Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aerospace manufacturing, in particular to a special clamp for aviation pipelines. Background Art
[0002] In aircraft manufacturing, the environmental control system is responsible for maintaining a suitable ambient temperature in the cockpit, passenger cabin, cargo hold, equipment compartment and other areas by transmitting air of different temperatures through the piping system.
[0003] However, because aircraft experience a variety of complex environmental conditions during operation, such as vibrations caused by high-speed flight and airflow shock between different pressure zones, extremely high requirements are placed on the stability and reliability of the piping. If the piping is not securely fixed or easily loosens, it will affect the normal operation of the environmental control system and pose a safety hazard.
[0004] At present, most pipelines are installed and fixed using simple clamps and other methods. Although the pipeline can be fixed to a certain extent, the following technical problems still exist: the simple clamps are in hard contact with the pipeline. In order to ensure the fixing effect of the pipeline, excessive pressure is often applied to the pipeline, which will cause the pipeline to deform and thus affect its service life. In addition, under complex environmental conditions such as vibration and airflow impact, the friction between the simple clamps and the pipeline is insufficient, and the pipeline may not be able to maintain stability, posing a risk of loosening.
[0005] In view of this, the present utility model is proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a clamp specifically designed for aviation piping, addressing the technical issues of existing simple clamp designs, such as hard contact with the pipeline, excessive pressure on the pipeline, and deformation, which in turn shortens its service life.

[0026] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0027] like Figure 1-3 As shown, the utility model provides a special clamp for aviation pipelines, including a clamp body and a rubber gasket 5. The clamp body includes a clamping component 1, the clamping component 1 has a clamping space, and a positioning groove 11 is provided on the inner wall surface of the clamping space. A positioning protrusion 51 adapted to the positioning groove 11 is provided on the side of the rubber gasket 5 facing the clamping space, so that the rubber gasket 5 is embedded in the inner wall surface of the clamping component 1, and a friction protrusion 52 is provided on the side of the rubber gasket 5 facing away from the clamping space.
[0028] The present invention incorporates a rubber gasket 5 embedded within the inner wall of the clamp assembly 1. As a soft material, the rubber gasket 5 acts as a buffer between the clamp body and the pipeline, reducing direct, hard contact and excessive pressure on the pipeline, preventing deformation and extending the service life of the pipeline. Furthermore, friction protrusions 52 are provided on the rubber gasket 5 to increase friction with the pipeline, improving the stability and reliability of the pipeline in complex environments.
[0029] As an optional embodiment, the clamp body also includes a first wing plate 2 and a second wing plate 3, which are respectively connected to the open ends of the clamping assembly 1, and the first wing plate 2 and the second wing plate 3 are correspondingly arranged so that when the first wing plate 2 and the second wing plate 3 abut against each other, the clamping space is in a closed state.
[0030] The abutment between the first wing plate 2 and the second wing plate 3 increases the fastening force of the clamping assembly 1 on the pipeline, so that the pipeline remains stable in a complex environment and is not easily loosened.
[0031] As an optional embodiment, connecting holes 8 are correspondingly opened on the first wing plate 2 and the second wing plate 3 .
[0032] Fasteners such as bolts are sequentially passed through the connection holes 8 of the first wing plate 2 and the second wing plate 3 to firmly connect the first wing plate 2 and the second wing plate 3 together to ensure the closedness and fastening force of the clamping space.
[0033] As an optional embodiment, the first wing plate 2 extends along the tangential direction of the clamping assembly 1 to form a straight structure.
[0034] This arrangement allows the first wing plate 2 to provide a more stable support surface, allowing the clamp body to be evenly stressed when tightening the pipeline. It also facilitates placing the clamp body and pipeline on a horizontal surface, simplifying the operation process and improving work efficiency.
[0035] As an optional embodiment, avoidance grooves 6 are provided on the outer wall surfaces of the connection points between the first wing plate 2 and the clamping assembly 1 and between the second wing plate 3 and the clamping assembly 1 .
[0036] When carrying out the installation or adjustment of pipeline, the avoidance groove 6 provides enough operating spaces for the operator's hand and operating tools. In addition, the avoidance groove 6 also plays the effect of weight reduction.
[0037] As an optional embodiment, the inner wall surface of the clamping assembly 1 transitions obliquely to the inner wall surfaces of the first wing plate 2 and the second wing plate 3 , respectively, to form an inclined surface 4 .
[0038] Furthermore, there is a smooth transition between the inclined surface 4 and the inner wall surface of the clamping assembly 1, the inner wall surface of the first wing plate 2 and the inner wall surface of the second wing plate 3. The pipeline can slide smoothly into the clamping space along the guidance of the inclined surface 4, reducing the difficulty of installation.
[0039] When the first wing plate 2 and the second wing plate 3 are in contact, the two inclined surfaces 4 fit together, thereby completely closing the clamping space, providing stable and reliable clamping for the pipeline, so that the pipeline can operate stably in complex environments.
[0040] As an optional embodiment, the rubber gasket 5 extends onto the inclined surface 4 .
[0041] Furthermore, the inclined surface 4 has a stepped structure, which includes a small inner diameter section 42 and a large inner diameter section 41 connected in sequence from the outside to the inside, and the positioning groove 11 is set through the clamping assembly 1 so that the rubber gasket 5 extends to the large inner diameter section 41, and the outer wall surface of the rubber gasket 5 is flush with the outer wall surface of the small inner diameter section 42, so that the rubber gasket 5 can at least partially cover and fit tightly on the stepped structure of the inclined surface 4, providing a more comprehensive and effective sealing and buffering effect.
[0042] As an optional embodiment, a weight-reducing groove 7 is provided on the clamp body.
[0043] Furthermore, a weight-reducing groove 7 is provided at the connection between the first wing plate 2 and the second wing plate 3 and the clamping assembly 1 to reduce weight.
[0044] The number, specifications and positions of the weight-reducing grooves 7 can be designed according to the requirements of use, as long as they are arranged without affecting their structural strength and functionality, and the weight can be reduced while maintaining sufficient strength.
[0045] As an optional embodiment, there are multiple friction protrusions 52, which extend along the circumference of the clamping space and are arranged parallel to each other.
[0046] The multiple friction protrusions 52 can increase the contact points with the pipeline, thereby dispersing the pressure and protecting the pipeline from damage.
[0047] The friction protrusions 52 extend along the circumference of the clamping space, so that the clamp body can apply pressure evenly when tightening the pipeline, thereby preventing the pipeline from being deformed in the clamping space.
[0048] As an optional embodiment, at least the outer edges of the two long sides of the rubber gasket 5 are respectively provided with friction protrusions 52 .
[0049] This arrangement allows the rubber gasket 5 to generate greater friction with the pipe surface through the friction protrusions 52 when squeezed, thereby enhancing the fastening effect and reducing friction and collision between the pipe and the edge of the clamp body during installation.
[0050] As an optional implementation method, the rubber gasket 5 is made of silicone rubber, which has the advantages of insulation, heat insulation, wear resistance and heat insulation. The clamp body is made of 7075 aluminum, which has the advantages of good structural strength, long life and light weight, and complies with aviation design principles.
[0051] The specific specifications of the clamp body and the rubber gasket 5 can be set according to the use requirements to meet the tightening requirements of the specified pipeline.
