Description

Tubing Connector Removal Tool

The present invention relates to hand tools, more specifically, to a tool for disassembling oil pipe joints.

All kinds of pipe fittings rely on the joint to achieve the purpose of stable insertion. In order to facilitate disassembly and replacement, the joint is usually made detachable from the pipe fitting. For example, push-in joints are generally used to assemble in the fuel supply pipe, fuel return pipe, evaporation pipe hose, steel pipe or tubular device of the fuel system, and have the advantages of convenient disassembly and reliable use. When the quick-plug connector is disassembled, it is necessary to apply pressure on the two compression locks of the connector to loosen the connection and pull it out axially to realize disassembly and separation. At present, when disassembling and separating the pipeline quick-plug connector, the method of manual disassembly is mainly adopted, and the pressing buckle is pressed manually or by using pliers.

In view of the above requirements, the present invention proposes an oil pipe joint disassembly tool, which has the functions of being easy to hold, preventing hand loss, easy to operate and apply force, favorable for force transmission, and effective in pressing and clamping force, so as to achieve the effect of disassembling oil pipe joints with stable force. Purpose.

The rear end is provided with a pair of elastically stretchable short arms through a second pivot; the long arms include a first arm and a second arm, the first arm and the second arm are connected by a The joint shaft is pivotally connected; the short clamp arm also includes a first arm and a second arm The arm hand, the first arm hand of the short pliers arm and the second arm hand of the short pliers arm are integrally connected; the relative distance of the two long pliers arms is from the center point of the first pivot. The opening to the joint axis is the maximum opening degree, and the relative distance from the joint axis to the free end of the long clamp arm is gradually reduced; the relative distance of the two short clamp arms is from the center point of the second pivot. The maximum opening is to the free end of the short clamp arm; the opening of the free ends of the two long clamp arms is greater than the opening degree of the free ends of the two short clamp arms; the straight line length of the two long clamp arms out of the body is defined as L1, the straight line length of the two short clamp arms extending out of the body is defined as L2, and the length of the body is defined as L3; wherein, the length of the body is 8 to 10 cm; L1: L2: L3=2:1:2 .

Based on the above technical features of the present invention, the present invention has the following effects: when the user holds the main body and operates the long pliers arm, the maximum opening of the short pliers arm can be stopped at the hand in a timely manner; otherwise, using When the user holds the main body and operates the short clamp arm, the maximum opening of the long clamp arm can timely stop the hand, thereby helping the user to hold the body more stably and prevent the hand from falling off.

According to the opening configuration of the long and short tongs arms and the length ratio configuration of the long tongs arm, the short tongs arm and the main body of the present invention, the long tongs arms and the short tongs arms can play the role of labor-saving levers, and the present invention can be used to operate When the user's thumb and index finger are pinched, the best position for pinching is at the junction of the first arm and the second arm of the long or short clamp arm, so that favorable force transmission can be achieved so that the long clamp arm and the The short caliper arm expresses effective clamping force to disassemble the oil pipe joint with stable force.

The first pivot axis or the second pivot axis hides the end of the first arm of the long pincer arm (or the short pincer arm) in the body to form a connection relationship, in other words, the long pincer arm (or the short pincer arm) The connection with the body is hidden inside the body and not exposed, and the connection relationship is protected by the body and not exposed. The exposed connection will affect the user's feel of holding the body.
