[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a quick connection mechanism for water pipes, including a first water pipe 1 and a second water pipe 2. The first water pipe 1 and the second water pipe 2 are respectively the water pipes inside the ejector rod and the water pipes inside the trolley. A connector one 3 is fixedly connected to the outer wall of the first water pipe 1. The shape of the connector one 3 is a circular ring that fits the shape of the outer wall of the first water pipe 1, and a plurality of cuboids with rounded arcs at the edges are provided at the right end of the connector one 3. Through the shape setting of the connector one 3, it is ensured that the connector one 3 fixes the first water pipe 1 well through the cuboid part. A connector two 4 is fixedly connected to the outer wall of the second water pipe 2. The shape of the connector two 4 is a circular ring that fits the shape of the outer wall of the second water pipe 2, and a concave convex block is provided on the outer wall of the connector two 4. The inner wall width of the concave convex block of the connector two 4 fits the width of the cuboid part of the connector one 3. Through the shape settings of the connector two 4 and the connector one 3, it is ensured that the connector two 4 and the connector one 3 can be connected more conveniently. A sealing ring 5 is fixedly connected to the inner wall of the connector one 3. The shape of the sealing ring 5 is a ring, and the material of the sealing ring 5 is rubber. Through the shape and material settings of the sealing ring 5, it is ensured that water is not easily leaked from the connection part after the connector one 3 and the connector two 4 are connected.
[0033] Refer to Figure 2 - Figure 4 , the connector one 3 and the connector two 4 are connected through a connecting device 6. A connecting hole one 61 is opened in the inner wall of the connector one 3, and a connecting hole two 62 is opened in the inner wall of the connector two 4. The shapes of the connecting hole one 61 and the connecting hole two 62 are the same and their positions fit. A pin shaft 63 slides in the inner wall of the connecting hole one 61. The diameter of the pin shaft 63 is smaller than the diameters of the connecting hole one 61 and the connecting hole two 62. Through the size setting, it is ensured that the pin shaft 63 can enter the interiors of the connecting hole one 61 and the connecting hole two 62 more easily. An installation block 66 is fixedly connected to the front end of the pin shaft 63. The shape of the installation block 66 is a block with horizontal planes at the top and bottom and a hole in the middle.
[0034] Refer to Figure 2 - Figure 4, an air pressure chamber 64 is provided on the inner wall of the pin shaft 63. A piston on the inner wall of the air pressure chamber 64 is connected to a sliding plate 65. The outer wall of the sliding plate 65 fits against the inner wall of the air pressure chamber 64. A screw rod 67 is rotatably connected to the rear end of the sliding plate 65. A threaded hole that fits the screw rod 67 is provided at the rear end of the pin shaft 63. A fixing block 68 is fixedly connected to the rear end of the screw rod 67. The shape of the fixing block 68 is the same as that of the mounting block 66. An airbag 69 is fixedly connected to the outer wall of the pin shaft 63. The shape of the airbag 69 is annular, and the length of the airbag 69 is the same as the length of the protruding part of the second connector 4. Through this length setting, it is ensured that after the airbag 69 expands, it can fit against the inner walls of both the first connection hole 61 and the second connection hole 62 simultaneously. The front end of the sliding plate 65 is elastically connected to the inner wall of the air pressure chamber 64 by a spring 610. One end of the spring 610 is fixedly connected to the front end of the sliding plate 65, and the other end of the spring 610 is fixedly connected to the inner wall of the air pressure chamber 64. A fixing hole 611 is provided in the inner wall of the first connector 3.
[0035] Refer to Figure 3 - Figure 5 , a fixing component 7 slides in the inner wall of the fixing hole 611. The fixing component 7 includes a split pin 71. The shape of the split pin 71 is a hollow tubular object, and a plurality of notches are provided at the bottom end of the split pin 71. Through the setting of the notches, it is ensured that the bottom end part of the split pin 71 can deflect outwards. A turntable 72 is fixedly connected to the inner wall of the split pin 71. An arc-shaped sliding groove 73 is provided in the inner wall of the turntable 72. A sliding rod 74 is arranged inside the sliding groove 73. The shape of the sliding rod 74 is L-shaped. A mounting piece 75 is fixedly connected to the inner wall of the split pin 71. The shape of the mounting piece 75 is annular. The bottom end of the mounting piece 75 is slidably connected to the top end of the sliding rod 74. A push plate 76 is fixedly connected to the bottom end of the sliding rod 74. A control rod 77 penetrates and slides through the inner wall of the turntable 72. The control rod 77 penetrates the inner wall of the mounting piece 75, and the diameter of the control rod 77 is smaller than the inner diameter of the mounting piece 75. A limiting groove 78 is provided at the top end of the split pin 71. The shape of the limiting groove 78 fits the shape of the control rod 77.
[0036] Working principle: When in use, when it is necessary to fix the first water pipe 1 and the second water pipe 2, the staff first puts the rectangular convex block of the first connector 3 into the concave convex block of the second connector 4, and then inserts the pin shaft 63 into the first connection hole 61 and the second connection hole 62.
[0037] Since the diameter of the pin shaft 63 is smaller than the inner diameter of the first connecting hole 61, it is relatively easy to insert the pin shaft 63 into the interiors of the first connecting hole 61 and the second connecting hole 62. After the insertion is completed, the staff rotates the fixing block 68, causing the fixing block 68 to drive the screw rod 67 to rotate and move forward, thereby enabling the screw rod 67 to push the sliding plate 65, so that the gas inside the air pressure chamber 64 is pushed into the interior of the airbag 69, causing the airbag 69 to expand. During the expansion process, the pin shaft 63 can be exactly at the center of the first connecting hole 61 and the second connecting hole 62 under the action of air pressure, so there is no need for manual adjustment by the staff.
[0038] After the position of the pin shaft 63 is fixed, the staff respectively insert the split pin 71 into the holes of the fixing block 68 and the mounting block 66, and make the split pin 71 pass through the fixing hole 611. After the split pin 71 is fixed, the staff first pulls up the control rod 77, causing the control rod 77 to leave the limiting groove 78 and then rotates the control rod 77, so that the control rod 77 drives the turntable 72 to rotate, and the position of the chute 73 corresponding to the horizontal position of the sliding rod 74 moves from a position close to the inside of the split pin 71 to a position close to the outside of the split pin 71. Therefore, the push plate 76 moves outwards, so the push plate 76 pushes the notched part at the bottom of the split pin 71 to expand outwards, deforming the bottom end of the split pin 71. Then, the control rod 77 is moved downwards, causing the control rod 77 to enter a new limiting groove 78. Since the bottom diameter of the deformed split pin 71 is larger than the holes formed in the inner walls of the fixing block 68 and the mounting block 66, the split pin 71 is not likely to be displaced, ensuring the fixing effect.
[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
