Description

Spacing clock spring

Technical Field

The utility model relates to the technical field of clock springs, in particular to a limit clock spring.

Background

The clock spring is located between the sensor control portion and the air bag in the airbag system and is a key component of the safety system.

The clock spring is electrically connected with the inside of the clock spring through a flat cable, so that the safety airbag can still be connected with the inside of the circuit when the steering wheel rotating wire is pulled; however, the prior art has the following disadvantages: when the prior clock spring is used, the internal coil of the clock spring is not provided with a practical limiting structure after being stretched to limit the connecting wire, after the steering wheel rotates, the internal connecting wire is still in the last stretched state, and after the steering wheel rotates in the opposite direction continuously, the internal connecting wire of the clock spring is easy to break due to the fact that the internal connecting wire is broken, and the like, so that a circuit is disconnected.

Disclosure of Invention

The utility model mainly aims to provide a limit clock spring, which has the function of limiting and resetting by rotating a torsion spring to retract a screwed-out connecting wire, so that the problem in the background technology can be effectively solved.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a spacing clock spring, includes the top cap, top cap joint forms complete swivelling joint ware on the base, top cap bottom department fixedly is provided with the fixed axle in the middle, the lateral wall of fixed axle and the one end looks joint of torsional spring, the opposite side joint of torsional spring is inside the fixed shell that the inside center of base was seted up, the mounting groove has been seted up to the fixed shell inside, just the fixed axle link up in the mounting groove with the torsional spring, twines in the fixed axle periphery through the torsional spring to make after the steering wheel rotates, the inconvenient reset of inside clock spring, thereby lead to the condition that life reduces, the connecting wire that withdraws the spiral-out is revolved through the torsional spring makes clock spring obtain spacing reset's function.

Further, the torsion spring is sleeved on the periphery of the fixed shaft, and the space position of the torsion spring is fixed through the fixed shaft.

Further, the outer side wall surface of the base is fixedly connected with an installation clamping plate for enabling the whole shell to be fixed in position, and the installation position of the device is fixed through the installation clamping plate.

Further, a plurality of clamping pieces used for being clamped in the steering wheel handle are fixedly connected to the bottom end of the base respectively, and the device is fixed in an auxiliary mode through the clamping pieces.

Further, a connecting wire is wound inside the base, one end of the connecting wire, which is fixed in the base, penetrates through the fixed shell and is connected with the fixed shaft, and other circuit structures are connected through the connecting wire.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the torsion spring is wound on the periphery of the fixed shaft, so that the clock spring in the steering wheel is inconvenient to reset after the steering wheel rotates, the service life is reduced, and the clock spring is limited by the rotary retraction of the torsion spring through the rotary retraction of the rotary connection wire.

Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1-3, a spacing clock spring, including top cap 1, top cap 1 joint forms complete swivelling joint ware on base 2, top cap 1 bottom department fixedly is provided with fixed axle 4 in the middle, the lateral wall of fixed axle 4 and the one end looks joint of torsional spring 5, the opposite side joint of torsional spring 5 is in the inside fixed shell 6 that the inside center of base 2 was seted up, the mounting groove 7 has been seted up to fixed shell 6 inside, and fixed axle 4 and torsional spring 5 link up in mounting groove 7, twine in fixed axle 4 periphery through torsional spring 5, thereby make after the steering wheel rotates, the inconvenient reset of inside clock spring, thereby lead to the condition that life reduces, receive the function of spacing that makes clock spring obtain through torsional spring 5 gyration and withdraw the connecting wire 8 of screwing out.

As shown in the figure, the periphery of fixed axle 4 is located to torsional spring 5 cover, the fixed mounting cardboard 3 that is used for making whole shell fixed position of base 2 lateral wall fixedly connected with, base 2 bottom is fixedly connected with respectively a plurality of joint spare 9 that are used for the joint in the steering wheel handle, the inside winding of base 2 has a connecting wire 8, and the one end of connecting wire 8 being fixed in base 2 is passed fixed shell 6 and is connected with fixed axle 4, connect other circuit structures through connecting wire 8, assist the fixed this device through joint spare 9, fix the position of this device installation through mounting cardboard 3, fix the spatial position of torsional spring 5 through fixed axle 4.
