For the ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific situation.

[0023] Please refer to Figures 1 to 3 , it is a side sealing device of an embodiment of the utility model, which is used for the air tightness test of products, the side sealing device comprises a fixing assembly 10 and a sealing assembly 20 mounted on the fixing assembly 10 for the air tightness test of products, the sealing assembly 20 comprises a driving piece 21 mounted on the fixing assembly 10, a support plate 22 mounted on the free end of the driving piece 21, an elastic piece 23 mounted on the support plate 22, and a sealing piece 24 mounted on the free end of the elastic piece 23, the driving piece 21 is used for driving the support plate 22 to drive the elastic piece 23 and the sealing piece 24 to move towards the product, so as to drive the sealing piece 24 to tightly close and block the opening of the product, and compress the elastic piece 23, so as to make the elastic piece 23 provide a rebound force after being compressed to further strengthen the tight pressing force of the sealing piece 24 on the product.

[0024] The working principle of the side sealing device is as follows: when the product is placed in the testing position, the driving part 21 pushes the supporting plate 22 to move towards the opening direction of the product; at this time, the elastic part 23 has not been deformed obviously, and the sealing part 24 begins to gradually approach the opening of the product; with the continuous movement of the driving part 21, the sealing part 24 contacts the side opening of the product; at this time, the driving part 21 continues to exert pressure to make the elastic part 23 start to compress; the elastic force of the elastic part 23 increases with the increase of the compression degree, and this force acts on the sealing part 24, so that the sealing part 24 tightly fits the edge of the opening of the product; under the action of the testing gas pressure, the sealing part 24 is subjected to an outward thrust, but due to the elastic force of the elastic part 23, the sealing part 24 can continue to maintain the sealing state to realize the sealing of the product; after the air tightness test is completed, the driving part 21 moves reversely to make the sealing part 24 leave the side opening of the product; at this time, the elastic part 23 restores to the original state under the action of the elastic restoring force; the driving part 21, the supporting plate 22 and the sealing part 24 return to the initial position to prepare for the next air tightness test of the product.

[0025] Compared with the prior art, the side sealing device of the utility model, the existence of the elastic part 23 makes the sealing part 24 be able to adapt to the unevenness of the surface of the side opening of the product; the sealing part 24 tightly fits the opening, effectively prevents the gas leakage, thereby guaranteeing the accuracy of the air tightness test result; during the testing process, when the product is filled with gas and the pressure rises, the elastic part 23 can provide continuous pressure compensation; under the joint action of the elastic force and the internal gas pressure, the sealing part 24 can still maintain a good sealing state, avoiding the sealing failure caused by the pressure change; the process that the driving part 21 drives the sealing part 24 to approach the side opening of the product is a gradual and elastic buffering process; compared with the rigid sealing device, the device will not cause damage to the product due to the sudden impact force when contacting the product; the fixed assembly 10 provides a stable basis for the whole sealing process, the driving part 21 moves along the fixed guide structure, ensuring that the sealing part 24 can be accurately positioned to the position of the side opening of the product; avoiding the sealing conditions of each test being consistent, reducing the test error, improving the repeatability and reliability of the test result.

[0026] Please refer to Figure 1 and Figure 2, the two drive members 21 of the two blocking assemblies 20 are respectively arranged obliquely upward and obliquely downward. The two drive members 21 of the two blocking assemblies 20 are respectively arranged obliquely upward and obliquely downward mainly to adapt to the case that the product has openings with different directions or complex shapes on the side. For example, when the product has an upwardly oblique opening and a downwardly oblique opening on the side, the obliquely arranged blocking assemblies 20 can better align the openings for blocking. After the product is placed in the test position, the drive device starts the drive members 21 of the two blocking assemblies 20. The drive member 21 arranged obliquely upward moves obliquely upward along the guide structure on the fixed assembly 10 toward the opening direction of the product, and the drive member 21 arranged obliquely downward moves obliquely downward. The support plates 22 at the free ends of the two drive members 21 also move with the drive members 21 and start to transmit the driving force to the respective elastic members 23. Since the opening is oblique, the elastic member 23 can adaptively compensate for the unevenness caused by the oblique angle of the opening, so that the blocking member 24 can fill the gap along the oblique direction of the opening. Similarly, the same is true for the blocking assembly 20 arranged obliquely downward. The elastic members 23 of the two blocking assemblies 20 respectively play the roles of buffering and adaptation, so as to ensure that the blocking member 24 can be elastically deformed according to the oblique degree and surface condition of the opening, thereby achieving good sealing.

[0027] Please refer to Figure 3 The blocking member 24 includes a blocking plate 240 mounted on the elastic member 23 and a convex sealing plug 241 mounted on the blocking plate 240. When the drive member 21 pushes the elastic member 23, the elastic force of the elastic member 23 acts on the blocking plate 240. Since the blocking plate 240 has a certain area and rigidity, it can uniformly distribute the elastic force of the elastic member 23 on the contact surface of the convex sealing plug 241. For example, if the elastic member 23 is a spring, the compression force of the spring is transmitted to the convex sealing plug 241 through the blocking plate 240, so that the sealing plug can be in contact with the opening on the side of the product with relatively uniform pressure. Positioning support: the blocking plate 240 also provides a stable mounting position for the convex sealing plug 241. It can ensure that the convex sealing plug 241 maintains the correct direction and position during contact with the opening of the product. The sealing plug can be firmly mounted on the blocking plate 240 and will not be displaced or inclined due to external force, thereby ensuring the stability of the sealing effect.

[0028] Please refer to Figure 2The blocking member 24 includes a blocking plate 240 mounted on the elastic member 23 and a concave sealing plug 242 mounted on the blocking plate 240. When the elastic member 23 is elastically deformed under the pressure of the driving member 21, the elastic force is transmitted to the blocking plate 240; the blocking plate 240 has a certain area and strength, which can uniformly disperse the elastic force to the mounting position of the concave sealing plug 242; the compression force of the elastic member 23 acts on the bottom of the concave sealing plug 242 through the blocking plate 240 in a more uniform manner, so that the sealing plug can contact the product side opening with stable pressure; the blocking plate 240 provides a stable mounting basis for the concave sealing plug 242; it can ensure that the concave sealing plug 242 maintains the correct position and direction during the entire blocking process; the concave sealing plug 242 can be accurately installed thereon, preventing displacement or rotation of the sealing plug when subjected to external force, and ensuring the effectiveness of the sealing operation.

[0029] The fixing assembly 10 includes a mounting bracket 11 and a mounting plate 12 arranged on the mounting bracket 11, and the driving member 21 is mounted on the mounting plate 12. Two arc-shaped grooves 13 are arranged on the two side walls of the mounting bracket 11, and the mounting plate 12 is mounted on the mounting bracket 11 through the two arc-shaped grooves 13. The mounting plate 12 is mounted by cooperating with the arc-shaped grooves 13 on the two side walls of the mounting bracket 11; during installation, the edge of the mounting plate 12 slides along the arc-shaped groove 13 until it reaches the predetermined installation position; this installation method enables the mounting plate 12 to be accurately positioned on the mounting bracket 11, and the angle and position of the mounting plate 12 can be adjusted within a certain range through the arc-shaped groove 13; the driving member 21 is mounted on the mounting plate 12, and the accurate installation of the mounting plate 12 ensures the accuracy of the initial position of the driving member 21; this enables the driving member 21 to align with the general direction of the product side opening in the initial state, providing a good starting condition for subsequent blocking operations; the arc-shaped design of the arc-shaped groove 13 allows the mounting plate 12 to rotate around a certain center point within a certain angle range; when the angle of the driving member 21 needs to be adjusted to adapt to the product side opening with different inclination angles, the mounting plate 12 is rotated within the arc-shaped groove 13 to achieve this; for example, if the product side opening is inclined upward, the mounting plate 12 is rotated upward within the arc-shaped groove 13 by a certain angle, and the driving member 21 mounted on the mounting plate 12 is also inclined upward, thereby better aligning with the opening for blocking; this angle adjustment method has high flexibility and accuracy; the angle of the driving member 21 can be accurately controlled by fine-tuning the position of the mounting plate 12 within the arc-shaped groove 13 according to the specific shape and opening position of the product; effectively improving the adaptability of the blocking device to different products, and effectively dealing with the diversity and complexity of products.

[0030] Please refer to Figure 3The support plate 22 is provided with a mounting channel 220 with one side open, and the driving member 21 includes a driving cylinder mounted on the fixed assembly 10 and a connecting part 25 mounted on the free end of the driving cylinder, and the connecting part 25 is fixedly mounted on both sides of the mounting channel 220. The design of the mounting channel 220 with one side open facilitates the installation of the connecting part 25 and can position the connecting part 25; when the piston of the driving cylinder moves, the connecting part 25 is pushed by the piston and transmits the force to the support plate 22; since the connecting part 25 is fixed on both sides of the mounting channel 220, the force can be evenly distributed on the support plate 22, so that the support plate 22 can move smoothly when subjected to the force, avoiding tilting or shaking due to uneven force.

[0031] The connecting part 25 includes a connecting column 250 mounted on the mounting channel 220 and fixing blocks 251 mounted on both ends of the connecting column 250, and the fixing blocks 251 are arranged on both sides of the support plate 22, and the free end of the driving cylinder is connected to the fixing block 251 close to the driving cylinder. The connecting column 250 is mounted in the mounting channel 220 of the support plate 22, and since the mounting channel 220 is a structure with one side open, the connecting column 250 can be easily inserted from the open side and positioned in the channel; this mounting method makes the connecting column 250 and the support plate 22 form a relatively stable connection structure, providing a basis for subsequent force transmission; the mounting channel 220 limits the movement direction of the connecting column 250 to a certain extent; the connecting column 250 mainly moves along the axial direction of the mounting channel 220, which can ensure that the force transmitted by the connecting column 250 is stable and will not deviate unnecessarily; the fixing blocks 251 provide additional support points at both ends of the connecting column 250, so that the connecting part 25 can be more firmly combined with the support plate 22; when the free end of the driving cylinder pushes the fixing block 251 close to it, the force is transmitted to the connecting column 250 through the fixing block 251, and then to the support plate 22 through the connecting column 250; the presence of the fixing block 251 makes the force more evenly distributed on both sides of the support plate 22, avoiding deformation or damage of the support plate 22 caused by force concentration at a certain point.

[0032] The driving member 21 further comprises a guide rod 26 mounted on the support plate 22, and the free end of the guide rod 26 penetrates the mounting plate 12. The guide rod 26 is mounted on the support plate 22, and the free end thereof penetrates the mounting plate 12, which precisely guides the movement of the driving member 21; when the driving cylinder pushes the support plate 22 to move, the guide rod 26 moves linearly along the penetrating hole or channel on the mounting plate 12; it ensures that the support plate 22 and the plugging assembly 20 can only move along the predetermined linear direction, and cannot deviate or tilt; the guide rod 26 limits the freedom of the support plate 22 in other directions; it ensures that the plugging assembly 20 stably moves towards the opening direction, so that the plugging member 24 can accurately align and contact the opening, thereby ensuring the accuracy and reliability of the plugging operation; during the movement of the driving member 21, the guide rod 26 can share part of the acting force; when the driving cylinder pushes the support plate 22, in addition to the main pushing force transmitted by the connecting part 25, the guide rod 26 will also be subjected to a certain pressure; these forces are transmitted to the mounting plate 12 through the guide rod 26, thereby forming a more reasonable force distribution in the structure of the entire device; the guide rod 26 helps to enhance the stability of the entire driving member 21 during movement.

[0033] Please refer to Figure 2 The side plugging device further comprises an air compression assembly 30 mounted on the fixed assembly 10 and an air pipe connected with the air compression assembly 30, and the free end of the air pipe is connected with the driving cylinder. The air compression assembly 30 is the power source of the entire driving system; the air pipe plays a bridge role of connecting the air compression assembly 30 and the driving cylinder; it transports the compressed air generated by the air compression assembly 30 to the driving cylinder; when the air compression assembly 30 generates compressed air, the air flows to the driving cylinder through the air pipe under the action of the pressure difference; according to the flow characteristics of the gas, as long as the pressure at the output end of the air compression assembly 30 is higher than that in the driving cylinder, the air will continuously enter the driving cylinder through the air pipe until the pressure balance or the air compression assembly 30 stops working.

[0034] The above only expresses the preferred technical solutions of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and the present application also intends to include these changes and modifications.
