[0036] like Figure 1 - Figure 8 As shown, a training table suitable for movement and folding in an embodiment of the present invention comprises a table top 3, a pair of first table legs 11 and a pair of second table legs 12 arranged diagonally are provided at the bottom of the table top 3, a sliding unit connecting the first table leg 11 and the second table leg 12 on the same side, and a rotating unit connecting the first table leg 11 and the second table leg 12 on the same side; the two ends of the rotating unit respectively drive the first table leg 11 and the second table leg 12 to rotate, so that the first table leg 11 and the second table leg 12 on the same side rotate relative to the table top 3; and also includes a locking device for locking and fixing the first table leg 11 and the second table leg 12 so that the first table leg 11 and the second table leg 12 support the table top 3; the sliding unit drives the first table leg 11 and the second table leg 12 to slide, so that the first table leg 11 and the second table leg 12 are staggered after folding, so that the rotating unit can drive the first table leg 11 and the second table leg 12 to rotate and fit the bottom surface of the table top.

[0037] The first table leg 11 is rotatable and slidable relative to the table top, and the second table leg 12 is rotatable relative to the table top, and the first table leg 11 can drive the second table leg 12 to slide relative to the table top 3 while sliding. When folding, the first table leg 11 arranged diagonally is pushed to slide and rotate by manual thrust, and the first table leg 11 drives the second table leg 12 located on the same side to slide and rotate synchronously, so that the first table leg 11 and the second table leg 12 on both sides are respectively moved outward (specifically, Figure 3 The first table leg 11 and the second table leg 12 are folded in the same plane, which saves space and facilitates the stacking and movement of a large number of training tables. When the mobile and foldable training table is opened, the first table leg 11 is pushed to slide and rotate by manual thrust. While the first table leg 11 slides and rotates, it drives the second table leg 12 to slide and rotate synchronously, so that the first table leg 11 and the second table leg 12 on both sides are respectively moved inward (specifically, Figure 5 The table top is slid by a distance greater than the radius of the table leg (in the direction indicated by the arrow parallel to the table top as shown in the figure), so that the first table leg 11 and the second table leg 12 are simultaneously subjected to the reaction force from the elastic member 7, so that the first table leg 11 and the second table leg 12 can stably support the table top at four points.

[0038] like Figure 1 As shown, the rotating unit includes: a fixed clamp 4 and a rotating member 5; the rotating member 5 is fixed to the table top 3 and can be fixed by screws, and the fixed clamp 4 is engaged with the rotating member 5; the sliding unit includes: a first rod 1, an elastic member 7, a connecting member 6 and a second rod 2, wherein, as Figure 2 As shown, one rotating unit is used to install the ends of the first rod 1 and the second rod 2, and the other rotating unit is installed on the second rod 2. The rotating member 5 is preferably a coupling kit. Preferably, the fixed clamp 4 and the rotating member 5 are provided with the same taper inside, so that the fixed clamp 4 can be completely locked after entering the rotating member 5, and will not be affected by the installation clearance problem between the first rod 1 or the second rod 2 and the rotating member 5. Optionally, matching concave-convex grooves are provided in the fixed clamp 4 and the rotating member 5, and the concave-convex grooves can be claw-shaped structures or any other structures that can match each other.

[0039] One end of the first rod 1 is connected to the first table leg 11. The first rod 1 and the first table leg 11 can be welded and fixed, or can be integrally formed, and the first table leg 11 and the first rod 1 are perpendicular to each other; the other end of the first rod 1 is inserted into a rotating unit, so that the first rod 1 drives the first table leg 11 to rotate and slide relative to the table top 3. One end of the second rod 2 is connected to the second table leg 12, and the other end of the second rod 2 passes through another rotating unit and is inserted into the rotating unit connected to the first rod, so that the second rod 2 drives the second table leg 12 to rotate relative to the table top 3, and an elastic member 7 is installed at the end of the second rod 2 inserted into the rotating unit; one end of the elastic member 7 is inserted into the rotating unit connected to the first rod 1, and the other end of the elastic member 7 is connected to the connecting member 6, and the connecting member 6 is sleeved on the second rod 2 and fixed to the table top 3, for example, it can be connected to the table top 3 by screws, and the first rod 1 and the second rod 2 can be coaxially installed by fixing the connecting member 6, and the elastic member 7 is preferably a spring, and the compression of the spring can apply a reverse force to the rotating member 5 and the connecting member 6. Specifically, before the connecting member 6 is fixed to the table top 3, the spring is compressed between the rotating member 5 and the connecting member 6.

[0040] In an optional embodiment, the locking device includes a first locking device 9 and a second locking device 10 that are fixed by snapping, and the first locking device 9 and the second locking device 10 are respectively provided with corresponding concave-convex grooves, and the concave-convex grooves can be claw-shaped structures or any other structures that can match each other. Among them, the first locking device 9 and the second locking device 10 can be sleeved on the second rod 2, and the second locking device 10 is fixed to the desktop 3 by screws, and the first locking device 9 is fixed to the second locking device 10 by the engagement of the concave-convex grooves.

[0041] Optionally, both the fixed clamp 4 and the rotating member 5 are provided with limit members, and the limit members are used to limit the rotation angle of the first rod 1 so that the first table leg 11 cannot continue to rotate when it rotates to a position perpendicular to the table top 3.

[0042] Optionally, a sleeve is provided at the end of the rotating member 5 of the rotating unit inserted into the first rod 1, and the sleeve is inserted into the end of the second rod 2, so that the second rod 2 can be driven to rotate synchronously when the first rod 1 rotates, and the second rod 2 can be driven to move synchronously when the first rod 1 moves. Therefore, when the first table leg 11 is manually rotated and slid, the second table leg 12 can be driven to rotate and slide synchronously, and the first rod 1 and the second rod 2 can maintain coaxial rotation through the provided connecting member 6.

[0043] In an optional embodiment, the movable and foldable training table further comprises: a crossbeam 8, and two ends of the crossbeam 8 are respectively connected to a sliding unit or a rotating unit. Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, the cross beams 8 may be two cross beams 8 that are arranged opposite to each other, and both ends of each cross beam 8 are connected to the sliding unit or the rotating unit. The cross beams 8 may be used to reinforce the installation and fixation of the sliding unit or the rotating unit on the desktop 3 .

[0044] Furthermore, the sliding unit is provided with a connecting plug, which is used to install the end of the cross beam 8. Preferably, the connecting plug is provided on the rotating member 5 of the rotating unit. During construction, after installing the rotating member 5, the end of the cross beam 8 is inserted into the connecting plug so that the whole is in a clamped state.

[0045] Furthermore, a baffle 13 is provided on the side of the rotating member 5 , and a groove is provided on the baffle 13 , and the end of the crossbeam 8 is placed in the groove.

[0046] like Fig. 9As shown, in an optional embodiment, the movable and foldable training table further includes a protective cover 14, which is mounted on the desktop 3 and is fixed to the desktop 3 by welding or connected with screws. The protective cover 14 covers the sliding unit and the rotating unit to effectively protect them from dust intrusion, so as to prevent dust from intrusion and affecting use or cleaning dust to cause damage to the mechanism. Preferably, the protective cover 14 covers the elastic member 7 and the connecting member 6.

[0047] like Fig.10 As shown, when the movable and foldable training table is in a folded state, the foldable table can be placed flat on a cart 15 with rollers at the bottom, so that multiple training tables can be transported to the place of use at the same time to meet the needs of modern mobile office. In addition, multiple training tables can also be stacked to facilitate the storage of the training tables and save space.

[0048] The working process of the present invention is described below as follows:

[0049] When the movable and foldable training table needs to be opened, the first table leg 11 is rotated, and the first table leg 11 can drive the second table leg 12 to rotate synchronously in the rotating member 5. At this time, the fixed clamp 4 and the rotating member 5 are in a separated state, and the first locking device 9 and the second locking device 10 are also in a separated state. The first table leg 11 and the second table leg 12 are not subject to the tightening constraint force and can rotate smoothly; when the first table leg 11 and the second table leg 12 are rotated to a position perpendicular to the table top 3, they are restricted by the limit members set on the fixed clamp 4 and the rotating member 5, and the first table leg 11 and the second table leg 12 cannot continue to rotate. At this time, they are only subject to the reverse thrust applied by the spring compression. Push the first table leg 11 so that the first table leg 11 slides relative to the table top 3. While sliding, the first table leg 11 drives the second table leg 12 located on the same side to slide relative to the table top. After sliding for a distance greater than at least the radius of the table leg, the sliding stops. The fixing clamp 4 is inserted into the rotating member 5 , and the first locking device 9 and the second locking device 10 are engaged with each other, so that the first table leg 11 and the second table leg 12 are locked and fixed to support the table top 3 .

[0050] When the movable and foldable training table needs to be folded, the first locking device 9 and the second locking device 10 are separated, the first table leg 11 and the second table leg 12 are released, and the first table leg 11 is manually pulled outward to separate the fixing clamp 4 from the rotating member 5, and the first table leg 11 is rotated, and the second table leg 12 is driven to rotate synchronously through the first table leg 11; the first table leg 11 and the second table leg 12 are rotated to fit onto the table top 3 to complete the folding of the training table.

[0051] In summary, the embodiments of the present invention provide a movable and foldable training table, which has a simple folding mechanism and meets the requirements of aesthetics while meeting the convenience of operation, saving space, and when a large number of training tables are needed in a training venue, the movable and foldable training table of the present invention can be used to transport multiple training tables at one time, thereby improving work efficiency.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
