[0055] In view of this, the present application provides a triple moving mechanism and a triple moving door. Figures 1 to 8 The embodiments of the triple moving mechanism provided by the present application are as follows, Figures 9 to 12 The embodiments of the triple moving door provided by the present application are as follows.

[0056] Please refer to Figures 1 to 3The triple moving mechanism 100 comprises a guide rail part 1, a sliding assembly and a linkage mechanism 3, the guide rail part 1 is used for being mounted on the upper part of the door frame 300, the sliding assembly comprises a first moving seat 21 and two second moving seats 22 arranged on the longitudinal two sides of the first moving seat 21, the lower ends of the first moving seat 21 and the two second moving seats 22 are used for clamping the door leaf 200, the first moving seat 21 and the two second moving seats 22 are slidably arranged in the guide rail part 1 along the transverse direction, the linkage mechanism 3 comprises two friction wheels 31 arranged on the first moving seat 21 along the transverse direction and linked with each other, each friction wheel 31 rotates along an axis extending in the up-down direction, each friction wheel 31 can be frictionally connected with the opposite side of the two second moving seats 22, so that the first moving seat 21 can be linked with any one of the second moving seats 22 to slide.

[0057] In the technical scheme of the present application, the friction wheel 31 is arranged on the first moving seat 21, when the friction wheel 31 is frictionally connected with the second moving seat 22, the linkage sliding of the second moving seat 22 and the first moving seat 21 can be realized, when in the closed state, the first moving seat 21 and the two second moving seats 22 can overlap in the longitudinal direction, so that the access space is maximized, at this time, each friction wheel 31 is connected with the two second moving seats 22 at the same time, in the process of pushing and pulling sliding, any driving of the second moving seat 22 can drive the friction wheel 31 to rotate, at this time, the first moving seat 21 is in the driven state and moves together, so that the linkage movement is realized by relying on the friction driving, that is, in the structure, the first moving seat 21 and the two second moving seats 22 can realize bidirectional movement, the linkage of the first moving seat 21 and any one of the second moving seats 22 can be realized, and the linkage of the three moving seats can also be realized, so that the user can access from any side, and the flexibility is high.

[0058] In order to ensure the matching effect of the friction wheel 31 and the second moving seat 22, please refer to Figure 4 and Figure 6 The side of each second moving seat 22 facing the friction wheel 31 is formed with a matching inclined surface 221, the matching inclined surface 221 is arranged to be inclined from top to bottom towards the friction wheel 31, the lower end of the friction wheel 31 is arranged to be tapered downward to form an annular friction surface 312, the annular friction surface 312 can be tightly matched with the matching inclined surface 221. That is, the friction wheel 31 can be matched with the inclined surface of any second moving seat 22, which ensures a large friction contact area and improves the stability of linkage friction.

[0059] It can be understood that the entire side of each second moving seat 22 and the friction wheel 31 can be arranged to be inclined, or part of the vertical section can be reserved, and the present application does not limit the comparison.

[0060] In order to improve the friction, in an embodiment, the annular friction surface 312 is provided with an annular groove, and a rubber ring 34 is installed in the annular groove. The material of the rubber ring 34 can be rubber or other materials with good compression deformation performance. During cooperation, the rubber ring 34 can be deformed by compression, so as to ensure that the annular friction surface 312 is attached to the cooperating inclined surface 221, improve the friction, and ensure the effect of friction linkage. If the rubber ring 34 is worn after long-term use, it only needs to be replaced.

[0061] During the pushing and pulling process, especially during the door closing action, each friction wheel 31 is abutted and cooperated with the two second moving seats 22 away from each other. At this time, it is necessary to ensure the good linkage effect of the two friction wheels 31, so that when any moving seat is pushed, the synchronous rotation of the two friction wheels 31 can drive the movement of the other moving seats. For this purpose, in the embodiment of the application, please refer to Figures 5 to 6 The side of the upper end surface of each friction wheel 31 is provided with a shaft 311; the linkage mechanism 3 further comprises a transmission assembly, which comprises a transmission rod 331 extending in the transverse direction, the transmission rod 331 being arranged above the two friction wheels 31 and being in rotary connection with each shaft 311, so that the two friction wheels 31 can rotate synchronously. The shaft 311 is eccentrically arranged relative to the rotation center of the friction wheel 31. When the friction wheel 31 rotates around its rotation shaft, the shaft 311 moves with it. Since the transmission rod 331 is in rotary cooperation with it, when one friction wheel 31 is driven to rotate, the other friction wheel 31 can be driven to move synchronously, thereby ensuring the linkage effect. It can be understood that the rotary connection can be realized by corresponding shaft sleeves embedded on the transmission rod 331 and cooperating with the shaft 311, or by a simple shaft hole cooperation, which is not limited in the application.

[0062] In other embodiments, bearings can be arranged between each friction wheel 31 and its rotation shaft, and the two bearings are connected together through a gear transmission mechanism, so as to realize the linkage cooperation of the two friction wheels 31.

[0063] During the pushing and pulling process, the transmission rod 331 is always in a swinging state, so the synchronism of the two friction wheels 31 will also be affected by the horizontal state of the transmission rod 331. In an embodiment, please refer to Figure 5The first moving base 21 comprises a body and a mounting base 211 arranged above the body, and the friction wheel 31 is rotatably arranged on the upper end surface of the mounting base 211 along the up-down axis; the transmission assembly further comprises at least one auxiliary part 332, the auxiliary part 332 comprises a first rod segment and two second rod segments arranged at the two ends of the first rod segment, the two second rod segments extend away from each other in the up-down direction, and the two second rod segments are respectively connected to the mounting base 211 and the transmission rod 331 and can rotate relative to the mounting base 211 and the transmission rod 331. The auxiliary part 332 is in a Z shape as a whole, and can connect the transmission rod 331 and the mounting base 211 on which the friction wheel 31 is arranged. The mounting base 211 is fixed relative to the first moving base 21 during the pushing and pulling operation, so that the transmission rod 331 can be kept horizontal based on the mounting base 211 through the structure, and the synchronization of the two friction wheels 31 is ensured.

[0064] When the first moving base 21 is an independent profile, and the friction wheel 31 is directly arranged on the upper surface of the first moving base 21, one of the second rod segments of the auxiliary part 332 should be directly connected to the first moving base 21, so that the horizontal correction of the transmission rod 331 is realized through the first moving base 21 when the friction wheel 31 does not have the up-down adjustment function.

[0065] It can be understood that the rotary connection can be realized by corresponding embedding of a shaft sleeve on the transmission rod 331 and cooperation with the second rod segment, or can be realized by a simple shaft hole cooperation, and the present application does not limit this.

[0066] In the embodiment, two auxiliary parts 332 are arranged at intervals, so as to adapt to the length of the transmission rod 331 and the interval of the two friction wheels 31.

[0067] With the increase of the use time of the friction wheel 31, a gap may occur between the friction wheel 31 and the second moving base 22 due to wear, which will cause linkage failure. In view of this, in the embodiment, each friction wheel 31 has an active stroke in the up-down direction close to or away from the first moving base 21, so that the friction wheel 31 has a first position abutting against the two second moving bases 22 and a second position separated from the two second moving bases 22. Since the friction wheel 31 can be at the second position, each moving base can move independently and is not connected to each other, so as to facilitate disassembly. In actual use, the friction wheel 31 should always be kept at the first position, and when the friction wheel 31 has poor friction matching effect, the position of the friction wheel 31 can be adjusted, so as to adjust the friction degree and the abutting position, so that the mechanism has an adjustment function and ensures stable linkage effect.

[0068] It can be understood that when the second moving seat 22 and the friction wheel 31 are matched through the matching inclined surface 221 and the annular friction surface 312, the adjustment of the orientation of the friction wheel 31 in the up-down direction can achieve closer matching of the annular friction wheel 31 and the matching inclined surface 221, and increase the friction.

[0069] The present application does not limit the way of realizing the orientation-adjustable friction wheel 31. In one embodiment, a lifting adjustment structure such as a cylinder, a lead screw or the like can be arranged. Considering the limited space, in another embodiment, the first moving seat 21 comprises a body and a mounting seat 211 arranged above the body. The lower end surface of the mounting seat 211 is formed with a groove, so as to be capable of being covered outside the body, and the distance between the mounting seat 211 and the body is adjustable. The friction wheel 31 is rotatably arranged on the upper end surface of the mounting seat 211 along the axis extending in the up-down direction. At this time, the body is used for clamping the door leaf. The first moving seat 21 is split into the body as a mounting base and the mounting seat 211 capable of moving up and down. The mounting seat 211 is capable of driving the friction wheel 31 to move by the way of covering and matching, so as to ensure good guidance.

[0070] The present application does not limit the way of realizing the orientation-adjustable friction wheel 31. In one embodiment, a lifting adjustment structure such as a cylinder, a lead screw or the like can be arranged. Considering the limited space, in another embodiment, the first moving seat 21 comprises a body and a mounting seat 211 arranged above the body. The lower end surface of the mounting seat 211 is formed with a groove, so as to be capable of being covered outside the body, and the distance between the mounting seat 211 and the body is adjustable. The friction wheel 31 is rotatably arranged on the upper end surface of the mounting seat 211 along the axis extending in the up-down direction. At this time, the body is used for clamping the door leaf. The first moving seat 21 is split into the body as a mounting base and the mounting seat 211 capable of moving up and down. The mounting seat 211 is capable of driving the friction wheel 31 to move by the way of covering and matching, so as to ensure good guidance. Figure 3

[0071] In other embodiments, buckles can be arranged on the inner side wall of the mounting groove, and a plurality of clamping grooves of different heights are arranged on the outside of the body. The height adjustment of the mounting seat 211 can be realized by selecting the clamping grooves of different positions to match.

[0072] Please refer to Figure 7 ​The guide rail part 1 is formed with a first guide groove 1a extending in the transverse direction, and two second guide grooves 1b arranged opposite to each other in the longitudinal direction and below the first guide groove 1a; the first moving seat 21 is slidingly installed into the first guide groove 1a through a first guide wheel 23, and each two second moving seats 22 are slidingly installed into each second guide groove 1b through a second guide wheel 24. Such arrangement can ensure good sliding fit effect, the guide rail part 1 is arranged in two layers, the first guide wheel 23 and the second guide wheel 24 correspondingly arranged in the up-down direction, so that the structure is more compact, and the installation of the friction wheel 31 is facilitated, which is conducive to the design of miniaturization.

[0073] Further, the guide rail part 1 has a guide groove with an opening downward, in an embodiment, the middle part of the two side walls opposite to each other in the longitudinal direction is protruded with a first hook 11, and the two first hooks 11 together form the first guide groove 1a, that is, the first guide groove 1a is divided into two parts, and there is a gap between the two hooks for the structure connecting parts to pass through; the first guide groove 1a can also be arranged as an integral groove structure, and one side wall of the groove is arranged to be open to avoid the structure connecting parts. In another embodiment, the lower part of the two side walls opposite to each other in the longitudinal direction is protruded with a second hook 12, and the two second hooks 12 form two second guide grooves 1b, that is, the two second guide wheels 24 are arranged side by side.

[0074] In the embodiment, the middle part of the two side walls opposite to each other in the longitudinal direction is protruded with a first hook 11, and the two first hooks 11 together form the first guide groove 1a, and the lower part of the two side walls opposite to each other in the longitudinal direction is protruded with a second hook 12, and the two second hooks 12 form two second guide grooves 1b.

[0075] Further, please refer to Figure 8 The sliding assembly further includes two wheel seat structures 25 arranged opposite to each other, each wheel seat structure 25 includes a first seat body 251 and a second seat body 252, the first seat body 251 extends in the transverse direction and is fixedly installed on the first moving seat 21; the second seat body 252 extends in the up-down direction and is attached to the end of the first moving seat 21 in the transverse direction, and the upper end of the second seat body 252 is installed with the first guide wheel 23 on both sides in the longitudinal direction. That is, the first moving seat 21 is provided with two wheel seat structures 25 arranged opposite to each other to realize sliding fit, each wheel seat structure 25 is provided with two first guide wheels 23 to improve the stability of sliding fit, and the wheel seat structure 25 is used for hanging sliding, when the first moving seat 21 is a profile structure, the second seat body 252 can also play the role of a plug.

[0076] It can be understood that when the first moving seat 21 is a profile, the first seat body 251 is arranged in the cavity of the profile, and when the first moving seat 21 is composed of a body and a movable mounting seat 211, the first seat body 251 should be fixed on the body.

[0077] Furthermore, please follow the Figure 4 The lower end of the first moving seat 21 is provided with a hanger 4 for clamping the door leaf 200, and the hanger 4 is fixed to the first seat body 251 and the first moving seat 21 by bolts. That is, the screw of the hanger 4 can be connected in sequence through the first moving seat 21 and the first seat body 251, so as to connect the parts together. Generally, in order to adapt to the size of the door leaf, a plurality of hangers 4 are usually arranged to cooperate, and two hangers 4 can be connected to the first seat body 251.

[0078] In addition, the upper end of the second seat body 252 is provided with a avoiding groove, which provides sufficient space for the setting and swinging of the transmission rod 331.

[0079] In order to improve the stability, each second moving seat 22 is slidingly installed through two second guide wheels 24 which are transversely spaced. Each second guide wheel 24 is arranged on the side of the second moving seat 22 away from the friction wheel 31.

[0080] In the technical scheme of the embodiment, the upper part of each second moving seat 22 is inclined to form a matching inclined surface 221, and the matching inclined surface 221 is between the first hook 11 and the second hook 12. The lower part of each second moving seat 22 extends vertically to facilitate cooperation with the slot of the guide groove. The two second guide wheels 24 are both installed to the lower part of the second moving seat 22 and are transversely spaced.

[0081] It can be understood that the lower end of the first moving seat 21 and / or each second moving seat 22 is installed with the door leaf 200 through the hanger 4. The hanger 4 can clamp the glass door leaf 200 in a adjustable and detachable manner, which is stable and convenient to install. A reasonable number of hangers 4 can be set according to the size of the door leaf 200.

[0082] In the technical scheme of the embodiment, the adjusting bolt 321 passing through the body is counterclockwise screwed, at this time the spring 322 is elongated, the mounting seat 211 moves upward under the action of the pushing force, and the friction wheel 31 at the upper end of the mounting seat 211 will move away from the two second moving seats 22 until the friction linkage is in the disconnected state. At this time, the three door leaves 200 being clamped are moved respectively, so that the above-mentioned three door leaves 200 are overlapped, and the operator can perform corresponding assembly. The adjusting bolt 321 passing through the body is clockwise screwed, and the mounting seat 211 moves downward under the action of the adjusting bolt 321. The friction wheel 31 at the upper end of the mounting seat 211 will move close to the two second moving seats 22 until the extrusion and fit state of the annular friction surface 312 and the matching inclined surface 221 meets the requirements. At this time, the rubber ring 34 is extruded, the friction wheel 31 is in the compressed state, and the friction linkage is effective. When the left door leaf is moved, the corresponding second moving seat 22 moves to drive the friction wheel 31 to rotate. Due to the action of the door pushing direction, the right door leaf 200 remains stationary under its own inertia, and the middle door leaf 200 can follow the movement with a stroke ratio of 2 to 1. Finally, the three door leaves 200 are overlapped on the rightmost side. Please refer toFigure 10 If the right door leaf 200 is moved, the last three door leaves 200 overlap the leftmost one, as shown in FIG. 6. Figure 11 Both the forward and reverse movement of the two second moving seats 22 corresponding to the clamped door leaves 200 can be realized, and the movement of the three door leaves 200 together can also be realized, so that the user can enter and exit in any direction, and the three door leaves 200 can be overlapped at any push-pull position to maximize the entering and exiting space. The up and down adjustment function of the friction wheel 31 can keep the linkage effect stable.

[0083] The present application also provides a triple moving door, which comprises the triple moving mechanism 100 described above, and has all the technical features and effects of the triple moving mechanism 100, which will not be repeated here.

[0084] Further, based on the triple moving mechanism 100, the three door leaves 200 can be partially overlapped or separated from each other when the door is closed, as shown in FIG. 6. Figure 9 When the door is opened, one side can be selected to open, as shown in FIG. 7. Figures 10 to 11 Two sides can also be opened, and the three door leaves are all placed in the middle position, as shown in FIG. 8. Figure 12

[0085] The triple moving door can be applied in various scenes such as houses and office buildings.
