Description

Technical Field

[0001] The utility model relates to the technical field of plastic part connection, in particular to a plastic part connection structure. Background Art

[0002] Plastic parts refer to daily necessities and industrial products made of plastic as the main raw material. Plastic parts have the advantages of light weight, high strength, impact resistance, not easy to break, good insulation and heat resistance. Therefore, they are widely used in many fields such as automobile manufacturing, electronics and electrical, instrumentation, construction equipment, medical care, daily life, process manufacturing, etc. The production process of plastic parts usually includes steps such as raw material selection, formula design, molding processing and post-processing.

[0003] Most of the existing plastic parts are connected by means of snap-on, glue, screw, hinge, etc. Most snap-on connections require auxiliary parts such as screws or snap-on sheets. If the auxiliary parts are not used, the connection stability may be poor. If the auxiliary parts are used, frequent disassembly will cause wear of the plastic parts, and manual operation is required during disassembly and assembly, which is time-consuming and labor-intensive. Gluing and other methods connect two connecting parts by using sticky materials such as glue, which is difficult to disassemble after connection and cannot be reused after disassembly, resulting in increased costs. Based on these problems, Chinese patent CN219587908U discloses a plastic part connection structure, by providing a long strip plug-in portion and a plastic A long strip of interlocking part is set at the corresponding position of part B, and the interlocking path is longer. When the two plastic parts are embedded together, they are stuck to each other to prevent left and right displacement. At the same time, the rear end of the interlocking part is closed, which limits the depth of the plug-in part and reduces the possibility of displacement. By setting a limiting part to cooperate with the limiting groove, after the plug-in part is embedded in the interlocking part, the wedge-shaped block on the limiting part automatically clamps the rear end of the limiting groove, avoiding the front and rear displacement of the two plastic parts and reducing the use of auxiliary parts. When the plastic parts need to be disassembled, it is only necessary to press down the wedge-shaped block of the limiting part to complete the disassembly of the plastic parts, which saves time and effort, avoids damage to the plastic parts, saves costs, and brings convenience to the staff.

[0004] This connection structure can only realize the locking of two groups of different plastic parts. When the number of plastic parts is large, not only do the two groups of plastic parts need to be classified, but after the locking is completed, the scattered plastic parts still occupy a large working space. This process not only wastes the staff's time and physical strength, but also affects the overall practicality of the plastic part connection structure. Utility Model Content

[0017] Both ends of the opposite sides of the slide plate are fixedly connected to the bottom end of the slide rod, and a pinching piece is fixedly connected to the center of the front end of the slide plate.

[0018] As a further description of the above technical solution:

[0019] Both sides of the front end of the bottom plate are penetrated by sliding frames, the inner walls of the sliding frames are slidably connected with one end of the outer wall of the pinching piece, and the pinching piece and the sliding frame are provided with two groups.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] (1) The slider can slide on the inner wall of the slide groove plate.

In this way, multiple sets of plastic parts can be spliced ​​together from different directions, and one set of plastic parts is pressed vertically downward on the top of another set of plastic parts. At this time, the bottom inclined surface of the conical block will contact the top of the edge strip and retract. When the bottom plate of the bottom of one set of plastic parts is close to the top surface of the top plate of the other set of plastic parts, the top of the conical block will automatically insert into the conical groove. In this way, multiple sets of plastic parts can be stacked on each other, which not only saves the time and physical strength of the staff, but also improves the overall practicality of the plastic parts connection structure.

[0022] (2) When disassembling and separating plastic parts, one only needs to gently lift up a set of triangular bars, and the spring sheet connected to the lifted triangular bars will bend. At the same time, slide the slider in the opposite direction of the lifted triangular bars to disassemble and separate the plastic parts. By pinching the two sets of pinching pieces together with one hand, the conical blocks can be simultaneously dropped from the conical grooves, and the stacked plastic parts can be disassembled. When the bottom plate of one set of plastic parts is in close contact with the top surface of the top plate of another set of plastic parts, the top of the conical block will automatically insert into the conical groove, and the outer wall of the push block will slide into the sliding cavity, exerting an upward force on the bottom plate, making the installation structure of the bottom plate more stable.
