Z-shaped rope positioning system for abat vent pull rod

Abstract

The invention discloses a Z-shaped rope positioning system for an abat vent pull rod. The Z-shaped rope positioning system includes jackscrews, copper binding posts, locking rope springs, positioningblocks and nylon ropes in four plastic slotting angles, wherein the nylon ropes are arranged at the horizontal parts of the plastic slotting angles in the horizontal direction; the copper binding posts are sleeved with the head ends of the nylon ropes; the horizontal tail ends of the nylon ropes at the plastic slotting angles are sleeved with the fixed positioning blocks; the nylon ropes between the positioning blocks and the copper binding posts are sleeved with the locking rope springs; the two nylon ropes respectively connected with the opposite plastic slotting angles penetrate through a horizontal pull rod from the two sides simultaneously. According to the positioning system, the nylon ropes penetrate through the pull rod simultaneously, the pull rod can stay at any position throughfriction; the locking rope springs are mounted at all the ends of the nylon ropes for buffering, so as to guarantee that the pull rod beginning to start cannot be clamped when bearing too big tension,and the entire process is smooth; maintenance and adjustment are convenient, the outer dimension of a hatch is reduced, and the appearance is more beautiful and ingenious.

Description

technical field [0001] The invention belongs to the technical field of caravan accessories, and in particular relates to a Z-shaped rope positioning system for a pull rod of a sunshade curtain, which is applied to the positioning of any position within the sliding range of a cloth curtain and a gauze curtain of a sunshade of a caravan. Background technique [0002] At present, in order to adapt to the diversity of heights from 300mm to 1100mm for the sunshade of the caravan, the height and thickness of the hatch cover of the cloth roll are relatively large, and the Z-shaped rope and the fixed buffer block are in a straight line, and the fixed buffer block is hidden. In the hatch cover, the hatch cover cannot be reduced in the height direction, which affects the interior space and appearance optimization of the RV. [0003] On the other hand, after the sunshade is used for a period of time, the positioning of the pull rod will become loose, and the current structure is diffic...

Problems solved by technology

[0002] At present, in order to adapt to the diversity of heights from 300mm to 1100mm for the sunshade of the caravan, the height and thickness of the hatch cover of the cloth roll are relatively large, and the Z-shaped rope and the fixed buffer block are in a straight line, and the fixed buffer block is hidden. In the hatch cover, the hatch cover cannot be reduced in the height direction, which affects the interior space and appearance optimization of the RV

[0003] On the other hand, after a period of use of the sunshade, the positioning of the tie rod will become loose, and the current structure is difficult to operate during maintenance and adjustment.
