Description

Technical Field

[0001] This utility model relates to the technical field of temperature sensor connection devices, and in particular to a temperature sensor plug-in connection device. Background Technology

[0002] Temperature sensors are key components in industrial production, medical equipment, and power systems, and their connection stability directly affects the accuracy and reliability of temperature monitoring. With the continuous improvement of modern industrial automation, higher demands are placed on the installation efficiency, adaptability, and connection security of temperature sensors. In various temperature monitoring scenarios, rapid and accurate connection between sensors and external devices has become a core element in ensuring the stable operation of monitoring systems.

[0003] Existing technologies, such as the utility model patent with publication number CN220018751U, disclose a quick connection device for a temperature sensor probe, relating to the technical field of temperature sensor probe connection devices. The device includes a base, a support rod slidably connected to one side of the base, an electric lifting device fixed to the top of the support rod, a pressure rod fixed to the power output end of the electric lifting device, and a placement groove in the center of the top of the base. This device places the temperature sensor and connector in two guide plates at opposite ends of the top of the base, and presses downwards. A limiting block enters the guide plate. When the temperature sensor and connector enter the extrusion plate, the limiting block separates from them. At this point, a second spring releases its elastic potential energy, and the limiting block extends out from inside the guide plate, preventing the temperature sensor and connector from popping out downwards from the extrusion plate. This achieves good limiting with a simple downward press, while also making retrieval convenient.

[0004] In the aforementioned technology, the distance between the two sets of extrusion plates is fixed when the device enables rapid connection between the temperature sensor and external equipment. It can only quickly connect temperature sensors of the same type, which has significant limitations in its use. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a temperature sensor plug-in connection device, comprising a base plate, a fixing frame and a plug-in structure.

[0007] The fixing frame is fixedly connected to one end of the top of the base plate. The top of the base plate is provided with a connecting groove, and rectangular grooves are provided on both sides of the connecting groove. The rectangular grooves are located on the top of the base plate. Both ends of the top of the base plate are fixedly connected with fixing frames. Each fixing frame is provided with a lead screw. One end of the lead screw is rotatably connected to the inner wall of one side of the fixing frame, and the other end of the lead screw is fixedly connected to a rotating block. The outer surface of the lead screw is threaded with a plug-in structure.

[0008] The fixing frame includes a connecting frame fixedly connected to one end of the top of the base plate, support rods fixedly connected to both sides of the connecting frame, a snap-fit ​​groove on the side of the connecting frame, and a locking post rotatably connected to the outer surface of the connecting frame.

[0009] Furthermore, the insertion and extraction structure includes a movable block threaded to the outer surface of the lead screw, a connecting plate fixedly connected to one side of the movable block, an electric actuator fixedly connected to the end of the connecting plate away from the movable block, a telescopic spring sleeved on the outer surface of the electric actuator, a clamping plate fixedly connected to the telescopic end of the electric actuator, a slot provided on the outer surface of the clamping plate, and a limit assembly fixedly connected to the outer surface of the clamping plate.

[0010] Furthermore, a limiting groove is fixedly connected to the bottom of the connecting plate, and a slider is fixedly connected to the bottom of the clamping plate, with the limiting groove and the slider cooperating with each other.

[0011] Furthermore, the limiting component includes an L-shaped plate fixedly connected to the outer surface of the clamping plate, a connecting rod fixedly connected to the surface of the L-shaped plate, a limiting block fixedly connected to one end of the connecting rod away from the L-shaped plate, a connecting spring fixedly connected between the limiting block and the L-shaped plate, the connecting spring being sleeved on the outer surface of the connecting rod, and a handle fixedly connected to the other end of the connecting rod.

Rotating the rotating block can drive the lead screw to rotate. Since the moving block is threadedly connected to the lead screw, the rotation of the lead screw will drive the moving block to move axially, thereby driving the connecting plate, electric push rod and clamping plate to move synchronously, realizing the flexible adjustment of the distance between the two sets of plug-in structures. With the guiding effect of the limiting groove and the slider, the adjustment process is ensured to be stable, so that the device can be adapted to temperature sensors of different models and lengths, greatly expanding the scope of application.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a temperature sensor plug-in connection device, including a base plate 1, a fixing frame 2 and a plug-in structure 3.

[0019] The following section will explain the specific setup and function of its fixing bracket 2 and plug-in structure 3.

[0020] In this embodiment: the fixing frame 2 is fixedly connected to one end of the top of the base plate 1. The top of the base plate 1 is provided with a connecting groove 11. Rectangular grooves 12 are provided on both sides of the connecting groove 11. The rectangular grooves 12 are located on the top of the base plate 1. Fixing frames 13 are fixedly connected to both ends of the top of the base plate 1. A lead screw 4 is provided inside the fixing frame 13. One end of the lead screw 4 is rotatably connected to the inner wall of one side of the fixing frame 13. The other end of the lead screw 4 is fixedly connected to a rotating block 41. The outer surface of the lead screw 4 is threaded with a plug-in structure 3.

[0021] The fixing frame 2 includes a connecting frame 21 fixedly connected to one end of the top of the base plate 1. Support rods 22 are fixedly connected to both sides of the connecting frame 21. The side of the connecting frame 21 has a snap-fit ​​groove 23. A locking post 24 is rotatably connected to the outer surface of the connecting frame 21.

[0022] The effects achieved by the above components are as follows: the fixed frame 13 provides stable installation support for the lead screw 4, ensuring that the lead screw 4 rotates without deviation; the rotating block 41 facilitates manual or tool-driven rotation of the lead screw 4, providing an operating point for position adjustment of the insertion and extraction structure 3; the support rod 22 can enhance the structural strength of the connecting frame 21, prevent the connecting frame 21 from deforming due to external interface pressure or insertion and extraction force, and ensure the overall stability of the fixed frame 2.

[0023] Specifically, the plug-in structure 3 includes a movable block 31 threadedly connected to the outer surface of the lead screw 4. A connecting plate 32 is fixedly connected to one side of the movable block 31. An electric push rod 33 is fixedly connected to the end of the connecting plate 32 away from the movable block 31. A telescopic spring 38 is sleeved on the outer surface of the electric push rod 33. A clamping plate 34 is fixedly connected to the telescopic end of the electric push rod 33. A slot 35 is provided on the outer surface of the clamping plate 34. A limit component 36 is fixedly connected to the outer surface of the clamping plate 34.

[0024] The effects achieved by the above components are as follows: the moving block 31 converts the rotational motion of the lead screw 4 into linear motion, realizing the overall position adjustment of the insertion and removal structure 3; the connecting plate 32 serves as the connecting carrier between the electric push rod 33 and the moving block 31, ensuring a firm connection between the two; the electric push rod 33 can provide stable axial thrust / pull force, realizing automated insertion and removal of the temperature sensor and reducing human operation errors; the telescopic spring 38 can absorb the impact force at the moment of insertion and removal when the electric push rod 33 drives the clamping plate 34 to approach or move away from the external interface, preventing damage to the sensor connector and the external interface due to rigid collision; the slot 35 can fit with the housing or wiring terminal of the temperature sensor, increasing the clamping contact area and preventing the sensor from slipping or shifting during insertion and removal; the limiting component 36 further limits and fixes the sensor, preventing the sensor from falling off in the axial direction.

[0025] Specifically, the bottom of the connecting plate 32 is fixedly connected to a limiting groove 37, and the bottom of the clamping plate 34 is fixedly connected to a slider 341. The limiting groove 37 and the slider 341 cooperate with each other.

[0026] The effect achieved by the above components is as follows: the limiting groove 37 and the slider 341 form a sliding guide structure, which can limit the movement direction of the clamping plate 34, ensure that the clamping plate 34 moves only along the extension and retraction direction of the electric push rod 33, avoid the clamping plate 34 from being laterally offset due to the driving force or insertion and extraction reaction force of the electric push rod 33, and ensure the alignment accuracy of the sensor and the external interface.

[0027] Specifically, the limiting component 36 includes an L-shaped plate 361 fixedly connected to the outer surface of the clamping plate 34. A connecting rod 362 is fixedly connected to the surface of the L-shaped plate 361. A limiting block 363 is fixedly connected to one end of the connecting rod 362 away from the L-shaped plate 361. A connecting spring 364 is fixedly connected between the limiting block 363 and the L-shaped plate 361. The connecting spring 364 is sleeved on the outer surface of the connecting rod 362. A handle 365 is fixedly connected to the other end of the connecting rod 362.

[0028] The effects achieved by the above components are as follows: the L-shaped plate 361 provides mounting support for the connecting rod 362 and the connecting spring 364; the connecting rod 362 can slide along the opening of the L-shaped plate 361, causing the limiting block 363 to move closer to or away from the sensor; the connecting spring 364 is always in a pre-compressed state, applying a spring force towards the sensor to the limiting block 363, so that the limiting block 363 tightly abuts against the sensor surface, realizing the passive limiting of the sensor; the handle 365 makes it easy to manually pull the connecting rod 362 to disengage the limiting block 363 from the sensor, facilitating the installation and removal of the sensor, and the operation is convenient and requires no additional tools.

[0029] Specifically, a circular hole is provided on the outer surface of the connecting frame 21, and a locking pin 24 is rotatably connected inside the circular hole.

[0030] The effects achieved by the above components are as follows: the circular hole provides a fulcrum for the locking pin 24 to rotate, ensuring that the locking pin 24 can rotate flexibly; when the external interface is inserted into the snap-fit ​​slot 23, rotating the locking pin 24 to press it against the edge of the external interface or into the preset snap-fit ​​slot can lock the external interface and the connecting bracket 21, preventing the external interface from moving axially or laterally due to force during insertion and removal, and ensuring the connection alignment accuracy.

[0031] Specifically, a fixing plate 14 is fixedly connected to the outer surface of the base plate 1. There are four fixing plates 14 located at the four right angles of the outer surface of the base plate 1.

[0032] The effects achieved by the above components are as follows: the fixing plates 14 at the four right angles can make the force on the base plate 1 evenly distributed, and prevent the base plate 1 from warping or displacing due to excessive local force; the fixing plates 14 extend out of the edge of the base plate 1, providing a wider installation space for the fixing bolts 15, making it easier to fix the device on the surface of workbenches or equipment of different sizes.

[0033] Specifically, the top of the fixing plate 14 is provided with a threaded hole, and the internal thread of the threaded hole is connected to a fixing bolt 15.

[0034] The effects achieved by the above components are as follows: the threaded hole cooperates with the fixing bolt 15, and the fixing plate 14 can be firmly connected to the workbench surface by tightening the fixing bolt 15, thereby fixing the base plate 1; the threaded connection is detachable, which facilitates the installation, disassembly and position adjustment of the device, and the self-locking nature of the thread structure ensures that the device will not loosen due to vibration or other factors during long-term use.

[0035] Working principle: First, place the base plate 1 on the target workbench or equipment surface, align the threaded holes of the four fixing plates 14 with the preset mounting holes on the workbench, and tighten the fixing bolts 15 until the base plate 1 is tightly attached to the mounting surface, thus completing the overall fixing of the device; align the interface end of the external equipment with the snap-fit ​​groove 23 of the connecting bracket 21, and slowly push it in so that the interface is embedded in the snap-fit ​​groove 23 until the end face of the interface is attached to the bottom of the snap-fit ​​groove 23; then rotate the locking pin 24 so that the locking pin 24 presses against the edge of the external interface, thus completing the positioning and locking of the external interface; Depending on the temperature sensor model, rotate the rotating blocks 41 at both ends of the base plate 1 to drive the lead screw 4 to rotate within the fixed frame 13. Since the moving block 31 is threadedly connected to the lead screw 4, when the lead screw 4 rotates, it drives the moving block 31 to move along the axial direction of the lead screw 4, thereby driving the connecting plate 32, the electric push rod 33, and the clamping plate 34 to move synchronously until the distance between the two sets of clamping plates 34 matches the length of the sensor. Stop rotating the rotating block 41, pull the handle 365 of the limiting assembly 36 to drive the connecting rod 362 and the limiting block 363 to move away from the clamping plate 34. At this time, the connecting spring 364 is compressed. Place both ends of the temperature sensor into the slots 35 of the two sets of clamping plates 34 respectively, and release the handle 365. 5. The connecting spring 364 releases its elastic potential energy, pushing the limiting block 363 to abut against the sensor surface, completing the clamping and fixing of the sensor. The electric push rod 33 is activated, and the telescopic end of the electric push rod 33 pushes the clamping plate 34 to move towards the fixing frame 2. During the process, the slider 341 slides along the limiting groove 37 to ensure that the clamping plate 34 moves smoothly. When the sensor connector is close to the external interface, the telescopic spring 38 begins to compress, buffering the insertion and removal impact force until the sensor connector is fully connected with the external interface, and then the electric push rod 33 is closed. If it is necessary to disassemble the sensor, the electric push rod 33 is activated in reverse to move the clamping plate 34 away from the fixing frame 2. After the sensor connector is separated from the external interface, the handle 365 can be pulled to remove the sensor.
