Detailed Description

The utility model is explained in more detail below with reference to the figures and examples.

The embodiment of the utility model provides a height-adjustable mechanical folding table, which comprises a first table top 1, a second table top 2 and a third table top 3, wherein fixing rods 23 are fixedly arranged below the first table top 1 and the third table top 3, connecting blocks 24 are fixedly arranged below the fixing rods 23, transmission rods 11 are fixedly arranged on one sides of the connecting blocks 24, the other ends of the transmission rods 11 are movably connected to two ends of a turntable 16, a transmission shaft 9 is movably arranged above the turntable 16, a supporting rod 14 is fixedly arranged below the transmission shaft 9, a buffer column 8 is fixedly arranged above the turntable 16, and support columns 10 are movably arranged at two ends of the turntable 16.

In this embodiment, through the cooperation of the first tabletop 1, the second tabletop 2, the third tabletop 3, the fixing rod 23, the connecting block 24, the transmission rod 11, the turntable 16, the transmission shaft 9, the supporting rod 14, the buffering column 8 and the supporting column 10, when the tabletop is to be stretched, the first tabletop 1 and the third tabletop 3 are pulled towards two sides, so that the gear 17 on the right protection plate 12 rotates, then the left rack 7 and the right rack 15 move along with the rotation of the gear 17, simultaneously, the transmission shaft 9 rotates the turntable 16 due to the pulling force, so that the supporting column 10 is away from the upper surface of the supporting rod 14, then the supporting column 10 drops downwards due to nothing supported by the lower surface, so that the second tabletop 2 rotates along with the rotation of the turntable 16, and simultaneously drops down due to the descending of the supporting column 10, then the buffering column 8 plays a role in buffering and supporting for keeping the heights of several tabletops consistent, when the folding table is retracted, the first table top 1 and the third table top 3 are pushed inwards, so that the gear 17 on the right protection plate 12 rotates reversely, then the left rack 7 and the right rack 15 move reversely along with the reverse rotation of the gear 17 to close the folding table, and meanwhile, the transmission shaft 9 rotates reversely the turntable 16 under the action of pulling force, so that the support column 10 returns to the upper surface of the support rod 14 to lift the second table top 2, and then the second table top 2 covers the first table top 1 and the third table top 3 under the action of the reverse rotation of the turntable 16.

Specifically, the equal fixed mounting in both sides below first desktop 1 has left stopper 6, the equal fixed mounting in one side of left stopper 6 has left rack 7, the equal fixed mounting in both sides below third desktop 3 has right stopper 18, the equal fixed mounting in one side of right stopper 18 has right rack 15, equal movable mounting has gear 17 between left rack 7 and the right rack 15, through first desktop 1, left stopper 6, left rack 7, third desktop 3, right stopper 18, right rack 15 and gear 17's cooperation for first desktop 1 and third desktop 3 follow left rack 7 and right rack 15 and move along with gear 17 rotates, and right stopper 18 and left stopper 6 then are used for restricting the displacement of left rack 7 and right rack 15, prevent tensile or shrink excessively.

Specifically, the equal fixed mounting in both ends below the bracing piece 14 has first lifter 19, equal movable mounting has second lifter 21 below first lifter 19, equal movable mounting has fastener 20 between first lifter 19 and the second lifter 21, fixed mounting has horizontal pole 22 below the second lifter 21, the equal fixed mounting in both ends of horizontal pole 22 has supporting leg 5, the equal fixed mounting in both ends below supporting leg 5 has blotter 4, through bracing piece 1, first lifter 19, second lifter 21, fastener 20, horizontal pole 22, supporting leg 5 and blotter 4's cooperation, during the lift, not hard up fastener 20 goes up and down first lifter 19 and second lifter 21, then screws up fastener 20, makes it fixed, and blotter 4 plays buffering and cushioning effect.

Concretely, the equal fixed mounting in one side of left stopper 6 has left guard plate 13, the equal fixed mounting in one side of right stopper 18 has right guard plate 12, the equal movable mounting in one side of right guard plate 12 has gear 17, and through the cooperation of left stopper 6, left guard plate 13, right stopper 18, right guard plate 12 and gear 17, left guard plate 13 and right guard plate 12 then prevent to have the thing card in the gear, and right stopper 18 and left stopper 6 then are used for restricting the displacement distance of left rack 7 and right rack 15, prevent to stretch or contract excessively.

Specifically, the first tabletop 1, the second tabletop 2 and the third tabletop 3 are all rectangular, the second tabletop 2 is the first tabletop 1 and the third tabletop 3 in size, the transmission rod 11 is in an oblique L shape, and the first tabletop 1, the second tabletop 2, the third tabletop 3 and the transmission rod 11 are matched to enable the size proportion and the shape to be stable.

All the electric equipment in the scheme supplies power through the external power supply.

The working principle is as follows: when the table is used, when the table is stretched, the first table top 1 and the third table top 3 are pulled towards two sides, the gear 17 on the right protective plate 12 rotates, then the left rack 7 and the right rack 15 move along with the rotation of the gear 17, the transmission shaft 9 rotates the rotary table 16 due to the pulling force, the support column 10 leaves the upper surface of the support rod 14, then the support column 10 drops downwards due to the fact that nothing is below the support column, the second table top 2 rotates along with the rotation of the rotary table 16, meanwhile, the support column 10 descends due to the descending of the support column, then the buffer column 8 plays a role in buffering and supporting, the heights of the table tops are kept consistent, when the table is contracted, the first table top 1 and the third table top 3 are pushed inwards, the gear 17 on the right protective plate 12 rotates in the reverse direction, then the left rack 7 and the right rack 15 move in the reverse direction along with the reverse direction of the gear 17, make it closed, make transmission shaft 9 simultaneously because the effect of pulling force with carousel 16 antiport, make support column 10 return to the bracing piece 14 the higher authority, raise second desktop 2, then second desktop 2 covers the higher authority of first desktop 1 and third desktop 3 because the antiport of carousel 16, when going up and down, not hard up fastener 20 goes up and down first lifter 19 and second lifter 21, then tighten fastener 20, it is fixed to make it, blotter 4 plays buffering and cushioning effect, the stopper is then used for restricting the displacement distance of left rack 7 and right rack 15, it is excessive to prevent to stretch or shrink, left guard plate 13 and right guard plate 12 then prevent that there are things to block in gear 17.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
