The specific embodiment
In order more clearly to understand technology contents of the present invention, especially exemplified by following examples, describe in detail.
This plastic bottom board table trolley, comprise base plate 1 and rear hurdle 4, bottom and base plate 1 pivot joint on hurdle 4 after this, and limit, the left side pivot joint on left hurdle 2 and rear hurdle 4, the right edge pivot joint on right hurdle 3 and rear hurdle 4, left hurdle 2 is by wedge shape self-locking connecting device and 4 lockings of rear hurdle; The bottom on left hurdle 2 has left hurdle head, and the bottom on right hurdle 3 has right hurdle head, and base plate 1 is by base plate pin rod rotary self-locking device and left hurdle head and the locking of right hurdle head; Base plate pin rod rotary self-locking device comprises turn bar 5, this turn bar 5 is arranged in the bottom plate groove 6 of base plate 1 lower surface, the centre portion of turn bar 5 freely rotates with respect to base plate 1, and, when the centre portion of turn bar 5 rotates with respect to base plate 1, the two ends Yu Zuo hurdle head of turn bar 5 and right hurdle head card are established or break away from.
The left and right sides of base plate 1 all has buckle, and left hurdle 2 and right hurdle 3 all have corresponding draw-in groove, and when this table trolley folds, the buckle of base plate 1 is arranged in corresponding draw-in groove.Left hurdle 2 and right hurdle 3 are respectively by tingle 11 and 4 pivot joints of rear hurdle, and the border tube on rear hurdle 4 is connected with tingle 11, and the border tube on left hurdle 2 rotates freely with respect to tingle 11; The border tube on rear hurdle 4 is connected with tingle 11, and the border tube on right hurdle 3 rotates freely with respect to tingle 11.The wedge shape self-locking connecting device
Comprise wedge shape mother tuber 12, this wedge shape mother tuber 12 is movably set between the border tube on the border tube on rear hurdle 4 and left hurdle 2, wedge shape mother tuber 12 moves up and down along the axis direction of the border tube on the border tube on rear hurdle 4 and left hurdle 2, the bottom of the border tube on the border tube on rear hurdle 4 and left hurdle 2 is provided with wedge shape sub-block 13, and wedge shape sub-block 13 and wedge shape mother tuber 12 are corresponding.When this table trolley is used, wedge shape sub-block 13 is established with wedge shape mother tuber 12 fixed cards, and left hurdle 2 is perpendicular to rear hurdle 4, and lock with rear hurdle 4 on left hurdle 2; When this table trolley folds, when wedge shape mother tuber 12 breaks away from wedge shape sub-block 13, left hurdle 2 freely rotates with respect to rear hurdle 4.Wedge shape sub-block 13 is positioned at the both sides of wedge shape mother tuber 12, and the both sides of wedge shape mother tuber 12 all have the opening corresponding with wedge shape sub-block 13, and the cross-sectional area of wedge shape sub-block 13 upper ends is less than the cross-sectional area of lower end, and the opening of the upper end of wedge shape mother tuber 12 is less than the opening of lower end.Base plate 1 is plastic material, lighter weight.
There is dovetail groove wedge shape mother tuber 12 inboards, glide and contact with wedge shape sub-block 13 inclined-planes by self gravitation, the upper end of wedge shape mother tuber 12 is osculum 121, lower end is large mouthful 122, and the upper end of wedge shape sub-block 13 is microcephaly 131, and lower end is major part 132, when microcephaly 131 and osculum 121 overlap fully, left hurdle 2 and right hurdle 3 all keep stationary states with rear hurdle 4, and left hurdle 2 is perpendicular to rear hurdle 4, and left hurdle 2 can't rotate.When folding, utilize external force that the shrinkage pool of wedge shape mother tuber 12 15 is upwards stirred, wedge shape mother tuber 12 breaks away from wedge shape sub-block 13 fully, rotate left hurdle 2, wedge shape mother tuber 12 is glided, and offset with wedge shape sub-block 13 inclined-planes on left hurdle 2, can make rear hurdle 4 parallel with left hurdle 2, folded state completes.
During existing chassis finished product delivery, be generally to assemble to be folded into the L-type vanning, and adopted wedge shape self-locking connecting device of the present invention, but all inwardly folding deliveries of hurdle, left and right, in practical application, find, increase packing number more than 30%, thereby greatly reduce traffic cost, even and the site assembly wedge, substantially do not increase extra-pay, if existing chassis is also folding like this delivery, the site assembly bolt is pretty troublesome, and particularly foreign export labour cost is higher.
Adopted the plastic bottom board table trolley of this structure, base plate pin rod rotary self-locking device wherein can be by hurdle, left and right and base plate locking, in conjunction with the body mechanics, facilitate the user to operate, when the user carries while by handle, mentioning base plate, throw off naturally on base plate and hurdle, left and right, when the user puts down base plate, base plate and the locking of hurdle, left and right, reduce the operating time, and self-locking is very reliable; Wedge shape self-locking connecting device wherein is Jiang Zuolan and the locking of rear hurdle effectively, low cost of manufacture, a people gets final product complete operation, and all inwardly folding deliveries of hurdle, left and right, increase packing number more than 30%, thereby reduction traffic cost, even the site assembly voussoir does not increase expense substantially yet, folding table trolley is convenient to transportation, and is connected firmly while using, the assembling saving of labor is saved trouble, very quick.
In this specification sheets, the present invention is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
