Description

Technical Field

[0001] The utility model relates to the technical field of thermocouples, in particular to a compression spring fixed type thermocouple. Background Technique

[0002] A thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures the temperature, converts the temperature signal into a thermoelectromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument. However, if the surface of the measured object cannot be drilled, the thermocouple cannot extend into the material to measure the temperature, and the accuracy of the measured value is relatively low.

[0003] In the prior art, CN218973662U discloses a compression spring fixed type thermocouple, including a temperature measuring frame and a thermocouple main body. Convenient fixing mechanisms are arranged on the front and back of the temperature measuring frame, and a non-contact temperature measuring mechanism is arranged in the inner cavity of the temperature measuring frame. The convenient fixing mechanism includes a reference cylinder, the reference cylinder is fixedly installed on the front and back of the temperature measuring frame, and a sliding part is detachably connected in the inner cavity of the reference cylinder. Through the elastic force of the elastic part, the graphene sheet can be closely attached to the outer wall of the measured object, so as to absorb the temperature of the measured object, and then quickly transfer it to the inner cavity of the temperature measuring frame through the conical heat dissipation block. Through the design of the circulating fan, the air in the inner cavity of the temperature measuring frame can be driven to circulate quickly, so that the thermocouple main body realizes the function of non-contact temperature measurement, improves the accuracy of temperature measurement, and prolongs the service life of the thermocouple main body.

[0004] The existing device adjusts the position of the clamping block according to the actual size of the measured object, and then locks this structure on the outer wall of the measured object through the elastic force of the fixed compression spring. However, the existing device can only be adjusted according to the size of the object, and the height of the clamping points is the same. When the clamping points corresponding to the outer wall of the measured object cannot be clamped due to the inclined surface, the position of the clamping and fixing points of the existing device cannot be adjusted according to the shape of the measured object, thus reducing the practicability of the device.

The connecting rod 106 is fixedly connected to the sliding cylinder 105 and is located on one side of the sliding cylinder 105. The clamping frame 107 is arranged on the connecting rod 106 and is located on one side of the connecting rod 106. The support frame 108 is fixedly connected to the fixing frame 104 and is located on one side of the support frame 108. The locking seat 109 is fixedly connected to the support frame 108 and is located on one side of the support frame 108. The screw rod 110 is threadedly connected to the locking seat 109 and is located on one side of the locking seat 109. The rotating head 111 is fixedly connected to the screw rod 110 and is located on one side of the screw rod 110. The abutting plate 112 is connected to the locking seat 109 through the return spring and is located on the side of the locking seat 109 close to the sliding cylinder 105. The return spring is arranged on the locking seat 109 and is connected to the abutting plate 112. There are two fixing frames 104, and the two fixing frames 104 are welded on the left and right sides of the temperature measuring frame 101. There is a chute in the fixing frame 104. There are two sliding cylinders 105, and the two sliding cylinders 105 are slidably connected in the chutes of the corresponding two fixing frames 104. The sliding cylinder 105 is cylindrical and can move left and right in the fixing frame 104 and can also rotate. There are two connecting rods 106, and the two connecting rods 106 are welded on the corresponding two sliding cylinders 105.

The surfaces of the measured object can be abutted by the two clamping frames 107 to form clamping. There are four support frames 108, and the four support frames 108 are welded on the corresponding two fixing frames 104.

The return spring is arranged on the locking seat 109 and connected to the abutting plate 112. Through the return spring, the movement of the abutting plate 112 can be connected and supported and rebounded and reset. Thus, when the sliding cylinder 105 can move left and right and rotate in the fixed frame 104, the operator can adjust the clamping position of the clamping frame 107 connected to the connecting rod 106 on the sliding cylinder 105.

Through the movement of the abutting plate 112, the rubber can be driven to move downward and abut against the sliding cylinder 105, thereby locking the movement or rotation of the sliding cylinder 105. Thus, under the action of the rotation or movement of the sliding cylinder 105 in the fixed frame 104, the clamping position of the clamping frame 107 can be adjusted according to the shape of the object to be measured, thereby improving the practicability of the device.

[0025] Secondly, both ends of the spring body 116 are connected to the locking seat 109 and the abutting plate 112 respectively through the fixing member.

Both ends of the four spring bodies 116 are connected to the locking seat 109 and the abutting plate 112 respectively through the fixing member. Through the spring body 116, the movement of the abutting plate 112 can be connected and supported. At the same time, through the deformation and reset ability of the spring body 116, the moved abutting plate 112 can be driven to rebound and reset. The fixing member is arranged on the locking seat 109 and the abutting plate 112 and connected to the spring body 116. Through the fixing member, both ends of the spring body 116 can be connected and fixed to the corresponding two locking seats 109 and abutting plates 112.

[0026] Meanwhile, the first fixing base 117 is fixedly connected to the locking base 109 and the spring body 116 respectively.

[0027] Finally, the limiting cylinder 114 is fixedly connected to the abutting plate 112 and is located on one side of the abutting plate 112. The limiting rod 115 is slidably connected to the limiting cylinder 114, is fixedly connected to the abutting plate 112, and is located on the side of the limiting cylinder 114 close to the abutting plate 112. There are four limiting cylinders 114, and the four limiting cylinders 114 are welded to the corresponding two locking bases 109.

Through the limiting cylinder 114, the sliding of the limiting rod 115 can be connected, supported and directionally limited. The four limiting rods 115 are welded to the corresponding two abutting plates 112. Through the movement of the limiting rod 115, the movement of the abutting plate 112 can be directionally limited, so that when the abutting plate 112 drives the rubber pad 113 to abut against the sliding cylinder 105, it is more stable.

[0028] When using a compression spring fixed type thermocouple of this embodiment, under the action that the sliding cylinder 105 can move left and right and can also rotate within the fixed frame 104, an operator can adjust the clamping position of the clamp 107 connected to the connecting rod 106 on the sliding cylinder 105. After the clamp 107 moves to the corresponding clamping position, by rotating the rotating head 111 by the operator, the screw 110 can move downward at the other end under the cooperation of the threaded hole of the locking seat 109 and abut and push the abutting plate 112 to move downward. Through the movement of the abutting plate 112, the rubber can be driven to move downward and abut against the sliding cylinder 105, thereby locking the movement or rotation of the sliding cylinder 105. Thus, under the action of the rotation or movement of the sliding cylinder 105 within the fixed frame 104, the clamping position of the clamp 107 can be adjusted according to the shape of the object to be measured, thereby improving the practicability of the device.
