Abstract
The utility model discloses a driving extension bar device for fasteners, which is provided with a shell, and a worm gear and a worm which are engaged with each other are mounted in the shell, both ends of the worm are respectively extended out of the shell, and a driving extension bar, one end of which is extended out of the shell and which can rotate along with the worm gear, is mounted at the center of the worm wheel. A handle is arranged on the other side of the shell, which is opposite from the driving extension bar. By means of the conversion of the driving extension bar device, a pneumatic wrench which cannot directly cooperate with an ordinary direct extension bar for fastening due to the limitation of the fastener position in the past can be operated, the efficiency is increased, the man-hour is saved, and the production cost is reduced.
Description
Technical field
The utility model belongs to a kind of fastening means, especially a kind of securing member transmission extension bar device.
Background technology
At present generally use securing member transmission extension bar in the diesel engine industry, this transmission extension bar is direct bar, is used for cooperating with pneumatic impact wrench firmware tightly, and is very easy to use.But owing to be subjected to the restriction of diesel engine size, fastener locations, it is fastening that a lot of positions can't adopt pneumatic impact wrench to be undertaken by the transmission extension bar at all, adopts manually tightly, both increased man-hour, improved cost again.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of securing member transmission extension bar device that is not subjected to fastener locations restriction, can be used with pneumatic impact wrench.
For solving the problems of the technologies described above, this securing member transmission extension bar has a housing, the worm gear, the worm screw that mesh together are installed in the housing, and housing is stretched out at described worm screw two ends respectively, and described worm gear center is equipped with the transmission extension bar that stretches out housing with its rotation and an end.
As to improvement of the present utility model, on the housing of the relative opposite side of transmission extension bar, be provided with handle.
The both ends of described worm screw are provided with docking port.
After adopting said structure, can will limit by fastener locations, and can't adopt the ordinary straight extension bar directly to cooperate fastening situation with pneumatic impact wrench, by the conversion of this securing member transmission extension bar device, realize having improved efficient with the pneumatic impact wrench operation, save man-hour, reduced production cost.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a cross-sectional view of the present utility model;
The structural representation that Fig. 2 looks for Fig. 1 left side.
The specific embodiment
With reference to accompanying drawing, this securing member transmission extension bar device has a housing 1, the worm gear 4, the worm screw 2 that mesh together are installed in the housing 1, housing 1 is stretched out at worm screw 2 two ends respectively, be provided with bearing 5 between worm screw 2 and the housing 1, housing 1 two opposite outer corresponding to worm screw 2 positions is provided with bearing (ball) cover 3, is provided with docking port at the both ends of worm screw 2.The transmission extension bar 7 that stretches out housing 1 with its rotation and an end is installed at worm gear 4 centers, transmission extension bar 7 ends are provided with docking port, be used for assembly tool and connect direct bar, adopt key to be connected between transmission extension bar 7 and the worm gear 4, be provided with bearing 5 between transmission extension bar 7 and the housing 1, be provided with bearing (ball) cover 3 corresponding to housing 1 two opposite outer at transmission extension bar 7 positions.On the housing 1 of the relative opposite side of transmission extension bar 7, be provided with handle 6, be convenient to hand-held.
