Abstract
The utility model relates to a steering wheel angle adjusting mechanism in a direction system, in particular to a return spring fixing device. A return spring is placed between an adjusting support and a supporting shell frame. A boss is arranged on a lower portion supporting plate of the adjusting support. The lower end of the return spring is sleeved on the boss. The upper end of the return spring abuts against on the lower plate face of a bottom plate of the supporting shell frame. A limiting part for limiting the upper end of the return spring so that the upper end of the return spring cannot move freely is arranged on the bottom plate of the supporting shell frame. Due to the arranged limiting part, the fact that the two ends of the return spring are constrained and limited is achieved, free moving of the return spring is avoided, even if a locking mechanism is in a loosening state, the two ends of the return spring are in a constrained state, and falling-off phenomena cannot happen.
Description
Technical field
The utility model relates to the steering wheel angle regulating mechanism in the direction system.
Background technology
At present, in known technology, in order to improve the driving attitude, can design adjustable seat, and the bearing circle that can regulate is provided, satisfy the individual sexual demand of chaufeur by the adjusting of seat and bearing circle.In the angle adjusting mechanism of bearing circle, mainly comprise the overarm brace that links to each other with the instrument calibration crossbeam, overarm brace is provided with regulates the angular adjustment matching mechanism that the holder shell that is connected on support and the Steering gear is configured to Steering gear, and for the catch gear that both are locked or loosen, and can adjust the angle of bearing circle when opening regulating handle, angular adjustment during to correct position the turn regulating handle this positional lock is fastened.In above-mentioned regulating mechanism, regulate between support and the holder shell frame pull back spring is set, the elastic force that is pull back spring becomes to making holder shell frame upwards to prop up together with Steering gear, gripping bearing circle rotation Steering gear can make bearing circle be in the position of suitable driving, regulating handle enforcement locking is rotated in the angle position adjustment of bearing circle and Steering gear suitably back, and the position of this bearing circle is just determined.
The two ends up and down of pull back spring abut on the upper face of the supporting plate of regulating support respectively and on the lower surface of the base plate of holder shell frame in the said structure, lower surface at base plate has a upwards blind hole of indent, the upper end of pull back spring is exactly to be positioned at this blind hole place, in the parts fitting process, the operating personal custom is carried the regulating handle of carrying catch gear, may cause release namely to regulate support and be in the state that can rotate arbitrarily with holder shell frame, the upper end of pull back spring just is in no restrained condition like this, so just easy dropping very of pull back spring.
Summary of the invention
The purpose of this utility model provides a kind of anchor fitting of effectively avoiding the pull back spring that pull back spring drops.
For achieving the above object, the utility model has adopted following technical scheme: a kind of anchor fitting of pull back spring, pull back spring is being regulated between support and the holder shell frame, the lower pallet of regulating support is provided with boss, the lower end of pull back spring is set on the boss, it is characterized in that: the upper end of described pull back spring is resisted against on the lower face of the base plate that holds in the palm the shell frame, and the base plate of holder shell frame is provided with any mobile limiting section in upper end that the constraint pull back spring arrives.
Owing to be provided with limiting section, realized that the constraint at pull back spring two ends is spacing, avoided any movement of pull back spring, although catch gear is in the state of getting loose, the two ends of pull back spring also will be in restrained state, the phenomenon that drops can not occur.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the perspective view of the utility model confined state.
The specific embodiment
Referring to Fig. 1, a kind of anchor fitting of pull back spring, pull back spring 10 is being regulated between support 20 and the holder shell frame 30, the lower pallet 21 of regulating support 20 is provided with boss 211, the lower end of pull back spring 10 is set on the boss 211, the upper end of described pull back spring 10 is resisted against on the lower face of the base plate 31 that holds in the palm shell frame 30, and the base plate 31 of holder shell frame 30 is provided with any mobile limiting section in upper end of constraint pull back spring 10.In the such scheme, the upper/lower terminal of pull back spring 10 by reliably in addition spacing constraint live, in the parts fitting process, no matter whether the assembly crewman carries the regulating handle of carrying catch gear, pull back spring 10 is all limited by failure-free, the generation of the phenomenon of having avoided dropping because getting loose.
Described limiting section comprises on the base plate 31 one the upwards blind hole 32 of indent, and the middle part is provided with and points to the positioning boss 33 of regulating boss 211 1 sides on the support 20 at the bottom of the hole of blind hole 32, and positioning boss 33 is inserted to the upper end of pull back spring 10.Like this by the cooperatively interacting of blind hole 32 and positioning boss 33, the upper end of pull back spring 10 has just been lived by fixed constraint reliably.
As preferred version, described positioning boss 33 is tubbiness, connecting bore is arranged at the bottom of its barrel, and tapped bore is offered in the bottom, hole of blind hole 32, and screw 34 is connected as a single entity at the bottom of the hole with the positioning boss 33 of tubbiness and blind hole 32.Adopt screw 34 that positioning boss 33 is realized being connected with the base plate 31 at blind hole 32 places, operation of components is convenient, and the reliability of connection is also guaranteed.
In order to ensure reliably, fill up at the barrel end of the ailhead of described screw 34 and positioning boss 33 and be provided with pad 35, as shown in Figure 2.
