Linear transmission module

A linear transmission module, comprising:

• a slider body, wherein a length direction is set as a first direction, a width direction is set as a second direction, a thickness direction is set as a third direction, and the first direction, the second direction, and the third direction are perpendicular to each other;
• two end caps, respectively arranged at two opposite ends of the slider body in the first direction, wherein each of the end caps comprises at least two assembly grooves correspondingly arranged in the second direction, each of the assembly grooves extends through the end cap in the first direction, each of the assembly grooves comprises an abutting surface, a clamping portion, and an assembly surface, the clamping portion is respectively connected to the abutting surface and the assembly surface, the abutting surface and the assembly surface are opposite surfaces, and a minimum distance between the abutting surface and the assembly surface in a fourth direction is smaller than a maximum distance of the clamping portion in the fourth direction;
• and
• at least two dustproof members, extending in the first direction, wherein one end of each of the dustproof members in the first direction is assembled in the assembly groove of one of the end caps, the other end of each of the dustproof members in the first direction is assembled in the assembly groove of the other of the end caps, each of the dustproof members comprises a dustproof member body, a first contact portion, and a second contact portion, the first contact portion and the second contact portion are respectively located on two opposite sides of the dustproof member body that are perpendicular to the first direction, protrude from the dustproof member body in the fourth direction of the dustproof member body, and are in a symmetrical shape;
• wherein a through groove running through the first direction is comprised inside the end cap, the through groove comprises two inner surfaces of the end cap in the second direction of the end cap, and the two assembly grooves are correspondingly arranged on the two inner surfaces of the end cap;
• wherein a rail groove running through the first direction is provided inside the slider body, the rail groove comprises two slider body inner surfaces in the second direction of the slider body, and forms an opening in the third direction,
• the slider body further comprises two outer retainers, the two outer retainers are respectively arranged on two opposite slider body inner surface and are adjacent to the opening,
• each of the outer retainers comprises an accommodation groove running through in the first direction and corresponds to one of the assembly grooves, and
• when two opposite ends of each of the dustproof members are respectively assembled in one of the assembly grooves of the two end caps, a part of each of the dustproof members is accommodated in one of the accommodation groove.
