Description
Technical field
The present invention relates to sofa frame technical field, is especially a kind of high-comfort durable type sofa frame.
Background technology
Sofa frame is the important component of sofa, and sofa is using sofa frame as skeleton, made of outer cladding mat, so
And the backrest of sofa frame on the market is mostly fixed, angle can not be adjusted, so in actual use, due to using
The build of object is different, and fat or thin to differ, the more fat people of build is sitting on sofa, and center of gravity can be earlier, and body line up is not opened, and relaxes
Adaptive is poor.
The content of the invention
The technical problems to be solved by the invention are the defects of overcoming prior art, there is provided a kind of sofa frame, this sofa frame
Back rest angle of inclination can be changed according to the pressure being subject to, so as to improve comfortableness.
In order to solve the above technical problems, the present invention proposes a kind of high-comfort durable type sofa frame, including chassis, on chassis
Provided with the fixed mount for placing cushion, the back sweep of fixed mount is provided with back rest, and middle part and the chassis of back rest pass through
Rotating shaft is rotatably connected, and the scope of activities of the back rest is limited by position-limit mechanism, and back rest has the outer end extended outside chassis
With the inner extended in chassis, the first elastic support member, the first resilient support portion are provided between the outer end of back rest and chassis
Part includes the first supporting sleeve, the first spring and the first supporting post-rod, and one end of first supporting sleeve is connected with/chassis,
The other end of first supporting sleeve is provided with one end dress of the first axial hole, first spring and first supporting post-rod
Enter in first axial hole, the other end of first supporting post-rod is connected with back rest；The inner of back rest and fixed mount
Between be provided with the second elastic support member, the second elastic support member includes the second supporting sleeve, second spring and the second support
Push rod, one end of the second supporting sleeve are connected with fixed mount, and the other end of the second supporting sleeve is provided with the second axial hole, the second bullet
One end of spring and the second supporting post-rod loads in the second axial hole, and the other end of the second supporting post-rod is connected with back rest.
After said structure, compared with prior art, the present invention has advantages below：By in the outer end of back rest and
The inner sets the first elastic support member and the second elastic support member respectively, in actual use, by user to backrest
Frame applies pressure backward, back rest is rotated backward around the shaft, and compresses the first elastic support member and the second resilient support
Part, according to the size of user's pressure applied, the regulation to back rest different angle is realized, allow the user that build is larger
Backward by that center of gravity can be made to offset backward, and bigger extending space is obtained, so as to improve comfortableness, after user leaves,
The pressure being applied on back rest removes, the first spring and second in the first elastic support member and the second elastic support member
The elastic reset of spring so that back rest returns to original position.
As an improvement, it is used for the first drag reduction structures for reducing frictional force between the first supporting sleeve and the first supporting post-rod,
First drag reduction structures include the first stopper slot on the first supporting post-rod outer wall, axially extend and be arranged at the first support set

A part for ball is located in first stopper slot, and another part is located in first limit sliding chutes；Second supporting sleeve
It is used for the second drag reduction structures for reducing frictional force between the second supporting post-rod, the second drag reduction structures include being located at second support
The second stopper slot on bar outer wall, axially extend be arranged on the second supporting sleeve inwall the second limit sliding chutes, located at
The second ball between two supporting sleeves and the second supporting post-rod, a part for second ball are located at second stopper slot
Interior, another part is located in second limit sliding chutes, so, when the first elastic support member and the second elastic support member exist
During expanding-contracting action, supporting sleeve and the friction of supporting post-rod between the two are rolling friction, and frictional force is smaller, and elastic telescopic acts more
Add it is smooth, with this ensure the first elastic support member and the second elastic support member action reliability and stability.
As an improvement, the front end of chassis is provided with the support frame for being used for supporting foot, upper end and the fixed mount of support frame are hinged,
The drive device for driving support frame to be rotated around hinged place is provided with the chassis, drive device is included inside chassis
Installing plate, be obliquely installed cylinder on a mounting board, be used for the connection member that connects cylinder rod located at the support frame back side, connection
Prolong its length direction on part and be provided with mounting groove, be provided with the two side of mounting groove and slided with the installation of its equidirectional setting
Groove, the cylinder rod of cylinder are stretched into mounting groove and by that slip can connect relatively through the bearing pin in two installation chutes and connection member
Connect, so, can easily control the rotational angle of support frame by cylinder, under normality, cylinder shrinks completely, and support frame stops
With fixed mount substantially vertical position, when cylinder starts, stretch and promote support frame around hinged place rotate, it is complete in cylinder
Just support frame is in the position with fixed mount same level height when trailing, and cylinder is during contraction and stretching, extension, pin
Axle slides in installation chute and drives support frame to rotate, and the structure relative simplicity of above-mentioned drive device, saves to a certain extent
Cost has been saved, and ensure that using effect.
As an improvement, the quantity of drive device is two, it is symmetricly set on chassis, so, is driven using bilateral synchronous,
Performance when using support frame is more stable, while also improves the bearing capacity of support frame.
As an improvement, support frame is provided with stiffener plate, the connection member is fixed in stiffener plate, so, connection
The fixation of part is more firm.
As an improvement, position-limit mechanism includes position-limited rack and spacer pin, position-limited rack is fixed on the chassis/back rest, its
The spacing hole of circular arc is provided with, corresponding, spacer pin is fixed on the back rest, and the spacer pin stretches into the spacing hole
It is interior, so, the angle of back rest rotation is limited by spacing hole, when back rest is in original position, spacer pin is in spacing
The front end in hole, when back rest turns to maximum angle, spacer pin is in the rearmost end of spacing hole, summary, such a limit
The structure of position mechanism simplifies, and reliability is high, beneficial to long-term use.
