DETAILED DESCRIPTION

[0028] 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.

[0029] The utility model provides Figure 1-Figure 5 A clamp for preventing cylindrical batteries from rotating is shown, comprising a tray clamp 1, a battery carrier 2 is clamped inside the upper end of the tray clamp 1, and the batteries are fixed to each other by screws, and the left and right sides of the upper end of the tray clamp 1 are fixedly connected with lifting handles 3, and the two lifting handles 3 are located on the left and right sides of the battery carrier 2, and an elastic anti-rotation guard plate 4 is arranged on the upper end of the battery carrier 2, and an anti-rotation pressure plate 5 is arranged on the upper end of the anti-rotation guard plate 4, and the anti-rotation guard plate 4 and the anti-rotation pressure plate 5 are connected to the lifting handle 3 by screws, and a plurality of circular bars are penetrated upward from the upper end of the battery carrier 2. Cylindrical battery 6, and multiple cylindrical batteries 6 are vertically penetrated through the anti-rotation guard plate 4 and the anti-rotation pressure plate 5, and injection holes 7 are opened inside the central front side of the upper end of multiple cylindrical batteries 6. During the production turnover of cylindrical batteries 6, since the injection holes 7 are located at the front side of the upper end of the cylindrical battery 6 and are in an eccentric position, when multiple cylindrical batteries 6 are injected with liquid at the same time through the injection holes 7, the positions of all the injection holes 7 need to be kept consistent to ensure the continuity and stability of the injection, thereby ensuring the production efficiency and production quality of multiple cylindrical batteries 6.

[0030] At this time, multiple bottom positions can be limited by the battery carrier 2, and the pallet clamp 1 can be picked up and placed on the upper end of the production pallet for fixation through the lifting handles 3 on both sides, and multiple cylindrical batteries 6 can be limited in position by the anti-rotation guard plate 4 to prevent the multiple cylindrical batteries 6 from rotating during the production process, ensuring that the positions of the injection holes 7 opened on the upper ends of the multiple cylindrical batteries 6 remain consistent, thereby ensuring normal production, and the anti-rotation guard plate 4 can be limited by the anti-rotation pressure plate 5 and screws on the upper end to ensure that the positions of the anti-rotation guard plate 4 and the battery carrier 2 remain unchanged.

[0031] Preferably, a plurality of guard plate inner holes 8 are penetrated from top to bottom inside the upper end of the anti-rotation guard plate 4, and a plurality of cylindrical batteries 6 are clamped in the anti-rotation guard plate 4 through the guard plate inner holes 8, and a plurality of pressure plate inner holes 9 are penetrated from top to bottom inside the upper end of the anti-rotation pressure plate 5, and the plurality of pressure plate inner holes 9 correspond to the plurality of guard plate inner holes 8 one by one, and a plurality of cylindrical batteries 6 are penetrated in the anti-rotation pressure plate 5 through the pressure plate inner holes 9, so that the cylindrical batteries 6 can be inserted into the guard plate inner holes 8 through the pressure plate inner holes 9 for limiting the position. Since the radius of the circle where the pressure plate inner holes 9 are located is larger than the radius of the circle where the guard plate inner holes 8 are located, and the anti-rotation guard plate 4 is made of a soft elastic material, the cylindrical batteries 6 can be smoothly inserted into the guard plate inner holes 8 without contacting the inner wall of the pressure plate inner holes 9, so that the cylindrical batteries 6 can be limited in position by the friction between the outer wall and the soft inner wall of the guard plate inner holes 8, which can not only fix the position of the cylindrical batteries 6, but also prevent the outer walls of the cylindrical batteries 6 from being damaged.

[0032] Preferably, a plurality of pressure relief grooves 10 are connected to the outside of the inner hole 8 of the guard plate, and the plurality of pressure relief grooves 10 all penetrate the anti-rotation guard plate 4 up and down, and are rotationally symmetrically arranged with respect to the central axis of the inner hole 8 of the guard plate. In the process of restricting the position of the cylindrical battery 6 through the inner hole 8 of the guard plate, the inner hole 8 of the guard plate can disconnect the connection of the inner wall through the plurality of pressure relief grooves 10 connected to the outside, so that the inner wall of the inner hole 8 of the guard plate can be deformed by expansion and contraction, ensuring that the cylindrical battery 6 can be smoothly inserted into and removed from the inner hole 8 of the guard plate, and at the same time, the tightness between the inner wall of the inner hole 8 of the guard plate and the cylindrical battery 6 can be adjusted through the expansion and contraction deformation of the inner wall of the inner hole 8 of the guard plate.

[0033] Preferably, a plurality of carrier sockets 11 are passed through the upper and lower parts of the battery carrier 2, and the plurality of carrier sockets 11 correspond to the plurality of inner holes 8 of the guard plate one by one, and the lower ends of the plurality of cylindrical batteries 6 are plugged into the upper part of the battery carrier 2 through the carrier sockets 11, the carrier sockets 11 are arranged in a "convex" shape, and the upper opening of the carrier sockets 11 is chamfered, the radius of the circle where the upper opening of the carrier sockets 11 is located is greater than the radius of the circle where the inner holes 8 of the guard plate are located, and an elastic limiting sleeve 12 is clamped inside the lower side of the carrier socket 11, and the lower end of the limiting sleeve 12 is fixedly connected to a limiting ring 13, and the circle of the limiting ring 13 is The outer wall of the column is flush with the cylindrical outer wall of the limiting sleeve 12, and the cylindrical inner wall of the limiting ring 13 is located on the inner side of the cylindrical inner wall of the limiting sleeve 12, so that the lower end of the cylindrical battery 6 can be fixed inside the carrier socket 11 through the limiting sleeve 12, and fixed inside the upper end of the battery carrier 2 through the carrier socket 11, and the lower end of the cylindrical battery 6 can be limited in position by the limiting ring 13, so that the cylindrical battery 6 can be stably fixed inside the upper end of the battery carrier 2 through the limiting sleeve 12, and the fixing height can be limited by the limiting ring 13, ensuring that the height and angle of the injection hole 7 at the upper end of the cylindrical battery 6 can be guaranteed to be consistent.

[0034] Preferably, the cylindrical outer wall and the cylindrical inner wall of the limiting sleeve 12 are both provided with a plurality of vertically upward guide grooves 14, and the limiting sleeve 12 is provided with a plurality of expansion airbags 15, and the plurality of expansion airbags 15 are all located between two adjacent guide grooves 14. In the process of inserting and removing the cylindrical battery 6 into and out of the limiting sleeve 12, the cylindrical battery 6 can be restricted and guided by the vertically upward guide grooves 14 provided inside the inner wall, so as to ensure that the cylindrical battery 6 can be vertically inserted and removed. At the same time, since the hollow expansion airbags 15 are provided between the plurality of guide grooves 14, and the plurality of expansion airbags 15 are provided, the cylindrical battery 6 can be inserted and removed vertically. The inside of the expansion airbag 15 is sealed, and the limiting sleeve 12 is made of elastic and soft material. Therefore, when the cylindrical battery 6 is inserted into the limiting sleeve 12, the cylindrical battery 6 and the multiple expansion airbags 15 will squeeze each other, causing the side of the expansion airbag 15 away from the cylindrical battery 6 to expand outward under the action of the internal air pressure, so that the outer wall of the limiting sleeve 12 will squeeze the inner wall of the vehicle socket 11, and at the same time, the inner wall of the limiting sleeve 12 will squeeze the cylindrical battery 6, thereby further reinforcing the position of the cylindrical battery 6 and ensuring the stability of the position of the cylindrical battery 6.
