Therefore, they can only be used to test stabilizer bars of a single specification. Since stabilizer bars vary in model and diameter depending on the vehicle, this limits the applicability of existing testing devices. To address this, we propose a tensile testing device.

[0017] 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.

[0018] Please see Figure 1-4 A tensile testing device includes a workbench 1, a motor 2 fixedly mounted on the outer wall of the workbench 1, a lead screw 4 fixedly mounted on the output shaft of the motor 2, a slide groove 3 formed on the top of the workbench 1, a slide block 5 threadedly connected to the outer wall of the lead screw 4, a display screen 9 fixedly mounted on the top of the workbench 1, a control panel 8 and a controller 10 fixedly mounted on the front of the workbench 1, and a button 11 also provided on the front of the workbench 1. A housing 6 is fixedly mounted on the top of both the workbench 1 and the slide block 5, and the inner wall of the housing 6 is slidably connected to... The pressure detection plate 12 is provided. A screw 14 runs through the inner wall of the housing 6. A knob 7 is fixedly mounted on the top of the screw 14. A straight groove 13 is opened in the middle of the housing 6. A rotating groove 19 and a circular groove 20 are opened on the inner wall of the straight groove 13. A tension spring 18 and a pressure sensor 21 are respectively provided on the inner wall of the housing 6. A positioning plate 17 is fixedly mounted on the side wall of the pressure detection plate 12 near the tension spring 18. A rotating rod 16 is rotatably connected to the outer wall of the positioning plate 17. A connecting block 15 is fixedly mounted on the outer wall of the screw 14.

[0019] In the above structure, the workbench 1, motor 2, slide 3, lead screw 4, slide block 5, housing 6, knob 7, straight groove 13, screw 14, connecting block 15, and rotating rod 16 are arranged so that during use, the user can rotate the knob 7 to raise and lower the connecting block 15 along the inner wall of the straight groove 13, thereby causing the rotating rod 16 to rotate and drive the pressure detection plate 12 to move horizontally, thus adjusting the distance between the two pressure detection plates 12. The movement of the slide block 5 ensures that the device is suitable for testing balance bars of different sizes, thereby improving the range of applications of the device.

[0020] In a preferred embodiment, the outer wall of the rotating rod 16 is rotatably connected to the inner wall of the rotating groove 19, and the end of the rotating rod 16 away from the positioning plate 17 is rotatably connected to the outer wall of the connecting block 15.

[0021] In the above structure, the rotating rod 16 allows the user to rotate the knob 7 to adjust the distance between the two pressure detection plates 12, eliminating the need for the user to move the pressure detection plates 12 to complete the adjustment. This improves the practicality of the device and the user's work efficiency.

[0022] In a preferred embodiment, there are four connecting blocks 15, which are divided into two groups, and both groups of connecting blocks 15 are symmetrically distributed along the outer wall of the screw 14.

[0023] In the above structure, the four connecting blocks 15 allow the pressure detection plate 12 to be adjusted by the pushing action of a rotating rod 16 at both ends, thus ensuring that the pressure detection plate 12 will not tilt or even shift its position during movement, thereby improving the stability of the pressure detection plate 12 during movement.

[0024] In a preferred embodiment, the end of the tension spring 18 away from the pressure sensor 21 abuts against the outer wall of the pressure detection plate 12, and the housing 6 is made of galvanized iron metal.

[0025] In the above structure, galvanized iron has the characteristics of hardness and wear resistance, which can effectively reduce the wear of the housing 6 during operation. The pressure detection plate 12 detects the strength of the balance rod by the pressure generated between the inner diameter of the balance rod and the pressure detection plate 12 due to the tension, thereby achieving the detection effect. At the same time, galvanized iron also has the characteristics of low cost, thereby reducing the production and maintenance costs of the device.

[0026] In a preferred embodiment, the inner wall of the slide groove 3 is slidably connected to the outer wall of the slide block 5, and there are two pressure detection plates 12, both of which are symmetrically distributed along the outer wall of the housing 6. The outer wall of the pressure detection plate 12 is provided with an anti-slip layer.

[0027] In the above structure, the two pressure detection plates 12 ensure that the balance bar will not tilt or detach from the device due to the increased friction caused by the anti-slip layer, thus ensuring the stability of the balance bar during the testing process and preventing the balance bar from detaching from the housing 6 and flying off due to the tension. This improves the safety of the device during the testing process.

[0028] In a preferred embodiment, the interior of the straight groove 13 is connected to the inner wall of the housing 6 via the rotating groove 19, and the pressure sensor 21 is electrically connected to the pressure detection plate 12.

[0029] In the above structure, the pressure detection plate 12 and pressure sensor 21 are configured so that when any pressure detection plate 12 is compressed, it can transmit data through the pressure sensor 21, thereby realizing the effect of detecting the pressure generated by the balance bar on the pressure detection plate 12, and thus realizing the function of detecting the strength of the balance bar.

[0030] In a preferred embodiment, the control panel 8 is electrically connected to the controller 10, the pressure sensor 21 is electrically connected to the display screen 9 and the controller 10 respectively, and the button 11 is electrically connected to the controller 10.

[0031] In the above structure, through the set display screen 9 and controller 10, after the pressure data detection is completed, the data before the balance bar breaks is displayed on the display screen 9, which makes it convenient for users to collect the detection data, organize and collect the detection results, and further improves the practicality of the device.

[0032] In a preferred embodiment, the inner wall of the straight groove 13 is threaded to the outer wall of the screw 14, and there is a 1cm gap between the outer wall of the screw 14 and the inner wall of the circular groove 20.

[0033] In the above structure, through the set circular groove 20 structure, after the screw 14 rises and part of it enters the circular groove 20, due to the reduction of the contact area between the screw 14 and the straight groove 13, the user can clearly feel the reduction in the force required when turning the knob 7, so that the user knows the degree of adjustment of the pressure detection plate 12, and thus facilitates the user to complete the adjustment of the position of the pressure detection plate 12.

[0034] Working principle: After assembling the device, the user can first adjust the position of the slide 5 by operating the motor 2, thereby achieving the effect of testing balance bars of different lengths. After adjustment, turn the knob 7 to make the screw 14 rise and fall along the inner wall of the straight groove 13, thereby adjusting the distance between the two pressure detection plates 12, ensuring that balance bars of different diameters can be tested by the device, thus improving the range of applications of the device. During the testing process, the reverse movement of the slide 5 causes the end of the balance bar closest to the motor 2 to be pulled, thereby causing the inner diameter of the balance bar to exert pressure on the outer wall of the pressure detection plate 12. At this time, the data will be collected by the pressure sensor 21 and displayed on the display screen 9, allowing the user to collect the data, thus facilitating user operation and improving the practicality of the device.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
