In addition, adopt spline connection's structure between first cushion and the fastener for first cushion circumference location on the fastener guarantees that first cushion does not take place to rotate, and the axial displacement of fastener can only be followed to first cushion is favorable to the installation ear to take place deformation in arc wall department, and takes place the deformation back when the installation ear, and the lower terminal surface of first cushion supports the outer peripheral face that leans on at the blast pipe, remedies the not atress condition of breach department blast pipe outer peripheral face, further improves the location effect of blast pipe.
Drawings
Fig. 1 is a schematic structural diagram of a pipe hoop according to a first embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and a preferred embodiment.
Referring to fig. 1, the hoop for mounting the automobile turbocharging exhaust pipe comprises a fastener 11, a first cushion block 3, a second cushion block 6, a locking nut 4 and a hoop body 2.
The hoop body 2 is annular, the upper end of the hoop body is provided with a notch, and two sides of the notch are provided with mounting lugs with double-layer structures. The two ends of the hoop body vertically extend upwards for a certain length to form a first mounting lug 21, then the hoop body bends towards the outer side of the first mounting lug 21 and turns back to extend downwards to the root of the first mounting lug 21 to form a reinforcing lug 22, and the reinforcing lug 22 and the first mounting lug 21 form a double-layer structure. The reinforcing ears 22 are curved at portions thereof adjacent the root portions of the first mounting ears. The reinforcement lugs 22 are arranged to enable the mounting lugs of the hoop body 2 to have double layers, and the structural strength of the mounting lugs is improved.
The hoop body 2 and the mounting ears may be integrally formed, and may be formed by bending flat steel with a certain width and thickness, for example. The first mounting lugs 21 and the reinforcing lugs 22 are provided with through holes penetrating through the thickness direction thereof.
Fastener 11 includes hemisphere head and cylindric afterbody, and the afterbody is equipped with the external screw thread, and the columniform middle part is equipped with the spline. The hemispherical head design prevents excessive deformation of the reinforcement ears 22 due to localized overstressing of the reinforcement ears 22 when the reinforcement ears 22 are placed against the fastener head.
The first cushion block 3 is of a symmetrical structure, two opposite side faces are inwards sunken arc-shaped faces, and the bottom face is a pipeline supporting face. Run through two arcwall faces and be equipped with fastener installation through-hole, be equipped with the keyway in the installation through-hole, keyway and spline adaptation.
The second pad 6 is hemispherical and has a flat bottom surface, and a through hole is formed in the center of the hemisphere.
The locking nut 4 is a standard part and is commercially available.
When the hoop is used, the hoop body 2 is firstly sleeved on the exhaust pipe, the first cushion block 3 is arranged between the two mounting lugs, the bottom surface of the first cushion block 3 abuts against the upper end of the exhaust pipe, and the two arc-shaped surfaces face the first mounting lugs 21 of the two mounting lugs respectively; then, the tail part of the fastener 11 penetrates through the two mounting lugs and the first cushion block 3, and the first cushion block 3 and the fastener 11 are limited through a spline; and then the tail end of the fastener 11 is sleeved with a second gasket 6, the spherical surface of the second gasket faces the outer side surface of the reinforcing lug 22, and finally the locking nut 4 is screwed in. And the locking nut 4 is screwed to enable the two mounting lugs to be close to each other until the two first mounting lugs 21 are abutted against the inner wall of the arc-shaped groove of the first cushion block 3, so that the exhaust pipe is held tightly.
In this embodiment, one side surface of the second cushion block 6 facing the reinforcement ear is an arc surface 61 abutting against the reinforcement ear, and the design of the arc surface 61 can avoid the reinforcement ear 22 from being excessively stressed locally to cause transitional deformation. The first cushion block 3 is connected with the fastener 11 through a spline, and the side face of the first cushion block 3 opposite to the mounting lug is provided with an arc-shaped groove.
Adopt splined connection between first cushion 3 and the fastener 11 for first cushion circumference location on the fastener guarantees that first cushion can only follow fastener axial displacement, does not take place to rotate, is favorable to the installation ear to take place deformation in the arc wall department of first cushion, and takes place the deformation back when the installation ear, and the lower terminal surface of first cushion supports the outer peripheral face that leans on at the blast pipe, remedies the not atress condition of breach department blast pipe outer peripheral face, further improves the location effect of blast pipe.
In the present embodiment, a rubber pad 5 is provided between the reinforcing ear 22 and the mounting ear 21. Through the packing rubber pad in the space between strengthening ear and the installation ear, the rubber pad plays the effect of buffering and has certain elasticity, and increase lock nut's atress also avoids strengthening the transition deformation of ear and installation ear simultaneously.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
