Description

Technical Field

[0001] The utility model relates to the field of air shaft installation equipment, and particularly relates to a fastening tool for an air shaft. Background Technique

[0002] In the industrial printing field, the air shaft is one of the commonly used printing and dyeing equipment. When in use, the air shaft needs to be first installed and fixed on the bracket, and then during the printing process, the air shaft will reciprocate along the fixed frame under the drive of the bracket. At the same time, the air shaft will also rotate circumferentially synchronously with the bracket. When fixing the air shaft on the bracket or disassembling it from the bracket for replacement, since the bracket itself will rotate, it will drive the air shaft to rotate, resulting in difficulty in locking or loosening the fixing bolts, increasing the workload.

[0003] Therefore, our company proposes a fastening tool for an air shaft. Summary of the Invention

[0004] The purpose of the utility model is to provide a fastening tool for an air shaft, which can conveniently install the air shaft on the bracket or disassemble it from the bracket.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fastening tool for an air shaft, the end of the air shaft has a flange, and the flange is installed on the bracket through the fixing holes opened thereon. The bracket is installed on the fixed frame, and a slot for facilitating the reciprocating movement of the bracket is opened on the fixed frame. The fastening tool for the air shaft includes a fixed clamping plate, a handle is arranged on one side of the fixed clamping plate, an anti-rotation part is arranged on the other side of the fixed clamping plate, and an anti-rotation protrusion that can extend into the fixing hole is arranged on the anti-rotation part.

[0007] Preferably, a limit clamping block that can extend into the slot is arranged at the bottom of the fixed clamping plate.

[0008] Preferably, a step for preventing the fixed clamping plate from entering the slot is formed between the limit clamping block and the main body of the fixed clamping plate.

[0009] Preferably, the limit clamping block is square.

[0010] Preferably, a limit clamping block is arranged at the bottom of the fixed clamping plate, and a step is formed between the limit clamping block and the main body of the fixed clamping plate.

[0011] Preferably, a grasping gap is formed between the handle and the fixed clamping plate.

[0012] Preferably, the fixed clamping plate is connected to the anti-rotation part through a mounting plate.

[0013] Preferably, the fixed clamping plate is connected to the mounting plate by bolts.

[0014] Preferably, the anti-rotation protrusion is cylindrical.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. When in use, hold the handle with one hand and insert the anti-rotation protrusion into the fixing hole of the air-expansion shaft, then the rotation of the air-expansion shaft can be prevented, and then it can be easily fixed on the bracket or removed from the bracket.

[0017] 2. Through the limit block, the fixing card plate can be smoothly clamped in the fixing frame, making the work of stably fixing the card plate easier.

[0018] 3. By connecting the bolt with the mounting plate and the anti-rotation part, different anti-rotation parts can be replaced according to different apertures of the air-expansion shaft, improving the applicability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present utility model will be further described below with reference to the drawings.

[0025] Embodiment 1

[0026] As Figure 4As shown in the figure, it is a schematic installation diagram of an air shaft. The end of the air shaft 10 has a flange 11. The bracket 12 is installed on the fixed frame 13. The upper end of the bracket 12 has a disc. Both the flange 12 and the disc are provided with fixing holes 15 for fixing and corresponding one by one. By screwing bolts into the fixing holes 15, the flange 11 can be fixed on the disc, realizing the fixation of the air shaft 10. The wall thickness of the flange 12 is greater than the thickness of the bolt nut. After screwing the bolt into the fixing hole 15, the distance between the upper end face of the nut and the end face of the fixing hole 15 is also sufficient to place the anti-rotation protrusion 7 in this application. After fixation, the bracket 12 can drive the air shaft 10 to move up and down along the fixed frame 13. The fixed frame 13 is provided with a slot 14 to facilitate the up and down movement of the bracket.

[0027] As Figure 1 — Figure 3 As shown in the figure, a fastening tooling for an air shaft in this embodiment includes a fixed clamping plate 1. One side of the fixed clamping plate 1 is provided with a handle 3, and the other side of the fixed clamping plate 1 is provided with an anti-rotation part 6, and the anti-rotation part 6 is provided with an anti-rotation protrusion 7. When in use, hold the handle 3 with one hand, put the anti-rotation protrusion 7 into one of the fixing holes 15, and tighten the remaining fixing holes 15. Then replace the fixing hole 15 into which it is placed to realize the tightening of all the fixing holes 15. To facilitate the cooperation between the anti-rotation protrusion 7 and the fixing hole 15, the anti-rotation protrusion 7 is set as a cylinder. In some embodiments, a bolt can be used as the anti-rotation part 6, and one end of the bolt serves as the anti-rotation protrusion 7 and penetrates into the fixing hole 15 to realize the fixation of the air shaft 10, which can save costs.

[0028] The bottom of the fixed clamping plate 1 is provided with a square limit clamping block 4. When in use, to facilitate the positioning of the fixed clamping plate 1, the width of the limit clamping block 4 can be set to be the same as that of the slot 14, so that the limit clamping block 4 can be smoothly placed into the slot 14, and then the air shaft 10 can be fixed conveniently. To prevent the fixed clamping plate 1 from falling into the slot 14, a step is formed between the limit clamping block 4 and the main body of the fixed clamping plate 1.

[0029] A grasping gap is formed between the handle 3 and the fixed clamping plate 1 to facilitate the worker to grasp the device.

[0030] The fixed clamping plate 1 is connected to the anti-rotation part 6 through a mounting plate 5. The fixed clamping plate 1 is connected to the mounting plate 5 through bolts 2. When in use, the anti-rotation part 6 can be welded to the mounting plate 5 as a whole. When the size of the fixing hole 15 of the air shaft 10 to be installed or disassembled changes, different mounting plates 5 can be replaced to realize the replacement of the anti-rotation part 6 with different sizes of anti-rotation protrusions 7, improving the applicability of the equipment.

[0031] When this embodiment is in use, first, fix the mounting plate 5 with an anti-rotation protrusion 7 of appropriate size through the bolt 2. Then, hold the handle 3 and insert the limit catch 4 into the slot 14 of the fixing frame 13. Rotate the air shaft 10 so that the anti-rotation protrusion 7 corresponds to and inserts into a fixing hole 15. Then, the remaining fixing holes 15 can be tightened or disassembled. After that, rotate the air shaft 10 to replace the fixing hole 15 that cooperates with the anti-rotation protrusion 7, so as to tighten or disassemble all the fixing holes 15.
