Description

Technical Field

[0001] This utility model relates to the field of electric heating push rod technology, and in particular to an energy-saving electric heating push rod. Background Technology

[0002] A thermostat is a valve that controls the flow path of automotive coolant. The device that drives the thermostat to open and close is called an electric heating push rod. The electric heating push rod is driven by the principle of thermal expansion and contraction. Paraffin wax is added inside the electric heating push rod. When the paraffin wax is exposed to high temperature, it melts and its volume increases, which in turn pushes the push rod, allowing the thermostat to open and close.

[0003] For example, the authorized announcement number "CN218293700U" is named thermostat electric heating push rod. By placing the high-temperature wire and external wiring inside the protective box, the wire connector of the thermostat electric heating push rod will not be easily damaged or loosened. By pressing the button to squeeze the locking block, the heating plate of the thermostat electric heating push rod can be easily removed and replaced.

[0004] The above-mentioned and existing technologies have the following defects: the electric heating push rod uses the elastic force of the spring to make the locking block abut against the sleeve. Due to vibration, the connecting block is prone to falling off; moisture and impurities can easily enter the pressure plate along the stud of the adjusting bolt, causing poor contact between the high temperature wire and the external wiring. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving electrothermal push rod.

Paraffin wax is provided between the lower surface of the piston and the inner wall of the sleeve. A copper block is provided at the opening of the lower inner wall of the sleeve. A heating plate is rotatably connected to the inner wall of the copper block. A first connecting block is provided on the lower surface of the heating plate. The first connecting block is threadedly connected to the lower inner wall of the sleeve. The first connecting block has multiple wiring posts extending to the outside. A second connecting block is provided below the first connecting block. The upper surface of the second connecting block has wiring slots corresponding to the wiring posts. The lower inner wall of each wiring slot has a metal base. The upper surface of the metal base has multiple elastic conductive blocks with locking blocks on their inner surfaces. Each wiring post has a locking groove on its surface. The locking blocks engage with the locking grooves. A rotating cap is rotatably connected to the lower part of the second connecting block. The rotating cap is threadedly connected to the lower outer surface of the sleeve. A conductive wire is provided on the lower surface of the second connecting block, which is electrically connected to the metal base and the elastic conductive blocks.

[0008] Preferably, a limiting block is provided on the lower surface of the second connecting block.

[0009] Preferably, a first sealing gasket is provided between the first connecting block and the second connecting block.

[0012] Preferably, the lower surface of the sleeve is provided with an annular groove, and the upper surface of the first connecting block is provided with an annular protrusion, the annular protrusion extending into the annular groove.

[0013] The present invention proposes an energy-saving electric heating push rod, which has the following advantages: the electric heating push rod is threaded to the lower inner wall of the sleeve through the first connecting block, and the first connecting block is not allowed to fall off under the influence of vibration; the push rod is threaded to the lower outer surface of the sleeve through the rotating cap, and water vapor and impurities are blocked to the outside of the rotating cap, thus avoiding poor contact between the elastic conductive block and the terminal block.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4An energy-saving electric heating push rod includes a sleeve 1. A piston 2 with a push rod at its upper end is slidably connected to the inner wall of the sleeve 1. Paraffin wax 3 is disposed between the lower surface of the piston 2 and the inner wall of the sleeve 1. A copper block 4 is disposed at the opening of the lower inner wall of the sleeve 1. A heating plate 5 is rotatably connected to the inner wall of the copper block 4. A first connecting block 6 is disposed on the lower surface of the heating plate 5. The first connecting block 6 is threadedly connected to the lower inner wall of the sleeve 1. The first connecting block 6 has multiple wiring posts 7 extending to the outside. A second connecting block 8 is disposed below the first connecting block 6. The upper surface of the second connecting block 8... Each terminal block 7 has a corresponding terminal slot 9. The inner wall of each terminal slot 9 has a metal base 10. The upper surface of the metal base 10 has multiple elastic conductive blocks 11 with locking blocks 12 on their inner surfaces. Each terminal block 7 has a slot 13 on its surface, and the locking blocks 12 engage with the slots 13. A rotating cap 14 is rotatably connected to the lower part of the second connecting block 8. The rotating cap 14 is threaded to the lower outer surface of the sleeve 1. The lower surface of the second connecting block 8 has conductive wires 15 electrically connected to the metal base 10 and the elastic conductive blocks 11. When the heating plate 5 is activated, the paraffin wax 3 melts, which in turn lifts the piston 2 and the push rod, allowing the thermostat to open and close.

[0021] The lower surface of the second connecting block 8 is provided with a limiting block 16. The limiting block 16 is provided to prevent the rotating cap 14 from falling off.

[0022] A first sealing gasket 17 is provided between the first connecting block 6 and the second connecting block 8. The first sealing gasket 17 makes the connection between the first connecting block 6 and the second connecting block 8 tighter.

[0023] The rotating cap 14 has multiple anti-slip grooves 18 distributed circumferentially on its surface. These anti-slip grooves 18 facilitate the rotation of the rotating cap 14.

[0024] The lower part of the sleeve 1 is provided with a support platform 19, and a second sealing gasket 20 is provided between the rotating cap 14 and the support platform 19. The second sealing gasket 20 makes the connection between the rotating cap 14 and the support platform 19 tighter.

[0025] The lower surface of the sleeve 1 has an annular groove 21, and the upper surface of the first connecting block 6 has an annular protrusion 22 that extends into the annular groove 21. By having the annular protrusion 22 extend into the annular groove 21, the first connecting block 6 and the sleeve 1 are connected more tightly.

[0026] Working principle: When installing the heating plate 5, it is inserted into the copper block 4 and threaded to the lower inner wall of the sleeve 1 via the first connecting block 6. The heating plate 5 is then fixed, and multiple elastic conductive blocks 11 are inserted through the wiring post 7. The elasticity of the multiple elastic conductive blocks 11 causes the locking block 12 to engage with the locking groove 13. Then, the rotating cap 14 is threaded to the lower outer surface of the sleeve 1 to fix the second connecting block 8. In summary, the electric heating push rod is threaded to the lower inner wall of the sleeve 1 via the first connecting block 6, and the first connecting block 6 is not allowed to fall off due to vibration. The rotating cap 14 is threaded to the lower outer surface of the sleeve 1, and moisture and impurities are blocked to the outside of the rotating cap 14, avoiding poor contact between the elastic conductive block 11 and the wiring post 7.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
