Description

Technical Field

[0001] This utility model belongs to the technical field of temperature transmitters, and in particular relates to an adjustable temperature transmitter. Background Technology

[0002] A temperature transmitter is a device used to measure temperature and convert it into a standard signal output. Its main function is to convert the temperature signal from a sensor (such as a thermocouple or resistance temperature detector) into an electrical signal suitable for long-distance transmission or processing. It is widely used in industrial production, building automation, HVAC systems, and other fields that require precise temperature measurement and control.

[0003] Chinese utility model patent CN213579830U discloses an insertion-type temperature transmitter. This device, by incorporating a probe, protective rod, locking nut, and heat-conducting plate, allows for adjustment of the number of heat-conducting plate components, thereby adjusting the probe insertion depth. This improves the device's applicability and economic efficiency. Furthermore, the inclusion of a protective rod, embedded rod, heat-conducting rod, connector, and main housing reduces heat loss and improves the device's detection accuracy, making it highly practical. Regarding the aforementioned related technology, the inventors believe the following drawbacks exist:

[0004] However, in actual use, the probe needs to be removed first, then a certain amount of heat-conducting sheet needs to be added inside the protective rod, and finally the probe needs to be reinstalled to adjust the detection depth. Since the insertion depth of the probe is different in different environments, operators need to frequently disassemble and reassemble the probe to add heat-conducting sheet, which reduces the efficiency of temperature detection. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable temperature transmitter. This temperature transmitter simplifies the process of adjusting the probe insertion depth.

[0006] The technical solution adopted by this utility model to solve the above problems is: an adjustable temperature transmitter, comprising:

[0007] Thermometer;

[0008] A quick-adjustment assembly includes a sleeve fixedly connected to the bottom of a thermometer. A hollow heat-conducting tube is fixedly connected inside the sleeve. A heat-conducting rod is slidably connected inside the hollow heat-conducting tube, with its bottom end extending to the outside of the hollow heat-conducting tube. A movable sleeve is fixedly connected to the outside of the heat-conducting rod. A probe is fixedly connected to the bottom of the movable sleeve. A crossbar is connected to the bottom of the thermometer. A pressing plate is fixedly connected to one end of the crossbar. A connecting rod is hinged between the end of the crossbar and the movable sleeve via a hinge. A spring is sleeved on the outside of the crossbar.

[0009] A further preferred technical solution is that one end of the spring is fixedly connected to the pressing plate.

[0010] A further preferred technical solution is that the outer side of the heat-conducting rod is in contact with the inner side of the hollow heat-conducting tube, and the bottom end of the heat-conducting rod is in contact with the top end of the probe.

[0011] A further preferred technical solution is that: two sets of crossbars are provided, respectively located on both sides of the bottom of the temperature measuring device.

[0012] A further preferred technical solution is that: both sides of the bottom of the thermometer are fixedly connected to guide brackets, and the guide brackets are slidably connected to the crossbar and fixedly connected to one end of the spring.

[0013] A further preferred technical solution is that a limiting ring is provided at the end of the crossbar away from the pressing plate.

[0014] A further preferred technical solution is that the movable sleeve is symmetrically threaded with two sets of tightening bolts.

[0015] A further preferred technical solution is that: the inner side of the movable sleeve is symmetrically and fixedly connected with limiting protrusions, and the outer side of the sleeve is provided with a limiting groove and the limiting groove is slidably connected to the limiting protrusions.

[0016] A further preferred technical solution is that the thermometer is covered with a protective sleeve.

[0017] A further preferred technical solution is that the outer surfaces of both the sleeve and the movable sleeve are provided with a heat-insulating coating layer.

[0018] In summary, this utility model has the following advantages:

[0019] 1. This utility model uses two sets of pressing plates to move the crossbar fixedly connected to them inwards simultaneously. Utilizing the sliding fit between the crossbar and the guide bracket, the hinge between the crossbar, the movable sleeve, and the connecting rod, and the sliding fit between the limiting protrusion and the limiting groove, the movable sleeve can be pushed vertically downwards. Furthermore, the sliding fit between the heat-conducting rod and the hollow heat-conducting tube allows the heat-conducting rod to move downwards as well, thus enabling rapid adjustment of the probe insertion depth. The operation is simple, convenient, and quick, effectively improving the efficiency of temperature detection. Tightening the top bolt allows for rapid positioning of the adjusted probe.

[0020] 2. After testing, this utility model allows the probe to automatically reset by loosening the tightening bolt and the spring's own rebound action, eliminating the need for manual repositioning by operators and thus improving the convenience of the device. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0028] Example:

[0029] Please combine Figure 1-4 An adjustable temperature transmitter according to this embodiment includes a thermometer 1. The thermometer 1 is covered with a protective sleeve made of rubber material, which can protect the thermometer 1 and prevent it from being damaged by impact.

[0030] A quick-adjustment assembly for rapidly adjusting the depth of probe 105 includes a sleeve 101 fixedly connected to the bottom of thermometer 1. A hollow heat-conducting tube 102 is fixedly connected inside the sleeve 101. A heat-conducting rod 103 is slidably connected inside the hollow heat-conducting tube 102, with the bottom end of the heat-conducting rod 103 extending to the outside of the hollow heat-conducting tube 102. A movable sleeve 104 is fixedly connected to the outside of the heat-conducting rod 103. The probe 105 is fixedly connected to the bottom of the movable sleeve 104. Both sides of the bottom are movably connected to crossbars 106. One end of the crossbar 106 is fixedly connected to a pressing plate 107, and the other end of the crossbar 106 is hinged to the movable sleeve 104 via a connecting rod 108. A spring 109 is sleeved on the outside of the crossbar 106, and one end of the spring 109 is fixedly connected to the pressing plate 107. The hollow heat-conducting pipe 102 and the heat-conducting rod 103 are both made of copper, which facilitates the rapid introduction of the temperature in the measurement area into the thermometer 1 for measurement, and can ensure the temperature. For normal conduction, the inner diameter of the movable sleeve 104 is the same as the outer diameter of the sleeve 101, which facilitates the movement of the movable sleeve 104 outside the sleeve 101. Guide brackets 110 are fixedly connected to both sides of the bottom of the thermometer 1, and the guide brackets 110 are slidably connected to the crossbar 106 on the same side and fixedly connected to the other end of the spring 109 on the same side, which can play a certain guiding role for the horizontal movement of the crossbar 106. A limiting ring 2 is fixedly sleeved on the outer side of the crossbar 106 away from the pressing plate 107, which can prevent the crossbar 106 from separating from the guide bracket 110. Two sets of tightening bolts 3 are symmetrically threaded on the movable sleeve 104, which can quickly position the adjusted probe 105. Two sets of limiting protrusions 4 are symmetrically fixedly connected to the inner side of the movable sleeve 104. Limiting grooves are symmetrically opened on the outer side of the sleeve 101, and the limiting grooves are slidably connected to the limiting protrusions 4 on the same side, which can play a certain guiding role for the vertical movement of the movable sleeve 104.

[0031] The implementation principle of an adjustable temperature transmitter in this embodiment is as follows: First, by pressing two sets of pressing plates 107, the pressing plates 107 can drive the crossbar 106 fixedly connected to them to move inward simultaneously. Utilizing the sliding engagement between the crossbar 106 and the guide bracket 110, the hinge between the crossbar 106 and the movable sleeve 104 and the connecting rod 108, and the sliding engagement between the limiting protrusion 4 and the limiting groove, the movable sleeve 104 can be pushed vertically downward. Under the sliding engagement between the heat-conducting rod 103 and the hollow heat-conducting tube 102, the heat-conducting rod 103 can be driven downward together, thereby enabling rapid adjustment of the insertion depth of the probe 105. The operation is simple. This method is convenient, quick, and effectively improves the efficiency of temperature detection. At this time, the spring 109 will be compressed, and then the tightening bolt 3 will be tightened to enable the adjusted probe 105 to be quickly positioned. Then, the probe 105 will be inserted into the required position for temperature detection. The heat will be conducted to the thermometer 1 through the probe 105, the heat-conducting rod 103, and the hollow heat-conducting tube 102 for measurement. The temperature of the measurement point can be obtained by the value displayed on the thermometer 1. Finally, the device can be retracted. By loosening the tightening bolt 3, the probe 105 can be automatically reset under the rebound action of the spring 109, without the need for the operator to manually return it to its position, thereby improving the convenience of the device.

[0032] Furthermore, a further improvement is made in that: the outer surfaces of the sleeve 101 and the movable sleeve 104 are both provided with a heat-insulating coating layer. Specifically, the outer surfaces of the sleeve 101 and the movable sleeve 104 are coated with polyurethane heat-insulating coating, which can reduce heat loss during heat conduction and thus ensure the accuracy of temperature detection results.
