Description

Technical Field

[0001] This utility model relates to the field of pressure gauge technology, specifically to a mechanical pointer pressure gauge. Background Technology

[0002] Mechanical pointer pressure gauges are commonly used pressure measurement tools in industrial settings, and their display clarity and environmental adaptability are key factors affecting the user experience.

[0003] In existing technologies, pressure gauges often employ an open design for their display areas, with the panel directly exposed and susceptible to dust, oil, or scratches, leading to blurred scales and obstructed pointers. Simultaneously, uneven light scattering on the panel surface is a significant issue, frequently resulting in localized areas of strong light or darkness. This is particularly problematic in low-light environments (such as at night or in workshop corners), making readings difficult and severely impacting operators' accurate assessment of pressure values. Existing products often employ supplementary lighting solutions by placing an independent light source on the back of the panel; however, the fixed position and unidirectional scattering of the light source make it difficult to evenly cover the entire display area, resulting in limited supplementary lighting effects. Furthermore, poor coordination between the light source and the diffusion structure can easily lead to glare caused by light reflection or focusing, further interfering with readings.

[0004] Therefore, it is necessary to propose a mechanical pointer pressure gauge. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a mechanical pointer pressure gauge, which has the advantages of good supplementary lighting and good dustproof effect, and overcomes the defects of the prior art mentioned in the background art.

[0006] This utility model provides the following technical solution: a mechanical pointer pressure gauge, comprising a housing, a chip, a movement, a diffuser plate, and a panel. The chip, movement, diffuser plate, and panel are all installed inside the housing. The chip is connected to the movement. The diffuser plate is disposed on the side of the movement away from the chip. The panel is located on the side of the diffuser film. Both sides of the diffuser plate are provided with the diffuser film. The surface of the panel is provided with transparent scale marks. The output end of the movement is fixedly connected to a rotating shaft. The rotating shaft passes through the diffuser plate and the panel in sequence. The end of the rotating shaft is fixedly connected to a pointer, which is located on the surface of the panel.

[0007] Preferably, the diffuser plate has grooves on both sides, and LED lights are installed inside the grooves.

[0008] Preferably, the surface of the panel has a threaded hole, and a bolt is threaded into the inside of the threaded hole, with the end of the bolt threadedly connected to the diffuser plate.

[0009] Preferably, a transparent acrylic sheet is fixedly installed at one end of the housing, and the transparent acrylic sheet covers the surface of the panel.

[0010] Preferably, a power socket is provided on the surface of the chip.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This mechanical pointer pressure gauge features a modular and compact layout, integrating the chip, movement, diffuser plate, and panel into a single housing. This design facilitates assembly and maintenance while ensuring efficient transmission and conversion of pressure signals through direct connection between the chip and movement. The diffuser film on both sides of the diffuser plate evenly scatters light, preventing localized strong light or dark areas. Combined with LEDs installed in the grooves along the sides, it provides supplementary lighting in low-light environments, further enhancing the uniformity and clarity of the panel display. Threaded holes and bolts on the panel surface securely fasten the diffuser plate to the panel, preventing shifting or loosening due to vibration or impact, while retaining a removable feature for maintenance. A transparent acrylic plate fixed to one end of the housing covers the panel, protecting the transparent scale and pointer from dust, liquid, or scratches without obstructing light transmission, ensuring clear readings.

[0025] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4 As shown, a mechanical pointer pressure gauge includes a housing 100, a chip 200, a movement 300, a diffuser plate 400, and a panel 500. The chip 200, movement 300, diffuser plate 400, and panel 500 are all installed inside the housing 100. The chip 200 is connected to the movement 300. The diffuser plate 400 is located on the side of the movement 300 away from the chip 200. The panel 500 is located on one side of the diffuser film 405. Both sides of the diffuser plate 400 are provided with the diffuser film 405. The surface of the panel 500 is provided with transparent scale marks 501. The output end of the movement 300 is fixedly connected to a rotating shaft 401. The rotating shaft 401 passes through the diffuser plate 400 and the panel 500 in sequence. The end of the rotating shaft 401 is fixedly connected to a pointer 402, which is located on the surface of the panel 500. By integrating the chip 200, mechanism 300, diffuser plate 400, and panel 500 inside the housing 100, a modular and compact layout is formed, which facilitates assembly and maintenance. The direct connection between the chip 200 and the mechanism 300 ensures efficient transmission and conversion of pressure signals. The diffuser film 405 on both sides of the diffuser plate 400 can uniformly scatter light, avoid local strong light or dark areas, and improve the uniformity and clarity of the display on the panel 500. The rotating shaft 401 passes through the diffuser plate 400 and the panel 500 and is fixedly connected to the pointer 402, realizing synchronous linkage between the output end of the mechanism 300 and the display end, ensuring the accuracy of pressure indication.

[0027] Preferably, grooves 403 are provided on both sides of the diffuser plate 400, and LED lights 404 are installed inside the grooves 403. The grooves 403 on both sides of the diffuser plate 400 provide precise installation and positioning space for the LED lights 404, allowing the LED lights 404 to be stably attached to the edge of the diffuser plate 400. The LED lights 404 can provide auxiliary lighting for the diffuser film 405 and the panel 500 when the ambient light is low. Combined with the scattering effect of the diffuser film 405, the visibility of the pressure gauge reading in low-light scenes is further enhanced. The structural design of the grooves 403 also facilitates the later maintenance or replacement of the LED lights 404.

[0028] Preferably, the surface of the panel 500 has a threaded hole 502, and a bolt 503 is threaded into the inside of the threaded hole 502. The end of the bolt 503 is threadedly connected to the diffuser plate 400. The engagement of the threaded hole 502 and the bolt 503 on the surface of the panel 500 allows the diffuser plate 400 and the panel 500 to be fastened together by threads, effectively preventing the diffuser plate 400 from shifting or loosening due to external vibration or accidental collision. This detachable threaded connection method not only ensures the stability of the structure but also facilitates the separate disassembly of the diffuser plate 400 or the panel 500 during maintenance, reducing maintenance difficulty.

[0029] Preferably, a transparent acrylic plate 101 is fixedly installed at one end of the housing 100, and the transparent acrylic plate 101 covers the surface of the panel 500. The transparent acrylic plate 101 fixed at one end of the housing 100 covers the surface of the panel 500, which can provide physical protection for the transparent scale marks 501 and pointers 402 on the panel 500, avoiding contamination or damage to the display area by dust, liquid or minor scratches; the transparent material design does not obstruct the transmission of light, ensuring clear observation of the pressure gauge reading, while extending the actual service life of the panel 500.

[0030] Preferably, a power socket 600 is provided on the surface of the chip 200 to facilitate connection of the chip 200 to a power source.
