[0036] As shown in Figures 1-5 The utility model relates to a connecting buckle for mounting injection molding parts, which comprises a fixed plate 100, a connecting plate 200 used in cooperation with the fixed plate 100, and a flat head bolt 300, wherein the fixed plate 100 is provided with a through hole 110, and one side of the fixed plate 100 is provided with an opening for inserting the connecting plate 200, and the opening is in communication with the through hole 110.

[0037] The flat head bolt 300 is placed in the through hole 110 from the opening, and is buckled with the fixed plate 100 through the connecting plate 200 to limit the flat head bolt 300 in the through hole 110.

[0038] The upper end surface of the connecting plate 200 is provided with a baffle 240, and the baffle 240 is located above the flat head bolt 300, and the baffle 240 has the following two states relative to the flat head bolt 300.

[0039] When the baffle 240 is located above the flat head bolt 300, the flat head bolt 300 cannot be disassembled;

[0040] When the baffle 240 is away from the upper side of the flat head bolt 300, the flat head bolt 300 can be disassembled.

[0041] It should be noted that the fixed plate 100 and the connecting plate 200 are integrally formed, and after the connecting plate 200 and the fixed plate 100 are assembled, the flat head bolt 300 can be limited in the through hole 110, and similarly, the connecting plate 200 and the fixed plate 100 can be fixed by the flat head bolt 300.

[0042] Due to the existence of the baffle 240, when the flat head bolt 300 is loose, the flat head bolt 300 can only move up and down a small distance in the through hole 110 and cannot be separated.

[0043] When the flat head bolt 300 needs to be disassembled, the position of the connecting plate 200 relative to the fixed plate 100 needs to be moved, and then the baffle 240 is moved away from the flat head bolt 300, at this time, the flat head bolt 300 can be disassembled.

[0044] The fixed plate 100 is provided with a semicircular groove 120, and the diameter of the semicircular groove 120 is greater than the diameter of the through hole 110.

[0045] The opposite sides of the opening are provided with stepped grooves 130 on the fixed plate 100, and the diameter between the two stepped grooves 130 is greater than or equal to the diameter of the semicircular groove 120, facilitating the cooperation of the connecting plate 200 and the fixed plate 100, and avoiding interference.

[0046] The stepped groove 130 has a first step 131 and a second step 132, and the upper end surface of the first step 131 is higher than the upper end surface of the second step 132, and the upper end surface of the first step 131 is at the same level as the ground of the semicircular groove 120.

[0047] The first step 131 and the second step 132 are used together to position and connect the connecting plate 200 and the fixed plate 100.

[0048] The second step 132 is located between the first step 131 and the semicircular groove 120.

[0049] Further, the connecting plate 200 is composed of a panel 210 and an arc-shaped plate, and the arc-shaped plate includes a first arc-shaped plate 220 cooperating with the semicircular groove 120 and a second arc-shaped plate 230 cooperating with the through hole 110.

[0050] Due to the existence of the opening, the through hole 110 is semicircular, and the second arc-shaped plate 230 and the through hole 110 form a complete circular through hole for the use of the flat head bolt 300.

[0051] Similarly, the first arc-shaped plate 220 and the semicircular groove 120 form a complete circular groove.

[0052] The first arc-shaped plate 220 is provided with a limiting groove 221, and the second step 132 is provided with a positioning column 1321 cooperating with the limiting groove 221, and the first arc-shaped plate 220 abuts against the second step 132 to pass the positioning column 1321 through the limiting groove 221.

[0053] When the first arc-shaped plate 220 abuts against the second step 132, the upper end surface of the first arc-shaped plate 220 is at the same level as the ground of the semicircular groove 120, facilitating the flat head bolt 300 to press the first arc-shaped plate 220 and the semicircular groove 120 together to fix the connecting plate 200 and the fixed plate 100.

[0054] The opposite sides of the panel 210 are provided with support plates 250 used in cooperation with the first step 131, the support plates 250 are bolted with the first step 131, the panel 210 is further supported by the support plates 250, and the stability of the panel 210 is ensured.

[0055] When the flat head bolt 300 needs to be disassembled, the flat head bolt 300 is rotated, so that the screw head 310 is separated from the semicircular groove 120 and the first arc-shaped plate 220, and the bolts connecting the support plate 250 and the first step 131 also need to be disassembled. At this time, due to the arrangement of the limiting groove 221 and the positioning column 1321, the connecting plate 200 is linearly translated relative to the fixed plate 100 by a distance, and then the baffle 240 is moved away from the upper side of the flat head bolt 300, so as to disassemble the flat head bolt 300. The disassembly and installation are simpler than the buckle of the prior art.

[0056] The flat head bolt 300 comprises a screw head 310, a vertical rod and a screw rod 330, a circular limiting plate 320 is arranged between the vertical rod and the screw rod 330, the outer diameter of the vertical rod is equal to the inner diameter of the through hole 110, and the outer diameters of the circular limiting plate 320 and the screw head 310 are both greater than the outer diameter of the through hole 110; the screw head 310 can abut against the semicircular groove 120, the circular limiting plate 320 is located below the fixed plate 100, and the screw head 310 and the circular limiting plate 320 are used in cooperation to limit the up-down movement stroke of the flat head bolt 300 in the through hole 110.

[0057] The distance from the upper end surface of the circular limiting plate 320 to the bottom of the fixed plate 100 is greater than the distance from the bottom of the baffle 240 to the screw head 310.

[0058] The bottom of the fixed plate 100 is provided with a plastic buckle 140, which provides a gripping force for the fixed plate 100, and the gripping force is greater than the upward force caused by the loosening of the bolt due to vibration. Therefore, the existence of the baffle 240 further limits the flat head bolt 300, and avoids the continuous loosening and upward movement of the flat head bolt 300 due to vibration.

[0059] When the baffle 240 is moved away from the upper side of the flat head bolt 300, the personnel rotates the flat head bolt 300, and the circular limiting plate 320 applies an upward force to the fixed plate 100, thereby driving the fixed plate 100 to move upward synchronously, until the flat head bolt 300 is disassembled.

[0060] The above examples are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, but not to limit the present application, and the protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the foregoing examples, it should be understood by those skilled in the art that any person skilled in the art can modify or easily think of changes to the technical solutions recorded in the foregoing examples, or make equivalent replacement to some of the technical features within the technical range disclosed by the present application.
