Detailed Description
The manual actuator of the functional sofa stretching device of the present invention will be further described with reference to fig. 1 to 3.
A functional sofa stretching device comprises a pedal mechanism 1, a cushion mechanism 2, a backrest mechanism 3 and a manual execution mechanism, wherein the pedal mechanism 1, the cushion mechanism 2 and the backrest mechanism 3 are all the prior art, and detailed description is not provided in the application. The manual actuating mechanism comprises a driving rod 8, a linkage rod 6 and an actuating rod 9. The front end of the driving rod 8 is hinged on one connecting rod 12 in the pedal mechanism 1 of the sofa; the two ends of the linkage rod 6 are respectively a swing end and a hinged end, as shown in fig. 1, the front end is the hinged end, and the rear end is the swing end. The hinged end is hinged to the cushion mechanism 2 of the sofa, and the swinging end can swing and is hinged with the rear end of the driving rod 8; the utility model discloses a sofa, including actuating lever 9, middle articulated position, trigger end and execution end, middle articulated position articulates on the cushion mechanism 2 of sofa, trigger and have on the end and can support the trigger part 91 in actuating lever 8 rear end, this trigger part 91 is for being fixed in the locating pin on the actuating lever 9 trigger end, be connected with cable 92 on the execution end to drive actuating lever 9 and rotate.
The manual actuating mechanism further comprises a limiting column 7 and a tension spring 5, wherein the limiting column 7 is fixed on a cushion mechanism of the sofa and is supported by the linkage rod 6, so that the upward swinging range of the linkage rod 6 is limited; the two ends of the tension spring 5 are hooked on the cushion mechanism 2 and the driving rod 8 of the sofa respectively to pull the linkage rod 6 to be supported on the limiting column 7, so that the stability of the whole sofa is guaranteed.
The linkage rod 6 is provided with a connecting plate 61, and the connecting plate 61 is connected with the linkage rod 11. When the manual actuators are assembled in the sofa, two groups of manual actuators need to be symmetrically arranged, so that the linkage rod 11 can synchronize the actions of the two groups of manual actuators to ensure the stability of operation.
The rear end of the driving rod 8 has an extension 81 against which the trigger member 91 abuts. Specifically, the extension portion 81 extends backward relative to the driving rod 8, that is, extends to the lower side of the trigger part 91, so that when the trigger part 91 rotates downward, the extension portion 81 can abut against the extension portion 81 to drive the driving rod 8 to rotate synchronously, thereby driving the pedal mechanism 1 to unfold.
The cushion mechanism 2 is provided with a positioning tube 21 for the stay cable 92 to pass through, one end of the stay cable 92, which is back to the actuating rod 9, passes through the positioning tube 21 and then extends to the outer side of the sofa and is connected with a handle, so that a user can pull the stay cable, the positioning tube 21 can play a role in limiting the stay cable 92, and the problem that the stay cable 92 is wound with other components in the sofa stretching device is solved.
It should be noted that the hinge joints in the present embodiment are implemented by pin rods and corresponding hole positions.
Based on the structure, the utility model discloses can be general with electric putter, can directly replace the electric putter in the electronic class sofa, consequently can select the installation at electronic class and manual class before the installation. Can select to pack into the utility model discloses realize manual drive, also can pack into electric putter and realize electric drive, same extension device can be fit for manual actuating mechanism and electric putter's installation drive simultaneously, is showing and is reducing manufacturing cost. When the pedal mechanism is used specifically, the pulling cable 92 is pulled, the executing rod 9 rotates counterclockwise, the triggering end drives the triggering part 91 to rotate downward, the triggering part 91 is pressed on the extending part 81 of the driving rod 8 to drive the rear end of the driving rod 8 to rotate around the hinged end of the linkage rod 6, namely, the linkage rod 6 can swing forward, so that each connecting rod 12 in the pedal mechanism 1 is driven to expand relatively, and the opening function of the stretching device is realized.
As shown in fig. 3, in the furled state, after the connecting line 43 between the hinge holes 41 and 42 at the front end and the rear end of the driving rod 8 is pulled through the hole 61 at the hinge end of the linking rod 6, the rear end of the driving rod 8 has potential energy rotating upward under the driving of the tension spring 5, so that the upper side position of the linking rod 6 abuts against the limiting column 7 in the state to play a role in locking, and the structure is stable.
In this embodiment, the pedal mechanism 1 is retracted by an external force to allow the manual actuator to reach the locked position.
