The two guard frames 2 are designed to be placed in parallel, and the soft-pack lithium battery cells 6 are placed in symmetrically installed clamping blocks 4, wherein the soft-pack lithium battery cells 6 must be placed in a posture where the air bag in the vertical direction is located above the main body; the operating table 1 between the two guard frames 2 is equipped with a plurality of equidistantly distributed through holes 11, and the fixing seats 3 are fixedly installed on the through holes 11 to realize the positioning of the fixing seats 3.

[0042] Specific examples include but are not limited to: Figure 3 As shown, the fixing seat 3 is set to a rectangular structure, the first fixing groove 31 is horizontally opened along the center of the top surface of the fixing seat 3 and passes through the two side surfaces of the fixing seat 3, the first fixing holes 32 of the fixing seat 3 are set on the two side surfaces of the first fixing groove 31, one side is a cylindrical head screw hole, and the other side is a nut fixing hole. When the clamping block 4 is placed in the first fixing groove 31 of the fixing seat 3, the clamping block 4 is set with a first horizontal adjustment hole 41 to match the first fixing hole 32 of the fixing seat 3, and a cylindrical head screw is used to penetrate the fixing seat 3 and the clamping block 4 from one side to the other side at the same time.

[0043] Specific examples include but are not limited to: Figure 4As shown, the clamp block 4 is a groove structure, which has a second fixing groove 42 in the vertical direction, a second adjustment hole 51 is set at the bottom of the extension section, and cooperates with the second fixing hole 43 at the upper end of the clamp block 4, one side of the clamp block 4 is a flat head screw hole, and the other side of the clamp block 4 is a nut fixing hole. When the clamp block 4 is inserted into the second fixing groove 42, a flat head screw is used to penetrate the clamp block 4 and the extension block 5 from one side to the other side, and the nuts and flat head screws are used to connect and fix them; a plurality of connection holes are opened on the side of each clamp block 4 facing away from the soft-pack lithium battery cell 6, and the side connection holes can be connected to the column to realize the connection and fixation of adjacent clamp blocks 4, so that multiple clamp blocks 4 can form rows of overall structures, and the left and right adjacent clamp blocks 4 are parallel to each other, ensuring the convenience of placing the structure.

[0044] Through the above scheme, the guard frame 2 is set to an adjustable structure, and the guard frame 2 is a plastic assembly structure, which can be compatible with the height and thickness of soft-pack lithium batteries 6 of different models. The spacing between the two guard frames 2 is adjustable and can be compatible with the lengths of soft-pack lithium batteries 6 of different models, so that when it comes to different models of soft-pack lithium batteries 6, there is no need to replace parts. Tools such as wrenches can be used to adjust according to the size of the soft-pack lithium batteries 6, effectively ensuring production stability, safety and convenience.

[0045] As an improved specific implementation, each fixing seat 3 is provided with at least one mounting hole 33 along the vertical direction, and the mounting hole 33 is provided on one side or both sides of the first fixing groove 31 , and the mounting hole 33 corresponds to the through hole 11 to fix the entire guard frame 2 .

[0046] Specific examples include but are not limited to: Figure 3 As shown, in this embodiment, two mounting holes 33 are provided on the top surface of the fixing seat 3, and the two mounting holes 33 are distributed on both sides of the first fixing groove 31. At this time, the mounting holes 33 and the first fixing holes 32 are perpendicular to each other, but the two do not intersect, thereby ensuring the firmness of the overall installation and fixation. Of course, a mounting hole 33 on one side of the first fixing groove 31 can also be provided as required, which can save production processes. At this time, the mounting hole 33 is connected to the through hole 11, and the guard frame 2 can be installed in the horizontal circulation operating table 1 or the carrier by screws and nuts.

[0047] Through the above solution, the setting of the mounting holes 33 enables multiple guard frames 2 to cooperate with each other and be installed on any production equipment and transportation circulation carrier corresponding to the requirements, thereby ensuring the adaptability and practicality of the entire structure.

[0048] As an improved specific implementation, the fixing seat 3 on one side of the first fixing groove 31 is provided with a scale 34 for precisely adjusting the clamping block 4 .

[0049] Specific examples include but are not limited to: Figure 2As shown, one clamp block 4 corresponds to one scale 34, and two scales 34 are arranged on the top surfaces on both sides of the mounting hole 33. In this embodiment, the range of the scale 34 is: 0-1 cm, and an arrow is arranged on each clamp block 4, and the tip of the arrow points to the scale 34, so as to cooperate with each other to adjust the indication.

[0050] Through the above scheme, the scale 34 of the fixing seat 3 and the arrow of the clamping block 4 cooperate with each other, and the distance between the two clamping blocks 4 can be accurately adjusted to adapt to the thickness of different types of soft-pack lithium battery cells 6, improve the accuracy of structural positioning, and avoid shaking or tilting of the soft-pack lithium battery cell 6 after placement.

[0051] As an improved specific implementation, both inner walls of the second fixing groove 42 close to the fixing seat 3 are provided with first inclined surfaces 44 facing each other.

[0052] Specific examples include but are not limited to: Figure 1 and Figure 4 As shown, the first inclined surface 44 is arranged on the clamping block 4, and the first inclined surface 44 is arranged obliquely downward along the bottom end of the second fixing groove 42. When the two clamping blocks 4 are arranged facing each other, the two first inclined surfaces 44 extend inwardly. At this time, the two first inclined surfaces 44 can support the bottom of the placed soft-pack lithium battery cell 6 body.

[0053] Through the above solution, the setting of the first inclined surface 44 can enable the soft-pack lithium battery cell 6 to be stably placed on the protective frame 2, thereby ensuring the stability and practicality of the structure.

[0054] As an improved specific implementation, there is a gap 45 between the two facing first inclined surfaces 44 , and the width of the gap 45 is smaller than the width of the second fixing groove 42 .

[0055] Specific examples include but are not limited to: Figure 1 and Figure 4 As shown, the closest ends of the two first inclined surfaces 44 form a gap 45, that is, the interval between the lower ends of the two clamping blocks 4. This gap 45 is smaller than the width of the second fixing groove 42, but it also ensures that there is a certain distance between the two clamping blocks 4. Since the side edge or sealing plate of the soft-pack lithium battery cell 6 should protrude from the side when it is placed, the side edge or sealing edge is inserted into the gap 45 at this time, thereby forming a space for the side edge or sealing edge of the soft-pack lithium battery cell 6;

[0056] Through the above solution, there is a gap 45 between the two clamping blocks 4, which can avoid squeezing damage to the soft-pack lithium battery cell 6 and reduce interference with the soft-pack lithium battery cell 6.

[0057] As an improved specific implementation, a second inclined surface 52 for guiding the placement of the soft-pack lithium battery cell 6 is provided at the top of the extension block 5 .

[0058] Specific examples include but are not limited to: Figure 1 and Figure 5 As shown, the top of each extension block 5 is provided with a second inclined surface 52, and the end of the second inclined surface 52 which is arranged obliquely downward along the top of the extension block 5 has a rounded corner, so as to form a sharp point to scratch the soft-pack lithium battery cell 6. When the two extension blocks 5 face each other, an opening is formed, and the soft-pack lithium battery cell 6 is placed in from this opening, and it can play a preliminary guiding role in the placement of the soft-pack lithium battery cell 6.

[0059] As an improved specific implementation, the first adjustment hole 41 and the second adjustment hole 51 are both arc-shaped slots, the first adjustment hole 41 is arranged horizontally, and the second adjustment hole 51 is arranged vertically. The long diameter of the first adjustment hole 41 is larger than the diameter of the first fixing hole 32. The long diameter of the second adjustment hole 51 is larger than the diameter of the second fixing hole 43. The groove depth of the second fixing groove 42 corresponds to the long diameter of the second adjustment hole 51.

[0060] Specifically, including but not limited to, the arc-shaped slot hole is a combination structural hole of a rectangle and an arc, the left and right horizontal diameters of the first adjustment hole 41 are larger than the first fixing hole 32, and after the clamp block 4 is installed in conjunction with the first fixing hole 32 of the fixing seat 3, the clamp block 4 can move horizontally, which utilizes the deformable property of plastic and adopts the tightening method of the screw to enable the clamp block 4 to move within the first fixing slot 31 of the fixing seat 3; then when the screw is tightened, the clamp block 4 is clamped and locked by the fixing seat 3 to achieve fixed positioning of the clamp block 4; and when the screw is loosened, the clamp block 4 is not clamped and locked by the fixing seat 3, and the clamp block 4 can realize the first adjustment hole 41 movement along the horizontal direction, and the spacing between the symmetrical clamp blocks 4 on both sides can be accurately adjusted according to the thickness of the soft-pack lithium battery cell 6.

[0061] Specifically, including but not limited to, the upper and lower vertical diameters of the second adjustment hole 51 are larger than the second fixing hole 43. At this time, the height of the clamp block 4 is not adjustable, but the extension block 5 is provided with a second adjustment hole 51, and cooperates with the second fixing holes 43 of the clamp block 4 on both sides of the second fixing groove 42, so as to realize the vertical movement of the extension block 5. This also utilizes the deformable characteristics of plastic, and adopts the tightening method of the screw to make the extension block 5 move in the second fixing groove 42 of the clamp block 4; then when the screw is tightened, the extension block 5 is clamped and locked by the protective clamp to realize the fixed positioning of the extension block 5; and when the screw is loosened, the extension block 5 is not clamped and locked by the clamp block 4, so the extension block 5 can realize the second adjustment hole 51 movement along the vertical direction, that is, the height of the extension block 5 can be adjusted by raising and lowering the height of the soft-pack lithium battery cell 6.

[0062] Through the above scheme, the adjustable structure of the guard frame 2 is realized by the mutual cooperation of the fixed seat 3, the clamping block 4 and the extension block 5. At the same time, since the extension block 5 is inserted into the clamping block 4, the groove depth of the second fixed groove 42 corresponds to the long diameter of the second adjustment hole 51, which ensures the moving space of the extension block 5 and is beneficial to the adaptability of the guard frame 2.

[0063] In summary, the utility model can be applied in a variety of situations. For example, according to the needs of production or transportation circulation, two guard frames 2 are used as units, and the fixing seats 3 of the two guard frames 2 are fixedly installed on the horizontal production and transportation circulation platform through the through holes 11. The guard frames 2 installed on the horizontal plane and the soft-pack lithium battery cells 6 are arranged vertically and horizontally with a safe distance, which can be in batches to facilitate production or transportation circulation; and it can also avoid the tipping of the soft-pack lithium battery cells 6 during the production or transportation circulation to the greatest extent, so as to cause unnecessary safety phenomena such as electrolyte leakage and pole ear contact. Of course, it is worth noting that the operating table 1 in the present application is for better understanding and cooperation, but in actual application it can be set according to needs. For example, a carrying table is already provided in the production platform, and multiple guard frames 2 can be directly fixed and installed at this time; there is also a need to place batches of soft-pack lithium battery cells 6 in order to form a tray-type large-scale transportation, and the operating table 1 will be retained at this time.

[0064] Finally, it should be noted that the above is only the preferred implementation of the utility model, and the protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
