[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: A building automation DDC controller, such as Figures 1-4 As shown, it includes a controller body 1 and four annular fastening frames 14 symmetrically distributed below the controller body 1. A positioning groove 2 for fastening is provided on the lower end surface of the controller body 1. The number of the positioning grooves 2 is the same as that of the annular fastening frames 14. An annular plug-in groove 13 is provided through the middle of the annular fastening frame 14. A positioning bolt 3 is inserted in the middle of the annular plug-in groove 13. The positioning bolt 3 extends to the inside of the positioning groove 2, and the positioning bolt 3 is threadedly connected to the inner wall of the positioning groove 2. Mounting pads 8 are protruding on both sides of the opposite sides of the annular fastening frame 14, and fastening bolts 9 for positioning and fastening are provided on the mounting pad 8.

[0026] When installing the device, adjust the distance that the annular fastening frame 14 extends out of the outside of the controller body 1 according to the size of the space where it is used, and then rotate the positioning bolt 3 to fasten it with the positioning groove 2. Based on the simultaneous insertion of the positioning bolt 3 and the annular plug-in groove 13, the position of the annular fastening frame 14 is limited, the distance extended by the annular fastening frame 14 is fixed, and then the fastening bolt 9 is used to fix the mounting pad 8 in the installation position. By setting the distance of the annular fastening frame 14 to be adjustable and the positioning of the positioning bolt 3 to fix the adjusted position in time, and setting the mounting pad 8 to protrude from the surface of the annular fastening frame 14, it is ensured that the horizontal planes at both ends of the annular fastening frame 14 are stable after it is limited and fixed, so that the device can be stably and accurately installed in different spatial environments.

[0027] like Figures 1-4As shown, a positioning ring 4 is inserted into the upper half of the positioning bolt 3 , and a fastening nut 5 is provided above the positioning ring 4 , and the fastening nut 5 is threadedly connected to the outer side of the positioning ring 4 .

[0028] The lower end surface of the positioning ring 4 is provided with a plug-in rod 6 for limiting, and the plug-in rod 6 is plugged with a positioning rod 7. There are several positioning rods 7, and the positioning rods 7 are evenly distributed on the upper end surface of the annular fastening frame 14.

[0029] The plug-in rod 6 and the positioning rod 7 are cross-connected, and the positioning ring 4 and the fastening nut 5 are both located above the annular fastening frame 14 .

[0030] Based on the threaded connection between the fastening nut 5 and the positioning bolt 3, and the threaded connection between the positioning bolt 3 and the positioning groove 2, when the fastening nut 5 is continuously rotated on the outside of the positioning bolt 3, the positioning ring 4 is squeezed and moved downward at the same time. At this time, based on the cross-connection of the plug-in rod 6 and the positioning rod 7, the positioning ring 4 is limited above the annular fastening frame 14, and the fastening nut 5 continues to be rotated. Under the limitation of the positioning ring 4, the positioning bolt 3 is driven to rotate inside the positioning groove 2, so that the fastening nut 5 and the positioning bolt 3, the positioning ring 4 and the annular fastening frame 14, and the positioning bolt 3 and the positioning groove 2 are mutually limited and supported, forming an effect of squeezing and limiting the annular fastening frame 14, and under the connection between the positioning rod 7 and the plug-in rod 6, the annular fastening frame 14 is effectively prevented from sliding and offsetting during use and tightening.

[0031] Example 2: A building automation DDC controller, such as Figures 1-4 As shown, the mounting pad 8 and the upper end of the positioning bolt 3 are located at the same horizontal plane, and the mounting pads 8 on both sides are plugged into the fastening bolts 9 at the same time, and the fastening bolts 9 are plugged into the annular fastening frame 14 at the same time.

[0032] By arranging the upper end surface of the mounting pad 8 and the upper end surface of the positioning bolt 3 after rotation and tightening on the same horizontal plane, the mounting pad 8 and the positioning bolt 3 are always in the same horizontal position when the device is tightened for use, ensuring the stability of the horizontal plane of the annular fastening frame 14 itself and effectively preventing it from breaking or bending.

[0033] like Figures 1-4 As shown, a rotating cap 10 is installed on the end surface of the fastening bolt 9 away from the mounting pad 8, and a fastening edge 12 for rotational fastening is provided on the outer side of the rotating cap 10.

[0034] A fastening groove 11 is provided in the middle of the upper end of the rotating cap 10 . The fastening groove 11 and the fastening edge 12 are both used for rotating and fastening the fastening bolt 9 .

[0035] Based on the fastening groove 11, a cross-shaped rotation support is provided from the middle of the rotating cap 10, and based on the fastening edge 12, a hexagonal rotation support is provided from the outside of the rotating cap 10. The fastening bolt 9 can be rotated in different directions, so that a reasonable fastening method can be performed according to the installation space, which has improved the diverse selectivity when the device is installed and used.

[0036] Working principle: When installing the device, first loosen the positioning of the annular fastening frame 14, then adjust the distance that the annular fastening frame 14 extends out of the outside of the controller body 1 to meet the current installation space. Based on the threaded connection between the fastening nut 5 and the positioning bolt 3, and the threaded connection between the positioning bolt 3 and the positioning groove 2, when the fastening nut 5 is continuously rotated on the outside of the positioning bolt 3, the positioning ring 4 is squeezed and moved downward at the same time. At this time, based on the cross-connection of the plug rod 6 and the positioning rod 7, the positioning ring 4 is limited above the annular fastening frame 14, and the fastening nut 5 is continued to be rotated. Under the limitation of the positioning ring 4, the positioning bolt 3 is driven to rotate inside the positioning groove 2, forming an effect of squeezing and limiting the annular fastening frame 14, and the mounting pad 8 is set to protrude from the surface of the annular fastening frame 14 to ensure that after it is limited and fixed, the horizontal planes at both ends of the annular fastening frame 14 are stable. Based on the fastening groove 11, a cross-shaped rotation support is performed from the middle of the rotating cap 10, and based on the fastening edge 12, a hexagonal rotation support is performed from the outside of the rotating cap 10, which can rotate the fastening bolt 9 in different directions, so that the device can be stably and accurately installed in different spatial environments.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
