[0023] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] See also Figure 1-Figure 2 , Figure 1 It is a schematic diagram of the three-dimensional structure of the holder provided by the embodiment of the utility model; Figure 2 Schematic diagram of the exploded structure of the shroud clamp provided by the embodiment of the utility model. The utility model provides a shroud clamp 1 for a holder, which is used to be installed on a holder 2. The shroud clamp 1 includes a clamp body 11, a first rotating member 12 and a second rotating member 13. The first rotating member 12 is rotatably connected to the clamp body 11. The second rotating member 13 is sleeved in the first rotating member 12 and rotatably connected to the first rotating member 12. The inner diameter of the second rotating member 13 is adapted to the outer diameter of the shroud 4 so that the shroud 4 can be plugged in.

[0025] By arranging a first rotating member 12 for rotational connection on the clamp body 11, the second rotating member 13 is sleeved in the first rotating member 12, and the second rotating member 13 is rotationally connected to the first rotating member 12, and then after the long nozzle 4 is inserted into the second rotating member 13, the long nozzle 4 can be swung relative to the clamp body 11 under the rotational connection between the first rotating member 12 and the clamp body 11, and can be swung relative to the first rotating member 12 under the rotational connection between the second rotating member 13 and the first rotating member 12, so that when the long nozzle 4 is installed to the water tank, the long nozzle 4 can be swung relative to the first rotating member 12. When the long water spout 4 is on the outlet, the long water spout clamp 1 is installed on the holder 2, and the long water spout 4 is inserted into the long water spout clamp 1, and the holder 2 can drive the clamp body 11 to connect the long water spout 4 and move together. When the holder 2 drives the long water spout 4 to connect and install with the outlet, the long water spout 4 is squeezed in the direction of the outlet, so that the long water spout 4 swings under the rotation of the first rotating part 12 and the second rotating part 13, so as to eliminate the error when the long water spout 4 and the outlet are installed under the swing of the long water spout 4, thereby facilitating the installation of the long water spout 4 on the outlet.

[0026] Compared with the existing method of installing the long water spout 4 with the holder 2, the long water spout clamp 1 of the holder of the utility model can allow the down spout to swing relative to the clamp body 11 when the down spout is installed, thereby eliminating the installation error when the long water spout 4 and the down spout are docked and installed. There is no need to control the holder 2 to drive the long water spout 4 to move precisely, thereby reducing the installation difficulty of the long water spout 4 and improving the installation efficiency of the long water spout 4.

[0027] In the embodiment of the present invention, the first rotating member 12 is rotatably connected to the clamp body 11 and can rotate along a first direction, and the second rotating member 13 is rotatably connected to the first rotating member 12 and can rotate along a second direction. The first direction and the second direction are perpendicular to each other.

[0028] Since the first rotating member 12 can rotate relative to the clamp body 11 in the first direction, and the second rotating member 13 can rotate relative to the first rotating member 12 in the second direction, after the long water nozzle 4 is inserted into the second rotating member 13, the long water nozzle 4 can swing in the first direction and the second direction. Since the first direction is perpendicular to the second direction, the long water nozzle 4 can rotate 360° relative to the clamp body 11 at any angle, thereby eliminating the error during the installation of the long water nozzle 4 and reducing the difficulty of installing the long water nozzle 4.

[0029] See also Figure 2The first rotating member 12 rotates relative to the clamp body 11 in the first direction, that is, the first rotating member 12 rotates relative to the clamp body 11 in the X-axis direction in the figure. Similarly, the second rotating member 13 rotates relative to the first rotating member 12 in the second direction, that is, the second rotating member 13 rotates relative to the first rotating member 12 in the Y-axis direction in the figure. Since the X-axis and the Y-axis are perpendicular to each other, after the long water nozzle 4 is inserted into the second rotating member 13, the long water nozzle 4 can rotate around the X-axis and the Y-axis at the same time to swing, thereby adjusting the installation error when the long water nozzle 4 is connected to the lower water nozzle, thereby reducing the difficulty of installing the long water nozzle 4.

[0030] In the embodiment of the utility model, the long shroud clamp 1 includes a first pin shaft 14 and a second pin shaft 15 , the first rotating member 12 is rotatably connected to the clamp body 11 via the first pin shaft 14 , and the second rotating member 13 is rotatably connected to the first rotating member 12 via the second pin shaft 15 .

[0031] By passing the first pin 14 through the clamp body 11 and connecting the first pin 14 to the first rotating member 12, the first rotating member 12 can be rotated relative to the clamp body 11 under the connection with the first pin 14, that is, the first rotating member 12 rotates relative to the clamp body 11 around the first pin 14, and by passing the second pin 15 through the first rotating member 12 and connecting the second pin 15 to the second rotating member 13, the second rotating member 13 can be rotated relative to the first rotating member 12 under the connection with the second pin 15, that is, the second rotating member 13 rotates relative to the first rotating member 12 around the second pin 15, and then the long water nozzle 4 can swing around the first pin 14 and the second pin 15 when the long water nozzle 4 is installed, thereby eliminating installation errors and improving the installation efficiency of the long water nozzle 4.

[0032] In other embodiments of the utility model, a protruding first rotating shaft is provided on the first rotating member 12, and the first rotating member 12 is rotatably connected to the clamp body 11 through the first rotating shaft. Similarly, a protruding second rotating shaft is provided on the second rotating member 13, and the second rotating member 13 is rotatably connected to the first rotating member 12 through the second rotating shaft. After the long water spout 4 is inserted into the second rotating member 13, the long water spout 4 can rotate around the first rotating shaft and around the second rotating shaft under the action of the first rotating member 12 and the second rotating member 13, so that the long water spout 4 can swing at any angle of 360° relative to the clamp body 11, so as to eliminate installation errors during the installation of the long water spout 4, reduce the difficulty of installing the long water spout 4, and improve the installation efficiency of the long water spout 4.

[0033] In an embodiment of the utility model, the clamp body 11 includes a connecting column 111 and a U-shaped connecting plate 112 , the connecting plate 112 is fixedly connected to one end of the connecting column 111 , and the first rotating member 12 is located at the U-shaped opening of the connecting plate 112 and is rotatably connected to the connecting plate 112 .

[0034] By setting a U-shaped connecting plate 112 and fixing it with the connecting column 111, the long water nozzle clamp 1 can be connected to the holder 2 through the connecting column 111, and then the long water nozzle clamp 1 can be driven to move under the control of the holder 2, so that the holder 2 can drive the long water nozzle clamp 1 to install the long water nozzle 4. The first rotating member 12 is located at the U-shaped opening of the connecting plate 112 and is rotatably connected to the connecting plate 112 through the first pin shaft 14, so that the first rotating member 12 can be rotated in the U-shaped opening of the connecting plate 112 under the rotation connection of the first pin shaft 14, thereby preventing the connecting plate 112 from interfering with the rotation of the first rotating member 12, thereby limiting the rotation angle of the first rotating member 12.

[0035] In an embodiment of the utility model, a reinforcing rib plate 113 is provided between the connecting column 111 and the connecting plate 112, so as to improve the connection firmness between the connecting plate 112 and the connecting column 111 and increase the overall structural strength of the clamp body 11, so that the clamp body 11 can withstand greater force when clamping the long water outlet 4 for installation.

[0036] In an embodiment of the utility model, reinforcing ribs 113 fixedly connected to the connecting plate 112 are welded on the connecting column 111 in the four directions of up, down, left and right. Thus, the reinforcing ribs 113 can evenly support the connecting plate 112 in the circumferential direction of the connecting column 111, so as to increase the structural strength between the connecting plate 112 and the connecting column 111, and facilitate the clamp body 11 to clamp the long water outlet 4 for installation.

[0037] In an embodiment of the utility model, the long water outlet clamp 1 also includes a first quick changer 16 and a second quick changer 17, a flange 1111 is provided at one end of the connecting column 111 away from the connecting plate 112, the first quick changer 16 is fixedly connected to the flange 1111, the second quick changer 17 is fixed on the holder 2, and the long water outlet clamp 1 is connected to the holder 2 via the first quick changer 16 and the second quick changer 17.

[0038] By setting a flange 1111 at one end of the connecting column 111 away from the connecting plate 112, fixing the first quick changer 16 on the flange 1111, and fixing the second quick changer 17 on the holder 2, the long water nozzle clamp 1 can be fixed on the holder 2 through the connection between the first quick changer 16 and the second quick changer 17, so that the holder 2 can drive the long water nozzle clamp 1 to install the long water nozzle 4. After the installation of the long water nozzle 4 is completed, the connection between the first quick changer 16 and the second quick changer 17 can be released, so that the long water nozzle clamp 1 can be removed from the holder 2, so as to reduce the space occupied by the holder 2 at the work site and facilitate the activities of the operators at the work site.

[0039] In the embodiment of the present utility model, the connection mode between the first quick changer 16 and the second quick changer 17 includes any one of expansion clamping and buckle clamping.

[0040] By setting the connection mode of the first quick changer 16 and the second quick changer 17 to any one of expansion snap connection and snap connection, the first quick changer 16 and the second quick changer 17 can be connected or disassembled more quickly, thereby improving the disassembly and assembly efficiency of the long nozzle clamp 1 and the holder 2.

[0041] In one embodiment of the utility model, the first quick changer 16 and the second quick changer 17 are expanded and snap-fitted, that is, the first quick changer 16 is a quick-change male disk in the quick-change disk, and the second quick changer 17 is a quick-change female disk in the quick-change disk. After the quick-change male disk and the quick-change female disk are docked, the quick-change male disk is ventilated so that the piston in the quick-change male disk is inserted into the quick-change female disk and expands, thereby realizing the expansion snap-fitting of the quick-change male disk and the quick-change female disk, thereby improving the connection efficiency between the long water outlet clamp 1 and the holder 2. During disassembly, the quick-change male disk is depressurized so that the piston shrinks and withdraws from the quick-change female disk, thereby the quick-change male disk can be removed from the quick-change female disk, thereby improving the disassembly efficiency of the long water outlet clamp 1 and the holder 2.

[0042] In the embodiment of the utility model, the long shroud fixture 1 further includes a purge pipe 18 , one end of the purge pipe 18 is connected to an external air source, and the other end of the purge pipe 18 faces the second rotating member 13 .

[0043] By connecting one end of the purge pipe 18 to the external air source and the other end facing the second rotating part 13, the purge pipe 18 can blow air to the second rotating part 13 after the external air source is ventilated to blow off the iron filings and debris in the second rotating part 13, making it easier to insert the long water nozzle 4 into the second rotating part 13. When installing the long water nozzle 4, the purge pipe 18 blows air to the second rotating part 13, so as to blow away the liquid metal seeping from the lower water nozzle, preventing the liquid metal from falling onto the long water nozzle 4 and affecting the docking installation of the long water nozzle 4 and the lower water nozzle, thereby reducing the difficulty of installing the long water nozzle 4.

[0044] In an embodiment of the utility model, the purge pipe 18 is installed inside the connecting column 111 and passes through the connecting plate 112; or the outer surface of the connecting column 111 is provided with a plug-in tube 1112 for plugging the purge pipe 18, and the purge pipe 18 is connected to the external air source through the plug-in tube 1112.

[0045] In one embodiment of the utility model, the outer surface of the connecting column 111 is provided with a plug-in tube 1112 connected to an external gas source. One end of the purge tube 18 is connected to the external gas source by being plugged into the plug-in tube 1112, and the other end is facing the second connecting piece. After the external gas source is ventilated, the gas passes through the plug-in tube 1112 and is blown out from one end of the purge tube 18, thereby achieving the purging of the second connecting piece.

[0046] In other embodiments of the utility model, the purge pipe 18 is installed inside the connecting column 111 and then passes through the connecting plate 112, so as to ensure that the purge pipe 18 can purge the second connecting piece while protecting the purge pipe 18 under the action of the connecting column 111 to prevent the purge pipe 18 from contacting with external objects and damaging the purge pipe 18 when the long water outlet clamp 1 moves.

[0047] In an embodiment of the utility model, the external gas source includes any one of an argon gas source, a nitrogen gas source, and an air gas source, so that the purge pipe 18 blows out the corresponding gas to the second connecting piece, thereby removing iron filings and debris on the surface of the second connecting piece, making it convenient for the long water nozzle 4 to be plugged in with the second connecting piece. When the long water nozzle 4 is installed, the surface of the long water nozzle 4 can be purged to remove iron filings and debris on the surface of the long water nozzle 4, making it convenient for the long water nozzle 4 to be connected and installed with the lower water nozzle.

[0048] According to the above-mentioned shroud clamp 1 , an embodiment of the utility model further provides a shroud holder 2 , which comprises a holder body 21 and the above-mentioned shroud clamp 1 , and the shroud clamp 1 is detachably connected to the holder body 21 .

[0049] By connecting the shroud fixture 1 to the holder body 21, the shroud fixture 1 can be driven to move by controlling the holder body 21 and the shroud 4 can be installed. During the installation, the shroud 4 is inserted into the second rotating member 13 so that the shroud 4 can swing relative to the fixture body 11 under the rotational connection between the first rotating member 12 and the fixture body 11, and swing relative to the first rotating member 12 under the rotational connection between the second rotating member 13 and the first rotating member 12, and then the fixture body 11 is driven by the holder body 21. The connected long water spout 4 moves together, and when the holder body 21 drives the long water spout 4 to connect and install with the downspout, the long water spout 4 is squeezed in the direction of the downspout, so that the long water spout 4 swings under the rotation of the first rotating member 12 and the second rotating member 13, so as to eliminate the error when the long water spout 4 and the downspout are installed under the swing of the long water spout 4, and then it is convenient to install the long water spout 4 on the downspout, without controlling the holder body 21 to drive the long water spout 4 to move accurately, thereby reducing the difficulty of installing the long water spout 4 and improving the installation efficiency of the long water spout 4.
