[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-4 In one embodiment of this utility model, a foldable cleaning arm for cleaning a shielded door is disclosed. Specifically, the cleaning arm includes a main pipe section 1 and folded pipes 2 disposed at both ends of the main pipe section 1. In order to spray water to the outside to rinse the shielded door, several nozzles 7 are installed at intervals on the outer sides of the main pipe section 1 and the folded pipes 2 in this embodiment. In addition, a connecting plate is fixedly installed at the back end of the main pipe section 1. The connecting plate is used to connect the entire cleaning arm to a mobile trolley. Specifically, in this embodiment, the main pipe section 1 is used to connect to external water supply equipment, such as water pumps, water tanks, etc., so as to meet the water supply needs of the main pipe section 1 and the folded pipes 2.

[0028] Connecting seats 3 are fixed at both ends of the main pipe section 1, and the interior of the connecting seat 3 has a flow channel 31 that communicates with the inner cavity of the main pipe section 1;

[0029] A rotating seat 4 is fixedly installed at the end of the folded tube 2. The rotating seat 4 and the connecting seat 3 are connected and rotated through a connecting component 5 and are connected by water passage. A positioning component 6 is also provided between the rotating seat 4 and the connecting seat 3.

[0030] In some embodiments, the connecting seat 3 of this utility model has a U-shaped structure;

[0031] The connecting assembly 5 includes a shaft 51 fixed inside the connecting seat 3. The shaft 51 has a liquid cavity 52 inside, and the shaft 51 has an inlet hole 53 and an outlet hole 54 communicating with the liquid cavity 52 on the outside. One end of the flow channel 31 is connected to the inlet hole 53.

[0032] That is to say, in the embodiment, the shaft 51 is fixedly connected with the connecting seat 3, and the liquid inlet hole 53 is connected with the flow channel 31, so that the main pipe joint 1, the flow channel 31, the liquid inlet hole 53 and the liquid cavity 52 together form an input water path. When water is supplied in the main pipe joint 1, the water flows into the liquid cavity 52 through the input water path, and is then supplied out of the liquid outlet hole 54 and into the folding pipe 2, so as to supply water to the folding pipe 2.

[0033] Specifically, in the embodiment, the rotating seat 4 has a liquid delivery cavity 41 which is connected with the folding pipe 2.

[0034] The rotating seat 4 is rotatably connected to the outer side of the shaft 51, and an annular groove 42 is formed in the inner ring of the rotating seat 4. The annular groove 42 is sleeved on the outer side of the liquid outlet hole 54, and the annular groove 42 is connected with the liquid delivery cavity 41.

[0035] That is to say, when water is supplied in the main pipe joint 1, the water flows into the liquid cavity 52 along the input water path. Since the annular groove 42 is formed in the inner hole of the rotating seat 4, the annular groove 42 and the liquid outlet hole 54 are always in communication when the rotating seat 4 rotates circumferentially. Specifically, in the embodiment, the liquid outlet hole 54, the annular groove 42, the liquid delivery cavity 41 and the folding pipe 2 form an output water path. When the water in the liquid cavity 52 is discharged out of the liquid outlet hole 54, the water flows into the liquid delivery cavity 41 in the rotating seat 4 along the annular groove 42. Since the liquid delivery cavity 41 is connected with the folding pipe 2, the water in the main pipe joint 1 can be guided into the folding pipe 2, so as to complete the water supply of the whole cleaning arm.

[0036] Of course, in order to improve the sealing between the rotating seat 4 and the shaft 51 when the rotating seat 4 rotates, at least two sealing rings 43 are embedded in the inner hole of the rotating seat 4 in the embodiment, and the at least two sealing rings 43 are located on both sides of the annular groove 42.

[0037] On the basis of the above embodiment, in the embodiment, the piston 55 is movably inserted into the liquid cavity 52 of the shaft 51, the spring 56 is fixedly connected between the piston 55 and the inner wall of the liquid cavity 52, the pull rod 57 is movably inserted into the side end of the shaft 51, the inner end of the pull rod 57 is connected with the piston 55, and the outer end of the pull rod 57 is eccentrically pinned with the handle 58. Of course, a sealing ring which is attached to the handle 58 can also be arranged on the inner side of the shaft 51. In the embodiment, the top of the handle 58 is in a circular structure which is eccentrically pinned with the pull rod 57, so as to form a cam structure. When the handle 58 rotates, the side with a larger thickness of the handle 58 abuts against the side edge of the shaft 51, so that the piston 55 is moved by the pull rod 57. The outer wall of the handle 58 abuts against the side end of the shaft 51.

[0038] Specifically, in the embodiment, the piston 55 is arranged to seal the liquid outlet hole 54, when the folding pipe 2 is folded, the handle 58 is rotated, and since the handle 58 is connected in an eccentric manner, when the handle 58 abuts against the end of the shaft 51, the handle 58 pulls the pull rod 57 to move outward, so that the piston 55 is pulled to move linearly by the pull rod 57, and when the piston 55 moves to the lower side of the liquid outlet hole 54, the liquid outlet hole 54 is sealed, so that the water outlet is closed, and the water path of the folding pipe 2 is closed in the folded state, and the main pipe section 1 can be used alone.

[0039] It should be noted that the positioning assembly 6 in the embodiment includes a through hole formed in the connecting seat 3, the positioning bead 61 and the compression spring 62 are movably connected in the through hole, and the compression block 63 is threadedly connected to the outer side of the through hole, and in the embodiment, part of the positioning bead 61 protrudes outward of the through hole, and the compression block 63 is threadedly connected, and the purpose of the compression block 63 is to adjust the screw depth of the compression block 63 to change the pressing force of the positioning bead 61.

[0040] The rotating seat 4 is provided with a plurality of positioning holes 64 on the outer side, the positioning bead 61 is clamped in the positioning hole 64, and in the embodiment, the rotating seat 4 is angularly positioned by clamping the positioning bead 61 in the positioning hole 64, and in use, the folding pipe 2 is swung to rotate, and when the positioning bead 61 is positioned in the current positioning hole 64, the angle is limited, and the operation is simple and convenient.

[0041] In summary, in the utility model, two rotatable folding pipes 2 are arranged at the two ends of the main pipe section 1, the two folding pipes 2 are folded above the main pipe section 1, and the occupied space is saved, the water path between the main pipe section 1 and the folding pipe 2 is controllable, the water path of the folding pipe 2 is closed in the folded state, and the main pipe section 1 can be used alone, and the overall applicability of the cleaning arm is further improved.

[0042] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, and all should be covered in the protection scope of the utility model.
