[0036] Embodiments

[0037] The embodiments of the present application provide a quick-opening door interlocking structure, which is combined with Figure 1 and Figure 2 As shown in the drawings, the quick-opening door interlocking structure comprises a base 1, a first connecting piece 2, a second connecting piece 3 and a linkage mechanism 4.

[0038] The first connecting piece 2 is used to support an external structure, and the second connecting piece 3 is used to connect the external structure. The first connecting piece 2 is provided with an inner tooth groove 21, and the second connecting piece 3 is provided with an outer tooth groove 31 matched with the inner tooth groove 21.

[0039] Specifically, in some embodiments of the present application, a plurality of tooth portions 310 are respectively arranged on the inner tooth groove 21 and the outer tooth groove 31 in a circumferential direction, and a groove portion 210 is formed between adjacent two tooth portions 310, i.e., the tooth portions 310 and the groove portions 210 are arranged in an interval.

[0040] The linkage mechanism 4 and the first connecting piece 2 are both arranged on the base 1. The first connecting piece 2 is movably sleeved on the second connecting piece 3. The linkage mechanism 4 is drivenly connected with the first connecting piece 2, so as to switch the quick-opening door interlocking structure between a locked state and an unlocked state.

[0041] The tooth portion 30 of the outer tooth groove 31 is used to abut against the tooth portion 30 of the inner tooth groove 21 in the locked state, so that the first connecting piece 2 stops the second connecting piece 2, and the external structure is fixed on the base 1.

[0042] The tooth portion 310 of the outer tooth groove 31 in the locked state is at least partially used to abut against the tooth portion 310 of the inner tooth groove 21, so that the first connecting piece 2 stops the second connecting piece 3.

[0043] Specifically, the tooth portion 310 of the outer tooth groove 31 in the locked state is at least partially used to abut against the tooth portion 310 of the inner tooth groove 21, i.e., at least a part of the tooth portion 310 of the outer tooth groove 31 overlaps with the tooth portion 310 of the inner tooth groove 21.

[0044] The groove portion 210 of the inner toothed groove piece 21 corresponds to the tooth portion 310 of the outer toothed groove piece 31 in the unlocked state, so that the first connecting piece 2 avoids the second connecting piece 3, allowing the external structure to be freely movable relative to the base 1 in the axial direction.

[0045] The groove portion 210 of the inner toothed groove piece 21 corresponds to the tooth portion 310 of the outer toothed groove piece 31 in the unlocked state, so that the first connecting piece 2 avoids the second connecting piece 3, allowing the external structure to be freely movable relative to the base 1 in the axial direction.

[0046] Specifically, the groove portion 210 of the inner toothed groove piece 21 corresponds to the tooth portion 310 of the outer toothed groove piece 31 in the unlocked state, that is, the entire tooth portion 310 of the outer toothed groove piece 31 is located in the groove portion 210 of the inner toothed groove piece 21, and the entire tooth portion 310 of the inner toothed groove piece 21 is located in the groove portion 210 of the outer toothed groove piece 31, and the outer toothed groove piece 31 is embedded with the inner toothed groove piece 21.

[0047] It can be understood that, through the linkage mechanism 4, the position change of the inner toothed groove piece 21 and the outer toothed groove piece 31 is realized, so that the quick-opening door interlocking structure can be quickly locked and unlocked, and the structural response speed is improved; in the locked state, the tooth portion 310 of the outer toothed groove piece 31 and the tooth portion 310 of the inner toothed groove piece 21 are in butt joint interlock, which can effectively stop the movement of the external structure connected with the second connecting piece 3 in the vertical direction, prevent the external structure from being separated from the second connecting piece 3, and enhance the safety in use; and in the unlocked state, the outer toothed groove piece 31 and the inner toothed groove piece 21 avoid each other, so that the first connecting piece 2 and the second connecting piece 3 can smoothly slide, which is convenient for unlocking and improves the simplicity of operation.

[0048] The external structure can be a static container 5, and the specific form and function of the external structure are not limited.

[0049] The design of the quick-opening door interlocking structure is relatively simple, which reduces the manufacturing difficulty and cost. The design of the inner toothed groove piece 21 and the outer toothed groove piece 31 also reduces the wear caused by friction in the traditional locking structure. Only in the case of a specific force, such as the movement of the second connecting piece 3 in the direction of separating from the first connecting piece 2, which can be axial movement, the outer toothed groove piece 31 and the inner toothed groove piece 21 will be in abutment, preventing the separation of the first connecting piece 2 and the second connecting piece 3. Therefore, the wear problem in long-term use can be effectively reduced, thereby improving the service life and durability of the structure.

[0050] More specifically, the degree of overlap of the tooth portion 310 of the outer tooth groove member 31 and the inner tooth groove member 21 is different, and the locking force generated is also different. When the degree of overlap of the tooth portion 310 of the outer tooth groove member 31 and the inner tooth groove member 21 is higher, the locking force that can be generated is greater, and the stability is stronger. When the degree of overlap of the tooth portion 310 of the outer tooth groove member 31 and the inner tooth groove member 21 is lower, the locking force that can be generated is smaller, and the stability is weaker. By adjusting the degree of overlap of the tooth portion 310 of the outer tooth groove member 31 and the inner tooth groove member 21, the stability and locking strength of the quick-opening door interlocking structure can also be adjusted, thereby better adapting to different application scenarios.

[0051] Further, the width of the groove portion 210 is not less than the width of the tooth portion 310.

[0052] Specifically, in some embodiments of the present application, the width of the groove portion 210 of the inner tooth groove member 21 is not less than the width of the tooth portion 310 of the outer tooth groove member 31, and the width of the groove portion 210 of the outer tooth groove member 31 is not less than the width of the tooth portion 310 of the inner tooth groove member 21.

[0053] Illustratively, in some embodiments of the present application, the width of the groove portion 210 of the inner tooth groove member 21 is greater than the width of the tooth portion 310 of the outer tooth groove member 31, and the width of the groove portion 210 of the outer tooth groove member 31 is greater than the width of the tooth portion 310 of the inner tooth groove member 21.

[0054] As can be understood, when the width of the groove portion 210 is greater than or equal to the width of the tooth portion 310, on the one hand, the tooth portion 310 can pass through the groove portion 210 more freely, thereby avoiding the phenomenon of jamming and helping to achieve smooth operation of the structure. The wider design of the groove portion 210 also helps to reduce friction between the tooth portion 310 and the groove portion 210, reducing wear.

[0055] On the other hand, the wider groove portion 210 provides a larger fault tolerance space, and does not require precise alignment of the tooth portion 310 and the groove portion 210. As long as the tooth portion 310 is within the range of the groove portion 210, it can enter the unlocked state, thereby improving the convenience of operation.

[0056] Further, as shown in the drawings, the cross-sectional shape of the first connecting member 2 and / or the second connecting member 3 includes a ring shape. Figure 1

[0057] Specifically, in some embodiments of the present application, the shape of the inner tooth groove member 21 and the first connecting member 2, and the shape of the outer tooth groove member 31 and the second connecting member 3 are matched, and the shapes of the inner tooth groove member 21 and the outer tooth groove member 31 are ring-shaped.

[0058] Of course, the shapes of the first connecting member 2, the second connecting member 3, the inner tooth groove member 21, and the outer tooth groove member 31 are not limited.

[0059] ​It can be understood that the annular shape can make the stress of the first connecting piece 2 and the second connecting piece 3 more uniform, thereby avoiding local stress concentration, reducing structural deformation and stress concentration phenomenon, and obtaining higher carrying capacity, thereby improving the strength and stability of the first connecting piece 2 and the second connecting piece 3.

[0060] Further, the tooth portion 310 located at the outer tooth groove piece 31 presents a shrinking trend from inside to outside in the radial direction, and the tooth portion 310 located at the inner tooth groove piece 21 presents a shrinking trend from outside to inside in the radial direction.

[0061] It can be understood that the tooth portion 310 shrinks in the radial direction, which helps the first connecting piece 2 to smoothly avoid the second connecting piece 3, reduces the occurrence of jamming phenomenon, also reduces the friction and wear between the tooth surfaces, makes the unlocking operation more smooth, and can effectively prolong the service life.

[0062] The shape and structure design of the tooth portion 310 can effectively tolerate slight misalignment, thereby further improving the fault tolerance of the system.

[0063] Further, as shown in Figure 3 The linkage mechanism 4 is provided on the base 1 through the first rotating portion 41, the output end of the linkage mechanism 4 is connected with the acting portion 43 through the second rotating portion 42, and the acting portion 43 is used to transmit the acting force of the linkage mechanism 4 to the first connecting piece 2.

[0064] Specifically, in some embodiments of the present application, the first rotating portion 41 makes the linkage mechanism 4 rotate around the first rotating shaft relative to the base 1, and the second rotating portion 42 makes the acting portion 43 rotate around the second rotating shaft relative to the main body of the linkage mechanism 4;

[0065] Wherein, the extension directions of the first rotating shaft and the second rotating shaft are non-parallel;

[0066] More specifically, the extension directions of the first rotating shaft and the second rotating shaft are perpendicular;

[0067] Of course, the extension directions of the first rotating shaft and the second rotating shaft are not limited.

[0068] It can be understood that the first rotating portion 41 and the second rotating portion 42 are provided, so that the structure is more compact, space is saved, and the overall layout of the quick-opening door interlocking structure is optimized; the linkage mechanism 4 is connected through the first rotating portion 41 and the second rotating portion 42, and the extension directions of the first rotating shaft and the second rotating shaft are non-parallel, which is convenient for adjusting the acting angle and acting force of the linkage mechanism 4, enhances the flexibility of the linkage mechanism 4, and can adjust the first rotating portion 41 and the second rotating portion 42 according to the demand, so that the motion transmission and operation are more accurate and efficient.

[0069] Exemplarily, the main body of the linkage mechanism 4 can be realized by a pneumatic cylinder or an electric motor, and the specific implementation of the linkage mechanism 4 is not limited.

[0070] Further, as shown in Figure 3 the outer wall of the first connecting piece 2 is provided with a connecting groove 22 matched with the shape of the acting part 43.

[0071] Understandably, the connecting groove 22 is matched with the shape of the acting part 43, which helps to realize the accurate butt joint between the first connecting piece 2 and the acting part 43, enhances the fixing effect of the connecting groove 22 and the acting part 43, and improves the stability and reliability of the connection; the acting part 43 can abut against the groove wall of the connecting groove 22, which increases the force point, and further helps the acting force of the linkage mechanism 4 to be smoothly transmitted to the first connecting piece 2.

[0072] Further, the acting part 43 includes a first acting block 431 and a second acting block 432, the first acting block 431 connects the first connecting piece 2 and the second acting block 432, and the second acting block 432 connects the second rotating part 42. The second acting block 432 is at least partially located outside the projection of the first acting block 431 on the first connecting piece 2 to form a limiting part 433 for limiting the first connecting piece 2.

[0073] Understandably, the second acting block 432 is located outside the projection of the first acting block 431 on the first connecting piece 2 to form a limiting part 433, which helps to avoid the problem of falling or displacement of the acting part 43 and the first connecting piece 2 during use, and the existence of the limiting part 433 can abut against the first connecting piece 2 when the acting part 43 and the first connecting piece 2 are displaced or about to be displaced, as an additional force point, to a certain extent, to maintain the connection between the acting part 43 and the first connecting piece 2, thereby further enhancing the connection stability and reliability.

[0074] More specifically, the first acting block 431 is provided with a plurality of connecting holes 430 for connecting the second acting block 432, and the connecting holes 430 are provided in multiple groups for changing the connection position of the first acting block 431 and the second acting block 432, so as to realize the adjustment of the acting force direction and the acting angle of the linkage mechanism 4.

[0075] Further, as shown in Figure 1 and Figure 4 the inner wall of the first connecting piece 2 is further provided with a supporting part 23 for supporting the external structure.

[0076] Specifically, in some embodiments of the present application, the supporting part 23 extends to the central area in a radial direction in a stepped manner.

[0077] Understandably, the supporting part 23 is designed by a stepped structure, which can effectively disperse the load applied by the external structure, reduce the concentrated stress, thereby improving the carrying capacity of the first connecting piece 2, and helping to improve the stability and safety of the first connecting piece 2 under high load conditions.

[0078] The stepped supporting part 23 can provide a larger contact area, better fit with the external connecting piece, make the contact between the external structure and the connecting piece more stable, and help to reduce loosening or displacement during use, and improve the stability of the overall connection.

[0079] The embodiments of the present application also provide a container, which combines Figure 4 With Figure 5 As shown, the quick-opening door interlocking structure of any one of the preceding embodiments.

[0080] Specifically, in some embodiments of the present application, the container 5 is barrel-shaped and can be used for standing batteries;

[0081] Of course, the specific form of the container 5 is not limited;

[0082] By setting the quick-opening door interlocking structure, quick locking and unlocking with the base 1 is achieved, which enhances the connection stability while obtaining good locking and unlocking convenience.

[0083] The embodiments of the present application at least have the following beneficial effects:

[0084] The embodiments of the present application provide a quick-opening door interlocking structure and a container having the same, which has good stability, simplifies the interlocking structure, facilitates quick locking and unlocking of the interlocking structure, reduces frequent wear between components of the interlocking structure, and improves the service life of the interlocking structure; Specifically, the locking and unlocking of the structure can be achieved by changing the positional relationship between the inner tooth groove piece 21 and the inner tooth groove piece 21, the structure is simple and convenient to operate, the locking and unlocking speed is improved, and the teeth 310 of the outer tooth groove piece 31 in the locked state at least partially abut the teeth 310 of the inner tooth groove piece 21. On the one hand, the outer tooth groove piece 31 only abuts the inner tooth groove piece 21 when subjected to a specific external force, thereby reducing the occurrence of wear. On the other hand, the outer tooth groove piece 31 can be locked as long as part of the teeth 310 abut the teeth 310 of the inner tooth groove piece 21, which has a large fault tolerance range and can effectively adjust the locking strength.
