Description
Technical field
This utility model relates to self-tapping screw technical field, especially relates to a kind of New self-tapping screw.
Background technology
At present; self-tapping screw is used for thin metallic plate as the connection between the sheet material such as steel plate, saw plate; self-tapping screw is needed to be mounted rapidly and accurately; and can have firm attachment force; commonly used crossed countersunk head self-tapping screw; because its structural manufacturing process reason; when crossed countersunk head self-tapping screw uses instrument to apply moment of torsion effect; hair often can occur; i.e. crossed countersunk head groove can produce plastic deformation; moment cannot be applied again, also have some common hexagonal self-tapping screws owing to needing to add pad when some operating mode, increasing fastening force.
Summary of the invention
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of New self-tapping screw, and simple in construction, fastening effect are good, and for reaching above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of New self-tapping screw, specifically includes that screw head, screw rod, tail point and packing ring, and described screw rod is connected to bottom screw head, is provided with tail point bottom screw rod, and screw rod periphery is provided with screw thread and lower screw thread, and screw head is provided with the countersunk head groove coordinating screwdriver.
Such scheme, described upper screw thread is close thread form, and lower screw thread is for dredging thread form, and the thread of upper screw thread is more than lower screw thread, can be on the base material of practical two-layer different structure.
Such scheme, the ridge bottom surface of described lower screw thread is acclivitous cambered surface, and ridge end face is to recessed cambered surface, when backspin is installed, efficiently reduces resistance so that it is install more laborsaving.
Such scheme, described screw head and screw rod junction are provided with the strengthening sheet of circle, and strengthening sheet is provided with some strengthening muscle, can promote screw self-strength in the junction of screw rod.
Such scheme, described strengthening muscle equidistantly distributes at screw rod peripheral, is an inclined plane bottom strengthening muscle, and strengthening muscle makes screw head bear higher moment of torsion.
Such scheme, is provided with inside described packing ring and strengthens the bar groove that muscle matches, and strengthening muscle can agree with in bar groove.
Such scheme, described screw head is positive six prisms coordinating spanner to use, and countersunk head groove is cross, and countersunk head groove is available for Phillips screwdriver and straight screwdriver uses.
The beneficial effects of the utility model are:
1, the screw head of positive six prisms is provided with countersunk head groove at top, this screw can carry out rotating by screwdriver or spanner to be installed, can be further rotated by spanner to strengthen tightness, the most not only will not damage the countersunk head groove of screw head, and can have firm attachment force；
2, strengthening muscle and the strengthening sheet at self-tapping screw top can promote self-strength, it is possible to bearing bigger torsion, screw will not produce deformation easily；Upper screw thread that screw rod is peripheral and lower this pitch of screw thread and thread all differ, can be on the base material of practical two-layer different structure.
Accompanying drawing illustrates:
Accompanying drawing 1 is axonometric chart of the present utility model；
Accompanying drawing 2 is front view of the present utility model；
Accompanying drawing 3 is left view of the present utility model；
Accompanying drawing 4 uses state sectional view for this utility model.
Detailed description of the invention:
In order to make juror can the purpose of this utility model, feature and function be further understood that, hereby lift preferred embodiment and coordinate graphic detailed description as follows:
Refer to shown in Fig. 1 ~ 4, system is the structural representation of the preferred embodiment of this utility model, this utility model is a kind of New self-tapping screw, specifically include that screw head 1, screw rod 2, tail point 3 and packing ring 8, described screw rod 2 is connected to bottom screw head 1, being provided with tail point 3 bottom screw rod 2, screw rod 2 periphery is provided with screw thread 4 and lower screw thread 5, and screw head 1 is provided with the countersunk head groove 11 coordinating screwdriver: is provided with inside described packing ring 8 and strengthens the bar groove 81 that muscle 7 matches.
Such scheme, described upper screw thread 4 is close thread form, and lower screw thread 5 is for dredging thread form, and the thread of upper screw thread 4 is more than lower screw thread 5.Ridge 6 bottom surface of described lower screw thread 5 is acclivitous cambered surface, and ridge 6 end face is to recessed cambered surface, can be used on different base materials, change the size of screw thread and thread according to different base materials.
Such scheme, described screw head 1 and screw rod 2 junction are provided with the strengthening sheet 9 of circle, strengthening sheet 9 is provided with some strengthening muscle 7 in the junction of screw rod 2, strengthening muscle 7 equidistantly distributes at screw rod 2 peripheral, it is an inclined plane bottom strengthening muscle 7, in installation process so that it is screw head 1 and screw rod 2 stress are the most uniform, avoid damaging, thus increase screw head 1 and the service life of screw rod 2.
Such scheme, is provided with inside described packing ring 8 and strengthens the bar groove 81 that muscle 7 matches.Described screw head 1 is positive six prisms coordinating spanner to use, countersunk head groove 11 is cross, countersunk head groove 11 is available for Phillips screwdriver and straight screwdriver uses, countersunk head groove 11 transverse concave groove is longer than vertical groove, transverse concave groove is available for straight screwdriver and uses, this screw head 1 is available for multiple types of tools and uses, and countersunk head groove 11 and screw head 1 all will not produce deformation easily.
