Description

Technical Field

[0001] This utility model relates to the field of sliding suspension door tracks, specifically to an optimized structure for sliding section sliding suspension door tracks. Background Technology

[0002] Segmented sliding gates are commonly used entrance and exit devices in modern industrial and civil applications. Their multi-segment sliding opening and closing design allows for flexible opening and closing of large-span passageways. Furthermore, their trackless, suspended nature gives them significant advantages in space utilization and operational convenience, making them widely used in factory parks, logistics hubs, and upscale residential communities. Their core operation relies on a sliding track structure; the precision of the fit between the track and the gate directly determines the smoothness, stability, and lifespan of the gate's sliding motion.

[0003] Traditional tracks often employ a planar contact design, resulting in a large contact area between the door and the track, leading to significant frictional resistance. This is particularly problematic when the door is starting or under heavy load, making it prone to sliding and jamming. Furthermore, the planar contact structure is insufficient to effectively constrain the lateral displacement of the door. Under the influence of external forces such as wind and ground vibrations, the door is prone to swaying, causing accelerated wear at the track-door mating points, further increasing resistance and affecting smooth operation. Moreover, traditional tracks are often welded or integrally fixed to the door. When localized wear on the track necessitates replacement, the entire door must be disassembled or the original structure damaged, making the operation complex, time-consuming, and increasing maintenance costs.

[0004] Therefore, it is necessary to invent an optimized sliding structure for a segmented sliding suspended door track to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an optimized sliding structure for a segmented sliding suspended door track. By setting a V-shaped guide groove and a guide wheel in line contact, and a T-shaped connector and a slot in a modular connection, it can solve the problems in the prior art, such as high frictional resistance and easy jamming due to planar contact of traditional tracks, insufficient lateral constraint causing door shaking and increased wear, and complex track and door fixing methods leading to inconvenient disassembly and maintenance and high costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optimized sliding structure for a segmented sliding suspended door track, comprising...

[0007] The mounting base is used to support the entire track sliding structure. The upper inner wall of the mounting base is provided with multiple sets of guide wheels, and the front and rear sides of the mounting base are provided with auxiliary wheels.

[0008] The door body has a fixed frame fixedly connected to its lower part. A sliding groove is provided at the lower part of the fixed frame. A guide rail mechanism is provided on the inner wall of the sliding groove. A guide wheel contacts the outer side of the guide rail mechanism. The guide rail mechanism includes multiple sets of slots opened on the upper and lower inner walls of the sliding groove. A connector is inserted into the inner wall of the slot. A slide rail is fixedly connected to the outer side of the connector. Multiple sets of slide rails are provided. A guide groove is opened on the opposite side of two sets of slide rails. The guide wheel rolls on the inner wall of the guide groove.

[0009] Preferably, the door body further includes a fixing plate, which is fixedly connected to the right side of the slide rail by fixing bolts, and the fixing plate is also fixedly connected to the right side of the door body by fixing bolts.

[0010] Preferably, the inner wall at the center of the guide groove is provided with a guide groove, and the outer side of the auxiliary wheel contacts the inner side of the slide groove.

[0013] Preferably, the fixing plate has a V-shaped groove of the same shape as the guide groove on the side near the guide groove.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This utility model uses a T-shaped connector to engage with a T-shaped slot on the inner wall of the slide rail, allowing for the installation or replacement of the slide rail without the need for complex tools, greatly simplifying the assembly process. The anti-loosening feature of the T-shaped structure ensures that the slide rail will not loosen during long-term use, improving structural reliability. At the same time, the fixing plate connects the slide rail and the door body simultaneously with the fixing bolts, which not only strengthens the connection strength between the slide rail and the door body, but also facilitates the separate disassembly of the slide rail for maintenance, reducing later maintenance costs.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1 - Figure 3 The diagram shows an optimized sliding structure for a segmented sliding suspended door track, including a mounting base 1 and a door body 4.

[0024] Mounting seat 1 is used to support the entire track sliding structure, bear the weight of the door body 4 and related components, and provide an installation reference for guide wheels 2 and auxiliary wheels 3. Multiple sets of guide wheels 2 are provided on the upper inner wall of mounting seat 1, and auxiliary wheels 3 are provided on the front and rear sides of mounting seat 1.

[0025] The main structure of the sliding suspended door is the door body 4. A main gantry frame is set on the outside of the door body 4, and a transmission mechanism is set on the inner wall of the main gantry frame. The transmission mechanism drives the door body 4 to move by meshing with the rack at the bottom of the fixed frame 5. The fixed frame 5 is fixedly connected to the lower part of the door body 4 to connect the door body 4 and the guide rail mechanism 7 into a whole. The lower part of the fixed frame 5 has a sliding groove 6, which serves as the mounting carrier for the guide rail mechanism 7. Its inner wall provides a contact surface for the auxiliary wheel 3, which works with the guide wheel 2 to achieve multi-directional limiting of the door body 4. The guide rail mechanism 7 is set on the inner wall of the sliding groove 6. The guide wheel 2 contacts the outer side of the guide rail mechanism 7. The guide rail mechanism 7 includes multiple sets of slots 71 opened on the upper and lower inner walls of the sliding groove 6. The slots 71 are T-shaped and cooperate with the T-shaped plug 73 to achieve quick positioning and installation of the sliding rail 72 and ensure reliable connection.

[0026] like Figure 2 and Figure 3As shown, a connector 73 is inserted into the inner wall of the slot 71. The connector 73 is T-shaped and serves to connect the slide rail 72 and the fixed frame 5. The T-shaped structure design ensures quick assembly and disassembly of the slide rail 72 and improves structural stability. The slide rail 72 is fixedly connected to the outer side of the connector 73. The long strip structure fixed to the outer side of the connector 73 forms the track foundation for the sliding of the door 4. The guide groove 74 cooperates with the guide wheel 2 to directly guide the sliding direction of the door 4. There are multiple sets of slide rails 72. The guide groove 74 is opened on the opposite side of two sets of slide rails 72. The guide wheel 2 rolls on the inner wall of the guide groove 74. The guide groove 74 is V-shaped. The guide wheel 2 rolls with the guide groove 74. The V-shaped design replaces the traditional surface contact with line contact, which greatly reduces frictional resistance and forms a two-way limit on the guide wheel 2 to counteract the lateral sway of the door 4 and ensure the accurate movement trajectory of the door 4.

[0027] like Figure 2 and Figure 3 As shown, the door body 4 also includes a fixing plate 76. The fixing plate 76 is fixedly connected to the right side of the slide rail 72 by fixing bolts 77. The fixing plate 76 is also fixedly connected to the right side of the door body 4 by fixing bolts 77. The cooperation between the fixing plate 76 and the fixing bolts 77 strengthens the connection strength between the slide rail 72 and the door body 4, prevents the slide rail 72 from loosening during long-term use, and facilitates the separate disassembly of the slide rail 72 for maintenance, improving the convenience of later maintenance. The fixing plate 76 has a V-shaped groove with the same shape as the guide groove 74 on the side near the guide groove 74. The inner wall of the center of the guide groove 74 has a guide groove 75 to guide the water and dust that enter the guide groove 74. The outer side of the auxiliary wheel 3 contacts the inner side of the slide groove 6.

[0028] The working principle of this utility model is as follows: The mounting base 1 is fixed to the ground and serves as the supporting base for the entire structure. Multiple sets of guide wheels 2 on the upper inner wall of the base 1 form a rolling engagement with the guide rail mechanism 7 at the bottom of the door body 4. When the door body 4 is started, the fixed frame 5 moves synchronously with the door body 4. The slide rail 72 in the guide rail mechanism 7 is connected to the slide groove 6 of the fixed frame 5 through the plug-in 73, which drives the guide groove 74 to roll along the guide wheel 2.

[0029] The guide groove 74 is designed in a V-shape, forming a line contact with the guide wheel 2. Compared with the traditional planar contact, this significantly reduces frictional resistance, making the door 4 slide more smoothly. At the same time, the V-shaped structure provides bidirectional restraint for the guide wheel 2, which can counteract the lateral displacement of the door 4 caused by wind or ground micro-vibrations, ensuring precise sliding trajectory. The guide groove 75 in the center of the guide groove 74 can guide the discharge of water and dust that enters the groove during sliding, preventing foreign objects from accumulating and causing the guide wheel 2 to jam, thus ensuring smooth long-term operation.

[0030] When the slide rail 72 needs to be replaced, simply remove the fixing bolts 77 on the fixing plate 76 to release the rigid connection between the slide rail 72 and the door body 4; then pull out the T-shaped connector 73 along the axial direction of the slot 71, and the slide rail 72 can be removed from the slide groove 6 as a whole without damaging other parts, thus achieving modular separation.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
