Corresponding to fig. 1, the upper and lower inner rotating members 4 are respectively located at the upper and lower sides of the chain unit 3, and the upper and lower outer rotating members 6 are respectively located at the inner top wall and the inner bottom wall of the base 1.

The limiting component 7 enables the middle rotating piece 5 and the upper and lower outer rotating pieces 6 not to deviate on the base 1 at will, and the limiting component 7 is matched with the chain monomer 3 so that the upper and lower inner rotating pieces 4 cannot deviate on the base 1 at will, and further the inner rotating piece 4, the middle rotating piece 5 and the outer rotating pieces 6 can keep a joint state with a track all the time.
Still further, the top surface of the base 1 is provided with a top groove 103, and a control component 8 for driving the limiting component 7 to move is arranged in the top groove 103; in particular, the control assembly 8 is liftable up and down along the base 1. When the control assembly 8 is positioned below, the limiting assembly 7 can realize the limiting of the middle rotating piece 5 and the outer rotating piece 6 and cooperate with the chain monomer 3 to realize the limiting of the inner rotating piece 4; when the control assembly 8 is lifted up, the limiting assembly 7 correspondingly moves so that the inner rotating member 4, the rotating member 5 and the outer rotating member 6 are all released from the limit.
In this embodiment, the inner rotating member 4, the rotating member 5, and the outer rotating member 6 may be hollow rotating members such as existing bearings or rollers, which are themselves rotatable and hollow inside may be fixed, which is a conventional mature technology and will not be described in detail herein.
Referring to fig. 4 to 7, in the present embodiment, it is preferable that: the limiting assembly 7 comprises a first strut 701, a second strut 702, a third strut 704 and two fourth struts 706 fixedly mounted on the base 1, wherein the first strut 701 and the second strut 702 are respectively used for limiting the upper and lower rows of inner rotating members 4, the third strut 704 is used for limiting the middle rotating member 5, the two fourth struts 706 are used for limiting the upper and lower rows of outer rotating members 6, and therefore the two fourth struts 706 are correspondingly mounted on the inner top wall and the inner bottom wall of the base 1.

Specifically, the first pillar 701 cooperates with the top surface of the step 101 and the top surface of the chain monomer 3 to realize the limitation of the upper inner rotator 4, the second pillar 702 cooperates with the bottom surface of the step 101 and the bottom surface of the chain monomer 3 to realize the limitation of the lower inner rotator 4, the third pillar 704 cooperates with the left and right inner walls of the opening 102 to realize the limitation of the middle rotator 5, and the fourth pillar 706 cooperates with the protrusion 707 and the inner top wall/inner bottom wall of the base 1 to realize the limitation of the upper outer rotator 6/lower outer rotator 6.
In the above-described structure, the first spring 703 causes the second leg 702 to have a tendency to move upward relative to the base 1, so that the third leg 704 has a tendency to move away from the clip 2 relative to the base 1, and the second spring 705 causes the bump 707 to have a tendency to protrude relative to the fourth leg 706. When the control assembly 8 is started, the first support 701 is driven to rise, the second support 702 is driven to descend, the third support 704 is driven to move towards the direction of the clamping block 2, and the protruding block 707 is driven to retract into the fourth support 706, so that the limit of the inner rotating member 4, the rotating member 5 and the outer rotating member 6 is synchronously released.
It should be noted that, the direction of the bump 707 with respect to the outer surface of the fourth pillar may be freely adjustable, and no matter where the bump 707 is located along the circumferential direction of the fourth pillar, the bump may make contact with the surface of the outer rotating member 6 away from the base 1, so as to achieve the limit.
Referring to fig. 4 to 7, in the present embodiment, it is preferable that: the control assembly 8 comprises a partition plate 801 which is in sliding fit with the top groove 103 up and down and moves synchronously with the first support column 701, and the partition plate 801 and the first support column 701 can be fixedly connected through bolts, can also be in rotating fit and can also be movably clamped, so long as the partition plate 801 and the first support column 701 can synchronously move up and down. A third spring 802 is fixedly installed between the partition plate 801 and the groove wall of the top groove 103, the third spring 802 is obliquely arranged, and the partition plate 801 can be defined based on the downward position and the upward position of the top groove 103 through the obliquely arranged third spring 802.
The side walls of the partition 801 are fixedly connected with a first pull rope 803, a second pull rope 804, a third pull rope 805 and a fourth pull rope 806 respectively, the first pull rope 803 is located at one side of the partition 801 close to the clamping block 2 and stretches into the base 1 to be fixedly connected with the bottom surface of the second support column 702, the second pull rope 804 is located at one side of the partition 801 far away from the clamping block 2 and stretches into the base 1 to be fixedly connected with the side wall of the third support column 704 close to the clamping block 2, the third pull rope 805 is located at the same side as the second pull rope 804 and stretches into the upper fourth support column 706 to be fixedly connected with the corresponding bump 707, and the fourth pull rope 806 is located at the same side as the first pull rope 803 and stretches into the lower fourth support column 706 to be fixedly connected with the corresponding bump 707.
When the partition plate 801 is located below the top groove 103, the third spring 802 is in an inclined downward state, and at this time, the first pull rope 803, the second pull rope 804, the third pull rope 805 and the fourth pull rope 806 are all lowered synchronously with the partition plate 801, so that the first pull rope, the second pull rope 804, the third pull rope 805 and the fourth pull rope 806 can all have margins and can be moved, at this time, the second spring 705 makes the second support column 702 rise through the margins of the first pull rope 803 and the second pull rope 804, the third support column 704 moves right relative to the base 1, and the third spring 802 makes the protrusion 707 extend relative to the corresponding fourth support column 706 through the margins of the third pull rope 805 and the fourth pull rope 806, so that the limiting of the inner rotating member 4, the rotating member 5 and the outer rotating member 6 can be realized. Conversely, if the spacer 801 is positioned above the top groove 103, the third spring 802 is inclined upward, and at this time, the first string 803, the second string 804, the third string 805, and the fourth string 806 are pulled upward by the spacer 801, the first string 803, the second string 804, the third string 805, and the fourth string 806 pull the corresponding second leg 702, third leg 704, and bump 707, respectively.
In the above structure, the guide wheel 807 is rotatably mounted in the base 1 to allow the first pull rope 803 and the fourth pull rope 806 to change direction, so that the first pull rope 803 and the fourth pull rope 806 can smoothly change direction to form a fixed connection with the partition 801, and the first pull rope 803 and the fourth pull rope 806 are in a relatively tensioned state. Meanwhile, the position where the fourth pull rope 806 extends from the fourth strut 706 may be disposed on a side of the fourth strut 706 away from the bump 707, so that the fourth pull rope 806 may smoothly drive the bump 707 to retract into the fourth strut 706 when ascending along with the partition 801.
When in use, the base 1 is arranged on a track (the dotted line square frame in fig. 2 is the track), and the inner rotating piece 4, the rotating piece 5 and the outer rotating piece 6 are respectively movably attached to the two side walls and the top surface of the track, so that the contact between the base 1 and the track is changed into rolling contact. When maintenance, repair or replacement of the inner rotating member 4, the rotating member 5 and the outer rotating member 6 is required in the later stage, the partition 801 is lifted up by the inclined third spring 802, the first pull rope 803, the second pull rope 804, the third pull rope 805 and the fourth pull rope 806 are pulled, the first support 701 is lifted up, the second support 702 is lowered down, the third support 704 is moved left relative to the base 1, and the bump 707 is correspondingly retracted into the fourth support 706, so that the limitation of the inner rotating member 4, the rotating member 5 and the outer rotating member 6 can be synchronously released.
In summary, through the cooperation of the structures such as the step 101, the partition 801, the bump 707 and the chain monomer 3, the inner rotating member 4, the rotating member 5 and the outer rotating member 6 can be quickly positioned, and the moving partition 801 can synchronously release the limit of the inner rotating member 4, the rotating member 5 and the outer rotating member 6, so that the maintenance, the overhaul or the replacement of the inner rotating member 4, the rotating member 5 and the outer rotating member 6 can be facilitated, the working efficiency of the disassembly operation can be effectively improved, and the overall work load is greatly reduced. The setting of step 101 makes and rotates respectively misplaces between piece 4, the rotation piece 5 and the outer rotation piece 6 in, can make things convenient for in rotating the piece 4 to follow taking out in the base 1, and step 101 cooperation chain monomer 3 can be favorable to the location of interior rotation piece 4 for the dismouting of interior rotation piece 4 can not cause the interference with chain monomer 3, can further improve work efficiency, and holistic practicality is higher.
Embodiment two: referring to fig. 1 to 10, in order to facilitate the installation of the inner rotary member 4, the rotary member 5, and the outer rotary member 6, the first support post 701, the second support post 702, the third support post 704, and the bump 707 are modified on the basis of the first embodiment: at this time, the sidewalls of the first pillar 701, the second pillar 702, the third pillar 704, and the bump 707 are each provided with a slope 708, and the first pillar 701 is elastically connected to the spacer 801 by the fourth spring 709.
It should be noted that, the distance that the first support post 701 can extend relative to the partition 801 is fixed, and the bottom surface of the first support post 701 is at most just contacted with the top surface of the chain monomer 3, or not contacted, or it is also possible that in fig. 8, the first support post 701 is at the maximum descending position relative to the partition 801, at this time, when the partition 801 ascends, the first support post 701 is still driven to ascend synchronously, but when the first support post 701 is stressed by the inclined surface 708, the first support post 701 can also automatically contract into the partition 801.
By the arrangement of the inclined surface 708, when the inner rotating member 4, the rotating member 5 and the outer rotating member 6 are installed, the first support column 701 can be contracted inwards to the partition plate 801, the second support column 702 descends, the third support column 704 moves leftwards relative to the base 1, the convex block 707 contracts inwards to the fourth support column 706 as long as the inner rotating member 4, the rotating member 5 and the outer rotating member 6 are correspondingly contacted with the inclined surface 708, and therefore the inner rotating member 4, the rotating member 5 and the outer rotating member 6 can be assembled quickly without moving the partition plate 801 for a plurality of times. The following first pillar 701, second pillar 702, third pillar 704 and bump 707 may be restored under the action of the first spring 703 and the second spring 705, respectively, to automatically realize the limitation of the inner rotary member 4, the rotary member 5 and the outer rotary member 6.
As seen in fig. 8, the inclined surfaces 708 of the first and second struts 701 and 702 and the inclined surfaces 708 of the upper and lower bumps 707 are in a splayed state as a whole, whereas the inclined surface 708 of the third strut 704 is in a left-side high-right low state when it is above and in a left-side low-right high state when it is below, so that the intermediate rotary member 5 can drive the third strut 704 to move left with respect to the base 1 when it contacts the inclined surface 708.
Referring to fig. 9 and 10, in the present embodiment, it is preferable that: the magnetic blocks 9 can be fixedly embedded between the first support 701 and the bottom of the partition plate 801, between the second support 702 and the third support 704 and the corresponding inner wall of the base 1, and the magnetic poles of the magnetic blocks 9 on the first support 701 and the partition plate 801, the magnetic poles of the magnetic blocks 9 on the second support 702 and the base 1, and the magnetic poles of the magnetic blocks 9 on the third support 704 and the base 1 are all of opposite design, and the directions of the first support 701, the second support 702 and the third support 704 are mutually attracted by magnetism, so that the inclined planes 708 can face the U-shaped opening 102 direction of the base 1, and the inclined planes 708 of the third support 704 can face the upper side or the lower side of the base 1, thereby facilitating the pushing of the inner rotating member 4 into the step 101 and the pushing of the rotating member 5 into the opening 102.
It should be noted that the magnetic blocks 9 may further serve to position the first support post 701, the second support post 702, and the third support post 704 in directions such that the inclined surfaces 708 may be oriented correspondingly to facilitate the placement of the inner rotary member 4 and the rotary member 5. In a specific application, the first spring 703 and the fourth spring 709 also have the function of positioning the third pillar 704, the second pillar 702 and the first pillar 701, even if the first pillar 701, the second pillar 702 and the third pillar 704 are self-rotated, the first spring 703 and the fourth spring 709 can automatically reset, and the magnet 9 can be matched in consideration of the service life of the springs.
Meanwhile, since the outer rotating member 6 is fixed by moving along the outer surface of the fourth support 706, the direction of the bump 707 with respect to the fourth support 706 is not limited, and the corresponding limitation can be automatically accomplished by moving the outer rotating member 6 along the outer surface of the fourth support 706.
When in use, the inner rotating member 4, the rotating member 5 and the outer rotating member 6 can be quickly positioned and quickly disassembled by the structures of the step 101, the partition 801, the bump 707 and the like, and the working process and the effect of the parts are the same as those of the first embodiment, and the repeated description is omitted. The difference is that: when the inner rotating member 4, the rotating member 5 and the outer rotating member 6 are installed, the inner rotating member 4 is pushed into the base 1, so that the inner rotating member 4 contacts with the inclined surfaces 708 of the first support post 701 and the second support post 702, the first support post 701 and the second support post 702 can be driven to be relatively far away from each other and relatively close to each other, and the limit of the upper rotating member 4 and the lower rotating member 4 can be automatically realized by matching the steps 101 and the chain monomers 3; when the middle rotating piece 5 is pushed into the opening 102, the third support column 704 can reciprocate relative to the base 1 through the inclined surface 708, so that the relative positioning is automatically realized; moving the outer rotating member 6 along the outer surface of the fourth leg 706 may then cause the protrusion 707 to retract and then extend relative to the fourth leg, such that the outer rotating member 6 is also automatically positioned.
In the first embodiment, the limit positions of the inner rotary member 4, the rotary member 5 and the outer rotary member 6 can be synchronized for easy disassembly, but the partition 801 must be in an upward state at the time of installation, and then the corresponding locking inner rotary member 4, the rotary member 5 and the outer rotary member 6 are moved downward, which still requires a multi-step operation and requires attention to the state of the partition 801, and there is a certain limitation in use.
Compared with the first embodiment, by the cooperation of the structures such as the inclined surface 708, the bump 707, the partition 801 and the step 101, the quick installation of the inner rotary member 4, the rotary member 5 and the outer rotary member 6 can be realized regardless of the up/down state of the partition 801, the partition 801 does not need to be moved many times without being affected by the position of the partition 801, and the overall work efficiency can be further improved and the work load can be reduced. The whole scheme combines together with the setting of first pillar, second pillar, third pillar and bump 707, easy operation and can not take place occupation space's change, and the cooperation of step 101 and chain monomer 3 is also convenient for the settling of interior rotation piece 4, and the suitability is stronger.
