[0003] In the existing copper plating hanger, a circuit board is often fixed on the copper plating hanger manually before copper plating.
[0004] Although the current copper sinking hanger can be clamped and fixed, it requires two people to work together when clamping and fixing large circuit boards because workers cannot hold the circuit boards with one hand. Utility Model Content

[0007] The utility model is further configured to include a frame, wheel rods are arranged on both sides of the frame, a cylinder is installed at one end of the frame, a convex block is fixed at one end of the cylinder, rollers are arranged on both sides of the convex block, and the rollers are slidably connected to the outer surface of the wheel rod.
[0008] The utility model is further configured that a first fixing block is fixed to one end of the convex block, a fixing plate is arranged on the top of the first fixing block, and a plurality of protective shells are arranged on the top of the fixing plate.
[0009] The utility model is further configured as follows: a first slider is fixed inside the protective shell, fixed piles are fixed on both sides of the top of the first slider, a first spring is fixed to one end of the fixed pile, a wedge block is fixed to one end of the first spring, a rubber plate is fixed to one end of the wedge block, and one side of the wedge block is rotatably connected to a gear.
[0010] The utility model is further configured that a movable plate is rotatably connected to the top and bottom of one end of the gear, one end of the movable plate is rotatably connected to a second fixed block, a push rod is fixed to one side of the second fixed block, and the outer surface of the push rod is slidably connected to a conical block.
[0011] The utility model is further configured as follows: a rope is fixed to the bottom of the conical block, a second protective tube is provided on the outer surface of the conical block, a second spring is fixed to the top of the second protective tube, a first slide groove is fixed to one side of the second protective tube, a connecting shell is fixed to the top of the second spring, a plurality of groups of second teeth are provided inside the connecting shell, a plurality of groups of second slide grooves are fixed to the outer surface of the second teeth, a sawtooth tube is fixed inside the second teeth, a second slider is fixed to the outer surface of the sawtooth tube, a cam is provided inside the sawtooth tube, a plurality of first teeth are fixed to the outer surface of the cam, and the first teeth are slidably connected to the outer surface of the sawtooth tube, and a first protective tube is provided on the top of the second protective tube.

When the sawtooth tube rotates too much and disengages from the sawtooth of the sawtooth tube, it slides again. Since the first tooth shape has not returned to its original position, the conical block is fixed, and when the conical block is fixed, it drives the wedge block to be fixed.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0019] The following describes an embodiment of the utility model based on its overall structure.
[0020] A suspension frame for copper plating on the surface of a circuit board, as shown in Figure 1, includes a frame 1, wheel rods 3 are arranged on both sides of the frame 1, a cylinder 4 is installed at one end of the frame 1, a convex block 5 is fixed at one end of the cylinder 4, rollers 2 are arranged on both sides of the convex block 5, the rollers 2 are slidably connected to the outer surface of the wheel rod 3, a first fixed block 6 is fixed at one end of the convex block 5, a fixed plate 19 is arranged on the top of the first fixed block 6, and multiple groups of protective shells 17 are arranged on the top of the fixed plate 19.
[0021] It can be understood that the cylinder 4 pushes the convex block 5 to make the roller 2 slide on the outer surface of the wheel rod 3, and the roller 2 drives the fixed plate 19 to move.
[0022] As shown in Figure 3, a first slider 20 is fixed inside the protective shell 17, fixed piles 16 are fixed on both sides of the top of the first slider 20, a first spring 18 is fixed to one end of the fixed pile 16, a wedge block 8 is fixed to one end of the first spring 18, a rubber plate 7 is fixed to one end of the wedge block 8, one side of the wedge block 8 is rotatably connected to a gear 9, the top and bottom of one end of the gear 9 are rotatably connected to a movable plate 15, one end of the movable plate 15 is rotatably connected to a second fixed block 14, a push rod 13 is fixed to one side of the second fixed block 14, and the outer surface of the push rod 13 is slidably connected to a conical block 30.
[0023] It is understandable that when the conical block 30 moves downward, it squeezes the push rod 13 to move, and when the push rod 13 is pushed, the gear 9 is driven to rotate, and when the gear 9 rotates, it drives the wedge block 8 to clamp or open.
[0024] As shown in Figure 4, a rope 12 is fixed to the bottom of the conical block 30, and a second protective tube 11 is provided on the outer surface of the conical block 30, a second spring 21 is fixed to the top of the second protective tube 11, a first slide groove 22 is fixed to one side of the second protective tube 11, a connecting shell 29 is fixed to the top of the second spring 21, a plurality of groups of second teeth 28 are provided inside the connecting shell 29, a plurality of groups of second slide grooves 25 are fixed to the outer surface of the second teeth 28, a sawtooth tube 23 is fixed inside the second teeth 28, a second slider 24 is fixed to the outer surface of the sawtooth tube 23, a cam 26 is provided inside the sawtooth tube 23, a plurality of first teeth 27 are fixed to the outer surface of the cam 26, and the first teeth 27 are slidably connected to the outer surface of the sawtooth tube 23, and a first protective tube 10 is provided on the top of the second protective tube 11.
[0025] It can be understood that pulling the rope 12 drives the conical block 30 to move, and when the conical block 30 moves, it drives the second protective tube 11 and the parts arranged inside the first protective tube 10 to operate.
[0026] Working principle: The conical block 30 is moved downward by pulling the rope 12. When the conical block 30 moves downward, it squeezes the push rod 13 to slide out from the inside of the first slide groove 22. When the push rod 13 slides out, it pushes the second fixed block 14 to move. When the second fixed block 14 moves, the gear 9 is rotated through the movable plate 15. When the gear 9 rotates, it drives the wedge block 8 to clamp. Due to the existence of the first slider 20, the wedge block 8 moves laterally. When the wedge block 8 is clamped, the conical block 30 drives the connecting shell 29 to move. When the connecting shell 2 moves, it drives the serrated tube 23 to rotate. When the serrated tube 23 rotates, it squeezes the first tooth 27 to drive the cam 26 to rotate. The cam 26 rotates Turn to the saw teeth of the sawtooth tube 23, loosen the rope 12 so that the sawtooth tube 23 contacts the edge of the second tooth 28, causing excessive rotation. When the sawtooth tube 23 rotates too much and disengages from the saw teeth of the sawtooth tube 23, it slides again. Since the first tooth 27 has not returned to its original position, the conical block 30 is fixed. When the conical block 30 is fixed, it drives the wedge block 8 to be fixed. When loosened, pull the rope 12 again to cause the first tooth 27 to return to its original position, and the conical block 30 is no longer fixed. When the conical block 30 is no longer fixed, the second spring 21 rebounds to pull the conical block 30 upward. Since the conical block 30 is no longer squeezing the push rod 13, the first spring 18 rebounds to pull the wedge block 8 back and reset.
[0027] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
