Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of outdoor components of prefabricated buildings, and particularly relates to a retractable rigid roof device, which can be used in different places such as fixed buildings, temporary buildings, small convenient facilities, and structures that require retractable roofs. Background Technique
[0002] A retractable roof is a modern building technology that allows the roof to be retracted or extended as needed to adapt to different climate conditions and usage requirements.
[0003] At present, the common retractable roofs include soft ceiling surfaces and rigid ceiling surfaces. The soft ceiling surface is extended by the retraction of cross members; for example, a rainproof tarpaulin, on which the cross-shaped keels are folded, retracted, and extended, and the floor-mounted hanging wheels control the retraction and extension. The rigid ceiling surface usually slides on a guide rail provided on the top end surface of the roof.
[0004] However, the use of the above-mentioned soft ceiling surface results in a large shape due to on-site requirements, and ultimately, a rigid shape cannot be achieved. Moreover, the soft rain canopy top surface may sag and accumulate water in the event of a heavy rain. Over time, it will pose a danger. When the rigid ceiling surface is opened, some of the chute openings of the guide rail will be exposed upward, resulting in the generation of dust and other impurities on the chute, which will ultimately affect the stability of the rigid ceiling surface when sliding on the guide rail and the safety during operation. Summary of the Utility Model
[0005] The utility model provides a retractable rigid roof device, aiming to set the chute opening of the guide rail vertically downward so that the rigid ceiling surface slides on the guide rail, thereby avoiding the appearance of dust and other impurities on the chute due to the exposure of the chute, improving its stability during operation, ensuring safety. In addition, compared with the soft rain canopy top surface, a rigid effect can be achieved, and the situation of sagging and water accumulation can also be avoided.
[0006] The technical problems to be solved by the utility model are achieved by adopting the following technical solutions:

Along the length direction of the guide rail, the bottom edge of the rigid roof panel has a bending part, which corresponds to the opening. A hanging wheel is installed at the bottom of the bending part, and the hanging wheel is rotatably sleeved in the guide rail. A placement groove is formed by the bending part, the side wall of the rigid roof panel, and the top of the rigid roof panel.

When the hanging wheel rolls in place on the guide rail, at this time the second right-angle bending part rotates from along the length direction of the guide rail to along the width direction of the guide rail and is sleeved on the guide rail.
[0017] Preferably, along the length direction of the guide rail, a waist-shaped hole is opened on the side wall of the guide rail, and the second right-angle bending part penetrates through the waist-shaped hole and is sleeved on the guide rail.

Detailed implementation mode
[0040] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.
[0041] As Figure 1-10 shown, a retractable rigid roof device includes a rigid roof panel 1 and a guide rail 3 which is installed on the wall surface where the roof is located (such as bolt fastening or welding) and has a C-shaped track, and the length direction of the top of the outer facade of the wall is used as the length direction of the guide rail 3. The guide rail 3 has a chute with an opening vertically downward. Along the length direction of the guide rail 3, the bottom edge of the rigid roof panel 1 has a bending part, which corresponds to the opening. A hanging wheel 6 is installed at the bottom of the bending part, and the hanging wheel 6 is rotatably sleeved in the guide rail 3. Specifically: the bending part is a first right-angled bending part 101 with a vertical downward direction, and the bottom edge of the first right-angled bending part 101 is parallel to the top plane of the guide rail 3; the first right-angled bending part 101 is provided with a hanging wheel 6 through a fixing rod 9; the hanging wheel 6 is rotatably sleeved in the guide rail 3
[0042] The first right-angled bending part 101, the side wall of the rigid roof panel 1, and the top of the rigid roof panel 1 form a placement groove 2. A metal fulcrum 5 is installed at the top of the placement groove 2. The metal fulcrum 5 abuts against the guide rail 3 installed in the placement groove 2, creating a gap between the top end face of the placement groove 2 and the guide rail 3, and enabling the rigid roof panel 1 to reach balance, facilitating the movement of the rigid roof panel 1 on the guide rail 3.
[0043] A positioning mechanism 8 is provided between the rigid roof panel 1 and the guide rail 3 to limit the movement of the rigid roof panel 1, and the positions where the positioning mechanism is installed on the rigid roof panel 1 and the guide rail 3 are regarded as the rear end. Specifically: The positioning mechanism 8 is a limiting rod 81 and a nut 82. The limiting rod 81 is inserted vertically upward into the guide rail 3 along the bottom of the first right-angled bending part 101 and from the opening on the guide rail 3 (specifically: along the vertical direction, a second right-angled bending part 811 is provided on the limiting rod 81, and the second right-angled bending part 811 is sleeved on the guide rail 3); and the nut 82 is threadedly sleeved on the limiting rod 81, and the top surface of the nut 82 abuts against the bottom surface of the first right-angled bending part 101 to fix the first right-angled bending part 101 and the guide rail 3 (specifically: when the hanging wheel 6 rolls in place on the guide rail 3, at this time, the second right-angled bending part 811 rotates from the length direction of the guide rail 3 to the width direction of the guide rail 3 (it should be noted that the direction from the outer facade of one wall to the outer facade of the other parallel wall is regarded as the width direction of the guide rail 3); more specifically: along the length direction of the guide rail 3, a waist-shaped hole 10 is opened on the side wall of the guide rail 3, and the second right-angled bending part 811 passes through the waist-shaped hole 10 and is sleeved on the guide rail 3;
[0044] It should be noted that on a single guide rail 3, there are two waist-shaped holes 10, and they are respectively located at the corresponding positions on the guide rail 3 when the rigid roof panel 1 completely covers the roof or is opened).
[0045] A locking mechanism is also installed between the rigid roof panel 1 and the guide rail 3 to make the rigid roof panel 1 form an inclined slope, so that the impurities on the rigid roof panel 1 drain along the slope; the positions where the locking mechanism is installed on the rigid roof panel 1 and the guide rail 3 are regarded as the front end. Specifically: The locking mechanism is a bolt 7. Along the vertical direction, the bolt 7 is screwed into the bottom edge of the guide rail 3 from the bottom edge of the first right-angled bending part to fix the first right-angled bending part 101 and the guide rail 3, making the rigid roof panel 1 form a drainage slope relative to the guide rail 3 at the front end. Specifically, a threaded hole 107 is opened on the bottom edge of the first right-angled bending part 101, and after the bolt 7 is screwed into the threaded hole 107, it is then tightened on the guide rail 3;
[0046] Screw the bolt 7 at the end of the rigid roof panel 1 into the guide rail 3, raising the height of the rear end of the rigid roof panel 1, making the rigid roof panel 1 form a forward drainage slope, and strengthening the fastening degree of the rigid roof panel 1.
[0047] The metal fulcrum 5 abuts against the guide rail 3, creating a gap between the top surface of the placement groove and the guide rail 3, achieving balance at the front and rear ends, and facilitating the movement of the rigid roof panel 1 on the guide rail 3.
[0048] Plug heads 11 are provided at both ends of the guide rail 3. The plug heads 11 are used to seal the ends of the guide rail 3 and prevent the hanging wheels 6 from slipping out of the guide rail 3.
[0049] Both the first right-angled bending portion 101 and the second right-angled bending portion 811 are L-shaped structures. Among them, the L-shaped structure on the first right-angled bending portion 101 is integrally formed with the rigid roof panel 1.
[0050] The working principle of the present utility model is as follows:
[0051] First, with the assistance of the guide rail 3, the rigid roof panel 1 moves on the roof. That is, the hanging wheels 6 connected to the rigid roof panel 1 roll on the guide rail 3. And when rolling, at this time, the second right-angled bending portion 811 is placed along the length direction of the guide rail 3 (when the rigid roof panel 1 extends, rotate the limit rod 81 and turn the second right-angled bending portion 811 into the guide rail 3).
[0052] Next, when the rigid roof panel 1 covers the roof, that is, when the hanging wheel 6 at the front end contacts the plug head 11, use the bolt 7 to fix the rigid roof panel 1 and the guide rail 3, fixing the front end of the rigid roof panel 1, and by adjusting the bolt 7, making the front end have an inclined slope relative to the rear end.
[0053] Then, turn the second right-angled bending portion 811 from along the length direction of the guide rail 3 to along the width direction of the guide rail 3 (that is, when the rigid roof panel 1 is retracted, rotate the limit rod 81 and turn the second right-angled bending portion 811 into the waist-shaped hole 10 to limit the forward extension of the rigid roof panel 1), and sleeve it on the guide rail 3 through the waist-shaped hole 10, and tighten the nut 82 to fix the rear end of the rigid roof panel 1.
[0054] At this point, the rigid roof panel 1 completely covers the roof.
[0055] It should be noted that except for turning the second right-angled bending portion 811 on the limit rod 81 into another waist-shaped hole 10 (here it should be noted that one waist-shaped hole 10 and the other waist-shaped hole 10 are arranged along the length direction of the guide rail 3, and one waist-shaped hole 10 is at the front end and the other waist-shaped hole 10 is at the rear end), the process of the rigid roof panel 1 covering the roof is the reverse process of opening the rigid roof panel 1 on the roof, which will not be elaborated in detail in this text.
[0056] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and without departing from the spirit and scope of the present utility model, various changes and improvements will occur to the present utility model, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
