Abstract
A kind of snap close on observation port, relate to a kind of lockset, comprise bolt, 3/4 annulus pad is provided with below the nut of bolt, an annulus pad is provided with in 3/4 annulus pad, the thickness of annulus pad is less than the thickness of 3/4 annulus pad, and annulus pad welds a microscler iron plate, and microscler iron plate carrys out back rotation in 3/4 annulus pad indentation, there.Beneficial effect of the present invention is: screw is inserted in the upper of observation port, tighten, be that 3/4 annulus pad is tightly pressed on observation port, cross and pull iron plate to rotate in 3/4 annulus pad, play the effect of pinning and opening, Stability Analysis of Structures, easy to use, structure is simple, reasonable in design, microscler iron plate controls within the specific limits by 3/4 annulus pad, fast and easy pull-up or leave behind.
Description
Technical field:
The present invention relates to a kind of lockset, be specifically related to a kind of snap close on observation port.
Background technology:
The snap close be generally used on observation port requires simply, convenient unlatching, be convenient to observe constantly, existing snap close on observation port is generally rope and is connected with hook, and too simply, structure built on the sand, when equipment is shaken, rope may occur that nature departs from hook, causes observation port to be opened voluntarily, affects the carrying out of work.
Summary of the invention:
Technical problem to be solved by this invention is the defect overcoming prior art, provides structure simple, can the snap close of high-speed switch window.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of snap close on observation port, it is characterized in that: comprise bolt, 3/4 annulus pad is provided with below the nut of bolt, an annulus pad is provided with in 3/4 annulus pad, the thickness of annulus pad is less than the thickness of 3/4 annulus pad, annulus pad welds a microscler iron plate, and microscler iron plate carrys out back rotation in 3/4 annulus pad indentation, there.
3/4 described annulus pad two ends breach is built-in with magnet, and microscler iron plate goes to any one end of two ends breach and all can be held by magnet, strengthens stability, avoids microscler iron plate automatic shift.
Described microscler iron plate is welded with the iron plate perpendicular to microscler iron plate, pulls iron plate to carry out switch more easily.
Described iron plate and microscler iron plate junction are provided with floor, increase structural strength, and the iron plate avoiding pulling iron plate to cause and microscler iron plate pad rupture.
Beneficial effect of the present invention is: screw is inserted in the upper of observation port, tighten, be that 3/4 annulus pad is tightly pressed on observation port, cross and pull iron plate to rotate in 3/4 annulus pad, play the effect of pinning and opening, Stability Analysis of Structures, easy to use, structure is simple, reasonable in design, microscler iron plate controls within the specific limits by 3/4 annulus pad, fast and easy pull-up or leave behind.
Accompanying drawing illustrates:
Fig. 1 is structure side view of the present invention;
Fig. 2 is structure upward view of the present invention;
Wherein: 1: bolt; 2:3/4 annulus pad; 3: magnet; 4: annulus pad; 5: microscler iron plate; 6: iron plate; 7: floor.
Detailed description of the invention:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
A kind of snap close on observation port as depicted in figs. 1 and 2, comprise bolt 1,3/4 annulus pad 2 is provided with below the nut of bolt 1,3/4 annulus pad 2 two ends breach is built-in with magnet 3, an annulus pad 4 is provided with in 3/4 annulus pad 2, the thickness of annulus pad 4 is less than the thickness of 3/4 annulus pad 2, annulus pad 4 welds a microscler iron plate 5, microscler iron plate 5 carrys out back rotation in 3/4 annulus pad 2 indentation, there, microscler iron plate 5 is welded with the iron plate 6 perpendicular to microscler iron plate 7, iron plate 6 and microscler iron plate 5 junction are provided with floor 7
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
