Abstract
Description
Technical Field
[0001] The present invention relates to the field of heating and ventilation equipment, in particular to a quick installation device for heating and ventilation equipment. Background Art
[0002] During the assembly and maintenance of HVAC equipment, the stable connection of heat sinks is crucial for ensuring the system's heat exchange efficiency and operational safety. Heat sinks must form a closed circuit with the piping through a reliable connection structure, preventing leakage while also withstanding the pressure shocks and temperature fluctuations experienced during system operation.
[0003] At present, the industry generally adopts the threaded connection method to achieve the fixed installation of the heat sink, that is, the heat sink is fastened to the bracket or pipe by bolts, nuts and other threaded parts. However, this traditional connection method has obvious limitations: on the one hand, the threaded parts need to be rotated multiple times during installation, which is not only time-consuming and labor-intensive, but also requires strict control of the tightening torque to avoid thread slippage or poor sealing, which increases the complexity of manual operation; on the other hand, in order to ensure the sealing performance, it is necessary to wrap sealing tape or apply sealant on the thread. This additional process not only prolongs the installation period, but may also cause the seal to fail due to improper tape winding, thereby increasing maintenance costs. In addition, during long-term use, the threaded parts are easily corroded by the medium or loosened by vibration, further reducing the reliability of the connection structure. Therefore, the present invention proposes a quick installation device for HVAC equipment to solve the above problems. Summary of the Invention

The end tubes between two adjacent heat sinks are connected by a connector. The overlapping distance between the connector and the end tubes is changed by a step-by-step structure, so that the contact ring in the end tube and the sealing ring of the connector can contact and seal.
[0007] A limiting ring structure is also movably provided on the connecting piece, and the limiting ring limits the circumferential position between itself and the end pipe by contacting the end of the end pipe.
[0008] Preferably, tubular butt joint sections are provided at both ends of the connector, and sealing rings are provided at the plug-in ends of the two butt joint sections.
[0009] Preferably, the step structure includes a wedge-shaped block arranged on the outer wall of the docking section, and the two wedge-shaped blocks are arranged in a mirror image.
[0010] Preferably, the step structure further includes a platform stage provided at the end of the end pipe, and an abutment ring in contact with the sealing ring is welded on the inner side of the end pipe.

[0015] By setting a movable ring and a plug-in section on the connector and using a nut sleeve to control the position of the movable ring, convenient positioning between the movable ring and the end pipe is achieved to improve the stability of the connector. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The following is combined with Figure 1 - Attachment Figure 4 The present invention is described in further detail.
[0022] Example 1: Reference Figure 1 - Figure 4A quick installation device for HVAC equipment, wherein end tubes 2 perpendicular to the body are provided at both ends of the heat sink 1, and the end tubes 2 between two adjacent heat sinks 1 are connected by a connector 3. The overlapping distance between the connector 3 and the end tube 2 is changed by a stage structure, so that the contact ring 21 in the end tube 2 and the sealing ring 34 of the connector 3 are in contact and sealed;
[0023] A limiting ring structure is also movably provided on the connecting piece 3 , and the limiting ring limits the circumferential position between itself and the end pipe 2 by contacting the end of the end pipe 2 .
[0024] Both ends of the connector 3 are provided with tubular butt joint sections 31 , and the plug-in ends of the two butt joint sections 31 are provided with sealing rings 34 .
[0025] The step structure includes a wedge-shaped block arranged on the outer wall of the docking section 31, and the two wedge-shaped blocks are arranged in a mirror image.
[0026] The step structure also includes a step provided at the end of the end tube 2. The inner side of the end tube 2 is welded with a contact ring 21 in contact with the sealing ring 34. Figure 3 and Figure 4 As shown, the wedge blocks include wedge block 1 32 and wedge block 2 33, and the stage includes stage 1 22 and stage 2 23. A gap 24, wider than the wedge blocks, is formed between stage 1 22 and stage 2 23. During installation, wedge block 1 32 and stage 1 22 mate, while wedge block 2 33 and stage 2 23 mate. Because they are mirror images, they move from the lower slope surface to the higher slope surface when rotated in the same direction. At this time, the connector 3 is pushed by the stepped structure into the interior of the end tube 2 of the heat sink 1, thereby increasing the sealing tightness between the contact ring 21 and the sealing ring 34, thereby ensuring the sealing between the two.
[0027] A hexagonal section 35 is provided in the middle of the connector 3, and a nut sleeve 36 is threadedly connected to one side of the hexagonal section 35. A movable ring 37 is provided between the nut sleeve 36 and the docking section 31, and a plug-in section 38 is vertically welded to the side of the movable ring 37.
[0028] A limiting groove 25 that cooperates with the plug-in end is provided in an annular array on the outer wall of the end pipe 2, and a rib is provided on the outer wall of the connector 3 to radially limit the movable ring 37. The movable ring 37 only moves axially along the connector 3. After the connector 3 is installed through the hexagonal section 35, the radial position of the hexagonal section 35 is kept stable. The nut sleeve 36 is rotated, and the nut sleeve 36 squeezes the movable ring 37 toward the side of the end pipe 2, and finally the plug-in section 38 is plugged into the limiting groove 25, completing the limitation between the connector 3 and the end pipe 2, thereby ensuring the stable position after installation.
