Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic hoses, in particular to a hydraulic hose with internal and external tensile resistance. Background Art

[0002] Hydraulic hose is a pipe used to transmit hydraulic pressure, usually composed of an inner rubber layer, a reinforcement layer and an outer rubber layer. Under high pressure conditions, hydraulic hoses need to have good tensile strength to ensure that they will not break or leak during operation. However, hydraulic hoses in the prior art still have certain defects when used and need to be improved.

[0003] When the hydraulic hose in the prior art is in use, it is often exposed to various stresses such as stretching, bending, vibration and external physical impact. These factors may cause the hose to be damaged, leak or even completely fail, which in turn leads to serious safety accidents. It is easy to break and cannot withstand high tension, which leads to a decrease in its tensile strength. This not only affects the normal operation of the hydraulic system, but also may cause safety hazards. Therefore, a hydraulic hose with internal and external tensile resistance is proposed to overcome the above-mentioned defects. Utility Model Content

[0004] The utility model aims to solve the defect that it is inconvenient to increase the tensile resistance in the prior art, and proposes a hydraulic hose with internal and external tensile resistance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hydraulic hose with internal and external tensile resistance comprises a hydraulic hose body. Both sides of the hydraulic hose body are provided with a plurality of positioning holes.

[0007] The first protective sleeve and the second protective sleeve, the inner circles of the first protective sleeve and the second protective sleeve are installed with a plurality of positioning pins, and the plurality of positioning pins are respectively inserted into the corresponding positioning holes, a mounting plate is installed on the top side of the first protective sleeve, a mounting groove is opened on the top side of the second protective sleeve, the mounting plate is fitted in the mounting groove, and two bolts are fitted between the second protective sleeve and the mounting plate.

[0008] One side of the first protective sleeve and the second protective sleeve is connected with a plurality of insertion rods, and the other side of the first protective sleeve and the second protective sleeve is provided with positioning grooves, and the insertion rods are inserted into the positioning grooves.

[0009] Preferably, a plurality of positioning pins are equidistantly distributed at middle positions of the first protective sleeve and the second protective sleeve.

[0010] Preferably, a plurality of insertion rods are distributed in a ring shape on one side of the first protective sleeve and the second protective sleeve.
