[0035] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments.

[0036] As Figures 1 - 10 shown, a dry-type transformer connection and support assembly includes a support frame 1; the support frame 1 is used to directly connect to an external installation position, and has installation holes thereon; it further includes: A clamp 3, the number of the clamps 3 is two, and the two clamps 3 are connected by a pulling plate 2; an iron core 11 is clamped and installed between the two clamps 3; A plurality of perforations 1101 for the screw 303 to pass through are provided in both the upper and lower parts of the iron core 11; At the bottom of the fixture 3 at the top of the pull plate 2 and at the top of the fixture 3 at the bottom of the pull plate 2, two sets of cushion blocks 4 are respectively arranged; a coil winding 12 is clamped and installed between the two sets of cushion blocks 4; among them, the cushion block 4 at the bottom of the coil winding 12 is directly fixed on the tops of the first clamping plate 301 and the second clamping plate 302 on the fixture 3; the cushion block 4 at the top of the coil winding 12 adopts a height-adjustable design. Specifically, a stud is fixed at the top of the cushion block 4, and through holes are opened on the first clamping plate 301 and the second clamping plate 302 of the fixture 3 above the pull plate 2. The stud passes through the through holes, and a nut member is threadedly connected to the stud, and the nut member is located above the through holes. By screwing the nut member, the length of the stud extending below the through holes can be adjusted, so as to adjust the height of the cushion block 4, and the distance between the two sets of cushion blocks 4 can be adjusted to clamp the coil winding 12.

[0038] As Figure 3 shown, as a specific technical solution, the fixture 3 includes a first clamping plate 301 and a second clamping plate 302; first through holes are opened on both the first clamping plate 301 and the second clamping plate 302, a screw rod 303 is inserted into the first through holes, nut 304 are threadedly connected to both ends of the screw rod 303, and the nuts 304 at both ends of the screw rod 303 are respectively pressed against the outer sides of the first clamping plate 301 and the second clamping plate 302. Gaskets 305 for fitting with the iron core 11 are arranged on the inner sides of the first clamping plate 301 and the second clamping plate 302.

[0039] The fixture 3 is used to clamp the iron core 11. Specifically, the top and bottom of the iron core 11 are clamped by two sets of fixtures 3; the clamping process is as follows. After the screw rod 303 passes through the through hole 1101 on the iron core 11, both ends of the screw rod 303 respectively pass through the first through holes on the first clamping plate 301 and the second clamping plate 302. Then nuts 304 are screwed onto both ends of the screw rod 303. The nuts 304 press against the outer sides of the first clamping plate 301 and the second clamping plate 302. The gaskets 305 on the first clamping plate 301 and the second clamping plate 302 are respectively pressed against the front and back of the iron core 11 to complete the clamping.

[0040] Before screwing the nuts 304 onto both ends of the screw rod 303, washers need to be sleeved on both ends of the screw rod 303 so that when the nuts 304 are pressed, the first clamping plate 301, the second clamping plate 302 and the nuts 304 have washers to prevent the nuts 304 from directly contacting the first clamping plate 301 and the second clamping plate 302.

[0041] After the two sets of jigs 3 clamp the iron core 11, the two sets of cushion blocks 4 are used to clamp the coil winding 12.

[0042] As Figures 6 - 7 shown, as a specific technical solution, it further includes a plug-in component 7; the plug-in component 7 includes an insertion cylinder 701, a second jack 1103 is opened at the bottom of the iron core 11, the insertion cylinder 701 is connected to the second jack 1103 in a clearance fit manner, a positioning portion is arranged on one side of the top of the insertion cylinder 701, a positioning groove 1104 is opened on one side of the top of the second jack 1103, and the positioning portion is inserted into the positioning groove 1104.

[0043] As Figures 6 - 7 shown, as a specific technical solution, the positioning portion includes a fixed cylinder 709; a hole body is opened on one side of the top of the insertion cylinder 701, the fixed cylinder 709 is fixedly fitted and installed in the hole body, one end of the fixed cylinder 709 is located on the outer wall of the insertion cylinder 701, and a second through hole is opened at the end of the fixed cylinder 709 located on the outer wall of the insertion cylinder 701. A piston 712 is connected in the fixed cylinder 709 in a matching manner, the piston 712 is fixedly connected with a positioning column 710, the positioning column 710 penetrates through the second through hole, and the positioning column 710 is connected to the positioning groove 1104 in a clearance fit manner. A second spring 711 is arranged in the fixed cylinder 709, and the piston 712 is elastically connected to the inner wall of the fixed cylinder 709 through the second spring 711.

[0044] A ventilation hole 1102 is opened on the side wall of the iron core 11, and the ventilation hole 1102 communicates with the positioning groove 1104.

[0045] As Figure 7 shown, as a specific technical solution, a movable seat 702 is arranged in the insertion cylinder 701. A sealing sleeve 703 is fixedly sleeved on the cylindrical surface of the movable seat 702, and the outer ring of the sealing sleeve 703 is connected to the inner wall of the insertion cylinder 701 in a matching manner. The top of the movable seat 702 is fixedly connected with a movable column 704, and the movable column 704 is connected to a third through hole opened at the top end of the insertion cylinder 701 in a clearance fit manner. The movable seat 702 is elastically connected to the top inner wall of the insertion cylinder 701 through a first spring 705. An air duct 706 is arranged in the cylinder wall of the insertion cylinder 701, the bottom end of the air duct 706 is communicated with the bottom of the insertion cylinder 701, the top end of the air duct 706 is fixedly communicated with an air pipe 707, and the air pipe 707 is fixedly communicated with one end of the fixed cylinder 709 located in the insertion cylinder 701; a retaining ring 708 is fixedly installed on the inner wall of the insertion cylinder 701, and the retaining ring 708 is located above the movable seat 702.

[0046] After the spacer block 4 clamps the coil winding 12, the iron core 11 is directly placed on the base 6, specifically by inserting the insertion cylinder 701 into the second jack 1103; in the state where the insertion cylinder 701 is not inserted into the second jack 1103, as Figure 5 shown, the movable column 704 extends from the top of the insertion cylinder 701, while the positioning column 710 is received in the fixed cylinder 709, and the top surface of the movable seat 702 contacts the bottom surface of the retaining ring 708; during the process of inserting the insertion cylinder 701 into the second jack 1103, the insertion cylinder 701 and the positioning portion thereon enter into the second jack 1103 (at this time, the movable column 704 has not contacted the top surface of the second jack 1103), and then continue to insert. The movable column 704 contacts the top surface of the second jack 1103, and then the insertion cylinder 701 continues to insert into the second jack 1103. Blocked by the top surface of the second jack 1103, the movable column 704 moves into the insertion cylinder 701, the movable column 704 drives the movable seat 702 to move downward, and at the same time stretches the first spring 705. The movable seat 702 compresses the gas in the insertion cylinder 701 to increase the pressure. Through the air passage 706 and the air pipe 707, the pressurized gas is input into the fixed cylinder 709. The air pressure acts on the piston 712, so that the positioning column 710 presses against the wall of the second jack 1103. When the insertion cylinder 701 is completely inserted into the second jack 1103, as Figures 6 - 7 shown, the positioning column 710 is aligned with the positioning groove 1104. Under the action of air pressure, the piston 712 and the positioning column 710 move together, and the positioning column 710 is inserted into the positioning groove 1104, while stretching the second spring 711.

[0047] Through the above, the iron core 11 is placed on the base 6, positioned by inserting the insertion cylinder 701 into the second jack 1103, and at the same time the positioning column 710 is automatically inserted into the positioning groove 1104 for positioning and locking, realizing the automatic connection between the iron core 11 and the base 6 without additional operations, and the installation of the iron core 11 is convenient.

[0048] As Figure 6 and Figure 8 shown, as a specific technical solution, it further includes an exhaust assembly 8; the exhaust assembly 8 includes a sealing plate 801, the sealing plate 801 is fitted and connected with a top hole 604 opened on the top surface of the backing plate 601. A bottom hole 602 is opened on the inner wall of the top of the base 6, and a communication hole 603 is provided for communicating the bottom hole 602 and the top hole 604. A connecting rod 802 is fixed to the bottom surface of the sealing plate 801. The connecting rod 802 passes through the communication hole 603 and the bottom hole 602. A push plate 803 is fixed to the bottom end of the connecting rod 802. The top surface of the push plate 803 is elastically connected with the wall of the bottom hole 602 through a third spring 804, and the third spring 804 is sleeved on the connecting rod 802.

[0049] The exhaust assembly 8 is used for exhausting air inside the cartridge 701; when disconnecting the connection between the iron core 11 and the pad base 6 after they are connected, it can be achieved by simply pushing the push plate 803 upward. After the push plate 803 moves upward, it drives the sealing plate 801 to move upward through the connecting rod 802, separating the sealing plate 801 from the top hole 604 and simultaneously compressing the third spring 804. After the sealing plate 801 is separated from the top hole 604, the top hole 604 loses its blockage, and the cartridge 701 is communicated with the outside atmosphere through the top hole 604, the communication hole 603, and the bottom hole 602, enabling the pressurized gas inside it to be discharged and restoring the atmospheric pressure. Furthermore, the end of the piston 712 connected to the positioning post 710 restores the atmospheric pressure, while the other end of the positioning post 710 is located in the positioning groove 1104, and the positioning groove 1104 is communicated with the outside atmosphere through the ventilation hole 1102. Thus, both ends of the positioning post 710 are in the state of atmospheric pressure. Through the elastic force of the second spring 711, the positioning post 710 and the piston 712 can be reset together. The positioning post 710 is received into the fixed cylinder 709, and the positioning post 710 is separated from the positioning groove 1104, canceling the locking of the iron core 11. Then, the iron core 11 is lifted upward, the iron core 11 is separated from the pad base 6, and the cartridge 701 is separated from the second jack 1103. Through the elastic force of the first spring 705, the movable seat 702 and the movable column 704 can move upward and reset together, and the movable seat 702 extends out from the top of the cartridge 701.

[0050] As Figures 9 - 10 shown, as a specific technical solution, a connection assembly 10 is installed at the bottom of the connection seat 5; a first jack 101 is provided on the support frame 1, and a cylinder 9 is fixedly communicated with the bottom of the first jack 101, and the connection assembly 10 is inserted into the cylinder 9.

[0051] As Figure 10 shown, as a specific technical solution, the connection assembly 10 includes a column body 1001; the column body 1001 is connected to the inside of the cylinder 9 with a clearance fit, guide grooves 1003 are provided on both sides of the column body 1001, insertion blocks 1002 are slidably connected to the guide grooves 1003, a fourth spring 1004 is arranged in the guide grooves 1003, and the insertion blocks 1002 are elastically connected to the walls of the guide grooves 1003 through the fourth spring 1004. Slots 901 are provided on both inner walls of the cylinder 9, and the insertion blocks 1002 are inserted into the slots 901.

[0052] As Figure 10 shown, as a specific technical solution, a pressure-receiving inclined surface is provided at the bottom of one side of the insertion block 1002, and extrusion inclined surfaces 102 adapted to the pressure-receiving inclined surface are provided on both sides of the top end of the first jack 101.

[0053] As Figure 10As shown, as a specific technical solution, a chute 1006 is provided inside the column 1001. The chute 1006 is an inverted L shape, and one end of the chute 1006 communicates with the guide groove 1003. The other end of the chute 1006 is located at the bottom end of the column 1001. The bent portion of the chute 1006 is arc-shaped. A pull rope 1005 is slidably connected inside the chute 1006. One end of the pull rope 1005 is fixedly connected to the plug 1002, and a pull block 1007 is fixed at the other end of the pull rope 1005, and the pull block 1007 is located at the bottom of the column 1001.

[0054] While the iron core 11 is connected to the cushion seat 6, the connecting seat 5 is connected to the cylinder 9 through the connecting assembly 10. Through this design, the effect of connection and fixation is improved. The specific operation is as follows: The column 1001 is passed through the first jack 101, and the column 1001 is inserted into the cylinder 9. During the insertion process, the compression inclined surface is pressed by the extrusion inclined surface 102, so that the plug 1002 is received into the guide groove 1003, and at the same time, the fourth spring 1004 is compressed. When the bottom surface of the connecting seat 5 contacts the top surface of the support frame 1 and the column 1001 is completely inserted into the cylinder 9, and at the same time the plug 1002 is aligned with the slot 901, through the elastic force of the fourth spring 1004, the plug 1002 can be pushed into the slot 901 for plugging, realizing the connection between the connecting seat 5 and the support frame 1. And this connection can be realized by inserting the column 1001 into the cylinder 9 without additional operations, and the operation is simple and convenient.

[0055] When disconnecting the connection between the connecting seat 5 and the support frame 1, by pulling the pull block 1007 downward, the pull block 1007 pulls the pull rope 1005, and the pull rope 1005 slides in the chute 1006. At the same time, the pull rope 1005 drives the plug 1002 to leave the slot 901 and compresses the fourth spring 1004 to complete the release of the positioning. Keeping the state of the pull block 1007, then by lifting the connecting seat 5 upward, the column 1001 can be pulled out of the cylinder 9. Then release the pull block 1007, and through the elastic force of the fourth spring 1004, the plug 1002, the pull rope 1005 and the pull block 1007 can be reset.
