[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] See Figure 1-3 As shown, one embodiment of this utility model provides an inductor coil lifting device for pulse capacitor testing, comprising:

[0029] The tray 1, the inductor coil 2 is placed on the tray 1, and the bottom of the tray 1 is provided with a through cavity 3;

[0030] The slide 4 is fixed to the upper two sides of the tray 1;

[0031] The protective mechanism 5 is slidably mounted on the slide block 4, and the protective mechanism 5 is used to correspond to both sides of the inductor coil 2;

[0032] A limiting mechanism 6 is disposed on the slide 4, and the limiting mechanism 6 is used to limit the position of the protective mechanism 5.

[0033] A locking mechanism 7 is provided on the protective mechanism 5, and the locking mechanism 7 is used to lock the upper part of the inductor coil 2.

[0034] The aforementioned inductor coil lifting device for pulse capacitor testing, by setting a protective mechanism 5 on the slide 4, with the protective mechanism 5 corresponding to both sides of the inductor coil 2, and the limiting mechanism 6 used to limit the position of the protective mechanism 5, achieves limiting protection on both sides of the inductor coil 2. Then, the locking mechanism 7 is used to lock the upper part of the inductor coil 2, which can achieve multi-directional protection of the inductor coil 2. When the forklift forks enter the recess 3 at the bottom of the pallet 1 for lifting, it reduces the shaking of the inductor coil 2 and greatly reduces the risk of slipping, thus improving safety.

[0035] In one embodiment of the present invention, the protective mechanism 5 includes a protective plate 51, a protective rubber plate 52, and a slider 53. The slider 53 is fixed to the bottom of the protective plate 51 and is slidably connected to the slide block 4. The protective rubber plate 52 is fixed to one side of the protective plate 51 and corresponds to the side wall of the inductor coil 2.

[0036] In this embodiment, the protective plate 51 can be made of rigid materials such as steel plates, which has a certain rigidity to ensure the safety and stability of the protective plate 51 during protection. The protective rubber plate 52 is made of flexible materials such as rubber, which can play a buffering role when it comes into contact with the side wall of the inductor coil 2, avoiding damage to the inductor coil 2.

[0037] Furthermore, a groove can be formed inside the slide block 4, into which the slider 53 can extend and slide in cooperation with the groove. In one embodiment of this utility model, the slider 53 is trapezoidal or rectangular in shape, and the groove needs to be correspondingly set as trapezoidal or rectangular. This increases the contact area between the slider 53 and the groove and ensures that the slider 53 maintains a stable and consistent sliding direction within the groove. In some embodiments, the slider 53 can also be dovetail-shaped or other shapes.

[0038] In one embodiment of this utility model, the heights of both the protective plate 51 and the protective rubber plate 52 are greater than half the height of the inductor coil 2. This allows for a reduction in the height of the protective plate 51 and the protective rubber plate 52 while maintaining the protective effect, thereby reducing costs and making operation more convenient.

[0039] In one embodiment of the present invention, the limiting mechanism 6 includes a limiting plate 61 and at least one limiting groove 62. The limiting grooves 62 are distributed sequentially along the length direction of the slide block 4. The limiting plate 61 can be locked in the limiting groove 62 and protrude from the top of the limiting groove 62.

[0040] In this embodiment, when the slider 53 slides along the slide block 4 to a position close to the side wall of the inductor coil 2, the limiting plate 61 can be engaged into the limiting groove 62 closest to the slider 53, thereby limiting the position of the protective plate 51. It should be noted that the limiting plate 61 and the limiting groove 62 do not completely limit the protective plate 51; an appropriate gap can be left between them and the protective plate 51 to reduce the difficulty of inserting the limiting plate 61 and to maintain an appropriate buffer space between the protective plate 51 and the inductor coil 2.

[0041] In one embodiment of this utility model, a protrusion is provided on the side of the limiting plate 61 corresponding to the limiting groove 62. This reduces the contact area between the limiting plate 61 and the limiting groove 62, facilitating the placement and removal of the limiting plate 61. Preferably, to further facilitate operation, handles 63 are provided on the upper parts of both sides of the limiting plate 61.

[0042] In one embodiment of this utility model, the locking mechanism 7 includes:

[0043] Left latch 71 and right latch 72 are provided on the top of the protective mechanism 5 and are located on the left and right sides of the inductor coil 2, respectively.

[0044] Rope 73, one end of which is connected to the left latch 71, and the other end of which passes over the top of the inductor coil 2 and is fixedly connected to the right latch 72.

[0045] In this embodiment, the upper part of the inductor coil 2 can be fixed by the cooperation of the rope 73, the left buckle 71, and the right buckle 72, thereby reducing the risk of the inductor coil 2 slipping.

[0046] In one embodiment of this utility model, the left latch 71 and the right latch 72 are detachably connected to the top of the protective mechanism 5. Optionally, the left latch 71 and the right latch 72 can be connected to the protective mechanism 5 by means of bolts or other methods.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
