DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] In the related art, since the guide rails of the linkage door are usually profile structures, the two ends of the guide rail groove are open structures. If the operation is improper and the door body is pushed in the reverse direction, the rollers and other guide parts will be detached from the end opening structure of the guide rail groove, causing the linkage mechanism of the linkage belt to fail, and it will be difficult to push it back to its original position, requiring disassembly and maintenance.

[0032] Reference below Figure 5 to Figure 6 The anti-thrust mechanism according to the embodiment of the utility model is described.

[0033] like Figure 5 , Figure 6 As shown, according to the anti-back-thrust mechanism of the embodiment of the utility model, the anti-back-thrust mechanism is installed at the end of the guide rail body 100, and a guide groove 101 is provided on at least one side of the guide rail body 100. The anti-back-thrust mechanism includes a linkage pulley fixing member 200, which is arranged at the end of the guide rail body 100 and is provided with a linkage pulley 400. The linkage pulley fixing member 200 is provided with a blocking portion 210 extending into the guide groove 101. By setting the blocking portion 210, the guide members such as rollers can be blocked from detaching from the opening of the guide groove 101, which can prevent the sliding door from back-thrusting and improve the reliability of the use of the linkage door. The blocking portion 210 is located at the linkage pulley fixing member 200. When the linkage pulley fixing member 200 is installed, an anti-back-thrust structure can be formed at the same time, without the need to configure a blocking component separately, the structure is simpler, and the assembly is more convenient and quick.

[0034] Specifically, the guide rail body 100 is generally installed on the upper or lower part of the door body, or serves as the upper door frame or lower door frame of the door body. The guide rail body 100 is configured into three groups or more, which are connected through a linkage mechanism to achieve the linkage opening or closing of the door body. The linkage mechanism is a linkage belt linkage mechanism, which is configured with a linkage belt, a linkage belt fixing member, and a linkage belt pulley fixing member 200. The linkage belt fixing member is provided with guide members such as rollers. The guide member is placed in the guide groove 101 of the guide rail body 100 to achieve a guiding effect. The blocking part 210 partially or completely blocks the end opening of the guide groove 101 to form an anti-push back structure.

[0035] It should be noted that, in the utility model, the reverse push of the sliding door means that when the door body is in the folded position, the user pushes the door body to open in the wrong direction, or when the door body is in the unfolded position, the user pushes the door body to fold in the wrong direction.

[0036] like Figure 5 , Figure 6As shown, in some embodiments of the utility model, the blocking portion 210 is a concave arc structure, one end of the arc structure is connected to the groove wall of the guide groove 101, and the other end of the arc structure extends to the inside of the guide groove 101. The guide member sliding in the guide groove 101 is a roller. By setting the blocking portion 210 with a concave arc structure, it can better fit with the roller, the blocking effect is good, and the transition is smoother, thereby improving the smoothness of the movement of the door body.

[0037] Specifically, the arc structure is approximately 1 / 4 arc (or smaller), which can match one side of the roller to form a blocking structure. One end of the arc structure is connected to the groove wall of the guide groove 101 to form a smooth transition structure to reduce the occurrence of roller jumping.

[0038] It is conceivable that in some embodiments of the present invention, the blocking portion 210 may also be other structures. For example, when the guide member sliding in the guide groove 101 is a slider, the blocking surface of the blocking portion 210 may be a planar structure, and the blocking portion 210 may be set to a square shape, etc.

[0039] It is understandable that in some embodiments of the present invention, guide grooves 101 are provided on both sides of the guide rail body 100 , and blocking portions 210 are provided on both sides of the linkage pulley fixing member 200 to block the two guide grooves 101 respectively.

[0040] like Figure 5 , Figure 6 As shown, in some embodiments of the present invention, the linkage pulley fixing member 200 is provided with an insertion portion 220, and the guide rail main body 100 is provided with a first insertion groove 102 that cooperates with the insertion portion 220, and a fastening mechanism is provided between the linkage pulley fixing member 200 and the guide rail main body 100 to fasten the insertion portion 220 into the first insertion groove 102, thereby fixing the linkage pulley fixing member 200 and the guide rail main body 100.

[0041] Specifically, Figure 6 As shown, the first insertion slot 102 extends along the length direction of the guide rail body 100 and forms an opening at the end of the guide rail body 100. The insertion portion 220 of the linkage pulley fixing member 200 can be inserted into the first insertion slot 102 from the end of the guide rail body 100. The fastening mechanism fastens the insertion portion 220 into the first insertion slot 102, thereby installing the linkage pulley fixing member 200 to the end of the guide rail body 100.

[0042] like Figure 5 , Figure 6As shown, in some embodiments of the present invention, the insertion portion 220 is a protruding structure located on both sides of the linkage pulley fixing member 200, and a mounting groove for the linkage pulley fixing member 200 to be installed is provided on the guide rail body 100, and two convex ridges are provided on the groove walls on both sides of the mounting groove to form the above-mentioned first insertion groove 102.

[0043] like Figure 5 , Figure 6 As shown, in some embodiments of the present invention, the fastening mechanism includes a fastening screw 230, and the linkage pulley fixing member 200 is provided with a threaded through hole 231. The fastening screw 230 can be screwed into the threaded through hole 231 and abut against the bottom of the first insertion slot 102, reacting to the linkage pulley fixing member 200, so that it is squeezed into the first insertion slot 102.

[0044] Specifically, the threaded through hole 231 extends from top to bottom and penetrates the linkage pulley fixing member 200. When the fastening screw 230 is tightened, the lower end of the fastening screw 230 is pressed against the bottom of the first insertion slot 102, generating an upward reaction force on the linkage pulley fixing member 200, thereby squeezing the insertion portion 220 of the linkage pulley fixing member 200 into the first insertion slot 102.

[0045] It is conceivable that in some embodiments of the present invention, the linkage pulley fixing component 200 can also be directly installed to the guide rail body 100 through fasteners, such as providing a threaded hole on the guide rail body 100, providing a through hole on the linkage pulley fixing component 200, and screwing the screw through the through hole into the threaded hole, and the linkage pulley fixing component 200 can also be fixed to the guide rail body 100.

[0046] Reference Figures 1 to 4 According to the second aspect of the present invention, the movable door guide rail assembly includes a guide rail body 100 and an anti-thrust mechanism of any one of the first aspects of the present invention installed on the guide rail body 100. By adopting the above-mentioned anti-thrust mechanism, the sliding door installed with the movable door guide rail assembly can be prevented from being pushed back, thereby improving the reliability of the use of the linkage door.

[0047] like Figures 1 to 4 As shown, in some embodiments of the present invention, a panel 110 is disposed at the end of the guide rail body 100 to cover the internal structure of the end of the guide rail body 100 .

[0048] Specifically, the guide rail body 100 is a profile such as an aluminum profile, and has a plurality of opening structures at the end and a plurality of mounting components. By configuring the panel 110, the end of the guide rail body 100 can be shielded to improve the aesthetics and have a certain dustproof effect.

[0049] It is conceivable that, in some embodiments of the present invention, the panel 110 can be detachably mounted on the end of the linkage pulley fixing member 200 to facilitate assembly and maintenance.

[0050] Specifically, after the linkage pulley fixing member 200 is installed at the end of the guide rail body 100, the end of the linkage pulley fixing member 200 is located at the end surface of the guide rail body 100, and the panel 110 is detachably installed at the end of the linkage pulley fixing member 200, so that the end of the guide rail body 100 can be covered.

[0051] It can be understood that in some embodiments of the present invention, the panel 110 can also be configured to be detachably installed on the end of the guide rail body 100, such as the panel 110 can be detachably installed on the end of the guide rail body 100 through a magnetic structure, a screw mechanism, a snap mechanism, etc.

[0052] like Figure 5 , Figure 6 As shown, in some embodiments of the present invention, a magnetic member 120 is provided at the end of the linkage pulley fixing member 200, and the panel 110 is partially or entirely made of magnetic material or the panel 110 is provided with a magnetic attraction portion, and the panel 110 is installed to the end of the linkage pulley fixing member 200 by magnetic attraction.

[0053] It is conceivable that in some embodiments of the present invention, the panel 110 may also be mounted to the end of the linkage pulley fixing member 200 by a snap mechanism.

[0054] like Figure 5 , Figure 6 As shown, in some embodiments of the present invention, a second insertion slot 103 is provided at the end of the linkage pulley fixing member 200, and the magnetic member 120 is configured to have a shape matching the second insertion slot 103 so that the magnetic member 120 can be inserted into the second insertion slot 103, thereby fixing the magnetic member 120.

[0055] Specifically, the cross section of the second insertion slot 103 is an inverted T-shaped structure, and the outer contour of the magnetic member 120 corresponds thereto, so that the magnetic member 120 is now disengaged outwardly along the length direction of the guide rail body 100 .

[0056] It is understandable that in some embodiments of the present invention, the magnetic member 120 and the second insertion slot 103 may be an interference fit structure, or a fastener is configured between the magnetic member 120 and the end of the linkage pulley fixing member 200 to position the magnetic member 120 in the second insertion slot 103.

[0057] Specifically, a threaded hole is set at the magnetic part 120 and a fastening screw is configured. The threaded hole is a through hole. After the fastening screw is screwed into the threaded hole and tightened, the end of the fastening screw can be pressed against the slot wall of the second insertion slot 103, thereby squeezing the magnetic part 120 into the second insertion slot 103.

[0058] It is understandable that in some embodiments of the present invention, the magnetic member 120 may also be fixed to the end of the linkage pulley fixing member 200 by gluing, screwing, etc., which will not be described in detail herein.

[0059] like Figure 4 , Figure 5 As shown, in some embodiments of the present invention, a positioning groove 104 is provided at the end of the guide rail body 100, and the panel 110 is provided with a positioning portion 130 that can be inserted into the positioning groove 104. When the panel 110 is installed to the end of the guide rail body 100, the positioning portion 130 is inserted into the positioning groove 104 to locate the position of the panel 110.

[0060] Specifically, in this embodiment, the panel 110 is mounted to the end of the linkage pulley fixing member 200 by magnetic attraction, and the positioning structure composed of the positioning portion 130 and the positioning groove 104 can stably mount the panel 110 on the end of the guide rail body 100 .

[0061] It is understandable that in some embodiments of the present invention, multiple magnetic structures at different positions may be configured to improve the stability of the installation of the panel 110 .

[0062] Of course, the invention of the present invention is not limited to the above-mentioned implementation modes. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
