Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically, to a clamp connector. Background Art

[0002] In pipeline installation construction, there are various pipeline connection processes, such as: threaded connection, welding, flange connection, ferrule connection, press connection, socket connection, and clamp connection, etc. Among them, clamp connection is a relatively common connection method. In order to make the clamp be firmly fixed on the pipeline, the surfaces at both ends of the connected pipelines are usually pressed into a groove shape. Therefore, clamp connection is also called grooved connection.

[0003] At present, a clamp connector is composed of two semi-circular clamp pieces. The semi-circular clamp pieces are usually integrally bent and formed. The parts bent and extended from the two semi-circular clamp pieces correspond to each other and are fixed at the pipeline connection by bolts to achieve the connection between pipelines. However, for most of the existing clamp connectors in order to improve the strength and connection effect, the connecting parts bent and extended from the two semi-circular clamp pieces usually weld gaskets to improve the strength and connection effect at the connection. After the gasket is welded, not only does the workload increase, but also the welded clamp connector is not beautiful. Summary of the Utility Model

After the gasket is welded, not only does the workload increase, but also the welded clamp connector is not beautiful.

[0006] 2. Technical Solutions

[0007] To solve the above problems, the utility model adopts the following technical solutions:

[0008] A clamp connector includes two semi-circular clamp pieces. Both of the two semi-circular clamp pieces are integrally bent and formed, and the two semi-circular clamp pieces are matched with each other. Each semi-circular clamp piece includes an arc-shaped clamping plate, two planar connecting plates, and two planar bending edges. The two planar connecting plates are respectively arranged on the symmetric sides of the arc-shaped clamping plate, and the two planar bending edges are respectively arranged between the two planar connecting plates and the arc-shaped clamping plate.

[0009] As a preferred embodiment of the present utility model, each of the planar connecting plates includes a connecting portion, a reinforcing portion, a reinforcing bending edge, and two sets of bolt holes. The connecting portion is disposed on one side of an arc-shaped clamping plate, the reinforcing portion is disposed on one side of the connecting portion, the reinforcing bending edge is disposed between the connecting portion and the reinforcing portion, and the two sets of bolt holes are respectively opened on the connecting portion and the reinforcing portion, and the two sets of bolt holes correspond to each other.

[0011] 3. Beneficial effects

[0012] Compared with the prior art, the advantages of the present utility model are as follows:

[0013] 1) In this solution, the semi-circular clamp is bent through the planar bending edge to form an arc-shaped clamping plate and a planar connecting plate. The planar connecting plate is bent through the reinforcing bending edge to make the connecting portion and the reinforcing portion fit together, thereby improving the connection strength and connection effect of the planar connecting plate. In the present utility model, by adjusting the length of the planar connecting plate after bending, the planar connecting plate can be bent a second time. The second bending thickens the connection part of the semi-circular clamp. The method of bending and strengthening reduces the workload, and at the same time increases the connection strength and connection effect of the connection part, ensures the stability of the connection of the two semi-circular clamps, prevents pipeline leakage, and moreover, the method of bending and strengthening can also keep the connecting piece beautiful.
