[0021] like Figure 1-7 As shown, the utility model provides a foldable extended tray structure, including a tray 2 and a bracket 1, the top of the bracket 1 is provided with a connecting plate 3, the connecting plate 3 is provided with a fixing groove 9 and a sliding groove 10, the side of the tray 2 is slidably connected in the sliding groove 10, the side of the tray 2 is provided with a fixing pin 5, and the fixing pin 5 is matched and connected with the fixing groove 9.
[0022] As an embodiment of the utility model, a sliding nut 7 is provided on the side of the tray 2 , and a sliding member 6 passes through the sliding groove 10 and is connected to the sliding nut 7 , and the sliding member 6 slides in the sliding groove 10 .
[0023] As another embodiment of the present utility model, a gasket 8 is provided between the sliding member 6 and the sliding nut 7 .
[0024] As another embodiment of the present utility model, when the tray 2 is placed horizontally, the fixing pin 5 is clamped in the fixing groove 9 , and the sliding member 6 is located at the bottom end of the sliding groove 10 .
[0025] As another embodiment of the present utility model, when the tray 2 is folded and placed, the fixing pin 5 is disengaged from the fixing groove 9 , and the sliding member 6 is located at the bottom end of the sliding groove 10 .
[0026] As another embodiment of the present utility model, the fixing groove 9 is an open groove.
[0027] As another embodiment of the present utility model, an anti-collision pad 4 is provided on the bracket 1 .
[0028] The utility model provides a foldable extension tray structure, and the tray 2 can be used for various products, such as tables, chairs, workbenches, barbecue tables, etc. The bracket 1 and the tray 2 can be replaced by any material, not limited to iron, but also plastic.
[0029] The assembly process of the device is as follows. First, the tray 2 is aligned with the bracket 1, and the sliding member 6 is passed through the slide groove 10 on the connecting plate 3 and locked into the sliding nut 7. When locking, the gasket 8 is placed between the sliding member 6 and the sliding nut 7 to reduce wear during the sliding process. The fixing pin 5 is installed on the side of the tray 2, and the fixing groove 9 is designed as an open groove. The folding and opening operations of the tray 2 are realized by the engagement and disengagement of the fixing pin 5 and the fixing groove 9. At the same time, the anti-collision pad 4 is installed on the bracket 1 to prevent the tray 2 from colliding with the bracket 1 when folding and damaging the components. In this solution, the slide groove 10 is designed to be elliptical.
[0030] When folding, lift the tray 2 with both hands to disengage the fixing pin 5 of the tray 2 from the fixing groove 9. After losing the restraint of the fixing groove 9, the sliding member 6 first moves to the top in the sliding groove 10. After putting down the tray 2, the tray 2 and the bracket 1 are in a horizontal state. At this time, the sliding member 6 moves to the bottom in the sliding groove 10. The cooperation between the sliding member 6 and the sliding groove 10 can form a locking structure to prevent the tray 2 from falling off.
[0031] When opening, pick up the tray 2 with both hands, so that the fixing pin 5 on the tray 2 is inserted into the fixing groove 9, and then rotate with the fixing groove 9 as the fulcrum to make the tray 2 turn into a horizontal state. The tray 2 and the bracket 1 are in a vertical state, and the tray 2 is supported by the fixing groove 9. During this process, the sliding member 6 first moves to the top of the slide groove 10, and finally gets stuck at the bottom of the slide groove 10, forming a locking structure again, so that the tray 2 remains horizontal.
[0032] The tray 2 is rotated by using the fixing pin 5 and the fixing groove 9. This rotation design does not directly connect the rotating structure to the object, will not cause damage to the object body, and will not cause the tray 2 to loosen due to long-term rotation. Moreover, if the fixing pin 5 does not rotate smoothly at a later stage, only the fixing pin 5 needs to be replaced, which makes later maintenance more convenient.
[0033] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
