Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the body-benefiting lifting table of the present invention comprises a table body 1 and a table plate 2, wherein the front and back sides of the table plate 2 are respectively connected with the table body through a supporting mechanism and a lifting mechanism;

the lifting mechanism comprises a transmission rod 3, a sleeve 4, a worm wheel 5 and a worm 6, wherein the upper half part of the transmission rod 3 is provided with an external thread 31, the lower half part of the transmission rod 3 is a guide rod 32 with a rectangular section, the transmission rod 3 is inserted into the sleeve 4, the upper end of the sleeve 4 is provided with an internal thread 41 matched with the external thread 31, the external thread 31 and the internal thread 41 have a self-locking function, the worm wheel 5 and the worm 6 are arranged in a driving shell 42 positioned in the middle part of the sleeve 4, the worm 6 drives the worm wheel 5 to rotate, the middle part of the worm wheel 5 is provided with a guide hole 51 matched with the guide rod 32, the upper end of the transmission rod 3 is rotatably connected with the table plate 1 through a bearing 33, the guide rod 32 at the lower part is slidably inserted into the guide hole 51, and the sleeve 4 is fixedly connected with the table body 1;

as shown in fig. 2, the supporting mechanism includes a connecting rod 7 and a sliding groove 12 located on the bottom plate 11 of the table body 1, the upper end of the connecting rod 7 is hinged to the table 2, the lower end of the connecting rod is hinged to the sliding block 71, the sliding block 71 is slidably connected to the sliding groove 12, a locking mechanism is arranged on the sliding block 71, the length direction of the sliding groove 12 is consistent with the front-back direction of the table 2, and the front end of the sliding groove is not beyond the hinge point of the table 2 and the connecting rod 7.

The utility model discloses an accommodation process is: when the height of the table plate 2 needs to be adjusted, firstly, the locking mechanism on the sliding block 71 is loosened, then the worm 6 is rotated, the worm wheel 5 drives the transmission rod 3 to rotate through the guide hole 51, and the transmission rod 3 moves upwards or downwards under the action of the internal thread 41 of the sleeve 4 in the rotating process, so that the lifting of the table plate 2 is realized, and the limiting can be carried out under the self-locking action of the thread. In the process, the worm wheel 5 is in sliding connection with the guide rod 32 at the lower part of the transmission rod 3, so that the worm wheel 5 can drive the transmission rod 3 to rotate and simultaneously cannot influence the vertical movement of the transmission rod 3. Meanwhile, the upper end of the transmission rod 3 is connected with the table plate 2 through a bearing 22, and the connecting rod 7 at the front end of the table plate 2 can limit the table plate 2, so that the table plate 2 is prevented from rotating along with the rotation of the transmission rod 3. In addition, connecting rod 7 and slider 71 also can deflect and slide along with the lift of table 2, and when the adjustment back that targets in place, accessible locking mechanism locks slider 71 and spout 12, because spout 12 front end is no longer than the pin joint of table 2 and connecting rod 7, connecting rod 7 can be in the tilt state all the time, consequently accessible bending in advance makes connecting rod 7 can play certain supporting role to table 2.

For the rotation of the worm 6, a manual or electric mode can be adopted, and if the manual mode is adopted, a manual rocking handle can be arranged at the end part of the worm 6; if electric drive is used, the shaft of the motor 8 can be connected to the worm 6 via a coupling sleeve, as shown in fig. 3.

As for the installation mode of the worm wheel 5, the present application provides two structural forms, one is that the worm wheel 5 is limited in the axial direction by the upper and lower inner surfaces of the driving shell 42, that is, the thickness of the worm wheel 5 is close to the thickness of the inner cavity of the driving shell 42, and the limitation can be performed by the guide rod 32 in the radial direction, the mode has the advantages of simple structure, and the disadvantage that the worm wheel 5 is in sliding friction with the driving shell when rotating, and needs to ensure good lubrication; the other is that the worm wheel 5 is rotatably connected to the inner surface of the drive housing 42 in the axial direction by a thrust bearing, and the friction force is smaller but the mounting structure is more complicated.

For the locking mechanism, two modes are provided, one mode is manual, namely the locking mechanism is a cam locking mechanism or a locking bolt, and the friction force between the sliding block 71 and the sliding groove 12 is increased through the cam or the bolt to realize locking; the other is automatic, namely the locking mechanism comprises a pull wire 9 arranged at the bottom of the transmission rod 3, and the pull wire 9 is wound to the front end of the sliding groove 12 through a plurality of fixed pulleys 91 and then is connected with the front end of the sliding block 71. The pull wire 9 can drive the sliding block 71 to move towards the front end of the sliding groove 12 along with the rising of the transmission rod 3, and when the transmission rod 3 descends, the sliding block 71 can move towards the rear end of the sliding groove 12 under the action of the table board 2, so that the pull wire 9 can take a tensioning effect on the sliding block 71, and the table board 2 is guaranteed to be supported by the connecting rod 7. In order to facilitate the movement of the slider 71 toward the rear end of the slide groove 12 when the table 2 is lowered, a tension spring 72 is provided between the rear end of the slide groove 12 and the rear end of the slider 71.

In order to reduce the length of the connecting rod 7, a support plate 21 bent downwards is arranged at the front end of the table plate 2, and the connecting rod 7 is hinged to the end of the support plate 21. Meanwhile, some space is reserved between the bottom plate 11 and the table plate 2 for placing articles, so that the practicability is improved.

Further, as shown in fig. 4, in order to improve the integrity of the table top 2 and the table body 1, the sleeves 4 may be directly used as the table legs of the table body 1.

The utility model discloses a threaded connection's transfer line and sleeve provide power as elevation structure, utilize the worm and worm wheel to come for the rotation of transfer line, can easily realize the random lift of table, the connecting rod that deuterogamies to have locking mechanism carries on spacingly and supports the table, the stationarity that the table goes up and down and the stability of structure have been guaranteed, the user can be according to the very convenient adjustment desktop height of the needs of oneself, thereby satisfy the official working requirement of oneself under multiple postures such as standing position of sitting, reach the healthy purpose of beneficial health, and has fine practicality and application prospect.
