Description

Technical Field

[0001] The utility model relates to the field of spraying, in particular to a hook for spraying. Background Art

[0002] During the spraying process of workpieces, the workpieces need to be installed on special spraying hooks to facilitate all-round spraying. However, this type of spraying hook has great shortcomings: 1) Each workpiece corresponds to a hook, which leads to its lack of versatility and increases production costs; 2) The hooks are generally fixed on the connecting rods by welding, which makes it impossible to adjust the relative distance and angle between the hooks. In order to avoid the occurrence of position obstruction between workpieces, the only solution is to reduce the number of suspended workpieces, thereby reducing the spraying efficiency. Utility Model Content

[0003] Purpose of the utility model: The purpose of the utility model is to provide a hook for spraying, which solves the problems existing during spraying.

[0004] Technical solution: The utility model provides a hook for spraying, including a support rod and a hook assembly, wherein the hook assembly has several groups and is arranged in parallel on the support rod; wherein the hook assembly includes a fixed structure, a connecting rod structure, and a hook, wherein the connecting rod structure is arranged on the fixed structure, and the hook has several groups and is arranged on the connecting rod structure; the connecting rod structure includes a first long rod, a second long rod, a first short rod, a second short rod, and a locking structure, wherein the middle position of the first long rod and the second long rod is arranged on the fixed structure, and the two ends are respectively connected to the ends of the first short rod and the second short rod, and are fixed by the locking structure. According to the size of the workpiece to be sprayed, the relative angles between the first long rod, the second long rod, the first short rod, and the second short rod of the connecting rod structure of the hook assembly are adjusted, and fixed by the locking structure, so that the workpieces are placed on the hook in sequence. The connecting rod structure design is not only simple in structure and easy to operate, but also effectively avoids the occurrence of shielding between workpieces while spraying more workpieces at one time, and has wide applicability.

[0005] Furthermore, the support rod comprises a first fixed section, a connecting section, and a mounting section which are connected in sequence; a guide strip centered on the axis of the mounting section is provided on the side wall of the mounting section; and a plurality of first through holes are also provided on the side wall of the mounting section. The first fixed section of the support rod facilitates the installation of the entire hook on the spraying frame, and the mounting section is used to install the hook assembly. The mounting section is provided with a plurality of first through holes, so that the installation distance of adjacent hook assemblies can be adjusted according to the actual size of the spraying workpiece.

[0006] Furthermore, the fixing structure includes a fixing seat, a pressure plate, and a mounting assembly. The pressure plate is arranged at one end of the fixing seat, and the mounting assembly is arranged at the other end of the fixing seat to mount the fixing seat on the support rod. The outer side of the fixing seat includes a connecting rod mounting section, a limiting section, and a fixing section connected in sequence, and the side wall of the fixing section is provided with a second through hole. The upper end of the fixing seat is provided with a first threaded hole. The middle of the fixing seat is provided with a mounting hole, and the side of the mounting hole is provided with a guide groove. The middle position of the pressure plate is provided with an avoidance hole, and the side thereof is provided with a countersunk hole. The fixing structure is mounted on the support rod through the mounting hole and is quickly fixed by the mounting assembly. The bolt passes through the countersunk hole of the pressure plate and is locked into the first threaded hole of the fixing seat, thereby playing a fixing role, thereby pressing the connecting rod structure with the angle adjusted on the connecting rod mounting section, and the operation is simple and convenient.

[0007] Furthermore, the mounting assembly includes an axle pin and a split pin. After the axle pin passes through the first through hole on the support rod and the second through hole of the fixing seat, it is fixed by the split pin. The structure is simple and the assembly and disassembly is convenient.

[0008] Furthermore, the first long rod and the second long rod have the same structure, including an intermediate mounting ring, a first rod, and a second rod, and the first rod and the second rod are arranged side by side on both sides of the intermediate mounting ring. The first long rod and the second long rod are mounted on the connecting rod mounting section of the fixing seat through the intermediate mounting ring, so that the angle between the two can be adjusted when the pressure plate is released. In this embodiment, the intermediate mounting ring and the connecting rod mounting section are loosely matched, so as to facilitate adjustment.

[0009] Furthermore, the ends of the first rod and the second rod away from the middle mounting ring are provided with third through holes; the first rod and the second rod are also provided with a plurality of second threaded holes arranged in parallel. The third through holes are used for the locking structure to perform locking actions; the second threaded holes are used for fixing the hooks.

[0010] Furthermore, the first short rod and the second short rod have the same structure, and fourth through holes are provided at both ends of the first short rod and the second short rod; the first short rod and the second short rod are also provided with third threaded holes. The fourth through hole is used for the locking structure to perform locking action; the third threaded hole is used to fix the hook.

[0011] Furthermore, the hook includes a locking section, an extension section, and a hanging section connected in sequence; the locking section is provided with a fifth through hole. According to the workpiece to be sprayed, an extension section with a suitable length and angle and a hanging section with a suitable outer size are selected, and the locking section is locked into the second threaded hole or the third threaded hole on the connecting rod structure through the fifth through hole of the locking section. The installation of different types of hooks avoids obstruction between workpieces.

[0012] Furthermore, the locking structure includes a bolt and a butterfly nut, wherein the butterfly nut is arranged on the stud section of the bolt. By loosening or tightening the butterfly nut, the angles between the first long rod, the second long rod, the first short rod and the second short rod can be quickly adjusted, and the operation is simple and convenient.

[0013] It can be seen from the above technical scheme that the utility model has the following beneficial effects: 1) A connecting rod structure is provided, so that the specific hanging angle and distance between the hook components can be adjusted according to the specific size of the workpiece to be sprayed, so that when more workpieces are sprayed at one time, the occurrence of obstruction between the workpieces is effectively avoided, and the spraying efficiency is greatly improved; 2) The hook on the spraying hook is detachable, and the type of hook can be replaced or the distance between the hooks can be adjusted according to the specific external dimensions of the actual spraying workpiece. It has a simple structure, is easy to operate, and has wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS
