Description

Technical Field

[0001] The utility model relates to the technical field of flow bars, in particular to a flow bar that is convenient for separately replacing rollers. Background Technique

[0002] A flow bar is the abbreviation of an aluminum alloy slide rail. Because it is convenient and fast to install, and the items placed on it run smoothly, it is called a flow bar as the name implies.

[0003] In order to cooperate with material transmission in workshops, factories, etc., most of the existing flow bars are manufactured with a longer length, so the number of rollers also increases accordingly. This may result in the need to disassemble and replace the entire flow bar if one of the rollers is damaged, which is extremely costly. The force exerted by the rollers when carrying materials will all be transferred to the profile slideway. Prolonged use may cause the profile slideway to crack and be damaged. Moreover, in order to reduce costs in the market, there are plastic product flow bars, and the load-bearing capacity of their profile slideways is even weaker.

[0004] As disclosed in a flow bar that is convenient for separately replacing rollers in Chinese Patent CN211919819U, by pulling two pull plates on the profile slide wall, both pull plates drive the movable rods to move upward. At this time, the movable rods vertically move upward through the first sliders in the first chutes until the bottom ends of the movable rods are separated from the slots in the engaging rods. Then, the staff pulls the right end of the engaging rod, pulls out the engaging rod, removes the damaged roller for replacement. Similarly, insert the engaging rod until the limiting block fits against the profile slide wall, indicating that the slots on the engaging rod have reached the same vertical height as the movable rods. At this time, loosen the pull plates, and the restoring force generated by the elasticity of the first spring drives the movable rods to move downward until they are engaged with the slots to complete the installation.

[0005] However, for the structure for separately replacing rollers of the flow bar used in the above-mentioned comparative document, because it uses a plug-in structure, and there are gaps in the connection process of the plug-in structure, it will cause the rollers to shake during the process of conveying materials, resulting in unstable logistics transportation.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A smooth strip that facilitates the individual replacement of rollers, including a frame 1, with a disassembly and assembly structure installed on the top of the frame 1, a protective structure installed on the front and back of the frame 1, and a shock-absorbing structure installed on the bottom of the frame 1.

[0030] The disassembly and assembly structure includes a stability unit and a conveying unit. The stability unit is arranged on the top of the front and back of the conveying unit. The stability unit includes a mounting plate 101, positioning blocks 102 are installed in the middle of the left and right sides of the mounting plate 101, a fixing bolt 103 is installed in the middle of the top surface of the positioning block 102, abutting rods 104 are installed near the left and right ends of the middle of the bottom surface of the mounting plate 101, and pressing pieces 105 are installed at the bottom ends of the abutting rods 104. The conveying unit includes a bearing 106, a rotating shaft 107 is installed inside the bearing 106, and a roller 108 is installed in the middle of the outer surface of the rotating shaft 107.

[0031] The bearing 106 is installed inside the installation groove opened at the top of the frame 1. The outer surface of the positioning block 102 is connected to the inside of the positioning groove opened at the top of the frame 1. The fixing bolt 103 is threadedly connected to the inside of the threaded groove opened in the positioning groove at the top of the frame 1. The bottom surface of the pressing piece 105 abuts against the top of the outer surface of the bearing 106, and the left and right sides of the pressing piece 105 are slidably connected to the left and right sides of the inner wall of the installation groove opened at the top of the frame 1.

[0032] Through the setting of the disassembly and assembly structure, the positioning block 102, the mounting plate 101, the abutting rod 104, and the pressing piece 105 are installed and fixed by using the fixing bolt 103, so as to effectively fix the bearing 106 by using the pressing piece 105, thereby stably installing and positioning the roller 108 and ensuring the stable use effect of the roller 108.

[0033] By rotating the fixing bolt 103, the positioning block 102 and the mounting plate 101 can be installed inside the positioning groove at the top of the frame 1, so as to drive the abutting rod 104 and the pressing piece 105 to press the top of the outer surface of the bearing 106 by using the mounting plate 101, thereby effectively ensuring the stability of the bearing 106 during use. Similarly, the stable use effects of the rotating shaft 107 and the roller 108 can be effectively ensured. When one of the multiple rollers 108 installed inside the frame 1 is damaged during use, the fixing bolt 103 of its same group can be correspondingly disassembled, and thus the damaged bearing 106, rotating shaft 107, and roller 108 can be quickly disassembled and replaced.

[0034] Embodiment 2:

[0035] Based on the first embodiment, the protection structure includes a guide rail 201. In the middle of the top surface of the guide rail 201, a limiting strip 202 is installed. At the top of the limiting strip 202, a protection plate 203 is fixedly installed. At the top end of the protection plate 203, a cover plate 204 is fixedly installed. The guide rail 201 is fixedly installed in the middle of the front and back of the frame 1. The outer surface of the limiting strip 202 is slidably connected to the inner wall of the convex chute opened in the middle of the top surface of the guide rail 201.

[0036] The shock absorption structure includes a shock absorption box 301. At the bottom surface inside the shock absorption box 301, a damping rod 302 is installed. At one side near the front and back of the bottom surface inside the shock absorption box 301, a limiting block 304 is installed. At the top of the outer surface of the limiting block 304, a limiting groove 303 is connected. The inner wall of the shock absorption box 301 is slidably connected to the bottom surface of the outer surface of the frame 1. One end of the damping rod 302 away from the bottom surface inside the shock absorption box 301 is connected to the bottom surface of the frame 1. The top end of the limiting groove 303 is fixedly connected to the bottom surface of the frame 1.

[0037] Through the setting of the shock absorption structure, by using the sliding connection between the inner wall of the shock absorption box 301 and the bottom surface of the outer surface of the frame 1, and by using the installation of the limiting groove 303 and the limiting block 304, the sliding of the frame 1 inside the shock absorption box 301 is limited, and the damping rod 302 is squeezed during the sliding process. Thus, the damping rod 302 is used to absorb the shock, preventing damage to the fluent strip caused by impact during use.

[0038] During the use of the fluent strip, by using the sliding connection of the limiting strip 202 inside the convex slide opened at the top of the guide rail 201, the installation of the protection plate 203 and the cover plate 204 is realized. Thus, the protection plate 203 and the cover plate 204 can be used to prevent dust from entering the bearing 106 and the rotating shaft 107, preventing dust particles from entering the inside of the bearing 106 and affecting the service life of the bearing 106. And during the process of using the rotating shaft 107 and the roller 108 to convey heavy objects, due to the impact force generated by the heavy object on the roller 108, the bottom surface of the outer surface of the frame 1 slides with the top end inside the shock absorption box 301. At the same time, during the sliding process, by using the sliding connection of the limiting groove 303 and the limiting block 304, the movement process is limited, and the damping rod 302 is squeezed when receiving the impact force. Thus, the damping rod 302 is used to absorb the impact force, ensuring the overall service life of the fluent strip.
