Novel screw blanking cover
Technical field
The utility model relates to a kind of automotive parts, particularly relates to a kind of novel screw blanking cover.
Background technology
The screw blanking cover adopts car coat type at present, install easily, but because screw blanking cover and handle assembly tolerance clearance are 0.5mm, very difficult during dismounting, must use pocket knife or other thin and have the instrument of intensity to put in the gap of cooperation blanking cover to be disassembled, very easily cause body surface to be scratched.
Patent Office of the People's Republic of China disclosed the utility model that a kind of name is called a kind of special-purpose blanking cover structure on May 26th, 2010, and its Granted publication number is CN 201484315U.This utility model discloses a kind of special-purpose blanking cover structure, comprise blanking cover and nut, described blanking cover is that the tube that offers open slot emits shape, described nut places the tube of blanking cover to emit, the appearance top of described nut be gengon, bottom for spherical, in the tube cap of described blanking cover also the bottom sphere of adaptive nut be provided with spherical groove.This utility model is simple in structure, good looking appearance, cost are low, and its weak point is, and is relatively more difficult during dismounting because it is that specialized nut and blanking cover are used, and need turn with socket wrench, easily body surface caused scuffing.
Summary of the invention
The purpose of this utility model is to solve screw blanking cover dismounting difficulty in the prior art, easily body surface is caused the deficiency of scuffing during dismounting, and a kind of easy dismounting is provided, and can not cause the novel screw blanking cover of scuffing during dismounting to body surface.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of screw blanking cover, comprise the blanking cover body, described blanking cover body one end is provided with fin, and described fin is provided with the straight muscle of striped, described blanking cover body one end also is provided with dop one, and the other end is provided with rubber-like dop two.The utility model has increased fin at an end of blanking cover body, the fin outside face has increased the straight muscle of striated, increasing friction force, is provided with rubber-like dop two at the other end of blanking cover body, this dop curves inwardly, when needs knockout screw blanking cover, push away fin with finger, utilize the friction force of the straight muscle of striped on finger and the fin, make dop two produce elastic force, blanking cover is upspring, and dismounting more can not produce scuffing to body surface easily.
As preferably, described blanking cover body bottom is provided with boss, described boss and this body by integral forming of blanking cover.When the screw blanking cover was installed on the object, boss placed object, and the blanking cover outside face carries out the secondary shutoff to the gap of boss and object, has guaranteed good sealing property.
As preferably, it is half-cylindrical that described fin is.When finger pushed away fin, semi-cylindrical fin made that finger is more comfortable, and semi-cylindrical fin when cooperating with the blanking cover body transition more even, make screw blanking cover profile more attractive in appearance.
As preferably, described dop two is provided with two-sided grab.Guarantee when dop two snaps in object more firm.
As preferably, described dop one is L-shaped.Snap in object easily, make the loading and unloading of screw blanking cover more convenient.
The beneficial effects of the utility model are: easy to loading and unloading, good airproof performance, simple in structure, and with low cost.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure:
1. blanking cover body, 2. dop two, 3. two-sided grab, 4. fin, the 5. straight muscle of striped, 6. dop one, 7. boss.
The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings 1, the technical solution of the utility model is described in further detail.
A kind of novel screw blanking cover (as shown in Figure 1), comprise blanking cover body 1, described blanking cover body 1 is a cuboid, blanking cover body 1 bottom has and blanking cover body 1 integrated boss 7, boss 7 is stepped appearance with blanking cover body 1, described blanking cover body 1 one ends have bar fin 4, it is half-cylindrical that described fin 4 is, described fin 4 is one-body molded with blanking cover body 1, be carved with the straight muscle 5 of striped on the described fin 4, described blanking cover body 1 has an end Connection Card of fin 4 first 6, and the other end connects rubber-like dop 22, described dop 1 is L-shaped, and described dop 22 connects two-sided grab 3.When the screw blanking cover snaps in object, push away fin 4 with finger, utilize straight muscle 5 of striped and the friction force that finger produces on the fin 4, with dop 22 bending compressions, make dop 1 snap in object, the screw blanking cover promptly tightens with object; When needs knockout screw blanking cover, only need to push away fin 4 with being meant, the friction force that utilizes the straight muscle 5 of striped on the fin 4 and point is with dop 22 bending compressions, make dop 1 break away from from object, utilize the elastic force of dop 22, the screw blanking cover can be ejected, dismounting can not cause scuffing to body surface easily.
Above-described embodiment is a kind of preferable scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
