[0008] Preferably, the mounting base has through holes on both sides of its surface, and one end of the positioning screw is inserted into the through hole of the mounting base. The positioning screw and the first nut are rotatably connected by a thread.

[0009] Preferably, the top surface of the mounting base has mounting grooves on both sides, and the fixing screw is inserted into the mounting grooves of the mounting base.

[0010] Preferably, the bottom end of the fixing screw is connected to one side of the top surface of the ladder, and the fixing screw and the second nut are rotatably connected by a thread.

[0011] Preferably, the mounting base is connected to limiting structures on both sides. The limiting structure includes a fixing frame, and positioning plates are connected to the upper and lower surfaces of the fixing frame. A control ring is sleeved on the outer wall of the positioning plate, and a limiting rod is connected to the inner surface of the control ring. A support spring is connected to one side of the outer surface of the limiting rod.

[0012] Preferably, the positioning plate has a movable groove on its surface, one end of the support spring is connected to one side of the inner wall of the movable groove in the positioning plate, the mounting base has slots on both sides, the ladder has a limit groove on one side, and one end of the limit rod passes through the support spring and the mounting base and is inserted into the limit groove in the ladder.

[0013] Preferably, the fixing frame and the limiting rod are elastically connected by a support spring, and the control ring has grooves on both sides, with the positioning plate inserted into the grooves of the control ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By fitting the mounting base onto the outer wall of the fixing screw, the fixing screw is used to position the tank and the mounting base. Then, the second nut is rotated and connected to the outer surface of the top of the fixing screw to fix the mounting base. Next, the positioning screw connected to one end of the limiting ring is inserted into the through hole of the mounting base to position the ladder and the mounting base. Then, the first nut is rotated and connected to the outer surface of one end of the positioning screw, so that the limiting ring and the first nut clamp and fix the mounting base, thereby restricting the position of the ladder and achieving the desired assembly effect between the tank and the ladder. This avoids the problem of inconvenience in climbing caused by workers carrying different sizes of tools and the inability to replace the ladder.

[0016] 2. By pulling the control ring, the limit rod is compressed and retracted by the support spring, thus retracting the limit rod into the slot opened in the mounting base. After the ladder is installed, the control ring is released, allowing the support spring to support the limit rod and reset it. This causes the positioning plate to move and limit the control ring, and one end of the limit rod is inserted into the limiting slot opened in the ladder. The limit rod is used to limit the angle of the ladder, thereby achieving the angle limitation and limiting effect of the ladder. Attached Figure Description

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.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] An electric multi-functional suction and exhaust truck includes:

[0026] The suction and exhaust vehicle body 1 includes a frame 11, a tank 12 is provided on the surface of the frame 11, and a ladder 13 is provided on one side of the top of the tank 12. The internal material of the ladder 13 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application, so no further details are made.

[0027] The ladder 13 is connected to the two ends of the assembly structure 2. The assembly structure 2 includes a limiting ring 21. One end of the limiting ring 21 is connected to a positioning screw 22. The outer wall of the positioning screw 22 is sleeved with a mounting base 23. One end of the positioning screw 22 is rotatably connected to the outer surface of the outer end of the positioning screw 22. The top two sides of the mounting base 23 are internally inserted with fixing screws 25. The top outer surface of the fixing screw 25 is rotatably connected to a second nut 26.

[0028] Furthermore, through holes are provided on both sides of the surface of the mounting base 23. One end of the positioning screw 22 is inserted into the through hole of the mounting base 23. The positioning screw 22 and the first nut 24 are connected by threads to achieve a connection and fixation between the positioning screw 22 and the first nut 24 through threads, thereby using the limiting ring 21 in conjunction with the first nut 24 to limit the positioning screw 22.

[0029] Furthermore, mounting slots are provided on both sides of the top surface of the mounting base 23, and the fixing screw 25 is inserted into the mounting slots of the mounting base 23. This allows the fixing screw 25 to be positioned by the mounting slots of the mounting base 23, and the fixing screw 25 to restrict the mounting base 23.

[0030] Furthermore, the bottom end of the fixing screw 25 is connected to one side of the top surface of the ladder 13, and the fixing screw 25 and the second nut 26 are rotated together by threads, so as to fix the fixing screw 25 and the second nut 26 by threads, thereby limiting the position between the tank body 12 and the mounting base 23.

[0031] Furthermore, the mounting base 23 is connected to the two sides of the limiting structure 3. The limiting structure 3 includes a fixing frame 31. The upper and lower end surfaces of the fixing frame 31 are connected to the positioning plate 32. The outer wall of the positioning plate 32 is sleeved with a control ring 33. The inner surface of the control ring 33 is connected to the limiting rod 34. The outer surface of the limiting rod 34 is connected to a support spring 35. The angle of the ladder 13 is limited by the limiting rod 34, thereby achieving the angle limitation and limiting effect of the ladder 13.

[0032] Furthermore, the positioning plate 32 has a movable groove on its surface, one end of the support spring 35 is connected to one side of the inner wall of the movable groove in the positioning plate 32, the mounting base 23 has slots on both sides, the ladder 13 has a limit groove on one side, and one end of the limit rod 34 passes through the support spring 35 and the mounting base 23 and is inserted into the limit groove in the ladder 13, so that the limit rod 34 is positioned by the limit groove in the ladder 13 and the angle of the ladder 13 is limited by the limit rod 34.

[0033] Furthermore, the fixed frame 31 and the limiting rod 34 are elastically connected by a support spring 35. The control ring 33 has grooves on both sides, and the positioning plate 32 is inserted into the grooves of the control ring 33. The positioning plate 32 is positioned by the grooves of the control ring 33, and the positioning plate 32 is used to limit the movement of the control ring 33.

[0034] Working principle: When assembling the electric multi-functional suction and exhaust vehicle, the mounting base 23 is sleeved on the outer wall of the fixing screw 25, and the fixing screw 25 is used to position the tank 12 and the mounting base 23. Then, the second nut 26 is rotated and connected to the outer surface of the top end of the fixing screw 25, thereby fixing the mounting base 23. Then, the positioning screw 22 connected to one end of the limiting ring 21 is inserted into the through hole opened in the mounting base 23 to position the ladder 13 and the mounting base 23. Then, the first nut 24 is rotated and connected to the outer surface of one end of the positioning screw 22, thereby using the limiting ring 21 and the first nut 24 to clamp and fix the mounting base 23, thereby restricting the position of the ladder 13 and achieving the assembly effect between the tank 12 and the ladder 13.

[0035] When the electric multi-functional suction and exhaust cart is limited, the control ring 33 is pulled to compress the support spring 35 and retract it, so that the limit rod 34 retracts into the slot opened in the mounting base 23. After the ladder 13 is installed, the control ring 33 is released, so that the support spring 35 supports the limit rod 34 to return to its original position, so that the positioning plate 32 moves and limits the control ring 33, and one end of the limit rod 34 is inserted into the limiting slot opened in the ladder 13. The limit rod 34 is used to limit the angle of the ladder 13, thereby achieving the effect of limiting and restricting the angle of the ladder 13.
