[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a digital display temperature controller, including a shell 1, the shell 1 is made of high-strength ABS plastic material, has excellent heat resistance and impact resistance, and ensures stability and durability in various environments. A connecting wire 2 is arranged at the right end of the shell 1. The connecting wire 2 is made of flexible PVC material and is long enough to be conveniently connected to a power supply or other control system. The connecting wire 2 contains multiple copper core wires to ensure the stability and safety of current transmission. Extension blocks 3 are slidably connected to both sides of the bottom of the shell 1, and are designed as a slidable structure to facilitate the disassembly and maintenance of the shell 1. The bottoms of the two extension blocks 3 are fixedly connected with a back cover 4, which is also made of ABS plastic material, and is used to protect the electronic components inside the controller from dust and moisture. It is also convenient for users to perform later maintenance or replacement of parts. Control rods 5 are slidably connected to both sides of the shell 1.

[0033] The outside of the control rod 5 is engaged with the through hole of the extension block 3, and the outside of the control rod 5 is engaged with the through hole of the extension block 3, so that the control rod 5 can be stable during use without worrying about falling off. The top of the control rod 5 is fixedly connected to a sliding plate 6, and the outside of the sliding plate 6 is slidably connected to the inner wall of the shell 1. The sliding of the control rod 5 can be controlled by the sliding plate 6. Springs 7 are provided on both sides of the top of the shell 1. One end of the spring 7 is fixedly connected to the inner wall of one side of the shell 1, and the other end of the spring 7 is fixedly connected to one side of the sliding plate 6. In this way, the sliding plate 6 can squeeze the spring 7 when moving, so that the spring 7 is deformed to generate elastic potential energy, and is used to support the sliding plate 6 and automatically returns to the initial position when there is no operation, ensuring the smooth operation and rapid recovery of the control rod 5. U-shaped rods 8 are slidably connected to both sides of the bottom of the shell 1, and the outside of the U-shaped rod 8 is engaged with the through hole of the control rod 5, so that a stable supporting structure can be formed. The outside of the U-shaped rod 8 is fixedly connected to a limiting block 9, and the outside of the limiting block 9 is slidably connected to the inner wall of the shell 1. Springs 10 are arranged inside both sides of the bottom of the shell 1, one end of the spring 10 is fixedly connected to one side of the inner wall of the shell 1, and the other end of the spring 10 is fixedly connected to one side of the limiting block 9. The design of the spring 10 is similar to that of the spring 1 7, in order to ensure the smooth operation and rapid recovery of the U-shaped rod 8.

[0034] Both sides of the bottom of the rear cover 4 are fixedly connected with limiting components, and the limiting components include two limiting frames 11. The tops of the two limiting frames 11 are respectively fixedly connected to the two sides of the bottom of the rear cover 4, and both sides of the outer wall of the limiting frame 11 are fixedly connected with a fixed shell 12, and the fixed shell 12 can be limited by the limiting frame 11. The external thread of the fixed shell 12 is connected with a screw rod 13, and the screw rod 13 can move in the fixed shell 12 when it rotates. The inner wall of the screw rod 13 is rotatably connected with a blocking block 14, and the blocking block 4 can be pushed to move by the screw rod 13. The outside of the connecting line 2 contacts the outside of the blocking block 14, and the side of the screw rod 13 away from the blocking block 14 is fixedly connected with a handle 15, and the screw rod 13 can be conveniently rotated by the handle 15. The four external sides of the shell 1 are fixedly connected with protective sleeves 16, which makes the shell 1 more sturdy.

[0035] refer to Figure 4 A display panel 17 is provided on the top of the shell 1, and the device can be adjusted through the display panel 17. An integrated circuit board 18 is provided at the bottom of the display panel 17, and an ECU control module 19 is provided on the top of the integrated circuit board 18. The integrated circuit board 18 provides a circuit system for the shell 1 for use by the device. The ECU control module 19 can receive information detected by an external temperature sensor and then display the detected temperature through the display panel 17.

[0036] Working principle: when disassembly is required, the U-shaped rod 8 is pulled, and the limiting block 9 can be driven to move under the pulling of the U-shaped rod 8. The movement of the limiting block 9 can squeeze the spring 10 so that the spring 10 is deformed and generates elastic potential energy. At this time, the U-shaped rod 8 can withdraw from the bottom through hole of the control rod 5, and then the control rod 5 is pulled, and the sliding plate 6 can be driven to move and squeeze the spring 1 7 under the pulling of the control rod 5, so that the spring 1 7 is deformed and generates elastic potential energy. At this time, the inner wall of the extension block 3 can be withdrawn under the movement of the control rod 5, so that The rear cover 4 and thus the bottom of the shell 1 can be removed to complete the disassembly. When installation is required, the U-shaped rod 8 is repeatedly pulled, and then the control rod 5 is pulled to insert the extension block 3 into the bottom of the shell 1. At this time, the control rod 5 and the U-shaped rod 8 are released in turn. The control rod 5 will be driven to reset by the sliding plate 6 under the elastic potential energy of the spring 1 7, so that the control rod 5 engages with the inner wall of the extension block 3, and the U-shaped rod 8 will be driven to reset by the limiting block 9 under the elastic potential energy of the spring 2 10, so that the U-shaped rod 8 engages with the bottom through hole of the control rod 5, thereby limiting the control rod 5 and completing the installation of the rear cover 4.

[0037] In daily use, when the connecting line 2 is too long and inconvenient to use, the connecting line 2 can be placed on the inner wall of the limiting frame 11. At this time, by rotating the handle 15, the rotation of the handle 15 can drive the screw rod 13 to rotate, and the rotation of the screw rod 13 can drive the blocking block 14 to move, so that the connecting line 2 can be restricted by the movement of the blocking block 14, and the connecting line 2 can be restricted to the inner wall of the limiting frame 11 for easy storage.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
