Description

Novel screw

Technical Field

The utility model relates to a screw, in particular to novel screw.

Background

Screws are commonly used in machinery, electrical appliances, buildings, etc., and are generally made of metal or plastic, and are cylindrical, and grooves with concave and convex surfaces engraved thereon are called threads. The primary function of the screw is to engage two objects or to fix the position of an object. The screws are typically removable or re-tightenable at will without loss of efficiency. The top diameter of general screw is great, and the common circular, square or regular hexagon that has, if the top is regular hexagon, can rotate the screw with the spanner, if the top is circular, the top openly also has the flute, facilitates the use corresponding screwdriver and rotates the screw. The most common grooves are in the shape of a straight line, cross, square, and other shapes. Some screws do not have a larger diameter head, such as a set screw, for example, so that the screw can be locked entirely into the workpiece without exposed portions.

The screw disclosed in patent No. CN201821798301.3 has good hardness and corrosion resistance, good installation stability, and is suitable for various loading and unloading tools

Although the above patent scheme solves the defects of the traditional screw, the scheme still has some defects 1, and the existing screw generally only has a thread groove with one width, so that the rotary clamping of the screw is not tight enough, and the use quality of the screw is seriously influenced; 2. the screw cap of the existing screw basically adopts a horizontal mode to cover the opening end of the screw hole, so that the screw is easy to loosen; to this end, we propose a new screw to solve the problems mentioned in the background above.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a block can be carried out between the nail body and the plate body to the pin fin, thereby the rethread plum blossom groove can use the screw along the rotatory nail body of thread groove A and thread groove B, thereby simultaneously owing to adopt the double thread groove of two kinds of different width can be with the nail body tight block in the plate internal portion after loose earlier, the cardboard through the faller cap lateral wall can be with the more stable block of faller cap at the plate body surface, the stable and reliable use quality of screw has been realized, be fit for being extensively promoted and used.

The utility model provides a specific technical scheme as follows:

the utility model provides a pair of novel screw, including the nail body, the pin fin has been seted up to nail body bottom surface outer wall, just nail body upper surface has linked up the fallboard, thread groove A has been seted up to nail body lateral wall, just thread groove B has been seted up to thread groove A top position, just the draw-in groove has been seted up to the fallboard lateral wall.

Optionally, the number of the thread grooves a and the number of the thread grooves B are multiple, and the pitch of the thread grooves B is smaller than that of the thread grooves a.

Optionally, the clamping plates are connected to the inner side wall of each clamping groove, and the number of the clamping grooves and the number of the clamping plates are four.

Optionally, a quincunx groove is formed in the upper surface of the nail cover, and the quincunx groove is located in the middle of the upper surface of the nail cover.

The utility model has the advantages as follows:

1. the utility model discloses a pin fin can carry out preliminary block between the nail body and the plate body, thereby the rethread plum blossom groove can use the screw along the rotatory nail body of thread groove A and thread groove B, thereby simultaneously owing to adopt the double thread groove of two kinds of different width can be with the nail body tight block in the plate internal portion after loose earlier, has avoided only having the thread groove of a width, has improved the compactness of the rotatory block of screw, has improved the practicality of screw.

2. The utility model discloses a cardboard of nail lid lateral wall can cover the more stable block of nail lid at the plate body surface, has avoided adopting the horizontally mode to cover the screw open end, has just also avoided taking place between nail lid and the plate body not hard up simultaneously, has realized that the screw is stable and reliable use quality.
