Description

Technical Field

[0001] The invention relates to the field of trampolines, in particular to an outdoor constant-pressure inflatable trampoline device. Background Art

[0002] Children's amusement facilities are the carriers of children's games. With the development of science, modern games and amusement facilities are becoming more and more diverse. Trampoline amusement facilities have been very popular among children in recent years. They can not only cultivate children's interest in sports, but also exercise their balance and physical strength. The experience gained in the game process helps to improve children's cognitive, emotional, motor and other abilities.

[0003] The existing outdoor constant pressure inflatable trampoline device uses a steel ring to keep it fixed to the ground, but in the process of fixing the steel ring, it is only fixed around and fits the steel ring, so that several connection points between the steel ring and the venue will form a circle. This requires that the circle where the venue and the steel ring fit must be flat and meet the connection requirements of the bolts, which places certain restrictions on the venue, which brings certain restrictions to the preparation work of the entire device.

[0004] Therefore, there is an urgent need for an outdoor constant pressure inflatable trampoline device that can solve the above problems. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an outdoor constant pressure inflatable trampoline device to solve the technical problem.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an outdoor constant pressure inflatable trampoline device, comprising an outer membrane, an inner wall of the outer membrane is provided with an inner liner, a quick fixing device is provided at the bottom of the outer membrane, and an air pressure control device is fixedly connected to the inner wall of the inner liner.

[0007] The outer membrane is a tensioned outer membrane, and the tensioned outer membrane is in a dome state, and the surface of the outer membrane forms a climbing standing surface.

[0008] The present invention is further configured such that the quick fixing device includes an outer steel ring, the outer side of the outer steel ring is evenly spaced with external bolt holes, the inner walls of the external bolt holes are threadedly connected with external connecting columns, the tops of the external connecting columns are evenly spaced with ground connecting bolt holes, the inner wall of the outer steel ring is threadedly connected with internal connecting columns at even intervals, the other end of the internal connecting column is threadedly connected with the inner steel ring, and the ground connecting bolt holes are connected to the ground connecting piece via a bolt connecting piece.

[0009] By adopting the above technical solution, during the fixing process, the device rotates the outer connecting column to rotate out from the inner wall of the outer steel ring, extends the right side of the outer connecting column to the installation horizontal line, and then selects one or more ground connection bolt holes to insert bolts to connect with the ground. By rotating the inner connecting column, the outer steel ring is connected to the inner steel ring, so that the device can limit the inner steel ring while limiting the outer steel ring.

[0010] The outer connection column is fixed to the ground by bolts cooperating with the ground connection bolt holes.

[0011] The present invention is further configured such that the air pressure control device comprises an air inlet pipe and an air outlet pipe, the other end of the air inlet pipe is fixedly connected to an air supply fan, and the other end of the air outlet pipe is fixedly connected to an automatic pressure relief valve.

[0012] By adopting the above technical solution, the air supply fan supplies air to the inner tank through the air inlet pipe. When the air pressure on the inner wall of the inner tank is high, the automatic pressure relief valve senses the gas pressure through the air outlet pipe and discharges the gas on the inner wall of the inner tank through the air outlet pipe.

[0013] The present invention is further configured such that the inner liner is arranged on the inner wall of the outer membrane, and the bottom of the inner liner is fixedly connected to the inner steel ring.

[0014] By adopting the above technical solution, the inner wall of the inner liner expands after being filled with gas, and supports the outer membrane to adopt a separated inflatable gas bag structure. The inner liner and the tensioned outer membrane are separated from each other, which greatly improves the structural strength and service life of the trampoline surface. At the same time, it avoids the need to build a frame and the limitation on the span of the frame in traditional devices, and can be easily and quickly built in various venues.

[0015] The present invention is further configured such that a connecting column nut is fixedly connected to the middle part of the inner connecting column, and both ends of the inner connecting column are respectively provided with an outer connecting column external threaded hole and an inner connecting column threaded hole, the outer connecting column external threaded hole is opened on the inner side of the outer steel ring, and the inner connecting column threaded hole is opened on the outer side of the inner steel ring.

[0016] By adopting the above technical solution, the connecting column nut can drive the inner connecting column to rotate, and can rotate back and forth on the inner walls of the outer threaded hole of the outer connecting column and the threaded hole of the inner connecting column.

[0017] The present invention is further configured such that the outer threaded sleeve of the inner connecting column is provided with a supporting device, the supporting device includes a spring supporting plate, the top of the spring supporting plate is movably connected to a base plate by screws, the bottom of the base plate is threadedly connected to fixing bolts at equal intervals, the other end of the fixing bolts is movably inserted into the fixing bolt holes, the fixing bolt holes are evenly spaced on the inner side of the outer steel ring, and the other end of the base plate is fixedly connected to a soft rubber intercepting rod.

[0018] By adopting the above technical solution, the spring support plate enables the trampoline tensioned outer membrane to bend in accordance with the curved structure when it vibrates and swings, and transmits the tearing tension on the material from the original narrow crease to a wider bending surface, thereby spreading the tension and material fatigue of the tensioned outer membrane and extending the service life of the tensioned outer membrane.

[0019] The soft rubber interception rod is arranged on the outside of the tension outer membrane to block the children from falling from the top of the tension outer membrane to the surrounding areas, thereby ensuring the safety of the children.

[0020] The present invention is further configured such that the number of the external connection posts is several, and one end of the external connection post away from the outer membrane is in contact with the ground.

[0021] By adopting the above technical solution, the number of external connection columns is several, thereby generating several ground connection bolt holes, so that there are multiple position options for the connection points between the external connection columns and the ground.

[0022] The present invention is further configured such that one end of the air inlet pipe and the air outlet pipe penetrates the outer membrane and is fixedly connected to the inner wall of the liner, and a one-way valve is fixedly connected between the air inlet pipe and the air supply fan.

[0023] By adopting the above technical solution, the air inlet pipe and the air outlet pipe are used to inflate and deflate the gas on the inner wall of the liner, and the one-way valve prevents the gas from being discharged from the liner through the air inlet pipe.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. The device as a whole adopts the use of air pressure control device to supply air to the inner liner, so that the inner liner supports the outer membrane, and adopts a separated inflatable air bag structure. The inner liner and the tensioned outer membrane are separated from each other, which greatly improves the structural strength and service life of the trampoline surface. At the same time, it avoids the need to build a frame and the limitation on the span of the frame in traditional devices, and can be easily and quickly built in various venues.

[0026] 2. During the fixing process of the device, there are multiple external connection columns matched with several ground connection bolt holes, so that the connection points between the device and the site can use ground connection bolt holes in different positions according to the different positions of each external connection column, resulting in great rotation of the connection points between the device and the site, which greatly reduces the restrictions on the site.

[0027] 3. By rotating the inner connecting column, the outer steel ring is connected to the inner steel ring, so that the device can limit the inner steel ring while limiting the outer steel ring, reducing the process of limiting the inner steel ring, and further reducing the requirements of the inner steel ring on the site and the time for fixing the inner steel ring.

[0028] 4. The spring support plate enables the trampoline tensioned outer membrane to bend in accordance with the curved structure when it vibrates and swings, and transmits the tearing tension on the material from the original narrow crease to a wider bending surface, spreading the tension and material fatigue of the tensioned outer membrane to extend the service life of the tensioned outer membrane.

[0029] 5. The soft rubber interception rod is set on the outside of the tensioned outer membrane to prevent children from falling from the top of the tensioned outer membrane to the surrounding areas, ensuring the safety of children. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] The following describes an embodiment of the present invention based on its overall structure.

[0039] An outdoor constant pressure inflatable trampoline device, such as Figures 1 to 6 As shown, it includes an outer membrane 1, an inner liner 2 is arranged on the inner wall of the outer membrane 1, a quick fixing device 3 is arranged on the bottom of the outer membrane 1, and an air pressure control device 4 is fixedly connected to the inner wall of the inner liner 2.

[0040] The outer membrane 1 adopts a tensioned outer membrane 11, and the tensioned outer membrane 11 is in a dome state, and the surface of the outer membrane 1 forms a climbing standing surface.

[0041] The quick fixing device 3 includes an outer steel ring 31, the outer side of the outer steel ring 31 is evenly spaced with outer bolt holes 32, the inner wall of the outer bolt hole 32 is threadedly connected with an outer connecting column 33, the top of the outer connecting column 33 is evenly spaced with ground connecting bolt holes 34, the inner wall of the outer steel ring 31 is evenly threadedly connected with inner connecting columns 35, and the other end of the inner connecting column 35 is threadedly connected with an inner steel ring 36.

[0042] During the fixing process, the device rotates the external connecting column 33 so that the external connecting column 33 rotates out from the inner wall of the outer steel ring 31, extends the right side of the external connecting column 33 to the position of the installation horizontal line, and then selects one or more ground connection bolt holes 34 to insert bolts to connect with the ground.

[0043] The outer steel ring 31 is connected to the inner steel ring 36 by rotating the inner connecting column 35 , so that the device can limit the position of the inner steel ring 36 while limiting the position of the outer steel ring 31 .

[0044] The air pressure control device 4 includes an air inlet pipe 41 and an air outlet pipe 42 . The other end of the air inlet pipe 41 is fixedly connected to an air supply fan 43 , and the other end of the air outlet pipe 42 is fixedly connected to an automatic pressure relief valve 44 .

[0045] The air supply fan 43 supplies air to the inner tank 2 through the air inlet pipe 41. When the air pressure on the inner wall of the inner tank 2 is high, the automatic pressure relief valve 44 senses the gas pressure through the air outlet pipe 42 and discharges the gas on the inner wall of the inner tank 2 through the air outlet pipe 42.

[0046] The inner liner 2 is arranged on the inner wall of the outer membrane 1, and the bottom of the inner liner 2 is fixedly connected to the inner steel ring 36. The inner wall of the inner liner 2 is inflated with gas to expand, and the outer membrane 1 is supported to adopt a separated inflatable air bag structure. The inner liner 2 and the tensioned outer membrane 11 are separated from each other, which greatly improves the structural strength and service life of the trampoline surface, and avoids the need to build a frame and the limitation on the span of the frame in the traditional device, and can be easily and quickly built in various venues.

[0047] The ground connection bolt hole 34 is connected to the ground connection piece through a bolt connection piece, and the outer connection column 33 is fixed to the ground through bolts matching the ground connection bolt hole 34 .

[0048] There are several external connection posts 33, one end of which is away from the outer membrane 1 and in contact with the ground. There are several external connection posts 33, thereby generating several ground connection bolt holes 34, so that the connection point between the external connection posts 33 and the ground can be selected in multiple positions.

[0049] One end of the air inlet pipe 41 and the air outlet pipe 42 penetrates the outer membrane 1 and is fixedly connected to the inner wall of the liner 2 . The air inlet pipe 41 and the air outlet pipe 42 are used to inflate and deflate the gas on the inner wall of the liner 2 .

[0050] A one-way valve is fixedly connected between the air inlet pipe 41 and the air supply fan 43 to prevent gas from being discharged from the inner container 2 through the air inlet pipe 41 .

[0051] A connecting column nut 37 is fixedly connected to the middle part of the inner connecting column 35, and the two ends of the inner connecting column 35 are respectively provided with an outer connecting column external threaded hole 38 and an inner connecting column threaded hole 39. The outer connecting column external threaded hole 38 is opened on the inner side of the outer steel ring 31, and the inner connecting column threaded hole 39 is opened on the outer side of the inner steel ring 36, so that the connecting column nut 37 can drive the inner connecting column 35 to rotate, and can rotate back and forth on the inner walls of the outer connecting column external threaded hole 38 and the inner connecting column threaded hole 39.

[0052] The outer thread sleeve of the inner connecting column 35 is provided with a supporting device 5, and the supporting device 5 includes a spring supporting plate 51, the bottom thread sleeve of the spring supporting plate 51 is arranged on the outer side of the inner connecting column 35, the top of the spring supporting plate 51 is movably connected with a bottom plate 52 by screws, and the bottom of the bottom plate 52 is threadedly connected with fixing bolts 53 at equal intervals, and the other end of the fixing bolt 53 is movably inserted into the fixing bolt hole 54, and the fixing bolt holes 54 are arranged at equal intervals on the inner side of the outer steel ring 31, and the other end of the bottom plate 52 is fixedly connected with a soft rubber intercepting rod 55. The spring supporting plate 51 enables the trampoline tensioning outer membrane 11 to bend in accordance with the curved surface structure when it vibrates and swings, and transmits the tearing tension exerted on the material from the original narrow line crease to a wider bending surface, thereby spreading the tension and material fatigue of the tensioning outer membrane 11 and extending the service life of the tensioning outer membrane 11.

[0053] The soft rubber interception rod 55 is arranged on the outside of the tension outer membrane 11 to prevent children from falling from the top of the tension outer membrane 11 to the surrounding areas, thereby ensuring the safety of the children.

[0054] During use of the present invention, since the device as a whole adopts an air pressure control device 4 to supply air to the inner liner 2, the inner liner 2 supports the outer membrane 1, and adopts a separated inflatable air bag structure. The inner liner 2 and the tensioned outer membrane 11 are separated from each other, which greatly improves the structural strength and service life of the trampoline surface. At the same time, it avoids the need to build a frame and the limitation on the span of the frame construction in traditional devices, and can be easily and quickly built in various venues.

[0055] During the fixing process of the device, the external connecting column 33 is rotated so that the external connecting column 33 is rotated out from the inner wall of the outer steel ring 31, and the right side of the external connecting column 33 is extended to the position of the installation horizontal line, and then one or more ground connecting bolt holes 34 are selected to insert the bolts to connect with the ground. Since there are multiple external connecting columns 33 and multiple ground connecting bolt holes 34, the connection point between the device and the site can use ground connecting bolt holes 34 in different positions according to the different positions of the connecting columns 33, so that the connection point between the device and the site has great rotatability, which greatly reduces the restrictions on the site.

[0056] By rotating the inner connecting column 35, the outer steel ring 31 is connected to the inner steel ring 36, so that the device can limit the inner steel ring 36 while limiting the outer steel ring 31, thereby reducing the process of limiting the inner steel ring 36 and further reducing the site requirements of the inner steel ring 36 and the time it takes to fix the inner steel ring 36.

[0057] When the device is in use, the air supply fan 43 supplies air to the inner tank 2 through the air inlet pipe 41. When the air pressure on the inner wall of the inner tank 2 is high, the automatic pressure relief valve 44 senses the gas pressure through the air outlet pipe 42 and discharges the gas on the inner wall of the inner tank 2 through the air outlet pipe 42.

[0058] The spring support plate 51 enables the trampoline tensioned outer membrane 11 to bend in accordance with the curved structure when it vibrates and swings, and transmits the tearing tension on the material from the original narrow crease to a wider bending surface, thereby spreading the tension and material fatigue of the tensioned outer membrane 11 and extending the service life of the tensioned outer membrane 11.

[0059] The soft rubber interception rod 55 is arranged on the outside of the tension outer membrane 11 to prevent children from falling from the top of the tension outer membrane 11 to the surrounding areas, thereby ensuring the safety of the children.
