Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0031] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] The buckles of existing vacuum sealing machines are usually arranged in multiple groups. During use, uneven force may occur due to the asynchronous opening of the buckles. Stress concentration may frequently occur in some areas of the snap-fitting parts, making the fasteners easily damaged due to mechanical fatigue, which may cause the buckles to fail to close properly and affect the sealing quality.

[0033] Reference Figure 1-3 As shown, a vacuum sealer with a buckle comprises:

[0034] A main body 1, and a cover 2 rotatably mounted on the main body 1;

[0035] A buckle assembly 3 is provided between the main body 1 and the cover 2, and the buckle assembly 3 includes:

[0036] A group of fasteners 31 are symmetrically arranged below the cover 2, and adjacent sides of two fasteners 31 are recessed inward to form a fastening groove 311;

[0037] A group of clamps 32 symmetrically arranged on the main body 1, wherein the middle parts of the two clamps 32 on opposite sides protrude outward to form a clamping portion 321, wherein the clamping portion 321 matches the buckle groove 311, and the clamps 32 are slidably installed in the main body 1;

[0038] and a driving member for driving the clamping member 32 to move laterally;

[0039] The cover 2 is turned over and pressed down to buckle onto the main body 1 , the clamping portion 321 is inserted into the buckling groove 311 , and the clamping member 32 is controlled by the driving member to slide sideways, so that the clamping portion 321 is synchronously disengaged from the buckling groove 311 .

[0040] The drive member synchronously drives the symmetrically arranged clamping member 32 and fastener 31 to cooperate, thereby solving the problem of asynchronous force in the clamping and opening process of the existing vacuum sealer. Specifically, the fastener 31 is arranged below the cover 2 and forms a fastening groove 311, while the clamping member 32 is arranged on the main body 1 and forms a clamping portion 321, and the clamping portion 321 is inserted into the fastening groove 311 to achieve fastening. The clamping member 32 is controlled by the drive member to slide laterally to ensure that the clamping portion 321 and the fastening groove 311 can be disengaged synchronously, avoiding the problem of stress concentration in some areas, thereby effectively preventing the fastener 31 from being damaged due to mechanical fatigue and improving the sealing quality.

[0041] The symmetrical buckle structure and synchronous disengagement mechanism ensure that the buckle is evenly stressed during opening and closing, reducing the risk of mechanical fatigue damage. At the same time, the precise control of the drive makes the entire sealing process smoother, improves the stability and durability of the equipment, and achieves a high-quality and reliable vacuum sealing effect.

[0042] In order to provide power for the lateral return of the clamping member 32 , a spring tube 33 is provided on the adjacent side of the two clamping members 32 . A spring 34 is inserted into the spring tube 33 . The end of the spring 34 away from the clamping member 32 abuts against the inside of the main body 1 .

[0043] The spring 34 will be elastically deformed after being stressed, and the spring 34 can automatically reset after the card 32 slides. When the driving member stops working, the elastic force of the spring 34 can push the card 32 back to its original position, ensuring that the card 32 can accurately return to its initial position.

[0044] At the same time, during the closing or opening process of the cover 2, impact forces may be generated due to human operation or mechanical movement. The spring 34 can absorb and buffer these impact forces, reduce damage to the clamp 32 and other components, and improve the durability of the equipment.

[0045] During the sealing process, the spring 34 can continuously provide an outward pushing force to ensure that the clamping portion 321 is tightly embedded in the clamping groove 311, thereby improving the tightness and reliability of the sealing. The spring 34 provides a constant pressure, and the entire buckling operation process becomes more stable and smooth, avoiding the displacement or damage of the clamping member 32 due to uneven force.

[0046] The spring barrel 33 is integrally formed with the clamp 32. The integrally formed design makes the spring barrel 33 and the clamp 32 a whole, avoiding the risk of loosening or breaking of the connection parts between the components, and improving the structural strength and stability of the entire buckle assembly 3.

[0047] The integrated design eliminates the joint interface between the spring tube 33 and the clamp 32, reduces possible failure points, thereby improving the reliability and durability of the product and reducing the maintenance requirements caused by loosening or falling off during use.

[0048] In order to achieve the bottom support of the clamp 32 and the stability of the left and right lateral movement, the top of the clamp 32 is open, and support bars 322 are provided on the left and right sides of the clamp 32;

[0049] The main body 1 is provided with a guide platform 35 below the clamp 32 , and the support bar 322 is slidably mounted below the guide platform 35 .

[0050] By arranging support bars 322 on the left and right sides of the clamp 32, and slidingly installing the lower part of the support bars 322 on the guide platform 35, the guide platform 35 can provide a stable and reliable support surface for the clamp 32. It ensures that the clamp 32 will not tilt or shake due to uneven force during operation, thereby improving the stability of the clamp 32.

[0051] The top of the card 32 is in an open state, and the support bar 322 and the guide platform 35 slide together, so that the card 32 can move freely and smoothly left and right within a certain range. The sliding guide design between the guide platform 35 and the support bar 322 can effectively reduce friction resistance, thereby achieving smooth left and right movement of the card 32.

[0052] At the same time, the open state of the top can ensure that the fastener 31 and the clamp 32 are better matched.

[0053] The guide platform 35 is fixedly connected to the main body 1 by bolts, so that when the guide platform 35 needs to be repaired or replaced, it can be completed by simply removing the bolts without significantly disassembling the overall structure, which reduces the difficulty and time of repair and improves the maintenance efficiency.

[0054] The guide platform 35 is fixed to the main body 1 by bolts, and the whole structure is more compact and integrated, which can not only improve the overall stability, but also reduce vibration and noise, and improve the running stability and service life of the equipment.

[0055] A first guide portion 312 is disposed above the clamping portion 321 . The first guide portion 312 is inclined from the top toward obliquely downward.

[0056] A second guide portion 323 is disposed below the buckle slot 311 . The second guide portion 323 is inclined from the bottom toward the upper side. The second guide portion 323 matches the first guide portion 312 .

[0057] The first guide portion 312 and the second guide portion 323 are respectively designed to be inclined downward from the top and upward from the bottom, and the two match each other. This design makes it easier to position and align the clamping portion 321 and the buckle groove 311 when docking, reducing the difficulty of initial docking, thereby achieving fast and accurate installation.

[0058] The matching inclined guide portion plays an automatic correction role during the joining process. Even if there is a certain deviation during the operation, the inclined guiding effect can gradually guide the card 32 to the correct position, thereby reducing the error caused by manual docking and improving the installation accuracy.

[0059] The inclined guide structure makes the contact area larger during the clamping process, avoiding the high friction and wear caused by single-point contact. At the same time, this inclined contact design can provide a smooth transition during the clamping process, reduce mutual friction, and extend the service life of the component.

[0060] The driving member includes a pressing block 36 disposed on the side of the support bar 322 facing outward, and the pressing block 36 connects two support bars 322 of the same group. An arc groove 361 is disposed in the middle of the outer side surface of the pressing block 36.

[0061] Pressing the pressing block 36 with both hands simultaneously can ensure that the applied pressure is evenly distributed on the two support bars 322 in the same group, avoiding tilting or jamming of the support bar 322 due to uneven force during single-handed operation, thereby improving the stability and reliability of the operation.

[0062] The design of the arc groove 361 allows the hand to fit the pressing block 36 naturally, providing a better grip and control feeling. This allows the required pressing force to be applied more accurately, ensuring more precise positioning and movement during operation.

[0063] By pressing with both hands, the operator's strength is dispersed to both hands instead of concentrating on one hand, reducing fatigue and excessive force on one hand, thereby improving the comfort and duration of operation. For situations where long-term repeated pressing is required during operation.

[0064] Example 2

[0065] Reference Figure 4-5This embodiment is basically the same as embodiment 1, except that the driving member includes an air pipe head 37 arranged above the middle of the guide platform 35, an air pump 38 arranged inside the main body 1, a connecting pipe 39 connecting the air pipe head 37 and the air pump 38, and a switch module 310 for controlling the opening and closing of the air pump 38. The output port of the air pipe head 37 abuts against the inner side of the clamp 32. Through the cooperation of the switch module 310 with the air pump 38, the air pipe head 37 and the connecting pipe 39, the airflow drives the clamp 32 to slide laterally, and the clamping portion 321 synchronously disengages from the snap-on groove 311.

[0066] The air pump 38, the air pipe head 37 and the connecting pipe 39 are used to control the airflow to drive the clamp 32 to slide sideways, thereby realizing automatic operation. The operation of the air pump 38 can be precisely controlled by the switch module 310, so that the sliding speed and strength of the clamp 32 can be adjusted according to specific needs, thereby ensuring the stability and safety of the clamping part 321 when it is separated from the buckle groove 311, and avoiding damage caused by improper manual operation.

[0067] Automated equipment can significantly reduce errors in human operation, ensure the consistency and accuracy of each operation, and improve product quality and reliability. The response speed of the pneumatic system is usually very fast, and it can achieve the drive and control of the card 32 in a very short time, which improves the operation efficiency and is suitable for scenes that require quick response. Compared with mechanical drive, pneumatic drive has better buffering effect, which can reduce vibration and impact during operation, protect the card 32 and other components from damage, and extend the service life of the equipment.

[0068] Setting up both mechanical drive and air pump 38 drive can maximize the advantages of both and achieve operational flexibility and reliability. Mechanical drive provides the precision and stability of manual operation, which is suitable for delicate and manual control scenarios, while air pump 38 drive significantly improves operational efficiency and reduces physical exertion through automation and rapid response. The combination of the two drive modes not only diversifies the opening methods and can cope with different working conditions and needs, but also improves the redundancy and reliability of the system, ensuring that when one drive mode fails, the operation can still be completed by another method, thereby improving the stability and safety of the overall system.
