[0002] The arc spring tension measuring instrument is an instrument used to measure the force generated by the spring and the elongation of the spring when it is subjected to tension. It is usually composed of a spring, a drive device, a measuring device and a display device. At present, when using the arc spring tension measuring device, there is an efficiency problem. When it is necessary to measure arc springs of different sizes, it is often necessary to replace the dedicated measuring component. This replacement process usually involves disassembling multiple bolts, which is not only time-consuming, but also increases the complexity of the operation. Utility Model Content

[0003] In order to overcome the above defects, the utility model provides an arc spring tension measuring device, which solves the problem that the measuring component replacement process usually involves disassembling multiple bolts, which is not only time-consuming but also increases the complexity of the operation.

[0012] 1. The arc spring tension measuring device is provided with a connecting column, a slide groove, a return spring, an extrusion block and a limit rod. When the measuring component needs to be replaced, the limit rod is pulled out, and then the two extrusion blocks are pressed. At this time, the extrusion block slides in the slide groove. Then, when the extrusion block completely slides into the slide groove, the measuring component can be taken out, and then the corresponding measuring component is clamped outside the connecting column. When the extrusion block is overlapped on the measuring component, the limit rod is then clamped in one of the extrusion blocks and then in the corresponding limit hole. At this point, the measuring component is quickly replaced without the need for bolts to fix it, thereby saving a lot of time.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: an arc spring tension measuring device, comprising a bottom plate 1, a display 2 is connected to the bottom plate 1, a fixing device 3 is connected to the bottom plate 1, a measuring assembly 4 is connected to the bottom plate 1, and a limiting device 5 is connected to the bottom plate 1. The limiting device 5 comprises a connecting plate 51, the connecting plate 51 is connected to the bottom plate 1, a top rod 52 is slidably connected in the connecting plate 51, a limiting plate 53 is connected to the top rod 52, and a reset spring 54 is provided on the outer sleeve of the top rod 52. By setting the reset spring 54, during the measurement process, the reset spring 54 applies elastic force to the limiting plate 53 to keep it stable. When the limiting plate 53 is released, the reset spring 54 applies elastic force to the limiting plate 53, and the elastic force drives the limiting plate 53 to move, so that it can be quickly reset.

[0022] One end of the return spring 54 is connected to the limit plate 53, and the other end of the return spring 54 is connected to the connecting plate 51. The top rod 52 is connected to an arc plate 55. A plurality of limit holes 6 are provided in the measuring assembly 4. The fixing device 3 includes a connecting column 31, which is slidably connected in the measuring assembly 4. The extrusion block 34 is slidably connected in the slide groove 32. The extrusion block 34 is overlapped on the measuring assembly 4, and the limit rod 35 is clamped in the limit hole 6.

[0023] Two slide grooves 32 are provided in the connecting column 31, and two pull-back springs 33 are connected in the slide grooves 32. By setting the pull-back springs 33, during the measurement process, the pull-back springs 33 apply elastic force to the extrusion block 34 to keep it stable. When the extrusion block 34 is released, the pull-back springs 33 apply elastic force to the extrusion block 34, and the elastic force drives the extrusion block 34 to move, thereby realizing rapid reset.

[0024] One end of the pull-back spring 33 is connected to an extrusion block 34. By setting the slide groove 32 and the extrusion block 34, the slide groove 32 cooperates with the extrusion block 34, so that the slide groove 32 limits the extrusion block 34, thereby preventing the extrusion block 34 from deflecting during the sliding process.

[0025] A limiting rod 35 is slidably connected inside an extrusion block 34. By setting the limiting hole 6 and the limiting rod 35, the limiting hole 6 cooperates with the limiting rod 35, so that the limiting rod 35 limits the limiting hole 6 to avoid deviation between the two.

[0026] The working principle of the utility model is:

[0027] When the measuring component 4 needs to be replaced, the limit rod 35 is pulled out, and then the two extrusion blocks 34 are pressed. At this time, the extrusion blocks 34 slide in the slide groove 32. Then, when the extrusion blocks 34 completely slide into the slide groove 32, the measuring component 4 can be taken out, and then the corresponding measuring component 4 is clamped outside the connecting column 31. When the extrusion blocks 34 are overlapped on the measuring component 4, the limit rod 35 is then clamped in one of the extrusion blocks 34, and then clamped in the corresponding limit hole 6. When the arc spring is placed in the measuring component 4, the limit plate 53 is pulled at this time. At this time, the limit plate 53 drives the push rod 52 to move. Then, when the arc spring is placed, the limit plate 53 is released at this time, and the reset spring 54 applies elastic force to the limit plate 53, and the elastic force drives the push rod 52 to move. At this point, the measurement and limitation of different arc springs are completed.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connection", "sliding connection" and "hinge" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
