Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to a linkage device for a linkage door. Background Technology

[0002] Interlocking doors use drive belts and linkage devices to achieve the linkage of multiple door panels, thereby enabling the doors to open or close in unison by pushing or pulling. Currently, existing linkage devices have the following areas that require further improvement:

[0003] 1. When the door is open, multiple door panels are in an overlapping state. Some linkage devices do not have a limit function and need to be matched and installed separately. The limit block prevents the guide wheel of the linkage device from slipping off the guide rail and also prevents the door panels from being unevenly overlapped when the door is open due to reverse pushing. The existing linkage device has many components and is complicated to install.

[0004] 2. The opening direction of the linkage door is divided into left opening and right opening. Currently, the linkage device installed for the left opening and right opening states of the linkage door is different. The linkage device used for the left opening and the linkage device used for the right opening cannot be directly removed and interchanged. Since the linkage door is already installed with the drive belt and linkage device when it leaves the factory, the linkage door is fixed to the structure of left opening or right opening. If the opening direction needs to be changed or is incorrect during on-site installation, it cannot be solved on the spot. It is necessary to re-match and install the drive belt and linkage device, which not only affects the installation time and increases the time and labor costs, but also increases the company's inventory costs.

[0005] 3. The drive belt and linkage device are installed on the lower door frame, which also has guide pulleys. Since most linkage doors are suspended structures, the door leaf is suspended from the upper door frame by hangers. The guide pulleys provide support for the door leaf and share some of the load from the hangers. They also guide the door leaf during opening and closing, preventing it from shifting or swaying. After installation, if the guide pulleys are not in contact with the ground, the door leaf is prone to shifting or swaying. If the guide pulleys provide too much support to the door leaf, the hangers at the top of the door leaf may not engage with the slide rails on the upper door frame, resulting in uneven opening and closing. In this case, the guide pulleys need to be adjusted using tools to achieve the optimal position. However, the linkage device blocks the guide pulleys, requiring the door leaf to be removed for readjustment, which is very inconvenient.

[0006] To solve the above problems, a linkage device for the linkage door was specially developed. Utility Model Content

[0007] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a linkage device for a linkage door. The overall structure is simple, the installation is convenient, and it can be used for the installation of linkage doors with left and right opening without affecting the adjustment of the guide pulley.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a linkage device for a linkage door, comprising a base, a pulley and a linkage arm disposed on the base, characterized in that: the base is provided with an adjustment hole, a mounting plate extends from one end of the base, a pulley is provided on the upper part of the mounting plate, a screw seat is provided on the lower part of the mounting plate, the linkage arm is mounted through the screw seat, and a belt clamping part and a guide wheel are provided at one end of the linkage arm.

[0009] This utility model also includes a limiting block, and a limiting arm extends from one side of the limiting block. The limiting block is installed by a screw seat.

[0010] In this utility model, the linkage arm, the limiting block and the screw seat are provided with screw holes, and the linkage arm and the limiting block are detachably installed on the screw seat by screws through the screw holes.

[0011] In this utility model, the base is provided with card slots and lock holes on both sides.

[0012] In this utility model, the end of the linkage arm is provided with a clamping post, the belt clamping part includes a clamping arm, the clamping arm is provided with a clamping opening in the middle, the clamping post and the clamping arm are provided with corresponding adjustment holes, and the belt clamping part is installed and adjusted by screws through the clamping arm clamping the clamping post and the adjustment holes of the clamping post and the clamping arm.

[0013] In this invention, the guide wheel is mounted on the top of the belt clamping part.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The base has adjustment holes, allowing for readjustment of the guide pulley even after the interlocking door is installed on-site using an adjustment tool passing through the adjustment holes; one end of the base extends to a mounting plate with a pulley at the top and a screw seat at the bottom, through which the interlocking arm is mounted. One end of the interlocking arm has a belt clamp and a guide wheel. The base facilitates the installation of all functional components, resulting in a simpler overall structure; the interlocking arm, limit block, and screw seat have screw holes, allowing for detachable mounting of the interlocking arm and limit block to the screw seat via screws. Due to the detachable structure of the interlocking arm and limit block on the screw seat, the installation direction of the interlocking arm and limit block can achieve both left-opening and right-opening functions corresponding to the interlocking door, providing strong versatility and effectively reducing the company's inventory costs.

Detailed Implementation

[0024] 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.

[0025] As attached Figure 1-7As shown in the accompanying drawings, it should be noted that the application embodiments of this utility model in a linkage door will be described in detail, but the structure of the linkage door does not constitute a limitation on the claims of this utility model. A linkage device for a linkage door includes a base, a pulley and a linkage arm disposed on the base. The pulley is used for the installation and rotation of the transmission belt. The characteristic feature is that the base is provided with an adjustment hole. Because in traditional linkage devices, after installation, the door leaf needs to be removed to readjust the guide pulley after blocking it, this utility model allows for adjustment by passing an adjustment tool through the adjustment hole. The guide pulley can be adjusted more easily. A mounting plate extends from one end of the base. A pulley is located on the upper part of the mounting plate, and a screw seat is located on the lower part of the mounting plate. The linkage arm is installed through the screw seat, which is generally installed with screws. This forms a detachable structure for the linkage arm on the screw seat, which can be installed with the linkage arm facing left or right. One end of the linkage arm is provided with a belt clamping part and a guide wheel. The belt clamping part and the guide wheel are installed at the corner end of the linkage arm. The belt clamping part forms a clamping installation structure for the transmission belt, which can realize secondary cutting and clamping installation of the transmission belt on site.

[0026] This utility model also includes a limiting block, with a limiting arm extending from one side of the limiting block. The limiting block is installed by a screw seat. The limiting arm can prevent the guide wheel of the linkage device from slipping off the guide rail, and also prevent the door from overlapping and becoming uneven when the door is pushed back.

[0027] In this utility model, the linkage arm, the limiting block, and the screw seat are provided with screw holes. The linkage arm and the limiting block are detachably installed on the screw seat through the screw holes using screws. The linkage arm and the limiting block can be easily installed and removed on the screw seat. Thus, by adjusting the left or right orientation of the linkage arm and the limiting block, the left-opening and right-opening structures of the linkage door can be matched.

[0028] In this utility model, the base is provided with a card seat and a lock hole on both sides. The card seat is a protrusion that protrudes to both sides. During the installation process, the bottom rail of the lower door frame can be provided with a corresponding concave installation groove. After the card seat is inserted into the installation groove, the lock hole is installed with a set screw to tighten the base, thereby realizing the installation structure of the base. The structure is simple and easy to disassemble and assemble.

[0029] In this utility model, the end of the linkage arm is provided with a clamping post, and the belt clamping part includes a clamping arm with a clamping opening in the middle. The clamping post and the clamping arm are respectively provided with adjustment holes. The belt clamping part clamps the clamping post through the clamping arm and is installed and adjusted by screws through the adjustment holes of the clamping post and the clamping arm. When the belt is cut to a suitable length, it is inserted into the clamping opening through two broken parts and then locked by screws to form the connection and installation of the transmission belt. Furthermore, the secondary cutting and connection installation of the belt can be realized on the site of the linkage door installation.

[0030] In this invention, the guide wheel is installed on the top of the belt clamping part. Commonly, the guide wheel can be installed with bolts. The guide wheel forms a linkage guiding function in the opening and closing process of the door leaf, so that the adjacent door leaves maintain a fixed distance and form a more stable opening and closing action of the door leaf.

[0031] Working principle:

[0032] When applying it, a drive belt also needs to be installed. A bottom rail is provided at the bottom of the door frame. The bottom rail is provided with a mounting groove and a guide rail. This part of the structure is used to further illustrate the present utility model and is not intended to limit the conditions under which the present utility model can be implemented.

[0033] refer to Figure 1-7 The base is installed at the bottom of the lower door frame via the mounting groove of the bottom rail. The transmission belt is installed on the pulley of the base. The linkage arm and the limit block are detachably installed on the screw seat via screw holes. The belt clamping part on the linkage arm clamps the transmission belt. The guide wheel on the linkage arm is located in the guide rail of the bottom rail to provide linkage guidance during the opening and closing of the door, so that the adjacent door leaves maintain a fixed distance and the door leaves open and close more smoothly. The limit block provides a limiting function for the door leaves when they open to the overlapping position, so that the overlapping position of the door leaves is more neat and more beautiful after the door leaves are opened.

[0034] When installing on-site, if the door opening direction needs to be changed or is incorrect, the correct door opening direction can be achieved by removing the linkage arm and limit block and reinstalling them in reverse. There is no need to re-match and install the drive belt and linkage device, which effectively saves installation time and labor costs. When producing, the company does not need to open multiple sets of molds, and the inventory cost is also lower.

[0035] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
