It should be understood that the numerals used in this way are interchangeable where appropriate so that the embodiments of the invention described herein can be implemented in an order other than those illustrated or described herein.

[0067] The embodiment of this specification provides a combined barrel body, including a first barrel body component, a second barrel body component and a sealing strip 3;

[0068] The first barrel body assembly includes a first connecting portion, which is arranged at the opening end of the first barrel body assembly, and a docking protrusion 11 is arranged on the first connecting portion;

[0069] The second barrel body assembly includes a second connecting portion, which is arranged at the open end of the second barrel body assembly, and the second connecting portion is provided with a docking groove 21 for mating with the first connecting portion, and the notch width of the docking groove 21 is greater than the groove bottom width;

[0070] A sealing strip 3 is arranged between the docking protrusion 11 and the docking groove 21. The sealing strip 3 is provided with a sealing groove 31 for cooperating with the docking protrusion 11. The outer surface of the sealing strip 3 is provided with at least one sealing protrusion 32 continuously arranged along the circumference of the sealing strip 3. The sealing protrusion 32 is interference fit with the docking groove 21.

[0071] When the docking protrusion 11 is engaged with the docking groove 21, the docking protrusion 11 can press the sealing strip 3 into the docking groove 21 under the action of the first barrel body component's own gravity and / or external force to achieve sealing.

[0072] It should be noted that the first barrel body component and the second barrel body component in the embodiment of this specification are used to distinguish different barrel body components that cooperate with each other to achieve a sealed connection. For the convenience of description, in the embodiment of this specification, the barrel body component with the first connecting part in the two barrel body components that cooperate with each other is called the first barrel body component, and the barrel body component with the second connecting part is called the second barrel body component. In addition, other naming methods that can clearly and accurately distinguish different barrel body components in description can also be used in this article, and this embodiment is not limited to this.

[0073] The relationship between the first barrel body component and the second barrel body component is described below by taking a certain intermediate barrel body component as an example: a certain intermediate barrel body component has two oppositely arranged open ends, wherein one open end is provided with a first connecting portion and the other open end is provided with a second connecting portion. When the intermediate barrel body component cooperates with the second connecting portion provided on another barrel body component through the first connecting portion provided on it, the intermediate barrel body component exists as the first barrel body component described above. When the intermediate barrel body component cooperates with the first connecting portion provided on another barrel body component through the second connecting portion provided on it, the barrel body component exists as the second barrel body component described above.

[0074] Similarly, when a barrel body component only has a first connection portion, the barrel body component can only exist as a first barrel body component; illustratively, a barrel body component is installed on the top of the barrel body, one end of which is provided with a first connection portion, and the other end is provided with a barrel cover, then the barrel body component can only exist as a first barrel body component. Exemplarily, a barrel body component is installed on the bottom of the barrel body, one end of which is provided with a first connection portion, and the other end is provided with a barrel bottom, then the barrel body component can only exist as a first barrel body component. Exemplarily, a barrel body component is installed in the middle of the barrel body, one end of which is provided with a first connection portion, and the other end is provided with a first connection portion, then the barrel body component can only exist as a first barrel body component.

[0075] Correspondingly, when a barrel body assembly only has a second connecting portion, the barrel body assembly can only exist as a second barrel body assembly. Exemplarily, a barrel body assembly is installed at the top of the barrel body, one end of which is provided with a second connecting portion, and the other end is provided with a barrel cover, then the barrel body assembly can only exist as a first barrel body assembly. Exemplarily, a barrel body assembly is installed at the bottom of the barrel body, one end of which is provided with a second connecting portion, and the other end is provided with a barrel bottom, then the barrel body assembly can only exist as a first barrel body assembly. Exemplarily, a barrel body assembly is installed in the middle of the barrel body, one end of which is provided with a second connecting portion, and the other end is provided with a second connecting portion, then the barrel body assembly can only exist as a first barrel body assembly.

[0076] The combined barrel provided in the embodiment of this specification adopts a stacking structure, which divides the barrel into several barrel body components for assembly and installation. Compared with the barrel body with an integrated structure, it is not limited by production equipment, has good economy and practicality, and minimizes the packaging size and reduces the packaging and transportation costs. Preferably, the several barrel body components constituting the same combined barrel can be overlapped and nested when separated, which is convenient for saving transportation space and easy to carry.

[0077] Figure 1 is a schematic structural diagram of a combined barrel provided by an embodiment of the present invention, Figure 2 yes Figure 1 Exploded diagram of Figure 3 yes Figure 1 The cross-sectional view along the SS section is shown in Figure 1 , Figure 2 and Figure 3 As shown, in a specific embodiment, the combined barrel body assembly includes four barrel body assemblies, which are divided according to the installation position of each barrel body assembly on the barrel body, from top to bottom, they are an upper cover 81, a middle upper cover 82, a middle lower cover 83 and a lower cover 84.

[0078] One end of the upper cover 81 has a barrel end surface used as a barrel cover, and the other end is an open end provided with a second connecting portion, and the second connecting portion is provided with a docking groove 21; that is, the upper cover 81 can only be used as the second barrel assembly described above;

[0079] Both ends of the middle upper cover 82 are open ends. One end of the middle upper cover 82 is provided with a first connection portion, on which a docking protrusion 11 is provided. The other end of the middle upper cover 82 is provided with another first connection portion, on which another docking protrusion 11 is provided. In other words, the middle upper cover 82 can only be used as the first barrel assembly described above.

[0080] Both ends of the middle lower cover 83 are open ends, one end of the middle lower cover 83 is provided with a first connecting portion, the first connecting portion is provided with a docking protrusion 11, and the other end is provided with a second connecting portion, the second connecting portion is provided with a docking groove 21; that is, the middle lower cover 83 is used as a second barrel body component when it is matched with the middle upper cover 82, and is used as a first barrel body component when it is matched with the lower cover 84.

[0081] One end of the lower cover 84 has a barrel end surface serving as the barrel bottom, and the other end is an open end having a second connecting portion having a docking groove 21 ; that is, the lower cover 84 can only be used as the second barrel assembly described above.

[0082] The connection relationship of the above-mentioned four barrel body components includes: the docking groove 21 of the upper cover 81 is connected to a docking protrusion 11 of the middle upper cover 82, another docking protrusion 11 of the middle upper cover 82 is connected to the docking groove 21 of the middle lower cover 83, and the docking protrusion 11 of the middle lower cover 83 is connected to the docking groove 21 of the lower cover 84.

[0083] In one possible embodiment, the combined barrel body assembly includes two first barrel body assemblies and one second barrel body assembly (not shown), wherein one first barrel body assembly has a barrel body end surface serving as a barrel cover and an open end provided with a first connecting portion, the other first barrel body assembly has a barrel body end surface serving as a barrel bottom and an open end provided with a first connecting portion, and the second barrel body assembly has two opposite open ends provided with second connecting portions.

[0084] The connection relationship between the above-mentioned two first barrel body components and one second barrel body component is as follows: the first connection part of a first barrel body component is connected to a second connection part of the second barrel body component, and the first connection part of another first barrel body component is connected to another second connection part of the second barrel body component.

[0085] It should be noted that the first barrel body assembly and the second barrel body assembly in the embodiments of this specification are used to distinguish different barrel body assemblies that cooperate with each other to achieve a sealed connection in the description.

[0086] Figure 4 is a cross-sectional view of the barrel assembly connection structure provided by an embodiment of the present invention, such as Figure 4 As shown, in a specific example, the middle upper cover 82 is cooperatively connected with the middle lower cover 83. At this time, the middle upper cover 82 is the first barrel body component, and the middle lower cover 83 is the second barrel body component. The first connecting part of the middle upper cover 82 is provided with a docking protrusion 11, and the second connecting part of the middle lower cover 83 is provided with a docking groove 21. A sealing strip 3 is provided between the docking protrusion 11 and the docking groove 21.

[0087] In one embodiment, the width of the opening of the docking groove 21 is greater than the width of the groove bottom. A structure with a large opening and a small bottom is adopted to facilitate pressing the sealing strip 3 into the docking groove 21 .

[0088] In some possible embodiments, the width of at least a portion of the docking groove 21 in the direction from the groove opening to the groove bottom gradually decreases from the groove opening to the groove bottom. For example, the side surface of the docking groove 21 may have a step-like structure, and the side surface of at least one step in the step-like structure is inclined to the groove bottom surface.

[0089] In some improved embodiments, the width of the butt joint groove 21 gradually decreases from the groove opening to the groove bottom. The groove structure provided in this embodiment has a guiding effect on the sealing strip 3 entering the butt joint groove 21, which is helpful to prevent the sealing strip 3 from deflecting during being pressed into the butt joint groove 21.

[0090] There are many implementations for gradually decreasing the width of the butt joint groove 21 from the groove opening to the groove bottom, the outer contour shape of the sealing strip 3 is adapted to the shape of the butt joint groove 21, and the shape of the sealing groove 31 of the sealing strip 3 is adapted to the shape of the butt joint protrusion 11. That is, when the shape of the butt joint protrusion 11 is determined, the thickness of each part of the sealing strip 3 is adapted to the width of the corresponding part of the butt joint groove 21.

[0091] Specifically, the groove side of the docking groove 21 can be a combination of any one or more of a straight line surface, a broken line surface and a curved surface, wherein the straight line surface is a curved surface formed by the straight line extending along the length direction or circumferential movement of the docking groove 21, the broken line surface is a curved surface formed by the broken line extending along the length direction or circumferential movement of the docking groove 21, and the curved surface is a curved surface formed by the curve extending along the length direction or circumferential movement of the docking groove 21.

[0092] Specifically, the angle between the groove side and the normal to the groove bottom is 0° to 90°, preferably 1° to 30°, especially 1° to 20°, and illustratively, can be 2°, 6°, 15° or 45°.

[0093] In some possible embodiments, when the angle between the normal of the groove side and the groove bottom is 0°, the docking groove 21 provided in this embodiment can cooperate with the sealing strip 3 to play a sealing role, but the groove side and the groove bottom are perpendicular to each other, so that the groove side has no guiding effect on the sealing strip 3, which is not conducive to installing the sealing strip 3 into the docking groove 21.

[0094] In some possible embodiments, a docking plane for mating with the first connecting part is provided on the second connecting part (the angle between the normal of the corresponding groove side and the groove bottom is 90°, in which case the groove side and the groove bottom are on the same plane, and the groove side and the groove bottom cannot form a groove structure), and the docking plane cooperates with the sealing strip 3 for sealing.

[0095] Compared with the aforementioned embodiment in which the docking groove 21 is provided on the second connection part, since the docking plane used in this embodiment does not have a limiting function, when the external force is greater than the friction between the docking plane and the sealing strip 3, the docking plane and the sealing strip 3 are easily displaced, which may affect the sealing performance. Therefore, the sealing performance can be ensured by adding a limiting structure of the sealing strip 3, and the sealing performance can also be ensured by using it in conjunction with the connector 4.

[0096] Connecting the first barrel body assembly and the second barrel body assembly by the connecting member 4 can prevent the docking protrusion 11 from shifting from the docking plane, thereby preventing the sealing strip 3 sleeved on the docking protrusion 11 from shifting from the docking plane. At the same time, connecting the first barrel body assembly and the second barrel body assembly by the connecting member 4 can press the docking protrusion 11 and the docking plane 21 tightly, thereby increasing the extrusion force between the sealing protrusion 32 and the docking plane 21. The tighter the pressure, the better the sealing effect.

[0097] In one embodiment, the first connection part is provided with a first docking plane instead of the docking protrusion 11, the second connection part is provided with a second docking plane instead of the docking groove 21, the sealing strip 3 has a first side surface and a second side surface which are arranged opposite to each other, the first side surface and the second side surface are both perpendicular to the axial direction of the barrel body assembly, the first side surface is provided with a plurality of sealing strips 3 for sealingly cooperating with the first docking surface, and the second side surface is provided with a plurality of sealing strips 3 for sealingly cooperating with the second docking surface. Connecting the first barrel body assembly and the second barrel body assembly through the connecting member 4 can press the first docking plane, the sealing strip 3 and the second docking plane tightly to avoid displacement between the three, and the tighter the pressing, the better the sealing effect.

[0098] Figure 5 A cross-sectional view of a sealing strip provided by an embodiment of the present invention is shown in FIG. Figure 5 As shown, the sealing strip 3 is provided with a sealing groove 31 for cooperating with the docking protrusion 11, and the outer surface of the sealing strip 3 is provided with at least one sealing protrusion 32 which is continuously arranged along the circumference of the sealing strip 3. The sealing protrusion 32 is annular in shape, and at least one sealing protrusion 32 is coaxially arranged, and the sealing protrusion 32 and the sealing strip 3 are coaxially arranged.

[0099] It should be noted that Figure 4 and Figure 5 The figure shows a cross-sectional view of the same section of the same sealing strip. Figure 4 The sealing strip shown uses a different Figure 5 The filling method is to make the outer contour of the sealing strip 3 clear, rather than to indicate that the two materials are different.

[0100] like Figure 4As shown, the butt protrusion 11 can extend into the sealing groove 31 of the sealing strip 3, and the end of the butt protrusion 11 abuts against the bottom of the sealing groove 31. During the installation process, the butt protrusion 11 can apply pressure to the sealing strip 3 under the weight of the barrel assembly and external force, so that the sealing strip 3 moves toward the butt groove 21 under the action of the butt protrusion 11 until the sealing strip 3 is completely pressed into the butt groove 21.

[0101] Specifically, the sealing protrusion 32 is interference fit with the docking groove 21 to obtain a good sealing pressure. The sealing protrusion 32 is made of an elastic material with good extrusion deformation performance. For example, the elastic material is EPDM rubber or silicone. The sealing protrusion 32 can be squeezed and pressed against the docking groove 21 under appropriate pressure, forming an interference fit with the docking groove 21, solving the problem that the existing docking groove 21 has a large deviation and cannot ensure the sealing effect, allowing the docking groove 21 to have deviations within a certain range, reducing the requirements for processing accuracy. In addition, the provision of the sealing protrusion 32 is also conducive to avoiding displacement between the sealing strip 3 and the docking groove 21.

[0102] Specifically, a connecting section is further provided on the outer surface of the sealing strip 3, and two adjacent sealing protrusions 32 are connected by the connecting section. The connecting section is clearance-matched with the docking groove 21, which guides the deformation of the sealing protrusion 32 and facilitates the extrusion deformation of the sealing protrusion 32. The multiple sealing protrusions 32 and the multiple connecting sections on the protrusion setting surface are alternately arranged to form an undulating groove shape.

[0103] In one embodiment, Figure 5 As shown, the cross-sectional shape of the sealing protrusion 32 may be semicircular, and the connecting section may be an arc surface and / or a plane constituting the protrusion setting surface. The connecting section is provided between adjacent sealing protrusions 32 to facilitate the extrusion deformation of the sealing protrusions 32 .

[0104] In some possible embodiments, the connecting section can also be a connecting protrusion protruding from the outer surface of the sealing strip 3, the distal surface of the connecting protrusion is away from the protrusion setting surface of the sealing strip 3, the distal surface of the sealing protrusion 32 is away from the protrusion setting surface of the sealing strip 3, and the distance between the distal surface of the sealing protrusion 32 and the protrusion setting surface is greater than the distance between the distal surface of the connecting protrusion and the protrusion setting surface, so as to facilitate pressing the sealing strip 3 into the docking groove 21.

[0105] In some possible embodiments, the cross-sectional shape of the connecting section may also be bullet-shaped, circular, elliptical, polygonal, etc.; the cross-sectional shape of the sealing protrusion 32 may also be bullet-shaped, elliptical, and polygonal, to ensure that the sealing protrusion 32 forms a sealing contact surface with the docking groove 21, wherein the polygon includes but is not limited to a triangle, rectangle, trapezoid, etc.

[0106] The width e of the connecting section is the distance between adjacent sealing protrusions 32. The width e of the connecting section is 0 to 10 times, preferably 0.3 to 5 times, especially 0.5 to 3 times, and illustratively, can be 0.7 times, 1 times or 4 times the width f of the sealing protrusion 32.

[0107] In a possible embodiment, a sealing protrusion 32 may be provided on the outer surface of the sealing strip 3. The sealing protrusion 32 fits tightly with the docking groove 21 to form a barrier to prevent the liquid in the barrel from leaking out, thereby achieving better sealing and impermeability. There is no need to set up a water storage bag, the overall weight is light, and assembly is convenient.

[0108] In an improved embodiment, a plurality of sealing protrusions 32 may be further provided on the outer surface of the sealing strip 3. The interference fit between the plurality of sealing protrusions 32 and the docking groove 21 can form multiple sealing guarantees. When one or more sealing protrusions in the multiple sealing guarantees fail, the remaining effective sealing protrusions can still prevent the liquid in the barrel from leaking out. Compared with the above-mentioned solution of providing a sealing protrusion 32 on the outer surface of the sealing strip 3, the increase in the number of sealing protrusions 32 improves the reliability of the sealing performance.

[0109] In one embodiment, the outer surface of the sealing strip 3 includes a groove setting surface and a convex setting surface, the groove setting surface is provided with a sealing groove 31, and the sealing groove 31 is continuously provided along the circumference of the sealing strip 3, and the convex setting surface is provided with a sealing convexity 32, and the sealing convexity 32 is continuously provided along the circumference of the sealing strip 3.

Exemplarily, the width of the groove opening end of the sealing groove 31 is 1.8 mm, and the width a of the groove bottom is 1.8 mm. The sealing groove 31 structure provided in this embodiment can be installed in the following order, specifically: first install the sealing strip 3 on the docking protrusion 11, and then insert the docking protrusion 11 installed with the sealing strip 3 into the docking groove 21.

[0112] Figure 6 is a cross-sectional view of a sealing strip provided by an embodiment of the present invention, such as Figure 6As shown, in some improved embodiments, the width of the bottom of the groove is a, and the angle between the two sides of the sealing groove 31 is α.

Exemplarily, the angle α between the two sides of the sealing groove 31 is 8°, the width of the groove opening end of the sealing groove 31 is 2.1mm, and the width a of the bottom of the groove is 1.8mm.

The width of the opening end of the groove is smaller than the width a of the bottom of the groove, and the cross-section of the sealing groove 31 forms a gradual structure with a small mouth and a large bottom, which is approximately in the shape of a dovetail groove. Exemplarily, the angle between the groove side of the sealing groove 31 and the normal to the bottom of the groove is -2°, the width of the opening end of the sealing groove 31 is 2.1mm, and the width a of the bottom of the groove is 2.3mm. The sealing groove 31 structure provided in this embodiment is conducive to preventing the sealing groove 31 from falling off the docking protrusion 11, and compared with the implementation method in which the groove width is consistent from top to bottom, it improves the controllability of installation and reduces the difficulty of operation.

[0114] It should be noted that Figure 6 and Figure 7 The cross section of the sealing strip shown is similar to Figure 5 The cross-sectional structure and material of the sealing strip shown are consistent.

Specifically, the height c of the sealing strip 3 is 2 to 20 mm, preferably 3 to 15 mm, especially 5 to 12 mm, and illustratively, it can be 6 mm or 18 mm. It should be noted that the annular structure here is a closed structure, including but not limited to a circular ring, an elliptical ring, a square ring and a special-shaped ring, and the present embodiment is not limited thereto.

[0122] During the process of pressing the sealing strip 3 into the docking groove 21, when the distance between the second surface and the bottom surface of the docking groove 21 is less than or equal to the first preset distance, the first surface and the third surface respectively form a sealing connection with the side surfaces of the docking groove 21; when the interference between the second surface and the bottom surface of the docking groove 21 is greater than or equal to the second preset distance, the second surface also forms a sealing connection with the bottom surface of the docking groove 21. At this point, the first surface, the second surface and the third surface all form a sealing connection with the docking groove 21.

[0133] Figure 8 Flow chart of the method for installing the combined barrel provided by the embodiment of the present invention. Figure 8 As shown, the embodiment of this specification also provides a method for installing a combined barrel body. Figure 1 In the case of a combined barrel body including an upper cover 81, a middle upper cover 82, a middle lower cover 83 and a lower cover 84, the method may include the following steps:

[0134] S1: clamp the sealing strip 3 on a docking protrusion 11 of the middle upper cover 82, and then clamp the middle upper cover 82 with the sealing strip 3 into the docking groove 21 of the upper cover 81, and use the connecting member 4 (such as a self-tapping screw) to connect the middle upper cover 82 and the upper cover 81 to obtain the upper cover 81 assembly;

[0135] S2: clamp the sealing strip 3 on the docking protrusion 11 of the middle and lower cover 83, and then clamp the middle and lower cover 83 with the sealing strip 3 into the docking groove 21 of the lower cover 84, and connect the middle and lower cover 83 and the lower cover 84 using the connecting member 4 to obtain the lower cover 84 assembly;

[0137] Among them, the structures of the upper cover 81, the middle upper cover 82, the middle lower cover 83 and the lower cover 84 are recorded in the above embodiments and will not be repeated here. The sealing strip 3 in steps S1, S2 and S3 does not refer to the same sealing strip 3.

[0138] Among them, steps S1, S2 and S3 can be executed in the order described in the above embodiment, or can be executed in a manner different from the above order. For example, steps S1, S2 and S3 can be performed simultaneously.

[0139] Figure 8 The flowchart shown is only for Figure 1 The installation method of the combined barrel body shown is for illustration only and should not be regarded as a limitation on the embodiments of this specification. When the structure of the combined barrel body is different, the installation method and installation steps of the combined barrel body can be adjusted accordingly, and the specific implementation method will not be described in detail.

[0140] It should be noted that Figure 8 The installation method shown is applicable to a combined barrel structure in which the docking protrusion 11, the docking groove 21 and the sealing strip 3 are separately arranged.

[0141] In some alternative embodiments, there is also a situation where the sealing strip 3 and the docking protrusion 11 are integrally arranged. For example, the sealing strip 3 and the docking protrusion 11 can be made into an integral structure by multi-material injection molding; wherein the multi-material injection molding includes but is not limited to secondary injection molding. The structure in which the sealing strip 3 and the docking protrusion 11 are integrally arranged can directly plug the first barrel body component and the second barrel body component, omitting the step of installing the sealing strip 3, and can also prevent the sealing strip 3 from falling off the docking protrusion 11 during the installation process, and prevent the sealing strip 3 from running off during the process of being pressed into the docking groove 21, which is conducive to reducing the difficulty of operation and improving the installation efficiency.

[0142] In some alternative embodiments, there is also a situation where the sealing strip 3 and the docking groove 21 are integrally arranged. For example, the sealing strip 3 and the docking groove 21 can be made into an integral structure by multi-material injection molding; wherein the multi-material injection molding includes but is not limited to secondary injection molding. The structure in which the sealing strip 3 and the docking groove 21 are integrally arranged can directly plug the first barrel body component and the second barrel body component, omitting the step of installing the sealing strip 3, and can also prevent the sealing strip 3 from deviating during the process of being pressed into the docking groove 21, which is conducive to reducing the difficulty of operation and improving the installation efficiency.

[0143] In addition, when the sealing strip 3 is integrally provided with the docking groove 21, the shape of the docking groove may no longer be limited to the structure in which the notch width is greater than the groove bottom width as described in the embodiment of this specification. Exemplarily, the notch width of the docking groove is less than the groove bottom width, and the docking groove includes but is not limited to a dovetail groove. Exemplarily, the notch width of the docking groove is equal to the groove bottom width, and the docking groove includes but is not limited to a groove with a rectangular cross section.

[0144] In one embodiment, the barrel body assembly is provided with an installation indicating structure (not shown) for indicating the assembly direction and / or for indicating the assembly position on the modular barrel body. The installation indicating structure can quickly understand the installation sequence and direction between the barrel body assemblies of the same barrel body to avoid installation errors.

[0145] The installation indication structure may also be a digital mark set on the surface of the barrel body component, such as "1", "2", "3", etc. The digital mark is used to indicate the installation sequence between the barrel body components. The installation indication structure may also be implemented in other ways, which are not limited here.

[0146] like Figure 1 As shown, the combined barrel body includes several barrel body components, and the several barrel body components that constitute the same combined barrel body can overlap and nest to reduce the space occupied by transportation. In this way, barrels of various capacities can be combined as needed by rationally combining the barrel body components, which is convenient for standardization and mass production of barrel body components. They can also be nested and shrunk to the maximum extent when not in use, minimizing the occupied space as much as possible, making it easy to place or carry, and can be used in a mobile manner. It can be widely used in military, disaster relief, tap water supply, water heaters, seawater desalination, household rainwater collection and other scenarios.

[0151] In the embodiment of the present specification, based on the weight of the barrel body assembly itself, the docking protrusion 11 and the docking groove 21 are pressed tightly by the connecting piece 4, thereby increasing the extrusion force between the sealing protrusion 32 and the docking groove 21. The tighter the pressure, the better the sealing effect. Compared with the solution of relying solely on the weight of the barrel body assembly itself to squeeze the sealing protrusion 32 and the docking groove 21, it has a better sealing effect.

[0152] Preferably, the connection member 4 includes a self-tapping screw.
