Abstract

The utility model relates to an electroplating hanging frame, mainly composed of a hanging frame, a connecting post, a screw cap, etc. The utility model is characterized in that a screw hole is arranged on a fixed base of the hanging frame, the connecting post is screwed in the screw hole, the other end of the connecting post is provided with a fixed rod capable of screwing with the screw cap to fix a circuit board, and a rotating part is arranged on the screw cap. The electroplating hanging frame can be directly and conveniently rotated and fixed by hands and can not cause the teeth of screw threads to pull off due to oversize applied force, and therefore, the utility model has the characteristic of rapidly and conveniently replacing the connecting post and is an electroplating hanging frame having long service life, time saving and low cost.

Description

Electroplating Rack

The utility model is a kind of Electroplating Rack, be meant especially in the hanger permanent seat and be provided with screw, be bolted with joint pin in this screw, joint pin is held in addition and then is provided with fixed link again, but the fixed orifices of this fixed link power circuit board wears, and screw on nut and fix it, so can change joint pin rapidly easily, and easy disassembly and increasing the service life.

When the general circuit plate is electroplated fixedly at present, Electroplating Rack structure such as Fig. 1 of being adopted, shown in 2, the permanent seat 10 that lies in hanger 1 is provided with open-work 11, joint pin 12 1 ends are provided with round bar 13 and establish into open-work 11 internal fixing for packing, joint pin 12 the other ends then are provided with screw thread 14, but the fixed orifices B of power circuit board A penetrates and fixes, again by a nut 15 and screw thread 14 bolts, with fixing circuit board A, and the action of electroplating, these structures only, powerful packing pushes in the open-work 11 because joint pin 12 is the mat instrument, does not align open-work 11 when pushing, then be easy to generate crooked, and joint pin 12 soaks and corrodes through electroplate liquid for a long time, belongs to running stores, therefore takes normal replacing, but joint pin 12 is to push through powerful packing, must beat behind by open-work 11, can take out joint pin 12, therefore change difficult; And open-work 11 is after repeatedly changing joint pin 12, and the aperture of this open-work 11 easily is stretched or damages, can't fixedly connected again post 12; Because open-work 11 positions of hanger 1 are all fixing, can't change arbitrarily, so open-work 11 is in case support is big or damage, then whole group hanger 1 can't use, and cause waste, and it is also more permanent to change time of joint pin 12, cause shortcoming such as lose time.Nut 15 is that the mat pneumatic tool is tightened on the screw thread 14 of joint pin 12 again, because the turning force of pneumatic tool is quite big, and the thread of screw thread 14 is quite meticulous, causes easily when therefore being spirally connected and collapses tooth, more quickens the replacement cycle of joint pin.

The purpose of this utility model provides a kind ofly can change joint pin rapidly easily, and save by ETL estimated time of loading and the Electroplating Rack that reduces cost.

Electroplating Rack of the present utility model mainly is made up of a hanger, a plurality of joint pin and a plurality of nut, and the frame of hanging of this hanger is provided with a plurality of permanent seats on every side, is characterized in that said permanent seat is provided with screw; Said joint pin one end is provided with round bar, and round bar is provided with screw thread, and in the screw that is screwed into permanent seat, the joint pin the other end is provided with fixed link, and this fixed link is provided with screw thread, and the fixed link front end is provided with two side grains; Said nut is provided with turn portion, and nut inside is coated with fixed block again, is provided with inner bolt hole in this fixed block, but this screw swivel nut is on the screw thread of joint pin fixed link.

Relevant the utility model is for reaching above-mentioned application target and function, and the technique means that is adopted is lifted a preferred embodiment now, and conjunction with figs., and details are as follows:

Fig. 1: be known hanger decomposing schematic representation.

Fig. 2: for known hanger uses synoptic diagram.

Fig. 3: be the synoptic diagram of the utility model preferred embodiment hanger.

Fig. 4: be the utility model preferred embodiment three-dimensional exploded view.

Fig. 5: for synoptic diagram is used in the utility model preferred embodiment.

Fig. 6: be the utility model preferred embodiment combination synoptic diagram.

Fig. 7: be the synoptic diagram of finishing of the utility model preferred embodiment hanger.

At first, see also shown in Fig. 3,4, the utility model is mainly by hanger 2, and a plurality of joint pins 3 and a plurality of nut 4 are formed.The frame 20 of hanging of this hanger 2 is provided with four permanent seats 21 on every side, and this permanent seat 21 is provided with screw 22; Said joint pin 3 is to be screwed in the screw 22, and these joint pin 3 one ends are provided with round bar 30, and this round bar 30 is provided with screw thread 31, and joint pin 3 the other ends are provided with fixed link 32 again, and this fixed link 32 is provided with screw thread 33, and fixed link 32 front ends are provided with two side grains 34 again; Said nut 4, spiral shell is located on joint pin 3 fixed links 32, this nut 4 is that ABS (make by vinyl cyanide---divinyl---styrene copolymer material, it has high temperature resistant and characteristic such as acid and alkali-resistance, this nut 4 is provided with turn portion 40, nut is coated with a fixed block 41 when ejection formation, be provided with an inner bolt hole 42 in this fixed block 41.

During use, shown in Fig. 5,6, clamp two side grains 34 of joint pin 3 by throw, the screw thread 31 of joint pin 3 round bars 30 is screwed in the screw 22 of permanent seats 21 and fix, fixed orifices B with circuit card A is arranged on the fixed link 32 of joint pin 3 again, grip the turn portion 40 of nut 4 again with hand, nut 4 is tightened on the fixed link 32 of joint pin 3, thus simple and easy and promptly circuit card A is fixed on and hangs (as shown in Figure 7) on the frame 20; When needing to change as damaging when joint pin 3, as long as the mat throw screws off joint pin 3, the new joint pin 3 that changes the outfit again get final product, and so 22 of screws on the hanger 2 can not collapse tooth and damage, but the repetitiousness use has prolonged work-ing life of hanger 2.

By above explanation as can be known, the utility model has following advantages really:

1. the upper joint pin that can conveniently be spirally connected easily of the screw on the hanging rack fixed seat, when changing joint pin, Tooth damage can not expanded or collapse to screw, can repeatedly use, and reduced the fault of hanger, and then saved into This.

2. nut system is made by the ABS material, can high temperature resistant and acid and alkali-resistance, and nut is provided with turn section, can Fixing to rotate by hand, so the torsion the when application of force is rotated is littler, can not cause the damage of joint pin, and And at any time dismounting can be saved time.

In sum, the utility model can reach the application target and the effect of being expected really, and more known product has practicality and progressive, proposes patent application in accordance with the law, earnestly asks patent early.
