[0003] In the prior art, a stable device is required to achieve the connection and stability of HVAC pipes during the installation process. However, most of the stable devices have a single structure and poor functionality, and cannot keep the HVAC pipes highly tight during connection, resulting in vibration of the HVAC pipes during use, which may cause damage to the HVAC pipes and shorten their service life, thus seriously affecting the practicality of the stable device. Summary of the Utility Model

[0010] Preferably, two insertion grooves are formed on one side of the outer wall of the fixing column, and limiting rods are threadedly connected to the inner walls of the two insertion grooves.

[0011] Preferably, the bottom of the adjusting column is fixedly connected to the top of the installation plate.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] During the use of the present utility model, through the interaction of a series of components, when it is necessary to connect and fix the HVAC pipe, first, under the operation of the staff, the second installation block and the second fixing block are respectively taken out from the first installation block and the first fixing block.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1 - 4 shown, the present utility model provides a stable device for HVAC pipe connection, including an installation box 1 and an installation plate 8. A first fixing block 9 is fixedly installed on the top of the installation plate 8. The top of the first fixing block 9 is fixedly connected to a second fixing block 10 by bolts. Sealing rings 11 are provided on the outer surfaces of both the first fixing block 9 and the second fixing block 10. Two activity slots 12 are opened on the top of the installation plate 8. First installation blocks 13 are movably embedded in the inner surfaces of the two activity slots 12. Second installation blocks 14 are fixedly installed on the tops of the two first installation blocks 13 by bolts. Anti-slip pads 15 are provided on the outer surfaces of both the two first installation blocks 13 and the second installation blocks 14. A bidirectional threaded rod 16 is movably inserted between the inner surfaces of the two first installation blocks 13. A fixed box 17 is fixedly installed on one side of the outer wall of the installation plate 8. A limit spring 18 is provided on the inner surface of the fixed box 17. A limit shaft 19 is movably embedded in the inner surface of the fixed box 17, and one side of the outer wall of the limit shaft 19 is fixedly connected to one side of the outer wall of the limit spring 18.

[0024] The effect achieved by the entire Embodiment 1 is that when it is necessary to install the HVAC pipe, first, under the operation of the staff, the bolts are rotated to disassemble the second fixing block 10 and the second mounting block 14. Then, the two HVAC pipes are placed inside the notch of the first mounting block 13. Subsequently, the second mounting block 14 is placed on the top of the first mounting block 13, and the HVAC pipes are squeezed and fixed under the action of the bolts. Then, the bidirectional threaded rod 16 is rotated to drive the first mounting block 13 to move towards the middle inside the movable slot 12, thereby driving the HVAC pipes to move towards the middle, making their connection tighter. At the same time, under the action of the anti-slip pad 15, the friction of the HVAC pipes can be increased, avoiding the displacement of the HVAC pipes during use. Subsequently, under the action of the limiting spring 18 and the limiting shaft 19, the bidirectional threaded rod 16 can be limited to prevent loosening during use. Then, under the action of the first fixing block 9 and the second fixing block 10, the connection of the two HVAC pipes can be fixed, and under the action of the sealing ring 11, the tightness of the HVAC pipes can be further improved, avoiding vibration during use.

[0025] Embodiment 2: As Figures 2 - 4 shown, a fixing column 2 is movably inserted into the inner wall of the installation box 1. One side of the inner wall of the installation box 1 is fixedly installed with four buffer springs 3, and the top of the buffer spring 3 is fixedly connected to the outer wall of one side of the fixing column 2. The inner walls of the four buffer springs 3 are all provided with dampers 4. An adjusting column 5 is movably inserted into the inner wall of the fixing column 2. Two insertion slots 6 are opened on the outer wall of one side of the fixing column 2. The inner walls of the two insertion slots 6 are both threadedly connected with limiting rods 7. The bottom of the adjusting column 5 is fixedly connected to the top of the mounting plate 8.

[0026] The effect achieved by the entire Embodiment 2 is that when it is necessary to install the HVAC pipe, first, under the operation of the staff, the installation box 1 is fixed to a suitable position through bolts. Subsequently, the limiting rod 7 is taken out from the insertion slot 6. Then, the adjusting column 5 is adjusted to move to a suitable position inside the fixing column 2, and then the limiting rod 7 is inserted into the insertion slot 6. Since the outer wall of the limiting rod 7 and the inner wall of the insertion slot 6 are threadedly connected, the adjusting column 5 can be fixed and limited, thereby adjusting the installation height of the HVAC pipe. When the HVAC pipe vibrates during use after installation, under the action of the buffer spring 3 and the damper 4, the vibration generated by the HVAC pipe can be buffered, avoiding the loosening of the stabilizing device, thus greatly improving the practicality of the stabilizing device.

[0027] Working principle: When it is necessary to install and fix the HVAC pipe through the fixing device, first, under the operation of the staff, the mounting box 1 is fixed to the appropriate position by bolts. Then, the limiting rod 7 is taken out from the inside of the insertion slot 6. Then, the adjusting column 5 is adjusted to move to the appropriate position inside the fixed column 2. Next, the limiting rod 7 is inserted into the insertion slot 6 to fix and limit the adjusting column 5. When the height of the mounting plate 8 is adjusted to the appropriate position, under the operation of the staff, the bolts are rotated to disassemble the second fixing block 10 and the second mounting block 14. Then, the two HVAC pipes are placed into the notch inside the first mounting block 13. Subsequently, the second mounting block 14 is placed on the top of the first mounting block 13, and the HVAC pipes are squeezed and fixed under the action of the bolts. Then, the bidirectional threaded rod 16 is rotated to drive the first mounting block 13 to move towards the middle inside the moving slot 12, thereby driving the HVAC pipes to move towards the middle to make their connection tighter. At the same time, under the action of the anti-slip pad 15, the friction force of the HVAC pipes can be increased to prevent the HVAC pipes from shifting during use. Subsequently, under the action of the limiting spring 18 and the limiting shaft 19, the bidirectional threaded rod 16 can be limited to prevent loosening during use. Then, under the action of the first fixing block 9 and the second fixing block 10, the connection of the two HVAC pipes is fixed. When the HVAC pipes vibrate during installation and use, under the action of the buffer spring 3 and the damper 4, the vibration generated by the HVAC pipes can be buffered to prevent the fixing device from loosening, improving the practicability of the fixing device.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
