[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0030] See also Figure 1-6 The utility model provides a technical solution: an anti-overload clamping stacked magnetic carrier, including a shell 1, a carrier plate 2, a connecting plate 3, a sliding ball 4, a wedge slider 5, a spring 1 6, a slide groove 1 7, a clamping groove 8, a steel plate 9, a clamping block 10, a spring 2 11, a connecting block 12, a clamping block 13, and a slide groove 2 14.

[0031] Example 1

[0032] The stacked magnetic carrier with anti-overload clamping is provided with an anti-overload structure, which can detect whether the plate end of the wedge slider 5 is overloaded while placing materials on the upper surface of the carrier plate 2, specifically:

[0033] The front and rear surfaces of the shell 1 are both provided with grooves, and the carrier plate 2 is slidably installed in the groove on the upper surface of the shell 1. The carrier plate 2 is connected with an anti-overload structure, and the anti-overload structure can judge the overload situation by making the sliding ball 4 push the wedge slider 5 through the weight borne by the carrier plate 2. The anti-overload structure includes a connecting plate 3, and the lower surface of the carrier plate 2 is fixedly connected with the connecting plate 3, and the connecting plate 3 slides through the lower surface of the groove of the shell 1, and sliding balls 4 are installed on both sides of the lower end of the connecting plate 3. The wedge slider 5 is contact-installed below the sliding ball 4, and the wedge slider 5 is slidably embedded in the slide groove 7, and the slide groove 7 is fixedly installed on the bottom surface of the inner wall of the shell 1. A spring is installed between the inner wall surface of the slide groove 7 and the wedge slider 5, and the inclined surface of the wedge slider 5 contacts the spring 6 with the outer surface of the sliding ball 4, and the slide groove 7 corresponds to the grooves set on the front and rear surfaces of the shell 1;

[0034] When the stacked magnetic carrier with anti-overload clamping is used, Figure 3 As shown, firstly, materials are placed on the upper surface of the carrier plate 2 so that the carrier plate 2 bears the weight. Since the connecting plate 3 connected to the lower surface of the carrier plate 2 is slidably connected to the groove on the upper surface of the housing 1, when there is excessive material on the carrier plate 2, the carrier plate 2 will press the connecting plate 3, and then the sliding balls 4 installed at both ends of the connecting plate 3 will move downward, as shown in FIG. Figure 6 As shown in FIG. 1 , the lower surface of the sliding ball 4 is connected to the inclined surface of the wedge slider 5, and the wedge slider 5 is slidably installed in the slide groove 7, so when the sliding ball 4 slides downward, the wedge slider 5 will be pushed away, and one end of the wedge slider 5 will pull the spring 6, so that the spring 6 is stretched, as shown in FIG. Figure 1 As shown, the slots arranged on the outer surface of the housing 1 can observe the moving state of the wedge slider 5. When the wedge slider 5 moves to the outermost edge of the slide groove 7, it indicates that the material on the carrier 2 is overloaded, which is convenient for timely adjustment of the material. After the material is adjusted, the spring 6 connected to one end of the wedge slider 5 will rebound, causing the wedge slider 5 to slide inward, indicating that the amount of material on the carrier 2 is appropriate.

[0035] Example 2

[0036] The stacked magnetic carrier for preventing overload clamping is also provided with a connection structure, which can be overlapped and connected by engaging the connection block 12 with the card slot 8, specifically:

[0037] The shell 1 is connected with a connection structure, and the connection structure can make two shells 1 stacked and connected through a connection block 12. The connection structure includes a card slot 8, and the lower surface of the shell 1 is preset with a card slot 8. The upper surface of the shell 1 is installed with a second slide slot 14, and the second slide slot 14 is slidably connected with the connection block 12. The side surface of the connection block 12 is evenly spaced with card blocks 13. The side surface of the groove of the shell 1 is slidably penetrated by a clamping block 10, and the side surface of the clamping block 10 is provided with a slot, and the slot is engaged with the edge of the steel plate 9. The other side surface of the clamping block 10 is installed with a second spring 11, and the other end of the second spring 11 is fixedly installed on the inner wall side surface of the shell 1. The card blocks 13 evenly spaced on the inner wall side surface of the card slot 8 correspond to the positions of the card blocks 13 set on the connection block 12;

[0038] When magnetic carriers are stacked, Figure 3 As shown, first push the clamping block 10 which is slidably connected to the side surface of the groove of the shell 1 so that the clamping block 10 squeezes the spring 2 11, and then insert the two side edges of the steel plate 9 into the slots of the two clamping blocks 10 respectively, and then clamp the steel plate 9 above the carrier 2 by the clamping block 10, and then dock the card slot 8 on the lower surface of the shell 1 of the second magnetic carrier to be stacked with the connecting block 12 of the first magnetic carrier, so that the second magnetic carrier is stacked and placed above the first magnetic carrier, as shown in FIG. Figure 2 As shown, blocks 13 are provided on the inner wall of the slot 8 and the side surface of the connecting block 12, and the positions of the two groups of blocks 13 correspond to each other. Therefore, after the connecting block 12 is inserted into the slot 8, the connecting block 12 is pushed in the second slide groove 14 to make the inner wall of the slot 8 and the blocks 13 on the side surface of the connecting block 12 engage with each other, and the connection of the two magnetic carriers is completed, which reduces the floor space and is easy to use.

[0039] Working principle: When using the stacked magnetic carrier with anti-overload clamping, an anti-overload structure is provided, which can place materials on the upper surface of the carrier plate 2 while checking whether the plate end is overloaded through the wedge slider 5.
