Technical Field

[0001] The utility model relates to a pipe clamp for aircraft hydraulic pipelines, belonging to the technical field of pipe clamp equipment. Background Art

[0002] At present, the hydraulic system pipelines on civil aircraft are generally clamped by pipe clamps, and then the pipe clamps are fixed on the bracket. Although this structure has a certain rigidity, the rubber material is prone to aging and wear, and the bolts for fixing the pipe clamps are relatively long, which requires a high installation space and brings certain restrictions to the installation design.

[0003] Chinese patent number: CN205001666U, mentions a civil aircraft hydraulic multi-pipe clamp, which inserts the pipe into the gap between the upper and lower clamp blocks, which not only reduces costs, but also facilitates operation and improves work efficiency. However, since the installation position of the cover plate of this type of pipe clamp is fixed, it cannot be adjusted according to the actual direction of the pipes in different directions. Now there is an urgent need for an aircraft hydraulic pipe clamp to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an aircraft hydraulic pipeline clamp to solve the problems raised in the above-mentioned background technology. The utility model has a reasonable structure and good practicality.

[0006] Furthermore, the metal mounting bottom plate is mounted and fixed to the metal bent top plate and the aircraft body mounting plate by means of mounting bolts.

[0007] Furthermore, the lower ends of the two pipe clamp limit blocks are respectively fixed to two metal rotating rods.

[0008] Furthermore, concave grooves are provided on the left and right sides of the upper inner end of the metal bent top plate.

[0009] Furthermore, the upper ends of the two high-strength threaded rods are screwed into the two threaded adjustment grooves respectively.

[0010] Furthermore, the two semicircular arc surfaces of the abutment blocks are slidably located in the two concave grooves respectively.

[0011] The beneficial effects of the utility model: the utility model is an aircraft hydraulic pipeline clamp, because the utility model adds a miniature bearing seat, a metal rotating rod, a pipe clamp limit block, a rubber pipe clamp, an elastic rubber sheet, a semicircular stop block, a high-strength threaded rod and a miniature welding nut, our design improvement and actual use have shown that the device has good practicality, can install pipelines of adapted specifications, and can adjust the installation at a certain angle according to the direction of the adapted pipeline, thereby making the device more suitable for installation and use of actual pipelines on site, and is conducive to promotion.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3The utility model provides a technical solution: an aircraft hydraulic pipeline clamp, comprising a metal mounting base plate 2, a metal bending top plate 3, a pipe clamp limit block 8, a micro bearing seat 6 and a high-strength threaded rod 15, the metal mounting base plate 2 is fitted with the lower end of the metal bending top plate 3, the upper left and right sides of the metal mounting base plate 2 are provided with bearing grooves 5, two micro bearing seats 6 are provided, the two micro bearing seats 6 are respectively installed in the two bearing grooves 5, the inner rings of the two micro bearing seats 6 are longitudinally fixed with metal rotating rods 7, the pipe clamp limit blocks 8 are provided with two, the inner sides of the two pipe clamp limit blocks 8 are penetrated A rubber pipe clamp 9 is fixed through it, and rubber grooves 10 are provided on the upper ends of the two pipe clamp limit blocks 8. Elastic rubber sheets 12 are installed in the two rubber grooves 10 through epoxy resin glue, and semicircular abutment blocks 13 are fixed on the upper ends of the two elastic rubber sheets 12. Threaded adjustment grooves 14 are provided on the left sides of the lower ends of the two pipe clamp limit blocks 8. Two high-strength threaded rods 15 are provided, and micro-welding nuts 16 are welded on the annular sides of the two high-strength threaded rods 15. This design solves the problem that the pipe clamp of the original device cannot be angled according to the actual orientation of pipelines in different orientations due to the fixed installation position of the cover plate.

[0019] As the first embodiment of the utility model: the metal mounting base plate 2 is installed and fixed to the metal bending top plate 3 and the aircraft body mounting plate 1 by means of mounting bolts 4, and the lower ends of the two pipe clamp limit blocks 8 are respectively fixed to the two metal rotating rods 7, and by adding two metal rotating rods 7 and a miniature bearing seat 6, the two pipe clamp limit blocks 8 can be adjusted to a certain angle, thereby allowing the two pipe clamp limit blocks 8 to be adjusted in angle accordingly.

[0020] Concave grooves 11 are provided on the left and right sides of the upper end of the metal bending top plate 3. The concave grooves 11 are convenient for the installation of two semicircular abutments 13. The arc surfaces of the two semicircular abutments 13 slide in the two concave grooves 11 respectively. By adding the two semicircular abutments 13, when the two pipe clamp limit blocks 8 are adjusted in angle, they are rotated in the two concave grooves 11. The upper ends of the two high-strength threaded rods 15 are respectively screwed into the two thread adjustment grooves 14. By twisting the two high-strength threaded rods 15 and the two micro-welding nuts 16, when the two pipe clamp limit blocks 8 are adjusted in angle, they can abut against the metal mounting base plate 2, thereby preventing the two pipe clamp limit blocks 8 from swinging by themselves.

[0021] As a second embodiment of the utility model: when it is necessary to adjust the angle of the two rubber tube clamps 9 according to the external pipeline angle, the two tube clamp limit blocks 8 are directly swung to adjust the angle of the two rubber tube clamps 9. During this process, the two metal rotating rods 7 are mobilized to rotate, thereby causing the inner rings of the two miniature bearing seats 6 to rotate, and the two semicircular abutment blocks 13 will also swing in the two concave grooves 11. After the adjustment is completed, use an external wrench to tighten the two miniature welding nuts 16, so that the two high-strength threaded rods 15 can be driven to rotate downward in the two threaded adjustment grooves 14 until the lower ends of the two high-strength threaded rods 15 are tightly pressed against the metal mounting base plate 2, so that the two tube clamp limit blocks 8 will not swing by themselves.

[0022] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
