Description

Technical Field

[0001] The present invention relates to the technical field of yurts, and specifically to an ice-expansion self-fastening module self-locking detachable and assembled yurt system. Background Art

[0002] In recent years, herdsmen in the hinterland of the grassland have required rotational grazing and migration according to seasonal changes and the situation of grassland vegetation, aiming to restore the grassland coverage and biomass. During the rotational grazing and migration process, the yurts, which are commonly used buildings by grassland herdsmen, have the following defects:

[0003] For traditional yurts, with wooden skeletons and felt as the main building materials, under the action of strong winds, the hemp ropes break and the covering materials such as felt fall off, further deteriorating the living conditions and posing certain safety hazards.

[0004] Under the combined action of extreme wind loads and snow loads, the wooden structure members of current herdsmen's yurts are prone to yield damage and deformation. Under the comprehensive influence of multiple factors such as strong winds, heavy snow, stress concentration, and material creep, the wooden structure accelerates aging and damage, and the node damage is particularly significant. At the same time, the drastic contraction of materials caused by sudden temperature changes in winter / summer, as well as the long-term repeated dismantling and assembly of wooden structure members, will inevitably result in poor node tightness, aging and looseness, and accelerate the problem of fastening failure of connecting components.

[0005] Some steel structure or partially prefabricated yurts developed in the current market, although some modular components are prefabricated and assembled on-site, have certain advantages. However, their node connections have insufficient stability, and the design of rigid components is unreasonable. The analysis of the coupling action of environmental loads is insufficient, and the degradation of the low-cycle fatigue performance of materials and the accumulation of residual stresses in the node area caused by temperature difference alternation and strong wind loads are not fully considered. The reversible connection design is not adopted, and the disassembly is difficult due to relying on temporary reinforcement measures. In addition, the installation nodes of these conventional prefabricated yurts need to be assembled on-site by means of welding, bolt connection, grouting connection, etc. The process requirements are high, it is difficult for herdsmen to operate, the quality control is difficult, and the nodes are mainly rigid nodes, which are prone to stress concentration. Moreover, the components are large and difficult to transport. Forcible disassembly will cause damage to the locking components, resulting in the structure becoming more and more loose, with a high frequency of damage and replacement, and reducing the service life.

[0006] There are many defects in the application of current prefabricated yurt technology, especially the limited load-bearing capacity of wooden and steel structure supports, and the obvious deficiencies in heat preservation performance and structural stability in extreme environments.

[0007] At the present stage, most prefabricated yurts are self-made. Although Patent CN114439274B adopts snap-in connection components and khana sheets as the wall structure, in actual application, the structural stability of the yurt and its ability to maintain the internal temperature may have certain limitations in strong wind weather or environments with large temperature differences, and the disassembly and assembly operations are complex.

[0008] Patent CN219910265U adopts a foldable Unni component for assembly structure. However, the installation process is complex. If the operation is improper, it may lead to stress concentration, which will have a potential destructive impact on the overall structure. Especially, the disassembly and assembly operations are complex, there are many small components, and the installation technical requirements are high. Therefore, we introduce an ice expansion self-fastening module self-locking detachable yurt system. Summary of the Invention

[0116] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0117] Please refer to Figures 1 - 36 , The present invention provides a technical solution:

[0118] An ice-expansion self-fastening module self-locking detachable yurt system, comprising several groups of vertical enclosures 3, several groups of roof members 6 and a group of yurt top assemblies 8;

[0119] When the vertical enclosure 3 is produced, according to different environmental conditions, an inclination angle of 3-5° can be set on the outer side of the vertical enclosure 3.

[0120] The roof member 6 is fixed to the top of the vertical enclosure 3 by a wall locking device 9;

[0121] As Figures 33 - 35 shown, a connecting projection seat 602 is provided on the inner side of the bottom of the roof member 6. The wall locking device 9 includes an upper connecting screw 901 whose top is inserted into the first connecting hole at the bottom of the connecting projection seat 602, an expanding steel assembly 903 sleeved on the outer side of the upper connecting screw 901, and an external thread cylinder 902. After the expanding steel assembly 903 expands, it is stuck in the first connecting hole, and the external thread cylinder 902 is screwed into the second connecting hole at the top of the vertical enclosure 3;

[0122] An internal thread hole 9021 for screwing with the upper connecting screw 901 is further provided in the middle of the external thread cylinder 902;

[0123] The expansion steel assembly 903 includes a connecting sleeve 9031 sleeved outside the upper connecting screw 901 and several groups of corrugated steel sheets 9032 equally spaced at the top of the connecting sleeve 9031. A connecting ring 9033 sleeved outside the upper connecting screw 901 is connected to the tops of the several groups of corrugated steel sheets 9032.

[0124] During connection, first insert the top of the upper connecting screw 901 into the first connection hole at the bottom of the connecting convex seat 602, and then successively sleeve the expansion steel assembly 903 and the external thread cylinder 902 outside the upper connecting screw 901. Since an internal thread hole 9021 screwed to the upper connecting screw 901 is also provided in the middle of the external thread cylinder 902, tighten the external thread cylinder 902 with the upper connecting screw 901, so that the external thread cylinder 902 pushes the expansion steel assembly 903 upward into the first connection hole at the bottom of the connecting convex seat 602 until the connecting sleeve 9031 pushes several groups of corrugated steel sheets 9032 upward, causing the several groups of corrugated steel sheets 9032 to deform and expand in the first connection hole. In this way, the firm installation of the upper connecting screw 901 and the connecting convex seat 602 can be realized through the expansion steel assembly 903.

[0125] Subsequently, insert the bottom of the upper connecting screw 901 into the second connection hole at the top of the vertical enclosure wall 3, and then reversely rotate the external thread cylinder 902 so that the external thread cylinder 902 moves downward along the upper connecting screw 901 to the second connection hole. At this time, the outside of the external thread cylinder 902 is screwed and fixed to the second connection hole, and the internal thread hole 9021 inside the external thread cylinder 902 is still screwed to the upper connecting screw 901. In this way, the top plate member 6 can be fixed to the top of the vertical enclosure wall 3 through the upper connecting screw 901 and the external thread cylinder 902 of the wall body locking device 9.

[0126] When it is necessary to disassemble the top plate member 6 and the vertical enclosure wall 3, only need to rotate the external thread cylinder 902 again so that the external thread cylinder 902 moves upward along the upper connecting screw 901 until the external thread cylinder 902 disengages from the second connection hole, and then pull out the bottom of the upper connecting screw 901 from the second connection hole to remove the top plate member 6. Such disassembly is convenient.

[0127] The first wall body locking self-tightening device 1 and the second wall body locking self-tightening device 2 are respectively installed on both sides of the vertical enclosure wall 3 and the top plate member 6, and a stress return rotation device 5 is used to connect the vertical enclosure wall 3 and the first wall body locking self-tightening device 1 thereon.

[0128] A first rubber cover plate 10 for covering and shielding the stress return rotation device 5 is provided at the connection between the vertical enclosure wall 3 and the corresponding first wall body locking self-tightening device 1.

[0129] A second rubber cover plate 4 for covering and shielding the corresponding first wall body locking self-tightening device 1 and the second wall body locking self-tightening device 2 is provided at the connection between adjacent top plate members 6.

[0130] As shown Figure 7 , 14 , as shown in Fig. 15, the second wall locking self-tightening device 2 includes a second fixed seat 201 fixed on the same side of the vertical enclosure wall 3 and the top plate member 6, side plates 202 symmetrically connected to the side of the second fixed seat 201, and a triangular plate 203 provided on the inner side of the end of the side plates 202;

[0131] As shown Figures 7 - 15 , the first wall locking self-tightening device 1 includes a first fixed seat 111, trapezoidal steel columns 112 symmetrically installed on both sides of the first fixed seat 111, and an upper bolt rod 107 and a lower bolt rod 110 vertically distributed between the two groups of trapezoidal steel columns 112;

[0132] The first fixed seat 111 is connected to the inner sides of the two groups of trapezoidal steel columns 112 by a sliding device 103 and an expansion device 106, and a fastening device 105 is also connected to the inner sides of the two groups of trapezoidal steel columns 112;

[0133] The sliding device 103 includes a connection shell 1031 fixed on the first fixed seat 111, sliders 1033 slidably connected to both ends of a chute 1032 inside the connection shell 1031, and a first connection block 1034 fixed on the sliders 1033 through an extension plate 1035, and the first connection block 1034 is fixed to the inner wall of the corresponding trapezoidal steel column 112;

[0134] When the two groups of trapezoidal steel columns 112 approach or move away from each other, the trapezoidal steel columns 112 will drive the sliders 1033 to move horizontally along the chute 1032 through the first connection block 1034 and the extension plate 1035. In this way, when the two groups of trapezoidal steel columns 112 approach or move away from each other, it can be ensured that the trapezoidal steel columns 112 are in a horizontal moving state and the trapezoidal steel columns 112 will not tilt.

[0135] Through the dynamic adjustment of the trapezoidal steel columns 112 and the sliding device 103, the locking of the first wall locking self-tightening device 1 and the second wall locking self-tightening device 2 is strengthened, and the locking tightness and structural stability between the vertical enclosure walls 3 are improved, thereby further realizing the structural integrity and stability of the yurt during long-term service.

[0136] The fastening device 105 includes a screw connection seat 1051 and second connection blocks 1056 movably connected to both sides of the screw connection seat 1051 through connection arms 1054. The second connection blocks 1056 are fixed to the inner walls of the corresponding trapezoidal steel columns 112. One end of the connection arm 1054 is movably connected to a first slot 1052 on the side of the screw connection seat 1051 through a first pin shaft 1053, and the other end of the connection arm 1054 is movably connected to a second slot 1057 on the side of the second connection block 1056 through a second pin shaft 1055;

[0137] The expansion device 106 includes a through seat 1061 and connecting plates 1063 connected by expansion springs 1062 on both sides of the through seat 1061. The connecting plates 1063 are fixed to the inner walls of the corresponding trapezoidal steel columns 112.

[0138] First limit posts 101 and second limit posts 104 are provided at both the upper and lower parts of the side of the first fixed seat 111. The upper bolt rod 107 passes through the corresponding first limit post 101 and second limit post 104 and is fixed with a connecting cylinder 108. The lower bolt rod 110 passes through the corresponding first limit post 101 and second limit post 104 and is fixed with a square steel column 109. The square steel column 109 is inserted into the square slot inside the connecting cylinder 108.

[0139] As Figure 8 、 9 As shown in Figures 10 and 14, bolt heads 114 are fixed at the upper ends of the upper bolt rod 107 and the lower ends of the lower bolt rod 110. The wrench can rotate the upper bolt rod 107 or the lower bolt rod 110 through the corresponding bolt head 114, and the upper bolt rod 107 and the lower bolt rod 110 are driven by the connecting cylinder 108 to rotate synchronously.

[0140] A trapezoidal cushion plate 115 is provided on the side of the first fixed seat 111.

[0141] Limit rings 113 are fixed on both the upper bolt rod 107 and the lower bolt rod 110. The first springs 102 sleeved on the upper bolt rod 107 and the lower bolt rod 110 are located between the corresponding first limit posts 101 and limit rings 113.

[0142] The upper bolt rod 107 and the lower bolt rod 110 are screwed to the middle of the corresponding screwed seat 1051, and the upper bolt rod 107 and the lower bolt rod 110 pass through the middle of the screwed seat 1051. The upper bolt rod 107 and the lower bolt rod 110 pass through the middle of the corresponding through seat 1061.

[0143] When the adjacent vertical enclosures 3 start to be butted through the first wall latch self - tightening device 1 and the second wall latch self - tightening device 2, by rotating the upper bolt rod 107, the connecting cylinder 108 drives the square steel column 109 and the lower bolt rod 110 to rotate together, causing the upper bolt rod 107 to move downward and the lower bolt rod 110 to move upward simultaneously, so that the upper and lower first springs 102 are in an extended state.

[0144] When the first wall latch self - tightening device 1 contacts the corresponding second wall latch self - tightening device 2, the trapezoidal steel column 112 contacts the triangular plate 203, causing the two groups of trapezoidal steel columns 112 to approach each other. This causes the sliding device 103 to contract, and at the same time, the expansion spring 1062 in the expansion device 106 is in a compressed state, and the fastening device 105 also contracts.

[0145] When the fastening device 105 contracts, the two groups of second connecting blocks 1056 approach each other, so that the second connecting blocks 1056 push up the screw joint seat 1051 through the connecting arms 1054. Under the contraction effect of the fastening device 105, the screw joint seat 1051 moves the upper bolt rod 107 upward, while the lower bolt rod 110 moves downward, further compressing the first spring 102.

[0146] After the two trapezoidal steel columns 112 slide past the triangular plate 203 and completely enter between the two side plates 202 of the second wall locking and self-tightening device 2, under the elastic force of the first spring 102 and the expansion spring 1062 of the expansion device 106, the two trapezoidal steel columns 112 move away from each other and are stuck inside the triangular plate 203.

[0147] When the trapezoidal cushion plate 115 contacts the second wall locking and self-tightening device 2, rotate the upper bolt rod 107 in the reverse direction to make it move upward, and at the same time, the lower bolt rod 110 moves downward, further compressing the two upper and lower first springs 102.

[0148] As the upper bolt rod 107 rotates in the reverse direction, since the upper bolt rod 107 is screwed to the middle of the corresponding screw joint seat 1051, the corresponding screw joint seat 1051 moves downward relative to the upper bolt rod 107. The screw joint seat 1051 on the upper bolt rod 107 pushes open the two groups of second connecting blocks 1056 through the connecting arms 1054, making the two groups of second connecting blocks 1056 move away from each other, and the fastening device 105 gradually expands.

[0149] At the same time, the lower bolt rod 110 also rotates synchronously. Since the lower bolt rod 110 is screwed to the middle of the corresponding screw joint seat 1051, the corresponding screw joint seat 1051 moves upward relative to the lower bolt rod 110. The screw joint seat 1051 on the lower bolt rod 110 pushes open the two groups of second connecting blocks 1056 through the connecting arms 1054, making the two groups of second connecting blocks 1056 move away from each other, and the fastening device 105 gradually expands.

[0150] Under the combined action of the expansion of the fastening device 105, the elastic force of the first spring 102 and the expansion spring 1062 of the expansion device 106, the two trapezoidal steel columns 112 show a tendency to expand. The two trapezoidal steel columns 112 move away from each other and are stuck inside the triangular plate 203. At the same time, under the action of the triangular plate 203 on the second wall locking and self-tightening device 2, when the outer surface of the trapezoidal steel column 112 contacts the inner surface of the triangular plate 203, the first wall locking and self-tightening device 1 has a tendency to move inward, so that the first wall locking and self-tightening device 1 and the second wall locking and self-tightening device 2 are tightly locked.

[0151] The installation between adjacent vertical enclosures 3 and between adjacent roof members 6 is realized through the connection of the corresponding first wall locking and self-tightening device 1 and the second wall locking and self-tightening device 2.

[0152] The stress resilience rotating device 5 is used to lock the included angle of the vertical enclosure wall 3 and disperse the concentrated stress received by the vertical enclosure wall 3;

[0153] The top plate member 6 is directly fixedly connected to the corresponding first fixing seat 111, and the vertical enclosure wall 3 is connected to the corresponding first fixing seat 111 by the stress resilience rotating device 5;

[0154] The stress resilience rotating device 5 includes a rotating shaft 505 fixed on the corresponding first fixing seat 111, a cylindrical gear 508 and an upper inclined surface cylinder 506 sleeved on the rotating shaft 505, upper and lower groups of limit connection sleeves 502 fixed on the side of the vertical enclosure wall 3, and a limit sleeve 504 located between the upper and lower groups of limit connection sleeves 502;

[0155] The rotating shaft 505 is fixedly connected to the corresponding first fixing seat 111 by two groups of fixing rods 503 and a group of lower inclined surface cylinders 507, and the lower inclined surface cylinder 507 is located between the two groups of fixing rods 503;

[0156] The limit connection sleeve 502 is sleeved on the rotating shaft 505. Two groups of limit discs 5051 are provided at the upper and lower parts of the rotating shaft 505, and the second spring 501 sleeved on the rotating shaft 505 is located between the limit connection sleeve 502 and the limit disc 5051;

[0157] The inclined surface at the bottom of the upper inclined surface cylinder 506 closely adheres to the inclined surface at the top of the lower inclined surface cylinder 507;

[0158] An upper tooth seat 5082 is fixed at the bottom of the cylindrical gear 508, a lower tooth seat 5061 is provided at the top of the upper inclined surface cylinder 506, and the upper tooth seat 5082 is engaged with the lower tooth seat 5061;

[0159] The cylindrical gear 508 is engaged with the internal tooth groove 5041 on the inner wall of the limit sleeve 504, and two groups of locking screws 5042 fixed on the limit sleeve 504 are inserted into the reserved groove 5081 on the side of the cylindrical gear 508 to fix the cylindrical gear 508 and the limit sleeve 504.

[0160] After the first wall locking self-tightening device 1 is connected to the vertical enclosure wall 3 through the stress resilience rotating device 5, the cylindrical gear 508 needs to be lifted upward until it disengages from the limit sleeve 504.

[0161] Subsequently, rotate the first wall locking self-tightening device 1 to the fixed position, and rotate the upper inclined surface cylinder 506 to ensure that the inclined surface at the top of the lower inclined surface cylinder 507 is parallel to and in contact with the inclined surface at the bottom of the upper inclined surface cylinder 506.

[0162] Next, lower the cylindrical gear 508 so that the upper tooth seat 5082 at the bottom of the cylindrical gear 508 engages with the lower tooth seat 5061 at the top of the upper inclined surface cylinder 506, and use the locking screw 5042 to connect the cylindrical gear 508 and the limit sleeve 504, achieving precise control of the angle between adjacent vertical enclosures 3.

[0163] During use, if the vertical enclosure 3 or the first wall locking self-tightening device 1 rotates due to improper operation or stress concentration, the lower inclined surface cylinder 507 will rotate relative to the upper inclined surface cylinder 506 and the cylindrical gear 508, and push up the cylindrical gear 508.

[0164] However, under the fixed connection of the limit sleeve 504 to the cylindrical gear 508, the vertical enclosure 3 will move upward following the cylindrical gear 508. However, under the combined action of gravity and the elastic force of the second spring 501, the vertical enclosure 3 will descend again and return to its original position, thereby effectively resisting stress concentration.

[0165] The top of the top plate member 6 is connected to the outside of the yurt top assembly 8 by an ice expansion self-locking connector 7. The ice expansion self-locking connector 7 ensures a firm connection between the top plate member 6 and the yurt top assembly 8 through its self-tightening function.

[0166] The outside of the yurt top assembly 8 is covered with a rubber cover 11. The bottom of the rubber cover 11 covers and shields the connection between the yurt top assembly 8 and the top plate member 6, that is, the rubber cover 11 can cover and shield the ice expansion self-locking connector 7.

[0167] The ice expansion self-locking connector 7 includes a docking box 709, a rear top plate 705 and a front top plate 710 fixedly connected, and expansion mechanisms 702 fixed on both sides of the rear top plate 705. The expansion mechanisms 702 are inserted into the interior of the docking box 709;

[0168] The docking box 709 is connected to the top of the top plate member 6 by a first bolt 601, and the rear top plate 705 is connected to the yurt top assembly 8 by a second bolt 7051;

[0169] As Figure 36 shown, the yurt top assembly 8 is composed of four I-shaped steel channels 801 spliced by a third bolt 803, and the second bolt 7051 on the rear top plate 705 passes through the arc-shaped through groove 802 on the I-shaped steel channel 801 and is locked to fix the rear top plate 705 and the I-shaped steel channel 801.

[0170] Three sets of spring boxes 701 distributed in a triangular shape are fixed on the top of the rear top plate 705 by brackets 720. The three sets of spring boxes 701 are respectively connected to a first rotating rod 706, a second rotating rod 707 and a third rotating rod 708 by ratchet assemblies;

[0171] The ratchet assembly includes three sets of spring boxes 7013 fixed to the top of the bracket 720, a spring box cover plate 7011 fixed to the top of the spring box 7013, slotted sleeves 7017 sleeved on the outer sides of the first rotating rod 706, the second rotating rod 707, and the third rotating rod 708 respectively, and a spring 7012 sleeved on the outer side of the slotted sleeve 7017;

[0172] The bottom of the slotted sleeve 7017 is centrally fixed inside the spring box 7013, and a first ratchet 7015 is fixed after the top of the slotted sleeve 7017 extends out of the spring box cover plate 7011;

[0173] The outer end of the spring 7012 is fixed with a spring rotating rod 7014. The bottom of the spring rotating rod 7014 is inserted into the shaft hole inside the spring box 7013, and a first pawl 7016 is fixed after the top of the spring rotating rod 7014 extends out of the spring box cover plate 7011;

[0174] The first pawl 7016 is engaged with the first ratchet 7015;

[0175] The inner end of the spring 7012 extends into the inside of the slotted sleeve 7017 through the side slot 70171 on the slotted sleeve 7017 and is then fixed to the corresponding first rotating rod 706, second rotating rod 707, and third rotating rod 708.

[0176] Both the bottoms of the first rotating rod 706 and the second rotating rod 707 are fixedly connected with a second ratchet 715 and a long gear 717. The long gears 717 are respectively engaged with the rack plates 704 on the inner wall of the docking box 709, and U-shaped avoidance slots 7091 for respectively accommodating the first rotating rod 706 and the second rotating rod 707 are provided on both sides of the top of the docking box 709;

[0177] Both ends of the bracket 720 are also movably connected with a second pawl 716 by a third pin shaft 721. An adjusting member is connected between the two groups of second pawls 716, and the second pawl 716 is engaged with the corresponding second ratchet 715 through the adjusting member;

[0178] The adjusting member includes an intermediate adjusting nut 719 and threaded lead screws 718 screwed inside both ends of the intermediate adjusting nut 719. The ends of the threaded lead screws 718 are inserted into the corresponding reserved holes on the sides of the second pawl 716.

[0179] Both the upper and lower ends of the outer side of the rack plate 704 are fixed to the inner wall of the docking box 709 by a raised plate 7041, so that an insertion cavity 7092 for inserting the expansion mechanism 702 is formed between the inner wall of the docking box 709, the rack plate 704, and the raised plate 7041;

[0180] Such as Figure 31 And 32As shown, the expansion mechanism 702 includes side seats 7022 fixed on both sides of the rear top plate 705, cylinder barrels 70221 arranged at equal intervals up and down inside the side seats 7022, piston shafts 7021 arranged inside the cylinder barrels 70221, and rubber piston heads 7023 and piston top blocks 7024 fixed at both inner and outer ends of the piston shafts 7021 respectively;

[0181] The cylinder barrels 70221 are filled with salt solution, and the piston top blocks 7024 extend into the insertion cavity 7092 and abut against the inner wall of the docking box 709.

[0182] The bottom of the third rotating rod 708 extends into the rear top plate 705 and is fixedly connected with a first bevel gear 711;

[0183] The first bevel gear 711 meshes with a second bevel gear 7121 inside the rear top plate 705. A rotating rod 712 fixed in the middle of the second bevel gear 7121 extends out of the rear top plate 705 and is fixed with a dial plate 713. A raised dial block 7131 is provided at the end of the dial plate 713;

[0184] Three mechanical lock beams 703 with trapezoidal grooves 7031 are provided inside the docking box 709, and rectangular insertion through grooves 7101 for inserting the mechanical lock beams 703 are provided on the front top plate 710;

[0185] The front top plate 710 and the rear top plate 705 are fixedly connected by three fixed shafts 7146 distributed in an equilateral triangle, and the fixed shafts 7146 also penetrate through a mechanical lock tongue assembly 714 fixed on the inner wall of the front top plate 710;

[0186] The mechanical lock tongue assembly 714 includes a lock tongue rear plate 7141 and a lock tongue front plate 7142 that fit together;

[0187] One end of the first smooth rod 7150 on the outer side of the lock tongue rear plate 7141 penetrates through a first limit plate 7149 fixed on the inner wall of the front top plate 710. A first return spring 7148 is sleeved on the first smooth rod 7150, and the first return spring 7148 is located between the lock tongue rear plate 7141 and the first limit plate 7149;

[0188] A buckle extension convex block 71412 is provided at the other end of the outer side of the lock tongue rear plate 7141, and a vertical through groove 71411 for penetrating the fixed shaft 7146 is provided on the lock tongue rear plate 7141;

[0189] Lock tongues 7145 and second smooth rods 7143 are respectively provided on both sides of the lock tongue front plate 7142. The second smooth rods 7143 penetrate through a second limit plate 7147 fixed on the inner wall of the front top plate 710. A second return spring 7144 is sleeved on the second smooth rods 7143, and the second return spring 7144 is located between the lock tongue front plate 7142 and the second limit plate 7147;

[0190] The outer end of the lock tongue front plate 7142 is provided with a plurality of limit grooves 71423 for clamping the buckle extension protrusion 71412, and the inner end of the lock tongue front plate 7142 corresponding to the dial plate 713 is provided with a plurality of dial grooves 71421 for clamping the raised dial block 7131. The lock tongue front plate 7142 is provided with a horizontal through groove 71422 for passing the fixed shaft 7146, and a blocking piece 71461 is also fixed on the fixed shaft 7146 to block the inner side of the lock tongue front plate 7142.

[0191] like Figure 27 , 28 As shown in Figures 29, when the dial plate 713 rotates clockwise and the protruding block 7131 on the dial plate 713 reaches the driving groove 71421 below the lock tongue front plate 7142, the top of the protruding block 7131 contacts the bottom of the lock tongue rear plate 7141, and the lock tongue rear plate 7141 is lifted up (at this time, the first return spring 7148 is gradually in a compressed state), and under the rotation of the protruding block 7131, the lock tongue front plate 7142 is pushed to move to the right (at this time, the second return spring 7144 is gradually in a compressed state);

[0192] Subsequently, after the protruding shifting block 7131 leaves the shifting groove 71421, under the elastic force of the first return spring 7148 on the lock tongue rear plate 7141, the lock tongue rear plate 7141 will move downward and return to its original position. At this time, the buckle extension protrusion 71412 on the lock tongue rear plate 7141 will be stuck in the leftmost limiting slot 71423 on the lock tongue front plate 7142, so that the lock tongue 7145 can be retracted.

[0193] In this way, after the third rotating rod 708 is continuously turned to make the dial plate 713 continuously rotate clockwise, the locking tongues 7145 on the three clockwise arranged mechanical locking tongue assemblies 714 can all be retracted.

[0194] like Figure 27 and 30 As shown, when the dial plate 713 rotates counterclockwise and the protruding block 7131 on the dial plate 713 reaches the driving groove 71421 below the lock tongue front plate 7142, the top of the protruding block 7131 contacts the bottom of the lock tongue rear plate 7141, and lifts up the lock tongue rear plate 7141 (at this time, the first return spring 7148 is gradually in a compressed state), and under the rotation of the protruding block 7131, the lock tongue front plate 7142 is pushed to move to the left (at this time, the second return spring 7144 is gradually in an extended state);

[0195] Subsequently, after the convex toggle block 7131 leaves the toggle groove 71421, under the elastic force of the first return spring 7148 on the rear lock tongue plate 7141, the rear lock tongue plate 7141 will move downward and reset. At this time, the buckle extension convex block 71412 on the rear lock tongue plate 7141 will be stuck in the rightmost limit card slot 71423 on the front lock tongue plate 7142, realizing the protrusion of the lock tongue 7145.

[0196] In this way, by continuously turning the third rotating rod 708 to make the dial 713 continuously rotate counterclockwise, the lock tongues 7145 on the three clockwise arranged mechanical lock tongue assemblies 714 can all protrude, and finally the lock tongue 7145 extends into the trapezoidal groove 7031 of the mechanical lock beam 703.

[0197] When the ice expansion self-locking connector 7 is docked, the same concentration of salt solution needs to be injected into the cylinder 70221 of the side seat 7022. Subsequently, the docking box 709 is pushed to insert the mechanical lock beam 703 into the rectangular insertion through groove 7101 of the front top plate 710, and it is ensured that the long gear 717 meshes with the inner side of the corresponding rack plate 704.

[0198] At the same time, the first rotating rod 706 and the second rotating rod 707 are rotated to make the two groups of long gears 717 rotate synchronously on the inner sides of the corresponding rack plates 704, so as to drive the docking box 709 to move towards the direction close to the rear top plate 705.

[0199] When the mechanical lock beam 703 contacts the rear top plate 705, by turning the intermediate adjusting nut 719, the threaded lead screw 718 extends out, pushing the second pawl 716 to rotate around the third pin shaft 721 until the second pawl 716 locks the second ratchet wheel 715. Then, by turning the third rotating rod 708, the first bevel gear 711 will drive the rotating rod 712 and the dial 713 to rotate counterclockwise through the second bevel gear 7121;

[0200] In this way, by continuously turning the third rotating rod 708 to make the dial 713 continuously rotate clockwise, the lock tongues 7145 on the three clockwise arranged mechanical lock tongue assemblies 714 can all protrude, that is, the lock tongue 7145 extends into the trapezoidal groove 7031 of the mechanical lock beam 703;

[0201] Finally, turn the corresponding winding rod 7014 to wind the internal winding spring 7012 until the first pawl 7016 is stuck on the first ratchet wheel 7015. Then, under the elastic force of the winding spring 7012, the first rotating rod 706 and the second rotating rod 707 have a rotational tendency to self-tighten the ice-expansion self-locking connector 7. That is, under the elastic force of the winding spring 7012, the first rotating rod 706 and the second rotating rod 707 have a tendency to drive the long gear 717 to rotate inside the corresponding rack plate 704, thereby driving the docking box 709 to move towards the rear top plate 705 to achieve the self-tightening effect of the ice-expansion self-locking connector 7.

[0202] During the service process of the ice-expansion self-locking connector 7, in an environment with continuously decreasing temperature, due to the thermal expansion, contraction, and creep characteristics of the material, the connection of the ice-expansion self-locking connector 7 will become loose. A rubber piston head 7023 is installed on the piston shaft 7021 to prevent the leakage of the salt solution in the cylinder 70221. The salt solution will freeze and expand at different temperatures, thereby pushing the piston shaft 7021 and pushing the piston top block 7024 against the docking box 709, so that the docking box 709 and the rear top plate 705 of the loose ice-expansion self-locking connector 7 are tightened, thus enhancing the stability and safety of the connection between the top plate member 6 and the yurt top assembly 8.

[0203] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
