Detailed Description

The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for illustrative purposes and are not intended to limit the scope of the present application. The conditions used in the examples may be further adjusted according to the conditions of the particular manufacturer, and the conditions not specified are generally the conditions in routine experiments.

the first embodiment is as follows:

Fig. 1 shows a specific embodiment of the locking buckle device of the present application, and like some conventional buckle devices, the buckle device also includes a male mold 1, a female mold 2 and a buckle 3, and the male mold 1 and the female mold 2 are locked and fixed to each other by the buckle 3.

the key improvement of this embodiment lies in that above-mentioned public mould 1, female mould 2 and buckle 3 have adopted a very ingenious structure, specifically as follows:

two projections 11 extending outwards along the X direction and arranged at intervals in the Y direction are fixedly arranged on a first side surface (i.e. the surface facing the reader in fig. 1) of the male die 1, and one end of the projection 11 facing away from the first side surface (i.e. the end far away from the projection in the Y direction) extends upwards along the Z direction to form a lug 11a, so that a groove 12 is formed between the lug 11a and the first side surface.

A second side surface (i.e., the surface facing the reader in fig. 1) of the female die 2 is formed with a groove 21 recessed inward in the X direction, the groove 21 has an open end at a third side surface (i.e., the horizontal surface of the female die in fig. 1) of the female die 2, the third side surface of the female die 2 is formed with an inward extending slot 22, and the female die 2 is formed with a partition 23 between the slot 22 and the groove 21, and the partition 23 is provided with: two insertion holes 24 respectively matched with the two lugs 11 (including lugs 11a on the lugs) and a limit clamping groove 25 positioned between the two insertion holes.

The clip 3 includes a clip body 36, and a tongue 31 and an insert plate 32 extending downward from the bottom of the clip body in the Z direction. The tongue 31 and the insert plate 32 are arranged at an interval in the X direction so that a partition insertion groove adapted to the partition 23 is formed therebetween. The side of the insert plate 32 facing the insert tongue 31 is provided with an oblique projection 33 adapted to the limit slot 25.

After the assembly is completed, the first side surface of the male die 1 is arranged to be attached to the second side surface of the female die 2, the projection 11 and the lug 11a on the projection are embedded into the insertion hole 24, the insertion tongue 31 extends into the groove 21 and is inserted into the groove 12, the insertion plate 32 is inserted into the insertion groove 22, the oblique projection 33 is clamped into the limiting clamping groove 25, and the partition plate 23 is embedded into the partition plate embedding groove. So realize the chucking of public mould 1, master model 2 and buckle 3 and connect.

during assembly, the male die 1 and the female die 2 are aligned by using the convex block 11 and the inserting hole 24, then the inserting tongue 31 and the inserting plate 32 of the buckle 3 are distributed and aligned with the open end of the upper part of the groove 21 and the inserting groove 22 and are inserted downwards, after the buckle 3 is inserted in place, the inserting tongue 31 is just inserted into the groove 12, and the oblique protrusion 33 on the inserting plate 32 is clamped into the limiting clamping groove 25.

in order to enhance the fitting degree of the male mold 1 and the female mold 2, in this embodiment, the first side surface of the male mold 1 and the second side surface of the female mold 2 are both planar structures, and both are Y-Z planes, which are parallel to the planes of the X axis and the Z axis.

And the third side of the master model 2 is an X-Y plane perpendicular to its second plane.

further, the buckle 3 further includes two guide strips 34 extending downward along the Z direction, the two guide strips 34 are disposed at intervals on two opposite sides of the insert plate 32 in the Y direction, and the two guide strips 34 are inserted into the slot 22 and abut against two left and right sidewalls of the slot 22 in the Y direction, respectively. During assembly, the two guide strips 34 are firstly distributed and aligned to two side walls of the slot 22, the buckle 3 is inserted downwards, and the two guide strips 34 are tightly abutted against the left side wall and the right side wall of the slot 22 respectively after insertion to prevent the buckle 3 from shaking left and right. It can be seen that the two guide strips 34 not only have the function of guiding the inserting direction of the buckle 3, but also have the function of enhancing the connection stability of the male die, the female die and the buckle 3.

the above-mentioned slot 22 is a rectangular slot. The groove 21 is in the shape of an isosceles trapezoid, and the two insertion tongues 31 respectively have side edges which are arranged to abut against the two waist edges of the isosceles trapezoid.

in order to facilitate the user to grip the buckle 3 to complete the insertion or extraction of the buckle 3, a hand support 35 is further fixedly disposed on the top of the buckle body 36. When the user applies enough force to pull out the buckle 3, the inclined protrusion 33 of the insertion plate 32 is separated from the limit slot 25, so that the buckle 3 can be pulled out.

A plurality of reinforcing ribs 37 are further connected between the hand support 35 and the buckle body 36, so that the hand support is prevented from being broken due to excessive force.

The male die, the convex block and the convex lug are integrated into one plastic piece, the female die and the partition plate are integrated into one plastic piece, and the buckle body, the inserting tongue, the inserting plate and the oblique convex are integrated into one plastic piece. All the three have certain plastic deformation capability.

obviously, the two lugs 11a may also be connected together.

Example two:

FIGS. 8 and 9 illustrate one embodiment of an I/O module system of the present application, which, like a conventional I/O module system, also includes a plurality of I/O sub-modules arranged in parallel.

A key improvement of this embodiment is that any two adjacent I/O submodules are interconnected by implementing such a locking snap-in device. In two adjacent I/O submodules, one I/O submodule is fixedly or integrally provided with a male die, and the other I/O submodule is fixedly or integrally provided with a female die.

The above embodiments are only for illustrating the technical concepts and features of the present application, and the purpose of the embodiments is to enable people to understand the content of the present application and implement the present application, and not to limit the protection scope of the present application. All equivalent changes and modifications made according to the spirit of the main technical scheme of the application are covered in the protection scope of the application.
