[0025] See also Figure 1-4 The utility model provides a technical solution: a heavy-duty draw-wire encoder, comprising a mounting plate 1, a positioning mechanism 6 and a fixing mechanism 5. An encoder body 2 is arranged inside the mounting plate 1, and an annular plate 3 is fixedly installed on the outer surface of the encoder body 2. The annular plate 3 is fitted to the bottom of the mounting plate 1. A protective shell 4 is sleeved on the encoder body 2. The positioning mechanism 6 is arranged at the bottom of the mounting plate 1. The positioning mechanism 6 is used to disassemble and assemble the encoder body 2. At least two groups of mounting holes 7 are opened through the mounting plate 1, two groups of handle grooves 8 are opened through the mounting plate 1, and at least two groups of positioning holes are opened through the annular plate 3.

At least two groups of anti-slip strips 10 are fixedly installed on the outer surface of the protective shell 4.

[0026] The fixing mechanism 5 is arranged at the bottom of the annular plate 3, and the fixing mechanism 5 includes a rotating rod 51, a movable rod 52 and a clamping plate 53. The rotating rod 51 is rotatably installed at the bottom of the encoder body 2, and a movable groove is provided at the bottom of the rotating rod 51. The movable rod 52 is movably provided in the movable groove, and a clamping plate 53 is fixedly installed at one end of the movable rod 52. A groove matching the size of the clamping plate 53 is provided at the bottom of the protective shell 4, and the clamping plate 53 is clamped in the groove.

[0027] The fixing mechanism 5 also includes a first spring 54. The first spring 54 is arranged in the movable groove. One end of the first spring 54 is fixedly connected to the other end of the movable rod 52, and the other end of the first spring 54 is fixedly connected to the inner wall of the movable groove. Through the cooperation of the protective shell 4 and the fixing mechanism 5, the encoder body 2 can be protected to prevent the harsh environment from directly acting on the encoder body 2, thereby extending the service life of the encoder body 2. This solves the problem that some existing encoders are exposed to the outside and are easily corroded when used in harsh environments, resulting in a shortened service life. This reduces the cost of maintenance and replacement and improves the practicality of the encoder.

[0028] The positioning mechanism 6 includes a fixed plate 61, a connecting rod 62, an L-shaped block 63, a second spring 64 and a connecting block 65. Two sets of fixed plates 61 are fixedly installed at the bottom of the mounting plate 1. A set of connecting rods 62 are movably passed through the two sets of fixed plates 61. One end of the two sets of connecting rods 62 is fixedly installed with a set of L-shaped blocks 63. The annular plate 3 is clamped between the two sets of L-shaped blocks 63. The other ends of the two sets of connecting rods 62 are fixedly installed with a set of connecting blocks 65. A set of second springs 64 are sleeved on the two sets of connecting rods 62. One end of the two springs 64 is fixedly connected to the corresponding L-shaped block 63, and the other ends of the two groups of second springs 64 are fixedly connected to the corresponding fixed plate 61. Through the cooperation of the annular plate 3 and the positioning mechanism 6, the encoder body 2 can be quickly installed on the mounting plate 1, which is convenient for disassembly and assembly for maintenance or replacement. At the same time, under the action of the positioning block 9, the installation of the encoder body 2 can be quickly positioned, which improves the installation speed of the encoder body 2, ensures the use effect of the encoder, and is conducive to the promotion and use of the encoder.

[0029] Working principle: When in use, install the mounting plate 1 through the mounting hole 7, and the protective shell 4 protects the encoder body 2. When the encoder body 2 needs to be replaced, pull the two sets of connecting blocks 65, and each drive the two sets of L-shaped card blocks 63 to move through the corresponding connecting rods 62. The two sets of L-shaped card blocks 63 compress each second spring 64 until the two sets of L-shaped card blocks 63 release the positioning of the annular plate 3, and then the annular plate 3 together with the encoder body 2 can be removed for repair or replacement. When the protective shell 4 is damaged during long-term use, pull down the card plate 53, which slides on the rotating rod 51 through the movable rod 52 and stretches the first spring 54 until the card plate 53 is out of the groove on the protective shell 4, and then rotate the rotating rod 51 to turn the card plate 53 aside, and remove the protective shell 4 for a new one.
