Abstract
The utility model relates to a seat with angles of a seat back rack and a seat rack capable of being adjusted, and particularly relates to a twisting return device for assembly of a seat angle adjustor, the device comprises a supporting plate, a twisting lever, a working shaft, and a limiting concave block, the working shaft is horizontal, and covered by a working shaft sleeve, the twisting lever is connected on the working shaft, and the limiting concave block is disposed near the twisting lever, the twisting return device in the utility model is characterized in that, the device also comprises a return spring, a spring projection, and a shaft sleeve block; the shaft sleeve block is disposed on the working shaft sleeve; the return spring is disposed on the working shaft, one end is connected with the shaft sleeve block, and the other end of the return spring is connected with the spring projection, and the spring projection is disposed at one end of the working shaft. The beneficial effects of the twisting return device are in that: via addition of the return spring, translation of the working shaft, parts, and the twisting lever to initial positions is automatically realized via return force during compression of the spring.
Description
Technical field
The utility model relates to the seat of a kind of chair back rack and chair seat frame adjustable angle, relates in particular to a kind of seat angle adjustor stack-mounted twisting return mechanism that is used for.
Background technology
Present automotive seat all have the function of freely adjusting the chair back, and when people pressed the handle of seat angle adjustor and the chair back applied certain external force, the chair back just can recede to reach the chair back angle of people's demand; And when people need recall to initial state with the chair back, only need press the handle of seat angle adjustor once more and keep the chair back to be the stressed state of nature, the chair back just can be replied.Seat angle adjustor generally is made up of chair back gusset piece, seat support gusset piece, core members, handwheel or regulating handle etc., and core members is connected with the seat support gusset piece with chair back gusset piece respectively.In the practical application; Need embed necessary parts to core members; The rotation of the twisting lever through being fixed on working shaft can realize the rotation of working shaft; The twisting lever is stuck in the spacing recessed translation of locating to realize working shaft, and the tip of the axis of working is connected with necessary parts, embeds in the core members also locked through realizing the necessary parts of an once rotation and a translation; After unclamping the twisting lever; Parts discharge from core members; The torsion that has after the parts rotation makes parts and working shaft opposite spin to initial angle; There is a kind of problem in this technical scheme: can not realize that working shaft, parts, twisting lever move to initial position automatically, need to rotate once more the twisting lever to initial position.
The utility model content
The purpose of the utility model is to overcome above-mentioned defective; A kind of seat angle adjustor stack-mounted twisting return mechanism that is used for is provided; After parts embedded core members and unclamp the twisting lever, this device can realize automatically that working shaft, parts, twisting lever move to initial position.
For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: be used for seat angle adjustor stack-mounted twisting return mechanism, comprise stay bearing plate, twisting lever, working shaft, spacing recessed, working shaft is a level; Working shaft is by work axle sleeve parcel; The twisting lever is connected on the working shaft, spacing recessed next door that is positioned at the twisting lever, and it is characterized in that: this device also comprises returning spring, spring projection, axle sleeve piece; The axle sleeve piece is positioned at working shaft and puts; Returning spring is positioned on the working shaft, and an end is connected with the axle sleeve piece, and the other end is connected with the spring projection, and the spring projection is positioned at an end of working shaft.
The axle sleeve piece is positioned at working shaft and puts, and working shaft is by work axle sleeve parcel, and when working shaft rotated or moves, the work axle sleeve was motionless, and the axle sleeve piece is also motionless.
Rotate the twisting lever, drive working shaft and rotate together; Rotation twisting lever is again located its card to spacing recessed, the working shaft translation, and the also translation of spring projection on the working shaft, because the other end of spring is fixed, returning spring is compressive state; The other end of working shaft is connected with parts, and through realizing once a rotation and a translation, parts embed in the core members also locked; After parts embed core members; Unclamp the twisting lever; Parts break away from core members, and parts torsion makes parts and working shaft opposite spin to initial angle, and the returning spring of compression has restoring force in this device; The axle that pushes the work forward moves to initial position, and parts, twisting lever are also got back to initial position simultaneously.
The beneficial effect that the utlity model has is: through adding returning spring, the restoring force that has when utilizing length of spring compressed realizes that automatically working shaft, parts, twisting lever move to initial position.
Description of drawings
Fig. 1 is the side-looking structural representation of the utility model;
Fig. 2 is the structural representation of facing of the utility model.
Wherein, 1 twisting lever, 2 spring projections, 3 axle sleeve pieces, 4 stay bearing plates, 5 working shafts, 6 returning springs, 7 spacing recessed.
The specific embodiment
Figure is the preferred embodiment of the utility model, below in conjunction with accompanying drawing the utility model is further described: wherein, and 1 twisting lever, 2 spring projections, 3 axle sleeve pieces, 4 stay bearing plates, 5 working shafts, 6 returning springs, 7 spacing recessed.
Referring to Fig. 1 and Fig. 2; Be used for seat angle adjustor stack-mounted twisting return mechanism, comprise stay bearing plate 4, twisting lever 1, working shaft 5, spacing recessed 7, working shaft 5 is a level; Working shaft 5 is by work axle sleeve (not shown) parcel; Twisting lever 1 is connected on the working shaft 5, spacing recessed 7 next door that is positioned at twisting lever 1, and it is characterized in that: this device also comprises returning spring 6, spring projection 2, axle sleeve piece 3; Axle sleeve piece 3 is positioned at working shaft and puts; Returning spring 6 is positioned on the working shaft 5, and an end is connected with axle sleeve piece 3, and the other end of returning spring 6 is connected with spring projection 2, and spring projection 2 is positioned at an end of working shaft 5.
Axle sleeve piece 3 is positioned at working shaft and puts, and working shaft 5 is by work axle sleeve parcel, and when working shaft 5 rotated or be mobile, the work axle sleeve was motionless, and axle sleeve piece 3 is also motionless.
Rotate twisting lever 1, drive working shaft 5 and rotate together; Rotation twists lever 1 again; To spacing recessed 7 place's (see figure 1), working shaft 5 is to the direction translation away from spring projection 2 with its card, the also translation of spring projection 2 on the working shaft 5; Because the other end of returning spring 6 is fixed in axle sleeve piece 3, so returning spring 6 is compressive state; The other end of working shaft 5 is connected with parts (not shown), and through realizing once a rotation and a translation, parts embed in the core members also locked; After parts embed core members; Unclamp twisting lever 1; Parts break away from core members, and parts torsion makes parts and working shaft 5 opposite spins to initial angle, and the returning spring 6 of compression has restoring force in this device; The axle 5 that pushes the work forward moves to initial position, and drive parts, twisting lever 1 are also got back to initial position.
This device is through adding returning spring, and the restoring force that has when utilizing length of spring compressed realizes that automatically working shaft, parts, twisting lever move to initial position.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
