Description

Technical Field

[0001] The utility model relates to the field of furniture manufacturing, in particular to a sliding folding mechanism and a folding table. Background Art

[0002] In families, folding tables are widely used. Existing folding tables have a single-sided iron sheet with a groove in the middle folding mechanism, an S-shaped iron sheet and a U-shaped combined mechanism, a reinforced pipe with a groove folding mechanism, and an intermediate connecting pipe and a bent connecting iron sheet combined mechanism. After folding in place, these structures all require people to bend down to check or touch whether they are folded in place, without a prompt effect for folding in place. Moreover, the existing folding locking structures are relatively simple and easily lead to the loosening of the locking structure, affecting the use of the folding table. Summary of the Invention

[0023] As Figure 1-7 shown, the present utility model provides a sliding folding mechanism, including a guide rod 1, a slider 2 with a hollow structure, a locking structure, a first folding rod 3 and a second folding rod 4. The slider 2 is arranged on the guide rod 1, the slider 2 moves along the guide rod 1, the first folding rod 3 and the second folding rod 4 are respectively connected to both sides of the slider 2, the locking structure is arranged in the slider 2, and the guide rod 1 is provided with a locking hole 11 which is cooperatively connected with the locking structure.

[0024] As an embodiment of the present utility model, a limit block 5 is provided at the top end of the guide rod 1, the limit block 5 is provided with a first mounting hole 9, the top end of the guide rod 1 is provided with a second mounting hole 10, and the first mounting hole 9 and the second mounting hole 10 are connected through a limit connecting piece 8.

[0025] As another embodiment of the present utility model, a rod cavity 12 for placing the guide rod 1 is arranged inside the slider 2, a locking cavity 13 for arranging the locking structure is arranged on one side of the rod cavity 12, and a partition plate 14 is arranged between the rod cavity 12 and the locking cavity 13.

[0026] As another embodiment of the present utility model, the partition plate 14 is provided with a pin hole 15 communicating the rod cavity 12 and the locking cavity 13.

[0027] As another embodiment of the present utility model, the locking structure includes a locking button 6, a latch 16 and a rotating shaft 7. One end of the latch 16 is connected to the locking button 6, and the other end of the latch 16 is disposed in the latch hole 15. The sliding block 2 is provided with a first rotating hole 19, and the locking button 6 is provided with a second rotating hole 20. The rotating shaft 7 is connected in the first rotating hole 19 and the second rotating hole 20.

[0028] As another embodiment of the present utility model, one end of the latch 16 is provided with a third mounting hole 17, and an insertion member 18 is disposed inside the locking button 6. The insertion member 18 is connected in the third mounting hole 17.

[0029] As another embodiment of the present utility model, a torsion spring 21 is disposed in the locking cavity 13. The middle of the torsion spring 21 is sleeved on the rotating shaft 7. One end of the torsion spring 21 abuts against the inside of the locking button 6, and the other end of the torsion spring 21 abuts against the partition 14.

[0030] As another embodiment of the present utility model, when the locking hole 11 and the latch hole 15 are on the same horizontal line, the other end of the latch 16 is inserted into the locking hole 11.

[0031] The present utility model further provides a folding table, which includes a sliding folding mechanism, a table frame 22, a tabletop 25 and two leg frames 24. The two leg frames 24 are respectively connected to the two sides of the bottom of the table frame 22. The tabletop 25 is disposed on the top of the table frame 22. The bottom end of the guide rod 1 is connected to a cross bar 23 in the middle of the table frame 22. The first folding rod 3 and the second folding rod 4 are respectively connected to the two sides of the leg frame 24.

[0032] In the folding table of the present utility model, by sliding the sliding block 2 on the guide rod 1, the first folding rod 3 and the second folding rod 4 are driven to gather or expand, so as to realize the folding and unfolding of the leg frame 24 and achieve the folding function. At the same time, a sound will be emitted when the sliding block 2 reaches the locking position, prompting the user that the locking is in place and giving the user a better use experience.

[0033] When the sliding and folding mechanism is assembled, insert the guiding rod 1 into the rod cavity 12. A hole with the same shape as the guiding rod 1 is provided in the rod cavity 12. The limiting block 5 is provided at the top of the guiding rod 1. Connect the limiting connecting piece 8 to the first mounting hole 9 and the second mounting hole 10 to realize the connection between the limiting block 5 and the guiding rod 1. The bolt 16 is connected to the locking button 6 through the plugging piece 18. One end of the bolt 16 can rotate around the plugging piece 18. Place the other end of the bolt 16 in the bolt hole 15. Connect the rotating shaft 7 to the first rotating hole 19 and the second rotating hole 20. The first rotating hole 19 is provided above and below the sliding block 2. In this way, the locking button 6 can rotate around the rotating shaft 7. The locking button 6 and the bolt 16 form a lever structure. When pressing the locking button 6 in the direction of the guiding rod 1, the locking button 6 rotates, and the bolt 16 will move away from the bolt hole 15. A torsion spring 21 is provided between the locking button 6 and the partition 14. When pressing the locking button 6, the torsion spring 21 will be compressed under force. When released, the torsion spring 21 rebounds to drive the bolt 16 to reset.

[0034] When the folding table is in the folded state, the first folding rod 3 and the second folding rod 4 are in a gathered state. When using the folding table, hold the sliding block 2 and slide it along the guiding rod 1 towards the top. At this time, the other end of the bolt 16 will slide along the surface of the guiding rod 1. The first folding rod 3 and the second folding rod 4 also expand outwards accordingly. When the sliding block 2 slides to the limiting block 5 and is blocked, at this time the bolt 16 will insert into the locking hole 11, making a "click" sound, which proves that the sliding block 2 has moved to the locking position, the leg frame 24 has been fully opened, and the bolt 16 locks the movement of the sliding block 2. When the folding table is in use, the sliding block 2 will not become loose and fall off, ensuring the stability of the folding table.

[0035] When folding the folding table, hold the sliding block 2 and press the locking button 6 to make the locking button 6 rotate around the rotating shaft 7. When pressed to the limit distance, the bolt 16 will disengage from the locking hole 11 and move away from the bolt hole 15. Then slide the sliding block 2 along the guiding rod 1 towards the bottom end. Then the first folding rod 3 and the second folding rod 4 also start to gather as the sliding block 2 moves, and drive the leg frame 24 to fold towards the table frame 22. When the folding of the leg frame 24 is completed, release the locking button 6. The torsion spring 21 rebounds to make the bolt 16 return to the bolt hole 15. When the folding of both leg frames 24 is completed, the folding table is in the folded state.

[0036] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present utility model.
