Description

Technical Field

[0001] This utility model relates to connectors, specifically to a tension adjustment assembly. Background Technology

[0002] The connector includes: an adjustment plate inside the main body and an adjustment window on the main body. The adjustment plate has an upper hole and a lower hole, which are located inside the adjustment window. The operating end of the pull rope passes through the upper hole and the lower hole in sequence. Pulling the operating end of the pull rope downwards causes the adjustment plate to move downwards. The adjustment plate and the main body cooperate to clamp the pull rope. However, when releasing the pull rope, the main body needs to be flipped outwards, and the tension of the pull rope is used to move the adjustment plate upwards, which is very inconvenient to operate. Utility Model Content

[0003] In view of the above problems, this utility model proposes a tension adjustment combination device.

[0004] A tension adjustment assembly includes a main body and a pull rope, the main body and the pull rope being connected by a connecting structure. The connecting structure is characterized by a housing fitted onto the lower end of the main body with a clearance fit. The housing has a hole A, and the lower end of the main body has a hole B. The pull rope passes through the hole formed by holes A and B. The housing moves up and down along the lower end of the main body, moving back and forth between a loosened position and a clamped position. When the housing is in the loosened position, holes A and B are opposite, and the pull rope is loose. When the housing is in the clamped position, holes A and B are offset, and the pull rope is clamped by the housing.

[0005] Further refining the above technical solution, the main component is a hook.

[0006] Further refining the above technical solution, the lower end of the main body is flat; the flat design is more conducive to clamping the pull rope and preventing it from loosening; it is also more conducive to the setting of multiple holes.

[0007] To further refine the above technical solution, when the sleeve is in the clamping position, the hole A is located below the hole B; the sleeve moves upward along the lower end of the main body to the loosening position and downward to the clamping position.

[0008] Further refining the above technical solution, the lower end of the casing is a pressing part, which leaves space between itself and the lower end of the main body; by pressing the pressing part upwards, the casing moves upwards; operation is convenient.

[0009] Further refining the above technical solution, the casing is provided with hole C, the lower end of the main body is provided with hole D, the pull rope passes through the hole formed by hole C and hole D, and hole D is an oblong hole; by pulling the pull rope downwards, the casing moves downwards; the operation is convenient; one end of the pull rope is the operating end.

[0010] To further refine the above technical solution, the hole formed by hole C and hole D is located at the top and is called the upper hole, while the hole formed by hole A and hole B is located at the bottom and is called the lower hole; the pull rope passes through the upper hole and folds back through the lower hole.

[0011] Further refining the above technical solution, there are two holes A, two holes B, two holes C, and two holes D, and a total of two pull ropes.

[0012] The above technical solution is further refined by connecting the operating ends of the two pull ropes.

[0013] The above technical solution is further refined so that holes A, B, C, and D are arranged side by side.

[0014] The advantages of this utility model are that it has a reasonable design and simple structure. It adopts a shell design, in which the shell is fitted onto the lower end of the main body and moves up and down along the lower end of the main body. The layout is more reasonable, which provides the basic conditions for further designing the pressing part to press upward and move the shell upward to release the pull rope, and designing the pulling part to pull downward and move the shell downward to clamp the pull rope.

[0018] The figure shows hook 1, hole B 1-2, hole D 1-1, pull rope 2, casing 3, hole A 3-2, hole C 3-1, and pressing part 4. Detailed Implementation

[0019] like Figure 1-3 As shown, a tension adjustment combination device includes a hook 1 and two pull ropes 2. The hook 1 and the two pull ropes 2 are connected by a housing 3. The lower end of the hook 1 is flat. The lower end of the housing 3 is a pressing part 4.

[0020] The sleeve 3 is fitted onto the lower end of the hook 1 with a clearance fit. The sleeve 3 has two holes A 3-2 and two holes C 3-1, with holes A 3-2 and C 3-1 arranged side by side. The lower end of the hook 1 has two holes B 1-2 and two holes D 1-1, with holes B 1-2 and D 1-1 arranged side by side. Holes A 3-2 and B 1-2 form two lower holes, and holes C 3-1 and D 1-1 form two upper holes. Two pull ropes 3 pass through the upper holes and fold back through the lower holes, respectively. The operating ends of the two pull ropes 3 are connected. There is a space between the lower end of the sleeve 3 and the lower end of the hook 1. Hole D 1-1 is an oblong hole.

[0021] In use, hook 1 hooks onto the backpack body (top), and the connecting ends of the two pull ropes 2 are connected to the backpack body (bottom). Press the pressing part 4 upward to move the cover 3 upward to the loose position, and pull the two pull ropes 2 (operating ends) downward to move the cover 3 downward to the clamping position. When the cover 3 is in the loose position, the two holes A 3-2 are opposite to the two holes B 1-2, and the two pull ropes 2 are loose. When the cover 3 is in the clamping position, the two holes A 3-2 are offset from the two holes B 1-2 and are located below the two holes B 1-2, and the two pull ropes 2 are clamped by the cover 3.
