Length adjusting block and length adjusting assembly including the same

Abstract

This disclosure provides a length adjusting block and a length adjusting assembly including the same. The length adjusting block includes: a first sidewall; a second sidewall disposed substantially parallel to and spaced apart from the first sidewall; a first support and a second support disposed on a first surface of the length adjusting block; a support portion connected to the first and second sidewalls; and a rotating member including a pivot portion pivotally connected to the first and second support portions, and a pressing portion protruding outward from an outer peripheral surface of the pivot portion, the pressing portion being configured to clamp the webbing together with the support portion. The length adjusting assembly includes the length adjusting block and a pull ring member, which includes a fixed portion surrounding and fixed to the rotating member, and a movable portion divided by a seam sewn onto the pull ring member.

Claims

1. A length adjusting block for adjusting the length of a webbing of a gun sling, comprising: a first sidewall; a second sidewall disposed substantially parallel to and spaced apart from the first sidewall; a first support and a second support disposed on a first surface of the length adjusting block; a support portion connected to the first sidewall and the second sidewall; a rotating member including a pivot portion pivotally connected to the first support and the second support, and a pressing portion protruding outward from an outer peripheral surface of the pivot portion, the pressing portion being configured to clamp the webbing together with the support portion.

2. The length adjustment block as described in claim 1, wherein the distance between the outer contour of the pressing portion and the supporting portion is less than or equal to a first predetermined distance of the webbing thickness.

3. The length adjusting block as described in claim 1, wherein the distance between the outer peripheral surface of the pivot portion and the abutment portion is greater than a second predetermined distance of the webbing thickness.

4. The length adjusting block as described in claim 1, wherein when the rotating member is in a first state where the pressing part contacts the webbing, the pressing part and the supporting part together clamp the webbing.

5. The length adjusting block as described in claim 1, wherein when the rotating member is in a second state in which the pressing portion does not contact the webbing, the webbing can pass through a gap between the pivot portion and the supporting portion.

6. The length adjusting block as described in claim 1, further comprising a first guide portion and a second guide portion disposed between the first sidewall and the second sidewall, the first guide portion being configured to guide the webbing through a first elongated hole, and the second guide portion being configured to guide the webbing through a second elongated hole, the first elongated hole and the second elongated hole being respectively positioned on both sides of the abutment portion.

7. The length adjustment block as claimed in claim 6, wherein the first guide portion has a first inclined surface that is inclined toward the first elongated hole, and the second guide portion has a second inclined surface that is inclined toward the second elongated hole.

8. A length adjustment component, comprising: The length adjustment block as described in request item 1; And a pull ring component, which includes a fixed portion that surrounds and is fixed to the rotating component, and a movable portion that is divided by a seam sewn onto the pull ring component.

9. The length adjustment assembly as claimed in claim 8, wherein the pull ring includes a belt body, and the fixing portion of the belt body includes: A first fixed section is abutted and positioned against a first side of a lever portion of the rotating member, the lever portion being attached to the pivot portion; a first bent portion is connected to the first fixed section, which surrounds and abuts against the inner wall of an elongated hole in the lever portion; a second fixed section is connected to the first bent portion, the second fixed section abutting and positioned against a second side of the lever portion; and a third fixed section is abutted and positioned against the outer side of the first fixed section.

10. The length adjustment assembly as claimed in claim 9, wherein the fixing part further includes a fixing member that passes through a hole in the lever part to fix the first fixing section, the second fixing section, and the third fixing section of the belt to the lever part.
