Description

Technical Field

[0001] This application relates to the field of mechanical leak sealing technology, and in particular to a leak sealing device. Background Technology

[0002] Currently, in fields such as aerospace, the maintenance and safety of certain specialized equipment are of paramount importance. This is especially true for critical processes such as fuel storage and filling. Fuel storage devices are typically spherical, with a fuel filling nozzle at their maximum diameter. Workers fill the sphere with fuel through this nozzle. The fuel is unsymmetrical dimethylhydrazine (UDMH), a highly toxic fuel, so leaks must be prevented to avoid personal injury and environmental impact.

[0003] Currently, in related technologies, the purpose of preventing fuel injection nozzle leakage is achieved by welding a plug onto the fuel injection nozzle.

[0004] However, welding is not suitable for sealing leaks when the fuel storage device is made of non-metallic materials. Furthermore, the spheres are fixed in place by a support structure, and the vertical ribs of this structure are close to the sphere, severely limiting the space for sealing operations. Additionally, the support structure is wrapped with thermal insulation material, requiring measures to prevent damage beyond utilizing existing openings in the support structure itself. Drilling or other operations on the support structure are not permitted, making it susceptible to interference with the sealing structure. Welding also poses a significant risk of damaging the thermal insulation material of the support structure. These factors make the installation of a sealing structure difficult.

[0005] The aforementioned technologies have the drawback that the leak-sealing structure is difficult to install. Utility Model Content

[0006] To address the problem of difficulty in installing leak-sealing structures, this application provides a leak-sealing device.

[0007] The leak-sealing device provided in this application adopts the following technical solution:

[0008] A leak-sealing device includes a leak-sealing mechanism mounted on a support mechanism. The leak-sealing mechanism comprises a leak-sealing body, a mounting component, and an injection pipe. The mounting component is disposed on the outer surface of the leak-sealing body. A first end of the injection pipe is disposed on the mounting component to form an injection port. A second end of the injection pipe is connected to the interior of the leak-sealing body. The support mechanism is spaced at a predetermined distance from the injection port. The leak-sealing device is used to seal leaks in the leak-sealing mechanism. The leak-sealing device includes: a mounting mechanism detachably connected to the mounting component, the mounting mechanism covering the outer periphery of the injection port, and the mounting mechanism having a cavity for accommodating the injection port. One side of the cavity mates with the mounting component, and the lower side of the cavity mates with the outer surface of the leak-sealing body. The mounting component and the leak-sealing body can close the cavity, so that the injection port is sealed within the cavity; and a clamping mechanism connected to the support mechanism. The installation mechanism includes a clamping mechanism located on the side of the installation mechanism away from the leak-sealing mechanism. The clamping mechanism includes a connecting component, a driving component, and a clamping member with an inclined portion. The connecting component is connected to the installation mechanism, and the driving component is located on the connecting component. The lower side of the clamping member away from the inclined portion cooperates with the installation mechanism. The inclined portion causes the two ends of the clamping member to be a large end away from the support mechanism and a small end close to the support mechanism, respectively. The cross-sectional area of ​​the large end is larger than that of the small end. The driving component is connected to the clamping member for driving the clamping member to move. When the inclined portion of the clamping member cooperates with the support mechanism, and the driving component pushes the clamping member to move towards the support mechanism, the clamping member presses the installation mechanism towards the leak-sealing mechanism, so that the leak-sealing mechanism cooperates with the installation mechanism to seal the cavity.

[0009] By adopting the above technical solution, the installation mechanism can detachably connect to the installation component and cover the outer periphery of the injection port. Its cavity can accommodate the injection port, and one side of the cavity cooperates with the installation component, while the lower side cooperates with the outer surface of the body to be plugged. This allows the installation component and the body to be plugged to seal the cavity, enclosing the injection port inside and achieving a sealing effect on the injection port, preventing liquid inside the body to be plugged from flowing out of the cavity. The connecting component of the clamping mechanism is connected to the installation mechanism, and the drive component is located on the connecting component and drives the clamping component with an inclined part. When the drive component pushes the clamping component to move closer to the support mechanism, the inclined part of the clamping component cooperates with the support mechanism, which can achieve the clamping of the installation mechanism closer to the body to be plugged, further making the body to be plugged and the installation mechanism closely cooperate, enhancing the sealing effect of the cavity, thereby better achieving the purpose of plugging the body to be plugged. By reasonably utilizing the situation where the support mechanism is prone to interference with the plugging device, the cooperation of the wedge-shaped clamping component with the support mechanism is used to improve the plugging effect.

[0010] Optionally, the mounting mechanism includes a cover and a first connecting member. The cover is disposed around the outer periphery of the injection port. One side of the cover is used to cooperate with the mounting member, and the lower end of the cover is used to cooperate with the outer surface of the leak-sealing mechanism. The mounting member is provided with a first mounting hole, and the cover is provided with a second mounting hole. The first connecting member passes through the first mounting hole and the second mounting hole to detachably connect the leak-sealing mechanism and the cover, so that the cover can be relatively fixed to the leak-sealing mechanism.

[0011] By adopting the above technical solution, the cover is placed around the injection port, with one side cooperating with the mounting component and the lower end cooperating with the outer surface of the mechanism to be plugged, thus providing protection and sealing for the injection port. The first mounting hole of the mounting component and the second mounting hole of the cover allow the first connecting component to pass through. The first connecting component detachably connects the mechanism to be plugged and the cover, allowing the cover and the mechanism to be plugged to be relatively fixed, ensuring the stability of the cover installation, and thus better plugging the injection port of the mechanism to be plugged.

[0012] Optionally, the installation mechanism includes a sealing element surrounding the circumference of the injection port, with both ends of the sealing element abutting against the installation element, the upper end of the sealing element connecting to the lower end of the cover, and the lower end of the sealing element extending out of the cover for fitting against the outer surface of the body to be plugged, and the clamping element enabling the sealing element to be tightly pressed against the outer surface of the body to be plugged.

[0013] By adopting the above technical solution, the sealing element surrounds the circumference of the injection port, with its two ends abutting against the mounting component, its upper end connecting to the lower end of the cover, and its lower end extending out of the cover and fitting against the outer surface of the body to be plugged, thus preventing material leakage from the injection port. The clamping component acts on the sealing element, ensuring a tight seal between the sealing element and the outer surface of the body to be plugged, further enhancing the sealing effect, effectively preventing material leakage, and achieving reliable leak plugging of the mechanism to be plugged.

[0014] Optionally, the connecting assembly includes a connecting seat and a second connecting member. The connecting seat is located on the side of the cover away from the body to be sealed. The second connecting member connects the cover and the connecting seat. The clamping member is located on the side of the connecting seat near the support mechanism. The driving assembly is connected to the connecting seat and is throttle-connected to the large end of the clamping member. The small end of the clamping member is located near the support mechanism. The driving assembly pushes the clamping member to move closer to the support mechanism. The support mechanism cooperates with the inclined portion, so that the movement of the clamping member toward the support mechanism can be converted into downward pressure on the cover, so that the sealing member and the body to be sealed fit tightly.

[0015] By adopting the above technical solution, the connecting seat is located on the side of the cover away from the body to be plugged. The second connecting member connects the cover and the connecting seat together, forming a stable connection structure. The clamping member is located on the side of the connecting seat near the support mechanism. The drive assembly is connected to the connecting seat and drives the large end of the clamping member, pushing it towards the support mechanism. Because the clamping member has an inclined portion and its small end is close to the support mechanism, the support mechanism cooperates with the inclined portion, converting the movement of the clamping member towards the support mechanism into downward pressure on the cover. When the cover is pressed down, the sealing member can fit tightly with the body to be plugged, thereby achieving a reliable seal around the injection port of the body to be plugged, achieving the purpose of plugging the leak. Furthermore, this structure is compact and suitable for use in confined spaces.

[0016] Optionally, the drive assembly includes a drive member and a pusher member. The drive member passes through the connecting seat, and the pusher member is sandwiched between the connecting seat and the clamping member. The drive member can drive the pusher member to move, and the pusher member is used to push the clamping member to move closer to the support mechanism.

[0017] By adopting the above technical solution, the driving component in the driving assembly is inserted through the connecting seat, and can be installed and positioned with the help of the connecting seat. The driving component drives the pushing component to move. The pushing component is clamped between the connecting seat and the pressing component, which can transmit the power of the driving component to the pressing component, push the pressing component to move towards the support mechanism, and then use the inclined part to make the pressing component press the installation mechanism towards the mechanism to be plugged, thereby realizing the plugging of the mechanism to be plugged.

[0018] Optionally, the pushing member has a protrusion on the side facing the pressing member, and the pressing member has a groove on the side facing the pushing member, with the protrusion engaging with the groove.

[0019] By adopting the above technical solution, the protrusion on the pushing component and the groove on the clamping component cooperate, enabling the pushing component to accurately push the clamping component to move, thereby achieving a positioning function, avoiding deviation during the pushing process, ensuring that the clamping component moves stably towards the support mechanism, and thus enabling the clamping component to press the installation mechanism towards the leak-to-be-plugged mechanism, ensuring a tight fit between the leak-to-be-plugged mechanism and the installation mechanism, and achieving effective sealing of the injection port.

[0020] Optionally, the side of the protrusion facing the clamping member is an arc surface, and the shape of the groove matches the shape of the protrusion.

[0021] By adopting the above technical solution, the arc design of the protrusion facing the clamping part can ensure uniform force distribution, reduce stress concentration, and improve reliability when it is matched with the groove. The shape of the groove matches the shape of the protrusion, which can ensure that the protrusion is accurately embedded in the groove. This ensures that when the driving part moves the pushing part, the pushing part can stably push the clamping part towards the support mechanism, thereby pressing the installation mechanism towards the leak-sealing mechanism, achieving the purpose of sealing the cavity and completing the leak sealing.

[0022] Optionally, the driving member is provided with an external thread, the connecting seat is provided with a threaded hole, and the driving member is screwed into the threaded hole.

[0023] By adopting the above technical solution, the driving component is provided with an external thread, and the connecting seat is provided with a threaded hole. The two are screwed together, and the driving component can be rotated to move axially in the threaded hole, thereby driving the pushing component to move. The pushing component pushes the pressing component to move closer to the support mechanism, thereby pressing the installation mechanism closer to the leak-sealing mechanism, so that the leak-sealing mechanism cooperates with the installation mechanism to seal the cavity and achieve the purpose of leak sealing.

[0024] Optionally, the lower side of the clamping member is provided with a mating cavity, the shape of which matches the upper surface of the cover, so that the clamping member can be placed on the cover and can slide relative to the cover.

[0025] By adopting the above technical solution, the mating cavity on the lower side of the clamping member is shaped to match the upper surface of the cover, allowing the clamping member to be stably placed on the cover. The design of the mating cavity ensures the fit between the clamping member and the cover. When the drive assembly pushes the clamping member to move, the mating cavity allows the clamping member to slide smoothly relative to the cover along the upper surface of the cover. This ensures that the clamping member can accurately press the installation mechanism towards the leak-sealing mechanism, helping to achieve a tight fit between the leak-sealing mechanism and the installation mechanism to seal the cavity and achieve a better leak-sealing effect.

[0026] Optionally, the cover is provided with an injection port, and the injection port is detachably connected to a sealing element.

[0027] By adopting the above technical solution, the glue injection port provided on the cover can be used to inject sealant into the cavity formed by the cover and the leak-stopping mechanism, further enhancing the leak-stopping effect; the detachable sealing component of the glue injection port can seal the glue injection port, protect the threads on the cover, prevent sealant from overflowing or external impurities from entering, and ensure the sealing performance and reliability of the leak-stopping device.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The cavity where the injection port is located is sealed by the cooperation of the installation mechanism and the mechanism to be plugged. At the same time, the clamping mechanism pushes the clamping part to squeeze the installation mechanism, so that the curved surface of the installation mechanism and the mechanism to be plugged comes into contact, thereby achieving the purpose of plugging the leak.

[0030] 2. The leak-sealing device has a compact structure, making it suitable for leak sealing in confined spaces and meeting the needs of leak sealing in spherical fuel storage devices with extremely limited operating space;

[0031] 3. The clamping component is designed in a wedge shape with an inclined section, which can achieve the effect of squeezing and sealing leaks according to the actual space size, making it more applicable. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0044] like Figure 1 and Figure 2 As shown in the figure, this application discloses a leak-sealing device (hereinafter referred to as "the device"). The device includes an installation mechanism 1 and a pressing mechanism 2, which are used to seal leaks in the mechanism to be sealed.

[0045] like Figure 2 and Figure 3 As shown, the leak-sealing mechanism is mounted on a support mechanism (not shown in the figure). The leak-sealing mechanism includes a leak-sealing body 110, a mounting component 120, and an injection pipe 130. The mounting component 120 is located on the outer surface of the leak-sealing body 110. The first end of the injection pipe 130 is located on the mounting component 120 to form an injection port, and the second end of the injection pipe 130 is connected to the interior of the leak-sealing body 110 to enable material injection. The support mechanism is positioned at a preset distance from the injection port. It should be noted that only a portion of the spherical leak-sealing body 110 is shown in the attached figure to illustrate its relationship with the device.

[0046] like Figure 2 , Figure 4 and Figure 5 As shown, the mounting mechanism 1 is detachably connected to the mounting component 120, and the mounting mechanism 1 covers the outer periphery of the injection port. The mounting mechanism 1 has a cavity 11 for accommodating the injection port. One side of the cavity 11 mates with the mounting component 120, and the lower side of the cavity 11 mates with the outer surface of the body 110 to be plugged. The mounting component 120 and the body 110 to be plugged can seal the cavity 11, so that the injection port is sealed inside the cavity 11, preventing the material inside the body 110 to be plugged from flowing out of the cavity 11.

[0047] like Figure 2 , Figure 4 and Figure 5 As shown, the clamping mechanism 2 is connected to the mounting mechanism 1, and is located on the side of the mounting mechanism 1 away from the leak-sealing mechanism. The clamping mechanism 2 includes a connecting assembly 21, a driving assembly 22, and a clamping member 23 with an inclined portion 231. The connecting assembly 21 is connected to the mounting mechanism 1, the driving assembly 22 is mounted on the connecting assembly 21, and the lower side of the clamping member 23 away from the inclined portion 231 cooperates with the mounting mechanism 1. The inclined portion 231 makes the two ends of the clamping member 23 respectively a large end away from the support mechanism and a small end close to the support mechanism. The cross-sectional area of ​​the large end is larger than that of the small end, making the clamping member 23 have a wedge-shaped structure. The driving assembly 22 is connected to the clamping member 23 for driving the clamping member 23 to move. The inclined portion 231 of the clamping member 23 cooperates with the support mechanism, so that when the drive assembly 22 pushes the clamping member 23 to move closer to the support mechanism, the wedge-shaped clamping member 23 can press the installation mechanism 1 closer to the leak-sealing mechanism, that is, the movement along the tangential direction of the surface of the leak-sealing body 110 is converted into the radial movement along the leak-sealing body 110, so that the leak-sealing mechanism cooperates with the installation mechanism 1 to seal the cavity 11, thereby sealing the injection port in the cavity 11 to achieve leak sealing and prevent leakage.

[0048] When the drive assembly 22 pushes the clamping member 23 towards the support mechanism, the inclined portion 231 of the wedge-shaped clamping member 23 abuts against the support mechanism. The small end of the clamping member 23 continuously squeezes into the lower side of the support mechanism, thus interfering with the support mechanism and pressing the installation mechanism 1 towards the leak-sealing device. This ensures a tight fit between the leak-sealing device and the installation mechanism 1, enhancing the sealing effect on the cavity 11 and better achieving the leak-sealing purpose. This device effectively utilizes the interference problem between the support mechanism and the leak-sealing device, employing a wedge-shaped clamping member 23 in conjunction with the support mechanism to improve the leak-sealing effect. Compared to welding, this device eliminates the need for welding the leak-sealing device, offering better applicability and reducing damage to the thermal insulation material of the support mechanism caused by welding, thereby improving reliability.

[0049] like Figure 1 and Figure 2As shown, the mounting mechanism 1 includes a cover 12 and a first connecting member 13. The cover 12 covers the outer periphery of the injection port, and the clamping member 23 is located on the side of the cover 12 away from the body 110 to be plugged. One side of the cover 12 is used to cooperate with the mounting member 120, and the lower end of the cover 12 is used to cooperate with the outer surface of the mechanism to be plugged, so that the cover 12 can form a protective and sealing effect on the injection port. The mounting member 120 is provided with a first mounting hole 150, and the cover 12 is provided with a second mounting hole 121. The first connecting member 13 passes through the first mounting hole 150 and the second mounting hole 121, and is used to detachably connect the mechanism to be plugged and the cover 12, so that the cover 12 can be relatively fixed with the mechanism to be plugged, ensuring the stability of the cover 12 installation, thereby better plugging the injection port of the mechanism to be plugged. Specifically, the first mounting hole 150 and the second mounting hole 121 can both be threaded holes. The injection port can be initially plugged with bolts or other plugs 140, and then this device can be used to further plug the leak and improve the plugging effect.

[0050] like Figure 2 , Figure 5 and Figure 6 As shown, the lower side of the clamping member 23 is provided with a mating cavity 233. The shape of the mating cavity 233 matches the upper surface of the cover 12, ensuring the fit between the clamping member 23 and the cover 12, allowing the clamping member 23 to be stably placed on the cover 12. The clamping member 23 can slide relative to the cover 12, so that when the drive assembly 22 pushes the clamping member 23 to move, the mating cavity 233 allows the clamping member 23 to slide smoothly relative to the cover 12 along the upper surface of the cover 12. The clamping member 23 is initially limited by the support mechanism, so that the clamping member 23 can be stably placed on the cover 12, thereby ensuring that when the drive assembly 22 pushes the clamping member 23, it can accurately press the mounting mechanism 1 towards the leak-sealing mechanism, which helps to achieve a tight fit between the leak-sealing mechanism and the mounting mechanism 1 to seal the cavity 11, achieving a better leak-sealing effect.

[0051] like Figure 1 , Figure 2 and Figure 5 As shown, optionally, the housing 12 is provided with an injection port 122, which can be used to inject sealant into the cavity 11 formed by the housing 12 and the leak-sealing mechanism to further enhance the leak-sealing effect. The injection port 122 is detachably connected to a sealing member 15, which can seal the injection port 122, protect the threads on the housing 12, prevent sealant from overflowing or external impurities from entering, and ensure the sealing performance and reliability of the leak-sealing device.

[0052] like Figure 1 and Figure 2As shown, the mounting mechanism 1 includes a sealing element 14. The sealing element 14 surrounds the circumference of the injection port, and both ends of the sealing element 14 abut against the mounting element 120. The first connecting element 13 enables the sealing element 14 to be tightly abutted against the mounting element 120. The upper end of the sealing element 14 is connected to the lower end of the cover 12, and the lower end of the sealing element 14 extends out of the cover 12 to fit against the outer surface of the body 110 to be plugged, preventing material leakage from the injection port. The clamping element 23 acts on the sealing element 14 through the cover 12, enabling the sealing element 14 to abut against the outer surface of the body 110 to be plugged, further enhancing the sealing effect, effectively preventing material leakage, and achieving reliable plugging of the leak-prone mechanism. Specifically, the outer surface of the body 110 to be plugged, the lower side of the cover 12, and the lower side of the sealing element 14 are all curved surfaces that can fit together; the material, shape, and other parameters of the sealing element 14 can be set as needed.

[0053] like Figure 1 and Figure 2 As shown, the connecting assembly 21 includes a connecting seat 211 and a second connecting member 212. The connecting seat 211 is located on the side of the cover 12 away from the body 110 to be plugged. The second connecting member 212 connects the cover 12 and the connecting seat 211, forming a stable connection structure. The driving assembly 22 is connected to the connecting seat 211. The clamping member 23 is located on the side of the connecting seat 211 near the support mechanism. The driving assembly 22 drives the large end of the clamping member 23, and the small end of the clamping member 23 is located near the support mechanism. The driving assembly 22 pushes the clamping member 23 towards the support mechanism. The support mechanism cooperates with the inclined part 231, so that the movement of the clamping member 23 towards the support mechanism can be converted into downward pressure on the cover 12 by the inclined part 231, so that the sealing member 14 and the body 110 to be plugged fit tightly, thereby achieving reliable sealing of the outer periphery of the injection port of the body to be plugged, achieving the purpose of plugging the leak. Moreover, this structure is compact and suitable for use in confined spaces.

[0054] like Figure 1 and Figure 2 As shown, the drive assembly 22 includes a drive member 221 and a pusher member 222. The drive member 221 passes through the connecting seat 211 and can be installed and positioned using the connecting seat 211. The pusher member 222 is clamped between the connecting seat 211 and the clamping member 23. The drive member 221 can drive the pusher member 222 to move, transmitting the power of the drive member 221 to the clamping member 23. The pusher member 222 is used to push the clamping member 23 towards the support mechanism, and then, through the inclined portion 231, the clamping member 23 presses the mounting mechanism 1 towards the mechanism to be plugged, thereby achieving the plugging of the leak in the mechanism to be plugged. This device can convert the movement along the length direction of the drive member 221 into movement along the length direction of the second connecting member 212, reducing damage to the mechanism to be plugged and the support mechanism, while also reducing the difficulty of operation.

[0055] like Figure 1 , Figure 2 and Figure 5 As shown, the driving component 221 has an external thread, and the connecting seat 211 has a threaded hole. The driving component 221 is screwed into the threaded hole, allowing it to move axially within the threaded hole by rotation. This, in turn, drives the pushing component 222 to move. The pushing component 222 pushes the clamping component 23 towards the support mechanism, thereby pressing the mounting mechanism 1 towards the leak-sealing mechanism. This allows the leak-sealing mechanism to cooperate with the mounting mechanism 1 to seal the cavity 11, achieving the purpose of leak sealing. The threaded hole is a through-hole, allowing the driving component 221 on one side of the connecting seat 211 to pass through the connecting seat 211 and cooperate with the pushing component 222 on the other side of the connecting seat 211. A threaded blind hole can be provided on the side of the pushing component 222 facing the driving component 221 for screwing into the driving component 221, so that the driving component 221 can reliably drive the pushing component 222 to push the clamping component 23 towards the support mechanism. It is understandable that the first connector 13, the second connector 212, the driving component 221, and the sealing component 15 can all be screw or bolt structures, and threaded holes are provided at corresponding positions to enable connection.

[0056] like Figure 1 , Figure 2 and Figure 6 As shown, the pushing member 222 has a protrusion 223 on the side facing the pressing member 23, and the pressing member 23 has a groove 232 on the side facing the pushing member 222. The protrusion 223 and the groove 232 cooperate to enable the pushing member 222 to accurately push the pressing member 23 to move, thereby achieving a positioning function, avoiding deviation during the pushing process, and ensuring that the pressing member 23 moves stably towards the support mechanism. In turn, the pressing member 23 presses the installation mechanism 1 towards the leak-sealing mechanism, ensuring a tight fit between the leak-sealing mechanism and the installation mechanism 1, and achieving effective sealing of the injection port.

[0057] like Figure 2 , Figure 5 and Figure 6 As shown, the side of the protrusion 223 facing the clamping member 23 is arc-shaped, and the shape of the groove 232 matches the shape of the protrusion 223. This design ensures uniform force distribution, reduces stress concentration, and improves reliability when the protrusion 223 is engaged with the groove 232. This design ensures that the protrusion 223 is accurately embedded in the groove 232, and that when the driving member 221 moves the pushing member 222, the pushing member 222 can stably push the clamping member 23 towards the support mechanism. This allows the clamping member 23 to press the mounting mechanism 1 towards the leak-sealing mechanism, thereby sealing the cavity 11 and completing the leak-sealing purpose.

[0058] It is understandable that the device also includes necessary structures for connection, support, drive, positioning, limiting and sealing functions, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.

[0059] The implementation principle of the leak-sealing device in this application embodiment is as follows: The installation mechanism 1 is detachably connected to the installation component 120 and covers the outer periphery of the injection port. One side of its cavity 11 cooperates with the installation component 120, and the lower side cooperates with the outer surface of the body 110 to be leak-sealed. The installation component 120 and the body 110 to be leak-sealed close the cavity 11, sealing the injection port inside the cavity 11, thus achieving preliminary sealing. The connecting component 21 of the clamping mechanism 2 is connected to the installation mechanism 1. The driving component 22 is disposed on the connecting component 21 and is connected to the clamping component 23 with an inclined surface. When the driving component 22 pushes the clamping component 23 to move closer to the support mechanism, since the inclined surface of the clamping component 23 cooperates with the support mechanism, and the cross-sectional areas of the two ends of the clamping component 23 are different, with the larger end away from the support mechanism and the smaller end closer to the support mechanism, the clamping component 23 presses the installation mechanism 1 closer to the body to be leak-sealed, further enhancing the cooperation between the body to be leak-sealed and the installation mechanism 1, thereby more effectively sealing the cavity 11 and achieving the purpose of leak sealing of the body to be leak-sealed.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
