Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment, specifically relating to a roller glider. Background Technology

[0002] Roller gliders consist of a roller glider and a gliding track. The rider is secured to the roller glider via safety straps. The rollers of the roller glider roll in conjunction with the gliding track, utilizing the elevation difference of the track to power the roller glider's movement. Current roller gliders generally use a set of coaxial double rollers in conjunction with two parallel tracks. Their main drawbacks are: when gliding through curves, the centripetal force generated by the rider's weight can easily cause the roller glider to wobble radially along the track, resulting in poor gliding stability; radial wobble causes excessive stress on one roller, leading to excessive wear on that roller and causing the roller glider to lose its smooth gliding function; the roller axle experiences significant stress during gliding, resulting in rapid roller wear, easy damage to the roller axle, and a short product lifespan. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a roller glider with good roller-track compatibility, good gliding stability, reduced roller wear, prevention of roller shaft damage, and effective extension of service life.

[0004] The technical solution for realizing this utility model is as follows: A roller glider includes a gliding track and a roller glider. The gliding track includes two parallel rails. The roller glider includes a glider body and two rollers symmetrically mounted on roller shafts on both sides of the glider body. The glider body is located between the two rails, and the rollers on both sides roll in cooperation with the two rails respectively. A safety strap connection port is provided at the lower end of the glider body. The glider track is characterized by having a second rail, which is composed of two parallel rails and is located directly above the second rail. A self-lubricating disc is provided at the upper end of the glider body, and the lower plane of the self-lubricating disc slides in cooperation with the upper circular surface of the second rail.

[0005] A preferred embodiment is that a cylindrical bearing is provided between the inner hole of the roller and the outer cylindrical surface of the roller shaft to form a roller assembly. The roller assembly is axially mounted on the roller shaft by an internal hexagon screw, so that the roller assembly can rotate on the roller shaft. A retaining spring is built between the roller assembly and the roller shaft to form an axial floating structure between the roller assembly and the roller shaft.

[0006] A preferred embodiment is that the self-lubricating slide is mounted on the outer cylindrical surface of the round steel tube at the upper end of the slide body, a limiting bushing is provided on the outer cylindrical surface of the round steel tube between the lower end face of the self-lubricating slide and the slide body, an upper limit plate is provided on the round steel tube at the upper end face of the self-lubricating slide, and a spring is provided between the upper limit plate and the self-lubricating slide.

[0007] The preferred embodiment is that the glider body is composed of clamping plates set on the outer circumference of a round steel tube, and the roller shaft is welded to the round steel tube to form a cross structure. The clamping plates are composed of a left clamping plate and a right clamping plate. The left clamping plate and the right clamping plate are respectively provided with shaft holes and several countersunk mounting holes. The shaft holes of the left clamping plate and the right clamping plate are inserted from both ends of the roller shaft. Hex bolts and nuts are installed in the countersunk mounting holes of the left clamping plate and the right clamping plate to fix the two together.

[0008] Compared with the prior art, the beneficial effects of this utility model are that the sliding track is composed of a second sliding track set above the sliding track, and the roller slide is composed of rollers that roll with the sliding track and self-lubricating slide plates that slide with the second sliding track. During the sliding process, the load on the rollers and roller shafts is reduced, the left and right sway of the slide body is reduced, and the sliding stability of the slide body is improved. It has the advantages of stable sliding, low wear of rollers and roller shafts, and long service life. Attached Figure Description

Detailed Implementation

[0012] like Figure 1 , Figure 2The roller glider shown includes a gliding track and a roller glider 1. The gliding track includes two parallel rails 2. The roller glider 1 includes a glider body and two rollers 104 symmetrically mounted on roller shafts on both sides of the glider body. The glider body is located between the two rails 2, and the rollers 104 on both sides roll in contact with the two rails 2 respectively. The rails 2 are made of stainless steel pipes, and the rollers 104 are made of nylon material with good lubrication properties to reduce the friction between them and the rails 2. A safety strap connection port 112 is provided at the lower end of the glider body. The gliding track is fixedly mounted on the track mounting pipe 5 by several mounting plates 5. The gliding track has a height difference to provide gliding potential energy for the glider. Its characteristic is that the gliding track is equipped with a second roller... The second slide rail 3 consists of two parallel tracks and is located directly above the slide rail 2. The second slide rail 3 and the slide rail 2 are arranged vertically parallel to each other. A self-lubricating slide plate 109 is provided at the upper end of the slide body. The lower plane of the self-lubricating slide plate 109 slides in contact with the upper cylindrical surface of the second slide rail 3. The self-lubricating slide plate 109 is made of nylon. Through reasonable design, during the sliding process, while the roller 104 rolls on the slide rail 2, the lower plane of the self-lubricating slide plate 109 slides in contact with the upper cylindrical surface of the second slide rail 3, which improves the sliding stability of the roller slide 1, keeps the two rollers 104 in simultaneous rolling contact with the two slide rails 2, and prevents the single roller 104 from rolling and sliding due to side overturning on the curve, which would lead to different wear between the two rollers 104 and affect the service life of the product.

[0013] A cylindrical bearing 102 is installed between the inner hole of the roller 104 and the outer cylindrical surface of the roller shaft, forming a roller assembly. The roller assembly is axially positioned on the roller shaft by an internal hexagonal screw 103. A retaining spring is built between the roller assembly and the roller shaft, creating an axially floating structure. During sliding, the rollers 104 on both sides can move axially along the roller shaft, automatically compensating for the distance deviation between the two slide rails 2 and reducing sliding resistance. Figure 2 As shown.

[0014] The self-lubricating slide plate 109 is mounted on the outer cylindrical surface of a round steel tube at the upper end of the slide body. A limiting sleeve 110 is provided on the outer cylindrical surface of the round steel tube between the lower end face of the self-lubricating slide plate 109 and the slide body. An upper limiting plate 106 is provided on the round steel tube at the upper end face of the self-lubricating slide plate 109. The upper limiting plate 106 is fixedly mounted on the upper end of the round steel tube. The self-lubricating slide plate 109 has a small axial displacement between the upper limiting plate 106 and the limiting sleeve 110. A spring is provided between the upper limiting plate 106 and the self-lubricating slide plate 109. During the sliding process, the spring presses the self-lubricating slide plate 109 into contact with the second slide rail 3, automatically compensating for the distance deviation between the slide rail 2 and the second slide rail 3. Figure 2 As shown.

[0015] The glider body is composed of clamping plates 101 set on the outer circumference of a round steel tube. The roller shaft is welded to the round steel tube to form a cross structure. The clamping plate 101 consists of a left clamping plate and a right clamping plate. The left and right clamping plates are respectively provided with shaft holes and several countersunk mounting holes 111. The shaft holes of the left and right clamping plates are inserted from both ends of the roller shaft. Hexagonal socket head cap screws and nuts are installed in the countersunk mounting holes 111 of the left and right clamping plates to fix them together. The countersunk mounting holes 111 are numerous, ensuring reliable fixation of the left and right clamping plates. Figure 2 As shown.

[0016] An upper cover plate 108 is installed on the upper surface of the upper limit plate 106, and a middle cover plate 105 is provided at the upper end of the clamping plate 101. Two wire rope through holes 107 are provided on the upper cover plate 108. The two ends of the stainless steel wire rope are passed through the two wire rope through holes 107 and the inner hole of the round steel pipe and connected to the two safety strap connection ports 112 to improve the reliability of the safety straps. Figure 1 As shown.
