Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

It should be noted that the terms "upper", "lower", "left" and "right" used in the following description refer to directions in the drawings of the specification.

Example 1

A sidewalk comb iron plate is arranged at the outlet end of a moving sidewalk, as shown in figure 1: including fishback 10 and set up in a plurality of broach 20 of fishback 10, eccentric driving fit wheel 21 is established respectively to broach 20 both sides face, and eccentric driving fit wheel 21 passes through eccentric orfice and 20 hinges with the broach for eccentric driving fit wheel 21 can eccentrically rotate on broach 20, thereby make the eccentric driving fit wheel 21 of the tooth 31 left and right sides fill the clearance between its and the 30 tooth 31 of pavement step footboard through eccentric rotation, thereby reach sealed purpose of preventing pressing from both sides.

In order to ensure that the eccentric driving fit wheel 21 can be tightly attached to the tooth element 31 when the eccentric driving fit wheel 21 rotates eccentrically, the fastening element 22 is arranged between the eccentric driving fit wheel 21 and the comb teeth 20, the fastening element 22 can be a spring, when the tooth element 31 enters a gap between two adjacent comb teeth 20, according to the direction shown in the figure, the tooth element 31 exerts upward force on the eccentric driving fit wheel 21, and the fastening element 22 exerts force on the eccentric driving fit wheel 21 to prevent the eccentric driving fit wheel 21 from rotating, so that the eccentric driving fit wheel 21 is always attached to the side surface of the tooth element 31 to form a sealing structure to achieve an anti-pinch effect. Meanwhile, the elastic contraction of the spring can enable the eccentric closing wheel 21 to be matched with the tooth piece 31 in different widths, and the eccentric closing wheel 21 can be always attached to the tooth piece 20 no matter how the tooth piece 31 swings in the gap of the comb teeth 20 and no matter how the width of the tooth piece 31 changes.

The outer diameter of the eccentric driving wheel 21 should be not less than the maximum distance from the side of the tooth 31 to the side of the adjacent comb tooth 20, in this embodiment, the outer diameter of the eccentric driving wheel 21 is equal to the maximum distance from the side of the tooth 31 to the side of the adjacent comb tooth 20, when the fastener 22 is not stressed, the farthest point of the eccentric driving wheel 21 from the eccentric hole 21a on the adjacent two comb teeth 20 is tangent, so that the tooth 31 can be easily pushed open just before passing through the gap between the comb teeth 20, and unnecessary friction loss is reduced.

The fastening member 22 not only provides resistance to the eccentric driving wheel 21, but also prevents the eccentric driving wheel 21 from rotating excessively, and in order to further prevent the eccentric driving wheel 21 from rotating excessively and then not to be attached to the tooth member 31, the comb teeth 20 are provided with a limit groove 23 for limiting the rotation range of the eccentric driving wheel 21.

The eccentric driving fit wheel 21 can be a ball or a wheel with an eccentric hole, but because the contact surface of the wheel is larger than that of the ball when the eccentric driving fit wheel is tangent, the needed material is less, so in the embodiment, the eccentric driving fit wheel 21 is an eccentric wheel, and the anti-pinch roller 24 arranged below is the same.

Meanwhile, since the gear 31 generates a rattling motion and a friction between the two eccentric wheels 21, the eccentric wheels 21 are selected to be hard rubber wheels having wear resistance.

In addition, as shown in fig. 2, broach 20 still prevents pressing from both sides gyro wheel 24, prevent pressing from both sides gyro wheel 24 and be connected with power component, power component can be the motor, set up on the motor output shaft that the transmission gear transmission prevented pressing from both sides the gear that sets up in the middle of gyro wheel 24 can to make prevent pressing from both sides gyro wheel 24 and rotate outside broach 20 under power component's drive, promptly in the drawing, set up in the left anti-pinch gyro wheel 24 anticlockwise rotation of preventing of broach 20, set up and prevent pressing from both sides gyro wheel 24 clockwise rotation on broach 20 right side. Therefore, when the teeth 31 carry the foreign objects upward into the gaps between the comb teeth 20 in the direction of the drawing, the anti-pinch roller 24 applies a downward force to the foreign objects, thereby discharging the foreign objects.

In this embodiment, the anti-pinch roller 24 is disposed on the side of the comb teeth 20, and the sealing function of the eccentric driving wheel 21 and the rejection function of the anti-pinch roller 24 are generated sequentially. Because tooth 31 can rock in the broach 20 clearance, and tooth 31's width probably is nonstandard, the condition that the width differs everywhere exists, consequently two adjacent broach 20 prevent that the minimum distance between the pinch roller 24 is not less than tooth 31's minimum width to will prevent that pinch roller 24 sets up to soft rubber wheel, still have better elasticity when soft rubber wheel is wear-resisting, the different tooth 31 condition of ability adaptation.

Example 2

The structure of this embodiment is substantially the same as that of embodiment 1, and the difference is only the structure of the anti-pinch roller 24, and the structure is the same and will not be described in detail.

As shown in fig. 3, in the embodiment, the anti-pinch roller 24 is annularly disposed on the outer surface of the eccentric driving wheel 21, and the sealing function of the eccentric driving wheel 21 and the rejection function of the anti-pinch roller 24 occur at the same time. The power part can be a transmission gear on the output shaft of the motor, and the gears arranged in the middle of each anti-pinch roller 24 are meshed with the transmission gear in an annular mode to drive the anti-pinch rollers 24 to rotate towards the same direction. When the teeth 31 pass between the two eccentric wheels 21, the anti-pinch roller 24 is kept in contact with the teeth 31 as the side surface of the eccentric wheel 21, and on the other hand, rotates in the opposite direction to the advancing direction of the teeth 31 to achieve the rejection effect.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
