Description

Technical Field

[0001] This utility model relates to the field of mechanical chain technology, specifically a mechanical chain tension adjustment device. Background Technology

[0002] Chains are a common type of mechanical component, and different chains have different lengths. When a chain is too long, it cannot maintain a taut state, which will prevent the chain from transmitting power. The problem that this device addresses is how to keep chains of different lengths always taut.

[0003] A search revealed that patent application CN221503895U discloses an injection mold with an inclined ejector block mechanism, comprising a main body box. A movable rod is fixedly installed on one side inside the main body box, and a driven sprocket is fixedly installed in the middle of the surface of the movable rod. A drive motor is fixedly installed on the back of the main body box, and a drive sprocket is fixedly installed on the output shaft of the drive motor. A transmission chain is connected to the surfaces of the driven sprocket and the drive sprocket, which allows for adjustment of the transmission chain to ensure chain tension.

[0004] However, due to the configuration of the drive sprocket and driven sprocket, the rotation stability of the drive sprocket and driven sprocket is low. When the chain is loose, the chain is easy to fall off the sprocket. At the same time, because the U-shaped plate is moved by two sets of electric push rods and the chain is tensioned by tilting angle, the use effect is poor and the cost of use is high.

[0005] Therefore, we propose a mechanical chain tension adjustment device. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a mechanical chain tension adjustment device, which solves the problems of low stability and poor performance of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a mechanical chain tension adjustment device, including a chain box, wherein a drive motor with a corresponding position is mounted on the inner wall of the rear side of the chain box; The output end of the drive motor is equipped with a shaft of the same specification, and the shaft is equipped with a drive gear of the same specification. The inner wall of the chain box is equipped with a driven rod of the opposite position through a bearing. The driven rod is equipped with a driven gear of the same specification. The outer walls of the drive gear and the driven gear are meshed with a chain of the same specification. The inner wall of the front side of the chain box is equipped with a limiting rod of the opposite position through a bearing. The limiting rod is connected to the drive gear. The inner wall of the chain box is fixedly installed with opposite fixed plates. An electric telescopic rod is fixedly installed on the bottom surface of the fixed plate. A fixed frame of the same specification is fixedly installed on the telescopic end of the electric telescopic rod. A connecting rod of the same specification is assembled on the inner wall of the fixed frame through a bearing. An adjusting gear of the same specification is assembled on the connecting rod. The adjusting gear meshes with the chain.

[0008] Preferably, the chain box is equipped with inspection doors on both the left and right sides, which facilitates the inspection and maintenance of the components inside the chain box.

[0009] Preferably, the chain box has an observation window on its front side, which is made of transparent glass, so as to facilitate observation of the chain tension.

[0010] Preferably, the chain box has evenly distributed heat dissipation holes on its upper and lower sides, which can improve the heat dissipation effect of the chain box.

[0011] Preferably, the outer walls of the driving gear, driven gear, and adjusting gear are fitted with an anti-rust layer to prevent the gears from rusting.

[0012] Preferably, the fixing plate is made of steel, which can improve its strength and prevent breakage.

[0013] This mechanical chain tension adjustment device, through the setting of a driven rod and a limiting rod, allows the limiting rod to limit the driving gear and the driven rod to limit the driven gear, preventing the driving gear and driven gear from wobbling back and forth and left and right, ensuring the stability of chain and gear meshing, preventing chain slippage, and improving the stability of use.

[0014] Meanwhile, through the setting of electric telescopic rod and adjusting gear, the electric telescopic rod drives the fixed frame to move downward, and the adjusting gear presses the chain downward, thereby tensioning the chain, ensuring the chain tension and improving the use effect.
