Description

Technical Field

[0001] This utility model belongs to the field of chains, and particularly relates to a chain belt with a quick disassembly and installation structure. Background Technology

[0002] Chains are generally metal links or rings, primarily used for mechanical transmission and traction. They are chain-like objects used to obstruct traffic routes and chains used for mechanical transmission. Within the same product category, chains are classified according to their basic structure—that is, based on the shape of the components, the parts and locations that mesh with the chain, and the dimensional proportions between the parts. There are many types of chains, but their basic structures are only a few, with others being variations of these. From the chain structures mentioned above, we can see that most chains are composed of chain plates, chain pins, and bushings. Other types of chains simply modify the chain plates according to different needs; some add scrapers, some add guide bearings, and some add rollers, etc. These modifications are made for different applications. Currently, the disassembly and assembly of chains are very inconvenient and overly cumbersome.

[0003] For example, a Chinese utility model patent discloses a detachable chain [application number: CN202422109167.3]. This utility model patent includes an outer chain mechanism, a connecting mechanism, and an inner chain mechanism. The connecting mechanism has a fixing mechanism inside, which includes a locking block and a lower cavity. The locking block is located inside the lower part of the connecting mechanism, and the lower cavity is located above the bottom of the outer chain mechanism. The surface of the connecting mechanism is in contact with the outer chain mechanism. With this detachable chain, by setting the fixing mechanism, the screw inserted into the threaded hole is rotated to move down into the threaded groove at the top of the rotating shaft inside the rotating hole, until the bottom of the screw is in contact with the bottom of the threaded groove. Continuing to rotate the screw drives the rotating shaft to rotate, and the rotating shaft causes the locking block to move out of the upper cavity and slide along the groove into the lower cavity on the side of the bottom groove, thus completing the chain installation. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a chain belt with a quick-disassembly and installation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A chain belt with a quick-release and installation structure includes a chain belt with a plurality of outer chain sections and inner chain sections arranged sequentially. The outer chain sections and inner chain sections are connected by a connecting shaft. The two ends of the chain belt are respectively the outer chain section and the inner chain section. An assembly shaft is provided between one pair of outer chain sections at one end of the chain belt. A loading and unloading block is slidably provided on the assembly shaft. A shaft groove is provided in the inner chain section at the other end of the chain belt. The groove opening is open on the side near the end of the chain belt and is interconnected front and back. The assembly shaft can move into the shaft groove. A snap-fit ​​groove is connected in the middle of the shaft groove. The loading and unloading block can move into the snap-fit ​​groove and restrict the assembly shaft at the end of the shaft groove.

[0006] In the aforementioned chain belt with a quick-release and installation structure, a drive structure is connected between the loading / unloading block and the assembly shaft, and the drive structure can drive the loading / unloading block to move along the assembly shaft.

[0007] In the aforementioned chain belt with a quick-release and installation structure, the driving structure includes a driving sleeve shaft that is rotatably connected to the loading and unloading block. The driving sleeve shaft extends out of the loading and unloading block and is sleeved on the assembly shaft and screwed to the assembly shaft.

[0008] In the aforementioned chain belt with a quick-release and installation structure, an anti-detachment ring is provided at the connection between the drive sleeve shaft and the loading / unloading block. The anti-detachment ring is provided with several anti-rotation grooves. An anti-rotation rod is inserted into the loading / unloading block, and the anti-rotation rod can extend into any one of the anti-rotation grooves.

[0009] In the aforementioned chain belt with a quick-release and installation structure, the anti-rotation rod is screwed to the loading and unloading block.

[0010] In the aforementioned chain belt with a quick-release and installation structure, when the assembly shaft moves to the end of the shaft groove, there is a gap between the assembly shaft and the snap-fit ​​groove, and the loading / unloading block has a snap-fit ​​area that matches the shape of the gap.

[0011] In the aforementioned chain belt with a quick-release and installation structure, an anti-rotation block is slidably provided at one end of the loading / unloading block near the inner chain. The cross-sectional shape of the anti-rotation block is the same as that of the loading / unloading block. Before the loading / unloading block moves into the locking groove, the anti-rotation block first slides into the locking groove.

[0012] In the aforementioned chain belt with a quick-disassembly and installation structure, the anti-rotation block is slidably connected to the loading and unloading block via a sliding shaft, the sliding shaft is fitted with a limiting plate, and the loading and unloading block is fitted with a limiting groove that is slidably connected to the limiting plate.

[0013] In the aforementioned chain belt with a quick-release and installation structure, the assembly shaft is fixed to the outer chain section by bolts.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. During assembly, insert one end of the inner chain of one chain belt into the assembly shaft of the outer chain of another chain belt, so that the assembly shaft extends into the shaft groove of the inner chain and moves to the end of the shaft groove through the snap-fit ​​groove. Then, move the loading and unloading block on the assembly shaft into the snap-fit ​​groove so that the loading and unloading block and the inner chain form a snap-fit ​​and restrict the assembly shaft to the end of the shaft groove, making installation and disassembly convenient.

[0015] 2. Rotate the drive sleeve shaft to move the loading and unloading block into the locking groove through a screw connection. Using a screw connection instead of a sliding connection increases the stability after installation and prevents the loading and unloading block from moving out of the locking groove.

[0016] 3. After the loading and unloading block is moved into the locking groove, the anti-rotation rod is inserted into the anti-rotation groove to prevent the drive sleeve shaft from rotating, further increasing the stability after installation. Attached Figure Description

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] This embodiment provides a chain belt with a quick-disassembly and installation structure, combined with... Figure 1-4As shown, the chain includes a chain belt with several outer chain sections 10 and inner chain sections 11 arranged sequentially. The outer chain sections 10 and inner chain sections 11 are connected by a connecting shaft. The two ends of the chain belt are the outer chain section 10 and the inner chain section 11, respectively. An assembly shaft 12 is provided between one pair of outer chain sections 10 at one end of the chain belt. A loading and unloading block 13 is slidably provided on the assembly shaft 12. A shaft groove 14 is provided in the inner chain section 11 at the other end of the chain belt. The groove opening of the shaft groove 14 is open on the side near the end of the chain belt and is interconnected. The assembly shaft 12 can move into the shaft groove 14. A snap-fit ​​groove 15 is connected in the middle of the shaft groove 14. The loading and unloading block 13 can move into the snap-fit ​​groove 15 and restrict the assembly shaft 12 at the end of the shaft groove 14.

[0021] In this embodiment, during assembly, one end of the inner chain portion 11 of one chain belt is inserted into the assembly shaft 12 of the outer chain portion 10 of another chain belt, so that the assembly shaft 12 extends into the shaft groove 14 of the inner chain portion 11 and moves to the end of the shaft groove 14 via the snap-fit ​​groove 15. Then, the mounting and dismounting block 13 on the assembly shaft 12 is moved into the snap-fit ​​groove 15 so that the mounting and dismounting block 13 and the inner chain portion 11 form a snap-fit ​​and restrict the assembly shaft 12 to the end of the shaft groove 14, making installation and disassembly convenient.

[0022] The loading / unloading block 13 is connected to the assembly shaft 12 by a drive structure, which can drive the loading / unloading block 13 to move along the assembly shaft 12.

[0023] In this embodiment, the loading / unloading block 13 is driven to move into the snap-fit ​​slot 15 by a drive structure.

[0024] The drive structure includes a drive sleeve 16 rotatably connected to the loading and unloading block 13. The drive sleeve 16 extends out of the loading and unloading block 13 and is sleeved on the assembly shaft 12 and screwed to the assembly shaft 12.

[0025] In this embodiment, the rotating drive sleeve shaft 16 moves the loading and unloading block 13 into the locking groove 15 by means of screw connection. The screw connection, rather than the sliding connection, increases the stability after installation and prevents the loading and unloading block 13 from moving out of the locking groove 15.

[0026] The connection between the drive sleeve shaft 16 and the loading / unloading block 13 is provided with an anti-detachment ring 17. The anti-detachment ring 17 is provided with a plurality of anti-rotation grooves 19. The loading / unloading block 13 is inserted with an anti-rotation rod 18, which can extend into any one of the anti-rotation grooves 19.

[0027] In this embodiment, after the loading and unloading block 13 is moved into the snap-fit ​​groove 15, the anti-rotation rod 18 is inserted into the anti-rotation groove 19 to prevent the drive sleeve shaft 16 from rotating, thereby further increasing the stability after installation.

[0028] The anti-rotation rod 18 is screwed to the loading and unloading block 13.

[0029] In this embodiment, post-installation stability is further enhanced.

[0030] When the assembly shaft 12 moves to the end of the shaft groove 14, there is a gap between the assembly shaft 12 and the snap-fit ​​groove 15, and the loading and unloading block 13 has a snap-fit ​​area 20 that matches the shape of the gap.

[0031] In this embodiment, the gap between the assembly shaft 12 and the shaft groove 14 and the snap-fit ​​groove 15 is filled to prevent the assembly shaft 12 from shaking in the shaft groove 14 and improve the stability of the chain belt.

[0032] An anti-rotation block 21 is slidably provided at one end of the loading / unloading block 13 near the inner chain part 11. The cross-sectional shape of the anti-rotation block 21 is the same as that of the loading / unloading block 13. When the loading / unloading block 13 has not moved into the locking groove 15, the anti-rotation block 21 first slides into the locking groove 15.

[0033] In this embodiment, before the drive sleeve shaft 16 is rotated, the anti-rotation block 21 is slid to move the anti-rotation block 21 into the locking groove 15, so that the loading and unloading block 13 enters the locking groove 15 in advance. When the drive sleeve shaft 16 is rotated, the loading and unloading block 13 can be prevented from rotating and can slide smoothly into the locking groove 15.

[0034] The anti-rotation block 21 is slidably connected to the loading and unloading block 13 via a sliding shaft 22. The sliding shaft 22 is fitted with a limiting piece 23, and the loading and unloading block 13 is provided with a limiting groove 24 that is slidably connected to the limiting piece 23.

[0035] The assembly shaft 12 is fixed to the outer chain portion 10 by bolts. The specific embodiments described herein are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0036] Although this article frequently uses terms such as outer link 10, inner link 11, assembly shaft 12, loading and unloading block 13, shaft groove 14, snap-fit ​​groove 15, drive sleeve shaft 16, anti-disengagement ring 17, anti-rotation rod 18, anti-rotation groove 19, snap-fit ​​area 20, anti-rotation block 21, sliding shaft 22, limiting piece 23, and limiting groove 24, these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
