Description

Technical Field

[0001] The invention relates to the technical field of yurts, in particular to a self-locking detachable yurt system with ice expansion self-fastening modules. Background Art

[0002] In recent years, herders in the hinterland of the grassland have requested rotational migration in accordance with seasonal changes and grassland vegetation conditions, with the aim of restoring grassland coverage and biomass. During the rotational migration process, the yurts commonly used by herders have the following defects: Traditional yurts are mainly built with wooden frames and felt. Under the influence of strong winds, hemp ropes may break and felt and other coverings may fall off, further deteriorating living conditions and posing certain safety hazards.

[0003] At present, the wood structure rods of herders' yurts are prone to yield damage and deformation under the combined effects of extreme wind loads and snow loads. Under the combined influence of multiple factors such as strong winds, heavy snow, stress concentration and material creep, the wood structure accelerates aging and damage, and the damage to the nodes is particularly significant. At the same time, the drastic shrinkage of materials caused by sudden temperature changes in winter and summer, as well as the long-term and repeated dismantling and assembly of wood structure rods, will inevitably lead to poor node tightness, aging and looseness, and accelerated failure of the fastening of connecting parts.

[0004] Some steel structures or partially assembled yurts currently developed in the market, although they are advanced in that some modular components are prefabricated and then assembled on site, their node connections are insufficiently stable, and the rigid components are not designed reasonably. The analysis of the coupling effect of environmental loads is insufficient, and the degradation of the low-cycle fatigue performance of materials caused by temperature changes and strong wind loads and the accumulation of residual stress in the node area are not fully considered; reversible connection design is not adopted, and temporary reinforcement measures are relied on, resulting in difficulty in disassembly. In addition, the installation nodes of these conventional assembled yurts need to be assembled on site through welding, bolting, grouting, etc., which have high process requirements, are difficult for herders to operate, and are difficult to control in quality. In addition, the nodes are mainly rigid nodes, which are prone to stress concentration, and the components are large and difficult to transport. Forced dismantling will cause damage to the locking components, resulting in an increasingly loose structure, a high frequency of replacement when damaged, and a reduced service life.

[0005] The current application of prefabricated yurt technology has many defects, especially the limited load-bearing capacity of wooden and steel structure supports, and the obvious lack of thermal insulation performance and structural stability in extreme environments.

[0006] At present, most assembled yurts are homemade. Although patent CN114439274B uses snap-on connection components and Hana sheets as wall structures, in actual applications, this design may have certain limitations in the structural stability and internal temperature maintenance ability of the yurt in strong winds or environments with large temperature differences, and the disassembly and assembly operations are complicated.

[0007] Patent CN219910265U uses foldable uni components for assembly. However, the installation process is complicated. If the operation is improper, it may cause stress concentration, which will cause potential destructive effects on the overall structure. In particular, the disassembly and assembly operation is complicated, there are many small components, and the installation technology requirements are high. For this reason, we have launched a self-locking detachable yurt system with ice expansion self-tightening modules. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-36 , the present invention provides a technical solution: An ice expansion self-tightening module self-locking detachable yurt system, comprising a plurality of groups of vertical walls 3, a plurality of groups of top panels 6 and a group of yurt top components 8; During production, the vertical fence 3 can be provided with an inclination angle of 3-5° on the outer side of the vertical fence 3 according to different environmental conditions.

[0025] The top plate member 6 is fixed to the top of the vertical wall 3 by a wall lock 9; like Figure 33-35 As shown, a connecting protrusion seat 602 is provided on the inner side of the bottom of the top plate 6, and the wall locker 9 includes an upper connecting screw 901 whose top is inserted into the first connecting hole at the bottom of the connecting protrusion seat 602, an expansion steel component 903 and an external threaded barrel 902 sleeved on the outer side of the upper connecting screw 901, and the expansion steel component 903 is stuck in the first connecting hole after expansion, and the external threaded barrel 902 is screwed into the second connecting hole at the top of the vertical wall 3; The middle part of the external threaded barrel 902 is also provided with an internal threaded hole 9021 which is threadedly connected to the upper connecting screw 901; The expansion steel assembly 903 includes a connecting sleeve 9031 sleeved on the outside of the upper connecting screw 901 and a plurality of groups of corrugated steel sheets 9032 evenly spaced on the top of the connecting sleeve 9031 .

The inner side of the two sets of trapezoidal steel columns 112 is also connected with a fastening device 105. The sliding device 103 includes a connecting shell 1031 fixed on the first fixing seat 111, a sliding block 1033 slidably connected to both ends of a sliding groove 1032 inside the connecting shell 1031, and a first connecting block 1034 fixed on the sliding block 1033 through an extended plate 1035. The first connecting block 1034 is fixed to the inner wall of the corresponding trapezoidal steel column 112; When the two groups of trapezoidal steel columns 112 approach or move away from each other, the trapezoidal steel columns 112 will drive the slider 1033 to move horizontally along the slide groove 1032 through the first connecting block 1034 and the extending 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 movement state and the trapezoidal steel columns 112 will not tilt.

[0028] Through the dynamic adjustment of the trapezoidal steel column 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 walls 3 are improved, thereby further realizing the structural integrity and stability of the yurt in long-term service.

[0029] The fastening device 105 includes a screw seat 1051 and a second connection block 1056 movably connected to the screw seat 1051 on both sides through a connection arm 1054, the second connection block 1056 is fixed to the inner wall of the corresponding trapezoidal steel column 112, one end of the connection arm 1054 is movably connected to the first slot 1052 on the side of the screw seat 1051 through a first pin shaft 1053, and the other end of the connection arm 1054 is movably connected to the second slot 1057 on the side of the second connection block 1056 through a second pin shaft 1055; The expansion device 106 includes a through seat 1061 and a connecting plate 1063 connected on both sides of the through seat 1061 by using an expansion spring 1062, and the connecting plate 1063 is fixed to the inner wall of the corresponding trapezoidal steel column 112; The first fixing seat 111 is provided with a first limiting pile 101 and a second limiting pile 104 at the upper and lower parts of the side, and an upper bolt rod 107 passes through the corresponding first limiting pile 101 and the second limiting pile 104 and is fixed with a connecting tube 108, and a lower bolt rod 110 passes through the corresponding first limiting pile 101 and the second limiting pile 104 and is fixed with a square steel column 109, and the square steel column 109 is inserted into a square slot inside the connecting tube 108; like Figure 8 , 9 , 10 and 14, the upper end of the upper bolt rod 107 and the lower end of the lower bolt rod 110 are fixed with a bolt head 114, and the wrench can rotate the upper bolt rod 107 or the lower bolt rod 110 through the corresponding bolt head 114, and make the upper bolt rod 107 and the lower bolt rod 110 rotate synchronously through the driving of the connecting tube 108; A trapezoidal pad 115 is provided on the side of the first fixing seat 111; The upper bolt rod 107 and the lower bolt rod 110 are both fixed with a limiting ring 113, and the first spring 102 sleeved on the upper bolt rod 107 and the lower bolt rod 110 is located between the corresponding first limiting pile 101 and the limiting ring 113; The upper bolt rod 107 and the lower bolt rod 110 are threadedly connected to the middle of the corresponding threaded seat 1051 , and the upper bolt rod 107 and the lower bolt rod 110 pass through the middle of the threaded seat 1051 , and the upper bolt rod 107 and the lower bolt rod 110 pass through the middle of the corresponding penetrating seat 1061 .

[0030] When the adjacent vertical enclosure walls 3 begin to dock through the first wall locking self-tightening device 1 and the second wall locking self-tightening device 2, by rotating the upper bolt rod 107, the connecting tube 108 drives the square steel column 109 and the lower bolt rod 110 to rotate together, so that the upper bolt rod 107 moves downward, and the lower bolt rod 110 moves upward, so that the upper and lower first springs 102 are in an extended state; When the first wall locking self-tightening device 1 contacts the corresponding second wall locking self-tightening device 2, the trapezoidal steel column 112 contacts the triangular plate 203, so that the two sets of trapezoidal steel columns 112 are close to each other, so that the sliding device 103 contracts, and the expansion spring 1062 in the expansion device 106 is in a compressed state, and the fastening device 105 also contracts; When the fastening device 105 contracts, the two groups of second connecting blocks 1056 approach each other, so that the second connecting blocks 1056 lift up the screw seat 1051 through the connecting arm 1054. Under the contraction of the fastening device 105, the screw seat 1051 causes the upper bolt rod 107 to move upward, while the lower bolt rod 110 moves downward, further causing the first spring 102 to be in a compressed state.

[0031] When the two trapezoidal steel columns 112 slide over the triangular plate 203 and completely enter between the two sets of side plates 202 of the second wall locking 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 get stuck on the inner side of the triangular plate 203; When the trapezoidal pad 115 contacts the second wall locking self-tightening device 2, the upper bolt rod 107 is rotated in the opposite direction to move it upward, and at the same time, the lower bolt rod 110 moves downward to further compress the upper and lower first springs 102; As the upper bolt rod 107 rotates in the opposite direction, since the upper bolt rod 107 is screwed with the middle part of the corresponding screw seat 1051, the corresponding screw seat 1051 moves downward relatively along the upper bolt rod 107, and the screw seat 1051 on the upper bolt rod 107 pushes the two groups of second connection blocks 1056 apart through the connecting arm 1054, so that the two groups of second connection blocks 1056 move away from each other, so that the fastening device 105 is gradually spread out; At the same time, the lower bolt rod 110 also rotates synchronously, and because the lower bolt rod 110 is screwed with the middle part of the corresponding screw seat 1051, the corresponding screw seat 1051 moves upward relatively along the lower bolt rod 110, and the screw seat 1051 on the lower bolt rod 110 pushes the two groups of second connection blocks 1056 apart through the connecting arm 1054, so that the two groups of second connection blocks 1056 are separated from each other, so that the fastening device 105 is gradually opened; When the fastening device 105 is stretched open, the first spring 102 and the expansion spring 1062 of the expansion device 106 jointly act, the two trapezoidal steel columns 112 show an expansion tendency, and the two trapezoidal steel columns 112 move away from each other and get stuck on the inner side of the triangular plate 203. At the same time, under the action of the triangular plate 203 on the second wall locking 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 self-tightening device 1 tends to move inward, thereby making the first wall locking self-tightening device 1 and the second wall locking self-tightening device 2 tightly locked.

[0032] The installation between adjacent vertical walls 3 and between adjacent top panels 6 is achieved by connecting the corresponding first wall locking self-tightening device 1 and the second wall locking self-tightening device 2 .

[0033] The stress resilience rotating device 5 is used to lock the angle of the vertical fence 3 and disperse the concentrated stress on the vertical fence 3; The top plate 6 is directly fixedly connected to the corresponding first fixing seat 111, and the vertical wall 3 is connected to the corresponding first fixing seat 111 by using a stress rebound rotating device 5; The stress resilience rotating device 5 includes a rotating shaft 505 fixed on the corresponding first fixed seat 111, a cylindrical gear 508 and an upper inclined cylinder 506 sleeved on the rotating shaft 505, two upper and lower sets of limiting connecting sleeves 502 fixed on the side of the vertical wall 3, and a limiting sleeve 504 located between the upper and lower sets of limiting connecting sleeves 502; The rotating shaft 505 is fixedly connected to the corresponding first fixing seat 111 by two sets of fixing rods 503 and a set of lower inclined cylinders 507, and the lower inclined cylinders 507 are located between the two sets of fixing rods 503; The limiting connecting sleeve 502 is sleeved on the rotating shaft 505. Two sets of limiting disks 5051 are provided at the upper and lower parts of the rotating shaft 505. The second spring 501 sleeved on the rotating shaft 505 is located between the limiting connecting sleeve 502 and the limiting disk 5051. The inclined surface at the bottom of the upper inclined cylinder 506 is in close contact with the inclined surface at the top of the lower inclined cylinder 507; An upper tooth seat 5082 is fixed at the bottom of the cylindrical gear 508, and a lower tooth seat 5061 is provided at the top of the upper inclined cylinder 506, and the upper tooth seat 5082 is engaged with the lower tooth seat 5061; The cylindrical gear 508 is engaged with the inner tooth groove 5041 on the inner wall of the limiting sleeve 504 , and the two sets of locking screws 5042 fixed on the limiting 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 limiting sleeve 504 .

[0034] After the first wall locking self-tightening device 1 is connected to the vertical wall 3 through the stress rebound rotating device 5 , the cylindrical gear 508 needs to be lifted upward until it is disengaged from the limiting sleeve 504 .

[0035] Then, the first wall locking self-tightening device 1 is rotated to a fixed position, and the upper inclined cylinder 506 is rotated to ensure that the inclined surface at the top of the lower inclined cylinder 507 and the inclined surface at the bottom of the upper inclined cylinder 506 are parallel and in contact with each other.

[0036] 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 cylinder 506, and use the locking screw 5042 to connect the cylindrical gear 508 and the limiting sleeve 504 to achieve precise control of the angle between adjacent vertical walls 3.

[0037] During use, if the vertical wall 3 or the first wall locking self-tightening device 1 rotates due to improper operation or stress concentration, the lower inclined cylinder 507 will rotate relative to the upper inclined cylinder 506 and the cylindrical gear 508 and lift the cylindrical gear 508.

[0038] However, under the fixed connection of the limiting sleeve 504 to the cylindrical gear 508, the vertical fence 3 will move upward along with the cylindrical gear 508, but under the combined action of gravity and the elastic force of the second spring 501, the vertical fence 3 will drop again and return to its original position, thereby achieving effective resistance to stress concentration.

[0039] The top of the top plate 6 is connected to the outside of the yurt top assembly 8 by an ice expansion self-tightening locking connector 7. The ice expansion self-tightening locking connector 7 ensures that the top plate 6 is firmly connected to the yurt top assembly 8 through its own self-tightening function.

[0040] The outer side of the yurt top assembly 8 is covered with a rubber covering sleeve 11 , and the bottom of the rubber covering sleeve 11 covers and shields the connection between the yurt top assembly 8 and the top plate 6 , that is, the rubber covering sleeve 11 can cover and shield the ice expansion self-tightening locking connector 7 .

[0045] The bottom of the third rotating rod 708 extends into the rear top plate 705 and is fixedly connected to the first bevel gear 711; The first bevel gear 711 is meshed with the second bevel gear 7121 inside the rear top plate 705.

A protruding shift block 7131 is provided at the end of the shift plate 713. The interior of the docking box 709 is equipped with three mechanical lock beams 703 with trapezoidal grooves 7031, and the front top plate 710 is provided with rectangular plug-in slots 7101 for inserting the mechanical lock beams 703; The front top plate 710 and the rear top plate 705 are fixedly connected by three fixed shafts 7146 distributed in a regular triangle, and the fixed shafts 7146 also penetrate a mechanical lock tongue assembly 714 fixed to the inner wall of the front top plate 710; The mechanical bolt assembly 714 includes a bolt rear plate 7141 and a bolt front plate 7142 that fit each other; A first polished rod 7150 at one end of the outer side of the bolt rear plate 7141 passes through a first limiting plate 7149 fixed on the inner wall of the front top plate 710, and a first return spring 7148 is sleeved on the first polished rod 7150. The first return spring 7148 is located between the bolt rear plate 7141 and the first limiting plate 7149; A buckle extension protrusion 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; A lock tongue 7145 and a second light rod 7143 are respectively provided on both sides of the lock tongue front plate 7142. The second light rod 7143 penetrates 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 light rod 7143. The second return spring 7144 is located between the lock tongue front plate 7142 and the second limit plate 7147. 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.

[0046] like Fig. 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); 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. 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.

[0047] like Fig. 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); 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 rightmost limiting slot 71423 on the lock tongue front plate 7142, so that the lock tongue 7145 can be extended. In this way, after the third rotating rod 708 is continuously turned to make the dial plate 713 rotate continuously counterclockwise, the lock tongues 7145 on the three clockwise arranged mechanical lock tongue assemblies 714 can all be extended, and finally the lock tongues 7145 are extended into the trapezoidal groove 7031 of the mechanical lock beam 703.

[0048] When the ice expansion self-tightening locking connector 7 is docked, a salt solution of the same concentration needs to be injected into the cylinder 70221 of the side seat 7022, and then the docking box 709 is pushed to insert the mechanical locking beam 703 into the rectangular plug-in groove 7101 of the front top plate 710, and ensure that the long gear 717 is meshed with the corresponding inner side of the rack plate 704.

[0049] The first rotating rod 706 and the second rotating rod 707 are rotated simultaneously, so that the two sets of long gears 717 are synchronously rotated inside the corresponding rack plates 704, thereby driving the docking box 709 to move toward the direction close to the rear top plate 705.

[0050] When the mechanical lock beam 703 contacts the rear top plate 705, the middle adjusting nut 719 is screwed to extend the threaded screw 718, and the threaded screw rod 718 is rotated around the third pin 721 against the second pawl 716 until the second pawl 716 blocks the second ratchet wheel 715. Then, by screwing the third rotating rod 708, the first bevel gear 711 drives the rotating rod 712 and the dial plate 713 to rotate counterclockwise through the second bevel gear 7121. 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 extended, that is, the locking tongues 7145 extend into the trapezoidal grooves 7031 of the mechanical locking beam 703; Finally, the internal spring 7012 is tightened by rotating the corresponding spring rotating rod 7014 until the first pawl 7016 is clamped on the first ratchet 7015, so that under the elastic force of the spring 7012, the first rotating rod 706 and the second rotating rod 707 have a rotation tendency to self-tighten the ice expansion self-tightening locking connector 7, that is, under the elastic force of the 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, so that the docking box 709 can be driven to move in the direction close to the rear top plate 705, so as to realize the self-tightening effect of the ice expansion self-tightening locking connector 7; During the service process, in an environment where the temperature continues to drop, the ice expansion self-tightening locking connector 7 will become loose due to the thermal expansion and contraction and creep characteristics of the material. A rubber piston head 7023 is installed on the piston shaft 7021 to prevent the salt solution in the cylinder 70221 from leaking. 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 loose docking box 709 and the rear top plate 705 of the ice expansion self-tightening locking connector 7 are tightened, thereby enhancing the stability and safety of the connection between the top plate 6 and the yurt top assembly 8.
