[0031] As Figures 1 to 5As shown, the fire sprinkler burst connecting device comprises a connecting piece 10, a lifting assembly 20 and a base 30. The first end of the lifting assembly 20 is connected with the connecting piece 10, and the second end of the lifting assembly 20 is fixed to the base 30. The connecting piece 10 is provided with a receiving cavity and an opening 101. The opening 101 is communicated with the receiving cavity and is located on the side of the connecting piece 10 away from the base 30. The opening 101 is used for passing through the sprinkler head, and the receiving cavity is used for accommodating the sprinkler head. The connecting piece 10 is connected with a connector 102 which is used for connecting the water pipe. The lifting assembly 20 can be extended, and when the lifting assembly 20 is extended, the lifting assembly 20 drives the connecting piece 10 to rise.

[0032] In the embodiment of the present application, since the first end of the lifting assembly 20 is connected with the connecting piece 10, and the second end of the lifting assembly 20 is fixed to the base 30, the lifting assembly 20 can be extended to drive the connecting piece 10 to rise, and the lifting assembly 20 can also be shortened to drive the connecting piece 10 to descend. Since the connecting piece 10 is provided with the receiving cavity and the opening 101 which is communicated with the receiving cavity and is located on the side of the connecting piece 10 away from the base 30, and the connecting piece 10 is connected with the connector 102, once the sprinkler head bursts and leaks, the water pipe can be connected to the connector 102 of the connecting piece 10, and the fire sprinkler burst connecting device can be moved to the position below the sprinkler head. Then the lifting assembly 20 is extended to drive the connecting piece 10 to rise until the sprinkler head passes through the opening 101 of the connecting piece 10 and enters the receiving cavity of the connecting piece 10, so that the water leaked from the sprinkler head can enter the connecting piece 10 and flow to the water pipe through the connector 102, thereby avoiding the water leaked from the sprinkler head from causing more damage to the objects below the sprinkler head. That is, in the embodiment of the present application, by providing the opening 101 on the connecting piece 10, connecting the connector 102 to the connecting piece 10, and connecting the lifting assembly 20 with the connecting piece 10, once the sprinkler head leaks, the connecting piece 10 can be sleeved on the sprinkler head by extending the lifting assembly 20, thereby avoiding the problem that the operator needs to carry the ladder, climb the ladder with the receiving member and specially install the receiving member on the sprinkler head, and the problem that the installation of the receiving member is complicated. That is, in the embodiment of the present application, once the sprinkler head bursts and leaks, the connecting piece 10 can be sleeved on the sprinkler head to conduct the water leaked from the sprinkler head to a suitable position.

[0033] It should be noted that in the embodiment of the present application, the connector 102 can be provided with threads, so that when the water pipe is connected to the connector 102, the water pipe can be threadedly connected with the connector 102, thereby facilitating the connection of the water pipe to the connector 102. Of course, the connector 102 can also be provided with a buckle, and when the water pipe is connected to the connector 102, the water pipe can be fixed by the buckle to be connected with the connector 102.

[0034] In addition, in the embodiments of the present application, the shape of the adapter 10 can be set according to actual needs, for example, the shape of the adapter 10 is a circular truncated cone shape, and for another example, the shape of the adapter 10 is formed by splicing two circular truncated cone shapes. The specific shape of the adapter 10 is not limited in the embodiments of the present application. Wherein, only the adapter 10 is provided with the opening 101 and has a receiving cavity.

[0035] In addition, in some embodiments, as shown in Figure 1 The lifting assembly 20 can include a support sleeve 21, a lifting rod 22, and a driving assembly 23. One end of the support sleeve 21 is fixed to the base 30, at least part of the lifting rod 22 extends into the support sleeve 21, and the end of the lifting rod 22 away from the support sleeve 21 is connected with the adapter 10. The driving assembly 23 is arranged in the support sleeve 21 and connected with the lifting rod 22. The driving assembly 23 is used to drive the lifting rod 22 to move along the axial direction of the support sleeve 21, so as to lengthen or shorten the lifting assembly 20.

[0036] Since one end of the support sleeve 21 is fixed to the base 30, at least part of the lifting rod 22 extends into the support sleeve 21, and the driving assembly 23 is arranged in the support sleeve 21 and connected with the lifting rod 22, when the lifting assembly 20 needs to be lengthened, the driving assembly 23 can be used to drive the lifting rod 22 to move along the axial direction of the support sleeve 21, so that the lifting rod 22 continuously separates from the support sleeve 21, thereby lengthening the lifting assembly 20. When the lifting assembly 20 needs to be shortened, the driving assembly 23 can also be used to drive the lifting rod 22 to move along the axial direction of the support sleeve 21, so that the lifting rod 22 continuously enters the support sleeve 21, thereby shortening the lifting assembly 20. That is, by arranging the driving assembly 23, the lifting assembly 20 can be conveniently lengthened or shortened. Once the shower head bursts and leaks, the driving assembly 23 can be used to drive the lifting rod 22 to rise, so that the adapter 10 rises, and the adapter 10 is sleeved on the shower head through the opening 101. When the lifting assembly 20 needs to be shortened, the driving assembly 23 can be used to drive the lifting rod 22 to descend, so that the adapter 10 separates from the shower head.

[0037] It should be noted that the support sleeve 21 and the base 30 can be welded, so that the support sleeve 21 is fixed to the base 30. Of course, the support sleeve 21 can also be fixed to the base 30 by other means, for example, the support sleeve 21 can also be fixed to the base 30 by locking bolts. The embodiments of the present application do not limit the fixing method of the support sleeve 21 to the base 30.

[0038] In addition, in some embodiments, as shown in Figure 1 and Figure 2As shown, the driving assembly 23 can include a rotating shaft 231 and a driving gear 232, and the lifting rod 22 is provided with a rack 221 extending along the axial direction of the support sleeve 21; the rotating shaft 231 is rotationally connected to the support sleeve 21 along the radial direction of the support sleeve 21, the driving gear 232 is sleeved on the rotating shaft 231, and the driving gear 232 is engaged with the rack 221; the rotating shaft 231 is used to drive the driving gear 232 to rotate, so that the driving gear 232 drives the lifting rod 22 to move along the axial direction of the support sleeve 21 through the rack 221.

[0039] As the lifting rod 22 is provided with the rack 221 extending along the axial direction of the support sleeve 21, the rotating shaft 231 is rotationally connected to the support sleeve 21 along the radial direction of the support sleeve 21, and the driving gear 232 is sleeved on the rotating shaft 231 and engaged with the rack 221, once the rotating shaft 231 is forced to rotate, the rotating shaft 231 can drive the driving gear 232 to rotate, so that the driving gear 232 can drive the driving rack 221 to move, and the driving rack 221 can drive the lifting rod 22 to move along the axial direction of the support sleeve 21, so that the lifting rod 22 is raised or lowered relative to the support sleeve 21, that is, the lifting assembly 20 is elongated or shortened. That is, by providing the rotating shaft 231 and the gear, and the lifting rod 22 is provided with the rack 221 engaged with the gear, the lifting rod 22 can be conveniently raised or lowered relative to the support sleeve 21, so that the lifting assembly 20 is elongated or shortened.

[0040] It should be noted that the cylinder wall of the support sleeve 21 can be provided with a rotating hole, and the rotating shaft 231 is arranged in the rotating hole, so that the rotating shaft 231 is rotationally connected to the support sleeve 21. The rotating shaft 231 can be provided with a bearing, and the bearing is located in the rotating hole, so that the rotating shaft 231 can be conveniently rotated.

[0041] In addition, the driving gear 232 and the rotating shaft 231 can be welded, of course, the driving gear 232 and the rotating shaft 231 can be interference fit, and the driving gear 232 and the rotating shaft 231 can be an integral structure.

[0042] In addition, in some embodiments, as shown in Figure 2 As shown, one end of the rotating shaft 231 is connected with a rotating handle 233, the rotating handle 233 is located outside the support sleeve 21, and the rotating handle 233 is used to drive the rotating shaft 231 to rotate, so that the rotating shaft 231 drives the driving gear 232 to rotate.

[0043] Since one end of the rotating shaft 231 is connected with the rotating handle 233, an operator can hold the rotating handle 233 to apply force to the rotating handle 233, so that the handle drives the rotating shaft 231 to rotate, and the rotating shaft 231 drives the driving gear 232 to rotate. That is, by connecting the rotating handle 233 at one end of the rotating shaft 231, when the shower head bursts, the operator can hold the handle to make the rotating shaft 231 rotate, and the rotating shaft 231 drives the driving gear 232 to rotate, so that the lifting rod 22 rises relative to the support sleeve, and the lifting rod 22 drives the connecting piece 10 to rise. That is, by providing the rotating handle 233, the operator can be facilitated to operate, and the lifting rod 22 drives the connecting piece 10 to be sleeved on the shower head.

[0044] It should be noted that the shape of the rotating handle 233 can be set according to actual needs, for example, the rotating handle 233 is Z-shaped, and for another example, the rotating handle 233 is L-shaped. The specific shape of the rotating handle 233 is not limited herein by the embodiments of the present application.

[0045] In addition, one end of the rotating shaft 231 can be welded to the rotating handle 233, of course, one end of the rotating shaft 231 can also be connected to the rotating handle 233 through a pin. For this, the embodiments of the present application are not limited herein.

[0046] In addition, in the embodiments of the present application, the operator can hold the rotating handle 233 to make the rotating handle 233 rotate in a first rotation direction, so that the rotating shaft 231 rotates, and the driving gear 232 rotates with the rotating shaft 231, the driving gear 232 drives the rack 221 to move, so that the lifting rod 22 rises; the operator can also hold the rotating handle 233 to make the rotating handle 233 rotate in a second rotation direction, so that the rotating shaft 231 rotates, and the driving gear 232 rotates with the rotating shaft 231, the driving gear 232 drives the rack 221 to move, so that the lifting rod 22 descends. Wherein, the first rotation direction is opposite to the second rotation direction.

[0047] In addition, in some embodiments, as shown in Figure 3 and Figure 4 one end of the rotating shaft 231 is connected with a driving motor 234, the driving motor 234 is located outside the support sleeve 21, and the driving motor 234 is used to drive the rotating shaft 231 to rotate, so that the rotating shaft 231 drives the driving gear 232 to rotate.

[0048] Since one end of the rotating shaft 231 is connected with the driving motor 234, the driving motor 234 can be rotated, so that the driving motor 234 drives the rotating shaft 231 to rotate, and the rotating shaft 231 drives the driving gear 232 to rotate. That is, by connecting the driving motor 234 at one end of the rotating shaft 231, when the spray head bursts, the driving motor 234 can be operated to drive the rotating shaft 231 to rotate, and the rotating shaft 231 drives the driving gear 232 to rotate, so that the lifting rod 22 rises relative to the support sleeve, and the lifting rod 22 drives the connecting piece 10 to rise. That is, by arranging the driving motor 234, the lifting rod 22 can conveniently drive the connecting piece 10 to be sleeved on the spray head, and the labor intensity of the operator can be reduced.

[0049] It should be noted that the output shaft of the driving motor 234 is connected with a speed reduction assembly, the speed reduction assembly is connected with one end of the rotating shaft 231, and the speed reduction assembly can reduce the high rotating speed of the driving motor 234, so that the rotating shaft 231 rotates at a lower speed.

[0050] Of course, in the embodiment of the application, the driving assembly 23 can be a pneumatic cylinder, which is located in the support sleeve 21, and the pneumatic cylinder includes a cylinder body and a piston, and the piston is connected with the lifting rod 22, so that when the piston moves, the lifting rod 22 rises or falls relative to the support sleeve 21.

[0051] In addition, in some embodiments, as shown in Figure 5 The fire-fighting spray burst connecting device can further include a waterproof shell 235, and the waterproof shell 235 is connected to the support sleeve 21, and the driving motor 234 is located in the waterproof shell 235.

[0052] Since the waterproof shell 235 is connected to the support sleeve 21, and the driving motor 234 is located in the waterproof shell 235, the waterproof shell 235 can effectively protect the driving motor 234, so that the water sprayed by the spray head does not come into contact with the driving motor 234, thereby avoiding the problem that the driving motor 234 may be short-circuited or malfunction. That is, by arranging the waterproof shell 235, the driving motor 234 can be protected, so that the service life of the fire-fighting spray burst connecting device is prolonged.

[0053] It should be noted that the waterproof shell 235 can be connected to the support sleeve 21 by bolts. In addition, the waterproof shell 235 can be made of plastic to avoid the problem that the waterproof shell 235 may rust after being in contact with water. Of course, the waterproof shell 235 can also be made of a material, for example, a waterproof shell alloy. The specific material of the waterproof shell 235 is not limited in the embodiment of the application.

[0055] Since the battery is electrically connected with the driving motor 234, the battery can supply power to the driving motor 234, so that the driving motor 234 operates, thereby driving the rotation shaft 231 to rotate, and the presence of the battery can ensure the long-time operation of the driving motor 234.

[0056] It should be noted that in the embodiment of the present application, the battery can be taken out of the waterproof shell 235 to charge the battery. Of course, the waterproof shell 235 can be provided with a charging interface, the charging interface is electrically connected with the battery, and the battery can be charged through the charging interface. In addition, the waterproof shell 235 can be provided with a prompt lamp, the prompt lamp is electrically connected with the battery, and the prompt lamp is used to indicate the power of the battery, for example, when the power of the battery is greater than 20%, the prompt lamp emits green light, and when the power of the battery is less than or equal to 20%, the prompt lamp emits red light.

[0057] In addition, in some embodiments, as shown in Figure 5 the outer wall of the waterproof shell 235 is provided with a control button 236, the control button 236 is electrically connected with the driving motor 234, and the control button 236 is used to control the driving motor 234 to operate or stop. By setting the control button 236, the operator can send instructions to the driving motor 234 by pressing the control button 236, so as to control the driving motor 234, so that the driving motor 234 operates, and then the lifting rod 22 rises or falls, and the lifting rod 22 can be raised to the appropriate position to make the driving motor 234 stop operating, or the lifting rod 22 can be lowered to the appropriate position to make the driving motor 234 stop operating. That is, by setting the control button 236, the operator can control the driving motor 234 to control the lifting rod 22 to rise or fall.

[0058] It should be noted that the number of control buttons 236 can be set according to actual needs, for example, the number of control buttons 236 is three, when the first control button 236 is pressed, the driving motor 234 drives the rotation shaft 231 to rotate, so that the lifting rod 22 rises relative to the support sleeve 21, when the second control button 236 is pressed, the driving motor 234 drives the rotation shaft 231 to rotate, so that the lifting rod 22 falls relative to the support sleeve 21; when the third control button 236 is pressed, the driving motor 234 stops operating, so that the rotation shaft 231 stops rotating; for example, the number of control buttons 236 is one, when the control button 236 is pressed once, the driving motor 234 drives the rotation shaft 231 to rotate, so that the lifting rod 22 rises relative to the support sleeve 21, when the control button 236 is pressed twice in succession, the driving motor 234 drives the rotation shaft 231 to rotate, so that the lifting rod 22 falls relative to the support sleeve 21. The specific number of control buttons 236 is not limited in the embodiment of the present application.

[0059] In addition, in the embodiment of the present application, the waterproof shell 235 is provided with a control circuit board, which is electrically connected with the control button 236 and the driving motor 234 respectively, so that when the operator presses the control button 236, the control button 236 sends an instruction to the control circuit board, and the control circuit board controls the driving motor 234. The control circuit board can be a printed circuit board (PCB), and of course, the control circuit board can also be a flexible printed circuit (FPC).

[0060] In addition, in some embodiments, as shown in Figure 1 The fire sprinkler burst connection device can further include an upper cover 40, which is detachably connected to the opening 101 of the connection piece 10.

[0061] Since the upper cover 40 is detachably connected to the opening 101 of the connection piece 10, when it is necessary to extend the sprinkler head into the connection piece 10 through the opening 101, the upper cover 40 can be separated from the opening 101, so that the sprinkler head can enter the connection piece 10. When the sprinkler head does not need to extend into the connection piece 10, the upper cover 40 can be covered on the opening 101 of the connection piece 10, so that impurities can be prevented from entering the connection piece 10, and the problem that the joint 102 can be blocked by impurities can be avoided.

[0062] In addition, in some embodiments, the bottom base 30 is connected with a plurality of rollers 50 on the side away from the lifting assembly 20, and the rollers 50 are used to drive the bottom base 30 to move.
