Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
As shown in Figures 1 to 6, it is a kind of can any adjusting angle of backrest sofa, including several couch units, the sand
Sending out chair unit includes sofa frame portions and angle adjusting mechanism, and the sofa frame portions include pedestal 1, seat frame 2 and backrest
3, the pedestal 1 includes two base side plates 11, and the base side plate 11 is respectively equipped with front end mounting portion 12 and rear mounting portion 13,
The seat frame 2 includes two seat frame side plates 21, and the backrest 3 includes two backrest side plates 31, and sofa frame portions are equipped with adjusting back
Frame 3 connect the angle adjusting mechanism of angle with seat frame 2.
The angle adjusting mechanism includes support plate 51 and arc-shaped guide rail 53, on the outside of described 51 one end of support plate with it is described after
It is fixedly connected on the inside of the mounting portion 13 of end, slide protrusion 52 is equipped on the outside of 51 other end of support plate.The arc-shaped guide rail 53 1
End outside on the inside of the seat frame side plate 21 connection, the other end inside and connected on the outside of the backrest side plate 31, the arc is led
Rail 53 is slidably connected with the slide protrusion 52 cooperation.The angle adjusting mechanism further includes being set on the seat frame side plate 21
Preceding guide groove 22 and rear guide groove 23, the front end mounting portion 12 are equipped with the front wheel being cooperatively connected with the preceding guide groove 22,
The rear mounting portion 13 is equipped with the rear roller being cooperatively connected with the rear guide groove 23.In the application, if two base side plates 11
Opposite side is the inside of plate, if two base side plates, 11 phase back side is the outside of plate.

Support plate 51 and pedestal 1 are fixed again after connecing two support plates 51, on the one hand may make two support plates, 51 symmetry good, on the other hand
The support strength of support plate 51 can be improved.Pass through guide rail branch on the inside of two arc-shaped guide rails 53 and 21 connecting pin of seat frame side plate
Strut connection.Guide supporting bar can be first passed through and connect again that arc-shaped guide rail 53 and seat frame 2 is fixed, one side after two arc-shaped guide rails 53
Two arc-shaped guide rails, 53 symmetry can be made good, the intensity of arc-shaped guide rail 53 on the other hand can be improved.
The front wheel includes rotary shaft body 61, and 61 periphery of rotary shaft body is arranged with roller body 62, the rotary shaft body 61 1
End is equipped with magnetic adsorption plate 63, the other end is connect with the front end mounting portion, and axial cavity, the axis are equipped with inside the rotary shaft body 61
The iron core 64 connecting with the magnetic adsorption plate 63 is equipped with into cavity, the iron core 64 is wound with coil 65, and the coil 65 passes through
The switch being arranged on sofa connects to power supply, and the preceding guide groove 22 includes the outer vallecular cavity 221 for accommodating the roller body 62, holds
The magnetic setting the interior vallecular cavity 222 of the magnetic adsorption plate 63 and being used cooperatively set on preceding 22 bottom of guide groove and the magnetic adsorption plate 63
Butt joint body 223.
After the backrest angle of sofa regulates, can directly press the switch on sofa so that coil 65 be powered and with
Iron core 64 cooperate so that magnetic adsorption plate 63 generate magnetic attraction, at this point, magnetic adsorption plate 63 can be connect with 223 magnetic of magnetic butt joint body with will before
Idler wheel and preceding guide groove 22 are fixed, thus seat frame 2 and pedestal 1 is fixed, so that slide protrusion 52 is in the position of arc-shaped guide rail 53
Fixed, then backrest 3 and the connection angle of seat frame 2 are also fixed, then sofa can normal use.When need replacing sofa by dorsal horn
When, it can turn off the switch, so that magnetic adsorption plate 63 loses magnetic attraction, front wheel and preceding guide groove 22 normally opposite can be slided, and work as sofa
Backrest angle presses the fixed switch of backrest again after regulating.The structure of rear roller and rear guide groove 23 and front wheel and it is leading to
The structure of slot 22 is identical.
As shown in fig. 7, the couch unit further includes the air bag 7 being arranged in the backrest 3, the air bag 7 passes through
Tracheae is connect with the air pump on pedestal 1, and the air pump and the tracheae junction are equipped with solenoid valve, the solenoid valve and controller
Connection, the controller and remote controler are wirelessly connected.User sends signal to controller by remote controler to control solenoid valve
Switch.
The solenoid valve includes solenoid valve body, and the solenoid valve body is equipped with cavity, and be connected to the cavity
Air intake 81, gas outlet 82 and exhaust outlet 83, the cavity is interior to be equipped with sliding plug 84, installs the mobile bar of the sliding plug 84
85, described 85 one end of mobile bar is connect with magnetic block 86, is additionally provided with magnetic plate 87 in the cavity, the magnetic plate 87 with it is described
Connecting spring 88 is equipped between magnetic block 86.
Air intake 81 is connect with air pump, and gas outlet 82 is connect with tracheae, and exhaust outlet 83 is connected to outside, when solenoid valve is beaten
Open, that is, be powered when, magnetic plate 87 due to coil and iron core effect generate magnetic force, magnetic block 86 compress connecting spring 88 after with magnetic
Suction disc 87 connects, to make mobile bar 85 that sliding plug 84 be driven to move up, will block between gas outlet 82 and exhaust outlet 83, this
When, the gas in air pump enters cavity by air intake 81, then enters tracheae to air bag by gas outlet 82.When solenoid valve closing, i.e.,
When no power, 87 magnetic force of magnetic plate disappears, and magnetic block 86 drives connecting spring 88 to reset by gravity, drives mobile bar 85
Sliding plug 84 moves down, and will block between gas outlet 82 and air intake 81, at this point, the gas in air bag enters sky by tracheae
Chamber, then be discharged by cavity through exhaust outlet 83.
