Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship device, in particular to a multifunctional ceiling of a ship. BACKGROUND

[0002] The ceiling of a ship is one of the components of a ship, which mainly provides sunshade, rain protection and certain degree of weather protection for the deck area, so as to improve the working and living environment of the crew, and improve the comfort and safety.

[0003] In order to adapt to the use demand of the ceiling under different weather conditions, the existing technology usually adopts a sliding type ceiling structure; such ceiling is usually composed of several relatively movable parts, and the relative sliding between the parts is controlled to realize the expansion and shielding or retraction and opening; specifically, when sunshade and rain protection are needed, the ceiling parts are expanded and partially overlapped; when shielding is not needed, the parts are slid to close to open the top space.

[0004] However, such ceiling has obvious functional limitations: first, since the mutual overlap between the parts is needed to realize continuous coverage, the overlapping area cannot be opened all the time, which limits the effective adjustment range of the ceiling; and this problem is a structural inherent defect, which cannot be solved by simply increasing the number of parts, because the increase of the number of parts will only aggravate the accumulation of the overlapping area, which not only occupies more space, but also increases the complexity and potential risk of the structure. Secondly, due to the limitation of the small number of parts, the opening and closing state of the ceiling is relatively single, and the selection and adjustment of the sunshade area or the opening degree cannot be more detailed, so it is difficult to meet the high personalized demand of the user for the sunshade range and the light transmission area.

[0005] This contradiction has become more and more obvious in different use environments from inland rivers, lakes to inland seas and shallow seas, with the expansion of the operation sea area, the enhancement of ultraviolet radiation, the more frequent use of the ceiling, and the corresponding improvement of the user's requirement for the adjustment flexibility. That is, when the application scene is further extended to the field of marine engineering which requires higher, the limitation of the existing ceiling design will be more prominent. SUMMARY

DETAILED DESCRIPTION

[0074] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0075] Embodiment: a multifunctional ceiling of a ship, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 , comprising: two groups of mounting seats 11 arranged in parallel, fixedly installed on the left and right sides of the hull 01;

[0076] The support frame 12 is erected between the two mounting seats 11, and constitutes the main support framework of the ceiling, and a total of four groups are evenly arranged along the mounting seat 11;

[0077] The roll plate cylinder 13 is arranged in the installation groove 1101 of the installation base 11. Each pair of roll plate cylinders 13 between the adjacent two groups of support frames 12 is provided with two groups of roll plate cylinders 13 of sunshade type and rainproof type. The two groups of roll plate cylinders 13 are arranged in the vertical direction, and the upper and lower sequences of all positions are consistent. In the embodiment, the sunshade roll plate cylinder 13 is above, and the rainproof roll plate cylinder 13 is below, that is, there are twelve groups of six pairs of roll plate cylinders 13.

[0078] The roll plate cylinder 13 is composed of a cylinder core 1301 and a roll plate material 1302. The cylinder core 1301 is rotatably arranged in the installation groove 1101, and is provided with an elastic element capable of automatically resetting after rotation. In the embodiment, a roll spring is used, one end of which is fixed to the installation base 11, and the other end is fixed to the cylinder core 1301. The roll plate material 1302 has a flexible curling characteristic, is wound on the cylinder core 1301, and its inner end is fixed to the cylinder core 1301, so as to realize winding or unfolding with the rotation of the cylinder core 1301.

[0079] The connecting part 1304 is fixedly arranged at the outer end of the roll plate material 1302.

[0080] In the two groups of roll plate cylinders 13 of the same function between the adjacent two groups of support frames 12, one group of roll plate materials 1302 is provided with a tenon 1305 structure, and the other group of roll plate materials 1302 is provided with a mortise 1306 structure. By pulling out the roll plate materials 1302 of the two groups of roll plate cylinders 13 outward, and embedding and splicing the tenon 1305 and the mortise 1306, the seamless butt joint of the two parts of roll plate materials 1302 can be realized, and the integrity of the coverage can be ensured.

[0081] The guide groove 14 is arranged on the front and rear sides of each group of support frames 12, is used for limiting the movement track of the roll plate material 1302 during unfolding or winding, ensures the position accuracy, realizes the seamless butt joint of the roll plate material 1302 and the support frame 12, and improves the overall waterproof performance. The opening of the guide groove 14 is arranged at the bottom of the support frame 12, so that the roll plate material 1302 can be embedded in the guide groove 14 when it is unfolded upward from the bottom.

[0082] The winding and unfolding assembly is arranged in each group of support frames 12, and is used for controlling the unfolding or winding of the roll plate material 1302.

[0083] The magnetic attraction surface 1103 is arranged on the installation base 11, can be magnetically attracted and matched with the connecting part 1304, is used for fixing the outer end position of the roll plate material 1302, so that the roll plate material 1302 can keep a stable winding state.

[0084] When the function of the ceiling needs to be personalized, for example, the function between the support frames 12 is switched to the sunshade function:

[0085] The sunshade roller plate 1302 is unlocked by controlling the connection part 1304 of the sunshade roller 13 in the range of the support frame 12 to overcome the magnetic attraction force of the magnetic surface 1103, and then the sunshade roller plate 1302 is pulled out to the guide groove 14 from the opening at the bottom of the support frame 12, so that the sunshade roller plate 1302 is displaced upward along the guide groove 14 until the connection part 1304 of the sunshade roller plate 1302 on both sides is moved to the middle position of the top of the support frame 12. The connection part 1304 of the sunshade roller plate 1302 on both sides is seamlessly connected by embedding the tenon 1305 structure and the mortise 1306 structure, and the position of the sunshade roller plate 1302 is locked by closing the folding and unfolding assembly, so that the range of the support frame 12 is switched to the sunshade function.

[0086] When the canopy is switched to the rain shelter function:

[0087] The sunshade roller plate 1302 is driven by the folding and unfolding assembly to be retracted to the mounting seat 11, and under the reset force of the elastic member in the cylinder core 1301, the sunshade roller plate 1302 is automatically and neatly retracted into the mounting groove 1101, and the folding and unfolding assembly controls the rain shelter roller 13 in the range to be unfolded, so that the canopy is switched to the rain shelter function.

[0088] Compared with the sunshade roller plate 1302, the rain shelter roller plate 1302 has good lighting performance, can ensure the natural brightness in the covered area of the canopy, does not need to use a large number of lighting devices, effectively reduces energy waste, and can be retracted in the mounting seat 11 in a compact form, greatly reduces the space occupation, and the structure of the sunshade roller plate 1302 is not easy to deform, can maintain stable canopy shape after being unfolded, has strong structural stability and high reliability.

[0089] Referring to Figure 2 , Figure 4 and Figure 5 , four groups of folding and unfolding assemblies are arranged between the two adjacent groups of support frames 12, that is, twelve groups of folding and unfolding assemblies are arranged, and the two groups of folding and unfolding assemblies on the same side in the corresponding range of the two adjacent groups of support frames 12 work cooperatively to realize the folding and unfolding operation of the sunshade roller plate 1302 in the corresponding range, and each group of folding and unfolding assemblies comprises:

[0090] The electronic push rod 15 is slidably installed on the support frame 12 and is displaced along the contour of the support frame 12, and the displacement stroke occupies half of the length of the contour of the support frame 12;

[0091] The docking shaft 1501 is assembled at the rod end of the electronic push rod 15, and its displacement is controlled by the telescopic control of the electronic push rod 15; the docking hole 1303 corresponding to the docking shaft 1501 is arranged on the connecting part 1304 of the coiled plate material 1302, when it is necessary to connect the coiled plate material 1302, the electronic push rod 15 controls the docking shaft 1501 to extend and penetrate into the docking hole 1303, so that stable connection between the folding and unfolding assembly and the coiled plate material 1302 is established;

[0092] The two first sprockets 16 are rotatably installed in the support frame 12;

[0093] The first chain 17 is arranged between the two first sprockets 16 and is engaged with the first sprockets 16, the rotation of the first sprockets 16 realizes the rotation of the first chain 17, and the first chain 17 is fixed with the electronic push rod 15;

[0094] The first motor 18 is fixedly installed at the top of the support frame 12, and its output end is in transmission connection with one of the first sprockets 16, and in the embodiment, a transmission belt set 1801 is adopted to realize the transmission;

[0095] The guide surface 1102 is arranged on the mounting seat 11, and is used for guiding and adjusting the position of the outer end of the coiled plate material 1302, so that the positions of the connecting parts 1304 of the two groups of coiled plate materials 1302 are staggered to avoid mutual interference, and the docking shaft 1501 is more smoothly matched with the docking hole 1303 of the target coiled plate material 1302.

[0096] When the folding and unfolding assembly is controlled to unfold the coiled plate material 1302, the electronic push rod 15 of the folding and unfolding assembly is started, the docking shaft 1501 at the rod end is controlled to extend and is inserted into the docking hole 1303 on the target coiled plate material 1302; then, the first motor 18 is started, the first sprocket 16 is rotated to drive the first chain 17 to rotate circularly, the electronic push rod 15 is driven to displace along the track, and the coiled plate material 1302 is pulled to be unfolded synchronously; when the folding and unfolding assembly is controlled to wind the coiled plate material 1302, the first motor 18 is started and is controlled to rotate reversely, so that the coiled plate material 1302 is pulled to be collected to the mounting seat 11;

[0097] When the folding and unfolding assembly is used to switch the connection of different functional coiled plate materials 1302, the electronic push rod 15 is controlled to retract, the docking shaft 1501 is withdrawn from the docking hole 1303 of the currently connected coiled plate material 1302; then, the electronic push rod 15 is controlled to move to the corresponding connecting position of another functional coiled plate material 1302, the electronic push rod 15 is started again, the docking shaft 1501 is controlled to extend and is inserted into the docking hole 1303 of the new target coiled plate material 1302, and the connection switching is completed.

[0098] The transmission path of the retracting assembly is used, power transmission is uninterrupted and loss is small, the retracting process of the rolled plate 1302 is stable, and the functions of the rolled plate 1302 are switched conveniently, without complex mechanical adjustment, so that the efficiency and convenience of the function switching of the roof are greatly improved.

[0099] Referring to Figure 2 、 Figure 7 、 Figure 8 The roof further comprises guide rails 1104 fixedly installed on the mounting seats 11 on the two sides, and the support frames 12 are slidably installed on the mounting seats 11 through the guide rails 1104.

[0100] The moving wheels 21 are rotatably installed at the bottoms of the groups of support frames 12, so that the sliding contact between the support frames 12 and the guide rails 1104 is converted into rolling contact, the frictional resistance is greatly reduced, and smooth displacement of the support frames 12 is realized.

[0101] All the support frames 12 are divided into three types, the front frame bodies 1201 located at the frontmost sides of all the support frames 12 and serving as main moving ends, the rear frame bodies 1202 located at the rearmost sides of all the support frames 12 and serving as integral displacement references to avoid integral position deviation, and the intermediate frame bodies 1203 between the front frame bodies 1201 and the rear frame bodies 1202.

[0102] The moving assemblies are arranged in the mounting seats 11 and used for driving the front frame bodies 1201 to move in the front-rear direction.

[0103] Referring to Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 A group of moving assemblies are arranged in each of the mounting seats 11 on the two sides, and the two groups of moving assemblies are synchronously operated to ensure stable displacement of the front frame bodies 1201.

[0104] The four second sprockets 22 are rotatably installed at the inner parts of the front and rear ends of the mounting seat 11.

[0105] The second chain 23 is wound between the second sprockets 22 and engaged with the second sprockets 22, the rotation of the second sprockets 22 realizes rotation of the second chain 23, and the second chain 23 is fixedly connected with the front frame bodies 1201 through the connecting plates 24.

[0106] The second motor 25 is fixedly installed in the mounting seat 11, and the output end of the second motor 25 is fixed with one of the second sprockets 22.

[0107] The ceiling further comprises connecting assemblies arranged between two adjacent groups of support frames 12 to connect all the support frames 12 into a whole, ensuring the coordination of the unfolding or folding of all the support frames 12, and avoiding the deviation of a single group of support frames 12.

[0108] and positioning assemblies arranged on the rear frame body 1202 to fix the position of the rear frame body 1202 after the rear frame body 1202 is unfolded to a preset position.

[0109] After all the rolled plates 1302 are rolled into the mounting seat 11, the second motor 25 in the mounting seat 11 is started to drive the second sprocket 22 fixed thereto to rotate, thereby driving the second chain 23 to rotate in a cycle; through the connecting effect of the connecting plate 24, the forward rotation of the second chain 23 pulls the front frame body 1201 to move forward, and the reverse rotation of the second chain 23 pulls the front frame body 1201 to move backward;

[0110] When the front frame body 1201 moves forward, the displacement force is transmitted to the support frames 12 at the rear through the connecting assemblies between the support frames 12, so as to realize the unfolding of all the support frames 12 forward; when the front frame body 1201 moves to a preset unfolding position, the position of the rear frame body 1202 is locked by the positioning assemblies, the connecting assemblies can pull the middle frame body 1203 to the corresponding position, and the precise unfolding of all the support frames 12 is realized; when the front frame body 1201 moves backward, it directly pushes all the support frames 12 at the rear to move backward through the successive contact between the support frames 12.

[0111] Therefore, the support frames 12 can be moved to above the cockpit 02 through folding, the ceiling is completely folded and displaced, the view range above the deck of the ship is no longer blocked, and an unobstructed viewing angle is provided for the user; the user does not need to go to the edge area of the ship to obtain a good view, thereby improving the safety of the ship.

[0115] a connecting head 43 rotatably installed between the ends of the two connecting rods 42 to assist the flat folding of the connecting rods 42;

[0116] And a limiting torsion spring 44 is fixedly installed between the connecting rod 42 and the connecting head 43, sleeved on the rotating shaft between the two, for limiting the rotating direction of the connecting rod 42, so that the connecting rod 42 is allowed to rotate downward only when it is in a flat state.

[0117] When the current frame body 1201 is displaced backward under the driving of the moving assembly, the distance between the two adjacent groups of support frames 12 gradually decreases, so the distance between the two mounting blocks 41 in the corresponding connecting assembly is synchronously reduced, at this time, under the action of the limiting torsion spring 44, the connecting rod 42 will rotate downward, and the two connecting rods 42 are gradually folded with the reduction of the distance between the mounting blocks 41, so that the adjacent support frames 12 will smoothly approach each other, and finally all the support frames 12 are folded; when the current frame body 1201 is displaced forward, the distance between the adjacent support frames 12 gradually increases, the distance between the two mounting blocks 41 in the connecting assembly is synchronously enlarged, the connecting rod 42 is gradually stretched with the increase of the distance between the mounting blocks 41, and the limiting torsion spring 44 is twisted under the action of the rotation of the connecting rod 42, and enters the force storage state; when the distance between the two groups of support frames 12 reaches the preset standard distance, the connecting rod 42 and the connecting head 43 are completely stretched and in a flat state; then, the connecting rod 42 in a flat state becomes a force transmission medium, and the displacement force of the front frame body 1201 is transmitted to the remaining support frames 12 through the connecting assembly in this state, and the remaining support frames 12 continue to displace until the connecting rods 42 of all the connecting assemblies are kept flat, and all the support frames 12 are unfolded in place.

[0118] Referring to Figure 9 The positioning assembly comprises a fixed block 32 which is slidingly installed on the lower part of the rear frame body 1202 and is displaced in the vertical direction;

[0119] And a limiting spring 33 which is fixedly installed between the rear frame body 1202 and the fixed block 32 and is used for applying an elastic force downward to the fixed block 32;

[0120] The limiting slot 31 is provided on the mounting seat 11 and is used for locking the position of the rear frame body 1202 in cooperation with the fixed block 32, the front side of the limiting slot 31 is a vertical surface, and the rear side is an inclined surface.

[0121] When the rear frame body 1202 moves forward along with the whole support frame 12 until the fixing block 32 is aligned with the limiting slot 31 on the mounting base 11, the limiting spring 33 pushes half of the fixing block 32 into the limiting slot 31. When the rear frame body 1202 continues to move forward slightly, the fixing block 32 finally contacts with the vertical surface on the front side of the limiting slot 31, and the vertical surface blocks the forward displacement of the fixing block 32. Therefore, the limiting effect is transmitted to the rear frame body 1202, so that the rear frame body 1202 stops moving and remains at the current position, thereby realizing the automatic positioning of the rear frame body 1202. When the support frame 12 is folded, the rear frame body 1202 is pushed to move backward, the fixing block 32 will move upward along the inclined surface on the rear side of the limiting slot 31 under the guidance of the inclined surface, and gradually disengage from the limiting slot 31. The limiting spring 33 is compressed to store energy, which is ready for the automatic positioning of the rear frame body 1202 next time. Therefore, by using the positioning assembly, the function of “automatic locking when in place and automatic unlocking under force” of the rear frame body 1202 is realized, which not only ensures the stability when unfolded, but also does not affect the smoothness of the folding operation.

[0122] Referring to Figure 10 、 Figure 11 and Figure 12 , the roof further comprises: a locking assembly arranged between two adjacent connecting assemblies, a total of four groups, for locking the flat state of the connecting rod 42, further enhancing the structural stability of the support frame 12 after unfolding, each group of locking assemblies comprising:

[0123] a locking block 45 slidably mounted on the mounting block 41, specifically on the front mounting block 41 in the rear connecting assembly of the two adjacent connecting assemblies, the locking block 45 is inserted into the connecting rod 42 connected to the mounting block 41 where the locking block 45 is located, thereby locking the connecting rod 42 and preventing unintended rotation of the connecting rod 42, and the lower part of the locking block 45 is provided with an inclined contact surface;

[0124] a control block 46 slidably mounted in the same mounting block 41 as the locking block 45, which has an extension part and penetrates out of the outside of the mounting block 41;

[0125] a flat tooth part 47 fixedly installed on the locking block 45 and the control block 46, respectively, and the directions of the flat tooth parts 47 of the two are opposite;

[0126] a gear 48 rotatably installed in the mounting block 41 where the locking block 45 and the control block 46 are located, which is synchronously meshed with the flat tooth parts 47 on the locking block 45 and the control block 46;

[0127] a reset torsional spring 49 fixedly installed between the gear 48 and the mounting block 41, and sleeved on the connecting shaft between the two;

[0128] And the control part 4101 is fixedly installed on the mounting block 41, and specifically located on the front side mounting block 41 in the front connecting assembly of the two adjacent connecting assemblies, and used for contacting with the extension part of the control block 46.

[0129] When the support frames 12 are separated from each other, the connecting rods 42 in the connecting assemblies gradually expand to a flat state, in the process, the connecting rods 42 rotate upward, the edges thereof will contact with the inclined contact surface of the lower part of the lock block 45, and the lock block 45 is pushed into the corresponding mounting block 41 by the inclined surface guiding effect, at the same time, the lock block 45 drives the gear 48 to rotate through the flat tooth part 47, and the reset torsional spring 49 is twisted and deformed to store energy, until the connecting rod 42 is completely expanded to a flat state, the lock block 45 is flush with the connecting rod 42, then the reset torsional spring 49 releases the elastic force to drive the gear 48 to rotate back, and the gear 48 reversely drives the lock block 45 to be pushed into the locking structure of the connecting rod 42 through the flat tooth part 47, that is, the angle of the connecting rod 42 is fixed, the relative displacement of the adjacent support frames 12 is prevented, and the stability of the overall structure is ensured.

[0130] When the support frames 12 are close to each other, the locking assemblies will be unlocked step by step from front to back, when the front frame body 1201 is folded with the front side intermediate frame body 1203, the control part 4101 of the mounting block 41 on the front frame body 1201 contacts with the extension part of the control block 46 of the mounting block 41 on the front side intermediate frame body 1203, the control block 46 is slid by the pushing force, the lock block 45 on the front side intermediate frame body 1203 is retracted into the mounting block 41 through the transmission of the flat tooth part 47 and the gear 48, and the locking of the connecting assembly between the front side intermediate frame body 1203 and the rear side intermediate frame body 1203 is released, therefore, the front side intermediate frame body 1203 can be displaced backward, when it is folded to contact with the rear side intermediate frame body 1203, the control part 4101 triggers the control block 46 of the rear side intermediate frame body 1203, the connecting assembly between the rear side intermediate frame body 1203 and the rear frame body 1202 is unlocked, and the above logic is sequentially used to unlock, and finally all the connecting assemblies are unlocked, and the support frames 12 are smoothly folded.

[0131] Therefore, the locking assemblies of the roof are automatically locked and unlocked step by step, the connecting rods 42 are automatically locked when being expanded, the stability between the support frames 12 is ensured, the overall rigidity of the roof is improved, the connecting rods 42 are automatically unlocked step by step when being folded, no additional operation is needed, the structural stability and folding convenience are considered, and the use experience is optimized.

[0132] Referring to Figure 2 , Figure 13 and Figure 14 , the roof further comprises: a relocking assembly arranged on each mounting seat 11, used for locking the position of the intermediate frame body 1203, further enhancing the overall stability of the roof, and ensuring the safety in use, and each group of relocking assemblies comprises:

[0133] The moving frame 51 is slidingly installed in the mounting base 11 to move in the front-back direction;

[0134] The second reset spring 57 is fixedly installed between the moving frame 51 and the mounting base 11;

[0135] The first contact part 52 is fixedly installed on the front side of the moving frame 51, and when the front frame body 1201 is moved to the position by moving forward, the moving frame 51 is pushed to move forward by contacting with the first contact part 52;

[0136] The wedge-shaped part 53 is fixedly installed on the moving frame 51, and the number of the wedge-shaped part 53 corresponds to the number of the intermediate frame body 1203, and the position of the wedge-shaped part 53 is aligned with the position of the corresponding intermediate frame body 1203 when the intermediate frame body 1203 is fully unfolded, and the wedge-shaped part 53 is provided with an inclined contact surface;

[0137] The pushing frame 54 is slidingly installed in the mounting base 11 to move in the vertical direction, and the number and position of the pushing frame 54 correspond to the number and position of the wedge-shaped part 53, and the pushing frame 54 is provided with the second contact part 5401 which is in contact with the inclined surface of the wedge-shaped part 53;

[0138] And the insertion rod 55 is slidingly installed on the pushing frame 54, and the bottom of the intermediate frame body 1203 is provided with the insertion hole 5501, and the insertion rod 55 is in plug-in cooperation with the insertion hole 5501 to realize the rigid locking of the intermediate frame body 1203;

[0139] The first reset spring 56 is fixedly installed between the insertion rod 55 and the pushing frame 54, and is sleeved on the pushing frame 54 to provide the insertion rod 55 with elastic pre-tightening force, so as to ensure that the insertion rod 55 is in close cooperation with the insertion hole 5501, and at the same time, the insertion rod 55 is allowed to flexibly exit when being unlocked.

[0140] When the front frame body 1201 is moved to the unfolded position by the driving of the moving assembly, the front frame body 1201 will push the moving frame 51 to move forward synchronously by contacting with the first contact part 52, and the second reset spring 57 is compressed; the wedge-shaped part 53 on the moving frame 51 moves forward with the moving frame 51, and the wedge-shaped part 53 is pressed to move the second contact part 5401 by the inclined surface of the wedge-shaped part 53, so that the pushing frame 54 and the insertion rod 55 on the pushing frame 54 move upward; if the insertion rod 55 is not aligned with the insertion hole 5501 at the bottom of the intermediate frame body 1203 at this time, the insertion rod 55 is pressed by the bottom of the intermediate frame body 1203, and slides downward relative to the pushing frame 54, and the first reset spring 56 is compressed; when the intermediate frame body 1203 is moved to the unfolded position with the front frame body 1201, and the insertion hole 5501 is aligned with the insertion rod 55, the first reset spring 56 releases the elastic force to push the insertion rod 55 to insert into the insertion hole 5501, and the position locking of the intermediate frame body 1203 is completed;

[0141] Therefore, the front frame body 1201 is locked in the unfolded position by the moving assembly, the middle frame body 1203 is locked in the unfolded position by the double locking assembly, and the rear frame body 1202 is locked in the unfolded position by the positioning assembly. Therefore, the three cooperate to keep all the support frames 12 fixed in position after unfolding, avoid displacement of the support frames 12 due to external factors, and greatly improve the overall stability of the roof.

[0142] When the front frame body 1201 is displaced rearward to be folded: the front frame body 1201 is separated from the first contact part 52, the second reset spring 57 releases the elastic force, and the moving frame 51 is pulled rearward to return to the original position. The moving frame 51 drives the wedge-shaped part 53 to move away from under the push frame 54. After the push frame 54 loses the support of the wedge-shaped part 53, it descends under the action of gravity (more preferably, a reset spring can be arranged between the push frame 54 and the mounting seat 11, so that the push frame 54 can smoothly descend and reset). The insertion rod 55 is displaced downward synchronously and separated from the insertion hole 5501 of the middle frame body 1203, thereby releasing the locking of the middle frame body 1203, ensuring that the middle frame body 1203 can be smoothly folded with the front frame body 1201.

[0143] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
