Description

Technical Field

[0001] This utility model relates to electroplating racks, and more particularly, to a swingable electroplating rack. Background Technology

[0002] Currently, a publicly disclosed Chinese utility model patent, authorization announcement number CN206512296U, discloses an electroplating rack. The main components of this prior art solution include two uprights and a crossbar connecting the bottom ends of these two uprights. Multiple rectangular hanging frames are evenly spaced along the height of the uprights, with the midpoints of their short sides welded and fixed to the uprights. On the lower surface of the two long sides of the rectangular hanging frames, several equally spaced workpiece fixing hooks are evenly fixed. The upper end of the entire electroplating rack also has a large hook for hanging it in the electroplating reaction tank.

[0003] This existing technology utilizes workpiece fixing hooks evenly distributed along the two long sides of a rectangular hanging frame, allowing for convenient individual hanging of a workpiece on each hook. By arranging multiple rectangular hanging frames along the height direction, the rack can simultaneously hang a large number of workpieces, thereby improving the efficiency and convenience of electroplating production.

[0004] However, there are limitations when using the aforementioned existing electroplating racks to electroplat specific products. Figure 1 Taking an L-shaped product 1 as an example, product 1 has two circular holes machined on it, labeled as first circular hole 2 and second circular hole 3, and the opening heights of the two circular holes are different. According to the existing technology, one workpiece fixing hook needs to be passed through the first circular hole 2, and then the other workpiece fixing hook needs to be passed through the second circular hole 3, in order to fix product 1 to the hanger.

[0005] In actual production, to improve efficiency, it is often necessary to electroplate products of different sizes simultaneously. When processing larger L-shaped products of the same type, the distance between the axes of the first and second circular holes will increase accordingly. At this time, since the workpiece fixing hooks on the existing electroplating rack are arranged at equal intervals, the hook spacing cannot be adjusted to adapt to the changes in the hole spacing on products of different sizes. As a result, the existing electroplating rack is difficult to effectively hang larger products and cannot meet the needs of electroplating products of different specifications simultaneously. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a swingable electroplating rack to meet the needs of electroplating products of different specifications at the same time.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a swingable electroplating rack, including hooks, a crossbeam and a vertical rod, wherein multiple hooks are fixed on the crossbeam, and the vertical rod is connected to the side of the crossbeam opposite to the hooks. The vertical rod is connected to a first hook arranged in an L-shape and a second hook arranged in a Z-shape. The first hook includes a first horizontal section and a first vertical section. The two ends of the first horizontal section are fixedly connected to the vertical rod and the first vertical section, respectively. The second hook includes a rotating section, a second horizontal section and a second vertical section. The rotating section is rotatably connected to the vertical rod, and the two ends of the second horizontal section are fixedly connected to the rotating section and the second vertical section, respectively. Both the first vertical section and the second vertical section extend upward. The first vertical section is used to pass through a first circular hole, and the second vertical section is used to pass through a second circular hole.

[0008] To achieve the above technical solution, the first circular hole of the product is fitted into the first vertical section extending upwards from the first hook, and simultaneously, the second circular hole of the product is fitted into the second vertical section extending upwards from the second hook. Since the size of the products to be electroplated may vary, the distance between the first and second circular holes may differ. Since the first hook is fixed to the vertical rod, the operator needs to rotate the rotating section to align the second vertical section and insert it into the second circular hole of the product. The second vertical section of the second hook can be adjusted in angle and horizontal position relative to the fixed position of the vertical rod and the first hook, thereby changing the horizontal distance between the first and second vertical sections to match the actual hole spacing on the product. Once the adjustment is completed and both vertical sections are successfully inserted into the circular holes, the product is securely fixed to the hanger. This overcomes the technical difficulty of existing electroplating hangers, which cannot adapt to products of different specifications, especially those with varying hole spacing, due to the fixed hook spacing. Through simple rotational adjustment, the versatility and adaptability of the hanger for products of different sizes are significantly improved, enabling the electroplating production line to handle products of various specifications more flexibly and efficiently.

[0009] As a preferred embodiment of this utility model, both the first vertical segment and the second vertical segment are provided with protrusions for contacting the end of the product, and the thickness of the protrusions is less than the outer diameter of the first vertical segment and the second vertical segment.

[0010] By implementing the above technical solution, since the thickness of the protrusion is smaller than the outer diameter of the first and second vertical segments, it ensures that the first and second vertical segments can smoothly pass through the first and second circular holes, while also restricting further downward movement of the product in the vertical direction. This significantly reduces the physical contact area of ​​the product, helping to mitigate fixture marks caused by electroplating.

[0011] As a preferred embodiment of this utility model, a protrusion is provided at the end of the rotating segment away from the second horizontal segment. The protrusion is located on the side wall of the rotating segment and is used to abut against the outer wall of the vertical rod.

[0012] By implementing the above technical solution, the contact between the protrusion and the vertical rod can limit the rotation angle range of the rotating section, effectively preventing the second hook from swinging or rotating to an unsuitable position and avoiding interference with the hanger itself or other components.

[0013] In a preferred embodiment of this utility model, the height of the second hook is higher than that of the first hook, and the length of the first vertical segment is equal to the length of the second vertical segment.

[0014] To achieve the above technical solution, the position of the second hook is adjusted upwards, and the length of the first vertical segment is made equal to the length of the second vertical segment, thereby reducing the length of the second vertical segment and lowering the overall weight.

[0015] In a preferred embodiment of this utility model, a plurality of vertical rods are connected to the crossbeam, and the plurality of vertical rods are arranged along the length direction of the crossbeam.

[0016] By implementing the above technical solution, a large number of products to be electroplated can be processed simultaneously in each electroplating cycle, which greatly improves the single-pass processing capacity of the electroplating rack.

[0017] As a preferred embodiment of this utility model, it also includes a hanging rod, the length direction of which is parallel to the length direction of the crossbeam, and an extension section for supporting the hanging rod is connected to the side wall of the vertical rod, the extension section being located at the end of the vertical rod near the crossbeam.

[0018] The above technical solutions greatly improve the compatibility and versatility of workpieces with different shapes and hanging methods, enabling the same hanger to be used for a wider range of products, thus improving flexibility and production efficiency.

[0019] In a preferred embodiment of this utility model, the vertical rod is slidably connected to the horizontal beam along the length direction of the horizontal beam via a sliding sleeve, the sliding sleeve is fixedly connected to the vertical rod, and the sliding sleeve is positioned on the horizontal beam by a limiting structure.

[0020] To achieve the above technical solution, the lateral spacing between adjacent vertical bars can be flexibly adjusted according to the width of the products to be electroplated or the required arrangement. This ensures sufficient space between multiple products for the flow of electroplating solution and current distribution, preventing collisions or obstruction, thereby maximizing the utilization of the beam length and the volume of the electroplating tank and increasing the number of products electroplated in a single batch.

[0021] As a preferred embodiment of this utility model, the limiting structure includes a positioning hole, a mounting hole, and a pin. The plurality of positioning holes are opened on the outer wall of the crossbeam and arranged along the length direction of the crossbeam. The mounting hole is opened on the sliding sleeve. The pin is slidably connected in the mounting hole and is used to pass through the positioning hole.

[0022] To achieve the above technical solution, the vertical rod can be locked in the length direction of the horizontal beam by passing the pin through the mounting hole on the sliding sleeve and inserting it into the preset positioning hole on the crossbeam, effectively preventing the vertical rod from sliding accidentally during the electroplating process.

[0023] As a preferred embodiment of this utility model, a first leakage hole is provided on the bottom wall of the positioning hole, the diameter of the first leakage hole is smaller than the diameter of the positioning hole, and a second leakage hole is provided on the sliding sleeve for communicating with the first leakage hole.

[0024] By implementing the above technical solution, when the electroplating rack is removed from the electroplating tank, the electroplating solution remaining around the positioning holes, mounting holes, and pins can be smoothly drained through the first and second drainage holes. This significantly improves drainage performance, thereby reducing the carryover of electroplating solution, saving costs, and helping to delay the problem of pin jamming caused by corrosion or deposits.

[0025] As a preferred embodiment of this utility model, a connecting groove is provided at one end of the pin near the positioning hole, a slot is provided on the inner wall of the connecting groove, a spring piece is fixedly connected to the inner wall of the positioning hole, and the end of the spring piece away from the inner wall of the positioning hole is used to be embedded in the slot.

[0026] The above technical solution can reliably fix the pin in the positioning hole, effectively preventing the pin from accidentally coming out due to vibration or impact during the movement of the bracket, hoisting, or violent shaking of the electroplating solution. Attached Figure Description

[0037] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0038] A swingable electroplating rack includes hooks 4, a crossbeam 5, and vertical rods 6. Two hooks 4 are fixed to the crossbeam 5, and the hooks 4 are arranged in a U-shape. The vertical rods 6 are connected to the side of the crossbeam 5 opposite to the hooks 4, and multiple vertical rods 6 are arranged along the length of the crossbeam 5. The crossbeam 5 is horizontal, and the vertical rods 6 are vertical. The outer walls of the crossbeam 5 and the vertical rods 6 are coated with insulating paint. The upper ends of the two vertical rods 6 located at both ends of the crossbeam 5 are fixed to the crossbeam 5, and their lower ends are fixedly connected to the crossbeam 7. The lower ends of the remaining vertical rods 6 are slidably connected to the upper surface of the crossbeam 7.

[0039] A sliding sleeve 8 is fixedly connected to the upper end of the vertical rod 6. The sliding sleeve 8 is slidably connected to the horizontal beam 5 along the length direction of the horizontal beam 5. The sliding sleeve 8 is positioned on the horizontal beam 5 by the limiting structure 9.

[0040] The limiting structure 9 includes positioning holes 10, mounting holes 11, and pins 12. Multiple positioning holes 10 are formed on the outer wall of the crossbeam 5 and arranged along the length of the crossbeam 5, with the openings of the positioning holes 10 facing upwards. Mounting holes 11 are formed on the sliding sleeve 8, and the pin 12 is slidably connected to the mounting hole 11 and is used to pass through the positioning hole 10. The diameter of the mounting hole 11 is equal to the diameter of the positioning hole 10.

[0041] A first leakage hole 13 is provided on the bottom wall of the positioning hole 10, and the diameter of the first leakage hole 13 is smaller than the diameter of the positioning hole 10. A second leakage hole 14 is provided on the sliding sleeve 8 for communicating with the first leakage hole 13. The bottom wall of the positioning hole 10 is a conical surface.

[0042] A connecting groove 15 is provided at the end of the pin 12 near the positioning hole 10, and a slot 16 is provided on the inner wall of the connecting groove 15. The slot 16 is elongated. A spring piece 17 is fixedly connected to the inner wall of the positioning hole 10, and the end of the spring piece 17 away from the inner wall of the positioning hole 10 is used to embed into the slot 16. The spring piece 17 is a duplex stainless steel sheet.

[0043] An anti-slip ring 18 is integrally connected to the outer wall of the pin 12.

[0044] An extension section 19 is integrally connected to the side wall of the vertical rod 6, and the extension section 19 is located at the end of the vertical rod 6 near the crossbeam 5. The length direction of the hanging rod 20 is parallel to the length direction of the crossbeam 5, and the hanging rod 20 passes through all the extension sections 19. The two ends of the hanging rod 20 are respectively fixed to the extension sections 19 of the vertical rod 6 at both ends of the crossbeam 5, and the hanging rod 20 is slidably connected to the other three extension sections 19.

[0045] A first hook 21 and a second hook 24 are provided on the vertical rod 6. The first hook 21 is L-shaped and the second hook 24 is Z-shaped. The height of the second hook 24 is higher than that of the first hook 21.

[0046] The first hook 21 includes a first horizontal segment 22 and a first vertical segment 23. The first horizontal segment 22 and the first vertical segment 23 are integrated, and the end of the first horizontal segment 22 away from the first vertical segment 23 is fixed to the outer wall of the vertical rod 6.

[0047] The second hook 24 includes a rotating section 25, a second horizontal section 26, and a second vertical section 27. The rotating section 25, the second horizontal section 26, and the second vertical section 27 are integrated into one piece. The rotating section 25 is rotatably connected to the vertical rod 6. Both the first vertical section 23 and the second vertical section 27 extend upward. The first vertical section 23 is used to pass through the first circular hole 2, and the second vertical section 27 is used to pass through the second circular hole 3.

[0048] The length of the first vertical segment 23 is equal to the length of the second vertical segment 27.

[0049] A protrusion 28 is integrally connected to one end of the rotating section 25 away from the second horizontal section 26. The protrusion 28 is located on the side wall of the rotating section 25 and is used to abut against the outer wall of the vertical rod 6.

[0050] Both the first vertical segment 23 and the second vertical segment 27 are integrally connected with protrusions 29 for contacting the ends of product 1. The protrusions 29 are disc-shaped, and their thickness is less than the outer diameter of the first vertical segment 23 and the second vertical segment 27, while their outer diameter is greater than that of the first vertical segment 23 and the second vertical segment 27. The outer diameters of the first vertical segment 23 and the second vertical segment 27 are equal.

[0051] The electroplating rack is lifted and moved by two U-shaped hooks 4 fixed to the crossbeam 5, and suspended in the electroplating reaction tank. Before hanging product 1, the lateral spacing between the multiple vertical rods 6 arranged along the length of the crossbeam 5 needs to be adjusted according to the width or arrangement requirements of product 1. The pin 12 is pulled out from the mounting hole 11 of the sliding sleeve 8 and the positioning hole 10 of the crossbeam 5, so that the limiting structure 9 is unlocked. At this time, the vertical rod 6 together with the sliding sleeve 8 can slide along the length of the crossbeam 5. After the vertical rod 6 is slid to the predetermined position, the pin 12 is inserted again into a positioning hole 10 on the crossbeam 5 through the mounting hole 11. When the pin 12 is inserted into place, the spring piece 17 on the inner wall of the positioning hole 10 will automatically engage with the slot 16 on the inner wall of the pin 12 connecting groove 15, thereby locking the sliding sleeve 8 and the vertical rod 6 in that lateral position. After the lateral positioning of all the vertical rods 6 is completed, the rack is ready to hang product 1.

[0052] The first circular hole 2 on product 1 is fitted into the first vertical segment 23. At the same time, the second circular hole 3 on product 1 is fitted into the second vertical segment 27. Since the second hook 24 is rotatably connected to the vertical rod 6 through the rotating segment 25, in order to align the second vertical segment 27 with the second circular hole 3 of product 1, the operator rotates the rotating segment 25 of the second hook 24, causing the second horizontal segment 26 and the second vertical segment 27 to swing accordingly until the top of the second vertical segment 27 is aligned with the second circular hole 3 of product 1.

[0053] Once the first circular hole 2 and the second circular hole 3 are successfully fitted into the first vertical segment 23 and the second vertical segment 27, the product 1 will slide downwards along these two vertical segments until the end of the product 1 abuts against the protrusion 29 provided on the first vertical segment 23 and the second vertical segment 27. The protrusion 29 provides support, restricting the further downward movement of the product 1 in the vertical direction, thus completing the vertical positioning of the product 1.

[0054] In addition, the rack is equipped with a hanging rod 20, which provides an additional hanging method. After electroplating is completed, when the rack is removed from the electroplating tank, the electroplating solution remaining in the positioning hole 10 and the sliding sleeve 8 will be discharged through the first drain hole 13 on the bottom wall of the positioning hole 10 and the second drain hole 14 on the sliding sleeve 8.

[0055] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
