Abstract
The utility model relates to a telescopic elastic ring for straps provided for using the elastic oscillation buffering theory to reduce the burden of the carrying person, comprising a fixing seat, a sliding seat, an elastic telescopic structure and a panel, wherein, the fixing seat is in the shape of a channel steel whose top end is formed into a fastening slot; both side plates are hinged with buckled plywood on the fastening slot whose lower part is provided with a fixing sheet and a fixing hook; the bottom of the fixing seat is provided with a convex stop flange; the sliding seat is a hollow casing whose top end is provided with a convex end plate with a through hole and other end is formed into the fastening slot; both side plates are hinged with the buckled plywood on the fastening slot; the sliding seat is arranged in the fixing seat; the size of the end plate of the sliding seat is larger than the size of the opening of the stop flange of the bottom of the fixing seat; the elastic telescopic structure is provided with a fixing plate and springs whose one end is fixed on the fixing plate and other end passes through the through hole of the end plate of the sliding seat and is arranged in the hollow cavity of the sliding seat and fixedly connected with the hollow cavity; the fixing plate is clamped on the fixing sheet and the fixing hook of the fixing seat to make the fixing seat 1 and the sliding seat 2 form a sliding connection through the elastic telescopic structure 3; the panel is arranged on the opening of the front side of the fixing seat to make the sliding seat arranged in the fixing seat stably and slide in respect to the fixing seat.
Description
The utility model belongs to the bag bag and uses part, and particularly a kind of braces is with stretching the withdrawal force ring.
Children bear heavy school bag since the childhood and go to school now, and the weight of school bag is growing on and on.Used school bag braces does not provide the buffer structure of appropriate cushion effect, causes the school bag total weight to be applied to fully on children's shoulder, has had a strong impact on the children's torso healthy development.
The purpose of this utility model is to utilize similar porter to use rubber-like shoulder pole load to choose the oscillation buffer principle that load can alleviate heavy burden, and the braces that a kind of heavy burden person of alleviating load is provided is with stretching the withdrawal force ring.
The utlity model has holder, slip base, elastic telescopic structure and panel.Holder is channel steel shape, and its top forms buckling groove, articulated buckling plate on buckling groove place biside plate, and the buckling groove below is provided with stator and stay hook, and the holder bottom has the backstop limit of protrusion; Slip base is a hollow housing, and its top has the end plate of the band through hole of protrusion, and its other end forms buckling groove, articulated buckling plate on buckling groove place biside plate, and slip base places in the holder, and its end plate size is greater than the bore size on backstop limit, holder bottom; The elastic telescopic structure has fixed head and an end and is fixed on spring on the fixed head, the other end of spring passes through hole on the slip base end plate and places in the slip base cavity and with it and fixedly connected, fixed head is stuck on the stator and stay hook of holder, holder 1 is constituted through elastic telescopic structure 3 with slip base 2 be slidingly connected; Panel is installed in holder front openings place, and slip base stably is installed in the holder, and can the slippage of relative fixed seat.
Owing to the utlity model has holder, slip base, elastic telescopic structure and panel.Holder is channel steel shape, and its top forms buckling groove, articulated buckling plate on buckling groove place biside plate, and the buckling groove below is provided with stator and stay hook, and the holder bottom has the backstop limit of protrusion; Slip base is a hollow housing, and its top has the end plate of the band through hole of protrusion, and its other end forms buckling groove, articulated buckling plate on buckling groove place biside plate, and slip base places in the holder, and its end plate size is greater than the bore size on backstop limit, holder bottom; The elastic telescopic structure has fixed head and an end and is fixed on spring on the fixed head, the other end of spring passes through hole on the slip base end plate and places in the slip base cavity and with it and fixedly connected, fixed head is stuck on the stator and stay hook of holder, holder 1 is constituted through elastic telescopic structure 3 with slip base 2 be slidingly connected; Panel is installed in holder front openings place, and slip base stably is installed in the holder, and can the slippage of relative fixed seat.During use braces one end is installed in the buckling groove of holder and with the buckling plate chucking, the other end of braces is installed in the buckling groove of slip base and and tightens with buckling plate.When takeing on back of the body braces, heavy burden person bears a heavy burden when advancing, nationality helps knapsack inertia and weight, make the slip base relative fixed seat that is connected with holder through the elastic telescopic structure do flexible slippage, form back forced oscillation, reach the buffering effect that reduces vibration force, make knapsack comfortable and laborsaving when bearing, thereby reach the purpose of this utility model.
