The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A height-adjustable collapsible table leg, forms as Figure 1-4, comprises two supporting legs, and the end that the sidepiece of every supporting leg is provided with 14, the two universal joint connecting rods 14 of universal joint connecting rod that are formed by connecting by universal joint interconnects; Described supporting leg comprises the horizontal cross bar 1 for supporting desktop, the middle part of horizontal cross bar 1 is provided with contiguous block 3, contiguous block 3 is provided with the tooth bar 4 that is arranged in parallel and without gear rack 5, tooth bar 4 and have shell 6 without gear rack 5 outsides covers, the lower end of shell 6 is provided with rotatable bindiny mechanism 9, the bottom of rotatable bindiny mechanism 9 is provided with V-type leg 10, and the middle part of V-type leg 10 is provided with V-type leg connecting rod 11; Described shell 6 is provided with the knob assembly 8 that connects tooth bar 4 and universal joint connecting rod 14.
The end of described two universal joint connecting rods 14 interconnects through internal and external threads bindiny mechanism 13.
Between described contiguous block 3 and horizontal cross bar 1, be provided with folding fastener 2.
Between described rotatable bindiny mechanism 9 and shell 6, be also provided with Fast detachable unit 12.
Described knob assembly 8 comprises that described spline 20 coordinates with spline 17 with the knob 15 of spline 20 with the gear shaft 18 of spline 17, and described gear shaft 18 is provided with and tooth bar 4 meshed gears 19, and gear shaft 18 is also connected with universal joint connecting rod 14.
Described knob 15 is provided with boss 16, and boss 16 coordinates with the index hole 21 on shell 6, and described knob 15 outsides are provided with stop screw 7.
As shown in Figure 2, the utility model unclamps internal and external threads bindiny mechanism, and table leg is divided into two supporting legs in left and right, and frame for movement folds the object that reaches folding by rotatable bindiny mechanism.Described rotatable bindiny mechanism is arranged on the below of shell, the V-type leg of two band gears can be meshed and be drawn in by gear, when the Fast detachable unit of rotatable bindiny mechanism one side unclamps, rotatable bindiny mechanism is rotated around the axle of opposite side, completes folding.Frame for movement is carried out self-locking by folding fastener (comprising folding fastener-horizontal component and folding fastener-vertical portion) and knob assembly.Described folding fastener-horizontal component is arranged on the below of horizontal cross bar, and self-locking, by cylindrical elongated pore, can be carried out in folding fastener-horizontal component side; Knob assembly comprises with the knob of spline and boss, with the gear shaft of spline, with shell, the stop screw of index hole and gear shaft installing hole.Gear shaft is arranged on the gear shaft installing hole of shell, knob is arranged on the gear shaft with spline by spline, can move left and right, the right is spacing by stop screw, the left side is undertaken spacing by the length of gear shaft upper spline groove, when in left side extreme position, the boss of knob coordinates with the index hole of shell, but not can with shell in tooth bar interfere, reach the object of self-locking.
The utility model reaches the object of lifting simultaneously by universal joint connecting rod.Described universal joint connects and is connected cooperation with gear shaft, when knob rotarily drives gear shaft rotation, the power of gear shaft rotation is delivered to universal joint connecting rod, left and right universal joint connecting rod is rigidly connected by internal and external threads bindiny mechanism, by universal joint connecting rod, be delivered on the gear shaft of opposite side, then wheel and rack generation relative displacement, realizes left and right sides lifting simultaneously.
It is as follows that the utility model is used: the first step, by deployed condition to folded state.Unclamp internal and external threads bindiny mechanism, make the left and right sides separately, turn knob makes tooth bar to minimum state, lifts V-type leg connecting rod, and V-type leg is drawn close, unclamp and take down Fast detachable unit, rotatable bindiny mechanism and its underpart are pivoted, stir the bar in folding fastener-horizontal component and folding fastener-vertical portion, make from this limiting condition to another limiting condition, complete the folding of folding fastener, complete above process and realize from deployed condition to folded state.
Second step, to deployed condition, stirs the bar in folding fastener by folded state, makes from this state to another limiting condition, and rotation V-type leg, fixes V-type leg and rotatable connection with Fast detachable unit, pushes V-type leg aside to limiting condition.Then universal joint, universal joint connecting rod, internal and external threads bindiny mechanism are coupled together, turn knob, the power of rotation rises the right and left by universal joint, universal joint connecting rod simultaneously.Completing above process realizes from folded state to deployed condition.
