[0029] Please refer to Figure 1-6, the present utility model provides a technical solution:
[0030] A padlock device for an electric operating mechanism, comprising a base housing 3 and a positioning post 31. A padlock assembly 1 is movably installed at the upper end of the base housing 3, and a handle 2 is movably installed at the lower end of the padlock assembly 1. The outer surface of the handle 2 is set as the handle outer wall 21, and an outer wall boss 22 is fixedly connected to the outer surface of the handle outer wall 21. The end face of the handle 2 is set as the handle opening limit surface 23, and a second padlock feature boss 127 is fixedly connected to the outer surface of the handle outer wall 21;
[0031] The padlock assembly 1 includes a manual dial block 112 and a first padlock feature boss 126. A positioning groove 114 penetrating up and down is opened in the middle of the front end of the manual dial block 112. The inner wall surface of the positioning groove 114 is set as a positioning groove chamfer 111. A third deformation groove 115 penetrating up and down, a second deformation groove 116 penetrating up and down, and a first deformation groove 117 penetrating up and down are opened in the left part of the front end of the manual dial block 112. A padlock hole 113 penetrating up and down is opened in the right part of the front end of the manual dial block 112.
[0032] In this embodiment, the third deformation groove 115 is located on the left side of the second deformation groove 116, the first deformation groove 117 is located on the right side of the second deformation groove 116, and the third deformation groove 115, the second deformation groove 116, and the first deformation groove 117 are all communicated; a positioning boss 121 and a positioning buckle 122 are fixedly connected to the left part of the front end of the first padlock feature boss 126. The positioning boss 121 is located on the right side of the positioning buckle 122. A first limit boss 123 is fixedly connected to the upper left part of the first padlock feature boss 126, a second limit boss 124 is fixedly connected to the middle of the upper end of the first padlock feature boss 126, and a third limit boss 125 is fixedly connected to the upper right part of the first padlock feature boss 126; the positioning boss 121 and the positioning buckle 122 are both clamped in the positioning groove 114; the positioning post 31 is clamped in the third deformation groove 115 or the second deformation groove 116 or the first deformation groove 117; the outer wall boss 22 is in contact with the first padlock feature boss 126, and the rear end of the handle 2 is movably connected to the inner wall surface of the base housing 3 through a bearing.
[0033] It should be noted that the present utility model is a padlock device for an electric operating mechanism. During use, the padlock assembly 1 and the first padlock feature boss 126 are assembled. The positioning boss 121 and the positioning buckle 122 on the padlock assembly 1 are inserted into the positioning groove 114 on the first padlock feature boss 126. And the positioning groove 114 on the first padlock feature boss 126 has a positioning groove chamfer 111 for easy installation. The positioning buckle 122 is an inverted buckle structure. After being inserted, the positioning buckle 122 will be fixed in the positioning groove 114 and cannot be taken out;
[0034] Such as Figure 4As shown, this position is the automatic position. Under this position, electric operation and manual operation can be carried out. Since there is no contact between the padlock assembly 1 and the handle 2, the handle 2 can rotate freely for opening and closing.
[0035] As Figure 5 shown, this position is the manual position. Under this position, manual operation can be carried out while electric operation cannot (Reason: The microswitch controlling electric operation on the PCB in this state will be disconnected). Since there is no contact between the padlock assembly 1 and the handle 2, the handle 2 can rotate freely for opening and closing. But as Figure 5 this is the closing position at this time. If the manual toggle block 112 is continuously braked to move to the right, the first padlock feature boss 126 of the padlock assembly 1 will collide with the outer wall 21 of the handle 2, and the second padlock feature boss 127 of the padlock assembly 1 will collide with the outer wall boss 22 of the handle 2. With double-point limiting, the padlock assembly 1 cannot move to the padlock position, achieving the purpose of preventing padlocking in the closing position.
[0036] As Figure 6 shown, this position is the padlock position. At this time, the third deformation groove 115 of the padlock assembly 1 is stuck in the positioning post 31 of the base housing 3, and the first padlock feature boss 126 of the padlock assembly 1 is exactly in contact with the handle opening limit surface 23 of the handle 2. A φ4mm lock is inserted into the padlock hole 113 of the padlock assembly 1, so that the padlock assembly 1 cannot be moved. When manual closing is carried out, since the first padlock feature boss 126 of the padlock assembly 1 is already in contact with the handle opening limit surface 23 of the handle 2, manual closing cannot be carried out, achieving the effect of preventing manual closing in the padlock position.
[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
