Embodiment 1

[0013] Embodiment 1: A kind of pagoda-type double-headed pulling screw, its structural schematic diagram is as follows figure 1 As shown, it includes column step 2 and column 1.

[0014] The cylinder 1 is divided into a left cylinder and a right cylinder, which are arranged at both ends of the cylinder step 2 respectively in the form of mirrors, and their structures are identical. Therefore, only the structure of one of the main bodies will be described in detail below.

[0015] A terminal 4 is provided on the top of the cylinder 1, and the section of the terminal 4 is trapezoidal or triangular. When the section of the terminal 4 is trapezoidal, the top of the screw is a flat head, which avoids the damage of the screw to the product shell and plays a role in protecting the shell; when the section of the terminal 4 is triangular, the top of the screw is pointed, The screw can go deep into the product shell under pressure, which increases the fastness, and at the same time, fur...

Abstract

The invention discloses a pagoda double-end opposite pulling screw. The pagoda double-end opposite pulling screw comprises a cylinder step, and cylinders respectively arranged at two ends of the cylinder step in a mirror plane manner; an end is arranged at the top end of the cylinder; at least one barb is arranged between the cylinder step and the end; the section of the barb is trapezoidal; and the top surface of the trapezoid is towards the end. The trapezoidal bottom angle of the section of the barb is 45 degrees; and the barb at the topmost end is tightly combined with the end. The pagoda double-end opposite pulling screw is in interference fit with a fixed hole formed in a product shell for use, is fastened without depending on a traditional tool, and is directly clamped by pressing, so that the demands of products with higher appearance requirements can be satisfied; the fixed products cannot be dismounted to improve the secrecy of the products; and the internal connection realizes high integrity and local generality and specificity.

Description

technical field [0001] The invention relates to a screw, in particular to a pagoda-type double-head pull screw. Background technique [0002] Screws are used as fasteners, which are very common in the market at present. The most commonly used screws are self-tapping screws. Tap the thread directly. It is often used to connect metal plates with thinner thickness. There are two types of self-tapping screws with tapered ends and self-tapping screws with flat ends. However, self-tapping screws can only be tightened with tools from the outside. During the rotation process, the cooperation with the carrier is easy to loose after being fixed, which affects the firmness of the fastener and the carrier. It is also easy to disassemble, which affects the confidentiality of the product. Not strong. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a pagoda-type double-headed pull screw with high firmness and not easy to disassem...
