Embodiment

It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these embodiments.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of lifting structure of same table, including：Lifting support 100 and driving institute The drive component of the lifting of lifting support 100 is stated, lifting support 100 is actually the table leg of same table, to supporting desktop, and And furthermore, it is understood that the effect of this lifting structure is exactly the height for being used for adjusting desktop；Drive component is exactly to drive lifting support 100 elements lifted, by both combinations, realization automatically controls same table lifting, and also has convenient and simple, behaviour The advantages of making to facilitate.

The lifting support 100 includes outer tube 110, inner sleeve 120, support tube 130, nut casing 140, screw sleeve 150 and screw 160, in simple terms, outer tube 110, inner sleeve 120, support tube 130, nut casing 140, screw sleeve 150 with And screw 160 is set gradually from outside to inside, that is to say, that the latter is located at the former inside, and is preferably to be coaxially disposed.

What deserves to be explained is, screw 160 has external screw thread herein, and screw sleeve 150 has the internal thread being adapted to screw 160 And the external screw thread being adapted to nut casing 140, internal thread is provided with nut casing 140.

The screw 160 is threaded in the screw sleeve 150 and the screw 160 is protected with the support tube 130 Hold axial restraint, the screw sleeve 150 be threaded in the nut casing 140 and the screw sleeve 150 with it is described interior Casing 120 is held axially fixed, and the nut casing 140 is arranged in the support tube 130, and the support tube 130 is arranged on In the inner sleeve 120, the inner sleeve 120 is slidably disposed in the outer tube 110, the driving component with it is described Screw 160 is connected.

Screw 160 can rotate, so that while driving the rotation of screw sleeve 150, axial relative movement occurs in both, intuitively For, when being exactly that screw 160 rotates, 160 sets of screw can be axially moveable outside screw 160；And screw 160 and support tube 130 keep fixing, and when screw 160 rotates, support tube 130 can slide in inner tube, more precisely, when screw 160, by In the relation of threaded connection, support tube 130 can be stretched out or retracted in inner sleeve 120, so as to reach the effect of lifting.

Since screw 160 is when rotating, screw sleeve 150 can be driven to rotate, be between screw sleeve 150 and nut casing 140 It is threadedly coupled, so axial relative movement can occur, and because screw sleeve 150 is held axially fixed with inner sleeve 120, once Screw sleeve 150 moves axially, and inner sleeve 120 can also ensue relative movement, is exactly inner sleeve 120 intuitively It can stretch out or retract on outer tube 110, so as to fulfill the effect of lifting.

Above-mentioned structure, realizes that two-period form lifts, and can be adjusted automatically, so comparing when adjusting adjustable height It is convenient；Herein it is also worth noting that above-mentioned lifting structure is due to relatively rationally more ingenious, institute is so as to range is bigger.

As shown in Figure 2, Figure 4 shows, on the basis of above-mentioned embodiment, the driving component includes motor 200, described Motor 200 is connected with the screw 160, and the screw sleeve 150 is provided with internal thread and external screw thread, the screw 160 with The internal thread connection, the external screw thread are connected with the nut casing 140.

The structure of screw sleeve 150 is more ingenious, has internal and external threads, so axial shifting can not only be produced with screw 160 Dynamic effect, moreover it is possible to rotation is driven by screw 160, and the control of motor 200 get up it is more convenient, it is not necessary to manual operation just can Realize lifting.

As shown in Figure 1, on the basis of above-mentioned embodiment, the quantity of the lifting support 100 and the drive The quantity of dynamic component is two and corresponds setting, is provided between two lifting supports 100 for adjusting two The telescope support 400 of a 100 spacing of the lifting support.

The table leg of the namely same table of lifting support 100, it is preferably two, like this, when lifting it is more stable can Lean on, and telescope support 400 can also adjust the spacing between two lifting supports 100, allow whole same table according to need To adjust；Herein it is also worth noting that telescope support 400 can also provide the position of installation for drive component.

As shown in Figure 1, on the basis of above-mentioned embodiment, the telescope support 400 includes two support arms 410 And an inner support 420, two support arms 410 are socketed in the both ends of the inner support 420, by support arm 410 with it is interior The stretching structure that stent 420 forms, is not only simple in structure reliable but also very practical.

Herein it is worth noting that, support arm 410 have two it is parallel while and at two, between crossbeam, structure class Ladder is similar to, such 410 stressed effect of support arm is more preferable.

As shown in Figure 1, Figure 2, Figure 3 shows, on the basis of above-mentioned embodiment, peace is provided with the support arm 410 Mounted box 300, the top of the screw sleeve 150 are threaded through in the mounting box 300, and the motor 200 is arranged on the mounting box Engaged in 300 with the screw sleeve 150.

Support arm 410 is just analogous to trapezoidal, so can install a mounting box 300 within its two horizontal edges, installs Box 300 has the function of stress and provides motor 200 fixed position；In simple terms, since motor 200 is integrally fixed at mounting box In 300, and screw sleeve 150 is engaged through mounting box 300 with screw sleeve 150, so telescope support 400 can be driven to move up, So as to drive the desktop on telescope support 400.

As shown in Figure 1, Figure 2, Figure 4 shows, it is fixed in the nut casing 140 to set on the basis of above-mentioned embodiment It is equipped with nut (not marked in figure), screw sleeve 150 is actually to be threaded through in nut, so that screw sleeve 150 is when rotating, Axially opposite movement can be produced with nut casing 140.

As shown in figure 4, on the basis of above-mentioned embodiment, between the outer tube 110 and the inner sleeve 120 And it is both provided between the inner sleeve 120 and the support tube 130 and (is not marked in figure for the stop collar for keeping being coaxially disposed Go out), stop collar can make to keep coaxial between outer tube 110 and inner sleeve 120 and between inner sleeve 120 and support tube 130 Degree, so that above-mentioned tubular body is more smooth when sliding, is not likely to produce interference, and ensure to slide axially.

On the basis of above-mentioned embodiment, the bottom of the inner sleeve 120 has been wholely set end cap and (has not been marked in figure Go out), the end face of the end cap contradicts with the support tube 130 and the nut casing 140 and connects, and can so make overall knot Structure is more reasonable, and end cap can play the role of stress with being connected.

As shown in Figure 1, on the basis of above-mentioned embodiment, the bottom of the outer tube 110 is fixed with strip Feet 500.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
