Description

Technical Field

[0001] This utility model relates to the field of geological exploration equipment, and more specifically, to a safety protection device for a mining display screen. Background Technology

[0002] A handheld energy-dispersive X-ray fluorescence spectrometer is a portable detection device based on X-ray fluorescence spectroscopy technology, widely used in geological exploration, mineral prospecting, and rapid analysis of ore composition in the field. This analyzer is typically equipped with a display screen, operating buttons, and a handheld handle, facilitating immediate testing and data reading of ore samples by field personnel.

[0003] Because the field working environment is complex and changeable, factors such as strong light, rain, and dust can easily interfere with the clarity of the display screen or even damage the equipment. Therefore, some existing analyzers have added protective mechanisms, such as light shields or waterproof covers, to the outside of the display screen to improve the outdoor adaptability and ease of reading of the equipment.

[0004] In the prior art, Chinese utility model patent with publication number CN217212354U discloses a handheld energy dispersive ore analyzer. Its protective components include a light shield, which is rotatably connected to the clamping component. It needs to be manually rotated to a suitable angle to achieve the light shielding or protective function. However, in actual use, while holding the analyzer handle, the operator often needs to manually open or close the protective cover with the other hand. The operation is cumbersome. Especially during field testing, operators often wear gloves or work in narrow and unstable terrain. Manually opening and closing the cover not only affects the testing efficiency, but also makes it easy for the cover to not be fully opened or not closed in time due to the inconvenience of operation, thus affecting the reading or reducing the protective effect. In addition, if the operator forgets to manually close the cover after testing, the display screen will be exposed to dust, rain or strong light for a long time, increasing the risk of equipment damage. In view of this, we propose a safety protection device for mining display screens to solve the above problems. Utility Model Content

The two second synchronous pulleys are respectively fixedly sleeved on the fourth rotating shaft and the outside of the second rotating shaft. A second synchronous belt is sleeved on the outside of the two second synchronous pulleys.

[0011] As a preferred technical solution of this application, the driving mechanism includes two arc-shaped plates, both of which are located outside the handle.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] Please refer to Figures 1-8 A safety protection device for a mining display screen includes an analyzer body 1, a display screen 2 mounted on the rear side of the analyzer body 1, a handle 3 fixedly connected to the lower surface of the analyzer body 1, a mounting plate 4 detachably mounted on the upper side of the analyzer body 1, a first groove 5 formed on the upper surface of the mounting plate 4, a first rotating shaft 6 rotatably connected inside the first groove 5, a cover plate 7 fixedly fitted outside the first rotating shaft 6, rectangular blocks 8 with square cross-sections on the surfaces of the two vertical plates of the mounting plate 4, and a second rotating shaft 9 rotatably mounted inside the housing of the analyzer body 1. Two second grooves 10 are provided on the surface. The second grooves 10 are adapted to the rectangular block 8. After the rectangular block 8 is inserted into the second groove 10, the rectangular block 8 will be coaxial with the second rotating shaft 9. Thus, when the rectangular block 8 rotates, it can smoothly drive the second rotating shaft 9 to rotate. Two first cavities 11 are provided inside the mounting plate 4. A first transmission mechanism is provided inside the first cavity 11. Two first fixing plates 12 are fixedly connected to the surface of the analyzer body 1. A second cavity 13 is provided inside the first fixing plate 12. A second transmission mechanism is provided inside the second cavity 13. A drive mechanism is provided outside the handle 3.

[0022] Furthermore, such as Figures 1-8 As shown, the first transmission mechanism includes a third rotating shaft 17, which is rotatably connected inside the first cavity 11. The two third rotating shafts 17 have their adjacent ends rotatably extending through the interior of the first cavity 11. The two third rotating shafts 17 are respectively fixedly connected to two rectangular blocks 8.

[0023] Furthermore, such as Figures 1-8 As shown, the first transmission mechanism also includes two first synchronous pulleys 18. The two ends of the first rotating shaft 6 are respectively rotatably inserted into the interior of the two first cavities 11. The two first synchronous pulleys 18 are respectively fixedly sleeved on the outside of the first rotating shaft 6 and the third rotating shaft 17. The outside of the two first synchronous pulleys 18 is sleeved with a first synchronous belt 19.

[0024] With this configuration, the second groove 10 and the rectangular block 8 work together to rotate the rectangular block 8 when the second rotating shaft 9 rotates. The rotation of the rectangular block 8 will then drive the rotation of the third rotating shaft 17. At this time, the first rotating shaft 6 will be driven to rotate under the transmission of the two first synchronous pulleys 18 and the first synchronous belt 19, which in turn will drive the cover plate 7 to rotate.

[0025] Furthermore, such as Figures 1-8As shown, two circular plates 28 are fixedly sleeved on the outside of the second rotating shaft 9. A torsion spring 29 is fixedly connected between the circular plates 28 and the surface of the analyzer body 1 housing. The torsion spring 29 is movably sleeved on the outside of the second rotating shaft 9.

[0026] With this setup, when the second rotating shaft 9 rotates, it will drive the circular plate 28 to rotate. At this time, the torsion spring 29 will produce a corresponding deformation, so as to assist the second rotating shaft 9 to reset later, so that the opening of the second groove 10 faces upward, making it convenient to disassemble the mounting plate 4.

[0027] Furthermore, such as Figures 1-8 As shown, the second transmission mechanism includes a fourth rotating shaft 14, which is located between two first fixed plates 12. Both ends of the fourth rotating shaft 14 are rotatably inserted into the interior of two second cavities 13. Both first fixed plates 12 are rotatably sleeved on the outside of the second rotating shaft 9. Two second synchronous pulleys 15 are arranged inside the second cavity 13. The two second synchronous pulleys 15 are fixedly sleeved on the outside of the fourth rotating shaft 14 and the second rotating shaft 9, respectively. A second synchronous belt 16 is sleeved on the outside of the two second synchronous pulleys 15.

[0028] With this setup, the rotation of the second shaft 9 can be driven by the rotation of the fourth shaft 14 and the cooperation between the second synchronous pulley 15 and the second synchronous belt 16.

[0029] The fourth rotating shaft 14 is located in the groove on the upper surface of the handle 3, so there will be no interference.

[0030] Furthermore, such as Figures 1-8 As shown, the drive mechanism includes two arc-shaped plates 24, both of which are located outside the handle 3. Guide rods 25 are fixedly connected to the adjacent surfaces of the two arc-shaped plates 24. Two movable chambers 26 are opened inside the handle 3. The two guide rods 25 slide through the interior of the two movable chambers 26 respectively, and a return spring 27 is fixedly connected between the guide rods 25 and the inner wall of the movable chambers 26.

[0031] With this setup, when the staff needs to use the analyzer body 1, they will press the two arc plates 24 towards the middle when they hold the handle 3. At this time, the two arc plates 24 will be completely in contact with the surface of the handle 3, and the guide rod 25 will slide inside the movable chamber 26, thereby causing the reset spring 27 to undergo elastic deformation.

[0032] Furthermore, such as Figures 1-8 As shown, a second fixing plate 20 is movably provided on the surface of the fourth rotating shaft 14, and a sleeve 21 is fixedly connected to the surface of the second fixing plate 20. The sleeve 21 and the fourth rotating shaft 14 are movably engaged, and the second fixing plate 20 is fixedly connected to the left arc plate 24.

[0033] With this setup, when the arc plate 24 is forced to move, the left arc plate 24 will drive the second fixed plate 20 and the sleeve 21 to move laterally outside the fourth rotating shaft 14.

[0034] Furthermore, such as Figures 1-8 As shown, a spiral groove 23 is provided on the surface of the fourth rotating shaft 14, and a sliding block 22 is fixedly connected to the inner arc surface of the sleeve 21. The sliding block 22 and the spiral groove 23 are in sliding fit.

[0035] With this setup, when the two arc-shaped plates 24 move closer together and drive the sleeve 21 to move, the fourth rotating shaft 14 will rotate counterclockwise under the cooperation of the sliding block 22 and the spiral groove 23. Subsequently, the second rotating shaft 9 will also rotate counterclockwise. The counterclockwise rotation of the second rotating shaft 9 will drive the third rotating shaft 17 to rotate counterclockwise. The counterclockwise rotation of the third rotating shaft 17 will drive the first rotating shaft 6 to rotate counterclockwise, thereby causing the cover plate 7 to open.

[0036] The usage process of the safety protection device for mining display screens provided by this utility model is as follows: First, when the operator needs to operate the analyzer body 1 and read the display screen 2, the operator's natural grip on the handle 3 will trigger the automatic opening process of the entire safety protection device. The operator's fingers press inward on the two arc-shaped plates 24 located outside the handle 3, causing the two arc-shaped plates 24 to come closer to each other and fit against the surface of the handle 3. During this process, the guide rod 25, which is fixedly connected to the arc-shaped plate 24, slides inward along the movable chamber 26 inside the handle 3 and compresses the return spring 27, causing the return spring 27 to generate elastic deformation and accumulate rebound force. At the same time, the second fixing plate 20 and the sleeve 21, which are fixedly connected to the left arc-shaped plate 24, move together with the arc-shaped plate 24 along the axial direction of the fourth rotating shaft 14.

[0037] As the sleeve 21 moves laterally along the surface of the fourth rotating shaft 14, the sliding block 22, which is fixedly connected to the inner arc surface of the sleeve 21, slides in the spiral groove 23 opened on the surface of the fourth rotating shaft 14. Since the spiral groove 23 has a guiding function, the linear motion of the sliding block 22 is converted into the counterclockwise rotational motion of the fourth rotating shaft 14. The counterclockwise rotation of the fourth rotating shaft 14 is transmitted to another second synchronous wheel 15 fixedly fitted on the outside of the second rotating shaft 9 through the second synchronous wheel 15 and the second synchronous belt 16, thereby driving the second rotating shaft 9 to rotate synchronously counterclockwise.

[0038] When the second rotating shaft 9 rotates, the two second grooves 10 on its surface cause the rectangular block 8 inserted therein to rotate counterclockwise. The rectangular block 8 then drives the third rotating shaft 17, which is fixedly connected to it, to rotate. The rotation of the third rotating shaft 17 is transmitted through the first synchronous wheel 18, the first synchronous belt 19, and the first synchronous wheel 18 fixedly sleeved outside the first rotating shaft 6, ultimately driving the first rotating shaft 6 to rotate counterclockwise. The cover plate 7 fixedly sleeved outside the first rotating shaft 6 then flips upward and opens, exposing the display screen 2 for staff to read data.

[0039] When the staff completes the inspection and releases handle 3, the reset spring 27 releases its elastic potential energy to push the guide rod 25 and the arc plate 24 to reset outward. At the same time, the torsion spring 29 sleeved on the outside of the second rotating shaft 9 releases its elastic potential energy, causing the second rotating shaft 9 to rotate clockwise to reset. The above transmission path is transmitted in reverse, causing the cover plate 7 to automatically fall and close, covering the outside of the display screen 2 again to achieve protection. Throughout the process, the mounting plate 4 is detachably connected to the second groove 10 on the second rotating shaft 9 through the rectangular block 8, which is convenient for maintenance and replacement.
