Description

Technical Field

[0001] This utility model relates to the technical field of hardness testing devices, specifically to a surface hardness testing device for metal material production. Background Technology

[0002] In order to ensure that the hardness of metal materials meets the standards during the production process, hardness testing devices are often used to test the surface hardness of metal materials. Hardness testing devices are special instruments used to measure the surface hardness of materials. They are divided into benchtop hardness testers and portable hardness testers. Benchtop hardness testers are mainly used in laboratories and have the advantage of high accuracy. Portable hardness testers are suitable for use in production workshops and can randomly test different metal materials in real time. They eliminate the cumbersome procedure of manually looking up hardness tables, which is a common feature of hardness testers in the past, and realize the true characteristics of intelligence and portability.

[0003] During the use of a portable hardness tester, the testing tip is exposed and is easily bumped or knocked by external objects, which can damage the testing tip, reduce the service life of the device, and cause great inconvenience to its normal use.

[0004] In summary, existing portable hardness testers lack protective mechanisms, making the testing tip highly susceptible to damage from collisions with external objects. Utility Model Content

[0005] The purpose of this invention is to provide a surface hardness testing device for metal materials, in order to solve the technical problem that most existing portable hardness testers lack a protective mechanism and the testing tip is easily damaged by collisions with external objects.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A surface hardness testing device for metallic materials includes a detector body.

[0008] A protective component is provided on one side of the bottom of the detector body. The protective component includes a housing, a protective base slidably disposed inside the housing, a housing groove opened on the top of the protective base, symmetrically opened inner grooves on the inner wall of the housing groove, and at least two sets of inner grooves, a positioning spring disposed inside the inner groove, a positioning block disposed at one end of the positioning spring that can slide along the inner wall of the inner groove, an arc-shaped fitting groove opened on the end face of the positioning block, and an anti-slip pad disposed on the surface of the arc-shaped fitting groove.

[0009] Preferably, the positioning block is in the shape of a right trapezoid, and the inclined surface of the positioning block faces upward.

[0010] Preferably, the detector body has a stepped slot on one side where the protective component is located, and the stepped slot is located on one side of the storage shell.

[0011] Preferably, the bottom wall of the housing is symmetrically provided with guide rails for limiting and guiding the movement of the protective base.

[0012] Preferably, the bottom of the protective base is provided with a limiting groove that matches the guide rail.

[0013] Preferably, the protective base is provided with a limiting baffle that matches the stepped slot on the side away from the storage shell.

[0014] Preferably, the detector body has a hinge seat on one side of the protective component, and the hinge seat is located above the protective component. A limit clamp is movably provided at one end of the hinge seat, and a flared plate is provided at the end of the limit clamp.

[0015] Preferably, the top of the detector body is electrically connected to an external terminal, and the top of the external terminal is electrically connected to a wire.

[0016] Preferably, the end of the wire is electrically connected to a handle that matches the limiting clamp, and the bottom end of the handle is electrically connected to a detection end that matches the anti-slip pad.

[0017] Preferably, the outer wall of the detector body is provided with a heat dissipation window for heat dissipation.

[0018] The beneficial effects of this utility model are:

[0019] 1. In this utility model, when the detection end is not in use, it can be inserted into the storage groove on the protective base. The positioning spring provides elastic support to the positioning block, which can slide along the inner wall of the groove. The inclined surface of the positioning block faces upward, which facilitates the insertion and positioning of the detection end. When the detection end is inserted into the protective base, the positioning block moves into the groove, and the positioning spring is compressed and deformed, thereby fixing the detection end well. The protective base can cover and protect the detection end, preventing it from being damaged or contaminated when not in use. This further reduces the probability of the detection end colliding with external objects, extends the service life of the detection end, and ensures the accuracy and safety of the test.

[0020] 2. In this utility model, the storage shell and the protective base are slidably connected, and the limiting clamp is rotatably set on the detector body through the hinge seat. When the device is in use, the protective base can be retracted into the storage shell, and the limiting clamp can be flipped to fit against the outer wall of the detector body, thereby greatly reducing the size of the device and further improving the flexibility of the device when in use.

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] like Figure 1-3 As shown, a surface hardness testing device for metal materials includes a detector body 1. The detector body 1 serves as the main part of the surface hardness testing device for metal materials, and is used to support and integrate other components. It contains a circuit board, a battery, and related detection modules to realize the detection function.

[0028] A protective assembly is provided on one side of the bottom of the detector body 1. The protective assembly includes a housing 2, a protective base 4 slidably disposed inside the housing 2, a housing groove 8 opened on the top of the protective base 4, and inset grooves 9 symmetrically opened on the inner wall of the housing groove 8, with at least two sets of inset grooves 9. A positioning spring 10 is disposed inside the inset groove 9, and a positioning block 11 disposed at one end of the positioning spring 10 and slidable along the inner wall of the inset groove 9. The positioning block 11 is in the shape of a right trapezoid with its inclined surface facing upward. An arc-shaped fitting groove 12 is opened on the end face of the positioning block 11 for close fitting. An anti-slip pad 13 is attached to the surface of the arc-shaped fitting groove 12. An external terminal 17 is electrically connected to the top of the detector body 1. A wire 18 is electrically connected to the top of the external terminal 17. A handle 19, matching the limiting clamp 15, is electrically connected to the end of the wire 18. A detection end 20, matching the anti-slip pad 13, is electrically connected to the bottom of the handle 19. In use, the device is simply attached to the metal surface by placing the detection end 20 against it. The storage shell 2 is located on the bottom side of the detector body 1, thus avoiding the need for internal circuit boards and related circuit components. This ensures the normal operation of the device. When the detection tip 20 is not in use, the operator can pull out the protective base 4 inside the storage shell 2 and then insert the detection tip 20 into the storage slot 8 on the protective base 4. The protective base 4 provides a protective cover for the detection tip 20, preventing damage or contamination when not in use. This further reduces the probability of the detection tip 20 colliding with external objects, extends the service life of the detection tip 20, and ensures the accuracy and safety of testing. The positioning spring 10 provides elastic support to the positioning block 11, making the positioning... Positioning block 11 can slide along the inner wall of the inner groove 9, and the inclined surface of positioning block 11 faces upward, which facilitates the insertion and positioning of the detection end 20. When the detection end 20 is inserted into the protective base 4, positioning block 11 moves into the inner groove 9, and positioning spring 10 is compressed and deformed, thereby forming a good fixation for detection end 20 and also facilitating the removal of detection end 20. The positioning block 11 has an arc-shaped fitting groove 12 for tightly fitting with detection end 20. Anti-slip pad 13 increases friction and prevents detection end 20 from falling off during storage.

[0029] In this embodiment, specifically, a stepped slot 3 is provided on one side of the detector body 1 where the protective component is located, and the stepped slot 3 is located on one side of the storage shell 2. A limiting baffle 7 matching the stepped slot 3 is provided on the side of the protective base 4 away from the storage shell 2. When the device is in use, the protective base 4 is retracted into the inside of the storage shell 2, and the limiting baffle 7 is inserted into the stepped slot 3 to fix the protective base 4.

[0030] In this embodiment, specifically, the bottom wall of the housing shell 2 is symmetrically provided with guide rails 5 for limiting and guiding the movement of the protective base 4, and the bottom of the protective base 4 is provided with a limiting groove 6 that matches the guide rails 5. The guide rails 5 and the limiting groove 6 cooperate with each other to ensure that the protective base 4 can slide along a predetermined trajectory.

[0031] In this embodiment, specifically, a hinge seat 14 is provided on the side of the detector body 1 where the protective component is provided, and the hinge seat 14 is located above the protective component. A limiting clamp 15 is movably provided at one end of the hinge seat 14, and a flared plate 16 is provided at the end of the limiting clamp 15. The limiting clamp 15 is movably provided on the detector body 1 through the hinge seat 14, which can stably fix the handle 19, ensuring the stability of the handle 19 and the detection end 20 when the detection end 20 is stored. When not in use, it can be flipped over, thereby reducing the overall volume of the device. The flared plate 16 facilitates the insertion of the handle 19.

[0032] In this embodiment, specifically, a heat dissipation window 21 is provided on the outer wall of the detector body 1 for heat dissipation. The design of the heat dissipation window 21 effectively reduces the temperature of the device during operation and prevents damage or performance degradation caused by overheating.

[0034] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
