Figure 2 This is illustrated according to an exemplary embodiment. Figure 1 The middle section is an enlarged view of part A, showing the structure of the accessory fixing assembly. The following section is in conjunction with... Figure 1 and Figure 2 To explain.
[0025] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.
[0026] Reference Figure 1 and Figure 2 This disclosure provides an exemplary embodiment of a railway open wagon ventilation auxiliary device, which includes:
[0027] The telescopic rod 1 has multiple telescopic sections 9 that can extend and retract in stages, and adjacent telescopic sections 9 are fixed together by a drum locking member. At least one telescopic section 9 has a hook 3 at its end.
[0028] The accessory fixing assembly 2 includes a baffle 24 fixed to the telescopic joint 9, a pressure plate 23 movably connected to the telescopic joint 9, and an elastic member 22 fixed to the telescopic joint 9 and used to drive the pressure plate 23 to move toward the baffle 24.
[0029] The lighting lamp 7 is fixed on the expansion joint 9 and is positioned facing the hook 3.
[0030] For example, refer to Figure 1 and Figure 2 There are multiple telescopic joints 9, for example, three, namely a first connecting joint 11, a second connecting joint 12, and a third connecting joint 13 arranged coaxially. The first connecting joint 11 is sleeved on the second connecting joint 12, and the second connecting joint 12 is sleeved on the third connecting joint 13. One end of the third connecting joint 13 can extend out from the inside of the second connecting joint 12. The end of the third connecting joint 13, which is inside the second connecting joint 12, is fixed with a drum locking component. One end of the second connecting joint 12 can extend out from the inside of the first connecting joint 11. The end of the second connecting joint 12, which is fixed inside the first connecting joint 11, is also fixed with a drum tightening component. When both the second connecting joint 12 and the third connecting joint 13 are extended, the telescopic rod 1 has a rod-like structure with two stepped diameter reduction sections from one end to the other. The telescopic rod 1 can be understood as a baton. The hook 3 is integrally formed on the end of the third connecting joint 13 that can extend. The inner wall of the hook 3 is provided with multiple slots 31. The slots 31 penetrate part of the solid structure of the hook 3 along the direction perpendicular to the bending area of the hook 3. The slots 31 are distributed at intervals along the bending direction of the hook 3.
[0031] The accessory fixing assembly 2 also includes a fixing plate 21 fixed to the telescopic joint 9. The fixing plate 21 is sleeved and fixed to the first connecting joint 11. The outer edge of the fixing plate 21 extends beyond the outer wall of the first connecting joint 11. The baffle 24 is sleeved and fixed to the end of the first connecting joint 11. The outer edge of the baffle 24 extends beyond the outer wall of the first connecting joint 11. The pressure plate 23 is sleeved on the first connecting joint 11 and can slide relative to the first connecting joint 11 along the axis of the first connecting joint 11. The pressure plate 23 is located in the area between the baffle 24 and the fixing plate 21. The elastic element 22 includes a spring fixed to the fixing plate 21 and abutting against the pressure plate 23. The spring is parallel to the axial direction of the first connecting joint 11. One end of the spring is fixed to the fixing plate 21 and the other end is fixed to the pressure plate 23. There are multiple springs and they are distributed circumferentially to push the pressure plate 23 toward the baffle 24.
[0032] A recessed fixing groove 241 is provided on the side of the baffle 24 facing the pressure plate 23. The fixing groove 241 extends from the end of the baffle 24 facing the pressure plate 23 into the baffle 24. The fixing groove 241 communicates with the outer wall of the first connecting section 11. The opening of the fixing groove 241 is set towards the pressure plate 23. The inner wall of the opening of the fixing groove 241 is inclined towards the pressure plate 23 to form a flared part 242. This provides a guiding effect for the recorder that is about to be inserted into the fixing groove 241 and clamped between the pressure plate 23 and the baffle 24, so that the part of the physical structure of the recorder facing the baffle 24 can be smoothly inserted into the fixing groove 241. The fixing groove 241 also reduces the possibility of the recorder detaching from the pressure plate 23 and the baffle 24.
[0033] In this embodiment, the recorder is fixed to the telescopic joint 9 by the accessory fixing component 2, so that all the telescopic joints 9 are extended. The user holds one telescopic joint 9 located at the end, so that the telescopic joint 9 with the hook 3 faces the target position, and turns on the light 7. Manual ventilation is achieved by pulling the hook 3. By extending the range of hand operation, the possibility of the user being in a dangerous environment is reduced, and the hand-held parts are integrated, freeing up one of the user's operating hands and providing more operational redundancy for the operator.
[0034] In an exemplary embodiment of this disclosure, reference is made to Figure 1 The lighting lamp 7 is in the shape of a ring around the telescopic joint 9, and the end of the telescopic joint 9 has a stop 8 for preventing the lighting lamp 7 from disengaging from the current telescopic joint 9.
[0035] For example, refer to Figure 1 The lighting lamp 7 is mounted on the second connecting section 12 and faces the third connecting section 13. The lighting lamp 7 can be battery powered and is interference-fitted with the second connecting section 12, allowing the lighting lamp 7 to remain at any position on the second connecting section 12. A stop block 8 is fixed to the end of the second connecting section 12 opposite to the first connecting section 11. The stop block 8 extends from the end edge of the second connecting section 12 to the outside of the second connecting section 12 to prevent the lighting lamp 7 from detaching from the end of the second connecting section 12.
[0036] In an exemplary embodiment of this disclosure, reference is made to Figure 1 and Figure 2 At least one telescopic joint 9 has a hook 5, the hook 5 is spaced apart from the telescopic joint 9 to form a hanging space 4 for the entry of external entities, and the hook 5 has a locking part 51 that bends and abuts against the telescopic joint 9.
[0037] For example, refer to Figure 1 and Figure 2One end of the hook 5 is fixed to the end of the first connecting section 11 by a hand-tightening bolt 6. The hook 5 can be rotated by loosening the hand-tightening bolt 6. The other end of the hook 5 extends outward from the first connecting section 11, and after reaching the outside of the first connecting section 11, it extends obliquely towards the first connecting section 11. The other end of the hook 5, which extends obliquely downward towards the first connecting section 11, changes its extension direction near the side wall of the first connecting section 11 and continues to extend obliquely downward away from the first connecting section 11. The hanging space 4 is formed between the hook 5 and the outer wall of the first connecting section 11. The hook 5, which changes its extension direction near the side wall of the first connecting section 11, forms a locking part 51.
