Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of nuclear power plant TPL switch modified model takes lamp instrument, including metal master outside Shell 1, insulation protection post 2, adjusting handle 3, bolt 4.Inside the insertion metal master of insulation protection post 2 shell 1.Bolt 4 is worn successively 1 outer wall of metal master shell, insulation protection post 2,1 outer wall of metal master shell is crossed, by adjusting handle 3 and metal master shell 1 is fixedly connected.
As shown in Figure 1, Figure 2 and Figure 3, the generally hollow cylindrical of metal master shell 1, is divided into left and right two portions Point, for taking lamp end, right part is handheld terminal to left part.External diameter of the external diameter of 1 right part of metal master shell more than left part, the internal diameter of right part More than the internal diameter of left part, the outer surface of right part is provided with anti-skidding annular knurl, facilitates hand-held.In 1 left part of metal master shell Left end axially grooved along the horizontal plane, extend to the middle part of metal master shell 1.Before the right side of 1 groove of metal master shell Rear end face symmetrically offers two circular ports, connects with groove, and the design of the circular hole ensure that the tension force and aperture adjustment for taking lamp end. Two installing holes are symmetrically offered in the upper and lower end face of metal master shell 1, positioned at the left side of above-mentioned circular port, for installing spiral shell Bolt 4.
As depicted in figs. 1 and 2, the generally cylindrical of insulation protection post 2, external diameter are interior with 1 left part of metal master shell Footpath matches.Insulation protection post 2 in the horizontal direction installed in 1 left part of metal master shell inside, with metal master shell 1 Installing hole correspondence position vertically offers manhole, for through bolt 4.Insulation protection post 2 is used for after lamp is taken The position of bulb is limited, and bulb is played a protective role.Insulation protection post 2 has the resilience force of 1 to 1.2mm simultaneously, can protect Card metal master shell 1 under external force will not permanent deformation.
As shown in figure 4, the generally cylindrical of adjusting handle 3, center vertically offers through hole, and through-hole wall sets Female thread is equipped with, for fixing bolt 4.Adjusting handle 3 is arranged at the installing hole on the upper surface of metal master shell 1.Spiral shell Bolt 4 is sequentially passed through outside the installing hole of 1 lower end of metal master shell, the manhole of insulation protection post 2, metal master from bottom to top The through hole of the installing hole and adjusting handle 3 at 1 upper end end of shell, is fixed on metal master shell 1 by adjusting handle 3.Bolt 4 is used In the position of fixed insulation guard column 2, prevent the position of insulation protection post 2 during lamp is taken from shifting.Adjusted by rotation Section handwheel 3 can control to take aperture and the tension force that lamp instrument takes lamp end.
In the present embodiment, metal master shell 1, adjusting handle 3 and bolt 4 are made using Stainless steel 316 L materials, Insulation protection post 2 is made using low-smoke and flame retardant quality of rubber materials.
The implementation of the present invention is explained in detail above in conjunction with embodiment, but the present invention is not limited to above-mentioned reality Example is applied, in the ken that those of ordinary skill in the art possess, can be with the premise of without departing from present inventive concept Various changes can be made.The content not being described in detail in description of the invention can adopt prior art.
