Abstract

An adjustable water pipe clamp includes a first clamp unit and a second clamp unit. The first jaw unit includes a first body having two first connecting portions spaced apart from each other, and a positioning groove portion recessed by the inner side surfaces of the first connecting portions, the positioning groove portion having a chute section and a plurality of arcuate groove segments extending from one side of the chute section and spaced apart from each other. The second jaw unit includes a second body and a curved block. When the second clamping unit is in a clamping position relative to the first clamping unit, the curved clamping block is clamped to one of the arcuate groove segments to produce a clamping effect, and the second clamping unit is opposite to the clamping unit. When the first clamping unit is in an open position, the curved clamping block is separated from the curved groove segment and relatively slides in the sliding groove segment to adjust the clamping pipe diameter.

Description

Adjustable water pipe wrench

The utility model relates to a water pipe clamp, in particular to an adjustable water pipe clamp with a segment adjustment clamping pipe diameter.

Referring to Fig. 1 and Fig. 2, in order to facilitate the clamping of the pipe fittings of different pipe diameters, the user desires to have a water pipe clamp capable of adjusting the pipe diameter, and one of the existing adjustable water pipe clamps includes a first caliper arm 91. a second caliper arm 92, a pivoting shaft 93 pivotally connected to the first caliper arm 91 and the second caliper arm 92, and a pivoting portion of the pivot shaft 93 and the pivot shaft 93 and the The first caliper arm 91 is connected to the buckle spring 94.

The first caliper arm 91 includes a first body 911, a first grip 912 extending outwardly from an end of the first body 911, and a first body 911 extending away from one end of the first grip 912. The first clamp 913. The first body 911 has a through hole 914 therethrough.

The second caliper arm 92 includes a second body 921, a second grip 922 extending outwardly from one end of the second body 921, and a second body 921 extending away from one end of the second grip 922. The second clamp 923. The second body 921 has a surrounding wall 924 defining a through slot 925, and an abutting portion 926 is formed on one of the axial sides of the surrounding wall 924.

The pivot hole 914 extends through the pivot hole 914 of the first body 911 and the sliding slot 925 of the second body 921, and includes a latching portion 931 that is detachably attached to the abutting portion 926.

One end 941 of the buckle spring 94 is disposed on the pivot shaft 93 protruding from one end of the first caliper arm 91, and the other end 942 is connected to the end surface of the first caliper arm 91, as shown in FIG. The elastic force causes the engaging portion 931 of the pivot 93 to constantly abut against the abutting portion 926 of the surrounding wall 924.

Referring to FIG. 2, by rotating the first grip 912 to the second grip 922, the first clamp 913 can be rotated to the second clamp 923 and cooperate to produce a clamping effect. On the other hand, since the first caliper arm 91 moves toward the second caliper arm 92, the buckle spring 94 is pressed to cause the spring damper 94 to store an elastic restoring force and applied to the card abutting portion 931, and the card abutting portion 931 The abutting portion 926 is more firmly abutted, and the relative position of the second caliper arm 92 and the first caliper arm 91 is fixed, thereby achieving the effect of fixing the clamping pipe diameter and clamping the article.

Referring to FIG. 3 and FIG. 4, when the first grip 912 is rotated away from the second grip 922, the buckle spring 94 releases the elastic restoring force, so that the latching portion 931 slidably abuts the abutting portion. 926, and the relative position of the first clamp 913 and the second clamp 923 can be adjusted, thereby achieving the effect of adjusting the clamping pipe diameter.

However, in order to be wound around the pivot shaft 93, the diameter of the buckle spring 94 is narrow and the shape is small, and durability is a great test. If the buckle spring 94 is repeatedly subjected to the second clamp during use. When the arm 92 is driven and the metal is fatigued and broken, the adjustable water pipe clamp will lose the effect of adjusting the clamping pipe diameter, and if the buckle spring 94 accidentally falls off into the work site or the working machine, it will also cause work. Danger. On the other hand, the conventional adjustable water pipe clamp has many components, and the manufacturing and assembly costs are also high.

Therefore, the object of the present invention is to provide an adjustable water pipe clamp which is compact in construction, low in manufacturing cost, and improved in safety and durability.

Thus, the present adjustable water pipe clamp defines an auxiliary line and an axis perpendicular to the auxiliary line. The adjustable water pipe clamp comprises a first clamping unit and a second clamping unit.

The first jaw unit includes a first body extending along the auxiliary line, a first grip extending outwardly from an end of the first body, and a first body extending away from one end of the first grip The first clamp. The first body has two first connecting portions spaced along the auxiliary line, and one of the inner side surfaces adjacent to the first connecting portions, and a positioning groove portion recessed in a direction parallel to the axis. The positioning groove portion has a sliding groove section extending parallel to the auxiliary line, and a plurality of arcuate groove segments extending from one side of the sliding groove section and spaced apart from each other.

The second jaw unit includes a second body between the first connecting portions, a second grip extending outwardly from one end of the second body, and a second body away from the second grip a second clamp extending at one end, and an arcuate block extending from the side of the second body toward the first body and slidingly slidably disposed on the positioning groove portion.

When the second grip is rotated relative to the first gripper, the arcuate block is slidably engaged with one of the arcuate groove segments, and the second clamp is offset against the first The clamp generates a clamping effect, and when the second grip is away from the first grip, the second clamp is moved away from the first clamp, and the arcuate block is driven away from the arcuate groove segments And sliding relative to the sliding slot section to adjust the relative position of the second clamping unit and the first clamping unit.

The utility model has the effect that the effect of clamping the article and adjusting the diameter of the clamping pipe can be achieved by changing the arcuate block of the second clamp to slide and snap on the positioning groove portion of the first clamp. In addition, since the novel components are simplified, the manufacturing and assembly costs can be reduced, and there are no small and fragile components, so that the durability and safety can be improved.

Referring to FIG. 5 and FIG. 6 , an embodiment of the adjustable water pipe clamp of the present invention comprises a first clamp unit 1 and a second clamp unit 2 . An auxiliary line S passing through the first jaw unit 1 and an axis A perpendicular to the auxiliary line S are defined.
