Abstract
The utility model discloses an exhaust head tube which comprises a bent exhaust head tube body (1), wherein a nut installing hole (2) is formed in the bent exhaust head tube body (1), a nut pit (3) used for welding a nut is formed in the edge of the nut installing hole (2), and the nut pit (3) is planar. By adopting the exhaust head tube, the nut pit for welding the nut is formed in the edge of the nut installing hole, and the nut is welded in the nut pit, so that the nut is enabled to be installed in a proper position without inclining, the nut is conveniently connected with other parts, and thus the stability of products is improved.
Description
Technical field
The utility model relates to the automobile exhaust pipe field, is pipe before a kind of engine exhaust specifically.
Background technique
Exhaust front pipe is the part of automobile engine exhaust system assembly, is also the critical component of outlet pipe, and due to the limited space of automobile chassis, often there is certain bending in exhaust front pipe, thereby to obtain suitable installing space.Exhaust front pipe is spirally connected with miscellaneous part again simultaneously, is provided with aperture on exhaust front pipe, when being threaded, will on aperture, weld a nut.Because exhaust front pipe is round tubular, so around aperture not on a plane, so during welded nut, easily cause tilt nut, and needing certain scolder to realize being connected with the firm of nut by around aperture, making a plane, product performance are unstable.
The model utility content
The technical problems to be solved in the utility model is, a kind of welded nut of being convenient to is provided, and the exhaust front pipe that can firmly be connected with nut.
Technical solution of the present utility model is, a kind of exhaust front pipe of following structure is provided, comprise crooked exhaust front pipe body, described exhaust front pipe body is provided with the nut mounting hole, and the edge of described nut mounting hole is provided with the nut recess for welded nut.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model, because the edge of nut mounting hole is provided with the nut recess for welded nut, nut is welded at the nut recess, guarantee that nut can install in place, can run-off the straight, thereby be convenient to being connected between nut and miscellaneous part, improved the stability of product.
As improvement, described nut recess is plane; Be the nut mounting hole around be plane, further improve the planarization that nut is installed.
The accompanying drawing explanation
The structural representation that Fig. 1 is exhaust front pipe of the present utility model.
As shown in the figure 1, the exhaust front pipe body, 2, the nut mounting hole, 3, the nut recess.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, exhaust front pipe of the present utility model, comprise crooked exhaust front pipe body 1, and described exhaust front pipe body 1 is provided with nut mounting hole 2, and the edge of described nut mounting hole 2 is provided with the nut recess 3 for welded nut.
Described nut recess 3 is plane; But be not limited to this shape, except adopt plane, can also be arranged to the annular groove shape.
Below only with regard to the utility model preferred embodiment, be described, but can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment, and its concrete structure allows to change.In a word, all various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
Claims (2)
1. an exhaust front pipe, comprise crooked exhaust front pipe body (1), described exhaust front pipe body (1) is provided with nut mounting hole (2), it is characterized in that: the edge of described nut mounting hole (2) is provided with the nut recess (3) for welded nut.
2. exhaust front pipe according to claim 1, it is characterized in that: described nut recess (3) is plane.
