Fig. 6 is the projection of flexible rod and the schematic diagram of stabilizing base, and this is the figure that sees after cutting open along the plane that comprises above-mentioned first and second directions, represents this both direction with D1 and D2 in the drawings, and this moment, metal gate was in the closed position;

Fig. 7 and Fig. 6 are similar, but in the figure, shown flexible rod and stabilizing base are in the position that is about to close at metal gate.

As shown in Figure 1, the road maintenance part that the present invention relates to mainly comprises a carriage 1, a metal gate 2 and a lid 4.

Metal gate 2 is contained in by a limit 21 on the limit 13 of correspondence of carriage 1, and this metal gate rotates between fastening position Z2 and open position A2, and when described fastening position, this metal gate covers the P1 of first (Fig. 1) of carriage.

Lid 4 itself is contained on another limit 14 of carriage 1 by first limit 41, and this covers between fastening position Z4 and open position A4 and rotates, and when described fastening position, this lid covers the second portion P2 of carriage 1.

As shown in Figure 1, when metal gate 2 and lid 4 were in the closed position, the inner edge separately 22 and 42 of metal gate and lid was connected to each other, and described inner edge 22 is relative with limit 21 and 41 respectively with 42, and metal gate and lid are hinged on the carriage by these two limits 21 and 41.

On the inner edge 22 relative of metal gate 2 one or more projections are arranged with carriage 1, for example projection 31, each projection is by free end 30 supportings of corresponding flexible rod, for example label 3, each projection all can be engaged in the stabilizing base 11 of carriage 1, thereby makes the metal gate 2 of Z2 in the closed position motionless on carriage 1.

Especially as shown in Figure 2, a groove 32 is arranged on the free end 30 of flexible rod 3, and the complementary protuberance 43 of inner edge 42 supportings of lid can be engaged in this groove, like this, after projection meshes in groove, just can make the lid 4 of Z4 in the closed position be fixed on the carriage 1 motionless by metal gate 2.

As shown in Figure 7,, limit stabilizing base 11 by limit 12 for the position that is about to close metal gate 2, projection 31 inclined planes 311 that have facing to limit 12, this can see in Fig. 7 and Fig. 3.

As shown in Figure 4, for the position that lid shown in this Fig 4 is about to close, projection 43 and groove 32 have the contact surface 431,321 that faces toward separately.

From this contact site, by the power F3 that affacts on the projection 43 projection 43 is engaged in the groove 32, the sensing of described power is identical with direction D3, and is vertical with direction D1, D2.

In fact, preferably power F3 is affacted certainly and cover, and lid is sent to this power on the projection 43 again.

In these situations, the contact between the contact surface 431,321 of projection 43 and groove 32 makes and occurs component F4 on the capable F3, and this component makes flexible rod 3 along direction D4 deflection, and this direction and direction D2 are reverse still point-blank.

Shown in Fig. 2 and 5,, also has stable inclined-plane vis-a-vis 432,322 separately on projection 43 and the groove 32 for the fastening position Z4 of lid 4.

When lid 4 is thrown off fastening position Z4, just can make projection throw off groove 32 by on projection 43, applying a power F5, the direction of power F5 and direction D3 are reverse still point-blank.

In these situations, being in contact with one another between the stable inclined-plane 432,322 of projection 43 and groove 32 makes and occurs component F40 on the capable F5, and this component makes flexible rod 3 along direction D4 deflection.

Can make and cover the 4 power F5 that throw off its fastening position Z4 and for example provided by an instrument, this instrument for example is thin bar or the pick that is inserted in the side channel of upper surface of lid.

Therefore, shown in situation in, the present invention can be separately move on to their open positions separately with lid and metal gate from their fastening positions separately, vice versa.
