[0002] In home fitness trampolines, to ensure safety, especially for children, some trampolines are equipped with handrails. Currently, among trampolines with handrails on the market, one type has its legs connected to the trampoline frame via threaded plugs, resulting in an unstable leg installation angle. When installing the handrails, they are typically connected to the legs via an outer sleeve, with one or two nuts welded to the sleeve, and then secured with bushings and injection-molded locking screws, as shown in patent CN201006221Y for a small trampoline with handrails. However, this method of securing the handrails is prone to loosening, requires numerous parts, has a complex structure, and is inconvenient to install. Therefore, for trampolines with unstable leg installation angles, improving the connection strength between the handrails and the trampoline and simplifying the handrail installation is a pressing technical problem that needs to be solved. Utility Model Content

[0004] This utility model provides a trampoline with handrails, including a bed frame and handrails. The bed frame includes a trampoline frame and legs threadedly connected to the trampoline frame. Multiple threaded holes are formed circumferentially on the outer wall of the legs. The handrails are connected to the legs via handrail connecting assemblies. The handrail connecting assemblies include: The outer sleeve is fixedly connected to the lower part of the handrail and fitted over the support leg. The outer sleeve has a through groove extending in the circumferential direction. When the handrail is at its preset installation height, the vertical position of the through groove corresponds to the vertical position of the threaded hole on the support leg. When the outer sleeve and the support leg are assembled at any angle, at least one threaded hole is connected to the through groove. The first fastener includes a screw portion and an abutment portion connected to one axial end of the screw portion. The screw portion passes through a through groove and is threadedly connected to a threaded hole communicating with the through groove. The abutment portion cannot pass through the through groove. When the screw portion is tightened with the threaded hole, the abutment portion abuts against the outer wall of the outer sleeve to press the outer sleeve against the support leg.

[0005] In some embodiments, the legs are cylindrical or tubular, and multiple threaded holes are arranged in a ring array on the outer periphery of the legs; the outer sleeve is tubular, and the central angle corresponding to the arc of the through groove is greater than the interval angle between two adjacent threaded holes, so that when the outer sleeve and the legs are assembled at any angle, at least one threaded hole is connected to the through groove.

[0006] In some embodiments, the number of threaded holes on the same leg is 3 to 8.

[0007] In some embodiments, the central angle corresponding to the arc where the through slot is located is 90°~180°.

[0008] In some embodiments, four threaded holes are opened on the same leg, the interval angle between two adjacent threaded holes is 90°, and the central angle corresponding to the arc where the through groove is located is 120°.

[0009] In some embodiments, the through groove is located on the outer wall of the outer sleeve on the side opposite to the handrail.

[0010] In some embodiments, the handrail includes two vertically arranged risers and a handrail tube detachably connected between the tops of the two risers. The lower part of each riser is connected to a support leg with a threaded hole through an outer sleeve, and the top of the riser extends above the trampoline frame.

[0011] In some embodiments, the armrest connection assembly further includes: The buffer block is fixedly connected to the edge of the trampoline frame and fills the gap between the riser and the trampoline frame; The second fastener passes through the riser and is threaded to the buffer block to securely connect the riser and the buffer block.

[0012] In some embodiments, the side of the buffer block facing away from the trampoline frame has a groove, and the side of the riser facing the trampoline frame is accommodated in the groove.

[0013] In some embodiments, the buffer block has a buffer cavity to allow the buffer block to deform as the handrail swings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] As attached Figures 1-8As shown in an illustrative embodiment of the trampoline with armrests of this utility model, the trampoline with armrests includes a bed frame 1 and armrests 2. The bed frame 1 includes a trampoline frame 11 and support legs 12 threadedly connected to the trampoline frame 11. The outer wall of the support legs 12 has a plurality of threaded holes 121 circumferentially formed. The armrests 2 are connected to the support legs 12 through armrest connecting components 3. The armrest connecting components 3 include an outer sleeve 31 and a first fastener 32. The outer sleeve 31 is fixedly connected to the lower part of the armrests 2 and sleeved on the outside of the support legs 12. The outer sleeve 31 has a through groove 311 extending circumferentially. When the armrests 2 are at their preset installation height, the vertical direction of the through groove is... The position corresponds to the vertical position of the threaded hole 121 on the support leg 12, and at least one threaded hole 121 is connected to the through groove 311 when the outer sleeve 31 and the support leg 12 are assembled at any angle; the first fastener 32 includes a screw part 321 and an abutment part 322 connected to one axial end of the screw part 321. The screw part 321 passes through the through groove 311 and is threadedly connected to the threaded hole 121 that communicates with the through groove 311. The abutment part 322 cannot pass through the through groove 311. When the screw part 321 is tightened to the threaded hole 121, the abutment part 322 abuts against the outer wall of the outer sleeve 31 to press the outer sleeve 31 against the support leg 12.

[0022] In the aforementioned trampoline with handrails, the installation process of the handrails 2 is as follows: After assembling the trampoline frame 11 and the support legs 12 into the bed body 1 via a threaded connection, the outer sleeve 31 connected to the lower part of the handrail 2 is fitted over the support legs 12 from bottom to top, and the handrail 2 is adjusted to the preset installation height. Since the through groove 311 of the outer sleeve 31 extends circumferentially along the outer sleeve 31, the through groove 311 has a certain length, and the outer wall of the support legs 12 is pre-drilled with multiple threaded holes 121 along the circumferential direction, allowing at least one threaded hole to be inserted. The threaded hole 121 is connected to the through groove 311. The screw part 321 of the first fastener 32 is passed through the through groove 311 and screwed into the threaded hole 121 connected in the through groove 311. The first fastener 32 is rotated until the abutting part 322 of the first fastener 32 abuts against the outer wall of the outer sleeve 31. The first fastener 32 is tightened so that the abutting part 322 applies radial pressure to the outer sleeve 31, thereby pressing and fixing the outer sleeve 31 to the outer wall of the support leg 12, thus completing the connection between the armrest 2 and the trampoline frame 11.

[0023] The aforementioned trampoline with armrests features multiple threaded holes 121 circumferentially formed on the outer wall of the support leg 12 and a circumferentially extending through groove 311 formed on the outer sleeve 31 of the armrest 2. This ensures that after the support leg 12 is installed on the trampoline frame 11 via a threaded connection, when the outer sleeve 31 is fitted over the support leg 12, regardless of the assembly angle of the outer sleeve 31 relative to the support leg 12, at least one threaded hole 121 on the outer wall of the support leg 12 can communicate with the through groove 311 of the outer sleeve 31. This allows the screw portion 321 of the first fastener 32 to be inserted into the aligned threaded hole 121 after passing through the through groove 311. By tightening the first fastener 32, the outer sleeve 31 and the support leg 12 can be securely connected, thus completing the connection between the armrest 2 and the trampoline frame 11. The installation of the armrest 2 is simple and significantly improves assembly efficiency. Meanwhile, after the outer sleeve 31 of the armrest 2 is connected to the trampoline support leg 12 by tightening the first fastener 32, radial pressure can be applied to the outer sleeve 31 through the abutment part 322 of the first fastener 32, ensuring the connection is firm and not easy to loosen. In addition, the armrest connection assembly 3 of the above-mentioned trampoline with armrests has a simple structure and requires fewer parts, which greatly reduces the production cost.

[0024] In the trampoline with handrails described above, it should be noted that the support leg 12 is cylindrical or tubular, and the outer sleeve 31 is tubular to fit over the support leg 12. It should also be noted that in this embodiment, the first fastener 32 is specifically a screw; however, those skilled in the art may use other fasteners with a threaded portion and an abutment portion as the first fastener.

[0025] To ensure that at least one threaded hole 121 can communicate with the through slot 311 when the outer sleeve 31 and the support leg 12 are assembled at any angle, in some embodiments, such as Figure 4 and Figure 6 As shown, multiple threaded holes 121 are arranged in a ring array on the outer periphery of the support leg 12. The central angle β corresponding to the arc where the through groove is located is greater than the interval angle α between two adjacent threaded holes 121, so that when the outer sleeve 31 and the support leg 12 are assembled at any angle, at least one threaded hole 121 is connected to the through groove 311.

[0026] Preferably, the number of threaded holes 121 on the same support leg 12 is 3 to 8. If the number of threaded holes 121 on the support leg 12 is too small, a longer through groove 311 needs to be made, which will affect the structural strength of the outer sleeve 31 and thus affect the firmness of the handrail 2 connection; if the number of threaded holes 121 on the support leg 12 is too large, it will affect the structural strength of the support leg 12 and increase the amount of processing.

[0027] Preferably, the central angle β corresponding to the arc of the through groove is 90°~180°. The size of the central angle β corresponding to the arc of the through groove determines the length of the through groove 311. If the length of the through groove 311 is too short, more threaded holes 121 need to be machined on the support leg 12 to ensure that at least one threaded hole 121 can be connected to the through groove 311 when the outer sleeve 31 and the support leg 12 are assembled at any angle. However, too many threaded holes 121 will affect the structural strength of the support leg 12 and increase the amount of machining. If the length of the through groove 311 is too long, the structural strength of the outer sleeve 31 will be affected, which in turn will affect the firmness of the connection of the handrail 2.

[0028] Optimal, there are 4 threaded holes 121 on the same support leg 12, the interval angle α between two adjacent threaded holes 121 is 90°, and the central angle β corresponding to the arc where the through groove is located is 120°.

[0029] In some embodiments, such as Figure 2 As shown, the through groove 311 is located on the outer wall of the outer sleeve 31 on the side away from the handrail 2. By opening the through groove 311 on the side of the outer sleeve 31 away from the handrail 2, the through groove 311 can be moved away from the handrail 2, reducing the deformation of the outer sleeve 31 at the through groove 311 caused by the swinging of the handrail 2 during trampoline use.

[0030] In some embodiments, such as Figure 1 As shown, the handrail 2 includes two vertically arranged uprights 21 and a handrail tube 22 detachably connected between the tops of the two uprights 21. The lower part of each upright 21 is connected to a support leg 12 with a threaded hole 121 via an outer sleeve 31. The top of the upright 21 extends above the trampoline frame 11. The handrail 2 structure, with two uprights 21 and handrail tube 22, facilitates the installation of the handrail 2. During installation, the two uprights 21 are first installed onto the support leg 12 via the outer sleeve 31 and the first fastener 32, and then the two ends of the handrail tube 22 are connected to the two uprights 21 respectively, thus completing the installation of the handrail 2. It should be noted that in this embodiment, the handrail tube 22 and the uprights 21 are connected by a plug-in connection. It is understood that those skilled in the art can also use other detachable connection methods to connect the handrail tube 22 and the uprights 21, such as snap-fit ​​or fittings.

[0031] To improve the stability of the connection between the armrest 2 and the bed frame 1, and to prevent collisions between the riser 21 and the trampoline frame 11 caused by the swinging of the armrest 2 during trampoline use, in some embodiments, such as Figure 9As shown, the handrail connecting assembly 3 also includes a buffer block 33 and a second fastener 34. The buffer block 33 is fixedly connected to the edge of the trampoline frame 11 and fills the gap between the riser 21 and the trampoline frame 11. The second fastener 34 passes through the riser 21 and is threadedly connected to the buffer block 33, so that the riser 21 and the buffer block 33 are securely connected. The buffer block 33 acts as a buffer between the riser 21 and the trampoline frame 11, which can prevent the riser 21 from colliding with the trampoline frame 11 due to the swinging of the handrail 2 during trampoline use. At the same time, by connecting the riser 21 to the buffer block 33 through the second fastener 34, the firmness of the connection between the handrail 2 and the bed 1 can be further improved. It should be noted that the second fastener 34 is specifically a screw, but those skilled in the art can also use other fasteners as the second fastener.

[0032] In some embodiments, such as Figure 9 As shown, the buffer block 33 has a groove 331 on the side facing away from the trampoline frame 11, and the side of the upright tube 21 facing the trampoline frame 11 is accommodated in the groove 331. The buffer block 33 contacts the upright tube 21 through the groove 331, which can improve the fit between the buffer block 33 and the outer wall of the upright tube 21.

[0033] In some embodiments, such as Figure 9 As shown, the buffer block 33 has a buffer cavity 332, which allows the buffer block 33 to deform as the armrest 2 swings. The buffer block 33 deforms through the buffer cavity 332, which can better buffer the force of the armrest 2 swinging during trampoline use.

[0034] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
