Description

Folding table

Technical field

It the utility model is related 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, to reach the purpose for making full use of space.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 mutually tangles, extremely inconvenient when deployed； The table leg of folding table is exposed outside on the market, also easily hides certain safety problem, youngster especially smaller to the age Virgin or the elderly, easily fall down them as stop；The table leg of market folding table is usually by spring and shaft portion Composition, usage time is slightly long, and 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 utility model provides a kind of folding table with table leg automatic locking-unlocking function, When folding table when not in use, table leg is accommodated into the inside of table, and the fixation between table leg and table then passes through mechanical structure To realize fixation.

In order to solve the above technical problems, the utility model uses following technical scheme：A kind of folding table, including desktop, set Four folded table legs and baffler, rotation intubation of desktop bottom are placed in, is provided with desktop bottom surface and is adapted with folded table leg Chair leg holding tank, the bottom of the desktop, which is provided with, to be rotated intubation mounting groove and is provided with the end face of chair leg holding tank fluting Mounting 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, The mounting post that cooperation is adapted to mounting hole is distributed with the neighboring of described baffler, and folded table leg includes articulated column, table leg Overcoat, the table leg inner sleeve with dovetail groove, the rotatable rotation elastic rod being installed in dovetail groove, installed in rotating elastic rod and ladder Elastic rod spring between shape groove, is provided with the circular groove that ammunition feed bar spring is inserted in described dovetail groove, the articulated column with table leg Set head 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 The circular hole for being provided with end and extending along articulated column length direction is connected with table leg overcoat, the be hinged column length in inner face edge where circular hole Degree direction is provided with fore-set sliding groove, and the outer surface of articulated column is provided with through hole, and the through hole connects with inner hollow, and fore-set slides Groove is provided with the rotating hole perpendicular with through hole on 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, it is described slide fore-set include the sliding shoe of bottom, the push rod on sliding shoe, The projection on top, the projection are 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, are locked The middle part of baffle plate is determined for the symmetrical cam of profile and is cooperated with the roller on clamping block, and locked flapper is provided with and push rod The linked-baffle being engaged.

As an improvement：Described table leg inner sleeve be placed in table leg overcoat and by the internal thread on table leg overcoat top with The tip male thread of table leg inner sleeve is connected, and described elastic rod spring, which is arranged on, to be rotated 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, spring column of stretching Spring, which is arranged on, to be stretched between spring column and spring column mounting groove, and is provided with flexible spring column ejection hole, described table on set in table leg Leg overcoat is provided with table leg fixing hole corresponding with ejection hole, realizes that table leg stretches by the cooperation of stretch spring column and table leg fixing hole Spacing fixation afterwards.

As an improvement：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 passes through the internal thread and table leg at the top of table leg overcoat The adjustment of table leg length and fixed are realized in the external screw thread mating connection of inner sleeve

The beneficial effects of the utility model are：As a result of nested structure inside and outside table leg and automatic locking mechanism, table leg warp Overstretching deploys, and rotates elastic rod and is ejected, and inserts in the built-in rotation intubation of table bottom so that table leg is inwardly limited Position, while the limitation locking of table leg in all directions is realized by automatic locking mechanism, folded table leg is fixed under table And lock, avoid table leg and open the phenomenon excessively outwards slided, combine double locking structure, the firm support of table leg.Work as folding When table is without using being stowed away, folded table leg is after folding, and the sliding block in articulated column shrinks, fixed to release, folding retractable table leg It can be pushed into the holding tank of table, folding table becomes one flat plate, eliminates potential safety hazard；When multiple folding table quilts packed up When being stacked 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 uses machine Tool structure latches, cost is low, be easily achieved, fault rate is low, the service life of table leg and folding table greatly prolongs, and table leg can Chair leg standing groove is incorporated into, realizes and hides, volume is reduced, is easy to store.

In order that the purpose, technical scheme and advantage of utility model are clearer, it is new to this practicality below in conjunction with accompanying drawing Type is described in further detail.
