Abstract
The utility model discloses a lock catch used on an observation window, and relates to a lock. The lock catch comprises a bolt, wherein a three-quarter circular ring gasket is arranged under a nut of the bolt, the three-quarter circular ring gasket is internally provided with a circular ring gasket, the thickness of the circular ring gasket is smaller than that of the three-quarter circular ring gasket, the circular ring gasket is welded with a long iron plate, and the long iron plate rotates back and forth in the position of a notch of the three-quarter circular ring gasket. The lock catch disclosed by the utility model has the beneficial effects that when a screw is inserted and tightly screwed on the observation window, the three-quarter circular ring gasket is tightly pressed on the observation window, the functions of locking and unlocking can be realized by pulling the long iron plate to rotate in the three-quarter circular ring gasket, the structure is stable and simple, the use is convenient, the design is reasonable, the long iron plate is controlled within a certain range by the three-quarter circular ring gasket, and the long iron plate can be conveniently and quickly pulled up or pulled down.
Description
Technical field:
The utility model relates to a kind of lockset, is specifically related to a kind of for the snap close on observation port.
Background technology:
The snap close being generally used on observation port requires simply, convenient unlatching, be convenient to observe constantly, existing for the snap close on observation port be generally rope with hook be connected, too simple, structure is 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.
Utility model content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, provides simple in structure, snap close that can high-speed switch window.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of for the snap close on observation port, it is characterized in that: comprise bolt, the nut below of bolt is provided with 3/4 annulus pad, in 3/4 annulus pad, be provided with an annulus pad, the thickness of annulus pad is less than the thickness of 3/4 annulus pad, a microscler iron plate of annulus pad welding, 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, has avoided microscler iron plate automatic shift.
On described microscler iron plate, be welded with the iron plate perpendicular to microscler iron plate, pull iron plate to carry out more easily switch.
Described iron plate and microscler iron plate junction are provided with floor, increase structural strength, avoid the iron plate and the fracture of microscler iron plate pad that pull iron plate to cause.
The utility model beneficial effect is: screw is inserted in to 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, simple in structure, reasonable in design, 3/4 annulus pad is controlled microscler iron plate within the specific limits, fast and easy pull-up or leave behind.
Accompanying drawing explanation:
Fig. 1 is structure side view of the present utility model;
Fig. 2 is structure upward view of the present utility model;
Wherein: 1: bolt; 2:3/4 annulus pad; 3: magnet; 4: annulus pad; 5: microscler iron plate; 6: iron plate; 7: floor.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As depicted in figs. 1 and 2 a kind of for the snap close on observation port, comprise bolt 1, the nut below of bolt 1 is provided with 3/4 annulus pad 2,3/4 annulus pad 2 two ends breach are built-in with magnet 3, in 3/4 annulus pad 2, be provided with an annulus pad 4, the thickness of annulus pad 4 is less than the thickness of 3/4 annulus pad 2, a microscler iron plate 5 of annulus pad 4 welding, microscler iron plate 5 carrys out back rotation in 3/4 annulus pad 2 indentation, there, on microscler iron plate 5, be welded with the iron plate 6 perpendicular to microscler iron plate 5, iron plate 6 is provided with floor 7 with microscler iron plate 5 junctions
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
