Description
本發明係與一棘輪扳手結構有關,尤指一種棘輪扳手結構之制齒之咬合齒與棘輪部之囓合狀態係為二個端齒與棘輪部呈最囓合狀態,複數中間齒與棘輪部係呈部份嚙合狀態,最中間齒係呈最小嚙合狀態;該制齒係會有變形量,該二個端齒已與棘輪部呈最嚙合狀態,該制齒係會以複數中間齒為變形處,該二個端齒與複數中間齒即均會與棘輪部呈緊密囓合狀態。 The invention relates to a ratchet wrench structure, in particular to a ratchet wrench structure in which the meshing teeth and the ratchet portion are engaged with each other, wherein the two end teeth are in the most meshing state with the ratchet portion, and the plurality of intermediate teeth and the ratchet portion are In the partially engaged state, the most intermediate tooth system is in a minimum meshing state; the toothing system has a deformation amount, and the two end teeth are in the most meshing state with the ratchet portion, and the toothed system is deformed by a plurality of intermediate teeth. The two end teeth and the plurality of intermediate teeth are in close meshing state with the ratchet portion.
習用棘輪扳手結構之棘輪91及制齒92結構,如第九圖、第十圖及第十一圖所示,該習用棘輪91係設有棘輪部911,該制齒92係設有咬合齒921,該咬合齒921係與棘輪部911相嚙合,使該制齒92係可旋動棘輪91而旋動螺合件。 The ratchet wheel 91 and the tooth 92 structure of the conventional ratchet wrench structure are as shown in the ninth, tenth and eleventh drawings. The conventional ratchet 91 is provided with a ratchet portion 911, and the tooth 92 is provided with a snap tooth 921. The engaging teeth 921 mesh with the ratchet portion 911, and the teeth 92 can rotate the ratchet 91 to rotate the screw.
但此習用棘輪91及制齒92之缺失係在於: However, the missing of the conventional ratchet 91 and the tooth 92 is:
結構上該制齒92之咬合齒921係以單一圓心及單一弧面所組成,該咬合齒921之單一弧面及單一圓心係要配合棘輪91之棘輪部之圓心及外徑,因此該咬合齒921係全部與棘輪部911呈全嚙合狀態,該制齒92受本體旋動後,該制齒92係會產生變形,該制齒92之變形量係無法有其它空間適當轉移,旋動一段時間,該制齒92變形量累積後會使整個制齒92變形而與棘輪91間嚙合不完全。 The occlusal teeth 921 of the tooth 92 are composed of a single center and a single curved surface. The single curved surface and the single center of the engaging teeth 921 are matched with the center and outer diameter of the ratchet portion of the ratchet 91, so the occlusal teeth All of the 921 series are fully engaged with the ratchet portion 911. After the tooth 92 is rotated by the body, the tooth 92 is deformed, and the deformation amount of the tooth 92 cannot be properly transferred, and the rotation is performed for a while. When the deformation amount of the tooth 92 is accumulated, the entire tooth 92 is deformed and the meshing with the ratchet 91 is incomplete.
另一習用之棘輪扳手結構,如美國專利申請號:09/523625, 證書號:US6457387B1,台灣專利案申請號:089200570,專利名稱:棘輪扳手(二),該專利案結構係在於:一種棘輪扳手之換向塊30,該換向塊30一側分別設有第一齒面31及第二齒面32,該第一齒面31及第二齒面32係由二個不同圓心所形成之兩個弧率,其中以該兩圓心所形成之圓相交於一點,且兩圓心與上述相交點所形成之夾角小於30度。 Another conventional ratchet wrench structure, such as U.S. Patent Application No. 09/523625, Certificate No.: US6457387B1, Taiwan Patent Application No.: 089200570, Patent Name: Ratchet Wrench (2), the structure of the patent is: a reversing block 30 of a ratchet wrench, the first side of the reversing block 30 is respectively provided with a first The tooth surface 31 and the second tooth surface 32, the first tooth surface 31 and the second tooth surface 32 are two arc ratios formed by two different centers, wherein the circles formed by the two centers intersect at a point, and The angle between the two centers and the above intersections is less than 30 degrees.
該第一齒面31與棘齒211嚙合時,該第二齒面32係與棘齒211呈不嚙合狀,如此該換向塊30受力變形時,該第二齒部32處係可承受變形量,該換向塊30即有更佳之使用壽命,此即為此專利案相對習用制齒92之優點。 When the first tooth surface 31 is engaged with the ratchet teeth 211, the second tooth surface 32 is non-engaging with the ratchet teeth 211. When the reversing block 30 is deformed by force, the second tooth portion 32 can withstand The amount of deformation, the commutation block 30 has a better service life, which is the advantage of this patent relative to the conventional tooth 92.
但此專利案結構之缺失係在於: However, the lack of structure of this patent is based on:
1、該第一齒面31及第二齒面32係由二個不同圓心之兩個弧率,該第一齒面31或第二齒面32係分別與棘齒211囓合,該換向塊30基本上係為壓出成型或射出成型,該換向塊30之二個不同圓心之弧率於設計結構時需精準計算其數值及二個圓心間之間距,如有誤差即會造成缺失亦或無法與棘齒211完全囓合。 1. The first tooth surface 31 and the second tooth surface 32 are two arc ratios of two different centers, and the first tooth surface 31 or the second tooth surface 32 are respectively engaged with the ratchet teeth 211, and the commutation block 30 is basically extrusion molding or injection molding. The arc rate of two different centers of the reversing block 30 needs to accurately calculate the value and the distance between the two centers when designing the structure. If there is an error, the defect will be caused. Or it cannot be fully engaged with the ratchet 211.
2、該第一齒面31或第二齒面32係分別與棘齒211囓合,基本上第一齒面31嚙合之齒數即會較制齒92嚙合之齒數少基本上即會較習用之制齒92扭力較少。 2. The first tooth surface 31 or the second tooth surface 32 are respectively engaged with the ratchet teeth 211. Basically, the number of teeth meshed by the first tooth surface 31 is smaller than the number of teeth meshed by the teeth 92. The teeth 92 have less torque.
3、一般而言該棘輪扳手至少有二十種以上之規格尺寸,每一規格尺寸即需相同規格之換向塊30,該每一規格之換向塊30需設計二個不同弧率之第一齒面31及第二齒面32,該換向塊30相對制齒92即會增加很多之設計時間及成本。 3. Generally speaking, the ratchet wrench has at least 20 kinds of specifications, and each size requires the same size of the reversing block 30, and the reversing block 30 of each specification needs to design two different arc ratios. One tooth surface 31 and the second tooth surface 32, the commutation block 30 will add a lot of design time and cost to the tooth 92.
4、該換向塊30及制齒92係為粉未壓出成型或粉未射出成型,成型工法中一定多少有機率會產生變形缺失,習用之制齒92之咬合齒921係僅有單一 弧面及單一圓心即會產生變形機率而造成制齒92之不良品之損失,該第一齒面31及第二齒面32係有二個圓心及二個弧面,理論上即會有二倍之不良品損失。 4. The reversing block 30 and the tooth 92 are powder unpressed or powdered, and there is a certain amount of organic loss in the forming method. The bite 921 of the conventional tooth 92 is only single. The curved surface and the single center will cause a deformation probability and cause loss of the defective product of the tooth 92. The first tooth surface 31 and the second tooth surface 32 have two centers and two curved surfaces, and theoretically there will be two Double the loss of defective products.
