[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] The utility model provides a warning sign for power transformation and distribution equipment, which can tightly connect the warning plate with the handle of the power transformation and distribution equipment to prevent the warning sign from accidentally sliding off the power transformation and distribution equipment and losing its warning function.

[0031] Figure 1 This is a structural diagram of a warning sign for power distribution equipment from one perspective in one embodiment of the present application; Figure 2 This is a schematic diagram of the internal structure of the locking assembly in the previous embodiment of this application. Figure 1-2 As shown, an embodiment of the present application provides a warning sign 100 for power transformer and distribution equipment. The warning sign 100 for power transformer and distribution equipment includes a plate body 10, a locking assembly 20, and a hanging arm 30. The plate body 10 is used to display warning information. The locking assembly 20 includes a connecting block 21, a locking pin 22, and a first elastic return member 23. The connecting block 21 is fixedly connected to the plate body 10. The locking pin 22 and the first elastic return member 23 are both arranged in the connecting block 21. The locking pin 22 includes a hinged end and a limit end opposite to each other along its own length direction, and the hinged end is hinged to the connecting block 21. One end of the first elastic return member 23 is connected to the connecting block 21, and the other end of the first elastic return member 23 is connected to the locking pin 22. The hanging arm 30 is arc-shaped, and the hanging arm 30 includes a first end and a second end along its own length direction, and the first end is hinged to the connecting block 21. The second end passes through the connecting block 21. The hanging arm 30 is provided with a circumferential limiting portion 31 , and the circumferential limiting portion 31 and the limiting end are limited along the circumference of the hanging arm 30 .

[0032] It should be noted that the arm 30 is provided with a circumferential limit portion 31, which specifically means that the arm 30 is provided with a limit portion along the circumference of the arc, that is, along the length direction of the arm 30. It is understandable that the arm 30 can be rigid or flexible.

[0033] According to the warning sign 100 for power distribution equipment in the embodiment of the present application, when the warning sign needs to be installed on the power distribution equipment, the first end of the hanging arm 30 is rotated around the hinge point so that the second end is close to the handle of the power distribution equipment, the second end is passed around the handle, and the second end of the hanging arm 30 is passed through the connecting block 21. Since the hanging arm 30 is circumferentially provided with a circumferential limiting portion 31, the circumferential limiting portion 31 contacts the first limiting end of the locking pin 22. During this process, the locking pin 22 is subjected to an external force, and the first elastic return member 23 is deformed. When the external force disappears, the first elastic return member 23 pushes the locking pin 22 back to its original position. At this time, the limiting end is stuck in the circumferential limiting portion 31, thereby fixing the hanging arm 30, ensuring that the warning sign will not fall off or loosen easily, and improving the safety and stability of the warning sign.

[0034] like Figure 1-2 As shown, in some embodiments, a first channel 24 is provided inside the connecting block 21. The locking pin 22 and the first elastic return member 23 are provided in the first channel 24. The second end of the hanging arm 30 passes through the first channel 24.

[0035] In this embodiment, by providing a first channel 24 within the connecting block 21 and arranging the locking pin 22 and the first elastic return member 23 within this channel, the entire warning sign is made more compact. The first channel 24 also enhances the stability of the connection between the locking pin 22 and the hanging arm 30. When the second end of the hanging arm 30 passes through the first channel 24 and engages with the locking pin 22, the first channel 24 provides a more solid support structure for this engagement, thereby preventing the hanging arm 30 from shaking or falling off when subjected to force.

[0036] like Figure 1-2 As shown, in some embodiments, the circumferential limiting portion 31 includes a plurality of limiting teeth or limiting grooves spaced apart along the length direction of the hanging arm 30 itself.

[0037] In this embodiment, when the second end of the hanging arm 30 passes through the connecting block 21, and the locking end of the locking pin 22 abuts against the limiting teeth or limiting grooves provided on the trailer arm, since the limiting teeth or limiting grooves are spaced apart along the length direction of the hanging arm 30, the hanging arm 30 can adapt to components such as handles or brackets of power distribution equipment of different sizes, thereby improving the versatility and flexibility of the warning sign, so that it can be widely used in various power distribution equipment.

[0038] like Figure 2 As shown, in some embodiments, the limiting end of the locking pin 22 is provided with a limiting tooth groove that matches the limiting tooth or a limiting protrusion that matches the limiting groove.

[0039] In this embodiment, when the circumferential limiting portion 31 of the hanging arm 30 engages the limiting end of the locking pin 22, the limiting tooth groove or limiting projection securely engages the limiting tooth or limiting groove, thereby achieving a stable locking effect. This design ensures that the warning sign is not easily dislodged when subjected to external forces, thereby improving its durability and reliability.

[0040] like Figure 2 As shown, in some embodiments, the locking assembly 20 further includes a push rod 25. One end of the push rod 25 is connected to the locking pin 22, and the other end of the push rod 25 passes through the connecting block 21 from the first channel 24 and is slidably connected to the connecting block 21.

[0041] In this embodiment, by pushing the rod 25 , the user can easily release the locking pin 22 to separate it from the circumferential limiting portion 31 of the hanging arm 30 , thereby achieving convenient disassembly.

[0042] like Figure 3 As shown, and see Figure 1As shown, in some embodiments, the warning sign 100 for power transformer and distribution equipment further includes a support assembly. The support assembly includes: a vertical pole 41, a plurality of support legs 42, a plurality of connecting rods 43, and a sliding sleeve 44. One end of the vertical pole 41 is connected to the plate body 10, and the plurality of support legs 42 correspond one-to-one with the plurality of connecting rods 43. The top ends of the plurality of support legs 42 are spaced apart along the same circumference and are hinged to the vertical pole 41. The sliding sleeve 44 is sleeved on the vertical pole 41, and one end of each connecting rod is hinged to the support leg, and the other end of each connecting rod is hinged to the sliding sleeve 44.

[0043] In this embodiment, when the power distribution equipment does not have a warning plate to be hung, the position of the sliding sleeve 44 on the vertical pole 41 can be adjusted so that the connecting rod can change the angle between the multiple legs and the ground. That is, the sliding sleeve 44 is slid relative to the vertical pole 41, so that the connecting rod pushes the legs to open, so that the warning sign can be placed stably on the ground, thereby improving the versatility and practicality of the warning sign 100 for power distribution equipment.

[0044] like Figure 3-4 As shown, and see Figure 1 As shown, in some embodiments, the vertical rod 41 is a pipe. The support assembly further includes a first limiting post 45 and a second elastic return member 46. The second elastic return member 46 is disposed within the vertical rod 41. The first limiting post 45 is disposed on at least one end of the second elastic return member 46. One end of the limiting post is fixedly connected to the second elastic return member 46, and the other end of the limiting post protrudes radially from the vertical rod 41.

[0045] In this embodiment, when inspecting power distribution equipment without handles, the first limiting post 45 is pushed to retract into the vertical pole 41. The sliding sleeve 44 is then pushed to slide on the vertical pole 41, causing the sliding sleeve 44 to drive the support legs to open via the connecting rod. After the sliding sleeve 44 slides past the first limiting post 45, the second elastic return member 46 drives the first limiting post 45 to return to its original position. At this time, the first limiting post 45 limits the sliding sleeve 44, preventing it from sliding upward, thereby preventing the support legs from accidentally retracting.

[0046] like Figure 5 As shown, and see Figure 1 and Figure 3 As shown, in some embodiments, the support assembly further includes a sleeve 47, a positioning post 48, and a third elastic reset member 49. The sleeve 47 is connected to the plate body 10, and the sleeve 47 is slidably connected to the vertical rod 41. The sleeve 47 is provided with a plurality of through holes spaced apart along its length. The third elastic reset member 49 is disposed inside the vertical rod 41, and a positioning post 48 is provided on at least one end of the third elastic reset member 49. One end of the positioning post 48 is fixedly connected to the third elastic reset member 49, and the other end of the positioning post 48 protrudes from the vertical rod 41 in the radial direction of the vertical rod 41.

[0047] In this embodiment, when the height of the board body 10 needs to be adjusted, the user can apply external force to retract the positioning post 48 into the interior of the vertical rod 41, thereby releasing the lock on the sleeve 47. The sleeve 47 can then be slid up and down along the length of the vertical rod 41 until the desired height is reached. When the sleeve 47 reaches the target position, the user releases the external force on the positioning post 48, and the third elastic return member 49 pushes the positioning post 48 to protrude radially along the vertical rod 41, inserting it into the corresponding through-hole on the sleeve 47, thereby achieving the fixation and positioning of the sleeve 47, and then fixing the height of the board body 10. Through the sliding connection between the sleeve 47 and the vertical rod 41, the user can easily adjust the height of the board body 10 to adapt to different sight heights and working environment requirements.

[0048] like Figure 5 As shown, and see Figure 1 and Figure 3 As shown, in some embodiments, the upright 41 is hingedly connected to the plate body 10 via a sleeve 47. The warning sign 100 for power transformer and distribution equipment further includes a support rod 50 and a plurality of stoppers 60. The stoppers 60 are spaced apart along the length of the plate body 10. One end of the support rod 50 is hingedly connected to the sleeve 47, while the other end of the support rod 50 abuts against the stopper. The length direction is perpendicular to the rotation direction of the plate body 10.

[0049] In this embodiment, when the tilt angle of the panel 10 needs to be adjusted, the user manually rotates the panel 10 about the hinge point between the sleeve 47 and the upright 41. When the panel 10 is rotated to the desired angle, one end of the support rod 50 abuts against a stopper located on the panel 10, providing support and limiting the rotation angle of the panel 10. By adjusting the position or number of the stoppers, the user can precisely control the tilt angle of the panel 10 to meet different working environments and requirements.

[0050] like Figure 2 、 Figure 4 、 Figure 5 As shown, in some embodiments, the first elastic return member 23 is a spring. And / or the second elastic return member 46 and the third elastic return member 49 are both U-shaped springs. Springs and U-shaped springs are easy to manufacture and purchase, reducing manufacturing costs and facilitating installation and replacement.

[0051] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
