The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, and this embodiment provides an air-conditioning pipe connection sealing mechanism, which includes a first sealing mechanism 100 and a second sealing mechanism 200. The second sealing mechanism 200 can seal the connection between the two pipe flanges, effectively improving the effect that cannot be achieved by a single rubber gasket seal. The first sealing mechanism 100 can perform a secondary seal on the two pipe connection heads, effectively improving the sealing performance of the air-conditioning pipe connection, and at the same time, it is convenient and quick to install.

[0031] Specifically, the first sealing mechanism 100 includes a cover body 101, a sealing gasket 102, a clamping assembly 103 and a limiting assembly 104. The sealing gasket 102 is fixedly connected to the surface of the cover body 101, and the clamping assembly 103 and the limiting assembly 104 are respectively installed on both sides of the surface of the cover body 101.

[0032] The cover body 101 is made of stainless steel, which has strong corrosion resistance and can resist the erosion of air pollutants, acids and alkalis, seawater and sewage, ensuring the long-term use of the sealing mechanism. The sealing gasket 102 is made of corrosion-resistant rubber, and the clamping component 103 is compatible with the limit component 104.

[0033] Specifically, the second sealing mechanism 200 is installed on the inner surface of the cover body 101, and includes a semi-sealing ring 201, a first spring 202 and a pressure-applying component 203.

[0034] The surface of the semi-sealing ring 201 contacts the inner wall of the cover body 101. There are several first springs 202, and they are distributed in a circular array on the inner wall of the semi-sealing ring 201. The pressure-applying component 203 can apply pressure to the semi-sealing ring 201 so that it is in close contact with the outer surface of the pipe flange, thereby achieving a sealing effect.

[0035] Example 2

[0036] Reference Figures 2 to 6 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0037] Specifically, the snap-fit assembly 103 includes a first block 103a, a snap-fit member 103b, a pressing member 103c and a groove 103d. The first block 103a is fixedly connected to the surface of the cover body 101, the groove 103d is opened inside the first block 103a, the snap-fit member 103b is installed in the inner cavity of the groove 103d, and the pressing member 103c is installed on the surface of the first block 103a.

[0038] The pressing member 103c contacts the clamping member 103b. Pressing the pressing member 103c can move the clamping member 103b in the groove 103d.

[0039] The limiting assembly 104 includes a second block 104a and a docking groove 104b. The second block 104a is fixedly connected to the surface of the cover 101, and the docking groove 104b is opened inside the second block 104a.

[0040] The first block 103a and the second block 104a have the same size, and the same type of material can be used during processing and production, thereby reducing procurement costs.

[0041] The limiting assembly 104 also includes a first square column 104c, a push plate 104d and a second spring 104e. The first square column 104c is slidably connected to the inner wall of the docking groove 104b, the push plate 104d is fixedly connected to one end of the first square column 104c, and the two ends of the second spring 104e are respectively fixedly connected to the surface of the first square column 104c and the inner wall of the docking groove 104b.

[0042] The first square column 104c serves as a guide and positioning for the push plate 104d, and the second spring 104e is compressed to generate an elastic force to generate a thrust on the push plate 104d. When the clamping block 103b-2 moves in the docking groove 104b and needs to be disengaged, it can be pushed out of the docking groove 104b under the action of the push plate 104d, thereby facilitating disassembly.

[0043] The clamping member 103b includes a second square column 103b-1, a clamping block 103b-2 and a third spring 103b-3. The second square column 103b-1 is slidingly connected to the inner wall of the groove 103d, the clamping block 103b-2 is fixedly connected to one end of the second square column 103b-1, and the two ends of the third spring 103b-3 are respectively fixedly connected to the surface of the second square column 103b-1 and the inner wall of the groove 103d.

[0044] The second square column 103b-1 serves as a guide and limiter for the clamping block 103b-2. When the clamping block 103b-2 moves and pushes the second square column 103b-1 to move, the third spring 103b-3 is compressed. When the clamping block 103b-2 is inserted into the docking groove 104b, the clamping block 103b-2 moves and is clamped in the docking groove 104b under the action of the rebound of the third spring 103b-3.

[0045] The pressing member 103c includes a push column 103c-1, a pressing block 103c-2 and a guide column 103c-3. One end of the push column 103c-1 passes through the first block 103a and is slidably connected to it. The pressing block 103c-2 is fixedly connected to the other end of the push column 103c-1. The guide column 103c-3 is fixedly connected to the surface of the push column 103c-1.

[0046] By pressing the pressing block 103c-2, the push column 103c-1 can be pushed to move, thereby pushing the clamping block 103b-2 to move. After loosening, the clamping block 103b-2 can push the push column 103c-1 under the action of the rebound of the third spring 103b-3 to reset the pressing block 103c-2.

[0047] A guide groove adapted to the guide post 103c - 3 is formed inside the first block 103a , and the guide post 103c - 3 is slidably connected to the inner wall of the guide groove.

[0048] The guide post 103c-3 and the guide groove are used to guide and limit the push post 103c-1 so that the push post 103c-1 will not separate from the first square post 104c.

[0049] The pressure-applying assembly 203 includes a semi-ring plate 203a, a round rod 203b, a fixed rod 203c, a guide hole 203d and a limiting rod 203e. The semi-ring plate 203a is fixedly connected to the inner surface of the cover body 101. One end of the fixed rod 203c passes through the interior of the semi-sealing ring 201 and is fixedly connected thereto. The other end of the fixed rod 203c is fixedly connected to the surface of the round rod 203b. The guide hole 203d is opened on the surface of the semi-ring plate 203a. Both ends of the round rod 203b extend to the inner cavity of the guide hole 203d. One end of the limiting rod 203e passes through the interior of the semi-sealing ring 201 and is fixedly connected thereto.

[0050] The round rod 203b and the semi-sealing ring 201 are fixedly connected by the fixing rod 203c. After the two cover bodies 101 are merged, the limiting rod 203e is located between the bolts at the flange connection. When the cover body 101 is rotated, the semi-sealing ring 201 rotates with it. When the limiting rod 203e contacts the bolt, the semi-sealing ring 201 cannot rotate anymore, thereby playing a limiting role. As the cover body 101 rotates, the semi-annular plate 203a squeezes the round rod 203b due to the design of the guide hole 203d, causing the round rod 203b to move in the guide hole 203d, squeezing the semi-sealing ring 201, making it closely contact with the outer surface of the flange to perform a sealing function.

[0051] A positioning groove is provided on the surface of the semi-sealing ring 201 , and a positioning block is fixedly connected to the surface of the semi-sealing ring 201 , and the positioning block is adapted to the positioning groove.

[0052] Through the positioning groove and the positioning block, the two half sealing rings 201 are butted together during the butt-jointing and closing process of the two cover bodies 101 , thereby forming a complete sealing ring.

[0053] A docking hole 105 is formed on the surface of the second block 104a, and a docking rod 106 is fixedly connected to the surface of the first block 103a. The docking rod 106 is adapted to the docking hole 105, and one end of the docking rod 106 passes through the docking hole 105 and extends to the outside of the second block 104a.

[0054] During sealing, the docking rod 106 is inserted into the docking hole 105 to pre-position the two cover bodies 101 , thereby facilitating the subsequent connection between the clamping assembly 103 and the limiting assembly 104 .

[0055] When in use, the two covers 101 are covered at the connection of the pipe flange, and the docking rod 106 connected to the first block 103a on one cover 101 is inserted into the docking hole 105 opened in the second block 104a on the other cover 101, so that the two covers 101 are pre-positioned, and the two covers 101 are pressed together, and the clamping block 103b-2 contacts and squeezes the inclined part of the surface of the second block 104a, so that the clamping block 103b-2 and the second column 103b-1 move, and the third spring 103b-3 is compressed. The clamping block 103b-2 moves and is inserted into the docking groove 104b, and presses the push plate 104d to move, thereby moving the first square column 104c and compressing the second spring 104e. When the two sealing gaskets 102 are in close contact and the positioning blocks on the two half sealing rings 201 are inserted into the positioning grooves, the clamping block 103b-2 moves and is clamped in the docking groove 104b under the action of the rebound of the third spring 103b-3. The two half sealing rings 201 form a complete sealing ring that is sleeved on the outer surface of the flange, and the limiting rod 203e is located between the bolts at the flange connection.

[0056] When the cover body 101 is rotated, the half sealing ring 201 rotates with it. When the limiting rod 203e contacts the bolt, the half sealing ring 201 cannot rotate, thereby playing a limiting role. The half ring plate 203a rotates with the cover body 101. Due to the design of the guide hole 203d, the half ring plate 203a squeezes the round rod 203b, causing the round rod 203b to move in the guide hole 203d, squeezing the half sealing ring 201, making it closely contact with the outer surface of the flange to play a sealing role. After rotating to a certain angle, the round rod 203b The arc-shaped card slot in the guide hole 203d is limited, and double sealing is achieved by the action of two sealing gaskets 102 and the cover body 101. When disassembly is required, the pressing block 103c-2 is pressed to move the push column 103c-1 to push the card block 103b-2 to move, and disengage from the limit of the docking groove 104b. Under the action of the rebound of the second spring 104e, the push plate 104d is pushed to move, and then the card block 103b-2 is pushed to move away from the second block 104a, completing the disassembly, thereby achieving quick disassembly and assembly.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
