[0003] Generally, a connection structure with a slide rail is provided at the top end of the door body of the hangar door, and a roller structure is generally provided at the bottom.

[0004] Due to the large span of the hangar and the large load of the structural dead weight, after the roller structure at the bottom of the hangar door body is used for a period of time, it needs to be replaced and maintained. The traditional roller structure is not convenient for quick replacement and is inconvenient to use. Content of the Utility Model

[0005] The purpose of the embodiment of the utility model is to provide a side-turning hangar door which is convenient for replacing rollers, aiming at solving the technical problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions.

[0028] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] The following describes the specific implementation of the present utility model in detail with specific embodiments.

[0030] As Figure 1 shown, in an embodiment of the present utility model, a side - rotating hangar door with rollers that are easy to replace is provided. The hangar door includes a plurality of door bodies 100, and adjacent door bodies 100 are connected by a plurality of hinges.

[0031] Further, please continue to refer to Figure 1 , the side - rotating hangar door with rollers that are easy to replace further includes an upper track 200 and a concrete floor 300. Among them, the upper track 200 is arranged on the top beam of the hangar door opening, and the concrete floor 300 is located on the ground of the hangar door opening; a lower track 301 is arranged on the concrete floor 300, and the lower track 301 is used to support the roller mechanism.

[0032] Among them, a support top block 101 that cooperates with the upper track 200 is arranged at the top of the door body 100.

[0033] Furthermore, the side - rotating hangar door with rollers that are easy to replace provided by the present disclosure further includes a roller mechanism, and the roller mechanism includes a roller 102 and a support leg 105.

[0034] Preferably, as shown in Figure 2 and Figure 3 shown, the roller 102 is arranged on the roller frame 106, the support leg 105 is arranged through the top of the roller frame 106, and the support leg 105 is rotatably connected to the top of the roller frame 106 by a damping structure;

[0035] Furthermore, in the embodiment of the present disclosure, the bottom end of the support leg 105 has an adjusting cap 107, and the adjusting cap 107 is a polygonal structure, which is convenient for driving the support leg 105 to rotate a certain angle when the adjusting cap 107 is screwed.

[0036] Furthermore, in the embodiment of the present disclosure, a support groove 108 matching the support leg 105 is provided at the bottom of the door body 100;

[0037] The outer circumferences of the upper parts of the support legs 105 respectively have a flat surface part 109 and an arc surface part 110, and a plurality of limiting grooves 115 are equidistantly arranged along the surface of the arc surface part 110.

[0038] A support block 104 is further arranged on the outer wall of the top of the door body 100, and a limiting block 114 is elastically supported on the support block 104. The limiting block 114 is matched with the limiting groove 115. When the upper part of the support leg 105 extends into the support groove 108, the limiting block 114 is pressed against the limiting groove 115 under the elastic support.

[0039] Preferably, the lower surface of the limiting groove 115 is an inclined surface structure; the lower surface of the limiting block 114 is also an inclined surface structure, that is, the inclined surface of the limiting block 114 faces the opening direction of the support groove 108. Based on this structure, when the upper part of the support leg 105 extends into the support groove 108, the support leg 105 abuts against the inclined surface of the limiting block 114, which will push the limiting block 114 to retract into the interior of the support block 104, that is, it does not affect the upper part of the support leg 105 from extending into the support groove 108;

[0040] On the contrary, when the support leg 105 does not rotate, since the upper surface of the limiting block 114 is a flat surface structure and the upper surface of the limiting groove 115 is a flat surface structure, the support leg 105 cannot be pulled out of the support groove 108.

[0041] Correspondingly, when replacing the roller 102 of the hangar door in the embodiment of the present disclosure, a tool such as a wrench is used to rotate the adjusting cap 107 to drive the support leg 105 to rotate. After the support leg 105 rotates a certain angle, the limiting block 114 can be rotated from the side of the arc surface part 110 to the side of the flat surface part 109. Since the flat surface part 109 is a flat surface structure, at this time, the support leg 105 can be smoothly pulled out of the support groove 108.

[0042] Preferably, the limiting block 114 is fixedly supported and installed on the slider 113. The slider 113 is supported by an elastic member 112 and disposed within the support block 104. Herein, the elastic member 112 can be a spring or a spring piece, without specific limitation.

[0043] Further, as Figures 1 - 3 shown, a limiting through hole 111 is formed on the flat portion 109 at the upper part of the supporting leg 105. A limiting pin 103 adapted to the limiting through hole 111 is installed at the bottom of the door body 100. After the supporting leg 105 is inserted into the supporting groove 108 to achieve the clamping of the supporting leg 105, the limiting pin 103 is inserted into the limiting through hole 111 to prevent the supporting leg 105 from rotating independently.

[0044] From the above structural description, it can be seen that when maintaining and replacing the roller 102 in the embodiment of the present disclosure, first, the limiting pin 103 is pulled out from the limiting through hole 111, and then a tool such as a wrench is used to turn the adjusting cap 107, so that the supporting leg 105 rotates by a certain angle. After the supporting leg 105 rotates by a certain angle, the limiting block 114 that originally abuts against the limiting groove 115 correspondingly changes to the limiting block 114 abutting against the flat portion 109. Since the flat portion 109 is an integral flat structure, the limiting block 114 abutting against the flat portion 109 does not affect the extraction of the supporting leg 105 from the supporting groove 108. At this time, the disassembly process of the roller mechanism from the bottom of the door body 100 is completed.

[0045] The above solutions are only illustrations of a preferred example, but not limited thereto. When implementing the present utility model, appropriate substitutions and / or modifications can be made according to the needs of users.

[0046] The number of devices and the processing scale described here are used to simplify the description of the present utility model. The applications, modifications, and variations of the present utility model are obvious to those skilled in the art.

[0047] Although the implementation solutions of the present utility model are disclosed as above, they are not limited to only the applications listed in the specification and the implementation manners. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the illustrated examples described herein.
