Referring to fig. 1, the related art pipe clamp mainly includes a clamp ring having a one-side opening and a bolt locking assembly for adjusting the size of the opening of the clamp ring. The adjustable range of the opening size of the clamping ring is influenced by the range of elastic deformation of the clamping ring. The bolt locking assembly generally includes a bolt rotatably disposed on the clamp ring and a nut fixedly disposed on the clamp ring, the bolt and the nut being threadably coupled. The distance between the cap part of the bolt and the nut can be adjusted by rotating the bolt, so that the size of the opening of the clamping ring can be adjusted. When the pipe clamp is used, the clamping ring is sleeved on a pipe fitting to be clamped, and then the opening of the clamping ring is reduced by the bolt locking assembly so that the clamping ring clamps the pipe fitting, and therefore stable installation of the pipe clamp on the pipe fitting is completed.

However, in the actual disassembly and assembly process, in order to ensure the normal use of the clamping function, the opening size of the clamping ring is far smaller than the diameter of the pipe fitting, so that the pipe fitting is inconvenient to install into the groove seat in the clamping ring from the opening of the clamping ring, and the pipe clamp has the defect of inconvenient disassembly and assembly.

The first clamping groove 111 and the second clamping groove 112 are circular arc-shaped grooves so that the mounting cavity 11 is generally circular or oval in shape. The first clamp member 13 has a first hinge end 131 and a first open/close end 132, the second clamp member 14 has a second hinge end 141 and a second open/close end 142, the first hinge end 131 of the first clamp member 13 is hinged with the second hinge end 141 of the second clamp member 14, and the open/close opening 12 is formed between the first open/close end 132 of the first clamp member 13 and the second open/close end 142 of the second clamp member 14.

It is worth mentioning that the pipe clamp has an installed state and an adjusted state during actual use. In the installation state, the first clamping piece 13 and the second clamping piece 14 can rotate relatively to expand or contract the opening and closing opening 12, so that the pipe fitting can enter or leave the installation cavity 11 conveniently. In the adjustment state, the first hinge end 131 of the first clamping member 13 and the second hinge end 141 of the second clamping member 14 can be moved toward or away from each other, so as to adjust the diameter of the pipe member that can be clamped in the installation cavity 11.

Specifically, referring to fig. 3 and 4, the second hinge end 141 of the second clip member 14 is provided with a hinge lever 16, and an axis of the hinge lever 16 is a rotation axis between the first clip member 13 and the second clip member 14. The hinge rod 16 may be an elliptical rod or a round rod. When the hinge lever 16 is a round lever, a rotation limiting plane 161 for interference fit with the inner wall of the sliding groove 1512 is provided on the outer edge surface of the hinge lever 16. In this embodiment, the hinge rod 16 is a round rod, the number of rotation limiting planes 161 is two, and the two rotation limiting planes 161 are symmetrically disposed on the outer circumferential surface of the hinge rod 16.

Accordingly, the first hinge end 131 of the first clip member 13 may be provided with a hinge table 15 in an integrally formed manner, and the hinge table 15 is provided with a hinge runner 151 for cooperating with the hinge lever 16. Specifically, the hinge sliding groove 151 includes hinge hole portions 1511 for a running fit with the hinge lever 16 and a slip groove portion 1512 for a slip fit of the hinge lever 16, the number of hinge hole portions 1511 being at least two, all hinge hole portions 1511 being spaced apart in a direction approaching or separating from the first hinge end 131. The number of the sliding groove portions 1512 is at least one, the sliding groove portions 1512 extend in a direction away from the first hinge end 131 and toward the second hinge end 141, and two adjacent hinge hole portions 1511 are communicated through one sliding groove portion 1512. In the present embodiment, the number of hinge hole portions 1511 is two, the number of sliding groove portions 1512 is one, and one hinge hole portion 1511 is provided at each end of the sliding groove portions 1512.

In order for the clip tube to have a stable installation state and an adjustment state, the hinge lever 16 needs to slide only in the sliding groove portion 1512 and rotate only in the hinge hole portion 1511. Accordingly, the groove width D of the sliding groove portion 1512 is smaller than the aperture R of the hinge hole portion 1511, and the distance between the two rotation limiting planes 161 on the hinge lever 16 is slightly smaller than the groove width D of the sliding groove portion 1512 so that the hinge lever 16 can slide only in the sliding groove portion 1512.

It should be noted that, under the influence of the installation range of the pipe clamp, the angle β formed by the rotation between the symmetry line L1 of the first clamping piece 13 and the symmetry line L2 of the second clamping piece 14 is generally not greater than 270 ° in the actual installation process of the pipe clamp, that is, the angle β is generally less than or equal to 270 ° when the clamping ring 1 is in the installation state. Therefore, in the present embodiment, when the adjustment state is defined, the angle β formed by the rotation between the symmetry line L1 of the first clamp member 13 and the symmetry line L2 of the second clamp member 14 is generally larger than 270 °. Accordingly, in order for the first clamp member 13 to slide only in the adjusted state, the angle α between the symmetry line L2 of the second clamp member 14 and the plane of rotation limiting plane 161 is a right angle or an acute angle. When the hinge lever 16 is located in the sliding groove portion 1512, the symmetry line of the first clamp member 13 and the plane of the rotation limiting plane 161 are approximately parallel, so that an angle β formed by rotation between the symmetry line L1 of the first clamp member 13 and the symmetry line L2 of the second clamp member 14 can be equal to or greater than 270 °.
