Description

Technical Field

[0001] The utility model relates to the technical field of heater processing, in particular to a fin placement tool. Background Art

[0002] In order to improve the utilization rate of the heat generated by combustion, natural gas heaters usually have multiple fins on the heating tube. When the fins are installed, the lack of limit on the fins will cause the intervals between the fins to be unequal, which can easily have an adverse effect on the heating effect. Of course, in order to avoid this problem, the fins are often inserted into a pair of slots first, and then the heating tube is pushed through multiple fins in sequence, and finally the fin installation operation is completed. However, during the operation, due to the lack of support in the middle of the fin, the fin deformation problem is likely to occur, and there is also the inconvenience of the fin insertion operation. Utility Model Content

[0003] The utility model provides a fin placement tool to solve the deficiencies of the prior art, facilitate the insertion of fins, and can stably limit the fins to prevent the fins from being deformed, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

In order to facilitate the insertion operation of the fin, the fin can be inserted into the concave clip fixed on the side plate, one end of the fin is limited by the concave clip, and then the inner push plate is moved to limit the other end of the fin by the concave clip thereon, thereby avoiding the problem of fin deformation when the sleeve is inserted.

[0006] Furthermore, L-shaped support plates are bent at both ends of the lower plate, and the L-shaped support plates support the lower plate.

[0007] Furthermore, a pair of baffles are respectively provided at the upper and lower ends of the concave clamp, and the baffles support the fins to prevent the fins from being deformed during operation.

This operation mode is convenient for the insertion and limiting operation of the fin. The setting of the spring can prevent the excessive movement of the concave clamping piece from causing deformation of the fin.

[0009] Furthermore, a handle bar is provided at the outer end of the rotating plate to facilitate the rotating operation of the rotating plate.
