Description

Technical Field

[0001] This utility model relates to sunshade curtain technology, specifically a sunshade curtain slider. Background Technology

[0002] With the development of sunshade technology, the requirements for its start-stop performance are becoming increasingly stringent. In the applicant's earlier patent application for an extension rod (202322252345.3), a pull rope is threaded through the pull rope hole on the slider and then around a fixed pulley to the outer end of the spring inside the extension rod. The pull rope passes through the inner rope hole of the slider, connecting to the spring. In actual use, the pull rope is not well constrained within a certain range connected to the spring. During the rapid shaking caused by the spring's rebound, wear is easily generated at the inner rope hole, affecting the service life. Furthermore, due to the structure where the pull rope enters from the front and then reverses to connect to the spring on the inside, the plug of the slider body into the extension rod is subjected to force when the pull rope is pulled, affecting the stability of the connection with the extension rod. The pull rope guiding accuracy of the sliders at both ends of the extension rod is extremely high. It is very easy for the two ends of the extension rod to become out of sync due to product errors or assembly errors, resulting in jamming, abnormal noise, and affecting the performance and service life. Summary of the Invention

[0003] This utility model provides a sunshade curtain slider with a simple structure that can constrain the pull rope, play a stable connection and guiding role, and ensure stable pulling performance.

[0004] The technical solution adopted by this utility model is as follows: a sunshade slider includes a sliding part and an insertion part for inserting an extension rod, which are integrally arranged in the left and right directions within a guide rail. The sliding part has a front through hole or a front through groove on its front side facing away from the sunshade roller shaft near the insertion part, and an inner through hole or an inner through groove parallel to the direction of the extension rod on its side near the insertion part. A reversing cavity is provided in the middle of the sliding part near the insertion part, with the front side of the reversing cavity connected to the front through hole or the front through groove, and the inner side connected to the inner through hole or the inner through groove. A reversing post is vertically arranged inside the reversing cavity for reversing the direction of the pull rope inserted from the front side of the reversing cavity and sending it out from the inner side. The insertion part has a connecting inner through hole or inner through groove in the left and right directions, and a guide pull rope to the extension rod through a through hole or through groove.

[0005] The reversing column is provided with a reversing guide groove at the same horizontal height as the front through hole or groove and the inner through hole or groove.

[0006] The reversing column is fitted with a reversing sleeve or a reversing bearing sleeve.

[0007] The reversing sleeve is mounted on the outside of the reversing column via a bearing.

[0008] The reversing sleeve is provided with a reversing guide groove at the same horizontal height as the front through hole or groove and the inner through hole or groove.

[0009] The insertion part includes a front insertion part and a rear insertion part connected to the inside of the sliding part. The insertion through hole or insertion through groove for threading the pull rope is opened on the front insertion part or the rear insertion part. The front insertion part and the rear insertion part are inserted into the insertion hole of the extension rod together, or inserted into the front and rear insertion holes of the extension rod respectively.

[0010] The front or rear insertion hole of the connecting part or the connecting part of the pull rope is provided with a pressure strip structure, which is inserted into the insertion groove from top to bottom.

[0011] The front or rear insertion hole of the connecting part of the pull rope is inserted into the insertion groove from top to bottom on the inner side of the extension rod.

[0012] An installation groove is provided between the front and rear insertion holes of the extension rod. The front or rear insertion part for threading the pull rope is provided with a separate or integrated installation part and an insertion part. The insertion part is inserted into the front or rear insertion hole, the installation part is snapped into the installation groove, and the insertion through hole or insertion through groove is provided on the installation part.

[0013] The insertion through hole or insertion through slot has an flared structure on the inner side of the hole or slot.

[0014] The beneficial effects of this utility model are as follows: the front and rear insertion parts are respectively inserted into the front and rear insertion holes of the extension rod, combined with the elastic snap-fit ​​part, which plays a role in stabilizing the insertion; the pull rope guide is independently set on the mounting part on the insertion part. After the front and rear insertion holes are inserted into the insertion parts of the front and rear insertion parts, the mounting part is snapped into the mounting groove between the front and rear insertion holes of the extension rod, which can effectively position and fix the insertion part, prevent the problem of displacement and wear damage caused by the swaying of the pull rope when pulled quickly and with high strength, and at the same time, it can accommodate the precision errors of product components and assembly, and meet the synchronous precision requirements of pulling at both ends of the extension rod.
