Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses a stretching table, including four group's supporting legs 1, the one end of four group's supporting legs 1 is fixed with bearing frame 2, is equipped with desktop board 3 on the bearing frame 2, and desktop board 3 is fixed with bearing frame 2. The two sides of the table top plate 3 are provided with extending plates 31, the extending plates 31 are movably abutted against the table top plate 3, and the two groups of extending plates 31 and the table top plate 3 are arranged in a circular shape in cross section, thereby forming a round table.

Bearing frame 2 is "mesh" font setting, and bearing frame 2 includes bearing board 21 and two sets of backup pad 22 that the symmetry set up that two sets of symmetries set up, and through-hole 221 has been seted up to the side that backup pad 22 contradicted with desktop board 3, and extension board 31 passes through-hole 221 and arranges in bearing frame 2, realizes accomodating extension board 31. The supporting plate 22 is hinged with the cover plate 9 through the hinge, the cover plate 9 is used for covering the through hole 221, and when the extension plate 31 is arranged in the bearing frame 2, the cover plate 9 is used for covering the through hole 221, so that the stretching table is more attractive. The bearing plate 21 is provided with a slide rail 4, the slide rail 4 is provided with a slide groove 41, the slide groove 41 is arranged in a long strip shape, and the slide block 5 is arranged in the slide groove 41 so that the slide block 5 can slide back and forth along the length direction of the slide groove 41. The two sides of the sliding block 5 are provided with rollers which are abutted against the groove wall of the sliding groove 41, so that the sliding friction between the sliding block 5 and the sliding groove 41 is changed into rolling friction, and the sliding block 5 can conveniently slide in the sliding groove 41. Two ends of the sliding block 5 are hinged with two groups of supporting rods 6, the supporting rods 6 are positioned on the surface of the sliding block 5 away from the bottom of the sliding groove 41, one end of each supporting rod 6 away from the sliding block 5 is hinged with a supporting frame 7, and the supporting frame 7 is fixed with one surface of the extending plate 31 so that the supporting rods 6 can support the extending plate 31; slider 5 is equipped with reset spring 8, and reset spring 8 is located slider 5 and keeps away from the surface of 41 tank bottoms of spout, and reset spring 8 is located between two sets of bracing pieces 6, and the one end that slider 5 was kept away from to reset spring 8 and support frame 7 are kept away from the one end of slider 5 fixed to reset spring 8 pulls extension board 31.

The implementation principle of the embodiment is as follows: when the surface area of the desktop of the stretching desk needs to be increased, the extension plate 31 is pulled out from the bearing frame 2, the sliding blocks 5 slide towards the two sides of the desktop plate 3 on the sliding rails 4, so that the extension plate 31 extends out of the bearing frame 2, and one surface of the extension plate 31 and the surface of the desktop plate 3 are on the same plane, so that the area of the desktop is increased, and the desktop is convenient to use; at this time, the return spring 8 is in a stretched state, so that the two sets of support plates 22 support the extension plate 31 through the support frame 7, and the side surface of the extension plate 31 is abutted against the side surface of the table top 3. When the surface area of the desktop of the stretching desk needs to be reduced, the extension plate 31 is pulled, so that a gap is formed between the extension plate 31 and the desktop plate 3, the extension plate 31 is slightly pressed downwards, and the reset spring 8 is in a stretching state, so that the reset spring 8 always has a restoring force, the extension plate 31 is conveniently pulled into the through hole 221, the extension plate 31 placed in the through hole 221 is pushed into the bearing frame 2 by hands, and the area of the desktop is reduced, so that the extension plate is convenient to store. The utility model has the advantages of scientific and reasonable design, simple structure, the size of desktop can be adjusted to tensile table, facilitates the use and accomodates.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
