[0041] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0042] This embodiment provides a spring buckle threading device, such as Figure 1 and Figure 2 As shown, the spring buckle threading device includes a base 100, a fixed mold 200 and a movable mold 300, wherein the fixed mold 200 is arranged on the base 100; the movable mold 300 is movably arranged on the base 100, and can move relative to the fixed mold 200 to realize opening and closing of the mold; the fixed mold 200 and the movable mold 300 form a rope winding channel and a spring buckle accommodating cavity in the mold closing state, and the rope winding channel has an inlet and an outlet, and the inlet and the outlet are respectively connected with the spring buckle accommodating cavity at the spring buckle threading hole; when air flow is introduced into the inlet, the threading rope can be passed through one threading hole and passed out from another threading hole under the action of the air source.

[0043] The spring buckle threading device provided in the present embodiment realizes mold opening and closing by the movement of the movable mold 300 relative to the fixed mold 200; wherein, the fixed mold 200 and the movable mold 300 can form a rope winding channel and a spring buckle accommodating cavity in the mold closing state. Since the inlet and outlet of the rope winding channel are respectively connected with the spring buckle accommodating cavity at the spring buckle threading hole, during the specific operation, the spring buckle 10 to be threaded can be placed in the spring buckle accommodating cavity, and the spring buckle threading hole can be opened to ensure that the rope winding channel is connected with the spring buckle accommodating cavity. In the aforementioned connected state, when air flow is introduced at the inlet, the threading rope can be passed through one threading hole and out of the other threading hole under the action of the air source, thereby realizing the threading operation.

[0044] As can be seen from the foregoing, the spring buckle threading device of this embodiment can complete the threading operation by introducing airflow once. Compared with the prior art which requires multiple manual operations, the pneumatic threading method of the present invention makes the threading speed faster and the threading efficiency higher. In addition, after the threading is completed, it is also convenient to take out the spring buckle.

[0045] It should be noted that the spring buckle threading device of this embodiment adopts a pneumatic threading method, that is, relying on the suction effect generated by the airflow, the threading rope can move along the rope winding channel driven by the airflow and complete the threading operation; of course, the spring buckle threading device that meets this condition can adopt a variety of forms, and all forms are within the protection scope of the present invention.

[0046] In one embodiment of the present application, the spring hook accommodating chamber divides the rope winding channel into a semi-annular section, an entrance section and an exit section, and the entrance section and the exit section are both located on a side of the spring hook accommodating chamber away from the semi-annular section.

[0047] The inlet section and the outlet section are located on the same horizontal plane.

[0048] Specifically, Figure 3 As shown, the fixed mold 200 is provided with a fixed mold spring buckle groove 210, a fixed mold semi-annular groove 220, a fixed mold inlet groove 230 and a fixed mold outlet groove 240, wherein the fixed mold spring buckle groove 210 separates the fixed mold semi-annular groove 220 and the fixed mold inlet groove 230 and the fixed mold outlet groove 240, and the fixed mold inlet groove 230 and the fixed mold outlet groove 240 are located on the same side of the fixed mold spring buckle groove 210. Figure 4 As shown, the movable mold 300 is provided with a movable mold spring buckle groove 310, a movable mold semi-annular groove 320, a movable mold inlet groove 330 and a movable mold outlet groove 340, wherein the movable mold spring buckle groove 310 divides the movable mold semi-annular groove 320 and the movable mold inlet groove 330 and the movable mold outlet groove 340, and the movable mold inlet groove 330 and the movable mold outlet groove 340 are located on the same side of the movable mold spring buckle groove 310.

[0049] Combination Figure 3 and Figure 4The fixed mold semi-annular groove 220 and the movable mold semi-annular groove 320 in this embodiment can be approximately regarded as "U"-shaped grooves.

[0050] Among them, in the mold closing state, the fixed mold spring buckle groove 210 and the movable mold spring buckle groove 310 are buckled to form a spring buckle accommodating cavity; the fixed mold semi-annular groove 220 and the movable mold semi-annular groove 320 are buckled to form a semi-annular section; the fixed mold inlet groove 230 and the movable mold inlet groove 330 are buckled to form an inlet section; the fixed mold outlet groove 240 and the movable mold outlet groove 340 are buckled to form an outlet section.

[0051] Further, such as Figure 3 and Figure 4 As shown, the entrance section is provided with a threading channel; the threading channel includes an inclined section and a horizontal section connected to the inclined section, and the inclined section is gradually inclined downward from the outside to the inside; the threading channel is provided with a pipeline orifice 253, and the air pipe enters through the pipeline orifice 253 with the pipe opening facing the horizontal section.

[0052] Among them, the inclined section is higher than the horizontal section, and can form a height difference. Since the inlet section and the outlet section are located on the same horizontal plane, the inclined section also forms a height difference with the outlet section. According to the siphon principle, the airflow can form a larger suction force at the outlet of the trachea. Under the action of the pressure difference, the airflow will drive the threading rope to realize the threading operation.

[0053] In one embodiment of the present application, Figures 2 to 4 The fixed mold 200 is provided with a fixed mold guide nozzle 250, on which a fixed mold inclined groove section 251 and a fixed mold horizontal groove section 252 are provided. The fixed mold horizontal groove section 252 extends outward along the axial direction to form a pipeline hole (not shown in the drawings) for passing an air pipe (not shown in the drawings), and the pipeline hole is located below the fixed mold inclined groove section 251; the movable mold 300 is provided with a movable mold guide nozzle 350, on which a movable mold inclined groove section 351 matching with the fixed mold inclined groove section 251 and a movable mold horizontal groove section 352 matching with the fixed mold horizontal groove section 252 are provided.

[0054] In the mold closing state, the fixed mold inclined groove section 251 and the movable mold inclined groove section 351 are buckled to form the inclined section of the threading channel; the fixed mold horizontal groove section 252 and the movable mold horizontal groove section 352 are buckled to form the horizontal section of the threading channel.

[0055] like Figure 2 and Figure 3 As shown, the pipeline opening 253 is arranged on one side of the fixed mold guide nozzle 250, and the center line of the pipeline opening 253 is arranged at 90 degrees with the axis of the fixed mold horizontal groove section 252; wherein, the air pipe passes through the pipeline opening 253, and the pipe opening of the air pipe is facing the horizontal section.

[0056] In this embodiment, the inclination angle of the inclined section relative to the horizontal section ranges from 10 to 30°. For example, the inclination angle of the inclined section relative to the horizontal section can be 10°, 15°, 20°, 25° or 30°, etc., and such a setting can achieve the best effect.

[0057] The movable mold 300 can be movably disposed on the base 100 in various forms.

[0058] In one embodiment of the present application, the spring buckle threading device further includes a driving mechanism, which is mounted on the base 100 ; the driving mechanism is transmission-connected to the movable mold 300 , and is used to drive the movable mold 300 to move closer to or away from the fixed mold 200 .

[0059] Specifically, Figure 1 As shown, the driving mechanism includes a driving cylinder 410; the base 100 includes a bottom plate and a vertical plate 120 erected on the bottom plate, and the vertical plate 120 has a limiting cavity for accommodating the cylinder body of the driving cylinder 410; the piston rod of the driving cylinder 410 is fixedly connected to the movable mold 300.

[0060] The spring buckle threading device of this embodiment can be applied to various types of spring buckles, not limited to Figure 5 The spring buckle 10 shown can be specifically adapted to various types of spring buckles by appropriately adjusting the structure of the spring buckle accommodating cavity.

[0061] The fixed mold 200 can be detachably connected to the bottom plate 110 ; the movable mold 300 can be detachably connected to the middle piece 420 ; such a configuration can facilitate the replacement of the fixed mold 200 and the movable mold 300 .

[0062] Furthermore, the piston rod of the driving cylinder 410 is fixedly connected to the movable mold 300 through the middle piece 420; a buffer structure is provided between the middle piece 420 and the movable mold 300, which is used to buffer the movement of the movable mold 300. Such a configuration can be applicable to fixed molds 200 and movable molds 300 of different thicknesses. When the thickness of the fixed mold 200 or the movable mold 300 changes, the buffer structure can buffer the movement of the movable mold 300 to reduce the impact force between the fixed mold 200 and the movable mold 300, thereby extending the service life of the mold; in addition, without replacing the mold, the buffer structure can also play a corresponding buffering role.

[0063] Optionally, the buffer structure includes an elastic member disposed between the intermediate member 420 and the movable mold 300; wherein the elastic member may be a spring. Furthermore, a guide structure is disposed between the fixed mold 200 and the movable mold 300; one of the fixed mold 200 and the movable mold 300 is provided with a concave limiting pin, and the other is provided with a convex limiting pin used in conjunction with the concave limiting pin.

[0065] like Figure 5 As shown, the spring buckle accommodating chamber has a side opening; a guide rod cylinder 500 is provided on the base 100, and the piston rod of the guide rod cylinder 500 can be inserted into the spring buckle 10 through the side opening to open the spring buckle threading hole. Such a setting can further reduce manual participation and further improve the threading speed and efficiency.

[0066] In other embodiments, the spring hook threading hole can be opened manually using a tool.

[0067] Please continue to refer to Figure 5 A holder 600 for fixing the guide rod cylinder 500 is also provided on the bottom plate 110 to ensure that the guide rod cylinder 500 will not shift during operation.

[0068] Reference Figures 3 to 5 The specific working process of the spring buckle threading device is as follows:

[0069] Manually place the spring buckle 10 in the fixed mold spring buckle groove 210;

[0070] Start the guide rod cylinder 500, insert the piston rod of the guide rod cylinder 500 into the spring buckle 10, and open the two spring buckle threading holes on the spring buckle 10. At the same time, the driving cylinder 410 drives the movable mold 300 to move downward to complete the mold closing;

[0071] Manually feed the threading rope into the threading channel formed by the fixed mold guide nozzle 250 and the movable mold guide nozzle 350 to ensure that the rope end of the threading rope exceeds the pipe opening of the air pipe;

[0072] Start the gas source, and under the action of the gas source, the threading rope can pass through the left threading hole of the spring buckle 10, the semi-annular section, and the right threading hole of the spring buckle 10, and finally pass through the outlet section;

[0073] The driving cylinder 410 drives the movable mold 300 to move upward to complete the mold opening.

[0074] In summary, by setting up experimental examples and comparative examples, the threading efficiency is improved by 33.33% by using the spring buckle threading device of this embodiment.

[0075] This embodiment also provides a spring buckle threading method, which uses the aforementioned spring buckle threading device to thread the spring buckle 10.

[0076] The spring buckle 10 can cover all types of spring buckles on the market, preferably a spring buckle with two threading holes.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
