The specific embodiment

To shown in Figure 7, a kind of folding table of the utility model comprises folding table body 1 and universal wheel body 3, and Collapsible rack 2 is installed on the table leg of described folding table body as Fig. 1, and described universal wheel 3 is installed on the Collapsible rack 2.

Above-mentioned Collapsible rack comprises down array structure: be fixedly mounted on the folding table body table leg bottom one side the first U-shaped support 21 and make the second hinged U-shaped support 22 of two support arms of its two support arm and the first U-shaped support by bearing pin; Pin shaft hole on the described second U-shaped support 22 is a strip poroid 221, the length direction in this strip hole 221 or inclination certain angle vertical with the base portion of the second U-shaped support 22, and make when described bearing pin is positioned at the second U-shaped support, 22 pin shaft holes bottom, the distance of the described second U-shaped support 22 from bearing pin to the support arm end is greater than the distance of bearing pin to the first U-shaped support, 21 bottoms, make the second U-shaped support 22 by locking, can not rotate by bearing pin; And when described bearing pin was positioned at the second U-shaped bracket pins axis hole top, the distance of the described second U-shaped support 22 from bearing pin to the support arm end was then less than the distance of bearing pin to the first U-shaped support, 21 bottoms, and at this moment, the described second U-shaped support 22 can rotate along bearing pin; Described universal wheel 3 is installed on the second U-shaped support 22.After adopting said structure, above-mentioned universal wheel can be folded up by folding rack, has reduced the unnecessary space that takies when folding, is easy to carry and stores.

As further improvement of the utility model, under the described second U-shaped support, 22 base portion table leg one side direction extroversion far away, be extended with one and support side arm 222, described universal wheel 3 is installed in and supports side arm 222 bottoms.Can make the center of gravity of folding table outwards expand like this, thereby make folding table more stable.

As further improvement of the present utility model, the described second U-shaped bracket base partly be provided with one with the suitable pre-locking bracket 23 of U-shaped elasticity of pin diameter.Can make folding table in use like this, slight, a spot of moving do not cause the second U-shaped support lock position of slipping away.

Above-mentioned folding wheel uses as follows: when folding table launches normal the use, the second U-shaped support 22 of folding rack is because the effect of gravity, make bearing pin be positioned at strip pin shaft hole 221 lower ends on the second U-shaped support 22, and because the distance of the second U-shaped support 22 from bearing pin to the support arm end is greater than the distance of bearing pin to the first U-shaped support, 21 bottoms, make the second U-shaped support 22 by locking, can not rotate by bearing pin, from forming stable state, but also bearing pin is dropped on the pre-locking bracket 23 of U-shaped elasticity of the second U-shaped support, 22 bottoms, and make folding table slightly, a spot of moving do not cause the second U-shaped support 22 lock position of slipping away; And when folding table becomes folded state, the described second U-shaped support 22 is pulled out downwards, make bearing pin break away from the pre-locking bracket 23 of U-shaped elasticity, and make bearing pin be positioned at strip pin shaft hole 221 upper ends on the second U-shaped support 22, because the distance of the second U-shaped support 22 from bearing pin to the support arm end is then less than the distance of bearing pin to the first U-shaped support, 21 bottoms, therefore, the second above-mentioned U-shaped support 22 can be turned to the first U-shaped support, 21 tops along bearing pin becomes rugosity to get final product.

As further improvement of the utility model, above-mentioned folding table comprises that two are gone up desktop 11, every lower surface two ends of going up desktop 11 are fixed with angle bar 12, the outer end of angle bar 12 flexibly connects U-shaped and supports 14, the inner of angle bar 12 connects by bolt, and simultaneously bolt also flexibly connects a folding compound hanger 15 with lock function.

The structure of above-mentioned compound hanger 15 is as follows, one upright arm 16 upper ends and above-mentioned bolt flexible connection, opposite side at last desktop has another upright arm 17, its upper end flexibly connects with another bolt, the lower end position of two

upright arms

16,17 is provided with and the folding following desktop 110 of going up desktop 11 same structures, respectively be provided with a locking cover 111 that flexibly connects in the upper end of two upright arms, on upright arm, be provided with movable sleeve 113, movable sleeve 113 is provided with a braking shoulder 114, is movably equipped with two poles on the movable sleeve 113 and supports 14 bottom with the U-shaped of both sides respectively and be connected.

As further improvement of the utility model, the lower end of locking cover 111 is a hook portion 112, and top is position, pushed section on.

The structure of embodiment of the present utility model is as follows: comprise that two are gone up desktop 11, every lower surface two ends of going up desktop 11 are fixed with angle bar 12, the outer end of angle bar 12 flexibly connects U-shaped and supports 14, key is that the inner of angle bar 12 flexibly connects by bolt, also flexibly connect simultaneously a folding compound hanger 15 with lock function on the bolt

The structure of above-mentioned compound hanger 15 is as follows, one upright arm upper end and above-mentioned bolt flexible connection, opposite side at last desktop has a upright arm upper end to flexibly connect with another bolt, two

upright arms

16,17 lower end and the folding following desktop 110 of going up the desktop same structure, two upright arm lower end positions be provided with folding on the following desktop of desktop same structure, two

upright arms

16,17 upper end respectively is provided with a locking cover 111 that flexibly connects, the lower end of locking cover 111 is a hook portion 112, the top of locking cover 111 is position, pushed section on, on two upright arms, respectively be provided with movable sleeve 113, movable sleeve 113 is provided with a braking shoulder 114, being movably equipped with two poles on the movable sleeve 113 supports 14 bottom with the U-shaped of both sides respectively and is connected, when desktop launches, after above-mentioned movable sleeve 113 rises to the top, the braking shoulder 114 on it and hook portion 112 interlocks of locking cover 111, two-layer desktop all launches, when promote or on locking cover 111 position, pushed section apply one make progress active force the time, locking cover 111 rotates an angle, hook portion 112 is thrown off with braking shoulder 114, continue to apply power upwards, then two U-shapeds supports 14 are drawn close mutually, each desktop is by the horizontal vertical configuration that becomes, otherwise then can become the horizontal development state by folded state.No matter the utility model folds or launches to be one, is easy to packing and transportation after folding, and expansion can be used, and has the desktop of two differing heights simultaneously, and is also very convenient during use.
