Description

Technical Field

[0001] This utility model relates to the field of transmission devices, and in particular to an extendable and splicable roller rack transmission structure. Background Technology

[0002] The roller rack and pinion drive structure is a mechanical transmission method that combines the advantages of rollers and racks. It is used to convert linear motion into rotary motion and is commonly used in conveying systems. The drive device rotates the rollers, and the teeth on the rollers mesh with the teeth on the rack, thus converting rotary motion into linear motion. Conversely, if a linear force is applied to the rack, the rollers will also rotate, thus achieving the conversion between linear and rotary motion. In existing roller rack and pinion drive structures, the conveying length is extended by splicing the length of the guide rail rack. However, existing roller rack and pinion drive structures lack quick splicing of gear shafts, and the transmission shaft between gear shafts is fixedly connected to another gear shaft, making length adjustment difficult. When the existing gear shaft spacing does not meet the actual needs, the entire gear shaft section needs to be replaced, which is cumbersome and limits its use.

[0003] To address the aforementioned issues, a retractable and modular roller rack transmission structure has been developed. Utility Model Content

[0004] To overcome the shortcomings of existing roller rack and pinion transmission structures, such as the lack of quick splicing of gear shafts, the fixed connection between the transmission shafts of the gear shafts and the length being difficult to adjust, and the need to replace the entire gear shaft section when the existing gear shaft spacing does not meet the actual requirements, which is cumbersome and has limited use, this utility model provides an extendable and splicable roller rack and pinion transmission structure.

[0005] The technical solution of this utility model is: an extendable and splicable roller rack transmission structure, including a first mounting box, of which there are two. A second mounting box is connected to the upper side of each of the first and second mounting boxes. A mounting plate is connected to the upper side of each of the second mounting boxes, and a mounting plate is also connected to the lower side of each of the first and second mounting boxes. Side plates are connected to the front and rear sides of both the first and second mounting boxes. Guide rail racks are slidably connected to both the first and second mounting boxes, and these guide rail racks are slidably connected to adjacent side plates. Mounting shafts are connected between the left and right sides of adjacent first and second mounting boxes, and gear shafts are rotatably connected between adjacent left and right mounting shafts. These gear shafts mesh with adjacent guide rail racks. A first connecting block is connected to the inner side of each gear shaft. Second connecting blocks are connected to the left and right sides of each connecting cylinder, and these second connecting blocks engage with adjacent first connecting blocks. Locking elements are rotatably connected to each first connecting block, and these locking elements are threadedly connected to adjacent second connecting blocks.

[0006] To further explain, the side plate serves to limit the movement of the adjacent guide rail rack.

[0007] To further explain, the guide rail racks are all provided with threads for easy splicing.

[0008] To further clarify, the second connecting blocks are all detachable connection structures.

[0009] To further explain, each of the locking components is equipped with an assistive element.

[0010] To further explain, each of the locking components is equipped with a limit block.

[0011] By adopting the above technical solutions, the beneficial effects of this utility model are as follows: This invention extends the guide rack by using a threaded structure on the guide rack, thereby increasing its linear length. At the same time, it mounts a rotating connecting gear shaft, which is engaged by a first connecting block and a second connecting block and locked by a locking device. This allows for the rapid splicing of multiple gear shafts. Alternatively, a connecting cylinder of appropriate length can be replaced according to actual conveying needs, thereby flexibly adjusting the spacing between gear shafts to meet actual conveying requirements.

Detailed Implementation

[0017] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] An extendable and modular roller rack transmission structure, such as Figures 1-4 As shown, the system includes two first mounting boxes 1. Each first mounting box 1 has a second mounting box 2 connected to its upper side. Each second mounting box 2 has a mounting plate 3 connected to its upper side and a mounting plate 3 connected to its lower side. Side plates 4 are connected to the front and rear sides of both the first and second mounting boxes 1 and 2. The side plates 4 limit the movement of adjacent guide rail racks 5. Guide rail racks 5 are slidably connected to both the first and second mounting boxes 1 and 2. Each guide rail rack 5 has threads for easy assembly. The guide rail racks 5 are slidably connected to adjacent side plates 4. The first mounting boxes 1 are vertically adjacent. Mounting shafts 6 are connected between the left and right sides of the second mounting housing 2. Gear shafts 7 are rotatably connected between adjacent mounting shafts 6. Gear shafts 7 mesh with adjacent guide rail racks 5. First connecting blocks 9 are connected to the inner side of gear shafts 7. Second connecting blocks 10 are connected to the left and right sides of the connecting cylinder 8. The second connecting blocks 10 are all detachable connection structures. The second connecting blocks 10 are all snapped into the adjacent first connecting blocks 9. Locking parts 11 are rotatably connected to the first connecting blocks 9. Each locking part 11 is provided with an assisting part and a limit block. The locking parts 11 are all threadedly connected to the adjacent second connecting blocks 10.

[0019] It should be noted that the roller rack and pinion drive structure is a mechanical transmission method that combines the advantages of rollers and racks. It is used to convert between linear and rotary motion and is commonly applied in conveying systems. The drive unit rotates the rollers, and the teeth on the rollers mesh with the teeth on the rack, thus converting rotary motion into linear motion. Conversely, if a linear force is applied to the rack, the rollers will also rotate, thus achieving the conversion between linear and rotary motion. In existing roller rack and pinion drive structures, the conveying length is extended by splicing the length of the guide rail rack 5 to meet actual conveying requirements. The guide rail rack 5 can be extended using the threaded structure on it, thereby extending the linear length. However, existing roller rack and pinion drive structures lack gears. The rapid splicing of shaft 7, and the fixed connection between the transmission shafts of gear shaft 7 and another gear shaft 7, makes the length difficult to adjust. When the existing gear shaft 7 group spacing does not meet the actual needs, the entire gear shaft 7 part needs to be replaced, which is cumbersome and has limited use. When a single roller rack and pinion transmission structure cannot meet the actual needs, multiple gear shafts 7 need to be spliced ​​to operate simultaneously. A connecting cylinder 8 of appropriate length can be selected, and second connecting blocks 10 can be connected to its left and right sides. Then, the second connecting blocks 10 are snapped with the corresponding first connecting blocks 9. Then, the locking parts 11 are used to lock the first connecting blocks 9 and the second connecting blocks 10, thereby satisfying the rapid splicing of multiple gear shafts 7, and at the same time, the length of the connecting cylinder 8 can be flexibly adjusted to meet the actual conveying needs.

[0020] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
