Description

Technical Field

[0001] The utility model relates to the field of temperature sensors, in particular to an oil-seepage-proof temperature sensor housing structure. Background Art

[0002] In hydraulic equipment, the temperature of the hydraulic oil can affect the performance of the hydraulic system and the operating efficiency of the equipment. For example, in the hydraulic system of large-scale construction machinery, when the oil temperature exceeds 80°C, the viscosity of the hydraulic oil may decrease, affecting the sealing and power transmission efficiency of the system. Temperature sensors can detect abnormal oil temperatures in a timely manner.

[0003] In order to detect the temperature of the hydraulic oil, it is necessary to use a temperature sensor installed on the hydraulic equipment to detect the temperature of the hydraulic oil. The pressure inside the hydraulic equipment is relatively high. In addition, the hydraulic equipment will vibrate when it is running. Continuous vibration will cause the temperature sensor on the hydraulic equipment to become loose easily. If the connection between the hydraulic equipment and the temperature sensor is not tight, oil leakage is likely to occur. Utility Model Content

[0006] Preferably, the hydraulic equipment mounting seat and the positioning cylinder are fixedly connected by multiple groups of equally spaced reinforcement blocks, and the cross-section of the reinforcement blocks is a right-angled trapezoidal setting. At the same time, a threaded structure is opened inside the positioning cylinder, and the positioning cylinder is cylindrical.

[0007] Preferably, the force-bearing seat is a regular hexagonal structure made of metal material, and the surface of the force-bearing seat is evenly covered with three groups of lower pressure seats, and the distance between two adjacent groups of lower pressure seats is consistent.

[0008] Preferably, a guide seat is fixedly installed at one end of the drive plate away from the lower pressure seat, and the guide seat and the drive plate are both circular. At the same time, a through hole is opened inside the drive plate, and the diameter of the through hole is larger than the diameter of the stud, and a fixing nut is screwed on the outside of the stud.

[0020] As can be seen from the above, when in use, the temperature sensor housing 3 is held in the hand, and the detection end at the bottom of the temperature sensor housing 3 is inserted into the interior of the positioning cylinder 2 opened at the bottom of the hydraulic equipment mounting seat 1, and is screwed and fixed to the interior of the positioning cylinder 2. At this time, the force-bearing seat 4 on the temperature sensor housing 3 covers the surface of the hydraulic equipment mounting seat 1, and compresses the sealing gasket 5. The gap between the hydraulic equipment mounting seat 1 and the temperature sensor housing 3 is sealed through the sealing gasket 5. At the same time, the fixing nut 67 is tightened, and the fixing nut 67 is screwed to the outer side of the stud 68. At this time, the lower side of the end of the lower pressure seat 66 covers the upper side of the force-bearing seat 4. The three groups of lower pressure seats 66 evenly cover the top surface of the force-bearing seat 4 and press down the force-bearing seat 4 to avoid excessive pressure inside the hydraulic equipment mounting seat 1, which impacts the temperature sensor housing 3 and causes the temperature sensor housing 3 to loosen and leak oil.

[0021] As a preferred embodiment, the hydraulic equipment mounting base 1 and the positioning cylinder 2 are fixedly connected by multiple groups of equally spaced reinforcement blocks, and the cross-section of the reinforcement blocks is a right-angled trapezoid. At the same time, a threaded structure is opened inside the positioning cylinder 2, and the positioning cylinder 2 is cylindrical.

[0022] As a preferred embodiment, the force-bearing seat 4 is a regular hexagonal structure made of metal material, and the surface of the force-bearing seat 4 is evenly covered with three groups of lower pressure seats 66, while the distance between two adjacent groups of lower pressure seats 66 is consistent.

[0023] As a preferred embodiment, a guide seat 64 is fixedly installed on one end of the driving plate 65 away from the lower pressure seat 66, and the guide seat 64 and the driving plate 65 are both circular. At the same time, a through hole is opened inside the driving plate 65, and the diameter of the through hole is larger than the diameter of the stud 68. A fixing nut 67 is screwed on the outer side of the stud 68.

[0024] As a preferred embodiment, a guide hole is provided inside the guide seat 64 , and the guide hole is adapted to the size of the guide rod 63 , and the guide rod 63 is inserted into the guide hole provided inside the guide seat 64 .

[0025] As can be seen from the above, during use, the hydraulic equipment mounting base 1 will vibrate during operation, and continuous vibration will cause the temperature sensor housing 3 to become loose on the hydraulic equipment mounting base 1. At this time, tighten the fixing nut 67, and the fixing nut 67 presses down to press the drive plate 65, so that the pressing seat 66 can press down. The three groups of pressing seats 66 can evenly press down the three parts of the upper surface of the force-bearing seat 4, avoiding the continuous vibration that will cause the temperature sensor housing 3 to become loose on the hydraulic equipment mounting base 1, resulting in oil leakage.

At this time, the force-bearing seat 4 on the temperature sensor housing 3 covers the surface of the hydraulic equipment mounting seat 1, and compresses the sealing gasket 5. Through the sealing gasket 5, the gap between the hydraulic equipment mounting seat 1 and the temperature sensor housing 3 is sealed. At the same time, tighten the fixing nut 67, and the fixing nut 67 is screwed to the outside of the stud 68. At this time, the lower side of the end of the lower pressure seat 66 covers the upper side of the force-bearing seat 4, and the three groups of lower pressure seats 66 evenly cover the top surface of the force-bearing seat 4. The force-bearing seat 4 is also pressed down to avoid excessive pressure inside the hydraulic equipment mounting seat 1, which may impact the temperature sensor housing 3, causing the temperature sensor housing 3 to loosen and oil leakage to occur. The hydraulic equipment mounting seat 1 will vibrate during operation, and continuous vibration will cause the temperature sensor housing 3 to easily loosen on the hydraulic equipment mounting seat 1. At this time, tighten the fixing nut 67, and the fixing nut 67 presses down to press the drive plate 65, so that the pressing seat 66 can press down. The three groups of pressing seats 66 can evenly press down the three parts of the upper surface of the force-bearing seat 4 to avoid continuous vibration that may cause the temperature sensor housing 3 to easily loosen on the hydraulic equipment mounting seat 1, causing oil leakage to occur.
