New description: [New technical field] The new type is related to a screw design, especially a screw with fast locking speed and good locking force. [Prior Art] 10 15 It is common to laminate composite material 2 (such as rubber and wood) on j material 3 and use it after joining. There are many kinds of joining methods such as gluing, graves, screw locks, etc. In the case of U.S. Patent No. 6,666,638, the composite material 2 is joined to the wood 3 in a locking manner. - See Figure 2, which is a U.S. Patent No. 6,666,638, which is incorporated herein by reference to a composite material 2 (such as a mixture of rubber and wood) and wood 3 = wire 1, which has a screw head u One is disposed on the screw head ^ two rods: and a spiral ring is disposed on the thread unit ^ of the rod body 12, the rod body 12 is not fixed - the end is formed with - free end ΐ 2ι, hunger Uya Having a first tooth near the free end 121; 13"' and a second tooth opposite to the free end i2i, at the same time: the first two segments 131, 132 are not connected to each other, and the first segment (3) = right-hand thread 'and the second tooth segment 132 is a left-hand thread 13 and 132 is on the rod body 12 and is provided with a -bump 14 „ fit (4) FIG. 2, in the initial stage of the lock, the screw head is first applied u 'to drive the first-to-segment 131 to rotate the composite material 2: 2 and the outer diameter D1 of the thread is smaller than the outer diameter of the second tooth segment of the second tooth segment " the distance P1 is greater than The first i, ...: two! the stone, the pitch P2, and the first and second teeth are rotated to twist the first 20 M287887 5 10 15 the tooth segment 131 and then through the composite material 2 and screwed into the wood 3, this By the convex The ring of 14 is arranged such that the wood 3 is tightly joined to the composite material 2, and the second tooth segment 132 is also initially screwed into the composite material 2, and the second tooth segment 132 is designed to be cut by the left hand thread. Producing the complex: the fiber strip of material 2 and the chip of wood 3 are squeezed back into the composite material 2 and the wood 3 to complete the locking action. However, after continuous use, it is found that the US patent No. 6666638 remains There are unpainted good things' details as follows: 1 · Poor locking speed: Due to the large angle α of the screw of the first tooth segment, the composite material 2 cannot be quickly combined with wood 3 cutting into, easily lead to the wood fiber winding phenomenon of the wood 3, plus the outer diameter D2 of the second tooth segment is larger than the first tooth segment, and the second tooth segment 132 is a left hand thread, Therefore, the second segment 132 does not produce any cutting during the locking process, resulting in a more increased locking resistance, resulting in a significant reduction in the locking speed of the US Patent No. 6666638. 2. The fastening force is poor: _ 1 in 忒Outside the tooth segment is smaller, so only the first tooth after the lock is ^132 It is firmly fixed on the composite material 2, and the first tooth segment 131 cannot be effectively fastened to the Taiguq wood 3, resulting in the detachment of the composite material 2 from the wood 3. [New content] " □ This new type The purpose is to provide a screw that has the effect of increasing the locking speed and increasing the locking fastening force. 5 M287887 疋, the new type of screw, comprising a screw head, a rod body arranged on the screw head, and a screw green ί151, a threaded unit mounted on the rod body, wherein the rod body The one end is not fixed, but the small end has a free end, and the screw unit has a free end, and the fifth end of the free end is 5 10 15 • 20 ,, which is opposite to the free end. The second segment, at the same time, the first and second segments are not connected to each other, and the first and the segments are arranged in opposite directions, so that the first segment of the segment is cut by the male to increase the locking force. In addition to the catch, the second section of the brothers will be the composite material 盥 wood fiber strips and wood eyebrows no /, η back into the composite material, so that the fiber strips and wood chips are coated on the second tooth segment ^ ^ Around, the squat increases the locking fastening force so that the composite after the closure is intimately engaged with the wood.实施 [Embodiment] The following == the above and other technical content, features and effects, in the white (4) of the better _ the details of the slant, will be clear snail 1: read Figure 3 'this new screw 4 The preferred embodiment includes a shaft β on the sturdy 41, and a shackle of the shank 43 on the shank 42 and a free end 421 at the end. The trunk 42 is not fixed - 兮白山 and the thread unit 43 is described and has a first segment of the free end 421, with a near first-tooth p 432 .," End 421 广牙# "32, at the same time the first _, the second tooth segment, and the first segment 4 Ή total & not connected to each other is /Feng boat # is the right hand thread, and the second tooth segment 432 is the left hand Thread; in particular, the dentition of the second segment... The outer diameter D3 of the thread is larger than the outer ridge D4 of the snail, and the η is at the angle of the cusp of the second segment& The angle of the tooth peak is Θ, and at the same time, the 42-position M287887 of the rod body is provided with a - toothless section 44 in the first and second teeth section 43 432, and the pitch p4 of the first tooth section of the D Hai is smaller than the first The pitch of the segments is Μ. 5 10 With reference to Figure 4, the screw head 41 is first applied to the screw head during the initial lock-up: the third tooth segment 431 is driven into the composite material 5, and the thread is reached by the thread of the brother-segment The angle "sharp cutting effect produced by the small hand is used to effectively cut the fiber strip of the composite material 5, and then the I tooth segment 431 passes through the composite material 5 to screw into the wood 6 at this time. The edentulous section 44 is disposed such that the composite material 5 is tightly engaged with the wood member 6, and the outer diameter of the thread of the first tooth segment is compared with the outer diameter D4 A of the second tooth segment. Relatively, the first tooth segment 431 can accommodate the increase in chip volume, which will help to fasten the first tooth segment 431 to the wood 6. Moreover, while the edentulous segment 44 acts, the second segment 4 also begins to break into the composite material 5, and the outer diameter D4 of the second segment is conveniently small, and is reduced. The composite material 5 is contacted to increase the locking speed, and is designed with the left hand thread of the second tooth segment 432, so that the fiber strip and the wood chips generated by cutting the composite material 5 and the wood 6 are pressed back into the composite material 5 while By the elastic restoring force of the composite material 5, the squat fiber strip and the wood chips are wrapped around the second tooth segment 432, so that the second tooth segment 432 can be fastened to the composite material 5 to make the composite Material 5 is intimately joined to wood 6. From the above description, the present invention is compared with the conventional ones, and it can be known that the present invention has the advantages and effects listed below: 1 · Fast locking: 7 M287887 5 10 15 Locking early, Since the angle of the tooth peak of the first tooth segment is small, a sharp cutting effect can be produced in the locking over-twisting, and the fiber strip of the material of the male-cutting material and the wood fiber of the wood are effectively used. The θ:, the external sputum 1 乂 is small, so that the lock can be greatly reduced during the new locking process with the composite material. 2. Tightening force of the lifting lock: Since the outer diameter of the thread of the first tooth segment is relatively large, the volume of the first tooth segment can be increased by the amount of the chip, which will help to improve the first tooth segment tightness. Fixing on the wood, and #the composite material has an elastic restoring force, when the second tooth segment is screwed into the composite material, the second tooth segment is used to squeeze the fiber strip produced by cutting the composite material back. In the composite material, the second segment can also be fastened to the composite material to bond the composite tile.归 In summary, the new type of thread has a smaller outer diameter of the thread of the second tooth segment of the first tooth segment, so that the sharp (four) effect disk can be separately produced to reduce the friction effect, thereby greatly increasing the locking speed. At the same time, because the first tooth segment has a larger thread (4): the left hand thread design of the tooth segment, the composite material after the lock can be tightly joined with the wood, so the purpose of the novel can be achieved. However, the above descriptions are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, that is, the simple equivalent change of the present invention in accordance with the scope of the present patent application and the contents of the new specification. All should remain within the scope of this new patent. 20 M287887 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a US Patent No. 6,666,638; FIG. 2 is a schematic view of a locked state of the US Pat.
