Product Description:
Hexagon nuts are used in conjunction with bolts and screws to connect and tighten mechanical components. Among them, 1
Hexagonal high-strength nuts are the most widely used, while C-grade high-strength nuts are used for machines with rough surfaces and low precision requirements
In terms of equipment or structure; A-grade and B-grade nuts are used for machines, equipment, or structures with relatively smooth surfaces and high precision requirements
Up there. The thickness m of type 2 hex nuts is relatively thick and is often used in situations where assembly and disassembly are frequently required. The thickness m of the hexagonal thin nut is relatively small
Thin, often used in situations where the surface space of the connected components is limited.
Hexagonal nuts are classified into three types based on their nominal thickness: Type I, Type II, and Thin. Nuts above level 8 are divided into two types: Type 1 and Type II
Types.
Type I hex nuts are the most widely used, while Type 1 nuts are divided into three grades: A, B, and C. Among them, Grade A and B nuts are suitable for
On machines, equipment, and structures with low surface roughness and high precision requirements, C-grade nuts are used for surfaces that are relatively rough
On machines, equipment, or structures that do not require high precision; The thickness of type 2 hex nuts is relatively thick and is often used for frequent assembly and disassembly
The occasion.
Type 1 nut refers to a regular hexagonal nut with a nominal height m ≥ 0.8D, and its type and size should comply with GB/T6170
The regulations;
The height of type 2 nuts is higher than that of type 1 nuts, and their type and size should comply with GB/T6175. Add type 2 nuts
The purpose is twofold: firstly, to obtain a cost-effective nut that does not require heat treatment by increasing the height of the nut.
Because Grade 8 Type 1 nuts with D ≤ M16 do not require heat treatment, only Grade 8 nuts with D>M16~39
The specification only uses type 2 nuts, obviously the type 1 nuts that do not require heat treatment cannot meet the mechanical performance requirements of grade 9 nuts. regulations
Another purpose of type 2 nuts is to obtain 12 grade nuts with better toughness. Due to the increase in the height of the nut, it undergoes lower quenching
Under tempering hardness, the guaranteed stress index can be achieved, thus increasing the toughness of the nut.
Classified by tooth spacing: standard teeth, regular teeth, fine teeth, extremely fine teeth, and reverse teeth.
Classified by material: stainless steel hex nut, carbon steel hex nut, copper hex nut, iron hex nut.
Classified by thickness: hexagonal thick nuts and hexagonal thin nuts.
Classified by usage: Hot melt copper nuts, hot pressed copper nuts, embedded copper nuts, and ultrasonic copper nuts

The window regulator motor is the power source of the window glass lifting system, responsible for driving the glass up and down. It is usually installed inside the car body or in the car door, connected to the window glass through steel wire ropes or guide rails, to achieve the control of the window lifting. The working principle of a motor is based on electromagnetic induction and changes in the direction of current. By changing the direction of current, the motor’s forward and reverse rotation can be controlled, thereby achieving the up or down movement of the car window. The start and stop of the motor are controlled by the switch inside the car, making it convenient for the driver to operate. In addition, in order to protect the motor, wire rope, and guide rail, a lubrication system is also installed in the system to provide lubricating oil for these components, reduce friction, and extend service life.

Introduction: Automotive glass lifters are generally composed of the following parts: control mechanism (rocker arm or electric control system), transmission mechanism (gear, toothed plate or rack, gear flexible shaft meshing mechanism), glass lifting mechanism (lifting arm, motion bracket), glass support mechanism (glass bracket) and stop spring, balance spring. The basic working route of a glass lifter is the control mechanism → transmission mechanism → lifting mechanism → glass support mechanism. The balance spring is used to balance the gravity of the glass to reduce the operating force; The stop spring installed between the small gear and the support seat is used to hold the glass (stop) and ensure that it stays in the required position.

A hinge is a mechanical device used to connect two solids and allow for relative rotation between them. It is usually composed of movable components or foldable materials. The main function of the hinge is to assist in the opening and closing of the cabinet, by connecting the rotating pair, so that the door or cover can swing on the fixed frame. According to different installation positions, hinges can be divided into door hinges and cabinet hinges. Door hinges are used to allow doors to rotate naturally and smoothly to open and close, while cabinet hinges have more functions and designs, such as rotating 360 degrees, adjusting the gap between doors up, down, and left and right.
