Description

Technical Field

[0001] The present invention relates to the technical field of trampolines, in particular to a trampoline and processing equipment thereof. Background Art

[0002] In the modern leisure and sports sector, trampolines, as a device that combines both fun and fitness, are widely used in home entertainment, sports training, children's playgrounds, and other settings. Their core structure, as described in patent number CN219375978U, consists of an elastic bed, several springs, and a support frame. The springs are the key components connecting the bed and the support frame, and their stress state directly affects the performance and safety of the trampoline. Currently, trampoline support frames are often constructed from welded metal pipes, with multiple support frame units connected by welding to form a stable overall structure capable of withstanding the impact of user movement. However, during the actual manufacturing process, the multi-section curved pipes themselves exhibit deformation errors, which are further compounded by welding. This deformation is not evenly distributed, and can cause slight spatial offsets between the connection points of the support frame, disrupting the originally designed symmetrical structure. When the springs are installed between the deformed support frame and the bed surface, the initial stretched lengths of the springs will vary due to the deviations in the connection points, resulting in uneven initial spring tension. This initial tension difference is further amplified when the user exercises on the trampoline: springs subjected to greater forces will deform more under the same external force, while springs subjected to less force will deform less, resulting in uneven spring deformation. Summary of the Invention

[0003] The present invention addresses the deficiencies in the prior art and provides a trampoline and a processing device thereof. The spring is tightened by a quick-install device, and then the spring deformation length is uniformed by the movement of a sliding seat.

[0024] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1:

[0025] See also Figures 1-8 A trampoline and its processing equipment include a support frame 1, an elastic bed surface 2, a spring 3 and an adjusting device 4. A plurality of adjusting devices 4 are evenly arranged on the support frame 1. The adjusting device 4 includes a fixed seat 41, a sliding seat 42, a calibration device 43 and a quick-install device 44 fixed to the sliding seat 42 by bolts. One end of the spring 3 is arranged on the quick-install device 44, and the other end is arranged on the tensioning steel ring of the elastic bed surface 2. The quick-install device 44 is used to quickly lengthen the spring 3.

[0026] The quick-loading device 44 includes a base 441 and a rotating base 442, and the base 441 is fixed to the sliding base 42 by bolts, wherein one end of the rotating base 442 is rotatably arranged on the front end of the base 441, and the other end is provided with a rotating shaft, and one end of the rotating shaft is sleeved on the spring 3, and the other end of the spring 3 is used to hook on the tensioning steel ring of the elastic bed surface 2. A locking tongue 443 is also elastically guided and slidably arranged on the base 441, and the upper end of the locking tongue 443 is provided with an arc surface. When the rotating base 442 is flipped downward, the edge presses on the arc surface of the locking tongue 443, thereby causing the locking tongue 443 to elastically retract and leave the rotating range of the rotating base 442. After the rotating base 442 passes, the locking tongue 443 extends forward again under the action of the elastic member, thereby limiting the rotating base 442 and preventing it from rotating.

[0027] When assembling the trampoline, one end of the spring 3 is first placed on the rotating shaft of the rotating seat 442, and the other end is hooked on the tensioning steel ring of the elastic bed surface 2. After all the springs 3 are hooked, the rotating seat 442 is flipped one by one. The flipping of the rotating seat 442 puts the spring 3 in an elongated state. After the rotating seat 442 is rotated into place, the locking tongue 443 automatically locks the rotating seat 442.

[0028] At the same time, an inclined resistance surface is provided on the base 441, and the rotating seat 442 is flipped into place, that is, pressed on the inclined resistance surface. At this time, the angle between the rotating seat 442 and the spring 3 is less than 180 degrees. Therefore, under the action of the spring 3, the rotating seat 442 forms a self-locking structure. At the same time, the lower end surface of the lock tongue 443 contacts the upper end surface of the rotating seat 442, further locking the rotating seat 442. By flipping the rotating seat 442, the spring 3 can be quickly tightened. At the same time, the deformation of the spring 3 is at a large extent, exceeding the deformation of the initial setting.

[0029] The support frame 1 includes an annular frame, which is formed by welding of plates. The trampoline processing device includes a frame, and a three-coordinate welding device 6 is configured on the frame. The three-coordinate welding device includes an X-axis moving seat 61, a Y-axis moving seat 62 and a Z-axis moving seat 63. The Z-axis moving seat is configured on the Y-axis moving seat, and the Y-axis moving seat is configured on the X-axis moving seat, thereby realizing three-coordinate movement. A welding seat 64 is configured on the Z-axis moving seat, and a driving member 65 is configured on the welding seat. The driving member is a servo motor, and a rotating plate 66 is connected to the motor shaft of the servo motor. The welding gun 67 is configured on the rotating plate, and then the rotation of the servo motor drives the welding gun to rotate, so that the welding gun can fit the arc surface of the annular frame for welding.

[0030] The annular frame is formed by welding, so there is deformation error. The annular frame is evenly provided with mounting positions of the fixing seat 41. The fixing seat 41 is fixed to the mounting position by bolts. After all the quick-install devices 44 are locked, due to the deformation error, there is a difference in the deformation length of the spring 3. The deformation length difference caused by the deformation error is compensated by adjusting the sliding seat 42.

[0031] A first piston chamber 411 and a second piston chamber 412 are provided in the fixed seat 41. The first piston chamber 411 is located in the middle, and the bottom is connected to the second piston chamber 412 through a first channel 413. A piston ring 414 is provided in the second piston chamber 412 for sliding guidance. A piston rod 421 is provided on the sliding seat 42. The sliding seat 42 is guided and slid in the first piston chamber 411 by the piston rod 421, and a first elastic member 422 is further provided in the first piston chamber 411, the two ends of which respectively touch the lower end of the piston rod 421 and the lower end surface of the first piston chamber 411, thereby enabling the sliding seat 42 to have a driving force to extend forward in the initial state.

[0032] Hydraulic oil is configured under the piston ring 414 of the second piston chamber 412. The hydraulic oil in the two chambers interacts with the hydraulic oil at the bottom of the first piston chamber 411 through the first channel 413 and the second channel 416 respectively, thereby causing the piston rod 421 to extend outward or retract inward. The hydraulic oil in the second piston chamber 412 is used to interact when initially adjusting the length of the spring 3.

[0033] The first channel 413 is provided with a first section groove 4131 and a second section groove 4132. A shutoff plate 4331 is elastically slidably disposed in the first section groove 4131. The movement of the shutoff plate 4331 is controlled by a zipper 434. When the zipper 434 is in a relaxed state, the shutoff plate 4331 blocks the first channel 413. When the zipper 434 is tightened, the first through hole 4332 on the shutoff plate 4331 is aligned with the first channel 413, and this position is unblocked. A switch plate 52 is elastically slidably disposed in the second section groove 4132. The switch plate 52 is controlled by the multi-connector zipper 51. In the initial state, the switch plate 52 blocks the first channel 413. When the zipper is tightened, this position is unblocked. The first channel 413 is controlled by the shutoff plate 4331 and the switch plate 52. Only when both are unblocked can the hydraulic oil in the second piston chamber 412 enter the first piston chamber 411.

[0034] The calibration device 43 includes a telescopic member 431, a top contact rod 432 and a locking device 433. The telescopic member 431 is slidingly guided on the sliding seat 42 so that it can extend in the direction of the spring 3. A second elastic member is arranged in the sliding cavity inside the sliding seat 42, so that the telescopic member 431 has an elastic force to retract into the sliding seat 42 in the initial state. The front end of the telescopic member 431 is slidingly guided up and down with a top contact rod 432. The upper and lower ends of the top contact rod 432 are both provided with magnetic limit blocks, which can be magnetically attracted to the telescopic member 431. At the same time, one end of a hook spring member 4311 is sleeved on the rear end of the telescopic member 431, and the other end of the hook spring member 4311 is sleeved on one end of a zipper, and the other end of the zipper is connected to the intercepting plate 4331, and both ends of the zipper sleeve are arranged on the rear end surface of the fixed seat 41, so that the forward and backward movement of the sliding seat 42 can drive the zipper to tighten or loosen.

[0035] After the rotating seat 442 is flipped and locked, the operator manually pulls out the telescopic part 431, and then lifts the top touch rod 432 upward, so that the limit part at the lower end is magnetically attracted to the telescopic part 431. At this time, the top touch rod 432 is located in the inner ring of the tensioning steel ring on the elastic bed surface 2. At this time, the telescopic part 431 is relaxed, and under the action of the second elastic member, the telescopic part 431 moves toward the sliding seat 42, and then the top touch rod 432 is pressed on the tensioning steel ring. At this time, the zipper is tightened, and then the intercepting plate 4331 presses the elastic part below under the action of the zipper. At the same time, the first through hole 4332 on it is aligned with the first channel 413, so that the channel here is restored to normal.

[0036] The support frame 1 is also provided with a starting unit, which includes a multi-joint zipper 51, a switch plate 52 and a rotary switch. The rotary switch is rotatably configured on the support frame 1. The rotary switch is provided with a capstan. The rotation of the rotary switch drives the capstan to rotate. At the same time, a ratchet is provided on the rotary switch, and a locking tooth is provided on the support frame 1. The two form a ratchet device, so that when the rotary switch rotates forward, the ratchet device automatically locks the rotary switch to prevent it from reversing, and removing the locking tooth allows the rotary switch to be reversed.

[0037] The multi-connector zipper 51 includes a bus 511, to which multiple branch lines 512 are fixedly connected. By pulling the bus 511, all the branch lines 512 can be driven to move synchronously. One end of the bus 511 is configured on the capstan of the rotary switch, and the branch lines 512 are connected to the matching switch plate 52. Turning the rotary switch can wind up the bus 511, thereby tightening the multi-connector zipper 51, causing the switch plate 52 to move, thereby making the first channel 413 unblocked.

[0038] Its working principle or usage is as follows: In the initial state, the sliding seat 42 is in a compressed state, the first elastic member 422 is compressed, and the first channel 413 is blocked, so the sliding seat 42 cannot extend outward, and the quick-install device 44 stretches the spring 3. At this time, the spring 3 is in its longest state. When the spring 3 is initially adjusted, the sliding seat 42 extends forward, thereby reducing the distance between the sliding seat 42 and the tensioning steel ring, thereby shortening the deformation length of the spring 3.

[0039] After the operator pulls out all the telescopic parts 431, the first through holes on all the shutoff plates 4331 are aligned with the first channels 413, and this position is in a smooth state. At this time, the operator turns the rotary switch to open the switch plate 52. At this time, under the action of the spring 2 and the first elastic member 422, the sliding seat 42 extends forward, shortening the distance between the sliding seat 42 and the tensioning steel ring. During the movement of the sliding seat 42, the telescopic part 431 is relatively retracted into the sliding seat 42. When the set length is reached, the zipper controlling the shutoff plate 4331 is in a relaxed state. At this time, the first through hole 4332 on the shutoff plate 4331 is misaligned with the first channel 413, and the first channel 413 is blocked, and the initial length adjustment of the spring 3 at this position is completed.

[0040] The deformation of the frame is adjusted by extending the sliding seat 42 to different lengths so that all springs 3 are at the same deformation length. After all adjustments are completed, that is, when all sliding seats 42 no longer move, the operator manually pushes the top touch rod 432 downward to make the limit display of the top touch rod 432, and the telescopic member 431 retracts to the sliding seat 42 under the action of the elastic member, and then returns to the initial state.

[0041] Example 2:

[0042] See also Figures 1-8 Compared to Example 1, the difference lies in the structure of the fixing base 41; the rest are the same. The support frame 1 is also equipped with an adjustment unit, which includes a second rotary switch and a second multi-joint zipper 53. The second rotary switch is configured similarly to the rotary switch in Example 1, and can rotate unidirectionally under the action of a ratchet device and can reverse when unlocked. The second multi-joint zipper 53 is also similar to the multi-joint zipper in Example 1, with a bus bar mounted on the capstan of the second rotary switch. Rotating the second rotary switch tightens the second multi-joint zipper 53.

[0043] A third piston chamber 415 is also provided in the fixing seat 41. The bottom of the first piston chamber 411 is connected to the third piston chamber 415 through a second channel 416. A piston ring 414 is provided for sliding guidance in the third piston chamber 415. Hydraulic oil is provided under the piston ring 414 of the third piston chamber 415. The hydraulic oil in the third piston chamber 415 is used to adjust the elastic force of the spring 3 during later use. The branch lines of the second multi-head zipper are respectively connected to the upper ends of the piston rings 414 of each fixing seat 41.

[0044] In the initial state, the second multi-joint zipper is in a tightened state, so the piston ring 414 in the third piston chamber 415 will not move downward. Furthermore, when the initial length of the spring 3 in Example 1 is adjusted, the hydraulic oil in the third piston chamber 415 will not enter the first piston chamber 411. After the adjustment of the spring 3 is completed, the first channel 413 is blocked.

[0045] At this time, if it is necessary to increase the elastic force of the trampoline, the second rotary switch is turned, and the piston ring 414 is pulled upward through the second multi-joint zipper, and the hydraulic oil in the first piston chamber 411 is pumped into the third piston chamber 415, thereby moving the sliding seat 42 outward, increasing the distance between the sliding seat 42 and the tensioning steel ring, increasing the deformation of the spring 3, and thus increasing the elastic force of the trampoline.

[0046] When no adjustment is made initially, the trampoline spring force is at its minimum. When it needs to be decreased after being increased, the locking tooth on the second rotary switch is removed, and the second rotary switch is reversed, thereby releasing the tightened second multi-joint zipper. As a result, under the action of the spring 3, the hydraulic pressure flows back from the third piston chamber 415 to the first piston chamber 411, causing the sliding seat 42 to move toward the spring bed surface 2, thereby reducing the trampoline spring force.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
