[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a general-purpose equipment measuring instrument, including a toothed plate 1, with a sliding tooth 11 sleeved on the outer side of the middle end of the toothed plate 1, and a measuring component 2 disposed inside one end of the toothed plate 1. The measuring component 2 includes an insert plate 21 inserted inside one end of the toothed plate 1, a flexible ruler 22 inserted inside the insert plate 21, and a rotating component 3 disposed inside one end of the flexible ruler 22. Auxiliary components 4 are disposed inside both ends of the insert plate 21, and a pulling component 5 is disposed at the end of the flexible ruler 22 away from the rotating component 3. Locking components 6 are disposed at both ends of the pulling component 5, and a fixing component 7 is disposed on the inner side of the end of the insert plate 21 close to the pulling component 5. When measuring arc-shaped or cylindrical parts in general-purpose equipment, the measuring component 2 and the rotating component 3 can be used in conjunction to measure them according to the measurement requirements, thereby improving the measurement range and ease of use.

[0024] like Figure 2 As shown, the rotating assembly 3 includes a flexible ruler 22 inserted into a rotating rod 31 fixedly connected to one end of the insert plate 21, with both ends of the rotating rod 31 rotatably connected to the inside of the insert plate 21. Torsion springs 32 are fixedly connected to the outer sides of both ends of the rotating rod 31, with one end of the torsion spring 32 fixedly connected to the insert plate 21. When the flexible ruler 22 is pulled, it drives the rotating rod 31 to rotate, thereby stretching the torsion spring 32. Subsequently, the elastic potential energy of the torsion spring 32 is used to pull the rotating rod 31 to rotate and rewind the flexible ruler 22.

[0025] like Figure 2 As shown, the auxiliary component 4 includes rollers 41 inserted inside both ends of the insert plate 21, and a positioning rod 42 is inserted inside the rollers 41, with both ends of the positioning rod 42 fixedly connected to the insert plate 21.

[0026] like Figure 2 As shown, the pulling component 5 includes a baffle 51 fixedly connected to the end of the flexible ruler 22 away from the insert plate 21, and a handle 52 fixedly connected to the end of the baffle 51 away from the flexible ruler 22. Pulling the handle 52 drives the baffle 51, thereby allowing the baffle 51 to drive the insert plate 21 to be pulled by the resistance of the insert block 61, the locking ball 62 and the insert plate 21.

[0027] like Figure 4 As shown, the locking assembly 6 includes a baffle 51 with two fixedly connected insert blocks 61 on the side near the toothed plate 1. The end of the insert block 61 away from the baffle 51 is inserted into the insert plate 21. A locking ball 62 is inserted into one end of the insert block 61. A spring 63 is fixedly connected to the end of the locking ball 62 inserted into the insert block 61. The end of the spring 63 away from the locking ball 62 is fixedly connected to the insert block 61. Pushing the baffle 51 causes the insert block 61 to be inserted into the flexible ruler 22. At this time, the flexible ruler 22 is used to press the locking ball 62, thereby allowing the locking ball 62 to be inserted into the insert block 61 and compressing the spring 63. After the insert block 61 is inserted, the elastic potential energy of the spring 63 pushes the locking ball 62 out and inserts it into the insert plate 21 to lock the baffle 51 and the handle 52.

[0028] like Figure 4 As shown, the end of the ball 62 away from the spring 63 is spherical, and the end of the ball 62 away from the spring 63 is inserted into the insert plate 21.

[0029] like Figure 4 As shown, the fixing assembly 7 includes a fastening bolt 71 with internal threads engaged at one end of the insert plate 21 near the baffle 51, and the fastening bolt 71 is disposed through the toothed plate 1 at the end away from the insert plate 21. An anti-slip pad 72 is sleeved on the outer side of the end of the fastening bolt 71 away from the insert plate 21. The anti-slip pad 72 is sleeved on the outer side of the fastening bolt 71, and then the fastening bolt 71 is screwed through and into the toothed plate 1 and the insert plate 21 for fixing.

[0030] Working principle: When measuring the arc-shaped or cylindrical parts of the equipment, the handle 52 can be pulled directly to drive the baffle 51, which in turn pulls the insert block 61 and the flexible measuring tape 22. The flexible measuring tape 22, when pulled, causes the rotating rod 31 to rotate, thus stretching the torsion spring 32. After the insert block 61 is pulled, the locking ball 62, through the locking mechanism of the insert plate 21, is pressed into the insert block 61, compressing the spring 63. Subsequently, the flexible measuring tape 22 is pulled out from the insert plate 21 and the toothed plate 1. Then, the flexible measuring tape 22 can be used to measure curved and cylindrical objects. After the measurement, release the pull handle 52. The elastic potential energy of the torsion spring 32 pulls the rotating rod 31 to rotate, thereby allowing the rotating rod 31 to retract the flexible measuring tape 22. Finally, push the baffle 51 to drive the insert block 61 into the flexible measuring tape 22. At this time, the flexible measuring tape 22 presses down on the locking ball 62, thereby allowing the locking ball 62 to be inserted into the insert block 61 and compressing the spring 63. The insertion block 61 is then inserted. After the spring 63 is engaged, the elastic potential energy of the spring 63 pushes the ball 62 to pop out and insert into the insert plate 21, locking the baffle 51 and the handle 52 in place. If the insert plate 21 needs to be removed or replaced later, first loosen the fastening bolt 71 to remove the insert plate 21 and the toothed plate 1. Then pull the handle 52 to move the baffle 51. This allows the baffle 51 to pull the insert plate 21 by utilizing the resistance between the insert block 61, the ball 62, and the insert plate 21. Then, by driving the roller 41 and the positioning rod 42 to move, the roller 41 moves and rolls in contact with the toothed plate 1 under the positioning of the positioning rod 42, thereby assisting the insert plate 21 to pull out the toothed plate 1 for removal. After removal, the insert plate 21 is inserted into the toothed plate 1 with the assistance of the roller 41 and the positioning rod 42. After installation, the anti-slip pad 72 is placed on the outside of the fastening bolt 71, and then the fastening bolt 71 is screwed through and into the toothed plate 1 and the insert plate 21 for fixation.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
