Technical Field

[0001] The utility model relates to the technical field of alloy material detection, in particular to a detector for detecting alloy materials. Background Art

[0002] A hardness tester is a special instrument used to measure the surface hardness of coatings. In the current field of metal raw material processing, more and more customers require 100% hardness testing of purchased raw materials to ensure product quality. Therefore, alloy material testers are usually required.

[0003] For example, an existing patent (publication (announcement) number: CN207964449U) discloses an alloy material hardness tester, in which a dustproof door with a rotating shaft is arranged outside the button area and the display area above the main unit, so as to prevent dust from accumulating too much in the display area and making it inconvenient to clean.

[0004] However, the alloy material hardness tester designed as above still has some shortcomings in practical application: for example, although the alloy material hardness tester designed as above can play a dust protection effect, the dustproof door thereon needs to be rotated to one side of the main body when in use, which makes it inconvenient for the user to operate it with one hand, and the dustproof door cannot be opened with one hand when opening the above-mentioned dustproof door, which is inconvenient to use.

[0005] Therefore, we designed a detector for detecting alloy materials to solve the above problems. Utility Model Content

By allowing a person to hold the instrument body and push a pressing piece upward with his thumb, the dustproof plate can be moved upward and the iron sheet can be separated from the permanent magnet. At this time, the spring drives the connecting sleeve, the connecting piece and the dustproof plate to move upward due to its own elastic force and exposes the display screen. The whole process can be completed by a person with one hand, which is relatively convenient and solves the problems raised in the background technology.

[0007] In order to solve the above technical problems, the utility model provides a detector for detecting alloy materials, including an instrument body, a display screen and a circuit are respectively provided on the front side and the top of the instrument body, a detection head is connected to the other end of the circuit, and the detection head is electrically connected to the display screen, and two limit bars are symmetrically arranged on the front side of the instrument body, one of the limit bars is fixedly provided with a spring, and a connecting sleeve is fixedly installed on the other end of the spring, a connecting piece is provided on one side of the connecting sleeve, and a dustproof plate is provided on the other end of the connecting piece, the dustproof plate is located on the front side of the display screen, and an iron sheet is provided on the bottom of the dustproof plate, and a permanent magnet is commonly provided between the two limit bars, and the iron sheet is magnetically connected to the permanent magnet.

[0008] Preferably, a pressing piece is provided on the front side of the dustproof plate, and anti-slip texture is provided on the pressing piece, which can increase the friction between the person's hand and the pressing piece, thereby helping to solve the problem of slipping when sliding the dustproof plate.

[0022] The embodiments of the present utility model are described in detail below.

[0023] Embodiment 1

[0024] Depend on Figure 1-5A detector for detecting alloy materials is given, comprising an instrument body 1, a display screen 2 and a circuit 3 are respectively arranged on the front side and the top of the instrument body 1, a detection head 4 is connected to the other end of the circuit 3, and the detection head 4 is electrically connected to the display screen 2, two limit bars 5 are symmetrically arranged on the front side of the instrument body 1, a spring 11 is fixedly arranged in one of the limit bars 5, a connecting sleeve 8 is fixedly installed on the other end of the spring 11, a connecting piece 9 is arranged on one side of the connecting sleeve 8, a dustproof plate 10 is arranged on the other end of the connecting piece 9, the dustproof plate 10 is located on the front side of the display screen 2, an iron sheet 12 is arranged on the bottom of the dustproof plate 10, a permanent magnet 13 is commonly arranged between the two limit bars 5, the iron sheet 12 is magnetically connected to the permanent magnet 13, a slide groove 6 is opened on the front side of the limit bar 5, a guide rod 7 is fixedly installed in one of the slide grooves 6, the connecting sleeve 8 is slidably sleeved on the guide rod 7, and the two ends of the spring 11 are fixedly connected to the connecting sleeve 8 and the inner wall of the slide groove 6 respectively.

[0025] During the specific implementation, the personnel first holds the instrument body 1, and then pushes the pressing piece 22 upward with the thumb, so that the pressing piece 22 drives the dustproof plate 10 to move upward and separates the iron sheet 12 from the permanent magnet 13. At this time, the spring 11 pulls the connecting sleeve 8 back due to its own elastic force, so that the connecting piece 9 drives the dustproof plate 10 to move upward and expose the display screen 2. The whole process can be completed by the personnel with one hand, and then the detection head 4 is used to perform hardness detection on the alloy to be detected, and the detection result is fed back to the display screen 2 for personnel to view. When there is no need to use the detector of the alloy material, the personnel can adsorb the iron sheet 12 and the permanent magnet 13 according to the above principle to make the dustproof plate 10 protect the display screen 2 from dust.

[0026] A pressing piece 22 is provided on the front side of the dustproof plate 10, and an anti-skid pattern is provided on the pressing piece 22. The friction between the hand of the personnel and the pressing piece 22 can be increased, thereby helping to solve the problem of slipping when sliding the dustproof plate 10.

[0027] A fixing member 14 is fixedly installed on one side of the dustproof plate 10 away from the connecting member 9, and a placement groove 15 is opened on one side of the fixing member 14. A ball 16 is rotatably arranged in the placement groove 15, and the ball 16 is rollingly connected in another slide groove 6. During the movement of the dustproof plate 10, the fixing member 14 will drive the ball 16 to roll in another slide groove 6, which can not only limit the dustproof plate 10, but also change the sliding into rolling friction, reducing the friction force, thereby reducing the friction loss.

[0028] Embodiment 2

[0029] Depend on Figure 1-5It is given that, on the basis of the above embodiment, a replacement groove 17 is opened on one side of the dustproof plate 10, and a wiping cotton 18 is movably arranged in the replacement groove 17. The wiping cotton 18 is made of sponge material. A pin shaft 19 is fixedly arranged on the top of the dustproof plate 10, and a clamping piece 20 is rotatably sleeved on the pin shaft 19. The clamping piece 20 is abutted against the top of the wiping cotton 18. A clamping head 21 is arranged on the top of the pin shaft 19, and the clamping head 21 is abutted against the clamping piece 20.

[0030] In specific implementation, on the basis of the above-mentioned embodiment, during the up and down movement of the dustproof plate 10, the dustproof plate 10 will drive the wiping cotton 18 to rub on the display screen 2, thereby cleaning the display screen 2. When the wiping cotton 18 is covered with mud and needs to be replaced, rotate the clamp 20 to make the clamp 20 rotate around the pin shaft 19 to release the limit on the wiping cotton 18, and then pull the wiping cotton 18 upward to pull the wiping cotton 18 out of the replacement slot 17, so as to facilitate the replacement of the wiping cotton 18.

[0031] In addition, a pressure sensor is usually provided inside the detection head 4. When the pressure sensor is pressed on the alloy to be detected, the changes on the alloy surface can be observed based on the pressure value to judge the alloy's anti-extrusion ability, and its hardness can also be detected. Since the detection head 4 is a prior art, it will not be described in detail in this manual.

[0032] Working principle: First, connect all the electrical appliances involved in the instrument body 1 to an external power supply. We can set a battery on the rear side of the instrument body 1, and then electrically connect the battery and the electrical appliances involved in the instrument body 1 to the battery to facilitate the provision of power to the electrical appliances. Since setting a battery is a prior art, this manual will not explain it in detail. When the detector of the alloy material is needed, first, the person holds the instrument body 1, and then pushes the pressing piece 22 upward with the thumb, so that the pressing piece 22 drives the dustproof plate 10 to move upward and separates the iron sheet 12 from the permanent magnet 13. At this time, the spring 11 pulls the connecting sleeve 8 back due to its own elastic force, so that the connecting piece 9 drives the dustproof plate 10 to move upward and separate the iron sheet 12 from the permanent magnet 13. The dust plate 10 then moves upward and reveals the display screen 2. The whole process can be completed by a single hand. In addition, during the movement of the dust plate 10, the fixing member 14 will drive the ball 16 to roll in another slide groove 6, which can not only limit the dust plate 10, but also change the sliding into rolling friction, thereby reducing the friction force and thus reducing the friction loss. Then, the detection head 4 is used to perform hardness detection on the alloy to be detected, and the detection result is fed back to the display screen 2 for viewing by the personnel. When the detector of the alloy material is not needed, the personnel can adsorb the iron sheet 12 and the permanent magnet 13 according to the above principle to make the dust plate 10 play a dust-proof protection effect on the display screen 2.

[0033] In addition, during the up and down movement of the above-mentioned dustproof plate 10, the dustproof plate 10 will drive the wiping cotton 18 to rub on the display screen 2, thereby achieving a cleaning effect on the display screen 2. When the wiping cotton 18 is covered with mud and needs to be replaced, rotate the clamp 20 to make the clamp 20 rotate around the pin shaft 19 to release the limit on the wiping cotton 18, and then pull the wiping cotton 18 upward to pull the wiping cotton 18 out of the replacement slot 17, thereby facilitating the replacement of the wiping cotton 18.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
