[0027] The utility model provides a cable protection tube structure for an engine cover. Figure 1-3 , including an outer tube 100 and a reinforcing wire component 200;

[0028] Please continue reading Figure 1-2 , as an outer tube 100 connected to the base frame, the outer tube 100 has an inner liner tube 110 built therein;

[0029] Please continue reading Figure 1-3 There are two groups of reinforcing wire components 200, which are symmetrically connected to the outer tube 100, and play a reinforcing role in fixing the entire PVC outer layer. The reinforcing wire 210 in the outer tube 100 ensures the rigidity of the outer tube 100 and the protection of the inner liner 110 to a certain extent, and the product appearance will not be deformed or warped.

[0030] The reinforcing wire component 200 includes a reinforcing wire 210 connected to the outer tube 100. The reinforcing wire 210 is made of nylon and carbon fiber and is made into an elliptical wire structure in a certain direction. The elliptical structure of the reinforcing wire 210 makes it difficult for itself to rotate, which plays a reinforcing role in fixing the entire PVC outer layer, so that the PE liner tube is well protected, thereby improving the rigidity of the entire protective tube;

[0031] Furthermore, in order to increase the tightness of the connection between the reinforcing wire 210 and the outer tube 100, a plurality of groups of connecting grooves 211 are spirally provided on the outer side of the reinforcing wire 210 from front to back, and the spacing between two adjacent connecting grooves 211 is the same. The connecting grooves 211 are provided to increase the bonding area between the reinforcing wire 210 and the outer tube, and the area is increased, thereby improving the bonding strength of the product, so that after the product is injection molded, the probability of torsion and deformation is small, and the possibility of the reinforcing wire being pulled out alone is also greatly reduced;

[0032] Furthermore, in order to increase the granularity of the surface of the reinforcing wire 210 and improve the bonding strength between the reinforcing wire 210 and the outer tube 100, the outer side of the reinforcing wire 210 is integrally connected with a plurality of groups of anti-slip protrusions 220. The plurality of groups of anti-slip protrusions 220 are linearly and equidistantly arranged from front to back along the outer side of the reinforcing wire 210 with the axis of the reinforcing wire 210 as the center of the circle. The granularity of the surface of the reinforcing wire 210 is increased by the anti-slip protrusions 220, thereby further improving the bonding strength between the reinforcing wire 210 and the outer tube 100 to ensure.

[0033] Working principle: When the utility model is in use, the reinforcing wire 210 is inside the outer tube 100, which ensures the rigidity of the outer tube 100 and the protection of the inner lining tube 110 to a certain extent, and the product appearance will not be deformed or warped. The bonding area between the reinforcing wire 210 and the outer tube is increased by setting the connecting groove 211. The increased area improves the bonding strength of the product, so that after the product is injection molded, the probability of torsion and deformation is small, and the possibility of the reinforcing wire being pulled out separately is also greatly reduced. At the same time, the anti-slip bumps 220 increase the granularity of the surface of the reinforcing wire 210, thereby further improving the bonding strength between the reinforcing wire 210 and the outer tube 100.
