In order to improve the stability and the mating strength of the plug-in mating of the plug-in portion 340 and the socket portion 250, the electric lifting table further comprises a locking component, and the locking component applies pressure to the socket portion 250 to improve the relative acting force between the plug-in portion 340 and the socket portion 250 in the plug-in mating state, and improve the static friction force between the contact surfaces of the plug-in portion and the socket portion, so that the plug-in mating state of the plug-in portion and the socket portion is maintained under the action of friction force. And under the effect of locking part, can not exist relatively rocking between electronic stand 300 and the girder 210, can guarantee that table 100 keeps steady in the use. The locking member may also press on the spigot portion or both the spigot and socket portions.

As can be seen from the friction formula, the pressing direction of the locking member is set to be perpendicular to the insertion direction of the insertion portion 340 and the socket portion 250, and the friction force added to the overlapping portion of the insertion portion 340 and the socket portion 250 is the maximum value, so that the mating strength of the insertion portion 340 and the socket portion 250 can be enhanced to the maximum extent.

If the force application direction of the locking component is not perpendicular to the inserting direction of the inserting portion and the socket portion, the force application direction has two component forces in the inserting direction and the inserting direction perpendicular to the inserting direction, wherein the component force perpendicular to the inserting direction can increase the matching strength between the inserting portion and the socket portion, but the value of the component force can be smaller than the acting force applied by the locking component.

Preferably, the end of the bracket 320 facing the rear side of the table 100 is provided with the plugging portion 340, the plugging portion 340 and the socket portion 250 are connected in an opposite manner in the front-rear direction of the table 100, the table 100 has a deformation trend in the use process, the deformation trend is that the middle of the table 100 is concave downwards, the two ends in the length direction are arched upwards, after the plugging portion 340 and the socket portion 250 are matched in a plugging manner, the socket portion 250 limits the plugging portion 340 in the length direction of the main beam 210, and the situation that two electric upright posts 300 are inclined outwards of the table 100 in the length direction of the main beam 210 when the table 100 bears a heavy object can be avoided. The locking member presses the socket 250 in the length direction of the girder 210.

In addition, when the socket 340 and the spigot 250 are engaged with each other in the check block 342 and the check groove 252, they can abut against each other to have a static friction force in the direction of insertion, thereby improving the engagement strength.

Referring to fig. 3 to 8 and 15, in one embodiment of the present invention, the locking member is preferably a sub-beam 220, and the sub-beam 220 is movable with respect to the main beam 210 to switch between a locking position for pressing the socket 250 and a releasing position for releasing the pressing. The auxiliary beam 220 is used for locking the main beam 210 and the electric upright 300, so that an additional structure for locking the main beam 210 and the electric upright 300 is not required for the electric lifting table, and an additional production line, a mould and the like are not required to be added for the electric lifting table, thereby increasing the production cost. Secondary beam 220 is movable relative to main beam 210 to remain in a released position during assembly of power column 300 with main beam 210 without interfering with the mating of power column 300 with main beam 210. As shown in fig. 7, the secondary beam is in the locked position in fig. 7, and as shown in fig. 15, the secondary beam is in the released position in fig. 15.

Referring to fig. 7 and 8, in one embodiment of the present invention, the sub-beam 220 is provided with a protrusion 221, and the sub-beam 220 is pressed against the socket 250 by the protrusion 221 when it is in the locking position to maintain the coupled state of the two. The auxiliary beam 220 contacts the socket part 250 through the protrusion 221 so as to press the socket part 250, and the protrusion 221 concentrates the acting force in a small area range so as to avoid the insufficient fitting strength between the socket part 340 and the socket part 250 due to the excessive dispersion of the acting force. And no force is applied to the rest of the parts except the socket 340 and the spigot 250.

The auxiliary beam 220 is rotatably connected with the main beam 210 to switch between a locking position for applying pressure to the socket part 250 and a releasing position for releasing the pressure, the auxiliary beam 220 is further provided with a cam structure 222, the cam structure 222 takes the rotation center of the auxiliary beam 220 as the center of a circle, the convex part 221 is formed by the cam structure 222, the cam structure 222 is an eccentric structure, the convex part 221 can be naturally formed by the cam structure 222, and the contour of the convex part 221 formed by the cam structure 222 is an arc structure, so that the self or the plug part 340 or the socket part 250 is not easy to be damaged. As can be seen from the lever principle, the closer the cam structure 222 is to the rotation center, the smaller the force required by the user to switch the auxiliary beam 220 to the locking position, in this embodiment, the center of the circle of the cam structure 222 is the rotation center of the auxiliary beam 220, i.e. when the auxiliary beam 220 rotates relative to the main beam 210, the cam structure 222 rotates, and the most labor-saving scheme is to set the center of the circle of the cam structure 222 on the rotation center of the auxiliary beam 220.

And since one end of the sub-beam 220 is connected to the main beam 210, when the sub-beam 220 is at the release position, one end of the sub-beam 220, which is close to the main beam 210, does not protrude from the end of the main beam 210, so that the overall length is not increased to increase the packaging and transportation costs.

When the auxiliary beam 220 is located at the release position, the auxiliary beam 220 is folded on the main beam 210 along the length direction of the main beam 210, so that the space occupied by the frame 200 can be reduced, the packaging space required by the frame 200 can be saved, and the transportation cost can be reduced. The sub-beam 220 includes a first beam 223 disposed along the lower surface of the table 100 and a second beam 224 extending from a side edge of the first beam 223 in a height direction, wherein when the sub-beam 220 is in the release position, the second beam 224 is attached to a side surface of the main beam 210, and at least a portion of the projection of the first beam 223 is disposed on the upper surface of the main beam 210, so that the second beam 224 protrudes out of the side surface of the main beam 210 when being folded on the main beam 210, thereby minimizing the packaging cost and the transportation cost of the main beam 210.

The second bracket 240 is recessed to form a rotating portion 203 for installing the adaptor 202, the auxiliary beam 220 is connected with the main beam 210 through the rotation of the adaptor 202, and the adaptor 202 slightly protrudes out of the side portion of the second bracket 240, so that when the auxiliary beam 220 is folded on the main beam 210, the second beam 224 is attached to the side surface of the main beam 210, and at this time, the overall width of the frame 200 is slightly larger than that of the main beam 210.

When the auxiliary beam 220 is located at the locking position, the auxiliary beam 220 is locked on the electric upright post 300, the auxiliary beam 220 can lock the plugging matching state of the plugging part 340 and the socket part 250 when in the locking position, and the auxiliary beam 220 can be kept at the locking position by locking the auxiliary beam 220 on the electric upright post 300, so that the situation that the electric upright post 300 and the main beam 210 are relatively displaced due to random movement of the auxiliary beam 220 is avoided. Because the main beam 210 extends out of the table 100, the table 100 cannot be effectively supported, after the auxiliary beam 220 and the electric upright 300 are locked, the frame 200 and the electric upright 300 can be in an integrated structure, the structural strength and stability of the table frame are improved, the supporting performance of the table frame to the table 100 is also enhanced, and in the process of connecting the auxiliary beam 220 and the electric upright 300, the electric upright 300 and the main beam 210 are locked and cannot move relatively, so that the connection between the auxiliary beam 220 and the electric upright 300 is smoother.

It will be understood, of course, that the same technical effect may be achieved even if the setting positions of the stopper 350 and the stopper hole 225 are interchanged.
