Description of reference numerals: holder 1, car body 2, leading screw 3, screw 4, axle sleeve 5, stopper slot 6, interlocking device 7, chute 8, convex limiting plate 9, upper transfer gear 10, lower transmissioning gear 11, depression bar 12, reset tension spring 13, U type mount pad 14, arcuation flanging structure 15, cabinet door 16.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: this band in the present embodiment closes gate interlock chassis car, comprise holder 1, car body 2, described holder 1 is provided with leading screw 3, be provided with screw 4 in the car body 2, screw 4 is enclosed within leading screw 3 outer and leading screw 3 transmissions couplings, leading screw 3 ends are provided with axle sleeve 5, have the stopper slot 6 of a pair of symmetrical distribution on this axle sleeve 5, axle sleeve 5 outer ends have arcuation flanging structure 15, holder 1 faces axle sleeve 5 one sides and is provided with U type mount pad 14, be provided with in the U type mount pad 14 two with this interlocking device 7 to stopper slot 6 interlocking coupling.This interlocking device 7 comprises chute 8, has the convex limiting plate 9 of rack structure, upper transfer gear 10, lower transmissioning gear 11, the depression bar 12 with rack structure, reset tension spring 13, chute 8 is located at the above and below of U type mount pad 14, convex limiting plate 9 be slidingly arranged in 8 of chutes and with axle sleeve 5 on stopper slot 6 spacing couplings; Upper transfer gear 10 and lower transmissioning gear 11 coaxial vertically being located in the U type mount pad 14; The tooth bar of convex limiting plate 9 and lower transmissioning gear 11 engaged transmission; Depression bar 12 is vertical and be slidingly arranged on the U type mount pad 14, the tooth bar of this depression bar 12 and upper transfer gear 10 engaged transmission, and the length of depression bar 12 is greater than the degree of depth of U type mount pad 14; Reset tension spring 13 1 ends are connected with U type mount pad 14, the other end and 12 terminal connections of depression bar.
During use, the cabinet door is closed, at this moment cabinet door 16 touches depression bar, rack drives upper transfer gear 10 on the depression bar 12, because upper transfer gear 10 is coaxial with lower transmissioning gear 11, so in the time of the rack drives upper transfer gear 10 on the depression bar 12, lower transmissioning gear 11 is also rotating, and drive has the convex limiting plate 9 of rack structure, the projection of convex limiting plate 9 is extracted out in the stopper slot 6 of axle sleeve 5, stopped spacing to axle sleeve 5, at this moment operating personnel can insert 5 pairs of chassis cars of axle sleeve with rocking handle and carry out the go-cart operation under the situation that cabinet door 16 is closed; When cabinet door 16 is opened, cabinet door 16 has stopped the compacting of depression bar 12 spacing, depression bar 12 resets by reset tension spring 13, drive upper transfer gear 10 simultaneously, make lower transmissioning gear 11 convex limiting plate 9 be pushed on the axle sleeve to 5 stopper slot 6, axle sleeve 5 is spacing, and at this moment rocking handle can't insert axle sleeve 5, also just can't carry out the go-cart operation to the chassis car.Can effectively ensure operating personnel's safety like this, avoid taking place security incident.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
