[0024] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] As Figures 1 to 5 shown, the present utility model provides a pipe clamp, which includes an upper clamping plate 1 and a lower clamping plate 2. The upper clamping plate 1 includes a connecting portion 11, an upper clamping portion 12 and an upper locking portion 13 connected in sequence. The lower clamping plate 2 includes a bending portion 21, a lower clamping portion 22 and a lower locking portion 23 connected in sequence. A connecting hole 111 is provided at the end of the connecting portion 11. The bending portion 21 passes through the connecting hole 111 from the inside to the outside and then bends towards its own root, so that the upper clamping plate 1 is rotatably connected to the lower clamping plate 2. Both the upper clamping portion 12 and the lower clamping portion 22 are arc-shaped, and arc-shaped flexible steel wire gaskets 3 are provided on the inner sides of the upper clamping portion 12 and the lower clamping portion 22. The two flexible steel wire gaskets 3 jointly enclose a clamping space adapted to the pipe fitting 6. The upper locking portion 13 and the lower locking portion 23 are locked by a locking member 5 to fix the pipe fitting 6 located in the clamping space.

[0026] For the pipe clamp provided by the present utility model, the rotational connection between the upper clamping plate 1 and the lower clamping plate 2 is realized through the connecting portion 11 of the upper clamping plate 1 and the bending portion 21 of the lower clamping plate 2, making the assembly of the pipe clamp simpler and more labor-saving. By respectively providing flexible steel wire gaskets 3 on the inner sides of the upper clamping portion 12 of the upper clamping plate 1 and the lower clamping portion 22 of the lower clamping plate 2, the high-temperature resistance and corrosion resistance effects of the pipe clamp are improved, meeting the use conditions of the high-temperature pipeline of the engine. At the same time, the setting of the flexible steel wire gaskets 3 also makes the structure of the pipe clamp more compact, optimizes the overall structural strength and impact resistance of the pipe clamp, and improves the clamping firmness and reliability of the pipe clamp.

[0027] In this embodiment, the central angle of the upper clamping portion 12 is greater than the central angle of the lower clamping portion 22. With this setting, the contact area between the upper clamping portion 12 and the pipe fitting 6 is increased, further improving the clamping firmness and reliability of the pipe clamp.

[0028] In order to ensure the firmness and stability of the installation of the flexible steel wire gasket 3, an upper installation groove 121 is provided on the inner side of the upper clamping portion 12, a lower installation groove 221 is provided on the inner side of the lower clamping portion 22, the flexible steel wire gasket 3 of the upper clamping plate 1 is welded in the upper installation groove 121, and the flexible steel wire gasket 3 of the lower clamping plate 2 is welded in the lower installation groove 221.

[0029] In this embodiment, both the upper clamping plate 1 and the lower clamping plate 2 are castings, and a rounded corner transition portion 14 is provided between the upper clamping portion 12 and the upper locking portion 13. The angle a formed by the tangent line at the connection between the upper clamping portion 12 and the rounded corner transition portion 14 and the upper locking portion 13 is an acute angle. By providing the rounded corner transition portion 14, stress concentration is avoided, the strength of the upper clamping plate 1 is improved, and at the same time, the rounded corner transition portion 14 also facilitates demolding and is beneficial to mold manufacturing, avoiding cracking of the mold during quenching.

[0030] In order to further enhance the connection strength between the upper clamping portion 12 and the upper locking portion 13, a reinforcing rib 15 is also provided between the upper clamping portion 12 and the upper locking portion 13 in this embodiment.

[0031] In order to reduce the manufacturing difficulty, the connecting portion 11 and the upper clamping portion 12 are arranged to be tangent in this embodiment.

[0032] In order to facilitate connection, the connection hole 111 is set as a square hole in this embodiment. Of course, a round hole can also be used, and it is specifically selected according to actual requirements. This embodiment does not limit this.

[0033] In order to further reduce the manufacturing difficulty, the lower locking portion 23 and the lower clamping portion 22 are arranged to be tangent in this embodiment.

[0034] Since the oblong hole has more variability and adjustability than the round hole and can more easily adapt to different manufacturing and assembly requirements, locking oblong holes 4 are respectively provided on the upper locking portion 13 and the lower locking portion 23 in this embodiment, and the length direction of the locking oblong holes 4 is set to extend along the length directions of the upper locking portion 13 and the lower locking portion 23.

[0035] During use, open the upper clamping plate 1 and the lower clamping plate 2, place the pipe fitting 6 into the clamping space surrounded by the two flexible wire gaskets 3, and lock the upper locking portion 13 and the lower locking portion 23 through the locking member 5 to fix the pipe fitting 6.

[0036] The above is the preferred embodiment of the pipe clamp of the present utility model, and there are more embodiments not elaborated here. In summary, the pipe clamp of the present utility model is high-temperature resistant, corrosion resistant, has high clamping firmness and reliability, and meets the use conditions of high-temperature pipelines.

[0037] The present utility model is not limited to the above specific embodiments. All kinds of transformations made by those of ordinary skill in the art starting from the above concepts without creative labor fall within the protection scope of the present utility model.
