[0019] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0020] Example 1 An explosion-proof handle with a locking function, such as Figure 1-Figure 5As shown, it includes a handle 1, a base 101 is provided on the lower side of the handle 1, and a locking mechanism is provided in the handle 1, the locking mechanism is used to lock the handle 1, and a hidden mechanism is provided in the handle 1, the hidden mechanism is used to prevent non-power staff from operating the handle 1, thereby improving the safety of the disconnector, and the hidden mechanism includes a sliding frame A201, a special-shaped groove is provided on one side of the handle 1, the sliding frame A201 is horizontally slidably connected in the special-shaped groove, a compression spring A is provided between the front side of the sliding frame A201 and the inner wall of the special-shaped groove, the left and right sides of the sliding frame A201 are symmetrically fixed with deception blocks 202, the sliding frame A201 is symmetrically horizontally slidably connected with an elastic wedge block A203, the special-shaped groove of the handle 1 is horizontally slidably connected with a movable block 204, the front side of the movable block 204 is provided with a compression spring B, the left and right sides of the movable block 204 are symmetrically provided with a card slot, the card slot is used in conjunction with the elastic wedge block A203, and one side of the movable block 204 is fixed with an unlocking block 205.

[0021] like Figure 3-Figure 6 As shown, the hidden mechanism also includes a guide bar 301, which is symmetrically fixed in the special-shaped groove of the handle 1. The guide bar 301 is used in conjunction with the elastic wedge block A203. The guide bar 301 is used to limit the elastic wedge block A203 to prevent the elastic wedge block A203 from escaping from the slot of the movable block 204.

[0022] like Figure 5 As shown, the hidden mechanism also includes a damping block 401, which is symmetrically fixed inside the sliding frame A201. The damping block 401 is used in conjunction with the elastic wedge block A203. When the sliding speed of the elastic wedge block A203 is slow, the damping block 401 will not apply resistance to the elastic wedge block A203.

[0023] like Figure 7 As shown, the locking mechanism includes an elastic telescopic shaft 501, and the elastic telescopic shaft 501 is rotatably connected to the base 101. The telescopic end of the elastic telescopic shaft 501 is fixed to the bottom of the handle 1. The sliding frame B502 is horizontally slidably connected in the special-shaped groove of the handle 1, and is horizontally slidably connected to the mounting plate. The mounting plate is located at the lower side of the sliding frame B502, and a return spring is provided between the rear side of the mounting plate and the bottom of the sliding frame B502. The bottom of the mounting plate is fixedly connected to a vertical shaft 503, and one end of the vertical shaft 503 is fixedly connected to a disc 504. A guide groove is provided on the base 101, and the disc 504 is stuck in the guide groove and slides therein. The guide groove is arranged in an arc shape, and the distance between the left end of the guide groove and the elastic telescopic shaft 501 is smaller than the distance between the right end of the guide groove and the elastic telescopic shaft 501. When the disc 504 slides along the guide groove, it will gradually move away from the elastic telescopic shaft 501.

[0024] like Figure 7As shown, the locking mechanism further includes a U-shaped bar 601 . The U-shaped bar 601 is fixed in the guide groove and is used in conjunction with the disc 504 . The U-shaped bar 601 is used to limit the disc 504 .

[0025] like Figure 7-Figure 9 As shown, the locking mechanism also includes an elastic wedge block B701, and the elastic wedge block B701 used in conjunction with the sliding frame B502 is slidably connected in the special-shaped groove of the handle 1. The elastic wedge block B701 is used to limit the sliding frame B502, and the front side bevel angle of the elastic wedge block B701 is greater than the rear side bevel angle.

[0026] like Figure 7 and Figure 8 As shown, the locking mechanism also includes a locking plate 801, which is vertically slidably connected to the special-shaped groove of the handle 1. A compression spring C is arranged between the bottom of the locking plate 801 and the inner wall of the special-shaped groove. A locking groove is provided at the bottom of the sliding frame B502 for use with the locking plate 801. The locking plate 801 can limit the sliding frame B502 through the locking groove.

[0027] like Figure 10 As shown, it also includes a limiting plate 901, which is fixed to the base 101. The limiting plate 901 is movably connected to the outer wall of the handle 1. The outer wall of the limiting plate 901 is provided with a rectangular groove for use with the sliding frame B502. When the sliding frame B502 is inserted into the rectangular groove, the handle 1 can be limited.

[0028] Initially, the isolating switch is in the connected state, the bottom surface of the sliding frame A201 is higher than the top surface of the rectangular groove of the limit plate 901, and the bottom end of the disc 504 is higher than the guide groove of the base 101. When the isolating switch needs to be temporarily disconnected, the power staff directly turns the handle 1, and the handle 1 drives the elastic telescopic shaft 501 to rotate, thereby disconnecting the isolating switch.

[0029] When the disconnector needs to be closed for a long time and locked, the power worker presses the handle 1 downward, and the handle 1 drives the telescopic shaft of the elastic telescopic shaft 501 to retract, and drives the sliding frame B502 to descend, and drives the vertical shaft 503 to descend through the mounting plate, and the vertical shaft 503 drives the disc 504 to descend. After the sliding frame B502 descends, the bottom surface of the sliding frame B502 and the bottom surface of the rectangular groove of the limit plate 901 are at the same horizontal plane, and the disc 504 is stuck in the guide groove of the base 101 after it descends, and then the handle 1 is rotated counterclockwise, and the handle 1 drives the elastic telescopic shaft 501 to rotate, and drives the sliding frame B502 to move, and drives the vertical shaft 503 to move through the mounting plate, and the vertical shaft 503 drives the disc 504 to slide along the inner wall of the guide groove of the base 101. The guide groove squeezes the outer wall of the disc 504, and the disc 504 is forced to drive the mounting plate to slide to the side away from the sliding frame A201 through the vertical shaft 503. The mounting plate applies a pulling force to the sliding frame B502 through the return spring. It is worth noting that due to the angle characteristics of the rear inclined surface of the elastic wedge block B701, the pulling force applied by the return spring to the sliding frame B502 is less than the squeezing force of the elastic wedge block B701 on the sliding frame B502. The elastic wedge block B701 will not shrink, making the sliding frame B502 unable to move. The return spring is forced to extend, and then the top of the disc 504 contacts the bottom of the U-shaped bar 601. The U-shaped bar 601 can limit the height of the handle 1 through the disc 504, the vertical shaft 503 and the mounting plate to prevent the handle 1 from moving upward during the rotation process. Lifting, thereby ensuring that the bottom surface of the sliding frame B502 and the bottom surface of the rectangular groove of the limiting plate 901 are always in the same horizontal plane, and at this time the power worker does not need to press the handle 1 anymore, but only needs to continue to rotate the handle 1 until the disc 504 contacts the end of the guide groove of the base 101. At this time, the pulling force applied by the return spring to the sliding frame B502 is greater than the squeezing force of the elastic wedge block B701 on the sliding frame B502. The elastic wedge block B701 shrinks and slides under the force and no longer limits the sliding frame B502. The contraction of the return spring drives the sliding frame B502 to slide to the side away from the sliding frame A201, and the rear end of the sliding frame B502 is stuck in the rectangular groove of the limiting plate 901. The rectangular groove limits the handle 1 through the sliding frame B502, so that the handle 1 can no longer be rotated. The elastic wedge block B701 is squeezed by the sliding frame B502 to maintain the contracted state. At the same time, the locking groove of the sliding frame B502 is aligned with the locking plate 801. The compression spring C is released to drive the locking plate 801 to lift and slide upward. After sliding, the locking plate 801 is stuck in the locking groove of the sliding frame B502 to limit the sliding frame B502, so that the sliding frame B502 cannot slide in the special-shaped groove of the handle 1, thereby preventing the sliding frame B502 from escaping from the rectangular groove of the limiting plate 901, thereby completing the locking of the handle 1 and disconnecting the isolating switch. By locking the handle 1, it can prevent the handle 1 from being accidentally touched, causing the isolating switch to be connected, resulting in a safety accident. In addition, there is no need to lock the handle 1 through the above steps. The handle 1 can be locked by simply pressing and turning the handle 1.Greatly improved work efficiency.

[0030] The outer wall of the movable block 204 and the outer wall of the handle 1 form a complete circle. Since the base 101 is often set vertically, the overall explosion-proof handle is also set vertically. At the same time, the handle 1 and the movable block 204 are the same color. If you do not carefully observe the appearance of the handle 1, it is difficult to find that the movable block 204 and the handle 1 are not a whole. When the non-electrical staff wants to turn the handle 1, the attention of the non-electrical staff will be focused on the deception block 202 and the sliding frame B502. Since the sliding frame B502 is limited by the locking plate 801 at this time, the sliding frame B502 cannot move. The non-electrical staff can only move the deception block 202. When the deception block 202 drives the sliding frame A201 to slide to the side close to the sliding frame B502, the compression spring A is forced to shrink, and the unlocking block 205 will not move. The locking plate 801 can still keep the sliding frame B502 limited, and the handle 1 remains locked.

[0031] When the non-electrical staff finds the movable block 204 and presses it, the movable block 204 is forced to drive the unlocking block 205 to move to the side close to the locking plate 801, and the compression spring B is forced to shrink. Then the movable block 204 contacts and squeezes the two elastic wedge blocks A203. When the movable block 204 slides faster, the movable block 204 squeezes the two elastic wedge blocks A203, causing the two elastic wedge blocks A203 to slide away from each other quickly. The damping block 401 applies force to the elastic wedge blocks A203, so that the two elastic wedge blocks A203 can only slide a micro distance. The two elastic wedge blocks A203 are squeezed by the movable block 204. The sliding frame A201 is driven to slide toward the side close to the sliding frame B502, and the compression spring A is forced to shrink. Due to the small size of the movable block 204, the movable block 204 can only be pressed by fingers, and the distance of pressing the movable block 204 by fingers is limited. There is still a gap between the unlocking block 205 and the locking plate 801, and the locking plate 801 can still maintain the limit on the sliding frame B502. When the movable block 204 is no longer pressed, the compression spring B is released to drive the movable block 204 to slide. At the same time, the compression spring A is released to drive the sliding frame A201 to slide and reset. The sliding frame A201 drives the two elastic wedge blocks A203 to move and reset.

[0032] When the sliding speed of the movable block 204 is slow, the two elastic wedge blocks A203 are squeezed by the movable block 204 and slide away from each other slowly. The damping block 401 does not apply force to the elastic wedge block A203, and the elastic wedge block A203 is forced to shrink and slide. It is worth noting that the elastic force of the compression spring A is much greater than the elastic wedge block A203. When the elastic wedge block A203 is squeezed, the sliding frame A201 will not move until the elastic wedge block A203 is aligned with the card slot of the movable block 204, and the two elastic wedge blocks A203 are released and respectively snapped into the movable block 2 04, when the movable block 204 is no longer pressed, the compression spring B is released to drive the movable block 204 to slide, and the two slots of the movable block 204 squeeze the two elastic wedge blocks A203 respectively, and the elastic wedge blocks A203 shrink and slide under the force until the compression spring B is completely released to drive the movable block 204 to slide and reset, and the movable block 204 passes over the elastic wedge blocks A203 and no longer contacts it. The two elastic wedge blocks A203 are released to slide and reset, thereby further preventing the handle 1 from rotating, causing a safety accident when the isolating switch is connected.

[0033] When the disconnector needs to be connected, the power worker holds the handle 1 and pushes the movable block 204 to slide to the side close to the sliding frame A201 with one finger, so that the two elastic wedge blocks A203 are stuck in the two slots of the movable block 204, and then the deception block 202 is quickly pushed to the side close to the sliding frame B502. The deception block 202 drives the two elastic wedge blocks A203 to move quickly through the sliding frame A201. At this time, the two elastic wedge blocks A203 are squeezed by the slots of the movable block 204, and the slots of the movable block 204 exert a reaction force on the two elastic wedge blocks A203, causing the elastic wedge blocks A203 to slide quickly. At this time, the damping block 401 exerts resistance on the elastic wedge block A203, and the elastic wedge block A203 only The elastic wedge block A203 can slide a micro distance, and the elastic wedge block A203 cannot be separated from the slot of the movable block 204, and exerts a reaction force on the slot of the movable block 204. The movable block 204 is forced to slide toward the side close to the sliding frame B502, and drives the unlocking block 205 to move. Then the elastic wedge block A203 contacts the guide bar 301, and the inclined surface of the guide bar 301 squeezes the elastic wedge block A203, so that the elastic wedge block A203 is released to slide, and the elastic wedge block A203 squeezes the slot of the movable block 204, so that the movable block 204 drives the unlocking block 205 to slide relative to the sliding frame A201 toward the side close to the locking plate 801, and the guide bar 301 limits the elastic wedge block A203, further preventing the elastic wedge block A203 from separating from the movable block 20 4, then the inclined surface of the unlocking block 205 contacts and squeezes the top surface of the locking plate 801, and the locking plate 801 slides downward under the force, and the compression spring C is forced to shrink. After the locking plate 801 falls, it disengages from the lock slot of the sliding frame B502, and the sliding frame B502 can move after being freed from the restriction. Then, the sliding frame B502 is pushed to the side close to the unlocking block 205, and the sliding frame B502 is forced to slide along the special-shaped groove of the handle 1 and disengage from the rectangular groove of the limiting plate 901. The reset spring is forced to extend, and the sliding frame B502 is freed from the restriction of the rectangular groove to enable the handle 1 to move. Then the deception block 202 is released, the compression spring A is released, and the deception block 202 is driven to move and reset through the sliding frame A201. At the same time, the sliding frame A201 drives two elastic wedges The two elastic wedge blocks A203 are released from the restriction and slide back to the original position until the movable block 204 slides back to the original position, and then the handle 1 is turned clockwise.Handle 1 drives slide frame B502 to move, and through the mounting plate and vertical shaft 503, it drives disc 504 to slide along the guide groove of base 101. The return spring gradually contracts until disc 504 contacts the end of the guide groove of base 101, connecting the disconnector. At this point, disc 504 no longer contacts U-shaped bar 601. Disconnected from its restraint, disc 504 allows handle 1 to move vertically. The retractable end of the elastic retractable shaft 501 is released, driving handle 1 upward and back to its original position. Handle 1, through the mounting plate and vertical shaft 503, drives disc 504 upward and back to its original position, thus completing the unlocking and resetting of handle 1.

[0034] Through the above steps, non-electrical personnel can be effectively prevented from connecting the isolating switch. Only electric personnel who understand the working principle and structure of the present invention can operate it, which greatly improves the safety of the isolating switch.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.
