Length measuring device with protection function for chain production

Abstract

The invention relates to the technical field of chain length measuring devices, in particular to a length measuring device with a protection function for chain production, which comprises an operation table, a measuring structure for measuring the length of a chain is arranged on the operation table, an identification structure for displaying a measuring result is arranged on the operation table, and the identification structure is connected to the measuring structure; a protection plate is vertically arranged on the operation table, and a first driving structure used for driving the measuring structure to tighten the chain is arranged on the protection plate; a height adjusting structure used for adjusting the height of the storage structure is arranged on the operation table, the height adjusting structure is rotationally connected with the storage structure, and a second driving structure used for driving the storage structure to rotate is arranged on the operation table; the first driving structure drives the measuring structure to unfold the chain, and the measuring structure drives the identification structure to visually display data, so that the length measurement of the chain is more convenient and faster.

Description

technical field [0001] The invention relates to the technical field of chain length measuring devices, in particular to a length measuring device with protection function for chain production. Background technique [0002] The chain is generally a metal link or ring, which is mostly used for mechanical transmission and traction. After the chain is assembled, it is necessary to measure the length of the chain to check whether the length of the chain meets the size requirements. When the length of the chain does not meet the requirements, it needs to be reassembled. . [0003] However, the traditional chain length measurement method is to straighten the chain through a stretching structure, and then measure it with a scale, usually manually (for example, a bicycle chain length test device is disclosed in the patent application number 201821695024.3) or The electric driving mode drives two gears, so that the gear drives the chain to straighten. The manual mode requires hand co...

[0003]However, the traditional chain length measurement method is to straighten the chain through the stretching structure, and then measure it with a scale, usually manually (for example, the application number is The patent of 201821695024.3 discloses a bicycle chain length test device) or an electric drive to drive two gears, so that the gears drive the chain to straighten, and the manual mode requires hand cooperation, which is not conducive to the operator to take accessories or tools, and It is easy to block the observation of the data, and the electric drive method is adopted. Although the stretching is realized automatically, it is highly dependent on electrical components and requires the use of a control unit. When the length of the chain does not correspond, it is easy to cause the chain to break, and there is no protective component. When the chain falls, it will hit the ground, causing injury to the ground or the operator. Most of the chain accessories are placed in the storage box of the operating table. Multiple storage boxes are placed randomly, which is low in safety and inconvenient to take the chain accessories. , affecting the assembly efficiency of the chain
