A flute with a buffer structure

Abstract

This utility model relates to the field of flow slide technology and discloses a flow slide with a buffer structure. The flow slide with a buffer structure includes a mounting shell, a connecting shaft inside the mounting shell, a roller rotatably connected to the arc surface of the connecting shaft, a buffer mechanism inside the mounting shell, a promoting mechanism inside the mounting shell, a sealing block detachably connected to the upper surface of the mounting shell by bolts, and a mounting block fixedly installed on the inner wall of the mounting shell. In this flow slide with a buffer structure, a rubber sleeve is fixedly installed on the surface of the roller. When the roller is impacted, the rubber sleeve deforms to buffer a certain amount of impact force. Simultaneously, the slider moves along the straight rod, and the return spring deforms to buffer the impact. As the sleeve moves along the straight rod, a limiting ring on the sleeve, in conjunction with a rubber pad, limits the movement distance of the slider, ensuring the deformation of the return spring, thereby ensuring stable operation and relative stability of the roller.

Description

Technical Field

[0001] This utility model relates to the field of flow strip technology, specifically a flow strip with a buffer structure. Background Technology

[0002] Gravity flow strips are composed of long grooved extruded aluminum profiles, plastic profiles, or sheet metal frames, as well as simple rollers arranged and installed between the frame grooves. By assembling many gravity flow strips together, a load-bearing surface for conveying goods or shelving equipment can be formed. They are easy to miniaturize, have a simple structure, and excellent sliding properties, making them particularly suitable for manufacturing light-duty gravity conveyors or gravity shelving.

[0003] According to a public notice regarding a type of easy-to-assemble smooth strip (publication number: CN217321881U), the aforementioned application allows for quick disassembly or assembly via pressing. Additionally, the upper sides of the supporting keel feature rectangular rolled edges, enhancing overall torsional resistance. The sliding wheels are designed with a hollow structure to reduce weight.

[0004] However, in actual use, the rollers on the flow bar transport items and are subjected to impacts when items are placed on them. This causes the rollers to bear excessive loads, which will lead to wear and deformation of the structure. In view of this, we propose a flow bar with a buffer structure. Utility Model Content

[0005] The purpose of this invention is to provide a flow strip with a buffer structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flow strip with a buffer structure, comprising a mounting shell, a connecting shaft disposed inside the mounting shell, a roller rotatably connected to the arc surface of the connecting shaft, a buffer mechanism disposed inside the mounting shell, and a promoting mechanism disposed inside the mounting shell, the buffer mechanism comprising:

[0007] A sealing block is detachably connected to the upper surface of the mounting housing by bolts. The mounting block is fixedly installed on the inner wall of the mounting housing. A straight rod is fixedly installed on the inner wall of the mounting housing. A return spring is fixedly installed on the inner wall of the mounting housing.

[0008] A sleeve is fixedly connected to the end of the return spring away from the mounting shell. A rubber pad is fixedly installed on the surface of the sleeve, and a slider is sleeved on the arc surface of the straight rod.

[0009] Preferably, the promoting mechanism includes an auxiliary shaft, which is fixedly mounted on the side wall of the slider, and an auxiliary wheel is rotatably connected to the arc surface of the auxiliary shaft.

[0010] Preferably, the auxiliary wheel and the roller are arranged in an alternating manner, which allows the auxiliary wheel and the roller to better withstand greater loads and protect the roller.

[0011] Preferably, the surface of the mounting block has a circular hole, and a return spring and a straight rod are fitted inside the circular hole, so that the return spring can deform inside the mounting block.

[0012] Preferably, a limiting ring is fixedly installed on the upper surface of the sleeve. The diameter of the limiting ring is larger than the diameter of the circular hole, so that the sleeve is restricted from moving a certain distance by the limiting ring, thus preventing the return spring from being excessively deformed.

[0013] Preferably, the side wall of the mounting shell is provided with a groove, the shape of which is adapted to the shape of the mounting block, and the slider is adapted to the shape of the mounting block, so that the slider can move inside the groove.

[0014] Preferably, the number of grooves is set to several, and the several grooves are formed in a linear array on the side wall of the mounting shell. The arrangement of multiple grooves facilitates the installation of multiple rollers and auxiliary wheels.

[0015] Compared with the prior art, this utility model provides a flow strip with a buffer structure, which has the following beneficial effects:

[0016] 1. This flow bar with a buffer structure has a buffer mechanism. A rubber sleeve is fixedly installed on the surface of the roller. When the roller is impacted, the rubber sleeve deforms to buffer a certain impact force. At the same time, the slider moves along the straight rod, and the return spring deforms to buffer the impact. As the sleeve moves along the straight rod, the limiting ring on the sleeve, together with the rubber pad, limits the movement distance of the slider, ensuring the deformation of the return spring, thereby making the roller run stably and relatively stable.

[0017] 2. The flow bar with a buffer structure is equipped with a promoting mechanism. The auxiliary shaft and auxiliary wheel are staggered with the roller. The staggered arrangement of the auxiliary wheel and roller can better withstand a larger load and protect the roller. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a flow bar with a buffer structure, including a mounting shell 1, a connecting shaft 2 is provided inside the mounting shell 1, a roller 5 is rotatably connected to the arc surface of the connecting shaft 2, a buffer mechanism 3 is provided inside the mounting shell 1, and a promoting mechanism 4 is provided inside the mounting shell 1. The buffer mechanism 3 includes a sealing block 301, a mounting block 302, a straight rod 303, a return spring 304, a sleeve 305, a rubber pad 306, and a slider 307.

[0024] In one embodiment of this utility model, the sealing block 301 is detachably connected to the upper surface of the mounting shell 1 by bolts. The mounting block 302 is fixedly installed on the inner wall of the mounting shell 1. The straight rod 303 is fixedly installed on the inner wall of the mounting shell 1. The return spring 304 is fixedly installed on the inner wall of the mounting shell 1. The sleeve 305 is fixedly connected to the end of the return spring 304 away from the mounting shell 1. The surface of the sleeve 305 is fixedly installed with a rubber pad 306. The arc surface of the straight rod 303 is fitted with a slider 307.

[0025] In addition, the promoting mechanism 4 includes an auxiliary shaft 401, which is fixedly installed on the side wall of the slider 307. The arc surface of the auxiliary shaft 401 is rotatably connected to an auxiliary wheel 402. The auxiliary wheel 402 and the roller 5 are staggered, so that the staggered arrangement of the auxiliary wheel 402 and the roller 5 can better bear the larger load and protect the roller 5.

[0026] In this embodiment of the invention, a circular hole is formed on the surface of the mounting block 302, and a return spring 304 and a straight rod 303 are fitted inside the circular hole, allowing the return spring 304 to deform inside the mounting block 302. A limiting ring is fixedly installed on the upper surface of the sleeve 305, and the diameter of the limiting ring is larger than the diameter of the circular hole, so that the sleeve 305 is restricted from moving a certain distance by the limiting ring, preventing the return spring 304 from deforming excessively. A groove is formed on the side wall of the mounting shell 1, and the shape of the groove is adapted to the shape of the mounting block 302. The slider 307 is adapted to the shape of the mounting block 302, so that the slider 307 can move inside the groove. Several grooves are provided, and several grooves are formed in a linear array on the side wall of the mounting shell 1. The multiple grooves facilitate the installation of multiple rollers 5 and auxiliary wheels 402. A connecting shaft 2 is fixedly installed on the side wall of the slider 307.

[0027] In this invention, a rubber sleeve is fixedly installed on the surface of the roller 5 during use. When the roller 5 is impacted, the rubber sleeve deforms to buffer a certain impact force. At the same time, the slider 307 moves along the straight rod 303, and the return spring 304 deforms to buffer the impact. As the sleeve 305 moves along the straight rod 303, the limiting ring on the sleeve 305, together with the rubber pad 306, limits the movement distance of the slider 307, ensuring the deformation of the return spring 304, thereby making the roller 5 run stably and relatively stable.

[0028] Furthermore, the auxiliary shaft 401 is staggered with the auxiliary wheel 402 and the roller 5, and the staggered arrangement of the auxiliary wheel 402 and the roller 5 can better withstand the larger load and protect the roller 5.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
