The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

Like Fig. 1, Fig. 2 and Fig. 3, a kind of folding device of folding table is disclosed, it comprises base 1; The base 1 one ends seat of honour 3 that is articulated and connected, the seat of honour 3 can be rotated around swivel pin 8 with base 1, and can fit with base 1 fully in the seat of honour 3; The seat of honour 3 is built-in with block tongue 2; Block tongue 2 ends are provided with claw one 2a that stretches out from base 1 bottom, and base 1 other end is provided with the claw 24 that can fasten with claw one 2a, and block tongue 2 is built in the seat of honour; The one of which end offsets through an elastomeric element 5 and the seat of honour 3 inwalls, and the push rod 6 at the seat of honour 3 is stretched out in other end connection.

Like Fig. 3, the described folding device of the utility model, base 1 one ends are provided with claw 24; The seat of honour 3 is built-in with block tongue 2, and block tongue 2 ends are provided with claw one 2a and the claw 24 that stretch out from base 1 bottom and fasten, and form retaining mechanism interlock locking; Base 1 is provided with the installing hole that runs through up and down with the seat of honour 3, and base 1 is fixedly connected through bolt 11 with table pin 10, and the seat of honour 3 is fixedly connected through bolt 12 with desktop 9; Desktop closely is connected with a table pin, and rotated along swivel pin 8 at the seat of honour 3 when desktop put down, and claw one 2a runs into the claw 24 o'clock that is arranged at base 1 one ends; Block tongue 2 moves backward, when moving to the seat of honour 3 with base 1 applying, under the impetus of elastomeric element 5; Block tongue 2 moves forward, and makes claw one 2a and claw 24 on the block tongue 2 fasten locking, and desktop is connected with the locking of table pin.Desktop can not separate with the table pin when bearing downward pressure, and when upwards lifting desktop, a table pin can play motion with one of which, guarantees that desktop is connected with the reliable of pin, prevents that desktop from tumbling, and is safe and reliable; Block tongue 2 one ends that are built in the seat of honour 3 offset through elastomeric element 5 and the seat of honour 3 inwalls; The other end is connected with the push rod 6 that stretches out the seat of honour, promotes push rod 6 and makes block tongue 2 withdrawals, and claw one 2a can separate with the claw 24 of base 1 end; Desktop separates being connected of pin with table; Desktop is holded up, played folding effect, easy to operate.

The described folding device of the utility model mainly constitutes by the seat of honour that is built-in with block tongue 23 with the base 1 of its applying, forms retaining mechanism; After the seat of honour and base were fitted, claw one and claw two were hidden between the seat of honour and the base, and structure is firm; Do not receive ectocine; Desktop is connected with table pin locking, simple in structure, use accessory few, be fit to batch process; Desktop is fixedly connected with the seat of honour, and base just is connected with table pin top can accomplish installation, installs very convenient.

The described folding device of the utility model, after using repeatedly, claw one 2a and claw fasten for more than 24 time, and buckling surface 3a can produce untight problem of fitting because of wearing and tearing; Influence the reliability of retaining mechanism, make folding device produce potential safety hazard, for avoiding this problem, like Fig. 4; Disclose another kind of folding device, the buckling surface 3a of claw one 2a and claw 24 has been processed non-level inclined-plane, like this after the buckling surface 3a of pawl one 2a and claw 24 wearing and tearing; Under the impetus of elastomeric element, it so can fit tightly, and reaches identical purpose; Guarantee pawl one 2a and claw 24 lockings, safe and reliable, the service life of prolongation folding device.

Above-described folding device, described elastomeric element 5 is a spring, installs simply, and reaction is fast, can promote block tongue 2 rapidly and reset, and claw one 2a and claw 24 fasten locking.
