Description
Technical field
The utility model relates to mechanical manufacturing field, particularly relate to a kind of can the anti-lost observation door of quickly opening and closing.
Background technology
Plant equipment is provided with observation door usually, facilitates current check, one block of plate is normally pressed on main body with bolt by the structure of observing door, when checking that main frame needs to open observation door, bolts all on observation door are backed out by usual needs, can open observation door, extremely inconvenience; Very easily cause the loss of observing door and set bolt simultaneously, be difficult to realize folding easily when observing door and being heavier.
Summary of the invention
The utility model for overcoming the deficiencies in the prior art, and provide a kind of can the anti-lost observation door of quickly opening and closing.
The utility model provide a kind of can the anti-lost observation door of quickly opening and closing, comprise door closure, door closure side is provided with the first bolt hole, the first bolt is provided with in first bolt hole, door closure opposite side is provided with the second bolt hole, upper end or the lower end of the second bolt hole are provided with chute, and chute is communicated with the second bolt hole, are provided with the second bolt in the second bolt hole.
Door closure is provided with handle.
First bolt and the second bolt are interior wince hook bolt.
Beneficial effect:
1, the utility model structure is simple, easy to use, by tightening and unclamping first, second bolt and simply rotate and can close and open observation door, avoids the complex operations of alignment bolt hole; Simultaneously owing to being entirely removed without any part, thus avoid the loss at zero point.
2, door closure is provided with handle, and during rotational view door, hand-holdable handle rotates, and is easy to use comfortable.

Fig. 1 is that the utility model is a kind of can structural representation in the anti-lost observation door embodiment 1 of quickly opening and closing under closure state;
Fig. 2 is that the utility model is a kind of can structural representation in the anti-lost observation door embodiment 1 of quickly opening and closing under opening;
Fig. 3 is that the utility model is a kind of can structural representation in the anti-lost observation door embodiment 2 of quickly opening and closing under closure state;
Fig. 4 is that the utility model is a kind of can structural representation in the anti-lost observation door embodiment 2 of quickly opening and closing under opening.
Detailed description of the invention
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of can the anti-lost observation door of quickly opening and closing, comprise door closure 1, door closure 1 side is provided with the first bolt hole 2, be provided with the first bolt 3 in first bolt hole 2, door closure 1 opposite side is provided with the upper end of the second bolt hole 4, second bolt hole 4 or lower end is provided with chute 5, chute 5 is communicated with the second bolt hole 4, is provided with the second bolt 6 in the second bolt hole 4.
First bolt 3 and the second bolt 6 are interior wince hook bolt.
Time fixing, door closure 1 to be fixed on by the bottom surface of the first bolt hole 2, second bolt hole 4 and side and to observe on door by the first bolt 3, second bolt 6, ensure that fastening reliability.
When observing door switch, by unclamping the first bolt 3, second bolt 6, make the second bolt 6 depart from the second bolt hole 4, now door closure 1 can rotate freely around the first bolt 3, and the second bolt 6 slides in chute 5, and door closure 1 can be opened; Owing to being rotating operation, thus simple to operate, avoid the complex operations of alignment bolt hole.Simultaneously owing to being entirely removed without any part, thus avoid the loss of part.
Embodiment 2: as shown in Figure 3, Figure 4, a kind of can the anti-lost observation door of quickly opening and closing, comprise door closure 1, door closure 1 side is provided with the first bolt hole 2, be provided with the first bolt 3 in first bolt hole 2, door closure 1 opposite side is provided with the upper end of the second bolt hole 4, second bolt hole 4 or lower end is provided with chute 5, chute 5 is communicated with the second bolt hole 4, is provided with the second bolt 6 in the second bolt hole 4.
Door closure 1 is provided with handle 7.
First bolt 3 and the second bolt 6 are interior wince hook bolt.
Time fixing, door closure 1 to be fixed on by the bottom surface of the first bolt hole 2, second bolt hole 4 and side and to observe on door by the first bolt 3, second bolt 6, ensure that fastening reliability.
When observing door switch, by unclamping the first bolt 3, second bolt 6, make the second bolt 6 depart from the second bolt hole 4, now hold handle 7 and door closure 1 is rotated freely around the first bolt 3, the second bolt 6 slides in chute 5, and door closure 1 can be opened; Owing to being rotating operation, thus simple to operate, avoid the complex operations of alignment bolt hole.Simultaneously owing to being entirely removed without any part, thus avoid the loss at zero point.
