[0045] Example 1

[0046] Reference Figure 1-Figure 4 , provides an inlet bushing of an environmentally friendly gas ring main unit gas box, including a fixing component 100, which is plugged into a cabinet body X;

[0047] The plug-in component 200 is plugged into the fixed component 100 and has a high-voltage conductor 300 disposed therein;

[0048] The cabinet X is provided with a circular hole corresponding to the fixing component 100, and the fixing component 100 is provided with a cavity corresponding to the plug-in component 200, and the plug-in component 200 can be fixed to the outside of the cabinet X through the fixing component 100;

[0049] When in use, the fixing component 100 is first plugged into the inner side of the cabinet X by making the fixing component 100 correspond to the circular hole of the cabinet X, and then the plug-in component 200 is plugged into the fixing component 100. The fixing component 100 cooperates with the plug-in component 200 so that the plug-in component 200 can be fixed on the outer side of the cabinet X after being plugged into the fixing component 100. At the same time, a high-voltage conductor 300 is provided in the fixing component 100, and then the bushing can be fixed on the cabinet X only by plugging.

[0050] Furthermore, the fixing component 100 includes a sleeve 101 inserted into the cabinet X, and a retaining ring 102 is fixedly provided on the outer side of the sleeve 101; the plug-in component 200 includes a round rod 201 inserted into the sleeve 101, and the high-voltage conductor 300 is arranged in the round rod 201; the retaining ring 102 can limit the depth of the insertion between the sleeve 101 and the cabinet X;

[0051] The sleeve 101 is in the shape of a circular tube as a whole. When the sleeve 101 is plugged into the cabinet X, one side of the retaining ring 102 contacts the inner wall of the cabinet X, so that the sleeve 101 cannot move further, and a sealing member can be arranged between the two to improve the air tightness of the cabinet X and the sleeve. A baffle is arranged at the end of the sleeve located in the cabinet X, and a through hole is opened in the baffle so that the high-voltage conductor 300 can extend out of the sleeve 101, which is convenient for connecting the equipment with the high-voltage conductor 300. A plurality of sheds are arranged on the outer side of the sleeve located in the cabinet X.

[0052] The round rod 201 can be inserted into the sleeve, and a seal can be set between the end of the round rod 201 and the inner wall of the sleeve to ensure the air tightness between the two. At the same time, a high-voltage conductor 300 is provided in the middle of the round rod 201. The high-voltage conductor 300 can be set in the round rod 201 by means of threaded connection, etc. A metal shielding cover can be fixedly set in the round rod 201, and the metal shielding cover is sleeved with the high-voltage conductor 300.

[0053] Furthermore, a snap-fit ​​member 103 is provided at the end of the sleeve 101; wherein the retaining ring 102 cooperates with the snap-fit ​​member 103 to fix the sleeve 101 on the cabinet body X;

[0054] A plurality of sets of fasteners 103 are fixedly provided at the end of the sleeve 101. When the sleeve 101 is plugged into the cabinet X, after the fasteners 103 can be fully extended out of the cabinet X, the retaining ring 102 abuts against the inner wall of the cabinet X, and the two cooperate to fix the sleeve 101 on the inner side of the cabinet X, and then the sleeve 101 is installed.

[0055] Furthermore, the fastener 103 is provided with a first inclined surface 103a, and the fastener 103 has toughness; wherein the first inclined surface 103a abuts against the circular hole, so that the multiple groups of fasteners 103 shrink and come together to pass through the cabinet X;

[0056] The connection between the clip 103 and the sleeve 101 is relatively thin, so that the end of the clip 103 has a certain toughness, can be deformed when squeezed, and reset after the external force squeezing is lost. The clip 103 is provided with a first inclined surface 103a at one end close to the outer side of the cabinet X. When the sleeve 101 is plugged into the cabinet X, the first inclined surface 103a first contacts the inner wall of the circular hole. At the first inclined surface 103a, multiple groups of clips 103 shrink toward the axis of the sleeve 101. When the clip 103 is completely pushed out of the cabinet X, it can automatically pop open and reset. At this time, the retaining ring 102 contacts the inner wall of the cabinet X, so that the sleeve 101 is fixed to the side wall of the cabinet X by the two, and then the subsequent installation of the plug-in component 200 can be completed.

[0057] Furthermore, a locking piece 202 is provided on the outside of the round rod 201; when the round rod 201 is plugged into the sleeve 101, the locking piece 202 is sleeved on the outside of the buckle 103, thereby enabling the round rod 201 to be fixed in the sleeve 101;

[0058] After the sleeve 101 is fixed, the round rod 201 is inserted into the sleeve 101. The diameter of the round rod 201 corresponds to the cavity diameter of the sleeve 101. During the process of the round rod 201 being inserted into the sleeve 101, the locking piece 202 can be gradually engaged with the snap-on piece 103. When the round rod 201 is inserted into place, its end contacts the end of the inner wall of the sleeve 101, the locking piece 202 is completely engaged with the snap-on piece 103, and the end of the locking piece 202 contacts the outer wall of the cabinet X.

[0059] Furthermore, the locking member 202 includes a ring sleeve 202a fixedly arranged outside the round rod 201, and a circular ring 202b is arranged at the end of the ring sleeve 202a; the circular ring 202b contacts the first inclined surface 103a, and the buckle 103 shrinks and moves closer, so that the ring sleeve 202a can be sleeved with the buckle 103;

[0060] An opening is provided at one end of the ring sleeve 202a close to the cabinet X, so that the fastener 103 can enter the interior thereof. A circular ring 202b is fixedly provided at the end of the ring sleeve 202a. When the round rod 201 moves to be plugged in the sleeve, the circular ring 202b contacts the first inclined surface 103a, so that the fastener 103 is brought together and contracted. When the round rod 201 is plugged in, the fastener 103 enters the ring sleeve 202a. An annular groove 203 is provided on the outer side of the round rod 201 along its axial direction. The annular groove 203 is communicated with the ring sleeve 202a, so that the fastener 103 has a certain contraction space. At the same time, a cavity is provided in the ring sleeve 202a, so that after the ring sleeve 202a and the fastener 103 are sleeved, the fastener 103 can be elastically reset.

[0061] Furthermore, a locking groove 103 b is formed on the locking member 103 ; after passing through the first inclined surface 103 a , the locking member 202 can abut against the locking groove 103 b , thereby fixing the round rod 201 in the sleeve 101 .

[0062] A slot 103b is provided on one side of the fastener 103 close to the sleeve 101. A plurality of fixed blocks 202c are fixedly provided on one side of the circular ring 202b located inside the ring sleeve 202a. The slot 103b corresponds to the fixed blocks 202c. When the ring sleeve 202a is sleeved with the fastener 103, the fixed blocks 202c are driven to move synchronously through the circular ring 202b. When the ring sleeve 202a is sleeved with the fastener 103 and the fastener 103 is reset, the fixed blocks 202c enter the slot 103b. The periphery of the fixed blocks 202c contacts the inner wall of the slot 103b. At this time, the ring sleeve 202a is fixed and cannot slide. Then, the round rod 201 is fixed in the sleeve 101 through the ring sleeve 202a.

[0063] A plurality of limit strips 104 are arranged in the inner wall of the sleeve 101, and limit grooves corresponding to the limit strips 104 are arranged on the outer side of the round rod 201. When the round rod 201 needs to be plugged into the sleeve 101, the limit strips 104 need to be aligned with the limit grooves to ensure that the fastener 103 can correspond to the position of the slot 103b.

[0064] By providing the bayonet member and the locking member 202 , the sleeve 101 and the round rod 201 can be easily installed on the cabinet X without the need for auxiliary tools, thereby achieving rapid installation of the incoming line bushing and improving installation efficiency.

[0065] Example 2

[0066] In the above embodiment, the incoming line sleeve 101 can be quickly installed on the cabinet X, but cannot be removed from the cabinet X, which is inconvenient when repairing or inspecting the incoming line sleeve 101.

[0067] Reference Figure 1-Figure 6 , this embodiment is different from the first embodiment in that: it also includes a sliding member 400, which is arranged in the ring sleeve 202a and extends to the outside of the ring sleeve 202a; the buckle 103 is provided with a second inclined surface 103c;

[0068] When the sliding member 400 moves in the first direction, it can contact with the second inclined surface 103c, so that the locking member 103 is contacted and retracted to be separated from the locking member 202;

[0069] The second inclined surface 103c is provided on the side of the fastener 103 close to the sleeve 101. When the fastener 103 is fully extended out of the cabinet X, the end of the second inclined surface 103c is aligned with the outer surface of the cabinet X. When the sleeve 101 is pulled in the first direction, the first direction is Figure 1 In the direction indicated by the middle arrow, the second inclined surface 103c contacts the circular hole, so that the buckle 103 shrinks and moves closer, and then the buckle 103 can pass through the circular hole, and the sleeve 101 can be removed; the sliding component 400 includes an annular member 401, and a plurality of connecting plates 402 fixedly arranged on the annular member 401, and the end of the connecting plate 402 extends out of the ring sleeve 202a connected with a group of pull rings 403, and the inner wall of the ring sleeve 202a is provided with a stopper 404 that cooperates with the annular member 401, and the stopper 404 can limit the sliding of the annular member 401;

[0070] Before the ring sleeve 202a is sleeved with the buckle 103, the ring member 401 is moved to the position closest to the circular ring 202b. When the ring sleeve 202a is sleeved with the buckle 103, the ring member 401 needs to maintain this position and be sleeved with the buckle 103. After the ring sleeve 202a is completely sleeved with the buckle 103, the ring member 401 is in contact with the surface of the second inclined surface 103c. At this time, the ring member 401 is restricted by the buckle 103 and will not move without external force.

[0071] When the round rod 201 needs to be disassembled, the pull ring 403 is pulled in the second direction, which is the opposite direction of the first direction. The pull ring 403 drives the annular member 401 to move through the connecting plate 402, and the annular member 401 contacts the second inclined surface 103c, so that the buckle 103 is deformed and shrinks and moves closer. At this time, the fixed block 202c gradually disengages from the slot 103b. When the annular member 401 is pulled and contacts the stopper 404, the fixed block 202c is completely disengaged from the slot 103b. The contact of the stopper 404 enables the buckle 103 to maintain this state. The annular member 401 drives the ring sleeve 202a to slide and disengage from the buckle 103 through the stopper 404, and by continuously pulling the pull ring 403, the round rod 201 can be pulled out of the sleeve 101, and then the round rod 201 can be removed from the sleeve 101.

[0072] When the sleeve 101 and the round rod 201 need to be removed at the same time, after the round rod 201 is removed according to the above operation, the sleeve 101 is pulled from the inner side of the cabinet X in the first direction so that the second inclined surface 103 c contacts the round hole, and then the sleeve 101 is removed from the cabinet X.

[0073] The rest of the structure is the same as that of Example 1.

[0074] By setting the sliding component 400, the incoming line sleeve can be removed from the outside of the cabinet X. When operating, the staff can directly operate outside the cabinet X, which is more convenient and quick. It can also avoid maintenance personnel from directly contacting the high-voltage components inside the gas box, reducing the risk of electric shock and arc. At the same time, the device can realize the rapid disassembly and assembly of the incoming line sleeve 101, thereby improving the working efficiency.

[0075] Example 3

[0076] In the above embodiment, when the ring sleeve 202a is sleeved with the buckle 103, the interference between the ring sleeve 202a and the buckle 103 easily causes the second inclined surface 103c to interfere with the cabinet X, and then the sleeve 101 moves into the cabinet X, making it impossible to complete the installation.

[0077] Reference Figure 1-Figure 8 This embodiment is different from the above embodiment in that it also includes a positioning component 500, which is arranged outside the round rod 201; when the round rod 201 moves in the sleeve 101 in the second direction, the positioning component 500 can be plugged with the buckle 103, so that the sleeve 101 will not slide in the second direction;

[0078] The buckle 103 is provided with a positioning groove 103d corresponding to the positioning component 500;

[0079] A plurality of groups of sliding grooves 204 are radially provided on the outer side of the round rod 201, and a plurality of groups of positioning grooves 103d are equidistantly distributed along the axial direction of the round rod 201. The sliding grooves 204 are located on the inner wall of the annular groove 203. The positioning component 500 includes a sliding seat 501 slidingly arranged in the sliding groove 204, and a rotating rod 502 is rotatably connected to the top of the sliding seat 501. An arc plate 503 is fixedly arranged between the plurality of groups of sliding seats 501, and the arc plate 503 fits the inner wall of the annular groove 203, so that the plurality of groups of sliding seats 501 will not be separated from the sliding groove 204. At the same time, the sliding groove 20 4, a spring 504 is fixedly provided at one end away from the sleeve 101, and the spring 504 is located between the inner wall of the sliding groove 204 and the sliding seat 501. A positioning groove 103d corresponding to the rotating rod 502 is provided at the bottom of the buckle 103, and the bottom end of the positioning groove 103d is aligned with the end of the sleeve 101. A positioning block 505 is provided at the connection between the rotating rod 502 and the sliding seat 501, and an arc groove 506 corresponding to the positioning block 505 is provided on the fixed axis of the sliding seat 501. The cooperation between the positioning block 505 and the arc groove 506 can limit the angle of rotation of the quasi-dry.

[0080] In the initial state, the spring 504 abuts against the end of the sliding seat 501 located in the sliding groove 204 close to the sleeve 101, and the rotating rod 502 rests on the edge of the annular groove 203 and extends out of the annular groove 203. When the round rod 201 is plugged into the sleeve 101, the end of the rotating rod 502 abuts against the end of the sleeve 101. Due to the abutment of the spring 504 on the sliding seat 501, the sliding seat 501 will not move at this time, so that the rotating rod 502 rotates first and gradually inserts into the positioning groove 103d until the positioning block 505 abuts against the end of the arc groove 506. At this time, the rotating rod 502 rotates When the rotating rod 502 is at the maximum angle, the outer side of the rotating rod 502 contacts the top of the positioning groove 103d, and the end of the rotating rod 502 contacts the surface of the cabinet X. After the rotating rod 502 is inserted into the positioning groove 103d, the round rod 201 continues to move so that the ring sleeve 202a is sleeved with the buckle 103. During this process, since the rotating rod 502 is stuck in the positioning groove 103d, the sliding seat 501 slides in the sliding groove 204, and the rotating rod 502 is limited so that the ring sleeve 202a contacts the buckle 103, the sleeve 101 will not move into the cabinet X until the ring sleeve 202a is completely sleeved with the buckle 103.

[0081] When the round rod 201 needs to be disassembled, when the round rod 201 is pulled in the second direction to disengage from the sleeve 101, the rotating rod 502 can be driven to rotate again to disengage from the positioning groove 103d, thereby making the round rod 201 easily disassembled.

[0082] The rest of the structure is the same as that of Example 2.

[0083] By providing the positioning component 500 , the sleeve 101 is prevented from slipping when the round rod 201 is installed, and the installation of the round rod 201 can be ensured, so that the incoming sleeve 101 can be stably installed.
