Abstract
The invention discloses an inflatable-shaft key bar positioning device which comprises an inflatable shaft and a key bar. The key bar is tightly fastened on the inflatable shaft through a threaded fastening component. The key bar of the inflatable shaft can be effectively fastened, slipping of the key bar is avoided, air in the shaft can be increased, an airbag is conveniently mounted, and convenience and efficiency are effectively improved.
Description
Technical field
The present invention relates to a kind of inflatable axle key bar positioning device.
Background technology
At present, the key bar of existing air-expanding shaft all carries out link by the mode that draw point is fixing, and draw point is inserted through key bar and air-expanding shaft, it easily comes off or breaks in key bar, makes the easy slippage of key bar, falls, waste time and energy when making to retighten, thus be difficult to air-expanding shaft air bag is installed.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of inflatable axle key bar positioning device, effectively ensureing that key bar is fixed, effectively improving the efficiency of installation process.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of inflatable axle key bar positioning device, comprise air-expanding shaft and key bar, described key bar is fastened on air-expanding shaft by threaded fastener assembly.
As the improvement of technique scheme, described threaded fastener assembly includes bolt and fastener, and the corresponding described bolt of described fastener is provided with screw, and bolt thread is connected on described air-expanding shaft.
As the further improvement of technique scheme, described fastener is provided with the plectrum of V-type.
Further, be provided with support between described key bar and threaded fastener assembly, described support is provided with through hole.
Further, described Bracket setting becomes C type, leaves the space of dodging described key bar in support.
The invention has the beneficial effects as follows: this product can the key bar of effective fastening air-expanding shaft, avoids the slippage of key bar and thinks, and can also increase space in week, conveniently installing air bag, thus effectively improving convenience and efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is mounting structure schematic diagram of the present invention.
Detailed description of the invention
With reference to Fig. 1, a kind of inflatable axle key bar positioning device of the present invention, comprise air-expanding shaft 1 and key bar 2, described key bar 2 is fastened on air-expanding shaft 1 by threaded fastener assembly.
As the improvement of above-mentioned embodiment, described threaded fastener assembly includes bolt 3 and fastener 4, and the corresponding described bolt 3 of described fastener 4 is provided with screw, and bolt 3 is threaded on described air-expanding shaft 1.
Further, described fastener 4 is provided with the plectrum 41 of V-type.
Further, between described key bar 2 and threaded fastener assembly, be provided with support 5, described support 5 is provided with through hole.
Preferably, C type is arranged to by described support 5, leaves the space of dodging described key bar 2 in support 5.
The above, just better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, all should fall within protection scope of the present invention.
