Description

Technical Field

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

[0002] Pressure gauges are commonly used measuring instruments in industrial production, fluid systems, and equipment. In industries such as petrochemicals, power generation, and machinery manufacturing, pressure gauges are used to monitor the fluid pressure in pipelines, containers, boilers, and other equipment in real time. By observing the pressure gauge readings, operators can determine whether the equipment is operating normally and whether there are any pressure anomalies.

[0003] However, pressure gauges often face various risks during actual use, such as external collisions and impacts from splashing objects, so protective mechanisms are needed to protect them.

[0004] Existing pressure gauges are protected by their own casing or a single protective sleeve. This protection is relatively basic, and the casing is prone to cracking and leaking or internal components may be damaged when the pressure gauge is subjected to impacts or splashes. This can reduce the lifespan of the pressure gauge and consequently affect the readings and normal operation of the gauge. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision alloy chip resistor to address the problem that the aforementioned technology offers relatively simple protection, making it susceptible to casing breakage and leakage or internal component damage when the pressure gauge is subjected to impacts or splashes. This reduces the lifespan of the pressure gauge and consequently affects its readings and normal operation.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A pressure gauge protection structure includes a housing, a dial mounted on one end of the housing, a pointer mounted inside the dial, a mounting base fixed to the lower end of the housing, a mounting rod fixed to the lower end of the mounting base, and a threaded rod. A first protective plate is provided at one end of the housing, and a second protective plate is provided at the end of the housing away from the first protective plate, the second protective plate corresponding to the dial. A protective mechanism is provided between the first and second protective plates to improve the protection effect on the pressure gauge and absorb and weaken the impact on the pressure gauge.

[0008] As a further embodiment of this utility model: the protective mechanism includes two symmetrical limiting telescopic rods fixed on both sides of the mounting base, wherein the telescopic ends of two of the limiting telescopic rods are fixedly connected to the first protective plate, and the other two limiting telescopic rods are fixedly connected to the second protective plate. A protective frame is provided on the side of the housing, the protective frame is located between the first protective plate and the second protective plate, and a protective component is provided between the protective frame and the first protective plate. Through the protective component, the impact force is absorbed, reducing the impact force on the pressure gauge.

[0009] As a further embodiment of this utility model: the protective component includes a damper disposed between the first protective plate and the second protective plate. The dampers are arranged in an array and are located inside the protective frame. Two symmetrical fixing rings are fixed on the damper. A spring is sleeved on the damper, and the ends of the springs are fixedly connected to the two fixing rings. A protective component is provided between the protective frame and the housing. Through the protective component, the impact force on the pressure gauge is further reduced, thereby improving the protection effect on the pressure gauge.

[0010] As a further embodiment of this utility model: the protective component includes fixing blocks fixed on both sides of the mounting base, the fixing blocks being fixedly connected to the protective frame, and connecting blocks being fixedly fixed on both the first protective plate and the second protective plate, the connecting blocks being fixedly connected to the damper.

[0011] As a further embodiment of this utility model: the protective frame is an arc-shaped spring sheet, and the connecting block and the fixing block are uniformly rubber shock-absorbing blocks.

[0012] As a further embodiment of this utility model: the second protective plate is a transparent acrylic plate.

[0013] As a further embodiment of this utility model: a pad is fixed on both ends of the housing, the pad is annular and is an elastic rubber pad.

[0014] As a further embodiment of this utility model: heat-conducting plates are fixed inside both sides of the housing and arranged in an array. The heat-conducting plates extend into the housing and are fixedly connected to a heat dissipation plate extending out of the housing. Heat dissipation fins are fixed on the heat dissipation plate and arranged in an array.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model, through the protective mechanism in conjunction with protective plate one and protective plate two, absorbs and transmits the impact force when subjected to impact through dampers and springs, thereby improving the protective effect. Furthermore, the protective frame is an arc-shaped spring sheet, which further enhances the protective effect on the shell, reduces the frontal impact force on the pressure gauge, minimizes damage to internal components and the outer shell, and facilitates the use of the pressure gauge.

[0017] 2. In this utility model, the frame is an arc-shaped spring sheet that deforms when subjected to impact. Then, the connecting block and the fixing block are rubber shock absorbers that weaken the force transmitted between the damper and the protective frame before it is transmitted into the mounting base. The pad is a ring-shaped elastic rubber pad. When the first and second protective plates move and come into contact with the pad, the pad deforms, reducing the impact force on the pressure gauge, reducing the possibility of cracks in the pressure gauge housing and damage to internal components, and improving the protection effect of the pressure gauge.

Detailed Implementation

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-3As shown, this utility model is a pressure gauge protection structure, including a housing 1, a dial 2 installed at one end of the housing 1, a pointer 7 installed inside the dial 2, a mounting base 3 fixed at the lower end of the housing 1, a mounting rod 4 fixed at the lower end of the mounting base 3, and a threaded rod 4. A protective plate 5 is provided at one end of the housing 1, and a protective plate 6 is provided at the end of the housing 1 away from the protective plate 5. The protective plate 6 corresponds to the dial 2. A protective mechanism is provided between the protective plate 5 and the protective plate 6. The protective mechanism is used to improve the protection effect of the pressure gauge and absorb and weaken the impact on the pressure gauge.

[0026] Specifically, the housing 1 is installed on the pipeline to be tested, and the housing 1 is fixed by the mounting rod 4. During use, the pressure gauge is protected by the first protective plate 5 and the second protective plate 6. The value is then viewed through the dial 2 and the pointer 7. The protective plate 5 and the second protective plate 6 work together to improve the protection effect on the pressure gauge, reduce the impact force on the pressure gauge, and reduce the impact on the service life of the pressure gauge and the test value.

[0027] In this embodiment, refer to Figure 2 - Figure 4 As shown, the protective mechanism includes two symmetrical limiting telescopic rods 18 fixed on both sides of the mounting base 3. The telescopic ends of the two limiting telescopic rods 18 are fixedly connected to the first protective plate 5, and the other two limiting telescopic rods 18 are fixedly connected to the second protective plate 6. A protective frame 16 is provided on the side of the housing 1, located between the first protective plate 5 and the second protective plate 6. A protective component is provided between the protective frame 16 and the first protective plate 5. The protective component absorbs the impact force and reduces the impact force on the pressure gauge. The protective component includes a damper 8 disposed between the first protective plate 5 and the second protective plate 6. The dampers 8 are arranged in an array and are located inside the protective frame 16. Two symmetrical fixing rings 9 are fixed on the dampers 8, and springs 10 are sleeved on the dampers 8. The ends of the springs 10 are fixedly connected to the two fixing rings 9. A protective element is provided between the protective frame 16 and the housing 1. The protective element further weakens the impact force on the pressure gauge and improves the protection effect on the pressure gauge. The protective components include fixing blocks 11 fixed to both sides of the mounting base 3, which are fixedly connected to the protective frame 16. Connecting blocks 12 are fixed to both the first protective plate 5 and the second protective plate 6, and these connecting blocks 12 are fixedly connected to the damper 8. The protective frame 16 is an arc-shaped spring sheet, and the connecting blocks 12 and fixing blocks 11 are uniformly fitted with rubber shock-absorbing blocks. The second protective plate 6 is a transparent acrylic sheet. Pads 17 are fixed to both ends of the housing 1; these pads 17 are annular and are elastic rubber pads.

[0028] Specifically, when the pressure gauge is impacted by a foreign object or splashing material, the protective plate 5 and the protective plate 6 move under the impact force, causing the limiting telescopic rod 18 to extend and retract. Then, the protective plate 5 drives the damper 8 to extend and retract, absorbing and weakening the impact. At the same time, the spring 10 extends and retracts, further weakening the impact force. Meanwhile, the protective frame 16 protects the side of the housing 1. The force on the protective plate 5 and the protective plate 6 is transmitted to the mounting base 3 through the limiting telescopic rod 18. Then, the force on the protective frame 16 is transmitted to the mounting base 3 through the fixing block 11, reducing the frontal impact force on the pressure gauge, reducing the impact force, improving the protection effect of the pressure gauge, and reducing the damage to internal components and the housing.

[0029] Specifically, the frame is an arc-shaped spring sheet that deforms when subjected to impact. Then, the connecting block 12 and the fixing block 11 are rubber shock-absorbing plates, which weaken the force transmitted between the damper 8 and the protective frame 16 before transmitting it into the mounting base 3. This reduces the impact force on the pressure gauge, reduces the possibility of cracks in the pressure gauge housing 1 and damage to internal components, and improves the protection effect of the pressure gauge. The second protective plate 6 is a transparent acrylic plate, which makes it easy for staff to observe the pressure gauge value. The pad 17 is an annular elastic rubber pad. When the first protective plate 5 and the second protective plate 6 move and come into contact with the pad 17, the pad 17 deforms, further improving the protection effect of the pressure gauge.

[0030] In this embodiment, refer to Figure 3 - Figure 4 As shown, heat-conducting plates 13 are fixed inside both sides of the housing 1 and are arranged in an array. The heat-conducting plates 13 extend into the housing 1 and are fixedly connected to heat dissipation plates 14 extending out of the housing 1. Heat dissipation fins 15 are fixed on the heat dissipation plates 14 and are arranged in an array.

[0031] Specifically, when working in a high-temperature environment, the heat-conducting plate 13 conducts heat out of the housing 1 and transfers it to the heat dissipation plate 14, increasing the contact area with the air and improving the heat dissipation effect. Then, through multiple heat dissipation fins 15, the contact area with the air is further increased, improving the heat dissipation effect and reducing the impact on the pressure gauge performance.

[0032] The working principle of this utility model is as follows: the housing 1 is installed on the pipe to be tested, and the housing 1 is fixed by the mounting rod 4. When in use, the pressure gauge is protected by the first protective plate 5 and the second protective plate 6. The value is then viewed by the dial 2 and the pointer 7.

[0033] When the pressure gauge is impacted by a foreign object or splashing material, the first protective plate 5 and the second protective plate 6 move under the impact force, causing the limiting telescopic rod 18 to extend and retract. Then, the first protective plate 5 drives the damper 8 to extend and retract, absorbing and weakening the impact. At the same time, the spring 10 extends and retracts, further weakening the impact force. Meanwhile, the protective frame 16 protects the side of the housing 1. The force on the first protective plate 5 and the second protective plate 6 is transmitted to the mounting base 3 through the limiting telescopic rod 18. Then, the force on the protective frame 16 is transmitted to the mounting base 3 through the fixing block 11, reducing the frontal impact force on the pressure gauge.

[0034] The frame is an arc-shaped spring sheet, which deforms when subjected to impact. Then, the connecting block 12 and the fixing block 11 are rubber shock absorbers, which weaken the force transmitted between the damper 8 and the protective frame 16, and then transmit it into the mounting base 3. The second protective plate 6 is a transparent acrylic plate, which makes it easy for the staff to observe the pressure gauge value. The pad 17 is an annular elastic rubber pad. When the first protective plate 5 and the second protective plate 6 move and come into contact with the pad 17, the pad 17 deforms.

[0035] When working in a high-temperature environment, the heat conduction plate 13 conducts heat out of the shell 1 and transfers it to the heat dissipation plate 14, increasing the contact area with the air and improving the heat dissipation effect. Then, through multiple heat dissipation fins 15, the contact area with the air is further increased, improving the heat dissipation effect and reducing the impact on the pressure gauge performance.

[0036] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
