Description

Technical Field

[0001] This application relates to the field of fastening technology, and in particular to a fastening mechanism and a vacuum sealing machine. Background Technology

[0002] Vacuum sealing machines typically require a mechanism to fasten the lid and the box body to hold the vacuum-sealed food bag in place, and then open it after the vacuum seal is complete. In related technologies, vacuum sealing machines often use a spring-loaded button mechanism: pressing the top of the lid engages the button, and pressing the spring buttons on both sides of the box body releases the button and opens the lid. This method is relatively laborious and requires both hands to operate, making it inconvenient. Utility Model Content

[0003] Therefore, it is necessary to provide a fastening mechanism and a vacuum sealing machine to address the problem of inconvenient operation of vacuum sealing machines.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, embodiments of this application provide a fastening mechanism applied to an electrical device having an opening and closing cover operation. The electrical device includes a main body and a cover, the cover being rotatably connected to the same side of the main body. The fastening mechanism includes:

[0006] A handle is provided on the opposite side of the cover and the main body, and one end is rotatably connected to the cover.

[0007] The latch has one end rotatably connected to the handle and the other end fastened to the main body;

[0008] The handle can controllably adjust the connection state between the latch and the main body, thereby adjusting the opening and closing angle between the cover and the main body.

[0009] In one embodiment of the first aspect, there are two of each of the handles and the latches, and each latch is connected to a corresponding handle.

[0010] The fastening mechanism further includes a connector, the two ends of which are respectively connected to the two handles.

[0011] In one embodiment of the first aspect, the main body is provided with a receiving groove on the side near the cover, and a fastening hole is provided on the inner side of the receiving groove;

[0012] The latch has a fastening part at the end away from the handle, and the fastening part engages with the fastening hole.

[0013] In one embodiment of the first aspect, the cover has a through hole, and a guide groove is provided on each of the two opposite sides of the through hole, the extension direction of the guide groove being parallel to the direction of gravity;

[0014] Each of the two opposite sides of the latch is provided with a guide pin, and each guide pin slides through a corresponding guide groove.

[0015] In one embodiment of the first aspect, the latch has a groove at one end near the handle, and the handle is provided with a corresponding pin, which slides through the groove.

[0016] In one embodiment of the first aspect, the groove is provided with straight segments and curved segments, and there is a smooth transition between the straight segments and the curved segments.

[0017] In one embodiment of the first aspect, the fastening mechanism further includes a stop ring, which is fixed to the cover body and has a limiting protrusion above it in the direction of gravity;

[0018] An adjustment block is provided on one side of the handle, and multiple recesses are provided on the side of the adjustment block near the stop ring. Each recess can sequentially engage with the limiting protrusion as the handle rotates.

[0019] In one embodiment of the first aspect, the fastening mechanism further includes a bracket, which is fixed to the cover body and has a shaft hole;

[0020] Both sides of the handle are provided with a rotating shaft, which passes through the shaft hole and rotates in cooperation with the bracket.

[0021] Secondly, this application also provides a vacuum sealing machine, including the fastening mechanism described in any of the above embodiments.

[0022] In one embodiment of the second aspect, the vacuum sealing machine further includes a protective housing that covers the end of the handle away from the cover.

[0023] Compared to related technologies, the advantages of this application are as follows: This application provides a fastening mechanism and a vacuum sealing machine, enabling rapid opening and closing of the vacuum sealing machine. The fastening mechanism includes a handle and a latch. The handle is located on the opposite side of the rotatable connection between the lid and the main body, with one end rotatably connected to the lid. One end of the latch is rotatably connected to the handle, and the other end is fastened to the main body. Thus, during the vacuum sealing process, the user only needs to move the handle to adjust the connection angle between the latch and the main body, thereby adjusting the opening angle between the lid and the main body. After placing the food storage bag between the lid and the main body, closing the lid achieves vacuum sealing of the food storage bag. The overall structure of this application is simple and easy to operate, allowing for vacuum sealing operations with only one hand, saving time and effort. Attached Figure Description

[0043] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and 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.

[0045] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0048] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0049] See Figure 1 and Figure 4As shown, an embodiment of this application provides a fastening mechanism 100, which can be used for opening and closing various electrical appliances. For ease of understanding, this embodiment uses the application of the fastening mechanism 100 to a vacuum sealing machine 1000 as an example. Of course, the application of the fastening mechanism 100 provided in this embodiment is not limited to vacuum sealing machines, but can also be applied to other equipment with opening and closing requirements, such as printers, printing presses, etc., which will not be listed here.

[0050] See also Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the vacuum sealing machine 1000 in the closed state. Figure 2 This is a schematic diagram of the vacuum sealing machine 1000 in the open state. The vacuum sealing machine 1000 includes a main body 300 and a cover 200. The cover 200 is rotatably connected to the main body 300 on the same side, so that the cover 200 and the main body 300 can be opened from opposite sides. Then, the opening of the plastic bag is placed on the open side of the cover 200 and the main body 300, and the cover is closed for vacuum sealing.

[0051] For example, the side where the main body 300 and the cover 200 are rotatably engaged is designated as the first side, and the side opposite to the first side is designated as the second side. The first side of the main body 300 and the cover 200 are rotatably connected by a structure such as a pin or hinge, while the other sides are in a separated state. Thus, the cover 200 can be opened through the second side to realize the closing and opening of the cover 200.

[0052] Continue reading Figure 3 As shown, the vacuum sealing machine 1000 further includes a fastening mechanism 100, which is installed on the second side of the cover 200 and the main body 300, so that the cover 200 can be closed to the main body 300 or opened from the main body 300 by applying a force to the second side of the cover 200.

[0053] Continue reading Figure 5 and Figure 6 As shown, specifically, the fastening mechanism 100 includes a handle 110 and a latch 120. The handle 110 is located on the opposite side of the cover 200 and the main body 300, with one end rotatably connected to the cover 200, so that force can be applied to the handle 110 to separate or close the cover 200 from the main body 300. One end of the latch 120 is rotatably connected to the handle 110, and the other end is engaged with the main body 300, so that the connection angle between the latch 120 and the main body 300 changes during the rotation of the handle 110, thereby selecting the corresponding opening angle between the cover 200 and the main body 300 during the opening of the cover 200.

[0054] For example, the two ends of the latch 120 are connected to the handle 110 and the main body 300, respectively. Since the handle 110 is mounted on the lid 200, the lid 200 and the main body 300 can be connected via the latch 120. As the angle of the latch 120 changes, the opening angle of the lid 200 and the main body 300 can be adjusted to meet the vacuum sealing requirements of various types of food storage bags. During operation, the handle 110 can rotate relative to the lid 200, causing the latch 120 to rotate as well. In the closed state, the latch 120 remains tilted or horizontal, engaging with the main body 300. The opening angle between the lid 200 and the main body 300 is small, and the user cannot directly open the lid 200 relative to the main body 300. During the opening process, the handle 110 drives the latch 120 to rotate, adjusting the latch 120 to a vertical or near-vertical position. This reduces the connection between the latch 120 and the main body 300, allowing the user to open the lid 200 by applying upward force with the handle 110. When the latch 120 is in a vertical position, it disengages from the main body 300, allowing the user to fully open the lid 200 to its maximum opening angle.

[0055] In some embodiments, there are two handles 110 and two latches 120, each latch 120 being connected to a corresponding handle 110. The fastening mechanism 100 also includes a connector 130, the two ends of which are connected to the two handles 110 respectively.

[0056] Specifically, two handles 110 are respectively located at opposite ends of the cover 200, and each is connected to a corresponding latch 120 to ensure a stable connection between the two ends of the cover 200 and the main body 300 and to ensure even force distribution. The connecting member 130 is a directional rod or tube, and a square groove structure is provided on the side of the two handles 110 that is close to each other. In this way, by placing the two ends of the connecting member 130 into the directional grooves of the two handles 110 respectively, only one handle 110 needs to be applied to achieve the rotation of both handles 110, enabling the user to operate with one hand, saving time and effort.

[0057] See Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the main body 300 has a receiving groove 310 on the side near the cover 200, and a fastening hole 320 is provided on the inner side of the receiving groove 310. The latch 120 has a fastening part 121 at the end away from the handle 110, and the fastening part 121 is engaged with the fastening hole 320.

[0058] Specifically, the receiving groove 310 has a rectangular structure to provide space for the latch 120 to move. The latching hole 320 is located at the end of the receiving groove 310 away from the first side of the main body 300. The latching part 121 has a hook-like structure design so that it can extend into the latching hole 320 and hook onto the wall of the main body 300. As the handle 110 is rotated upwards, the latch 120 rotates vertically, thereby reducing the portion of the latching part 121 within the latching hole 320, thus increasing the opening angle of the cover 200 relative to the main body 300. When the latch 120 is in a vertical position, it is completely disengaged from the main body 300, and the cover 200 can be fully opened relative to the main body 300.

[0059] In some embodiments, the latch 120 has a groove 122 at one end near the handle 110, and the handle 110 is provided with a corresponding pin 111, which slides through the groove 122.

[0060] Specifically, the slide groove 122 has an oblong groove structure, allowing the pin 111 to move within it. When the handle 110 is rotated, the pin 111 rotates accordingly, causing the latch 120 to rotate. Because of the slide groove 122, the pin 111 can move within it during rotation, increasing the range of motion of the latch 120 and further enhancing the opening angle adjustment range of the cover 200.

[0061] In some embodiments, the slide 122 is provided with straight segments and arc segments, and there is a smooth transition between the straight segments and the arc segments.

[0062] Specifically, when the latch 120 is in a vertical position, the arc segment is vertically above the straight segment. When the cover 200 is closed, the pin 111 is in the straight segment, and the latch 120 is tilted or nearly horizontal. During the opening process, as the handle 110 rotates, the pin 111 rotates and moves within the slide groove 122, eventually moving from the straight segment to the arc segment. The arc segment provides precise positioning for the pin 111, allowing the handle 110 to reach its maximum rotation position, disengaging the latch 120 from the main body 300, and enabling the cover 200 to open at its maximum angle.

[0063] Continue reading Figure 10 As shown, in some embodiments, the cover 200 has a through hole 220, and a guide groove 210 is provided on each of the two opposite sides of the through hole 220. The extension direction of the guide groove 210 is parallel to the direction of gravity. A guide pin 123 is provided on each of the two opposite sides of the latch 120, and each guide pin 123 slides through a corresponding guide groove 210.

[0064] Specifically, the guide groove 210 is set vertically, so that the lock 120 cannot move laterally during the rotation of the lock 120. Through the limiting cooperation between the guide pin 123 and the guide groove 210, the lock 120 moves up and down along the guide groove 210 as it follows the rotation of the handle 110. The pin 111 of the handle 110 moves in the slide groove 122 to prevent the lock 120 from deviating.

[0065] Continue reading Figure 11 and Figure 12 As shown, in some embodiments, the fastening mechanism 100 further includes a stop ring 140, which is fixed inside the cover 200 and has a limiting protrusion 141 above it in the direction of gravity. An adjusting block 112 is provided on one side of the handle 110, and a plurality of recesses 1121 are provided on the side of the adjusting block 112 near the stop ring 140. Each recess 1121 can sequentially engage with the limiting protrusion 141 as the handle 110 rotates.

[0066] Specifically, the limiting protrusion 141 contacts the bottom side of the adjusting block 112, and as the handle 110 rotates, the recesses 1121 of the adjusting block 112 sequentially engage with the limiting protrusion 141. This provides a tactile feedback during rotation through the elastic deformation of the stop ring 140, enhancing the user experience. Simultaneously, the multiple recesses 1121 limit the maximum rotation angle of the handle 110 during rotation, allowing the user to accurately control the opening and closing angle of the cover 200.

[0067] In some embodiments, the fastening mechanism 100 further includes a bracket 150, which is fixed inside the cover 200 and has a shaft hole. A rotating shaft 113 is provided on both sides of the handle 110, and the rotating shaft 113 passes through the shaft hole and rotatably engages with the bracket 150.

[0068] Specifically, each handle 110 has a bracket 150 on both sides, the bracket 150 is fixed inside the cover 200, and the top is provided with a shaft hole. Each of the two opposite sides of the handle 110 is provided with a rotating shaft 113, and through the cooperation of the rotating shaft 113 with the shaft hole, the handle 110 can rotate relative to the bracket 150, thereby improving the movement stability of the handle 110.

[0069] In some embodiments, the vacuum sealing machine 1000 further includes a protective housing 400, which covers the end of the handle 110 away from the cover 200.

[0070] Specifically, the protective housing 400 can simultaneously cover two opposing handles 110, so that during the opening and closing of the cover 200, the user only needs to rotate the protective housing 400 to rotate the handles 110, providing the user with more points of force application, and can simultaneously drive both handles 110 to rotate, allowing the user to open and close the cover 200 with only one hand. At the same time, the protective housing 400 can be decorated with patterns or designs corresponding to the cover 200 and the main body 300 to enhance the overall aesthetics of the vacuum sealing machine 1000.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
