Abstract
An automobile muffler with a clamping-locking mechanism comprises a sound elimination mechanism assembly and a clamping-locking mechanism, wherein the clamping-locking mechanism comprises bosses and grooves, the bosses are arranged on positions where a plurality of clapboards are respectively connected with air inlet core pipes, tuning core pipes and air outlet core pipes, and the grooves matched with the bosses are respectively arranged on pipe bodies of the air inlet core pipes, the tuning core pipes and the air outlet core pipes. When the automobile muffler with the clamping-locking mechanism cannot adopt a welding mode to connect with the sound elimination mechanism assembly (especially the clapboards are connected with the core pipes in a linkage mode) in a linkage mode, the clamping-locking mechanism is a relatively effective linkage mode, so that the whole sound elimination mechanism assembly is ensured to be large in stiffness, radiation noise is prevented from happening when an automobile exhaust system is used, durability of the automobile muffler is improved, and service life of the exhaust system is prolonged.
Description
Technical field
The utility model relates to the automobile exhaust system field, relates to the automotive muffler internal partition and connects with the core pipe, particularly a kind of automotive muffler that has locking mechanism.
Background technique
After inner each the parts assembling of silencing apparatus, each parts need connect firmly.Wherein, dividing plate and core pipe connect the general form that adopts welding.But welding also has some shortcomings: welding slag falls in the silencing apparatus cavity and can't remove, and produces abnormal sound; When muffler chamber is dark, receive spatial limitation, welding gun can't be accomplished welding action etc.
Therefore, produce in the product, need a kind of new-type locking mechanism, substitute dividing plate and core pipe and adopt welding manner to connect the problem that can't realize in reality.
The model utility content
The purpose of the utility model; Provide a kind of automotive muffler that has locking mechanism, the connecting mode of this new-type dividing plate and core pipe is after inner each the parts assembling of silencing apparatus is accomplished; Exert pressure from core pipe inside; With core pipe and the dividing plate section of cooperation, radially extrusion modling simultaneously utilizes certain deformation amount and specific shape to guarantee that the core pipe connects firmly with dividing plate.
The technological scheme that adopts is:
A kind of automotive muffler that has locking mechanism comprises noise elimination mechanism assembly and locking mechanism, and the noise elimination mechanism assembly comprises a plurality of dividing plates, air inlet core pipe, tuning core pipe and exhaust core pipe, is known technology;
Locking mechanism comprises boss and groove;
Boss be arranged on a plurality of dividing plates respectively with the joint of air inlet core pipe, tuning core pipe and exhaust core pipe, on the body of air inlet core pipe, tuning core pipe and exhaust core pipe, offer the groove that matches with boss respectively, boss is locked each other with groove and is cooperated.
The advantage of the utility model is:
The utility model can't adopt welding manner to connect silencer component when (particularly dividing plate connects with the core pipe); Locking mechanism is more effective connecting mode; Guarantee that whole silencer component has bigger rigidity; Prevent radiated noise to occur in the automobile exhaust system using process, improve durability, prolong vent systems working life.
Description of drawings:
Fig. 1 is the overall structure schematic representation after the utility model connects.
Fig. 2 is the enlarged diagram of the locking mechanism after the utility model connects.
Embodiment
A kind of automotive muffler that has locking mechanism comprises noise elimination mechanism assembly and locking mechanism 1, and the noise elimination mechanism assembly comprises a plurality of dividing plate 6, air inlet core pipe 4, tuning core pipe 5 and exhaust core pipe 7, is known technology;
Boss 2 be arranged on a plurality of dividing plates 6 respectively with the joint of air inlet core pipe 4, tuning core pipe 5 and exhaust core pipe 7, on the body of air inlet core pipe 4, tuning core pipe 5 and exhaust core pipe 7, offer the groove 3 that matches with boss 2 respectively.
