[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides a pressing plate, such as Figure 1 、 Figure 3 and Figure 5 As shown, the relay protection pressure plate includes a base plate 1, a relay protection pressure plate body 2 fixedly mounted on the base plate 1, a connecting column 7 fixedly mounted on the base plate 1, a protective shell 3 arranged on the base plate 1, a fixed shell 8 fixedly mounted on the inner wall of the protective shell 3, a second sealing plate 10 fixedly mounted inside the fixed shell 8, a connecting tube 11 fixedly mounted on the second sealing plate 10, a telescopic rod 18 fixedly mounted on the inner wall of the fixed shell 8, and a fixed block 16 fixedly mounted on the movable end of the telescopic rod 18, and the fixed block 16 passes through the connecting tube 11.

[0028] The protective shell 3 can be installed on the base plate 1 and can also be easily removed from the base plate 1 to facilitate the staff to repair or replace the relay protection pressure plate body 2. When the protective shell 3 is installed on the base plate 1, the connecting column 7 on the base plate 1 needs to be inserted into the connecting tube 11 on the protective shell 3. A groove is provided on the connecting column 7. After the connecting column 7 comes to the inside of the connecting tube 11, the fixing block 16 can be inserted into the groove on the connecting column 7, thereby fixing the protective shell 3 to the base plate 1. At this time, the relay protection pressure plate body 2 is located inside the protective shell 3. The protective shell 3 can reduce the occurrence of other people accidentally touching or misoperating the relay protection pressure plate body 2.

[0029] Furthermore, in order to enable the fixing block 16 to be inserted into the groove on the connecting column 7, as shown in FIG. Figure 3 、 Figure 4 and Figure 7 As shown, one side of the fixed block 16 is fixedly connected to the adjusting block 17, and the telescopic rod 18 is sleeved with a second spring 19, one end of the second spring 19 is fixedly connected to the inner wall of the fixed shell 8, and the other end of the second spring 19 is fixedly connected to one side of the fixed block 16.

[0030] When the protective shell 3 is installed on the base plate 1, the connecting column 7 will be inserted into the interior of the connecting tube 11. Before the fixed block 16 is inserted into the groove on the connecting column 7, the connecting column 7 will come into contact with the fixed block 16 and squeeze the arc-shaped surface of the fixed block 16. The setting of the telescopic rod 18 allows the squeezed fixed block 16 to shrink toward the interior of the fixed shell 8, providing movement space for the connecting column 7. The setting of the second spring 19 allows the second spring 19 to be synchronously compressed when the fixed block 16 shrinks toward the interior of the fixed shell 8. When the groove on the connecting column 7 comes to the fixed block 16, the second spring 19 can release the pressure in an instant, driving the fixed block 16 to be inserted into the groove on the connecting column 7.

[0031] Furthermore, in order to enable the protective shell 3 to be removed from the base plate 1, as shown in FIG. Figure 3 、 Figure 4 and Figure 5 As shown, the interior of the fixed shell 8 is fixedly connected to the first sealing plate 9, the side surface of the connecting tube 11 is slidably connected to the pressure block 12, the side surface of the pressure block 12 slides against the inner wall of the first sealing plate 9, the bottom of the pressure block 12 is fixedly connected to the connecting strip 13, the side surface of the connecting strip 13 fits against the side surface of the adjustment block 17, the bottom of the connecting strip 13 is fixedly connected to the reset plate 14, and the reset plate 14 is slidably connected to the side surface of the connecting tube 11.

[0032] When removing the protective shell 3, it is necessary to press the pressing block 12 downward. The pressing block 12 can slide on the connecting tube 11. The setting of the first sealing plate 9 improves the stability of the pressing block 12 when sliding. When the pressing block 12 slides downward, it can drive the connecting bar 13 to move synchronously. The inclined surface of the connecting bar 13 is in contact with the inclined surface of the adjusting block 17. During the downward movement of the connecting bar 13, the adjusting block 17 will be squeezed, so that the adjusting block 17 and the fixing block 16 will shrink toward the inside of the fixed shell 8, and the fixing block 16 will move out of the groove on the connecting column 7. At this time, by pulling the protective shell 3 upward, the protective shell 3 can be directly removed from the base plate 1.

[0033] In order to enable the connecting strip 13 to automatically reset, Figure 3 、 Figure 4 and Figure 7 As shown, a first spring 15 is sleeved on the connecting tube 11 , one end of the first spring 15 is fixedly connected to the bottom of the reset plate 14 , and the other end of the first spring 15 is fixedly connected to the top of the second sealing plate 10 .

[0034] When removing the protective shell 3, it is necessary to press the pressing block 12 downward. When the pressing block 12 slides downward, it can drive the connecting bar 13 to move synchronously. When the connecting bar 13 moves downward, it can drive the reset plate 14 connected to it to slide downward. When the reset plate 14 slides downward, it can compress the first spring 15. When the pressing block 12 is released, the first spring 15 can release the pressure to drive the reset plate 14, the connecting bar 13 and the pressing block 12 to automatically reset, thereby preventing the connecting bar 13 from affecting the operation of the fixing block 16.

[0035] It should be noted that, in order to improve the stability of the sliding cover 4 when sliding, Figure 1 、 Figure 2 and Figure 6 As shown, the top of the protective shell 3 is slidably connected to a sliding cover 4, and the top of the protective shell 3 is fixedly connected to a limiting block 6. A strip groove is opened on the sliding cover 4, and the side surface of the limiting block 6 fits with the inner wall of the strip groove.

[0036] The sliding cover 4 is used to close the protective shell 3 so that the relay protection pressure plate body 2 can be completely enclosed inside the protective shell 3 to reduce the occurrence of other people accidentally touching or moving the relay protection pressure plate body 2. The sliding cover 4 can slide in the protective shell 3 to open part of the space of the protective shell 3 so that the staff can perform simple operations on the relay protection pressure plate body 2. The opening of the strip groove and the limit block 6 provide the premise for the sliding of the sliding cover 4. The setting of the limit block 6 prevents the sliding cover 4 from separating from the protective shell 3, and at the same time improves the stability of the sliding cover 4 when sliding.

[0037] Furthermore, in order to improve the safety of workers during work, Figure 1 、 Figure 2 and Figure 6As shown, the top of the sliding cover 4 is fixedly connected to the alarm 5 , the bottom of the sliding cover 4 is fixedly connected to the connection terminal 20 , and the top of the base plate 1 is fixedly connected to the power terminal 21 .

[0038] The connecting terminal 20 is connected to the alarm 5, and the power terminal 21 is energized. When the connecting terminal 20 comes into contact with the power terminal 21, the alarm 5 will alert the staff. When the sliding cover 4 is fully closed, the connecting terminal 20 will not come into contact with the power terminal 21. Once other personnel move the sliding cover 4, the connecting terminal 20 at the bottom of the sliding cover 4 will move accordingly and come into contact with the power terminal 21, allowing the alarm 5 to alert the staff.

[0039] 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.
