Embodiment one:

as shown in fig. 1 and 2, the sliding rail 100 comprises at least two profiles 1 and corner connection structures. Wherein the corner connection is for splicing at least two profiles 1 comprising a connecting piece 2 and a fastener 3.

As shown in fig. 1, 2, 3 and 10, each profile 1 is provided with a slideway extending in the direction of extension thereof. The connecting ends of the profiles 1 are provided with splicing angles 11, and at least two through holes 12 are arranged on the profiles 1 along the extending direction. Each profile 1 is provided with a first cavity 13 adapted for the insertion of each connecting portion 211. The sections 1 are spliced to form the sliding rail 100 and then have a corner at the spliced position. The joint end of each section bar 1 is provided with the splicing angle 11, so that the splicing angles 11 of each section bar 1 are spliced together to form the sliding rail 100 with the corner.

In the present embodiment, as shown in fig. 1, 2, 3 and 10, the profile 1 is provided with two, and the end surfaces of the connection ends of the respective profiles 1 are inclined so that the connection ends of the profiles 1 form a sharp-angled joint angle 11, and the tip of the joint angle 11 forms a tip 14 of the joint angle. Two through holes 12 are arranged on each section bar 1. In particular, as shown in fig. 10, the profile 1 is provided with a first cavity 13 extending along its extension. The first cavity 13 penetrates through the end surfaces of the two ends of the profile 1, and the bottom wall is provided with a first opening 131 and two U-shaped grooves 132 with upward openings. Both the two U-shaped grooves 132 and the first opening 131 extend along the extending direction of the profile 1, and the first opening 131 is clamped between the two U-shaped grooves 132. The middle part of the top wall of the profile 1 is also provided with a first groove 133 recessed downwards, the first groove 133 extending in the direction of extension of the profile 1. Two through holes 12 are provided at the bottom of the first groove 133. In this embodiment, the first cavity 13 or the first groove 133 on each profile 1 forms a slideway.

As shown in fig. 4, 5 and 6, the connecting members 2 are provided with connecting portions 211 which are equal in number and correspond one to the profiles 1. Each connecting portion 211 is provided with mounting holes 2112 which are equal in number and one-to-one correspondence to the through holes 12 in the corresponding profile 1, and in this embodiment, two mounting holes 2112 are provided. At least one installation hole 2112 on at least one connecting portion 211 forms an eccentric hole, and the distance from the center of the eccentric hole to the top end 14 of the splicing angle of the corresponding profile 1 is smaller than the distance from the center of the through hole 12 corresponding to the eccentric hole to the top end 14 of the splicing angle of the corresponding profile 1. That is, the eccentric hole is a hole eccentrically provided to the corresponding through hole 12, and the eccentric hole is closer to the tip 14 of the splicing angle of the corresponding profile 1 than the corresponding through hole 12. When the profile 1 and the connecting portion 211 are assembled in place, since the eccentric hole and the corresponding through hole 12 are eccentrically arranged, the fastener 3 will abut against the wall of the through hole 12 corresponding to the eccentric hole to push against the corresponding profile 1 when locked with the eccentric hole.

Preferably, all the mounting holes 2112 on at least one connection portion 211 form eccentric holes; that is, when the profile 1 and the connection portion 211 are assembled in place, all the installation holes 2112 of at least one connection portion 211 are eccentrically disposed from the through holes 12 of the corresponding profile 1, forming eccentric holes. When the corresponding section bar 1 is fixedly connected with the connecting part 211, each fastener 3 can extrude the corresponding section bar 1, so that the section bar 1 is tightly attached to the rest section bars 1, and a gap is not easy to generate at the splicing position. In this embodiment, the two mounting holes 2112 on each connecting portion 211 form eccentric holes, and each section bar 1 is extruded by the fastener 3 so that the top end 14 of the splicing angle of the other section bar 1 is close to the top end 14 of the splicing angle of the other section bar 1, and a gap is not easy to generate at the splicing position.

Further, as shown in fig. 4, the connector 2 is provided with supporting portions 223, and the number of the supporting portions 223 is the same as that of the connecting portions 211 and corresponds to one. As shown in fig. 10, the first cavities 13 of each profile 1 are suitable for each connecting portion 211 to be inserted, when each connecting portion 211 is inserted into the corresponding first cavity 13, each supporting portion 223 abuts against the cavity wall of the corresponding first cavity 13 facing the through hole 12, so that the connecting piece 2 is supported to enable the fastener 3 to be better installed when being locked.

Specifically, as shown in fig. 4, the connector 2 includes a connector body 21 and a support 22. As shown in fig. 5 and 6, each of the connection portions 211 is provided on the connector body 21, and the support portion 223 is provided on the support 22. The number of the supporting pieces 22 is the same as the number of the connection portions 211 and detachably connected to the connection portions 211. The support 22 is further provided with a mounting portion 221 and a clamping portion 222. The mounting portion 221 is seated on a surface of the corresponding connection portion 211 facing the corresponding through hole 12, and is provided with a positioning column 2211 extending in a direction away from the corresponding through hole 12. Each support portion 223 is fixedly connected to each mounting portion 221. The engaging portion 222 extends in a direction away from the through hole 12, and engages with the corresponding connecting portion 211 in a surface away from the through hole 12. Each connecting portion 211 is provided with a positioning hole 2111 or a positioning groove which is in plug-in fit with the positioning column 2211 on the corresponding mounting portion 221. At least two positioning holes 2111 or positioning grooves are provided on each connecting portion 211, and are arranged along the extending direction corresponding to the connecting portion 211. Through the spliced cooperation of the positioning column 2211 and the positioning hole 2111 or the positioning groove and the surface clamped cooperation of the clamping part 222 and the connecting part 211 deviating from the through hole 12, the stable installation of the connecting part 211 is realized, the connecting part 211 cannot easily move along all directions, and the disassembly is more convenient. The positioning holes 2111 or the positioning slots are at least two, and are arranged along the extending direction of the connecting portion 211, so that both ends of the supporting member 22 are positioned and are not easy to shake, and the clamping portion 222 is convenient to be matched with the connecting portion 211 smoothly.

In practical use, since the connection portion 211 is required to be provided with the mounting hole 2112, a material having a high strength such as stainless steel is generally used for the purpose of increasing the strength. The support piece 22 is only used for supporting, and the connecting piece body 21 and the support piece 22 are detached, so that the support piece 22 can be made of other materials with lower cost, the material consumption of the connecting piece body 21 is reduced, and the cost is saved.

In this embodiment, as shown in fig. 5, two connection portions 211 are provided, each connection portion 211 is a plate-shaped body, and one ends of the two connection portions 211 are fixedly connected to form the connector body 21.

The second screw hole 2113 is located in the middle of the connecting portion 211 and between the two mounting holes 2112, and the two mounting holes 2112 are located between the two positioning holes 2111. Two notches 2114 are further formed in the middle of each connecting portion 211, the two notches 2114 penetrate through the notches 2114 on the upper surface and the lower surface of the connecting portion 211 and are respectively opened to the front surface and the rear surface of each connecting portion 211, and the second threaded hole 2113 is further located between the two notches 2114.

As shown in fig. 6, the mounting portion 221 of each support 22 is a plate-like body, and the mounting portion 221 is provided with positioning posts 2211, two first through holes 2212, and two second through holes 2213 arranged along the extending direction thereof. The second through holes 2213 are located between the two first through holes 2212, and the two first through holes 2212 are located between the two positioning posts 2211.

As shown in fig. 6 and 10, the engaging portion 222 is a two-jaw member fixedly coupled to the mounting portion 221. The two jaws are fixedly connected with the mounting part 221 at positions corresponding to the two notches 2114 of the connecting part 211.

As shown in fig. 6 and 10, in the present embodiment, the supporting portion 223 includes two supporting legs 2231, and the two supporting legs 2231 are fixedly connected to the mounting portion 221 at positions corresponding to the two notches 2114 of the connecting portion 211. And, two jaws are located between the two supporting legs 2231.

When the mounting portion 221 is located on the surface of the corresponding connecting portion 211 facing the corresponding through hole 12, the two first through holes 2212 are respectively correspondingly communicated with the two mounting holes 2112 on the corresponding connecting portion 211, the second through holes 2213 are correspondingly communicated with the second threaded holes 2113, and the two positioning posts 2211 are in plug-in fit with the two positioning holes 2111. The two jaws of the clamping portion 222 penetrate through the corresponding two notches 2114 to be in clamping fit with the surface of the connecting portion 211, which faces away from the through hole 12. The two supporting legs 2231 penetrate through the two corresponding notches 2114 and respectively abut against the bottom walls of the two U-shaped grooves 132 on the profile 1.

As shown in fig. 2 and 9, the number of the fasteners 3 is equal to and corresponds to the number of the mounting holes 2112 one by one. The fastener 3 is adapted to penetrate through the through hole 12 and lock with the corresponding mounting hole 2112 so as to fix each connecting portion 211 to each section bar 1, and the fastener 3 corresponding to the eccentric hole presses the corresponding section bar 1 to make the top end 14 of the splicing angle of the corresponding section bar 1 close to the top ends 14 of the splicing angles of the other section bars 1. The fastener 3 includes a screw portion 31 and a pressing portion 32 integrally connected. Each pressing portion 32 has a truncated cone shape. Each screw connection portion 31 is screw-connected with the corresponding mounting hole 2112, each pressing portion 32 presses the corresponding section bar 1, so that each connecting portion 211 is fixedly connected with the corresponding section bar 1, and the conical surface of the pressing portion 32 corresponding to the eccentric hole also presses the corresponding section bar 1 to enable the top end of the splicing angle of the corresponding section bar 1 to be close to the top end 14 of the splicing angle of the other section bars 1. In this embodiment, the fastener 3 employs a countersunk head screw 10. The slide rail 100 of the present embodiment is mounted:

as shown in fig. 1 to 10, first, the mounting portion 221 of each support 22 is seated on each connection portion 211, and the positioning posts 2211 of each support 22 are inserted into the positioning holes 2111, so that the engagement portions 222 are engaged with the connection portions 211, thereby mounting the connection portions 211. Then, the two connecting portions 211 are inserted into the first cavity 13 from the end portions of the connecting ends of the profiles 1, respectively, and the end surfaces of the connecting ends of the two profiles 1 are abutted. Thereafter, the fastener 3 is inserted into the mounting hole 2112 of the connecting portion 211 through the through hole 12 of each profile 1 and screwed into the mounting hole 2112, thereby fixing the profile 1 and each connecting portion 211 together, and completing the installation.

It should be understood that in the remaining embodiments, if only a part of the mounting hole 2112 on the profile 1 forms an eccentric hole, the eccentric hole should be pre-installed first, then the fastener 3 should be pre-installed after aligning the remaining mounting hole 2112 on the profile 1 with the through hole 12, then the fastener 3 corresponding to the eccentric hole should be locked first, and then the remaining fastener 3 should be locked.

In this embodiment, as shown in fig. 9, each profile 1 is fixedly connected with each connecting portion 211 on the connecting member 2 by the fastener 3 to achieve splicing. Since the at least one mounting hole 2112 on the at least one connecting portion 211 forms an eccentric hole, and the distance from the center of the eccentric hole to the top end 14 of the splicing angle of the corresponding section bar 1 is smaller than the distance from the center of the through hole corresponding to the eccentric hole to the top end 14 of the splicing angle of the corresponding section bar 1, when the section bar 1 and the connecting portion 211 are assembled in place, the eccentric hole and the corresponding through hole 12 are eccentrically misplaced. When the fastener 3 penetrates through the through hole 12 and is locked with the eccentric hole, the fastener 3 corresponding to the eccentric hole can extrude the corresponding section bar 1 to push the corresponding section bar to the top end 14 close to the splicing angle of the other section bars 1 so as to be tightly attached to the other section bars 1, and the extrusion force of the fastener 3 makes the section bar 1 not easy to generate gaps at the splicing position. At least two through holes 12 are arranged on the section bar 1 and are distributed along the extending direction; so that each profile 1 is fixedly connected with the corresponding connecting part 211 by at least two fastening pieces 3 distributed along the extending direction of the profile 1, compared with the condition that only one fastening piece 3 is fixedly connected, when the profile 1 is extruded by the fastening pieces 3, the installation is not influenced by the change of the included angle between each profile 1 caused by extrusion force due to the mutual limitation of a plurality of fastening pieces 3. The pressing portion 32 of the fastener 3 in the present embodiment is formed in a truncated cone shape, so that the profile 1 corresponding to the eccentric hole can be better pressed during installation by the inclined surface fitting, and the connecting portions 211 can be fastened to the corresponding profile 1 when the pressing portion 32 presses the corresponding profile 1.

The limiting block 9 is fixedly connected with one of the connecting parts 211 of the corner connecting structure or one of the profiles 1, so that an object positioned in the corresponding slideway cannot continue sliding after abutting against the limiting block 9. The extension direction of the stopper 9 is the same as the extension direction of the corresponding slide, and is provided in the bar-shaped hole 91 extending along the extension direction. The limiting block 9 is fixedly connected with the corresponding connecting part 211 or the profile 1 through the screw 10 penetrating through the strip-shaped hole 91.

If the limiting block is fixedly connected with the profile, the connecting portion 211 and the supporting member 22 in the first embodiment may not be provided with the second threaded hole 2113 and the second through hole 2213. In actual use, the limiting block 9 is arranged on one side of the connecting portion 211 away from the mounting portion 221, and is fixed by passing the screw 10 through the strip-shaped hole 91 and being screwed with the second threaded hole 2113.

The sliding rail of the present embodiment has all the beneficial effects of the sliding rail 100 in the first embodiment, and the limiting block 9 is provided to limit the object in the sliding rail.

Embodiment III:

as shown in fig. 11 and 13, the present embodiment provides a shower room including a fixed door 4, a movable door 5, an upper slide rail 6, a lower slide rail 7, and both side frames 8. The upper rail 6 and/or the lower rail 7 are the rails 100 of the first or second embodiment.

As shown in fig. 11 to 14, in the present embodiment, the slide rail 6 is described by taking the slide rail 100 of the second embodiment as an example. The first cavities 13 of the profiles 1 in the upper slide rail 6 are sequentially communicated to form a slide way. The upper slide rail 6 is provided with three section bars 1, and two ends of the middle section bar 1 are respectively spliced with other two section bars 1 through corner connecting structures.

As shown in fig. 11, the lower rail 7 is installed on the ground, and is provided with a slide rail extending in the extending direction thereof and opening toward the upper rail 6.

As shown in fig. 11, the two side frames 8 extend in the vertical direction and are respectively fixed to the wall surfaces. Two ends of the two side frames 8 are fixedly connected with the end parts of the same end of the upper slide rail 6 and the lower slide rail 7 respectively.

As shown in fig. 11, the upper and lower ends of the fixed door 4 are respectively mounted on the slide rails of the upper slide rail 6 and the lower slide rail 7. In this embodiment, two fixed doors 4 are provided.

As shown in fig. 11, the sliding door 5 is slidably connected or hinged with the upper slide rail 6 and the lower slide rail 7. In this embodiment, the movable door 5 is hinged with an upper slide rail 6 and a lower slide rail 7.

As shown in fig. 11, 13 and 14, the limiting block is used for propping against the fixed door 4 to limit the fixed door 4 to slide along the upper slide rail 6 and the lower slide rail 7. Due to the two fixed doors 4, the limiting blocks 9 on the two corner connecting parts respectively prop against one side of the two fixed doors 4 close to the movable door 5.

When the shower stall of the present embodiment is installed, as shown in fig. 11 to 14, the lower rail 7 is first fixed to the floor. Then, the lower ends of the two side frames 8 are respectively fixedly connected with the two ends of the lower slide rail 7, and the two side frames 8 are respectively fixed on the wall surface. Then, both ends of the upper slide rail 6 are fixedly connected with the upper ends of the two side frames 8. Then, both ends of the fixed door 4 are respectively installed in the sliding grooves of the upper sliding rail 6 and the lower sliding rail 7. The limiting block 9 is placed in the sliding groove, the position is adjusted to enable the limiting block 9 to prop against the fixed door 4, and the limiting block 9 is fixedly connected with one side, away from the mounting portion, of the connecting portion 211 through the screw 10. Then, the hinged installation of the movable door 5 with the upper slide rail 6 and the lower slide rail 7 is completed.

It should be appreciated that in the remaining embodiments, if the lower slide rail 7 employs the slide rail 100 of the first embodiment, the first groove 133 forms a slideway for the lower slide rail 7.

The shower room of the present embodiment adopts the slide rail 100 of the second embodiment, and has all the advantages of the slide rail 100. The fixed door 4 is propped against by the limiting block 9 to limit the fixed door 4 to slide along the upper sliding rail 6 and the lower sliding rail 7, so that the fixed door 4 is prevented from running due to vibration caused by opening and closing the door of a shower room. Since the strip-shaped hole 91 extends along the extending direction of the corresponding profile 1, the locking position of the limiting block 9 and the connecting part 211 can be adjusted to adapt to the fixed doors 4 with different sizes, and the application range is wider.

The foregoing description of the embodiments and description is presented to illustrate the scope of the utility model, but is not to be construed as limiting the scope of the utility model. Modifications, equivalents, and other improvements to the embodiments of the utility model or portions of the features disclosed herein, as may occur to persons skilled in the art upon use of the utility model or the teachings of the embodiments, are intended to be included within the scope of the utility model, as may be desired by persons skilled in the art from a logical analysis, reasoning, or limited testing, in combination with the common general knowledge and/or knowledge of the prior art.
