Description

Technical Field

[0001] This application belongs to the field of battery technology, specifically relating to a housing with a seal, a battery, and an electrical device. Background Technology

[0002] With the increasing maturity of new energy technologies, batteries are being used in various industries, and people's requirements for the sealing and protection of batteries are gradually increasing.

[0003] In prior art, the separate design of the battery casing usually includes a sealing element to ensure the airtightness of the battery casing.

[0004] However, the assembly efficiency of medium and large-sized sealing rings is usually low due to their large size. Furthermore, there is a risk of seal failure due to incorrect assembly orientation. Utility Model Content

[0005] The purpose of this application is to provide a housing, battery, and electrical device with a seal that can solve at least some of the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, embodiments of this application provide a housing with a seal, including a first housing, a second housing, and a seal. The first housing and the second housing are detachably connected, and the seal is disposed between the first housing and the second housing. The seal includes at least a first positioning structure, a second positioning structure, and a body. The first positioning structure and the second positioning structure are connected to the body. The first housing includes at least a first positioning element and a second positioning element. The positioning element is disposed on the side of the first housing facing the second housing. The first positioning structure and the first positioning element are correspondingly disposed and adapted to each other, and the second positioning structure and the second positioning element are correspondingly disposed and adapted to each other. One of the first positioning structure and the second positioning structure is provided with a first foolproof part, and one of the first positioning element and the second positioning element is provided with a second foolproof part. The first foolproof part and the second foolproof part are adapted to each other.

[0007] In this embodiment, one of the first and second positioning structures is provided with a first misalignment part. It is understood that the first and second positioning structures are asymmetrically designed, and together with the cooperative operation of the first misalignment part, they constitute a structural component that ensures precise and efficient assembly. In practical applications, during assembly, the seal is placed between the detachably connected first and second housings. The key lies in the fitting relationship between the first and second positioning structures on the seal and the first and second positioning elements on the first housing. Because the first and second positioning structures are asymmetrically designed, this means that they differ in shape, size, or positional layout. For example, the first misalignment part may be a raised columnar structure, while the second misalignment part is a grooved structure whose shape and size do not match. Furthermore, the distribution of the first and second positioning structures on the seal body is not symmetrical. This asymmetry means that the first positioning structure can only fit with the first positioning element, and the second positioning structure can only correspondingly cooperate with the second positioning element, in a specific orientation. Meanwhile, one of the first positioning structure and the second positioning structure is provided with a first anti-misalignment part, and one of the first positioning member and the second positioning member is provided with a second anti-misalignment part, and the two are mutually compatible. Taking the first anti-misalignment part as a protrusion protruding away from the body and the second anti-misalignment part as a corresponding groove as an example, the first anti-misalignment part can be smoothly inserted into the second anti-misalignment part only when the seal is in the correct assembly direction, thereby completing the initial positioning of the seal and the first housing. If the seal is oriented incorrectly, the asymmetrical positioning structure cannot match, and the anti-misalignment part cannot cooperate properly. The assembler will clearly feel the resistance during operation, and then promptly discover and correct the assembly direction to ensure that the seal is installed between the two housings in the correct posture. From the perspective of beneficial effects, the above-mentioned setup brings significant technical advantages. On the one hand, it greatly improves assembly efficiency. In the assembly of traditional symmetrical seals, due to the lack of clear directional markings, assemblers often need to repeatedly try and compare to determine the correct assembly direction, which not only prolongs assembly time but also increases labor costs. However, this application, through the asymmetrical setup of the first and second positioning structures, allows assemblers to quickly determine the correct assembly direction of the seal based on structural differences, reducing invalid attempts and making the assembly process smoother and more efficient. This enables rapid advancement of assembly line operations and significantly improves production efficiency. On the other hand, it effectively avoids incorrect seal assembly direction. Once the seal assembly direction is incorrect, the seal cannot fit tightly against the shell, thereby reducing sealing performance and significantly compromising the shell's waterproof, dustproof, and gas-proof functions. In applications such as batteries, sealing failure may lead to moisture absorption and short circuits in the battery cells, affecting battery life and even causing safety hazards. In electrical equipment, sealing problems can also damage internal components, reducing equipment stability and reliability. This application, through its asymmetrical design, eliminates the possibility of incorrect assembly direction from the outset, ensuring that the seals perform optimally, guaranteeing the overall performance and quality of the product, reducing the product defect rate and after-sales maintenance costs, enhancing the product's market competitiveness, and creating good economic benefits and brand value for the enterprise.

[0008] It should be noted that the first and second positioning components can be bolts with guide angles at the ends, with the guide angles ranging from 5° to 20°.

[0011] Optionally, in this embodiment of the application, the straight-line distance between the first positioning structure and the second positioning structure is greater than or equal to the straight-line distance between any two points on the seal.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0022] The following description, in conjunction with the accompanying drawings, details the housing and battery with sealing elements provided in this application through specific embodiments and application scenarios.

[0023] See Figures 1 to 3 The embodiments of this application provide a housing with a seal 30, including a first housing 10, a second housing 20 and a seal 30. The first housing 10 and the second housing 20 are detachably connected, and the seal 30 is disposed between the first housing 10 and the second housing 20. The seal 30 includes at least a first positioning structure 31 and a second positioning structure 32 and a body 33. The first positioning structure 31 and the second positioning structure 32 are connected to the body 33. The first housing 10 includes at least a first positioning member and a second positioning member. The positioning member is disposed on the side of the first housing 10 facing the second housing 20. The first positioning structure 31 and the first positioning member are correspondingly disposed and adapted, and the second positioning structure 32 and the second positioning member are correspondingly disposed and adapted. One of the first positioning structure 31 and the second positioning structure 32 is provided with a first anti-fooling part 311, and one of the first positioning member and the second positioning member is provided with a second anti-fooling part. The first anti-fooling part 311 and the second anti-fooling part are adapted to each other.

[0024] In this embodiment, one of the first positioning structure 31 and the second positioning structure 32 is provided with a first misalignment prevention part 311. It is understood that the first positioning structure 31 and the second positioning structure 32 are asymmetrically designed, and their coordinated operation with the first misalignment prevention part 311 constitutes a structural component that ensures accurate and efficient assembly. In practical applications, during assembly, the sealing element 30 is placed between the detachably connected first housing 10 and second housing 20. The key lies in the compatibility between the first positioning structure 31 and the second positioning structure 32 on the sealing element 30 and the first positioning element and the second positioning element on the first housing 10. Because the first positioning structure 31 and the second positioning structure 32 are asymmetrically designed, this means that they differ in shape, size, or positional layout. For example, the first misalignment prevention part 311 may be a protruding columnar structure, while the second misalignment prevention part is a grooved structure whose shape and size do not match. Furthermore, the distribution of the first positioning structure 31 and the second positioning structure 32 on the body 33 of the sealing element 30 is not symmetrical. This asymmetry means that the first positioning structure 31 can only mate with the first positioning member, and the second positioning structure 32 can only mate with the second positioning member, under specific orientations. Simultaneously, one of the first positioning structure 31 and the second positioning structure 32 is provided with a first anti-misalignment part 311, and one of the first positioning member and the second positioning member is provided with a second anti-misalignment part, and the two are mutually compatible. Taking the first anti-misalignment part 311 as a protrusion protruding away from the body 33 and the second anti-misalignment part as a corresponding groove as an example, only when the seal 30 is in the correct assembly orientation can the first anti-misalignment part 311 smoothly engage with the second anti-misalignment part, thereby completing the initial positioning of the seal 30 and the first housing 10. If the seal 30 is oriented incorrectly, the asymmetrical positioning structures cannot match, and the anti-misalignment parts cannot properly engage. The assembler will clearly feel resistance during operation, thus promptly identifying and correcting the assembly orientation to ensure that the seal 30 is installed correctly between the two housings. From the perspective of beneficial effects, the above-mentioned setup brings significant technical advantages. On the one hand, it greatly improves assembly efficiency. In the assembly of traditional symmetrical seals 30, due to the lack of clear directional markings, assemblers often need to repeatedly try and compare to determine the correct assembly direction, which not only prolongs assembly time but also increases labor costs. However, this application, through the asymmetrical setup of the first positioning structure 31 and the second positioning structure 32, allows assemblers to quickly determine the correct assembly direction of the seal 30 based on structural differences, reducing invalid attempts and making the assembly process smoother and more efficient. This enables rapid advancement of assembly line operations and significantly improves production efficiency. On the other hand, it effectively avoids incorrect assembly direction of the seal 30. Once the assembly direction of the seal 30 is incorrect, the seal 30 will not be able to fit tightly against the shell, thereby reducing sealing performance and significantly compromising the waterproof, dustproof, and gasproof functions of the shell. In applications such as batteries, sealing failure may lead to moisture absorption and short circuits in the battery cells, affecting battery life and even causing safety hazards; in electrical equipment, sealing problems may also damage internal components, reducing equipment stability and reliability. This application, through its asymmetrical design, eliminates the possibility of incorrect assembly direction from the outset, ensuring that the seal 30 performs optimally, guaranteeing the overall performance and quality of the product, reducing the product's defect rate and after-sales maintenance costs, enhancing the product's market competitiveness, and creating good economic benefits and brand value for the enterprise.

[0025] It should be noted that the first and second positioning components can be bolts with guide angles at the ends, with the guide angles ranging from 5° to 20°.

[0026] Optionally, in the embodiments of this application, the other of the first positioning structure 31 and the second positioning structure 32 is provided with a third anti-mistake part 321, and the other of the first positioning member and the second positioning member is provided with a fourth anti-mistake part, and the third anti-mistake part 321 and the fourth anti-mistake part are adapted to each other.

[0027] In this embodiment, the other of the first positioning structure 31 and the second positioning structure 32 is provided with a second misalignment. It is understood that the first positioning structure 31 and the second positioning structure 32 are asymmetrically designed. Together with the cooperative operation of the first misalignment 311 and the second misalignment, they constitute a structural component that ensures accurate and efficient assembly. In practical applications, during assembly, the sealing element 30 is placed between the detachably connected first housing 10 and second housing 20. The key lies in the compatibility between the first positioning structure 31 and the second positioning structure 32 on the sealing element 30 and the first positioning element and the second positioning element on the first housing 10. Because the first positioning structure 31 and the second positioning structure 32 are asymmetrically designed, this means that they differ in shape, size, or positional layout.

[0028] It should be noted that the first anti-misalignment part 311 and the third anti-misalignment part 321 have different structures. The first anti-misalignment part 311 may be a raised columnar structure, while the second anti-misalignment part may be a polygonal structure. Furthermore, the first positioning member and the second positioning member are also groove-shaped structures with mismatched shapes and sizes. This asymmetry means that the sealing member 30 can only be engaged with the first positioning structure 31 and the second positioning structure 32 in a specific orientation. The above arrangement has the beneficial effect of facilitating assembly personnel to identify the assembly direction, improving assembly efficiency, and avoiding assembly direction errors.

[0029] Optionally, in this embodiment, the body 33 includes a plurality of annular portions 331, which are spaced apart, and the first positioning structure 31 and the second positioning structure 32 are both spaced apart from the annular portions 331.

[0030] In this embodiment, the multiple spaced annular portions 331 form a multi-layered sealing barrier when the sealing element 30 is assembled with the first housing 10 and the second housing 20. When the first housing 10 and the second housing 20 press against the sealing element 30, the annular portions 331 undergo elastic deformation under pressure, tightly fitting the inner walls of the two housings and effectively filling the gaps between them, preventing external substances such as gas, liquid, or dust from entering the inner cavity of the housing through the gaps. Because the annular portions 331 are spaced apart, a buffer space is formed between adjacent annular portions 331. When subjected to changes in external pressure or slight deformation of the housing, the annular portions 331 can more flexibly adjust elastically, maintaining a good sealing state. At the same time, the first positioning structure 31 and the second positioning structure 32 are spaced apart from the annular portions 331, avoiding interference from the positioning structures on the sealing function of the annular portions 331. The positioning structures are mainly responsible for the precise positioning of the sealing element 30, while the annular portions 331 focus on achieving the sealing effect; the two are independent yet work together. During assembly, the positioning structure ensures that the seal 30 is accurately installed in the predetermined position, laying the foundation for the annular portion 331 to perform its sealing function. With accurate positioning, the annular portion 331 can be evenly stressed and deformed, maximizing the sealing effect. For example, if the positioning structure overlaps with the annular portion 331, it may cause uneven stress on the annular portion 331, affecting the uniformity of its deformation and thus reducing sealing performance. The spaced arrangement effectively avoids this problem. From the perspective of beneficial effects, firstly, it significantly improves the sealing performance of the seal 30. The design of the multiple annular portions 331 is equivalent to setting up multiple sealing barriers. Compared with a single sealing structure, it can more effectively block the intrusion of external substances, greatly improving the waterproof, dustproof, and gas-proof sealing capabilities of the casing. In battery applications, it can effectively prevent electrolyte leakage and the entry of external moisture and gas into the battery, ensuring the safe and stable operation of the cell and extending battery life. In electrical equipment, it can provide a good protective environment for internal components, avoiding component damage caused by the intrusion of external substances, and improving the stability and reliability of the equipment. Secondly, this design enhances the adaptability of the seal 30 to different operating conditions. Due to the buffer space between the annular portions 331 and the reasonable layout with the first positioning structure 31 and the second positioning structure 32, even when the casing is slightly deformed due to factors such as vibration and temperature changes, the seal 30 can still maintain a good sealing effect, broadening the application range of the product, reducing product failures and after-sales problems caused by sealing failure, reducing the maintenance costs of enterprises, and also improving the market competitiveness and user satisfaction of the product. Optionally, in this embodiment, the straight-line distance between the first positioning structure 31 and the second positioning structure 32 is greater than or equal to the straight-line distance between any two points on the seal 30.

[0031] In this embodiment, the maximum spacing between the first positioning structure 31 and the second positioning structure 32 creates a "diagonal" or "limited distribution" layout on the seal 30. For example, when the seal 30 is rectangular, the first positioning structure 31 and the second positioning structure 32 are arranged diagonally; when the seal 30 is circular, the spacing between the first positioning structure 31 and the second positioning structure 32 is the diameter. During assembly, when the seal 30 mates with the first housing 10 and the second housing 20, this layout provides a more stable positioning effect for the seal 30. The larger spacing allows the two limiting structures to constrain the seal 30 over a wider range, reducing the possibility of the seal 30 shifting or twisting between the housings. For example, when installing the seal 30 between the housings, if the spacing between the limiting structures is too small, the seal 30 may easily rotate around a certain point when subjected to compression or external force, causing the seal 30 to fail to properly fit the housing and affecting the sealing effect. When the distance between the first positioning structure 31 and the second positioning structure 32 is large enough, they can form stable support points at different positions of the seal 30, as if they are fixed at both ends or diagonally of the seal 30, so that the seal 30 always maintains the correct posture during the assembly process, and ensures that the sealing structure such as the annular part 331 of the seal 30 can contact the shell evenly and deform, thereby achieving a good seal. From a beneficial perspective, firstly, this design significantly improves the assembly stability of the seal 30. Due to the rational layout of the limiting structure, the seal 30 is less prone to positional deviation during assembly, reducing the risk of seal failure due to improper assembly and improving product yield. In mass production, stable assembly reduces the number of manual calibrations and rework, increasing production efficiency and lowering production costs. Secondly, it ensures the sealing reliability of the seal 30. Stable assembly allows the seal 30 to fully perform its sealing function; the annular portion 331 can deform evenly under stress, tightly fitting the shell and effectively blocking external gases, liquids, and dust, improving the shell's waterproof, dustproof, and gas-proof performance. Whether applied to protect battery cells or internal components in electrical equipment, it provides reliable protection, extends equipment lifespan, enhances operational stability in complex environments, and ultimately improves product market competitiveness and user reputation.

[0032] Optionally, in this embodiment of the application, along the plane where the seal 30 is located, the first anti-mistake part 311 protrudes from the body 33 in a direction away from the body 33, and the second anti-mistake part is a groove that can accommodate the first anti-mistake part 311.

[0033] In this embodiment, during the assembly of the seal 30 with the first housing 10, this concave-convex structure forms a clear assembly guide and direction determination mechanism. When the operator installs the seal 30 onto the first housing 10, the protruding structure of the first anti-misalignment part 311 and the groove structure of the second anti-misalignment part have a unique matching direction. Only when the seal 30 is in the correct assembly direction can the protrusion of the first anti-misalignment part 311 smoothly embed into the groove of the second anti-misalignment part. The precise positioning of the seal 30 in the planar direction is achieved through the fitting relationship between the protrusion and the inner wall of the groove. If the seal 30 is oriented incorrectly, the protrusion of the first anti-misalignment part 311 cannot align with the groove of the second anti-misalignment part, resulting in significant resistance during assembly. The operator can visually perceive the assembly abnormality and adjust the direction of the seal 30 in a timely manner. This structural design utilizes the uniqueness of the physical structure to forcibly regulate the assembly direction of the seal 30, ensuring the accurate installation position of the seal 30 and laying the foundation for a tight fit between the seal 30 and the housing, achieving a good sealing effect. Meanwhile, when the first anti-mistake part 311 is embedded in the groove of the second anti-mistake part, the cooperation between the two can also limit the displacement of the seal 30 in the plane to a certain extent, prevent the seal 30 from sliding or shifting when subjected to external force, and further stabilize the assembly state of the seal 30. From the perspective of beneficial effects, firstly, it significantly reduces the assembly error rate of the seal 30. Through this intuitive and mandatory mistake-proof design, even newly hired or inexperienced operators can quickly and accurately install the seal 30 in the correct position without spending a lot of time and effort judging the assembly direction, effectively avoiding assembly errors caused by human negligence. In large-scale production scenarios, it significantly reduces product defects caused by incorrect seal 30 assembly, improving the first-pass yield rate. Secondly, it effectively ensures the sealing performance of the seal 30. Only when the seal 30 is correctly installed can the sealing structure, such as the annular portion 331, make uniform contact with the shell and fully compress and deform, thereby forming an effective sealing barrier. If the seal 30 is assembled in the wrong direction, it will lead to uneven local stress on the sealing structure, preventing it from tightly fitting the shell and increasing the risk of seal failure. The concave-convex anti-foolproof structure ensures precise installation of the seal 30, enabling it to achieve optimal sealing performance and effectively preventing the intrusion of external gases, liquids, dust, etc. Whether in the battery field to prevent electrolyte leakage and the entry of external substances, or in the field of electrical equipment to protect internal precision components from the influence of the external environment, it provides a solid guarantee for the performance and reliability of the product, reduces after-sales maintenance costs, and enhances the product's market competitiveness.

[0034] Optionally, in this embodiment, along the plane of the seal 30, the third anti-mistake part 321 protrudes from the body 33 in a direction away from the body 33, and the fourth anti-mistake part is a groove that can accommodate the third anti-mistake part 321.

[0035] In this embodiment, during the assembly of the seal 30 with the first housing 10, the interlocking of the third anti-misalignment part 321 and the fourth anti-misalignment part forms a multi-dimensional anti-misalignment constraint. When the seal 30 approaches the first housing 10, not only must the first anti-misalignment part 311 and the second anti-misalignment part precisely fit together, but the protruding structure of the third anti-misalignment part 321 must also be aligned with the groove structure of the fourth anti-misalignment part in a specific direction to achieve proper fit. These two sets of anti-misalignment structures limit the assembly direction of the seal 30 from different angles, further reducing the range of possible incorrect assembly angles of the seal 30. For example, with only the first and second anti-misalignment parts, the seal 30 may be installed in a 180° reverse orientation within the plane. However, with the addition of the third and fourth anti-misalignment parts, the seal 30 can only be accurately embedded simultaneously in the only correct orientation, achieving dual positioning. This design, through multi-dimensional constraints between physical structures, forces the seal 30 to be installed onto the first housing 10 in a precise orientation. Meanwhile, once both sets of anti-foolproof structures are assembled, the tight fit between the protrusion and the groove can form multiple stable support points in the plane, effectively limiting the displacement and rotation of the seal 30, ensuring that the seal 30 maintains a stable installation state during subsequent housing assembly and use, and providing a reliable foundation for the seal 30 to perform its sealing function. From the perspective of beneficial effects, firstly, it significantly improves the accuracy and stability of the assembly of the seal 30. The design of the double-proof structure greatly reduces the possibility of assembly errors of the seal 30, ensuring the correct installation orientation of the seal 30 even in complex production environments or high-intensity assembly operations. For automated assembly lines, this design reduces equipment downtime for adjustment due to seal 30 assembly errors, improving production efficiency; for manual assembly, it further simplifies the operation process and lowers the skill threshold for operators, allowing even workers without extensive training to quickly master the correct assembly method. Secondly, it significantly enhances the sealing reliability of the seal 30. Only when the seal 30 is installed in a precise orientation can its annular portion 331 and other sealing structures fully fit the shell, deforming uniformly under pressure to form a complete sealing barrier. The synergistic effect of the third and fourth proof-of-failure mechanisms with the first and second proof-of-failure mechanisms ensures that the seal 30 will not experience local sealing failure due to assembly deviations, effectively preventing the intrusion of external substances. In battery applications, it can comprehensively prevent electrolyte leakage and the ingress of external moisture, ensuring the safe and stable operation of the battery cell; in electrical equipment, it can provide more reliable protection for internal precision components, reduce equipment failures caused by sealing problems, extend equipment life, reduce after-sales maintenance costs for enterprises, and at the same time enhance the product's competitiveness in the market and user trust.

[0036] Optionally, in this embodiment of the application, the first housing 10 is provided with a first receiving groove on the side facing the second housing 20, and the sealing member 30 can be accommodated in the first receiving groove.

[0037] In this embodiment, the first receiving groove provides a precise installation and positioning space for the seal 30. During assembly, the seal 30 can be embedded in the first receiving groove, the shape and size of which are adapted to the seal 30, allowing the seal 30 to be quickly positioned during installation and reducing adjustment time during assembly. This embedded design is equivalent to setting a "positioning frame" for the seal 30. When the first housing 10 and the second housing 20 are connected, the seal 30 is confined within the first receiving groove, preventing lateral or longitudinal displacement and ensuring that the seal 30 is always in the correct sealing position between the two housings. Furthermore, when the upper and lower housings 20 are pressed together, the groove wall of the first receiving groove can support the seal 30, making the force on the seal 30 more even. When the seal 30 is compressed, it will undergo elastic deformation within the first receiving groove, and the groove wall will fit tightly against the seal 30, further preventing external gases, liquids, or dust from entering the housing cavity through the gap between the seal 30 and the housing, effectively improving the sealing effect.

[0038] Optionally, in this embodiment, the second housing 20 has a second receiving groove on the side facing the first housing 10, and the body 33 can be accommodated in the second receiving groove along the height direction of the housing with the seal.

[0039] In this embodiment, the second receiving groove provides a dedicated installation space for the body 33 in a direction perpendicular to the plane of the seal 30. During assembly, the body 33 of the seal 30 is embedded in the second receiving groove, and the depth and shape of the groove are precisely matched with the body 33 of the seal 30, forming a longitudinal positioning reference. When the upper second housing 20 is assembled, the body 33 of the seal 30 is firmly confined within the second receiving groove, effectively preventing the seal 30 from being misaligned, tilted, or moving up and down in the height direction of the housing. At the same time, the groove wall of the second receiving groove can help distribute the pressure on the seal 30 when the housing is closed. When the upper second housing 20 is pressed against each other, while the seal 30 is deformed under force in the horizontal direction, the groove wall of the second receiving groove will apply a reverse supporting force to the body 33 of the seal 30, so that the seal 30 can also remain stable in the height direction, causing the sealing structure such as the annular portion 331 of the seal 30 to fit more evenly with the upper second housing 20, further enhancing the sealing effect. For example, without the second receiving groove, the seal 30 lacks effective constraint in the height direction of the housing, which may cause uneven force to result in the annular portion 331 being unable to make tight contact with the housing, thus creating a sealing gap. The presence of the second receiving groove avoids this problem. From the perspective of beneficial effects, firstly, it greatly improves the stability and reliability of the assembly of the seal 30. The second receiving groove works together with the first receiving groove to construct a three-dimensional positioning system, enabling the seal 30 to be accurately positioned in three-dimensional space. Whether assembled manually or on an automated production line, the installation of the seal 30 can be completed quickly and accurately, reducing product quality problems caused by improper installation of the seal 30 and improving the first-pass yield. In mass production, the stable assembly effect helps to improve production efficiency and reduce production costs. Secondly, it significantly enhances the sealing performance of the seal 30.
