Description

Technical Field

[0001] This utility model relates to the field of door opener technology, and in particular to an automatic door opener speed control mechanism. Background Technology

[0002] A door opener is a actuator used to automatically open or close a door. With the advancement of technology and the improvement of living standards, it is becoming increasingly widely used; its role is particularly important in situations where the door is heavy.

[0003] Currently, traditional automatic door openers are usually installed on the door. When they sense someone passing by, the door opener will automatically open the door. However, the door opener opens the door very quickly, which may cause people standing behind or in front of the door to be unable to avoid it in time, resulting in injury. Therefore, it is very inconvenient and unsafe to use.

[0004] Therefore, it is necessary to provide an automatic door opener speed control mechanism that allows for easy adjustment of the slow opening during door opening and closing to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic door opener speed adjustment mechanism.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A schematic diagram of a preferred embodiment of an automatic door opener speed control mechanism provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the structure. Figure 3 for Figure 1 The diagram shows the structure of the speed-changing mechanism. An automatic door opener speed-regulating mechanism includes a protective shell 1. Connecting blocks 2 are welded and fixed to each of the four corners of the protective shell 1. A through hole is provided at the bottom of the protective shell 1. A positioning plate 3 is bolted to the bottom of the protective shell 1. A sensor 4 is bolted to the front end of the positioning plate 3. A fixing plate 5 is provided at the bottom of the protective shell 1. A speed-changing mechanism 6 is provided on one side of the top of the protective shell 1. The speed-changing mechanism 6 facilitates adjustment for slow opening during door opening and closing. A support frame 7 is bolted to one side of the top of the protective shell 1. An electric telescopic rod 8 is bolted to the bottom of the support frame 7.

[0020] In the specific implementation process, such as Figure 1 Figure 2 and Figure 3 As shown, the speed change mechanism 6 includes a drive motor 61. The bottom of the drive motor 61 is bolted to the protective shell 1. The output end of the drive motor 61 passes through the inner cavity of the protective shell 1 and is keyed to a first bevel gear 62. A second bevel gear 63 is meshed with one side of the first bevel gear 62. A lead screw 64 is welded to one side of the second bevel gear 63. A threaded sleeve 65 is threaded to the surface of the lead screw 64. A support rod 66 is welded to the bottom of the threaded sleeve 65. The bottom of the support rod 66 passes through the inner cavity of the through hole and is connected to an adjusting rod 67 through a rotating shaft. The bottom of the adjusting rod 67 is connected to the fixing plate 5 through a bearing. A third bevel gear 68 is keyed to one side of the lead screw 64. A fourth bevel gear 69 is meshed with the top of the third bevel gear 68. The top of the fourth bevel gear 69 is bolted to an electric telescopic rod 8.

[0021] When opening and closing the door slowly, the drive motor 61 is first turned on, and the output end of the drive motor 61 drives the first bevel gear 62 to rotate. At the same time as the first bevel gear 62 rotates, it meshes with the second bevel gear 63 to rotate. At the same time as the second bevel gear 63 rotates, it drives the lead screw 64 to rotate. At the same time as the lead screw 64 rotates, it drives the lead sleeve 65 to move. At the same time as the lead sleeve 65 moves, it drives the support rod 66 to move in the inner cavity of the through hole. At the same time as the support rod 66 moves, it drives the adjusting rod 67 to move and adjust. At the same time as the adjusting rod 67 moves, it drives the fixing plate 5 to move. At the same time as the fixing plate 5 moves, it drives the door to open, thus effectively achieving the effect of slowly opening and closing the door.

[0022] Subsequently, when the user needs to adjust the opening speed, the screw 64 rotates while driving the third bevel gear 68 to rotate, which in turn opens the electric telescopic rod 8 and drives the fourth bevel gear 69 to move downward. As the fourth bevel gear 69 descends, it engages with the third bevel gear 68. At this time, the third bevel gear 68 rotates while engaging the fourth bevel gear 69, thus effectively adjusting the opening speed.

[0023] refer to Figure 3 As shown, positioning rods 9 are welded and fixed on opposite sides of the second bevel gear 63 and the third bevel gear 68, and the opposite sides of the two positioning rods 9 are connected to the protective shell 1 through bearings.

[0024] The connection between the positioning rod 9 and the protective shell 1 serves to limit and support the second bevel gear 63 and the third bevel gear 68.

[0025] refer to Figure 3 As shown, the bottom of the drive motor 61 is keyed to a limit ring 10, and the bottom of the limit ring 10 is keyed to the protective shell 1.

[0026] The connection between the limiting ring 10 and the protective shell 1 effectively limits the movement of the drive motor 61.

[0027] refer to Figure 2 As shown, a reinforcing block 11 is welded and fixed to the bottom of one side of the support frame 7, and the bottom of the reinforcing block 11 is bolted to the protective shell 1.

[0028] The connection between the reinforcing block 11 and the protective shell 1 effectively reinforces and fixes the support frame 7.

[0029] refer to Figure 2 and Figure 3 As shown, positioning blocks 12 are welded and fixed on both sides of the fixing plate 5. Nuts 13 are threadedly connected to the inner cavity of the positioning blocks 12, and the surface of the nuts 13 is connected to the door thread.

[0030] The connection between nut 13 and the door panel serves to position the fixing plate 5.

[0031] The working principle of the automatic door opener speed control mechanism provided by this utility model is as follows:

[0032] In use, the protective shell 1 is first fixed to the door frame with bolts via the connecting block 2. Then, the fixing plate 5 is fixed to the door panel with bolts. When someone needs to open the door, the sensor 4 will first detect the person at the doorway, and then automatically turn on the drive motor 61. The output of the drive motor 61 drives the first bevel gear 62 to rotate. Simultaneously, the first bevel gear 62 meshes with the second bevel gear 63, causing it to rotate. Simultaneously, the second bevel gear 63 rotates, driving the lead screw 64 to rotate. Simultaneously, the lead screw 64 rotates, causing the threaded sleeve 65 to move. Simultaneously, the threaded sleeve 65 moves, causing the support rod 66 to move within the through hole. While moving, the adjusting rod 67 moves, which in turn moves the fixing plate 5. Simultaneously, the fixing plate 5 moves, causing the door to open. This effectively allows for a slow opening and closing of the door. Finally, when the user needs to adjust the opening speed, the lead screw 64 rotates, causing the third bevel gear 68 to rotate. This opens the electric telescopic rod 8, causing the fourth bevel gear 69 to move downwards. As the fourth bevel gear 69 descends, it engages with the third bevel gear 68. At this point, the rotation of the third bevel gear 68 simultaneously engages with the fourth bevel gear 69, effectively adjusting the opening speed.

[0033] The above description is merely an embodiment of this utility model and does 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.
