Description
Technical field
The utility model relates to a kind of metallic sheave support, specifically a kind of underframe pulley bracket that is used for seats such as old man's chair, office chair, leisure sofa, Massage sofa.
Background technology
Functional seats such as old man's chair now, office chair, leisure sofa, Massage sofa generally have the function that simple cylinder promotes rise and fall, but because these seat ordinary construction complexity, so be not easy to move and put, therefore top sheave is installed additional in the bottom of these seats in manufacturers, to move it, but this sat very steadyly seat originally and became with regard to order and slided easily, and order is sitting in top people and falls down or abnormal sitting posture easily, and it is impaired to make us body on the contrary.
Summary of the invention
The utility model relates to a kind of adjustable seat pulley bracket, and it utilizes lever principle, makes the seat can be so that can also firmly be placed on the ground when moving, and it is simple in structure, compact, and is cheap, is convenient to promote and use.
Technical solution of the present utility model is in original front wheel portion 1 and rear wheel portion 2, it is characterized in that being connected by toggle between front wheel portion 1 and the rear wheel portion 2, the roller arm of rear wheel portion 2 is provided with rotatable 90 ° spanner 3, and spanner 3 middle parts are provided with fixture block 4.
More than the pulley both sides of front wheel described in the utility model portion 1 be hinged with two inboards, front portion respectively at the rectangular frame bracket of lower floor of seat underframe 5, rear wheel portion 2 pulley both sides are hinged with two inboards, rear portion at the rectangular frame bracket of lower floor of seat underframe 5 respectively.
Advantage of the present utility model is to utilize lever principle, makes seat also can pack up pulley at any time so that can also firmly be placed on the ground when moving, and it is simple in structure, compactness and easy accessibility, and is cheap, is convenient to promote and use.
Description of drawings
Fig. 1 is a pulley bracket organigram of the present utility model;
Fig. 2 is the organigram of underframe of the present utility model and pulley bracket.
The specific embodiment
According to Fig. 1, shown in Figure 2, in original front wheel portion 1 and rear wheel portion 2, it is characterized in that being connected by toggle between front wheel portion 1 and the rear wheel portion 2, the roller arm of rear wheel portion 2 is provided with rotatable 90 ° spanner 3, and spanner 3 middle parts are provided with fixture block 4.The pulley both sides of described front wheel portion 1 are hinged with two inboards, front portion at the rectangular frame bracket of lower floor of seat underframe 5 respectively, and rear wheel portion 2 pulley both sides are hinged with two inboards, rear portion at the rectangular frame bracket of lower floor of seat underframe 5 respectively.
Pulley bracket can be by regulating spanner, thereby make pulley lift away from ground or fall to touching mutually with ground, make underframe so that seat support integral body is located ground or built on stilts, make seat be moved easily, concrete operations are as follows: spanner is adjusted to state perpendicular to the ground, fixture block is lived the rear wheel bar with kayser, the rear wheel bar overturn forward and drove rear wheel and routs up forward this moment, make rear wheel turn to forward with ground and contact from lifting away from the state of ground, rear portion with underframe is lifted away from ground then, simultaneously, under the effect of toggle, front wheel bar and rear wheel bar be upset forward together, up to toggle the front wheel masthead is lived, at this moment front wheel is along with the front wheel bar overturns forward, finally turn to contact with ground and the underframe front portion is lifted away from ground; After seat is moved to desired location, only need be with moving 90 ° of spanner counter rotation, this moment, the rear wheel bar did not have obstacle to drive rear wheel immediately to contrary direction upset, make rear wheel lift away from ground, under the effect of toggle, the front wheel bar also along with the upset of rear wheel bar, also makes front wheel lift away from ground, form the seat underframe at last and be seated on the ground, seat then can not at will move.
