Description
Technical Field
The utility model relates to a seat metal framework with adjustable waist is leaned on.
Background
The waist on the metal framework seat is transferred, does not have the function of adjusting from top to bottom usually, can not adapt to the user of height or position of sitting difference in a flexible way, has reduced the travelling comfort or has the waist that sets up comparatively complicacy and leans on adjustment mechanism, and high in manufacturing cost just uses the reliability low.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the defect that the back of the seat of metal framework lacks simple adjustable mechanism among the prior art, provide a seat metal framework with adjustable waist is leaned on.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a seat metal framework with adjustable waist is leaned on, leans on including metal framework body and waist, is fixed with the guide rail on the metal framework body, and the surface of guide rail is undulant wave, and the both ends that the waist leaned on are provided with the mounting panel that has hollow out construction, and the end of mounting panel is provided with a plurality of wave protrudingly, and the waist is leaned on through the mounting panel insert the guide rail of metal framework body both sides after, the protruding card of wave on the mounting panel is gone into in the guide rail, with the trough tight fit on.
Furthermore, the guide rail comprises a front guide rail and a rear guide rail, the front guide rail and the rear guide rail are locked through screws, the wavy guide rail surface is in a C-shaped groove shape, and the notch of the C-shaped groove is smaller than the length of the mounting plate.
Furthermore, the metal framework body is provided with a mounting hole of the guide rail, and the back of the guide rail is fixed on the metal framework body through a rivet.
Furthermore, the waist rest is made of materials with certain elasticity.
Furthermore, the material of guide rail is PA66, and the material of waist leans on is PP.
Furthermore, the number of the wavy bulges on the mounting plate is 2-6.
The utility model discloses the beneficial effect who reaches is: the utility model discloses both ends that lean on at the waist are provided with the mounting panel that has hollow out construction, and the end of mounting panel is provided with a plurality of wave protrudingly, and the design of fretwork can be guaranteed to have elasticity when mounting panel and guide rail wave cooperation chucking, guarantees under the effect that receives the external force that the waist leans on and more reciprocates on the wave guide rail, can not have the dead sensation of card, adjusts the comfort when the waist leans on from top to bottom in the promotion.
Drawings
