[0014] The specific embodiment of the utility model will be further described below in combination with the drawings.

[0015] As Figs. 1-2 shown, a spring tension detection device, including control console 1, control console 1 is provided with two vertical rods 2, the upper end of two vertical rods 2 is connected through top plate 3, control console 1 and top plate 3 are provided with screw 4, top plate 3 is provided with motor 5 for driving screw 4 to rotate, screw 4 is screw-connected with base 6, the both sides of base 6 are provided with fixed plate 7 respectively, fixed plate 7 is slidably connected with vertical rod 2, two fixed plates 7 are provided with tension sensor 8 respectively, still include movable plate 9 slidably connected with two vertical rods 2, the both sides of movable plate 9 are screw-connected with bolt 10 respectively, one end of tension sensor 8 and movable plate 9 are provided with fixed seat 11 respectively, one side of fixed seat 11 and one side of top plate 3 are provided with hanging rod 12 respectively.

[0016] By rotating the bolt 10 on the movable plate 9, and by the friction between the end of the bolt 10 and the vertical rod 2, the movable plate 9 is fixed on the two vertical rods 2, thereby realizing the fixation of the movable plate 9.

[0017] When detecting the tension of the tension spring 17, it is necessary to determine whether the tension required by the tension spring 17 when stretched to a certain length meets the design requirements, such as the initial length of the tension spring 17 being 10 cm. When the tension spring 17 is stretched from 10 cm to 20 cm, whether the required tension meets the design range. If the value of the required tension exceeds the design range, it indicates that the tension detection of the tension spring 17 is unqualified.

[0018] When the tension of the different length of the tension spring 17 is detected, the position of the movable plate 9 on the vertical rod 2 is changed, so that the two ends of the tension spring 17 can be easily installed on the tension sensor 8 below and the hanging rod 12 on the fixed seat 11 of the movable plate 9 after the last tension spring 17 of the same specification is stretched to the predetermined length.

[0019] Specifically, when using the device, first, the motor 5 drives the screw rod 4 to rotate, and through the threaded connection of the screw rod and the base 6, and through the sliding connection of the fixed plate 7 and the vertical rod 2, the base 6 can move up and down along the screw rod 4, and the fixed plate 7 is driven to move by the movement of the base 6, so that the top rod on the upper tension sensor 8 and the hanging rod 12 on one side of the top plate 3 maintain a proper distance, so as to hang the tension spring 17 on the two hanging rods 12. After the installation of the tension spring 17 is completed, the motor 5 is started to drive the base 6 to move downward, so that the base 6 moves downward by a predetermined distance, and the tension spring 17 is elongated to a specific length. When the tension spring 17 is elongated to a specific length, the reading on the tension sensor 8 is observed through the display screen on the control console 1, and then recorded. When the tension spring 17 is stretched to a specific length, the distance between the hanging rod 12 on the lower tension sensor 8 and the hanging rod 12 on the fixed seat 11 of the movable plate 9 is just enough to easily install the tension spring 17. After the tension spring 17 is installed, the motor 5 is reversed to drive the base 6 to rise, and then the lower tension spring 17 is stretched. When the lower tension spring 17 is stretched to a specific length, the motor 5 stops working. At this time, the reading on the tension sensor 8 can be observed through the control console 1, and then recorded. When the tension spring 17 is stretched to a specific length, the upper tension spring 17 can be easily removed from the hanging rod 12, and a new tension spring 17 can be installed on the hanging rod 12, so as to realize the cycle detection of the tension spring 17.

[0020] The control console 1 has a display screen, and the two tension sensors 8 can display their respective readings on the display screen of the control console 1.

[0021] Further, the outer surface of the hanging rod 12 is provided with a groove 13. From top to bottom, there are a total of four hanging rods 12, of which the grooves 13 of the first and third hanging rods 12 are upwardly arranged, and the grooves 13 of the remaining two hanging rods 12 are downwardly arranged. Through the arrangement of the grooves 13, the stability of the tension spring 17 on the hanging rod 12 can be improved, and the safety of the tension spring 17 during tension detection can be improved.

[0022] Further, the two ends of the fixed plate 7 and the movable plate 9 are respectively provided with an extension cylinder 14 in sliding connection with the vertical column, and the bolt 10 on the movable plate 9 is arranged on the extension cylinder 14 at both ends of the movable plate 9, so as to improve the stability of the fixed plate 7 and the movable plate 9 when moving on the vertical rod 2.

[0023] Further, the control console 1 is provided with a cover 15, one side of the cover 15 is provided with an opening, a baffle 16 is rotatably connected to the opening of the cover 15, and the baffle 16 and the cover 15 can avoid the tension spring 17 being stretched from threatening the experimental personnel, so that the safety during tension detection is improved.

[0024] Further, the baffle 16 is made of colorless and transparent plastic material, so that the condition of the tension spring 17 during stretching can be observed.

[0025] In the description of the utility model, unless another definite provision and limitation, the term "installation", "connection", "connect" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through the intermediate medium, can be two elements inside the communication, for the ordinary skilled in the art, the above-mentioned term can be understood according to the specific meaning in the utility model.
