[0020] Please see Figure 1-4The present invention provides an embodiment of an easy-to-disassemble connection method for injection molded parts, comprising a connecting assembly 1 and two end cap assemblies 2. The connecting assembly 1 includes a mounting cylinder 101, with slots 102 at both ends and a slot 103 in the middle. The slots 103 are connected to the slots 102 in sequence, improving the convenience of part installation. Two protrusions 104 are symmetrically fixed on the inner sidewalls of the slots 102. Both the protrusion 104 and the end cap assemblies 2 are made of plastic and are injection molded. Each end cap assembly 2 includes a circular end face 201. Two arc-shaped plates 202 are symmetrically fixed to the surface of each circular end face 201. The circular end face 201 and the arc-shaped plates 202 are both made of plastic and are integrally formed by injection molding. The external dimensions of the arc-shaped plates 202 are sequentially adapted to the internal dimensions of the slot 102, improving the ease of installation and positioning of the circular end face 201 and the mounting cylinder 101. The arc-shaped plates 202 are sequentially engaged... Inside the slot 102, each end of the arc-shaped plate 202 is provided with a slot 203 for the protrusion 104 to engage. The external dimensions of the protrusion 104 are adapted to the internal dimensions of the slot 203. The operator can insert the arc-shaped plates 202 into the slot 102 in sequence, thereby improving the convenience of installing and positioning the mounting cylinder 101 and the circular end face 201. The operator then rotates the circular end face 201 counterclockwise, so that the protrusion 104 is engaged in the two sets of slots 203 in sequence. The operator then rotates the circular end face 201 clockwise, thereby limiting the displacement of the arc plate 202 and improving the convenience of connecting the mounting cylinder 101 and the circular end face 201. The operator then rotates the circular end face 201 clockwise, causing the protrusion 104 to slide out of the inside of the slot 203 in sequence, thereby releasing the restriction on the arc plate 202. The operator then pulls the circular end face 201 outward, which can pull the arc plate 202 out of the slot one 102, thereby exposing the slot one 102 and the slot two 103, thereby improving the convenience of disassembling the injection molded part.

[0021] Each of the protrusions 104 has a groove 106 in the middle, and a magnet 105 is snapped into the inside of each groove 106. The external dimensions of the magnet 105 are adapted to the internal dimensions of the groove 106, which improves the stability of the magnet 105 installation. Each of the slots 203 has an iron block 204 fixed on its inner sidewall. Each of the iron blocks 204 has a groove 206 in the middle, and an internal hexagon bolt 205 is threaded into the inside of the groove 206. The internal hexagon bolt 205 is threaded into the groove 206 and the inner sidewall of the slot 203, and the external dimensions of the internal hexagon bolt 205 are adapted to the internal dimensions of the groove 206, which improves the stability of the iron block 204 installation. The iron block 204 can be attracted to the magnet 105, which improves the stability of the protrusion 104 snapping into the slot 203, thereby limiting the displacement of the arc plate 202 and improving the stability of the circular end face 201 installation.

[0022] Working principle: This type of injection molded part features an easy-to-disassemble connection method. During use, the operator first inserts the arc-shaped plate 202 into the slot 102, thereby improving the ease of installation and positioning of the mounting cylinder 101 and the circular end face 201. The operator then rotates the circular end face 201 counterclockwise, causing the protrusion 104 to engage sequentially within the two sets of slots 203, thus restricting the displacement of the arc-shaped plate 202. The iron block 204 then sequentially attracts the magnet 105, further enhancing the engagement of the protrusion 104 and the arc-shaped plate 202 within the slots 203 and the slot 102. 2. Internal stability: When it is necessary to disassemble the parts inside the inspection slot 203 of the circular end face 201, the operator can rotate the circular end face 201 clockwise, so that the circular end face 201 and the arc plate 202 cancel the attraction between the magnet 105 and the iron block 204, so that the protrusion 104 slides out of the inside of the slot 203 in sequence, thereby releasing the limitation on the arc plate 202. The operator can then pull the circular end face 201 outward to pull the arc plate 202 out of the slot 102, thereby exposing the slot 102 and the slot 203, thus improving the convenience of disassembling the injection molded parts.
