Smaller, usually backrest frames are limited in skeleton clamping necking groove in standing shape, it is necessary to when backrest frames folding is got up, forward
Backrest frames are promoted just can easily to rotate backrest frames after overcoming the elasticity constraint of skeleton clamping necking groove so as to by backrest bone
Frame folding is got up.
The notch of above-mentioned skeleton clamping necking groove is set forward, and the front portion of two elastic clamping sheets bends inwards respectively
Card-tight part is formed, the forward edge of the card-tight part distinguishes outward bending and extends to form resigning guide part.Pushed away using this design
It can smoothly be entered during the erecting of dynamic backrest frames by resigning guide part in skeleton clamping necking groove.
The rear portion of two elastic clamping sheets is connected with same connecting plate, and the connecting plate is fixedly mounted on the clamping
The bottom land of piece mounting groove.Disposably two elastic clamping sheets can be installed in place by connecting plate using this design.
Limited step is provided with the clamping sheet mounting groove below above-mentioned connecting plate, the lower edge of the connecting plate abuts
On the limited step.Installation positioning can be carried out by limited step using during this design and installation elastic card.
The rear of above-mentioned backrest frames is provided with skeleton limiting plate, and the bottom of the skeleton limiting plate is fixed with the base to be connected
Connect, the top of the skeleton limiting plate is pushed against on the backrest frames.Can be to backrest frames using this scheme skeleton limiting plate
Backward motion play spacing effect, prevent backrest frames by transition push collide rear other people or thing.
The outer wall of above-mentioned skeleton limiting plate is provided with reinforcement.
Two elastic clamping sheets and the connecting plate are integrally formed.Production had not only been facilitated using this design but also conveniently pacified
Dress.
Beneficial effect：Using the beneficial effects of the utility model be due to skeleton clamping necking groove notch it is smaller, usually
Backrest frames are limited in skeleton clamping necking groove, it is necessary to when backrest frames folding is got up in standing shape, promote backrest forward
Skeleton just can easily rotate backrest frames so as to which backrest frames folding be risen after overcoming the elasticity constraint of skeleton clamping necking groove
Come, this structure and traditional angle modulation electrical equipment structure compared are simple lightly, cost is cheap.
