[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Reference Figure 1-6 The device for detecting the tension of a chain / belt includes a base 1, a bottom groove 2 on the bottom surface of the base 1, and a base plate 3 fixed to the bottom surface of the base 1 by bolts. A magnetic suction assembly is provided between the base plate 3 and the bottom groove 2. The function of the magnetic suction assembly is to directly attach the base 1 to a nearby sheet metal shell (the sheet metal shell is perpendicular to the Z-axis of the belt / chain) when detecting the belt / chain. A column 6 is provided on the top surface of the base 1, and a lifting assembly is provided on the column 6. A calibration assembly that works in conjunction with the lifting assembly is also provided on the column 6. In order to switch the fixed state of the calibration assembly according to the usage state, a switching assembly is provided on the calibration assembly. The switching assembly can change the fixed connection object of the calibration assembly.

[0025] As one implementation method in this embodiment, the magnetic suction assembly has a U-shaped magnet compartment 4 on the top surface of the base plate 3, which is adapted to the bottom groove 2. An electromagnet 5 and a battery for power supply are installed in the magnet compartment 4. When in use, the electromagnet 5 and the battery are installed in the magnet compartment 4 and connected to the sliding button 7 on the back of the column 6 through a wire. When in use, the current can be adjusted according to the sliding button 7 to control the attraction force of the electromagnet 5, so that the column 6 on the base 1 can be adjusted more conveniently and avoids the operator holding it for a long time.

[0026] As one embodiment of this example, the lifting assembly has a lifting groove 61 on the outer wall of the column 6, and a lifting rod 8 is rotatably connected in the lifting groove 61. A pressure block 10 is threaded onto the lifting rod 8, and the bottom surface of the pressure block 10 is an arc surface. The function of the arc surface is to reduce the friction when pressing down the belt / chain. A pressure sensor is provided on the bottom surface of the pressure block 10 so that the operator can quickly know the magnitude of the downward pressure. When in use, the rotating knob 9 on the top surface of the column 6 can be rotated to control the lifting of the pressure block 10.

[0027] When using the lifting component as described above, with the switching component connected, the calibration component moves up and down synchronously with the lifting component.

[0028] As one implementation method in this embodiment, the calibration component has a groove 62 on the outer wall of the column 6 and a slider on the outer wall of the connecting plate 14. The slider slides in the groove 62, and the two sets of connecting plates 14 are connected by a horizontal plate. The horizontal plate and the two sets of connecting plates 14 form a U-shape. A set of calibration elements 12 is provided on the opposite side of the connecting plate 14. The bottom surface of the calibration element 12 is flush with the bottom surface of the pressure block 10. When the pressure block 10 initially contacts the belt / chain, the limiting relationship between the calibration element 12 and the pressure block 10 is released by using the switching component, so that the connecting plate 14 is connected to the column 6, and the initial position of the belt / chain is recorded.

[0029] As one embodiment of this invention, the switching component has two sets of sliding holes 141 on the connecting plate 14, and the cross-section of the sliding holes 141 is convex. A set of positioning plugs 15 are slidably connected in the sliding holes 141 on both the front and rear sides. The length of the positioning plug 15 on the rear side is shorter than that of the positioning plugs 15 on the front and rear sides. The calibration component 12 has through holes 121 that correspond to the positions of the positioning plugs 15 and match the size. The pressure block 10 has a fixed groove 101 that matches the through holes 121. In use, the positioning plug 15 on the front side is passed through the through holes 121 and the fixed groove 101 in sequence to complete the fixed connection between the calibration component 12 and the pressure block 10. The positioning plug 15 on the rear side is pulled outward to avoid contact with the inner wall of the column 6.

[0030] When it is necessary to disconnect the calibration component from the lifting component, push the rear positioning plug 15 inward so that the damping pad on the inner end face of the positioning plug 15 is in close contact with the outer wall of the column 6, increasing the friction between the two. Pull the front positioning plug 15 outward to release the limit between the calibration component 12 and the pressure block 10.

[0031] As one embodiment of this invention, at least two sets of rubber rings 16 are fitted on the outer wall of the positioning plug 15 to increase friction during use.

[0032] As one embodiment of this example, a measuring scale 11 is provided on the outer wall of the pressure block 10, and a groove for the measuring scale 11 to slide is provided on the calibration component 12. An observation window 13 with a connecting groove is also provided on the calibration component 12. A magnifying glass is provided in the observation window 13 to facilitate the staff to know the lifting height.

[0033] Example 2: The difference between this example and Example 1 is that the positioning plug 15 is provided with a threaded section, and the positioning plug 15 is threadedly connected to the sliding hole 141. The function here is to act as a set screw.

[0034] The working principle of this utility model is as follows: By placing the base 1 against the sheet metal next to the belt / chain to be tested, and then moving the sliding button 7 to control the battery current, thereby controlling the magnetic force of the electromagnet 5, the base 1 is moved on the sheet metal until the outer wall of the column 6 is in contact with the belt / chain. Then, the sliding button 7 is pushed to the maximum position, and the rotary knob 9 is rotated. With the cooperation of the lifting rod 8 and the lifting groove 61, the pressure block 10 is raised and lowered within the lifting groove 61. During this process, the pressure block 10 drives the calibration component to rise and fall synchronously through the switching component. When the bottom of the pressure block 10 contacts the top surface of the belt / chain, the front sliding button is pulled. The positioning plug 15 inside the hole 141 moves outward, causing the rubber ring 16 to slide in the through hole 121 and move out of the fixed groove 101, thus releasing the connection between the calibration component 12 and the pressure block 10. Then, another set of positioning plugs 15 is pressed inward, and the positioning plugs 15 slide in the sliding hole 141 on the rear side, tightly pressing the outer wall of the column 6. Through friction, the calibration component is fixed on the column 6. Then, the rotary knob 9 is turned again, causing the pressure block 10 to move down. The pressure sensor at the bottom of the pressure block 10, together with the measuring ruler 11, measures the tension force of the belt / chain after it has descended a certain height, and then the corresponding tension force is adjusted.

[0035] The calibration piece 12 has an observation window 13 with a magnifying glass, which allows staff to quickly measure the descent height of the ruler 11.

[0036] A slider is provided on the inner wall of the connecting plate 14, and a groove 62 adapted to the slider is provided on the column 6. Its function is to stabilize the lifting state of the connecting plate 14 during the lifting process.

[0037] When the battery or electromagnet 5 needs to be replaced, remove the bottom plate 3 at the bottom of the base 1, then take out the electromagnet 5 and battery from inside the magnet compartment 4, and reinstall them after the replacement is completed.

[0039] Components not described in detail in this article are existing technologies.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
