Description

Technical Field

[0001] This utility model relates to the field of reverse linkage door technology, specifically a linkage door linkage system. Background Technology

[0002] Chinese Patent Publication No. CN212927467U discloses an installation mechanism and a synchronous reverse linkage door. The technical solution includes: an upper guide rail; an upper hanging pulley slidably mounted on the upper guide rail; a hanging box for installation on the upper frame of the door leaf, the hanging box being connected to the upper hanging pulley, and a fixing adjustment device on the hanging box; and a transmission wheel assembly mounted on the upper guide rail, with a transmission component connected to the fixing adjustment device wound around the transmission wheel assembly to drive the two door leaves to move synchronously in opposite directions. This installation mechanism has a clever and simple structure, making the hanging box and fixing adjustment device an integral component. This allows the hanging box, fixing adjustment device, upper hanging pulley, transmission wheel assembly, and transmission component to be installed and connected to the upper guide rail as a whole before the upper guide rail is installed. Then, the upper guide rail is installed on the door frame, and finally, the door leaves are hung and simply fixed and adjusted before use, achieving easy installation.

[0003] Chinese Patent Publication No. CN218061962U discloses a device for preventing belt slippage in a linkage door and a linkage door installation system. The technical solution includes: a wheel base with a pulley for winding a transmission component; and an anti-slip baffle connected to the wheel base, wherein the anti-slip baffle is close to the pulley. This technical solution solves the problem of the stretched belt not slipping off the pulley within a limited stretching range, effectively extending the service life of synchronous reverse linkage doors.

[0004] However, the above-mentioned existing technical solutions have the following drawbacks:

[0005] 1. The drive wheels and drive components are installed into the mounting slots during on-site construction. Due to the limited on-site construction environment and possible installation errors between different installers, the linkage effect of the linkage door is poor.

[0006] 2. There are generally two transmission wheels. The transmission wheels are connected by a tension transmission component. The contact area between the transmission component and the transmission wheel is large, the friction is large, and the transmission efficiency is low.

[0007] 3. During long-term use, the transmission components are prone to material fatigue, which can cause the contact between the transmission components and the transmission wheel to weaken, resulting in the transmission components falling off the transmission wheel.

[0008] Therefore, we propose a linkage door linkage system to solve the problems mentioned above. Utility Model Content

[0009] The purpose of this invention is to provide a linkage system for interlocking doors to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, this utility model provides the following technical solution: a linkage door linkage system, comprising: an outer track and an inner track, wherein the outer track and the inner track are installed on a wall or a wooden cabinet, there are two outer tracks, and the inner track is located between the two outer tracks, and the outer track and the inner track have the same structure;

[0011] Both ends of the external track are equipped with pulley assemblies, and both ends of the internal track are equipped with linkage assemblies. Both the external and internal tracks have one main groove and two secondary grooves. The secondary grooves are located on both sides of the main groove, and linkage assemblies or pulley assemblies are installed at both ends of the main groove.

[0012] The telescopic connecting rod is fixedly installed in the main groove of the inner track by bolts, and the linkage components are fixedly installed at both ends of the telescopic connecting rod.

[0013] The linkage component includes a traction guide seat, and two symmetrical fixed pulleys are rotatably arranged inside the traction guide seat, through which the traction rope passes.

[0014] Both the linkage assembly and the pulley assembly include a linkage arm, which is fixedly installed in the secondary groove of the track where the secondary track is located. The linkage arm is equipped with a guide pulley, which is slidably connected to the adjacent secondary groove of the track.

[0015] The linkage arm at the front end of the external track on the left is fixedly connected to the traction rope inside the internal track, and the linkage arm at the rear end of the external track on the right is fixedly connected to the traction rope inside the internal track.

[0016] The connection between the traction rope and the linkage arm is in the shape of an "eight". The "eight" structure moves with the traction rope to the side of the fixed pulley and fits into the fixed pulley.

[0017] Preferably, the pulley assembly at the front end of the external track on the left and the pulley assembly at the rear end of the external track on the right are both connected to the traction rope of the internal track.

[0018] Preferably, the telescopic linkage consists of a first telescopic rod and a second telescopic rod that slide in a fitted manner, with a linkage component fixedly installed at the far end of the first telescopic rod and the second telescopic rod.

[0019] Preferably, the linkage component further includes a main body fixing seat, which is fixedly connected to the telescopic connecting rod by a high-strength metal connector. A traction guide seat is fixedly installed on the main body fixing seat, and wire grooves are provided on both sides of the traction guide seat. The traction rope passes through the fixed pulley along the wire grooves.

[0020] Preferably, the bottom of the main body fixing seat is provided with a protruding edge, which is slidably engaged in the inner track.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. The main body fixing base can be pre-set according to the movable width of the mounting slot before leaving the factory. In the actual installation process, it is only necessary to fix the fixed pulley together with the telescopic connecting rod of the set length to the main body fixing base. This can not only ensure the accuracy between the fixed pulleys, but also simplify the installation process.

[0023] 2. The fixed pulleys have been changed from the original two large transmission wheels to four small fixed pulleys. Two fixed pulleys are grouped together. By combining two fixed pulleys, the support area between the traction rope and the transmission wheel is reduced, making it more labor-saving. The number of fixed pulleys has been changed from one to two, which can withstand greater pressure, thereby improving the service life of the transmission components.

[0024] 3. The traction guide seat is equipped with a closed through groove for installing the fixed pulley and through which the traction rope passes, ensuring that the traction rope on the fixed pulley will not fall off. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figure 1-12 This utility model provides a technical solution: a linkage door linkage system, including: an outer track 1 and an inner track 2, the outer track 1 and the inner track 2 are installed on a wall or wooden cabinet for installing a door panel, so that the door panel can slide along the outer track 1 and the inner track 2. There are two outer tracks 1, and the inner track 2 is located between the two outer tracks 1. The outer track 1 and the inner track 2 have the same structure. Pulley assemblies 5 are installed at both ends of the outer track 1, and linkage assemblies 6 are installed at both ends of the inner track 2. The linkage assemblies 6 are connected by a traction rope 10.

[0040] The pulley assembly 5 at the front end of the left outer track 1 and the pulley assembly 5 at the rear end of the right outer track 1 are both connected to the traction rope 10 of the inner track 2. When one of the outer tracks 1 moves, it pulls the traction rope 10, causing it to drive the other outer track 1 to move in the opposite direction, thus achieving linkage.

[0041] Specifically, both the outer track 1 and the inner track 2 are provided with one main groove 9 and two secondary grooves 8. The secondary grooves 8 are located on both sides of the main groove 9. The two ends of the main groove 9 are equipped with linkage components 6 or pulley components 5. The secondary grooves 8 are used to guide the moving door panel.

[0042] Telescopic connecting rod 7 is fixedly installed in the main groove 9 of the inner track 2 by bolts. The telescopic connecting rod 7 is composed of a first telescopic rod 71 and a second telescopic rod 72 that slide together. The linkage component 6 is fixedly installed at the far end of the first telescopic rod 71 and the second telescopic rod 72. By fixing the cross length of the first telescopic rod 71 and the second telescopic rod 72, the overall length of the telescopic connecting rod 7 is fixed, thereby fixing the distance between the two linkage components 6, which is used to match the length of different inner tracks 2.

[0043] The linkage component 6 includes a main body fixing seat 61, which is fixedly connected to the telescopic connecting rod 7 via a high-strength metal connector 62. A traction guide seat 64 is fixedly installed on the main body fixing seat 61. Two symmetrical fixed pulleys 641 are rotatably arranged inside the traction guide seat 64. A wire groove 642 is opened on both sides of the traction guide seat 64. The traction rope 10 passes through the fixed pulleys 641 along the wire groove 642, so that the traction rope 10 can move between the two linkage components 6. The design of double fixed pulleys 641 can reduce the contact area between the fixed pulleys 641 and the traction rope 10.

[0044] The bottom of the main body fixing seat 61 is provided with a protruding edge, which slides and engages in the inner track 2 to prevent the linkage component 6 from disengaging from the inner track 2.

[0045] Both the linkage assembly 6 and the pulley assembly 5 include a linkage arm 63, which is fixedly installed in the secondary groove 8. The linkage arm 63 is provided with a guide pulley 631, which is slidably connected to the adjacent track secondary groove 8.

[0046] The linkage arm 63 at the front end of the left outer track 1 is fixedly connected to the traction rope 10 inside the inner track 2, and the linkage arm 63 at the rear end of the right outer track 1 is fixedly connected to the traction rope 10 inside the inner track 2.

[0047] The connection between the traction rope 10 and the linkage arm 63 is in a figure-eight structure. When the connection moves to the outside of the fixed pulley 641, because the fixed pulley 641 is small, the figure-eight opening at the connection of the traction rope 10 just fits on the fixed pulley 641, thereby correcting the position of the linkage arm 63. It will not become crooked due to the contact between the connection of the traction rope 10 and the fixed pulley 641, thus preventing the linkage door panels from being non-parallel.

[0048] Working principle: The first telescopic rod 71 and the second telescopic rod 72 are engaged with each other, and then the main body fixing seat 61 is installed on the ends of the first telescopic rod 71 and the second telescopic rod 72 respectively;

[0049] Insert the components from the previous step into the main slot 9 of the inline track 2, and extend the first telescopic rod 71 and the second telescopic rod 72 until the telescopic connecting rod 7 is the same length as the inline track 2. Fix the telescopic connecting rod 7 to the inline track 2 with screws.

[0050] The traction guide seat 64 with the fixed pulley 641 is fixed on the main body fixed seat 61, and then the traction rope 10 is looped on the fixed pulley 641 and tightened.

[0051] The traction rope 10 is fixedly connected to the two side linkage arms 63. By moving one of the door panels, the traction rope 10 is driven to rotate, thereby causing the other door panel to move in the opposite direction synchronously.

[0052] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
