The present invention relates to a kind of foldable structures of table leg, including table leg, guide rod, sliding block, connecting rod, table leg is rotatablely connected with desktop, table leg is connect by connecting rod with sliding block, sliding stroke of the sliding block with guide rod cooperation and on guide rod is limited, the guide rod is hinged by fixed seat and desktop, and connecting rod one end is hinged with table leg, and the other end is fixedly connected with a slide block.Invention has the advantages that：One, invention increases the arm of forces of support table leg still can provide the long arm of force especially when Desktop Dimensions are smaller, to improve the stability of whole desk；Two, without using guide rod almost isometric with desk, it is only necessary to which can work in the centrally disposed fixed point of desk can more save raw material, it is easy to accomplish the lightweight of product；Connecting rod and guide rod are connected by four-way sliding block, is integrated with limit, is connected, the multiple functions such as sliding, raw material are versatile, easy to produce, and installation is convenient for changing parts, it is easier to realize and promote.
Description
Technical field
The present invention relates to tables and chairs field, especially a kind of foldable structure of table leg.
Background technology
The patent No.：201220493945.8 disclose a kind of fold mechanism for folded table leg, this kind of mechanism includes：It leads
Bar is arranged on the bottom surface of desktop, and the middle part of the guide rod is equipped with elastic bumps；Sliding sleeve is reciprocally slidably arranged in described
On guide rod, the sliding sleeve is equipped with the limit hole for accommodating the elastic bumps；Litter, described litter one end are cut with scissors with table leg
It connects, the litter other end is hinged with the sliding sleeve, and table leg is hinged on desktop.The above mechanism solves desk occupied space
Greatly, the technical problem of storage trouble is carried.But it is shorter as the litter of support desk leg strength arm due to being used for after expansion, cause
The stability of said mechanism after deployment is bad.
Invention content
The shortcomings that the invention solves the above-mentioned prior arts provides a kind of folding of good, saving raw material the table leg of stability
Stack structure.
The present invention solves the technical solution of its technical problem use：The foldable structure of this table leg, including table leg, guide rod,
Sliding block, connecting rod, table leg are rotatablely connected with desktop, and table leg is connect by connecting rod with sliding block, and sliding block coordinates with guide rod and on guide rod
Sliding stroke it is limited, the guide rod is hinged by fixed seat and desktop, and connecting rod one end is hinged with table leg, and the other end is solid with sliding block
Fixed connection.
Preferably, two adjacent table legs are connect by shaft with desktop, or it is hinged with desktop respectively.
Preferably, two adjacent table legs are connect by an isometric connecting rod with sliding block respectively.
Preferably, the sliding block be four parts, for guide rod run through and the fixation of both sides connecting rod.
Preferably, the separate fixing end of the guide rod is set there are one hoodle, sliding block sets that there are one tunnels towards hoodle one end
Road, tunnel outside height are higher than in the height for bouncing state hoodle, and tunnel inside height is then less than in the height for bouncing state hoodle
Degree, the tunnel end are set there are one the trepanning that can coordinate with hoodle, and trepanning top is equipped with the button for pressing hoodle.
Invention has the advantages that：One, especially smaller in Desktop Dimensions invention increases the arm of force of support table leg
When, the long arm of force still can be provided, to improve the stability of whole desk；Two, without using almost isometric with desk
Guide rod, it is only necessary to can work in the centrally disposed fixed point of desk can more save raw material, it is easy to accomplish product it is light
Quantization；Connecting rod and guide rod are connected by four-way sliding block, is integrated with limit, is connected, the multiple functions such as sliding, raw material versatility
By force, easy to produce, installation is convenient for changing parts, it is easier to realize and promote.
Description of the drawings
Fig. 1 is the structural schematic diagram when present invention folds；
Fig. 2 is the structural schematic diagram after present invention expansion；
Fig. 3 is the sectional view of the present invention；
Reference sign：Table leg 1, shaft 2, guide rod 3, sliding block 4, fixed seat 5, connecting rod 6, hoodle 7, button 8, tunnel 9,
Trepanning 10.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings：
Embodiment：As shown, a kind of foldable structure of table leg, including table leg 1, guide rod 3, sliding block 4, connecting rod 6, table leg 1
It is rotatablely connected with desktop, table leg 1 is connect by connecting rod 6 with sliding block 4, and sliding block 4 coordinates with guide rod 3 and the sliding row on guide rod 3
Journey is limited, and the guide rod 3 is hinged by fixed seat 5 and desktop, and 6 one end of connecting rod is hinged with table leg 1, and the other end is fixed with sliding block 4
Connection.
Two adjacent table legs 1 are connect with desktop by shaft 2 and are connected respectively by an isometric connecting rod 6 and sliding block 4
It connects.The sliding block 4 be four parts, for guide rod 3 run through and the fixation of both sides connecting rod 6.
As shown in figure 3, the separate fixing end of the guide rod 3 is set there are one hoodle 7, sliding block 4 is equipped with one towards 7 one end of hoodle
A tunnel 9,9 outside height of tunnel are higher than in the height for bouncing state hoodle 7, and it is in bounce state that 9 inside height of tunnel, which is then less than,
The height of hoodle 7,9 end of tunnel are set there are one the trepanning 10 that can coordinate with hoodle 7, and 10 top of trepanning is equipped with for pressing bullet
The button 8 of pearl 7.
The side to overturn to outside desk in folding position of table leg 1, sliding block 4 is by 6 leash of connecting rod that two are in " eight words " type structure
The guide rod 3 of dynamic " word " type structure is lifted, two table legs 1 synchronize be turned to be vertically to desktop when, hoodle 7 passes through on sliding block 4
Tunnel 9, vertical direction receives extruding, until restoring pop-up state at trepanning 10, sliding block 4 is by 7 knot of hoodle on guide rod 3
Structure limitation continues to move, and entire fold mechanism locking cannot be moved mutually, to which folding table leg forms stable state.Such as Fig. 2 institutes
Show, guide rod 3 when table leg 1 opens up into operating position with connecting rod 6 almost on the same face, while constituting a longer power
Arm can give table leg 1 to provide a more firm support after locking, especially carry weight in desk centre.The arm of force is got over
Long, the stability of desk is higher, when Desktop Dimensions are smaller, still can provide the long arm of force, whole to improve
The stability of body desk.
When needing to fold, the button 8 of 10 top of trepanning is pressed, hoodle 7 sinks so that sliding block 4 breaks away from its limitation, simultaneously
Table leg 1 is pushed to be rotated to desk inner side, guide rod 3, which declines, drives table leg 1 to rotate, and " folding position is returned to from " operating position "
Set ", as shown in Figure 1.
In addition to the implementation, the present invention can also have other embodiment.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
