[0048] The above functions and working principles are all prior art, which are clearly known to those skilled in the art and will not be elaborated here.

[0049] The fastening assembly 200 is arranged on the hanging plate 102, and includes an expansion bolt 201, a magnetic plate 202, a connecting piece 203, a pre-tightening piece 204, a fastener 205 and a limit piece 206. An adjustment slot S is opened on the hanging plate 102, and the expansion bolt 201 slides in the adjustment slot S. The magnetic plate 202 is arranged at the end of the expansion bolt 201, and the connecting piece 203 is fixed between the expansion bolt 201 and the magnetic plate 202. Installation slots P are opened on both sides of the hanging plate 102, and the pre-tightening piece 204 is arranged in the installation slot P. The fastener 205 is arranged on the magnetic plate 202, and the limit piece 206 is arranged at the top and bottom of the pre-tightening piece 204.

[0050] Two expansion bolts 201 are provided. Compared with the prior art method of fixing with at least four expansion bolts 201, the two expansion bolts 201 are more convenient to operate, and they can move on the adjustment slot S to adjust the installation position of the hanging plate 102, thereby adjusting the position of the controller host 101 to prevent the staff from performing other operations on the area near the hanging plate 102 after the installation is completed, and the controller host 101 hinders the staff's operation.

[0051] The magnetic plate 202 is installed on the expansion bolt 201 through the connecting piece 203. The pre-tightening piece 204 can be used to pre-tighten and limit the hanging plate 102 when installing it, so that it can be firmly fixed in the preset position. When the controller host 101 is installed on the hanging plate 102, the fastener 205 and the limiting piece 206 can be used to fix the hanging plate 102 and the controller host 101, making its installation more convenient and stable.

[0052] Example 2

[0053] Reference Figures 1 to 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0054] Specifically, the connecting member 203 includes a first magnet 203a and a second magnet 203b. The first magnet 203a is fixed to the end of the expansion bolt 201. A groove K is provided on the inner side of the magnetic attraction plate 202. The second magnet 203b is fixed in the groove K and cooperates with the first magnet 203a.

[0055] The magnetic plate 202 can be installed through the first magnet 203a and the second magnet 203b. It only needs to be placed on the end of the expansion bolt 201 to fix it through the mutual attraction of the two magnets. The setting of the groove K can prevent the magnetic plate 202 from being misplaced during installation and use, while improving its installation convenience.

[0056] The preload member 204 includes a movable plate 204a, an inclined plate 204b, a mounting plate 204c and a trigger rod 204d. The movable plate 204a slides in the mounting groove P and cooperates with the expansion bolt 201. The inclined plate 204b is fixed on one side of the movable plate 204a. The mounting plate 204c is fixed on the outside of the mounting groove P. The trigger rod 204d slides on the mounting plate 204c and cooperates with the inclined plate 204b.

[0057] The side of the movable plate 204a close to the expansion bolt 201 is made of rubber or other materials with large friction. In the initial state, the movable plate 204a is in contact with the expansion bolt 201, and the hanging plate 102 is pre-tightened and limited by the friction between the movable plate 204a and the expansion bolt 201, so that the staff can fine-tighten the position of the hanging plate 102. At the same time, the hanging plate 102 will not move accidentally due to its own gravity. The top and bottom of the inclined plate 204b are both provided with inclined surfaces, and the trigger rod 204d is L-shaped. When the two trigger rods 204d are close to each other, the end of the trigger rod 204d moves on the inclined surface, thereby driving the inclined plate 204b and the movable plate 204a to move away from the expansion bolt 201, so that the movable plate 204a is separated from the expansion bolt 201. At this time, the staff can adjust the position of the hanging plate 102 more conveniently.

[0058] The preload member 204 also includes a first spring 204e and a fixed block 204f. A slide groove V is provided on the mounting plate 204c. The trigger rod 204d slides in the slide groove V. Both ends of the first spring 204e are respectively fixed to the trigger rod 204d and the inner wall of the slide groove V. The fixed block 204f is fixed to one end of the trigger rod 204d and is located on the outer side of the mounting plate 204c.

[0059] The fixing block 204f is used to limit the trigger rod 204d to prevent it from deflecting during the up and down movement. The first spring 204e applies an outward thrust to the trigger rod 204d to facilitate its reset.

[0060] The preload member 204 also includes a limit block 204g, a second spring 204h and a third spring 204i. The limit block 204g is fixed to the top and bottom of the inner wall of the mounting groove P. The two ends of the second spring 204h are respectively fixed to the limit block 204g and the movable plate 204a. The two ends of the third spring 204i are respectively fixed to the inclined plate 204b and the mounting plate 204c.

[0061] The limit block 204g is used to limit the movable plate 204a to prevent it from detaching from the installation groove P. The second spring 204h and the third spring 204i jointly apply a thrust to the movable plate 204a in the direction of the expansion bolt 201, so that the movable plate 204a can apply greater pressure to the expansion bolt 201, thereby improving the stability of the hanging plate 102 in the initial state.

[0062] The fastener 205 includes an insertion rod 205a and a fixing plate 205b. A plug hole M is provided on the hanging plate 102. The insertion rod 205a slides on the magnetic plate 202 and cooperates with the plug hole M. The fixing plate 205b is fixed to one end of the insertion rod 205a.

[0063] There are multiple groups of sockets M, which are evenly distributed on the hanging plate 102. When installing the monitoring controller, the hanging plate 102 and the magnetic plate 202 can be fixed by pushing the four plug rods 205a into the sockets M through the monitoring controller to avoid accidental displacement or falling of the hanging plate 102 during use. The fixing plate 205b can prevent the plug rods 205a from detaching from the magnetic plate 202.

[0064] The fastener 205 further includes a fourth spring 205c, two ends of which are respectively fixed to the magnetic attraction plate 202 and the fixing plate 205b.

[0065] The fourth spring 205c applies thrust to the fixed plate 205b and the insertion rod 205a. When the monitoring controller is separated from the magnetic plate 202, the fourth spring 205c drives the insertion rod 205a to disengage from the socket M, thereby automatically releasing the limiting effect on the hanging plate 102 without additional operation.

[0066] An inspection slot L is provided on the inner side of the magnetic attraction plate 202, and the insertion rod 205a is located in the inspection slot L. A fitting slot H is provided on the outer side of the magnetic attraction plate 202, and the fitting slot H cooperates with the fixing plate 205b.

[0067] The inspection slot L facilitates manual operation by the staff when the insertion rod 205a becomes stuck or displaced, or the socket M is damaged. The size of the fitting slot H is the same as the fixed disk 205b. When the monitoring controller is in contact with the magnetic plate 202, the fixed disk 205b will be located in the fitting slot H, so that the monitoring controller and the magnetic plate 202 can be fully in contact, and at the same time the insertion rod 205a can be more firmly inserted into the socket M.

[0068] The limiting member 206 includes a connecting rod 206a and an insert plate 206b. Connecting grooves T are provided at the top and bottom of the installation groove P. The connecting rod 206a is fixed to the top and bottom of the movable plate 204a and slides in the connecting groove T. The insert plate 206b is fixed to one side of the connecting rod 206a. Limiting holes U cooperating with the hook 103 are provided on both sides.

[0069] The connecting rod 206a is L-shaped, and it slides in the connecting groove T following the movable plate 204a. The plug plate 206b is also L-shaped. When the monitoring controller is installed on the hanging plate 102, the two sets of hooks 103 and the receiving hooks 104 are correspondingly buckled. At the same time, the two hooks 103 first push the plug plate 206b and the connecting rod 206a outward. When the hooks 103 and the receiving hooks 104 are installed in place, the plug plate 206b is correspondingly plugged into the limiting hole U, which can further limit and fix the hook 103, thereby improving the convenience of its installation. In this process, since the monitoring controller pushes the plug rod 205a to be correspondingly plugged into the socket M, the position of the hanging plate 102 is fixed, and the separation of the movable plate 204a and the expansion bolt 201 will not cause the hanging plate 102 to move.

[0070] When the installation is completed and the position of the hanging plate 102 needs to be moved, the staff first removes the monitoring controller, and then manually pushes the trigger rods 204d on both sides inward, and drives the inclined plate 204b and the movable plate 204a to move away from the expansion bolt 201 through the trigger rods 204d, so that the movable plate 204a is separated from the expansion bolt 201. At this time, the staff can adjust the position of the hanging plate 102 more conveniently.

[0071] A rectangular groove Y is formed on the hanging plate 102 , and the inserting plate 206 b slides in the rectangular groove Y.

[0072] The rectangular groove Y facilitates the left-right movement of the plug board 206b, thereby improving its convenience in use.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
