Description

Technical Field

[0001] This utility model relates to the field of retractable gate accessories, and in particular to a wind-resistant hook wheel assembly for retractable gates. Background Technology

[0002] Electric retractable gates are a type of automated gate widely used in residential areas, factories, schools, and parking lots. They feature flexible opening and closing, as well as safety and intelligence. Retractable gates typically use wind-resistant hooks that slide along an I-beam track. Existing wind-resistant hooks have grooves inside, with the rotating shaft directly inserted into the grooves via bearings so that the bearings can slide within the grooves. The rotating shafts also have pulleys that cooperate with the track on the ground. The rollers of the two rotating shafts slide along the track to increase the stability of the retractable gate. However, uneven ground can cause the track and rollers to slide up and down. As the rollers roll along the track, they can easily cause the outer ring of the bearing to rotate within the groove, resulting in wear and noise, which in turn affects the retractable gate's extension and retraction. Therefore, a new type of wind-resistant hook structure for retractable gates is needed to solve these problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a rectangular mounting block and a rectangular receiving cavity for a wind-resistant hook wheel assembly for a telescopic gate. The rectangular mounting block can be limited in position, and the bearing on the rotating shaft is installed inside the rectangular mounting block. The connection between the bearing and the rectangular mounting block is tighter, so as to prevent the outer ring of the bearing from wearing and causing noise as the rotating shaft rotates. The rectangular mounting block can move up and down along the rectangular receiving cavity. If the ground is uneven, the annular protrusion can drive the rectangular mounting block to move up and down through the rotating shaft, and make the annular protrusion slide smoothly on the surface of the track, ensuring that the telescopic gate can move up and down normally.

[0004] A wind-resistant hook wheel assembly for a telescopic gate includes a mounting box, a rectangular mounting block, and a rotating shaft mounted on the gate body. The mounting box has a rectangular receiving cavity, and the rectangular mounting block is housed within the rectangular receiving cavity and can move up and down along the rectangular receiving cavity. The rotating shaft is slidably connected to the bottom surface of the mounting box. One end of the rotating shaft extends into the receiving cavity and is rotatably connected to the rectangular mounting block through a bearing. The other end of the rotating shaft extends out of the receiving cavity and is provided with two annular protrusions. A groove is formed between the two annular protrusions to cooperate with the rolling of the track.

[0005] Preferably, the mounting box has outwardly extending mounting pieces on its left and right sides, and the mounting pieces have multiple mounting through holes.

[0006] Preferably, the accommodating cavity includes two cavities, the bottom surface of the accommodating cavity is provided with an opening, and the rotating shaft extends into the accommodating cavity through the opening.

[0007] Preferably, the rectangular mounting block is provided with a through groove, and one end of the rotating shaft is rotatably connected to the through groove of the rectangular mounting block through a bearing.

[0008] Preferably, the portion of the rotating shaft located outside the mounting box is provided with a columnar protrusion, and two annular protrusions are arranged from top to bottom, with the outer diameter of the annular protrusion closer to the columnar protrusion being larger than the outer diameter of the other annular protrusion.

[0009] Preferably, the bottom surface of the accommodating cavity is provided with a plurality of inserts adjacent to the opening, the bottom surface of the rectangular mounting block is provided with a plurality of sliding grooves, the plurality of inserts are slidably connected to the plurality of sliding grooves, and the plurality of sliding grooves are connected to the plurality of inserts by telescopic springs, and the plurality of telescopic springs are fitted onto the plurality of inserts.

[0010] The beneficial effects of this utility model are as follows: The wind-resistant hook wheel assembly of the telescopic gate works together with the mounting box, the rectangular mounting block and the rotating shaft, so that the rectangular mounting block can be limited by the rectangular receiving cavity. The bearing on the rotating shaft is installed inside the rectangular mounting block, and the connection between the bearing and the rectangular mounting block is tighter, so as to prevent the outer ring of the bearing from wearing and making noise as the rotating shaft rotates. The rectangular mounting block can move up and down along the rectangular receiving cavity. If the ground is uneven, the annular protrusion can drive the rectangular mounting block to move up and down through the rotating shaft, and make the annular protrusion slide smoothly to adapt to the surface of the track, so as to ensure that the telescopic gate can move normally.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0017] like Figures 1 to 4As shown, a wind-resistant hook wheel assembly for a telescopic gate includes a mounting box 1, a rectangular mounting block 2, and a rotating shaft 3 mounted on the gate body. The mounting box 1 has a rectangular receiving cavity 4. The rectangular mounting block 2 is housed in the rectangular receiving cavity 4 and can move up and down along the rectangular receiving cavity 4. The rotating shaft 3 is slidably connected to the bottom surface of the mounting box 1. One end of the rotating shaft 3 extends into the receiving cavity and is rotatably connected to the rectangular mounting block 2 through a bearing. The other end of the rotating shaft 3 extends out of the receiving cavity and is provided with two annular protrusions 5. A groove 6 is formed between the two annular protrusions 5 to cooperate with the rolling of the track.

[0018] The working principle of the wind-resistant hook wheel assembly for telescopic gates described in this utility model is achieved through the cooperation of the mutual mounting box 1, the rectangular mounting block 2, and the rotating shaft 3. Figures 1 to 4 As shown, the groove 6 formed between the two annular protrusions 5 on the rotating shaft 3 is connected to the top of the I-shaped track (not shown in the figure). The annular protrusions 5 of the two rotating shafts 3 are locked on the track, and the track is positioned between the annular protrusions 5 of the two rotating shafts 3. When the windproof hook moves with the door, the annular protrusions 5 on the rotating shaft 3 roll along the track. The rectangular mounting block 2 and the rectangular receiving cavity 4 cooperate to limit the rectangular mounting block 2. The bearing on the rotating shaft 3 is installed inside the rectangular mounting block 2, and the connection between the bearing and the rectangular mounting block 2 is tighter to prevent the outer ring of the bearing from rotating with the rotating shaft 3. This design avoids wear and noise, and the rectangular mounting block 2 can move up and down along the rectangular receiving cavity 4. If the ground is uneven, the annular protrusion 5 can drive the rectangular mounting block 2 to move up and down through the rotating shaft 3, and make the annular protrusion 5 slide smoothly on the surface of the track. Compared with the traditional windproof hook, the windproof hook wheel assembly of this telescopic gate avoids the outer ring of the bearing from rotating and causing wear and noise by installing the bearing through the rectangular mounting block 2, thus achieving a silent effect. Even if the annular protrusion 5 of the rotating shaft 3 moves on the track surface on uneven ground, it can ensure that the telescopic gate can move normally.

[0019] Specifically, the mounting box 1 has outwardly extending mounting pieces 7 on its left and right sides, and each mounting piece 7 has multiple mounting through holes. The accommodating cavity includes two cavities, each with an opening 8 on its bottom surface. The rotating shaft 3 extends into the accommodating cavity through the opening 8. The rectangular mounting block 2 has a through groove 9, and one end of the rotating shaft 3 is rotatably connected to the through groove 9 of the rectangular mounting block 2 via a bearing. Figures 1 to 4 As shown, a mounting slot can be installed in the through groove 9 to fix the bearing, so that the bearing is installed more tightly with the rectangular mounting block 2, so as to prevent the outer ring of the bearing from rotating with the shaft 3. The operator can connect the mounting box 1 to the door body by screws and mounting through holes on the mounting plate 7. A ball bearing can be installed in the through groove 9 in the rectangular mounting block 2 to rotate and connect with the shaft 3. The shaft 3 rotates in the rectangular mounting block 2, and the shaft 3 can drive the rectangular mounting block 2 to move up and down in the accommodating cavity.

[0020] Furthermore, the portion of the rotating shaft 3 located outside the mounting box 1 is provided with a columnar protrusion 10, and two annular protrusions 5 are arranged from top to bottom, with the outer diameter of the annular protrusion 5 closer to the columnar protrusion 10 being larger than the outer diameter of the other annular protrusion 5. Even further, the bottom surface of the accommodating cavity is provided with multiple insertion posts 11 adjacent to the opening 8, and the bottom surface of the rectangular mounting block 2 is provided with multiple sliding grooves 12. The multiple insertion posts 11 are slidably connected to the multiple sliding grooves 12, and the multiple sliding grooves 12 are connected to the multiple insertion posts 11 via telescopic springs 13, with the multiple telescopic springs 13 correspondingly fitted onto the multiple insertion posts 11. Figures 1 to 4 As shown, when the rectangular mounting block 2 moves upward in the accommodating cavity, the rectangular mounting block 2 stretches the telescopic spring 13, and the insert 11 extends out from the slide groove 12 of the rectangular mounting block 2, which serves to guide the rectangular mounting block 2. When the rectangular mounting block 2 tightens the telescopic spring 13 and the columnar protrusion 10 abuts against the bottom surface of the mounting box 1, the movement stroke of the rectangular mounting block 2 and the annular protrusion 5 can be limited to prevent the annular protrusion 5 from moving too far and easily falling off the track. In addition, the rectangular mounting block 2 is subjected to the action of the telescopic spring 13, which can make the annular protrusion 5 reset faster and the annular protrusion 5 fit more tightly with the track.

[0021] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
