New type description: [New technical field] Yuan can be used for wheelchairs, especially related to the backrest of the wheelchair [previous technique] and the width of the method combined with the wheel method to adjust the height == depending on the demand, in the traditional Wheelchairs can not be widely adapted: [New content] The main purpose of this skill is to provide a wheelchair, including - the body, two branches; the support unit of the support pole, and the second connection list connected to the back ^ * One for connecting the support bars and the backrest single = 3 bars are disposed on the side of the body f and are opposite to each other. Two from 2 having an outer officer, two inner tubes inserted at the two ends of the outer tube, a 4~-end extending cannula' and at least one back first-connecting unit connected to the outer tube, having - fixed to the outer a first body of the tube-end and a first fastening group connected to the first body. a socket body; a body 5 having a first protrusion: a first body that is sleeved to the outer tube; and between the first protrusions and connected to the first socket Located in the first triggering each first fastening group, having a first pulling member, a first pivoting portion at one end of the 3 M404007 member, and a first pivoting portion disposed in the opposite direction of the first pivoting portion And a first-long screw that is spliced with the first one and is connected to the first and second pivoting portions of the first screw, and a screw group The second fastening group on the long seat. Each second body of the first body is connected with two second bumps, _ for socketing the play-socket hole, and - for forming a second connection between the two bumps a set of perforation phase per-second fastening group' has a second second scale, a second pivoting portion located at the end of the second end The second long screw pivotally connected to the pivoting portion of the pivoting portion, and the second long screw pivotally connected to the pivoting portion of the pivoting portion, and a screw set in the second: the second nut. ^ Yu Le ~ the tube of the backrest unit The cannula, which is responsively coupled to the tube unit, is movably coupled to the second base body, and the unit can be used to smash the occupant's body shape and f to destroy ± and lower, the back ^ The width of the element can be flexibly deflected according to the width of the wheelchair to be assembled. [Embodiment] Firstly, please refer to the pictures of Figures 2 and 3, the wheelchair for this creation, including a 10, 2 building pole 2 〇, - back The unit 3 includes a seat portion n, a pedal group 12 disposed in front of the seat portion u, and a seat on the chair. seat ^The lower wheel set 13, and the lower M40007 are placed on the two sides of the seat portion 11 and the wheel set 14. The support rods 20 are disposed on the back side of the seat portion u and are in a standing state. The top end of the support rod 20 is respectively bent to form a handle 21. The backrest unit 30 is connected between the support rods 2〇, and the tube 3 is inserted into the inner tube 32 of the outer end of the outer tube 31, and two The inner tube has a cannula 33 extending at one end, and at least one backing member connected to the outer tube 31. Each of the first-connecting units 40 has a socket-fixed first body at one end of the outer & 41' and - the first fastening group connected to the first seat 41 commits a per-the-seat body, has two first bumps, and a first sleeve for socketing and fixing the outer tube 31-end The first hole 414 is formed in the first hole 412, and the first hole 414 is formed in the first socket 412. - the fastening group 42' has a - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - The first setting part of the reverse setting is gamma, - a first pad 423 abutting against the first arc recess 413, a first screw 422 ′ and a screw penetrating the first and second bumps 423 and the first pivoting portion 425 The first nut is similar to the first nut 422. Each of the second connecting units 5Q has a rib sleeve fixed to the fixing seat 5 of the branch 20 - a second seat connected to the fixing base 51 52: a second fastening group 53 connected to the second base 52. Each second base 52 has two second protrusions 521, a second sleeve 522, and one side of the second base 52 The second arc recess of the end commits 3, and - "between the second bumps 521 and the gap 524 with the second sleeve hole 52. The first first fastening group 53 of the first mother has a second triggering member mi, a 5 M404007, a second pivoting member 531, and a second pivoting portion of the second pivoting portion. The second pivoting portion 536 is disposed opposite to the second latching portion 536, and the first pivoting portion 521 of the second lining 4 is pivoted to the second pivoting portion 536. The screw 532 and a screw set are arranged in the second long screw to the sleeve 7 of the second sleeve hole 522. And one section: Τ Τ 4, 5, 6 and 7 'As assembled, the inner tube 32 is inserted into the body 4 at this time; a plate moving portion 426 is close to the first one of the first holes, and (4) ^ Close to each other and shrink the first set of ends, talk about the outer mountain and kiss the first set of holes 412 to force the outer tube 31 two 32 * 32 « seat (four) find the second ==_m 33__ and so on When the second bumps 521 are pulled one by one, the coffee is close to the second body 52, and the second sleeve holes 522 are tightened inside the second socket 522 to make the tube 33 The === waits for the lion body to hold the backrest unit 3〇33pi in the second seat back against the at least one of the body, the body 10 is firmly combined for the occupant to refer to 8 figure, when you want to adjust the support = the back of the seater. When the second triggering portion 537 is moved away from the height of 30, the inner diameter of the wrenching hole 522 is restored to the original shape by 5%, so that the second set: the cannula commits 'mobilizing the cannula; 3 Hold the set, and then move the second pulls to the position of the second set of holes 522 of the 6 Xuan special such as the broadcast tube 33 (such as the sixth figure = 53I # near the second body 52 to fix Positioning is good (4) to touch ^., can be _ backrest unit 30 to move and 6 i 凊 see Figure 9, when the backrest unit 3G width is to be adjusted, the first-pushing portion 426 leaves the first seat The body 41, such that the j pull = 2 inner diameter is restored to the original shape - the first socket - the hole is still no longer tightly clamped: two, 'bad so that the inner tube 32 can be telescopically mobilized at the two ends of the outer tube 31 Pulling the first-pushing portion 426 close to the first seat body 41 to be fixed), thereby (4) backing the unit to adjust the charm of the unit, the progressiveness of the creation lies in the backrest The unit 3 can be adjusted according to the size and needs of the occupant, and the width of the backrest unit can be mobilized according to the width of the chair, and the utility model has been implemented. And turn to the limit In this creation, anyone who is familiar with the art can still make some mosquito movements and (4) without departing from the spirit and scope of this creation. Therefore, the scope of this creation should be defined by the attached patent application shed and cover its legal scale, and is not limited to the previous description. [Simple diagram of the diagram] The first picture is the three-dimensional appearance of the creation; the second picture is a partial exploded view of the creation; the third picture is the exploded view of another part of the creation; the fourth picture is part of the creation The combined plan view shows the case where the inner tube is forced tightly; the fifth picture is a partial sectional view of the creation of the original tube, showing that the inner tube is inserted into the outer tube; the sixth picture is a combined plan view of another part of the creation, showing that the intubation is forced The tightness of the U404007 shape; Figure 7 is another sectional view of the other part of the creation, showing that the sliding member is placed in the second socket, the cannula is inserted into the sliding member; Figure 8 is a combination of this part of the creation The plan view shows that the backrest unit is adjusted to be at a higher position; and the ninth figure is a combined plan view of another part of the creation, showing that the inner tube of the backrest unit is adjusted to be wider.
