Specific implementation mode

It is the specific implementation mode of the present invention below, and in conjunction with attached drawing, technical scheme of the present invention work is further retouched It states, however, the present invention is not limited to these examples.

It should be noted that word "upper" used in the following description "lower" " left side " " right side " refers to Figure of description In direction.

Embodiment 1

A kind of novel pedestrian road broach iron plate, is set to the outlet end of moving sidewalk, as shown in Figure 1：Including 10 He of fishback Several broach 20 of fishback 10 are set to, 20 two sides of broach set eccentric closely sealed wheel 21 respectively, and eccentric closely sealed wheel 21 is by inclined Heart hole and broach 20 are hinged so that the closely sealed wheel of bias 21 can on broach 20 eccentric rotary, to make 31 left and right sides of tooth The closely sealed wheel of bias 21 its gap between 30 tooth 31 of pavement step pedal is filled by eccentric rotary, it is close to reach Seal the purpose of anti-pinch.

In order to ensure eccentric closely sealed wheel 21 can fit closely tooth 31, eccentric closely sealed wheel 21 and broach 20 in eccentric rotary Between be equipped with fastener 22, fastener 22 can be spring, when gap between tooth 31 enters adjacent two broach 20, according to Shown in direction in figure, tooth 31 plays the role of upward power to eccentric closely sealed wheel 21, and fastener 22 is to eccentric closely sealed wheel 21 Play the role of the power for preventing it from rotating so that eccentric closely sealed wheel 21 always fitting tooth 31 side to formed sealing structure with Reach anti-pinch effect.The elastic shrinkage of spring can make 21 width fits different from tooth 31 of eccentric closely sealed wheel simultaneously no matter How tooth 31 swings in 20 gap of broach, and no matter how the width of tooth 31 changes, and can make eccentric closely sealed wheel 21 always Fit in tooth 20.

The outer diameter of eccentric closely sealed wheel 21 should be not less than 31 side of tooth to the maximum distance of 20 side of adjacent fingers, this implementation In example, the outer diameter of eccentric closely sealed wheel 21 is equal to 31 side of tooth to the maximum distance of 20 side of adjacent fingers, when fastener 22 not When stress, the point farthest apart from eccentric orfice 21a is tangent on the closely sealed wheel 21 of bias of adjacent two broach 20 so that tooth 31 just starts , can be open-top by its easily when by 20 gaps of broach, reduce unnecessary friction loss.

Fastener 22 is not given only 21 drag effects of eccentric closely sealed wheel, while can also prevent eccentric closely sealed wheel 21 from excessively turning Dynamic, in order to no longer be bonded with tooth 31 after further preventing the excessively rotation of eccentric closely sealed wheel 21, it is close that broach 20 is equipped with limitation bias Close the limiting slot 23 of 21 slewing areas of wheel.

Eccentric closely sealed wheel 21 can be offer the ball or wheel of eccentric orfice, but due to it is tangent when, take turns the contact surface than ball Greatly, the required material used is few, therefore in the present embodiment, and eccentric closely sealed wheel 21 is set as eccentric wheel, the anti-pinch of following settings Idler wheel 24 is similarly.

Simultaneously as tooth 31 will produce shaking and friction, therefore eccentric closely sealed wheel 21 between two eccentric closely sealed wheels 21 It is selected as wear-resisting hard rubber wheel.

In addition, as shown in Fig. 2, broach 20 further includes anti-pinch idler wheel 24, anti-pinch idler wheel 24 is connected with force piece, and force piece can Think motor, the gear being arranged among anti-pinch idler wheel 24 is driven by the way that transmission gear is arranged on motor output shaft, so that Anti-pinch idler wheel 24 rotates under the drive of force piece to outside broach 20, i.e., in the accompanying drawings, is set to the anti-clamp roll in 20 left side of broach Wheel 24 rotates counterclockwise, and the anti-pinch idler wheel 24 for being set to 20 right side of broach rotates clockwise.Therefore, when tooth 31 drives foreign matter to press Direction in figure, when being upwardly into 20 gap of broach, anti-pinch idler wheel 24 gives foreign matter downward power, to which foreign matter to be discharged.

In the present embodiment, anti-pinch idler wheel 24 is set to 20 side of broach, the sealing process and anti-pinch of eccentric closely sealed wheel 21 The rejection effect of idler wheel 24 successively generates.Since tooth 31 can be shaken in 20 gap of broach, and the width of tooth 31 may not There is the case where width differs everywhere in standard, therefore the minimum range between the anti-pinch idler wheel 24 of adjacent two broach 20 is not less than The minimum widith of tooth 31, and set anti-pinch idler wheel 24 to soft rubber wheel, also have while soft rubber wheel is wear-resisting compared with Good elasticity, can be adapted to different 31 situations of tooth.

Embodiment 2

The structure of the present embodiment is substantially the same manner as Example 1, and the structure for differing only in anti-pinch idler wheel 24 is different, structure phase It is not described in detail with place.

As shown in figure 3, in the present embodiment, 24 ring-type of anti-pinch idler wheel is set to 21 outer surfaces of eccentric closely sealed wheel, eccentric closely sealed The rejection effect of the sealing process and anti-pinch idler wheel 24 of wheel 21 is happened at synchronization.Force piece at this time can be that motor is defeated Transmission gear on shaft, the gear ring-type being arranged among each anti-pinch idler wheel 24, which is engaged in transmission gear, can drive anti-pinch Idler wheel 24 turns in the same direction.When tooth 31 is by between two eccentric closely sealed wheels 21,24 one side of anti-pinch idler wheel is as inclined Side and tooth 31 holding of the closely sealed wheel of the heart 21 are bonded, another aspect, its own rotation opposite with 31 direction of advance of tooth is Reach rejection effect.
