Description
本實用新型涉及一種手動工具,且更具體地涉及一種具有鎖定機構的剪刀。 The utility model relates to a hand tool, and more particularly to a scissors with a locking mechanism.
剪刀,例如金屬剪刀,是一種用於通過剪切作用來切割金屬和其他材料的工件的手動工具,其一般用於各種製造業和建築施工任務。在使用金屬剪刀時,使用者一般通過操作剪刀的兩個樞軸連接的手柄以使刀片在打開和閉合狀態之間運動,從而對工件進行切割。在非工作狀態時,使用者可以利用金屬剪刀上附設的鎖定機構來鎖定金屬剪刀的手柄及刀片,以防止刀片進入張開狀態從而對其它物體產生損傷或傷害。然而,現有技術中的金屬剪刀上的鎖定機構往往不夠牢固,如此一來鎖定機構很可能輕易地被意外解鎖,這將增加在運輸和非使用狀態中金屬剪刀帶來的危險。 Scissors, such as metal scissors, are hand tools for cutting workpieces of metals and other materials by shearing, which are typically used in a variety of manufacturing and construction tasks. When using metal scissors, the user typically cuts the workpiece by operating the two pivotally connected handles of the scissors to move the blade between open and closed states. In the non-working state, the user can use the locking mechanism attached to the metal scissors to lock the handle and the blade of the metal scissors to prevent the blade from entering the open state and causing damage or injury to other objects.

Those skilled in the art will recognize that the hand tool according to the present invention may also be a tool for other uses, such as sewing scissors or scissors for food.
如圖1所示,剪刀10大體上具有第一剪切部分以及與第一剪切部分樞軸連接的第二剪切部分。第一剪切部分包括第一鉗口構件102、第一手柄116、第一手柄樞軸銷124、第一手握部120、第一刀片部106及第一延伸部108。第二剪切部分包括第二鉗口構件104、第二刀片部110、第二手柄118、第二手握部122、第二手柄樞軸銷126以及第二延伸部112。剪刀10還包括夾鉗樞軸元件114、中心樞軸銷128、扭簧130、以及鎖定機構132。 As shown in Figure 1, the scissors 10 generally has a first shearing portion and a second shearing portion that is pivotally coupled to the first shearing portion. The first shearing portion includes a first jaw member 102, a first handle 116, a first handle pivot pin 124, a first hand grip 120, a first blade portion 106, and a first extension 108. The second shearing portion includes a second jaw member 104, a second blade portion 110, a second handle 118, a second hand grip 122, a second handle pivot pin 126, and a second extension 112. The scissors 10 also includes a clamp pivot member 114, a central pivot pin 128, a torsion spring 130, and a locking mechanism 132.
應當理解的是,以上僅僅描述剪刀的基本結構。本領域的技術人員可以容易地理解到,在不脫離本實用新型的精神範圍,剪刀可以具有不同的設計或結合其它特徵。 It should be understood that the above merely describes the basic structure of the scissors. Those skilled in the art will readily appreciate that the scissors can have different designs or incorporate other features without departing from the spirit of the invention.
圖2示出剪刀的鎖定機構的分解圖。鎖定機構132包括致動器134、彈簧136、以及鎖定板138。致動器134具有沿軸向設置的基部140、第一凸出部142和第二凸出部144。其 中,所述基部140的橫截面面積較第一凸出部142的橫截面面積大,並且所述第一凸出部142的橫截面面積較第二凸出部144的橫截面面積大。致動器134還包括用於接收鎖定板138的一端148的槽146。彈簧136套在鎖定板138的端148上。當端148被接收在槽146內時,致動器134的底面150緊靠彈簧136,而彈簧136緊靠鎖定板138的邊緣152。鎖定板138包括部分邊緣開放的第一開口154和邊緣完全封閉第二開口156。第一開口154和第二開口156用於接收第一鎖定樞軸銷158和第二鎖定樞軸銷160。其中,鎖定板138通過第一開口154和第一鎖定樞軸銷158固定地樞轉連接於第一手柄116。 Figure 2 shows an exploded view of the locking mechanism of the scissors. The locking mechanism 132 includes an actuator 134, a spring 136, and a locking plate 138. The actuator 134 has a base portion 140, a first protruding portion 142, and a second protruding portion 144 which are disposed in the axial direction. its The cross-sectional area of the base portion 140 is larger than the cross-sectional area of the first protrusion portion 142, and the cross-sectional area of the first protrusion portion 142 is larger than the cross-sectional area of the second protrusion portion 144. The actuator 134 also includes a slot 146 for receiving one end 148 of the locking plate 138. Spring 136 is placed over end 148 of locking plate 138. When the end 148 is received within the slot 146, the bottom surface 150 of the actuator 134 abuts the spring 136 and the spring 136 abuts the edge 152 of the locking plate 138. The locking plate 138 includes a first opening 154 with a portion of the edge open and a second opening 156 that completely encloses the edge. The first opening 154 and the second opening 156 are for receiving the first locking pivot pin 158 and the second locking pivot pin 160. Wherein, the locking plate 138 is fixedly pivotally coupled to the first handle 116 by the first opening 154 and the first locking pivot pin 158.
在該實施例中扭簧130又稱為第二偏壓裝置,所述第二偏壓裝置適於沿第二方向進行對鎖定板138進行偏壓,從而使得在鎖定狀態時鎖定板138處於圖4中所示的位置。彈簧136又稱為第一偏壓裝置,所述第一偏壓裝置適於沿第一方向進行對致動器134進行偏壓,從而使得在鎖定狀態時鎖定板138處於圖5A和5B中所示的位置。 In this embodiment the torsion spring 130 is also referred to as a second biasing device adapted to bias the locking plate 138 in a second direction such that the locking plate 138 is in the locked state. The position shown in 4. Spring 136, also referred to as a first biasing device, is adapted to bias actuator 134 in a first direction such that in the locked state the locking plate 138 is in Figures 5A and 5B. The location shown.
圖3示出剪刀手柄的部分側視圖。第一手柄116上具有還具有開口162,致動器134從開口162向外突出從而使得使用者可以接觸並操作該致動器。 Figure 3 shows a partial side view of the scissors handle. The first handle 116 has an opening 162 thereon, and the actuator 134 projects outwardly from the opening 162 to allow the user to access and operate the actuator.
圖4至5D示出了剪刀處於鎖定狀態時的配置。在此狀態下,第二鎖定樞軸銷160接收於第二開口156內,因此鎖定板138同時連接於第一手柄116和第二手柄118,從而使得第一手柄116和第二手柄118不能相對於彼此發生樞轉。彈簧 136沿第一方向偏壓致動器134。如此以來,致動器134的基部140表面抵靠手柄的內表面而致動器134的第一凸出部142與開口162配合。 4 to 5D show the configuration when the scissors are in the locked state. In this state, the second locking pivot pin 160 is received within the second opening 156 such that the locking plate 138 is simultaneously coupled to the first handle 116 and the second handle 118 such that the first handle 116 and the second handle 118 are not relative Pivot in each other. spring 136 biases actuator 134 in a first direction. As such, the surface of the base 140 of the actuator 134 abuts the inner surface of the handle and the first projection 142 of the actuator 134 mates with the opening 162.
圖6至7B示出了剪刀處於解鎖狀態時的配置。在此狀態,鎖定板138沿方向B樞轉,第二開口156離開第二鎖定樞軸銷160。扭簧130偏壓鎖定板138。此外,致動器134的第一凸出部142表面抵靠手柄的內表面而第二凸出部144與開口162配合。 6 to 7B show the configuration when the scissors are in the unlocked state. In this state, the locking plate 138 pivots in the direction B and the second opening 156 exits the second locking pivot pin 160. The torsion spring 130 biases the locking plate 138. Further, the surface of the first projection 142 of the actuator 134 abuts against the inner surface of the handle and the second projection 144 mates with the opening 162.
在操作時,如果使用者想從鎖定位置向釋放位置移動,使用者首先要沿圖4中的方向A(所述第一方向的反方向)按壓致動器134,以克服彈簧136的偏壓並且使得致動器134的第一凸出部142與手柄開口162脫離配合。然後使用者沿方向B致動致動器134以使得鎖定板138沿方向B樞轉,從而被扭簧130偏壓在解鎖狀態。 In operation, if the user wants to move from the locked position to the released position, the user first presses the actuator 134 in the direction A (the opposite direction of the first direction) in FIG. 4 to overcome the bias of the spring 136. And the first projection 142 of the actuator 134 is disengaged from the handle opening 162. The user then actuates the actuator 134 in direction B such that the locking plate 138 pivots in direction B, thereby being biased by the torsion spring 130 in the unlocked state.
