In the technical solution, as shown in fig. 2, the stretching table mechanism with stretchable two sides of the present invention is provided. The number of the moving blocks 22 and the number of the moving guide rail blocks 23 are two, the two moving blocks 22 are slidably disposed on the fixed chute block 21, and the two moving guide rail blocks 23 are disposed in one-to-one correspondence with the two moving blocks 22. The structure is designed to enable the two movable guide rail blocks 23 to realize relative movement between the fixed chute block 21 and the fixed guide rail block 24, so that the two sides of the table frame 1 can be stretched.

Preferably, the stretching mechanism 2 further comprises an angle code connecting piece 25, one end of the angle code connecting piece 25 is connected with the fixed sliding groove block 21, and the other end of the angle code connecting piece 25 is connected with the fixed guide rail block 24. The corner connector 25 is used to fixedly connect the fixed chute block 21 and the fixed guide block 24 together, so that the movable guide block 23 can be stably moved between the fixed chute block 21 and the fixed guide block 24.

In this technical solution, a lifting guide groove 222 is formed at the bottom of the movable guide block 23, a lifting guide 223 is slidably disposed in the lifting guide groove 222, and one end of the lifting guide 223 protrudes out of the lifting guide groove 222 and is connected to the movable block 22. Specifically, the lifting guide groove 222 is a waist-shaped groove. During the lifting process of the movable guide block 23, the first guide slider 232 at one end of the movable guide block 23 is lifted along the vertical section 243, and the other end of the movable guide block 23 is lifted under the matching guidance of the lifting guide groove 222 and the lifting guide 223. The design of the structure enables both ends of the movable guide rail block 23 to be guided in an auxiliary manner, so that the movable guide rail block 23 can be lifted smoothly and stably.

In the present technical solution, a pulley 211 is disposed on one side of the fixed sliding block 21 close to the moving block 22, and a sliding groove 212 engaged with the pulley 211 is disposed on one side of the moving block 22 close to the fixed sliding block 21.

Therefore, in this embodiment, the lifting guide 223 is sleeved with a spring 27 and a pad 26, and when the moving guide block 23 is at the lowest position, the pad 26 compresses the spring 27, so that the spring 27 is in a state of storing elastic potential energy; when the movable rail block 23 ascends, the spring 27 releases elastic potential energy to generate upward elastic force to the gasket 26 and the movable rail block 23, and the elastic force helps to provide auxiliary power for the ascending of the movable rail block 23, so that the ascending of the movable rail block 23 is smoother and saves power.

The utility model also provides a stretching table, which comprises the stretching table mechanism, a fixed table top 4 and a movable table top 5, wherein the two sides of the table frame 1 are provided with supporting blocks for supporting the fixed table top 4, and the fixed table top 4 is positioned above the fixed guide rail block 24 and the fixed sliding chute block 21; the two sides of the movable table top 5 are respectively connected with the two movable guide rail blocks 23 of the two stretching mechanisms 2. Fig. 11 shows a stretching table with a single side movable table top 5; figures 12 and 13 illustrate an extended table with a double sided activity table top 5.

The working process of stretching the table comprises the following steps:

a stretching table lifting step: the two movable table tops 5 are respectively pulled out from the left side and the right side of the fixed table top 4, after the two movable table tops 5 are stretched to the right position (i.e. the first slide guide 232 moves to the joint of the transverse section 242 and the vertical section 243), the movable table tops 5 are continuously pulled, at this time, the second slide guide 221 slides along the oblique line section 233 of the oblique guide slot 231 and drives the movable guide rail block 23 and the first slide guide to ascend along the vertical section 243 of the guide rail slot 241, and the ascending movable guide rail block 23 drives the movable table top 5 to ascend, so that the table top of the movable table top 5 is flush with the table top of the fixed table top 4.

A stretching table recovery step: the two movable table tops 5 are respectively pushed towards the fixed table top 4, when the movable table top starts to be pushed, the movable guide rail block 23 descends under the matching action of the second guide slide piece 221 and the oblique line section 233 of the oblique guide groove 231, and meanwhile, the movable guide rail block 23 drives the first guide slide piece to descend along the vertical section 243 of the guide rail groove 241; when the movable table top 5 descends to a certain position (i.e. the first sliding guide piece 232 descends to the joint of the transverse section 242 and the vertical section 243), the movable table top 5 is continuously pushed, the movable table top 5 drives the movable guide rail block 23 together with the first sliding guide piece 232 to move to the position of the table frame 1 along the transverse section 242 of the guide rail slot 241, and at this time, the movable table top 5 is recovered to the position between the fixed table top 4 and the table frame 1, so that the movable table top 5 is stored.
