This condition may present two problems: a. the assembly blanking cover is uneven, the laminating degree is not good, the protection effect is influenced b, after the blanking cover is disassembled, the plastic opening plug can fall out from the blanking cover hole, and the hidden danger of falling into the supercharger exists everywhere when the plastic opening plug falls off. The inconvenience of detaching the plug cover has become a prominent problem when the supercharger is used.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a quick detachable anti-drop booster drill way blanking cover, this blanking cover can avoid the opening stifled drop.
In order to solve the technical problem, the utility model discloses a technical scheme be:
the utility model provides a quick detachable anti-drop booster drill way blanking cap, includes that blanking cap and opening are stifled, be equipped with the pilot hole of being connected with the opening is stifled on the blanking cap, the shape of pilot hole is oval, the opening stifled with the pilot hole joint.
The plug cover is provided with a dismounting ring, and the dismounting ring is fixed on one side of the assembling hole.
The plug cover is provided with a pulling piece, the pulling piece is arranged at the assembling hole, and the middle part of the pulling piece is connected with the plug cover through a connecting plate; one end of the pulling piece can block the opening.
The opening block is provided with a notch matched with the pulling piece.
The pulling-on piece adopts plastics material.
The opening plug is made of plastic materials.
Compared with the prior art, the utility model, the beneficial effect who has is:
the assembling hole of the blocking cover is improved from a common round hole to an elliptical hole. Because the elliptical hole has the effect of adjusting the pitch of the holes, the plastic opening elastic plug is matched for use, so that the fitting degree and the protection effect of the assembled plug cover are better. The assembly size of the elastic plug for the plastic opening is improved. The large-clearance assembly requirement of the original elastic plug and the plugging cover hole is improved to be the interference fit of the elastic plug and the plugging cover elliptical hole, and when the plugging cover is disassembled after assembly, the elastic plug and the plugging cover are disassembled together, and the plug is still assembled with the plugging cover and is not easy to fall off. Meanwhile, the plug cover is convenient to disassemble.

Detailed Description
The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in figures 1 and 2, the quick detachable anti-drop supercharger orifice blanking cover comprises a blanking cover 1 and an opening plug 2, wherein an assembly hole 3 connected with the opening plug 2 is formed in the blanking cover 1, the assembly hole 3 is oval, and the opening plug 2 is connected with the assembly hole 3 in a clamping mode.
When the blocking cover 1 is assembled on the supercharger, the opening blocks 2 are respectively arranged in the oval assembling holes 3 of the blocking cover 1 according to the required quantity, then the opening blocks 2 and the blocking cover 1 are assembled on the end surface of the orifice flange 8 of the supercharger part together, the blocking cover 1 is flatly attached to the end surface of the flange 8, the opening blocks 2 are respectively pressed, and the blocking cover 1 is made to be attached to the end surface of the orifice flange 8 of the part.
The opening plug 2 is clamped with the assembling hole 3, namely the opening plug and the assembling hole are in interference fit, the elastic plug and the plugging cover 1 can be detached together, and the opening plug and the plugging cover 1 are still assembled together and are not easy to fall off.
Further, as shown in fig. 3, a detaching ring 4 is provided on the closure 1, and the detaching ring 4 is fixed on one side of the assembling hole 3. When the plug is detached, a tool (a straight screwdriver) and the like can be utilized to penetrate through the detaching ring 4, one end of the tool presses the opening plug 2, and the other end of the tool is forced to tilt upwards, so that the opening plug 2 and the plug cover 1 can be tilted to be separated; and in the process of disassembly, the tool can block the opening plug 2 to prevent the opening plug from falling off.
Further, when the dismounting ring 4 is provided, it is also necessary to use a tool for dismounting, and therefore:
as shown in fig. 4, the plugging cover 1 is provided with a pulling piece 5, the pulling piece 5 is arranged at the assembly hole 3, and the middle part of the pulling piece 5 is connected with the plugging cover 1 through a connecting plate 6; one end of the pull tab 5 can block a part of the opening plug 2. When the opening plug 2 is installed, one end of the pull piece 5 is required to be tilted to be not shielded, and then the opening plug 2 is installed in the assembling hole 3; when the pull piece is detached, the other end of the pull piece 5 is pulled upwards, and the other end of the pull piece 5 can block the opening plug 2 to further prevent the opening plug from falling off.
Furthermore, the dismounting ring 4 needs to be tilted when the opening plug 2 is installed, and certain inconvenience is caused during installation; thus:
as shown in fig. 5, the opening block 2 is provided with a notch 7 which is matched with the pull piece 5. During installation, the notch 7 is aligned with the pull piece 5 and inserted into the assembly hole 3, and the opening plug 2 is rotated after the notch 7 is assembled, so that the notch 7 deviates to ensure that the pull piece 5 can block the opening plug 2.
Further, the pull piece 5 is made of plastic.
Further, the opening plug 2 is made of plastic.
The above description has been made in detail only for the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art, and all such changes are intended to be encompassed by the present invention.
