Description

Technical Field

[0001] The utility model relates to the technical field of line-aligning devices, in particular to an adjustable line-aligning device for aging testing of a force measuring instrument. Background Art

[0002] Power parameter measuring instruments typically need to display electrical parameters such as voltage, current, power, factor, and frequency, as well as various operating control states, on the instrument's front panel. However, after force measuring instruments are assembled, their service life needs to be measured batch by batch. Therefore, a bracket is required to perform simultaneous aging tests on all force measuring instruments.

[0003] The prior art discloses a patent with the publication number CN220872504U. The solution includes a support tube, on which a number of independently arranged winding drums are sleeved along the axial direction thereof, a connecting wire is wound on the winding drum, a power supply wire is provided inside the support tube, and two power connection rings are coaxially fixedly connected to the outer wall of the support tube corresponding to each winding drum, the power connection rings are connected to the power supply wire, and the inner wall of the winding drum is respectively provided with a conductive component connected to the power connection ring, one end of the connecting wire is connected to the conductive component, and the other end of the connecting wire is connected to the instrument plug. The utility model solves the problem in the traditional technology that due to the large number of instruments in the same batch of aging tests, the existing instruments are stacked on the bracket, which means that many power supply wires need to be connected during the power-on test, which makes it easy for adjacent power supply wires to be intertwined and disordered, thereby affecting the test efficiency.

[0004] The existing technologies including the above patents have gradually exposed their shortcomings as they are used, mainly in the following aspects:

[0005] First, after the existing device pulls out the wire, it is limited by the influence of the automatic winding structure, so that the connecting wire is always in a taut state, which makes it easy for the instrument plug to separate from the force measuring instrument during the test, resulting in the inability to supply power to the instrument normally, affecting the stability of the force measuring instrument during the aging test.

[0006] Second, the existing in-line tooling is fixed by fixing plates and brackets. Due to the different sizes of the brackets, the in-line tooling can only be assembled and matched with brackets of the same size, and cannot be matched with brackets of different sizes.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0008] In response to the defects in the existing technology, the utility model provides an adjustable wire-straightening device for aging testing of force measuring instruments, which is used to solve the problem that after the device in traditional technology pulls out the wire, it is limited by the influence of the automatic winding structure, so that the connecting wire is always in a tensioned state, which makes it easy for the instrument plug to separate from the force measuring instrument during the test, resulting in the inability to supply power to the instrument normally, affecting the stability of the force measuring instrument during the aging test.

[0018] As an optimized solution, two side rods are fixedly connected in parallel to the fixing plate, and the two side rods are hinged to the opposite outer walls of the square sleeve through a hinge shaft.

[0019] As an optimized solution, a power supply line is provided in the support tube, and two power connection rings are coaxially fixedly connected to the outer wall of the support tube corresponding to each of the winding drums, and the power connection rings are connected to the power supply line. Conductive components connected to the power connection rings are respectively provided on the inner wall of the winding drum, and the other end of the connecting line is connected to the conductive component.

[0020] As an optimized solution, an annular groove is fixed on the inner wall of the winding drum, and a torsion spring located in the annular groove is mounted on the support tube. Both ends of the torsion spring are respectively connected to the winding drum and the support tube.

[0022] As an optimized solution, the inner wire at one end of the connecting wire is correspondingly connected to the conductive sheet.

[0027] As an optimized solution, one end of the power supply line passes through the outer wall of the support tube and extends to the outside, and is connected to a power plug.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] Square plug-in rods are provided at both ends of the support tube, and square sleeves are slidably inserted on the square plug-in rods. The square plug-in rods and the square sleeves can be moved to match brackets of different widths for use, thereby increasing the scope of use. A swing-set fixing plate is hinged on the square sleeve, which can realize the swing setting of the fixing plate.

The lower end of the rectangular rubber sleeve is provided with a snap-in channel. When in use, the connecting wire is snapped into the rectangular rubber sleeve through the snap-in channel. The relative inner walls of the rectangular rubber sleeve can be used to clamp and fix the connecting wire, thereby reducing the influence of the tension of the torsion spring on the connecting wire, ensuring the stability of the connection between the instrument plug and the force measuring instrument, and ensuring the efficiency of the aging test process of the force measuring instrument.

[0031] When the force measuring instrument needs to be powered, pull out the connecting wire. One end of the connecting wire will be unwound under the rotation of the winding drum. Then insert the instrument plug into the corresponding force measuring instrument. It is convenient and quick. The position of the force measuring instrument can be selected to select the pulled-out length. It can effectively prevent the phenomenon of interweaving and disorder caused by the connecting wire being too long, and effectively ensure the orderliness of each connecting wire.

[0032] By providing a torsion spring between the winding drum and the support tube, the connecting wire can be automatically reeled up by utilizing the elasticity of the torsion spring when not in use;

[0033] The power supply line is connected to the power ring using branch wires, and the connecting wire uses conductive components to connect the power of the power supply line to the connecting wire. This structure ensures that when the winding drum rotates, only one end of the connecting wire is retracted and unreeled, while the other end is always fixed on the winding drum, which can prevent confusion caused by reeling and unreeling at both ends at the same time.

[0061] When the force measuring instrument needs to be powered, the connecting wire 3 is pulled out, and one end of the connecting wire 3 is unwound under the rotation of the winding drum 2, and then the instrument plug 15 is inserted into the corresponding force measuring instrument. It is convenient and quick, and the length of the pull-out can be selected according to the position of the force measuring instrument. It can effectively prevent the phenomenon of interweaving and disorder caused by the connecting wire 3 being too long, and effectively ensure the orderliness of each connecting wire 3;

[0062] By providing a torsion spring 8 between the winding drum 2 and the support tube 1, the connecting wire 3 can be automatically reeled up by utilizing the elasticity of the torsion spring 8 when not in use;

[0063] The power supply line 16 is connected to the power ring 5 using the branch wire 12, and the connecting wire 3 uses the conductive component 6 to connect the power of the power supply line 16 to the connecting wire 3. This structure ensures that when the winding drum 2 rotates, only one end of the connecting wire 3 is retracted and unreeled, and the other end is always fixed on the winding drum 2, which can prevent the confusion caused by the simultaneous reeling and unreeling of both ends.
