Description

Technical Field

[0001] This utility model relates to the field of mobile telescopic building technology, and in particular to a sliding track structure for mobile, telescopic, and variable space buildings such as telescopic sunrooms, mobile swimming pool covers, and openable and retractable stadium roofs. Background Technology

[0002] Mobile retractable buildings are architectural structures that can be flexibly expanded and retracted. They consist of multiple stacked functional units that move between each other via guide rails and pulleys, thus enabling the overall structure to expand and contract. These buildings come in various forms and are commonly found in retractable sunrooms, movable swimming pool covers, retractable stadium roofs, and various mobile frame systems.

[0003] Currently, most of the pulley travel mechanisms of such buildings still adopt single-point support or simple guidance design. Under extreme load conditions such as strong winds (such as typhoon weather), the building units are prone to lateral swaying and even derailment risk, which seriously affects the safety and durability of the structure. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, this utility model provides a non-derailment rail structure with multi-directional limiting during gliding. This structure is stable and firm, and has the effects of resisting typhoons, preventing shaking and derailment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-directional limiting anti-derailment rail structure is provided for sliding, comprising a guide rail unit and a building unit movably mounted on the guide rail unit. The building unit is characterized by having a walking component at its bottom, the walking component comprising:

[0006] The first pulley is vertically arranged, and the guide rail unit is correspondingly provided with a first guide rail. The top side of the first pulley is rolled and fitted on the bottom side of the first guide rail.

[0007] The second pulley is horizontally arranged, and the guide rail unit is correspondingly provided with a second guide rail. The left and right sides of the second pulley are rolled and fitted on the inner walls of the left and right sides of the second guide rail.

[0008] The third pulley is vertically arranged, and a corresponding third guide rail is provided on the guide rail unit. The bottom side of the third pulley is rolled in a rolling fit on the top side of the third guide rail.

[0009] As a further improvement of this utility model, the first pulley is provided in at least one pair, with the two pulleys in each pair of the first pulleys located on the left and right sides of the bottom of the building unit respectively, and the first guide rail is provided with two tracks on the left and right sides accordingly; the second pulley is provided in at least one pair, with the two pulleys in each pair of the second pulleys located on the left and right sides of the bottom of the building unit respectively, and the second guide rail is provided with two tracks on the left and right sides accordingly; the third pulley is located between the left and right sides of the bottom of the building unit.

[0010] As a further improvement of this utility model, the walking assembly further includes a first walking member and a second walking member arranged front to back, the first pulley and the second pulley are arranged on the first walking member, and the third pulley is arranged on the second walking member.

[0011] As a further improvement of this utility model, the first pulley is respectively arranged on the left and right sides of the first traveling member; the second pulley is respectively arranged on the left and right sides of the first traveling member; the first pulley and the second pulley on the same side are arranged with a front-to-back interval;

[0012] As a further improvement of this utility model, the third pulley is disposed on the bottom side of the second traveling member.

[0013] As a further improvement of this utility model, it also includes an adjustable screw, through which the first traveling member is height-adjustably connected to the bottom of the building unit.

[0014] As a further improvement of this utility model, brushes are respectively provided on the front and rear sides of either the first walking member or the second walking member.

[0015] As a further improvement of this utility model, the third pulley is provided in at least one pair, with two pulleys in each pair of third pulleys arranged left and right and located on the middle side of the bottom of the building unit, and the third guide rail is provided with two tracks on the left and right sides respectively.

[0016] As a further improvement of this utility model, the rolling surface of the third pulley is configured as an arc-shaped groove, and the third guide rail is configured as a corresponding arc-shaped protrusion.

[0017] The beneficial effects of this utility model are as follows: In this utility model, the first pulley is vertically arranged, and its top side rolls in cooperation with the first guide rail on the upper side, which can stably transfer the vertical load to the first guide rail, thereby significantly improving the structure's pull-out resistance and effectively reducing the risk of pulley derailment and building unit overturning; the second pulley is horizontally arranged and rolls tightly with the inner walls of the left and right sides of the second guide rail, which can effectively suppress the lateral swaying of the building unit under strong wind conditions, improving the overall structural stability and wind resistance; the third pulley is used as a load-bearing wheel to support and drive the building unit to move, and the overall load-bearing is stable and reliable. This utility model, through the multi-directional force design of the first pulley to prevent derailment, the second pulley to prevent swaying, and the third pulley to bear the load, optimizes the load distribution, which can significantly improve the building unit's ability to resist typhoons, prevent swaying, and prevent derailment. The structure is stable and firm, with high safety, and can reduce component wear caused by local stress concentration, extending the service life of the pulley traveling structure.

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] like Figure 1-7As shown, a sliding anti-derailment rail structure with multi-directional limiting includes a guide rail unit 1 and a building unit 2 movably mounted on the guide rail unit 1. The building unit 2 can be a retractable sunroom, a movable swimming pool cover, an openable stadium roof, or various movable frames. In this embodiment, the building unit 2 is a side panel of a retractable sunroom. A walking assembly is installed at the bottom of the building unit 2, comprising a first walking member 3 and a second walking member 4 arranged at intervals along the moving direction of the building unit 2. Both the first walking member 3 and the second walking member 4 are screwed to the bottom of the building unit 2. The first walking member 3 and the second walking member 4 drive the building unit 2 to move on the guide rail unit 1, thereby achieving the retraction and extension of the building unit 2. The specific structure is as follows:

[0028] The first traveling member 3 is equipped with multiple pairs of first pulleys 31 and multiple pairs of second pulleys 32. Two first pulleys 31 and two second pulleys 32 in each pair are respectively located on the left and right sides of the first traveling member 3. The first pulleys 31 and second pulleys 32 on the same side are arranged at intervals. Specifically: the positions of the first pulleys 31 on the left and right sides correspond to the left and right sides of the bottom of the building unit 2. The guide rail unit 1 is correspondingly equipped with two left and right first guide rails 11. The first pulleys 31 are vertically positioned, with their top sides rolling against the bottom side of the first guide rail 11 to transmit vertical loads and prevent the building unit 2 from derailing or tilting upwards. The positions of the second pulleys 32 on the left and right sides correspond to the left and right sides of the bottom of the building unit 2. The guide rail unit 1 is correspondingly equipped with two left and right second guide rails 12. The second pulleys 32 are horizontally positioned, with their left and right sides rolling against the inner walls of the left and right sides of the second guide rail 12 to limit lateral displacement, reduce lateral sway, and enhance wind resistance stability. The first traveling component 3 is height-adjustably connected to the bottom of the building unit 2 via an adjustable screw 33. The installation height of the first traveling component 3 can be finely adjusted by rotating the adjustable screw 33 to ensure the matching accuracy between each pulley and the guide rail.

[0029] The second traveling member 4 has multiple pairs of third pulleys 41 on its bottom side. Two of the third pulleys 41 in each pair are arranged in a left-right direction and located between the left and right sides of the bottom of the building unit 2. In this embodiment, they are preferably located in the middle. The guide rail unit 1 is correspondingly provided with two left and right third guide rails 13. The bottom side of the third pulley 41 and the top side of the third guide rail 13 form a rolling engagement to support and drive the building unit 2 to move smoothly. The rolling surface of the third pulley 41 is machined into an arc-shaped groove, and the third guide rail 13 is correspondingly set as an arc-shaped protrusion. The movement stability is further improved through the cooperation of the arc-shaped structure.

[0030] The first guide rail 11, the second guide rail 12 and the third guide rail 13 mentioned above are all set along the moving direction of the building unit 2.

[0031] Brushes (not shown in the figure) are installed on both the front and rear sides of the first traveling member 3 and the second traveling member 4. The bristles of the brushes are in contact with the surface of the guide rail unit 1, which can clean the dust and impurities on the surface of the guide rail during the movement of the building unit 2 and improve the smoothness of sliding.

[0032] The working process of the above-mentioned pulley traveling structure is as follows: When the building unit 2 moves telescopically, the third pulley 41 rolls along the third guide rail 13 and bears the main load-bearing function; the first pulley 31 cooperates with the top and bottom of the first guide rail 11 to form a vertical limit, effectively transmitting the vertical load and preventing the building unit 2 from being pulled upward or derailed; the second pulley 32 cooperates with the left and right inner walls of the second guide rail 12 to form a lateral limit, suppressing the lateral swaying of the building unit 2; the three work together to significantly improve the wind resistance stability and safety of the structure while ensuring the flexibility of movement.

[0033] The above-described embodiments are merely illustrative of this utility model. Any equivalent embodiments made by those skilled in the art without departing from the technical features disclosed in this utility model, and without departing from the technical features of this utility model, shall still fall within the scope of the technical features of this utility model.
