Detailed Description

The first embodiment is as follows:

referring to fig. 1 to 5, a folding desk includes a desk board 10, two outer legs 20 symmetrically disposed at left and right sides of the desk board, and two inner legs 40 symmetrically disposed at left and right sides of the desk board, wherein an outer leg link 30 is connected between upper ends of the two outer legs, and an inner leg link 50 is connected between upper ends of the two inner legs. The outer leg 20 and the inner leg 40 on the same side are rotatably hinged together in an X-configuration, the hinge point of rotation being indicated by the letter O. The table plate 10 is positioned between the two outer legs 20, the rear end parts of the side edges of the table plate are hinged with the outer legs in a rotating mode, a buckle 60 is arranged at the front end part of the bottom surface of the table plate 10, and the buckle 60 is arranged corresponding to the inner leg connecting rod 50 and used for being connected with the inner legs in a clamping mode when the folding desk is unfolded to be used. The outer leg 20 or the inner leg 40 can be extended and retracted, and the table plate 10 can be horizontally placed or switched to be placed in a front-low and back-high mode.

When the desk plate is used, the front end of the desk plate 10 is turned outwards and upwards, and the inner side leg 40 is opened and is buckled with the buckle 60. When collapsed, the inner leg 40 nests into the outer leg 20 and the table 10 is stacked on top of the inner leg 40.

In this embodiment, the inner leg 40 is retractable and the inner leg 40 is a portion above the hinge point O, the table 10 is horizontally placed in a fully extended state of the inner leg 40 (as shown in fig. 2), and the table is placed in a low front and high back position after the inner leg 40 is shortened (as shown in fig. 4 and 5). It will be appreciated that shortening of the inner leg 40 will be understood to mean that the height of the front end of the table 10 is reduced.

In this embodiment, the flexible structure of inboard leg adopts the mode of interior outer tube grafting to including the outer tube sets up locating hole and elasticity bulb respectively, utilize the location of grafting that elasticity bulb and locating hole realize length, the locating hole can have a plurality ofly, realizes the adjustment of a plurality of gears. The fully extended state of the inner leg 40 means that the inner leg extends to the longest, different lengths can be adjusted by inserting the elastic ball head into different positioning holes, and the length of the inner leg 40 in fig. 5 is smaller than that in fig. 4.

Preferably, the clip 60 is a C-shaped clip. In addition, a barrier strip 11 is arranged at the front end of the top surface of the table plate 10.

Example two:

referring to fig. 6 to 8, the difference between the second embodiment and the first embodiment is: the inner leg 40 is retractable at a portion below the hinge point O, the table 10 is horizontally disposed (as shown in fig. 6) in a fully retracted state of the inner leg 40, and the table 10 is vertically disposed (as shown in fig. 7 and 8) after the inner leg 40 is extended.

In this embodiment, the fully contracted state of the inner leg 40 means that the inner leg is contracted to the shortest, and the length of the inner leg 40 in fig. 7 is greater than that in fig. 6, and the length of the inner leg 40 in fig. 8 is greater than that in fig. 7, because the elastic ball head is inserted into different positioning holes, different lengths can be adjusted. It is understood that the extension of the inner leg 40 is understood as the clockwise rotation of the table 10 about the rotation hinge point O.

Example three:

referring to fig. 9 to 11, a difference between the third embodiment and the first embodiment is: the outer leg 20 is retractable, the outer leg 20 is partially retractable above the hinge point O, the table 10 is horizontally disposed (as shown in fig. 9) when the outer leg 20 is fully retracted, and the table is horizontally disposed (as shown in fig. 10 and 11) when the outer leg is extended.

In this embodiment, the fully contracted state of the outer leg 20 means that the outer leg is contracted to the shortest, and the elastic ball is inserted into different positioning holes, so that different lengths can be adjusted, wherein the length of the middle and outer leg 20 in fig. 10 is greater than that of the middle and outer leg in fig. 9, and the length of the outer leg 20 in fig. 11 is greater than that of the middle and outer leg in fig. 10. It will be appreciated that extension of the outer leg 20 will be understood to mean elevation of the rear end of the table 10.

Example four:

referring to fig. 12 to 14, the difference between the fourth embodiment and the first embodiment is: the outer legs 20 are retractable, the outer legs 20 are retractable at portions below the hinge points O, the table 10 is horizontally placed in a state where the outer legs 20 are fully extended (as shown in fig. 12), and the table is placed in a low front and high back position after the outer legs 20 are shortened (as shown in fig. 13 and 14).

In this embodiment, the fully extended state of the outer leg 20 means that the outer leg extends the longest, and the length of the outer leg 20 in fig. 13 is smaller than that of the middle and outer legs in fig. 12, and the length of the middle and outer legs 20 in fig. 14 is smaller than that of the middle and outer legs in fig. 13, so that the length of the elastic ball head is inserted into different positioning holes. It will be appreciated that shortening of the outboard leg 20 is understood to mean clockwise rotation of the table 10 about the pivot point O.

Example five:

referring to fig. 15 to 18, a difference between the fifth embodiment and the first embodiment is: the folding desk further comprises a tensioning part 70, wherein two ends of the tensioning part 70 are respectively connected with the part of the inner leg 40 above the rotating hinge point O and the part of the outer leg 20 above the rotating hinge point O, and the tensioning part 70 is in a tensioning state when the folding desk is unfolded for use and is used for pulling the inner leg 40 so that the inner leg connecting rod 50 is supported at a front position below the desk board 10 when the folding desk is unfolded for use. In the structure according to the first embodiment, the inner leg 40 is retractable in a portion above the hinge point O, the table can be horizontally placed or switched to a front-low rear-high position, the table is horizontally placed in a state where the inner leg is fully extended, and the table is placed in a front-low rear-high position after the inner leg is shortened.

It will be appreciated that the provision of the catch 60 may not be necessary as the tensioning member 70 may restrain the inner leg 40 after it has been opened. However, if the bottom surface of the table 10 is provided with the latch 60 at the front end, the table is more stable at least when the table 10 is opened and horizontally placed for use, and the latch is latched with the inner leg link 50.

It will be appreciated that during shortening of the inner leg 40, the height of the inner leg link 50 is lowered and the position at which the inner leg link 50 supports the table 10 is moved inwardly.

In the present embodiment, the tension member 70 employs a webbing.

Example six:

referring to fig. 19 to 22, the sixth embodiment is different from the fifth embodiment in that: the tension member 70 is a hinge. Of course, the tensioning member could be replaced by a rope or chain.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
