Abstract

The invention relates to a device for hanging an automotive muffler. The device for hanging the automotive muffler comprises a hook and a rubber hanging portion, wherein one end of the hook penetrates through one of installing holes of the rubber hanging portion, and the hook is connected with the rubber hanging portion, and is attached to the side face of the rubber hanging portion to carry out locating through an upset head arranged on the end portion of the hook. According to the improvement, a clamping groove which is arranged in the length direction of a hook rod is formed in the hook, a buckle is installed in the clamping groove, and the buckle is attached to the other side face of the rubber hanging portion through a limiting face, facing the rubber hanging portion, of the buckle, and limits the rubber hanging portion. According to the device for hanging the automotive muffler, the position of the buckle can be rapidly adjusted at any time, the assembling state of the rubber hanging portion can be adjusted, the problem that abnormal sounds, breakage, abrasion deformation, axial movement and the like of the rubber hanging portion happen is effectively solved, and the frequency of after-sales repair and the after-sales three-guarantee cost are effectively reduced.

Description

A kind of automotive muffler erecting by overhang

Technical field

The present invention relates to automotive muffler assembly structure.

Background technique

At present, automotive muffler generally adopts hook and rubber to hang the mode of assembling.The general common iron that adopts of hook, is squeezed into heading by its one end, hangs and is linked and packed with rubber.Although this structure technique is simple, after assembling, there is following problem: rubber is hung attitude and cannot be adjusted; Rubber is hung and is had torsional deformation; Cannot limit the axial jump that rubber is hung, lockup capacity is poor.The problems referred to above can cause abnormal sound that rubber hangs, fracture, abrasion deformation etc., and serious situation can be damaged to silencing apparatus, even needs to change muffler assembly, and the three guarantees maintenance cost after sale of producer is improved.

Summary of the invention

The present invention disclose a kind of easy for installation, location fast, have and regulate and the automotive muffler hook structure of lockup capacity, to solve rubber, hang due to problems such as abnormal sound that assembling condition brings, fracture, abrasion deformation, axial jumps, and can effectively improve formation efficiency.

Technological scheme of the present invention is as follows:

An automotive muffler erecting by overhang, comprises that hook and rubber hangs, the mounting hole that hang through rubber described hook one end, and connection rubber is hung, and location is close in the side of hanging by heading and the rubber of end; Its improvement is, on hook, have along the draw-in groove of hook pole length direction, buckle is installed in draw-in groove, the confined planes that buckle is hung towards rubber by it is close to the another side that rubber is hung, rubber is hung spacing, can conveniently adjust rubber like this and hang rigging position, and prevent by buckle the axial float that rubber is hung, prevent abnormal sound.

Further, described buckle is flexible component, for several fonts, top is dop, puts in draw-in groove, and its horizontal width is greater than the width of draw-in groove, the left and right of several fonts is two symmetrical card arms, they draw in to centre symmetrically at middle part, and bottom separates to both sides respectively, and middle part furlling part relies on elasticity and draw-in groove to realize clamping.Adopt flexible buckle, simple in structure, be easy to install.

Further, at least one card of described buckle is provided with described confined planes on arm, and confined planes is the plane forming in the turnover of card arm upper side, is tight against the side of hanging at rubber by this confined planes, reach rubber is hung spacing.

Be more preferably on the card arm of left and right such confined planes is all set, two confined planes are parallel relatively, and no matter buckle from which direction assembles like this, can reach the position-limiting action of all rubber being hung, and can not occur misloading, easy to assembly.

Further more preferably, at least one card of buckle, retainer is set on arm, relative position when two card arms of retainer restriction close up, can be used for control card to be buckled in amount of deformation when stressed, protection buckle.

Better, retainer is the folding portion to another card arm direction forming on card arm, and such structural design is fairly simple, is easy to make.

Further better, retainer all arranges on two card arms, can reach and be subject to equilibrium of forces like this.

More preferably, the outer side surface of described retainer has just formed described confined planes, and such parts have just played various effects, make the more reasonable structure of buckle, simpler.

Adopt above-mentioned suspender structure, can adjust at any time, rapidly snapped-in position, the assembling condition that regulates rubber to hang, effectively solves the problems such as abnormal sound that rubber hangs, fracture, abrasion deformation, axial jump, effectively reduces after-sales service efficiency and three guarantees cost after sale.

Embodiment

Below in conjunction with accompanying drawing, further illustrate the present invention:

As shown in Figure 2, automotive muffler with erecting by overhang by rubber hang 2, link up with 3 and buckle 4 form, rubber is hung 2 and is assemblied in hook one end of 3, a side is spacing by the heading of linking up with end, opposite side is spacing by buckle 4.

Embodiment as shown in Figure 5, squeezes out frustoconic shape heading 3-1 in one end of hook 3, hangs side simultaneously and forms heading locating face 3-2, and stamp out along its length draw-in groove 3-3 at the cylindrical section 3-4 of hook 3 on heading near rubber.

In a specific embodiment as shown in Figure 6, Figure 7, buckle 4 is to adopt spring steel to be made, and is symplex structure, otherwise without just dividing, prevents misloading.It is specially several fonts, top is dop 4-1, put in draw-in groove, its horizontal width is greater than the width of draw-in groove, and the left and right of several fonts is two symmetrical card arm 4-2, and they draw in to centre symmetrically at middle part, bottom separates to both sides respectively, middle part furlling part forms groove, relies on elasticity and draw-in groove to realize clamping, and buckle is fixed up.On two card arm 4-2, there are two symmetrical folding portions, the retainer 4-4 of distance when formation restriction two card arms close up mutually, retainer is distortion confined planes towards the position of card arm, distortion confined planes is used for control card and is buckled in amount of deformation when stressed, the outer side surface of retainer 4-4 is simultaneously again as confined planes 4-3, for the location of buckle, prevent from that rubber from hanging to jump.

Embodiment as shown in Fig. 3, Fig. 8 and Fig. 9, during assembling, hook 3 is hung in the mounting hole 5-1 2 and passed from rubber, adjust the position that rubber is hung, rubber is hung in vertical state naturally, made rubber hang on 2 rubber and hang the first confined planes 5-1 and be close to heading confined planes 3-2.With instrument, buckle 4 is clamped, distortion confined planes by retainer prevents excessive breaking-up of buckle 4 amount of deformation, buckle 4 is put into draw-in groove 3-3 on hook 3, mobile buckle 4, adjust snapped-in position, make confined planes 4-3 and rubber hang rubber on 2 and hang the second confined planes 5-3 and be close to, unclamp buckle 4, it is upper that buckle dependence self elastic force is clamped on hook, completes assembling.After assembling, effect as shown in Figure 2 and Figure 4.

Finally, by arc section 3-5 and the silencing apparatus 1 of linking up with on 3, weld, complete whole erection welding process, as shown in Figure 1.

Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of the claims in the present invention and equivalent technologies thereof, the intent of the present invention also comprises these changes and is out of shape interior.
