Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: a base for installing a mutual inductor guide rail, comprising a guide rail body 1, both sides of the bottom end of the guide rail body 1 are fixedly connected with mounting plates, the surface of the mounting plate is provided with mounting holes, a base body 2 is arranged at the top of the guide rail body, a slide groove 3 is arranged at a position corresponding to the guide rail surface on the lower surface of the base body 2, the inner cavity of the slide groove 3 is slidably connected with the surface of the guide rail body, a moving groove 4 is arranged on the upper surface of the base body 2, the inner cavity of the moving groove 4 is provided with a disassembly structure 5 convenient for disassembly and assembly with the mutual inductor, a mutual inductor body 6 is arranged at the top of the base body 2, and an elastic structure 7 is arranged at the bottom end of the base body 2 for positioning the position of the base body 2 after being connected to the guide rail, and one end of the elastic structure 7 passes through and extends to the inner cavity of the slide groove 3;

[0028] During installation, place the transformer body 6 on the base body 2, rotate the disassembly structure 5 to fix the transformer body 6, then combine the base body 2 with the track body, slide on the surface of the guide rail through the slide groove 3, and finally position the combined position of the base body 2 and the track body through the elastic structure 7. When disassembling, pull the elastic structure 7 to directly remove the base body 2 from the track body, thereby facilitating the disassembly and assembly work between the transformer and the guide rail, and improving the work efficiency of the disassembly and assembly work between the transformer and the guide rail.

[0029] The disassembly structure 5 includes a bidirectional screw 51, which is rotatably connected to the inner cavity of the movable groove 4 through a rotating shaft. One end of the bidirectional screw 51 passes through the movable groove 4 and is fixedly connected with a knob 52. Both ends of the outer surface of the bidirectional screw 51 are connected with movable blocks 53 through threads. The top of the movable block 53 is fixedly connected with a clamping block 54. A clamping groove 55 is provided at a position corresponding to the surface of the mutual inductor. The surface of the clamping block 54 is engaged with the inner cavity of the clamping groove 55. The bidirectional screw 51 is rotated by rotating the knob 52. The bidirectional screw 51 drives the movable blocks 53 at both ends to move through the threaded connection, so that the movable block 53 drives the clamping block 54 to move. The clamping block 54 is inserted into the inner cavity of the clamping groove 55 to position the mutual inductor body 6. The clamping block 54 moves out of the inner cavity of the clamping groove 55 to release the mutual inductor body 6, and the mutual inductor body 6 and the base body 2 can be disassembled at the same time.

[0030] The shape of the card block 54 is L-shaped, and there are two groups of card blocks 54. Through the setting of the card block 54, the card block 54 and the card slot 55 cooperate to fix the bottom end of the transformer body 6, thereby improving the stability of the card block 54 and the card slot 55 after fixing the transformer body 6.

[0031] A through hole is provided on the surface of the moving block 53, and a sliding limit rod 8 is inserted into the inner cavity of the through hole of the moving block 53. Both ends of the limit rod 8 are fixedly connected to the inner cavity of the moving groove 4. Two groups of limit rods 8 are provided. Through the setting of the limit rods 8, the bidirectional screw 51 is prevented from driving the moving block 53 to flip, so that the moving block 53 can only move up and down on the surface of the bidirectional screw 51, thereby improving the stability of the moving block 53 when moving in the moving groove 4.

[0032] The outer surface of the knob 52 is provided with anti-slip bumps 9, which are spherical in shape. There are several groups of anti-slip bumps 9, which are distributed around the center of the circle on the outer surface of the knob 52. By setting the anti-slip bumps 9, the friction between the knob 52 and the staff's hand is increased, making it convenient for the staff to twist the knob.

[0033] The elastic structure 7 includes a fixing frame 71, which is fixedly connected to the outer wall of the base body 2. A through hole is opened at the center of the fixing frame 71. A movable column 72 is inserted into the inner cavity of the through hole of the fixing frame 71. One end of the movable column 72 is fixedly connected to a positioning block 73. A notch is opened at a position corresponding to the surface of the base body 2 on the surface of the positioning block 73. The notch of the base body 2 extends to the inner cavity of the slide groove 3. The other end of the movable column 72 is fixedly connected to a limited block 74. A spring 75 is sleeved on the outer surface of the movable column 72. The spring 75 is located between the positioning block 73 and the fixing frame 71. When the limit block 74 is pulled through The movable column 72 drives the positioning block 73 to move, so that the positioning block 73 squeezes the spring 75. After the base body 2 and the track body are combined, the limit block 74 is released to allow the spring 75 to rebound and provide a driving force to drive the positioning block 73 to move to the inner cavity of the slide groove 3, so that the surface of the positioning block 73 fits with the bottom end of the guide rail body 1, and the position after the base body 2 and the track body are combined is positioned to achieve rapid installation between the base body 2 and the track body. When the positioning block 73 moves into the inner cavity of the slot of the base body 2, the track body is released to achieve rapid disassembly and assembly between the base body 2 and the track body.

[0034] There are two groups of fixing frames 71, which are symmetrically distributed at both ends of the base body 2. Through the arrangement of the two groups of fixing frames 71, the positioning blocks 73 at both ends can support the bottom end of the track body, thereby improving the stability effect after positioning.

[0035] One side of the positioning block 73 is arranged in an oblique surface, and the other end of the positioning block 73 is arranged with a ball 10. Through the shape setting of the positioning block 73, when the base body 2 and the track body are combined, the positioning block 73 can be pressed from top to bottom to move toward the fixing frame 71 to squeeze the spring 75, which facilitates the installation work between the base body 2 and the track body. Through the setting of the ball 10, the base body 2 can be pushed hard to make the base body 2 slide on the surface of the track body.

[0036] The surface of the limit block 74 is fixedly connected with a connecting rod 11, and the shape of the connecting rod 11 is U-shaped. Through the setting of the connecting rod 11, the staff can drive the limit block 74 to move by pulling the connecting rods 11 at both ends, which provides convenience for the disassembly work between the base body 2 and the track body.

[0037] The bottom of the transformer body 6 is fixedly connected with fixing columns 12 all around, and a fixing groove 13 is provided at a position corresponding to the surface of the fixing column 12 and the surface of the base body 2. The surface of the fixing column 12 and the inner cavity of the fixing groove 13 are plugged and engaged. Through the cooperation between the fixing column 12 and the fixing groove 13, when the transformer body 6 is combined with the base body 2, the fixing column 12 is inserted into the inner cavity of the fixing groove 13, so that the transformer body 6 can be preliminarily fixed between the base body 2.

[0038] Specific use: During installation, take the transformer body and drive the fixing column 12 to insert into the inner cavity of the fixing groove 13, then rotate the button block clockwise to drive the bidirectional screw 51 to rotate, and the bidirectional screw 51 drives the moving blocks 53 at both ends to move through the threaded connection, so that the moving block 53 drives the clamping block 54 to move, and the clamping block 54 is inserted into the inner cavity of the clamping groove 55 to position the transformer body 6, and then take the base body 2 and combine it with the track body. The base body 2 can be placed by pressing from top to bottom so that the positioning block 73 can move toward the fixing frame 71 to squeeze the spring 75, and when the positioning block 73 is driven to move, the bottom end of the track body can release the positioning block 73 to make the spring 75 The spring 75 rebounds and pushes the positioning block 73 to move to the bottom end of the track body, fixing the base body 2 on the track body. When disassembling, pull the connecting rods 11 at both ends to drive the limit block 74 to move, so that the limit block 74 drives the positioning block 73 to move to the inner cavity of the slot of the base body 2 through the movable column 72, and the base body 2 can be released. The base body 2 can be directly removed, and the button block can be rotated counterclockwise to drive the card block 54 to move out of the inner cavity of the card slot 55 through the moving block 53, and the transformer body 6 can be removed from the base body 2, thereby facilitating the disassembly and assembly work between the transformer and the guide rail, and improving the work efficiency of the disassembly and assembly work between the transformer and the guide rail.
