Description

Technical Field

[0001] This utility model relates to the field of linear gate technology, and in particular to a compact sliding telescopic linear gate. Background Technology

[0002] Linear doors are a type of door that opens and closes using linear motion. They are commonly found in industrial plants, logistics warehouses, commercial spaces, and high-end residences. Their core feature is that a linear drive system (such as a motor, gears, chain, or belt) moves the door horizontally along a track, enabling fast and smooth opening and closing.

[0003] Traditional linear gate designs use a snap-fit ​​structure to connect adjacent gate sections. Specifically, independent snap-fit ​​components are installed on the outside of the gate. When the equipment is running, these snap-fit ​​components are used to achieve lateral limiting and trajectory constraint. However, this connection method is relatively loose, and the gate is prone to relative swaying during operation. Especially when encountering lateral wind pressure, the gap between the gate sections will cause high-frequency impact noise due to vibration. The loose connection mechanism causes the gate's running trajectory to deviate periodically, making it impossible to maintain a strictly linear motion state and affecting the stability of the equipment operation.

[0004] To address this, a compact sliding telescopic linear gate is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a compact sliding telescopic linear door to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compact sliding telescopic linear gate, comprising four gate bodies arranged sequentially, each gate body having a first slide rail and a second slide rail; each gate body having a connecting assembly for connecting adjacent gate bodies, maintaining the smoothness of sliding between gate bodies and preventing excessive noise, the connecting assembly including a mounting base on the gate body, a rotating shaft rotatably connected to the mounting base, a support fixedly connected to the rotating shaft, and a rubber wheel on the support.

[0007] Preferably, the mounting base is provided with a plurality of screw holes, and a screw rod is provided in the screw holes. The screw rod passes through the door body and is threadedly connected to the screw hole. Each door body is provided with a removable panel. After the panel is removed, the screw rod between the door body and the screw hole can be removed.

[0008] Preferably, a fitting block is fixedly connected to the support platform, and a fitting groove adapted to the fitting block is opened on the rubber wheel, and the fitting block and the fitting groove mesh with each other.

[0009] Preferably, the mounting base is located in the first slide rail and the second slide rail, and the rubber wheel is rotatably connected in the first slide rail and the second slide rail.

[0010] Preferably, a pressing rod is slidably connected to the rotating shaft, a pulley is fixedly connected to the pressing rod, an insert rod is slidably connected to the fitting block, and an insertion port adapted to the insert rod is opened in the rubber wheel.

[0011] Preferably, a steel wire rope is fixedly connected between the insertion rod and the pressing rod, and the steel wire rope is slidably connected to the pulley; a spring is fixedly connected between the insertion rod and the fitting block.

[0012] Preferably, both the first and second slide rails are provided with a retrieval slot, and the door body is provided with a removable panel.

[0013] The beneficial effects of this utility model are: This invention, through the installation of connecting components, enables the rubber wheels of the linear gate to roll tightly within the first and second slide rails as the gate panels slide open. This means the gate panels are tightly connected by the rubber wheels, eliminating any gaps. Consequently, high-frequency impact noise caused by gaps is prevented during gate movement. Compared to traditional connectors, this significantly reduces noise. Furthermore, the rubber wheels exhibit elastic deformation and a low elastic modulus during rolling, effectively absorbing and dispersing the impact force. This buffering effect further reduces noise generated during collisions. Simultaneously, the movement path of the rubber wheels within the first and second slide rails is restricted, preventing periodic deviations in their trajectory and maintaining the stability of the equipment during operation.

[0014] This invention features a pressing rod that, when pressure is applied, pulls a steel wire rope to disengage the insert rod from the socket, facilitating the removal and replacement of the rubber wheel from the support platform. Simultaneously, releasing the pressing rod causes the spring's reaction force to re-enter the socket, maintaining the rubber wheel's stable position and completing the replacement. Therefore, the rubber wheel's easy-to-insert structure makes replacement more convenient during long-term wear and tear. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0020] As shown in Figure 1 Figure 8 As shown in the figure, a specific embodiment of this utility model provides a compact sliding telescopic linear gate, including a gate body 1, of which there are four gate bodies 1 arranged in sequence. The gate body 1 is provided with a first slide rail 2 and a second slide rail 3. The gate body 1 is provided with a connecting component, which is used to connect two adjacent gate bodies 1, maintain the smoothness of sliding between the gate bodies 1, and prevent excessive noise. By setting the connecting component, the gate bodies 1 will not frequently cause impact noise during the gradual unfolding process, and maintain the stability during the moving and unfolding process, so that the gate bodies 1 can move in a straight line. The connecting component includes a mounting base 4 provided on the gate body 1, a rotating shaft 5 rotatably connected to the mounting base 4, a support platform 6 fixedly connected to the rotating shaft 5, and a rubber wheel 7 provided on the support platform 6.

[0021] like Figures 1 to 4As shown, specifically, the mounting base 4 has several screw holes 8, each containing a screw 9. The screw 9 passes through the door body 1 and is threadedly connected to the screw hole 8. Each door body 1 has a removable panel 901. After removing the panel 901, the screw 9 between the door body 1 and the screw hole 8 can be removed. A fitting block 10 is fixedly connected to the support 6, and a fitting groove 11 adapted to the fitting block 10 is opened on the rubber wheel 7. The fitting block 10 and the fitting groove 11 mesh with each other. The mounting base 4 is located in the first slide rail 2 and the second slide rail 3, and the rubber wheel 7 is rotatably connected in the first slide rail 2 and the second slide rail 3. The mounting base 4 is installed on the door body 1 and located within the first slide rail 2 and the second slide rail 3, allowing the door body 1 to gradually open. As the door bodies 1 move relative to each other, the mounting base 4 slides within the first slide rail 2, thus moving the rubber wheel 7. Since the rubber wheel 7 is rolled along the first slide rail 2, it continuously rubs and rolls within the first slide rail 2 during movement. That is, as the mounting base 4 moves within the first slide rail 2, the rubber wheel 7 continuously rolls. When the rubber wheel 7 rolls inside the first slide rail 2, it is in close contact with its inner wall, with no gap between them, thereby allowing the door body 1 to... There are no gaps between them, so there will be no high-frequency impact noise caused by gaps during movement. Compared with traditional connectors, the noise is greatly reduced. Furthermore, the rubber wheel 7 is made of rubber, which, when in rolling contact with the first slide rail 2, exhibits elastic deformation and a low elastic modulus, effectively absorbing and dispersing the impact force during rolling. This buffering effect further reduces the noise generated during collision contact. Simultaneously, the movement of the rubber wheel 7 between the first slide rails 2 is restricted, and its path follows the first slide rail 2, thus limiting the sliding path between the door panels 1 and preventing noise from escaping. The movement trajectory deviates periodically, thus maintaining the stability of the equipment during operation. In the entire device, there are four sets of door bodies 1. Each set of door bodies 1 is equipped with mounting seats 4 and rubber wheels 7 at both ends. When the four sets of door bodies 1 are connected and installed from front to back, the rubber wheels 7 on the right mounting seat 4 of the rear door body 1 are connected to the second slide rail 3 in the front door body 1, while the rubber wheels 7 on the left mounting seat 4 are connected to the first slide rail 2 in the rear door body 1. The door bodies 1 are stacked and installed from front to back according to this pattern.

[0022] like Figures 5 to 8As shown, specifically, a pressing rod 12 is slidably connected to the rotating shaft 5, and a pulley is fixedly connected to the pressing rod 12. An insert rod 13 is slidably connected to the fitting block 10. A socket 14 adapted to the insert rod 13 is opened in the rubber wheel 7. Both the first slide rail 2 and the second slide rail 3 are provided with a take-out groove 17. When the rubber wheel 7 needs to be replaced due to aging or wear after long-term use, since the installation of the panel 901 adopts a conventional connection method, it is connected to the door body 1 by screws. After turning and removing the screws, the panel 901 can be removed. By removing the panel 901 and turning the screw 9 to remove the mounting base 4 from the door body 1, the two doors can be separated. Moving the door body 1 allows the two doors to be separated. After the device is misaligned, the mounting base 4 is moved downwards to a position corresponding to the extraction slot 17, allowing it to be removed outwards through the extraction slot 17. A pressing rod 12 is slidably connected in the rotating shaft 5, and a pulley is fixedly connected in the pressing rod 12. An insert rod 13 is slidably connected on the fitting block 10. An insertion port 14 adapted to the insert rod 13 is opened in the rubber wheel 7. A steel wire rope 15 is fixedly connected between the insert rod 13 and the pressing rod 12, and the steel wire rope 15 is slidably connected to the pulley. A spring 16 is fixedly connected between the insert rod 13 and the fitting block 10. After removing the mounting base 4, the pressing rod 12 is pressed downwards, causing the pressing rod 12 to pull the steel wire rope 15 downwards in the rotating shaft 5. At this time, the steel wire rope... The pull rope 15, under tension, pulls the insert rod 13 to disengage it from the insertion port 14 in the rubber wheel 7. The spring 16, under pressure, contracts and generates a reaction force. After the insert rod 13 disengages from the insertion port 14, the rubber wheel 7 can be removed upwards. The rubber wheel 7 is removed from the support 6, and the interlocking block 10 and the interlocking groove 11 separate. After removing the rubber wheel 7, a new rubber wheel 7 is installed on the support 6, so that the interlocking groove 11 of the rubber wheel 7 re-engages with the interlocking block 10. Then, the pressing rod 12 is released. At this time, under the reaction force of the spring 16, the insert rod 13 is pushed into the insertion port 14. The movement of the insert rod 13 pulls the steel wire pull rope 15, causing the pressing rod 12 to move upwards and reset in the rotating shaft 5. The engagement with the socket 14 keeps the rubber wheel 7 in a stable and limited position on the support 6, preventing it from moving upwards. At the same time, the engagement between the interlocking block 10 and the interlocking groove 11 allows the rubber wheel 7 to rotate synchronously with the interlocking block 10 when rolling, preventing friction caused by asynchronous rotation from accelerating the wear and aging of the rubber wheel 7. The entire device makes it simple and convenient to replace the rubber wheel 7. Pushing the pressing rod 12 allows the rubber wheel 7 to be quickly removed and replaced. After the rubber wheel 7 is replaced, the mounting base 4 is placed into the first slide rail 2 through the removal groove 17, and the mounting base 4 is reinstalled into the door body 1 by the screw 9.
