During the formation production process of batteries, a large amount of gas is generated. If the gas is not discharged in time, it is easy to cause the expansion of the battery case, affecting the appearance and performance of the battery. In order to limit the expansion of the battery case, generally, a restraint tray is used to limit the battery, especially in production processes such as formation and standing, where the restraint tray is needed to limit the expansion of the battery.

[0003] The existing restraint trays have guide rods, and multiple groups of partitions are arranged on the guide rods to achieve the installation restraint effect of the battery. For example, a restraint tray in CN202110159629.0 realizes the installation of batteries with different sizes through a movable restraint space.

[0004] However, currently, on the one hand, the pressure is unknown after locking the guide rod, and it is necessary to measure to avoid damage to the battery caused by excessive pressure; further, it is necessary to adjust the pressure received by the push plate according to the corresponding pressure data provided by the core size. On the other hand, currently, when replacing the size of the existing partition, the whole partition needs to be replaced, so a large number of partitions need to be stored for work, lacking a certain degree of convenience.

Multiple groups of middle linings 8 are provided and are installed side by side between the front end lining 7 and the rear end lining 5. A restraint space 16 is movably arranged between adjacent middle linings 8, and a battery cell is suitable to be placed in the restraint space 16. A locking member is installed on the rear side plate 2, and the locking member is suitable for restricting the distance between the rear side plate 2 and the push plate 3 and detecting the pressure on the push plate 3. The middle lining 8 includes a middle plate 17 and upper and lower distance retaining blocks 9 and 10 located at both ends of the middle plate 17.

The restraint screw 12 is threadedly connected to the screw sleeve 13 and extends to install a connection block, and a pressure sensor 14 is installed in the connection block. Further, a pressure sensor 14 is installed at the end of the restraint screw 12 between the rear side plate 2 and the push plate 3, and the detection end of the pressure sensor 14 is suitable to be arranged towards the push plate 3. A pressure display screen 15 is fixedly installed on the rear side plate 2, and the pressure display screen 15 is signal-connected to the pressure sensor 14.

[0044] The utility model is a novel adjustable restraint tray, which can release the restraint tray by toggling the push plate 3, and the spacing size of the inner lining after restraint is relatively determined by the upper spacing pull block 9 and the lower spacing pull block 10 on the guide rail.
