[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0028] like Figure 1 As shown, the prior art Chinese patent application CN201510780403.7 discloses a double-door linkage device, including a left door shaft, a left door center shaft, and a left sliding wheel for installation at the left door, and a right door shaft, a right door center shaft, and a right sliding wheel installed at the right door, and also includes a transmission line 1 and a transmission line 2, one end of the transmission line 1 fixes the right door shaft, and the other end passes through the right sliding wheel and is fixed to the left door center shaft; one end of the transmission line 2 fixes the left door shaft, and the other end passes through the left sliding wheel and is fixed to the right door center shaft.

[0029] In the above prior art, although the linkage opening and closing of the left and right doors can be realized, the arrangement of the entire linkage mechanism requires a large space on the top of the door. In addition, after the arrangement, the linkage mechanism is exposed to the outside, which only needs to ensure the basic functions for industrial decoration, but for home or commercial use, the above defects greatly reduce the practicality of the linkage door.

[0030] like Figure 2As shown, in order to solve the problem that the linkage mechanism of the existing linkage door occupies a large space and cannot be covered, the utility model provides a hidden linkage screen door, including a left and right screen door body I 101 and a screen door body II 102 arranged side by side; the screen door body I 101 and the screen door body II 102 can slide along a track; and also include a linkage device for the screen door body I 101 and the screen door body II 102 to slide toward or away from each other along the track at the same time; the linkage device includes a wiring mechanism I 102 and a wiring mechanism II 202 installed on the screen door body I 101 and the screen door body II 102; and also includes a fixed pulley I 103 and a fixed pulley II 203 respectively fixed at two ends of the track; one end of the linkage line I 104 is fixed to the wiring mechanism I 102 on the screen door body I 101, and the other end is connected to the wiring mechanism II 202 on the screen door body II 201 after bypassing the fixed pulley I 103; one end of the linkage line II 204 is fixed to the screen door body II The wiring mechanism I 102 and the wiring mechanism II 202 are respectively arranged at the adjacent corners of the screen door body I 101 and the screen door body II 201; the fixed pulley I 103 and the fixed pulley II 203 are located at the same height as the wiring mechanism I 102 and the wiring mechanism II 202, so that the linkage line I 104 and the linkage line II 204 are hidden in the track.

[0031] In the utility model, the fixed pulley is arranged in the track and is hidden by the track. The wiring mechanism is arranged at the corner of the screen door body. Since the end of the screen door body needs to slide with the track, the corner of the screen door body is also shielded by the track while cooperating with the track, so the wiring mechanism arranged on the corner of the screen door body is also shielded. In addition, the linkage line is arranged between the wiring mechanism and the fixed pulley, and is also hidden in the track. In this way, all parts used for linkage are shielded by the track and do not occupy extra space, which greatly improves the aesthetics of the screen door and is suitable for home or commercial use.

[0032] In order to facilitate the concealment of the linkage device, in this embodiment, an axial slide groove is provided on the track, and the ends of the screen door body I 101 and the screen door body II 201 are clamped in the slide groove and can slide along the slide groove; the fixed pulley I 103 and the fixed pulley II 203 are arranged in the slide groove. The slide groove on the track cooperates with the screen door body to slide, and the linkage device is also hidden by the slide groove.

[0033] In order to make the screen door body run more stably, the track includes a ceiling track 300 and a floor track 400 respectively arranged at the top and bottom of the door opening; the top and bottom of the screen door body I 101 and the screen door body II 201 respectively cooperate with the ceiling track 300 and the floor track 400 for sliding; the linkage device is two sets, which are respectively arranged at the top and bottom of the screen door body I 101 and the screen door body II 201. After such arrangement, the upper and lower ends of the screen door body both have force points for sliding, and both are also equipped with linkage devices to make the upper and lower ends evenly stressed, so as to avoid the screen door body from tilting and derailing due to uneven force on the upper and lower ends when sliding.

[0034] Since the screen door itself is relatively tall and heavy, it still lacks stability if it is only linked by the linkage devices arranged at the upper and lower ends of the screen door body. Therefore, in the utility model, a plurality of auxiliary linkage lines 600 are also included; one end of the auxiliary linkage line 600 is connected to the screen door body I 101, and the other end is connected to the screen door body II 201 after being laid along the track.

[0035] The function of the auxiliary linkage line 600 is not to link the screen door body I 101 and the screen door body II 201, but to make the screen door body I 101 and the screen door body II 201 smoother during the sliding process. The auxiliary linkage line 600 is equivalent to a flexible track, so that the screen door body can move along it.

[0036] Of course, since the auxiliary linkage line 600 is set in the middle of the screen door body, in order to avoid it blocking the door opening and to further improve the stability, the auxiliary linkage line 600 is used as an example to describe its winding direction: one end of the auxiliary linkage line 600 is fixed to a fixed point 601 on the side of the screen door body I 101 away from the screen door body II 201, and the other end transversely penetrates the screen door body I 101, bypasses the winding point 602 set on the side of the screen door body I 101 close to the screen door body II 201 and extends toward the track (ground track 400), bypassing the winding point 602 set on the screen door body I 101. The winding point 603 at the corner of screen door body 101 extends along the track (ground track 400) to the screen door body II201, bypasses the winding point 604 set at the corner of the screen door body II201 and extends to the middle of the screen door body II201, bypasses the winding point 605 set on the side of the screen door body II201 close to the screen door body I101, and then transversely penetrates the screen door body II201 and is fixed to the fixing point 606 set on the side of the screen door body II201 away from the screen door body I101.

[0037] It is foreseeable that a portion of the auxiliary linkage line 600 may extend along the upper ceiling rail 300 , while another portion of the auxiliary linkage line 600 may extend along the lower ground rail 400 .

[0038] In addition, the fixing points of the same auxiliary linkage line 600 on the screen door body I 101 and the screen door body II 201 are at different heights to prevent the linkage line from being locked and unable to slide. At the same time, the diagonal connection can further improve stability.

[0039] In this embodiment, there are multiple auxiliary linkage lines 600, which are arranged equidistantly along the height direction of the screen door body I 101 and the screen door body II 201. The number of auxiliary linkage lines 600 can be set according to the height of the screen door body. The higher the door, the more auxiliary linkage lines are needed to ensure the smooth operation of the screen door body.

[0040] For the convenience of pushing and pulling, a handle 500 for pushing and pulling is provided on one side adjacent to the screen door body I 101 and the screen door body II 201. When the screen door body on one side is pushed or pulled, the screen door body on the other side also does a mirror linkage, so that the two screen door bodies can be opened and closed in linkage.

[0041] In this embodiment, the length of the linkage line can be adjusted by using a wiring mechanism. Specifically, the wiring mechanism is provided with an adjusting bolt for adjusting the length of the linkage line. When the length of the linkage line needs to be adjusted, it is only necessary to adjust the linkage line to a suitable length and then tighten it by adjusting the bolt.

[0042] The utility model realizes the opening and closing linkage of the left and right screen door bodies through the linkage device, and hides the linkage device through the track, so that it is more beautiful and does not occupy extra space.

[0043] In this embodiment, by arranging rollers and tracks at the bottom of the screen door body I101 and the screen door body II201, the sliding is smoother and the feel when pushing and pulling is improved.

[0044] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
