Description
本發明係有關於一種擴管器。 The invention relates to a pipe expander.
按,一般擴管器之結構係如專利TWM256241中所揭露,其至少包含有一本體與二夾塊,該二夾塊之間形成有插槽且可對應設於該本體之底部,該本體穿設有一螺栓,該螺栓可旋轉升降,藉由使用轉動工具(如電動工具或氣動工具)正轉以將夾設於該二夾塊之間之管件抵頂進行擴管作業。然而,當執行完擴管作業而欲拆卸時,需先將螺栓逆轉,而若使用轉動工具進行逆轉時,若螺栓逆轉至終點時,會因為螺栓無法再進行逆轉而轉動工具仍持續轉動,導致使用者之手部被轉動工具帶動造成扭傷,存在亟待改善之缺弊。 According to the general structure of the pipe expander, it is as disclosed in the patent TWM256241. It includes at least a body and two clamping blocks. A slot is formed between the two clamping blocks and can be correspondingly located at the bottom of the body. The body is passed through There is a bolt, which can be rotated and lifted. By using a rotating tool (such as an electric tool or a pneumatic tool) to rotate forward, the pipe fitting sandwiched between the two clamping blocks can be pressed against the top to perform the pipe expansion operation. However, when the pipe expansion operation is completed and the bolt is to be disassembled, the bolt needs to be reversed first. If a rotating tool is used for reversal, if the bolt is reversed to the end point, the bolt will no longer be able to be reversed and the rotating tool will continue to rotate, resulting in The user's hand is sprained by the rotating tool, which has shortcomings that need to be improved urgently.
因此,有必要提供一種新穎且具有進步性之擴管器,以解決上述之問題。 Therefore, it is necessary to provide a novel and progressive pipe expander to solve the above problems.
本發明之主要目的在於提供一種擴管器,具有單向空轉之功能,可避免使用者使用轉動工具時不甚扭傷,且又容易進行復位,以增加工作效率。 The main purpose of the present invention is to provide a pipe expander with a one-way idling function, which can prevent the user from being sprained when using a rotating tool, and is easy to reset, thereby increasing work efficiency.
為達成上述目的,本發明提供一種擴管器,包括一本體、一驅動組件及複數彈性件。該本體沿一軸向設有一第一螺紋部。該驅動組件設有一第二螺紋部,該第一螺紋部與該第二螺紋部相螺接。該等彈性件環繞排列於該驅動組件,並設於該驅動組件與該本體其中一者,當該第一螺紋部與該第二螺紋部相螺動而使該第一螺紋部與該第二螺紋部相脫離時,該等彈性件直接或間接地抵頂於該驅動組件與該本體之間,以使該第一螺紋部與該第二螺紋部具有相靠近之趨勢。 In order to achieve the above object, the present invention provides a pipe expander, which includes a body, a driving component and a plurality of elastic members. The body is provided with a first threaded portion along an axial direction. The driving component is provided with a second threaded part, and the first threaded part is screwed with the second threaded part. The elastic members are arranged around the driving component and are provided on one of the driving component and the body. When the first threaded part and the second threaded part are screwed, the first threaded part and the second threaded part are screwed together. When the threaded parts are disengaged, the elastic members directly or indirectly abut between the driving component and the body, so that the first threaded part and the second threaded part have a tendency to approach each other.
