The beneficial effects of the utility model are: by the adjustment of two cover elevating mechanisms to movable table leg, overcome the drawback that can only rely on alignment pin that table height is adjusted, realized the accurate adjustment to table height, satisfy different stature users' demand, Bevel Gear Transmission process with auto-lock function, stabilized structure, easy to operate, greatly simplified adjustment process.
Description of drawings
Fig. 1 is the structural representation of same table of the present utility model;
Fig. 2 is the local structure for amplifying schematic diagram of A section among Fig. 1;
Fig. 3 is the side-looking structural representation of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
In conjunction with Fig. 1 to Fig. 3, a kind of same table of the present utility model, this same table comprise desk for students, life with desk or work desk etc., and it comprises desktop 1, two fixedly table leg 4, two movable table legs 3, and elevating mechanism.One end of movable table leg 3 is connected with the bottom of desktop 1, and the other end is set in fixedly in the table leg 4, and fixedly the bottom of table leg 4 is provided with base, and base is provided with rubber antiskid lower margin 14.This elevating mechanism comprises: two gear units, 8, two stay pipes 9 of two adjusting screws and a power transmission shaft 2.Wherein, each gear unit comprises: intermeshing horizontal bevel gear 7 and vertical bevel gear 6, each vertical bevel gear 6 is connected with an adjusting screw 8.Connect by described power transmission shaft 2 between the horizontal bevel gear 7 in two gear units.This stay pipe 9 is made for metal and its cross section is square, and each stay pipe 9 is arranged on fixedly table leg 4 inside, and the top of stay pipe 9 is provided with internal thread, and described adjusting screw 8 is threaded with stay pipe 9.
By the adjustment of two cover elevating mechanisms to movable table leg, overcome the drawback that can only rely on alignment pin that table height is adjusted, realized the accurate adjustment to table height, satisfy different stature users' demand, Bevel Gear Transmission process with auto-lock function, stabilized structure, easy to operate, greatly simplified adjustment process.
Preferably, the inwall on the top of described stay pipe 9 is welded with and the corresponding metal adjusting nut 11 of its shape, and as its internal thread, described adjusting screw 8 is threaded by this metal adjusting nut 11 with stay pipe 9.By using metal nuts to be welded on the top inner wall of stay pipe, not only do not affect its overall appearance, and stabilized structure, easy to process.Described metal adjusting nut 11 models are M14, and described power transmission shaft 2 is foursquare metal drive shaft for cross section.
Preferably, this same table also comprises lifting handle 15 and gear-box 18.Described horizontal bevel gear 7 and vertical bevel gear 6 are arranged in the gear-box, two axle heads of this horizontal bevel gear 7 pass from gear-box respectively, one axle head is connected with described power transmission shaft 2 by adapter sleeve 16, when same table is operated, when needing this same table of lifting, another axle head is connected with described lifting handle 15, shakes this lifting handle, and driving gear set drives the lifting of leading screw control activity table leg.Described in the bottom near desktop, namely basal surface position is provided with hook 20, makes things convenient for the user to hang article.
Preferably, the axle head 5 on the bottom surface 71 of described horizontal bevel gear 7 is connected with described lifting handle 15.Concrete, as shown in Figure 2, this horizontal bevel gear 7 is divided into bottom surface 71 and the conical surface 72, and the top of the conical surface 72 has an axle head, and base 71 has another axle head, and the bottom surface is towards lifting handle, and its conical surface is back to lifting handle.Adopt this engagement system, when installing and rotate lifting handle, horizontal bevel gear can produce horizontal force to vertical bevel gear so that engagement is tightr during two bevel gears motions, between can not produce the slit, guarantee lifting efficient and operating handle.
