Description
Technical Field
[0001] This utility model relates to the field of pressure gauges, and more specifically, to a shock-resistant pressure gauge. Background Technology
[0002] Shock-resistant pressure gauges are filled internally with an appropriate amount of damping fluid (such as silicone oil or glycerin). The main function of the damping fluid is to eliminate the influence of external vibrations on the pressure measurement value. When the external environment vibrates, the damping fluid can absorb and disperse this vibration energy, thereby ensuring the stability and accuracy of the pressure measurement value.
[0003] Traditional pressure gauges often feature simple, uniformly shaped, and relatively large casings (usually a cylindrical tube). This necessitates filling the internal damping fluid (such as silicone oil or glycerin) in large quantities, increasing overall production costs. Furthermore, the cylindrical casing makes it susceptible to bending and deformation during assembly, potentially damaging the gauge. This design also hinders efforts to increase casing strength while reducing costs. Therefore, inventing a shock-resistant pressure gauge to address these issues has become a pressing problem for those skilled in the art. Utility Model Content

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a shock-resistant pressure gauge, comprising...
[0025] The pressure gauge body 100 includes a cover body 110 and a housing body 120. The cover body 110 is locked to the outside of the housing body 120. A connector 130 is installed at the bottom of the housing body 120. The interior of the housing body 120 is filled with glycerin. The housing body 120 includes a tail ring plate 121 and an outer ring plate 122. An upper arc portion 1212 of the tail ring plate 121 and a lower arc portion of the outer ring plate 122 are provided between the tail ring plate 121 and the outer ring plate 122. 1221, the tail ring plate 121 and the outer ring plate 122 are smoothly connected by the upper arc portion 1212 of the tail ring and the lower arc portion 1221 of the outer ring. A sealing plug 126 is sealed and snapped onto one side of the tail ring plate 121 and the outer ring plate 122. The tail ring plate 121 is smaller than the outer ring plate 122, which effectively reduces the production cost and reduces the filling amount when filling the internal glycerin. At the same time, the arc transition of the tail ring plate 121 and the connection with the outer ring plate 122 increases the strength.
[0026] Other pressure gauge components are also installed inside the cover body 110 and the case body 120.
[0027] Please see Figure 3 and Figure 4 The watch cover body 110 includes a limiting ring 111, the middle part of the limiting ring 111 is hollow, and a glass cover plate 112 is provided inside the limiting ring 111. The watch cover body 110 is a normal watch cover.
[0028] An outer edge plate 123 is fixedly connected to the side of the outer ring plate 122 away from the tail ring plate 121. The outer edge plate 123 is bolted to the inner wall of the limiting ring 111. The outer edge plate 123 and the outer ring plate 122 are vertically connected. An upper arc portion 1222 of the outer ring is provided at the connection between the outer edge plate 123 and the outer ring plate 122. The arc directions on both sides of the upper arc portion 1222 are towards the inner outer side of the outer ring plate 122. A smooth and continuous transition is formed between the outer edge plate 123 and the outer ring plate 122, which helps to disperse external forces, allowing each layer to withstand a certain amount of pressure, thereby improving the stability of the overall structure and better resisting external pressure and deformation. The outer ring plate 122 has a diameter of 61-63mm, and the tail ring plate 121 has a diameter of 51-53mm. An inner back plate 124 is fixedly connected to the back of the tail ring plate 121. The connection between the inner back plate 124 and the tail ring plate 121 is provided with an upper arc portion 1241 and a lower arc portion 1211 of the tail ring. The upper arc portion 1241 and the lower arc portion 1211 of the tail ring form a smooth and continuous transition. The arc of the upper arc portion 1241 faces downward outside the inner back plate 124, and the arc of the lower arc portion 1211 faces upward outside the tail ring plate 121. The tail ring plate 121, outer ring plate 122, outer edge plate 123, inner back plate 124, and arc surface are all integrally cast, which reduces the risk of strength reduction due to weak connection, reduces the size of the tail ring plate 121, and facilitates the installation of internal components by changing the size of internal pressure connection and elastic element.
[0029] Both sides of the connection between the outer ring plate 122 and the tail ring plate 121 are arc-shaped, and there is a smooth and continuous transition between the tail ring plate 121 and the outer ring plate 122. A top mounting plate 125 extends outward from the top of the connection between the tail ring plate 121 and the outer ring plate 122. The top mounting plate 125 is rectangular, and each of its four sides has a connecting arc portion 1251. The connecting arc portion 1251 forms a smooth and continuous transition with the tail ring plate 121 and the outer ring plate 122, which helps to disperse external forces, allowing each layer to withstand a certain amount of pressure, thereby improving the stability of the overall structure.
[0030] A through hole is provided in the middle of the top mounting plate 125, and the sealing plug 126 is inserted into the through hole of the top mounting plate 125 for limiting and sealing. Guide legs 128 are connected in a ring at the bottom of the sealing plug 126. An annular groove is provided between the guide legs 128 and the sealing plug 126. The annular groove corresponds to and seals the through hole of the top mounting plate 125. Multiple guide legs 128 are evenly distributed, and the multiple guide legs 128 and the sealing plug 126 are arranged in a frustum shape. A top cover 127 is fixedly connected to the outside of the sealing plug 126. An arc-shaped protrusion is provided on the top of the top cover 127 to facilitate sealing the sealing plug 126 in the through hole of the top mounting plate 125.
[0031] Working principle: The tail ring plate 121 and the outer ring plate 122 are tightly connected to the lower arc portion 1211 of the tail ring via the upper arc portion 1241 of the back plate, forming a robust and stable watch case structure. The upper arc portion 1241 of the back plate and the lower arc portion 1211 of the tail ring plate 121 and the outer ring plate 122 reduce stress concentration, improving the strength and durability of the watch case. At the same time, the diameter of the outer ring plate 122 is 61-63mm, and the diameter of the tail ring plate 121 is 51-53mm. This size design ensures that the internal structure of the watch case... The installation of components further reduces the size of the watch case. The sealing plug 126 is inserted into the through hole of the top mounting plate 125 to ensure the sealing of the inside of the watch case. The bottom of the sealing plug 126 has guide legs 128 distributed in a ring. An annular groove is provided between the guide legs 128 and the sealing plug 126, which corresponds to the through hole of the top mounting plate 125 to seal, further improving the sealing performance. At the same time, the frustum-shaped arrangement of the guide legs 128 and the sealing plug 126 makes it easier to align and insert the sealing plug 126 during installation.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
