As shown in fig. 1, the present invention provides a leg assembly 100, the leg assembly 100 being adjustable in height. The leg assembly 100 can connect a raised floor and a ground or foundation surface (not shown) together so that the ground or foundation surface can stably support the raised floor, and the leg assembly 100 can adjust the height, thereby adjusting the height of the raised floor. Of course, the ground or foundation surface may also be connected to a floor, with the leg assembly 100 connecting the raised floor and the floor together. Raised floors can be made of steel floors or calcium sulfate floors. For example, raised floors may be applied to shipping containers, which may be used in data centers. For example, a raised floor and leg assembly 100 may be provided between two containers placed side-by-side.

Specifically, the leg assembly 100 includes a support member 110, a leg 130, and a connection member 150, the support member 110 being used to support a raised floor, and the connection member 150 being used to connect a floor. The support member 110 may be configured as a hollow structure, for example, the support member 110 may be configured as a rectangular tube. Of course, the support member 110 may also be configured as a channel, which is not intended to be limiting in this embodiment.

The support member 110 includes a support hole 111 for connection with the leg 130. More specifically, as shown in connection with fig. 3, the support member 110 includes a first wall 112 and a second wall 113 that are opposed, and the first wall 112 and the second wall 113 may be oppositely disposed in a height direction of the support member 110. The height direction of the support member 110 is parallel to the axial direction of the support hole 111. The first wall 112 is located above the second wall 113 in the height direction of the support member 110.

Further, the second wall 113 has a support hole 111. The support hole 111 has an internal thread and the leg 130 has an external thread. The cross-sectional shape of the support hole 111 may be configured to be circular, and the cross-sectional shape of the leg 130 may be configured to be circular. In the present embodiment, the cross-section is perpendicular to the central axis of the support hole 111. The external threads of the leg 130 are engaged with the internal threads of the support member 110, i.e., the external threads of the leg 130 are engaged with the internal threads of the support hole 111. Thereby, the leg 130 can rotate relative to the support member 110, thereby moving the support member 110 up and down in the height direction of the support member 110.

Further, the first wall 112 of the support member 110 has a through hole 114, and the through hole 114 is disposed opposite to the support hole 111. The through-hole 114 of the first wall 112 and the support hole 111 of the second wall 113 are oppositely arranged in the height direction of the support member 110. Preferably, the through hole 114 is coaxially disposed with the support hole 111. Of course, the raised floor may be provided with floor holes disposed opposite to the through holes 114 in the height direction of the support member 110. The first operating member 200 can extend through the floor hole and the through hole 114.

The first operating member 200 is used to rotate the leg 130. The first operating member 200 may be moved in the height direction of the support member 110. The first operating member 200 moves downward from above the support member 110 and passes through the through hole 114 to be connected with the leg 130. The first operating member 200 is moved upward from the inside of the support member 110 to be separated from the leg. Further, the leg 130 further includes a catching portion 133, and the catching portion 133 may be connected with the first operating member 200. The engaging portion 133 includes an engaging hole 137. The first operating member 200 can be engaged with the engaging hole 137, and the first operating member 200 rotates to drive the supporting leg 130 to rotate, so that the supporting member 110 can move relative to the supporting leg 130.

The external threads of the leg 130 engage the internal threads of the support member 110 and rotation of the leg 130 enables linear movement of the support member 110 relative to the leg 130. The leg 130 is movable from the inside of the support member 110 toward the outside of the support member 110, and the leg 130 is also movable from the outside of the support member 110 toward the inside of the support member 110 to adjust the length of the protruding support member 110 of the leg 130, thereby moving the support member 110 and thus adjusting the position of the support member 110.

Specifically, the leg 130 may be rotated in a clockwise direction, and the support member 110 is moved upward in the height direction of the support member 110, enabling an extending action of the leg 130 with respect to the support member 110 to raise the height of the support member 110, thereby raising the height of the raised floor. The legs 130 may also be rotated in a counter-clockwise direction and the support member 110 moved downward in the height direction of the support member 110, effecting a retracting action of the legs 130 to lower the height of the support member 110 and thus the raised floor. Of course, the leg 130 may be rotated in a counterclockwise direction to achieve extension and the leg 130 may be rotated in a clockwise direction to achieve retraction, which is not intended to be limiting in this embodiment.

Further, in order to connect the leg 130 with the bottom plate, the leg 130 may be configured to be hollow, and the leg 130 further includes an inner passage 132 and a connection hole 131, the connection hole 131 being located at a bottom end of the inner passage 132 in a height direction of the support member 110. The connection hole 131 communicates with the inner passage 132. The connecting member 150 is located in the internal passage 132, and at least a portion of the connecting member 150 extends downward beyond the connecting hole 131. The connecting member 150 is connected to both the leg 130 and the base plate. Thus, the leg assembly 100 can be applied to a structure with a low overhead height, such as an overhead height of 80-100 mm.

The connector may be a screw, and the screw may be connected with the base plate to fix the leg 130 and the support member 110 to the base plate, and the lower surface of the leg 130 is closely attached with the upper surface of the base plate, so that the base plate can stably support the leg 130 and the support member 110. Of course, the screw may be separated from the bottom plate, thereby enabling the leg 130 to rotate relative to the support member 110, thereby enabling the support member 110 to move in the height direction of the support member 110 relative to the leg 130, and thus adjusting the height of the support member 110.

Further, at least a portion of the legs 130 are located inside the support member 110. At least a portion of the leg 130 is positioned between the first wall 112 and the second wall 113. Preferably, the engaging portion 133 may be located between the first wall 112 and the second wall 113. Thus, the space between the engaging portion 133 and the first wall 112 can be reduced, and the space between the first wall 112 and the second wall 113 can be fully utilized. The engaging hole 137 is disposed opposite to the through hole 114 to prevent the engaging hole 137 and the through hole 114 from being deviated, ensuring that the first operating member 200 can be accurately connected with the engaging hole 137.

Further, a portion of the interior channel 132 of the leg 130 is located between the first wall 112 and the second wall 113. In this way, the support member 110 can receive a portion of the leg 130, enabling extension and retraction of the leg 130. The connecting member 150 is positioned in the internal channel 132 and the connecting member 150 is connected to the leg 130 to form a unitary structure, reducing the length of the leg assembly 100 in the height direction of the support member 110, saving space, and facilitating the connection of the raised floor and the floor together.

As shown in fig. 2, the inner passage 132 has engaging portions 133 and connecting holes 131 at both ends thereof. The engaging portion 133 is located above the connection hole 131 in the height direction of the support member 110. The engaging portion 133 is located above the connecting member 150 in the height direction of the support member 110, facilitating the first operating member 200 to rotate the leg 130. The height direction of the support member 110 is parallel to the height direction of the leg 130.

The cross-sectional shape of the internal passage 132 may be configured as a circle. The size of the inner passage 132 in the radial direction of the connection hole 131 is larger than that of the connection hole 131. The axial direction of the connection hole 131 is parallel to the height direction of the support member 110. Thus, a stepped structure 134 can be formed between the inner passage 132 and the connection hole 131 to limit the connection member 150.

The connecting member 150 includes a head portion 151 and a tail portion 152, and the head portion 151 and the tail portion 152 are connected. The size of the head 151 in the radial direction of the coupling hole 131 is greater than that of the tail 152 and smaller than that of the inner passage 132. The head 151 is located inside the internal passage 132. The size of the tail portion 152 in the radial direction of the connection hole 131 may match the size of the connection hole 131. The tail portion 152 may extend through the connection hole 131.

Preferably, the tail 152 extends at least partially downward beyond the leg 130. Thereby enabling connection with the backplane. The size of the head portion 151 in the radial direction of the coupling hole 131 is larger than that of the coupling hole 131, so that the head portion 151 does not extend beyond the coupling hole 131. The head 151 abuts against the step 134, so that the step 134 can prevent the head 151 from entering the connection hole 131, prevent the connection member 150 from falling out of the connection hole 131, and limit the connection member 150 by the step 134.

The first operating member 200 may be configured as a hexagon wrench, and the cross-sectional shape of the engagement hole 137 may be configured as a hexagon so as to match the first operating member 200. Of course, the cross-sectional shapes of the engaging portion 133 and the first operating member 200 may be pentagonal, quadrangular, or straight, and the like, and this embodiment is not intended to limit this. The dimension of the inner passage 132 in the radial direction of the connection hole 131 is smaller than the dimension of the click hole 137. Thus, the top of the internal channel 132 can abut against the bottom of the first operating member 200, ensuring that the first operating member 200 and the engaging portion 133 are engaged together.

As shown in fig. 2, the leg 130 further includes an engagement portion 135 and a support portion 136, and the support portion 136 is connected to the engagement portion 135. The support portion 136 is located below the engagement portion 135 in the height direction of the support member 110. The engagement portion 135 has an external thread. The engagement portion 135 may be coupled with the support hole 111.

In order to enable the leg 130 to stably support the support member 110, the dimension of the support portion 136 in the radial direction of the support hole 111 is larger than the dimension of the engagement portion 135. Thus, the support portion 136 has a sufficient contact area with the base plate, thereby stably supporting the engagement portion 135. Alternatively, the cross-sectional shape of the support portion 136 may be hexagonal to conform to the shape of the first operating member 200, thereby reminding the model of the first operating member 200.

Further, the support assembly further includes a fastening member 160, and the fastening member 160 is connected with the support member 110. Alternatively, the fastening member 160 may be connected to the lower surface of the support member 110 by welding. The fastening member 160 includes a fastening hole 161, and the fastening hole 161 has an internal thread. Alternatively, the fastening member 160 may be configured as a nut to facilitate manufacturing.

The legs 130 engage with the fastening holes 161. The fastening hole 161 may be coaxially disposed with the support hole 111. In this way, the leg 130 is engaged with both the support hole 111 and the fastening hole 161 to secure the strength of the support to the support member 110. The leg 130 extends at least partially downward beyond the fastening member 160, whereby the fastening member 160 does not interfere with the movement of the leg 130 in the height direction of the support member 110, so that the leg 130 can adjust the height at which the support member 110 is located.

The leg 130 is screw-coupled with both the support hole 111 of the support member 110 and the fastening hole 161 of the fastening member 160. The first operating member 200 rotates the leg 130 to move the support member 110 to a desired height, such as the first wall 112. The connection member 150 enters the internal passage 132 through the through hole 114 and the engaging portion 133 in the height direction of the support member 110. The second operating member rotates the connecting member 150 such that the tail portion 152 of the connecting member 150 is connected with the base plate and the head portion 151 of the connecting member 150 abuts against the stepped structure 134. In this manner, the entire adjustable height leg assembly 100 is secured to the floor.

When the leg assembly 100 requires height adjustment, the second operating member first releases the connecting member 150, so that the connecting member 150 is separated from the bottom plate. The first operating member 200 rotates the leg 130 so that the support member 110 moves to a desired height. The second operating member in turn secures the connecting member 150 to the base plate.
