Description

Technical Field

[0001] This utility model relates to the field of double-speed chain technology, specifically a double-speed chain conveyor track mechanism. Background Technology

[0002] The double-speed chain conveyor works by using the speed-increasing function of the chain to rapidly move the tooling plates supporting the goods, stopping them at corresponding operating positions via stoppers; or by using corresponding commands to complete machine room actions, such as movement, rotation, and line transfer. It uses specially treated extruded aluminum alloy profiles as guide rails, providing excellent stability and durability during conveying, making it suitable for high-volume continuous production and widely used in production lines of various electronics, electrical appliances, and electromechanical industries.

[0003] In the prior art, a search revealed Chinese patent CN215100153U, which discloses a double-speed chain conveyor track with a detachable load-bearing guide rail. This track comprises a main body and a detachable load-bearing guide rail. The main body consists of a lower, enclosed hollow structure and an upper, open hollow structure. The detachable load-bearing guide rail is composed of a horizontal base and two vertically connected left and right beams, which are detachably connected to the base plate on the upper part of the main body. This design utilizes replaceable, wear-resistant guide rails, allowing for individual replacement when the rails wear out, thus reducing operating costs and avoiding the need to replace the entire track.

[0004] However, the above-mentioned solutions still have the following drawbacks: Since conveyor tracks are typically long, a large number of connecting screws are needed to fix the detachable load-bearing guide rails to the track body. This not only increases the workload of installation and maintenance but also consumes a significant amount of time for disassembling bolts when replacing guide rails, severely impacting work efficiency. Furthermore, frequent bolt disassembly and assembly operations can damage the threaded holes, further affecting the track's service life and stability. Therefore, this utility model proposes a double-speed chain conveyor track mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a track mechanism for a double-speed chain conveyor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a double-speed chain conveyor track mechanism, comprising: a track body, a limiting rail fixedly connected to the bottom inner side of the track body, the bottom of the limiting rail being slidably connected to the load-bearing section guide rail via a slide rail, the limiting rail being fixedly connected to the load-bearing section guide rail, and several slots being provided on both sides of the load-bearing section guide rail, with a snap-fit ​​component provided on one side of each slot.

[0007] The limit rail and slide rail are provided with threaded holes on both sides of the top. The threaded holes are fitted with internal hexagonal bolts. The outer ring of the nut on the top of the internal hexagonal bolt is provided with a limit hole. A limit component is provided on one side of the limit hole.

[0008] Preferably, the snap-fit ​​assembly includes an L-shaped plate fixedly installed on the top side of the track body, with a push-pull rod slidably fitted on one end of the L-shaped plate, and a fixed slide block fixedly connected to the upper surface of the other end of the L-shaped plate.

[0009] Preferably, the upper side of the fixed slide block is slidably connected to one end of the movable block via a guide block, and a snap-fit ​​plate is fixedly connected to the lower side of the other end of the movable block. The movable block is slidably sleeved on the side of the track body, and the snap-fit ​​plate is slidably connected to the snap-fit ​​groove.

[0010] Preferably, one end of the push-pull rod is rotatably connected to one end of the connecting plate via a small pin, and the other end of the connecting plate is rotatably connected to the moving block via a large pin. A connecting frame is fixedly connected to one end of the push-pull rod.

[0011] Preferably, the push-pull rod is fixedly connected to the L-shaped plate on the side away from the connecting plate by a first spring, and the top of the connecting frame is fixedly connected to the connecting rod.

[0012] Preferably, the limiting component includes a rod that is slidably sleeved on the bottom side of the track body, one end of the rod being slidably inserted into a limiting hole, and the other end of the rod being fixedly connected to a limiting pull plate.

[0013] Preferably, the limiting holes are arranged in a circumferential array around the outer ring of the top nut of the internal hexagonal bolt, and a second spring is fixedly connected between one side of the limiting pull plate and the bottom side of the track body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Compared with existing technologies, this track structure reduces the use of bolts through the combined use of limiting rails, slide rails, snap-fit ​​components, and limiting components. The snap-fit ​​components, working in conjunction with the slots, initially limit and fix the load-bearing guide rail, and then further secure it with hexagonal socket head cap screws. The limiting components prevent bolt loosening, thus solving the problem of time-consuming bolt removal and installation during load-bearing guide rail replacement and improving the efficiency of load-bearing guide rail replacement.

[0016] 2. Compared with existing technologies, this track structure uses a pressing connecting rod to cause the push-pull rod to move the locking plate laterally, inserting the locking plate into the slot to achieve initial positioning and fixation of the load-bearing section guide rail. When further fixation is required, the hexagonal socket bolts are tightened, and the insert rod is inserted into the limiting hole to prevent the bolts from rotating, ensuring the firmness of the hexagonal socket bolts and avoiding unstable fixing of the load-bearing section guide rail due to loose bolts, thus ensuring the stability and reliability of the load-bearing section guide rail installation.

[0017] 3. Compared with existing technologies, when the load-bearing section guide rail needs to be removed or replaced, this track structure only requires pulling the limit plate in the opposite direction to release the limit of the insert rod on the internal hexagon bolt, and then pulling the connecting rod to release the limit of the snap plate and the slot, so that the load-bearing section guide rail can be easily pulled out. The operation is simple and convenient, which significantly improves the efficiency of maintenance and replacement work. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1 to 5This utility model provides a technical solution: a double-speed chain conveyor track mechanism, comprising: a track body 1, a limiting rail 2 fixedly connected to the bottom inner side of the track body 1, the limiting rail 2 limiting the slide rail 3, the bottom of the limiting rail 2 being slidably connected to the load-bearing section guide rail 4 via the slide rail 3, the bottom of the load-bearing section guide rail 4 being slidably connected to the track body 1, the limiting rail 2 being fixedly connected to the load-bearing section guide rail 4, several slots 5 being provided on both sides of the load-bearing section guide rail 4, a snap-fit ​​component being provided on one side of the slot 5, the load-bearing section guide rail 4 being initially limited by the snap-fit ​​component cooperating with the slot 5, threaded holes 6 being provided on both sides of the top of the limiting rail 2 and the slide rail 3, an internal hexagon bolt 7 being threaded into the internal thread of the threaded hole 6, a limiting hole 8 being provided on the outer ring surface of the nut at the top of the internal hexagon bolt 7, a limiting component being provided on one side of the limiting hole 8, the internal hexagon bolt 7 being limited by the limiting component and the limiting hole 8.

[0026] When it is necessary to fix the load-bearing section guide rail 4, first slide the load-bearing section guide rail 4 into the track body 1 through the sliding fit between the limiting rail 2 and the slide rail 3 until the load-bearing section guide rail 4 is completely slid into the track body 1. At this time, the threaded hole 6 on the limiting rail 2 and the slide rail 3 is coaxial. Then, the load-bearing section guide rail 4 is initially fixed by the snap-fit ​​component engaging the slot 5. Then, hexagon socket bolts 7 are screwed into the threaded hole 6 on the limiting rail 2 and the slide rail 3 to further fix the load-bearing section guide rail 4. After the load-bearing section guide rail 4 is fixed, the limiting component limits the limiting hole 8 to avoid The design eliminates the need for the hex bolt 7 to rotate, thus preventing it from loosening and ensuring the stability of the load-bearing guide rail 4. When the load-bearing guide rail 4 needs to be removed or replaced, simply release the limiting component from the limiting hole 8 to remove the hex bolt 7. Then, by releasing the locking component from the locking slot 5, the load-bearing guide rail 4 can be pulled out from the rail body 1 for replacement. This reduces the use of bolts. By replacing multiple sets of bolts with locking and limiting components, the problem of spending a lot of time removing bolts when replacing the load-bearing guide rail 4 is solved, improving the efficiency of the load-bearing guide rail 4 replacement.

[0027] Example 2: Based on Example 1, the snap-fit ​​assembly includes an L-shaped plate 9 fixedly installed on the top side of the track body 1. The L-shaped plates 9 are symmetrically arranged on both sides of the top of the track body 1 in a linear array. A push-pull rod 10 is slidably fitted onto one end of the L-shaped plate 9, limiting the push-pull rod 10. A fixed slide block 11 is fixedly connected to the upper surface of the other end of the L-shaped plate 9. The upper side of the fixed slide block 11 is slidably connected to one end of the moving block 12 through a guide block 13. The sliding between the fixed slide block 11 and the guide block 13 limits the moving block 12. A snap-fit ​​plate 14 is fixedly connected to the lower side of the other end of the moving block 12. The movable sleeve is located on the side of the track body 1. The snap-fit ​​plate 14 can move laterally. The snap-fit ​​plate 14 is slidably connected to the snap-fit ​​groove 5. One end of the push-pull rod 10 is rotatably connected to one end of the connecting plate 15 through a small pin. The other end of the connecting plate 15 is rotatably connected to the moving block 12 through a large pin. The connecting plate 15 is used for transmission between the push-pull rod 10 and the connecting plate 15. One end of the push-pull rod 10 is fixedly connected to the connecting frame 16. The side of the push-pull rod 10 away from the connecting plate 15 is fixedly connected to the L-shaped plate 9 through the first spring 17. The top of the connecting frame 16 is fixedly connected to the connecting rod 18. The linear array of connecting frames 16 is fixedly connected to each other through the connecting rod 18.

[0028] Before fixing the load-bearing guide rail 4, press the connecting rod 18 to move it along its own axis and towards the fixed slide 11. This, in turn, drives the push-pull rod 10 to move under the connection of the connecting frame 16. The push-pull rod 10 slides under the limit of the L-shaped plate 9, compressing the first spring 17 and simultaneously pushing one end of the connecting plate 15 through the small pin. The other end of the connecting plate 15 drives the moving block 12 through the large pin. The moving block 12 moves to the side of the track body 1 under the sliding cooperation of the guide block 13 and the fixed slide 11. The moving block 12 simultaneously drives the locking mechanism... When the connecting plate 14 moves, the load-bearing section guide rail 4 slides into the track body 1 through the sliding fit between the limiting rail 2 and the slide rail 3 until the load-bearing section guide rail 4 is completely slid into the track body 1. At this time, the threaded hole 6 opened on the limiting rail 2 and the slide rail 3 is coaxial. Then, the connecting rod 18 is released. Under the action of the reverse elastic force of the first spring 17, the push-pull rod 10 moves in the opposite direction. Thus, the push-pull rod 10 pulls the moving block 12 in the opposite direction through the connecting plate 15, so that the moving block 12 drives the locking plate 14 to move closer to the load-bearing section guide rail 4 until one side of the locking plate 14 is inserted into the slot 5, thereby initially limiting and fixing the load-bearing section guide rail 4.

[0029] Example 3: Based on Example 2, the limiting component includes a rod 19 slidably sleeved on the bottom side of the track body 1. One end of the rod 19 is slidably inserted into the limiting hole 8. The rod 19 limits the internal hexagon bolt 7 by being inserted into the limiting hole 8. The other end of the rod 19 is fixedly connected to a limiting pull plate 20. The limiting pull plate 20 facilitates the movement of the rod 19. The limiting holes 8 are arranged in a circumferential array around the outer ring surface of the top nut of the internal hexagon bolt 7, and several limiting holes 8 are provided to facilitate the insertion of the rod 19. A second spring 21 is fixedly connected between one side of the limiting pull plate 20 and the bottom side of the track body 1. The setting of the second spring 21 facilitates the reset of the rod 19. Two plastic chain covers are provided on both sides of the top of the track body 1. Several load-bearing double-speed chain rollers are provided on the inner wall of the load-bearing section guide rail 4.

[0030] After the load-bearing guide rail 4 is initially fixed, the limiting pull plate 20 is pulled away from the threaded hole 6, causing it to pull the second spring 21. Simultaneously, the insertion rod 19 moves synchronously. At this time, the internal hex bolt 7 is threaded into the threaded hole 6 between the limiting rail 2 and the slide rail 3, thus further fixing the load-bearing guide rail 4. After the load-bearing guide rail 4 is fixed, the limiting pull plate 20 is released. Under the reverse elastic force of the second spring 21, the insertion rod 19 is inserted into the limiting hole 8 on the outer ring surface of the nut at the top of the internal hex bolt 7. To prevent the hex bolt 7 from rotating and thus avoid loosening, further improving the reliability of the load-bearing guide rail 4, when the load-bearing guide rail 4 needs to be disassembled and replaced, simply pull the limiting pull plate 20 in the opposite direction to remove the internal hex bolt. Then, by pulling the connecting rod 18 in the opposite direction, the limiting of the locking plate 14 and the locking groove 5 can be released. Finally, push the load-bearing guide rail 4, and with the cooperation of the limiting rail 2 and the slide rail 3, completely push the load-bearing guide rail 4 out of the limiting rail 2, thereby allowing the load-bearing guide rail 4 to be removed from the track body 1.
