Detailed Description
The above-described aspects are further described below in conjunction with specific embodiments. It should be understood that these examples are illustrative of the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples may be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are generally those in routine experiments.
Embodiment one:
fig. 1 shows a specific embodiment of the locking buckle arrangement according to the application, which, like some conventional buckle arrangements, also comprises a male die 1, a female die 2 and a buckle 3, the male die 1 and the female die 2 being locked to each other by means of the buckle 3.
The key improvement of this embodiment is that the male mold 1, the female mold 2 and the buckle 3 adopt a very smart structure, which is as follows:
the first side of the male die 1 (i.e. the side facing the reader in fig. 1) is fixedly provided with two protrusions 11 extending outwards in the X-direction and spaced apart in the Y-direction, the end of the protrusions 11 facing away from the first side (i.e. the end facing away from the protrusions in the Y-direction) extending upwards in the Z-direction to form lugs 11a, whereby a groove 12 is formed between the lugs 11a and the first side.
The second side of the master mold 2 (i.e., the side facing the reader in fig. 1) is formed with a groove 21 recessed inward in the X-direction, the groove 21 has an open end at a position of a third side of the master mold 2 (i.e., the horizontal surface of the master mold in fig. 1), the aforementioned third side of the master mold 2 is formed with an inwardly extending slot 22, and a partition 23 is formed on the master mold 2 between the slot 22 and the groove 21, and the partition 23 is provided with: two insertion holes 24 respectively matched with the two protruding blocks 11 (comprising the lugs 11a on the protruding blocks) and a limit clamping groove 25 positioned between the two insertion holes.
The clasp 3 comprises a clasp body 36, and a tongue 31 and a peg 32 extending downwardly in the Z direction from the bottom of the clasp body. The insert tongue 31 and the insert plate 32 are arranged at intervals in the X direction so that a partition plate caulking groove adapted to the partition plate 23 is formed therebetween. The side of the insert plate 32 facing the insert tongue 31 is provided with a beveled protrusion 33 adapted to the limit slot 25.
After the assembly, the first side of the male mold 1 is placed against the second side of the female mold 2, the protruding block 11 and the lug 11a on the protruding block are inserted into the insertion hole 24, the insertion tongue 31 is inserted into the groove 21 and the groove 12, the insertion plate 32 is inserted into the insertion slot 22, the oblique protrusion 33 is clamped into the limit clamping groove 25, and the partition 23 is inserted into the partition embedding groove. So that the clamping connection of the male die 1, the female die 2 and the buckle 3 is realized.
During assembly, the male die 1 and the female die 2 are aligned by utilizing the convex blocks 11 and the insertion holes 24, then the insertion tongues 31 and the insertion plates 32 of the buckles 3 are aligned with the open ends of the upper parts of the grooves 21 and the insertion grooves 22 in a distributed manner and are inserted downwards, and after the buckles 3 are inserted in place, the insertion tongues 31 are just inserted into the grooves 12, and the oblique protrusions 33 on the insertion plates 32 are clamped into the limit clamping grooves 25.
In order to enhance the bonding 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 are both Y-Z planes, and planes parallel to the planes of the X axis and the Z axis.
And the third side of the master mold 2 is an X-Y plane perpendicular to the second plane.
Further, the buckle 3 further includes two guide strips 34 extending downward along the Z direction, the two guide strips 34 are arranged at two opposite sides of the plugboard 32 in the Y direction at intervals, and the two guide strips 34 are inserted into the slot 22 and respectively abutted against the left and right side walls of the slot 22 in the Y direction. During assembly, the two guide strips 34 are distributed and aligned with the two side walls of the slot 22, after the buckle 3 is inserted downwards, the two guide strips 34 are respectively tightly abutted against the left side wall and the right side wall of the slot 22 to prevent the buckle 3 from shaking left and right. It can be seen that the two guide strips 34 have not only the function of guiding the insertion direction of the buckle 3, but also the function of enhancing the connection stability of the male mold, the female mold and the buckle 3.
The slot 22 is a rectangular slot. The recess 21 has the form of an isosceles trapezoid, and the two tongues 31 have side edges which are arranged to abut against the two waist edges of the trapezoid.
In order to facilitate the user to hold the buckle 3 to insert or extract the buckle 3, a hand support 35 is further fixedly disposed on the top of the buckle body 36 in this embodiment. When the user applies a sufficient force to pull up the buckle 3, the oblique protrusion 33 on the plugboard 32 is separated from the limit clamping groove 25, so that the buckle 3 can be pulled out.
A plurality of reinforcing ribs 37 are further connected between the hand rest 35 and the buckle body 36, so as to avoid the hand drag breakage caused by excessive force.
The male die, the convex blocks and the convex lugs are integrated plastic pieces, the female die and the partition plate are integrated plastic pieces, and the buckle body, the inserting tongue, the inserting plate and the oblique convex lugs are integrated plastic pieces. All three have certain plastic deformation capability.
Obviously, the two lugs 11a may be integrally connected.
Embodiment two:
fig. 8 and 9 illustrate a specific embodiment of such an I/O module system of the present application, which, like conventional I/O module systems, also includes a plurality of I/O sub-modules arranged in parallel.
The key improvement of this embodiment is that any two adjacent I/O sub-modules are interconnected by implementing such a locking snap arrangement. 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 foregoing embodiments are merely illustrative of the technical concept and features of the present application, and are not intended to limit the scope of the application in any way. All equivalent changes or modifications made according to the spirit of the main technical proposal of the application should be covered in the protection scope of the application.
