Description

Technical Field

[0001] The utility model relates to the field of linked door equipment, in particular to a linkage wheel for a linked door and a linked door structure. Background Art

[0002] The linked door is divided into two types: synchronous same-direction linkage and synchronous reverse linkage. That is, when opening or closing the door, any one of the doors can be pushed arbitrarily, and the other door will follow the linkage, realizing the function of opening and closing the two doors simultaneously, making the change of space more rapid. With a gentle push and pull, the sliding door can be opened or closed.

[0003] The width of the opened linked sliding door can be twice the width of the door leaf, and there are no visible components on the opened ground, without damaging the overall decoration effect of the ground. The opened doors are folded together, showing two-thirds of the space, which is convenient for walking and carrying large items. It is suitable for kitchens, studies, shower rooms, etc.

[0004] However, the current linked door structure is prone to problems such as unsmooth opening and closing during use. The main reason is that the existing steel wire anti-detachment pieces mostly use the downward pressure method to limit the transmission parts. During the continuous pushing and pulling of the linked door, the steel wire anti-detachment pieces will constantly abrade the steel wire, resulting in the breakage of the transmission parts after several months of use. And it is relatively difficult to replace the steel wire, which requires disassembling and reinstalling the entire linked sliding door accessories, greatly reducing the user experience. Summary of the Utility Model

[0043] To make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0044] As Figure 1 and Figure 2 shown, a linkage wheel for a linkage door provided by an embodiment of the present invention includes a wheel seat 1, a pulley 2, a transmission part 3, and a limiting part 4. Among them, the wheel seat 1 is rotatably installed in the mounting groove 101 of the suspension rail 10 of the linkage door to rotate from the first state (as Figure 3 shown) to the second state (as Figure 3Aas shown). Moreover, the wheel seat 1 is rotatably mounted in the mounting groove 101 so as to be flipped from a second state (such as Figure 3A as shown) to a third state (such as Figure 4 as shown). The pulley 2 is rotatably mounted on the surface of the wheel seat 1, and a transmission member 3 (for example, a steel wire rope) is wound around the pulley 2. The limiting member 4 is mounted on the surface of the wheel seat 1 and is located on one side of the pulley 2 to perform sliding limitation on the transmission member 3 through the limiting hole 41, so as to prevent the transmission member 3 from disengaging from the pulley 2 and reduce the friction on the transmission member 3.

[0045] Such as Figure 2 as shown, in this embodiment, the wheel seat 1 is generally in a rectangular sheet-like structure. An anti-disengagement protrusion 11 is provided at one end of the wheel seat 1 close to the pulley 2. Moreover, with reference to Figure 3 as shown, a mounting groove 101 is formed in the suspension rail 10 along the length direction. Both sides of the top of the mounting groove 101 extend inward respectively to form flanges 102.

[0046] Such as Figure 3 as shown, in the first state, the wheel seat 1 is placed in the mounting groove 101 and can move freely. Specifically, in this state, the wheel seat 1 is perpendicular to the suspension rail 10 and the thickness direction of the wheel seat is parallel to the width direction of the mounting groove (i.e., the direction indicated by the double-headed arrow in Figure 3 ). Since there is no limiting effect in any direction, the wheel seat 1 can move freely in the mounting groove 101.

[0047] Moreover, in this embodiment, the maximum distance from one side of the pulley 1 to the other side of the wheel seat 1 (i.e., the maximum width in the width direction of the mounting groove) is smaller than the width of the notch of the mounting groove 101, so that when the width direction of the wheel seat 1 is parallel to the length direction of the guide rail, the wheel seat 1 can be inserted into the mounting groove 101 through the suspension rail 10. In addition, the width of the wheel seat 1 is smaller than the width of the notch of the mounting groove 101, so that when the width direction of the wheel seat 1 is perpendicular to the length direction of the suspension rail, the wheel seat 1 can be placed into the mounting groove 101.

[0048] Such as Figure 3A as shown, in the second state, one end of the wheel seat 1 is engaged with the mounting groove 101 to limit the movement of one end of the wheel seat 1 in the height direction of the suspension rail 10. Specifically, in this state, the wheel seat 1 is perpendicular to the suspension rail 10, and the width direction of the wheel seat 1 is parallel to the width direction of the mounting groove (i.e., the direction indicated by the double-headed arrow in Figure 3A ), so that the anti-disengagement protrusion 11 is located in the notch of the mounting groove 101 and abuts against the flange 102, thereby performing movement limitation on one end of the wheel seat 1 in the height direction of the suspension rail 10.

[0049] Such as Figure 4As shown in the figure, in the third state, the wheel seat 1 is parallel to the suspension rail 10, and the anti - detachment protrusion 11 is engaged with the installation groove 101 to limit one end of the wheel seat 1 from disengaging from the installation groove 101. Moreover, in this embodiment, to improve the stability of the installation of the wheel seat 1, in the third state, the other end of the wheel seat 1 is also engaged with the installation groove 101 to limit the movement of the other end of the wheel seat 1 in the height direction of the suspension rail 10.

[0050] Specifically, in this embodiment, preferably, the upper surface of the other end of the wheel seat 1 is recessed inward to form a recessed portion 110. And a limiting plate 5 is rotatably installed in the recessed portion 110 around the direction perpendicular to the surface of the wheel seat 1, so that the limiting plate 5 can be switched between the avoidance state and the limiting state. Specifically, during the process of the wheel seat 1 changing from the first state to the third state, the limiting plate 5 is always in the avoidance state. At this time, the edge of the limiting plate 5 does not protrude from both sides of the wheel seat, thus avoiding interference with the rotation of the wheel seat 1. When the wheel seat 1 is switched to the third state, then rotate the limiting plate 5 so that the limiting plate 5 is switched from the avoidance state to the limiting state. At this time, the edge of the limiting plate 5 protrudes from both sides of the wheel seat (as shown in the state in Figure 1 the figure), and abuts against the flanging 102, thereby limiting the relative position of the wheel seat 1 and the suspension rail 10 in the height direction of the suspension rail.

[0051] It can be understood that in this embodiment, in the third state, on the one hand, the mutual abutment of the anti - detachment protrusion 11 and the flanging 102 can limit one end of the wheel seat 1 in the height direction; on the other hand, the mutual abutment of the limiting plate 5 and the flanging 102 can limit the other end of the wheel seat 1 in the height direction, thereby ensuring the overall stability of the wheel seat 1.

[0052] As Figure 5 shown, in another embodiment, preferably, a plug pin 6 can also be provided at the end of the wheel seat 1 far from the pulley 2. Correspondingly, a jack 103 is provided at a position on the inner wall of the installation groove 101 corresponding to the plug pin 6. Thus, by engaging or separating the plug pin 6 and the jack 103, the relative movement of the wheel seat 1 and the suspension rail 10 in the length direction and height direction of the suspension rail can be limited or the movement limit can be released.

[0053] As Figure 2 shown, in this embodiment, the pulley 2 is rotatably installed on the lower surface of the wheel seat 1 around the direction perpendicular to the lower surface of the wheel seat 1. Specifically, an installation hole 13 is provided at one end of the wheel seat 1 close to the anti - detachment protrusion 11. A rotating shaft 21 is installed in the installation hole 13, and the pulley 2 is rotatably installed on the rotating shaft 21, and a washer 22 is provided between the pulley 2 and the wheel seat 1. Correspondingly, the transmission member 3 is wound around the pulley 2 for power transmission.

[0054] As Figure 2As shown, in this embodiment, the limiting member 4 is disposed on the lower surface of the wheel seat 1 and at one end of the pulley 2. Moreover, limiting portions 41 are provided on both sides of the limiting member 4, and the limiting portions 41 are matched with the transmission member 3 to slidably limit the transmission member 3. Specifically, one end of the limiting member 4 close to the pulley is an arc portion 42, and the arc portion 42 is matched with the pulley 2 so that the limiting portion 41 can be adjacent to the pulley 2, which is beneficial to improving the limiting effect of the limiting portion 41 on the transmission member 3.

[0055] Referring to Figure 2 As shown, in the above embodiment, preferably, limiting slots 14 are provided on both sides of the wheel seat 1, and limiting protrusions 43 extend toward the wheel seat 1 on the surface of the limiting member 4 facing the wheel seat 1. When the limiting member 4 is installed on the surface of the wheel seat 1, the limiting protrusions 43 are engaged with the limiting slots 14 to limit the relative positions of the wheel seat 1 and the limiting member 4. Moreover, it can also play a certain role in installation positioning, facilitating the assembly of the limiting member 4 and the wheel seat 1.

[0056] In the above embodiment, preferably, limiting columns 44 are formed on both sides of the limiting member, and a limiting hole 41 is provided at the center of the limiting column 44. Thus, the transmission member 3 is passed through the limiting hole 41 of the limiting column. More preferably, the limiting member 4 and the limiting column 42 are integrally formed to ensure the structural strength.

[0057] As Figure 6 As shown, an embodiment of the present utility model further provides a linkage door structure 200, which includes the above linkage wheel 100, and may also include structural members such as a hanging rail 10, a fixed fan 20, and a movable fan 30, which will not be specifically described herein.

[0058] In summary, a linkage wheel and a linkage door structure for a linkage door provided by an embodiment of the present utility model have the following beneficial effects:

[0059] (1) By disposing the limiting member 4 on the wheel seat 1 and at one end of the pulley 2, the limiting holes 41 on both sides of the limiting member 4 are used to slidably limit the transmission member, which can not only prevent the transmission member from disengaging from the pulley, but also greatly reduce the friction with the transmission member, improving the safety of the transmission member during use.

[0060] (2) The wheel seat 1 can be very conveniently installed on the hanging rail 10 in a flipping manner, simplifying the cumbersome steps of traditional pulley installation and improving the installation efficiency. Moreover, by using the anti-disengagement protrusion and the limiting plate on the wheel seat 1, the positioning of the wheel seat 1 and the hanging rail 10 is realized, ensuring the stability of the installation.

[0061] (3) The arc portion 42 on the limiting member 4 can match with the pulley 2, so that it can be adjacent to the pulley 2, which is beneficial to improving the limiting effect of the limiting portion 41 on the transmission member 3. Moreover, the limiting protrusion 43 on the limiting member 4 can be engaged with the limiting card slots 14 on both sides of the wheel seat 1, so as to install, position and limit-fix the limiting member 4.
