Description

Technical Field

[0001] The utility model relates to the field of folding tables, in particular to a locking mechanism for a folding table. Background Art

[0002] A folding table is a table with a folding function. It is generally made of steel and wood and is characterized by being easy to fold and transport.

[0003] Compared with the existing technology, there are problems: the existing folding tables mostly use two-section rotatable support rods to support and position the table legs when in use. When the folding table is found to be offset, the support rods will rotate and lose the support effect on the table legs, causing the folding table to tip over. The stability of the folding table during use is poor. Secondly, the existing folding tables cannot quickly store the table legs, resulting in low efficiency in the unfolding and storage operations of the folding table. For this reason, we propose a folding table with a support and positioning function and a locking mechanism that allows for rapid storage and unfolding to solve the above problems.

When the card block 320 is locked and positioned, the spring 321 squeezes the card block 320, which can keep the card block 320 tightly against the outside of the ratchet 310, thereby improving the stability of the folding table during support and use, and can quickly complete the unfolding and folding of the folding table, thereby improving the convenience of using the folding table, and having high practicality and functionality.

[0033] Specifically, a buffer pad 110 is fixed to one side of the table top 100; by providing the buffer pad 110 to buffer and support the edge of the table top 100 when the folding table is in use, the tension of the contact parts of a pair of table tops 100 is ensured, thereby improving the integrity of the folding table in use.

[0034] Specifically, the side wall of the support sleeve 220 is fixed with a connecting cross bar 221 by bolts; by providing the connecting cross bar 221 to fix the two relative groups of support sleeves 220, the positions of a pair of support sleeves 220 can be kept relatively fixed, thereby ensuring the stability of the support sleeve 220 in supporting the folding table.

[0035] Specifically, a handle 341 is fixed to one end of the pull bolt 340 ; by providing the handle 341 with a finger outline, it is convenient for the user to pull the pull bolt 340 to move during the unlocking operation, thereby improving the efficiency of the unlocking operation.

[0036] Specifically, the adjustment component includes a support column 410, which is slidably connected to the inner wall of the support sleeve 220, and a mounting rod 420 is fixed to the side wall of the support column 410. A plurality of positioning holes 430 are opened on one side of the support column 410, and a locking bolt 440 is threadedly connected to the outer side of the support sleeve 220; by providing an adjustment component, the support height of the folding table can be adjusted according to usage requirements by screwing the locking bolt 440 and inserting it into the positioning hole 430, and the folding table can be supported by the support sleeve 220 and the support column 410.

[0037] Specifically, a support pad 411 is fixed to the bottom of the support column 410; the support pad 411 increases the friction between the support column 410 and the ground, thereby preventing the folding table from sliding when in use.

[0038] Specifically, the connecting component includes a mounting plate A510, which is fixed to one side of the table top 100 by bolts. The inner wall of the mounting plate A510 is rotatably connected to a connecting shaft pin 520, and the outer side of the connecting shaft pin 520 is rotatably connected to a mounting plate B530. By providing a connecting component, a pair of table tops 100 are connected together by the mounting plate A510 and the mounting plate B530, thereby realizing the folding and storage of the table top 100.

[0039] Working principle: When in use, a pair of table tops 100 are connected together through the mounting plate A510 and the mounting plate B530 to realize the folding and storage of the table tops 100. The edge of the table top 100 is buffered and supported by the buffer pad 110 to ensure the tension of the contact parts of the pair of table tops 100. When the folding table needs to be unfolded and used, the support sleeve 220 is pulled to the vertical state. During the process, the support sleeve 220 drives the mounting shaft 210 to rotate, and the mounting shaft 210 drives the mounting shaft 210 to rotate. When the support sleeve 220 is rotated to the vertical state, the support sleeve 220 has a tendency to rotate to the folded position under the action of the torsion spring 230. This rotation tendency is transmitted to the ratchet 310 through the mounting shaft 210, and the ratchet 310 has a tendency to rotate in the opposite direction. At this time, the block 320 and the ratchet 310 are meshed with each other, and the block 320 can be positioned at this position to prevent the ratchet 310 from rotating, thereby achieving the support The automatic locking and positioning of the support sleeve 220 can quickly unfold the folding table. When the block 320 is locked and positioned, the spring 321 squeezes the block 320 to keep the block 320 tightly against the outside of the ratchet 310, ensuring the stability of the ratchet 310 and the block 320 in the locked and positioned state, and preventing the ratchet 310 from being separated from the block 320. By twisting the locking bolt 440 and inserting it into the positioning hole 430, the folding table can be quickly unfolded and used. When the block 320 is locked and positioned, the spring 321 squeezes the block 320 to keep the block 320 tightly against the outside of the ratchet 310, and ensures the stability of the ratchet 310 and the block 320 in the locked and positioned state, and can prevent the ratchet 310 from being separated from the block 320. The support height of the folding table is adjusted, and the support sleeve 220 and the support column 410 cooperate to support the folding table. When the folding table needs to be stored, the block 320 is moved by pulling the pull bolt 340, so that the block 320 is disengaged from the ratchet 310. At this time, under the action of the torsion spring 230, the mounting shaft 210 and the support sleeve 220 rotate, and the support sleeve 220 quickly returns to the folded and stored state, which can quickly complete the unfolding and use as well as the storage and folding of the folding table.
