Description

External automobile tail covering protection device Technical Field The utility model belongs to the technical field of automobile protection, and particularly relates to an external automobile tail covering protection device. Background It can be when the vehicle encounters collision, scraping, act as the buffer layer, alleviate the impaired degree of car tail covering, cause wearing and tearing to car lacquer when preventing loading and unloading goods, extension covering life, at the decorative level, abundant style and color can satisfy car owner's many aesthetic, promote the vehicle identification degree, in addition, can also cover the afterbody flaw temporarily, it is whole pleasing to the eye to keep the vehicle, be that car owner guard loves the ability of car select current external car afterbody to cover protection device, when the installation, fixed through the mode of pasting, need fixed firm avoiding droing when the collision, pasted viscosity is very high, lead to being difficult to dismantle after the change, consequently, propose external car afterbody to cover protection device. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the external automobile tail covering protection device, and the adhesive layer can lose viscosity by injecting the sol into the valve body, so that the buffer pad can be easily detached, and the problems that the buffer pad is fixed in an adhesive mode in the prior art, needs to be fixed firmly to avoid falling off in collision, and is difficult to detach after replacement are solved. The external automobile tail covering protection device comprises a buffer pad, wherein an installation groove is formed in the inner side of the buffer pad, a retainer is fixed on the inner side of the installation groove, a cavity is formed in the retainer, a plurality of first through grooves are formed in one side, far away from the buffer pad, of the retainer, an adhesive layer is further fixed on one side, far away from the buffer pad, of the retainer, a plurality of second through grooves are formed in the outer side of the adhesive layer, two valve bodies are embedded in the buffer pad, each valve body comprises two small cylinders and one large cylinder, first through grooves are formed in the two small cylinders, second through grooves are formed in the large cylinders, a diaphragm is fixed on the inner side of the second through grooves, and the buffer pad comprises a buffer layer, a waterproof layer and a tearing-resistant layer. As a preferable embodiment of the present utility model, the interior of the first through groove is communicated with the interior of the cavity. As a preferable embodiment of the present utility model, the depth of the mounting groove is equal to the sum of the thicknesses of the adhesive layer and the holder. As a preferable embodiment of the present utility model, the positions of the plurality of second through grooves correspond to the positions of the plurality of first through grooves, respectively.
