Description

Technical Field

[0001] The utility model relates to the technical field of door and window hardware, in particular to a transmission belt clamp structure of a linkage door. Background Art

[0002] Nowadays, linkage door systems are widely used to achieve automatic opening and closing of doors, especially in situations where efficient flow control is required or space is limited. Among them, sliding doors are popular due to their simple structure and convenient operation. However, traditional sliding door linkage systems, especially when it comes to using belt drives to achieve door linkage, face some technical challenges.

[0003] Traditional linkage door drive belt clamp assemblies usually consist of two parts: a drive belt clamp and a linkage. The drive belt clamp is designed to connect with the drive belt set on the middle sliding door, while the linkage is used to fix on the outer sliding door. The two components are fixedly connected in some way to ensure that the sliding door can be opened and closed synchronously when the drive belt moves.

[0004] However, the conventional linkage door drive belt clamp assembly has obvious limitations. Since the drive belt clamp is designed to move only along the straight section of the drive belt, this limits the range of motion of the sliding door during folding and unfolding. Specifically, when the drive belt and the drive pulley fit together to form an arc segment, the conventional drive belt clamp cannot effectively move along this arc segment.

[0005] This limitation leads to two major problems. First, in order to achieve a flush end surface when the sliding door is folded, a compromise may need to be made in the design, sacrificing the degree of expansion of the sliding door. This means that when the door body needs to be fully opened to accommodate large objects or provide more space for passage, the sliding door may not be fully expanded. Second, if the design prioritizes the full expansion of the sliding door, the end surface may not remain flush when the door body is folded, affecting the aesthetics. Utility Model Content

[0006] In order to overcome at least one of the defects of the prior art, the utility model provides a transmission belt clamp structure for a linkage door, which can solve the problem of fully unfolding the sliding door and the flush end surface of the door body when folding.

[0007] The technical solution adopted by the utility model to solve the problem is:

[0008] A transmission belt clamp structure for a linkage door, used for being assembled between two adjacent linkage door bodies, characterized in that it comprises: a transmission belt clamp, wherein the transmission belt clamp is used to follow the transmission belt of one of the linkage door bodies to make linear motion, and the transmission belt clamp comprises a clamp assembly portion; a linkage member, wherein the linkage member comprises a linkage member mounting portion located at one end of the linkage member and a transmission belt clamp assembly platform located at the other end of the linkage member, and the linkage member mounting portion is assembled to the other linkage door body, and the direction of movement of the linkage door body is set to a first direction, then a sliding hole is provided on the transmission belt clamp assembly platform along the first direction, the clamp assembly portion is slidably arranged in the sliding hole, and one end of the clamp assembly portion passes through the sliding hole and is connected to a limiting bottom plate.

[0009] By adopting the above scheme, when the linked door bodies are folded or opened, the sliding hole can enable the clamp assembly part to continue to slide in the direction of movement of the linked door bodies, so that the two door bodies can achieve a flush effect when folded, and the two linked door bodies can be fully opened when opened, so as to maximize the space utilization.

[0010] Furthermore, a concave sliding groove is provided on one side of the transmission belt clamp assembly platform facing the transmission belt clamp, a limiting baffle is formed around the edge of the sliding groove, and the sliding hole is located in the sliding groove.

[0011] By adopting the above solution, the limiting baffle can limit the sliding of the transmission belt clamp to prevent the transmission belt clamp from sliding out of the sliding hole or the sliding groove.

[0012] Furthermore, a concave sliding rail is provided on a side of the transmission belt clamp facing the transmission belt clamp assembly platform, and the sliding rail slides along a portion of the limiting baffle plate that is parallel to the first direction.

[0013] By adopting the above solution, the concave sliding rail cooperates with the limit baffle to form a guiding structure, thereby improving the sliding stability of the transmission belt clamp and avoiding deviation of the transmission belt clamp when sliding.

[0014] Furthermore, the transmission belt clamp is provided with a transmission belt clamping groove facing away from the clamp assembly portion, and the transmission belt clamping groove is open at both ends perpendicular to the first direction. A transmission belt column for winding the transmission belt is provided in the transmission belt clamping groove, and the transmission belt column is spaced apart from the side wall of the transmission belt clamping groove.

[0015] By adopting the above solution, the transmission belt can be conveniently fixed on the transmission belt column in the transmission belt clamping groove.

[0016] Furthermore, the side wall of the transmission belt clamping groove is provided with a plurality of convex ribs facing the transmission belt column.

[0017] By adopting the above solution, the convex ribs can increase the friction between the transmission belt and the transmission belt column, thereby improving the firmness of the transmission belt fixation.

[0018] Furthermore, two transmission belt columns are provided, and the two transmission belt columns are spaced apart and perpendicular to the first direction.

[0019] By adopting the above solution, the linkage member can be selected according to the position of the transmission belt after assembly.

[0020] Furthermore, the clamp assembly portion includes at least one extension column arranged toward the sliding hole, and a rolling sleeve is rotatably connected to the extension column, and the rolling sleeve rolls along the side wall of one side of the sliding hole.

[0021] By adopting the above solution, when the clamp assembly part slides along the sliding hole, the rolling sleeve rolls along the side wall of one side of the sliding hole due to the friction force, thereby improving the smoothness of the sliding of the clamp assembly part in the sliding hole.

[0022] Further, the linkage member includes a transition portion located between the linkage member mounting portion and the drive belt clamp assembly platform, the transition portion has an avoidance groove, and the distance from the drive belt clamp assembly platform to the avoidance groove is not greater than the distance from the linkage member mounting portion to the avoidance groove.

[0023] By adopting the above solution, the avoidance groove can avoid the groove wall between the door frames, and the transmission belt clamp assembly platform provides an installation space for the transmission belt clamp.

[0024] Furthermore, the distance from the side of the transmission belt clamp away from the transmission belt clamp assembly platform to the avoidance groove is not greater than the distance from the side of the linkage member mounting portion away from the avoidance groove to the avoidance groove.

[0025] By adopting the above solution, the force points between the two linked door bodies can be kept horizontal, thereby ensuring that the linked door bodies are subjected to stable force.

[0026] Furthermore, the linkage member mounting portion includes a strip-shaped assembly hole, the strip-shaped assembly hole is perpendicular to the first direction, and an opening direction of the strip-shaped assembly hole is consistent with the first direction.

[0027] By adopting the above solution, the strip-shaped assembly hole can adjust the relative position of the linkage door body and the strip-shaped assembly hole according to the distance between the two linkage door bodies, so as to adapt to the installation of linkage parts with different linkage door body intervals.

[0028] In summary, the transmission belt clamp structure of a linkage door provided by the utility model has the following technical effects:

[0029] 1. Expand the range of motion of the sliding door: By introducing the design of the sliding hole, the drive belt clamp can follow the linkage door body to slide along the arc segment during the folding and unfolding process, rather than just being limited to the straight segment. This greatly expands the range of motion of the sliding door, allowing the sliding door to be fully unfolded when needed to accommodate large objects or provide a larger passage space;

[0030] 2. Achieve flush end faces when the door body is folded: Since the sliding hole allows the clamp assembly to continue to slide when the linked door body is folded, it can ensure that the two door bodies are flush when folded. This not only improves the aesthetics of the door body, but also helps to maintain the sealing and stability of the door;

[0031] 3. Improve the flexibility and reliability of the system: The design of this transmission belt clamp structure increases the flexibility and reliability of the system. When the transmission belt and the transmission pulley fit together to form an arc segment, even if the transmission belt clamp reaches the arc segment, the door body can continue to move due to the existence of the sliding hole, thereby ensuring the normal operation of the linkage door system.

[0048] In summary, the transmission belt clamp structure of a linkage door provided by the utility model has the following technical effects:

[0049] 1. Expanding the range of motion of the sliding door: By introducing the design of the sliding hole 321, the driving belt clamp 2 can follow the linkage door body 1 to slide along the arc segment during the folding and unfolding process, rather than being limited to the straight line segment. This greatly expands the range of motion of the sliding door, allowing the sliding door to be fully unfolded when needed to accommodate large objects or provide a larger passage space;

[0050] 2. Achieve flush end faces when the door body is folded: Since the sliding hole 321 allows the clip assembly part 21 to continue to slide when the linked door body 1 is folded, it can ensure that the two door bodies are flush when folded. This not only improves the aesthetics of the door body, but also helps to maintain the sealing and stability of the door;

[0051] 3. Improve the flexibility and reliability of the system: The design of this transmission belt clamp structure increases the flexibility and reliability of the system. When the transmission belt and the transmission pulley fit together to form an arc segment, even if the transmission belt clamp 2 reaches the arc segment, the door body can continue to move due to the existence of the sliding hole 321, thereby ensuring the normal operation of the linkage door system.
