Description

Technical Field

[0001] The present application relates to the technical field of electroplating hangers, and in particular to a spring electroplating hanger. Background Art

[0002] At present, in the production and processing of springs, especially in the electroplating process of dense coil springs, the springs need to be fixed by electroplating hangers, and the spring coils need to be stretched apart, and finally put together into an electrolytic tank for electroplating.

[0003] Existing, such as Figure 1 As shown, the hanger generally includes a main frame 1 and a plurality of hooks, the hooks are arranged at the upper and lower ends of the main frame, the hooks include L-shaped parts 2 arranged in pairs and having deformation ability, one end of the spring is clamped to the hook at the upper position, and the other end is clamped to the hook at the lower end position to achieve the stretching and fixing of the spring. When the spring is clamped with the hook, the L-shaped part 2 is pressed, the L-shaped part 2 is deformed and approaches each other, the hook is extended into the spring and the L-shaped part 2 is clamped between two adjacent spring coils to achieve the clamping between the hook and the spring.

[0004] With regard to the above-mentioned related technologies, when both ends of the spring are stretched and fixed, they have a certain length. In particular, when the length of the spring itself is relatively large, due to the limited height of the electrolytic cell, some springs with larger lengths cannot be fully immersed in the electrolytic cell, and a larger electrolytic cell needs to be replaced, resulting in poor applicability. Utility Model Content

[0005] In order to reduce the height space occupied by the spring after being stretched and fixed, without replacing a larger electrolytic cell, the present application provides a spring electroplating hanger.

[0006] The spring electroplating hanger provided in this application adopts the following technical solution:

[0007] A spring electroplating hanger comprises a hanger and a hook, wherein a plurality of cross bars are arranged at intervals at the lower end of the hanger, the hooks are arranged at both ends of the cross bars, each of the cross bars is provided with a positioning rod, the positioning rod has deformation capability and is in an arc shape, one end of the positioning rod is fixed to one end of the cross bar, and the other end is detachably connected to the other end of the cross bar.

[0008] By adopting the above technical solution, the spring is sleeved on the outside of the positioning rod from the detachable end of the positioning rod, and one end of the spring is clamped on the hook close to the fixed end of the positioning rod, then the detachable end of the positioning rod is fixed to the other end of the cross bar, and then the spring is stretched, and the other end of the spring is clamped on the hook at the other end of the cross bar; and the positioning rod can limit the extended shape of the spring, so that the spring is in an arc shape corresponding to the positioning rod after being stretched and fixed, rather than the vertical stretching and fixing device of the prior art, so as to reduce the height space occupied by the spring after being stretched and fixed, and only the hanger needs to be remade, without replacing a larger electrolytic cell.

[0009] Preferably, a sleeve is vertically provided at one end of the cross bar, one end of the positioning rod is inserted into the sleeve, and the other end is welded and fixed to an end of the cross bar away from the sleeve.

[0010] By adopting the above technical solution, since the positioning rod has a certain deformation ability, the end of the positioning rod can be inserted into the sleeve through a certain external force, so that the positioning rod is stuck in the sleeve to achieve a quick and detachable connection between one end of the positioning rod and the cross bar.

[0011] Preferably, the height of the sleeve is adjustable.

[0012] By adopting the above technical solution, since the positioning rod is constantly subjected to external force during use, it may be deformed, causing the position of the detachable end of the positioning rod to change. By adjusting the height position of the sleeve, the end of the positioning rod can be better inserted into the sleeve.

[0013] Preferably, a stud is vertically fixed on the cross bar, an inner wall of the sleeve is provided with an internal threaded portion, and the sleeve is threadedly connected to the stud.

[0015] Preferably, when the detachable end of the positioning rod is located outside the sleeve and is in a natural state, the detachable end of the positioning rod is lower than the upper end of the sleeve and is located at one side of the sleeve.

[0016] By adopting the above technical solution, when the positioning rod leaves the sleeve and is in a natural state, the detachable end of the positioning rod is located on one side of the sleeve, so that the positioning rod can be inserted into the sleeve with slight deformation, and the stability of the positioning rod inserted into the sleeve is guaranteed.

[0017] Preferably, it also includes an adapter sleeve, the outer side of which is provided with an external threaded portion threadably matched with the inner wall of the seal spring, the adapter sleeve is clamped on the hook, and the inner diameter of the adapter sleeve is larger than the outer diameter of the sleeve.

[0018] By adopting the above technical solution, the adapter sleeve can be directly threadedly connected to the inside of the seal ring spring to achieve the fixation of the adapter sleeve and the seal ring spring, and then the adapter sleeve is clamped together through the hook, so that the seal ring spring can be quickly and indirectly fixed to the hook.

[0019] Preferably, the hook includes a pair of hook parts, and hanging holes are provided on opposite sides of the adapter sleeve, and the hook parts are clamped in the hanging holes.

[0020] By adopting the above technical solution, the hook can be clamped in the hanging hole. Since the spring is stretched, the restoring force of the spring will apply an upward component force to the transfer sleeve, thereby realizing the rapid clamping of the transfer sleeve and the hook.

[0021] Preferably, the positioning rod is selected to be a copper bar.

[0022] By adopting the above technical solution, the copper bar has good electrical conductivity and elastic deformation ability, which makes it easy to adjust the detachable end position of the positioning rod.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] (1) By arranging the coordination between the cross bar, the positioning rod and the hook, the fixed spring can extend along the length direction of the positioning rod, thereby reducing the height space occupied by the spring after being stretched and fixed, and there is no need to replace a larger electrolytic cell;

[0025] (2) By providing a sleeve, the detachable end of the positioning rod can be quickly inserted into the sleeve, thereby facilitating a quick and detachable connection between the positioning rod and the cross bar;

[0026] (3) By setting up the adapter, the two ends of the seal ring spring can be quickly and indirectly fixed to the hook. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 2-4 This application is described in further detail.

[0033] The present application embodiment discloses a spring electroplating hanger. Figure 2 and him Figure 3 The electroplating rack includes a rack 3, a plurality of hooks 4 and a plurality of cross bars 6; the rack 3 includes a column 31 and a bottom bar 32, the bottom bar 32 is vertically welded to the bottom of the column 31, the cross bars 6 are fixed to the bottom bar 32 at intervals and in parallel, the cross bars 6 are arranged in the horizontal direction, the hooks 4 are fixed to both ends of the cross bars 6, and the two ends of the spring are respectively clamped to the hooks 4 on both ends of the same cross bar 6.

[0034] Each cross bar 6 is provided with a corresponding positioning rod 5, which has deformation capability and is in an arc shape. One end of the positioning rod 5 is welded and fixed to the upper surface of one end of the cross bar 6, and the other end is detachably connected to the upper surface of the other end of the cross bar 6, and the spring is sleeved on the positioning rod 5. In this embodiment, the positioning rod 5 is selected to be bent and formed by a copper strip material. Under a certain external force, the copper strip is guaranteed to have a certain deformation capability and to ensure that the positioning rod 5 can be adjusted to a certain position; and the copper strip itself has a certain diameter, which ensures that the spring can be shaped along the extension direction of the positioning rod 5 after being sleeved on the positioning rod 5. When the detachable end of the positioning rod 5 is removed from the cross bar 6, the spring can be sleeved on the positioning rod 5, and one end of the spring can be hung on the hook 4 near the welding end of the positioning rod 5, and then the detachable end of the positioning rod 5 is fixed to the cross bar 6, and finally the spring is stretched and the other end of the spring is fixed. Since the positioning rod 5 can shape and position the spring, the spring is shaped along the extension direction of the positioning rod 5, thereby reducing the space occupied by the stretching spring after being fixed to the hanger.

[0035] A sleeve 7 is vertically arranged on the upper surface of one end of the crossbar 6, and the inner diameter of the sleeve 7 is slightly larger than the outer diameter of the positioning rod 5, and one end of the positioning rod 5 is inserted into the sleeve 7. When the detachable end of the positioning rod 5 is located outside the sleeve 7 and in a natural state, the detachable end of the positioning rod 5 is lower than the upper end of the sleeve 7 and is located on one side of the sleeve 7. Therefore, when the end of the positioning rod 5 is manually inserted into the sleeve 7, the reset force of the positioning rod 5 causes the end of the positioning rod 5 to rub against the inner wall of the sleeve 7, so that the positioning rod 5 is stably stuck in the sleeve 7, realizing a quick and detachable connection between one end of the positioning rod 5 and the crossbar 6.

[0036] In some embodiments, the height of the sleeve 7 is adjustable, and by adjusting the height position of the sleeve 7, the end of the positioning rod 5 can be more conveniently inserted into the sleeve 7. Specifically, a stud 8 is vertically fixed on the crossbar 6, and an internal thread portion is processed on the inner wall of the sleeve 7. The sleeve 7 is threadedly connected to the stud 8, and the height position of the sleeve 7 can be quickly adjusted by rotating the sleeve 7.

[0037] In some embodiments, reference Figure 3 and Figure 4 The electroplating hanger also includes an adapter sleeve 9, the outer side of the adapter sleeve 9 is processed with an external threaded portion that is threadedly matched with the inner wall of the seal ring spring, and the adapter sleeve 9 and the spring end are quickly and detachably fixed through a threaded connection; the adapter sleeve 9 is clamped on the hook 4, and the inner diameter of the adapter sleeve 9 is larger than the outer diameter of the sleeve 7, ensuring that the adapter sleeve 9 can pass through the sleeve 7 and be clamped with the hook 4, thereby realizing indirect fixation of the spring and the hook 4.

[0038] The hook 4 includes a pair of fixed hooks 41 at intervals, the hooks 41 are L-shaped, and the hooks 41 are also made of copper, so that the hooks 41 have certain deformation and reset capabilities. The adapter sleeve 9 has hanging holes 10 on opposite sides, and the hooks 41 can be directly and quickly connected to the hanging holes 10. The adapter sleeve 9 can be screwed and fixed to the ends of the dense coil spring. Therefore, when the spring is connected to the hook 4, there is no need to manually pull apart the two adjacent spring coils and then clamp the hook 41 between the spring coils, which facilitates the quick and detachable fixation of the two ends of the spring and the two ends of the cross bar 6.

[0039] The implementation principle of a spring electroplating hanger in an embodiment of the present application is as follows: when in use, the adapter sleeve 9 is screwed onto the two ends of the spring so that the adapter sleeve 9 is fixed to the two ends of the spring; then the spring is sleeved on the positioning rod 5 from the detachable end of the positioning rod 5, and the adapter sleeve 9 at the insertion end of the spring is clamped on the hook 4 close to the fixed end of the positioning rod 5; then the detachable end of the positioning rod 5 is inserted into the sleeve 7, and then the spring is stretched, and the adapter sleeve 9 at the other end of the spring is clamped on the hook 4 at the other end of the cross bar 6; and the positioning rod 5 can limit the extended shape of the spring, so that the spring is the same arc shape as the positioning rod 5 after being stretched and fixed, so as to reduce the height space occupied by the spring after being stretched and fixed, and only the hanger needs to be remade without replacing a larger electrolytic cell.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
