Description
Technical field
The utility model is related to technical field of hardware, specially a kind of double end self threading pin.
Background technology
Tapping screw, the entitled Self-tapping Screw of English be in the prebored hole of metal or nonmetallic materials from
Row, which attacks the one kind for drilling out negative thread joined together, threaded fasteners.Tapping screw is chiefly used in thin metallic plate（Steel plate, saw plate etc.）It
Between connection.When connection, thread Pilot hole first is made to connected piece, then tapping screw is screwed into the thread Pilot hole of connected piece
In.
Screw head shape has round end, tack, countersunk raised head and countersunk head etc..Material generally uses carburizing steel, material after heat treatment
Case hardness is not less than 45HRC.Compared with the screw thread of plain screw, in identical major diameter, screw pitch is big and path is then slightly smaller,
It has been standardized.Tapping screw material can be divided into two kinds of carbon steel and stainless steel, and mild steel material is usually with based on 1022 medium carbon steel.
Door and window is generally used for, on iron sheet.Its head is that the bearing surface for the part formation for increasing shape is made to thread forming and spiral shell in one end
Line cuts self-tapping screw（Self threading pin）For, flat counter-sunk head is oblate to immerse oneself in, coiled hair, and hexagonal and hexagonal Hua Sitou are mostly important,
This five kinds of head dummys account for all self-tapping screws almost 90% or more, use self-tapping screw（Self threading pin）It should first consider this.Another five kinds
Other patterns are the recessed bearing surface of flat-top, and the whole edge of flat-top, oblate recessed bearing surface, oblate whole edge and socket cap are more secondary head dummy, and
It immerses oneself in screw thread and is rolled into self-tapping screw in perfume top（Self threading pin）The selection of head dummy with it is upper same, use and main consider mushroom head, round end and 100
Degree flat counter-sunk head does not take for new design, and covering its function can be replaced by other head dummys, and coiled hair may replace mushroom head and round end,
82 degree of flat counter-sunk heads may replace 100 degree and put down as five kinds of flat-top, oblate top, coiled hair, turret head and hexagonal washer head.
The appearance of double end self threading pin facilitates the connection to two kinds of objects, convenient for object is fixed.
Currently, existing double end self threading pin connection effect is bad in the market, and it is not convenient enough when carrying out being screwed into connection, it is easy
Cause self threading pin that crooked phenomenon is installed, existing double end self threading pin load bearing effect is bad, and self threading pin is easy bending fracture.
Utility model content
The purpose of this utility model is to provide a kind of double end self threading pins, are designed using turret head, increase smooth bar part,
It is convenient when connection be screwed into, and does not easily cause self threading pin and installs crooked phenomenon, and load bearing effect is good, and self threading pin is not pliable disconnected
It splits.
To achieve the above object, the utility model provides the following technical solutions：A kind of double end self threading pin, including polished rod, institute
It states polished rod lower end and is fixedly connected with the first screw rod, first screw rod side end face is fixedly connected with self-tap, the polished rod upper end
It is fixedly connected with connecting rod, turret head is connected to by mounting hole fixing sleeve below the connecting rod side end face, in the connecting rod
End is fixedly connected with the second screw rod, and second screw rod side end face is fixedly connected with organic screw thread.
Preferably, the turret head maximum gauge is 16.5mm, minimum diameter 14.3mm, and a height of 6.35mm.
Preferably, the machine screw thread model 3/8-16UNC-2A.
Preferably, a length of 20mm of the second screw rod.
Preferably, a length of 25.4mm of the polished rod.
Preferably, the polished rod and the first screw rod overall length are 101.6mm.
Preferably, the overall long 133mm of double end self threading pin.
Preferably, the self-tap specification is 5/16 ".
Compared with prior art, the beneficial effects of the utility model are as follows：
Self-tap is connect with plank, and machine screw thread is connect with external connection body, is used for the connection of plank and other component, connection
Effect is good；Turret head is designed using hexagonal, and spanner easy to use is screwed into self threading pin, is held when solving existing self threading pin installation
Crooked phenomenon easily occurs；Polished rod and connecting rod play load bearing effect, and stressed effect is good, and self threading pin is not pliable or fractures.
