[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1What is shown is a three-dimensional schematic diagram of the roller ring in the embodiment; Figure 2 Shown is a schematic cross-sectional view of a roller ring in an embodiment; Figure 3 It is shown that Figure 2 A is an enlarged schematic diagram;

[0024] The device includes:

[0025] Outer ring 1;

[0026] Inner ring 2;

[0027] The connecting structure 10 includes a groove 12 provided on the inner ring 2 and a protrusion 11 provided on the outer ring 1 and matching with the groove 12, a mounting groove 13 provided on the protrusion 11, an inserting block 15 movably provided in the mounting groove 13, a slot 14 communicating with the mounting groove 13 provided on the side wall of the groove 12, the inserting block 15 movably plugged with the slot 14, and an adjusting component provided on the protrusion 11 and connected with the inserting block 15;

[0028] The adjusting component controls the plug-in block 15 to enter the slot 14 so that the outer ring 1 and the inner ring 2 are connected, and the adjusting component controls the plug-in block 15 to leave the slot 14 so that the outer ring 1 and the inner ring 2 can be separated.

[0029] The connection structure 10 is symmetrically arranged in two groups;

[0030] The adjustment component controls the position of the insert block 15. When the insert block 15 enters the slot 14, the outer ring 1 and the inner ring 2 are connected. When the insert block 15 leaves the slot 14 and enters the installation groove 13, the outer ring 1 and the inner ring 2 can be disassembled and separated.

[0031] By setting mutually matching protrusions 11, grooves 12, inserts 15 and slots 14, the outer ring 1 and the inner ring 2 can be disassembled, so that when any one of the outer ring 1 and the inner ring 2 is worn or damaged, it can be removed and replaced without replacing the entire roller ring, thereby reducing the use cost of the roller ring.

[0032] like Figure 3 As shown, Figure 3 It is shown that Figure 2 A is an enlarged schematic diagram;

[0033] Specifically, the mounting groove 13 is set to be L-shaped and includes a horizontal section and a vertical section. The plug block 15 is movably set in the horizontal section of the mounting groove 13, and the slot 14 is set in the groove 12 at a position corresponding to the horizontal section of the mounting groove 13;

[0034] The adjustment assembly includes a fixed plate 21 arranged in the horizontal section of the installation slot 13, a guide rod 22 is arranged at one end of the plug block 15 away from the slot 14, the guide rod 22 movably passes through the fixed plate 21 and the extended end is provided with the same connecting plate, a spring 23 is sleeved on the outer portion of the guide rod 22 located between the fixed plate 21 and the plug block 15, and the two ends of the spring 23 are fixedly connected to the fixed plate 21 and the plug block 15 respectively;

[0035] It also includes a traction member, one end of which is connected to the connecting plate, and the other end of which extends to the top of the vertical section of the installation groove 13.

[0036] The guide rods 22 are arranged in two symmetrical ways, both of which are horizontally and movably inserted on the fixed plate 21, so as to guide the movement of the plug block 15, and the connecting plate is arranged so that the plug block 15 will not be separated from the fixed plate 21. The plug block 15 moves in the direction close to the fixed plate 21 until it is completely inserted into the installation groove 13, and the plug block 15 moves in the direction away from the fixed plate 21 until it is completely inserted into the slot 14;

[0037] In the absence of external force, the spring 23 in normal state pushes the insert 15 into the slot 14 to achieve a stable connection between the outer ring 1 and the inner ring 2. By applying external force to the traction member, the spring 23 can be compressed and the insert 15 can be moved out of the slot 14 until the outer ring 1 and the inner ring 2 can be separated smoothly.

[0038] The traction member includes a traction rope 24 connected to the connecting plate, and a fixed pulley 25 located in the overlapping area of ​​the horizontal section and the vertical section of the installation groove 13. The other end of the traction rope 24 bypasses the fixed pulley 25 and extends into the vertical section and is connected to a pull rod 26.

[0039] The traction rope 24 and the pull rod 26 both play the role of pulling the plug block 15 to move its position, and the fixed pulley 25 plays the role of changing the direction of the force of the traction rope 24; the top end of the pull rod 26 is close to the open end of the horizontal vertical section of the installation groove 13, and the top end of the pull rod 26 is also provided with a handle for easy grip;

[0040] By holding the handle and lifting the pull rod 26 upward, the insertion block 15 can be disengaged from the slot 14.

[0041] Working principle: When it is necessary to replace either the outer ring 1 or the inner ring 2, lift the pull rod 26 upwards by holding the handle. The pull rod 26 moves the plug block 15 toward the fixed plate 21 through the traction rope 24 until it is out of the slot 14 and completely enters the installation slot 13. At this time, the outer ring 1 or the inner ring 2 can be disassembled. During installation, the pull rod 26 is also used to move the plug block 15 into the installation slot 13, and then the outer ring 1 and the inner ring 2 are correctly assembled through the protrusion 11 and the groove 12. After assembly, remove the external force applied to the pull rod 26. Under the action of the spring 23, the plug block 15 moves away from the fixed plate 21 and enters the slot 14, realizing the assembly connection between the two.

[0042] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
