Technical Field

[0001] This utility model belongs to the field of lantern assembly technology, and in particular relates to a lantern mounting base and lantern frame structure. Background Technology

[0002] Lanterns vary in size depending on their intended use. They have internal cavities, which take up a lot of space during transportation. Currently, the common method is to fold or disassemble the lanterns and then assemble them. However, the existing lantern frame structure is complex, and the keel and connecting base are bound together with iron wire, resulting in low assembly efficiency, easy damage, and short service life. Utility Model Content

[0003] In view of the above problems, this utility model provides a lantern mounting base and lantern frame structure to solve the above or other problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a lantern mounting base, including a mounting body and a connecting component disposed on the mounting body, the connecting component being used to connect with multiple keels, and the connecting component being rotatable relative to the mounting body; wherein,

[0005] The connecting assembly includes a connector, a connector seat disposed on the connector, and a fixing member. There are multiple connector seats, which are intersecting with the connector. The multiple connector seats are arranged sequentially along the circumferential direction of the connector. The corresponding ends of the multiple connector seats are located on the same side of the connector. The fixing members are respectively connected to both ends of the connector so that the connector is circumferentially mounted on the mounting body.

[0006] Furthermore, one end of the connector is provided with a mounting hole, which is coaxially arranged with the connector, and the other end of the connector is provided with a curved transition structure to reduce the contact area between the connector and the mounting body during rotation.

[0007] Furthermore, a limiting element is provided on the side of the connector facing the mounting body to limit the installation of the connector.

[0008] Furthermore, the side of the connector opposite to the side with the limiting member is provided with a planar structure so that the connector can contact and cooperate with the mounting body when the connector is in the second state.

[0009] Furthermore, the connector is positioned perpendicular to the connector.

[0010] Furthermore, the fastener includes a first plug-in component and a second plug-in component that are connected by plugging in. The first plug-in component is fixedly connected to one end of the connector, and the second plug-in component is fixedly connected to the other end of the connector. The first plug-in component has a plug-in hole, and a locking block is provided on the inner side wall of the plug-in hole. The second plug-in slot has a locking groove, and the locking block is plugged into the locking groove.

[0011] Furthermore, the mounting body is provided with a circumferential receiving groove and multiple axial receiving grooves. The circumferential receiving groove is arranged along the circumferential direction of the mounting body to accommodate the connecting parts. The axial receiving groove is arranged along the axial direction of the mounting body, and multiple axial receiving grooves intersect and are connected to the circumferential receiving groove. The multiple axial receiving grooves are arranged sequentially along the circumferential direction of the mounting body to accommodate the connecting seats.

[0012] Furthermore, the axial receiving groove is connected to an axial end face of the mounting body, so that the connecting seat located in the axial receiving groove extends out of the axial end face of the mounting body. The axial receiving groove is connected to the outer peripheral side of the mounting body, so that the connecting seat can rotate in the outward direction of the mounting body.

[0013] Furthermore, the connector, connector base, and fastener are integrally molded.

[0014] A lantern frame structure includes multiple keels and a lantern mounting base as described above. Each keel has a lantern mounting base at both ends, and each keel is connected to a lantern mounting base. The multiple keels are arranged sequentially along the circumference of the lantern mounting base.

[0015] Furthermore, it also includes a first central tube, a second central tube, and a positioning device. The first central tube is connected to a mounting base, and the second central tube is connected to another mounting base. The first central tube and the second central tube are inserted into each other and can slide relative to each other. The positioning device is located on the mounting base connected to the first central tube and is also connected to the second central tube. The positioning device positions the relative position between the first central tube and the second central tube so that the lantern frame structure can switch between a closed state and an open state.

[0016] Furthermore, the positioning device includes a snap-fit ​​component, a receiving component connected to the snap-fit ​​component, an abutment component disposed on the receiving component, a positioning component disposed on the mounting base, and an end cap. The snap-fit ​​component is connected to the second middle tube, the abutment component can slide relative to the receiving component, the end cap is disposed on the mounting base, and the end cap and the mounting base form an accommodating space. The positioning component is disposed within the accommodating space and is disposed on opposite radial sides of the receiving component. The positioning component can move along the radial direction of the receiving component, extend out of the accommodating space, and abut against the receiving component, so that the lantern frame structure is in the open state. When the abutment component contacts and engages with the positioning component, the positioning component moves into the accommodating space, thereby closing the lantern frame structure.

[0017] Furthermore, the receiving component includes a receiving part, a connecting part, and a snap-fit ​​part arranged coaxially. The receiving part, the connecting part, and the snap-fit ​​part are connected in sequence. The diameter of the receiving part is larger than the diameter of the connecting part, and the diameter of the connecting part is larger than the diameter of the snap-fit ​​part. The abutment is fitted onto the connecting part, and the snap-fit ​​part snaps into the snap-fit ​​part. The abutment moves within the axial length range of the connecting part.

[0018] Furthermore, the outer diameter of one end of the abutment is larger than the outer diameter of the other end, the outer diameter of the large diameter end of the connector is adapted to the outer diameter of the receiving part, and the outer diameter of the small diameter end of the connector is smaller than the outer diameter of the snap-fit ​​part.

[0019] Furthermore, the positioning element is provided with an elastic element so that the positioning element can be reset under the action of the elastic element.

[0020] Furthermore, the snap-fit ​​component includes a limiting part, a fixing part, and a plugging part coaxially arranged. The limiting part, the fixing part, and the plugging part are connected in sequence. The outer diameter of the limiting part is smaller than the outer diameter of the fixing part, and the outer diameter of the fixing part is larger than the outer diameter of the plugging part. The plugging part is fixedly connected to the second middle tube. The outer diameter of the plugging part is adapted to the inner diameter of the second middle tube, and the outer diameter of the fixing part is adapted to the inner diameter of the first middle tube. The limiting part, the fixing part, and the plugging part all have through holes that communicate with each other, so that the snap-fit ​​component can be plugged into the receiving component. The second middle tube, the snap-fit ​​component, the receiving component, and the abutment component are coaxially arranged.

[0021] Due to the adoption of the above technical solution, the lantern mounting base has a simple structure, with a connecting component and a mounting body. The connecting component is set on the mounting body and can rotate relative to the mounting body. The connecting component is an integral structure with mounting holes for mounting to the keel. Simply connect the keel to the connecting component to complete the assembly of the mounting base and the keel. It is easy to assemble and use, not easy to be damaged, and the integral structure of the connecting component has a long service life.

[0022] The mounting body is equipped with a circumferential receiving groove and multiple axial receiving grooves, which can accommodate the connectors and connecting seats of the connecting components, so that the connectors and connecting seats are always located on the mounting body during rotation and will not fall off the mounting body, thus ensuring the structural stability of the lantern frame structure during the opening and closing process.

[0023] The multiple connectors can connect multiple keels together to form an overall structure of lantern frame with the mounting base. The connectors are equipped with limiters to limit the distance between the connector and the mounting body, and also to position the connectors. This provides sufficient space for the connectors to rotate, ensuring that the connectors can rotate on the mounting body and allowing the connectors to switch positions between the first and second states.

[0024] The curved transition structure ensures that the contact between the connecting seat and the bottom wall of the axial receiving groove is a line contact or point contact during rotation, reducing the resistance encountered by the connecting seat during rotation.

[0025] The planar structure design ensures that when the connecting seat is in the second state, the contact between the planar structure and the axial sidewall of the axial receiving groove is a surface contact, so that the axial sidewall of the axial receiving groove can support the connecting seat and maintain the stability of the lantern frame structure when the connecting seat is in the second state.

[0026] The lantern frame structure is equipped with a positioning device, a first central tube, and a second central tube. The positioning device can lock the positions of the first and second central tubes to keep the lantern frame structure in the open state, and it can also unlock the positions of the first and second central tubes to close the lantern frame structure. The positioning device has a receiving part, a blocking part, and a positioning part. The opening and closing states of the lantern frame structure are switched through the cooperation of the receiving part and the positioning part and the blocking part. Attached Figure Description

[0050] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0051] Figure 1A schematic diagram of an embodiment of the present invention is shown. This embodiment relates to a lantern mounting base and a lantern frame structure. The lantern mounting base has a connecting component and a mounting body. The connecting component is detachably mounted on the mounting body and is an integral structure. The connecting component is connected to the keel and can rotate relative to the mounting body to adapt to changes in the curvature of the keel. The mounting base has a simple structure, is easy to manufacture and assemble, and has a long service life.

[0052] A mounting base 1 for a lantern, such as Figure 1-4 As shown, the mounting base 1 is installed at both ends of the keel 2, connecting multiple keels 2 into a single structure to form the lantern frame. Specifically, the mounting base 1 includes a mounting body 10 and a connecting component 11 disposed on the mounting body 10. The connecting component 11 can rotate relative to the mounting body 10 to adapt to changes in the curvature of the keels, thereby adapting to the open and closed states of the lantern. The mounting body 10 serves to support the frame and supports the connecting component 11, facilitating its installation. The connecting component 11 can be installed on the mounting body 10 to construct the overall structure of the mounting base 1. The connecting component 11 is used to connect with multiple keels 2, so that the multiple keels 2 are arranged sequentially along the circumferential direction of the mounting body 10, connecting the multiple keels 2 together to form a single structure, thus constituting the lantern's frame structure. By rotating the connecting component 11, it adapts to different curvatures of the keels 2, adapting to the closed or open state of the lantern. Through the setting of the connecting component 11, multiple keels 2 are connected together, making the mounting base 1 simple in structure and convenient to use and assemble.

[0053] During installation, the mounting body 10 and the connecting component 11 are arranged along the circumferential direction of the mounting body 10 and are coaxially arranged with the mounting body 10. This allows multiple keels 2 arranged on the connecting component 11 to be arranged sequentially along the circumferential direction of the mounting body 10, and the skeleton structure formed by the multiple keels 2 is coaxially arranged with the mounting body 10, so that the lantern skeleton structure is stable and has an aesthetically pleasing shape.

[0054] like Figure 3 , 4 As shown in Figures 6 and 7, the aforementioned connecting assembly 11 includes a connector 110, a connecting seat 111 disposed on the connector 110, and a fixing member 112. The connector 110 is disposed on the mounting body 10 so that the connecting assembly 11 is entirely disposed on the mounting body 10. The placement of the connector 110 facilitates the installation of the connecting seat 111, so that the connecting seat 111 is also located on the mounting body 10. The connector 110 can rotate relative to the mounting body 10, thereby causing the connecting seat 111 disposed on the connector 110 to rotate relative to the mounting body 10. The connector 110 is disposed along the circumferential direction of the mounting body 10 and is circumferentially disposed on the mounting body 10. The connector 110 and the mounting body 10 are coaxially disposed.

[0055] The connecting seat 111 is used to connect with the keel 2. There are multiple connecting seats 111, one connecting seat 111 is connected to one keel 2, and multiple connecting seats 111 are all connected to the connector 110. That is, multiple connecting seats 111 are all set on the connector 110. Multiple connecting seats 111 are arranged sequentially along the circumferential direction of the connector 110 and are arranged around the circumferential side of the mounting body 10. Then multiple keels 2 are arranged sequentially along the circumferential direction of the mounting body 10. Multiple connecting seats 111 can be arranged at equal intervals along the circumferential direction of the connector 110 or not at equal intervals, depending on the actual needs. In order to make the lantern look beautiful, it is preferable that multiple connecting seats 111 are arranged at equal intervals, so that multiple keels 2 are arranged at equal intervals along the circumferential direction of the mounting body 10.

[0056] The connecting seat 111 is arranged along the axial direction of the connector 110 so that the connecting seat 111 is connected to the keel 2, and the keel 2 is arranged along the axial direction of the connecting seat 111, thereby making the keel 2 arranged along the axial direction of the mounting body 10.

[0057] The aforementioned fasteners 112 are respectively connected to both ends of the connector 110, connecting the two ends of the connector 110 together to form a ring structure, so that the connector 110 is fitted onto the mounting body 10, thereby realizing the connection between the connecting component 11 and the mounting body 10.

[0058] The aforementioned connector 110 is a rod-shaped structure with a certain length, allowing it to be arranged circumferentially around the mounting body 10. The cross-sectional shape of the connector 110 can be circular, square, elliptical, or other shapes, selected according to actual needs; no specific requirements are specified here. In some feasible embodiments, preferably, the cross-sectional shape of the connector 110 is circular, ensuring structural stability under bending deformation, reducing damage, and extending service life. The length of the connector 110 is selected based on the circumferential length of the mounting body 10; no specific requirements are specified here.

[0059] When the connecting seat 111 is connected to the connecting member 110, it can be that the connecting seat 111 has a through hole, and the connecting seat 111 passes through the through hole and is fixedly connected to the connecting member 110. Alternatively, there can be multiple connecting members 110, and each connecting member 110 has its two ends fixedly connected to a connecting seat 111, forming a ring-shaped connecting assembly 11 structure. The connection method between the connecting seat 111 and the connecting member 110 can be selected according to actual needs, and no specific requirements are made here.

[0060] The connecting seat 111 is fixedly connected to the connecting member 110. The positions of each connecting seat 111 are fixed along the circumferential direction of the connecting member 110. Multiple connecting seats 111 and the connecting member 110 form an integral structure, allowing multiple connecting seats 111 to rotate simultaneously with the rotation of the connecting member 110, and to move simultaneously. The fixed connection method between the connecting seat 111 and the connecting member 110 can be integral molding, such as injection molding; or, the connecting seat 111 can pass through the connecting member 110 and be connected via an interference fit through a shaft hole; or, the connecting seat 111 can pass through the connecting member 110 and be fixedly connected by bolts or other fasteners; or, the connecting seat 111 and the connecting member 110 can be connected by threads; or other fixed connection methods can be selected according to actual needs. No specific requirements are specified here.

[0061] In some feasible embodiments, preferably, the connector 111 and the connector 110 are integrally formed, which makes the structure stable, not easy to deform, has a long service life, and is easy to manufacture and use without assembly, making the structure of the mounting base 1 simple and easy to use.

[0062] The aforementioned connecting seat 111 is a rod structure with a certain length. The connecting seat 111 is fixedly mounted on the connecting member 110. The axis of the connecting seat 111 intersects with the connecting member 110. The connecting seat 111 is arranged along the radial direction of the connecting member 110. The two ends of the connecting seat 111 are respectively located on both sides of the connecting member 110, and the corresponding ends of multiple connecting seats 111 are all located on the same side of the connecting member 110. Along the circumferential direction of the connecting member 110, each connecting seat 111 is located on the same circumferential surface. That is, each connecting seat 111 is arranged along the same radial direction of the connecting member 110. The included angle between each connecting seat 111 and the connecting member 110 is the same, so that when multiple connecting seats 111 rotate with the connecting member 110, when rotated to any angle, each connecting seat 111 is located in the same circumferential surface.

[0063] The cross-sectional shape of the connector 111 can be circular, elliptical, square, or other shapes, depending on the actual needs; no specific requirements are specified here. The axial length of the connector 111 is selected and set according to the axial thickness of the mounting body 10; no specific requirements are specified here. Preferably, in some feasible embodiments, the cross-sectional shape of the connector 111 is circular, which facilitates the connection between the connector 111 and the mounting body 10.

[0064] Along the axial direction of the connecting seat 111, one end of the connecting seat 111 is provided with a mounting hole 113. The mounting hole 113 is set along the axial direction of the connecting member 110 so that the keel 2 can be inserted into the mounting hole 113 to realize the plug-in connection between the connecting seat 111 and the keel 2. The mounting hole 113 is a blind hole structure, and the depth of the mounting hole 113 is less than the axial length of the connecting seat 111 so that one end of the keel 2 can be inserted into the mounting hole 113 and the insertion depth of the keel 2 can be limited. When the mounting hole 113 is set, the axis of the mounting hole 113 coincides with the axis of the connecting seat 111, that is, the mounting hole 113 and the connecting seat 111 are coaxially set so that the keel 2 and the connecting seat 111 are coaxially set. The mounting hole 113 is formed by recessing one end of the connecting seat 111 inward along the axial direction of the connecting seat 111. The shape of the mounting hole 113 is adapted to the shape of the keel 2. The axial depth of the mounting hole 113 is selected according to actual needs and no specific requirements are made here. However, the axial end of the connecting seat 111 with the mounting hole 113 protrudes from an axial end face of the mounting body 10 so that the mounting body 10 will not interfere with the keel 2 when the connecting seat 111 is connected to the keel 2, so that the keel 2 can be quickly installed on the connecting seat 111 and the installation operation is convenient.

[0065] The end of the connector 111 that contacts the mounting body 10 is provided with a curved transition structure 116. That is, the other axial end of the connector 111 (the end away from the mounting hole 113) is a curved transition structure 116, so that when this end of the connector 111 contacts the mounting body 10, it is a line contact or a point contact, so that the resistance is small and the rotation is smooth during the rotation of the connector 111 relative to the mounting body 10, thereby realizing the transformation of the connector 111 from the first state to the second state. Here, in the first state, the axis of the connecting seat 111 is parallel to the axis of the mounting body 10. At this time, the axis of the connecting seat 111 is perpendicular to the axial end face of the mounting body 10. Consequently, the axis of the keel 2 is parallel to the axis of the mounting body 10. The keel 2 is in a vertical state with a small degree of curvature, and the lantern frame is in a closed state. In the second state, the axis of the connecting seat 111 intersects with the axis of the mounting body 10, preferably perpendicularly. At this time, the connecting seat 111 is arranged along the radial direction of the mounting body 10. The keel 2 is in a bent state with a large degree of curvature, and the lantern frame is in an open state.

[0066] The curved transition structure 116 is disposed on the other end face of the connecting seat 111 along the axial direction. It is formed by curving the end face. The curved transition structure 116 is an arc surface structure, a spherical structure, or a hemispherical structure. The contact between this end of the connecting seat 111 and the mounting body 10 is a line contact or a point contact. The resistance is small when the connecting seat 111 rotates relative to the mounting body 10. When the curved transition structure 116 is an arc surface structure, the arc length direction of the arc surface structure is set along the rotation trajectory of the curved transition structure 16 during the rotation of the connecting seat 111, so that the contact between the curved transition structure 116 and the mounting body 10 is always a line contact during the rotation of the connecting seat 111.

[0067] In some feasible embodiments, preferably, the other end face of the connecting seat 111 is an arc surface structure, which is formed by the smooth transition of the side of the connecting seat 111 facing the outside of the mounting seat 1 to the opposite side.

[0068] A limiting member 114 is provided on the side of the connector 111 facing the mounting body 10 to limit the installation of the connector 110. The limiting member 114 is disposed on the peripheral side of the connector 111, and protrudes from the peripheral side of the connector 111. When the axis of the connector 111 is parallel to the axis of the mounting body 10, the limiting member 114 contacts the mounting body 10, and the peripheral side of the connector 111 does not... The connecting seat 111 contacts the mounting body 10. At the same time, the setting of the limiting member 114 makes a certain gap between the peripheral side of the connecting seat 111 and the mounting body 10, providing a certain space for the rotation of the connecting seat 111 relative to the mounting body 10. This ensures that when the connecting seat 111 rotates relative to the mounting body 10, the side of the mounting body 10 corresponding to the side with the limiting member 114 will not interfere with the rotation of the connecting seat 111, nor will it hinder the rotation of the end of the connecting seat 111 with the curved transition structure 116.

[0069] The limiting member 114 is a block structure, arranged along the radial direction of the connecting seat 111. The limiting member 114 has a certain thickness, which is selected according to actual needs to control the distance between the side of the connecting seat 111 and the corresponding side of the mounting body 10 (the bottom wall 103 of the axial receiving groove 101). The limiting member 114 is fixedly connected to the connecting seat 111. This fixed connection method can be integral molding, fixed connection by fasteners such as screws, plug-in, threaded connection, or other fixed connection methods, selected according to actual needs. No specific requirements are specified here.

[0070] The number of limiting members 114 is at least one. When there are multiple limiting members 114, the multiple limiting members 114 are arranged in multiple rows and columns along the axial direction and / or circumferential direction of the connecting seat 111. The number of limiting members 114 is selected according to actual needs, and no specific requirements are made here.

[0071] A planar structure 115 is provided on the side of the connecting seat 111 opposite to the side where the limiting member 114 is provided, so that when the connecting seat 111 is in the second state, the connecting seat 111 contacts and engages with the mounting body 10, so that the connecting seat 111 is under balanced and stable force when it is in the second state. That is, the side of the connecting seat 111 facing the radially outward direction of the mounting body 10 is a plane, so that when the connecting seat 111 rotates to the second state, the planar structure 115 contacts the mounting body 10, and this contact is a surface contact. The keel 2 is in a state of large curvature. The mounting body 10 supports the connecting seat 111 and restricts the rotation of the connecting seat 111, thus confining the connecting seat 111 to the second state.

[0072] Along the axial direction of the connecting seat 111, the length of the planar structure 115 is less than the length of the connecting seat 111. The planar structure 115 can be formed by flattening the peripheral side surface of the connecting seat 111, or the planar structure 115 can be a plate structure, fixedly installed on the side surface of the connecting seat 111. This fixed connection method is preferably integrally formed. The planar structure 115 is installed on the peripheral side surface of the end near the connecting seat 111 where the curved transition structure 116 is located. The planar structure 115 can be connected to the curved transition structure 116, so that the connection between the planar structure 115 and the curved transition structure 116 is smoothed, so that when the connecting seat 111 is in the second state, the contact between the planar structure 115 and the mounting body 10 is stable.

[0073] like Figure 8 and 9 As shown, the aforementioned fastener 112 includes a first connector 118 and a second connector 117. The first connector 118 is fixedly connected to one end of the connector 110, and the second connector 117 is fixedly connected to the other end of the connector 110. The first connector 118 and the second connector 117 are inserted to connect the two ends of the connector 110 together, forming a ring-shaped connector 110 so that the connector 110 can be fitted onto the mounting body 10. When the connector 110 is installed on the mounting body 10, the connector 110 surrounds the outer surface of the mounting body 10. By inserting the first connector 118 and the second connector 117, the two ends of the connector 110 are connected together, and the connector 110 is fitted onto the mounting body 10.

[0074] The first connector 118 has a connector hole, which is coaxially arranged with the first connector 118 and is formed by an inward recess from the end face of the first connector 118 that is not connected to the connector 110. The depth of the connector hole is adapted to the length of the second connector 117. A locking block 119 is provided in the connector hole, which is arranged along the radial direction of the connector hole and protrudes from the inner sidewall of the connector hole. The second connector 117 has a cylindrical structure and a locking groove 120, which is arranged along the radial direction of the second connector 117. The groove structure 120 is formed by the inward indentation of the outer peripheral side of the second connector 117. When the second connector 117 is inserted into the insertion hole of the first connector 118, the groove 120 and the locking block 119 are positioned opposite each other, and the locking block 119 is inserted into the groove 120, thereby connecting the first connector 118 and the second connector 117. When the first connector 118 and the second connector 117 are subjected to axial tension, the locking block 119 restricts the axial relative movement of the first connector 118 and the second connector 117 against the groove 120, preventing the two ends of the connector 110 from loosening. The surface where the groove 120 and the locking block 119 meet is set with an incline so that the groove 120 and the locking block 119 can engage and cooperate. A first through hole 121 and a second through hole 122 are provided on the first connector 118. The first through hole 121 and the second through hole 122 are located on a set of oppositely arranged side surfaces of the first connector 118. The first through hole 121 is close to the end of the first connector 118 that is connected to the connector 110, and the second through hole 122 is close to the free end of the first connector 118. The second through hole 122 corresponds to the position of the locking block 119, providing space for the second connector 117 to deform when it comes into contact with the locking block 119 during the insertion of the connector. The first through hole 121 corresponds to the free end of the second connector 117, providing space for the free end of the second connector 117 to deform, which facilitates the insertion and connection of the first connector 118 and the second connector 117.

[0075] To reduce the weight of the lantern, the aforementioned connector 110, connector 111, and fastener 112 are all made of plastic.

[0076] like Figure 3-5As shown, to facilitate the installation of the connector 110 and multiple connector seats 111, the peripheral side of the mounting body 10 is provided with a circumferential receiving groove 100 and multiple axial receiving grooves 101. The circumferential receiving groove 100 is arranged along the circumferential direction of the mounting body 10 to accommodate the connector 110. The axial receiving grooves 101 are arranged along the axial direction of the mounting body 10, and each axial receiving groove 101 is connected to the circumferential receiving groove 100. The multiple axial receiving grooves 101 are arranged sequentially along the circumferential direction of the mounting body 10 to accommodate the connector seats 111. Each axial receiving groove 101 is provided with one connector seat 111, and the number of axial receiving grooves 101 is consistent with the number of connector seats 111.

[0077] The mounting body 10 is a plate-like structure with a certain thickness. Its cross-sectional shape can be circular, elliptical, square, or other shapes, depending on the actual needs. No specific requirements are specified here. In some feasible embodiments, preferably, the cross-sectional shape of the mounting body 10 is circular, so that the connecting piece 110 is evenly stressed when installed on the mounting body 10, resulting in a long service life. To reduce the weight of the lantern, the mounting body 10 is provided with multiple weight-reducing holes or grooves, which are arranged along the circumferential direction of the mounting body 10. A through hole is provided in the middle part of the mounting body 10, and the through hole is coaxially arranged with the mounting body 10.

[0078] The aforementioned circumferential receiving groove 100 is provided on the outer peripheral side of the mounting body 10, and is formed by the inward indentation of the outer peripheral side of the mounting body 10. The circumferential receiving groove 100 is a groove structure, and the circumferential receiving groove 100 is arranged along the circumferential direction of the mounting body 10 to form an annular groove structure. The depth of the circumferential receiving groove 100 is selected according to the radial dimension of the connector 110. The depth of the circumferential receiving groove 100 is greater than the radial dimension of the connector 110, so that the connector 110 is completely located in the circumferential receiving groove 100 and will not detach from the circumferential receiving groove 100 during the rotation of the connector 110.

[0079] The aforementioned axial receiving groove 101 is provided on the outer peripheral side of the mounting body 10, and is formed by the inward indentation of the outer peripheral side of the mounting body 10. The axial receiving groove 101 is a groove structure, which is a strip-shaped groove structure to facilitate the accommodation of the connecting seat 111. The axial receiving groove 101 is arranged along the axial direction of the mounting body 10, that is, the axial receiving groove 101 is perpendicularly intersecting the circumferential receiving groove 100. The two ends of the axial receiving groove 101 are respectively located on both sides of the circumferential receiving groove 100, and the intersection of the axial receiving groove 101 and the circumferential receiving groove 100 is connected. The depth of the axial receiving groove 101 is selected according to the radial dimension of the connecting seat 111. The depth of the axial receiving groove 101 is not less than the radial dimension of the connecting seat 111, so that the connecting seat 111 can be completely located in the axial receiving groove 101, so that the mounting seat 1 has a compact structure and also facilitates the setting of paper or gauze on the outside of the lantern frame. The axial receiving groove 101 is in communication with the outer peripheral side of the mounting body 10, so that the axial receiving groove 101 is connected to the outside of the mounting body 10, and the connecting seat 111 can rotate in the direction of the outside of the mounting body 10, rotating between the first state and the second state.

[0080] The axial receiving groove 101 is connected to an axial end face of the mounting body 10. Along the axial direction of the mounting body 10, the axial receiving groove 101 is connected to the axial exterior of the mounting body 10 so that the connecting seat 111 is located inside the axial receiving groove 101. One end of the connecting seat 111 with the mounting hole 113 extends out of the axial receiving groove 101. The curved transition structure 116 at the other axial end of the connecting seat 111 is located inside the axial receiving groove 101. The curved transition structure 116 can contact the axial sidewall 102 of the axial receiving groove 101. When the connecting seat 111 rotates, the curved transition structure 116 is always in contact with the axial sidewall 102 of the axial receiving groove 101. When rotating relative to the axial sidewall 102, the curved transition structure 116 contacts the axial sidewall. After 102 is disengaged, the curved transition structure 116 contacts the bottom wall 103 of the axial receiving groove 101. When the connecting seat 111 is in the second state, the planar structure 115 on the side of the connecting seat 111 contacts the axial side wall 102 of the axial receiving groove 101. The axial side wall 102 supports the connecting seat 111, and the curved transition structure 116 contacts the bottom wall 103 of the axial receiving groove 101. Alternatively, the curved transition structure 116 may not contact the axial side wall 102 of the axial receiving groove 101. During the rotation of the connecting seat 111, the curved transition structure 116 does not contact the axial side wall 102 of the axial receiving groove 101, but as the connecting seat 111 rotates, the curved transition structure 116 contacts the bottom wall 103 of the axial receiving groove 101. The distance between the two circumferential side walls of the axial receiving groove 101 is greater than the radial dimension of the connecting seat 111, so that there is a gap between the connecting seat 111 and the two circumferential side walls of the axial receiving groove 101, which will not cause obstruction during the rotation of the connecting seat 111.

[0081] When the connecting seat 111 is located in the axial receiving groove 101, the limiting member 114 contacts the bottom wall 103 of the axial receiving groove 101, limiting the distance between the side wall of the connecting seat 111 and the bottom wall 103 of the axial receiving groove 101.

[0082] In some feasible embodiments, preferably, the connector 110, the connector 111 and the fixing member 112 are integrally formed, so that the connecting assembly 11 has a stable structure, a long service life, a simple structure and is easy to assemble.

[0083] A lantern frame structure includes multiple keels 2 and lantern mounting bases 1 as described above. Each end of the keel 2 is provided with a lantern mounting base 1, and each keel 2 is connected to a lantern mounting base 1. The multiple keels 2 are arranged sequentially along the circumference of the lantern mounting base 1. Each end of each keel 2 is connected to a corresponding set of connecting seats 111 of two mounting bases 1. The structure formed by the multiple keels 2 is coaxially arranged with the mounting base 1, and the two mounting bases 1 are coaxially arranged to form a lantern frame structure.

[0084] When the lantern frame structure is in the closed state, the connecting seat 111 is in the first state. The limiting member 114 on the connecting seat 111 contacts the bottom wall 103 of the axial receiving groove 101. The connecting member 110 is located in the circumferential receiving groove 100. The end of the connecting seat 111 with the mounting hole 113 protrudes from an axial end face of the mounting body 10. The curved transition structure 116 is located in the part of the space of the axial receiving groove 101 located below the circumferential receiving groove 100. The curved transition structure 116 can contact the axial side wall 102 of the axial receiving groove 101 or not, depending on the actual needs.

[0085] An axial force is applied to any one of the mounting seats 1, causing the two mounting seats 1 to approach each other. The keel 2 bends under this force, opening the lantern frame structure. During this approach, the connecting seat 111 is subjected to the bending force of the keel 2, causing it to rotate outwards from the axial receiving groove 101. Each connecting seat 111 rotates around the connecting member 110, which rotates within the circumferential receiving groove 100. The connecting seat 111 rotates from the first state to the second state, and the limiting member 114 moves away from the bottom wall 103 of the axial receiving groove 101, resulting in a curved transition structure. The structure 116 rotates toward the bottom wall 103 of the axial receiving groove 101. When the curved transition structure 116 contacts the bottom wall 103 of the axial receiving groove 101, it slides along the length of the bottom wall 103. During this process, the planar structure 115 moves closer to the axial side wall 102 of the axial receiving groove 101 until the connecting seat 111 is in the second state. The planar structure 115 contacts the axial side wall 102 of the axial receiving groove 101. The axial side wall 102 limits the rotation of the connecting seat 111. The connecting seat 111 no longer rotates, and the lantern frame structure is in the open state.

[0086] Further optimize the plan, such as Figure 11-19As shown, the lantern frame structure also includes a first central tube 3, a second central tube 4, and a positioning device 5. The first central tube 3 is connected to one mounting base 1, and the second central tube 4 is connected to another mounting base 1. The first central tube 3 and the second central tube 4 are inserted into each other and can slide relative to each other. The arrangement of the first central tube 3 and the second central tube 4 connects the two mounting bases 1 at both ends of the keel together, forming the overall structure of the lantern frame. The first central tube 3 and the second central tube 4 are coaxially arranged. Through the relative sliding between the first central tube 3 and the second central tube 4, the two mounting bases 1 can move along the axial direction of the first central tube 3, moving relatively closer or relatively farther apart. The positioning device 5 is located on the mounting base 1 connected to the first central tube 3, and the positioning device 5 is connected to the second central tube 4. The middle tube 4 is connected, and the relative position between the first middle tube 3 and the second middle tube 4 is positioned by the positioning device 5, so that the lantern frame structure can switch between a closed state and an open state. When the second middle tube 4 is relatively close to the first middle tube 3, the lantern frame structure opens. When the lantern frame structure is in the open state, the positioning device 5 is activated to lock the second middle tube 4 and fix the second middle tube 4 in this position. The first middle tube 3 and the second middle tube 4 do not move relative to each other, so that the lantern frame structure remains in the open state. When the lantern frame structure needs to be closed, the positioning device 5 is activated to release the lock on the second middle tube 4. The second middle tube 4 and the first middle tube 3 can move relative to each other. The second middle tube 4 moves relatively away from the first middle tube 3, and the lantern frame structure closes.

[0087] Specifically, such as Figure 11-20 As shown, both the first central tube 3 and the second central tube 4 are tubular structures, with both ends of the first central tube 3 and the second central tube 4 open and not closed, allowing them to communicate with the outside world. This facilitates the insertion and connection of the first central tube 3 and the second central tube 4, and also facilitates their connection to the positioning device 5. The cross-sectional shape of the first central tube 3 and the second central tube 4 can be adapted to each other; they can both be circular, both square, or other shapes, depending on actual needs. No specific requirements are specified here.

[0088] The mounting body 10 of the aforementioned mounting base 1 has a mounting through hole 13, which is coaxially arranged with the mounting body 10. The mounting through hole 13 is a through hole that passes through the end faces of both ends of the mounting body 10 along the axial direction, forming a mounting channel structure so that the first middle tube 3 and the second middle tube 4 can be connected to the corresponding mounting base 1 respectively. One end of the first middle tube 3 is connected to a mounting base 1, and the end of the first middle tube 3 is inserted into the mounting through hole 13 of the mounting base 1. The end of the first middle tube 3 can be interference-fitted with the mounting through hole 13, or the end of the first middle tube 3 can be fixedly connected to the mounting base 1 by bolts or other connecting parts, or the end of the first middle tube 3 can be threaded to the mounting through hole 13, or other fixed connection methods can be selected according to actual needs. No specific requirements are made here. The other end of the first middle tube 3 is inserted into one end of the second middle tube 4. The inner diameter of the first middle tube 3 is compatible with the outer diameter of the second middle tube 4, with a clearance fit, so that one end of the second middle tube 4 can be inserted into the first middle tube 3, thus achieving the insertion connection between the second middle tube 4 and the first middle tube 3. The second middle tube 4 moves along the axial direction of the first middle tube 3. The other end of the second middle tube 4 is connected to another mounting base 1. The other end of the second middle tube 4 is interference-fitted with the mounting through hole 13 of the other mounting base 1. Alternatively, the other end of the second middle tube 4 is fixedly connected to the mounting through hole 13 of the other mounting base 1 by bolts or other connecting parts, or by threaded connection, or other fixed connection methods, depending on actual needs. No specific requirements are specified here.

[0089] To axially limit the other end of the second middle tube 4, a limiting cap is fixedly provided on the other mounting base 1. The limiting cap is coaxially arranged with the mounting through hole 13 of the other mounting base 1, and is located on the side of the other mounting base 1 away from the first middle tube 3. The limiting cap is a shell structure with one open end, and the limiting cap is fixedly connected to the mounting through hole 13 of the other mounting base 1 through the open end. The other end of the second middle tube 4 is located in the internal space of the limiting cap, thus limiting the axial movement of the second middle tube 4. The limiting cap can be fixedly connected to the second middle tube 4 by bolts or other connecting parts, or it can be plugged in without a fixed connection. Preferably, the limiting cap and the mounting base 1 are integrally molded, which ensures structural stability and long service life.

[0090] like Figure 12-23As shown, the positioning device 5 includes a snap-fit ​​member 50, a receiving member 54 connected to the snap-fit ​​member 50, an abutment member 51 disposed on the receiving member 54, a positioning member 52 disposed on the mounting base 1, and an end cap 53. The snap-fit ​​member 50 is connected to the second middle tube 4. The abutment member 51 can slide relative to the receiving member 54. The end cap 53 is disposed on the mounting base 1, and the end cap 53 and the mounting base 1 form an accommodating space. The positioning member 52 is disposed in the accommodating space and is disposed on both sides of the receiving member 54. The positioning member 52 can move relative to the mounting base 1 along the radial direction of the receiving member 54, extend out of the accommodating space, and abut against the receiving member 54, so that the lantern frame structure is in the open state. When the abutment member 51 contacts and engages with the positioning member 52, the positioning member 52 moves into the accommodating space, and the lantern frame structure closes. Through the cooperation between the receiving member 54 and the positioning member 52, and the cooperation between the abutment member 51 and the positioning member 52, the opening and closing of the lantern frame structure are realized.

[0091] like Figure 13 , 15 As shown in 18, 19, and 21, the aforementioned snap-fit ​​component 50 includes a fixed part 501 and a plug-in part 500 arranged coaxially. The plug-in part 500 is located on one side of the fixed part 501 and is fixedly connected to the fixed part 501. This fixed connection method is preferably integrally formed, which makes the snap-fit ​​component 50 structurally stable and has a long service life. The insertion part 500 is a cylindrical structure with a through hole. The through hole is coaxially arranged with the insertion part 500. The through hole facilitates the connection between the snap-fit ​​part 50 and the receiving part 54. The receiving part 54 is inserted into the snap-fit ​​part 50, with a portion of the receiving part 54 located within the through hole. The outer diameter of the insertion part 500 is adapted to the inner diameter of the second middle tube 4, so that the insertion part 500 and the second middle tube 4 are fixedly connected. This fixed connection can be through a threaded connection, an interference fit, or other fixed connection methods, selected according to actual needs. The fixing part 501 is a cylindrical structure. The outer diameter of the fixing part 501 is larger than the outer diameter of the insertion part 500. The outer diameter of the fixing part 501 is coaxially arranged with the second middle tube 4. The outer diameter of the fixing part 501 is adapted to the inner diameter of the first middle tube 3. The fixing part 501 is clearance-fitted with the first middle tube 3, so that the fixing part 501 can slide relative to the first middle tube 3. The side of the fixing part 501 facing the insertion part 500 contacts the free end of the second middle tube 4 to position the installation of the snap-fit ​​member 50. The insertion part 500 is inserted into the second middle tube 4, and the fixing part 501 is located outside the second middle tube 4 to limit the insertion depth of the insertion part 500. The insertion part 500 is fixedly connected to the second middle tube 4, so that the snap-fit ​​member 50 moves with the movement of the second middle tube 4, thereby causing the receiving member 54 and the abutment member 51 to move simultaneously.

[0092] The fixing part 501 is provided for connection with the receiving part 54. A limiting part 502 is fixedly provided on the side of the fixing part 501 away from the insertion part 500. The limiting part 502 is a column structure. The limiting part 502 is coaxially arranged with the fixing part 501, and the outer diameter of the limiting part 502 is smaller than the outer diameter of the fixing part 501. Therefore, the outer diameter of the limiting part 502 is smaller than the inner diameter of the first middle tube 3, so that there is a gap between the outer wall of the limiting part 502 and the inner wall of the first middle tube 3, so as to facilitate the installation of the abutment 51. The limiting part 502 limits the movement of the abutment 51, so that the abutment 51 slides on the receiving part 54 and slides on the receiving part 54.

[0093] The limiting part 502 has a through hole, which is coaxially arranged with the limiting part 502. The fixing part 501 has a through hole, which is coaxially arranged with the fixing part 501. The through hole of the fixing part 501 is coaxially arranged and connected with the through hole of the limiting part 502. The through hole of the fixing part 501 is coaxially arranged and connected with the through hole of the insertion part 500. The diameter of the through hole of the fixing part 501 is smaller than the diameter of the through hole of the insertion part 500, so that one end of the receiving member 54 passes through the through hole of the limiting part 502 and the through hole of the fixing part 501 and enters the through hole of the insertion part 500. The receiving member 54 is engaged with the fixing part 501, connecting the receiving member 54 and the engaging member 50 together. The receiving member 54 and the engaging member 50 move simultaneously with the second middle tube 4.

[0094] The aforementioned fixing part 501 is fixedly connected to the limiting part 502, and the limiting part 502 is fixedly connected to the insertion part 500. This fixed connection method is preferably integrally formed, which has a stable structure and a long service life.

[0095] like Figure 21 , 22 As shown, the aforementioned receiving member 54 includes a receiving portion 540, a connecting portion 541, and a snap-fit ​​portion 543 coaxially arranged. The diameter of the receiving portion 540 is larger than the diameter of the connecting portion 541. The abutment member 51 is fitted onto the connecting portion 541, and the snap-fit ​​portion 543 snaps into the snap-fit ​​member 540. The abutment member 51 can move within the axial length range of the connecting portion 541. One end of the receiving portion 540 is fixedly connected to the connecting portion 541, and the other end of the connecting portion 541 is fixedly connected to the snap-fit ​​portion 543. This fixed connection method is preferably integrally molded, resulting in a stable structure and a long service life.

[0096] The snap-fit ​​part 543 is a cylindrical structure. The outer diameter of the snap-fit ​​part 543 is smaller than the outer diameter of the connecting part 541. The outer diameter of the snap-fit ​​part 543 is adapted to the diameter of the through hole of the limiting part 502. Two protrusions 542 are provided on the peripheral sidewall of the snap-fit ​​part 543. The two protrusions 542 are symmetrically arranged. A groove structure is formed between the protrusions 542 and the end of the connecting part 541 that connects to the snap-fit ​​part 543. The limiting part 502 and the fixing part 501 of the snap-fit ​​member 50 are inserted into the groove structure to realize the snap-fit ​​connection between the snap-fit ​​member 50 and the receiving member 54, connecting the snap-fit ​​member 50 and the receiving member 54 together. The snap-fit ​​member 50 and the receiving member 54 are both made of plastic. The snap-fit ​​part 543 moves in and out of the insertion part through elastic deformation to realize the insertion of the snap-fit ​​part 543 and the snap-fit ​​member 50.

[0097] The connecting part 541 is a cylindrical structure. The outer diameter of the connecting part 541 is larger than the outer diameter of the snap-fit ​​part 543. The outer diameter of the connecting part 541 is larger than the diameter of the through hole of the limiting part 502. The end of the connecting part 541 that is connected to the snap-fit ​​part 543 contacts the free end of the limiting part 502 to limit the installation of the receiving part 54 and the snap-fit ​​part 50. The outer diameter of the limiting part 502 is larger than the outer diameter of the connecting part 541 so that the limiting part 502 limits the movement stroke of the abutment part 51.

[0098] The receiving part 540 is a cylindrical structure, and its outer diameter is larger than that of the connecting part 541, resulting in a stepped structure between the receiving part 540 and the connecting part 541. This stepped structure cooperates with the positioning member 52, which abuts against the stepped structure to limit the movement of the receiving part 54. The outer peripheral side of the receiving part 540 is a sloped structure to allow for sliding contact between the receiving part 540 and the positioning member 52.

[0099] The outer diameter of one end of the aforementioned abutment 51 is larger than the outer diameter of the other end. The outer diameter of the larger diameter end of the abutment 51 is adapted to the outer diameter of the receiving portion 540, and the outer diameter of the smaller diameter end of the abutment 51 is smaller than the outer diameter of the limiting portion 502. Specifically, the abutment 51 has a ring-shaped structure and a certain length. The length of the abutment 51 is less than the length of the connecting portion 541 so that the abutment 51 can move on the connecting portion 541 along the axial direction of the connecting portion 541. The inner circumferential side of the abutment 51 has a uniform diameter structure, and the diameter of the inner circumferential side of the abutment 51 is adapted to the diameter of the outer circumferential side of the connecting portion 541. The inner circumferential side of the abutment 51 and the outer circumferential side of the connecting portion 541 are in clearance fit. The outer circumferential side of the abutment 51 is... The variable diameter structure has a diameter that gradually increases or decreases along the axial direction from one end of the abutment 51 to the other end. That is, the outer circumference of the abutment 51 is a conical surface. The large diameter end of the abutment 51 corresponds to the receiving part 540 so that the large diameter end of the abutment 51 can contact the stepped structure of the receiving part 540. The small diameter end of the abutment 51 corresponds to the limiting part 502 and contacts the end of the limiting part 502. The distance between the stepped structure of the receiving part 540 and the end of the limiting part 502 is the travel distance of the abutment 51. The abutment 51 moves between the stepped structure of the receiving part 540 and the end of the limiting part 502.

[0100] like Figure 13 , 15 As shown in Figures 18, 19, 21, and 23, the aforementioned positioning member 52 is provided with an elastic member 55, so that the positioning member 52 can be reset under the action of the elastic member 55. A mounting groove 14 is provided at the top of the mounting body 10. The mounting groove 14 is formed by an inward indentation from the upper surface of the top of the mounting body 10. The mounting groove 14 is connected to the outside of the top of the mounting body 10. The mounting groove 14 is arranged along the radial direction of the mounting body 10, and one end of the mounting groove 14 is connected to the mounting through hole 13. A blocking part 15 is provided at one end near the mounting through hole 13. The blocking part 15 is arranged along the axial direction of the mounting through hole 13. One end of the blocking part 15 is fixedly connected to the bottom wall of the mounting groove 14. The length of the blocking part 15 along the axial direction of the mounting through hole 13 is less than the depth of the mounting groove 14, so that the part of the mounting groove 14 that is not blocked by the blocking part 15 communicates with the mounting through hole 13. The blocking part 15 restricts the movement of the positioning member 52 located in the mounting groove 14, so that the positioning member 52 can only move in the radial direction of the mounting body 10 within the mounting groove 14.

[0101] The aforementioned positioning element 52 includes a positioning body 520 and an abutment portion 521 connected to the positioning body 520. The abutment portion 521 is disposed at one end of the positioning body 520. Both the positioning body 520 and the abutment portion 521 are block structures. The cross-sectional shape of the positioning body 520 is adapted to the cross-sectional shape of the mounting groove 14, and the axial dimension of the positioning body 520 along the mounting through hole 13 is adapted to the depth of the mounting groove 14. The positioning body 520 is located in the mounting groove 14 and can move within the positioning groove. The abutment portion 521 is disposed at the end of the positioning body 520 facing the mounting through hole 13. The abutment portion 521 is located along the axis of the mounting through hole 13. The abutment 521 has a large-diameter end and a small-diameter end. The large-diameter end of the abutment 521 is flush with the side of the positioning body 520 that does not contact the bottom of the mounting groove 14 and is located on the same plane. The dimension of the abutment 521 along the axial direction of the mounting through hole 13 is smaller than the dimension of the positioning body 520 in that direction. The distance from the small-diameter end of the abutment 521 to the bottom wall of the mounting groove 14 is not less than the length of the blocking part 15. The side of the abutment 521 facing the mounting through hole 13 is inclined from the small-diameter end to the large-diameter end so that the abutment 521 abuts and cooperates with the abutment member 51. At the same time, the large-diameter end of the abutment 521 cooperates with the stepped structure of the receiving part 540.

[0102] The elastic element 55 is disposed in the mounting groove 14. One end of the elastic element 55 is connected to the inner side wall of the mounting groove 14 facing the blocking member, and the other end of the elastic element 55 is inserted into the positioning member 52. When the elastic element 55 is in a compressed state, the positioning member 52 can be moved under the action of the restoring force of the elastic element 55.

[0103] The number of positioning elements 52 is consistent with the number of mounting slots 14. The positioning elements 52 are symmetrically arranged on both radial sides of the receiving element 54 to position the receiving element 54 from two opposite radial directions.

[0104] The end cap 53 is fastened to the mounting body 10. The end cap 53 has a through hole. The through hole of the end cap 53 is coaxially arranged with the end cap 53. The through hole of the end cap 53 is coaxially arranged with the mounting through hole 13 of the mounting body 10. That is, the end cap 53 is an annular plate structure that covers the mounting groove 14. The end cap 53 and the mounting groove 14 form a receiving space. The positioning member 52 can be located in the receiving space. The end cap 53 limits the movement of the positioning member 52 along the axial direction of the mounting body 10. The abutment part 521 can move to the outside of the receiving space along the radial direction of the mounting body 10.

[0105] The elastic element 55 mentioned above is preferably a spring.

[0106] In some feasible embodiments, the second central tube 4, the snap-fit ​​member 50, the receiving member 54, the end cap 53 and the abutment member 51 are coaxially arranged, and the second central tube 4 is coaxially arranged with the mounting body 10.

[0107] When the lantern frame structure is opened, a force is applied to the mounting base 1 connected to the second central tube 4, causing the mounting base 1 to move towards another mounting base 1. The second central tube 4 moves along with the mounting base 1, and the end of the second central tube 4 with the snap-fit ​​member 50 moves within the first central tube 3. As the second central tube 4 moves, the receiving portion 540 of the receiving member 54 first contacts the positioning member 52, and the top end of the receiving portion 540 contacts the inclined surface of the abutment portion 521. As the receiving member 54 moves, the peripheral side of the receiving portion 540 contacts the inclined surface of the abutment portion 521, and a force is applied to the positioning member 52 along the radial direction of the mounting body, pushing the positioning member 52 to move along the mounting groove 14 and compressing the elastic member 55. During the movement of the receiving member 54, the peripheral side of the receiving portion 540 remains in contact with the inclined surface of the abutment portion 521. When the inclined surface of the abutment part 521 separates from the receiving part 540, since the diameter of the receiving part 540 is larger than the diameter of the connecting part 541, the positioning member 52 moves outward from the mounting groove 14 under the restoring force of the elastic member 55. The limiting part 502 contacts the connecting part 541. As the second middle tube 4 continues to move, the connecting part 541 slides relative to the limiting part 502, stopping the pressure applied to the mounting seat 1 connected to the second middle tube 4. At this time, the lantern frame structure is in the open state, each keel is in the bent state, and the two mounting seats 1 move in opposite directions under the restoring force of the keel. The receiving part 540 is blocked by the positioning member 52, and the side of the abutment part 521 facing the end cover 53 contacts the stepped structure of the receiving part 540, restricting the directional movement of the receiving member 54 and keeping the lantern frame structure in the open state.

[0108] When the lantern frame structure needs to be folded, pressure is applied to the mounting base 1 connected to the second central tube 4. The positioning member 52 contacts the abutment member 51, and the abutment member 51 contacts the inclined surface of the positioning member 52. A force is applied to the positioning member 52 in the radial direction of the mounting body 10. The positioning member 52 moves along the mounting groove 14, compressing the elastic member 55. Under the action of gravity, the abutment member 51 moves towards the receiving part 540, and the large-diameter end of the abutment member 51 contacts the stepped structure of the receiving part 540. Release the force applied to the mounting base 1 connected to the second central tube 4. Under the action of the keel's restoring force, the two mounting bases 1 move in opposite directions. The receiving part 54 moves with the second central tube 4. When the abutting part 51 disengages from the positioning part 52, the positioning part 52 contacts the receiving part 540. As the receiving part 54 moves, the receiving part 540 disengages from the positioning part 52. The second central tube 4 moves carrying the snap-fit ​​part 50, the receiving part 54, and the abutting part 51, thereby realizing the folding of the lantern frame structure.

[0109] Due to the adoption of the above technical solution, the lantern mounting base has a simple structure, consisting of a connecting component and a mounting body. The connecting component is mounted on the mounting body and can rotate relative to the mounting body. The connecting component is an integral structure with mounting holes for mounting the keel. Assembly of the mounting base and keel is completed simply by connecting the keel to the connecting component. Assembly and use are convenient, and it is not easily damaged. The integral structure of the connecting component ensures a long service life. The mounting body is provided with circumferential receiving grooves and multiple axial receiving grooves to accommodate the connectors and connecting seats of the connecting component, ensuring that the connectors and connecting seats remain on the mounting body during rotation and will not detach from the mounting body, thus guaranteeing the structural stability of the lantern frame structure during opening and closing. The multiple connecting seats can connect multiple keels together, forming an integral structure of the lantern frame with the mounting base. Limiting components are provided on the connecting seats to limit the distance between the connecting seat and the mounting body, and also to position the installation of the connecting seats, providing sufficient space for the rotation of the connecting seats to ensure stability. The connecting seat can rotate on the mounting body, allowing it to switch positions between a first and a second state. The curved transition structure ensures that the connecting seat makes line or point contact with the bottom wall of the axial receiving groove during rotation, reducing resistance. The planar structure ensures that when the connecting seat is in the second state, the planar structure makes surface contact with the axial sidewall of the axial receiving groove, allowing the axial sidewall to support the connecting seat and maintain the stability of the lantern frame structure. The positioning device, the first central tube, and the second central tube are included. The positioning device can lock the positions of the first and second central tubes to keep the lantern frame structure open, and it can also unlock the positions of the first and second central tubes to close the lantern frame structure. The positioning device has a receiving part, an abutting part, and a positioning part. The cooperation between the receiving part and the positioning part, and between the positioning part and the abutting part, enables the lantern frame structure to switch between open and closed states.
