[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a quick-connect injection molding spool is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, a quick-connect injection molding spool according to an embodiment of the present invention includes a spool cylinder 1 and an inner cylinder 4. Flange plates 2 are connected to both ends of the spool cylinder 1, and an inner cylinder 4 is disposed inside the spool cylinder 1. Arc strips 5 connect the inner cylinders 4. An upper retaining strip 6 is installed at one end of the outer wall of the spool cylinder 1, and a lower retaining strip 7 is installed at the other end of the outer wall of the spool cylinder 1. Flared openings 3 are formed at both ends of the inner cylinder 4, penetrating the flange plates 2. The other ends of the upper retaining strip 6 and the lower retaining strip 7 are cantilevered. One end of both the upper retaining strip 6 and the lower retaining strip 7 is fixedly connected to the outer wall of the spool cylinder 1, and the upper retaining strip 6 and the lower retaining strip 7 are respectively located on the spool cylinder. At the top and bottom of 1, the gaps between the upper clamping strip 6 and the lower clamping strip 7 and the shaft cylinder 1 are smaller than the wire diameter. When winding the wire, one end of the wire can be pressed against the shaft cylinder 1 and inserted between the lower clamping strip 7 and the shaft cylinder 1. The elasticity of the lower clamping strip 7 is used to squeeze one end of the wire, completing a quick connection. This saves the workers the trouble of winding the wire and improves the convenience and connection speed. At the same time, after the wire is wound, the workers can insert the other end of the wire into the upper clamping strip 6 and the shaft cylinder 1 in the same way to squeeze and fix the other end, preventing the wire end from falling off and causing the wire to become messy, thus improving stability.

[0028] In one embodiment, the shaft cylinder 1, inner cylinder 4, flange plate 2, and flared mouth 3 are arranged coaxially to improve rotational stability.

[0029] In one embodiment, the arc strip 5 bends inward, and multiple sets of arc strips 5 are arranged at equal angles along the vertical central axis of the shaft cylinder 1 to improve the snap-fit ​​efficiency. The inward bending of the arc strip 5 provides elasticity. When inserted into the surface of the mounting rod, the inner surface of the arc strip 5 deforms and squeezes the mounting rod, fixing the shaft cylinder 1 through friction and lateral clamping force, thereby achieving rapid and stable installation of the shaft cylinder 1 and further improving the convenience of connection. At the same time, the flared mouth 3 enlarges the outer diameter of the inner cylinder 4 port, facilitating rapid insertion and reducing the difficulty of alignment and insertion, further improving the convenience of connection.

[0030] In one embodiment, the upper clamping strip 6 and the lower clamping strip 7 are integrally arranged with the shaft cylinder 1, and the gaps between the upper clamping strip 6 and the lower clamping strip 7 and the outer wall of the shaft cylinder 1 are both smaller than the wire diameter. The upper clamping strip 6 and the lower clamping strip 7 have elasticity and deform to generate a rebound force after being squeezed by the wire. The extrusion force generated by the elasticity is used to fix the wire.

[0031] In one embodiment, the inner cylinder 4, the flared mouth 3, and the flange plate 2 are integrally arranged with the shaft cylinder 1, wherein the integral arrangement of the shaft cylinder 1 and the flange plate 2 is a common connection form in the art.

[0032] In one embodiment, the outer wall of the shaft cylinder 1 is provided with through holes 8, and multiple sets of through holes 8 are densely and evenly arranged to reduce the weight and increase the surface friction, while also increasing the air permeability.

[0033] Working principle: One end of the upper clamping strip 6 and the lower clamping strip 7 are fixedly connected to the outer wall of the shaft cylinder 1, and the upper clamping strip 6 and the lower clamping strip 7 are located at the top and bottom of the shaft cylinder 1, respectively. The gap between the upper clamping strip 6 and the lower clamping strip 7 and the shaft cylinder 1 is smaller than the wire diameter. When winding the wire, one end of the wire can be pressed against the shaft cylinder 1 and inserted between the lower clamping strip 7 and the shaft cylinder 1. The elasticity of the lower clamping strip 7 is used to hold one end of the wire in place, completing a quick connection. This eliminates the trouble of winding by the operator and improves the convenience and connection speed. At the same time, after winding is completed, the operator can insert the other end of the wire in the same way. Between the upper clamping strip 6 and the shaft cylinder 1, the other end is clamped and fixed, avoiding the problem of wire tangling caused by wire detachment and improving stability. At the same time, the arc strip 5 bends inward and has elasticity. When inserted into the surface of the mounting rod, the inner surface of the arc strip 5 deforms and squeezes the mounting rod, fixing the shaft cylinder 1 through friction and lateral clamping force, thereby achieving quick and stable installation of the shaft cylinder 1 and further improving the convenience of connection. Meanwhile, the flared mouth 3 enlarges the outer diameter of the inner cylinder 4 port, which facilitates quick insertion and reduces the difficulty of alignment and insertion, further improving the convenience of connection.
