Description

Technical Field

[0001] This utility model belongs to the field of electrophoresis hanger technology, and relates to a vehicle frame electrophoresis hanger. Background Technology

[0002] In the bicycle frame manufacturing process, electrophoretic coating is a key process to ensure the frame's rust resistance and extend its service life. During the electrophoresis process, special hangers are needed to suspend the frame stably to ensure that the electrophoretic solution can evenly cover the frame surface. Therefore, electrophoresis hangers are required.

[0003] An electrophoretic coating fixture disclosed in Chinese patent CN220643301U includes a mounting rod, a connecting rod fixedly mounted on the outside of the mounting rod, a connecting hook mounted at both ends of the connecting rod, a through groove on the surface of the connecting hook, an arc-shaped locking rod rotatably mounted inside the through groove, a diagonal rod mounted on one side of the arc-shaped locking rod, an elastic element connecting the diagonal rod and the connecting rod, and an adjustment component for driving the diagonal rod to move slidably mounted on the outside of the mounting rod.

[0004] When using this fixture, the movable plate needs to be pulled down before hanging the workpiece on the connecting hook. Since the movable plate will be reset by the second spring, the movable plate needs to be pulled down continuously during the workpiece hanging process, which reduces work efficiency.

[0005] To address the aforementioned problems, this utility model proposes a vehicle frame electrophoresis hanger. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a vehicle frame electrophoresis hanger.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a fixing frame, and two U-shaped mounting blocks are fixedly connected to both ends of one side of the fixing frame, and arc-shaped hooks are fixedly connected to both bottom surfaces of the opening of the mounting blocks;

[0008] A pressure plate is rotatably provided at the bottom of the mounting block, and an arc-shaped limiting plate is rotatably provided at the top of the mounting block. Rotating components are provided on the side of the two mounting blocks that are close to each other, and the rotating components are in transmission cooperation with the corresponding pressure plate and limiting plate.

[0009] The fixing frame has snap-fit ​​components on one side at both mounting blocks, and the snap-fit ​​components are movably snapped into the corresponding limit plates.

[0010] Furthermore, a third rotating shaft is rotatably inserted through the opening at the top of the mounting block. The third rotating shaft is horizontally arranged, and one end of the limiting plate is fixedly sleeved on the middle of the third rotating shaft.

[0011] Furthermore, torsion springs are fitted at both ends of the third rotating shaft located inside the opening of the mounting block. One end of the torsion spring is fixedly connected to one side of the limiting plate, and the other end of the torsion spring is fixedly connected to the inner wall of the opening of the mounting block.

[0012] Furthermore, a first rotating shaft is rotatably inserted through the opening at the bottom of the mounting block. The first rotating shaft is parallel to the third rotating shaft, and one end of the pressure plate is fixedly sleeved on the middle of the first rotating shaft.

[0013] Furthermore, torsion springs are fitted at both ends of the first rotating shaft located inside the opening of the mounting block. One end of the torsion spring is fixedly connected to one side of the pressure plate, and the other end of the torsion spring is fixedly connected to the inner wall of the opening of the mounting block.

[0014] Furthermore, the rotating assembly includes a second rotating shaft, which is rotatably connected to one side of the middle of the mounting block. The second rotating shaft is located between the first rotating shaft and the third rotating shaft, and is parallel to the first rotating shaft. A second gear is fixedly sleeved on the second rotating shaft.

[0015] One end of the first rotating shaft is fixedly fitted with a first one-way bearing, and a first gear is fixedly fitted on the first one-way bearing. One end of the third rotating shaft is fixedly fitted with a second one-way bearing, and a third gear is fixedly fitted on the second one-way bearing. The second gear meshes with the first gear and the third gear.

[0016] Furthermore, the snap-fit ​​assembly includes a T-shaped snap-fit ​​plate, which is horizontally slidably disposed on one side of the mounting block. Guide rods are fixedly connected to one side of the fixing frame at both mounting blocks, and the bottom of one end of the snap-fit ​​plate is horizontally slidably sleeved on the corresponding guide rod.

[0017] Springs are fitted on both guide rods, with one end of the spring fixedly connected to the fixing frame and the other end of the spring fixedly connected to the clamping plate.

[0018] Both of the third rotating shafts have ratchet wheels fixedly fitted at the ends away from the third gear, and the other end of the clamping plate is movably engaged in the groove of the ratchet wheel.

[0019] Furthermore, the top of one end of each of the two card plates is fixedly connected to the same connecting plate, which is slidably disposed between the two mounting blocks.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The frame electrophoresis hanger is equipped with a pressure plate and hooks. When the frame is hung on the hooks, the frame will press down on the pressure plate, causing the pressure plate to rotate downwards. This causes the first shaft and the first gear to rotate, which in turn causes the third gear, the third shaft, and the limiting plate to rotate through the second gear. As a result, the end of the limiting plate automatically rotates between the two hooks to limit the frame. This allows the operator to simply hang the frame, improving work efficiency.

[0022] 2. The frame electrophoresis hanger is equipped with torsion springs on both the first and third rotating shafts. When the connecting plate is pushed to make the end of the clamping plate leave the ratchet, the torsion spring will automatically drive the third rotating shaft to rotate, so that the end of the limiting plate leaves the hook and returns to its original state, making it easy to remove the frame from the hook and convenient to use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A vehicle frame electrophoresis hanger includes a fixing frame 1, with U-shaped mounting blocks 2 fixedly connected to both ends of one side of the fixing frame 1, and arc-shaped hooks 3 fixedly connected to both bottom surfaces of the opening of the mounting blocks 2. The opening on the mounting blocks 2 is located on the side away from the fixing frame 1.

[0030] An arc-shaped limiting plate 13 is rotatably installed at the top of the mounting block 2. The limiting plate 13 and the hook 3 have opposite arc curvature directions. The limiting plate 13 slides with the two hooks 3. The end of the limiting plate 13 can rotate between the two hooks 3, thereby limiting the top of the hook 3.

[0031] A third rotating shaft 12 is rotatably inserted through the opening at the top of the mounting block 2. The third rotating shaft 12 is horizontally positioned. One end of the limiting plate 13 is fixedly sleeved on the middle of the third rotating shaft 12. The third rotating shaft 12 positions one end of the limiting plate 13 within the mounting block 2.

[0032] Both ends of the third rotating shaft 12 inside the opening of the mounting block 2 are fitted with torsion springs. One end of the torsion spring is fixedly connected to one side of the limiting plate 13, and the other end of the torsion spring is fixedly connected to the inner wall of the opening of the mounting block 2. In the initial state, the torsion spring drives the limiting plate 13 to rotate away from the hook 3, so that there is a distance between the end of the limiting plate 13 and the hook 3, so as to facilitate the attachment of the vehicle frame to the hook 3.

[0033] A pressure plate 4 is rotatably installed at the bottom of the mounting block 2.

[0034] A first rotating shaft 5 is rotatably inserted through the opening at the bottom of the mounting block 2. The first rotating shaft 5 is parallel to the third rotating shaft 12. One end of the pressure plate 4 is fixedly sleeved in the middle of the first rotating shaft 5. The first rotating shaft 5 positions one end of the pressure plate 4 inside the mounting block 2.

[0035] Both ends of the first rotating shaft 5 located within the opening of the mounting block 2 are fitted with torsion springs. One end of the torsion spring is fixedly connected to one side of the pressure plate 4, and the other end is fixedly connected to the inner wall of the opening of the mounting block 2. In the initial state, the torsion spring drives one end of the pressure plate 4 to rotate into the hook 3, creating a distance between the pressure plate 4 and the bottom end of the hook 3.

[0036] A rotating assembly is provided on one side of each of the two mounting blocks 2 that are close to each other. The rotating assembly is in transmission cooperation with the corresponding pressure plate 4 and limit plate 13.

[0037] The rotating assembly includes a second rotating shaft 8, which is rotatably connected to one side of the middle of the mounting block 2. The second rotating shaft 8 is located between the first rotating shaft 5 and the third rotating shaft 12, and is parallel to the first rotating shaft 5. A second gear 9 is fixedly sleeved on the second rotating shaft 8.

[0038] One end of the first rotating shaft 5 is fixedly fitted with a first one-way bearing 6, and a first gear 7 is fixedly fitted on the first one-way bearing 6.

[0039] A second one-way bearing 11 is fixedly sleeved on one end of the third rotating shaft 12, and a third gear 10 is fixedly sleeved on the second one-way bearing 11. The second gear 9 meshes with the first gear 7 and the third gear 10. The rotation of the first gear 7 via the second gear 9 drives the third gear 10 to rotate, thereby linking the pressure plate 4 and the limiting plate 13.

[0040] On one side of the fixed frame 1, there are snap-fit ​​components at both mounting blocks 2, and the snap-fit ​​components are movably snapped onto the corresponding limit plates 13.

[0041] The snap-fit ​​assembly includes a T-shaped snap-fit ​​plate 15, which is horizontally slidably disposed on one side of the mounting block 2. Guide rods 16 are fixedly connected to one side of the fixing bracket 1 at both mounting blocks 2, and the bottom of one end of the snap-fit ​​plate 15 is horizontally slidably fitted onto the corresponding guide rod 16. The guide rods 16 position the snap-fit ​​plate 15 on one side of the mounting block 2.

[0042] Both third rotating shafts 12 have ratchet 14 fixedly fitted at their ends away from the third gear 10, and the other end of the clamping plate 15 is movably engaged in the tooth groove of the ratchet 14. The end of the clamping plate 15 that engages in the tooth groove is provided with an inclined surface, so that the clamping plate 15 and the ratchet 14 cooperate to form a ratchet mechanism, thereby restricting the ratchet 14 to rotate only in one direction, so as to facilitate the positioning of the limiting plate 13.

[0043] Springs 17 are fitted onto both guide rods 16. One end of the spring 17 is fixedly connected to the fixing frame 1, and the other end of the spring 17 is fixedly connected to the clamping plate 15. In the initial state, the spring 17 drives the clamping plate 15 to slide towards the ratchet 14, so that the end of the clamping plate 15 abuts against the tooth groove of the ratchet 14.

[0044] The top of one end of each of the two clamping plates 15 is fixedly connected to the same connecting plate 18, which is slidably positioned between the two mounting blocks 2. The connecting plate 18 allows for simultaneous control of the movement of the two clamping plates 15, increasing the ease of operation.

[0045] Working principle:

[0046] When in use, move the frame so that it moves onto hook 3.

[0047] As the frame moves into the hook 3, it first contacts the pressure plate 4, and then presses the pressure plate 4 downward. This causes the pressure plate 4 to rotate downward, and the end of the pressure plate 4 away from the first pivot 5 moves towards the bottom end between the two hooks 3.

[0048] The pressure plate 4 simultaneously drives the first rotating shaft 5 to rotate, at which point the first one-way bearing 6 is locked, causing the first gear 7 to rotate. The torsion spring on the first rotating shaft 5 then twists.

[0049] The first gear 7 drives the second gear 9 to rotate, and the second gear 9 drives the third gear 10 to rotate. At this time, the second one-way bearing 11 is locked, causing the third rotating shaft 12 and the limiting plate 13 to rotate, and the torsion spring on the third rotating shaft 12 to twist. The end of the limiting plate 13 away from the third rotating shaft 12 moves between the two hooks 3.

[0050] At the same time, the third rotating shaft 12 drives the ratchet 14 to rotate. When the ratchet 14 rotates, the teeth on its outer surface will squeeze the clamping plate 15. This causes the clamping plate 15 to slide on one side of the mounting block 2 towards the side closer to the fixing frame 1. At the same time, the clamping plate 15 slides on the guide rod 16 and compresses the spring 17.

[0051] After the teeth of the ratchet 14 pass the end of the retaining plate 15, the spring 17 pushes the retaining plate 15 so that the end of the retaining plate 15 continues to be engaged in the tooth groove of the ratchet 14.

[0052] After the frame is placed on the hook 3, the end of the limiting plate 13 rotates between the two hooks 3, thereby positioning the frame on the hooks 3. The locking plate 15 positions the ratchet 14, thereby positioning the third pivot 12 and the limiting plate 13.

[0053] When the frame needs to be removed, push the connecting plate 18 towards the side closer to the fixed frame 1. The connecting plate 18 drives the clamping plate 15 to move, so that the end of the clamping plate 15 leaves the ratchet 14.

[0054] When the card plate 15 no longer restricts the third rotating shaft 12, the torsion spring on the third rotating shaft 12 will drive the limiting plate 13 to rotate, so that the end of the limiting plate 13 leaves the hook 3 and returns to its original state.

[0055] The limiting plate 13 drives the third rotating shaft 12 to rotate. At this time, the second one-way bearing 11 rotates freely, and the third gear 10 does not rotate. The connecting plate 18 is released, so that the clamping plate 15 continues to limit the ratchet 14.

[0056] When the frame is moved upwards, the torsion spring on the first pivot 5 will drive the pressure plate 4 to rotate, causing the end of the pressure plate 4 away from the first pivot 5 to move into the hook 3.

[0057] The pressure plate 4 drives the first rotating shaft 5 to rotate. At this time, the first one-way bearing 6 rotates freely, and the first gear 7 does not rotate. This restores the pressure plate 4 to its original state for reuse.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
