DETAILED DESCRIPTION

[0026] The specific embodiments of the utility model will be described in further detail below with reference to the drawings. The following examples are used to illustrate the utility model, but are not used to limit the scope of the utility model.

[0027] Please see Figure 1 And Figure 2 The embodiment provides a folding table with a hidden table top, comprising a table frame 1, a support frame 2 and a cantilever 3, the support frame 2 is provided with a first track 101 along the vertical lifting direction of the table frame 1, the bottom of the table frame 1 is provided with a first wheel shaft 102 matched with the first track 101, the side of the table frame 1 is provided with a second track 201 along the horizontal stretching direction of the table frame 1, one end of the cantilever 3 is provided with a second wheel shaft 202 matched with the second track 201, and the other end of the cantilever 3 is connected with the support frame 2 in a rotating mode.

[0028] Specifically, the support frame 2 is installed in the carriage through mounting bolts 9, so that the whole folding table is fixed to the side wall of the carriage. The cantilever 3 is connected with the support frame 2 through a cantilever rotating shaft 6, the cantilever 3 is provided with a buckle 7, and the support frame 2 is provided with a limiting sliding groove 8 matched with the buckle 7. The limiting sliding groove 8 is an arched sliding groove, and the arching direction of the arched sliding groove is the upward direction of the table frame. When the cantilever 3 rotates relative to the support frame 2 through the cantilever rotating shaft 6, the table frame 1 moves up and down in the vertical direction through the first track 101, and simultaneously stretches in the horizontal direction through the second track 201.

[0029] Among them, the first track 101 is a rack symmetrically arranged on both sides of the support frame 2, the first wheel shaft 102 is a gear meshing with the two racks, respectively, a damper 4 is installed at the bottom of the table frame 1, and the damper 4 is connected with the two gears. A power-assisted torsional spring 5 is installed at the bottom of the table frame 1, and the power-assisted torsional spring 5 is connected with the two gears. At this point, the damper 4 can be a one-way damper, which increases the damping force value when the table frame 1 vertically falls down; the damper 4 can also be a two-way damper, which increases the damping force value when the table frame 1 vertically falls down and horizontally lays down. The power-assisted torsional spring 5 stores power when the table frame 1 vertically rises, so as to reduce the force exerted by the user. The second track 201 is a slide rail symmetrically arranged on both sides of the table frame 1, and the second wheel shaft 202 is a pulley matched with the two slide rails, respectively.

[0030] In combination with Figures 3a to 3d A table board is installed on the table frame 1, and the outer side of the table board when being retracted is a reverse side, and the reverse side of the table board is provided with a handle m. The table board is a folding table board, and a folding part n of the table board is opened and closed along the horizontal stretching direction of the table board.

[0031] Working principle:

[0032] The folding table with a hidden table board provided by the embodiment is used, one hand holds the handle m, the table board is pulled out, the buckle 7 reaches the limiting position of the limiting sliding groove 8, the table board is lifted upward, the table board gradually becomes horizontal under the constraint of the first track 101 and the second track 102, the folding part n of the table board is opened, and the table board is completely unfolded. When the table board needs to be stored, the folding part n of the table board is retracted, the handle m is held, the table board is pushed to the direction of the table frame 1, the table board gradually becomes vertical under the constraint of the first track 101 and the second track 102, the table board is pushed inward, the buckle 7 returns to the initial position of the limiting sliding groove 8, and the table board is completely hidden in the compartment side wall, and the storage is completed.

[0033] The above only describes the preferred embodiments of the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
