Activity is mostly to drive to field to carry out, and because vehicle space size limits, barbecue table is using collapsible.But existing folding table
Volume is general all bigger, and support is not sufficiently stable, and is easily arched upward or is collapsed.
The content of the invention
It is an object of the invention to provide a kind of attachment structure for folding table, the stability of strutting system of folding table is improved.
The present invention above-mentioned purpose technical scheme is that:A kind of connection knot for folding table
Structure, including the first hinged seat being installed on a table and the second hinged seat being installed on another table, described first is be hinged
Seat is hinged with second hinged seat by jointed shaft, and after two tables open flattening, the end face of first hinged seat is supported
Being provided with control on the end face for leaning against second hinged seat, between first hinged seat and second hinged seat, both are movable
Or locked control assembly.
Preferably, the control assembly includes being fixed in the limited block of first hinged seat and is rotatably installed in described
The joystick of second hinged seat, the joystick are provided with the jam plate contacted with the limited block, when the rotation control
When handle to the jam plate contacts with the limited block, first hinged seat is rotating down direction with second hinged seat
It is locked.
Preferably, the limited block is arranged on the lower section of the jointed shaft and the side of close second hinged seat,
The end face of the limited block forms 60 ° -75 ° of angle with horizontal plane.
Preferably, first hinged seat is provided with the first hinged disk, second hinged seat is provided with the second hinged disk, institute
State the first hinged disk and second hinged disk and be equipped with axis hole for installing the jointed shaft, the limited block is fixed in institute
State on the first hinged disk.
Preferably, the end face at first hinged seat both ends relative with second hinged seat is vertical end face, institute
The axle center for stating jointed shaft is located at the lower section of vertical end face and overlapped with the vertical end face.
Preferably, being connected between first hinged seat and the joystick stays open the joystick
Or the connection component of latched position, the connection component change itself and the jointed shaft with the switching of the joystick state
Relative position.
Preferably, the connection component includes extension spring, one end of the extension spring is fixed on first hinged seat, separately
One end is fixed in the lower end of the joystick, when the joystick is located at latched position, the line at the extension spring both ends
Positioned at the lower section of the joystick center of rotation, when the joystick is located at open position, the company at the extension spring both ends
Line is located at the top of the joystick center of rotation.
Beneficial effects of the present invention:The present invention is simple in construction, facilitates the expansion and folding of desk, and stability of strutting system is good, leads to
Crossing control assembly can effectively control table frame to rotate or fix, and switching state, realizes rapid deployment or folding, and deploying at any time
Carrying out locking makes desk keep stable state.

Embodiment
With reference to accompanying drawing, the present invention is described in further detail.This specific embodiment is only explanation of the invention,
It is not limitation of the present invention, and those skilled in the art, can be as needed to this implementation after this specification is read
Example makes the modification of no creative contribution, but as long as all being protected in scope of the presently claimed invention by Patent Law.
Embodiment:As depicted in figs. 1 and 2, a kind of attachment structure for folding table, including be installed on a table
One hinged seat 1 and the second hinged seat 2 being installed on another table, first hinged seat 1 pass through with second hinged seat 2
Jointed shaft 6 is be hinged.The end face at the first hinged seat 1 both ends relative with second hinged seat 2 is vertical end face, the jointed shaft
6 axle center is located at the lower section of vertical end face and overlapped with the vertical end face.After two tables open flattening, first hinge
The end face of joint chair 1 is resisted against on the end face of second hinged seat 2, between first hinged seat 1 and second hinged seat 2
Provided with both movable or locked control assemblies of control.Control assembly includes being fixed in the He of limited block 4 of first hinged seat 1
The joystick 3 of second hinged seat 2 is rotatably installed in, the joystick 3 is provided with the lock contacted with the limited block 4
Plate 31, when rotating the joystick 3 and being contacted to the jam plate 31 with the limited block 4, first hinged seat 1 with it is described
Second hinged seat 2 is to rotate down direction locked.
First hinged seat 1 is provided with the first hinged disk 11, and second hinged seat 2 is provided with the second hinged disk 21, and described first
Hinged disk 11 is equipped with the axis hole 12 for installing the jointed shaft 6 with second hinged disk 21, and the limited block 4 is fixed in
On first hinged disk 11.The limited block 4 is arranged on the lower section of the jointed shaft 6 and close to second hinged seat 2
Side, the end face of the limited block 4 form 60 ° -75 ° of angle with horizontal plane.
Being connected between first hinged seat 1 and the joystick 3 makes the joystick 3 stay open or latched position
Connection component, the connection component with the state of joystick 3 switching change its relative position with the jointed shaft 6
Put.Connection component includes extension spring 5, and one end of the extension spring 5 is fixed on first hinged seat 1, and the other end is fixed in described
The lower end of joystick 3, when the joystick 3 is located at latched position, the line at the both ends of extension spring 5 is located at the control
The lower section of the center of rotation of handle 3, when the joystick 3 is located at open position, the line at the both ends of extension spring 5 is positioned at described
The top of the center of rotation of joystick 3.
