Description

Technical Field

[0001] This invention relates to the field of temperature controllers, and particularly to a physical temperature controller for power equipment. Background Technology

[0002] The temperature controller is an integrated intelligent temperature control instrument. It adopts a fully digital integrated design and features programmable or fixed-point constant temperature control, multiple PID regulation, output power limiting curve programming, manual / automatic switching, soft start, alarm switch output, real-time data query, and computer communication functions. It combines a digital display temperature instrument and a ZK thyristor voltage regulator into one unit, integrating temperature measurement, regulation, and drive. During actual operation, the device automatically samples and monitors the ambient temperature in real time through a temperature sensor. When the ambient temperature exceeds the control set value, the control circuit is activated, and the fan can be set to start for cooling. If the temperature continues to rise, the over-limit alarm function is activated when it reaches the set over-limit alarm temperature point. If the controlled temperature cannot be effectively controlled, the device can be stopped by tripping to prevent damage.

[0003] The temperature controller has a display screen and buttons at the front and terminals at the rear. These terminals connect the temperature controller to the fan system, temperature probe, alarm, etc. Therefore, multiple cables need to be connected to these terminals. Currently, this is often done by winding the copper wire at the cable end around a threaded post and tightening it. However, connecting multiple cables to these posts requires repeated tightening and loosening of the threads, which is not only laborious but also reduces wiring efficiency. Furthermore, repairing or replacing multiple sets of cables is time-consuming and labor-intensive. Since the copper wire and threads are exposed, dust and moisture in the air accelerate corrosion of the copper core and threads, affecting not only power transmission but also the screwing in and out of the threads.

[0004] Therefore, it is necessary to invent a physical temperature controller for electrical equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a physical temperature controller for power equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a physical temperature controller for power equipment, comprising a temperature controller body, a mounting plate fixedly provided at the rear end of the temperature controller body, a cable connection hole for installing cables penetrating through the top of the mounting plate, a conductive copper sheet electrically connected to the inside of the cable connection hole on the inner wall of the cable connection hole, rubber rings fixedly provided at both ends of the cable connection hole, a rotating groove communicating with the inside of the cable connection hole on the surface of the mounting plate, a clamping block for pressing the cable end against the surface of the conductive copper sheet inside the rotating groove, a threaded rod screwed into a threaded hole on the clamping block, the rotating groove comprising a cylindrical section and a square section, the section of the rotating groove near the cable connection hole being a square section, the clamping block being located inside the square section, a hollow tube coaxially connected to the inside of the cylindrical section, the hollow tube being unable to move along its own axial direction, one end of the hollow tube being fixedly connected to the threaded rod, the end of the hollow tube away from the threaded rod extending out of the outer port of the rotating groove, multiple sets of hollow tubes being provided, and a rotating assembly for driving multiple sets of hollow tubes to rotate synchronously at the end of the hollow tube;

[0007] The rotating assembly includes a rotating disk fixedly connected to the outer end of the hollow tube and a conveyor belt passing through the outer circumference of the rotating disk. The rotating disk is coaxially arranged with the hollow tube. An annular limiting groove is formed on the outer circumference of the rotating disk.

The hollow tube is provided with a limiting component to prevent the pushing column from rotating along its axial direction.

[0010] Preferably, the limiting component includes a connecting rod, a square piece, and a limiting groove. The limiting groove is formed on the inner wall of the hollow tube. The limiting groove and the square piece are slidably connected to each other. The side of the square piece facing the push column is fixedly connected to the push column through the connecting rod.

[0011] Preferably, the clamping block has a pressure rod on the side facing the conductive copper sheet. The pressure rod is located on the clamping block away from the cable connection hole port. A bending groove is formed on the inner wall of the cable connection hole at the position opposite to the pressure rod.

[0012] Preferably, the inside of the cable connection hole is provided with a baffle to limit the cable, located inside the bending groove, and the baffle is provided with a dust blowing component to blow dust from inside the cable connection hole to the port of the cable connection hole.

[0013] Preferably, the soot blowing assembly includes an air jet nozzle, an air jet channel, a spring compression tube, and an air supply chamber. The air supply chamber is located inside the baffle. One end of the spring compression tube near the conductive copper sheet is fixedly connected to one end of the air supply chamber. The other end of the spring compression tube away from the conductive copper sheet can move back and forth inside the air supply chamber, and the other end of the spring compression tube away from the conductive copper sheet is in a sealed state. An air extraction pipe is fixedly provided on the outer surface of the baffle. One end of the air extraction pipe is interconnected with the end of the spring compression tube near the conductive copper sheet, and the other end of the air extraction pipe extends out of the outer surface of the mounting plate. An air jet nozzle is provided on the side wall of the baffle facing the pressure rod. The air jet nozzle is interconnected with the end of the spring compression tube near the conductive copper sheet through the air jet channel in the baffle layer structure. A one-way valve is provided inside the air extraction pipe and the air jet channel. The air jet nozzle is located on the baffle at the end away from the conductive copper sheet. The pressure rod and the clamping block are in contact with the surface of the baffle. The moving direction of the clamping block is opposite to the moving direction of the end of the spring compression tube away from the conductive copper sheet.

[0014] Preferably, a sealing plate is fixedly provided at the end of the spring compression tube away from the conductive copper sheet, and the side of the sealing plate away from the conductive copper sheet is fixedly connected to one end of the pull rope. The other end of the pull rope extends out of the end of the baffle and is fixedly connected to the outer periphery of the hollow tube.

[0015] Preferably, the rear end of the temperature controller body is provided with an embedding groove, the inside of which is embedded a rotating handle, and the surface of the rotating handle is fixed with a plug rod that matches the plug groove.

[0016] Preferably, the rear end of the temperature controller body is also provided with a hinge plate, one end of which is movably hinged to the surface of the temperature controller body, and a cutting blade is fixedly provided on the side of the hinge plate facing the temperature controller body.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. This invention utilizes teeth on rotating disks and a transmission belt. When a specific set of rotating disks needs to rotate, the teeth on that set of rotating disks simply extend into the annular limiting groove and engage with the transmission belt. At this time, the rotation of any one set of rotating disks corresponding to the teeth engaging with the transmission belt can drive the rotation of several other sets of rotating disks. This allows multiple sets of clamping blocks to simultaneously clamp or loosen the corresponding cables, eliminating the need to loosen or tighten the hollow tubes one by one. Multiple sets of hollow tubes can be loosened or tightened at once, meaning multiple sets of cables are simultaneously clamped onto the surface of the corresponding conductive copper sheet, thereby achieving electrical connection between the cables and the temperature controller body. This connection method is faster and can greatly save installation and disassembly time. Furthermore, since the exposed part of the cable is located inside the cable connection hole, the rubber ring seals the port of the cable connection hole, effectively preventing external moisture and dust from entering the inside of the cable connection hole. This delays the corrosion of the copper core of the cable and extends the service life of the cable.

[0019] 2. As the threaded rod rotates and drives the clamping block to gradually approach the conductive copper sheet, the clamping rod will first contact the exposed end of the cable and press the exposed end of the cable into the inside of the bending groove, thereby causing the exposed end of the cable to bend. The clamping rod presses the cable into the inside of the bending groove, effectively preventing the cable from separating from the clamping block and the conductive copper sheet, making the cable connection more secure and stronger in tensile strength.

[0020] 3. The baffle acts as a limiter for the cable. When the exposed end of the cable touches the surface of the baffle, the pressure bar on the pressure block can press the exposed end of the cable into the bending groove when the pressure block moves down. At the same time, the baffle is equipped with a dust blowing component that blows the dust inside the cable connection hole to the port of the cable connection hole. The dust blowing component can blow out the dust inside the cable connection hole, thereby avoiding the accumulation of dust that will increase the resistance and affect the power transmission. It also prevents the acid or alkaline substances in the dust from corroding the copper core of the cable.

[0021] 4. The rotating handle and plug rod can rotate the push column. When in use, remove the rotating handle from the embedded groove and insert the plug rod into the plug groove on the push column. Then, rotating the rotating handle will rotate the push column, which in turn will rotate the rotating disk, hollow tube and threaded rod, so that the clamping block can clamp and loosen the cable. The cable can be connected and disconnected without the need for additional tools such as pliers and wrenches, avoiding the trouble of finding disassembly and assembly tools and improving the efficiency of cable connection and disconnection.

[0022] 5. This invention can cut the cable insulation by lifting the hinge plate and placing the cable end in a position corresponding to the cutting blade, without the need for additional scissors or pliers. This avoids the inability to connect or disconnect cables when there are no tools or the wrong tools are carried. Attached Figure Description

[0033] This invention provides, for example Figures 1-7 The diagram shows a physical temperature controller for electrical equipment, comprising a controller body 1. A mounting plate 2 is fixedly mounted at the rear end of the controller body 1. The top of the mounting plate 2 has a through-hole 3 for mounting cables. The inner wall of the cable connection hole 3 has a conductive copper sheet 20 electrically connected to the interior of the controller body 1. Rubber rings 19 are fixedly mounted at both ends of the cable connection hole 3. A rotating groove 39, communicating with the interior of the cable connection hole 3, is formed on the surface of the mounting plate 2. Inside the rotating groove 39 are clamping blocks 24 that press the cable ends against the surface of the conductive copper sheet 20. A threaded rod 23 is threaded into the threaded hole on the 4. The rotating groove 39 includes a cylindrical section and a square section. The section of the rotating groove 39 near the cable connection hole 3 is a square section. The clamping block 24 is located inside the square section. A hollow tube 16 is rotatably connected to the cylindrical section. The hollow tube 16 cannot move along its own axial direction. One end of the hollow tube 16 is fixedly connected to the threaded rod 23. The end of the hollow tube 16 away from the threaded rod 23 extends out of the outer port of the rotating groove 39. Multiple sets of hollow tubes 16 are provided. The end of the hollow tube 16 is provided with a rotating assembly that drives multiple sets of hollow tubes 16 to rotate synchronously.

[0034] The rotating assembly includes a rotating disk 4 fixedly connected to the outer end of the hollow tube 16 and a conveyor belt 5 passing through the outer periphery of the rotating disk 4. The rotating disk 4 is coaxially arranged with the hollow tube 16. An annular limiting groove 6 is provided on the outer periphery of the rotating disk 4. The conveyor belt 5 passes through the annular limiting groove 6 on each set of rotating disks 4. The bottom of the annular limiting groove 6 is provided with a receiving groove 29 arranged in an equidistant annular pattern around the axis of the rotating disk 4. The receiving groove 29 is provided with teeth 30 that can move closer to or away from the conveyor belt 5. When the teeth 30 extend into the interior of the annular limiting groove 6, the teeth 30 and the conveyor belt 5 mesh with each other.

[0035] In actual operation, when the teeth 30 extend into the annular limiting groove 6, the teeth 30 mesh with the conveyor belt 5. The conveyor belt 5, during transmission, drives the rotation of the rotating disk 4 corresponding to the teeth 30, thereby rotating the hollow tube 16 and the threaded rod 23. Specifically, when the teeth 30 on a set of rotating disks 4 extend into the annular limiting groove 6 and mesh with the conveyor belt 5, the transmission of the conveyor belt 5 will drive the rotation of that set of rotating disks 4. Therefore, when installing multiple sets of cables, the teeth 30 on the rotating disks 4 at the corresponding installation positions can be extended into the annular limiting groove 6 to mesh with the conveyor belt 5, and then the cables can be inserted into the corresponding cable connection holes 3. Inside the opening, the rubber ring 19 at the cable connection hole 3 can "pre-fix" the cable, thus preventing the cable from easily detaching from the cable connection hole 3. Then, any set of rotating disks 4 that mesh with the transmission belt 5 can be rotated. The rotating disks 4 will drive multiple sets of rotating disks 4 corresponding to the cable to rotate simultaneously through the transmission belt 5. The rotation of the rotating disks 4 will drive the rotation of the threaded rod 23 through the hollow tube 16. Due to the square segment on the rotating groove 39 limiting the clamping block 24, the rotation of the threaded rod 23 drives the clamping block 24 to move along the axial direction of the threaded rod 23. The rotation of the rotating disks 4 in different directions can drive the clamping block 24 away from or closer to the conductive copper sheet 20, thereby clamping or loosening the cable.

[0036] In order to prevent the hollow tube 16 from moving along its own axis and to allow the hollow tube 16 to rotate around its own axis, a limiting ring 17 can be fixedly provided on the outer periphery of the hollow tube 16. The limiting ring 17 is slidably connected to the annular limiting slide rail 18 inside the mounting plate 2, so that the hollow tube 16 can achieve the above-mentioned movement mode.

[0037] This invention utilizes the teeth 30 on the rotating disk 4 and the transmission belt 5. When a specific set of rotating disks 4 needs to rotate, the teeth 30 on that set of rotating disks 4 simply extend into the annular limiting groove 6 and engage with the transmission belt 5. At this time, the rotation of any one set of rotating disks 4 corresponding to the teeth 30 engaging with the transmission belt 5 will drive the rotation of several other sets of rotating disks 4. This allows multiple sets of clamping blocks 24 to simultaneously clamp or loosen their corresponding cables, eliminating the need to individually tighten or loosen the hollow tubes 16 one by one. Multiple sets of hollow tubes 16 can be loosened or tightened at the same time, which means that multiple sets of cables are pressed onto the surface of the corresponding conductive copper sheet 20 at the same time, thereby realizing the electrical connection between the cable and the temperature controller body 1. This connection method is faster and can save a lot of installation and disassembly time. Since the exposed part of the cable is located inside the cable connection hole 3, the rubber ring 19 seals the port of the cable connection hole 3, which can effectively prevent external moisture and dust from entering the interior of the cable connection hole 3. By delaying the corrosion of the copper core of the cable, the service life of the cable is extended.

[0038] It should be noted that the conveyor belt 5 can be a chain, chain plate, gear belt, etc., and is not limited to the one shown in the figure. The teeth 30 can also be straight teeth, helical teeth, etc. The conveyor belt 5 and the teeth 30 are matched with each other.

[0039] To enable the back-and-forth movement of the tooth 30, a circular groove 15 is provided on the side of the rotating disk 4 facing away from the hollow tube 16. The storage groove 29 is connected to the interior of the circular groove 15. A limiting plate 31 is provided inside the storage groove 29. The tooth 30 is fixedly connected to the side of the limiting plate 31 facing the conveyor belt 5. The side of the limiting plate 31 facing away from the tooth 30 is fixedly connected to one end of the movable rod 33. The other end of the movable rod 33 extends into the interior of the circular groove 15. A fixing ring 32 is fixedly provided at the end of the storage groove 29 near the circular groove 15. The movable rod 33 passes through the interior of the fixing ring 32. The fixing ring 32 and the limiting plate 31 are fixedly connected by a tension spring. A pushing component is provided inside the circular groove 15 to push the movable rod 33 toward the direction of the annular limiting groove 6.

[0040] In actual operation, when the pushing component presses the movable rod 33 at one end inside the circular groove 15, the other end of the movable rod 33 will drive the teeth 30 into the annular limiting groove 6 and mesh with the conveyor belt 5. Then, when the conveyor belt 5 is driven, it will drive the rotating disk 4 corresponding to the set of teeth 30 to rotate. When the pushing component releases the end of the movable rod 33 inside the circular groove 15, the movable rod 33 will move towards the circular groove 15 under the action of the tension spring fixedly connected to the limiting plate 31, thereby realizing the back-and-forth movement of the teeth 30 inside the receiving groove 29. When the teeth 30 move towards the annular limiting groove 6, the teeth 30 will mesh with the conveyor belt 5. When the teeth 30 are stored inside the receiving groove 29, the transmission of the conveyor belt 5 will not drive the rotation of the rotating disk 4 corresponding to the set of teeth 30.

[0041] Specifically, the pushing assembly includes a pushing column 7, with an insertion groove 8 at the outer end of the pushing column 7. One end of the pushing column 7 located inside the circular groove 15 has a frustum-shaped structure, and the diameter of the pushing column 7 near the hollow tube 16 is smaller than the diameter of the pushing column 7 away from the hollow tube 16. The hollow tube 16 has a limiting assembly inside to prevent the pushing column 7 from rotating along its axial direction.

[0042] In actual operation, when the push column 7 moves towards the mounting plate 2, the outer periphery of the push column 7 will press against one end of the movable rod 33, causing the movable rod 33 to push the teeth 30 into the interior of the annular limiting groove 6 and engage with the conveyor belt 5. When the push column 7 moves away from the mounting plate 2, the outer periphery of the push column 7 gradually releases the pressure on the end of the movable rod 33, causing the movable rod 33 to move towards the circular groove 15 under the action of the tension spring fixedly connected to the limiting plate 31. The teeth 30 will also disengage from the conveyor belt 5 and be stored inside the storage groove 29.

[0043] The limiting component can prevent the push column 7 from rotating along its axis, so that the rotation of the push column 7 can drive the rotation of the rotating disk 4, which in turn drives the rotation of the hollow tube 16 and the threaded rod 23, so that the clamping block 24 can clamp and release the cable.

[0044] The limiting assembly includes a connecting rod 25, a square piece 26, and a limiting groove 27. The inner wall of the hollow tube 16 is provided with a limiting groove 27. The limiting groove 27 and the square piece 26 are slidably connected to each other. The side of the square piece 26 facing the push column 7 is fixedly connected to the push column 7 through the connecting rod 25.

[0045] Specifically, the square piece 26 and the limiting groove 27 work together to prevent the push column 7 from rotating along its axis. At the same time, the frictional resistance between the square piece 26 and the inner wall of the limiting groove 27 can further prevent the push column 7 from moving back and forth along its axis inside the circular groove 15, thus improving the positioning effect of the tooth 30. Furthermore, the square piece 26 can be covered with elastic materials such as rubber, which further improves the positioning effect of the square piece 26 inside the limiting groove 27, thus improving the fixation of the push column 7 inside the circular groove 15. This makes the tooth 30 more stable when it extends into the annular limiting groove 6, preventing external forces from accidentally causing the tooth 30 to be retracted into the storage groove 29.

[0046] The clamping block 24 has a pressure rod 34 on the side facing the conductive copper sheet 20. The pressure rod 34 is located on the clamping block 24 away from the cable connection hole 3. A bending groove 21 is formed on the inner wall of the cable connection hole 3 opposite to the pressure rod 34.

[0047] In actual operation, as the threaded rod 23 rotates and drives the clamping block 24 to gradually approach the conductive copper sheet 20, the clamping rod 34 will first contact the exposed end of the cable and press the exposed end of the cable into the inside of the bending groove 21, thereby causing the exposed end of the cable to bend. The clamping rod 34 presses the cable into the inside of the bending groove 21, thus effectively preventing the cable from separating from the clamping block 24 and the conductive copper sheet 20, making the cable connection more secure and stronger in tensile strength.

[0048] To allow the pressure bar 34 to more easily bend the exposed end of the cable, the bottom side of the pressure bar 34 facing the cable can be designed as a curved surface, such as... Figure 7 As shown in the image.

[0049] The inside of the cable connection hole 3 is provided with a baffle 22 inside the bending groove 21 to limit the cable, and the baffle 22 is provided with a dust blowing component to blow the dust inside the cable connection hole 3 to the port of the cable connection hole 3.

[0050] In actual operation, the baffle 22 serves to limit the cable. When the exposed end of the cable touches the surface of the baffle 22, the pressure rod 34 on the pressure block 24 can press the exposed end of the cable into the bending groove 21 when the pressure block 24 moves down. At the same time, the baffle 22 is equipped with a dust blowing component that blows the dust inside the cable connection hole 3 to the port of the cable connection hole 3. The dust blowing component can blow out the dust inside the cable connection hole 3, thereby avoiding the accumulation of dust that leads to increased resistance and affects the power transmission. It also prevents acidic or alkaline substances in the dust from corroding the copper core of the cable.

[0051] Specifically, the soot blowing assembly includes an air jet nozzle 36, an air jet channel 37, a spring compression tube 38, and an air supply chamber 40. The air supply chamber 40 is located inside the baffle 22. One end of the spring compression tube 38 near the conductive copper sheet 20 is fixedly connected to one end of the air supply chamber 40. The end of the spring compression tube 38 away from the conductive copper sheet 20 can move back and forth inside the air supply chamber 40, and the end of the spring compression tube 38 away from the conductive copper sheet 20 is in a sealed state. An air extraction pipe 28 is fixedly provided on the outer surface of the baffle 22. One end of the air extraction pipe 28 is interconnected with the end of the spring compression tube 38 near the conductive copper sheet 20. The other end of the air pipe 28 extends out of the outer surface of the mounting plate 2. The side wall of the baffle 22 facing the pressure rod 34 has an air nozzle 36. The air nozzle 36 is connected to the end of the spring compression pipe 38 near the conductive copper sheet 20 through the air channel 37 in the layer structure of the baffle 22. The air pipe 28 and the air channel 37 are both equipped with one-way valves. The air nozzle 36 is located on the baffle 22 at the end away from the conductive copper sheet 20. The pressure rod 34 and the clamping block 24 are both in contact with the surface of the baffle 22. The moving direction of the clamping block 24 is opposite to the moving direction of the end of the spring compression pipe 38 away from the conductive copper sheet 20.

[0052] like Figure 7As shown, when the end of the spring compression tube 38 away from the conductive copper sheet 20 moves away from the conductive copper sheet 20, the spring compression tube 38 gradually extends. At this time, outside air will enter the interior of the spring compression tube 38 through the air extraction tube 28. When the end of the spring compression tube 38 away from the conductive copper sheet 20 moves closer to the conductive copper sheet 20, the spring compression tube 38 will gradually compress. Then, the air inside the spring compression tube 38 will be blown out through the air jet channel 37 and the air jet port 36, thereby blowing out the dust inside the cable connection hole 3 from the port of the cable connection hole 3. The moving direction of the clamping block 24 is opposite to the moving direction of the end of the spring compression tube 38 away from the conductive copper sheet 20. That is, when the clamping block 24 gradually moves closer to the conductive copper sheet 20 and presses the cable against the surface of the conductive copper sheet 20, the spring compression tube... 38 gradually moves and extends away from the conductive copper sheet 20. At this time, the outside gas enters the interior of the spring compression tube 38 through the suction tube 28. Since the air jet 36 is blocked by the surface of the clamping block 24, the gas inside the spring compression tube 38 can be stored inside the spring compression tube 38. When it is necessary to remove the cable from the cable connection hole 3, the clamping block 24 gradually moves away from the conductive copper sheet 20. When the pressure rod 34 is about to disengage from the port of the air jet 36, the cable is first pulled out from the interior of the cable connection hole 3. Then, the rotating disk 4 is rotated to make the pressure rod 34 disengage from the port of the air jet 36. At this time, the spring compression tube 38 will contract under its own elasticity. The gas inside the spring compression tube 38 will be ejected through the air jet channel 37 and the air jet 36, thereby blowing the dust inside the cable connection hole 3 out from the port of the cable connection hole 3.

[0053] This invention draws outside air into the spring compression tube 38 for storage when the cable is pressed against the surface of the conductive copper sheet 20. When the cable needs to be removed from the cable connection hole 3, the gas inside the spring compression tube 38 can be ejected from the jet nozzle 36 on the baffle 22 to clean the dust inside the cable connection hole 3. The cable can be pulled out from the cable connection hole 3 first, and then the gas inside the spring compression tube 38 can be released, so that all the gas inside the spring compression tube 38 is used to blow out the dust inside the cable connection hole 3. The greater the gas flow, the better the dust blowing effect. At the same time, it can also heat up the cable and the conductive copper sheet 20.

[0054] It should be noted that, in order to ensure the sealing effect of the clamping block 24 and the pressure rod 34 on the air jet 36, sealing components such as rubber gaskets can be installed on the side of the clamping block 24 and the pressure rod 34 facing the baffle 22. Furthermore, to improve the cleaning effect inside the cable connection hole 3, the rubber ring 19 should be designed to not significantly obstruct the port of the cable connection hole 3. Figure 1 and Figure 5As shown, the holes on the rubber ring 19 can be in an eccentric position so that dust can be ejected from the cable connection hole 3, and the port of the jet nozzle 36 should be tilted toward the holes on the rubber ring 19 to achieve a better dust blowing effect.

[0055] Meanwhile, it is best to provide a spring element on the outer periphery of the spring compression tube 38 so that the spring compression tube 38 has a stronger ability to return to the compressed state, thereby squeezing out more air force from the inside of the spring compression tube 38 and achieving a better ash blowing effect.

[0056] A sealing plate 35 is fixedly provided at one end of the spring compression tube 38 away from the conductive copper sheet 20. The side of the sealing plate 35 away from the conductive copper sheet 20 is fixedly connected to one end of the pull rope. The other end of the pull rope extends out of the end of the baffle 22 and is fixedly connected to the outer periphery of the hollow tube 16.

[0057] Specifically, when the hollow tube 16 rotates in one direction, the clamping block 24 gradually approaches the conductive copper sheet 20, and the pressure rod 34 first blocks the air jet 36. Then, the clamping block 24 keeps the air jet 36 blocked. At the same time, the hollow tube 16 winds the pull rope, and the pull rope drives the sealing plate 35 to move away from the conductive copper sheet 20. The spring compression tube 38 gradually extends and draws out the outside gas through the exhaust tube 28. Conversely, when the hollow tube 16 rotates in the opposite direction, the clamping block 24 gradually moves away from the conductive copper sheet 20, and the pull rope gradually unwinds outside the hollow tube 16. When the pressure rod 34 moves to the position where it is disengaged from the air jet 36, the spring compression tube 38 will rebound under its own elasticity, and the gas inside the spring compression tube 38 will also be ejected from the air jet 36 for cleaning the inside of the cable connection hole 3.

[0058] It should be noted that the sealing plate 35 is relatively lightweight, and the elasticity of the spring compression tube 38 is sufficient to move the sealing plate 35 and cause the spring compression tube 38 to retract. The end of the pull rope away from the sealing plate 35 can be connected to the outer periphery of the limiting ring 17. In order to avoid friction between the pull rope and the inner wall of the annular limiting slide rail 18, a gap can be reserved between the limiting ring 17 and the annular limiting slide rail 18 for the pull rope to wind.

[0059] The rear end of the temperature controller body 1 is provided with an embedding groove 12, and a rotating handle 10 is embedded inside the embedding groove 12. A plug-in rod 11 that matches the plug-in groove 8 is fixed on the surface of the rotating handle 10.

[0060] The rotating handle 10 and the plug rod 11 can rotate the push column 7. When in use, the rotating handle 10 is taken out from the embedded groove 12 and the plug rod 11 is inserted into the plug groove 8 on the push column 7. At this time, rotating the rotating handle 10 will rotate the push column 7, which in turn will rotate the rotating disk 4, the hollow tube 16 and the threaded rod 23, so that the clamping block 24 can clamp and loosen the cable. The cable can be connected and disconnected without the need for additional tools such as pliers and wrenches, avoiding the trouble of finding disassembly and assembly tools and improving the efficiency of cable connection and disconnection.

[0061] The rear end of the temperature controller body 1 is also provided with a hinge plate 13. One end of the hinge plate 13 is movably hinged to the surface of the temperature controller body 1, and a cutting blade 14 is fixedly provided on the side of the hinge plate 13 facing the temperature controller body 1.

[0062] In actual use, the cable end can be placed in the position corresponding to the cutting blade 14 by lifting the hinge plate 13, so that the cable can be cut without the need to use scissors or pliers. This avoids the inability to connect and disconnect cables when there are no tools or the wrong tools are carried.

[0063] Working Principle: In actual operation, when the teeth 30 extend into the annular limiting groove 6, the teeth 30 mesh with the conveyor belt 5. The conveyor belt 5 then drives the rotation of the corresponding rotating disk 4, which in turn drives the rotation of the hollow tube 16 and the threaded rod 23. Specifically, when the teeth 30 on a particular set of rotating disks 4 extend into the annular limiting groove 6 and mesh with the conveyor belt 5, the transmission of the conveyor belt 5 will drive the rotation of that set of rotating disks 4. Therefore, when installing multiple cables, the teeth 30 on the rotating disks 4 at the corresponding installation positions can be extended into the annular limiting groove 6 to mesh with the conveyor belt 5, and then the cables can be inserted into the corresponding cable connection holes. Inside port 3, the rubber ring 19 at the cable connection hole 3 can "pre-fix" the cable, thus preventing the cable from easily detaching from the cable connection hole 3. Then, any set of rotating disks 4 that mesh with the transmission belt 5 can be rotated. The rotating disks 4 will drive multiple sets of rotating disks 4 corresponding to the cable to rotate simultaneously through the transmission belt 5. The rotation of the rotating disks 4 will drive the rotation of the threaded rod 23 through the hollow tube 16. Due to the square segment on the rotating groove 39 limiting the clamping block 24, the rotation of the threaded rod 23 drives the clamping block 24 to move along the axial direction of the threaded rod 23. The rotation of the rotating disks 4 in different directions can drive the clamping block 24 away from or closer to the conductive copper sheet 20, thereby clamping or loosening the cable.

[0064] In order to prevent the hollow tube 16 from moving along its own axis and to allow the hollow tube 16 to rotate around its own axis, a limiting ring 17 can be fixedly provided on the outer periphery of the hollow tube 16. The limiting ring 17 is slidably connected to the annular limiting slide rail 18 inside the mounting plate 2, so that the hollow tube 16 can achieve the above-mentioned movement mode.

[0065] This invention utilizes the teeth 30 on the rotating disk 4 and the transmission belt 5. When a specific set of rotating disks 4 needs to rotate, the teeth 30 on that set of rotating disks 4 simply extend into the annular limiting groove 6 and engage with the transmission belt 5. At this time, the rotation of any one set of rotating disks 4 corresponding to the teeth 30 engaging with the transmission belt 5 will drive the rotation of several other sets of rotating disks 4. This allows multiple sets of clamping blocks 24 to simultaneously clamp or loosen their corresponding cables, eliminating the need to individually tighten or loosen the hollow tubes 16 one by one. Multiple sets of hollow tubes 16 can be loosened or tightened at the same time, which means that multiple sets of cables are pressed onto the surface of the corresponding conductive copper sheet 20 at the same time, thereby realizing the electrical connection between the cable and the temperature controller body 1. This connection method is faster and can save a lot of installation and disassembly time. Since the exposed part of the cable is located inside the cable connection hole 3, the rubber ring 19 seals the port of the cable connection hole 3, which can effectively prevent external moisture and dust from entering the interior of the cable connection hole 3. By delaying the corrosion of the copper core of the cable, the service life of the cable is extended.

[0066] It should be noted that the conveyor belt 5 can be a chain, chain plate, gear belt, etc., and is not limited to the one shown in the figure. The teeth 30 can also be straight teeth, helical teeth, etc. The conveyor belt 5 and the teeth 30 are matched with each other.
