Accompanying drawing 2 is the mounting structure scheme drawing of armrest support of the present utility model.
Wherein: 1, rack body; 11, pilot hole; 12, pin-and-hole; 13, base plate; 14, side plate; 2, handrail tube; 3, treadle; 4, rotating shaft; 5, extension spring; 6, pin.
The specific embodiment
Come the technical solution of the utility model is further elaborated below in conjunction with accompanying drawing and specific embodiment.
Shown in Fig. 1～2, armrest support is provided with handrail tube 2, is used for the treadle 3 of the mode of operation of adjustment handrail tube 2.This armrest support comprises rack body 1, this rack body 1 is opening U font up, rack body 1 can be by base plate 13, the side plate 14 that is fixedly installed on base plate 13 left and right sides respectively forms, handrail tube 2 can be arranged on the rack body 1 by rotating shaft 4 along fore-and-aft direction turningly, be to arrange so in the present embodiment: radially offer a through hole (not shown) on the handrail tube 2, the diameter of this through hole should be a bit larger tham the diameter of rotating shaft 4, make and to relatively rotate between the rotating shaft 4 and handrail tube 2 when rotating shaft 4 is located in this through hole, the two ends that rotating shaft 4 passes above-mentioned through hole are arranged on respectively on the armrest support 1 regularly, like this handrail tube 2 just around the shaft 4 front and back overturn.The fore-and-aft direction here refers to the fore-and-aft direction of viewer's sight line when observing Fig. 1, Fig. 2, and accordingly, left and right directions refers to the left and right directions of viewer when observing Fig. 1, Fig. 2, the length bearing of trend of treadle 3 among this left and right directions that is Fig. 2.One end of handrail tube 2 is housed in the opening of rack body 1, the pin-and-hole 12 that runs through mutually about offering on the rack body 1, be provided with pin 6 in the pin-and-hole 12, pin 6 is located in to corresponding matching in the pin-and-hole 12 vertically, pin 6, treadle 3 lay respectively at the both sides of handrail tube 2 at rack body 1, pin 6, treadle 3, and the axial line of pin 4 is housed on the handrail tube 2 on end portion supports at least one parts in pin 6,3 two parts of treadle in rack body 1 opening all along horizontal left and right directions distribution.Like this, when 6 pairs of handrail tubes 2 of pin supported, pin 6 had better anti-pulling force characteristic, can provide handrail tube 2 stable supporting role power, and the setting of pin 6 was comparatively simple, installed more conveniently, had also reduced the productive costs of armrest support simultaneously.
Shown in Fig. 1～2, in the present embodiment, treadle 3 arranges in the following manner: offer the pilot hole 11 that runs through mutually along left and right directions on the rack body 1, the bearing of trend of pilot hole 11 rack body 1 be by forward direction after updip setting gradually, treadle 3 is located in the pilot hole 11 vertically, treadle 3 is mounted slidably along its bearing of trend in pilot hole 11, is provided with extension spring 5 between treadle 3 and the rack body 1, and the two axial ends of extension spring 5 is separately fixed in treadle 3, the rotating shaft 4.Treadle 3 height vertically when handrail tube 2 should make its vertically height of bottom be higher than treadle 3 when arranging to place pilot hole 11 nadirs.Like this, handrail tube 2 is when normal the use, as shown in Figure 2, the end that handrail tube 2 is housed in support 1 upper shed remains on the stable state that erects by the support of treadle 3 and pin 6, when needs are packed up handrail tube 2 when folding, the user steps on treadle 3, handrail tube 2 is 4 upsets forward around the shaft, treadle 3 is crossed in its bottom, unclamp treadle 3, treadle 3 returns back to original state and keeps out in the bottom of handrail tube 2 under the application force of extension spring 5, thereby prevents that handrail tube 2 from turning round, and makes handrail tube 2 remain under the state of packing up.
Referring to Fig. 1, shown in Figure 2, in the present embodiment, pin-and-hole 12 is square through hole, and accordingly, pin 6 is square square pin for radial section, and the radial section of square pin is consistent with the cross section of square through hole.Setting can make when pin 6 contacts with handrail tube 2 and to increase between the two contact surface like this.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection domain of the present utility model.
