Description

Folding table
Technical field
The present invention relates to a kind of folding table, more particularly to a kind of table leg of folding table.
Background technology
Folding table is a kind of desk with folder function.When need not use folding table, it can be carried out Fold, the purpose in space is made full use of to reach.The table leg of folding table on the market is all placed in below desk after typically folding, When multiple folding tables are stacked together, it may appear that the table leg of different folding tables is mutually tangled, extremely inconvenience when deployed; The table leg of folding table is exposed outside on the market, also easily hides certain safety problem, especially the youngster smaller to the age Virgin or the elderly, easily falls down them as stop;The table leg of market folding table is usually by spring and shaft portion Composition, use time is slightly long, spring can fail, and table leg is not easy to be fixed, and the table leg of folding table is no longer firm, and folding table makes It is shortened with the life-span.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of folding table with table leg automatic locking-unlocking function, works as folding When folded table is not used, table leg is accommodated into the inside of table, and fixation between table leg and table is then by mechanical structure come real Now fix.
In order to solve the above technical problems, the present invention uses following technical scheme:A kind of folding table, including desktop, be arranged at Four folded table legs and baffler of desktop bottom, rotation intubation, the chair being adapted with folded table leg is provided with desktop bottom surface Leg holding tank, the bottom of the desktop is provided with and rotates intubation mounting groove and be provided with installation on the end face of chair leg holding tank fluting Hole, the both sides of leg holding tank are symmetrically provided with lock hole, and nearly bottom land end position is provided with salient point in chair leg holding tank, described Baffler neighboring be distributed with mounting hole adapt to coordinate mounting post, folded table leg include articulated column, table leg overcoat, Table leg inner sleeve with dovetail groove, the rotatable rotation elastic rod being installed in dovetail groove, installed in rotating elastic rod and dovetail groove Between elastic rod spring, be provided with the circular groove that ammunition feed bar spring is inserted in described dovetail groove, the articulated column and pullover in table leg Portion is hinged, and described table leg inner sleeve is placed in table leg overcoat;The inside of described articulated column is hollow structure, in articulated column and table The connection of leg overcoat is provided with the circular hole extended along articulated column length direction on end, and the inner face edge where circular hole is hinged column length side To fore-set sliding groove is provided with, the outer surface of articulated column is provided with through hole, and the through hole is connected with inner hollow, fore-set sliding groove institute The rotating hole perpendicular with through hole is provided with the whole;
Automatic locking mechanism is provided with described fore-set sliding groove, the automatic locking mechanism is provided with spring including bottom The slip fore-set of mounting hole, the fore-set spring being installed in spring mounting hole, two be respectively arranged in through hole and with rolling The clamping block of wheel, the retracting spring being respectively arranged between clamping block and articulated column inner surface, locked flapper, it is fixedly mounted on lock Determine the torsion spring of baffle plate and articulated column inner surface, the slip fore-set include the sliding shoe of bottom, the push rod on sliding shoe, The projection on top, the projection is installed in circular hole, and the sliding shoe is installed in fore-set sliding groove, is installed on spring mounting hole Interior fore-set spring also is located in sliding groove;The locked flapper upper and lower ends are column spinner and are installed in rotating hole, lock Determine the middle part of baffle plate to be cooperated for the symmetrical cam of profile and with the roller on clamping block, locked flapper is provided with and push rod The linked-baffle being engaged.
Improved as one kind:Described table leg inner sleeve be placed in table leg overcoat and the internal thread by table leg overcoat top with The tip male thread of table leg inner sleeve is connected, and described elastic rod spring is arranged on and rotates between elastic rod and dovetail groove and be fixed on In the circular groove that dovetail groove is provided with, the bottom of described table leg inner sleeve is provided with the spring column mounting groove for placing flexible spring column, and described stretches Contracting spring column spring is arranged on and stretches between spring column and spring column mounting groove, and flexible spring column ejection hole, institute are provided with set in table leg The table leg overcoat stated is provided with table leg fixing hole corresponding with ejection hole, and by stretching, spring column realizes table with the cooperation of table leg fixing hole Spacing fixation after leg stretching.
Improved as one kind:The upper and lower part of described table leg inner sleeve is distributed with external screw thread, the articulated column and table Leg inner sleeve head is hinged, and described table leg inner sleeve is placed in table leg overcoat, and by the internal thread and table leg at the top of table leg overcoat The external screw thread of inner sleeve is connected and realizes the adjustment of table leg length and fix
The beneficial effects of the invention are as follows:As a result of nested structure inside and outside table leg and automatic locking mechanism, table leg is by drawing Trail, rotate elastic rod and be ejected, and insert in the built-in rotation intubation of table bottom so that table leg is inwardly limited, together When table leg limitation locking in all directions is realized by automatic locking mechanism, folded table leg is fixed under table and locks It is fixed, it is to avoid table leg opens excessively outwards sliding phenomenon, combines double locking structure, the firm support of table leg.When folding table not During using being stowed away, folded table leg is by after folding, the sliding block in articulated column shrinks, and fixed to release, folding retractable table leg can quilt Push in the holding tank of table, folding table becomes one flat plate, eliminates potential safety hazard;When the folding table that multiple is packed up stacked When together, also it is less likely to occur to fall, the table leg of folding table will not mutual tied up in knots;Because articulated column is tied using machinery Structure is locked, low cost, be easily achieved, fault rate is low, the service life of table leg and folding table is greatly prolonged, and table leg can be received Enter chair leg standing groove, realize hiding, reduce volume, be easy to storage.
In order that the purpose, technical scheme and advantage of invention are clearer, the present invention is made into one below in conjunction with accompanying drawing The detailed description of step.
