[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] See Figure 1 , 2 .

[0021] This utility model of a welding and positioning fixture for a medical freezer drawer includes two support frames 2, a support bar 3 disposed between the two support frames 2, a plurality of positioning blocks 4 disposed on the support bar 3, and a plurality of elastic pressure plates 5 respectively disposed on the plurality of positioning blocks 4.

[0022] The drawer panel 101 and the partition 104 can be snapped onto the positioning block 4 and fixed to the positioning block 4 by the elastic pressure plate 5. The L-shaped plate 102 located above can be snapped onto the end of the positioning block 4 that is correspondingly away from the support bar 3 and contact the drawer panel 101 and the partition 104. The connecting plate 103 located above can be placed on the positioning block 4 and contact the drawer panel 101 and the partition 104.

[0023] This utility model first positions the drawer panel 101 and the partition 104 by setting multiple positioning blocks 4 and elastic pressure plates 5 on them, and then sets the L-shaped plate 102 and the connecting plate 103 on the positioning blocks 4 to facilitate positioning and welding, thereby improving welding efficiency.

[0024] Specifically, the elastic pressure plate 5 is set on the side of the positioning block 4;

[0025] Specifically, the positioning block 4 is set perpendicular to the support bar 3, and initially remains horizontal;

[0026] Specifically, during use, the support frame 2 is fixed on the workbench.

[0027] In one embodiment, see Figure 2 It also includes multiple limiting blocks 6 respectively disposed on multiple positioning blocks 4, and the limiting blocks 6 can align the side end faces of the drawer panel 101 and the partition 104 with the side end faces of the positioning blocks 4 corresponding to the side of the support strip 3. This design allows the L-shaped plate 102 to be precisely positioned and placed on the drawer panel 101 and the partition 104 after they are placed, ensuring the positioning accuracy during welding;

[0028] Specifically, the limit block 6 is set on top of the positioning block 4.

[0029] In one embodiment, see Figure 2 The support bar 3 can be rotated with the two support frames 2 to achieve flipping. With this design, after the top connecting plate 103 and L-shaped plate 102 are welded to the drawer panel 101 and partition 104, the new connecting plate 103 and L-shaped plate 102 can be re-assembled and welded by flipping.

[0030] Specifically, the welding of the support bar 3 to the support frame 2 can be achieved by a rotating structure of existing technology, such as a bearing, and can rotate 180 degrees in both directions.

[0031] In one embodiment, see Figure 3 The support bar 3 has multiple fixing holes 7 along its length, and the positioning block 4 can be connected to the fixing holes 7 by screws. This design allows the positioning block 4 to be fixed by screws and fixing holes 7, resulting in a simple structure and convenient operation.

[0032] In one embodiment, see Figure 3 The fixing hole group 7 consists of two oval holes spaced apart along the width direction of the support strip 3, and the oval holes are arranged along the length direction of the support strip 3. This design allows for adjustment of the spacing between the positioning blocks 4, thereby adjusting the spacing of the partitions 104.

[0033] In one embodiment, see Figure 3 The support bar 3 is provided with a through groove 301 along its length, and the positioning block 4 is provided with a protrusion 401 that slides with the through groove 301. With this design, the positioning block 4 can be slid to the fixing hole group 7 through the sliding engagement of the protrusion 401 and the through groove 301, and the pre-positioning is achieved through the through groove 301, which facilitates connection by screws;

[0034] Specifically, the through groove 301 is located between the two oval holes in the same fixing hole group 7.
