The positioning combination method of the decorative line body 1 and the positioning installation strip 302 is simple and easy to achieve.

[0042] See also Figure 1-Figure 9 As shown, both sides of the decorative line body 1 can be detachably installed with blocking and limiting components 2 for preventing the decorative line body 1 and the positioning assembly 3 from being separated from each other in the horizontal direction. Specifically, the blocking and limiting components 2 include side baffles 201 and locking rods 205. There are two side baffles 201 and they are respectively attached to the two side end positions of the decorative line body 1. The end surfaces of the two sides of the decorative line body 1 are both provided with locking holes 206 in the horizontal direction at the positions before and after the positioning installation groove 301. The front and rear positions of the side baffles 201 are both provided with matching holes 204 in the horizontal direction. The matching holes 204 are all through holes and are respectively coaxially aligned with the locking holes 206 in the horizontal direction. The matching holes 204 are coaxially inserted with locking rods 205 in the horizontal direction, and the inner ends of the locking rods 205 are coaxially detachably connected with the corresponding locking holes 206. The outer ends of the locking rods 205 are coaxially fixed with end heads 202, and the end heads 202 are pressed tightly against the outer end faces of the corresponding side baffles 201. The effect of such a setting is that through holes By adding blocking and limiting components 2 on both sides of the decorative line body 1, the decorative line body 1 can be prevented from being separated from the positioning assembly component 3, thereby completing the accurate limiting and fixing of the decorative line body 1 at the installation position.

The advantage of such a setting is that it is convenient to realize the rapid combination and disassembly of the locking rod 205, the matching holes 204 and the locking holes 206 by twisting the locking rod 205. Alternatively, the optional locking rods 205 are all cylindrical rubber rods, the matching holes 204 and the locking holes 206 are all smooth round holes, and the locking rods 205 are all coaxially detachably connected with the corresponding matching holes 204 and the locking holes 206 by tensioning matching. The advantage of such a setting is that it is convenient to realize the rapid combination and disassembly of the locking rod 205, the matching holes 204 and the locking holes 206 by axially applying force to press and pull the locking rod 205. Specifically speaking of the end cap 202, the end cap 202 is in an outer hexagonal shape and the outer end face is provided with a force application groove 203 for convenient holding as a force application point. Preferably, the force application groove 203 is a groove and a rod is extended and fixed between the inner walls. With such an arrangement, when it is necessary to turn the locking rod 205, the locking rod 205 can be smoothly turned by using a tool in cooperation with the end cap 202. At the same time, when it is necessary to hold, pull and press the locking rod 205, the locking rod 205 can be pulled and pressed by using the force application groove 203 as the force application point.

The positioning and installation strip 302 is fixed in the installation position by installing the connecting piece 304 through the connecting hole 305. The lower end of the connecting piece 304 should be inserted into the installation position to complete the firm fixation of the positioning and installation strip 302. At the same time, the connecting piece 304 should be inserted into the installation position until the upper end is lower than the hidden groove 303 to complete the hidden storage at the top. Then, the positioning and installation groove 301 of the decorative line body 1 and the positioning and installation strip 302 are horizontally slidably matched to realize the rapid positioning and combination of the decorative line body 1 and the positioning and installation strip 302. The positioning and combination method of the decorative line body 1 and the positioning and installation strip 302 is simple and easy to realize. At the same time, since the cross-sectional shapes of the positioning and installation strip 302 and the positioning and installation groove 301 are both dovetail The positioning and installation groove 301 and the positioning and installation strip 302 can be prevented from being separated from each other in other directions after being slidably matched in the horizontal direction, which further facilitates the rapid positioning and combination of the decorative line body 1 and the positioning and installation strip 302, avoids the misalignment in other directions after the decorative line body 1 and the positioning and installation strip 302 are positioned and combined in the horizontal direction, and also facilitates the combination and installation of the blocking and limiting components 2 from both sides. Specifically, in the combination and installation process of the blocking and limiting components 2, after the positioning and installation groove 301 of the decorative line body 1 and the positioning and installation strip 302 are slidably matched in the horizontal direction and are in place, the end of the positioning and installation groove 301 is blocked by attaching the side blocking piece 201 to the corresponding side end surface of the decorative line body 1, and then The matching hole 204 and the locking hole 206 are respectively coaxially aligned, and then the side baffle 201 can be quickly and detachably fixed to the side position of the decorative line body 1 by means of the locking rod 205 passing through the matching hole 204 horizontally and coaxially cooperating with the locking hole 206. The assembly method of the side baffle 201 at the side end position of the decorative line body 1 is simple and easy to operate, and then the side baffle 201 can be quickly assembled at the side end position of the decorative line body 1 to prevent the decorative line body 1 and the positioning installation strip 302 from being separated from each other. When the side baffle 201 needs to be removed later, it is only necessary to make the locking rod 205 disengage from the locking hole 206 and the matching hole 204 in turn, and then the locking rod 205 can be removed, and then the side baffle 201 can be detached from the side end position of the decorative line body 1.The side baffle 201 is easy to disassemble at the side end of the decorative line body 1, so that the decorative line body 1 and the positioning and mounting strip 302 can be separated from each other by lateral sliding after the side baffle 201 is removed and replaced and maintained.
