For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0029] In the related technical field, the optical module pull ring includes a hardware part and a plastic part, which is usually composed by integrally injection molding the hardware and the plastic, but the structure has low production efficiency and high machine occupancy, which greatly affects the product cost.

[0030] Therefore, the utility model provides an optical module pull ring, at least one connecting part of the pull ring body is hot melt connected with the sub-arm part of the cantilever, without additional mold, the production process is more simple and efficient.

[0031] Please refer to Figure 1 The utility model provides a kind of optical module pull ring, including pull ring body 10 and cantilever 20.

[0032] Wherein, pull ring body 10 is the plastic part in optical module pull ring, cantilever 20 is the metal part in optical module pull ring.

[0033] Specifically, the pull ring body 10 comprises a main body part 11 and two connecting parts 12 outwardly extending from the main body part 11, the two connecting parts 12 are arranged at intervals, and the cantilever 20 comprises two sub-arm parts 21 arranged at intervals, wherein at least one connecting part 12 is hot melt connected with the corresponding sub-arm part 21.

[0034] It can be understood that the main body part 11 is a part for a user to hold, so the main body part 11 has a ring-shaped structure design for the hand to pull, the connecting part 12 is a part outwardly extending from the main body part 11 and used for connecting with the cantilever 20, and the two sub-arm parts 21 of the cantilever 20 are corresponding parts of the two connecting parts 12 and are connected with the corresponding connecting parts 12, respectively.

[0035] Here, the hot melt connection refers to that after the connecting part 12 is formed, the shape of the connecting part 12 is secondarily shaped by reheating to form a corresponding connecting structure, and after cooling, the connecting structure is connected with the sub-arm part 21.

[0036] For example, a micro, convex-concave, anti-slip surface can be formed on the surface of the sub-arm part 21, then the connecting part 12 in a hot melt state is abutted against the anti-slip surface, the anti-slip surface is used to increase the connecting contact area between the sub-arm part 21 and the connecting part 12, so that the connection is realized.

[0037] For example, a convex column can be arranged on the sub-arm part 21, a hollow structure convex column is arranged on the connecting part 12, the convex column is arranged in the hollow structure convex column, then the hollow structure convex column in a hot melt state is extruded, so that the tolerance fit level of the two is improved, and the connection is realized.

[0038] For example, an opening can be arranged on the sub-arm part 21, a convex column is arranged on the connecting part 12, the convex column is arranged in the opening, and the convex column in a hot melt state is pressed in the axial direction, so that the shape structure of the convex column is changed, and the connection with the sub-arm part 21 is realized.

[0039] Compared with the integrated injection connection mode, the optical module pull ring of the utility model connects at least one connecting part 12 of the pull ring body 10 to the sub-arm part 21 of the cantilever 20 through hot melt connection, and is more simple and efficient.

[0040] Please refer to Figures 1 to 4 In some embodiments, the connecting part 12 is provided with a mounting convex column 13, the sub-arm part 21 is provided with a mounting hole 22 for arranging the mounting convex column 13, the mounting convex column 13 is hot melt connected to the sub-arm part 21 and covers the mounting hole 22.

[0041] It can be understood that the mounting protrusion 13 is protruded on the surface of the connecting portion 12, and the mounting hole 22 is connectable with the mounting protrusion 13. Here, the hole shape of the mounting hole 22 is not limited, which can be circular, square, polygonal, etc. The step of heat melting the mounting protrusion 13 is to apply pressure to the mounting protrusion 13 in the protruding direction in the molten state, so that the mounting protrusion 13 is deformed, and the height of the mounting protrusion 13 is compressed and covers the mounting hole 22. After the mounting protrusion 13 cools and solidifies, it forms a connection relationship with the mounting hole 22.

[0042] Please refer to Figures 1 to 4 In some embodiments, the connecting portion 12 is provided with a mounting groove 14, the mounting protrusion 13 is arranged on the groove wall of the mounting groove 14, and the sub-arm portion 21 is arranged at the mounting groove 14.

[0043] It can be understood that the mounting groove 14 can limit the position of the sub-arm portion 21 to limit the connection angle and position between the sub-arm portion 21 and the connecting portion 12.

[0044] Please refer to Figures 1 to 4 In some embodiments, the mounting protrusion 13 includes a first column segment 131 penetrating the mounting hole 22 and a second column segment 132 connected to the first column segment 131, and the diameter of the second column segment 132 is greater than the inner diameter of the mounting hole 22.

[0045] Here, the first column segment 131 and the second column segment 132 are the structural forms of the mounting protrusion 13 after heat melting connection with the mounting hole 22. Here, the first column segment 131 should be adapted to the mounting hole 22, and the second column segment 132 is similar to a screw, which forms an interaction force with the connecting portion 12 to meet the connection requirement.

[0046] Please refer to Figures 1 to 4 In some embodiments, the sub-arm portion 21 is provided with a limiting portion 23, and the groove wall of the mounting groove 14 is provided with a limiting matching portion 15 matched with the limiting portion 23.

[0047] It can be understood that the limiting portion 23 and the limiting matching portion 15 limit the position of the sub-arm portion 21 relative to the connecting portion 12, prevent unnecessary position movement of the sub-arm portion 21 during the heat melting connection process, and also prevent relative movement after the heat melting connection.

[0048] Here, the limiting portion 23 can be a notch, a protrusion, or a combination of the two. Similarly, the limiting matching portion 15 can also be a protrusion, a notch, or a combination of the two.

[0049] Please refer to Figures 1 to 4 In some embodiments, the mounting hole 22 is a circular hole, the limiting portion 23 includes a recess formed on the sub-arm portion 21, and the limiting matching portion 15 includes a protrusion formed on the groove wall of the mounting groove 14.

[0050] It can be understood that when the mounting hole 22 is a circular hole, the mounting convex column 13 and the mounting hole 22 are in clearance fit, and the mounting convex column 13 can rotate in the mounting hole 22, therefore, the concave and convex parts are matched to prevent the mounting convex column 13 from rotating in the mounting hole 22.

[0051] In some embodiments, the mounting hole 22 is a non-circular hole.

[0052] It can be understood that when the mounting hole 22 is a non-circular hole, that is, the mounting hole 22 is a square hole, a polygonal hole or an oval hole, the limiting action between the mounting hole 22 and the mounting convex column 13 can be used to prevent the mounting convex column 13 from rotating in the mounting hole 22.

[0053] In some embodiments, the sub-arm part 21 is formed with an anti-skid layer on the end face of the second column segment 132.

[0054] It can be understood that the anti-skid layer is a rough layer structure formed on the sub-arm part 21, which can increase the contact area between the sub-arm part 21 and the second column segment 132, especially after the second column segment 132 is melted.

[0055] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
