Description

Screw structure

The present invention provides a structure of a screw, especially a structure of a screw which is simple in structure, convenient in operation, reusable, and can be easily disassembled by hand.

Press, the screw is a common fastener that is widely used in machinery, electrical appliances and buildings. Generally, the material is metal or plastic, and the groove is engraved with a groove on the surface. The thread is a helically inclined surface that surrounds the side of the screw, allowing the screw to lock the screw cap or other object with a screw mechanism. Generally, the top diameter of the screw is large. Commonly, there are round, square or regular hexagons. If the top is a regular hexagon, you can use a wrench to turn the screw. If the top is round, the top of the top will also have grooves, which is convenient for use. Screwdriver turns the screw. Such screws generally require the use of tools, such as screwdrivers, wrenches, electric drills, etc., in order to actually complete the fastening or disassembly action. However, such tools are not readily available, so in order to obtain tools, it is necessary to waste some time, and these Tools have a certain weight and limited use, and are not suitable for carrying.

Therefore, there is also a screw-free development in the market, but the screw can achieve the purpose of freehand operation, but the shaft part is divided into two structural forms, or for some purposes (such as elasticity) in the pole If the inside of the body is made into a hollow state, the screw re-use rate drops sharply, and even it can be used only once, and this does not balance the structural strength of the screw itself.

Therefore, when the above screws are used, the following problems and defects are indeed to be improved:

First, when the locking action is performed, a large external force is required to insert the locked fastener, or it can be firmly fixed, so it is necessary to tighten by using a tool, which is inconvenient in operation.

Second, the structure itself requires greater rigidity, is prone to deformation, and has low reusability.

Third, it is impossible to balance the elasticity and structural strength.

Therefore, how to solve the above problems and deficiencies in the past, that is, the applicants of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the applicants of this new type have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, the design is simple and easy to operate. A new patented reusable, and easy to disassemble screw structure.

The main purpose of the present invention is to give the screw a certain degree of elasticity, and thereby use the hand pressure instead of the tool to lock the lock, and it can be easily removed by hand.

Another main purpose of the present invention is to strengthen the structural strength of the screw end, and to maintain the elasticity while avoiding permanent deformation, thereby prolonging the service life and increasing the reusability.

In order to achieve the above object, the structure of the present invention comprises: a top cap portion, a limiting base portion is formed on one side of the top cap portion, and a shaft portion is formed on a side of the limiting base portion facing away from the top cap portion, the shaft body The cross-sectional area of the portion is smaller than the cross-sectional area of the limiting base, and the shaft portion is formed with at least one latch portion for locking the locked fastener, and a rod is formed on the shaft portion. The body has an elastic perforation portion, and the end of the shaft portion facing away from the limiting base portion forms a reinforcing portion connecting the two sides of the shaft portion different from the perforated portion; when the user uses the new type as a fastener At the same time, the top cap portion is directly pressurized, and while the shaft portion is passed through the locked body, a perforation portion is formed in the center of the shaft portion, so that both sides of the shaft portion can be inwardly contracted and easily worn, and When the hand is released, the locked fastener is fixed by the click portion, that is, the locking action is completed. In addition, since the limiting base is not inserted into the locked fastener at the same time, the top hat portion and the locked fastener can be kept at a certain distance, so that the user can disassemble by hand, and the assembly is repeated many times due to the presence of the reinforcing portion. The shape of the shaft can still be maintained, thereby effectively achieving high reusability.

With the above technology, it is possible to achieve a practical advancement of the above advantages in view of the high cost of the conventional screw, the necessity of using tools to be disassembled, or the lack of structural strength due to elasticity, and the difficulty of repeated use.
