Press the end 2123. When adjusting the front and rear positions of the armrest crossbar 20, the relief groove 25 on the side of the second guiding groove body 22 can leave a displacement space for the locking portion 2121 when sliding.

Since the relative position of the first guiding trough 12 and the sliding box 27 will change, the electric control part on the armrest crossbar 20 (that is, the wheelchair rocker 311, the first control button 312, the volume adjustment knob 323, the second control button 324) The circuit docking with the electric control part on the armrest bracket 10 is realized by the first adsorption member 13 and the second adsorption member 23. The possible docking method is as follows: when the first adsorption member 13 and the second adsorption member 13 When the member 23 is adsorbed, the first conductive portion 14 is connected to the second conductive portion 34. At this time, between the first adsorption member 13 and the second adsorption member 23, and between the first conductive portion 14 and the second conductive portion 34 , There is no relative displacement. Under the suction action of the first suction member 13 and the second suction member 23, the first guiding groove body 12 and the second guiding groove body 22 slide together relative to the sliding box 27, and then the armrest The position of the crossbar 20 is adjusted. The structure reduces the trouble caused by the manual plug butting, and the assembly is simple and the manufacturability is good.

The following describes the process of use in conjunction with the installation and cooperation relationship among the first guiding groove body 12, the second guiding groove body 22, and the sliding box 27:

1. If the user needs to remove the armrest crossbar 20, press the button 50 on the armrest crossbar 20 and act on the pressing end 2123 of the lock rod 212. The pressing end 2123 overcomes the elastic force of the resetting member 213 to compress the resetting member 213 , The lock rod 212 rotates around the rotation protrusion 211, the lock portion 2121 is withdrawn from the positioning hole 121; the armrest crossbar 20 is pushed backward, and the sliding protrusion 122 on the first guiding groove 12 and the sliding box 27 are now Align the card entry portion 275 of the card, and then press the pressing portion 62 at one end of the lock 60. The lock 60 overcomes the elastic force of the elastic member 64 and releases the locking portion 63. The cross bar 20 is lifted up, and the sliding protrusion 122 on the first guiding groove body 12 escapes from the card inlet portion 275 on the sliding box 27, and the armrest cross bar 20 can be removed.

2. After the user removes the armrest crossbar 20, under the action of the compression spring 241, the second fixing pin 243 of the stopper 24 moves upward in the bar-shaped second pin hole 222, and the position of the stopper 24 moves up and is The pressing member 28 is blocked. At this time, the second guiding groove 22 is confined in the first guiding groove 272 of the sliding box 27 to prevent the second guiding groove 22 from moving freely relative to the sliding box 27. At 20 o'clock, since the second guiding groove 22 is restricted by the first guiding groove 272, the first suction member 13 on the second guiding groove 22 directly adsorbs and butts with the second suction member 23, and causes the first The conductive portion 14 is electrically connected to the second conductive portion 34.

3. The first guiding groove body 12, the second guiding groove body 22, and the sliding box 27 on the left side and the first guiding groove body 12, the second guiding groove body 22 and the sliding box on the right side The specifications of 27 are the same. The user selects the installation position of the armrest crossbar 20 on the left or right side according to the setting of the first control part 31 and the second control part 32 on the armrest crossbar 20 according to their own hand habits, and after determining the installation position , Install it in the following way:

4 and 6, align the sliding box 27 in the armrest crossbar 20 with the support rod 11, and align the sliding protrusion 122 on the first guiding groove 12 with the card entrance 275, and align the armrest horizontally The rod 20 is pressed down. At this time, the second guiding groove body 22 is pressed and lifted by the first guiding groove body 12, and the sliding protrusion 122 is locked into the third sliding groove 274 and slidingly fitted with the third sliding groove 274. The guide ears 26 of the second guide groove 22 are matched with the upper edges of the first guide groove 272 and the second guide groove 273.

4 and 6, align the sliding box 27 in the armrest crossbar 20 with the first guide groove 12 provided on the support rod 11, and make the sliding protrusion 122 on the first guide groove 12 and The card entrance portion 275 is aligned, and the armrest crossbar 20 is pressed down. At this time, under the support of the support rod 11, the second guiding groove body 22 and the first guiding groove body 12 overcome the downward force of the compression spring 241 and Move up relative to the sliding box 27, so that the guide ear 26 of the second guide groove 22 can slide relative to the armrest crossbar 20 at the upper edge position of the first guide groove 272 and the second guide groove 273, which can be expressed as the first A guide trough body 12 and a second guide trough body 22 are fixed, the armrest crossbar 20 slides relative to the first guide trough body 12 and the second guide trough body 22, while the sliding protrusion 122 is locked into the third sliding groove 274 and It is in sliding fit with the third sliding groove 274.

4. If the user needs to adjust the position of the armrest crossbar 20 back and forth, press the button 50 on the armrest crossbar 20 and act on the pressing end 2123 of the lock lever 212. The pressing end 2123 overcomes the elastic force of the resetting part 213 to make the resetting part 213 After being compressed, the lock lever 212 rotates around the rotating protrusion 211, the locking portion 2121 withdraws from the positioning hole 121, and after being adjusted in place, the button 50 is released, the locking portion 2121 is locked into the positioning hole 121 again, and the armrest crossbar The position of 20 is locked, and the armrest crossbar 20 cannot move back and forth, nor can it escape from the support rod 11.

The user’s usage habits may be different (left-handed and right-handed as we say). The user can conveniently swap the left and right handrail bars 20 according to their own operating habits to facilitate the user to choose his own suitable way Control the wheelchair. 4. If the user wants to adjust the front and rear position of the armrest crossbar 20, he can press the button 50 on the armrest crossbar 20, the locking part 2121 of the lock rod 212 is withdrawn from the positioning hole 121, and the armrest crossbar is pushed forward and backward. 20.
