DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0029] A fixed pump pipe sealing structure, such as Figure 1-Figure 8 As shown, it includes a closed structure installed at the end of the pump tube 1, and the closed structure includes a first fixing ring 2 and a second fixing ring 3. The first fixing ring 2 and the second fixing ring 3 are both semicircular structures with the same diameter. One end of the first fixing ring 2 and the second fixing ring 3 are rotatably connected by a hinge 4, and the other end is respectively fixedly connected with a first fixing block 6 or a second fixing block 7. The first fixing block 6 and the second fixing block 7 are connected so that the first fixing ring 2 and the second fixing ring 3 form a closed circular ring to be clamped at one end of the pump tube 1.

[0030] Through the above technical scheme, the two parts of the hinge 4 in the utility model are respectively fixedly installed on one end of the first fixing ring 2 and the second fixing ring 3, and the rotation connection of the first fixing ring 2 and the second fixing ring 3 is realized by rotating the two parts of the hinge 4; the first fixing ring 2 and the second fixing ring 3 are both semicircular structures and have the same diameter, so when the other ends of the first fixing ring 2 and the second fixing ring 3 are in contact, a closed circular ring can be formed, and the first fixing ring 2 and the second fixing ring 3 can be clamped on one end of the pump tube 1; the first fixing block 6 and the second fixing block 7 are respectively fixedly installed on the other ends of the first fixing ring 2 and the second fixing ring 3, and the connection of the other ends of the first fixing ring 2 and the second fixing ring 3 can be realized by connecting the first fixing block 6 and the second fixing block 7.

[0031] like Figure 1-Figure 8 As shown, in this embodiment: the first fixing ring 2 and the second fixing ring 3 are respectively provided with a first clamping groove 21 and a second clamping groove 31 on their sides, both of which are semicircular structures and have the same diameter; a baffle 5 is welded in the first clamping groove 21 or the second clamping groove 31, and the baffle 5 blocks one end of the pump tube 1 to prevent foreign objects from being discarded artificially, and the first clamping groove 21 and the second clamping groove 31 together form an annular frame, and the baffle 5 matches the annular frame and has a diameter larger than the inner diameter port of the pump tube 1, and the thickness of the baffle 5 is less than the thickness of the annular frame to prevent foreign objects from being discarded artificially.

[0032] Through the above technical scheme, the baffle plate 5 in the utility model is welded in the first clamping groove 21 or the second clamping groove 31. When the second clamping groove 31 or the first clamping groove 21 forms an annular frame with the first clamping groove 21 or the second clamping groove 31, the baffle plate 5 can be clamped; the diameter of the baffle plate 5 is larger than the inner diameter port of the pump tube 1, so as to achieve the purpose of blocking the inner cavity of the pump tube 1; the thickness of the baffle plate 5 is smaller than the thickness of the annular frame, and the protruding part of the annular frame relative to the baffle plate 5 is sleeved on the outer diameter of the pump tube 1, so as to achieve the purpose of the first fixing ring 2 and the second fixing ring 3 clamping the end of the pump tube 1.

[0033] like Figure 1-Figure 8 As shown, in this embodiment: the first fixing block 6 is taller than the second fixing block 7 .

[0034] Through the above technical solution, when the first fixed block 6 and the second fixed block 7 are difficult to separate due to the concrete attached during the construction process, the purpose of separating the first fixed block 6 and the second fixed block 7 can be achieved by knocking the part of the first fixed block 6 that is higher than the second fixed block 7.

[0035] The process of the first fixing ring 2 and the second fixing ring 3 clamping the pump tube 1 is as follows:

[0036] First, the first clamping groove 21 or the second clamping groove 31 welded with the baffle 5 is sleeved on the outer diameter of the pump tube 1, so that the baffle 5 is close to the end face of the pump tube 1, and then, the first fixing block 6 or the second fixing block 7 is used to drive the first fixing ring 2 or the second fixing ring 3 to rotate until the first clamping groove 21 or the second clamping groove 31 is sleeved on the outer diameter of the pump tube 1, and the baffle 5 completely enters the first clamping groove 21 or the second clamping groove 31, and then, the first fixing block 6 and the second fixing block 7 are fixedly connected, so that the first fixing ring 2 and the second fixing ring 3 can clamp the pump tube 1, and the baffle 5 blocks the pipe opening of the pump tube 1;

[0037] When the first fixing block 6 and the second fixing block 7 are separated, the first fixing ring 2 and the second fixing ring 3 release the clamping of the pump tube 1 , and the baffle 5 releases the blocking of the pipe opening of the pump tube 1 .

[0038] like Figure 1-Figure 8 As shown, in this embodiment: a locking mechanism 8 is provided in the first fixing block 6 , a plug-in mechanism 9 is provided in the second fixing block 7 , and the first fixing block 6 and the second fixing block 7 are fixedly connected via the locking mechanism 8 and the plug-in mechanism 9 .

[0039] Through the above technical solution, the locking mechanism 8 and the plug-in mechanism 9 in the utility model can realize the fixed connection between the first fixing block 6 and the second fixing block 7 .

[0040] like Figure 1-Figure 8As shown, in this embodiment: a sliding cavity 71 is opened in the second fixed block 7, and the extension direction of the sliding cavity 71 is perpendicular to the side of the first fixed block 6. The plug-in mechanism 9 includes a plug-in rod 91 and a handle 95. The plug-in rod 91 is slidably connected in the sliding cavity 71. The handle 95 is fixedly installed at the end of the plug-in rod 91 and drives the plug-in rod 91 to be inserted into the plug-in cavity 61. The width of the handle 95 is greater than the plug-in rod 91 and is located outside the second fixed block 7. The plug-in cavity 61 is opened on the first fixed block 6. The locking mechanism 8 fixes the plug-in rod 91 inserted into the plug-in cavity 61 to achieve a fixed connection between the first fixed block 6 and the second fixed block 7.

[0041] Through the above technical scheme, the extension direction of the sliding cavity 71 in the utility model is perpendicular to the side of the first fixed block 6, which is convenient for the plug-in rod 91 to be vertically inserted into the plug-in cavity 61 without any jamming; the handle 95 can drive the plug-in rod 91 to extend and retract along the sliding cavity 71; the width of the handle 95 is greater than the plug-in rod 91, which can prevent the handle 95 from entering the sliding cavity 71.

[0042] like Figure 1-Figure 8 As shown, in this embodiment: a first inclined surface 82 is provided at the free end of the locking rod 81, and a second inclined surface 92 with the same inclination angle as the first inclined surface 82 is provided at the free end of the plug-in rod 91. The plug-in rod 91 is connected by sliding connection between the first inclined surface 82 and the second inclined surface 92, thereby driving the locking rod 81 to slide along the lifting chamber 62.

[0043] Through the above technical scheme, during the process of inserting the plug-in rod 91 into the plug-in cavity 61 in the utility model, the plug-in rod 91 can drive the locking rod 81 to rise along the lifting cavity 62 through the sliding connection between the first inclined surface 82 and the second inclined surface 92, thereby preventing the locking rod 81 from obstructing the plug-in rod 91 from entering the plug-in cavity 61.

[0044] like Figure 1-Figure 8 As shown, in this embodiment: a lifting cavity 62 is provided in the second fixed block 7 and is vertically connected to the plug-in cavity 61. The lifting cavity 62 passes through the second fixed block 7. The locking mechanism 8 includes a locking rod 81 and a handle 84. The locking rod 81 is slidably connected in the lifting cavity 62 and extends into the plug-in cavity 61. The handle 84 is fixedly installed on the top of the locking rod 81 and is used to drive the locking rod 81. The width of the handle 84 is greater than that of the locking rod 81 and is located outside the first fixed block 6; a locking groove 93 is provided on the plug-in rod 91, and the locking rod 81 is inserted into the locking groove 93 to fix the position of the plug-in rod 91.

[0045] Through the above technical scheme, after the plug-in rod 91 in the utility model is fully inserted into the plug-in cavity 61, the locking rod 81 is inserted downward into the locking groove 93 due to the action of gravity to fix the position of the plug-in rod 91; the handle 84 can drive the locking rod 81 to slide along the lifting cavity 62; the width of the handle 84 is greater than the locking rod 81, which can prevent the handle 84 from entering the lifting cavity 62.

[0046] like Figure 1-Figure 8 As shown, in this embodiment: a first limit groove 63 is opened on both sides of the lifting cavity 62, a first limit block 83 is provided on both sides of the locking rod 81, and the first limit block 83 is slidably connected in the first limit groove 63; a second limit groove 72 is opened on both sides of the sliding cavity 71, a second limit block 94 is provided on both sides of the plug-in rod 91, and the second limit block 94 is slidably connected in the second limit groove 72.

[0047] Through the above technical scheme, the first limit block 83 in the utility model slides along the first limit groove 63, which can limit the sliding range of the locking rod 81 and prevent the locking rod 81 from being separated from the lifting chamber 62; the second limit block 94 slides along the second limit groove 72, which can limit the sliding range of the plug-in rod 91 and prevent the plug-in rod 91 from being separated from the sliding chamber 71.

[0048] The working process of the locking mechanism 8 and the plug-in mechanism 9 is as follows:

[0049] When the first fixed block 6 and the second fixed block 7 are in contact, first, the plug-in rod 91 is driven by the handle 95 to slide along the sliding cavity 71, so that the free end of the plug-in rod 91 is inserted into the plug-in cavity 61. When the plug-in rod 91 contacts the locking rod 81, the first inclined surface 82 and the second inclined surface 92 slide relative to each other, and the plug-in rod 91 drives the locking rod 81 to rise along the lifting cavity 62 until the locking rod 81 completely enters the lifting cavity 62. Then, the plug-in rod 91 continues to be inserted into the plug-in cavity 61 until it completely enters the plug-in cavity 61. At this time, the free end of the locking rod 81 is just above the locking groove 93. Under the action of gravity, the locking rod 81 is inserted into the locking groove 93 to fix the position of the plug-in rod 91, so as to realize the fixed connection between the first fixed block 6 and the second fixed block 7.

[0050] When it is necessary to separate the first fixing block 6 and the second fixing block 7, it is only necessary to lift up the locking rod 81 through the handle 84 so that the locking rod 81 disengages from the locking groove 93, and then, pull the plug-in rod 91 out of the plug-in cavity 61 through the handle 95 to achieve the separation of the first fixing block 6 and the second fixing block 7.

[0051] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
