The two tempered glasses are fixed to the upper portion of the aluminum profile, and a vacuum cavity is formed between the two tempered glasses. A connecting sleeve is fixedly inserted at a position in the vacuum cavity on the upper portion of the aluminum profile. The connecting sleeve connects the vacuum cavity with the interior of the aluminum profile, and a sealing component is provided in the connecting sleeve. Both sides of the interior of the aluminum profile form a heat-insulating cold bridge through a frame. A mounting port is provided on one side of the bottom of the aluminum profile, and the mounting tube can be installed by The mounting tube is inserted into the mouth, and a fixed connecting piece is provided between the mounting tube and the aluminum profile. The upper end of the mounting tube is an open structure, and a porous sleeve is coaxially fixed to the bottom wall of the inner part of the mounting tube. An annular space is formed between the outer wall of the porous sleeve and the inner wall of the mounting tube. The annular space is filled with dry particles. An air nozzle groove is coaxially opened at one end of the mounting tube, and an air exhaust nozzle is installed in the air nozzle groove. An end cover is threadedly connected to the open end of the mounting tube, and a through groove is opened in the middle of the end cover.

[0007] Preferably, the fixed connection member includes an end plate fixedly mounted on the lower end of the mounting tube, and mounting holes are provided at both ends of the end plate. Two threaded holes are provided at the bottom of the aluminum profile, and the end plate is fixed to the aluminum profile through the mounting holes, threaded holes and screws.

[0008] Furthermore, blocks are fixed to the lower ends of the outer walls on both sides of the installation tube, and notches are opened on the inner walls on both sides of the installation opening. The blocks are adapted to the notches, and the threaded holes and the installation holes are staggered.

[0009] Preferably, a one-way valve is installed on the bottom wall of the installation cylinder near the air extraction nozzle.

[0010] Furthermore, a connecting frame is fixed in the through slot, and one end of the ejector pin is fixed to the upper part of the connecting frame.

[0011] As a further solution of the present invention, a sealing groove is provided on the upper portion of the end cover, and the sealing groove and the through groove are provided coaxially.

[0013] The beneficial effects of the present invention are:

[0014] 1. The present invention provides a mounting tube and a porous sleeve provided in the mounting tube, and drying particles are provided in the annular space formed between the porous sleeve and the mounting tube. When the mounting tube is installed in place, the ejector pin pushes open the sealing plug, so that the vacuum chamber is now connected with the mounting tube. When mist and water droplets appear in the vacuum chamber, the drying particles can continuously and effectively absorb them, thereby avoiding water accumulation after the formation of water mist inside and maintaining internal dryness.

[0015] 2. The present invention provides an end cap at one end of the mounting tube in combination with an air extraction nozzle and a one-way valve, so that when we replace the dry particles, we can remove the screws at both ends of the end plate and pull out the mounting tube. When pulling it out, the ejector pin at the upper end of the mounting tube is separated from the sealing plug, so that the sealing plug automatically cooperates with the sealing ring under the action of the spring rod to seal the connecting sleeve, thereby preventing air from entering the vacuum chamber. Then, the end cap can be unscrewed, the dry particles in the annular space can be taken out and new particles can be filled in. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Reference Figure 1-6A multi-cavity aluminum alloy profile for heat-insulating cold bridges for system doors and windows comprises an aluminum profile 1, a mounting tube 3 and two tempered glasses 2. The two tempered glasses 2 are fixed to the upper part of the aluminum profile 1, and a vacuum cavity 7 is formed between the two tempered glasses 2. A connecting sleeve 6 is fixedly inserted at a position in the vacuum cavity 7 on the upper part of the aluminum profile 1. The connecting sleeve 6 connects the vacuum cavity 7 with the interior of the aluminum profile 1, and a sealing component is provided in the connecting sleeve 6. Both sides of the interior of the aluminum profile 1 are formed with a heat-insulating cold bridge 18 through a frame. A mounting port is provided on one side of the bottom of the aluminum profile 1, and the mounting tube 3 can be inserted through the mounting port. A fixed connecting sleeve 6 is provided between the mounting tube 3 and the aluminum profile 1. The connecting part, the upper end of the mounting cylinder 3 is an open structure, and a porous sleeve 16 is coaxially fixed to the bottom wall of the inner part of the mounting cylinder 3, and an annular space 15 is formed between the outer wall of the porous sleeve 16 and the inner wall of the mounting cylinder 3. The annular space 15 is filled with dry particles, and the dry particles can continuously and effectively absorb the water mist in the vacuum chamber 7 in a timely manner to maintain internal dryness. An air nozzle groove is coaxially opened at one end of the mounting cylinder 3, and an air exhaust nozzle is installed in the air nozzle groove. The open end of the mounting cylinder 3 is threadedly connected to the end cover 5, and a through groove 13 is opened in the middle position of the end cover 5. A push pin 14 is fixed in the through groove 13, and the push pin 14 is used to conduct the sealing component in the connecting sleeve 6.

[0026] The screw threaded hole 10 is fixed on the bottom of the aluminum profile 1, and the screw threaded hole 10 is fixed on the aluminum profile 1. The lower ends of the outer walls of the mounting tube 3 on both sides are fixed with a clamping block 9. The inner walls on both sides of the mounting opening are provided with a notch 11. The clamping block 9 is adapted to the notch 11, and the threaded hole 10 is staggered with the mounting hole 8. When the mounting tube 3 is inserted, the two clamping blocks 9 are aligned with the two notches 11 and rotated after insertion so that the clamping block 9 is staggered with the notch 11 after insertion to achieve pre-fixation. A one-way valve 17 is installed on the bottom wall of the mounting tube 3 near the position of the air suction nozzle. We can use an air suction pump to perform a secondary vacuum operation at the air suction nozzle. The one-way valve can ensure one-way transmission of gas and enhance sealing. A connecting frame is fixed in the through groove 13, and one end of the top pin 14 is fixed to the upper part of the connecting frame.

[0027] Furthermore, a sealing groove 12 is provided on the upper part of the end cover 5, and the sealing groove 12 is coaxially provided with the through groove 13. After the mounting cylinder 3 is installed in place, the lower end of the connecting sleeve 6 is inserted into the sealing groove 12. The sealing assembly includes a sealing ring 20 fixedly connected along the inner wall of the connecting sleeve 6. A sealing plug 21 is movably provided in the connecting sleeve 6, and the sealing plug 21 is adapted to the inner wall of the sealing ring 20. A fixing frame 19 is fixed to the upper end of the connecting sleeve 6, and two spring rods 22 are fixed on one side of the fixing frame 19, and the other ends of the spring rods 22 are fixed to one side of the sealing plug 21. After the ejector pin 14 is inserted into the connecting sleeve 6, the sealing plug 21 can be pushed open for conduction.

[0028] The working principle of the present invention is as follows: after the mounting cylinder 3 is installed in place, the push pin 14 pushes the sealing plug 21 to communicate with the inside of the vacuum chamber 7. When mist or water droplets appear in the vacuum chamber 7, the dry particles can continuously and effectively adsorb them to maintain internal dryness. When replacing the dry particles, the screws at both ends of the end plate 4 can be removed and the mounting cylinder 3 can be pulled out, so that the push pin 14 is separated from the sealing plug 21, so that the sealing plug 21 automatically cooperates with the sealing ring 20 to seal the communicating sleeve 6 under the action of the spring rod 22 to prevent air from entering the vacuum chamber 7. Then, the end cover 5 is opened, the dry particles in the annular space 15 are taken out and new particles are filled in, and the end cover 5 is covered and inserted into the mounting cylinder 3. The two blocking blocks 9 are aligned with the two notches 11 and inserted and rotated so that the blocking blocks 9 are misaligned with the notches after insertion to achieve pre-fixation. At this time, the push pin 14 pushes the sealing plug 21 open again, and the air in the mounting cylinder 3 enters the vacuum chamber 7. The interior is not completely vacuum, and a vacuum pump can be used to perform a vacuum operation at the suction nozzle.
