TECHNICAL FIELD
[0001] The utility model relates to the thermal resistance technical field, specifically, a kind of high wear resistance shock resistance thermal resistance. BACKGROUND
[0002] Thermal resistance is the most commonly used temperature detector in medium-low temperature area. Thermal resistance temperature measurement is based on the characteristic that the resistance value of metal conductor increases with temperature increase. Its main feature is high measurement accuracy and stable performance. The measurement accuracy of platinum thermal resistance is the highest, which is not only widely used in industrial temperature measurement, but also made into standard reference instrument. Thermal resistance is mostly made of pure metal materials, and the most commonly used is platinum and copper. In addition, nickel, manganese and rhodium materials have been used to manufacture thermal resistance. There are many types of temperature sensing materials commonly used in metal thermal resistance, and platinum wire is the most commonly used. In addition to platinum wire, copper, nickel, iron and iron-nickel are also used as metal thermal resistance materials for industrial measurement. The temperature measurement principle of thermal resistance is based on the characteristic that the resistance value of conductor or semiconductor changes with temperature change. Thermal resistance usually transmits resistance signal to computer control device or other secondary instrument through lead.
[0003] Thermal resistance is usually installed on equipment for use. In order to prevent the equipment from shaking during use and affecting the normal work of thermal resistance, a damping structure is usually added to the thermal resistance. Damping springs are used in the damping structure to rely on repeated deformation of the damping springs to achieve buffering effect. Single damping spring can only cope with slight shaking. When encountering severe shaking, the up and down amplitude of the spring is too large, which will also cause damage to the thermal resistance. In view of this, we propose a device with multiple stages of shock absorption and capable of limiting the thermal resistance, namely a high wear resistance shock resistance thermal resistance.

[0022] Thermistor is the most commonly used temperature detector in medium and low temperature zone. Thermistor temperature measurement is based on the characteristic that the resistance value of metal conductor increases with the increase of temperature to measure temperature. Its main feature is high measurement accuracy and stable performance. The measurement accuracy of platinum thermistor is the highest, which is not only widely used in industrial temperature measurement, but also made into standard reference instrument. Thermistor is mostly made of pure metal material, and the most used is platinum and copper. In addition, nickel, manganese and rhodium materials have begun to be used to manufacture thermistor. The commonly used temperature sensing materials of metal thermistor are various, and the most commonly used is platinum wire. In addition to platinum wire, the metal thermistor materials used for industrial measurement also include copper, nickel, iron, iron-nickel, etc. The temperature measurement principle of thermistor is based on the characteristic that the resistance value of conductor or semiconductor changes with temperature to measure temperature and parameters related to temperature. Thermistor usually needs to transmit resistance signal to computer control device or other secondary instrument through lead. Please refer to Figures 1-4 As shown in the figure, the utility model provides a kind of high wear resistance shock resistance thermistor, including base 1, the top of base 1 is fixedly connected with multiple telescopic rods 11, the other end of telescopic rod 11 is fixedly connected with the bottom of fixed plate 2, the top of base 1 is fixedly connected with multiple spring one 12, the other end of spring one 12 is fixedly connected with the bottom of fixed plate 2, spring one 12 is sleeved on the outer surface of telescopic rod 11, the top center of base 1 is slidably connected with pressing plate 3, the front end of pressing plate 3 is fixedly connected with pull rod 31, the top end of pull rod 31 is fixedly connected with baffle 32, baffle 32 is located above the side of fixed plate 2, air bag 33 is placed on the upper surface of pressing plate 3, the top of air bag 33 does not contact with the bottom of fixed plate 2.
[0023] And the improvement of the utility model lies in:
[0024] Since the thermal resistance is generally installed on the equipment for use, in order to prevent the equipment from shaking during use and affecting the normal work of the thermal resistance, a damping structure is generally added to the thermal resistance, and a damping spring is used in the damping structure, which relies on repeated deformation of the damping spring to play a buffering effect. A single damping spring can only cope with slight shaking, and when encountering severe shaking, the up and down amplitude of the spring is too large and can also cause damage to the thermal resistance. Therefore, when the equipment shakes, the telescopic rod 11 and the spring 12 below the fixed plate 2 will perform a first level of damping on the thermal resistance on the fixed plate 2, and when the shaking is severe, the fixed plate 2 will continue to compress the telescopic rod 11 and the spring 12, until it contacts the air bag 33, thereby performing a second level of damping on the thermal resistance. The air bag 33 is compressed downward by the pressure, which pushes the pressing plate 3 to move downward, thereby driving the baffle 32 to limit and fix the side of the fixed plate 2 above, thereby preventing damage to the thermal resistance due to the excessive amplitude of the spring 12.
[0025] In order to better fix the air bag 33, the outer sleeve of the air bag 33 is sleeved with a fixing ring 34, and the side surface of the fixing ring 34 is fixedly connected with a plurality of support frames 35. The other end of the support frame 35 is fixedly connected with the base 1. The fixing ring 34 is fixed by the plurality of support frames 35, which ensures that the air bag 33 is located directly above the pressing plate 3, so as to better exert pressure on the pressing plate 3.
[0026] In order to provide sufficient support force for the pressing plate 3, considering the gravity of the air bag 33 itself, a recess 13 is formed in the top center of the base 1, and the size of the recess 13 corresponds to the size of the pressing plate 3. The bottom inner surface of the recess 13 is fixedly connected with a spring 14, and the other end of the spring 14 is fixedly connected with the bottom of the pressing plate 3. Under the action of the support force of the spring 14, the pressing plate 3 protrudes above the upper surface of the base 1 and contacts the air bag 33, thereby providing space for the downward movement of the pressing plate 3, and ensuring the normal work of the limiting device.
[0027] In order to better limit and fix the fixed plate 2, the front end of the base 1 is fixedly connected with a support plate 15, and a plurality of clamping grooves 16 are formed in the top center of the support plate 15. The clamping grooves 16 correspond to the inclined surface of the baffle 32, and the clamping grooves 16 are also inclined surfaces. When the baffle 32 moves downward, the baffle 32 moves along the inclined surface of the clamping groove 16 to the next clamping groove 16, thereby fixing the baffle 32 and limiting the fixed plate 2.
[0028] In view of the different sizes and shapes of the thermal resistance, in order to adapt to more types of thermal resistance, the inside of the fixed plate 2 is slidably connected with a clamping plate 21, both ends of the clamping plate 21 are fixedly connected with a push rod 22, the other end of the push rod 22 is fixedly connected with a horizontal plate 25, the push rod 22 penetrates through the side edge of the fixed plate 2, by pushing the horizontal plate 25 forward and backward, the push rod 22 pushes the clamping plate 21, the sliding of the clamping plate 21 in the fixed plate 2 is realized, and the size of the thermal resistance is adjusted.
[0029] In order to better fix the thermal resistance, the side edge of the fixed plate 2 is rotatably connected with a nut 23, the other end of the nut 23 is fixedly connected with a rotating disc 24, the nut 23 is rotatably connected with the horizontal plate 25, by rotating the rotating disc 24, the nut 23 is rotated, thereby pushing the horizontal plate 25, the clamping plate 21 is driven to clamp and fix the thermal resistance.
[0030] In summary, the working principle of the scheme is as follows:
[0031] When the device works, the thermal resistance is placed on the fixed plate 2, by rotating the rotating disc 24, the nut 23 is rotated, thereby pushing the horizontal plate 25, the push rod 22 pushes the clamping plate 21, so that the clamping plate 21 clamps and fixes the thermal resistance, when the device shakes, the telescopic rod 11 and the spring one 12 below the fixed plate 2 will perform a first level of shock absorption on the thermal resistance on the fixed plate 2, when the shaking is severe, the fixed plate 2 will continue to compress the telescopic rod 11 and the spring one 12 downward, until the air bag 33 is contacted, thereby performing a second level of shock absorption on the thermal resistance, the air bag 33 is compressed downward under the pressure, the pressing plate 3 is pushed downward, the spring two 14 is pressed by the pressing plate 3, a third level of shock absorption is realized, the pressing plate 3 drives the pull rod 31 to move downward, thereby driving the baffle 32 to move downward, the baffle 32 moves along the inclined surface of the clamping groove 16 to the next clamping groove 16, thereby fixing the baffle 32, limiting the fixed plate 2, thereby preventing the thermal resistance from being damaged due to the excessive amplitude of the spring one 12.
[0032] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments, the above embodiments and the description in the specification are only preferred examples of the utility model, and are not used to limit the utility model, various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
