[0036] Reference below Figure 1-Figure 5 The sealing machine interlocking mechanism and the vacuum sealing machine according to the embodiments of the utility model are described.

[0037] like Figure 1-Figure 5 As shown, the sealing machine interlocking mechanism is mainly used in vacuum sealing machines with an open-close structure, aiming to ensure that the vacuum sealing machine presses the bag opening of the sealed bag tightly to prevent the sealed bag from slipping during the vacuuming process and affecting the vacuuming effect.

[0038] Specifically, the sealer interlocking mechanism is applied to the upper cover 100 and the lower cover 200 of the vacuum sealer, and a vacuum sealing cavity is provided between the upper cover 100 and the lower cover 200. When the upper cover 100 and the lower cover 200 are buckled, the sealer interlocking mechanism prevents the upper cover 100 and the lower cover 200 from being separated.

[0039] The sealing machine interlocking mechanism includes a sliding latch portion 110 arranged on the upper cover 100, a locking portion 210 arranged on the surface of the lower cover 200, a latch push handle 120 for pushing the sliding latch portion 110, a safety lock 130 for preventing the sliding latch portion 110 from slipping, and a position sensing component 140 for sensing the locking state of the upper cover 100 and the lower cover 200.

[0040] The sliding latch part 110 is slidably connected in the upper cover 100, and the sliding latch part 110 is provided with a buckle block 111 and a toggle block 112. The lock part 210 is provided on the surface of the lower cover 200, and the lock part 210 and the buckle block 111 can be detachably buckled. Specifically, the upper cover 100 is provided with a slot corresponding to the active area of ​​the sliding latch part 110, and the lock part 210 can pass through the slot and buckle with the sliding latch part 110 in the upper cover 100.

[0041] The latch push handle 120 is rotatably connected to the interior of the upper cover 100 and is located above the sliding latch portion 110. The latch push handle 120 abuts against the toggle block 112. When the latch push handle 120 rotates, the latch push handle 120 pushes the toggle block 112 to make the buckle block 111 buckle with the lock portion 210. The latch push handle 120 is used to drive the sliding latch portion 110 to slide, thereby controlling the sliding latch portion 110 to separate or buckle with the lock portion 210.

[0042] The safety lock catch 130 is disposed above the sliding latch portion 110 . When the sliding latch portion 110 is separated from the lock catch portion 210 , the safety lock catch 130 falls into the sliding latch portion 110 to prevent the latch push handle 120 from driving the sliding latch portion 110 to slide.

[0043] The position sensing component 140 is disposed above the safety lock 130. When the sliding latch 110 is engaged with the lock 210, the lock 210 lifts up the safety lock 130, and the safety lock 130 abuts against the position sensing component 140. The position sensing component 140 uses a micro switch. When the safety lock 130 moves upward to touch the position sensing component 140, the position sensing component 140 generates an electrical signal that is fed back to the control component of the vacuum sealer. At this time, it means that the upper cover 100 and the lower cover 200 are fully engaged, allowing the vacuum sealer to perform vacuum sealing. In this embodiment, the safety lock 130 can be used to limit the movement of the sliding latch 110 and can also be used as a component to trigger the position sensing component 140.

[0044] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the upper cover 100 is provided with a rotatably connected cover opening handle 160, which is connected to the latch push handle 120, and the cover opening handle 160 drives the latch push handle 120 to rotate. Specifically, in order to facilitate the user to drive the latch push handle 120 to rotate, the cover opening handle 160 is provided on the upper cover 100, and the cover opening handle 160 can rotate at the position of the upper cover 100, and the cover opening handle 160 is fixedly connected to the latch push handle 120, so that the latch push handle 120 can be driven by pushing the cover opening handle 160. The cover opening handle 160 and the latch push handle 120 use the rotation connection as a fulcrum, and the effective force arm of the cover opening handle 160 is longer, and the latch push handle 120 can be driven by a small force, forming a labor-saving lever.

[0045] In a further embodiment, Figure 2 As shown, sealing machine interlocking mechanisms are respectively arranged on both sides of the upper cover 100, and the cover opening handle 160 is respectively connected to the latch push handles 120 on both sides through the rotating shaft 161, so as to simultaneously drive the sealing machine interlocking mechanisms on both sides to work.

[0046] Specifically, after the cover opening handle 160 is connected to the sealing machine interlocking mechanism on both sides of the upper cover 100 through the rotating shaft 161, the upper cover 100 and the lower cover 200 can be clamped at the same time, and the sealed bag is more evenly stressed. In addition, the cover opening handle 160 extends to the latch push handle 120 on both sides through the rotating shaft 161, and can adapt to vacuum sealers of different lengths and specifications. It only needs to adjust the length of the rotating shaft 161 according to actual conditions to adapt to the vacuum sealer of corresponding specifications.

[0047] In some embodiments of the present invention, Figure 3-Figure 5As shown, a latch return spring 113 is provided on one side of the sliding latch portion 110 away from the toggle block 112. When the latch push handle 120 pushes the sliding latch portion 110 to engage with the lock portion 210, the latch return spring 113 is in a compressed state. When the latch push handle 120 is separated from the toggle block 112, the latch return spring 113 pushes the sliding latch portion 110 to separate from the lock portion 210.

[0048] Specifically, one end of the latch return spring 113 abuts against the end of the sliding latch portion 110, and the other end abuts against the inner wall of the upper cover 100. The elastic potential energy of the latch return spring 113 is converted into mechanical potential energy to push the sliding latch portion 110 to reset when the upper cover 100 and the lower cover 200 are separated.

[0049] In some embodiments of the present invention, Figure 3-Figure 5 As shown, a fixing frame 150 is disposed in the upper cover 100, and a mounting groove 151 is disposed at one end of the fixing frame 150, and a limiting groove 152 is disposed in the middle. The toggle block 112 of the sliding latch portion 110 slides in the limiting groove 152, and the safety lock catch 130 is rotatably connected in the mounting groove 151.

[0050] Specifically, the fixing frame 150 is used as a component for limiting the sliding latch portion 110 and the safety lock catch 130 inside the upper cover 100. The fixing frame 150 is fixed inside the upper cover 100 by screws, and the toggle block 112 of the sliding latch portion 110 extends into the limiting groove 152, and the toggle block 112 can only slide back and forth in the limiting groove 152.

[0051] In a further embodiment, Figure 3-Figure 5 As shown, the sliding latch part 110 is provided with a positioning groove 114, and the buckle block 111 is provided in the positioning groove 114. When the upper cover 100 and the lower cover 200 are buckled, the lock part 210 is located in the positioning groove 114 and buckles with the buckle block 111. Specifically, when the upper cover 100 and the lower cover 200 are buckled, the lock part 210 is inserted into the positioning groove 114, and at this time, the sliding latch part 110 slides, so that the buckle block 111 can buckle with the lock part 210.

[0052] In a further embodiment, Figure 3-Figure 5 As shown, the lock part 210 is provided with a slot on one side close to the snap-fit ​​block 111, and the snap-fit ​​block 111 is a wedge-shaped structure. When the latch push handle 120 pushes the toggle block 112, the snap-fit ​​block 111 moves toward the slot of the lock part 210 to snap-fit. Specifically, the inclined surface of the toggle block 112 is close to the slotted side of the lock part 210. When the lock part 210 and the snap-fit ​​block 111 are connected, the inclined surface force of the snap-fit ​​block 111 can assist the snap-fit ​​block 111 to snap-fit ​​with the lock part 210, so that the upper cover 100 and the lower cover 200 are snap-fitted more tightly.

[0053] In a further embodiment, Figure 3-Figure 5 As shown, the safety lock catch 130 is located above the active area of ​​the positioning slot 114, and a torsion spring 131 is provided at the hinge between the safety lock catch 130 and the installation slot 151. When the sliding latch part 110 and the lock catch part 210 are separated, the safety lock catch 130 falls into the positioning slot 114 to limit the sliding of the sliding latch part 110. Specifically, when the upper cover 100 is separated from the lower cover 200, the safety lock catch 130 falls into the positioning slot 114 under the action of the torsion spring 131, and the sliding latch part 110 cannot slide at this time. If there is no safety lock catch 130, the sliding latch part 110 is in a buckled state and is buckled with the lock catch part 210, and the top of the lock catch part 210 will press against the sliding latch part 110. Excessive force can easily damage the lock catch part 210 or the sliding latch part 110. When the upper cover 100 and the lower cover 200 are buckled together, the locking portion 210 lifts up the safety lock 130 in the positioning groove 114, so that the safety lock 130 is separated from the positioning groove 114, and the locking portion 210 enters the positioning groove 114, so that a normal buckling operation can be achieved.

[0054] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the latch handle 120 is provided with a pushing block 121 and a limiting block 122, and a fitting groove 112-1 is provided on the side of the toggle block 112 close to the pushing block 121. When the toggle block 112 abuts against the fitting groove 112-1, the sliding latch portion 110 is engaged with the locking portion 210. A baffle 112-2 is provided on the side of the toggle block 112 close to the limiting block 122. When the limiting block 122 abuts against the baffle 112-2, the sliding latch portion 110 is completely separated from the locking portion 210.

[0055] Specifically, the included angle between the push block 121 and the limit block 122 is 70° to 90°. When the included angle is 90°, when the cover opening handle 160 is fully opened, the handle of the cover opening handle 160 is perpendicular to the surface of the upper cover 100. During the rotation of the latch push handle 120, the toggle block 112 is always located between the push block 121 and the limit block 122. When the sliding latch portion 110 and the lock portion 210 are fully engaged, the cover opening handle 160 is in contact with the surface of the upper cover 100, and the push block 121 is in contact with the engaging groove 112-1, preventing the cover opening handle 160 from loosening and causing the connection between the upper cover 100 and the lower cover 200 to loosen.
