Abstract
The utility model discloses a tightening mechanism for dining chair fast mounting and dismantling which utilizes a support frame to clamp a table plate. The mechanism comprises a fixed seat which is fixed on the support frame. A tightening screw rod is capable of moving in axial direction to penetrate the fixed seat. The surface of the screw rod is provided with screw threads which utilize the upper ends to tighten the table plate. A positioning component is flexibly connected to the upper surface of the fixed seat and is provided with a gear engaging position and a dismantling position. By utilizing an elastic component, the positioning component is capable of remaining at the gear engaging position to be engaged with the screw threads on the tightening screw rod. In this manner, the tightening screw rod can move only in spiral manners.

The specific embodiment
The quick packing mechanism of child's table limit dining chair, its structure is following:
Like the packing mechanism of Fig. 2, table limit dining chair Fast Installation shown in Figure 3 and dismounting, in order to one be provided with the portion of taking 4 support frame 3 press from both sides apace and pull in the next door of table 90, it comprises at least: a holder 51, a packing screw 52 and an operating parts 53.
Described support frame 3 comprises that support frame 31 on, a pair of lower fulcrum bar 32 and take portion 4; Support frame 31 roughly takes the shape of the letter U on it, and socket or gluing sliding-proof pad 33 supply to be overlapped in the end face 92 of table 90 in both ends.
In the time will installing or unload limit dining chair; Last support frame 31 is near the weight of taking portion's 4 these ends; Touching table 90 parts with sliding-proof pad 33 or last support frame 31 is that fulcrum produces torque; Can make free end 35 keep being connected to the bottom surface 91 of table 90 and producing temporary transient positioning action, prevent support frame 3 disengaging tables 90.
Taking portion 4 can form by soft weaving cotton cloth (type of weaving cotton cloth or nylon dry goods) sewing, or with plastic jetting forming, inner blankets, cloth for baby is with cushion, and support frame 31 can suspended or be connected in the upper end in midair.
To shown in Figure 6, holder 51 is that connected modes such as available interlocking, riveted joint or welding are fixed between the stiff end 34 and free end 35 of lower fulcrum bar 32 like Fig. 4.
Packing screw 52 lies in appearance and is provided with screw thread, can run through holder 51 with moving axially, and upper end capable of using is packed in table 90 and the last support frame 31 common tables 90 that clamp.Can connect the bottom surface 91 that a clamp holder 55 supplies to push against table 90 in the upper end of packing screw 52.Further, clamp holder 55 can be embodied as an elastomer, in packing screw 52 upwards during packing table 90, uses producing strain and relax to prevent in use because of vibrations or to rock.
Each operating parts 53 is respectively equipped with an engaging piece 56 and a drive division 57; Can be installed in with stirring and have a position of engagement 50 and a disengaging configuration 60 above the holder 51, utilize a flexible member 54 to make it remain in the position of engagement 50 and with this packing screw 52 on screw-threaded engagement.
As shown in Figure 5, the strength of flexible member 54 makes the screw-threaded engagement of engaging piece 56 with the packing screw 52 of operating parts 53, and at this moment the rotatable packing screw 52 of user moves up and packing table 90 screw rod, uses and the last support frame 31 common tables 90 that clamp.
As shown in Figure 6; When operating parts 53 is pulled out when moving to disengaging configuration 60; Engaging piece 56 leaves the screw thread of packing screw 52, and at this moment the user can promptly move packing screw 52, makes upwards to push against table 90 fast to accomplish the installation of table limit dining chair; Or move packing screw 52 apace downwards, to accomplish the dismounting of table limit dining chair.
The flexible member 54 of present embodiment can be embodied as a compression spring, keeps engaging piece 56 to be positioned at the position of engagement 50 automatically.Drive division 57 can be a pull handle or handle; Drive division 57 in present embodiment is a button; The operator can make operating parts 53 50 move to disengaging configuration 60 from the position of engagement by pushing drive division 57, directly up pushes away packing screw 52, makes clamp holder 55 be able to press close at once the bottom surface 91 of table 90; Then can decontrol drive division 57; Flexible member 54 meshes the engaging piece 56 and the screw thread of packing screw 52 again; At this moment the turn packing screw 52; The strain that clamp holder 55 packing bottom surfaces 91 are produced to a certain degree makes support frame 3 stably clamp table 90, accomplishes the Fast Installation of the table limit dining chair of present embodiment.
And when the dining chair of operator's desire dismounting table limit; Can press drive division 57 once more or stir operating parts 53 with other modes; Make engaging piece 56 break away from the screw thread of packing screw 52, at this moment the operator can directly move packing screw 52 downwards, removes its packing to table 90 fast.
