The utility model solves the technical scheme that its technical problem adopts: the Special hanger providing a kind of grommet nut endoporus nickel plating chromium, comprise hanger center pillar and upper arm, described hanger center pillar is vertically arranged, described upper arm has several to be symmetrically between two uniformly distributed along hanger center pillar, the corresponding siphon pipe of every a pair upper arm, this siphon pipe is arranged on hanger center pillar, is in charge of and bundles with corresponding upper arm respectively for siphonal two.
Supplement as one of the present utility model, described siphonal bottom open end is V-shaped.
As preferably, described siphonal two free ends be in charge of flush with the free end of upper arm or stretch out the outside in upper arm.
As preferably, described siphonal two free ends cuttings be in charge of are in the wedge angle of 45 °.
Further, one end of upper arm of every a pair is by rotating shaft and hanger center pillar and around axis of rotation.
Further, described siphonal two iron wires and upper arm be in charge of by being with rubber are connected and fixed.
As preferably, between described upper arm with hanger center pillar, become the angle of 105 °.
Further, the upper end of described hanger center pillar is furnished with hook.
Further, be connected by glue between described siphon pipe with hanger center pillar.

Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
As shown in Figure 1, embodiment of the present utility model relates to a kind of Special hanger of grommet nut endoporus nickel plating chromium, comprise hanger center pillar 1 and upper arm 2, described hanger center pillar 1 is vertically arranged, described upper arm 2 has several to be symmetrically between two uniformly distributed along hanger center pillar 1, the corresponding siphon pipe 3 of every a pair upper arm 2, this siphon pipe 3 is arranged on hanger center pillar 1, is in charge of 7 and bundles with corresponding upper arm 2 respectively for two of siphon pipe 3.
What the utility model mainly utilized is siphon principle, so-called siphon principle, utilize the reactive force phenomenon of liquid level difference exactly, liquid is full of after in an inverted U-shaped tubular structure, one end high for opening is placed in the container of filled with fluid, the liquid in container can continue through siphon pipe and flow out from being opened on lower position.The essence of siphon produces because of gravity and intermolecular cohesion.Siphonage is that between liquid molecule, gravitation and potential energy difference caused, and namely utilizes water colunm pressure poor, flows to lower again after making liter waterborne.Because the mouth of pipe water surface bears different barometric points, water can by pressure large to flow to pressure little, until the barometric point on both sides is equal, the water surface in container becomes identical height, and water will stop flowing.Utilize siphonage the water in container can be extracted out soon.
As shown in Figure 3, what the siphon pipe 3 in this patent adopted is acid and alkali-resistance, high temperature, wear-resisting, the moderate siphon pipe of hardness, can ensure that it uses for a long time, its effect mainly contains two, first effect to be connected in upper arm 2 and when putting in plating tank in nut sleeve, electroplate liquid can enter into two from the bottom open end 8 of siphon pipe 3 and be in charge of 7, and flow into the inside top of nut, and nut tapering upwards also makes air discharge smoothly, the endoporus of whole like this grommet nut can fill electroplate liquid fully, thus obtains complete electrolytic coating.
Another effect of siphon pipe 3 is, when hanger takes out from plating tank, due to siphon principle, be in charge of 7 by the electroplate liquid sucking-off nut inner hole by twice electroplate liquid flows out from bottom open end 8, preventing electroplate liquid from remaining in endoporus also needs artificial removing.
As shown in Figure 2, the bottom open end 8 of described siphon pipe 3 is V-shaped, the V-shaped effect having a water conservancy diversion, when siphon pipe 3 is vertically put in plating tank, the bottom open end 8 of V-arrangement is inner to siphon pipe 3 by electroplate liquid water conservancy diversion, ensure that electroplate liquid can arrive the end being in charge of 7 fast.
As preferably, the free end that two of described siphon pipe 3 are in charge of 7 flushes with the free end of upper arm 2 or stretches out in the outside of upper arm 2, arranges it is be in charge of to ensure the inner tip that 7 can extend into nut like this.
As preferably, the free end cutting that two of described siphon pipe 3 are in charge of 7 is in the wedge angle of 45 °, the free end face of siphon pipe 3 is the level of state in use, siphonal free end face fully and the cap contacts-side-down of nut time, the whole sucking-off of liquid easily will remained in nut, ensures siphon effect.
Further, one end of the upper arm 2 of every a pair is rotated around rotating shaft 4 with hanger center pillar 1 by rotating shaft 4, and be convenient to the rotational angle adjusting upper arm 2, the nut of corresponding different size and type, can certainly electroplate for the endoporus of the part of endoporus that has of long strip shape.
Further; be in charge of 7 and be connected and fixed with upper arm 2 by the iron wire 5 of band rubber for two of described siphon pipe 3; iron wire 5 must there is rubber; and rubber be in charge of 7 and contact; prevent from causing damage to being in charge of 7; also being to protect iron wire 5 not corroded, certainly, also can replacing iron wire 5 with the bundled piece of other firmly anticorrosive.
As preferably, described upper arm 2 and the angle becoming 105 ° between hanger center pillar 1, this angle is downward-sloping when causing nut to hang in upper arm 2, can ensure that nut interior is filled with electroplate liquid all the time like this, certainly this angle is not constant, is can adjust according to practical situation.
As preferably, the upper end of described hanger center pillar 1 is furnished with hook 6, picking and placeing of Convenient dress suspending device, and hook 6 can manually hold, and also can be connected with the machinery of lifting.
Further, described siphon pipe 3 is connected by glue with between hanger center pillar 1, and sliced off by glue when replacing and just can take off, it is firm to facilitate.
Siphon pipe combines with hanger by the utility model patent, utilize siphonal siphon principle ensure that dexterously and grommet nut internal surface covers electrolytic coating completely, solve the medium-term and long-term insoluble technical problem of endoporus plating of grommet nut, greatly ensure the quality of product.
