Embodiment 1

[0012] In this embodiment, a double-thread screw includes a stainless steel or carbon steel rod body 1. The front end of the rod body 1 is provided with a wood thread 2, and the end of the wood thread 2 is connected to the rod body to be an external hexagon 3; the rear end of the rod body 1 is provided with a machine thread 4; There is an octagonal star hole in the cross section of the threaded tail of the rod body 1; use a wrench to turn the hexagonal part of the screw rod to drill the wood thread into the connecting object to fix it, and punch a hole equivalent to the diameter of the screw rod. , Pass through the threaded part of the end of the screw, use a nut to hide and fix the screw in the object to be connected. The outer end of the hole end of the object has a slightly wider diameter to accommodate the nut, so that the nut is hidden in the object at the same time; when it needs to be removed, use a screw The knife tool acts on the octagonal star at the end to unscrew the...

Abstract

The invention discloses a double tooth screw which comprises a stainless steel or carbon steel rod body. A wood thread is arranged at the front end of the rod body, the connection rod body part of the tail end of the wood thread is formed into an external hexagon, the rear end of the rod body is provided with a machine thread, and an eight pointed star-shaped hole is formed in the section of the tail of the machine thread at the rear end of the rod body. The double tooth screw is used for connecting furniture and pipelines and solving the problems of inconvenience and deconstructive damage during assembly and disassembly, so that connection stability during assembly is ensured, and meanwhile the screw is concealed in an object needing to be connected without influencing the attractive appearance effect.

Description

technical field [0001] The invention relates to a double tooth screw. Background technique [0002] Usually in the furniture and decoration industry, a detachable structure is often used, and a side-embedded aluminum rotating locking disc and a locking pin connected to the locking disc in parallel and in the same direction are used to form a locking system in the connection. The other end of the pin is screwed with a plastic nut vertically connected to another object to form a right-angle connection. Because the connection requires an external screwdriver to rotate and lock the screwdriver to rotate and lock, the side of the connection plate exposed by the locking disk will affect the appearance, and the connection is fitted with a rotating wedge surface, the fixed locking arm is long, the fixed nut is short and hard fit, so it is easy to install Errors occur, and after locking, it is easy to loosen under the action of external forces such as vibration and twisting. When i...
