Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
A kind of specific embodiment 1 of the cover board canal of the utility model, as shown in Figure 2 to Figure 3, including rectangle canal body 1 and
The cover board 2 that be located in the top of rectangle canal body 1, is wherein both provided with a dowel 4 in the opening's edge of 1 two side of canal body, cover board 2 it is interior
The dowel 4 is corresponded on side be provided with preformed hole 3, cover board 2 and canal body 1 coordinated by inserting between dowel 4 and preformed hole 3
It realizes positioning, and then prevents cover board 2 from falling off.
In said structure, 3 ~ 4 times of 4 diameter of a diameter of dowel of the preformed hole 3, which can reduce pre-
Box out 3 with required precision when 4 grafting of dowel, allow dowel 4 and preformed hole 3 be quick, smooth grafting.The preformed hole 3
Depth is not less than the length of 4 exposed parts of dowel so that 4 exposed parts of dowel can be fully inserted into preformed hole 3, avoid dowel 4
And fitting fastening of the connected structure of preformed hole 3 between cover board 2 and canal body 1 has an impact.
The diameter of the dowel 4 is not less than 20mm, so that dowel 4 is had enough intensity, avoids dowel 4 during the installation process
It is bent because being collided.The built-in length of the dowel 4 is not less than 100mm, and protruded length is not less than 50mm, is not more than
150mm, the structure make fixation between dowel 4 and canal body 1, dowel 4 be not easy to fall off from canal body 1, the exposed portion of dowel
Dividing should not be long, and the installation of cover board 2 is facilitated to fix.
The cover board canal of the utility model, the preformed hole 3 that dowel 4 is set on canal body 1 and cover board 2 and is coordinated with dowel 4,
The positioning to cover board 2 is realized by the inserting cooperation between dowel 4 and preformed hole 3, not only solves the problem of cover board 2 falls off,
Moreover, connected structure manufacturing process is simple, when making only need on 1 both sides wall port edge of canal body pre-buried dowel 4, in cover board 2
Preformed hole corresponding with the dowel is added on side, without making template, the volume and weight change of cover board 2 and canal body 1
Change is also little, and connected structure is simple and reliable, and cost is relatively low, convenient for being widely applied and using.
In addition, being arranged dowel 4 on canal body 1,4 insertion depth of deeper dowel can be set without increasing canal body 1
Volume.
