Pipe bundle ring disassembly clamp

The present invention relates to a pipe clamp bundling and disassembling pliers, in particular to a stable fitting and positioning with a hooking portion of the pipe bundle loop and a reinforcing flange provided on the outer edge of the card protrusion portion, so as to improve the smooth assembly and disassembly of the pipe bundle ring. Convenient pipe fittings and detachable pliers.

According to the existing engineering and other pipeline assembly, it is often necessary to connect a plurality of pipe fittings to extend the length of the overall pipeline. In general, the pipe fitting method is to connect the pipe with a larger diameter and the pipe with a smaller pipe diameter, but this connection mode, Since there is no leak-proof or anti-loose structure at the pipe socket, the gas or liquid circulating in the pipe often occurs during use, and the pipe fitting is leaked, and even two sets of pipe joints are detached. Set a danger.

Therefore, some manufacturers have developed a beam loop for pipe fittings, so that the two pipe joints are tightly fastened by a bundle of loops. The existing pipe bundle ring system is mainly bent and formed in a ring shape by a metal plate piece, and the metal plate piece is formed with a hook at one end. a buckle portion, and a protruding portion is protruded from the other end of the metal plate to buckle with the hook portion, so that the metal plate forms a closed loop, and the metal plate is in the hook portion thereof And an embossed reinforcing flange is formed on each of the outer edges of the card protrusions, whereby the tube bundle sleeve is sleeved at the joint of the two tube members, and the joints of the two tube members can be tightened to prevent fluid leakage inside the tube member or The pipe is detached and the like.

Another manufacturer has developed a special disassembly and assembly pliers for the tube bundle ring. The disassembly and assembly pliers are mainly provided with a first caliper arm and a second caliper arm, and the two tong arms are overlapped, and the pivoting mechanism is pivoted. A spring is arranged between the two tong arms, and the two ends of the spring are arranged to be positioned on the two tong arms, and the two tong arms are formed at one end to form a jaw, and each of the two jaws is provided with a cocking portion, and the first tong is provided A trough is formed at the center of the arm of the arm. Here, when used, the tube bundle is sleeved at the joint of the two tubes, and the special disassembly clamp is taken to the first clamp arm and the first The nipper of the second tong arm abuts against the hook portion of the tube bundle ring and the outer edge of the card protrusion portion, and the rear hand is held at the other end of the first tong arm and the second tong arm to make the first tong The arm and the second caliper arm are clamped to the hook portion of the tube bundle ring and the protruding portion of the tube clamp, so that the tube bundle ring is condensed, and the hook portion and the card protrusion portion at both ends of the tube bundle ring are buckled and fixed. According to this, the tube bundle loop is used to tighten the joints of the two tubes.

However, when the swaying portion of the first tong arm of the existing pipe yoke attachment tongs abuts against the outer edge of the hooking portion, the groove provided in the center of the swaying portion can be embossed at the outer edge of the hooking portion. The reinforcing flange is fitted so that the first caliper arm does not slip off the hook portion when the urging portion of the first caliper arm is applied to the hook portion, but the damper portion of the second caliper arm only In the form of a simple insertion piece, when the second clamping arm of the insertion piece abuts against the reinforcing flange of the outer edge of the protruding portion, the reinforcing flange is in point contact with the reinforcing flange so that the second clamping arm When the swaying portion is biased by the knuckle portion, the slippage of the knuckle portion is often caused, and the hooking portion and the knuckle portion cannot be smoothly fixed, resulting in considerable inconvenience in use.

The reason is that the creator of the present invention has the experience of the manufacturing and design experience and knowledge of the related fields, and has been assisted by many years, in view of the fact that the existing pipe fittings and detachable tongs are easily slipped off between the pipe bundles and the like. Ingenuity, research and creation of this creation.

The present invention relates to a pipe clamp bundling and disassembling pliers, and the main purpose thereof is to provide a stable fitting and positioning with a reinforcing flange provided on the hook portion of the pipe brace and the outer edge of the bucking portion to improve the pipe collar Disassemble and install the pipe fittings and disassembly clamps for smooth and convenient.

In order to achieve the above-mentioned implementation, the present inventors have developed the following tubular collar detachable tongs, which mainly include a first caliper arm and a second caliper arm, so that the first caliper arm and the second caliper arm overlap each other, and The first caliper arm and the second caliper arm overlap and pivotally extend, and an elastic member is disposed between the first caliper arm and the second caliper arm, and the two ends of the elastic member are respectively disposed on the first Positioning a caliper arm and a second caliper arm, and forming one end of the first caliper arm and the second caliper arm to form a jaw end, and forming the other end of the first caliper arm and the second caliper arm to form a grip end, and The first ram arm and the second caliper arm respectively have a first swaying portion and a second swaying portion at a nip end thereof, and the first damper portion and the second caliper arm of the first caliper arm are The second swaying portions are corresponding to each other, and the one end surface of the first swaying portion and the second swaying portion are formed with an abutting slope surface, and the first cocking portion is opposite to the second cocking portion. a first recessed groove is recessed in the center of one end surface; and the feature is:

The second swaying portion is recessed with a second recess at a center of one end surface opposite to the first swaying portion, and the first splicing portion of the first swaying portion and the second swaying portion are The second slot position corresponds.

The pipe harness detachable tongs as described above, wherein the first sway portion has a first grooved portion corresponding to the second swaying portion of the second swaying portion.

The tubular collar detachable tongs as described above, wherein the elastic member is a torsion spring, and the elastic member is wound around the pivot shaft, and the inner surface of the first caliper arm and the second caliper arm is formed The groove is disposed such that the two ends of the elastic member are respectively positioned against the grooves of the first and second tong arms.

The tubular collar detachable forceps as described above, wherein the first caliper arm and the second caliper arm have a jaw end end recessed adjacent to the first swaying portion and the second swaying portion The housing department.

Therefore, when the present invention is used for the engagement and separation of the tube bundle loop, the first and second recessed grooves are provided by the first flap portion and the second flap portion, so that the tube bundle loop can be hooked. The reinforcing flange is fixedly positioned at the outer edge of the portion and the protruding portion of the card, so that when the first swaying portion and the second swaying portion actuate the hooking portion and the knuckle portion, no slippage occurs, and accordingly,俾 It is indeed effective to improve the smoothness and convenience of the assembly and assembly of the tube bundle.

In order to make the technical means of this creation and the effect it can achieve, it can be more completely and clearly disclosed. For details, please refer to the following diagrams and drawings:
