[0002] The Half Joint is a pipe repair device consisting of two main bodies and two rubber pads. It is mainly used for repairing leakage of the pipe part except the socket. It has the advantages of simple structure, easy installation and reduced repair costs.
[0003] When repairing a leaking pipe with a half joint, the two bodies installed on the pipe are connected by bolts and nuts. The two bodies clamp two rubber pads to seal the leaking part of the pipe. However, the bolts on the existing half joint are perpendicular to the pipe, such as Figure 1 As shown, when the pipeline is transporting liquid or gas, the pipeline will vibrate slightly. The vibration of the pipeline will gradually loosen the bolts and nuts on the half joint, which will cause the distance between the two bodies to gradually increase, the sealing effect of the two rubber pads to gradually decrease, and the leaking part of the pipeline will gradually start to leak again. Summary of the Invention
[0004] The embodiment of the present application provides a pipe clamp to solve the technical problem that the bolts and nuts on the existing half joint will gradually loosen due to the vibration of the pipeline, causing the leaking part of the pipeline to gradually start leaking again.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0023] The embodiment of the present application provides a pipe clamp, such as Figures 2 to 4 As shown, the pipe clamp includes two half-joint halves 100 , two sealing gaskets 200 , a first connecting ear 300 and a connecting structure 400 .
[0024] Two sealing gaskets 200 are respectively disposed on the inner side surfaces of the two half-joint halves 100. A first through-hole 310 is defined in the first connecting lug 300, and at least one first connecting lug 300 is provided on each of the two first side surfaces 110 of the half-joint perpendicular to its end surface. A connecting structure 400 is defined in the second through-hole 421, and at least one connecting structure 400 is provided on each of the two first side surfaces 110. The axis of the first through-hole 310 is perpendicular to the axis of the half-joint halves 100, while the axis of the second through-hole 421 is parallel to the axis of the half-joint halves 100.
[0025] For example, Figures 2 to 4 In the illustrated pipe clamp, each first side surface 110 is provided with two first connecting ears 300 and a connecting structure 400. Of course, the number of first connecting ears 300 and connecting structures 400 provided on each first side surface 110 can also be other numbers.
[0026] When a pipeline leaks, the pipe clamp is installed at the leaking area to seal it. Specifically, two half-joint halves 100 with sealing gaskets 200 on their inner sides are used to surround the leaking area of the pipeline. The first through-holes 310 and the second through-holes 421 on the two half-joints are aligned. Bolts are then passed through the two first through-holes 310 perpendicular to the pipeline's direction of extension and tightened with nuts. Bolts are then passed through the two second through-holes 421 parallel to the pipeline's direction of extension and tightened with nuts.
[0027] When the pipeline is vibrating due to liquid or gas transportation, and the bolts and corresponding nuts installed in the first through hole 310, as well as the bolts and corresponding nuts installed in the second through hole 421 become loose, the bolts located in the second through hole 421 can limit the movement of the two half joints in the direction perpendicular to the extension of the pipeline, so that the distance between the two half joint halves 100 remains unchanged, and the two sealing gaskets 200 are still pressed against the outer side of the pipeline by the two half joint halves 100, and the leakage of the pipeline remains blocked by the sealing gasket 200.
[0028] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the connection structure 400 includes a connection plate 410 and a second connection ear 420. The connection plate 410 is connected to the first side surface 110; the second connection ear 420 is connected to one end of the connection plate 410 and defines a second through hole 421.
[0029] The second connecting ear 420 is connected to the first side surface 110 via a connecting plate 410 . The connecting plate 410 allows the axis of the second through hole 421 formed on the second connecting ear 420 to be parallel to the axis of the half joint half 100 .
[0030] Furthermore, the connection structure 400 further includes a reinforcing rib 430 , which is disposed between the outer side surface of the half joint half 100 and the connection plate 410 .
[0031] When the bolts and nuts installed in the first through holes 310 become loose, the second connecting ears 420 and the connecting plate 410 are subjected to external forces. The reinforcing ribs 430 allow the connecting plate 410 to withstand large external forces without bending, further ensuring that the distance between the two half joint halves 100 remains unchanged.
[0032] For example, in Figures 2 to 4 In the embodiment, each connection structure 400 includes three reinforcing ribs 430 , which are spaced apart between the connection plate 410 and the outer side of the half section half 100 , and the connection plate 410 is connected to the outer side of the half section half 100 via the three reinforcing ribs 430 .
[0033] Continue to refer to Figures 2 to 4 Two first connecting ears 300 and a connecting structure 400 are provided on each first side surface 110 , and the connecting structure 400 is located between the two first connecting ears 300 .
[0034] like Figure 2 and Figure 3As shown, the two first connecting ears 300 connected to each first side surface 110 are respectively close to the two end surfaces of the half segment half 100; the connecting plate 410 is parallel to the first side surface 110 and extends to one of the first connecting ears 300. When the two half segment halves 100 are connected, the inner side surface of the connecting plate 410 connected to one half segment 100 is in contact with the first side surface 110 of the other half segment half 100.
[0035] This structure allows the connecting plate 410 to block the gap between the two half-joint halves 100, preventing dust from entering the gap and reducing dust contamination of the two gaskets 200. Furthermore, the contact area between the gaskets 200 and air is reduced, significantly slowing the oxidation rate of the gaskets 200 and extending their service life.
[0036] Reference Figures 2 to 4 The second connecting ear 420 is connected to a second side surface 411 of the connecting plate 410 that faces away from the half joint half 100 ; wherein the second side surface 411 is parallel to the first side surface 110 .
[0037] like Figure 3 As shown, the connecting plates 410 provided on the two first side surfaces 110 of the half joint 100 extend to the first connecting ears 300 close to different end surfaces respectively.
[0038] by Figure 3 Taking the orientation shown as an example, when the two connecting plates 410 are subjected to force, they can transmit the external force to the front half and the rear half of the half section 100 respectively through the reinforcing ribs 430, thereby preventing the situation where only the front half or only the rear half of the half section 100 is subjected to force, so that the force on the half section 100 is relatively uniform, and there is no need to design additional reinforcement structure for the front half or the rear half of the half section 100.
[0039] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
