DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 10 In an embodiment of the present invention, an arc-shaped edge track includes an arc-shaped track body 1, one end of the arc-shaped track body 1 is provided with a mounting groove 8, a positioning block 2 is elastically slidably connected in the mounting groove 8, a connecting rod 3 is fixedly provided on the side wall of the positioning block 2 near one end in the mounting groove 8, the connecting rod 3 slides through the side wall of the arc-shaped track body 1 and extends to the inner ring side wall of the arc-shaped track body 1, and a positioning hole 5 slidably matched with the positioning block 2 is provided at the other end of the arc-shaped track body 1 away from the mounting groove 8, a limiting assembly is provided in the positioning block 2, and a limiting hole 23 slidably matched with the limiting assembly is provided in the positioning hole 5, when the positioning block 2 moves toward and adapts to the positioning hole 5, the limiting assembly moves toward the limiting hole 23 and slidably matches with the limiting hole 23.

[0029] It should be noted that the connecting rod 3 is fixedly set on one side of the positioning block 2 and slides through the side wall of the arc-shaped track body 1 to extend to the inner ring position of the arc-shaped track body 1. Of course, the connecting rod 3 can also be set on the other side of the positioning block 2 and extend to the outer ring side wall of the arc-shaped track body 1. In addition, the mounting groove 8, the positioning block 2, and the positioning hole 5 can also be used on non-arc-shaped tracks and are respectively set at both ends of the track. In this way, when the arc-shaped track body 1 is connected to other tracks, the positioning block 2 corresponds to the position of the positioning hole 5 on the other track, so that the arc-shaped track body 1 can be better adapted and fixed to the other tracks. In actual use, when the arc track body 1 needs to be connected with other tracks, the positioning hole 5 and the positioning block 2 are placed correspondingly, and then the connecting rod 3 is slid to make the positioning block 2 move out of the installation groove 8 and extend into the positioning hole 5, and then the limiting component is adapted to the limiting hole 23 to achieve the adaptation installation of the arc track body 1 and the other tracks, thereby avoiding the problem of relative displacement of the arc track body 1 or other tracks when the arc track body 1 or other tracks are subsequently fixed, so that the arc track body 1 and other track joints always remain corresponding and flush.

[0030] See also Figure 3-Figure 7 Preferably, the limit assembly includes two groups of limit blocks 9; the limit blocks 9 are symmetrically arranged along the center of the positioning block 2, and the two groups of limit blocks 9 are elastically slidably arranged at the upper and lower ends of the positioning block 2, respectively, the limit blocks 9 are slidably adapted to the limit holes 23, and the limit blocks 9 are arranged in the side walls of the positioning block 2 close to the positioning holes 5. When the positioning block 2 slides into the positioning hole 5, the two groups of limit blocks 9 correspond to the positions of the corresponding limit holes 23, and then the limit blocks 9 slide out of the side walls of the positioning block 2 and extend into the limit holes 23, thereby realizing the limitation of the relative positions of the arc track body 1 and other tracks, avoiding the problem that after the arc track body 1 and the adjacent track are aligned and placed, the track may be displaced during the subsequent fixing process by bolts, resulting in the final joint being misaligned, thereby affecting the subsequent use.

[0031] Further, preferably, a fixed plate 11 is fixedly provided in the center of the positioning block 2, and one end of the fixed plate 11 close to the limit block 9 is rotatably connected to a telescopic plate, the telescopic plates are symmetrically arranged along the center of the fixed plate 11, and the telescopic plates are arranged at the upper and lower ends of the fixed plate 11, that is, the telescopic plate corresponds to the limit block 9 one to one, and the end of the telescopic plate away from the fixed plate 11 is rotatably connected to a movable plate 17, and the movable plate 17 is rotatably connected to both sides of the end of the telescopic plate away from the telescopic plate, and the side of the connecting plate 21 away from the movable plate 17 is slidably connected to the side wall of the fixed plate 11. In actual use, a groove is provided at one end of the fixed plate 11 close to the limit block 9, and the telescopic plate, the movable plate 17 and the connecting plate 21 are all arranged in the groove. When the connecting plate 21 is in the end of the fixed plate 11 close to the limit block 9, the rotating connection between the telescopic plate and the movable plate 17 fits with the end of the limit block 9. At this time, the limit block 9 is contracted in the positioning block 2, and the telescopic plate and the movable plate 17 are in a bent state relatively close to the limit block 9. In this way, when the connecting plate 21 moves toward the telescopic plate, the movable plate 17 can be pushed to move in the direction of the telescopic plate. Since the position of the telescopic plate is in a relatively fixed state, the movable plate 17 will rotate in the direction of the limit block 9, so that the limit block 9 moves out of the side wall of the positioning block 2. The cooperation of the telescopic plate and the movable plate 17 realizes the effect of the limit block 9 automatically extending out of the positioning block 2 and adapting to the limit hole 23.

[0032] See also Figure 5 Preferably, the telescopic plate includes an inner plate 19 and an outer plate 18; the inner plate 19 is rotatably connected to the side wall of the fixed plate 11, and the outer plate 18 is sleeved on the periphery of the inner plate 19 away from the fixed plate 11, and one end of the outer plate 18 away from the inner plate 19 is rotatably connected to the movable plate 17. It should be noted that: the maximum rotation angle between the end of the inner plate 19 away from the outer plate 18 and the fixed plate 11 is 0.0447°. After the inner plate 19 is rotated to a vertical state, it cannot be rotated any further. In this way, when the connecting plate 21 continues to move toward the direction of the inner plate 19, it will only cause the movable plate 17 to rotate upward, thereby causing the outer plate 18 to move in a direction away from the inner plate 19, thereby avoiding the problem that after the inner plate 19 is rotated to a vertical state, it can continue to rotate, thereby failing to realize the movable plate 17 and the outer plate 18 pushing the limit block 9 to move.

[0033] See also Figure 2-Figure 7Preferably, a straight plate 13 is slidably provided at the center of the fixed plate 11, and an elastic rope 20 is fixedly provided between the connecting plate 21 and the straight plate 13, and the end of the straight plate 13 away from the connecting plate 21 is slidably connected to the wedge block 12, and an elastic block 4 is provided at the end of the mounting groove 8 away from the positioning block 2, and a notch 41 is provided at the end of the elastic block 4 close to the positioning block 2, and a stopper 42 is fixedly provided at the bottom of the notch 41 close to the positioning block 2. In actual use, the wedge block 12 and the straight plate 13 are elastically slidably connected by a spring, and the bottom end of the wedge block 12 is provided with an inclined surface facing the elastic block 4, the elastic block 4 is elastically connected to the inner wall of the arc track body 1 by a spring, and one end of the elastic block 4 extends to the inner ring side wall of the arc track body 1, and there is a gap (recorded as a avoidance opening) between the end of the stopper 42 close to the inner ring of the arc track body 1 and the notch 41.

[0034] When in use, in the initial state, the positioning block 2 is retracted in the installation groove 8, and the top of the wedge block 12 is flush with the top of the straight plate 13 under the action of the corresponding spring. Under the action of the corresponding spring, the end of the spring block 4 away from the spring is flush with the inner ring side wall of the arc track body 1, and the wedge block 12 is in the notch 41 and fits with the side of the stopper 42 away from the positioning block 2, thereby limiting the relative position of the straight plate 13, and the corresponding connecting plate 21 is at the end of the fixed plate 11 away from the spring block 4; when the sliding connecting rod 3 makes the positioning block 2 move out of the installation groove 8 to adapt to the positioning holes 5 on other rails, in this process, since the wedge block 12 is adapted to the stopper 42, the positions of the wedge block 12 and the straight plate 13 are relatively fixed, and then when the positioning block 2 moves, the straight plate 13 is in a relatively fixed position, so that the elastic rope 20 is stretched, and then the elastic rope 20 makes the connecting plate 21 move toward the straight plate 13, and the movement of the connecting plate 21 makes the movable plate 17 move toward the telescopic plate. When the fixing of the arc track body 1 and the other tracks is needed to be released, the spring block 4 is pressed into the arc track body 1, so that the spring block 4 moves into the arc track body 1, and then the stop block 42 moves and separates from the wedge block 12, that is, the wedge block 12 slides relatively to the spring block 4 to the avoidance position, at this time, the elastic rope 20 elastically resets and pulls the straight plate 13 to reset, and there is no force between the movable plate 17 and the telescopic plate, and then the limit block 9 moves and shrinks in the positioning block 2 under the corresponding elastic action. In this process, the limit block 9 moves and resets, which pushes the movable plate 17 and the telescopic plate to rotate and reset, thereby causing the connecting plate 21 to move and reset, and when the limit block 9 is separated from the limit hole 23, the fixed limit between the arc track body 1 and the other tracks is released.

[0035] See also Figure 5-Figure 10Preferably, a bayonet 22 is provided on one side of the limit block 9, and the bayonet 22 is provided on the side of the limit block 9 away from the straight plate 13. A buckle plate 15 is elastically connected to the side wall of the positioning block 2 through a spring, and blocks that are slidably adapted to the bayonet 22 are provided at both ends of the side of the buckle plate 15 close to the limit block 9.

[0036] Further, preferably, pushing blocks 16 are slidably fitted on both sides of the center of the buckle plate 15, and the pushing blocks 16 are slidably set in the side walls of the positioning block 2. An extension rod is fixedly set on the side wall of the pushing block 16 away from the buckle plate 15, and the extension rod is set on the side of the pushing block 16 away from the limit block 9, and the end of the extension rod away from the pushing block 16 is fixedly connected with a pushing rod 10, and the end of the pushing rod 10 away from the buckle plate 15 slides out of the side wall of the positioning block 2, a semicircular groove 6 corresponding to the pushing rod 10 is provided in the mounting groove 8, and a matching groove 24 corresponding to the pushing rod 10 is provided in the positioning hole 5.

[0037] In actual use, the end of the card block away from the buckle plate 15 is provided with a slope facing the periphery of the positioning block 2, and the side of the pushing block 16 close to the buckle plate 15 is provided with a slope facing the buckle plate 15. The pushing rod 10 is a cylindrical structure, and the end of the pushing rod 10 protruding from the positioning block 2 is a semicircular structure; in the initial state, the limit block 9 is retracted in the side wall of the positioning block 2, at which time the bayonet 22 and the card block slide in cooperation, and then through the inclined surface of the pushing block 16, the pushing rod 10 protrudes from the side wall of the positioning block 2 and is in the semicircular groove 6, and the end of the matching groove 24 close to the limiting hole 23 is provided with a slope connected to the inner wall of the positioning hole 5, and the length of the matching groove 24 is the distance after the positioning block 2 is extended into the positioning hole 5 and one side of the limiting block 9 also extends into the positioning hole 5; when the positioning block 2 is moved into the positioning hole 5 During movement, the positioning block 2 moves and drives the pushing rod 10 to move and separate from the semicircular groove 6. Then, the pushing rod 10 moves and retracts into the positioning block 2 under the action of the matching groove 24. At this time, the movement of the pushing rod 10 pushes the pushing block 16 to move toward the buckle plate 15, and then the buckle plate 15 is moved away from the limit block 9 through the inclined surface of the pushing block 16, so that the card block is separated from the bayonet 22, and the restriction on the limit block 9 is released. Then, when the positioning block 2 moves so that the limit block 9 corresponds to the limit hole 23, the limit block 9 moves into the limit hole 23 under the action of the movable plate 17. The setting of the card block avoids the problem that when the limit block 9 extends out of the installation groove 8 with the positioning block 2 and does not move to extend into the positioning hole 5, the moving protruding positioning block 2 causes the positioning block 2 to no longer be able to move into the positioning hole 5.

[0038] See also Figure 1-Figure 2 , Figure 4Preferably, a storage chamber is provided in the end of the positioning block 2, and the storage chamber is provided at a position corresponding to the push rod 10. A piston plate 14 is provided in the storage chamber along the central symmetrical sealing sliding, and the piston plate 14 is fixedly connected to the push rod 10 on the side close to the push rod 10. A nozzle 7 connected to the storage chamber is provided at the end of the positioning block 2 away from the connecting rod 3. In actual use, the storage chamber can be injected with a lubricating liquid for lubricating the positioning block 2 and the positioning hole 5, and the nozzle 7 can be set according to the actual required position. When the end of the positioning block 2 is extended into the positioning hole 5, After the push rod 10 contracts into the positioning block 2 under the action of the matching groove 24, the movement of the push rod 10 will push the piston plate 14 closer, thereby squeezing the lubricating liquid in the storage cavity between the piston plates 14, and then spraying it out through the nozzle 7, so that the positioning hole 5 is lubricated. In this way, when the positioning block 2 extends into the positioning hole 5, no large friction will occur, reducing the wear of the positioning hole 5 or the positioning block 2, allowing the positioning hole 5 and the positioning block 2 to always maintain a close sliding fit, thereby improving the accuracy of the arc track body 1 and other track joints.
