Description

Technical Field

[0001] This utility model relates to the technical field of stress detection, and in particular to a handheld stress detector. Background Technology

[0002] In the field of stress testing, traditional stress testing instruments, while pursuing comprehensive functionality and testing accuracy, often neglect the important requirement of portability. These instruments typically have complex structures and large sizes, integrating multiple testing modules and data processing units to ensure coverage of a wide range of testing scenarios and provide accurate test results.

[0003] However, this design approach results in significant portability limitations for traditional stress testing instruments. Their large size and weight make it difficult for users to easily carry these devices to the field for testing. This not only increases transportation and installation costs for users but also limits the instrument's application range in complex or remote environments.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a handheld stress detector is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a handheld stress detector.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a handheld stress detector, comprising: a top block and two fixing plates, and a snap-fit ​​unit disposed on both sides of the two fixing plates;

[0007] A handle is fixedly connected to the bottom of the top block, and a bottom block is fixedly connected to the bottom of the handle;

[0008] Each of the two fixed plates has a rotating groove on one side facing each other. A connecting rod is rotatably connected between the inner walls of the two sides of the rotating groove. A rotating rod is fixedly connected to the outer circumference of the connecting rod. One end of the rotating rod is rotatably connected to one side of the top block.

[0009] In a preferred embodiment of this utility model, a mounting plate is fixedly connected to the other side of each of the two fixing plates, and a polarizer is provided in the mounting plate.

[0010] In a preferred embodiment of this utility model, the mounting plate and the fixing plate form a right angle.

[0011] In a preferred embodiment of this utility model, the snap-fit ​​unit consists of two magnetic blocks, which are respectively fixedly connected to both sides of one of the mounting plates, and both sides of the two mounting plates are fixedly connected to a fixing cylinder.

[0012] In a preferred embodiment of this utility model, the two fixed cylinders on the same side are slidably connected by the same insertion rod.

[0013] In a preferred embodiment of this utility model, an iron block is fixedly connected to one side of the insertion rod.

[0014] In a preferred embodiment of this utility model, the iron block is located between the magnetic block and one of the fixed cylinders.

[0015] In a preferred embodiment of this invention, the iron block is attracted to the magnetic block.

[0016] In a preferred embodiment of this invention, an anti-slip pad is adhered to the outer circumferential wall of the grip.

[0017] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0018] (1) This utility model provides a handheld stress detector. The magnetic block and iron block in the snap-fit ​​unit are slidably connected in the fixed cylinder, so that the device body can be easily folded and unfolded. When not in use, the user can fold the device into a compact cuboid shape with a simple operation, which greatly reduces the volume, makes it easy to carry and store, thereby improving the convenience of use and effectively saving space.

[0019] (2) This utility model provides a handheld stress detector, which can be operated by simply rotating the fixing plate and adjusting the snap-fit ​​unit. Furthermore, when the device is unfolded and fixed, the two fixing plates are on the same horizontal plane, ensuring the stability of the test. In addition, the attraction between the magnetic block and the iron block, as well as the locking of the insertion rod within the fixing cylinder, further enhances the stability of the device, preventing possible shaking or displacement during the test and improving the accuracy of the test.

[0020] (3) This utility model provides a handheld stress detector, which enhances the detection function by incorporating a polarizer. The polarizer helps users to observe and analyze the detection results more clearly. At the same time, the addition of an anti-slip pad improves the grip comfort and effectively prevents slippage during use. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] like Figure 1 As shown, a handheld stress detector includes: a top block 2 and two fixing plates 5, as well as snap-fit ​​units disposed on both sides of the two fixing plates 5;

[0028] like Figures 2-3 As shown, a handle 3 is fixedly connected to the bottom of the top block 2, and a bottom block 1 is fixedly connected to the bottom of the handle 3; a rotating groove 14 is provided on one side of each of the two fixed plates 5, and a connecting rod 13 is rotatably connected between the inner walls of the two sides of the rotating groove 14. A rotating rod 12 is fixedly connected to the outer circumference of the connecting rod 13, and one end of the rotating rod 12 is rotatably connected to one side of the top block 2. A mounting plate 6 is fixedly connected to the other side of each of the two fixed plates 5, and a polarizer 8 is provided in the mounting plate 6. The angle between the mounting plate 6 and the fixed plate 5 is a right angle.

[0029] The snap-fit ​​unit consists of two magnetic blocks 7, which are fixedly connected to both sides of one of the mounting plates 6. Fixing cylinders 9 are fixedly connected to both sides of the two fixing plates 5. The same insertion rod 11 is slidably connected between the two fixing cylinders 9 on the same side. An iron block 10 is fixedly connected to one side of the insertion rod 11. The iron block 10 is located between the magnetic blocks 7 and one of the fixing cylinders 9. The iron block 10 is attracted to the magnetic blocks 7. An anti-slip pad 4 is glued to the outer circumference of the handle 3.

[0030] It should be noted that the device body, through the arrangement of the top block 2, fixing plate 5, and snap-fit ​​unit, forms a compact and portable testing tool. The two fixing plates 5 are rotatably connected to the top block 2 via the rotating groove 14 and connecting rod 13, allowing the fixing plates 5 to be flexibly adjusted at the required angle for easy deployment and testing. Simultaneously, the polarizing plate 8 within the mounting plate 6 enhances the testing function, and the snap-fit ​​unit achieves a stable connection between the two fixing plates 5 through the attraction between the magnetic block 7 and the iron block 10, simplifying the operation and improving the stability of the device body during testing. Furthermore, the insertion rod 11 slides between the two fixing cylinders 9 on the same side, further enhancing the stability of the fixing plates 5. The outer circumference of the handle 3 is coated with an anti-slip pad 4, improving user comfort when holding the device body and effectively preventing the testing instrument from slipping due to hand slippage.

[0031] When using this invention, to unfold it, hold the top block 2 and the handle 3, and unfold the two fixing plates 5 to both sides. Since the fixing plates 5 are rotatably connected to the top block 2 through the rotating groove 14 and the connecting rod 13, after the fixing plates 5 are unfolded, rotate them 180°, pull the insertion rod 11 to separate the iron block 10 from the magnetic block 7, and insert the insertion rod 11 between the two fixing cylinders 9 on the same side to keep the fixing plates 5 stable. Ensure that the centers of the two polarizers 8 are aligned for accurate detection. At this time, the device body is fully unfolded and ready for detection. To fold it: First, pull the insertion rod 11 to slide it out between the two fixing cylinders 9, so that the iron block 10 attracts the magnetic block 7. Fold the two fixing plates 5 towards the middle. Due to the rotatable connection between the fixing plates 5 and the top block 2, one side of the fixing plates 5 is attached to both sides of the bottom block 1. When the two fixing plates 5 are completely attached to both sides of the bottom block 1, the mounting plates 6 will also be attached to each other.

[0032] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
