Description

Technical Field

[0001] This invention relates to the field of tent technology, specifically to an expandable tent frame structure and unit tent. Background Technology

[0002] Tent frame structures typically refer to a simple and common building structure, often used for erecting tents, awnings, outdoor event spaces, temporary buildings, and agricultural purposes. Among them, modular tents are a type of building that combines tent structures with modular design. They integrate the characteristics of traditional tents with modern modular building technology to create a flexible, mobile, and quick-to-assemble building solution suitable for temporary or permanent uses.

[0003] A search revealed that utility model patent number "CN111119566A" provides "a tent frame, a unit tent, and an extendable cubic tent. The tent frame is assembled from multiple unit tents sharing a common edge structure. Each unit tent consists of an inflatable tarpaulin and a tent frame. The tent frame includes a base, columns, and beams. The beams have at least a first water trough and a second water trough along their length. The first water trough is located on the upper surface of the beam, with fabric top slots on both sides. The second water trough is located inside the beam and below the first water trough, with several drainage holes spaced apart on the bottom surface of the first water trough. A third water trough is located inside the column along its length, with the ports of the first and second water troughs connected to the port of the third water trough. This invention simplifies the structure of the columns and beams, making it more suitable for handling large volumes of water. It also reduces the assembly of small parts, improves structural stability, and allows the overall frame to retain its concealed drainage function while significantly reducing structural weight." However, the structure of each individual tent is relatively fixed, and the tent space cannot be expanded or reduced at any time according to actual usage needs, resulting in low applicability. In addition, the tent can be used in a variety of environments. When the ground is uneven or on a slope, the slope may cause the tent to be unusable or tilted after installation. The tilted tent structure is unstable and may tip over, resulting in low safety.

[0004] Therefore, we provide a scalable tent frame structure and unit tent. Summary of the Invention

[0018] The technical effects and advantages of this invention are as follows:

[0019] 1. This invention features an extension mechanism. When the tent needs to be expanded, the auxiliary support column is pulled outward. This causes the folding rods one and two to rotate at different angles. Simultaneously, the folding rod one, through a secondary connecting buckle and a connecting block, drives the pulley to slide inside the slide rail seat two. The extension distance can be adjusted according to the expansion requirements. As the auxiliary support column is extended, the connecting beam extends outward through the connecting piece. The connecting beam connects with the crossbeam frame. When the auxiliary support column is unfolded, it works in conjunction with the connecting beam to stabilize the structure. After unfolding, bolt one is loosened, and the extension column is pulled downward until the support pad at the lower end of the extension column is in contact with the ground. Then, bolt one is tightened. The unfolded auxiliary support column provides support through the extension column, making the expanded tent structure more stable. The tent space can be expanded or reduced according to actual conditions, making it more versatile.

[0020] 2. By setting up height and angle adjustment components, the overall height of the tent can be adjusted according to actual installation needs during installation. Insert the adjustment rod into the through hole, then apply rotational force to the rod. The rod drives the adjustment seat to rotate through the through hole, and the adjustment seat drives the coarse threaded rod to rotate and rise within the threaded groove. When the adjustment rod rotates from one side to the other, it will be blocked by the guide rail. At this time, simply insert the adjustment rod from the other side of the through hole to continue rotating. As the coarse threaded rod rotates, the secondary support column moves up and down. During this process, the slider on one side of the secondary support column slides within the guide rail. The guide rail restricts the position of the slider within the guide rail, allowing it to move only in a straight line along the guide rail trajectory, preventing the secondary support column from rotating along with the adjustment seat. When the installation location is uneven or on a slope, the angle between the tent and the base can be changed by adjusting the angle of the connecting seat. Manually rotate the knob, which drives the short threaded rod to rotate. The short threaded rod and the support buckle rotate, causing the mating tooth seat to move outward. As the mating tooth seat moves, the guide block slides in the guide groove, preventing the mating tooth seat from rotating along with the short threaded rod. Adjust the tilt angle of the connecting seat according to the slope. After adjustment, rotate the short threaded rod, and the mating tooth seat and the limiting tooth seat will mesh to fix the adjusted connecting seat and the base. The tilted base can fit snugly with the slope, ensuring that the center of gravity of the tent always remains vertically downward. The installed tent is more stable and will not be affected by the ground slope. Attached Figure Description

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.

[0037] Example 1

[0038] according to Figure 1-5 and Figure 9-13 The expandable tent frame structure and unit tent shown include a main support column 1, an extension mechanism 2, a connector 5, a crossbeam 6, and a top frame 7. The upper end of the main support column 1 is provided with a groove 11, and the lower end of the main support column 1 is welded with a locking pin seat 12. An extension mechanism 2 is installed on one side of the main support column 1. A connector 5 is installed on the upper end of the main support column 1. A crossbeam 6 is installed on the upper end of the connector 5. A top frame 7 is installed on the upper end of the crossbeam 6.

[0039] The extension mechanism 2 includes a folding member 21, an auxiliary support member 22, and a connector 23. The folding member 21 is installed on one side of the main support column 1, the auxiliary support member 22 is installed on the other side of the folding member 21, and the connector 23 is installed on the upper end of the auxiliary support member 22.

[0040] The connector 5 includes a corner connector 51 and a middle connector 52. The corner connector 51 is installed at the upper end of the main support column 1, and the middle connector 52 can also be installed at the upper end of the main support column 1.

[0041] Specifically, the folding component 21 includes a main connecting buckle 211, a slide rail seat 1 212, a folding rod 1 213, a secondary connecting buckle 214, a connecting block 215, a pulley 216, a slide rail seat 217, and a folding rod 218. The main connecting buckle 211 is welded to one side of the main support column 1. The slide rail seat 1 212 is welded to the lower end of the main connecting buckle 211. The folding rod 1 213 is rotatably mounted on one side of the main connecting buckle 211. The secondary connecting buckle 214 is rotatably mounted on the other end of the folding rod 1 213. A connecting block 215 is welded to the other side of the secondary connecting buckle 214. Pulleys 216 are rotatably mounted on both sides of the connecting block 215 via short shafts. The outer side of the pulleys 216 slides... The tent is equipped with a second slide rail seat 217. A second folding rod 218 is rotatably mounted on the upper end of the slide rail seat 217 via a connecting buckle. The other end of the second folding rod 218 is slidably connected to the first slide rail seat 212. The second folding rod 218 and the first folding rod 213 are rotatably connected by a shaft. When the tent needs to be expanded, the auxiliary support column 221 is pulled outward. The auxiliary support column 221 causes the first folding rod 213 and the second folding rod 218 to rotate at different angles. At the same time, the first folding rod 213 drives the pulley 216 to slide inside the second slide rail seat 217 through the secondary connecting buckle 214 and the connecting block 215. The distance pulled out can be adjusted according to the expansion needs.

[0042] Specifically, the auxiliary support component 22 includes an auxiliary support column 221, bolt 222, extension column 223, and support pad 224. The auxiliary support column 221 is welded to the other side of the slide rail seat 217, and the connector 23 is bolted to the upper end of the auxiliary support column 221. Bolt 222 is threaded on both sides of the auxiliary support column 221. The extension column 223 is slidably installed inside the auxiliary support column 221. The support pad 224 is installed at the lower end of the extension column 223. After unfolding, the bolt 222 is unscrewed, and the extension column 223 is pulled down until the support pad 224 at the lower end of the extension column 223 is in contact with the ground. Then the bolt 222 is tightened. The unfolded auxiliary support column 221 provides support through the extension column 223, making the expanded tent structure more stable.

[0043] Specifically, the corner connector 51 includes a locking pin 511 and a placement seat 512. The locking pin 511 is bolted inside the groove 11. The placement seat 512 is welded to the upper end of the locking pin 511. The placement seat 512 includes a crossbeam placement seat 5121 and a side beam placement seat 5122. The crossbeam placement seat 5121 is welded to one side of the upper end of the locking pin 511, and the side beam placement seat 5122 is welded to the other side of the upper end of the locking pin 511. The intermediate connector 52 is provided with two sets of side beam placement seats 5122. The corner connector 51 or the intermediate connector 52 can be selected to be installed according to the installation situation. The intermediate connector 52 is used to connect the two sets of side beams 8 and crossbeams 6 in the middle position of the tent structure. The corner connector 51 is used to connect the side beams 8 and crossbeams 6 at the corner position of the tent structure.

[0044] Specifically, the crossbeam 6 includes a crossbeam frame 61 and a connecting beam 62. The crossbeam frame 61 is bolted to the upper end of the crossbeam placement seat 5121. A limit block 611 is welded to the lower end of the crossbeam frame 61. The connecting beam 62 is slidably installed inside the crossbeam frame 61, and the other end of the connecting beam 62 is bolted to the connecting piece 23. The distance of the pull-out can be adjusted according to the expansion requirements. When the auxiliary support column 221 is pulled out, the connecting beam 62 is driven to extend outward through the connecting piece 23. The connecting beam 62 is connected to the crossbeam frame 61. When the auxiliary support column 221 is unfolded, it cooperates with the connecting beam 62 to play a role in structural stability.

[0045] Specifically, the top frame 7 includes a fixed adjustment seat 71, bolt 72, connecting rod 73, and intermediate fixing buckle 74. The fixed adjustment seat 71 is movably installed on the outer side of the crossbeam frame 61. The upper end of the fixed adjustment seat 71 has a limit groove 711, and the limit groove 711 and the limit block 611 are slidably connected. Bolt 72 is bolted to both sides of the fixed adjustment seat 71. The connecting rod 73 is rotatably installed on the upper end of the fixed adjustment seat 71 through a shaft. The intermediate fixing buckle 74 is rotatably installed on the other end of the connecting rod 73 through a shaft. The height of the top frame 7 can be adjusted according to the actual installation situation. Loosen the bolt 72, and then adjust the fixed adjustment seats 71 on both sides. The fixed adjustment seat 71 drives the connecting rod 73 to change angle, thereby completing the height adjustment of the top frame 7. After the adjustment is completed, the position of the fixed adjustment seat 71 can be fixed with bolt 72.

[0046] Example 2

[0047] Please see Figure 1-4 and Figure 6-7As shown, in another embodiment of the present invention, a height adjustment assembly 3 is installed at the lower end of the main support column 1. The height adjustment assembly 3 includes a secondary support column 31, a coarse threaded rod 32, an adjustment seat 33, an adjustment rod 34, a fixed seat 35, a guide rail 36, and a second locking pin seat 37. The secondary support column 31 is bolted to the lower end of the first locking pin seat 12. A slider 311 is welded to one side of the secondary support column 31. A threaded groove 312 is opened at the lower end of the secondary support column 31. The coarse threaded rod 32 is installed inside the threaded groove 312. An adjustment seat 33 is welded to the lower end of the coarse threaded rod 32. A through hole 331 is opened through one side of the adjustment seat 33. The adjustment rod 34 is placed inside the through hole 331. A fixed seat 35 is rotatably installed at the lower end of the adjustment seat 33 via a bearing. A guide rail 36 is welded to one side of the fixed seat 35, and the guide rail 36 and the slider 311 are slidably connected. A second locking pin seat 37 is welded to the lower end of the fixed seat 35. During installation, the overall height of the tent can be adjusted according to actual installation needs. The adjusting rod 34 is inserted into the through hole 331, and then the adjusting rod 34 is given rotational force. The adjusting rod 34 drives the adjusting seat 33 to rotate through the through hole 331. The adjusting seat 33 drives the coarse thread rod 32 to rotate and rise and fall in the threaded groove 312. When the adjusting rod 34 rotates from one side to the other side, it will be blocked by the guide rail 36. At this time, simply insert the adjusting rod 34 from the other side of the through hole 331 to rotate. As the coarse thread rod 32 rotates, the secondary support column 31 moves up and down. During this process, the slider 311 on one side of the secondary support column 31 slides in the guide rail 36. The guide rail 36 restricts the position of the slider 311 within the guide rail 36, so that it can only move in a straight line along the trajectory of the guide rail 36, avoiding the situation where the secondary support column 31 rotates when the adjusting seat 33 is rotated.

[0048] Example 3

[0049] Please see Figure 1-4 and Figure 8As shown, in another embodiment of the present invention, an angle adjustment component 4 is installed at the lower end of the height adjustment component 3. The angle adjustment component 4 includes a connecting seat 41, a base 42, and a fixing member 43. The connecting seat 41 is bolted to the lower end of the locking pin 37. A connecting shaft 411 is welded to both sides of the lower end of the connecting seat 41. A limit tooth seat 412 is welded to the other end of the connecting shaft 411. The base 42 is installed at the lower end of the connecting seat 41. The base 42 includes a rotating buckle 421, a base 422, and a support buckle 423. The rotating buckle 421 is rotatably installed on the outer side of the connecting shaft 411. A base 422 is welded to the lower end of the seat 421. Guide grooves 4221 are provided on both sides of the surface of the base 422. A support seat 423 is installed on one side of the rotating seat 421, and the guide grooves 4221 are formed between the rotating seat 421 and the support seat 423. A fixing member 43 is installed inside the support seat 423. The fixing member 43 includes a short threaded rod 431, a knob 432, a mating gear seat 433, and a guide block 434. The short threaded rod 431 is threaded inside the support seat 423. A knob 432 is welded to one end of the short threaded rod 431, and the other end of the short threaded rod 431 passes through... The bearing is rotatably mounted with a mating gear seat 433, which meshes with the limiting gear seat 412. A guide block 434 is welded to the lower end of the mating gear seat 433, and the guide block 434 is slidably connected to the guide groove 4221. When the installation position is uneven or on a slope, the angle between the tent and the base 42 can be changed by adjusting the angle of the connecting seat 41. Manually rotating the knob 432 causes the short threaded rod 431 to rotate. The short threaded rod 431 rotates in conjunction with the support buckle 423, causing the mating gear seat 433 to move outwards. During movement, the guide block 434 slides within the guide groove 4221, preventing the mating gear seat 433 from rotating along with the short threaded rod 431. The tilt angle of the connecting seat 41 is adjusted according to the slope. After adjustment, the short threaded rod 431 is rotated, and the mating gear seat 433 engages with the limiting gear seat 412, thereby fixing the adjusted connecting seat 41 to the base 42. The tilted base 422 can fit snugly with the slope, ensuring that the overall center of gravity of the tent always remains vertically downward. The installed tent is more stable and will not be affected by the ground slope.

[0050] Example 4

The side beam 8 includes a main side beam 81, bolts 82, an extension side beam 83, and a secondary side beam 84. The main side beam 81 is bolted to the upper end of the side beam placement seat 5122. Bolts 82 are threaded on both sides of the main side beam 81. The extension side beam 83 is slidably installed inside the main side beam 81. The secondary side beam 84 is slidably installed on the outer side of the other end of the extension side beam 83. The length of the side beam 8 can be adjusted according to actual needs to expand the tent structure. The bolts 82 are loosened manually, and then the length of the extension side beam 83 extending beyond the main side beam 81 and the secondary side beam 84 is adjusted. After adjustment, the bolts 82 are tightened.

[0052] Example 5

[0053] according to Figure 1-14 The unit tent shown includes a tent structure and a tent cloth 9. The tent structure adopts the tent structure of any one of claims 1-9. The tent cloth 9 is installed on the outside of the tent structure. After the tent structure is erected, the tent cloth 9 is fixedly installed on the outside of the tent structure.

[0054] Working principle of this invention:

[0055] Step 1: When the tent needs to be expanded, pull the auxiliary support column 221 outward. The auxiliary support column 221 drives the first folding rod 213 and the second folding rod 218 to rotate at different angles. At the same time, the first folding rod 213 drives the pulley 216 to slide inside the second slide rail seat 217 through the secondary connecting buckle 214 and the connecting block 215. The distance of pulling out can be adjusted according to the expansion needs. While the auxiliary support column 221 is pulled out, the connecting beam 62 is driven to extend outward through the connector 23. The connecting beam 62 is connected to the crossbeam frame 61. When the auxiliary support column 221 is unfolded, it cooperates with the connecting beam 62 to play a role in stabilizing the structure.

[0056] Step 2: After unfolding, unscrew bolt 222 and pull down extension column 223 until the support pad 224 at the lower end of extension column 223 is in contact with the ground. Then tighten bolt 222. The unfolded auxiliary support column 221 will be supported by extension column 223, making the expanded tent structure more stable.

[0057] Step 3: During installation, the overall height of the tent can be adjusted according to the actual installation requirements. Insert the adjusting rod 34 into the through hole 331, and then apply rotational force to the adjusting rod 34. The adjusting rod 34 drives the adjusting seat 33 to rotate through the through hole 331. The adjusting seat 33 drives the coarse thread rod 32 to rotate and rise and fall in the threaded groove 312. When the adjusting rod 34 rotates from one side to the other side, it will be blocked by the guide rail 36. At this time, simply insert the adjusting rod 34 from the other side of the through hole 331 to rotate. As the coarse thread rod 32 rotates, the secondary support column 31 moves up and down. During this process, the slider 311 on one side of the secondary support column 31 slides in the guide rail 36. The guide rail 36 restricts the position of the slider 311 within the guide rail 36, so that it can only move in a straight line along the trajectory of the guide rail 36, thus avoiding the situation where the secondary support column 31 rotates when the adjusting seat 33 is rotated.

[0058] Step 4: When the installation location is uneven or on a slope, the angle between the tent and the base 42 can be changed by adjusting the angle of the connecting seat 41. Manually rotate the knob 432, which will cause the short threaded rod 431 to rotate. The short threaded rod 431 and the support buckle 423 will rotate together, causing the mating tooth seat 433 to move outward. When the mating tooth seat 433 moves, it will cause the guide block 434 to slide in the guide groove 4221, preventing the mating tooth seat 433 from rotating when the short threaded rod 431 rotates. Adjust the tilt angle of the connecting seat 41 according to the slope. After adjustment, rotate the short threaded rod 431, and the mating tooth seat 433 will mesh with the limiting tooth seat 412 to fix the adjusted connecting seat 41 and the base 42. The tilted base 422 can fit the slope, so that the center of gravity of the tent always remains vertically downward. The installed tent is more stable and will not be affected by the ground slope.

[0059] Step 5: Adjust the height of the top frame 7 according to the actual installation situation. Loosen bolt 2 72, and then adjust the fixed adjustment seats 71 on both sides. The fixed adjustment seats 71 drive the connecting rod 73 to change the angle, thereby completing the height adjustment of the top frame 7. After the adjustment is completed, use bolt 2 72 to fix the position of the fixed adjustment seats 71.

[0060] Step 6: The length of the side beam 8 can also be adjusted according to actual needs to expand the tent structure. Manually loosen bolt 3 82, and then adjust the length of the extension side beam 83 extending beyond the main side beam 81 and the secondary side beam 84. After adjustment, tighten bolt 3 82.

[0061] Step 7: After the tent structure is erected, simply fix the tent fabric 9 to the outside of the tent structure;

[0062] This completes the process of using a scalable tent frame structure and unit tents.
