Description

Technical Field

[0001] The invention relates to the technical field of fixing clips, and in particular to a side fixing clip for an air conditioner heat exchanger. Background Art

[0002] Heat exchangers usually install metal baffles on the side of the fins for protection. Metal rods with hooks at both ends are hooked on the copper tube of the heat exchanger. The middle of the fixing clip is bent to form a broken line protrusion, which presses the baffle against the side of the heat exchanger to improve the stability of the baffle installation. However, it is easy to deform after being under pressure for a long time, resulting in the inability to press the baffle. Therefore, designing a side fixing clip for air conditioner heat exchangers that is not easy to deform and lose pressure has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a side fixing clip for an air conditioner heat exchanger.

[0004] The technical solution of the utility model is a side fixing clamp of an air-conditioning heat exchanger, comprising a pair of copper tube hooks and a fixing piece, one end of the copper tube hook is bent to the side to form a positioning hook, and the other end is provided with a clamping ring, the fixing piece comprises plug-in boards at both ends and an extrusion block in the middle, the plug-in board is connected to the extrusion block to form a U-shaped structure; a plurality of plug-in slots corresponding to the positions are provided on the opposite sides of the plug-in board, the plug-in slots are arranged at intervals along the length direction of the plug-in board, the slot bottoms of the plug-in slots of the same plug-in board are aligned with each other, the clamping ring is sleeved on the outer side of the plug-in board, and one side of the clamping ring is inserted into the plug-in slot.

[0005] After adopting the above structure, the copper tube hook is moved to align on the plug-in plates at both ends of the extrusion block, and the snap ring is correspondingly inserted into the plug-in groove to change the distance between the extrusion block and the snap ring, thereby changing the protrusion degree of the extrusion block. After the positioning hook hooks the copper tube of the heat exchanger, the fixing part can match the position of the metal baffle. When the copper tube hook bends, the protrusion degree of the extrusion block can be increased to ensure that sufficient pressure is applied to the metal baffle, thereby preventing the baffle from loosening and affecting the operation of the heat exchanger.

[0006] As a further improvement of the utility model, the fixing piece is further provided with a closing rod, and the closing rod is connected to the end of the plug board to form a closed loop.

[0007] After adopting the above structure, a closed loop is formed by connecting the end of the plug board through the closing rod to prevent the fixing piece from falling off the copper tube hook, ensuring that the fixing piece can connect a pair of copper tube hooks to generate a pulling force to hook the copper tube of the heat exchanger.

[0008] As a further improvement of the utility model, the slot opening of the plug-in slot is provided with a guiding inclined surface expanding outward.

[0009] After adopting the above structure, when the clamping ring is inserted into the plug-in slot, it contacts the guiding inclined surface of the slot, so that the clamping ring can slide into the plug-in slot along the guiding inclined surface.

[0010] As a further improvement of the utility model, the extrusion block is provided with a convex arc surface.

[0011] After adopting the above structure, the side baffle on the heat exchanger is pressed against by the raised arc surface, thereby avoiding scratching the side baffle.

[0012] As a further improvement of the present invention, the thickness of the clamping ring matches the width of the plug-in slot, and the clamping ring is provided with an abutting plane that fits with the slot wall of the plug-in slot.

[0013] After adopting the above structure, the abutting plane is in contact with the groove wall of the plug-in groove, so as to prevent the clamping ring from swinging in the plug-in groove after being subjected to pressure, thereby improving the stability of the fixing clip.
