Description

本考案は、プライヤーに係り、特にパイプ、ロッドなどの被工作物を操作するために用いられるプライヤーに関する。 The present invention relates to a pliers, and more particularly, to a pliers used for operating a workpiece such as a pipe or a rod.

従来のプライヤーは細長い脛部と、この脛部の一端に固定される固定顎と、この脛部の前記一端に前記固定顎に対して枢動可能に取り付けられる可動顎とを少なくとも含む。前記固定顎は、多数のロック歯を備える表面を有する。前記可動顎は、第一歯状面と第二歯状面を有する。前記可動顎の第一歯状面には、多数の第一係合歯が設けられ、前記可動顎の第二歯状面には、多数の第二係合歯が設けられる。したがって、被工作物は固定顎のロック歯と、可動顎の第一歯状面の第一係合歯と、可動顎の第二歯状面の第二係合歯との間でクランプされる。そのような方法で、可動顎はピボット方式で固定顎に対して枢動可能で異なったサイズの被工作物を固定することができる。 A conventional pliers includes at least an elongated shin part, a fixed jaw fixed to one end of the shin part, and a movable jaw pivotally attached to the one end of the shin part with respect to the fixed jaw. The fixed jaw has a surface with a number of locking teeth. The movable jaw has a first tooth surface and a second tooth surface. A number of first engaging teeth are provided on the first tooth-like surface of the movable jaw, and a number of second engaging teeth are provided on the second tooth-like surface of the movable jaw. Accordingly, the work piece is clamped between the locking teeth of the fixed jaw, the first engaging teeth of the first tooth surface of the movable jaw, and the second engaging teeth of the second tooth surface of the movable jaw. . In such a way, the movable jaw is pivotable with respect to the fixed jaw in a pivoting manner and can fix workpieces of different sizes.

しかし、可動顎の枢動可能な角度が所定値を超えるとき、固定顎のロック歯、可動顎の第一歯状面の第一係合歯、可動顎の第二歯状面の第二係合歯は、被工作物の表面を効果的に係合することができず、故に被工作物がプライヤーの固定顎と可動顎から容易に落ちることになり、その結果、ユーザに不便を招く。 However, when the pivotable angle of the movable jaw exceeds a predetermined value, the locking tooth of the fixed jaw, the first engagement tooth of the first tooth surface of the movable jaw, and the second engagement of the second tooth surface of the movable jaw. The artificial teeth cannot effectively engage the surface of the workpiece, so that the workpiece can easily fall from the fixed and movable jaws of the pliers, resulting in inconvenience to the user.

The first contact (P1) and the second contact (P2) of the first engagement tooth 210 of the first tooth-like surface 21 of the movable jaw 20 can generate a larger frictional force on the surface of the workpiece 30. it can. Therefore, the workpiece 30 can be clamped accurately and tightly by the fixed jaw 15 and the movable jaw 20, and slipping from the fixed jaw 15 and the movable jaw 20 can be prevented during operation of the pliers.

結局は、被工作物３０の表面における固定顎１５と可動顎２０のクランプ力を高めるために、固定顎１５と可動顎２０の特別な角度設計によって、固定顎１５のロック歯１５０の第一接点（Ｐ１）と可動顎２０の第一歯状面２１の第一係合歯２１０の第二接点（Ｐ２）は、被工作物３０の表面で、より大きい摩擦力を発生させることができる。したがって、被工作物３０を固定顎１５と可動顎２０によって正確かつ緊密にクランプすることができるとともに、プライヤーの操作間に固定顎１５と可動顎２０からスリップするのを防ぐことができる。また、ロック歯１５０、第一係合歯２１０および第二係合歯２２０の強度を高めるために、固定顎１５のロック歯１５０、可動顎２０の第一係合歯２１０と第二係合歯２２０が鈍角を持つように設計される。さらに、被工作物３０の変形によって被工作物３０が固定顎１５からスリップするのを防ぐために、固定顎１５のロック歯１５０の第一接線（Ｌ３と、固定顎１５のロック歯１５０のうち、接触しているロック歯１５０の一つと、がねじ山角度（Ａ）をなし、その角度が３７°と４５°の間にあるようにされている。 Eventually, in order to increase the clamping force of the fixed jaw 15 and the movable jaw 20 on the surface of the workpiece 30, the first contact of the locking tooth 150 of the fixed jaw 15 is achieved by the special angle design of the fixed jaw 15 and the movable jaw 20. (P1) and the second contact (P2) of the first engagement tooth 210 of the first tooth-like surface 21 of the movable jaw 20 can generate a larger frictional force on the surface of the workpiece 30. Therefore, the workpiece 30 can be clamped accurately and tightly by the fixed jaw 15 and the movable jaw 20, and slipping from the fixed jaw 15 and the movable jaw 20 can be prevented during operation of the pliers. Further, in order to increase the strength of the lock teeth 150, the first engagement teeth 210 and the second engagement teeth 220, the lock teeth 150 of the fixed jaw 15, the first engagement teeth 210 and the second engagement teeth of the movable jaw 20. 220 is designed to have an obtuse angle. Further, in order to prevent the workpiece 30 from slipping from the fixed jaw 15 due to deformation of the workpiece 30, the first tangent of the lock teeth 150 of the fixed jaw 15 (L3 and the lock teeth 150 of the fixed jaw 15 are One of the contacting lock teeth 150 forms a thread angle (A), which is between 37 ° and 45 °.

以上は本考案の好適な実施例と関連して説明されたが、本考案の技術範囲から逸脱せずに他の多くの可能な変更や変化をさせることができることが分かる。したがって、それらは本考案の実用新案登録請求の範囲に属するものとする。 Although the foregoing has been described in connection with a preferred embodiment of the present invention, it will be appreciated that many other possible changes and modifications can be made without departing from the scope of the present invention. Therefore, they belong to the scope of the claims for utility model registration of the present invention.
