For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0035] Reference example Figures 1 to 5 A European-style box transformer convenient for maintenance, including a box body 1 and a box cover 2 fixed on the box body 1. Inside the box cover 2, a number of equally spaced cylinders 3 are evenly distributed around a dot as the center. A liftable fixing rod 4 is provided inside the cylinder 3. A spring 5 is also provided inside the cylinder 3 and acts on the fixing rod 4 to make the fixing rod 4 move upward. A heat dissipation component 6 is provided at the end of the fixing rod 4. A support frame 7 is also provided inside the box cover 2. The support frame 7 is provided with a screw rod 8, which is threadedly connected to the heat dissipation component 6. By rotating the screw rod 8, the heat dissipation component 6 is driven to move up and down;

[0036] It is worth mentioning that a cavity 31 is provided inside the cylinder 3, and the cavity 31 provides a guiding function for the first retaining ring 41;

[0037] It is worth mentioning that the box cover 2 is provided with a first through hole 21 for accommodating the heat dissipation component 6;

[0038] It is worth mentioning that one end of the fixing rod 4 is provided with a first retaining ring 41 and is slidably arranged inside the cavity 31. The other end of the fixing rod 4 is provided with a second retaining ring 42. A plurality of limiting blocks 43 are evenly distributed on the outer wall of the fixing rod 4 with a dot as the axis and are connected to the first retaining ring 41. The limiting blocks 43 limit the descending distance of the fixing rod 4. At the same time, they play a role in protecting the spring 5. The second retaining ring 42 bears the bearing pressure from the base 61;

[0039] It is worth mentioning that the spring 5 is arranged inside the cavity 31 and abuts against the first retaining ring 41. The elastic force of the spring 5 is transmitted to the fixing rod 4 through the first retaining ring 41, and the fixing rod 4 transmits it to the base 61, so that the threaded hole 621 and the thread groove of the screw rod 8 tightly abut against each other, increasing the friction between the two, and playing a role in fixing the base 61 at the moved position;

[0040] It is worth mentioning that the heat dissipation component 6 includes a base 61 and a fan 62. The base 61 is provided with a threaded hole 621. A plurality of ventilation grooves 612 are evenly distributed on the base 61 with the threaded hole 621 as the axis. Ventilation holes 613 are provided at the bottom of the ventilation grooves 612. The base 61 is provided with a connecting block 614 and is sleeved on the fixing rod 4. The connecting block 614 abuts against the second retaining ring 42. The fan 62 is installed and fixed inside the ventilation grooves 612. The threaded hole 621 is used in cooperation with the screw rod 8, and the connecting block 614 is used in cooperation with the second retaining ring 42;

[0041] It is worth mentioning that the support frame 7 is provided with a second through hole 71. A roller 72 is arranged inside the second through hole 71. Third retaining rings 73 are provided at both ends of the roller 72. A transmission block 721 is provided inside the inner ring of the roller 72. The roller 72 reduces the rotation resistance of the screw rod 8 and reduces the force required for maintenance personnel to rotate. The third retaining rings 73 prevent the roller 72 and the screw rod 8 from falling. The transmission block 721 increases the contact area with the screw rod 8 and increases the transmission efficiency;

[0042] It is worth mentioning that the screw rod 8 is threadedly connected to the threaded hole 621. One end of the screw rod 8 is provided with a cylinder 81. The cylinder 81 is provided with a groove 82 corresponding to the transmission block 721. The cylinder 81 abuts against the third retaining ring 73. The other end of the screw rod 8 is provided with a handwheel 83. The cylinder 81 is used in cooperation with the third retaining ring 73, and the handwheel 83 facilitates the maintenance personnel to rotate the screw rod 8.

[0043] Now, the working principle of the present utility model is described as follows:

[0044] When maintenance is required, rotate the screw rod 8 through the hand wheel 83, and drive the base 61 to move downward. As the base 61 sinks, it drives the fixing rod 4 to move downward together, and stores energy in the spring 5. Until the limiting block 43 abuts against the bottom in the cavity 31, the base 61 can no longer sink. At this time, there is a space convenient for maintenance between the base 61 and the bottom of the first through hole 21 and the box cover 2;

[0045] After the maintenance is completed, rotate the screw rod 8 in the opposite direction through the hand wheel 83, and drive the base 61 to move upward. Since it is in the process of the spring 5 releasing elastic force, when the base 61 is reset, the force required to rotate the hand wheel 83 will be greatly reduced, achieving the effect of labor saving. Until the first retaining ring 41 abuts against the top of the cavity 31, the hand wheel 83 can no longer rotate, and the step of resetting the base 61 is completed.

[0046] Through the above design scheme, the product can achieve the advantages of convenient maintenance and simple operation.

[0047] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
