Abstract
The utility model discloses a special blocking cover structure. The structure comprises a blocking cover and nuts, wherein the blocking cover adopts a cylinder cap shape formed with an open slot, the nuts are arranged in the cylinder cap of the blocking cover, and barb type grooves are formed at the top part of the blocking cover, so as to be convenient for a user to take with fingers. Because the structure is coordinately used by combining the special nuts and the multifunctional blocking cover, and the special nuts are provided with polygons, screwing with a socket spanner to disassemble repeatedly is convenient; a spherical structure arranged at the lower end is used to guide a ball head; spherical grooves are formed at the lower sphere of the nuts matched with the cylinder cap of the multifunctional blocking cover; and when the multifunctional blocking cover is deformed in an elastic way and in assembled match with the ball head structure of the special nut, the original state is automatically restored, thereby having good sealing property. The structure has the characteristics of beauty appearance, low cost, convenient operation, and easy manufacture.
Description
Technical field
The utility model relates to a kind of blanking cover structure, especially relates to the special-purpose blanking cover structure in a kind of automotive trim field.
Background technology
In the automotive trim industry, blanking cover always is very general product.Its structure of general blanking cover all is a peripheral openings, the claw that rotates is installed locking.The patent No. is that the Chinese patent of CN01104264.8 discloses a kind of self-locking closure that is used for metallic sheet up-opening, have one and comprise a circle and be suitable for obtaining being close to shirt rim on the face of opening, and several are installed on the outer seal ring and when self-locking closure is in locked position rotationally, are suitable for obtaining being close to the claw on the reverse side of opening.Claw also is fixed on the protruding wing, and the protruding wing then is installed on the pushing and pressing part rotationally, and pushing and pressing part is suitable for rotating between the unlocked position of self-locking closure and locked position.Its weak point is though embody the function of blanking cover to a certain extent, to be nowhere near; Self function is very few, is not suitable for dismantling repeatedly, and using in the industry has certain limitation.
The utility model content
The purpose of this utility model provides a kind of special-purpose blanking cover structure, solves that present blanking cover sealing structure is bad, function singleness, is difficult for the problem of dismounting repeatedly.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of special-purpose blanking cover structure, comprise blanking cover and nut, and described blanking cover is the tube hat that offers open slot, described nut places the tube cap of blanking cover; It is characterized in that: described nut appearance top is that gengon, bottom are for spherical; Described blanking cover the tube cap in also the bottom sphere of adaptive nut spherical groove is set.
Further, specially the fluking type groove is set, is user-friendly to finger and takes at the blanking cover top.
Good effect of the present utility model: because it is to be used by specialized nut and multi-functional blanking cover together, and specialized nut is provided with gengon (as equilateral hexagon), conveniently turns dismounting repeatedly with socket wrench; The lower end is provided with globosity, cooperates as pilot seal; Multi-functional blanking cover mainly is to utilize elastic properties of materials distortion, in the tube cap also the bottom sphere of adaptive nut spherical groove is set.When multi-functional blanking cover generation elastic deformation with after the specialized nut ball head structure cooperates, will recover virgin state, good seal performance automatically.Consider and take, also specially the fluking type groove is set, be user-friendly to finger and take at the blanking cover top.Have simple structure, specious, cost is low, is convenient to operation, the characteristics that are easy to make.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.

Fig. 2 is a blanking cover schematic perspective view in the utility model.
Fig. 3 is a nut schematic perspective view in the utility model.
The specific embodiment
Consider convenient disassembly, describedly fluking type groove 12 is set at blanking cover 1 top.Described groove is two of symmetric arrangement.Make things convenient for the user to take at any time, free and relaxed.
Described nut 2 appearance top gengons 22 are equilateral hexagon.
During use, 3 times bolt is arranged, with specialized nut 2 and bolted, smoothly more special-purpose blanking cover 1 is assembled to specialized nut 2 with socket wrench specially adapted for it at sheet metal (dividing plate).At this moment, expansion cooperated with the sphere 21 of specialized nut 2 when elastic deformation took place 1 cap material spherical groove of special-purpose blanking cover 13, and the material spherical groove will recover virgin state automatically in the special-purpose blanking cover in back of working good, and assembling need not just can easily be in place by aligning direction.
