Description

A kind of fast self-locking latch structure

Technical field

The utility model relates to a kind of latch structure, is specifically related to a kind of fast self-locking latch structure.

Background technology

At present, latch syndeton is a kind of connected mode being widely used, and it is generally by the object hinged joint of two mutual interlocks of needs together that latch connects. And latch structure is divided into two kinds of common latch and Bolt with latching action, and Bolt with latching action is because it has the auto-lock function after connection, there is larger use amount, but current Bolt with latching action ubiquity complex structure, processing cost is high, and operation is many, the problems such as complex operation, and intensity is not high, in use easily bend or rupture, impact is normally used.

Utility model content

The utility model aims to provide a kind of fast self-locking latch structure, solving the existing complex structure of traditional Bolt with latching action, complex operation, processing cost is high, intensity is low, easily bends or the problem such as fracture.

The utility model is achieved by following technical solution:

A kind of fast self-locking latch structure, comprise hinged seat and be placed in its inner workpiece, on hinged seat and workpiece, have corresponding through hole, in through hole, be fitted with latch assembly, this latch assembly comprises the latch body of direct rod shape, latch body right-hand member is provided with disk, and disk middle part is provided with the handle coaxially arranged with latch body.

Described hinged seat outer wall is connected with Z-shaped baffle plate by screw, and baffle plate vertically arranges, described disk bottom is platform by Milling Process.

Described handle end is bent into crank, and bending angle is 60-75 °.

Described latch assembly inserts in through hole and while keeping handle upward the platform on disk lower than baffle plate bottom.

Described handle and baffle plate end all have key chain hole.

The beneficial effects of the utility model are:

Compared with prior art, the fast self-locking latch structure that the utility model provides, realize the fast rotational locking of latch assembly by the handle of bending, and realize spacing to latch assembly by baffle plate and disk, avoid it to come off, compared to traditional Bolt with latching action, the utlity model has simple in structure, easy to operate, the advantage such as processing cost is low, long service life and good economy performance.

Brief description of the drawings

Fig. 1 is front view of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3-Fig. 4 is use state diagram of the present utility model;

In figure: 1-latch assembly, 2-hinged seat, 3-workpiece, 4-screw, 5-baffle plate, 6-key chain hole, 11-handle, 12-latch body, 13-disk, 14-latch body.

Detailed description of the invention

Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in desired protection domain is not limited to;

As Figure 1-3, the fast self-locking latch structure that the utility model provides, comprise hinged seat 2 and be placed in its inner workpiece 3, on hinged seat 2 and workpiece 3, have corresponding through hole, in through hole, be fitted with latch assembly 1, this latch assembly 1 comprises the latch body 12 of direct rod shape, and latch body 12 right-hand members are provided with disk 13, and disk 13 middle parts are provided with the handle 11 coaxially arranged with latch body 12. Described hinged seat 2 outer walls are connected with Z-shaped baffle plate 5 by screw 4, and baffle plate 5 vertically arranges, described disk 13 bottoms are platform by Milling Process. Described handle 11 ends are bent into crank, and bending angle is 60-75 °. Platform when described latch assembly 1 inserts in through hole and keeps handle upward on disk 13 is lower than baffle plate 5 bottoms. Described handle 11 and baffle plate 5 ends all have key chain hole 6. When use, be divided into release and locking two states, released state as shown in Figure 3, keep handle 11 to insert in the through hole on hinged seat 2 and workpiece 3 upward latch assembly 1, realize both hinged, now the podium level on disk 13, lower than baffle plate 5 ends, can be extracted latch assembly 1 arbitrarily. Need to lock time, rotary handle 11 makes its end down, and as shown in Figure 4, now the circular arc portion on disk 13 tops is placed between hinged seat 2 outer walls and baffle plate 5, and due to handle 11 gravity, baffle plate 5 has limited extracting of disk 13, can realize self-locking.
