Description

Technical Field

[0001] The utility model relates to the technical field of pipeline assembly, in particular to a quick assembly clamp. Background Art

[0002] A clamp is a connection device that connects grooved pipes, valves and pipe accessories. It is used to tighten quick connectors. Its advantages over traditional flange, thread, welding and other connection methods are quick installation and convenient processing of the pipes or pipe fittings to be connected.

[0003] Conventional clamps are usually equipped with two bolts on both sides of the upper and lower clamps. Therefore, during installation, the clamp bolts need to be disassembled, the rubber ring is taken out of the clamp and put on the pipe or pipe fitting, and then the upper and lower pieces of the clamp are put on the outside of the rubber ring, and then the two bolts are tightened symmetrically to make it stuck in the groove on the pipe. This operation method is relatively complicated, and there are many parts to be disassembled and assembled, which not only increases the process and man-hours, but also makes it easier for parts to fall off, mismatch, and inappropriate installation.

[0004] The prior art uses a quick-release clamp that is tightened with only one bolt. Although the rubber ring can be taken out without disassembling the clamp, and the clamp can be put on the steel pipe and the bolts can be tightened to meet the requirements of tightening the clamp, when the clamp is put on the pipe as a whole, since the upper and lower clamps are only positioned and supported by the rubber rings, it cannot be guaranteed that the upper and lower clamps can be well positioned inside the groove of the pipe, and when the bolts are tightened, the openings of the upper and lower clamps are easy to clamp the compressed soft rubber ring. Therefore, in actual use, the operation time is not significantly reduced. Especially in more special scenarios, such as installation on the top of the floor, due to limited installation space, it is difficult for installers to check and confirm whether the upper piece is stuck in the groove, resulting in leakage of the clamp from time to time, which leads to rework at a later stage.

[0005] Based on the above reasons, the utility model designs a quick-assembly clamp, which, under the premise of tightening with a single bolt, utilizes a support ring on the same circumference as the clamp to assist in positioning the pipeline groove and prevent the rubber ring from being compressed and deformed, thereby ensuring the precise installation of the clamp, improving work efficiency and guaranteeing work quality. Summary of the invention

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a quick-assembly clamp, which, under the premise of tightening with a single bolt, utilizes a support ring on the same circumference as the clamp to assist in positioning the pipeline groove and prevent the rubber ring from being compressed and deformed, thereby ensuring the precise installation of the clamp, improving work efficiency and guaranteeing work quality.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a quick-assembly clamp, comprising an upper hoop and a lower hoop, support rings are respectively arranged at the symmetrical joints on both sides of the upper hoop and the lower hoop, rubber rings are arranged on the inner sides of the upper hoop and the lower hoop, and the clamping heads on one side of the upper hoop and the lower hoop are connected by a hook hinge.

[0008] The support ring is located on the same circumference of the upper hoop and the lower hoop.

[0009] Grooves for installing rubber rings are arranged on the inner circumferences of the upper hoop and the lower hoop and are communicated with the joint.

[0010] The radius of the upper and lower hoops is the same.

[0011] The clamps on the other side of the upper hoop and the lower hoop are connected by bolts.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By adding a support ring design at the symmetrical joints on both sides of the upper and lower clamps, when the upper and lower clamps are put on the pipe, the pipe groove can be positioned from the side, so that it can be operated by hand perception without naked eye observation. Since the support ring and the upper and lower clamps are on the same circumference, the support ring can assist the upper and lower clamps to avoid misalignment and distortion, and it is easier to cooperate with the rubber ring for accurate installation. At the same time, since the support ring can block the outside of the rubber ring, when tightening the bolt, the rubber ring will not be deformed by force and pressure, thereby improving the stability and sealing of the rubber ring. The utility model also connects the other side of the upper and lower clamps by means of a hook hinge, which can avoid the axial position deviation of the upper and lower clamps when they are separated and installed, and provides a certain amount of redundant adjustment space, which can assist the operator to quickly separate, position and install at each stage of installation, further improving the efficiency and quality of installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Description of reference numerals:

[0016] 1 is the upper hoop, 2 is the lower hoop, 3 is the support ring, 4 is the rubber ring, and 5 is the hook hinge. DETAILED DESCRIPTION

[0017] The utility model is now further described with reference to the accompanying drawings.

[0018] See also Figure 1 The utility model provides a quick-assembly clamp, comprising an upper hoop 1 and a lower hoop 2, support rings 3 are respectively arranged at the symmetrical joints on both sides of the upper hoop 1 and the lower hoop 2, rubber rings 4 are arranged on the inner sides of the upper hoop 1 and the lower hoop 2, and the clamping heads on one side of the upper hoop 1 and the lower hoop 2 are connected by a hook hinge 5.

[0019] The support ring 3 is located on the same circumference of the upper hoop 1 and the lower hoop 2 .

[0020] Grooves for mounting the rubber ring 4 are provided on the inner circumferences of the upper hoop 1 and the lower hoop 2 and are communicated with the joint.

[0021] The radii of the upper hoop 1 and the lower hoop 2 are consistent.

[0022] The clamps on the other side of the upper hoop 1 and the lower hoop 2 are connected by bolts.

[0023] Working principle:

[0024] The utility model does not require much debugging during operation. The upper and lower clamps are separated horizontally by means of a hook hinge 5 to take out the rubber ring 4 and the support ring 3 on one side. After the rubber ring 4 is put on the pipe to be installed, the lower hoop 2 is put on the lower side of the pipe and the taken out support ring 3 is installed. Then the upper hoop 1 is turned to the installation position and the support ring 3 is put into the upper hoop 1. Since the support ring 3 is on the side of the pipe and is on the same circumference as the upper and lower hoops, the position of the groove in the pipe can be assisted by hand touch. At the same time, the installation bolts are gradually tightened in accordance with the position of the rubber ring 4 to make the upper and lower hoops slowly bite. During the bite, adjustments can still be made according to the position change of the support ring 3. The whole process is in the same process flow, and there is no need to adjust the hand movement and position, which greatly ensures the accuracy and efficiency of the installation.
