The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.
Please refer to fig. 1: the utility model discloses a movable pipe assembly, which comprises a fixed pipe 1, a movable pipe 3 and a driving device. Wherein one end of the stationary pipe 1 is provided with a first stationary flange 2. One end of the movable tube 3 is provided with a second fixed flange 4 and a movable flange 5. The second fixed flange 4 is close to the end of the end with respect to the movable flange 5. The movable flange 5 is connected with the first fixed flange 2 by bolts 6, and the second fixed flange 4 is clamped between the first fixed flange 2 and the movable flange 5, so that rotatable connection is realized between the first fixed flange 2 and the second fixed flange 4, or between the fixed pipe 1 and the movable pipe 3.
The drive means are used to drive the movable tube 3 in rotation about the axis of the second fixing flange 4. Of course, the movable tube 3 may be driven to rotate directly by a manual operation without providing a driving device.
When the movable tube 3 is driven to rotate, the first fixed flange 2 and the movable flange 5 remain connected without rotation. The second fixing flange 4, which is sandwiched between the first fixing flange 2 and the movable flange 5, is rotated against the clamping force with the first fixing flange 2 and the movable flange 5.
In the utility model, the movable pipe assembly is not required to be disassembled, and only an external force is required to be applied to the movable pipe 3 to drive the movable pipe 3 to rotate. If the movable 3 component is applied to the three-bend water gun, the nozzle angle of the three-bend water gun can be conveniently adjusted, and the three-bend water gun can be conveniently adjusted for multiple times, so that the usability of the three-bend water gun is improved.
The first fixing flange 2 is fixed to the fixing tube 1, the second fixing flange 4 is fixed to the movable tube 3, and the movable flange 5 is rotatable with respect to the movable tube 3. During the rotation of the movable tube 3, the second fixed flange 4 rotates in synchronization with the movable tube 3, and the movable flange 5 remains stationary with respect to the movable tube 3.
Referring to fig. 2, in the embodiment of the present utility model, an arc hole section 11 is provided on the second fixing flange 4 of the movable pipe 3, the arc hole section 11 extending around the axis of the second fixing flange 4, and bolts 6 for connecting the first fixing flange 2 and the movable flange 5 passing through the arc hole section 11. Since there are a plurality of bolts 6 for connecting the first fixed flange 2 and the movable flange 5, there are also a plurality of arc hole segments 11, and a plurality of arc hole segments 11 are arranged at intervals around the axis of the second fixed flange 4, each arc hole segment 11 being passed by one bolt 6. Since the arc hole section 11 extends around the axis of the second fixing flange 4, the cooperation of the arc hole section 11 and the corresponding bolt 6 forms a guiding effect on the rotation of the second fixing flange 4, ensuring that the second fixing flange 4 accurately rotates around the axis of the second fixing flange 4, so as to ensure that the fixed pipe 1 and the movable pipe 3 are always butted.
The driving means comprises a motor 9, and the motor 9 can drive the movable tube 3 to rotate in a chain transmission or belt transmission mode. In view of the driving accuracy, the embodiment of the present utility model adopts gears to drive the movable tube 3 to rotate. The drive means thus comprise in particular a motor 9 and a gear wheel 10, the gear wheel 10 being connected to the rotor of the motor 9. A driven gear engaged with the gear 10 may be provided on the movable tube 3, i.e., the driven gear is fitted around the movable tube 3. The motor 9 drives the gear 10 to rotate, and the gear 10 drives the movable tube 3 to rotate through the driven gear.
The embodiment of the present utility model combines the driven gear and the second fixing flange 4 into one body in view of the simplified structure. I.e. teeth engaging with the gear wheel 10 are provided on the circumference of the second mounting flange 4, and the motor 9 drives the movable tube 3 to rotate via the gear wheel 10 and the second mounting flange 4.
If the driven gear and the second fixing flange 4 are integrated, it is completely possible to arrange the motor 9 on the fixing tube 1 without having to find further mounting points for the motor 9, since the second fixing flange 4 is located closer to the fixing tube 1. Specifically, a bracket is provided on the fixed tube 1, and the motor mount of the motor 9 is connected to the bracket, so that the fixed tube 1, the movable tube 3, and the driving device form a whole that is connected to each other.
In order to buffer the friction between the second fixed flange 4 and the movable flange 5, a rubber pad 7 is disposed between the second fixed flange 4 and the movable flange 5 in the embodiment of the present utility model.
The rubber pad 7 is sleeved on the movable pipe 3, and a round hole for the bolt 6 to pass through is formed in the rubber pad 7, and the bolt 6 is used for connecting the movable flange 5 and the first fixed flange 2. Due to the cooperation of the bolts 6 and the round holes, the rubber pad 7 is almost kept still in the process of rotating the second fixing flange 4, so that smooth rotation of the second fixing flange 4 is ensured.
In order to improve the tightness of the connection between the fixed pipe 1 and the movable pipe 3, the present embodiment provides a sealing ring 8 between the first fixed flange 2 and the second fixed flange 4. A sealing groove matched with the sealing ring 8 is arranged on the first fixing flange 2 or the second fixing flange 4.
The utility model also discloses a three-bend front flushing gun, which comprises a water inlet pipe 12, a first bent pipe 13, a straight pipe 14, a second bent pipe 15 and a nozzle 16 which are connected in sequence. In particular, the inlet pipe 12 is any one of the fixed pipes 1 described above, and the first elbow pipe 13 is any one of the movable pipes 3 described above.
