Description

Technical Field

[0001] This invention relates to the field of camping shelter technology, and specifically proposes a retractable camping shelter. Background Technology

[0002] Retractable camping houses are container-style homes convenient for temporary outdoor use. They can be retracted for transport and expanded for use, combining convenient transportation with spaciousness. They are suitable for high-end tourism camping, construction site accommodation, commercial and emergency use, and other special purposes. Common retractable camping houses mainly include lateral retractable and extendable types and lift-and-expandable types. In this invention, the term "retractable camping house" specifically refers to the lift-and-expandable type, which needs to be raised and extended for use. When retractable camping houses are used in field environments such as oil and gas extraction construction, mining exploration and development, and ecological environment monitoring, the working environment is usually remote and harsh. As temporary residences and workplaces for workers, the safety and stability of the camping houses must be guaranteed. Although retractable camping houses have the advantages of convenience and space, they also have many drawbacks.

[0003] (1) When the camping house has completed the upward expansion adjustment, the overlap between the telescopic section and the fixed section is minimal, which greatly reduces the connection strength and stability at the overlap section.

[0004] (2) The existing camping houses have a basic integral structure for the wall panels of the telescopic section. After the height adjustment, the windward area is greatly increased. When there are strong winds or other severe weather in the wild, the wall surface, especially the telescopic connection, is prone to deformation. The wind resistance and deformation resistance are insufficient. After deformation, the lifting and contraction are prone to jamming, which increases the probability of mechanical failure.

[0005] (3) The sealing of the expansion joint is mainly guaranteed by the installation accuracy of the structure. However, when the joint is deformed, the sealing will be further reduced, increasing the probability of wind, rain and dust intrusion. The insulation, sound insulation, moisture resistance and privacy are all reduced, affecting the comfort of temporary residence. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a retractable camping shelter, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention employs the following technical solution: a retractable camping hut, comprising a floor, multiple column assemblies, multiple wall panel assemblies, and a roof panel; the multiple column assemblies are arranged in two rows on the floor; each column assembly includes a fixed column that is vertically fixed to the floor and has a tubular structure, a telescopic column that is slidably installed in the fixed column, and a damping box that is fixed to the bottom end of the fixed column; a locking frame that is fixed in the inner cavity of the fixed column; a telescopic rod that extends and retracts synchronously with the telescopic column is vertically rotatably installed between the bottom end of the telescopic column and the damping box, and multiple locking blocks that cooperate with the locking frame are vertically distributed and fixed on the telescopic section of the telescopic rod; by rotating the telescopic rod, the telescopic column extends and retracts vertically... The system switches between locking and unlocking states in the vertical direction. When locked, the locking block elastically presses against the locking frame in the horizontal direction. Multiple wall panel assemblies are respectively assembled between adjacent column assemblies in each column and between column assemblies at corresponding ends in two columns. The wall panel assembly is a two-section telescopic structure that telescopically extends and retracts synchronously with the telescopic column. There is also a top plate. The top of the telescopic column is detachably equipped with a locking device that horizontally presses the top plate onto the top of the telescopic column. The top of the wall panel assembly is inserted into the bottom of the top plate, and the top plate, locking device, and wall panel assembly are in elastic contact in the horizontal direction. When the top plate rises to the highest position, the telescopic column is in elastic contact with the fixed column around its perimeter.

[0008] Preferably, the wall panel assembly includes a fixed wall panel with its bottom fixed to the floor and both ends fixed between two adjacent fixed columns. A telescopic wall panel is vertically slidably installed in the fixed wall panel. Both ends of the telescopic wall panel are movably inserted between two adjacent telescopic columns. A flexible elastic band connects the telescopic wall panel and the fixed wall panel. Flexible edge bands are fixed between both ends of the telescopic wall panel and the two telescopic columns.

[0009] Preferably, the locking frame includes multiple vertically arranged connecting rods and multiple locking sleeves that are fixed together on the multiple connecting rods. The multiple locking sleeves are vertically and evenly distributed and fixed on the fixed column, and the spacing between the locking sleeves and the locking blocks is equal. When the locking block is clamped in the locking sleeve, the telescopic column is locked in the vertical direction.

[0010] Preferably, the locking sleeve has a horizontally circular locking cavity, and a cross hole coaxial with the locking cavity is vertically opened through the locking sleeve; the telescopic rod passes vertically through the center of the cross holes on the multiple locking sleeves; the locking block includes a patterned sleeve fitted on the telescopic section of the telescopic rod, and four damping contacts are evenly distributed circumferentially and slidably arranged radially on the patterned sleeve, and the damping contacts are elastically connected to the patterned sleeve; by rotating the telescopic rod, when the four damping contacts on the locking block are aligned with the cross holes, the locking block can pass vertically through the cross holes, and the locking is released; when the damping contacts are located in the locking cavity, the upper and lower ends of the locking block are in contact with the upper and lower ends of the locking cavity, and the damping contacts are elastically pressed against the side wall of the locking cavity.

[0011] Preferably, the damping box includes a box body fixed to the bottom of the fixed column and a damping sleeve embedded and fixed in the box body, and a seated bearing is vertically embedded and fixed in the damping sleeve; the telescopic rod includes a rotating shaft and a sliding sleeve rod slidably mounted on the rotating shaft, the rotating shaft vertically passes through the box body and is rotatably mounted on the seated bearing, and the sliding sleeve rod is rotatably mounted on the bottom of the telescopic column; multiple locking blocks are fitted onto the sliding sleeve rod through a flower-shaped sleeve.

[0012] Preferably, elastic bands are connected between the two sides of the telescopic wall panel and the fixed wall panel; the lower end of the elastic band is fixed to the fixed wall panel, and a sliding strip is horizontally fixed to the upper end of the elastic band, with the sliding strip vertically sliding on the wall surface of the telescopic wall panel.

[0013] Preferably, both ends of the telescopic wall panel are provided with multiple vertically distributed side plugs, and the side wall of the telescopic column is provided with multiple insertion holes for the multiple side plugs at one end of the telescopic wall panel to be horizontally inserted in a one-to-one correspondence; the upper and lower ends of the side plugs abut against the insertion holes, and the insertion holes are provided with gaps between the side plugs in the insertion depth direction and on both sides of the side plugs.

[0014] Preferably, the damping contact includes a sliding block that slides with the patterned sleeve, a spring connecting the sliding block and the patterned sleeve, and a roller rotatably mounted on the sliding block via a vertical shaft, the roller being able to abut against the side wall of the locking cavity.

[0015] Preferably, the locking component includes a shaft threadedly installed at the top of the telescopic column and a pressure plate located at the top of the shaft. The shaft passes through the top plate, and a flexible sleeve that elastically contacts the top plate is fitted on the shaft. A plurality of balls are movably embedded in the lower end face of the pressure plate and roll in contact with the top of the top plate.

[0016] The above technical solution has the following advantages or beneficial effects: This invention provides a telescopic camping hut, which adopts a multi-module combination design consisting of a floor, column assembly, wall panel assembly, and roof panel, etc., which can facilitate quick assembly and daily maintenance; the column assembly, as the main support structure for lifting and adjustment, has a built-in locking structure composed of a locking frame, telescopic rod, and locking block on the basis of the basic telescopic structure. On the one hand, the locking can ensure the stability and safety of the camping hut's lifting structure and avoid the risk of accidental descent of the lifting section. On the other hand, through the multi-layer locking cooperation between the locking block and the locking sleeve, a multi-level support is formed in the vertical direction, which makes up for the shortcomings of existing camping huts after lifting and adjustment. The short overlapping connection between the telescopic and fixed sections, which previously reduced structural strength and stability, has been addressed by this design, further enhancing the strength and safety of the camping shelter during use. Furthermore, the column assembly and wall panel assembly constitute a flexible connection between the telescopic and fixed sections, as well as a flexible assembly structure within the telescopic section. The column assembly also integrates a damping and vibration-reducing structure that works in conjunction with the locking mechanism. This dampens and absorbs the impact of strong winds and suppresses and weakens the vibration caused by wind impacts. By ensuring airtightness at the movable connections, the overall wind resistance of the camping shelter is improved, structural deformation is suppressed, the probability of mechanical failure is reduced, and the safety and comfort of the camping shelter during outdoor use are enhanced.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a retractable camping hut is constructed with a square box-like structure. The retractable design allows for easier transport, especially when navigating height-restricted areas, and also allows for expansion of the interior space during camping. The hut includes a floor 1 with multiple feet 11 welded to its bottom surface to elevate the floor 1 horizontally. When used outdoors, a relatively flat surface is found, and cement blocks are placed on it, with the blocks aligned to a uniform level. The feet 11 can be directly anchored to the cement blocks, which have pre-drilled locking points for securing the feet 11. Two rows of upright column assemblies 2 are fixed on the floor 1. In this embodiment, each row contains four upright column assemblies 2, and the four upright column assemblies 2 are evenly spaced. Wall panel assemblies 3 are assembled between adjacent upright column assemblies 2 in each row and between the upright column assemblies 2 at corresponding ends in the two rows, for a total of eight wall panel assemblies 3. The upright column assemblies 2 and wall panel assemblies 3 are assembled together to form a rectangular frame-type camping cabin wall structure. It should be noted that in this embodiment, the six wall panel assemblies 3 in the two rows have the same width, the two wall panel assemblies 3 located between the two rows have the same width, and the width of the wall panel assemblies 3 located between the two rows is larger than the width of the other six wall panel assemblies 3, but the eight wall panel assemblies 3 have the same structure and are not distinguished by size. A top plate 4 is horizontally encapsulated at the top of all the upright column assemblies 2 and wall panel assemblies 3.

[0038] like Figure 6 , Figure 7 and Figure 10As shown, the column assembly 2 includes a fixed column 21 that is vertically fixed to the floor 1 by bolts. The fixed column 21 is a square tubular structure. A telescopic column 22 is slidably installed in the fixed column 21. The telescopic column 22 is a square rod structure. A buffer sleeve 221 is fitted on a section of the telescopic column 22 adjacent to the bottom end. The buffer sleeve 221 is aligned with the side wall of the telescopic column 22. A bearing plate 222 is fixed to the bottom end of the telescopic column 22 by bolts. The bearing plate 222 contacts the buffer sleeve 221 to prevent the buffer sleeve 221 from falling off the telescopic column 22. A damping box 23 is assembled at the bottom of the fixed column 21. The damping box 23 includes a box body 231 fixed to the bottom of the fixed column 21 by bolts and a damping sleeve 232 embedded in the box body 231. The box body 231 has a square bucket structure and is embedded through the floor 1. The damping sleeve 232 is made of rubber. A seated bearing 234 is vertically embedded in the damping sleeve 232. The seated bearing 234 is further fixed to the damping sleeve 232 by bolts. In order to improve the actual damping effect of the damping sleeve 232, multiple fin slots 233 are evenly distributed in the circumferential direction in the groove of the damping sleeve 232. Multiple fins 235 are distributed in the circumferential direction on the outer side wall of the seated bearing 234 and are embedded in the multiple fin slots 233.

[0039] like Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 11 A telescopic rod 26, which extends and retracts synchronously with the telescopic column 22, is vertically rotatably mounted between the bottom end of the telescopic column 22 and the damping box 23. The telescopic rod 26 includes a rotating shaft 261 and a sliding sleeve rod 262. The rotating shaft 261 is rotatably mounted on a bearing 234 and passes downward through the box 231. A movable gap is reserved between the rotating shaft 261 and the through hole at the bottom of the box 231. In this embodiment, a handwheel for easy rotation is also welded to the bottom end of the rotating shaft 261. The sliding sleeve rod 262 is slidably fitted onto the rotating shaft 261 via a key, and is rotatably mounted on the bearing plate 222 via a bearing. A locking frame 24 is installed in the inner cavity of the fixed column 21. The locking frame 24 includes ten vertically and equally spaced locking sleeves 25 and four connecting rods 241. The locking sleeves 25 are generally square in shape. The four corners of each locking sleeve 25 are welded to the four connecting rods 241 one by one. The four connecting rods 241 connect the ten locking sleeves 25 in sequence. The four connecting rods 241 extend downward into the box body 231 and are fixedly connected to the bottom of the box body 231 by bolts. The locking sleeves 25 are embedded and close to the inner cavity of the fixed column 21 and are further fixed to the fixed column 21 by bolts.

[0040] like Figure 8 , Figure 12 and Figure 13As shown, five locking blocks 27 are evenly distributed and fixed along the upper edge of the sliding sleeve 262. The locking blocks 27 cooperate with the locking sleeve 25 and the two are evenly spaced. A circular locking cavity 251 is horizontally provided in the locking sleeve 25. A cross hole 252 coaxial with the locking cavity 251 is vertically opened through the locking sleeve 25, and the edge of the cross hole 252 away from the center coincides with the edge of the locking cavity 251. The telescopic rod 26 passes vertically through the center of the cross hole 252 on the ten locking sleeves 25. The locking block 27 includes a flower-shaped sleeve 271 welded onto the sliding sleeve rod 262. The flower-shaped sleeve 271 has four guide blocks 272 evenly distributed circumferentially. Each of the four guide blocks 272 is equipped with a damping contact 273. The damping contact 273 includes a sliding block 274 that is slidably mounted on the guide block 272 along the radial direction of the flower-shaped sleeve 271. A spring 275 is welded between the sliding block 274 and the guide block 272, and a roller 276 is rotatably mounted on the sliding block 274 via a vertical shaft.

[0041] In this embodiment, the upper and lower end faces of the sliding block 274 and the flower-shaped sleeve 271 are flush. When the damping contact 273 is located in the locking cavity 251, the upper and lower ends of the locking block 27 are in contact with the upper and lower ends inside the locking cavity 251. The locking block 27 is clamped in the locking cavity 251, restricting the freedom of the sliding sleeve rod 262 to slide up and down, so that the telescopic column 22 is locked in the vertical direction. In the locked state, the five locking blocks 27 are located one-to-one in the locking cavities 251 of the five consecutively distributed locking sleeves 25. This design allows the telescopic column 22 and the fixed column 21 to form a multi-level indirect support in the vertical direction through the locking engagement of the locking block 27 and the locking sleeve 25. Especially when the telescopic column 22 extends upward to its maximum height, it compensates for the shortest overlapping section between the telescopic column 22 and the fixed column 21, which resulted in low structural strength and poor stability. This ensures the overall strength of the column assembly 2 in the vertical direction, greatly reducing the risk of accidental descent of the telescopic section of the campsite roof and improving overall safety. Furthermore, when in the locked state, under the elastic force of the spring 275, the roller 276 elastically presses against the inner wall of the locking cavity 251. Turning the handwheel drives the rotating shaft 261 to rotate 90 degrees. The sliding rod 262 rotates synchronously with the rotating shaft 261, aligning the four damping contacts 273 on the locking block 27 with the cross hole 252. At this time, the locking block 27 rotates out of the locking cavity 251, releasing the lock. The locking block 27 can also pass vertically through the cross hole 252, allowing the telescopic column 22 and the sliding rod 262 to slide freely up and down, enabling height adjustment of the camping cabin. The corresponding locking and unlocking positions can be marked at the bottom of the housing 231 to guide the handwheel rotation operation.

[0042] like Figure 1 , Figure 3 and Figure 6As shown, the wall panel assembly 3 includes a fixed wall panel 31 whose bottom is fixed to the floor 1 by bolts and whose two ends are fixed between two adjacent fixed columns 21; two reinforcing plates 211 are integrally formed on each of the four side walls of the fixed columns 21. The thickness of the fixed wall panel 31 is slightly less than the width of the two reinforcing plates 211. The reinforcing plates 211 serve as reinforcing ribs to improve the structural strength of the fixed columns 21. On the other hand, one end of the fixed wall panel 31 can be vertically inserted between the two reinforcing plates 211 for quick positioning and installation. The fixed wall panel 31 can be further locked and fixed to the reinforcing plates 211 by bolts. The fixed wall panel 31 has an inner cavity 311 from the top downwards. The inner cavity 311 is an open structure at both ends of the fixed wall panel 31. The space below the inner cavity 311 in the fixed wall panel 31 can be filled with thermal insulation materials such as polyurethane foam.

[0043] like Figure 1 , Figure 3 , Figure 6 , Figure 9 and Figure 15 As shown, a telescopic wall panel 32 is vertically slidably installed in the inner cavity 311 of the fixed wall panel 31. Multiple vertically evenly distributed side plugs 321 are provided at both ends of the telescopic wall panel 32. Multiple insertion holes 223 are provided on the side wall of the telescopic column 22 for horizontal insertion of the multiple side plugs 321 at one end of the telescopic wall panel 32. It should be noted that the side wall on the telescopic column 22 where the insertion holes 223 are to be provided depends on whether it is installed and fitted with the telescopic wall panel 32. Therefore, in each column assembly 2, the insertion holes 223 on the telescopic columns 22 at both ends of a column are located on two adjacent side walls, while the insertion holes 223 on the telescopic columns 22 between the two ends of a column are located on two opposite side walls. In addition, the side wall of the fixed column 21 is provided with a clearance opening 212 to avoid the sliding of the telescopic wall panel 32. The principle of the clearance opening 212 and the insertion hole 223 is related to this principle. The side plug 321 is aligned with the upper and lower ends of the socket 223, which keeps the telescopic wall panel 32 and the telescopic column 22 relatively fixed in the vertical direction. The socket 223 has gaps between itself and the side plug 321 in the insertion depth direction and on both sides of the horizontal position, so that the telescopic wall panel 32 and the telescopic column 22 have relative displacement space in the horizontal direction, avoiding rigid connection of multiple telescopic columns 22 by multiple telescopic wall panels 32. Both ends of the telescopic wall panel 32 are covered with rubber edge sleeves 34, and the side plugs 321 pass through the edge sleeves 34. The edge sleeves 34 are fixed to the telescopic wall panel 32 and the telescopic column 22 by gluing and screw fastening, so that the telescopic wall panel 32 and the telescopic column 22 form a flexible connection while retaining horizontal displacement space, and achieve a sealing effect at the connection.

[0044] like Figure 3 and Figure 4As shown, elastic bands 33 made of rubber are connected between the two sides of the telescopic wall panel 32 and the fixed wall panel 31. The lower end of the elastic band 33 is glued and fixed to the wall surface of the fixed wall panel 31 and reinforced by screws. A sliding strip 331 is horizontally fixed to the upper end of the elastic band 33. The sliding strip 331 is embedded in the elastic band 33. In order to improve the overall toughness of the elastic band 33 and delay its elastic fatigue failure, multiple elastic steel wires (not shown in the figure) can be welded horizontally and evenly on the sliding strip 331. The elastic steel wires can be embedded in the elastic band 33 as an internal skeleton. Both sides of the telescopic wall panel 32 have elastic bands 33. Multiple horizontally evenly distributed sliding grooves 323 are provided along the wall surface. The sliding grooves 323 extend vertically downward from the top of the telescopic wall panel 32. The sliding strip 331 is slidably installed in the multiple sliding grooves 323 on the same side of the wall surface of the telescopic wall panel 32, and the sliding strip 331 is in close contact with the wall surface. In addition, in order to prevent the sliding strip 331 from detaching from the sliding groove 323, the lower end of the sliding groove 323 is closed. The flexible connection between the telescopic wall panel 32 and the fixed wall panel 31 is realized by two elastic bands 33, which also constitute a seal at the connection. In order to further improve the sealing effect, the two ends of the elastic bands 33 can also be in close contact with the side wall of the telescopic column 22.

[0045] like Figure 3 , Figure 14 and Figure 16 As shown, a capping frame 41 is welded to the bottom of the top plate 4. The capping frame 41 consists of eight round hole sleeves 411 corresponding to the eight column assemblies 2 and eight square frames 412 corresponding to the eight wall panel assemblies 3. The eight round hole sleeves 411 and the eight square frames 412 are connected alternately to form a rectangular capping frame 41. The top of the telescopic wall panel 32 is provided with a top insert plate 322 that is inserted into the corresponding square frame 412. A flexible rubber sleeve that can wrap around the top insert plate 322 is embedded and fixed in the square frame 412. The flexible rubber sleeve ensures the sealing of the insertion joint and can be flexibly deformed, so that a certain range of freedom of movement is reserved between the top insert plate 322 and the square frame 412. The top of the telescopic column 22 is detachably installed with a locking member 28 that presses the top plate 4 horizontally and installs it on the top of the telescopic column 22.

[0046] like Figure 3 and Figure 14As shown, the locking component 28 includes a shaft 281 that passes vertically through the corresponding round hole sleeve 411 and is threadedly installed on the top of the telescopic column 22. A pressure plate 282 is provided at the top of the shaft 281, and a flexible sleeve 284 is fitted onto the shaft 281, which elastically contacts the inner wall of the round hole sleeve 411. Here, the flexible sleeve 284 serves the same function as the flexible rubber sleeve inside the square frame 412, and will not be described further. Multiple balls 283 are movably embedded on the lower end face of the pressure plate 282, making rolling contact with the top of the top plate 4. The ball bearings 283 are evenly distributed around the center of the pressure plate 282. It should be noted that the locking element 28 acts like a bolt to fix the top plate 4. On the one hand, the pressure plate 282 presses the top plate 4 against the top of the telescopic column 22 with the help of the ball bearings 283, preventing the top plate 4 from moving in the vertical direction. On the other hand, the top plate 4, the telescopic column 22, and the telescopic wall surface retain a degree of freedom of movement within the horizontal range, while the ball bearings 283 reduce the friction of the pressing contact and prevent over-locking.

[0047] It should be added that a corresponding lifting drive device can be installed on the floor 1. The lifting drive device is not shown in the attached drawing. For example, an electric hydraulic cylinder can be selected as the drive device. The electric hydraulic cylinder is vertically fixed on the floor 1, and the output rod of the electric hydraulic cylinder can be movably installed on the top plate 4. A limiting sleeve can be installed on the top plate 4, and the output rod of the electric hydraulic cylinder can fix a disc. The disc is assembled in the limiting sleeve. The disc cannot move up and down in the limiting sleeve, but can move within a certain range in the horizontal direction. Other existing lifting equipment can also be selected, as long as the lifting connection end is provided with a certain range of movement in the horizontal direction. In addition, doors and windows can be opened and installed on the fixed wall panel 31.

[0048] When the camping hut is fully retracted, the telescopic column 22 is located inside the fixed column 21, and there is rigid contact between the telescopic column 22 and the fixed column 21. The telescopic wall panel 32 is located in the inner cavity 311 of the fixed wall panel 31, and there is also rigid contact. In addition, the five locking blocks 27 are located one-to-one in the five locking sleeves 25 distributed from bottom to top, and the column assembly 2 is in the locked state.

[0049] When in use, the camping cabin needs to be fully raised and unfolded. Specifically, first turn the eight handwheels in sequence to the unlock position, so that the locking block 27 and the locking sleeve 25 are unlocked. Then, the lifting drive device drives the top plate 4 to rise vertically. The top plate 4 then drives the telescopic column 22 to extend upward from the fixed column 21 through the locking member 28. The telescopic column 22 indirectly drives the telescopic wall panel 32 to extend from the fixed wall panel 31, thereby completing the raising and unfolding adjustment.

[0050] In this invention, when the top plate 4 rises to its highest position, the telescopic column 22 maintains elastic contact with the fixed column 21 through the buffer sleeve 221. The bottom of the telescopic wall panel 32 disengages from the inner cavity 311, and the telescopic wall panel 32 and the fixed wall panel 31 are in non-rigid contact. It should be noted that, to facilitate subsequent resetting, the bottom end of the telescopic wall panel 32 can be chamfered, or the bottom structure of the telescopic wall panel 32 can be improved by providing an insert plate structure similar to the top end at the bottom end of the telescopic wall panel 32, and wrapping the bottom insert plate structure with a rubber layer. When the top plate 4 is in its highest position, the bottom insert plate is inserted into the inner cavity 311, and the rubber layer contacts the inner wall of the inner cavity 311, thereby improving the connection strength between the telescopic wall panel 32 and the fixed wall panel 31, and also improving the sealing performance. In addition, when the top plate 4 is in its highest position, the five locking blocks 27 rise with the telescopic column 22 to a position that aligns with the five locking sleeves 25 from top to bottom. After the adjustment is completed, the eight handwheels can be rotated in sequence to lock the locking position, so that the locking blocks 27 rotate and extend into the locking cavity 251 of the locking sleeve 25.

[0051] This invention provides a retractable camping hut that improves the structural design of existing camping huts, fundamentally enhancing their wind and deformation resistance while maintaining airtightness. This improves overall strength and safety, and enhances the comfort of temporary accommodation. Specifically, this is reflected in the following aspects:

[0052] (1) The camping house consists of four major modules: floor 1, column assembly 2, wall panel assembly 3 and roof 4. The column assembly 2 can be pre-assembled, and the wall panel assembly 3 can be quickly assembled with the column assembly 2. The standardized and modular design not only meets the needs of rapid assembly, but also facilitates the quick disassembly and replacement of certain module structures, making maintenance and repair convenient.

[0053] (2) The column assembly 2 serves as the main support structure for the lifting and adjustment. Its main body consists of a fixed column 21 and a telescopic column 22 that are telescopically coordinated. However, it is equipped with a locking structure composed of a locking frame 24, a telescopic rod 26, and a locking block 27. On the one hand, the column can be locked after the lifting adjustment to ensure the stability and safety of the camping house lifting structure and avoid the risk of the camping house lifting section falling unexpectedly. On the other hand, after locking is completed, the locking cooperation between multiple locking blocks 27 and multiple locking sleeves 25 forms a multi-level support in the vertical direction, which makes up for the problem of reduced structural strength and stability caused by the short overlapping connection between the telescopic section and the fixed section after the existing camping house is lifted and adjusted. This improves the strength and safety of the camping house during use.

[0054] (3) In the camping structure provided by the present invention, the fixed column 21 and the fixed wall panel 31 are rigidly fixedly connected in sequence and are jointly fixed on the floor 1, thus forming a fixed section structure with rigid assembly connection; the telescopic column 22 and the telescopic wall panel 32 are movably inserted and further flexibly connected by the edge sleeve 34, thus forming a telescopic section structure with non-rigid assembly connection; when the camping structure is in use, the telescopic column 22 and the fixed column 21 are in contact through the buffer sleeve 221, while the telescopic wall panel 32 and the fixed wall panel 31 are connected by the elastic band 33, so that the telescopic section and the fixed section form a fixed section structure with rigid assembly connection. The top plate 4 and the top of the telescopic section are also non-rigid connections. In addition, in the structure of the column assembly 2, the locking block 27 maintains elastic contact with the locking cavity 251 of the locking sleeve 25 through the ball bearing 283, and the damping box 23 is equipped with a damping sleeve 232. Therefore, when subjected to impacts such as strong winds, the telescopic wall panel 32 will actively withstand the impact from the wind force, and the edge sleeve 34 and elastic band 33 will dampen and consume the wind force. Consequently, the column assembly 2 will also dampen and consume the impact, jointly suppressing the impact vibration, thereby reducing the deformation and damage to the camping house structure caused by wind impact and improving wind resistance and deformation resistance.

[0055] (4) The telescopic column 22 and the fixed column 21 are sealed by a buffer sleeve 221, the telescopic wall panel 32 and the fixed wall panel 31 are sealed by an elastic band 33, the telescopic wall panel 32 and the telescopic column 22 are sealed by an edge sleeve 34, and the top plate 4 and the telescopic wall panel 32 and the column assembly 2 are also sealed by a buffer sealing design. At the same time, the above elastic damping structure design also greatly reduces the deformation of the room structure and reduces the possibility of increasing the sealing gap due to structural deformation. Therefore, the sealing performance of the movable connection is taken into account, and the sealing effect is guaranteed.
