Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless stress strain testing technology, and in particular to a novel wireless stress strain testing device. Background Technology
[0002] The wireless stress strain testing device is a modern monitoring device that integrates high-precision sensing technology, wireless communication technology and intelligent data processing capabilities. It can capture the minute deformation of an object under the action of external force in real time, and indirectly reflect the stress state inside the object through the intrinsic relationship between strain and stress. Finally, it realizes remote data acquisition and analysis through wireless transmission.
[0003] The internal space of the wireless stress strain testing device is narrow, and the core components are mostly compactly stacked or embedded and fixed, with very small gaps between the components, and some key connection points are blocked by other components.
[0004] When the device malfunctions and needs repair, the staff must first remove multiple fixing screws on the casing and then carefully separate the internal components. Due to space constraints, conventional tools are difficult to operate in depth, and it is very easy to touch adjacent components and cause secondary damage. For welded or glued parts, destructive disassembly may even be required for repair, which not only prolongs the troubleshooting time but may also lead to the scrapping of the entire device. Utility Model Content
[0005] The purpose of this invention is to provide a novel wireless stress strain testing device to address the shortcomings of existing wireless stress strain testing devices, which have narrow internal spaces, making it inconvenient for staff to inspect and maintain the components installed inside.

[0023] The novel wireless stress strain testing device provided by this utility model has the following advantages:
[0024] This utility model, by setting an auxiliary structure, through the auxiliary cooperation between the guide groove and the protective cover, allows the guide block to slide inside the guide groove when the operator slides two sets of protective covers at the same time. When one end of the protective cover is in contact with the top of the fixing frame, the spring buckle can be engaged inside the limiting hole. This can assist the operator in inspecting the wireless transmission module installed inside the take-up and take-down frame, and provides the operator with relatively ample inspection space, making it convenient for the operator to operate with hand tools.
[0025] Based on the aforementioned beneficial effects, a protective structure is provided. Through the auxiliary cooperation between the fixed frame and the rotating gear, when the threaded rod rotates inside the fixed frame, the screw block can slide along the threaded trajectory outside the threaded rod inside the fixed frame. This can form a protective barrier at the front end of the device when the key to be tested is being tested, preventing external light from affecting the device and causing errors in the final data.

[0036] Please see Figures 1-5 This utility model provides a novel wireless stress strain testing device, comprising:
[0037] Auxiliary structure: The auxiliary structure is coaxially mounted on top of the test structure;
[0038] Test structure: The test structure includes a worktable 11, a fixed frame 12, a take-up and take-down frame 13, a strain sensor 14, and a signal processing module 15;
[0039] The fixed frame 12 is fixedly connected to the top of the workbench 11, the take-up and put-down frame 13 is fixedly connected to the top of the fixed frame 12, the strain sensor 14 is fixedly connected to the front end of the take-up and put-down frame 13, and the signal processing module 15 is fixedly connected to the outside of the take-up and put-down frame 13.
[0040] The test structure also includes a guide rail 16, a placement plate 17, and an electric telescopic rod 18;
[0041] The guide rail 16 is fixedly connected to the upper front end of the workbench 11, the electric telescopic rod 18 is fixedly connected to the front end of the workbench 11, and the placement plate 17 is fixedly connected to the connecting end of the electric telescopic rod 18.
[0042] When the object under test is deformed by external force, the strain sensor 14 converts the mechanical deformation into an electrical signal. The signal processing module 15 amplifies, filters and converts the original signal to A / D to ensure data accuracy. The processed digital signal is sent to the receiving terminal through the wireless transmission module installed inside the receiving frame 13. The transmission process uses an encryption algorithm to ensure data security.
[0043] Auxiliary structure: The auxiliary structure includes guide groove 21, protective cover 22, spring buckle 23, guide block 24 and limiting hole 25;
[0044] Guide grooves 21 are provided on both sides of the inner wall of the take-up and put-down frame 13, protective cover 22 is slidably connected to the top of the take-up and put-down frame 13, spring buckle 23 is fixedly connected to the inner side of one end of protective cover 22, guide block 24 is fixedly connected to both sides of one end of protective cover 22, and limiting hole 25 is provided at both ends of the fixing frame 12.
[0045] The auxiliary structure also includes a connecting groove 26 and a spring block 27;
[0046] Connecting grooves 26 are formed at the bottom of both ends of the fixed frame 12, and spring blocks 27 are slidably connected inside the connecting grooves 26;

[0048] With the auxiliary cooperation between the guide groove 21 and the protective cover 22, when the staff slides the two sets of protective covers 22 at the same time, the guide block 24 can slide inside the guide groove 21. When one end of the protective cover 22 is in contact with the top of the fixing frame 12, the spring buckle 23 can be engaged inside the limiting hole 25.
[0049] Working principle: When staff inspect the wireless transmission module installed inside the receiving and dispensing frame 13;
[0050] First, release the installation between the retractable frame 13 and the protective cover 22, and simultaneously slide the two sets of protective covers 22 so that the guide blocks 24 fixedly connected to both sides of one end of the protective cover 22 can slide inside the guide groove 21.
[0051] Next, when one end of the protective cover 22 is attached to the top of the fixing frame 12, the spring buckle 23 fixedly connected to one end of the protective cover 22 can be engaged inside the limiting hole 25, providing maintenance space for the staff.

[0052] This step can assist staff in inspecting the wireless transmission module installed inside the receiving and dispensing frame 13, and provides staff with ample space for inspection, making it convenient for staff to operate with hand tools.

[0057] The screw block 36 is threaded to the outside of the threaded rod 33, and the protective plate 35 is fixedly connected to the front end of the screw block 36;
[0058] The fixed frame 31 provides space for guiding the sliding of the screw block 36, and the rotating gear 32 and the toothed block 34 are meshed together;
[0059] With the auxiliary cooperation between the fixed frame 31 and the rotating gear 32, when the threaded rod 33 rotates inside the fixed frame 31, the screw block 36 can slide along the threaded trajectory outside the threaded rod 33 inside the fixed frame 31.
[0060] Working principle: When the electric telescopic rod 18 operates, it pushes the placement plate 17 to the bottom of the fixed frame 12;
[0061] First, the placement plate 17 can slide while simultaneously driving the toothed blocks 34 fixedly connected on both sides to slide, and the toothed blocks 34 and the rotating gear 32 can mesh and connect.
[0062] Next, as the rotating gear 32 rotates, it can drive the threaded rod 33 to rotate, and cause the screw block 36 to slide along the threaded trajectory outside the threaded rod 33 inside the fixed frame 31, thereby allowing the protective plate 35, which is fixedly connected to the screw block 36 at the rear, to slide down vertically and form protection at the front end of the fixed frame 12.
