Background Art

[0004] As a common cargo handling and storage device, a cage cart usually includes a cage cart body for supporting and fixing goods, and a cage door that can be opened and closed for loading and unloading goods. However, when the cage door of a traditional cage cart is opened for loading and unloading operations, since the cage door is in an unloaded state, it is prone to yaw in the direction of closing. This yaw will affect the loading and unloading efficiency of the staff and increase the operation difficulty. Secondly, when the cage door is opened, it often cannot be fully unfolded outward to a state where it fits against the outer side of the cage cart body, which causes the cage door to occupy additional external space during loading and unloading, limits the operation area, and reduces the space utilization rate.

Detailed Embodiments

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the following will further elaborate on the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] Please refer to Figures 1 to 7 , a snap-in rotary connection mechanism, including a first connecting member 2 provided on the cage body 1, a second connecting member 4 provided on the cage door 3, a hinge 5 respectively hinged to the first connecting member 2 and the second connecting member 4 and allowing the cage door 3 to be unfolded outward to fit against the outer side of the cage body 1, and a snap-in mechanism 6 for respectively positioning the hinge 5 with the first connecting member 2 and the second connecting member 4.

[0032] A snap - type rotary connection mechanism of the present application, by providing a first connecting member and a second connecting member on the cage body and the cage door and cooperating with a hinge, can make the cage door unfold to fit against the outer side of the cage body. At the same time, the cage body and the cage door are kept in outer - side fit by using a snap - connection mechanism, effectively preventing the situation that the loading and unloading of goods by workers is affected due to the yaw of the cage door. It not only improves work efficiency but also reduces space occupation.

[0033] Further, as a preferred implementation manner rather than a limitation of this solution, the snap - connection mechanism 6 includes a first protrusion 61 and a first groove 62 for the first protrusion 61 to snap into. The first protrusion 61 is provided on the hinge 5 and the first groove 62 is provided on the first connecting member 2; or the first protrusion 61 is provided on the first connecting member 2 and the first groove 62 is provided on the hinge 5.

[0034] In this embodiment, it is ensured that the cage door can maintain a stable state after being opened, without yawing or automatically closing, improving the efficiency and safety of the loading and unloading operation. In addition, this snap - connection mechanism can also be flexibly adjusted according to actual needs. For example, the first protrusion is set on the first connecting member and the first groove is set on the hinge, and the effect of positioning connection can also be achieved.

[0035] Further, as a preferred implementation manner rather than a limitation of this solution, the snap - connection mechanism 6 further includes a second protrusion 63 and a second groove 64 for the second protrusion 63 to snap into. The second protrusion 63 is provided on the hinge 5 and the second groove 64 is provided on the second connecting member 4; or the second protrusion 63 is provided on the second connecting member 4 and the second groove 64 is provided on the hinge 5.

[0036] In this embodiment, the positions of the second protrusion and the second groove are interchanged, that is, the second protrusion is set on the second connecting member and the second groove is set on the hinge, and a stable connection effect can also be achieved. In addition, according to actual needs, more protrusions and grooves can be added to the snap - connection mechanism to form multi - point positioning, further enhancing the reliability of the connection.

[0037] Further, as a preferred implementation manner rather than a limitation of this solution, when the cage door 3 unfolds outward to fit against the outer side of the cage body 1, the first protrusion 61 snaps into the first groove 62, and at the same time the second protrusion 63 snaps into the second groove 64.

[0038] In this embodiment, through the cooperation of the double snap - connection mechanism, the cage door can maintain a stable position after being opened, without shifting or shaking, improving the efficiency and safety of the loading and unloading operation. At the same time, this design also enables the cage door to be fully opened without occupying extra space, improving the space utilization rate.

[0039] Further, as a preferred implementation manner rather than a limitation of this solution, the hinge 5 is in an I shape, and the hinge 5 is provided with a first installation position 51 for the first connecting member 2 to extend into, and a second installation position 52 for the second connecting member 4 to extend into.

[0040] In this embodiment, by providing the first installation position 51 and the second installation position 52 thereon, the precise positioning and fixation of the first connecting member 2 and the second connecting member 4 are achieved. This design enables the hinge 5 to evenly distribute the load when bearing the force generated during the opening and closing of the cage door 3, reducing local stress concentration, thereby improving the durability and reliability of the overall structure.

[0041] Further, as a preferred implementation manner rather than a limitation of this solution, a pin 7 is further included. The first connecting member 2 is provided with a first limiting groove 21 for a part of the first elastic member 8 to be embedded. The pin 7 penetrates through the hinge 5, the first connecting member 2, the first limiting groove 21, and the first elastic member 8 along the vertical direction at the first installation position 51. One end of the pin 7 is provided with a limiting flap 71 that abuts against the hinge 5, and the other end of the pin 7 is provided with a connection hole 72 for a fastener to pass through. The fastener passes through the connection hole 72 and cooperates with the limiting flap 71 to limit the pin 7 from disengaging from the hinge 5. A part of the first elastic member 8 is embedded in the first limiting groove 21 and both ends thereof respectively abut against the first connecting member 2 and the hinge 5.

[0042] In this embodiment, when the hinge rotates outward relative to the cage body by 90 degrees, the first protrusion slides out of the first groove and pushes the hinge to slide in the vertical direction. At the same time, the first elastic member is compressed by force. When the hinge continues to rotate outward relative to the cage body by 180 degrees, the hinge drives the first protrusion to slide into the first groove under the elastic force of the first elastic member, and the hinge resets in the vertical direction to keep the hinge positioned with the cage body. The first elastic member is a spring.

[0043] Further, as a preferred implementation manner rather than a limitation of this solution, a rotating shaft 9 is further included. The second connecting member 4 is provided with a second limiting groove 41 for a part of the second elastic member 10 to be embedded. The rotating shaft 9 penetrates through the hinge 5, the second connecting member 4, the second limiting groove 41, and the second elastic member 10 along the vertical direction corresponding to the second installation position 52. An opening 91 is provided on the rotating shaft 9, and a positioning hole 53 for a fastener to pass through is provided on the hinge 5 corresponding to the opening 91. The fastener passes through the positioning hole 53 and the opening 91 to connect the hinge 5 and the rotating shaft 9. A part of the second elastic member 10 is embedded in the second limiting groove 41 and both ends thereof respectively abut against the second connecting member 4 and the hinge 5. The second elastic member is a spring.

[0044] In this embodiment, when the cage door rotates outward relative to the hinge by 90 degrees, the second protrusion slides out of the second groove and pushes the hinge to slide in the vertical direction. At the same time, the second elastic member is compressed. When the hinge continues to rotate outward relative to the cage body by 180 degrees, the hinge drives the second protrusion to slide into the second groove under the elastic force of the second elastic member, and the hinge resets in the vertical direction to position the cage door and the hinge. At this time, the cage door can be unfolded outward to the outside of the cage body.

[0045] Further, as a preferred implementation manner of this solution rather than a limitation, the opening direction of the first limiting groove 21 on the first connecting member 2 is opposite to the direction of the first groove 62 on the first connecting member 2.

[0046] In this embodiment, the design that the opening direction of the first limiting groove 21 on the first connecting member 2 is opposite to the direction of the first groove 62 provides an effective space utilization and function differentiation. The first limiting groove 21 complements the first groove 62 in structure. When the first protrusion 61 disengages from the first groove 62, the first limiting groove 21 can serve as an auxiliary guide to smoothly guide the first protrusion 61 to disengage, reducing the operation difficulty and improving the operation accuracy, and also providing a place for the first elastic member to be installed for elastic compression.

[0047] Further, as a preferred implementation manner of this solution rather than a limitation, the opening direction of the second limiting groove 41 on the second connecting member 4 is opposite to the direction of the second groove 64 on the second connecting member 4.

[0048] In this embodiment, the design that the opening direction of the second limiting groove 41 on the second connecting member 4 is opposite to the direction of the second groove 64 provides an effective space utilization and function differentiation. The second limiting groove 64 complements the second groove 64 in structure. When the second protrusion 63 disengages from the second groove 64, the second limiting groove 41 can serve as an auxiliary guide to smoothly guide the second protrusion 63 to disengage, reducing the operation difficulty and improving the operation accuracy, and also providing a place for the second elastic member to be installed for elastic compression.

[0049] Further, as a preferred implementation manner of this solution rather than a limitation, the first groove 62 on the first connecting member 2 and the second groove 64 on the second connecting member 4 are arranged in opposite directions.

[0050] In this embodiment, when the cage door is fully opened and fits against the outside of the cage body, the first protrusion and the second protrusion can be simultaneously engaged in the corresponding grooves to form a stable connection. This ensures that the cage door will not rotate or shake after being opened, improving the stability and reliability of the cage door.

[0051] The working principle of this embodiment is as follows:

[0052] A snap - type rotary connection mechanism of the present application, by setting a first connecting member and a second connecting member on the cage body and the cage door and cooperating with a hinge, can make the cage door unfold to fit the outer side of the cage body. At the same time, the snap - connection mechanism is used to keep the cage body and the cage door in outer - side fit, effectively preventing the situation that the loading and unloading of goods by workers is affected due to the yaw of the cage door. It not only improves work efficiency but also reduces space occupation.
