[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1-5An auxiliary device for welding copper tubes in a condenser includes a support plate 1. One end of the support plate 1 is equipped with a fixing block 3 via an installation mechanism 2. The fixing block 3 can be installed via the installation mechanism 2. When welding copper tubes of different sizes is required, the fixing block 3 can be replaced to easily adapt to welding different copper tubes. One end of the fixing block 3 is fixedly connected to an arc-shaped support block 4. Both ends of the support block 4 are fixedly connected to arc-shaped stabilizing blocks 5. The cooperation of the support block 4 and the two stabilizing blocks 5 can restrict the L-shaped copper tube, facilitating subsequent welding and connection of the L-shaped copper tube with other copper tubes. Extension rods 6 are fixedly connected to the top and bottom of the fixing block 3. An installation plate 7 is fixedly connected to the surface of the extension rods 6. The surface of the installation plate 7 is equipped with an anti-detachment mechanism 8. When welding is required, two vertical copper tubes are inserted into the anti-detachment mechanism 8, so that the vertical copper tubes at both ends of the L-shaped copper tube are restricted, thereby facilitating subsequent welding. When welding condenser copper tubes, if the two ends of an L-shaped condenser copper tube need to be welded to other straight copper tubes, the L-shaped copper tube can first be placed on the support block 4. With the help of two stabilizing blocks 5, the position of the L-shaped copper tube is restricted. Then, two copper tubes are inserted into the two ends of the L-shaped copper tube. The two vertical copper tubes can be fixed by the anti-detachment mechanism 8 on the mounting plate 7. This ensures that all three copper tubes are restricted during the welding process, preventing them from easily shaking and affecting the welding effect. Furthermore, when it is necessary to change the structure on the fixing block 3, the fixing block 3 can be easily replaced through the mounting mechanism 2 to adapt to the welding and fixing requirements of copper tubes of different sizes. During the welding process, the support plate 1 can be fixed to the workbench for use, thereby helping to ensure stability when welding the L-shaped copper tube to the other two vertical copper tubes, thus ensuring the normal progress of the welding and achieving efficient and safe welding.

[0018] Furthermore, the mounting mechanism 2 includes an L-shaped mounting block 201 fixedly connected to the top of the support plate 1. The surface of the mounting block 201 is provided with a mounting groove 202. The fixing block 3 is located inside the mounting groove 202. A screw 203 is threadedly connected to the surface of the mounting block 201. One end of the screw 203 is located inside the fixing block 3. When the fixing block 3 needs to be replaced, the screw 203 can be rotated to disengage from the fixing block 3, thereby allowing the fixing block 3 to disengage from the mounting groove 202 on the mounting block 201 and enabling the fixing block 3 to be replaced. After the replaced fixing block 3 enters the mounting groove 202, the screw 203 is rotated again to re-enter the fixing block 3 and fix it in place, thus facilitating replacement.

[0019] Furthermore, one side of the fixing block 3 is in contact with the inner side of the mounting groove 202. After the fixing block 3 enters the mounting groove 202, it can fit into the interior of the mounting groove 202. After the screw 203 rotates to fix the fixing block 3, the fixing block 3 can be restricted by the interior of the mounting groove 202 to prevent rotation and other situations, thus ensuring the stability of the fixing block 3.

[0020] Furthermore, the anti-detachment mechanism 8 includes an insertion slot 801 on the side of the mounting plate 7. An anti-detachment block 802 is inserted inside the insertion slot 801. Two deformable blocks 803 arranged in a V-shape are fixedly connected to one end of the anti-detachment block 802, and a baffle 804 is fixedly connected to the other end of the anti-detachment block 802. A semi-circular stabilizing ring 805 is fixedly connected to the surface of the baffle 804. When it is necessary to restrict the copper tube, the deformable blocks 803 and the anti-detachment block 802 can be inserted into the insertion slot 801 on the mounting plate 7. During this process, the deformable blocks 803 will deform to pass through the insertion slot 801. After passing through the insertion slot 801, the deformable blocks 803 reset to a V-shape and fit against the mounting plate 7, thereby locking the anti-detachment block 802 so that the anti-detachment block 802 and the baffle 804 will not easily detach from the mounting plate 7. The stabilizing ring 805 can accommodate the copper tube, which is convenient for restricting the copper tube for welding.

[0021] Furthermore, a semi-circular closed ring 806 is rotatably connected to the surface of the stabilizing ring 805. A toggle block 807 is fixedly connected to the surfaces of both the stabilizing ring 805 and the closed ring 806. When it is necessary to restrict the copper tube, the vertical copper tube is first inserted into one end of the L-shaped copper tube. During this process, the copper tube will enter the interior of the stabilizing ring 805. Then, the closed ring 806 is rotated so that the closed ring 806 cooperates with the stabilizing ring 805 to restrict the copper tube. The toggle block 807 can be used to easily apply force to the closed ring 806 to rotate it, so that the closed ring 806 can easily restrict the copper tube.

[0022] Furthermore, two protruding blocks 808 are fixedly connected to one side of the sealing ring 806, and a clamping roller 809 is rotatably connected between the two protruding blocks 808. An L-shaped clamping block 810 is fixedly connected to one side of the stabilizing ring 805. After rotating the sealing ring 806, the clamping roller 809 on the protruding block 808 will rotate into the clamping block 810. The clamping block 810 is made of a deformable material, so that the clamping roller 809 can be clamped by the clamping block 810, which facilitates the sealing ring 806 to cooperate with the stabilizing ring 805 to restrict the copper tube. When it is necessary to release the restriction, it is only necessary to apply a large force to the sealing ring 806 by the actuating block 807, so that the clamping roller 809 drives the clamping block 810 to deform, thereby causing the clamping roller 809 to disengage from the clamping block 810, which facilitates the release of the restriction on the copper tube.

[0023] In summary: When welding the L-shaped copper tube, first insert the fixing block 3 into the mounting groove 202 on the mounting block 201, then rotate the screw 203 on the mounting block 201. The screw 203 rotates into the fixing block 3, fixing the fixing block 3 inside the mounting groove 202. The fixing block 3 fits snugly against the mounting groove 202, preventing the fixing block 3 from rotating and affecting its use. Then, insert the anti-detachment block 802 and the deformation block 803 into the insertion groove 801 on the mounting plate 7, so that the baffle 804 can be fixed on the mounting plate 7, and the stabilizing ring 805 can be fixed on the mounting plate 7 for easy subsequent use. Place the L-shaped copper tube between the support block 4 and the two stabilizing blocks 5, and then insert the two vertical copper tubes into the two ends of the L-shaped copper tube. During the insertion process, the copper tubes will enter the adjacent stabilizing rings 805. Then, by applying force to the actuating block 807, the closing ring 806 rotates, and the clamping roller 809 between the protruding blocks 808 on the closing ring 806 is squeezed into the clamping block 810. The clamping block 810 is made of deformable material, which facilitates the clamping roller 809 to be squeezed in and fixed. Thus, the closing ring 806, together with the stabilizing ring 805, can restrict the copper tube and ensure the stability of the copper tube during welding. After welding, by applying force to the actuating block 807, the clamping roller 809 is separated from the clamping block 810 for replacement of the copper tube. The extension rod 6 can keep the support of the mounting plate 7 away from the welding point, so as not to affect the welding process. With the above structure, when welding L-shaped copper tubes, the copper tube can be easily restricted to ensure the normal progress of welding, and the copper tube can be easily removed and replaced after welding, ensuring that the welding efficiency is not affected.
