When the water dispenser is required to be arranged at the activity place of the old people, the number of the water dispenser can be determined according to the number of the old people who move at the activity place, the determined number of the water dispenser can be connected, and then the seat 121, the table 122 and the drinking water module 123 which are matched with the bottom plate 1 are installed on the bottom plate 1.

When several bottom plates 1 are needed to be connected together in sequence, a bottom plate 1 is firstly fixed at the place where the bottom plate 1 needs to be established, then the bottom plate 1 which needs to be connected with the bottom plate is close to the place, and the connecting block 19 on the moving bottom plate 1 is inserted into the sliding groove A2 on the fixed bottom plate 1.

When the connecting block 19 inserted into the slide groove A2 meets the slide block A21 in the slide groove A2, the side end of the moving bottom plate 1 just meets the rack B35 on the fixed bottom plate 1. With the two bottom plates 1 further approaching, the connecting block 19 pushes the slide block A21 in the slide groove A2 to move synchronously, the slide block A21 further compresses the corresponding spring A23, the moving bottom plate 1 presses the rack B35 meeting with the moving bottom plate to contract in the corresponding slide groove B4, and the spring C36 nested on the rack B35 is further compressed. The rack B35 drives the slide bar A28 to retract into the sliding sleeve 24 through a straight gear B34, a shaft sleeve A33, a straight gear A32 and a rack A31. The spring B30 in the sliding sleeve 24 is further compressed, and the spring B30 presses the sliding sleeve 24 tightly against the side of the sliding block a21 with larger elasticity.

As the two bases 119 continue to approach each other, the rack B35 continues to contract into the corresponding sliding groove B4, the spring B30 in the sliding sleeve 24 continues to be further compressed, the connecting block 19 drives the sliding block a21 to continue to contract into the sliding groove a2, the spring a23 continues to be further compressed, and the limiting groove B20 on the connecting block 19 gradually approaches to the end of the inclined surface a25 of the sliding sleeve 24.

When the gap between the two bottom plates 1 is reduced to a certain width, the limit groove B20 on the connecting block 19 meets the inclined surface A25 end of the sliding sleeve 24, and the sliding sleeve 24 is instantly inserted into the limit groove B20 on the connecting block 19 under the action of the corresponding spring B30. The fixture block 38 installed on the sliding sleeve 24 instantly passes over the inclined plane B40 of the sliding rod B39, the restoration of the sliding sleeve 24 is limited by the interaction of the inclined plane B40 end of the sliding rod B39 and the fixture block 38, the inclined plane A25 end of the sliding sleeve 24 is fixedly inserted into the limiting groove B20 on the connecting block 19 to lock the connecting block 19 in the sliding groove A2, and therefore the connection of the two bottom plates 1 is completed.

The end face of the engaging tooth 78 of the clutch pulley 77 mounted on the rotating shaft C74 of the fixed base plate 1 abuts against the end face of the engaging tooth 78 of the clutch pulley 77 mounted on the rotating shaft C74 of the moving base plate 1.

When the two base plates 1 approach each other, the two clutch wheels 77 on the two base plates 1 press against each other, the two clutch wheels 77 press against each other to drive the corresponding rotating shaft C74 to contract towards the corresponding rotating shaft B71, and the spring F76 in the rotating shaft B71 is further compressed.

If the teeth 78 on the two clutch wheels 77 are just engaged, this indicates that the connection of the movement synchronization mechanism 124 and the connection locking mechanism 50 on the two base plates 1 is finished. If the end surfaces of the biting teeth 78 of the two clutch wheels 77 are abutted and are not meshed, because the inclined surface A25 of the sliding sleeve 24 is at a certain distance from the edge of the notch of the limiting groove B20 on the connecting block 19 inserted into the sliding groove A2, the wheel shaft 62 is driven by the wheel 63 on the moving base plate 1 to rotate by slightly pulling the moving base plate 1 in the direction away from the fixed base plate 1, the wheel shaft 62 is driven by the wheel shaft 62, the wheel shaft 62 drives the clutch wheel 77 mounted on the rotating shaft C74 to rotate for a certain angle through the corresponding bevel gear A64, the bevel gear B65, the rotating shaft A66, the straight gear G68, the straight gear H69, the one-way ring 70, the rotating shaft B71 and the rotating shaft C74, the biting teeth 78 on the two abutted clutch wheels 77 are staggered, and are meshed with each other under the action of the spring F76 in the rotating shaft B71, so. At this point, the connection of the movement synchronization mechanisms 124 of the two base plates 1 is ended. At this time, the sliding rails 83 on two adjacent bottom plates 1 are butted one by one.

During the process that the two base plates 1 approach each other, the wheels 63 in the moving base plate 1 drive the wheel shafts 62 to rotate, and the wheel shafts 62 cannot drive the clutch wheel 77 arranged on the rotating shaft C74 to rotate through the corresponding bevel gear A64, bevel gear B65, rotating shaft A66, straight gear G68, straight gear H69, one-way ring 70 playing an overrunning role at this time, rotating shaft B71 and rotating shaft C74.
