As shown in Figure 10, it is the deployed condition structural representation that the utility model adjusts support plate structure.

As shown in Figure 10, a kind of regulation support plate structure, its supporting construction for being used to constitute wheelchair is simultaneously realized to the fast of wheelchair Speed is folded, and the regulation support plate structure includes an X-type support plate 71, an auxiliary pole 72, a vertical support frame 73；The auxiliary pole 72 are used to realize the reinforcing connection to the X-type support plate 71 and the vertical support frame 73, and with reference to shown in Fig. 3, it is new this practicality Type adjusts the auxiliary pole schematic diagram of support plate structure, and the auxiliary pole 72 includes an elongated hole pole 723, the elongated hole pole 723 one end are provided with an elongated hole 721, and the elongated hole 721 is connected by one first bearing pin 741 with the X-type support plate 71, the length The other end of hole pole 723 is connected with the vertical support frame 73 by one the 3rd bearing pin 743, and the auxiliary pole 72 also includes a card Joint chair 724, the elongated hole pole 723 is provided with the one end of the elongated hole 721 through clamping seat 724；The auxiliary pole 72 Also include a spring 722, the spring 722 is placed in inside the elongated hole 721, and is together placed in institute with the elongated hole pole 723 State inside clamping seat 724；The one end of the spring 722 abuts against with the elongated hole 721, and the other end offsets with clamping seat 724 Connect；A through hole is additionally provided with the clamping seat 724, the through hole is common by first bearing pin 741 with the elongated hole 721 It is fixed on the X-type support plate 71.

With reference to shown in Figure 10, Figure 11, Figure 12, lower end and the lower end of the vertical support frame 73 of the X-type support plate 71 pass through one 4th hinge 744 is connected, and the first abutment extending 711 is provided with the X-type support plate 71, and abutment extending frame is provided with the vertical support frame 73 731, first abutment extending 711 is engaged realization with the abutment extending frame 731 to the upper end of X-type support plate 71 and the vertical support frame The fixation of 73 upper ends.The top of the vertical support frame 73 is provided with the second abutment extending 732, and the bottom of the vertical support frame 73 is provided with the 3rd Abutment extending 733, second abutment extending 732 realizes the constraint to the vertical support frame 73 with the 3rd abutment extending 733 jointly, makes homonymy The vertical support frame 73 be fixed.An arc groove 725 is additionally provided with the elongated hole pole 723, it is used for described When regulation support plate structure is in folded state, the elongated hole pole 723 does not interfere with second abutment extending 732, so that The regulation support plate structure is folded as far as possible, and space hold reaches minimum area.

Because the bottom of the vertical support frame 73 is fixed by the 3rd abutment extending 733, the X-type support plate 71 is by described the Four hinges 744 are fixed on the bottom of the vertical support frame 73, and first abutment extending 711 that the top of X-type support plate 71 is set will The top of X-type support plate 71 is fixed, so that the X-type support plate 71 forms the structure of stabilization.

When the regulation support plate structure is in deployed condition, first abutment extending that the top of X-type support plate 71 is set 711 are interlockingly connected with the abutment extending frame 731, so that the regulation support plate structure forms the three-legged structure of stabilization, prevent because shaking It is dynamic to cause the regulation support plate connection loosing.

As shown in Figure 10, one second bearing pin 742 is additionally provided with the X-type support plate 71, it is used for the X-type support plate 71 Chiasma type support plate be attached, realize the pivoting of the X-type support plate 71.

When the regulation support plate structure is pushed as deployed condition by folded state, 71 pairs of auxiliary of the X-type support plate Pole 72 applies the power along the long axis direction of the auxiliary pole 72 obliquely, now inside auxiliary pole 72, the clamping seat 724 Equally apply power obliquely against 722 pairs of elongated hole poles 723 of spring, the elongated hole pole 723 continues power to pass to The vertical support frame 73, so as to promote the vertical support frame 73 to be opened to both sides.

When the regulation support plate structure is fully deployed, it is necessary to first abutment extending 711 is fallen into the abutment extending frame just In 731 groove, so as to realize launching and fix, now the structure type of the elongated hole 721 has regulation and adaptation function, For eliminating design and making the error for producing, can when first abutment extending 711 falls the elongated hole 721 it is interior carry out it is small Scope is adjusted, so as to more easily fall into the abutment extending frame 731, it is to avoid drop down onto the abutment extending frame under first abutment extending 711 731 cause inaccurate due to the error for designing and manufacture.

The elongated hole 721 is engaged by with the spring 722, makes the moment of the spring 722 against the elongated hole 721, The elongated hole 721 is avoided to produce fit clearance with first bearing pin 741, so as to avoid generation loosely in actually used process The phenomenon for collapsing；Simultaneously because the presence of the spring 722, greatly improves smooth degree when X framves are opened, closed, without card Astringent sense.

The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art Art personnel, on the premise of the utility model method is not departed from, can also make some improvement and supplement, and these improve and supplement Also should be regarded as protection domain of the present utility model.
