Abstract
The utility model relates to a device for connecting blast pipe, including a fixed outer lane, the equipartition has three pressure spring on the inside wall of fixed outer lane, pressure spring's tip is provided with the arc piece, the internal diameter of arc piece is less than or equal to the external diameter of blast pipe, three arc piece constitutes one jointly and compresses tightly the inner circle, pressure spring remains the trend that compresses tightly to the centre of a circle throughout, be provided with the mount that is L shape on the lateral wall of fixed outer lane. It is fixed with the blast pipe that this connecting piece passes through the pretightning force of spring, simultaneously because the spring has the extensibility for blast pipe and chassis can be flexible be connected.
Description
Technical field
The utility model relates to a kind of connection set of outlet pipe.
Background technique
Blast duct for vehicle is connected with motor, motor, in running, can produce larger vibration, and its outlet pipe is along with engine luggine, outlet pipe is connected with chassis do not allow to adopt rigid connection, need allows outlet pipe can displacement by a small margin in all directions.On existing market, the normal rubber sleeve that adopts connects, and again because exhaust gas temperature is very high, the easy expanded by heating of rubber sleeve softens, and restricted lifetime, reliability is lower.
Model utility content
The utility model makes improvement for above-mentioned prior art Problems existing, namely technical problem to be solved in the utility model is to provide a kind of connection set of outlet pipe, make the connection that outlet pipe and chassis can be flexible, can bear the worst hot case of outlet pipe, reliability is higher.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of connection set of outlet pipe, comprise a fixing outer ring, described fixing outer ring madial wall is evenly equipped with three holddown springs, the end of described holddown spring is provided with arc-like sheet, the internal diameter of described arc-like sheet is less than or equal to the external diameter of outlet pipe, described three arc-like sheets form a compression inner ring jointly, described holddown spring remains the trend compressed to the center of circle, and the outer side wall of described fixing outer ring is provided with L-shaped fixing frame.
Further, described fixing frame is provided with bolt hole.
Compared with prior art, the utility model has following beneficial effect: outlet pipe is fixed by the pretightening force of spring by this link, simultaneously because spring has extensibility, makes outlet pipe and chassis can the connection of flexibility.Outlet pipe is in vibration processes, and can have the moving displacement of certain amplitude in all directions, prevent exhaust pipe vibrations from wearing and tearing, this link is metal material simultaneously, and therefore can bear the worst hot case of outlet pipe, reliability is higher.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the working state schematic representation of the utility model embodiment.
In figure: 1-fixes outer ring, 2-holddown spring, 3-arc-like sheet, 4-fixing frame, 41-bolt hole, 5-outlet pipe.
Embodiment
Embodiment one: as shown in Figure 1 and 2, a kind of connection set of outlet pipe, comprise a fixing outer ring 1, described fixing outer ring 1 madial wall is evenly equipped with three holddown springs 2, the end of described holddown spring 2 is provided with arc-like sheet 3, and the internal diameter of described arc-like sheet 3 is less than or equal to the external diameter of outlet pipe 5, and described three arc-like sheets 3 jointly form one and compress inner ring, described holddown spring 2 remains the trend compressed to the center of circle, and the outer side wall of described fixing outer ring 1 is provided with L-shaped fixing frame 4.
In the present embodiment, described fixing frame 4 is provided with bolt hole 41.
Outlet pipe is fixed by the pretightening force of spring by this link, simultaneously because spring has extensibility, makes the connection that outlet pipe and chassis can be flexible, by outlet pipe compression, keeps certain pretightening force.Outlet pipe is in vibration processes, and can have the moving displacement of certain amplitude in all directions, prevent exhaust pipe vibrations from wearing and tearing, this link is metal material simultaneously, and therefore can bear the worst hot case of outlet pipe, reliability is higher.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
Claims (2)
1. the connection set of an outlet pipe, it is characterized in that: comprise a fixing outer ring, described fixing outer ring madial wall is evenly equipped with three holddown springs, the end of described holddown spring is provided with arc-like sheet, the internal diameter of described arc-like sheet is less than or equal to the external diameter of outlet pipe, described three arc-like sheets form a compression inner ring jointly, and described holddown spring remains the trend compressed to the center of circle, and the outer side wall of described fixing outer ring is provided with L-shaped fixing frame.
2. the connection set of outlet pipe according to claim 1, is characterized in that: described fixing frame is provided with bolt hole.
