62. The first protective layer 4 and the second protective layer 5 can increase the structural strength of the protective shell 3, and the second protective layer 5 made of rubber provides buffer protection. And the first protective layer 4 made of asbestos can insulate heat and increase buffer isolation. Providing good protection for the two sides of the wheel body 1.
