            Lò xo kéo (tiếng Anh: Extension Spring, tiếng Trung:  拉弹簧) là một loại lò xo có chức năng chống lại lực kéo dãn.

            Đặc điểm của lò xo kéo:<br />
&nbsp;• Hình dạng: thường là cuộn xoắn tròn, hai đầu có móc hoặc vòng để liên kết với các chi tiết khác.<br />
&nbsp;• Nguyên lý hoạt động: khi hai đầu bị kéo ra xa, lò xo sẽ tích trữ năng lượng đàn hồi và cố gắng co lại về trạng thái ban đầu.<br />
&nbsp;• Vật liệu: thường chế tạo từ thép đàn hồi (như thép Cacbon, Inox, SWP…).<br />
<br />
Ứng dụng của lò xo kéo:<br />
&nbsp;• Cửa cuốn, cửa kéo tự động.<br />
&nbsp;• Xe máy, ô tô (giảm chấn, phanh).<br />
&nbsp;• Đồ gia dụng: máy giặt, ghế gấp, dụng cụ thể thao.<br />
&nbsp;• Máy móc công nghiệp cần lực đàn hồi kéo.<br />
<br />
👉 Nói ngắn gọn: Lò xo kéo là lò xo chuyên dùng để tạo ra lực đàn hồi khi bị kéo giãn, giúp các chi tiết cơ khí trở về vị trí ban đầu.<br />
