A type of sports equipment with shock absorption device

Abstract

This utility model relates to a sports equipment with a shock-absorbing device applied in the field of sports equipment technology. First, after laying a rubber pad on the sound insulation board, adjust one side of the lightweight treadmill. Hold the handle and rotate the connecting block clockwise, which drives the threaded rod to rotate at the movable end of the telescopic rod, causing the treadmill to move down. At the same time, the first shock-absorbing spring is compressed to change the elastic coefficient. With the help of the rotating design of the connecting shaft between the support plate and the clamping plate, the side tilt can be adjusted. The other side is adjusted in the same way. Rotating the connecting block counterclockwise will raise the treadmill. When in use, if it is necessary to adapt to the exercise intensity, align the slider and the locking shaft of the secondary shock-absorbing mechanism with the sliding groove and the locking groove respectively and insert them vertically. Install them between the treadmill and the sound insulation board, ensuring that the connecting plate is completely fitted and the mechanism is evenly distributed to enhance the cushioning and shock absorption effect. The silicone sleeves outside the first and second shock-absorbing springs can reduce metal collision noise. The secondary shock-absorbing mechanism can achieve adaptive fine adjustment through the rotational connection between the locking shaft and the treadmill.

Description

Technical Field

[0001] This utility model relates to a type of sports equipment, and more particularly to a type of sports equipment with a shock-absorbing device applied in the field of sports equipment technology. Background Technology

[0002] Treadmills are a common type of indoor exercise equipment and are very popular among fitness enthusiasts. However, when using a treadmill, it generates significant vibrations that can affect the surrounding environment. Most treadmills on the market are equipped with simple vibration damping structures, such as springs or rubber pads at the bottom of the running platform.

[0003] Chinese patent CN218607978U discloses a type of sports equipment. This utility model can convert the speed signal of the sports equipment into vibrations or buzzers that the user can feel, thus preventing the user's gaze from being diverted and improving the safety of the sports equipment.

[0004] Chinese patent CN208193605U discloses a type of sports equipment. Compared with similar sports equipment in the past, this utility model has the advantages of being lightweight, durable, not easily damaged by collisions, and easy to transport.

[0005] Currently, lightweight home treadmills (like the EasyRun M1 Pro) have fixed spring or rubber pad elasticity coefficients, making it impossible to adjust them according to the runner's weight, running speed, or other factors, resulting in poor shock absorption. Utility Model Content

[0006] The technical problem that this utility model aims to solve in response to the above-mentioned prior art is that the elastic coefficient of the springs or rubber pads in current household lightweight treadmills is fixed and cannot be adjusted according to factors such as the runner's weight and running speed, resulting in poor shock absorption.

[0007] To address the aforementioned problems, this utility model provides a sports equipment with a shock-absorbing device, including a treadmill body. A main shock-absorbing mechanism is installed at each of the four corners of the treadmill body's bottom. Each main shock-absorbing mechanism includes a telescopic rod installed at one of the four corners of the treadmill body's bottom. The movable end of the telescopic rod has a threaded hole, and a threaded rod is threaded into the threaded hole. A connecting block with a handle is fixedly connected to the top of the threaded rod. Two sets of clamping plates are symmetrically fixedly connected to the front and rear sides of the treadmill body's bottom. A support plate is rotatably connected to the inner wall of each clamping plate via a connecting shaft. Two connecting blocks on the same side are rotatably connected to the bottom of the support plate. A first shock-absorbing spring is sleeved on the surface of the telescopic rod, and a sound-insulating plate is fixedly connected to the bottom of the telescopic rod. The two ends of the first shock-absorbing spring... The treadmill body is fixedly connected to the connecting block and the sound insulation plate respectively. The bottom of the sound insulation plate is detachably connected to a rubber pad. The bottom of the treadmill body is detachably connected to multiple secondary vibration damping mechanisms at equal intervals between the main vibration damping mechanisms. The secondary vibration damping mechanisms include multiple sliding grooves equidistantly opened on the top of the sound insulation plate. A set of symmetrical connecting plates are slidably connected in the sliding grooves. Multiple second vibration damping springs are fixedly connected at equal intervals between two connecting plates. The upper connecting plate abuts against the bottom of the treadmill body. The bottom of the lower connecting plate is fixedly connected to a slider, and the slider engages with the sliding groove. The bottom of the treadmill body is provided with slots corresponding to the multiple sliding grooves at equal intervals. The top of the upper connecting plate is fixedly connected to a locking shaft that matches the locking groove, and the locking shaft engages with the locking groove.

[0008] In the aforementioned sports equipment, multiple main damping mechanisms are first set up to roughly adjust the elastic coefficient according to the user's condition, and then the secondary damping mechanisms are used for precise adjustment until the best damping effect is achieved.

[0009] As a further supplement to this application, a certain gap is left between the support plate and the bottom of the treadmill body to allow the support plate to rotate within a 45° range.

[0010] As a further supplement to this application, both the first damping spring and the second damping spring are fitted with silicone sleeves.

[0011] As a further supplement to this application, a fixed plate is fixedly connected to each of the four corners of the side of the treadmill body, near the main shock absorption mechanism, and a movable plate is connected to the lower outer end of the fixed plate by screw threads.

[0012] As a further supplement to this application, the outer end of the active plate is rotatably connected to a roller via a pivot, and the distance between the roller and the bottom of the treadmill body is less than the height when the preload of the first damping spring is at its maximum value.

[0013] As a further supplement to this application, a storage cabinet with a cover is placed on the side of the treadmill body, and a spare secondary shock absorption mechanism is placed inside the storage cabinet.

[0014] In summary, first place the rubber pad on the sound insulation board. Then, adjust one side of the lightweight treadmill body. Hold the handle and rotate the connecting block clockwise. This causes the connecting block to rotate the threaded rod within the movable end of the telescopic rod, thus lowering the treadmill body. During this downward movement, the first shock-absorbing spring is compressed, changing its elastic coefficient. The support plate, through the rotating connection design between the connecting shaft and the clamping plate, allows the treadmill body to tilt when adjusting one side. After adjusting one side, adjust the other side of the treadmill body in the same way. To raise it, rotate the connecting block counterclockwise. The connecting plate allows the treadmill body to be installed between the treadmill body and the sound insulation board by aligning the slider of the secondary shock absorption mechanism with the slide groove and inserting the retaining shaft vertically into the groove, according to the exercise intensity requirements. After installation, check whether the connecting plate is completely in contact with the bottom surface of the treadmill body and the surface of the sound insulation board, and ensure that multiple secondary shock absorption mechanisms are evenly distributed to achieve a buffering and shock absorption effect. The silicone sleeves on the surfaces of the first and second shock absorption springs effectively reduce metal collision noise. The secondary shock absorption mechanism can achieve adaptive fine adjustment during use through the rotating connection design of the retaining shaft and the treadmill body.

[0017] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0018] First implementation method: Figures 1-7 The diagram illustrates a sports equipment with a shock absorption device, comprising a treadmill body 1. A main shock absorption mechanism is installed at each of the four corners of the bottom of the treadmill body 1. Each main shock absorption mechanism includes a telescopic rod 14 installed at one of the four corners of the bottom of the treadmill body 1. The movable end of the telescopic rod 14 has a threaded hole, and a threaded rod 6 is threaded into the threaded hole. A connecting block 7 with a handle 16 is fixedly connected to the top of the threaded rod 6. Two sets of clamping plates 24 are symmetrically fixedly connected to the front and rear sides of the bottom of the treadmill body 1. A support plate 19 is rotatably connected to the inner wall of each set of clamping plates 24 via a connecting shaft 15. A round block is fixedly connected to the top of each of the two connecting blocks 7 on the same side. The bottom of the support plate 19 has symmetrically formed grooves corresponding to the two round blocks, and the round blocks are rotatably connected to the grooves. A first shock-absorbing spring 5 is sleeved on the surface of the telescopic rod 14. A sound-insulating plate 3 is fixedly connected to the bottom of the telescopic rod 14. The two ends of the spring 5 are fixedly connected to the connecting block 7 and the sound insulation plate 3 respectively. The bottom end of the sound insulation plate 3 is detachably connected to the rubber pad 2. The bottom end of the treadmill body 1 is detachably connected to multiple secondary damping mechanisms at equal intervals between the main damping mechanisms. The secondary damping mechanisms include multiple sliding grooves 11 equidistantly opened at the top of the sound insulation plate 3. A set of symmetrical connecting plates 12 are slidably connected in the sliding grooves 11. Multiple second damping springs 8 are fixedly connected at equal intervals between the two connecting plates 12. The upper connecting plate 12 abuts against the bottom end of the treadmill body 1. The bottom end of the lower connecting plate 12 is fixedly connected to the slider 13, and the slider 13 is engaged with the sliding groove 11. The bottom end of the treadmill body 1 is provided with slots 22 corresponding to the multiple sliding grooves 11 at equal intervals. The top end of the upper connecting plate 12 is fixedly connected to the slot 22 and the slot 23 is engaged with the slot 22. A certain gap is left between the support plate 19 and the bottom of the treadmill body 1 to allow the support plate 19 to rotate within a 45° range. The surfaces of the first damping spring 5 and the second damping spring 8 are both covered with silicone sleeves 17.

[0019] Working principle: First, place the rubber pad 2 on the sound insulation board 3. Then, adjust one side of the lightweight treadmill body 1 (EasyRun M1 Pro). Hold the handle 16 and rotate the connecting block 7 clockwise. At this time, the connecting block 7 drives the threaded rod 6 to rotate within the movable end of the telescopic rod 14, thereby moving it downwards. This causes the treadmill body 1 to move downwards for adjustment. During the downward movement, the first shock-absorbing spring 5 is compressed, thereby changing the elastic coefficient. The support plate 19 is connected to the clamping plate 24 via the connecting shaft 15, allowing the treadmill body 1 to tilt when adjusting one side. After adjusting one side, adjust the other side of the treadmill body 1 in the same way. To raise it, rotate counterclockwise. The pin-rotating connecting block 7 allows the treadmill body 1 to align the slider 13 of the secondary damping mechanism with the slide groove 11 and the locking shaft 23 with the locking groove 22 during use, according to the exercise intensity requirements. This vertically inserts the secondary damping mechanism between the treadmill body 1 and the sound insulation plate 3. After installation, check whether the connecting plate 12 is completely in contact with the bottom surface of the treadmill body 1 and the surface of the sound insulation plate 3, and ensure that multiple secondary damping mechanisms are evenly distributed to achieve a buffering and damping effect. The silicone sleeve 17 on the surface of the first damping spring 5 and the second damping spring 8 effectively reduces metal collision noise. The secondary damping mechanism can achieve adaptive fine adjustment during use through the rotating connection design of the locking shaft 23 with the treadmill body 1. This invention features multiple main damping mechanisms, allowing users to first roughly adjust the elastic coefficient according to their own situation, and then precisely adjust it through the secondary damping mechanisms until the best damping effect is achieved.

[0020] Second implementation method: Figures 1-3 As shown, fixed plates 9 are fixedly connected to the four corners of the side of the treadmill body 1, near the main shock absorption mechanism. A movable plate 10 is threadedly connected to the lower outer end of the fixed plate 9 by screws 18. A roller 4 is rotatably connected to the outer end of the movable plate 10 by a rotating shaft. The distance between the roller 4 and the bottom of the treadmill body 1 is less than the height when the preload of the first shock absorption spring 5 is at its maximum. A storage cabinet 20 with a cabinet cover 21 is placed on the side of the treadmill body 1. A spare auxiliary shock absorption mechanism is placed inside the storage cabinet 20. This device is selectively provided by the technical field.

[0021] Working principle: After the treadmill body 1 is moved to a suitable position by the rollers 4, the main shock absorption mechanism is first adjusted to the maximum preload so that the rollers 4 are off the ground. At this time, the screws 18 can be turned to rotate the movable plate 10 to fit against the side of the treadmill body 1, so as not to affect the shock absorption effect on the treadmill body 1. Then the main shock absorption mechanism is adjusted. After multiple secondary shock absorption mechanisms are installed on the treadmill body 1 according to actual use needs, the remaining secondary shock absorption mechanisms can be placed in the storage cabinet 20 by opening the cabinet cover 21, so that they can be easily retrieved for the next use. The storage cabinet 20 can also be used as a stool, so that when the exerciser is tired, he can sit on the storage cabinet 20 to rest. This utility model uses rollers 4 to facilitate the movement of the treadmill body 1 while also assisting in the adjustment of the shock absorption mechanism. In addition, a storage cabinet 20 is provided on the treadmill body 1 to store the shock absorption mechanism and also to serve as a seat.

[0022] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
