Accompanying drawing explanation
Fig. 1 is one of perspective view of an embodiment of a kind of screw of the present utility model;
Fig. 2 is the perspective view two of an embodiment of a kind of screw of the present utility model, which show nut inner side surface structure.
The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 2, propose an embodiment of a kind of screw of the present utility model, comprise the screw rod 200 that nut 100 and nut 100 center are extended downwards.Screw rod 200 inside is set to the cylindrical body 201 of hollow structure, cylindrical body 201 outer rim is provided with installs screw thread 202, nut 100 is set to hollow ring structure, nut 100 is evenly provided with the first groove 101 that 2N (N >=1) is individual and straight screwdriver is suitable, the upper-end surface of the annular of nut 100 and the junction surface of screw rod 200 hollow structure upper end are set to the inner side surface of reversed round bench shaped, inner side surface is provided with some second grooves 102 suitable with Phillips screwdriver, the integral hollow structure of screw.
Nut 100 is set to circle also can be set to hexagon, and can produce in batches according to the different demands of different client, appearance design is simply generous, washability is high, highly versatile.
Screw rod 200 inside is set to the cylindrical body 201 of hollow structure, and while meeting join strength, such design saves production material more than conventional screw, thus reduces the cost producing screw, has indirectly met the modern environmental protection low-carbon (LC) theory pursued.Cylindrical body 201 outer rim is provided with installs screw thread 202, and install the installation that screw thread 202 is applicable to worm structure, user in use succinctly can complete installment work rapidly.Nut 100 is set to hollow ring structure, saves production material further from structural design.Nut 100 is evenly provided with the first groove 101 that 2N (N >=1) is individual and straight screwdriver is suitable, the upper-end surface of the annular of nut 100 and the junction surface of screw rod 200 hollow structure upper end are set to the inner side surface of reversed round bench shaped, and inner side surface is provided with some second grooves 102 suitable with Phillips screwdriver.
First groove 101 quantity is 6 or 8, and the second groove 102 quantity is 4.
A kind of screw of the present utility model, combine the first groove 101 and the second groove 102 in one, in installation process, can be suitable for straight screwdriver, also can be suitable for Phillips screwdriver, simply very easy to use, versatility is extremely strong.Avoid in using process, when screw can only be used for straight screwdriver, only have the onerous conditions of Phillips screwdriver.The upper-end surface of the annular of nut 100 and the junction surface of screw rod 200 hollow structure upper end are set to the inner side surface of reversed round bench shaped, the inner side surface of inverted round stage structural design is while meeting join strength, production material is cost savings from structure, and inverted round stage designs simplification arranges the production process of second groove 102, and the easier adaptation of the structure of the second groove 102 and Phillips screwdriver also engages, the use of person easy to use.
The common screw of people is one overall, and the material generally selected major part is Ferrious material, the screw that Ferrious material is made have high strength, than great, the advantages such as magnetic, easily plating, easily forging processing can be inhaled, but also have that it easily gets rusty, adaptation is poor, cannot be locking etc. shortcoming.In recent years, developed a kind of screw be made up of plastic material, plastics screw has elasticity, easily injection moulding, the advantage such as durable in use and being widely used.
A kind of screw of the present utility model, integral hollow structure and select plastic material, easy injection moulding, has elasticity, durable in use.Meanwhile, the hollow structure designed by screw, while meeting join strength, also saves and produces material, reduces and produce old, selected the easy injection moulding of plastic material, facilitated large-scale production, greatly enhance productivity.
A kind of screw of the present utility model, comprises nut 100 and screw rod 200.Screw rod 200 inside is set to the cylindrical body 201 of hollow structure, cylindrical body 201 outer rim is provided with installs screw thread 202, nut 100 is set to hollow ring structure, nut 100 is evenly provided with the first groove 101 that 2N (N >=1) is individual and straight screwdriver is suitable, the upper-end surface of the annular of nut 100 and the junction surface of screw rod 200 hollow structure upper end are set to the inner side surface of reversed round bench shaped, inner side surface is provided with some second grooves 102 suitable with Phillips screwdriver, the integral hollow structure of screw.Screw of the present utility model, is set to hollow structure, while meeting join strength, save material, reduce cost of production, especially nut 100 is provided with first groove 101 suitable with straight screwdriver and second groove 102 suitable with Phillips screwdriver, and versatility is extremely strong.Design of Screw Thread, is convenient to the installation of screw thread.And, the integral hollow structure of a kind of screw of the present utility model and select plastic material, easy injection moulding, be easy to large-scale production, there is elasticity, durable in use.
