Description

Technical Field

[0001] This utility model relates to a hanging fixture, specifically, to a multi-layer back-to-back anodizing hanging fixture. Background Technology

[0002] Anodizing technology is a commonly used technique to overcome defects in the surface hardness and wear resistance of aluminum alloys. When anodizing aluminum alloy workpieces, the workpieces need to be suspended on a hanger, which is placed inside the anodizing equipment. The hangers include back-mounted hangers, which are suitable for anodizing equipment where it is inconvenient to suspend the hanger.

[0003] When back-mounted hangers are placed inside anodizing equipment, they are typically supported by foot plates at the bottom. By placing the hanger against the side wall inside the anodizing equipment and positioning the foot plates on the bottom surface, stability is ensured. To guarantee the stability of the hanger, the foot plates on back-mounted hangers usually have a large contact area with the ground. When workers store the hangers in an idle state, the foot plates significantly increase the space occupied by the hanger, causing inconvenience for workers. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer back-to-back anodizing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, one of the objectives of this utility model is to provide a multi-layer back-mounted anodizing fixture, including a hanging plate. Several rotating shafts are vertically arrayed and rotatably arranged on one side of the hanging plate. Several hooks are horizontally arrayed and fixedly connected to the circumferential sidewalls of the rotating shafts. The hooks on each rotating shaft are on the same plane. A rotating mechanism is provided on one side of the hanging plate near the edge of the rotating shafts. This rotating mechanism drives the rotating shafts to rotate synchronously. Two foot plates are symmetrically hinged on one side of the hanging plate near the bottom. The foot plates and rotating shafts are located on the same side of the hanging plate. A connecting rod is fixed to one end of the sidewall between the two foot plates near the hanging plate. The axis of the connecting rod is on the same straight line as the axis of hinge between the foot plates and the hanging plate. A transmission mechanism is provided between the lowest rotating shaft and the connecting rod. When the rotating shaft rotates, the lowest rotating shaft drives the connecting rod to rotate synchronously through the transmission mechanism.

[0006] As a further improvement to this technical solution, a movable groove is provided near the edge of the hanging plate, and the rotating mechanism includes a worm gear that is vertically rotatably disposed inside the movable groove. Several semi-worm gears are vertically arrayed and meshed on one side of the worm gear, and the several semi-worm gears are coaxially fixedly disposed on several rotating shafts.

[0007] As a further improvement to this technical solution, the upper end of the worm gear rotates through the top of the movable groove and extends to the upper side of the hanging plate, and a knob is fixed at the end of the worm gear located on the upper side of the hanging plate.

[0008] As a further improvement to this technical solution, the transmission mechanism includes a transmission rod that is vertically rotatably mounted on one side of the hanging plate. Both ends of the transmission rod are coaxially fixedly connected to a first bevel gear. The upper first bevel gear is meshed with a second bevel gear. The second bevel gear is coaxially fixedly mounted on the lowermost rotating shaft. The lower first bevel gear is meshed with a third bevel gear. The third bevel gear is coaxially fixedly mounted on a connecting rod.

[0009] As a further improvement to this technical solution, the hook includes a hook rod fixed on the rotating shaft and a blocking rod fixed at the other end of the hook rod. The hook rod and the blocking rod form an L-shape, and several hooks on two adjacent connecting rods are staggered. When the foot plate rotates to a state perpendicular to the hanging plate, the hook rod is perpendicular to the hanging plate.

[0010] As a further improvement to this technical solution, the hinge of the foot plate and the hanging plate is located near the bottom corner of the hanging plate. When the foot plate is rotated to a state perpendicular to the hanging plate, the lower sidewalls of the foot plate and the hanging plate are on the same plane.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This multi-layer back-to-back anodizing fixture, when the worker turns the worm gear to drive several half-worm gears to rotate the corresponding shafts, the lowest shaft drives the connecting rod to rotate in the same direction through the transmission mechanism. This causes the shaft to drive the hook rod of the hook to rotate upward to a state parallel to the hanging plate, and the foot plate to rotate to a position parallel to the hanging plate as well. This reduces the space occupied by the fixture, makes it convenient for workers to stack several fixtures, and improves the space utilization of the fixture storage space.

[0024] 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.

[0025] Example 1

[0026] Please see Figures 1-5 As shown, one of the objectives of this embodiment is to provide a multi-layer back-to-back anodizing fixture, including a hanging plate 1. Several rotating shafts 2 are vertically arranged and rotatably mounted on one side of the hanging plate 1. Several hooks 21 are horizontally arranged and fixedly connected to the circumferential sidewalls of the rotating shafts 2. Each hook 21 includes a hook rod fixed to the rotating shaft 2 and a blocking rod fixed to the other end of the hook rod. The hook rod and the blocking rod form an L-shape. Several hooks 21 on adjacent rotating shafts 2 are staggered, which increases the length of the workpiece to be placed, allowing workers to suspend longer workpieces on the hooks 21. After the worker suspends the workpiece on the hook rod of the hook 21… The blocking rod of hook 21 restricts the lateral movement of the workpiece, thereby ensuring the stability of the workpiece suspended on hook 21. When using this hanger, several workpieces are first suspended on several hooks 21 respectively. Then, the side of the hanging plate 1 away from the rotating shaft 2 is placed against the side wall inside the anodizing equipment, and the lower side wall of the hanging plate 1 is in contact with the bottom surface inside the anodizing equipment, so that several workpieces are immersed in the electrolyte inside the anodizing equipment. A through groove is opened on the hanging plate 1, so that the electrolyte can come into contact with the side of the workpiece close to the inside of the anodizing equipment through the through groove, thereby increasing the contact area between the workpiece and the electrolyte and improving the anodizing effect of the anodizing equipment on the workpiece.

[0027] To enhance the stability of the hanging plate 1 inside the anodizing equipment, existing technology fixes foot plates 3 to the bottom of the scraper. However, when workers store the hanging plate in its idle state, the foot plates 3 perpendicular to the hanging plate 1 and the hook rod significantly increase the space occupied by the hanging plate, causing inconvenience to workers. To solve this problem, the improvement of this solution is that two foot plates 3 are symmetrically hinged on one side of the hanging plate 1 near the bottom. The foot plates 3 and the pivot 2 are located on the same side of the hanging plate 1, and the hinge point between the foot plates 3 and the hanging plate 1 is located near the bottom of the hanging plate 1. Near the bottom corner, a rotating mechanism 4 is installed on the side of the hanging plate 1 near the edge of the rotating shaft 2. The rotating mechanism 4 is used to drive several rotating shafts 2 to rotate synchronously. At the same time, a connecting rod 31 is fixed on the side wall between the two foot plates 3 near the end of the hanging plate 1. The axis of the connecting rod 31 is on the same straight line as the axis of hinge between the foot plate 3 and the hanging plate 1. A transmission mechanism 5 is installed between the bottommost rotating shaft 2 and the connecting rod 31. When the rotating shaft 2 rotates, the bottommost rotating shaft 2 drives the connecting rod 31 to rotate synchronously through the transmission mechanism 5.

[0028] When the hanger is in use, the drive mechanism 4 drives the rotating shaft 2 to rotate. The rotating shaft 2 causes the hook 21 to flip downwards. At this time, the hook 21 gradually moves closer to the horizontal direction. The rotating shaft 2 at the bottom drives the transmission mechanism 5 to rotate, which in turn drives the connecting rod 31 to rotate. The rotating connecting rod 31 causes the two foot plates 3 to flip downwards. When the foot plates 3 rotate to a state perpendicular to the hanging plate 1, the foot plates 3 and the lower side wall of the hanging plate 1 are on the same plane. At this time, the hook rod of the hook 21 is perpendicular to the hanging plate 1. Then the hanger is placed inside the anodizing equipment. The lower side wall of the foot plates 3 and the hanging plate 1 are in contact with the bottom surface inside the anodizing equipment. The foot plates 3 will restrict the hanging plate 1 from tilting away from the side wall of the anodizing equipment, thereby enhancing the stability of the hanging plate 1 inside the anodizing equipment and preventing the workpiece from falling off the hanger due to tilting. This makes it convenient for workers to perform anodizing treatment on the workpiece.

[0029] When workers need to store the hanging fixtures that are not in use, they use a rotating mechanism 4 to drive several rotating shafts 2 to rotate synchronously. This causes the rotating shafts 2 to rotate the hook rods of the hooks 21 upwards until they are parallel to the hanging plate 1. This also causes the blocking rod to rotate to the side of the hook rod closer to the hanging plate 1, thereby reducing the space occupied by the hanging fixture. At the same time, the rotating shaft 2 at the bottom drives the connecting rod 31 to rotate synchronously through the transmission mechanism 5. This causes the connecting rod 31 to drive the two foot plates 3 to rotate synchronously upwards. When the foot plates 3 rotate to a position parallel to the hanging plate 1, the hook rods of the hooks 21 are parallel to the hanging plate 1. At this time, both the foot plates 3 and the hooks 21 are close to the side wall of the hanging plate 1, thereby reducing the space occupied by the hanging fixtures and making it easier for workers to stack several hanging fixtures for storage, thus improving the space utilization of the hanging fixture storage location.

[0030] The following details the structure of the aforementioned rotating mechanism 4 and transmission mechanism 5. A movable groove 11 is provided on the hanging plate 1 near its edge, and the movable groove 11 penetrates the opposite sidewall of the hanging plate 1. (Refer to...) Figure 4 The rotating mechanism 4 includes a worm gear 41 vertically rotatably disposed inside the movable groove 11. Several semi-worm gears 42 are vertically arrayed and meshed on one side of the worm gear 41. The semi-worm gears 42 are also on the same side of the hanging plate 1 as the rotating shaft 2. The semi-worm gears 42 are coaxially fixed on several rotating shafts 2. The upper end of the worm gear 41 rotates through the top of the movable groove 11 and extends to the upper side of the hanging plate 1. A knob is fixed at the end of the worm gear 41 located on the upper side of the hanging plate 1. When the worker holds the knob and turns the worm gear 41, the meshing transmission between the worm gear 41 and the semi-worm gears 42 causes the semi-worm gears 42 to drive the corresponding rotating shafts 2 to rotate. This causes the several rotating shafts 2 to drive the corresponding hooks 21 to rotate synchronously. As the hooks 21 rotate with the rotating shafts 2, the distance between one end of the hook and the hanging plate 1 can be adjusted, thereby folding and storing the hooks 21 to reduce the space occupied by the hanger.

[0031] The structure of the transmission mechanism 5 is detailed below. The transmission mechanism 5 includes a transmission rod 51 that is vertically rotatably mounted on one side of the hanging plate 1. Both ends of the transmission rod 51 are coaxially fixedly connected to a first bevel gear 52. The upper first bevel gear 52 is meshed with a second bevel gear 53. The second bevel gear 53 is coaxially fixedly mounted on the lower rotating shaft 2. The lower first bevel gear 52 is meshed with a third bevel gear 54. The third bevel gear 54 is coaxially fixedly mounted on the connecting rod 31. When the lower rotating shaft 2 drives the second bevel gear 53 to rotate, the meshing transmission between the second bevel gear 53 and the upper first bevel gear 52 causes the upper first bevel gear 52 to drive the transmission rod 51 and the lower first bevel gear 52 to rotate. The meshing transmission between the lower first bevel gear 52 and the third bevel gear 54 causes the third bevel gear 54 to drive the connecting rod 31 to rotate in the same direction as the rotating shaft 2. This allows the connecting rod 31 to drive the two foot plates 3 to rotate and fold, reducing the space occupied by the hanger.

[0032] In this solution, when the worker turns the worm gear 41 to make several half-worm gears 42 drive the corresponding rotating shaft 2 to rotate, the rotating shaft 2 located at the bottom drives the connecting rod 31 to rotate in the same direction through the transmission mechanism 5. This causes the rotating shaft 2 to drive the hook rod of the hook 21 to rotate upward to a state parallel to the hanging plate 1, and also causes the foot plate 3 to rotate to a position parallel to the hanging plate 1. This reduces the space occupied by the hanging fixture, makes it convenient for workers to stack several hanging fixtures, and improves the space utilization rate of the hanging fixture storage location.
