Specific embodiment
Embodiment one
As shown in Fig. 2 is to 9, a kind of corner protector 200 of shield duct piece that this utility model embodiment one discloses, it is by two pieces of sides
Face is pasted 201 sides and two pieces of end face welts 202 and is formed, wherein two pieces side welts 201 be connected and two pieces of side welts 201 between
At an angle, two pieces of end face welts 202 are connected to the two ends of two pieces of side welts 201, two pieces of side 201 welts and two
Block end face welt 202 surrounds a guard space jointly；Described two pieces of side welts 201 and two pieces of end face welts 202 are by rubber
Glue material is made, and integrated injection molding.
In the present embodiment, two pieces of side welts 201 are rectangle, and two pieces of end face welts 202 are triangle, in order to increase laminating
In the area in shield duct piece 100 upper and lower ends face, end face welt 202 can also be square.The length of described side welt 201 is little
In the thickness of shield duct piece 100, because rubber has elastomeric feature；In order to allow corner protector 200 have elasticity and protection intensity concurrently,
The thickness of corner protector is changed by design, damage prevention when that is, thick part need to protect shield duct piece 100 corner impact, thin-walled portion
Suitable pulling force need to be met, product can conveniently be installed and touch section of jurisdiction 100 again, specifically, the thickness of side welt 201 by
Centre increases to two ends staged, and the inner side at side welt 201 two ends forms some levels continuous ledge structure 201a, its
In, also utilize the architectural characteristic of shield duct piece 100, the ledge structure 201a of design can share the excessive of corner protector 200 two ends
Draw, it is to avoid side welt two ends are subject to Dipeptiven big and landing, thus corner protector will not landing from section of jurisdiction easily, certainly due to end face
The position of welt 202 is also closer to the top of the horn with shield duct piece 100, and, the thickness of end face welt 202 is not less than side welt
201 maximum gauge, so longer side welt 201 stretches, and end face welt 202 is close to up and down the two of shield duct piece 100
End, is that corner protector 200 can hold shield duct piece 100 tightly.
In order to strengthen grabbing and power of end face welt 202, form anti-skid structure 202a in end face welt 202 inner side；This enforcement
In example, anti-skid structure 201a is the elongated rib being covered with end face welt.
In order to coordinate the architectural characteristic of shield duct piece 100 further, side welt 201 inner side is formed and section of jurisdiction projection seat 102
The draw-in groove 201b of cooperation, forms the boss 201c with section of jurisdiction groove 101 cooperation, the stressing conditions at corner protector two ends inside the welt of side
Significantly improved, be easier to block shield duct piece 100 and difficult for drop-off when installing corner protector 200.
As shown in figure 9, when this utility model is installed with shield duct piece 100, corner protector 200 is buckled into the corner of shield duct piece,
The top of the horn of shield duct piece 200 is made to insert in guard space, wherein end face welt 202 is attached to section of jurisdiction upper and lower surface, side welt 201
It is attached to the side of section of jurisdiction, there are multiple angles the corner of section of jurisdiction, such as 80 °, 90 ° or 100 °, section of jurisdiction of the present utility model corner protector 200 is right
Corner protector in this several angle all can be installed.

As shown in FIG. 10 and 11, this utility model embodiment two disclose a kind of shield duct piece corner protector 200, its structure with
Embodiment one is substantially the same, and difference is: the anti-skid structure 202a that the present embodiment end face welt 202 inner side is formed is interval
It is distributed in the short rib inside end face welt.
Embodiment three
As shown in Figures 12 and 13, this utility model embodiment two disclose a kind of shield duct piece corner protector 200, its structure with
Embodiment one is substantially the same, and difference is: the outside of the end face welt 201 of triangle is the arc-shaped side of evagination, to increase
Fitting area.
Example IV
As shown in figure 14, corner protector 200, its structure and the enforcement of a kind of shield duct piece that this utility model embodiment two discloses
Example one is substantially the same, and difference is: the two ends of described side welt 201 are prominent with respect to middle, makes the outer of side welt
Along formation arcuate groove 201d.
Embodiment five
As shown in figs, this utility model embodiment two disclose a kind of shield duct piece corner protector 200, its structure with
Embodiment one is substantially the same, and difference is: the thickness of end face welt 202 is linearly increasing to two ends from centre, so that end face is pasted
Side 202 inner side intermediate formation special-shaped slot 202b, to increase the rear end of end face welt 202 both sides, thus increasing its intensity, additionally,
The draw-in groove 201b that side welt 201 inner side is formed is formed by hollow out, thus reducing materials, cost-effective.
These are only specific embodiment of the utility model, not the restriction to protection domain of the present utility model.All according to
