Hanging rack for electroplated parts

Abstract

The hanger comprises a body mechanism and a limiting mechanism which is arranged on the outer side of the body mechanism and reduces the falling risk of a workpiece through a closed hook, the limiting mechanism comprises bases which are symmetrically fixed to the outer side of a transverse frame, and due to the influence of gravity, a limiting column can slide and extend by a certain distance in a sleeve column; at the moment, the space above the hook is sealed by the extended limiting column, then the transverse rod is rotated again to reset the transverse rod until the limiting pin at the bottom of the transverse rod is inserted into the limiting groove in the other side of the limiting column again, the position of the extended limiting column is limited, and finally, the lifting hook is held to move the body mechanism carrying the electroplating workpiece to the position above the electroplating bath. When the body mechanism moves, due to the fact that the position above the hook is sealed by the limiting column, the hooked workpiece can not fall off accidentally under the condition that the body mechanism generates swing, and therefore the stability of the body mechanism in the process of hooking the workpiece is guaranteed.

Description

Technical Field

[0001] This utility model belongs to the field of electroplating parts processing technology, and specifically relates to a hanger for electroplating parts. Background Technology

[0002] Electroplating hangers, also known as electroplating fixtures or electroplating clamps, are tools used to suspend and fix workpieces to be plated during the electroplating process. The design and material selection of the hangers depend on the requirements of the electroplating process, the shape and size of the workpiece, and the layout of the electroplating tank.

[0003] Existing hangers for electroplated parts typically involve hooking the workpiece with hooks and then moving it above the electroplating tank for placement. However, during the movement, because the hooks lack a limiting mechanism, if the movement is too large and the hanger shakes significantly, the hooked workpiece is very likely to fall off, which is quite inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a hanger for electroplated parts. This solves the problem mentioned in the background art that some existing hangers for electroplated parts generally move the workpiece above the electroplating tank by hooking it with a hook. However, during the movement, due to the lack of a limiting mechanism on the hook, when the movement is too large and the hanger shakes greatly, the hooked workpiece is very likely to fall off, which is quite inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hanger for electroplated parts, comprising a main body and a limiting mechanism disposed on the outside of the main body to reduce the risk of workpiece falling off by closing the hook. The limiting mechanism includes a base fixed to the outside of a crossbar symmetrically arranged, a connecting column fixedly connected to the inside of the base, several rotating blocks symmetrically arranged on the top of the connecting column, a rotating arm rotatably connected to the inside of the rotating block, a crossbar fixedly connected to one end of the rotating arm, several limiting pins symmetrically arranged at the bottom of the crossbar, a limiting post slidably connected to the outside of the limiting pin through a limiting groove, limiting sliders fixedly connected to both sides of the limiting post, a sleeve post slidably connected to the outside of the limiting slider, a connecting post fixedly connected to one side of the sleeve post, the sleeve post having an inclined structure, and the space above the hook is closed by sliding the limiting post from inside the sleeve post to above the hook, thereby reducing the risk of workpiece accidentally falling off.

[0006] Preferably, the main body mechanism includes a main frame, with several crossbars symmetrically arranged on the outer side of the main frame, hooks fixedly connected to both sides of each crossbar, and several hooks symmetrically arranged. A lifting hook is fixedly connected to the top of the main frame.

[0007] Preferably, a contact pad is fixedly connected to one end of the limiting post, and the contact pad is located on one side of the hook.

[0008] Preferably, the limiting posts are fixedly connected by connecting strips, and the connecting strips are located on one side of the sleeve posts.

[0009] Preferably, a handle is fixedly connected to the top of the crossbar, and a rotating arm is fixedly connected to one side of the crossbar.

[0010] Preferably, the adjacent sleeve columns are fixedly connected with reinforcing ribs, and the inner side of the sleeve column is slidably connected with a limit column.

[0011] Preferably, the outer surface of the limiting mechanism is coated with polytetrafluoroethylene.

[0012] Preferably, the top of the base has an arc-shaped structure.

[0013] Compared with the prior art, this utility model provides a hanger for electroplated parts, which has the following advantages:

[0014] 1. This utility model features a limiting post with a sleeve post slidably connected to its outer side. One end of the sleeve post is fixedly connected to a connecting post. A limiting pin is slidably connected to the inner side of the limiting post via symmetrically arranged limiting grooves. The sleeve post has an angled structure. Electroplated parts are hooked sequentially onto the outer side of the hook. Then, by directly holding the handle and rotating the crossbar, the rotation of one end of the rotating arm within the rotating block causes the limiting pin to disengage from the limiting groove within the limiting post. At this point, the position of the limiting post is unrestricted. Due to the characteristics of its angled structure and the influence of gravity, the limiting post will slide and extend a certain distance within the sleeve post. The extended portion... The limiting post closes the space above the hook. Then, the crossbar is rotated again to reset the crossbar so that the limiting pin at the bottom of the crossbar is re-inserted into the limiting groove on the other side of the limiting post, thus defining the position of the extended limiting post. Finally, the hook is held and the main body mechanism carrying the electroplated workpiece is moved above the electroplating tank so that it is submerged in the electroplating solution and the operation begins. During the movement, because the position above the hook is closed by the limiting post, the hooked workpiece will not fall accidentally when the main body mechanism swings, thus ensuring the stability of the main body mechanism during the movement of the hooked workpiece.

[0015] 2. This utility model features a handle with a horizontal bar fixedly connected to the bottom, which allows for easy gripping and rotation by a person.

[0016] 3. By setting reinforcing ribs, and fixing sleeves to both ends of the reinforcing ribs, this utility model can effectively ensure the stability of the sleeves during use.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

Detailed Implementation

[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] Please see Figure 1-4This utility model provides a technical solution: a hanger for electroplated parts, including a main body mechanism 1 and a limiting mechanism 2 disposed on the outside of the main body mechanism 1 to reduce the risk of workpiece falling off through a closed hook. The limiting mechanism 2 includes a base 201 symmetrically arranged on the outside of a crossbeam 102. A connecting column 202 is fixedly connected to the inside of the base 201. Several rotating blocks 203 are symmetrically arranged on the top of the connecting column 202. A rotating arm 204 is rotatably connected to the inside of the rotating block 203. A crossbar 205 is fixedly connected to one end of the rotating arm 204. Several limiting pins 206 are symmetrically arranged at the bottom of the crossbar 205. A limiting column 207 is slidably connected to the outside of the limiting pin 206 through a limiting groove. Limiting sliders 208 are fixedly connected to both sides of the limiting column 207. A sleeve column 209 is slidably connected to the outside of the limiting slider 208. A connecting column 202 is fixedly connected to one side of the sleeve column 209. The column 209 has an inclined structure. By sliding the limiting column 207 from inside the sleeve column 209 to above the hook 103, the space above the hook 103 is closed, reducing the risk of the workpiece falling accidentally. After directly holding the handle 5, the crossbar 205 is rotated. Through the rotation of one end of the rotating arm 204 in the rotating block 203, the limiting pin 206 is disengaged from the limiting groove in the limiting column 207. At this time, the position of the limiting column 207 is not restricted. Due to the characteristics of its inclined structure, the limiting column 207 will slide and extend a certain distance inside the sleeve column 209 under the influence of gravity. At this time, the extended limiting column 207 closes the space above the hook 103. Then, the crossbar 205 is rotated again to reset the crossbar 205 so that the limiting pin 206 at the bottom of the crossbar 205 is reinserted into the limiting groove on the other side of the limiting column 207, thus completing the limitation of the position of the extended limiting column 207.

[0026] In this utility model, preferably, the main body mechanism 1 includes a main frame 101, and a number of cross frames 102 are symmetrically arranged on the outer side of the main frame 101. Hooks 103 are fixedly connected to both sides of the cross frames 102, and a number of hooks 103 are symmetrically arranged. A hook 104 is fixedly connected to the top of the main frame 101. The electroplated parts are hooked onto the outer side of the hooks 103 in sequence. By holding the hooks 104, the main body mechanism 1 carrying the electroplated parts is moved to the top of the electroplating tank, so that it is submerged in the electroplating solution in the tank and the operation begins.

[0027] In this utility model, preferably, a contact pad 3 is fixedly connected to one end of the limiting post 207. The contact pad 3 is located on one side of the hook 103, which can effectively reduce the risk of personnel being scratched by the corners.

[0028] In this utility model, preferably, the limiting posts 207 are fixedly connected with connecting strips 4, and the connecting strips 4 are located on one side of the sleeve post 209, which can effectively ensure the stability of the limiting posts 207 during use.

[0029] In this utility model, preferably, a handle 5 is fixedly connected to the top of the crossbar 205, and a rotating arm 204 is fixedly connected to one side of the crossbar 205, which can effectively facilitate personnel to directly hold and rotate it.

[0030] In this utility model, preferably, the sleeve posts 209 are fixedly connected with reinforcing ribs 6 between adjacent sleeve posts 209, and the inner side of the sleeve posts 209 is slidably connected with limiting posts 207, which can effectively improve the stability of the sleeve posts 209 during use.

[0031] In this invention, preferably, the outer surface of the limiting mechanism 2 is coated with polytetrafluoroethylene, which has excellent chemical stability, heat resistance and non-stick properties, and effectively reduces the occurrence of contact between the metal hanger and the electroplating solution.

[0032] In this invention, preferably, the top of the base 201 has an arc-shaped structure, which effectively reduces the occurrence of scratches and damage during the carrying process.

[0033] The working principle and usage process of this utility model are as follows: During use, the electroplated parts are hooked sequentially onto the outer side of the hook 103. Then, by directly holding the handle 5 and rotating the crossbar 205, the rotation of one end of the rotating arm 204 within the rotating block 203 causes the limiting pin 206 to disengage from the limiting groove within the limiting post 207. At this time, the position of the limiting post 207 is unrestricted. Due to the characteristics of its inclined structure and the influence of gravity, the limiting post 207 will slide and extend a certain distance within the sleeve post 209. The extended limiting post 207 then closes the space above the hook 103. Then, the crossbar 205 is rotated again. The crossbar 205 is reset so that the limiting pin 206 at the bottom of the crossbar 205 is re-inserted into the limiting groove on the other side of the limiting post 207, thus limiting the position of the extended limiting post 207. Finally, the hook 104 is held to move the main body mechanism 1 carrying the electroplated workpiece above the electroplating tank, so that it is submerged in the electroplating solution and the operation begins. During the movement, since the position above the hook 103 is closed by the limiting post 207, the hooked workpiece will not fall off accidentally when the main body mechanism 1 swings, thus ensuring the stability of the main body mechanism 1 during the movement of the hooked workpiece.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
