Two positioning plates are symmetrically arranged within each mounting slot, and the two positioning plates abut against the outer walls of the fastening bolts at both ends of the mounting slot. A winding drum is rotatably inserted into the mounting slot, and a control rod is movably inserted into the winding drum. The control rod controls the rotation of the winding drum, and its front end extends out of the winding drum and abuts against the back of the box body. The outer walls of the positioning plates are connected to the winding drum by steel cables.

[0008] Further defining the above technical solution, the front side of the fixing plate is fixedly provided with two bottom plates and two side plates, the bottom surface of the box body is attached to the top surface of the bottom plates, and the side wall of the box body is attached to the side wall of the side plates.

[0009] Further defining the above technical solution, a plurality of limiting rods are fixedly provided on the top surface of the base plate, and the plurality of limiting rods are movably inserted into the bottom surface of the box. Positioning bolts are threaded into the side wall of the side plate, and the ends of the positioning bolts pass through the side plate and are inserted into the side wall of the box.

[0010] Further defining the above technical solution, the positioning plate is arc-shaped, and a rubber pad is fixedly provided on the inner side of the positioning plate.

[0011] To further define the above technical solution, two first springs are symmetrically arranged on the outer side of the positioning plate, and the ends of the two first springs away from the positioning plate are fixedly connected to the inner wall of the mounting groove.

[0012] As a further limitation of the above technical solution, the outer wall of the winding drum is provided with an annular groove, and the inner wall of the winding drum is provided with a spiral groove.

[0013] Further defining the above technical solution, the control rod includes a movable rod and a rubber disc.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0024] Example 1: This example provides a suspended power metering box, such as... Figure 1 As shown, this invention solves the problem that when an electricity metering box is fixed to the wall with bolts, a single bolt is prone to automatic rotation when subjected to vibration, which can easily lead to loosening of the bolt and affect the installation stability of the electricity metering box. The invention includes a fixing plate 1 and a box body 2 on the front side of the fixing plate 1. The front side of the fixing plate 1 has two mounting grooves 3, and fastening bolts 4 are threaded into both ends of the two mounting grooves 3. Two positioning plates 5 are symmetrically arranged in the mounting grooves 3, and the two positioning plates 5 abut against the outer walls of the fastening bolts 4 at both ends of the mounting grooves 3. A winding drum 6 is rotatably inserted into the mounting grooves 3, and a control rod 7 is movably inserted into the winding drum 6. The control rod 7 is used to control the rotation of the winding drum 6. The front end of the control rod 7 extends out of the winding drum 6 and abuts against the back of the box body 2. The outer wall of the positioning plate 5 is connected to the winding drum 6 by a steel cable 8.

[0025] First, the fixing plate 1 is installed on the wall using the fastening bolts 4, and then the housing 2 is installed on the fixing plate 1. At this time, the housing 2 pushes the control rod 7 to insert into the winding drum 6, and causes the winding drum 6 to rotate to release the steel cable 8. At this time, the positioning plate 5 loses tension and moves towards the fastening bolt 4 and comes into contact with the fastening bolt 4, thereby locking the fastening bolt 4 to reduce the possibility of the fastening bolt 4 automatically rotating and loosening. Therefore, the device is more stable when suspended.

[0026] Combination Figure 2In the embodiments of this utility model, the positioning plate 5 is arc-shaped, and a rubber pad is fixedly provided on the inner side of the positioning plate 5. When the positioning plate 5 is in contact with the fastening bolt 4, the rubber pad can increase the friction between the positioning plate 5 and the fastening bolt 4, thereby reducing the possibility of the fastening bolt 4 loosening.

[0027] Combination Figure 1 , Figure 2 In this embodiment of the utility model, two first springs 51 are symmetrically arranged on the outer side of the positioning plate 5. The ends of the two first springs 51 away from the positioning plate 5 are fixedly connected to the inner wall of the mounting groove 3. When the steel cable 8 is released, the positioning plate 5 is pushed to move by the first springs 51, thereby causing the positioning plate 5 to abut against the fastening bolt 4, so as to lock the fastening bolt 4. When the steel cable 8 is wound up, the positioning plate 5 is pulled to move and separate from the fastening bolt 4 by the steel cable 8, and the first springs 51 are compressed and deformed.

[0028] Example 2: Reference Figure 2 Two base plates 11 and two side plates 12 are fixedly installed on the front side of the fixing plate 1. The bottom surface of the box 2 is attached to the top surface of the base plate 11, and the side wall of the box 2 is attached to the side wall of the side plate 12. The two side plates 12 and the two base plates 11 cooperate to facilitate the support and limitation of the box 2, thereby facilitating the installation of the box 2 on the fixing plate 1.

[0029] Several limiting rods 13 are fixedly installed on the top surface of the base plate 11. The limiting rods 13 are movably inserted into the bottom surface of the box 2. The side wall of the side plate 12 is threaded with positioning bolts 14. The end of the positioning bolt 14 passes through the side plate 12 and is inserted into the side wall of the box 2. The insertion of the limiting rods 13 into the bottom surface of the box 2 facilitates the limiting of the bottom surface of the box 2. The positioning bolts 14 facilitate the limiting of the side wall of the box 2. This makes it easy to fix the box 2 between the base plate 11 and the side plate 12 and increases the stability of the connection between the box 2 and the fixed plate 1.

[0030] Example 3: Reference Figure 2 , Figure 3 The outer wall of the winding drum 6 is provided with an annular groove 61, and the inside of the winding drum 6 is provided with a spiral groove 62. The annular groove 61 facilitates the storage of the steel cable 8.

[0031] The control lever 7 includes a movable lever 71 and a rubber disc 72. One end of the movable lever 71 is inserted into a spiral groove 62 and a semicircular block 73 is fixedly installed thereon. The semicircular block 73 slides in contact with the inner wall of the spiral groove 62. The other end of the movable lever 71 is fixedly connected to the rubber disc 72. The rubber disc 72 is connected to the fixed plate 1 by a second spring 74. When the housing 2 pushes the rubber disc 72 and the movable lever 71 to move, the movable lever 71 drives the semicircular block 73 to insert into the spiral groove 62, and causes the winding drum 6 to rotate to release the steel cable 8, and causes the positioning plate 5 to lose tension and abut against the fastening bolt 4. When the housing 2 separates from the rubber disc 72, the second spring 74 pushes the rubber disc 72 and the movable lever 71 to reset. At this time, the semicircular block 73 resets along the inner wall of the spiral groove 62, and causes the winding drum 6 to rotate to wind up the steel cable 8, and causes the positioning plate 5 to separate from the fastening bolt 4.

[0032] One end of the steel cable 8 is fixedly connected to the outer wall of the positioning plate 5, and the other end of the steel cable 8 is wound in the annular groove 61. The steel cable 8 facilitates the connection between the positioning plate 5 and the winding drum 6, thereby facilitating the control of the movement of the positioning plate 5 through the winding drum 6.

[0033] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
