Description

Technical Field

[0001] This utility model relates to the field of door panel equipment, and in particular to a connector and its corresponding anti-detachment door structure. Background Technology

[0002] In theory, automatic doors are an extension of the concept of doors, representing the development and improvement of door functions based on human needs. The automatic door industry has matured significantly. An automatic door is defined as a system that uses a control unit to recognize a person's approach to the door (or some form of entry authorization) as an opening signal, opens the door through a drive system, and automatically closes the door after the person leaves, thus controlling the opening and closing process.

[0003] Most existing automatic doors consist of two doors, both moving at the same speed. During operation, automatic doors are susceptible to swaying due to external factors such as wind. Currently, the market uses horizontal baffles on the sides of the door's track to limit the door's movement and prevent it from slipping out. However, the friction between the horizontal baffle and the door is relatively high, resulting in poor door stability. Furthermore, the door is prone to jamming when subjected to lateral forces, making it inconvenient to use and contributing to poor operational stability.

[0004] Therefore, it is necessary to provide an anti-slip door structure to solve the above problems. Utility Model Content

[0005] This utility model relates to a connector and its corresponding anti-slip door structure. The connector includes a connecting block, a connecting rod, and an adjusting roller. The adjusting roller cooperates with a first sliding member to clamp and slide on the track beam, effectively preventing the door leaf from swinging to both sides under lateral external forces. The first sliding member and the adjusting roller reduce the friction of the door leaf, making its operation more stable. Moreover, the door leaf will not jam under external forces during operation, resulting in higher stability and greater ease of use. This solves the problem of high friction and poor stability in the prior art where a horizontal baffle limits the door leaf.

[0006] To solve the above problems, the present invention provides a connector comprising:

[0007] Connecting block, used for fixed connection with the door leaf;

[0008] A connecting rod, one end of which is fixedly connected to the connecting block; and,

[0009] An adjusting roller is fitted to the other end of the connecting rod, and one side of the adjusting roller is attached to the track beam; the adjusting roller and the first sliding member are offset vertically to clamp the door leaf to the track beam.

[0010] Furthermore, an adjusting screw hole is provided at the other end of the connecting block. The connecting rod is configured as a bolt structure, with one end of the connecting rod threaded into the adjusting screw hole. The adjusting roller is connected to the connecting rod by a bearing, which helps to reduce the frictional resistance when the door slides and can also reduce the axial swing of the door on the adjusting roller, resulting in more stable operation.

[0011] Furthermore, the connector also includes at least one adjusting nut, which is threadedly connected to one end of the connecting rod. The adjusting nut is located between the adjusting roller and the connecting block, so that the adjusting roller is clamped and fixed between the adjusting nut and the nut of the connecting rod, which facilitates the adjustment of the position and size of the adjusting roller, enhances compatibility, and makes installation and debugging more convenient and quick.

[0012] Furthermore, a limiting groove is provided along the length of the side of the track beam that contacts the adjusting roller, and the side of the adjusting roller that protrudes from the connecting rod is disposed within the limiting groove. Thus, the limiting groove allows the adjusting roller to fit more tightly with the track beam, resulting in better anti-swaying of the door leaf.

[0013] An anti-slip door structure includes any of the connecting members described above, and further includes:

[0014] A track beam, wherein a first mounting plate protrudes from one side of the track beam body along its length direction; and,

[0015] A door panel assembly includes a first door panel, a first sliding member, and at least one connecting member; the upper end of the first door panel is fixedly connected to one side of the first sliding member, and at least two sets of the first sliding members are provided; the first sliding member is slidably connected to one side of a first mounting plate; at least one connecting member is connected to the side of the first door panel where the first sliding member is provided, and the connecting member is attached to the other side of the first mounting plate; the first sliding member and the connecting member are vertically offset, and the first sliding member and the connecting member cooperate to clamp the first door panel onto the first mounting plate.

[0016] Furthermore, the first sliding member includes a pulley and a connecting shaft. One end of the connecting shaft is fixed to the first door leaf, and the pulley is fitted onto the other end of the connecting shaft. The circumferential side of the pulley is slidably connected to the first mounting plate.

[0017] Furthermore, the door assembly also includes a second door leaf, a first transmission assembly, and a first adjusting seat. The first door leaf is fixedly connected to one side of the first adjusting seat, and the first adjusting seat is provided with the first sliding member. At least one of the connecting members is connected to the first adjusting seat. The first door leaf and the second door leaf are horizontally spaced apart, and the first adjusting seat and the second door leaf are connected through the first transmission assembly, so that the first door leaf drives the second door leaf to move through the first adjusting seat and the first transmission assembly. This design is compact, lower in cost, and highly efficient in opening and closing the door.

[0018] Furthermore, the first adjusting seat includes a first adjusting plate and a fixing plate disposed on one side of the first mounting plate. The first adjusting plate has a first sliding member on the side facing the first mounting plate, and the other side of the first sliding member has multiple adjusting positions along the height direction for adjusting the height of the connecting block, with the connecting block fixed to the adjusting positions. The first adjusting plate also has multiple sets of adjusting positions spaced apart along its length. One end of the fixing plate is fixedly connected to the first adjusting plate, and the other end of the fixing plate is fixedly connected to the first door leaf, thereby making the height of the central axis of the adjusting roller adjustable to accommodate adjusting rollers of different sizes, resulting in higher compatibility and a tighter fit.

[0019] Furthermore, a set of limiting devices is provided between the lower ends of the first door leaf and the second door leaf. The limiting device includes a first limiting member and a second limiting member. The first limiting member is disposed on the second door leaf, and the second limiting member is fixed to the first door leaf and located at the far end of the first limiting member's movement direction. The length direction of the first limiting member is along the sliding direction of the second door leaf, and the end of the second limiting member away from the second door leaf abuts against the first limiting member and is slidably connected along the length direction of the first limiting member. This limiting device ensures that the gap between two adjacent door leaves is always maintained within a certain range, preventing the two door leaves from swinging and affecting each other, thus improving safety performance.

[0020] Furthermore, the first limiting member is configured as a strip structure, with a groove along its length, and one side of the groove is open. The second limiting member is slidably disposed within the groove on the side opposite to the first door leaf. The structure is simple and easy to install and disassemble.

[0021] This utility model, by employing the aforementioned connector and its corresponding anti-detachment door structure, offers the following advantages compared to existing technologies: The connector includes a connecting block, a connecting rod, and an adjusting roller. The connecting block is used for fixed connection to the door leaf. One end of the connecting rod is fixedly connected to the connecting block. The adjusting roller is fitted onto the other end of the connecting rod, with one side of the adjusting roller resting against the track beam. The adjusting roller and the first sliding member are offset vertically to clamp the door leaf against the track beam. The upper end of the door leaf is slidably connected to the track beam via the first sliding member, and the connector prevents the door leaf from detaching from the track beam. The adjusting roller and the first sliding member cooperate to clamp and slide on the track beam, effectively preventing the door leaf from swinging to either side under lateral external forces. The first sliding member and the adjusting roller reduce the friction of the door leaf, resulting in more stable operation. Furthermore, the door leaf will not jam under external forces during operation, offering higher stability and greater ease of use. Attached Figure Description

The directional terms used are for the purpose of explaining and understanding this utility model, and are not intended to limit this utility model.

[0036] In the diagram, units with similar structures are represented by the same labels.

[0037] Please refer to Figure 1 , Figure 2In this embodiment, the upper end of the door leaf is slidably connected to the track beam 2 via a first sliding member 33. A connecting member 1 is used to prevent the door leaf from detaching from the track beam 2. The connecting member 1 includes a connecting block 11, a connecting rod 12, and an adjusting roller 13.

The adjusting roller 13 is fitted onto the other end of the connecting rod 12, and one side of the adjusting roller 13 is attached to the track beam 2. The adjusting roller 13 and the first sliding member 33 are offset vertically to clamp the door leaf onto the track beam 2.

[0038] The connecting block 11 can be set as a square structure. The length direction of the connecting block 11 can be set vertically or horizontally, depending on the actual installation space.

[0039] In this embodiment, please refer to Figure 1 The other end of the connecting block 11 is provided with an adjusting screw hole. The connecting rod 12 is a bolt structure, and one end of the connecting rod 12 is threaded to the adjusting screw hole. The connecting rod 12 is connected to an adjusting roller 13 by a bearing, which helps to reduce the frictional resistance when the first door leaf 31 slides, and can also reduce the axial swing of the door leaf on the adjusting roller 13, making the operation more stable.

[0040] Preferably, the connector 1 further includes at least one adjusting nut 14, which is threadedly connected to one end of the connecting rod 12. The adjusting nut 14 is located between the adjusting roller 13 and the connecting block 11, so that the adjusting roller 13 is clamped and fixed between the adjusting nut 14 and the nut of the connecting rod 12. At the same time, by placing adjusting nuts 14 of different sizes or in different numbers, it is easy to adjust the position and size of the adjusting roller 13, which makes the compatibility stronger and the installation and debugging more convenient and quick.

[0041] To improve the stability of the adjusting roller 13, a limiting groove can be provided along its length on the other side of the first mounting plate 21, with the side of the adjusting roller 13 protruding from the connecting rod 12 positioned within the limiting groove.

The first sliding member 33 and the connecting member 1 are staggered vertically, and the first sliding member 33 cooperates with the connecting member 1 to clamp the first door panel 31 onto the first mounting plate 21, effectively preventing the door panel from swinging to both sides due to lateral external forces. The connecting member 1 and the first sliding member 33 allow the first door panel 31 to slide on the first mounting plate 21, resulting in less friction and more stable operation. Moreover, the first door leaf 31 will not jam under the action of external force during operation, which makes it more stable and easier to use.

[0043] In this embodiment, the first sliding member 33 includes a plurality of pulleys 331 and a plurality of connecting shafts 332 spaced apart along the sliding direction.

One end of the second limiting screw 522 is threaded to the second limiting nut 523, and the other end of the second limiting screw 522 passes through the corresponding door leaf in sequence. The slider 521 is threaded to the second clamping piece 524, which is located within the U-shaped groove. The second clamping piece 524 and the second limiting nut 523 fix the slider 521 to the corresponding door leaf, making installation and disassembly more convenient and reducing costs.

[0062] In actual use, the drive motor 41 rotates forward and backward to control the automatic opening and closing of the four door panels. The widths of the first door panel 31, the third door panel 32, the second door panel 32, and the fourth door panel 39 are all the same. When the drive motor 41 rotates forward, the main chain belt 44 synchronously drives the first adjusting seat 34 and the second adjusting seat 36 to move towards each other. The first adjusting seat 34 drives the first chain belt 3142 to rotate, so that the second door panel 32 moves synchronously with the first door panel 31 through the third adjusting seat 311. The second adjusting seat 36 drives the fourth door panel 39 to move synchronously with the third door panel 32 through the second transmission component 37. The first door panel 31 and the third door panel 32 have the same running speed, and the second door panel 32 and the fourth door panel 39 have the same running speed. When the adjacent side of a single first door panel 31 and the third door panel 32 is closed, the other side of the first door panel 31 is adjacent to the side of the second door panel 32 that is close to the third door panel 32, and the second door panel 32 and the fourth door panel 39 are also in the closed position. When the drive motor 41 reverses, the first door leaf 31 and the third door leaf 32 move in opposite directions, and the second door leaf 32 and the fourth door leaf 39 move in opposite directions. The principle is the same as that of the closed state, which can be referred to in the above-mentioned related content. When the door is fully opened, the first door leaf 31 and the second door leaf 32 are aligned, and the third door leaf 32 and the fourth door leaf 39 are aligned.

[0063] This utility model relates to a connector and its corresponding anti-slip door structure. The connector includes a connecting block, a connecting rod, and an adjusting roller. The connecting block is used for fixed connection with the door leaf. One end of the connecting rod is fixedly connected to the connecting block. The adjusting roller is fitted and connected to the other end of the connecting rod, with one side of the adjusting roller abutting against the track beam. The adjusting roller and the first sliding member are offset vertically to clamp the door leaf against the track beam. The upper end of the door leaf is slidably connected to the track beam via the first sliding member, and the connector is used to prevent the door leaf from detaching from the track beam. The adjusting roller and the first sliding member cooperate to clamp and slide on the track beam, which can effectively prevent the door leaf from swinging to both sides under lateral external forces. The first sliding member and the adjusting roller can reduce the friction of the door leaf and make its operation more stable. Moreover, the door leaf will not jam under external forces during operation, resulting in higher stability and greater ease of use.

[0064] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
