[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-3A horizontal super-long rod electroplating hard chrome conductive rod cooling circulation device is shown, comprising a conductive rod body 1, an inner tube 2, a rotary joint 3, a cooling pump 4 and a liquid storage tank 5. The conductive rod body 1 is a horizontally mounted cylindrical rod body, a cooling channel extending along the axis is provided in the conductive rod body 1, and plugs are respectively installed at both ends of the cooling channel, so as to form a closed cooling chamber 11 in the conductive rod body 1.

[0021] like Figure 3 As shown, two bearing seats 13 are installed on the left half of the conductive rod body 1, and a driving wheel 12 is installed on the left end of the conductive rod body 1. The external driving mechanism drives the conductive rod body 1 to rotate around the bearing shaft 13 through the driving wheel 12. The driving wheel 12 can be a sprocket, a pulley or a gear. A lifting lug 15 is installed on the bearing seat 13, so that the conductive rod body 1 can be hoisted or disassembled.

[0022] A conductive sleeve 14 is installed on the conductive rod body 1, and the conductive sleeve 14 is installed between the two bearing seats 13. The brush abuts against the conductive rod body 1 through the conductive sleeve 14 to realize the power supply of the conductive rod body 1. The extra-long rod is installed on the right end of the conductive rod body 1 through a flange. A water baffle 16 is installed on the right end of the conductive rod body 1 to prevent the electroplating liquid from splashing onto the power-connected part of the conductive rod body 1.

[0023] like Figure 1 , Figure 2 As shown, a rotary joint 3 is installed at the left end of the conductive rod body 1. The rotary joint 3 is a dual-channel 360° rotary joint, which does not affect the rotation of the conductive rod body 1 and can pass water, oil, and gas. The rotary joint 3 includes a liquid inlet 31, a liquid outlet 32, and a reflux port 33. The liquid inlet 31 and the reflux port 33 are respectively connected to the liquid reservoir 5 through pipes, and a cooling pump 4 is installed on the pipe between the liquid inlet 31 and the liquid reservoir 5.

[0024] The liquid outlet 33 is connected to the cooling chamber 11, and an inner tube 2 is coaxially installed in the liquid outlet 33. The left end of the inner tube 2 is connected to the liquid inlet 31, and the right end of the inner tube 2 extends into the right end of the cooling chamber 11, and a gap is left between the right end of the inner tube 2 and the right end of the cooling chamber 11. The outer diameter of the inner tube 2 is smaller than the inner diameter of the liquid outlet 33, so that a reflux channel is formed between the outer wall of the inner tube 2 and the inner wall of the liquid outlet 33, and the reflux channel is connected to the reflux port 32.

[0025] The working principle of the embodiment of the present application is as follows:

[0026] The cooling pump 4 delivers the coolant in the liquid reservoir 5 into the right end of the cooling chamber 11 through the liquid inlet 31 of the rotary joint 3 and the inner tube 2. The coolant flows back from between the inner tube 2 and the cooling chamber 11 to the left end of the cooling chamber 11, and flows back to the liquid reservoir 5 from the confluence port 33 of the rotary joint 3, thereby cooling the conductive rod body 1. The flow of water inside the conductive rod body 1 can also relatively increase the conductive effect.

[0027] As a preferred embodiment of the present application, a spiral blade (not shown) may be fixed on the outer periphery of the inner tube 2, and the outer diameter of the spiral blade is smaller than the inner diameter of the cooling cavity 11 to avoid interference with the conductive rod body 1. The design of the spiral blade can make the coolant flow out in a spiral shape, increasing the contact time with the inner wall of the cooling cavity 11. On the other hand, it can also increase the rigidity of the inner tube 2 and reduce the radial deformation of the inner tube 2.

[0028] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0029] The coolant is directly transported to the inner end of the cooling cavity through the inner tube, and the coolant flows back between the inner tube and the cooling cavity. There is no need to pre-bury cooling pipes, which simplifies the structure of the conductive rod and reduces production costs. At the same time, the coolant is in full contact with the cooling cavity wall, which improves the cooling efficiency.

[0030] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0031] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
