The utility model discloses solve the hose among the prior art and warp the extrusion pencil, make the pencil unable removal, cause the pencil wearing and tearing or the solder joint drops, produce very big hidden danger technical problem to the safety of car, provide the hose.

In order to solve the technical problem, the technical scheme of the utility model is specifically as follows:

a hose, comprising: the hose is internally used for inserting wire harnesses;

the framework is arranged inside the pipe wall of the rubber pipe and is used for supporting the rubber pipe and preventing the rubber pipe from deforming;

wherein, the skeleton has a plurality of steel rings of open-ended C type structure for one end.

Furthermore, the steel rings are sequentially arranged along the length direction of the rubber pipe at a certain interval, and the direction of the openings is the same.

Furthermore, a soft connecting piece is arranged between the adjacent steel rings, two ends of the soft connecting piece are respectively connected with the adjacent steel rings, and the soft connecting piece is arranged inside the pipe wall of the rubber pipe.

Furthermore, the cross section of the soft connecting piece is of an arc-shaped structure, and the radius of the soft connecting piece is the same as that of the steel ring.

The utility model discloses following beneficial effect has:

the utility model discloses a hose, through setting up the steel ring of C type structure, can provide the support to the rubber tube, prevent that the inside pencil of rubber tube from being extruded by outside pencil, and simultaneously, the inside pencil of rubber tube can also have certain activity, prevents the crust wearing and tearing of pencil, also can prevent the welding point of pencil from desoldering, and through setting up the flexible connector, the flexible connector is except can providing certain holding power to the rubber tube, still does not influence the bending of rubber tube, can make the better adaptation installation environment of rubber tube.

The reference numerals in the figures denote:

1. a hose; 2. steel rings; 3. a flexible connector; 4. a wire harness.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a hose includes: the rubber tube 1 is internally provided with a wire harness 4;

the framework is arranged inside the pipe wall of the rubber pipe 1 and is used for supporting the rubber pipe 1 and preventing the rubber pipe 1 from deforming;

wherein, the skeleton has a plurality of steel rings 2 of open-ended C type structure for one end.

The working principle is as follows: during installation, the wire harness 4 penetrates into the rubber tube 1, then the wire harness 4 is installed at a required position, the wire harness 4 can freely move in the rubber tube 1 for a certain distance, and the certain distance is determined according to the operation requirement, so that the wire harness 4 can have a certain movement allowance; the steel ring 2 with the C-shaped structure is arranged, the steel ring 2 can effectively support the rubber tube 1, the rubber tube 1 is prevented from being extruded and deformed, and further the movement allowance of a wire harness 4 in the rubber tube 1 is influenced, the steel ring 2 is arranged into the C-shaped structure, the steel ring 2 with the C-shaped structure can support the rubber tube 1 and does not influence the deformation of the rubber tube 1 according to the field working environment, in the prior art, a component similar to a spring is placed in the rubber tube 1 and is used for supporting the rubber tube 1, so that the rubber tube 1 is hard, is inconvenient to mount and is easy to damage the rubber tube 1; through the steel ring 2 with the C-shaped structure, the deformation of the rubber tube 1 according to the field working environment is not influenced while the rubber tube 1 is supported.

The steel rings 2 are sequentially arranged along the length direction of the rubber pipe 1 at certain intervals, and the opening directions are the same.

The theory of operation, the steel ring 2 opening orientation of C type structure is the same, mainly is in order to make the convenience, also is favorable to the bending of rubber tube 1 simultaneously, can not exert an influence to rubber tube 1.

A flexible connecting piece 3 is arranged between the adjacent steel rings 2, two ends of the flexible connecting piece 3 are respectively connected with the adjacent steel rings 2, and the flexible connecting piece 3 is arranged in the pipe wall of the rubber pipe 1.

The working principle is as follows: the soft connecting piece 3 can increase the internal supporting force of the rubber hose 1, and when the rubber hose 1 is bent, the soft connecting piece 3 can play a main supporting role on the bent part to prevent the rubber hose 1 from being extruded and deformed on the bent part.

The cross section of the soft connecting piece 3 is of an arc-shaped structure, and the radius of the soft connecting piece 3 is the same as that of the steel ring 2.

According to the working principle, the flexible connecting piece 3 is connected with the adjacent steel rings 2, the arc faces outwards, a good supporting effect can be achieved on the rubber pipe 1, meanwhile, the radius of the flexible connecting piece is the same as that of the steel rings 2, and during manufacturing, the flexible connecting piece 3 and the steel rings 2 are on the same arc surface, so that no height drop exists, no shearing force exists when the rubber pipe 1 is bent, and the rubber pipe 1 is prevented from being damaged by the inner steel rings 2 or the flexible connecting pieces 3 when the rubber pipe 1 is bent.
