The utility model has reasonable structure and can effectively prevent corrosion.
Description
Technical Field
The utility model relates to the technical field of fasteners, in particular to a fastener convenient and fast to screw.
Background
At present, a bolt is arranged on the market and comprises a bolt head and a screw rod, a flange plate is arranged at the contact part of the bolt head and the screw rod, the bolt head, the screw rod and the flange plate are integrated, and when the bolt is installed and used, the flange plate is directly contacted with a part, so that the flange plate is easily abraded after long-term use, the service life is short, the maintenance cost is increased, and in the using process, because the structure of an operation part is single, some screw drivers in the market can only use a straight screw driver or a cross screw driver, and therefore the bolt is inconvenient to use.
Although chinese patent application No. CN209053912U discloses a bolt fastener, it should be noted that the mounting opening of such a fastener is exposed to corrosion, which has long been so that the mounting efficiency and the use of the bolt are seriously affected, and the inventor has proposed further improvement.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a fastener which is reasonable in structure, can effectively prevent corrosion and can be conveniently and quickly screwed.
In order to realize the purpose of the utility model, the utility model discloses a fastener which is convenient and fast to screw, and adopts the following technical scheme:
a fastener for facilitating quick-tightening, comprising:
a bolt head;
a screw located at one side of the bolt head; and
the screwing assembly is formed on the bolt head and comprises a plurality of grooves which are circumferentially arranged, the grooves are inwards shrunk from the bottoms of the grooves to the openings of the grooves, and elastic soft covers matched with the grooves are arranged in the grooves.
The utility model further provides a further improvement of the fastener which is convenient and fast to screw.
The utility model further provides a fastener convenient and fast to screw.
The fastener convenient and fast to screw is further improved in that the outer wall of the screw is also provided with a clamping groove.
The utility model further improves a fastener convenient and fast to screw.
Compared with the prior art, the utility model has the beneficial effects that:
1. through setting up the soft lid of elasticity, after the mounting transportation or fastening, set up soft lid and shield the recess, can effectively avoid the corrosion of soft lid.
2. Two adjacent grooves have different inner diameters and can be adapted to fastening devices with different sizes.
Drawings
FIG. 1 is a schematic diagram of the present invention.
Wherein, 1 bolt head, 2 screw rods, 3 grooves, 4 soft covers and 5 clamping grooves.
Detailed Description
The present invention is further illustrated by the following detailed description, which is to be construed as merely illustrative and not limitative of the remainder of the disclosure, and modifications and variations such as those ordinarily skilled in the art are intended to be included within the scope of the present invention as defined in the appended claims.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In the description of the present invention, it should be noted that the terms "vertical", "peripheral surface" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings or orientations or positional relationships that are conventionally placed when the products of the present invention are used, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or the element to which the description refers must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
Furthermore, the term "vertical" or the like does not imply that the components are required to be absolutely horizontal or overhanging, but rather may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, a fastener for facilitating quick-tightening, comprising:
a bolt head 1;
a screw 2 located on one side of the bolt head 1; and
the screwing assembly is formed on the bolt head 1 and comprises a plurality of circumferentially arranged grooves 3, the grooves 3 are inwards shrunk from the bottoms of the grooves to the openings of the grooves, and elastic soft covers 4 matched with the grooves are arranged in the grooves 3.
Specifically, the bolt head 1 is a hexagonal bolt head.
Specifically, the inner diameters of two adjacent grooves 3 are different.
Specifically, the outer wall of the screw is also provided with a clamping groove 5.
A pair of groove wall surfaces of the clamping groove are inclined surfaces, and the inclined directions of the groove wall surfaces incline outwards towards the directions of the threads on the two sides.
The specific working process and principle of the utility model are as follows: by arranging the elastic soft cover, the soft cover is arranged to shield the groove after the fixing piece is transported or fastened, so that the soft cover can be effectively prevented from being corroded; two adjacent grooves have different inner diameters and can be adapted to fastening devices with different sizes.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in the claims of the present invention should be covered by the present invention.
