Detailed Description

The following describes in detail an embodiment of the present invention with reference to the drawings.

The lift table of this embodiment adopts thereby the difference of rotation back height through a set of swing arm realizes the regulation to the table height, and not only simple to operate, swift can also reduce the cost of production, introduces in detail below:

in this embodiment, a lifting table, as shown in fig. 1-4, includes a table body 1 and a table component 11 capable of moving up and down, and can adjust to a suitable height according to the height of the crowd, the table component 11 below is movably connected with at least one group of swing arms 3, and one end of each swing arm 3 is engaged with each other and rotatably connected to the table body 1, and the other end of each swing arm 3 acts on the table component 11, so that the table component 11 descends along with the swing arm 3 when the swing arms 3 rotate to approach each other by jacking the table component 11 or the swing arms 3 rotate to separate from each other, and the engagement between the swing arms 3 enables two swing arms 3 to rotate when one of the swing arms rotates, the other swing arm also rotates along with the other swing arm, thereby ensuring the synchronism of the swing arms 3 rotation, and the synchronous rotation can effectively ensure the stability of the table component 11.

As shown in fig. 5, further, one end of the two sets of swing arms 3 is fixedly connected with an incomplete gear 4, and the two sets of swing arms are meshed with each other. Incomplete gear 4 one side still with connecting axle coaxial coupling, the connecting axle is connected on the table body 1, incomplete gear 4 can drive another meshed when it rotates and rotate together, also only needs adjustment swing arm 3 to same height in the production installation, can guarantee follow-up swing arm 3 in the use to the synchronous lift of table, has made things convenient for the installation, has also reduced the cost of production.

As shown in fig. 4 or 6, the table component 11 includes a table 2 and a support frame disposed below the table 2, the support frame includes two wing plates 5 that are bilaterally symmetric and a first cross beam 6 connected between the two wing plates 5, the table 2 is connected with the wing plates 5, and the other end of the swing arm 3 is movably connected with the first cross beam 6. First crossbeam 6 connects the stability that supports table 2 jointly between pterygoid lamina 5, makes simultaneously to be separated by a determining deviation between table 2 and the first crossbeam 6, consequently the activity external member freely can slide along its axial direction when swing joint is on first crossbeam 6, does not receive the hindrance of table 2 to interfere, and the activity external member rotates again and connects on swing arm 3, when swing arm 3 took place to rotate, thereby its high position changes and drives the activity external member and remove on first crossbeam 6, makes it go up and down to the table.

In a normal state, as shown in fig. 1, the table is at a normal height; when the height of the desk plate needs to be reduced, the swing arms 3 rotate towards the directions away from each other, so that the height of the desk plate is reduced, as shown in fig. 2; when the height of the table board needs to be lifted, the swing arms 3 rotate towards the direction close to each other, so that the height of the table board is lifted, as shown in fig. 3.

Swing arm 3 and first crossbeam 6 swing joint have following two kinds of modes:

first, as shown in fig. 6, the other end of the swing arm 3 is movably connected with the first beam 6: the other end of the swing arm 3 is rotatably connected with a movable external member which is connected on the first beam 6 in a sliding way. The movable external member comprises a group of surrounding members 7 which are matched, disassembled and connected, one side of each surrounding member 7 which is matched and connected is provided with a groove matched with the first cross beam 6, the grooves can clamp and embrace the side edge of the first cross beam 6, so that clamping action is realized, and the two surrounding members 7 are combined and assembled to embrace the first cross beam 6.

Secondly, as shown in fig. 7, the other end of the swing arm 3 is movably connected with the first beam 6, that is: the other end of the swing arm 3 is provided with a guide pin 12, a guide groove 13 is correspondingly arranged on the first cross beam 6, and the guide pin 12 is inserted in the guide groove; when the swing arm 3 rotates, the guide pin 12 slides along the guide groove 13. In the process of actual production and use, in order to reduce the generation of abrasion and noise, a bushing and the like can be sleeved between the two to eliminate influence.

Both types of mode can all make swing arm 3 rotate when changing the height, all can drive and embrace a 7 or guide pin and carry out the jacking or descend to first crossbeam 6, wherein encircle the connection of dismantling of 7 not only make the installation more convenient quick, can also adjust the centre gripping interval of embracing a 7 through the elasticity degree of bolt simultaneously to be fit for more and use with the cooperation of first crossbeam 6.

The desktop assembly further comprises a second cross beam 10, the second cross beam 10 and the first cross beam 6 are arranged in a spaced and balanced mode, a driven assembly is connected between the second cross beam 10 and the swing arm 3, and the driven assembly and the second cross beam 10 support the desktop assembly 11 along with the rotation of the swing arm 3. After realizing the regulation of table height, for guaranteeing that its steady operation in the use and table can bear great pressure, still be provided with driven subassembly in 3 one sides of swing arm, share the pressure that the table received on the one hand and transmit it for the second crossbeam, on the other hand can prevent that the table from taking place to deflect around first crossbeam, do following detailed introduction to driven subassembly:

in the first case, the driven assembly comprises a fixed shaft 8 and a transmission rod 9, the fixed shaft 8 is vertically connected to one side of the swing arm 3, and two ends of the transmission rod 9 are respectively hinged to the fixed shaft 8 and the second cross beam 10.

In the second case, the driven component is an integrally formed L-shaped rod, one end of the L-shaped rod is hinged to the swing arm 3, and the other end of the L-shaped rod is rotatably connected to the second beam 10.

The table body 1 is further provided with a driving device for assisting the movement of the table component 11 and stopping the table component 11 at a preset position, and the driving device is a gas spring or an electric push rod.

In the in-service use, when adopting the air spring as the helping hand, can install control switch in table 2 below, control switch and air spring connect, and the air spring both ends articulate respectively in swing arm 3 and table body 1, also can connect table body 1 and table subassembly 11 respectively with the air spring both ends, when raising or descending table 2 in needs, press the switch, the user makes progress the lifting or descends table 2 to a take the altitude after as required, unclamp the switch can.

When adopting electric putter as the helping hand, install on table 2 below or the table body 1 with electric putter electric connection's automatically controlled switch, electric putter both ends articulate respectively in swing arm 3 and table body 1, also can connect table body 1 and table subassembly 11 respectively with the air spring both ends, the user only needs to press the switch as required can control the lift, need not the user lifting or push down table 2.

The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
