The specific embodiment

The utility model embodiment provides a kind of frame, through folding dwindling the volume of a frame, thereby reduce taking up room of a frame.Another purpose of the utility model provides a kind of desk that comprises above-mentioned table frame.

For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

A kind of frame, rotatable linking together between the crossbeam of two adjacent table framves please refer to Fig. 1 and Fig. 2, the table frame plan structure sketch map that Fig. 1 provides for the utility model embodiment; The table frame side-looking structural representation that Fig. 2 provides for the utility model embodiment; Owing to be rotatable the connection between crossbeam and the crossbeam of table frame; So when not in use; Only need two adjacent relative rotations of crossbeam of table frame can be formed the long still less shape of volume of length, thereby dwindle the volume of a frame, reduce taking up room of a frame.

In order further to optimize such scheme; The crossbeam of table frame is collapsible beam 11; Please refer to Fig. 7, the structural representation after the table frame that Fig. 7 provides for the utility model embodiment is folding is in the time of can seeing the crossbeam rotation with the table frame; Simultaneously collapsible beam 11 is bent inwards, but the table frame length after folding so can still can not diminish by elongated volume.

Collapsible beam 11 can be arranged to the volume that any part doubling all can reduce a frame, and as preferred version, two parts folding each other in the collapsible beam adopt centering folding along its folding center symmetry, the maximum volume that has dwindled the table frame.

The collapsible beam 11 that the utility model provides comprises left part 112, right part 111 and with left part 112 and the right part 111 folding folding parts that link together.

Please refer to Fig. 3, the structural representation of the folding part that Fig. 3 provides for the utility model embodiment, the folding part comprises pin connector 32 and pin 31, the groove that left part 112 and right part 111 all offer the pin-and-hole that cooperates with pin 31 and hold pin connector 32.All insert pin in the pin-and-hole of left part 112 and right part 111, pin connector 32 is hinged with the pin in pin in the left part 112 and the right part 111, forms the folding part, and left part 112 can fold around the folding part with right part 111.

Because collapsible beam 11 often folds; In order to carry out consolidation process to collapsible, further prioritization scheme also is fixed with the

part

33,34 that reinforces the connection in the junction of left part 112 and/or right part 111 and folding part; The groove that the part 33 that reinforces the connection offers the pin-and-hole that cooperates with pin 31 and holds pin connector 32; All insert pin in the pin-and-hole of the part 34 that reinforces the connection of the reinforce the connection part 33 and the right part 111 of left part 112, pin connector 32 is hinged with the pin in pin in the left part 112 and the right part 111, forms the folding part; Left part 112 can fold around the folding part with right part 111; Like this through the

part

33,34 that reinforces the connection of better quality is set, the stressed of jackknife action at ordinary times transferred on the part 33 that reinforces the connection, prolonged the service life of table frame.

The form of another kind of folding part be can 180 ° of rotations rotary connector, rotary connector is fixedly connected with right part 111 with left part 112 respectively through screw, the installation and removal of the feasible frame of employing rotary connector are all very convenient.

The specific embodiment of the rotatable connection of crossbeam of the table frame that the utility model provides has the first termination connector 21 for one of them crossbeam; Another crossbeam has the second termination connector 23; The through hole that passes successively on the first termination connector 21 and the second termination connector 23 through bearing pin stepped screw 22 is fixed on the table leg of a frame, and this connected mode makes the easier for installation, quick of table frame.

Can certainly be directly that crossbeam is rotatable hinged through bearing pin.

In order further to optimize such scheme; Be fixed with bearing pin 211 on the first termination connector 21; Offer 90 ° annular through-hole 231 on the second termination connector 23, bearing pin 211 inserts in the annular through-hole 231, thereby limits the rotation limit of two adjacent crossbeams; The extreme position of 90 ° of annular through-holes 231 be exactly before adjacent two folding crossbeams with folding after extreme position, the user accomplishes folding more convenient to the table frame.

Mode the utility model embodiment of fixed pin shaft does not do qualification on the first termination connector 21.

In order further to optimize such scheme, be provided with first pad 24 at the first termination connector 21 with bearing pin stepped screw 22 contacts site, be used for whole rotational structure is sealed, can also play lubricated effect, reduce coefficient of friction.First pad is a teflon gasket, and this pad has good anti-aging, corrosion-resistant and heat resistance, better accomplishes sealing, and lubricated work and service life are longer.

In order further to optimize such scheme; Be provided with second pad 25 at the second termination connector 23 and the first termination connector, 21 contacts site; Prevent the mutual friction mutually of the first termination connector 21 and the second termination connector 23, second pad is a nylon spacer, and nylon spacer has higher tension compression strength; Be used for the first termination connector 21 and the second termination connector 23 often relatively rotates, and the bigger situation of pressure is most suitable.

Except above-mentioned table frame, the utility model also provides a kind of desk, comprises the described table of table and the above-mentioned each item that links to each other with table frame.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
