Description

Technical Field

[0001] This utility model relates to the field of tents, and in particular to a tensioning structure for tent fabric. Background Technology

[0002] Tents, as a type of temporary structure, are widely used in many occasions due to their flexibility, convenience, and ability to be quickly erected and dismantled. Whether it's outdoor events, exhibition venues, temporary storage, or construction sites, tents are a common sight. The tent roof typically consists of a main supporting beam, side supporting beams, and the tent fabric. The main and side supporting beams jointly bear the weight of the tent fabric and withstand the pressure from external factors such as wind and rain.

[0003] However, due to the weight of the main support beam and the side support beam, it is difficult to move them. This makes it difficult to adjust the tension of the tarpaulin fixed to the main support beam and the side support beam. If the tarpaulin is too loose, the top structure of the tent will be unstable when encountering strong winds or other severe weather, and may even collapse. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tensioning structure for tent fabric. The purpose is to solve the technical problem that, due to the weight of the main supporting beam and the side supporting beam, it is difficult to move the main supporting beam or the side supporting beam, which makes it difficult to adjust the tension of the tent fabric fixed to the main supporting beam and the side supporting beam. If the tent fabric is too loose, the top structure of the tent will be unstable when encountering strong winds or other severe weather, and may even collapse.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A tensioning structure for a tent tarpaulin includes a main supporting beam with multiple connecting beams on both sides. One end of each connecting beam has a supporting side beam. A tent tarpaulin is connected between the main supporting beam and the supporting side beam. One end of each connecting beam has a first adjusting groove. One side of each supporting side beam has a first adjusting strip that slides into an adjacent first adjusting groove. One side of each first adjusting strip has multiple first adjusting holes. One side of each connecting beam has a first fixing hole communicating with the first adjusting groove, corresponding to any one of the first adjusting holes. A tensioning cylinder is located on one side of each connecting beam, close to an adjacent supporting side beam. One end of the tensioning cylinder has a tensioning head that abuts against an adjacent supporting side beam.

[0007] In the initial stage of tent setup, the tent fabric is in a loose state. At this time, the first adjusting strip is inserted into the first adjusting groove of the adjacent connecting beam to achieve initial connection between the connecting beam and the supporting side beam. First, the supporting main beam is fixed on the ground, and the tensioning cylinder is activated. The piston rod of the tensioning cylinder pushes the tensioning head towards the supporting side beam. After the tensioning head contacts the supporting side beam, it continues to push the supporting side beam, causing it to move outward and increasing the distance between the supporting main beam and the supporting side beam. Since the tent fabric is placed between the supporting main beam and the supporting side beam, it gradually tightens under the pull of the supporting side beam. When the tent fabric reaches the appropriate tension, the extension and retraction of the tensioning cylinder is stopped. At this time, the first fixing hole corresponds to any of the first adjusting holes. By screwing the screw into the first fixing hole and the corresponding first adjusting hole, the position of the supporting side beam after movement is fixed, ensuring that the tent fabric will not change due to external forces in the tensioned state. This facilitates the adjustment of the tent fabric tension, and the push of the tensioning cylinder ensures precise control of the tent fabric tension.

[0008] Furthermore, in this application, a tensioning frame is provided on one side of the tensioning cylinder, and a first mounting cavity is provided at one end of the tensioning frame. The first mounting cavity matches the shape of the connecting beam, and the first mounting cavity is detachably connected to the connecting beam.

[0009] The tensioning frame is detachably connected to the connecting beam through the first mounting cavity. The structural design of the first mounting cavity allows the tensioning frame to be installed on any connecting beam. This allows the tensioning cylinder to apply tension to different positions of the supporting side beam through the flexible position adjustment of the tensioning frame, so as to adapt to the diversity of tarpaulin tensioning requirements.

[0010] Furthermore, in this application, the connecting beam has a fixed cavity inside, and the connecting beam has first through holes on both sides that communicate with the fixed cavity. The tensioning frame has second through holes on both sides that communicate with the first mounting cavity. The fixed cavity has a fixed spring inside, and the fixed spring has movable seats at both ends. One end of the movable seat has a fixed pin, and the fixed pin passes through the adjacent first through hole so that one end of the fixed pin engages with the adjacent second through hole.

[0011] When the tensioning frame is installed on the corresponding connecting beam, the fixing pin of the fixing cavity passes through the adjacent first through hole, so that the fixing pin engages with the adjacent second through hole. The fixing pin fixes the position of the tensioning frame under the elastic action of the fixing spring. When disassembly is required, press the fixing pin, and the fixing pin drives the fixing spring to retract, so that the fixing pin disengages from the second through hole, thereby facilitating the disassembly of the tensioning frame. The spring structure realizes the quick installation and disassembly of the tensioning frame, simplifying the installation process of the tensioning frame.

[0012] Furthermore, in this application, the other end of any of the movable seats is provided with a guide post, which slides in conjunction with the interior of the adjacent fixed spring.

[0013] Furthermore, in this application, the other end of the tensioning frame is provided with a mounting bracket, the mounting bracket has a second mounting cavity inside, the tensioning cylinder passes through the interior of the second mounting cavity, and a second fixing hole communicating with the second mounting cavity is provided on one side of the mounting bracket, the second fixing hole facing the tensioning cylinder.

[0014] Furthermore, in this application, a second adjustment groove is provided at the other end of the connecting beam, and second adjustment strips are provided on both sides of the supporting main beam. The second adjustment strips are slidably engaged with the adjacent second adjustment grooves. A plurality of second adjustment holes are provided on one side of the second adjustment strips, and a third fixing hole is provided on one side of the connecting beam. The third fixing hole corresponds to any of the second adjustment holes.

[0015] Furthermore, in this application, a mounting cylinder is provided on one side of the tensioning head, the mounting cylinder is inserted into the piston rod of the tensioning cylinder, a fourth fixing hole communicating with the interior of the mounting cylinder is provided on one side of the mounting cylinder, and a fifth fixing hole is provided on one side of the piston rod of the tensioning cylinder, the fourth fixing hole and the fifth fixing hole correspond to each other.

[0016] Furthermore, in this application, the supporting main beam and the supporting side beam are connected by a plurality of first connecting steel cables and a plurality of second connecting steel cables.

[0017] Furthermore, in this application, the first connecting steel cable is staggered with the adjacent second connecting steel cable, the first connecting steel cable, the adjacent second connecting steel cable and the adjacent supporting side beam form a triangular shape, the first connecting steel cable, the adjacent second connecting steel cable and the adjacent connecting beam form a triangular shape, and the first connecting steel cable, the adjacent second connecting steel cable and the adjacent supporting main beam form a triangular shape.

[0018] Furthermore, in this application, the bottom of the supporting side beam is provided with multiple supporting columns.

[0019] This utility model has the following beneficial effects:

[0020] In the initial stage of tent setup, the tent fabric is in a loose state. At this time, the first adjusting strip is inserted into the first adjusting groove of the adjacent connecting beam to achieve initial connection between the connecting beam and the supporting side beam. First, the supporting main beam is fixed on the ground, and the tensioning cylinder is activated. The piston rod of the tensioning cylinder pushes the tensioning head towards the supporting side beam. After the tensioning head contacts the supporting side beam, it continues to push the supporting side beam, causing it to move outward and increasing the distance between the supporting main beam and the supporting side beam. Since the tent fabric is placed between the supporting main beam and the supporting side beam, it gradually tightens under the pull of the supporting side beam. When the tent fabric reaches the appropriate tension, the extension and retraction of the tensioning cylinder is stopped. At this time, the first fixing hole corresponds to any of the first adjusting holes. By screwing the screw into the first fixing hole and the corresponding first adjusting hole, the position of the supporting side beam after movement is fixed, ensuring that the tent fabric will not change due to external forces in the tensioned state. This facilitates the adjustment of the tent fabric tension, and the push of the tensioning cylinder ensures precise control of the tent fabric tension. Attached Figure Description

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Reference Figures 1-4 In some specific embodiments, a tensioning structure for a tent tarpaulin includes a supporting main beam 2, multiple connecting beams 4 on both sides of the supporting main beam 2, a supporting side beam 3 at one end of the connecting beam 4, a tarpaulin 1 connected between the supporting main beam 2 and the supporting side beam 3, a first adjusting groove 6 at one end of the connecting beam 4, a first adjusting insert 7 on one side of the supporting side beam 3, the first adjusting insert 7 slidingly engaging with the adjacent first adjusting groove 6, multiple first adjusting holes 10 on one side of the first adjusting insert 7, a first fixing hole 11 communicating with the first adjusting groove on one side of the connecting beam 4, the first fixing hole 11 corresponding to any one of the first adjusting holes 10, a tensioning cylinder 24 on one side of the connecting beam 4, the tensioning cylinder 24 being close to the adjacent supporting side beam 3, a tensioning head 27 at one end of the tensioning cylinder 24, and the tensioning head 27 abutting against the adjacent supporting side beam 3.

[0033] Through the above technical solution, in the initial stage of tent construction, the tent fabric 1 is in a loose state. At this time, the first adjusting strip 7 is inserted into the first adjusting groove 6 of the adjacent connecting beam 4 to achieve the initial connection between the connecting beam 4 and the supporting side beam 3. At this time, the supporting main beam 2 is first fixed on the ground, and the tensioning cylinder 24 is activated, causing the piston rod of the tensioning cylinder 24 to push the tensioning head 27 towards the supporting side beam 3. After the tensioning head 27 contacts the supporting side beam 3, it continues to push the supporting side beam 3, causing the supporting side beam 3 to move outward, thus increasing the distance between the supporting main beam 2 and the supporting side beam 3. Since the tent fabric 1 is set on the support... Between the main support beam 2 and the supporting side beam 3, the tarpaulin 1 is gradually tensioned under the pull of the supporting side beam 3. When the tarpaulin 1 reaches the appropriate tension, the extension and retraction of the tensioning cylinder 24 is stopped. At this time, the first fixing hole 11 corresponds to any of the first adjusting holes 10. By screwing the screw into the first fixing hole 11 and the corresponding first adjusting hole 10, the position of the supporting side beam 3 after movement is fixed, so as to ensure that the tarpaulin 1 will not change due to external force in the tensioned state, thereby facilitating the adjustment of the tension of the tarpaulin 1. And by pushing the tensioning cylinder 24, the precise control of the tension of the tarpaulin 1 is ensured.

[0034] In addition, if the tarpaulin 1 becomes loose or the tent structure needs to be adjusted during use, the screws can be unscrewed and the tension cylinder 24 can be reactivated to readjust the tension of the tarpaulin 1; the connection between the first fixing hole 11 and the first adjusting hole 10 can be replaced with a quick-connect buckle to improve assembly efficiency.

[0035] It should be noted that the tensioning cylinder 24 can be connected to an external circuit for power supply or a mobile power supply can be installed on one side of the tensioning cylinder 24; and since there are multiple connecting beams 4, in order to make the supporting side beam 3 move evenly on one side, it is necessary to ensure that the tensioning head 27 of the tensioning cylinder 24 of each adjacent connecting beam 4 is in contact with the supporting side beam 3, so that when multiple tensioning cylinders 24 are activated, the supporting side beam 3 can be moved synchronously.

[0036] Reference Figures 3-4 In some specific embodiments, a tensioning frame 18 is provided on one side of the tensioning cylinder 24, and a first mounting cavity 19 is provided at one end of the tensioning frame 18. The first mounting cavity 19 matches the shape of the connecting beam 4, and the first mounting cavity 19 is detachably connected to the connecting beam 4.

[0037] Through the above technical solution, the tensioning frame 18 is detachably connected to the connecting beam 4 through the first mounting cavity 19. The structural design of the first mounting cavity 19 allows the tensioning frame 18 to be installed on any connecting beam 4, which enables the tensioning cylinder 24 to be flexibly adjusted in position and can apply tension to different positions of the supporting side beam 3 to adapt to the diversity of the tarpaulin 1 tensioning requirements.

[0038] In addition, the connection between the first mounting cavity 19 and the connecting beam 4 can be replaced by a slide rail type buckle, so that the tensioning frame 18 can select any position of the connecting beam 4 to change its fixed position.

[0039] Reference Figure 4 In some specific embodiments, a fixed cavity 12 is provided inside the connecting beam 4, and first through holes 13 communicating with the fixed cavity 12 are provided on both sides of the connecting beam 4. Second through holes 20 communicating with the first mounting cavity 19 are provided on both sides of the tensioning frame 18. A fixed spring 14 is provided inside the fixed cavity 12. Movable seats 15 are provided at both ends of the fixed spring 14. A fixed pin 16 is provided at one end of the movable seat 15. The fixed pin 16 passes through the adjacent first through hole 13, so that one end of the fixed pin 16 is engaged with the adjacent second through hole 20.

[0040] With the above technical solution, when the tensioning frame 18 is installed on the corresponding connecting beam 4, the fixing pin 16 of the fixing cavity 12 passes through the adjacent first through hole 13, so that the fixing pin 16 is engaged with the adjacent second through hole 20. The fixing pin 16 fixes the position of the tensioning frame 18 under the elastic action of the fixing spring 14. When disassembly is required, the fixing pin 16 is pressed, and the fixing pin 16 drives the fixing spring 14 to retract, so that the fixing pin 16 disengages from the second through hole 20, thereby facilitating the disassembly of the tensioning frame 18. The spring structure realizes the quick installation and disassembly of the tensioning frame 18, simplifying the installation process of the tensioning frame 18.

[0041] Reference Figure 4 In some specific embodiments, the other end of any movable seat 15 is provided with a guide post 17, which slides in conjunction with the interior of the adjacent fixed spring 14.

[0042] With the above technical solution, the guide post 17 is set at the other end of any movable seat 15 and slides in cooperation with the inside of the fixed spring 14, so that the fixed spring 14 provides a stable guiding effect when compressed or extended, ensuring that the fixed pin 16 moves smoothly along the spring axis and avoiding lateral displacement from affecting the structural strength or connection stability.

[0043] Reference Figures 5-6 In some specific embodiments, the other end of the tensioning frame 18 is provided with a mounting frame 21, and a second mounting cavity 22 is provided inside the mounting frame 21. The tensioning cylinder 24 passes through the second mounting cavity 22. A second fixing hole 23 communicating with the second mounting cavity 22 is provided on one side of the mounting frame 21, and the second fixing hole 23 faces the tensioning cylinder 24.

[0044] Through the above technical solution, the mounting bracket 21 accommodates the tension cylinder 24 through the second mounting cavity 22, and the second fixing hole 23 can be screwed through to abut against the tension cylinder 24, ensuring the stable installation of the tension cylinder 24. Moreover, when the tension cylinder 24 is damaged, it can be quickly disassembled by loosening the screw of the second fixing hole 23 without complicated operations on other structures, and it is also particularly convenient for quick replacement of the cylinder.

[0045] Reference Figures 5-6 In some specific embodiments, a second adjustment groove 30 is provided at the other end of the connecting beam 4, and a second adjustment strip 29 is provided on both sides of the supporting main beam 2. The second adjustment strip 29 slides with the adjacent second adjustment groove 30. A plurality of second adjustment holes 31 are provided on one side of the second adjustment strip 29, and a third fixing hole 32 is provided on one side of the connecting beam 4. The third fixing hole 32 corresponds to any of the second adjustment holes 31.

[0046] With the above technical solution, before the tarpaulin 1 is tensioned, the main support beam 2 can move toward the two support side beams 3, so that the second adjustment insert 29 of the main support beam 2 slides along the second adjustment groove 30, and the third fixing hole 32 corresponds to any of the second adjustment holes 31, so that the screw can be threaded through the third fixing hole 32 and the corresponding second adjustment hole 31, thereby facilitating the pre-position adjustment before the main support beam 2 is installed.

[0047] Reference Figure 4 In some specific embodiments, a mounting cylinder 26 is provided on one side of the tensioning head 27. The mounting cylinder 26 is inserted into the piston rod of the tensioning cylinder 24. A fourth fixing hole 28 communicating with the interior of the mounting cylinder 26 is provided on one side of the mounting cylinder 26. A fifth fixing hole 25 is provided on one side of the piston rod of the tensioning cylinder 24. The fourth fixing hole 28 and the fifth fixing hole 25 correspond to each other.

[0048] Through the above technical solution, a mounting cylinder 26 is designed on one side of the tensioning head 27 to realize the plug-in connection between the piston rod of the tensioning cylinder 24 and the tensioning head 27. The fourth fixing hole 28 inside the mounting cylinder 26 corresponds to the fifth fixing hole 25 on the piston rod. The two can be fixed together by screws to ensure that the tensioning head 27 is subjected to uniform force during the tensioning process, and it is also convenient to quickly disassemble and replace the tensioning head 27 when needed, thereby improving the maintenance efficiency of the entire system.

[0049] Reference Figures 1-2 In some specific embodiments, a plurality of first connecting steel cables 5 and a plurality of second connecting steel cables 9 are connected between the main supporting beam 2 and the supporting side beam 3.

[0050] Through the above technical solution, by setting the first connecting steel cable 5 and the second connecting steel cable 9 between the supporting main beam 2 and the supporting side beam 3, an auxiliary tension support system is formed, which effectively disperses the structural stress of the tent under wind load or other external forces, and reduces the risk of damage to the supporting main beam 2 and the supporting side beam 3.

[0051] Reference Figures 1-2 In some specific embodiments, the first connecting steel cable 5 is staggered with the adjacent second connecting steel cable 9, the first connecting steel cable 5, the adjacent second connecting steel cable 9 and the adjacent supporting side beam 3 are arranged in a triangular shape, the first connecting steel cable 5, the adjacent second connecting steel cable 9 and the adjacent connecting beam 4 are arranged in a triangular shape, and the first connecting steel cable 5, the adjacent second connecting steel cable 9 and the adjacent supporting main beam 2 are arranged in a triangular shape.

[0052] Through the above technical solution, since the triangular structure has high geometric stability, the combination of triangular units in multiple locations can effectively disperse the wind load or other external forces on the tent, thereby enhancing the tent's resistance to deformation under various environmental conditions.

[0053] Reference Figures 1-2 In some specific embodiments, the bottom of the supporting side beam 3 is provided with multiple supporting columns 33.

[0054] Through the above technical solution, multiple support columns 33 are set at the bottom of the support side beam 3, forming a stable ground support system that can distribute the weight and tension of the tent, provide reliable load-bearing capacity, and prevent the tent from tilting or sliding due to uneven ground.
