Abstract
The utility model discloses a fixing mechanism for a base of a chair, comprising a lever, a connecting piece connected with the end of the lever, wherein the connecting piece is connected with a tubular rotating piece, the inner wall of which is provided with latches; a positioning rod is arranged inside the base; the left side and the right side of the positioning rod are provided with racks; the end of the lever is connected to an oscillating element and moves through the tubular rotating piece as the oscillating piece oscillates; the utility model is reasonable in structure and can fixed the oscillating piece at more angles; moreover, the utility model can be widely arranged inside the bases of chairs to fix oscillating elements in the bases.
Description
Technical field
The utility model relates to the fixed mechanism of a kind of seat base, particularly a kind of seat base.
Background technology
At present, a kind of novel seat has appearred on the market, this seat can be regulated the angle of inclination of backrest, thereby it is more comfortable that people are sitting on the seat, by a seat base is set at under-seat, backrest is linked to each other with swing component on the pedestal, utilize the swing of swing component to realize regulating the angle of inclination of backrest and the fixed mechanism in the pedestal and fix swing component backrest is fixed; There is its structure of fixed mechanism of a kind of seat base to comprise tommy bar, connecting rod that links to each other with tommy bar and the latch that is arranged on interlinking lever end, backstay is installed in pedestal, backstay is provided with a plurality of grooves, this backstay one end links to each other with swing component on the pedestal, when swing component is swung, backstay moves under the drive of swing component, by pulling in the groove that tommy bar inserts latch swing component swing component is fixed, the groove that the fixed mechanism of this structure is arranged on the backstay is limited, limited several angles that swing component can only be fixed on when fixing swing component like this can not satisfy user's demand.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, fixed mechanism that swing component can be fixed on a kind of seat base of more perspective.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of fixed mechanism of seat base, comprise tommy bar, be connected the connector of tommy bar end, described connector links to each other with the tubular rotation part, this tubular rotation part inwall is provided with latch, in pedestal, be provided with backstay, the left and right sides of described backstay is provided with tooth bar, and this backstay end is connected on the swing component and navigates within the tubular rotation part with the swing of swing component.
The beneficial effects of the utility model are: when regulating the angle of inclination of backrest, swing component drives the backstay motion, backstay navigates within the tubular connection, after backrest arrives suitable angle, pulling tommy bar makes coupled connector drive the rotation of tubular rotation part, the latch of its inwall combined with tooth bar on the backstay backstay is fixed when the tubular rotation part rotated, and swing component can be fixed on more perspective like this to satisfy people's demand.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the utility model is installed in the structural representation in the pedestal;
Fig. 2 is the broken away view of tubular connection and backstay;
Fig. 3 is a structure principle chart of the present utility model;
Fig. 4 is a structure principle chart of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of fixed mechanism of seat base, comprise tommy bar 1, be connected the connector 2 of tommy bar 1 end, described connector 2 links to each other with tubular rotation part 3, these tubular rotation part 3 inwalls are provided with latch 31, be provided with backstay 5 in pedestal, the left and right sides of described backstay 5 is provided with tooth bar 51, and these backstay 5 ends are connected on the swing component 4 and navigate within the tubular rotation part 3 with the swing of swing component 4; When regulating the angle of inclination of backrest, swing component 4 drives backstay 5 motions, backstay 5 navigates within the tubular connection 3, after backrest arrives suitable angle, pulling tommy bar 1 makes coupled connector 2 drive 3 rotations of tubular rotation part, the latch 31 of its inwall combined with tooth bar 51 on the backstay 5 backstay 5 is fixed when tubular rotation part 3 rotated, and backrest is fixed on the required angle of people.
With reference to Fig. 3, the latch 31 on the tubular rotation part 3 combines backstay 5 fixing with tooth bar on the backstay 5.
With reference to Fig. 4, tubular rotation part 3 rotates the latch 31 of back on it to be separated with tooth bar 51 on the backstay 5, and this moment, backstay 5 can navigate within the body of tubular rotation part 3.
The utility model is rational in infrastructure, swing component can be fixed on more perspective, extensively is installed in the detent mechanism that in the seat base swing component is played a kind of seat base of fixation.
