Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner installation and maintenance, in particular to a wall hole blocking device for a copper pipe of an air conditioner outdoor unit. Background Art

[0002] After the outdoor unit of the air conditioner is installed, it is necessary to connect the copper pipe between the indoor and outdoor units. The copper pipe needs to pass through the drilled wall hole. To prevent the entry of air, water, and insects, the wall hole port after passing through the copper pipe needs to be sealed. An existing patent (Announcement No.: CN212868783U) discloses a wall hole sealing device for the copper pipe of the outdoor unit of the air conditioner. This utility model utilizes an axial rod to drive the annular plate to slide to the left end, thereby causing the annular plate to squeeze the rubber hose, causing the rubber hose to pile up and expand, blocking the gap between the outer wall and the inner wall of the wall hole, thereby sealing the wall hole. However, in actual applications, since the sealing of the wall hole is achieved by the rubber hose piling up and rubbing against the wall hole, it is difficult for the rubber hose to move when it rubs against the inner wall of the wall hole. Disassembling the device is time-consuming and labor-intensive, which is not conducive to practical application. To this end, we propose a wall hole sealing device for the copper pipe of the outdoor unit of the air conditioner. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a wall hole blocking device for a copper pipe of an outdoor unit of an air conditioner.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A wall hole sealing device for the copper tube of an air conditioner outdoor unit is designed, comprising an inner tube sleeved on the copper tube, a mounting plate being provided at one end of the inner tube, an outer tube being provided outside the inner tube, a positioning plate being fixed to one end of the outer tube close to the mounting plate and pressed against the wall, a plurality of annular air bags being sleeved on the outer tube, the annular air bags being interconnected, and an inflation pipe and an exhaust pipe being connected to the annular air bags respectively.

[0006] In the above solution, one end of the inner tube is provided with an assembly groove which is threadedly connected to the mounting plate.

[0007] In the above solution, the inner wall of the mounting plate is connected to a filling block located between the copper tube and the inner tube.

[0008] In the above solution, the positioning plate is evenly provided with protrusions on the side close to the wall, the outer tube is threadedly connected to the inner tube, and a handle is fixed on the side of the positioning plate away from the wall.

[0009] In the above solution, the fixed sleeve on the outer tube is provided with a pair of annular plates, the annular airbag is located between the annular plates, a connecting sleeve is provided on the inner side of the annular airbag, screws are connected between the annular plates, and the screws pass through the connecting sleeves in sequence.

[0010] In the above solution, the annular airbags are provided with rubber joints, a delivery pipe is inserted into the rubber joints, and a valve is installed on the exhaust pipe.

[0011] In the above solution, an assembly plate is fixed to the end of the inner tube away from the mounting plate, and a limiting block is provided between the assembly plate and the end of the outer tube away from the positioning plate.

[0012] The advantages and beneficial effects of the present invention are as follows: by arranging an inner tube, an outer tube, a positioning plate, an annular airbag, an inflation tube and an exhaust tube, the inner tube is sheathed on the outside of the copper tube to protect the copper tube, and the positioning plate is used to make the end of the outer tube abut against the wall surface, thereby stably connecting the outer tube to the wall hole, and then combining with the inflation tube to inflate the annular airbag sheathed on the outer tube to expand it, so that the annular airbag is tightly abutted against the inner wall of the wall hole. Compared with the prior art, by inflating the annular airbag, the friction between the outer tube and the inner wall of the wall hole is increased, thereby making the outer tube and the inner wall of the wall hole tightly connected, which can not only avoid the outer tube and the wall hole from being damaged, but also prevent the outer tube from being damaged. The outer tube can be detached from the wall by sliding between them, and the filling gas in the annular airbag can be released through the exhaust pipe, thereby quickly releasing the connection between the outer tube and the inner wall of the wall hole, saving time and effort, and being easy to disassemble and use. By arranging an assembly groove, an installation plate and a filling block, and by connecting the installation plate with the assembly groove, the installation plate and the inner tube are combined, which is convenient for moving the inner tube and cooperating with the filling block to fill the gap between the copper tube and the inner tube, thereby preventing a large amount of dust from entering the gap between the inner tube and the copper tube, thereby achieving a dust-proof effect. Compared with the existing technology, the size of the filling block can be changed to adapt to copper tubes of different radii, and the use is more flexible. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] See also Figure 1-3 The utility model provides a technical solution: a wall hole sealing device for a copper tube of an air conditioner outdoor unit, comprising an inner tube 1 sleeved on the copper tube, and a mounting plate 2 is provided at one end of the inner tube 1;

[0020] Furthermore, one end of the inner tube 1 is provided with a mounting groove 19 that is threadedly connected to the mounting plate 2; by screwing the mounting plate 2 into the inner tube 1, the mounting plate 2 is assembled with the inner tube 1 for easy disassembly;

[0021] Furthermore, the inner wall of the mounting plate 2 is connected to a filling block 3 located between the copper tube and the inner tube 1. The filling block 3 can be set as fireproof EVA, which has a certain elasticity and can fill the gap between the inner tube 1 and the copper tube, and can also achieve a fireproof effect. In addition, most importantly, the use of the filling block 3 can effectively prevent the copper tube from moving inside the inner tube 1, thereby improving the stability of the copper tube.

[0022] Specifically, by setting the assembly groove 19, the mounting plate 2 and the filling block 3, and by connecting the mounting plate 2 to the assembly groove 19, the mounting plate 2 is combined with the inner tube 1, which facilitates the movement of the inner tube 1, and cooperates with the filling block 3 to fill the gap between the copper tube and the inner tube 1, thereby preventing a large amount of dust from entering the gap between the inner tube 1 and the copper tube, thereby achieving a dust-proof effect. Compared with the existing technology, the size of the filling block 3 can be changed to adapt to copper tubes of different radii, which is more flexible in use.

[0023] An outer tube 4 is provided outside the inner tube 1;

[0024] Furthermore, the positioning plate 5 is evenly provided with protrusions 18 on the side close to the wall. The protrusions 18 are rubber and are fixed to the positioning plate 5 in a hemispherical shape. They increase the friction between the positioning plate 5 and the wall and inhibit the movement of the outer tube 4. The outer tube 4 is threadedly connected to the inner tube 1 to facilitate assembly of the two. A handle 6 is fixed on the side of the positioning plate 5 away from the wall. The handle 6 is L-shaped. By controlling the handle 6, it is easy to rotate or pull the positioning plate 5.

[0025] A positioning plate 5 is fixed to one end of the outer tube 4 near the mounting plate 2, and is pressed against the wall. A plurality of annular airbags 8 are sleeved on the outer tube 4. The annular airbags 8 are interconnected, and an inflation tube 13 and an exhaust tube 14 are connected to the annular airbags 8 respectively. The other end of the inflation tube 13 is connected to the output end of the inflation device to supply air, and the exhaust tube 14 is used to discharge the filling gas in the annular airbags 8.

[0026] Furthermore, each of the annular airbags 8 is provided with a rubber joint 11, into which a delivery tube 12 is inserted, which facilitates removal of the delivery tube 12. The delivery tube 12 is used to inflate and deflate the annular airbags 8 one by one. A valve 15 is installed on the exhaust pipe 14, and the exhaust pipe 14 is switched between an open and a closed state by controlling the opening and closing of the valve 15.

[0027] Furthermore, a pair of annular plates 7 are fixedly mounted on the outer tube 4. Figure 2 As shown, the annular plate 7 away from one end of the positioning plate 5 is fixed to the end of the outer tube 4, the annular airbag 8 is located between the annular plates 7, and a connecting sleeve 9 is fixedly provided on the inner side of the annular airbag 8. A screw 10 is connected between the annular plates 7. The screw 10 passes through the connecting sleeve 9 in sequence. A threaded groove that cooperates with the end of the screw 10 is provided on the right annular plate 7. By screwing in the screw 10, the screw 10 is combined with the outer tube 4, thereby limiting the annular airbag 8.

[0028] Furthermore, an assembly plate 17 is fixed to the end of the inner tube 1 away from the mounting plate 2, and a limit block 16 is provided between the assembly plate 17 and the end of the outer tube 4 away from the positioning plate 5; the limit block 16 is used to abut against the end of the outer tube 4, thereby positioning the outer tube 4 and facilitating quick installation;

[0029] Specifically, by arranging an inner tube 1, an outer tube 4, a positioning plate 5, an annular airbag 8, an inflation tube 13 and an exhaust tube 14, the inner tube 1 is used to be sleeved on the outside of the copper tube to protect the copper tube, and the positioning plate 5 is used to make the end of the outer tube 4 abut against the wall surface, thereby stably connecting the outer tube 4 to the wall hole, and then combined with the inflation tube 13, the annular airbag 8 sleeved on the outer tube 4 is inflated to make it expand, so that the annular airbag 8 is tightly pressed against the inner wall of the wall hole. Compared with the existing technology, by inflating the annular airbag 8, the friction between the outer tube 4 and the inner wall of the wall hole is increased, thereby making the outer tube 4 tightly connected to the inner wall of the wall hole, which not only avoids sliding between the outer tube 4 and the wall hole, but also releases the filling gas in the annular airbag 8 through the exhaust tube 14, thereby quickly releasing the connection between the outer tube 4 and the inner wall of the wall hole, saving time and effort, and being easy to disassemble and use.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
