Abstract
The utility model discloses a blast pipe bolt, including the bolt head with compress tightly the step, the bolt head with compress tightly and keep away from each other between the step and link to each other through the polished rod, the bottom that compresses tightly the step is connected with the screw rod, its characterized in that: the bolt head is a cylinder with a square at the top, the outer circle of the cylinder is provided with an external thread, and the external thread is screwed with the screw thread of the gland nut. The utility model discloses can better guarantee to connect the reliability to effectively compress tightly the mounting hole port at blast pipe interface pad position, avoid faults such as blast pipe gas leakage to produce.
Description
Technical Field
The utility model relates to a blast pipe bolt for vehicle vent-pipe connects.
Background
Under the operating condition of the automobile exhaust pipe, due to the influence of heat and exhaust pressure, the bolt loosening or the exhaust pipe sealing gasket is washed away frequently, so that the faults such as air leakage of the exhaust pipe and the like are caused.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a connection reliability can be better guaranteed is provided to effectively compress tightly the mounting hole port at blast pipe interface pad position, avoid the blast pipe bolt that faults such as blast pipe gas leakage produced.
Therefore, the utility model discloses an adopt following scheme to realize:
blast pipe bolt, including the bolt head with compress tightly the step, the bolt head with compress tightly and keep away from each other between the step and link to each other through the polished rod, compress tightly the bottom and the screw rod of step and be connected its characterized in that: the bolt head is a cylinder with a square at the top, the outer circle of the cylinder is provided with an external thread, and the external thread is screwed with the screw thread of the gland nut.
Above-mentioned technical scheme's blast pipe bolt, when the installation, compress tightly the step and play at first the inboard fastening that compresses tightly of blast pipe interface pad position mounting hole, then screw up gland nut again, make gland nut effectively compress tightly the mounting hole port at blast pipe interface pad position, not only play nut and tight effect, better guarantee the connection reliability, the effectual compressing tightly can prevent that blast pipe seal gasket from being washed away, avoid faults such as blast pipe gas leakage to produce.
Preferably, the bolt head, the polished rod, the pressing step and the screw rod are of an integrated structure formed by cold heading.
Drawings
The utility model discloses there is following figure:
figure 1 is a schematic structural view of the utility model,
fig. 2 is a top view in the direction of fig. 1.
Detailed Description
As shown in the figure, the utility model discloses an exhaust pipe bolt, including bolt head 2 and compression step 5, bolt head 2 with compress tightly and keep away from each other between the step 5 and link to each other through polished rod 4, the bottom that compresses tightly step 5 is connected with screw rod 6, bolt head 2, polished rod 4, compress tightly step 5 and screw rod 6 and be the fashioned body structure of cold-heading, bolt head 2 is the cylinder of top area square 1, square 1's effect makes things convenient for the wrench tool to move to exhaust pipe bolt's the twisting, the excircle of cylinder is equipped with the external screw thread, the external screw thread connects with gland nut 3 screw threads soon, gland nut 3's excircle is equipped with tool hole 7, in order to make things convenient for the tool to move gland nut 3.
