Description

Desk with elevating function

Technical field

The utility model relates to a kind of desk, and particularly a kind of user can use control device to drive two lowering or hoisting gears and linkage simultaneously to adjust the desk with elevating function of desk platform and ground distance towards the desk front end.

Background technology

Early stage desk also can't or highly be adjusted according to user's demand in the use generally all for level altitude designs, quite inconvenience in the use.

Therefore there is the same table of the lift adjustment of being available for users to come out then, for example: a kind of same table, this same table is provided with a pin, be provided with bracing frame in the table pin, be pivoted with two in the bracing frame upper end and adjust connecting rod, be provided with the double wedge that to be meshed relatively in two lower ends of adjusting connecting rod, and the support that two tops and of adjusting connecting rods are fixedly arranged on the fixed bar below the desktop is connected, and is provided with fulcrum in the support, and the fulcrum two ends are respectively equipped with reverse external screw thread, and fulcrum two ends spiral shell is provided with one and adjusts seat, adjust seat and articulate with adjusting connecting rod by a pivot, in addition, the sidewall of support is provided with chute, stretch through for pivot, an end of support is provided with a rocking handle and is connected with fulcrum.

When needs are adjusted height of table top, utilize the rotation rocking handle, drive fulcrum rotation in the support by rocking handle, the adjustment seat that is oppositely arranged on the fulcrum can displacement to the left or to the right under screw thread drives, and then two of interlocks adjust the relative closing of connecting rod or open, and have reached the function of adjusting height of table top.

But joystick is located at support one end and is protruded desktop one side, cause the side that this same table joystick protrudes desktop can't lean on wall, limit to some extent when causing the waste in space and space to arrange, and personnel are when the other walking of this same table, more there is clothing to be colluded, produces the doubt on the safety by rocking handle.

So, shortcoming at above prior art, someone has proposed to improve one's methods, illustrate: as Chinese patent application number several No. 200820117373.7 " same table " patents, its improvement is that connecting rod is arranged between two adjustable shelfs of foot rest unit, the two ends of connecting rod are respectively by the locating hole on the upper frame body of two adjustable shelfs, and then be connected with corresponding helical gear engaging groove, can make these a plurality of helical gears that are positioned at the connecting rod both sides produce continuous action relation thus, rocking handle then is to have a shape and the corresponding axis part of each engaging groove.

In the time will carrying out Height Adjustment, the axis part of rocking handle is inserted in the perforation of table, and then be embedded in the opening helical gear engaging groove up, the rotation rocking handle, this helical gear rotation that can be connected by the axis part interlock of rocking handle, and then interlock and other helical gear rotation of bridle joint mutually of this helical gear, synchronous interlock bar each sleeve telescopic displacement relatively that respectively is spirally connected, see through the synchronous interlock effect that transmission produced of connecting rod simultaneously, make table under the flexible drive of the bar that is spirally connected, to carry out the ascending, descending displacement.Again when table reaches suitable height, the user more rocking handle can be got from.

But, the user for the convenience of using desktop rocking handle must be got from, this action is still and has caused the sizable inconvenience of user, if rocking handle is lost accidentally, is equivalent to same table and loses function fully, therefore, this same table reliability is still quite low.

Because the problem of above-mentioned prior art can't effectively solve and overcome, so the applicant proposes present patent application, to solve problem point.

Can summarize the desk that the utlity model has elevating function according to the above has the following advantages:

1. the utlity model has the desk of elevating function, the user can rotate this rocking handle towards the front end of this platform, thus, this rocking handle drives this expansion link, and this expansion link drives the 3rd bevel gear and the 4th bevel gear of this bull stick, the 4th bevel gear drives this screw rod rotation, this screw flight portion is rotated relative to the screw of this swivel nut, and first bevel gear of this screw rod drives second bevel gear of this trace, relative this second support of first support that makes this two lowering or hoisting gear drive this bracing or strutting arrangement simultaneously vertically moves, thus, this control device drives two lowering or hoisting gears and linkage simultaneously and reaches the function of adjusting desk platform and ground distance.

2. the utlity model has the desk of elevating function, the user can promote this rocking handle to be extended to this back extreme direction by this front end, makes this bull stick slippage relatively of this expansion link, makes the not protruding front end that exposes this platform of this rocking handle.

3. the utlity model has the desk of elevating function, two guide pillars of this first support are slidedly arranged in the outer tube of this second support, when making the desk synchronization lifting, this first support can not be offset this second support, reach the effect of mean forced, the situation that makes the unbalance stress of inner body can be the time cause assembly to damage because of lifting.

Only the above, it only is preferred embodiment of the present utility model, when can not with the scope implemented of qualification the utility model, so the change of numerical value or displacement of equivalent elements such as, or, all should still belong to the category that the utility model patent contains according to equalization variation and modification that the utility model claim is done.
