Specific implementation mode
[0022] The following further details the present utility model:
[0023] As Figures 1 to 5 shown, the present utility model provides an adapter seat for a refrigeration air conditioner, including a base body 1 and a connecting pipe 2. A first stepped groove 3 and a second stepped groove 4 are arranged inside the base body 1. The second stepped groove 4 is arranged outside the first stepped groove 3. A first sealing ring 5 is movably clamped inside the first stepped groove 3, and a second sealing ring 6 is movably clamped inside the second stepped groove 4. A threaded connection end is arranged outside the connecting pipe 2, and the connecting pipe 2 is threadedly connected to the inside of the first stepped groove 3. A locking head 7 sleeved outside the connecting pipe 2 is movably installed on the outside of the base body 1.
[0024] By arranging a first stepped groove 3 and a second stepped groove 4 located outside the first stepped groove 3 inside the base body 1, and by setting the size of the second stepped groove 4 to be larger than that of the first stepped groove 3, by connecting the connecting pipe 2 to the inside of the first stepped groove 3 using the threaded connection end, by the inner side of the connecting pipe 2 abutting and squeezing the first sealing ring 5 located in the first stepped groove 3 for sealing, and at the same time by connecting the locking head 7 to the inside of the second stepped groove 4 to squeeze the second sealing ring 6 located in the second stepped groove 4, so that the second sealing ring 6 is squeezed and abutted tightly against the outer wall of the connecting pipe 2 for sealing, thereby improving the sealing effect.
[0025] As Figure 4 shown, the locking head 7 includes a rotating sleeve 71. A first threaded sleeve 72 is fixedly connected to the inside of the rotating sleeve 71. An abutting ring 73 is fixedly connected to the inside of the first threaded sleeve 72. The first threaded sleeve 72 is threadedly connected to the inside of the base body 1.
[0026] As Figure 3 shown, threaded grooves corresponding to the connecting pipe 2 and the first threaded sleeve 72 are respectively arranged on the inner walls of the first stepped groove 3 and the second stepped groove 4.
[0027] By rotating the rotating sleeve 71 along the outside of the base body 1 to drive the first threaded sleeve 72 to be screwed into the base body 1 along the threaded groove on the inner wall of the second stepped groove 4, so that the abutting ring 73 inside the first threaded sleeve 72 abuts the second sealing ring 6 located inside the second stepped groove 4. By the abutting ring 73 squeezing the second sealing ring 6 inward, the second sealing ring 6 abuts against the outer wall of the connecting pipe 2 for secondary sealing, and cooperating with the sealing of the first sealing ring 5 to improve the sealing effect.
[0028] As Figure 4As shown, a clamping groove 74 is formed inside the rotating sleeve 71. A resilient piece 75 is movably clamped inside the clamping groove 74. A second threaded sleeve 76 is threadedly connected to the outside of the clamping groove 74. A handle 77 located outside the rotating sleeve 71 is fixedly connected to the outside of the second threaded sleeve 76.
[0029] Rotate the handle 77 outside the rotating sleeve 71 to thread the second threaded sleeve 76 into the inner side of the clamping groove 74. Since there are two resilient pieces 75 clamped inside the clamping groove 74, the resilient pieces 75 in a "V" shape are extruded and deformed towards the inside by abutting and squeezing against the inner side of the clamping groove 74, so as to be clamped against the outer wall of the connecting pipe 2 for clamping and limiting the connecting pipe 2, improving the connection stability of the connecting pipe 2.
[0030] As Figure 5 shown, the inner side of the abutting ring 73 is provided with an inclined surface that contracts towards the outside.
[0031] Due to the inclined surface that contracts towards the outside on the inner side of the abutting ring 73, when the first threaded sleeve 72 enters the seat body 1, the second sealing ring 6 is extruded to deform towards the inside and abuts against the outer wall of the connecting pipe 2, improving the sealing effect.
[0032] As Figure 3 and Figure 4 shown, there are two resilient pieces 75, and the cross-sections of the two resilient pieces 75 are both in a "V" shape.
[0033] Due to the cross-sections of the two resilient pieces 75 being in a "V" shape, after the resilient pieces 75 are extruded by the clamping groove 74, they deform towards the inside and are clamped on the outer wall of the connecting pipe 2, making the connection more stable.
[0034] As Figure 1 shown, the size of the rotating sleeve 71 is larger than that of the seat body 1.
[0035] Due to the size of the rotating sleeve 71 being larger than that of the seat body 1, it is convenient to twist the rotating sleeve 71.
[0036] As Figure 3 shown, the first sealing ring 5 abuts against the inner side of the connecting pipe 2, and the second sealing ring 6 abuts against the outer wall of the connecting pipe 2.
[0037] By the first sealing ring 5 abutting against the inner side of the connecting pipe 2 and the second sealing ring 6 abutting against the outer wall of the connecting pipe 2, and with the first sealing ring 5 and the second sealing ring 6 located between the seat body 1 and the connecting pipe 2, the sealing effect is improved.
[0038] Next, the working principle of the adapter seat for the refrigeration air conditioner will be specifically described.
[0039] As Figures 1 to 5As shown, one end of the connecting pipe 2 with a threaded connection end is inserted into the interior of the seat body 1 and screwed in to be connected with the threaded groove on the inner wall of the first stepped groove 3. When the connecting pipe 2 is screwed to the innermost end, its inner side presses the first sealing ring 5 located inside the first stepped groove 3 to seal its interface. Subsequently, by rotating the rotating sleeve 71 along the outside of the seat body 1, the first threaded sleeve 72 is screwed into the seat body 1 along the threaded groove on the inner wall of the second stepped groove 4, so that the abutting ring 73 inside the first threaded sleeve 72 abuts against the second sealing ring 6 located inside the second stepped groove 4. Due to the inclined surface of the inner side of the abutting ring 73 being set to contract outward, the abutting ring 73 presses the second sealing ring 6 inward, so that the second sealing ring 6 abuts against the outer wall of the connecting pipe 2 for secondary sealing, improving the sealing effect. After connecting the connecting pipe 2 with the seat body 1, the turning handle 77 on the outside of the rotating sleeve 71 is rotated, so that the turning handle 77 drives the second threaded sleeve 76 to be screwed into the inside of the clamping groove 74. Since two elastic pieces 75 are clamped inside the clamping groove 74, when the inside of the clamping groove 74 abuts against and presses the elastic pieces 75, the elastic pieces 75 arranged in a "V" shape are deformed by extrusion and press inward to be clamped against the outer wall of the connecting pipe 2 to clamp and limit the connecting pipe 2.
[0040] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
