DETAILED DESCRIPTION

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The utility model aims to provide an opening and closing mechanism 100 of a trash bin 1000 and a trash bin 1000, which can realize the opening and closing of a door body 300 and the unlocking and locking of the door body 300 by a linear drive member 20, thereby simplifying the structure, improving reliability and reducing costs.

[0037] Reference Figures 1 to 7 According to the opening and closing mechanism 100 in the embodiment of the utility model, the opening and closing mechanism 100 can be used for a trash bin 1000, wherein the trash bin 1000 includes a box body 200 and a door body 300 for opening and closing the box body 200, the door body 300 has a first end 301 and a second end 302 opposite to each other, and the first end 301 of the door body 300 is rotatably connected to the box body 200; in detail, the door body 300 and the box body 200 can be respectively connected to the opening and closing mechanism 100, and the opening and closing of the door body 300, as well as the locking and unlocking of the door body 300 can be realized through the opening and closing mechanism 100, and the opening and closing mechanism 100 has a simple structure, high reliability, and can reduce costs.

[0038] In more detail, the opening and closing mechanism 100 includes a locking member 10, a linear driving member 20 and a limiting member.

[0039] The locking member 10 is connected to the housing 200, and has a locking position for locking the door body 300 and an unlocking position for unlocking the door body 300; the first end of the linear drive member 20 is connected to the locking member 10, and the second end is connected to the door body 300; in the process of unlocking and opening the door body 300: the linear drive member 20 first drives the locking member 10 to move in a first direction, so that the locking member 10 moves from the locking position to the unlocking position, and the limiting member is connected to the housing 200, and when the locking member 10 is in the unlocking position, the limiting member is used to limit the linear drive member 20 from driving the locking member 10 in the first direction, so that the linear drive member 20 moves to the second direction The door body 300 is driven to open in two directions, the second direction being the opposite direction to the first direction; in the process of closing and locking the door body 300, the linear drive member 20 first drives the door body 300 to close in the first direction, and then the second end of the linear drive member 20 remains stationary relative to the box body 200, and the first end of the linear drive member 20 drives the locking member 10 to move in the second direction, so that the locking member 10 moves from the unlocking position to the locking position, thereby locking the door body; with this arrangement, the opening and closing mechanism 100 can realize the opening and closing of the door body 300, as well as the unlocking and locking of the door body 300, with a simple structure, high reliability, and low cost.

[0040] In some specific examples, the linear drive member 20 may include a pneumatic cylinder, a hydraulic cylinder, an electric push rod, etc.

[0041] For ease of description, refer to Figures 1 to 3 The position in the description:

[0042] Among them, an opening is provided on the rear side of the box body 200, and the first end 301 of the door body 300 is hinged to the upper side of the opening and can be rotated up and down to open and close the opening; the limiting member is provided with a slide groove 210, and the slide groove 210 can extend in the up and down direction.

[0043] The working process of the opening and closing mechanism 100 is as follows: when the door body 300 of the trash bin 1000 is opened, the linear driving member 20 in the opening and closing mechanism 100 can extend to drive the locking member 10 to move from the locked position to the unlocked position, that is, the locking member 10 moves downward, from Figure 1 Move the displayed position to Figure 2The position shown in the figure, thereby unlocking the second end 302 of the door body 300. At this time, the locking member 10 is in the unlocked position and abuts against the slide groove 210 of the box body 200 under the action of gravity, that is, the slide groove 210 of the limiting member can limit the locking member 10, so that the locking member 10 cannot continue to move downward. At this time, the linear drive member 20 can reversely drive the door body 300 to rotate relative to the box body 200, thereby opening the box body 200; when the door body 300 of the trash bin 1000 is closed, the linear drive member 20 can retract, and the door body 300 rotates relative to the box body 200 under the action of gravity, thereby closing the box body 200, and the locking member 10 is also maintained in the unlocked position under the action of gravity, and then the linear drive member 20 can overcome the action of gravity to drive the locking member 10 to move from the unlocked position to the locked position, thereby locking the second end 302 of the door body 300.

[0044] Of course, in other embodiments of the present invention, an opening is provided at the top of the box body 200, and the first end 301 of the door body 300 is hinged to the front side of the opening, and can be rotated forward and backward to open and close the opening; the limiting member is provided with a slide groove 210, and the slide groove 210 can extend along the front and rear directions.

[0045] The working process of the opening and closing mechanism 100 is as follows:

[0046] When the door 300 of the trash bin 1000 is opened, the driving member in the opening and closing mechanism 100 can be extended to drive the locking member 10 to move from the locked position to the unlocked position, that is, the locking member 10 moves backward, thereby unlocking the second end 302 of the door 300. At this time, the locking member 10 is in the unlocked position and abuts against the slide groove 210 of the box body 200, that is, the slide groove 210 of the limiting member can limit the locking member 10, so that the locking member 10 cannot continue to move backward. At this time, the linear driving member 20 can reversely drive the door body 300 to rotate relative to the box body 200. When the door 300 of the trash bin 1000 is closed, the linear drive member 20 can be retracted, and the door 300 rotates relative to the box body 200 under the action of gravity. At this time, the door body 300 can apply pressure to the linear drive member 20, so that the locking member 10 connected to the linear drive member 20 can be maintained in the unlocked position, thereby closing the box body 200. Then the linear drive member 20 continues to retract to drive the locking member 10 to move from the unlocked position to the locked position, thereby locking the second end 302 of the door body 300.

[0047] Therefore, without changing the design principle of the utility model, the technical solution of the utility model is realized by changing the orientation, which still falls within the protection scope of the utility model. Therefore, according to the opening and closing mechanism 100 in the embodiment of the utility model, the linear drive member 20 can realize the opening and closing of the door body 300, and the locking member 10 can realize the unlocking and locking of the door body 300, thereby simplifying the structure, improving reliability and reducing costs.

[0048] Further, see Figures 1 to 3 In some embodiments of the utility model, the locking member 10 is closer to the first end 301 in the locking position than in the unlocking position. Such a configuration can simplify the driving process of the linear drive member 20. The door body 300 can be unlocked and opened, and closed and locked through the unidirectional drive of the linear drive member 20.

[0049] In detail, the two ends of the linear drive member 20 can be respectively connected to the locking member 10 and the door body 300; when the linear drive member 20 drives the door body 300 to open the box body 200, the two ends of the linear drive member 20 can move in the direction away from each other. Since the damping of the door body 300 is relatively large, one end of the linear drive member 20 that is connected to the door body 300 can remain unchanged, while the other end of the linear drive member 20 can drive the locking member 10 to move from the locked position to the unlocked position, so that the locking member 10 can unlock the second end 302 of the door body 300. At this time, the locking member 10 can be located in the unlocked position, and the linear drive member 20 can no longer continue to drive the locking member 10 to move, but instead drives the door body 300 to rotate relative to the box body 200, thereby opening the box body 200.

[0050] On the contrary, when the door body 300 is closed, the two ends of the linear drive member 20 can move towards each other, and the relative position of the other end of the linear drive member 20 and the box body 200 remains unchanged. One end of the linear drive member 20 can drive the door body 300 to rotate relative to the box body 200 to close the box body 200; then, the linear drive member 20 can no longer drive the door body 300 to move, and instead drives the locking member 10 to move from the unlocking position to the locking position, so that the locking member 10 locks the second end 302 of the door body 300.

[0051] According to the above, when the linear drive member 20 is working, the two ends of the linear drive member 20 move in directions away from each other to complete the unlocking of the second end 302 of the door body 300 and the opening of the door body 300; the two ends of the linear drive member 20 move in directions approaching each other to complete the closing of the door body 300 and the locking of the second end 302 of the door body 300; that is, the linear drive member 20 can achieve the unlocking and opening of the door body 300 by extending, and can achieve the closing and locking of the door body 300 by retracting, and the locking and driving process are simple and reliable.

[0052] Reference Figures 1 to 3 In some embodiments of the utility model, a fixing member 310 is provided on the door body 300, and the fixing member 310 is located at the second end 302. The locking member 10 includes a locking hook 101. When in the locked position, the locking hook 101 hooks the fixing member 310, and when in the unlocked position, the locking hook 101 escapes from the fixing member 310, so that the door body 300 can be locked and unlocked.

[0053] Specifically, when the locking member 10 is in the locked position, the lock hook 101 of the locking member 10 can hook the fixing member 310 on the door body 300, thereby locking the second end 302 of the door body 300; when unlocking, the linear drive member 20 can drive the locking member 10 to move from the locked position to the unlocked position, so that the lock hook 101 of the locking member 10 can escape from the fixing member 310, and at this time the second end 302 of the door body 300 is unlocked; then the linear drive member 20 can drive the door body 300 to open, or it can drive the door body 300 to close after the door body 300 is opened, at this time the locking member 10 is still in the unlocked position, and the linear drive member 20 can drive the locking member 10 to move from the unlocked position to the locked position, so that the lock hook 101 of the locking member 10 can hook the fixing member 310 of the door body 300, thereby locking the second end 302 of the door body 300.

[0054] Reference Figures 1 to 3 In some embodiments of the utility model, the lock hook 101 has a connecting end and a free end which are transmission-connected to the linear drive member 20, and the free end extends in a direction close to the first end 301 and gradually moves away from the box body 200, so as to construct a guide structure 102 on the side of the free end facing the box body 200; in this way, it is convenient for the lock hook 101 to lock and unlock the door body 300, and facilitate the opening and closing of the door body 300.

[0055] Specifically, the lock hook 101 can be U-shaped, and the U-shaped lock hook 101 can be open toward the first end 301 of the door body 300, wherein the lock hook 101 has a connecting end and a free end, the connecting end is closer to the box body 200 than the free end, and the connecting end can be connected to the linear drive member 20 for transmission; when the linear drive member 20 drives the locking member 10 to move from the unlocking position to the locking position, the guide structure 102 at the free end of the lock hook 101 can guide the lock hook 101 to hook the fixing member 310, and the guide structure 102 is located on the side of the free end facing the box body 200, which can prevent the second end of the door body 300 from being locked. 302 moves in a direction away from the box body 200 and rotates around the first end 301 of the door body 300 to open the box body 200, thereby locking the second end 302 of the door body 300; when the linear drive member 20 drives the locking member 10 to move from the locked position to the unlocked position, the guide structure 102 at the free end of the lock hook 101 can guide the lock hook 101 to escape from the fixing member 310, thereby unlocking the second end 302 of the door body 300; in short, when the lock hook 101 hooks and escapes from the fixing member 310, the guide structure 102 can guide the lock hook 101 to cooperate with the fixing member 310, thereby improving the smoothness of the movement of the structural member.

[0056] Reference Figures 1 to 3In some embodiments of the utility model, the aforementioned limiting member may have a slide groove 210, which extends in the direction of the first end 301 and has one end close to the first end 301 and the other end away from the first end 301, and the locking member 10 can be slidably arranged in the slide groove 210; when in the locked position, the locking member 10 is located at one end of the slide groove 210, and when in the unlocked position, the locking member 10 is located at the other end of the slide groove 210; in this way, the locking member 10 can be guided and limited by the slide groove 210 to ensure the normal operation of the opening and closing mechanism 100.

[0057] In detail, when the linear driving member 20 drives the locking member 10, the locking member 10 can be slidably set in the slide groove 210. The slide groove 210 can provide guidance for the movement of the locking member 10, so that the locking member 10 can move stably between the locking position and the unlocking position, thereby ensuring the normal operation of the opening and closing mechanism 100.

[0058] In addition, under the driving action of the linear drive member 20, when the locking member 10 moves to the locking position, the locking member 10 can be located at one end of the slide groove 210, at which time the locking member 10 can lock the second end 302 of the door body 300, and one end of the slide groove 210 can limit the locking member 10; similarly, when the locking member 10 moves to the unlocking position, the locking member 10 can be located at the other end of the slide groove 210, at which time the locking member 10 can unlock the second end 302 of the door body 300, and the other end of the slide groove 210 can limit the locking member 10; in other words, the slide groove 210 can limit the locking member 10 within a certain range to prevent the locking member 10 from deviating from the predetermined moving range and affecting the normal operation of the opening and closing mechanism 100.

[0059] Reference Figures 1 to 3 In some embodiments of the utility model, the opening and closing mechanism 100 also includes a connecting rod transmission assembly 30, which is respectively connected to the door body 300 and the box body 200, and has a folded position and an unfolded position. The linear drive member 20 is connected to the connecting rod transmission assembly 30; wherein, the door body 300 is closed in the folded position, and is opened in the unfolded position; therefore, the opening and closing efficiency of the door body 300 can be improved by the connecting rod transmission assembly 30.

[0060] The connecting rod transmission assembly 30 may include a plurality of connecting rods, and the plurality of connecting rods may form a connecting rod mechanism. The connecting rod mechanism may be switched between folding and unfolding under the drive of the linear drive member 20 .

[0061] Specifically, when the opening and closing mechanism 100 is working, the linear drive member 20 can drive the locking member 10 to move in a direction away from the first end 301 to move to the unlocking position, thereby unlocking the second end 302 of the door body 300. At this time, the locking member 10 is located at the other end of the slide groove 210. Through the limitation of the slide groove 210, the locking member 10 cannot continue to move in a direction away from the first end 301, and thus can reversely drive the door body 300 to rotate around its own first end 301 to open the door body 300. During this process, the linear drive member 20 and the door body 300 are transmitted through the connecting rod transmission assembly 30. The linear drive member 20 can drive the connecting rod transmission assembly 30 to switch from the folded position to the unfolded position, so that the door body 300 can be rotatably opened The box body 200; wherein, the connecting rod transmission assembly 30 can increase the driving stroke of the linear drive member 20 and improve the opening and closing efficiency of the door body 300.

[0062] Furthermore, the connecting rod transmission assembly 30, the door body 300 and the box body 200 can form a connecting rod mechanism, through which the stability of the opening and closing of the door body 300 can be improved, and the door body 300 can be opened and closed within a predetermined range; in detail, referring to the figures, in some embodiments of the utility model, the connecting rod transmission assembly 30 includes a first connecting rod 31 and a second connecting rod 32, one end of the first connecting rod 31 is hinged to the box body 200, and the other end is hinged to one end of the second connecting rod 32, and the other end of the second connecting rod 32 is hinged to the door body 300; in other words, the door body 300, the box body 200, the first connecting rod 31 and the second connecting rod 32 form a four-bar linkage, wherein , the linear drive member 20 drives the first connecting rod 31 to rotate relative to the box body 200; when the opening and closing mechanism 100 is working, the linear drive member 20 can drive the first connecting rod 31 to rotate relative to the box body 200, so that the first connecting rod 31 and the second connecting rod 32 are switched from the folded position to the unfolded position, thereby driving the door body 300 to rotate relative to the box body 200 to open the box body 200; on the contrary, the linear drive member 20 can drive the first connecting rod 31 to rotate relative to the box body 200, so that the first connecting rod 31 and the second connecting rod 32 are switched from the unfolded position to the folded position, thereby driving the door body 300 to rotate relative to the box body 200 to close the box body 200.

[0063] Reference Figures 1 to 7 In other embodiments of the present invention, the linear drive member 20 is a linear drive mechanism, and the driving route of the linear drive mechanism can be a straight line, so that the linear drive member 20 is simple and reliable, ensuring the normal operation of the opening and closing mechanism 100. Optionally, the linear drive mechanism can be a cylinder, a hydraulic cylinder, an electric push rod, etc. Preferably, the linear drive mechanism can be an electric push rod. Compared with using a cylinder and a hydraulic cylinder as the linear drive member 20, the electric push rod does not need to be provided with a corresponding cylinder system or hydraulic system.

[0064] Reference Figures 1 to 6According to the trash bin 1000 in the embodiment of the utility model, the trash bin 1000 includes a box body 200, a door body 300 and the opening and closing mechanism 100 in the above embodiment.

[0065] Among them, the door body 300 has a first end 301 and a second end 302. The first end 301 is hinged to the box body 200 and is used to open and close the box body 200. The opening and closing mechanism 100 connects the box body 200 and the door body 300 respectively. By applying the aforementioned opening and closing mechanism 100, the opening and closing of the door body 300, as well as the locking and unlocking of the door body 300 can be realized, thereby improving the reliability of the trash can 1000.

[0066] It should be supplemented that the locking member 10 can be maintained in the unlocked position in a variety of ways to facilitate the opening and closing of the door body 300; for example, it can be achieved by arranging an elastic member in the slide groove 210; for example, it can be achieved by arranging the locking member 10 in an orientation, that is, the locking member 10 is located below the linear drive member 20; but this is not a limitation on the scope of protection of the present utility model.

[0067] For example, the linear drive member 20 can be an electric push rod, one end of which is hinged to the first connecting rod 31, and the other end of the electric push rod is hinged to the locking member 10, and the locking member 10 can be slidably disposed in the slide groove 210, and slide along the slide groove 210 to move away from or close to the first end 301 of the door body 300; when the opening and closing mechanism 100 drives the door body 300 to open, the two ends of the linear drive member 20 move in a direction away from each other, and because the damping of the door body 300 is relatively large, the damping between the slide groove 210 and the locking member 10 is relatively small, and thus the linear drive member 20 can first drive the locking member 10 along the slide groove 210 is away from the first end 301 of the door body 300, and unlocks the second end 302 of the door body 300 when in the unlocked position. At this time, the locking member 10 is located at the other end of the slide groove 210, and the other end of the slide groove 210 limits the locking member 10, so that the locking member 10 cannot continue to move away from the first end 301 of the door body 300, so the linear drive member 20 can drive the first connecting rod 31 in a direction to make the first connecting rod 31 rotate relative to the box body 200, so that the first connecting rod 31 and the second connecting rod 32 can switch from the folded position to the unfolded position, thereby driving the door body 300 to rotate relative to the box body 200 to open the box body 200.

[0068] On the contrary, the opening and closing mechanism 100 may include an elastic member, which may be connected to the box body 200 and the locking member 10 respectively, and has an elastic force to drive the locking member 10 to move from the locked position to the unlocked position; when the opening and closing mechanism 100 drives the door body 300 to close, since the damping of the door body 300 is less than the elastic force of the elastic member, the linear drive member 20 can drive the first connecting rod 31 to rotate the first connecting rod 31 relative to the box body 200, so that the first connecting rod 31 and the second connecting rod 32 can switch from the unfolded position to the folded position, thereby driving the door body 300 to rotate relative to the box body 200 to close the box body 200. At this time, one end of the linear drive member 20 can maintain a relative position unchanged with the box body 200, and the other end of the linear drive member 20 can overcome the elastic force of the elastic member to drive the locking member 10 to move from the unlocked position to the locked position to lock the second end 302 of the door body 300.

[0069] Furthermore, the locking member 10 may include a locking hook 101, which may be a U-shaped structure and have a connecting end and a free end. The connecting end of the locking hook 101 may be hinged to the lower end of the linear drive member 20, and the free end of the locking hook 101 may extend in a direction close to the first end 301 and gradually away from the box body 200, so that the free end is configured to form a guide structure 102 toward one side of the box body 200, so that when the locking member 10 moves between the locked position and the unlocked position, the locking hook 101 can hook and disengage the fixing member 310, thereby realizing the locking and unlocking of the second end 302 of the door body 300.

[0070] For example, refer to Figures 1 to 6 In some embodiments of the utility model, the box body 200 extends in the front-to-back direction and has an opening on the rear side, the door body 300 extends in the up-down direction, the upper end of the door body 300 is hinged to the box body 200, and is used to open and close the opening, the locking member 10 is movably arranged on the box body 200 in the up-down direction, the second end 302 is locked when the locking member 10 moves up, and the second end 302 is unlocked when the locking member 10 moves down, the linear drive member 20 extends in the up-down direction, the upper end of the linear drive member 20 is transmission connected to the door body 300, and the lower end of the linear drive member 20 is transmission connected to the locking member 10; such a configuration can realize the opening and closing of the door body 300 by the opening and closing mechanism 100.

[0071] In which, in combination with the aforementioned embodiment, the slide groove 210 extends in the up and down directions, the locking member 10 moves upward to move to one end of the slide groove 210, and the locking member 10 moves downward to move to the other end of the slide groove 210; the upper end of the door body 300 is the first end 301 in the aforementioned embodiment, and the lower end of the door body 300 is the second end 302 in the aforementioned embodiment.

[0072] Specifically, when the opening and closing mechanism 100 drives the door body 300 to open, due to the gravity of the door body 300, one end of the linear drive member 20 indirectly connected to the door body 300 can remain in a relative position with the box body 200. When the linear drive member 20 is driven, the lower end of the linear drive member 20 can move downward to drive the locking member 10 to move from the locked position to the unlocked position, that is, move downward, thereby unlocking the second end 302 of the door body 300. At this time, the locking member 10 can be located at the other end of the slide groove 210 and cannot continue to move downward due to the limiting effect of the slide groove 210. Subsequently, the linear drive member 20 can overcome the gravity of the door body 300 to drive the first connecting rod 31 to rotate relative to the box body 200, so that the first connecting rod 31 and the second connecting rod 32 switch from the folded position to the unfolded position, thereby driving the door body 300 to rotate relative to the box body 200 to open the box body 200.

[0073] On the contrary, when the opening and closing mechanism 100 drives the door body 300 to close, under the action of gravity, the locking member 10 remains in the unlocked position, one end of the linear drive member 20 moves toward the other end of the linear drive member 20, and the door body 300 indirectly connected to one end of the linear drive member 20 can also rotate relative to the box body 200 to close the box body 200; then, since the box body 200 is closed, the relative position of one end of the linear drive member 20 and the box body 200 remains unchanged, and the other end of the linear drive member 20 can move toward one end of the linear drive member 20 to drive the locking member 10 to move from the unlocked position to the locked position to lock the second end 302 of the door body 300.

[0074] Reference Figure 4 and Figure 5 In some embodiments of the utility model, the trash bin 1000 is provided with an opening and closing mechanism 100 on both sides in the left and right directions, and a connecting member 320 is provided on the door body 300. The connecting member 320 extends along the left and right directions and extends out of the left and right sides of the door body 300, and is connected to the opening and closing mechanism 100; wherein the linear drive member 20 is transmission-connected with the connecting member 320, and is used to drive the door body 300 to open and close the door body 300; in this way, the opening and closing stability of the door body 300 can be improved by arranging the opening and closing mechanism 100 on the left and right sides.

[0075] In detail, a connecting piece 320 is provided on the door body 300 of the trash bin 1000, and the connecting piece 320 extends in the left-right direction and extends out of the left and right sides of the door body 300; therefore, the second connecting rod 32 of the left opening and closing mechanism 100 can be hinged to the left end of the connecting piece 320, and the second connecting rod 32 of the right opening and closing mechanism 100 can be hinged to the right end of the connecting piece 320; when the door body 300 is opened and closed, the opening and closing mechanisms 100 on the left and right sides can simultaneously drive the door body 300 to rotate relative to the box body 200 to open and close the box body 200, thereby improving the opening and closing stability of the door body 300.

[0076] In combination with the aforementioned embodiments, in some specific examples of the present invention, an opening and closing mechanism 100 is respectively provided on both sides of the trash bin 1000 in the left and right directions, and a fixing part 310 is provided on the door body 300. The fixing part 310 extends along the left and right directions and extends out of the left and right sides of the door body 300. The locking part 10 of the opening and closing mechanism 100 can be detachably hooked on the fixing part 310, thereby improving the sealing performance of the trash bin 1000.

[0077] In the related art, in the left and right directions of the trash bin 1000, the locking member 10 is generally arranged on the left side, right side or middle part of the trash bin 1000, and the door body 300 is locked and unlocked by the locking member 10. Such an arrangement results in poor sealing performance of the trash bin 1000, which is easy to leak waste water and the like in the trash bin 1000; while the technical solution in this embodiment can cooperate with the fixing member 310 by the locking member 10 arranged in the opening and closing mechanism 100 on the left and right sides of the trash bin 1000 to improve the sealing performance of the trash bin 1000; specifically, when the opening and closing mechanism 100 is working, the locking members 10 on the left and right sides can move upward to the locking position to respectively hook the left and right ends of the fixing member 310, thereby locking the second end 302 of the door body 300; in addition, the left and right locking members 10 can move downward to the unlocking position to respectively disengage the left and right ends of the fixing member 310, thereby unlocking the second end 302 of the door body 300.

[0078] According to the above, by arranging the opening and closing mechanism 100 on the left and right sides of the trash can 1000 respectively, the force on the door body 300 can be balanced, and the movement accuracy of the door body 300 can be improved, thereby effectively improving the sealing performance of the trash can 1000 and avoiding the problem of leakage of the trash can 1000.

[0079] Reference Figure 7 In some specific examples of the present invention, the driving force that the linear drive member 20 can provide is 600N, the straight-line distance between the first end 301 of the door body 300 and the linear drive member 20 can be 80mm, and the straight-line distance between the hinge point between the second connecting rod 32 and the door body 300 and the first end 301 of the door body 300 can be 211mm. It can be calculated through the lever balance principle that the force required for the linear drive member 20 to overcome the gravity of the door body 300 is 288.75N. Therefore, the linear drive member 20 can meet the requirements of opening and closing the door body 300 in actual applications.

[0080] Referring to Figures 1 to 7, in some specific examples of the present invention, the opening and closing mechanism 100 is mainly composed of a hinge seat, a door body 300, two connecting rods, an electric push rod, a lock hook 101, and a base slide 210. The door body 300 is composed of a rectangular tube (i.e., a connecting member 320), a door panel, and a round tube (i.e., a fixing member 310).

[0081] The opening and closing mechanism 100 controls the extension and retraction of the electric push rod to drive the two connecting rods to move, thereby controlling the opening and closing of the door body 300.

[0082] The opening process of the door body 300 is as follows:

[0083] During the opening process of the door body 300, the electric push rod extends, and under the action of gravity, the electric push rod and the lock hook 101 slide downward in the base slide groove 210, that is, Figure 1 Slide to Figure 2 The lock hook 101 is separated from the round tube of the door body 300; the electric push rod continues to extend, the electric push rod pushes the connecting rod, and the connecting rod drives the door body 300 to rotate around the hinge seat, and the door body 300 is opened and turned to Figure 3 Position shown.

[0084] Similarly, when the door body 300 is closed, the electric push rod contracts, the electric push rod drives the connecting rod to retract, and the door body 300 rotates around the hinge seat to Figure 2 The electric push rod continues to retract, and the lock hook 101 slides upward in the base slide groove 210 to Figure 1 In the position shown, the locking hook 101 locks the round tube of the door body 300, and the door body 300 is sealed.
