Description

Technical Field

[0001] The invention belongs to the field of mechanical technology, in particular to a rotating mechanism for outdoor sports and fitness equipment. Background Art

[0002] Existing outdoor sports and fitness equipment is widely used in parks, schools, residential areas and other places with dense populations, bringing health and fun to people's lives. Many outdoor sports and fitness equipment such as seesaws, rings, walkers, etc. use rotating mechanisms, which enable these sports and fitness equipment to rotate relatively, thereby achieving corresponding sports or fitness functions.

[0003] A rotating mechanism for outdoor sports and fitness equipment with application number CN200420047019.3 is provided with a groove for placing an O-ring at a corresponding position on the inner end face of the circular hole of the bearing seat or the outer cylindrical surface of the intermediate sleeve, and the O-ring is placed in the groove. The bearing seat is sealed by the O-ring, so that the bearing in the rotating mechanism has the effect of being waterproof and dustproof during use, thereby avoiding the disadvantage that the bearing is easily damaged and scrapped, and improving the service life of the outdoor sports and fitness equipment. However, when this rotating mechanism is rotating, the internal bearing part will inevitably wear. At this time, external air and water can enter the area where the internal bearing is located through the expansion gap caused by wear, thereby corroding the bearing. At this time, its O-ring will lose its sealing effect, so it needs to be improved. Summary of the invention

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. When in use, the device, as a rotatable connection mechanism, can connect the components at both ends to form a rotating joint, thereby achieving the effect of free rotation. Since the ball axis and the rotating shell at the axis can rotate with each other, and spherical isolation soft sleeves are provided on both sides to isolate the internal balls from the outside world, it is prevented that external air and water can enter the area where the internal bearing is located through the expansion gap caused by wear, thereby avoiding the problem of corrosion of the bearing and causing difficulty in the bearing rotation.

[0013] 2. After installation, the area enclosed by the isolation cover is approximately a sealed space. However, after long-term use, the air outside may gradually penetrate into the interior of the isolation cover. Since the pressure inside the isolation cover will drop due to penetration or leakage, the dehumidifier on the top can be used to actively replace and dry the gas inside the isolation cover to eliminate the corrosive effect caused by water vapor.

[0014] 3. The snap-on bottom shell at the bottom of the device is locked by the bidirectional traction plate to achieve a fixing effect, so the snap-on bottom shell at the bottom can be replaced according to the different connecting components. Since the bottom components connected to the snap-on bottom shell are basically in a relatively static state, the adapter bottom frame is relatively static, and the vertical connecting plate will deflect relative to the adapter bottom frame, thereby achieving the effect of guiding the vertical connecting plate to rotate stably, and the vertical connecting plate is restricted from the side by the adapter bottom frame and the limit end sleeve, and has good resistance to impact force from the side, thereby ensuring the anti-interference ability and strength of the rotating structure.

[0015] 4. The internal damping component can apply appropriate resistance to the deflection of the vertical connecting plate through the round-head push rod, thereby increasing the damping of the vertical connecting plate and preventing the two connected groups of mechanisms from having loose deflection movements, which makes it difficult for users to exercise stably during fitness. The control wheel can also be locked by locking the control wheel, using the raised round-head push rod to clamp the vertical connecting plate, so that the rotating mechanism is in a self-locking state with a certain angle maintained, so that the device will not reset immediately, so that the athlete can stop exercising at any time, and can leave the device without resetting it in a tired state, thereby reducing the load on the athlete.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0025] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a rotating mechanism of outdoor sports and fitness equipment, comprising a rotating shaft component 2, an upper connecting component 1 is arranged on the upper part of the rotating shaft component 2, and a lower connecting component 3 is arranged on the lower part of the rotating shaft component 2;

[0026] The rotating shaft component 2 includes a ball shaft core 21, the outer surface of the ball shaft core 21 is rollingly connected to a rotating shell 22, the ball shaft core 21 and the rotating shell 22 together form a ball bearing, and an annular groove surrounding the rotating shell 22 is opened on both sides of the outer surface of the rotating shell 22, a thick shaft rod 23 is fixedly connected to the axis of the inner cavity of the ball shaft core 21 through a slot, and vertical connecting plates 24 are symmetrically arranged on both sides of the outer surface of the thick shaft rod 23, and both ends of the thick shaft rod 23 are fixedly connected to limited end sleeves 25;

[0027] The upper connecting component 1 includes a accommodating cylinder 11, and the upper part of the inner wall of the accommodating cylinder 11 is evenly provided with clamping claws 12. A dehumidifier 13 is fixedly connected to the axis of the lower surface of the accommodating cylinder 11, and connecting pipes 14 are symmetrically arranged on the left and right sides of the bottom of the inner cavity of the dehumidifier 13. The dehumidifier 13 can extract the gas in the inner surrounding area of ​​the isolation soft sleeve 15 through the connecting pipes 14 and perform heating to achieve a dehumidification effect. The bottom end of the connecting pipe 14 is fixedly connected with the isolation soft sleeve 15, and the inner wall of the isolation soft sleeve 15 is provided with an internal pressure component 4.

[0028] The internal pressure component 4 includes an inner shell 41 attached to the wall, and the inner cavity of the inner shell 41 attached to the wall is evenly provided with sliding sleeves 42 through the through-holes. The bottom end of the sliding sleeve 42 is fixedly connected with a compression connecting tube 43. The compression connecting tube 43 itself has a rebound ability and will undergo elastic deformation when the sliding sleeve 42 moves. The inner wall of the compression connecting tube 43 is slidingly connected with a connecting air tube 44, and the bottom end of the connecting air tube 44 is fixedly connected with a pressure-sensing tube 45. When the sliding sleeve 42 slides along the connecting air tube 44, the air pressure inside the pressure-sensing tube 45 will be changed through the connecting air tube 44.

[0029] There are two isolation sleeves 15. The axis of the inner wall of the isolation sleeve 15 is rotatably connected to the outer surface of the thick shaft rod 23 through an annular groove. The side of the isolation sleeve 15 away from the thick shaft rod 23 is rotatably connected to one side of the outer surface of the rotating shell 22 through a transition groove. The top of the vertical connecting plate 24 is fixedly connected to the lower surface of the accommodating cylinder 11. The bottom end of the pressure-sensing cylinder 45 is fixedly connected to the inner wall of the isolation sleeve 15, and the bottom end of the connecting hollow tube 44 extends to the inside of the pressure-sensing cylinder 45. The outer surface of the compression sleeve 43 and the inner wall of the wall-attached inner shell 41 are pressed against each other, and the outer surface of the wall-attached inner shell 41 is fixedly connected to the inner wall of the isolation sleeve 15.

[0030] The device is a rotating mechanism for connection. The upper component is connected through the clamping claw 12 of the top accommodating cylinder 11, and the lower component is connected through the clamping bottom shell 35 at the bottom. The device's own rotatable property is used as a rotating joint to enable the components connected on the upper and lower sides to rotate relative to each other.

[0031] When rotating, the bottom connecting component is used as a reference object to keep it relatively still. When the upper component rotates, the thick shaft rod 23 will be driven to rotate through the vertical connecting plates 24 on both sides. At this time, the thick shaft rod 23 will directly twist the internal ball shaft core 21, but the external rotating shell 22 will remain relatively still under the restriction of the bottom axial ring 32, so the ball shaft core 21 and the rotating shell 22 will rotate relative to each other, and the friction resistance is greatly reduced through the embedded balls.

[0032] When the ball bearing shaft core 21 and the rotating shell 22 rotate relative to each other, the isolation soft sleeves 15 on both sides will rotate due to the relative rotation of the thick shaft rod 23 and the rotating shell 22, but the isolation soft sleeves 15 always separate the area where the ball bearing shaft core 21 and the inner wall of the rotating shell 22 are located from the outside, thereby preventing external impurities from affecting the internal balls.

[0033] After long-term use, the interior of the isolation soft sleeve 15 may leak due to infiltration and other reasons. At this time, the pressure inside the isolation soft sleeve 15 will decrease, and the sliding sleeve 42 will slide out from the outer surface of the connecting empty pipe 44 under the elastic force of the compression connecting tube 43. After the internal pressure change is fed back by the pressure sensing tube 45, the dehumidifier 13 is started, and the internal area of ​​the isolation soft sleeve 15 is ventilated and dehumidified through the connecting pipes 14 on both sides, so that the environment of the ball shaft core 21 remains in a relatively dry state.

[0034] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of the first embodiment, the lower connecting component 3 includes a transfer bottom frame 31, and grooves connected to the rotating shaft component 2 are reserved on the left and right sides of the transfer bottom frame 31, and an axis ring 32 is fixedly connected to the axis center of the inner wall of the transfer bottom frame 31, and damping components 5 are symmetrically arranged on the left and right sides of the inner wall of the transfer bottom frame 31, and a two-way traction plate 33 is fixedly connected to the axis center of the lower surface of the transfer bottom frame 31, and side slide plates 34 are symmetrically arranged on the left and right sides of the two-way traction plate 33 through pull rods. A clamping bottom shell 35 is arranged at the bottom of the side slide plate 34, and the clamping bottom shell 35 at the bottom can be replaced at any time to connect different components. The clamping bottom shell 35 is locked and fixed by pulling the side slide plates 34 on both sides closer together through the two-way traction plate 33. The axis center of the outer surface of the rotating shell 22 is rotatably connected to the axis center of the inner wall of the adapter bottom frame 31 through an axis ring 32. The left and right sides of the adapter bottom frame 31 are rotatably connected to the outer surface of the limit end sleeve 25 through a sleeve groove. There are two side slides 34, and the upper surface of the side slide 34 is slidably connected to the lower surface of the adapter bottom frame 31 through a guide slide groove.

[0035] The damping component 5 includes a fixed inner shell 51, a control wheel 55 is arranged on one side of the middle of the inner wall of the fixed inner shell 51 near the bottom end of the vertical connecting plate 24, the inner cavity of the control wheel 55 is fixedly connected to a push rod control ring 57, and round-head push rods 56 are evenly arranged in the middle of the inner cavity of the push rod control ring 57. The round-head push rods 56 can slide under the control of the push rod control ring 57, and can bulge outward from the control wheel 55 or shrink to the inside of the control wheel 55, such as Figure 7There are two fixed inner shells 51, the outer surface of the fixed inner shell 51 is fixedly connected to the inner wall of the transfer bottom frame 31, the inner wall of the fixed inner shell 51 is fixedly connected to the side away from the control wheel 55, and the friction wheels 54 are symmetrically arranged on the front and rear sides of the outer surface of the control wheel 55, and the torque motor 53 is fixedly connected to the axis of the friction wheel 54, and the friction wheel 54 directly drives the control wheel 55 in the middle to rotate. The bottom end of the vertical connecting plate 24 is evenly provided with docking grooves 26. The extractor 52 can clean out impurities in the docking groove 26 at the bottom of the vertical connecting plate 24 through the pre-opened hole on the top of the fixed inner shell 51. The end of the round-headed push rod 56 away from the push rod control ring 57 extends to the outside of the control wheel 55 through the through opening, and the end of the round-headed push rod 56 away from the push rod control ring 57 is plugged into the bottom end of the vertical connecting plate 24 through the docking groove 26. The outer surface of the control wheel 55 is rotatably connected to the axis of the inner wall of the fixed inner shell 51, and the outer surface of the torque motor 53 is fixedly connected to the inner wall of the fixed inner shell 51.

[0036] The snap-on bottom shell 35 can be removed from the side slide plate 34 , so when connecting different components, the snap-on bottom shell 35 with different plug-in interfaces can be selected and installed at the bottom of the adapter bottom frame 31 , and then fixed by the two-way traction plate 33 to achieve adaptation.

[0037] Under normal circumstances, the vertical connecting plate 24 will drive the thick shaft rod 23 to rotate. At this time, the bottom of the vertical connecting plate 24 will also rotate relative to the fitting control wheel 55, and the protruding round-head push rod 56 will be driven to rotate by the docking groove. If it is necessary to increase the damping of the rotating mechanism to prevent the two connected groups of mechanisms from having a loose deflection movement, the torque motor 53 can actively twist the friction wheel 54 to prevent the control wheel 55 from passively deflecting with the vertical connecting plate 24, so that the vertical connecting plate 24 is subjected to greater resistance, thereby causing the rotating joint to produce a damping effect. It can also lock the control wheel 55 and use the protruding round-head push rod 56 to clamp the vertical connecting plate 24, so that the rotating mechanism is in a self-locking state maintaining a certain angle.

[0038] Since the bottom end of the vertical connecting plate 24 will be exposed to the outside during the deflection process, dust accumulation and other problems will easily occur in the groove area. In order to avoid corrosion and other problems in the groove of the vertical connecting plate 24, the internal extractor 52 will perform adsorption through the mesh holes on the top of the fixed inner shell 51. When the vertical connecting plate 24 is deflected, its groove will enter the interior of the adapter bottom frame 31, and the dust and impurities will be sucked away by the extractor 52.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
