However, the soundproof blocks in the vehicle body structure are placed in the metal plate cavity of the vehicle body to rotate and cannot be completely fixed, so that the metal plate cavity channel can generate and transmit vibration noise, and the technical problem is not well solved.

Chinese patent ZL201220690883.X discloses a cavity sound insulation block arranged on the inner side of the lower part of an A column of a car, which comprises a high-temperature-resistant bracket and an expansion body material which is connected to the bracket and can be foamed and expanded after being heated; the bracket has a shape similar to the section of the car body cavity at the lower part of the A column of the car, a gap is reserved between the bracket and the peripheral car body plate with the corresponding section, and two elastic buckles used for being respectively clamped into two round holes of the car body plate are arranged at one side of the bracket; the elastic buckle is characterized in that a stop block for preventing the buckle from being excessively clamped is arranged at the lower part of the elastic buckle, and the elastic buckle and the stop block are connected into a whole. The sound insulating block of this patent can prevent through setting up the end piece that the part is excessive to be gone into, but it still can't solve the sound insulating block and easily takes place rotatory problem in the cavity, in addition, during the installation, owing to lack the location, the elastic buckle produces the damage because of mistake touch car body panel beating cavity other positions very easily.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a loss prevention rotation-proof automobile body panel beating cavity sound-insulating block in order to overcome the defects of sound-insulating block easy rotation, elastic buckle easy damage and the like existing in the prior art.

The purpose of the utility model can be realized through the following technical scheme:

the utility model provides a loss prevention prevents that rotation automobile body panel beating cavity sound-proof block, includes the support frame, sets up expandable inflation body material in support frame peripheral position and heating back to and set up in a side of support frame and be used for the elasticity buckle be connected with automobile body panel beating cavity, the support frame still is equipped with the reference column round pin and ends the position round pin at the other elasticity buckle, and wherein, the reference column round pin is used for the contact to survey automobile body panel beating cavity profile in order to fix a position elasticity buckle mounted position, ends the position round pin be used for with the automobile body panel beating cavity on end the position hole cooperation for sound-proof block and automobile body panel beating cavity are.

Further, three positioning pins are installed.

Furthermore, the height of the positioning pin is higher than that of the elastic buckle.

Furthermore, zero clearance fit is formed between the stop pin and the stop hole.

Furthermore, the stop pins are provided with at least two stop pins, and the height of each stop pin is lower than that of the elastic buckle.

Furthermore, the elastic buckles are provided with a plurality of elastic buckles, and different elastic buckles are connected through reinforcing ribs arranged on the side faces of the support frame.

Compared with the prior art, the utility model discloses utilize location pin, elasticity buckle and end a round pin isotructure to realize the composite location installation, wherein, go into the automobile body sheet metal component through elasticity buckle card and realize fixing, fix a position in advance through the location pin to avoid bumping and damaging between elasticity buckle and the automobile body part, effectively prevent the acoustic celotex piece because of rotating and make the part inefficacy through ending the round pin, and then the many-sided sealed automobile body sheet metal cavity that can be better after the expansion body material foaming inflation of acoustic celotex piece part of having guaranteed.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the structure of the present invention;

the notation in the figure is:

1-support frame, 2-expansion body material, 3-elastic buckle, 4-reinforcing rib, 5-stop pin and 6-positioning pin.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

In the following examples, the support frame used may be a nylon support frame, and the material of the expansion body used may be a product that is commercially available in the art, specifically, a rubber or plastic filling material (HT1124M-8A) available from tiagan plastic products ltd, vitta, or other conventional commercially available materials having the same property of being expandable after heating.

Example 1

The utility model provides a car body panel beating cavity sound insulating block is prevented rotating by loss, its structure is seen in figure 1 and figure 2, including support frame 1, set up at support frame 1 peripheral position and expandable inflation body material 2 after heating to and set up at one side of support frame 1 and be used for the elasticity buckle 3 of being connected with car body panel beating cavity, support frame 1 possess with the inboard plane shape of panel beating cavity cross-section looks adaptation in car A post lower part.
