This can cause the plug-in joint to be directly stressed and deformed, thereby affecting disassembly. Therefore, the present application provides a low-power electric proportional valve to meet the needs. Utility Model Content

[0035] Example: Reference Figure 1-5 A low-power electric proportional valve shown in the figure comprises a mounting sleeve 3 and a valve body 1. The valve body 1 is an existing electric proportional valve structure, which is a prior art and will not be described in detail. The valve body 1 is connected to the mounting sleeve 3 through a plurality of plugs 4, and an adjustment structure and a limiting structure for synchronously limiting the plurality of plugs 4 are provided on the top of the mounting sleeve 3. The adjustment structure and the limiting structure cooperate with each other.

[0036] The adjustment structure can be automatically reset and can drive the limit structure to move closer to and away from the plug 4;

[0037] The limiting structure moves closer to and farther from the plug 4, thereby limiting and releasing each plug 4, and in the process of approaching and farther from the plug 4, the limiting structure drives the plug 4 to rotate and cooperate with the thread of the installation sleeve 3;

[0038] The valve body 1 is inserted into the installation sleeve 3 through the insertion frame 2 and fixedly connected through the plug 4;

[0039] The plug 4 passes through the installation sleeve 3 and the plug frame 2 . A screw groove 17 is provided at the bottom end of the plug 4 . The bottom of the plug 4 is threadedly connected to the installation sleeve 3 .

[0040] During installation, the adjusting structure is first used to move the limiting structure away from the plug 4, and then the valve body 1 is fixed by the plug 4 and the installation sleeve 3, and then the force on the adjusting structure is released, and the adjusting structure will automatically reset so that the limiting structure is close to the plug 4 and contacts with the plug 4. After contacting with the plug 4, the plug 4 can be driven to rotate first, so that the screw groove 17 is threadedly connected with the installation sleeve 3, and then the plug 4 is limited.

[0041] By setting the adjustment structure and the limiting structure, the adjustment structure can drive the limiting structure to reset, thereby driving the multiple plugs 4 to rotate and the mounting sleeve 3 to be threadedly connected, preliminarily strengthening the connection strength and stability, and also resisting the side wall of the plug 4, thereby performing a secondary limiting force, and the limiting effect is better. In the event of bumps or shocks, the force on the plug 4 can be alleviated by the double force at the threaded connection and the resistance, avoiding its deformation and damage that affects the subsequent maintenance of the valve body 1, and during disassembly and assembly, the control of the multiple plugs 4 can be completed by controlling the adjustment structure, and the disassembly and assembly are simple and convenient.

[0042] like Figure 3 As shown, the adjustment structure includes a shaft 6 which is rotatably connected to the top of the mounting sleeve 3 and can be automatically reset. A gear 7 is fixedly sleeved on the shaft 6, and the gear 7 cooperates with the limiting structure;

[0043] The top of the mounting sleeve 3 is fixedly connected with a mounting cover 5 , and the other end of the shaft rod 6 extending out of the top of the mounting cover 5 is fixedly connected with a turntable.

[0044] Rotating the turntable can drive the shaft rod 6 to rotate, and the rotation of the shaft rod 6 will drive the gear 7 to rotate, thereby cooperating with the rotation of the gear 7 and the limiting structure.

[0045] The mounting cover 5 can protect the internal structure, prevent the gear 7 from being affected by dust, and prevent it from directly contacting with the outside world and bumping, etc. At the same time, the method of rotating the turntable is simple and convenient, and the overall production cost is lower.

[0046] like Figure 3 As shown, a torque spring 8 is sleeved on the shaft 6;

[0047] Two ends of the torque spring 8 are fixedly connected to the gear 7 and the mounting cover 5 respectively.

[0048] When the shaft rod 6 rotates, the torque spring 8 will be driven to rotate synchronously, and the torque spring 8 will generate a torsion force. When the shaft rod 6 loses its force, the torque spring 8 will release the torsion force synchronously, thereby driving the shaft rod 6 to rotate and reset.

[0049] The torque spring 8 is set to enable the shaft rod 6 to automatically reset after rotation, without the need to rotate the shaft rod 6 again. The operation is simple and convenient, and the production cost is reduced. The design of the torque spring 8 can also provide a resistance force to the gear 7, which can stabilize the gear 7 and prevent it from being easily displaced.

[0050] like Figure 3 As shown, the limiting structure includes a mounting plate 9 slidably connected to the mounting cover 5, one end of the mounting plate 9 is fixedly connected to a toothed plate 12, and the toothed plate 12 is meshed with the gear 7;

[0051] A sliding block 10 is fixedly connected to the top of the mounting plate 9 , a sliding rail 11 is fixedly connected to the inside of the mounting cover 5 , and the sliding block 10 is slidably connected to the inside of the sliding rail 11 .

[0052] The rotation of gear 7 will mesh with tooth plate 12, thereby driving the installation plate 9 to move. At the same time, during the displacement of installation plate 9, the sliding block 10 on the installation plate 9 will slide along the slide rail 11, and the installation plate 9 will be driven to move back and forth or reciprocatingly through the forward and reverse rotation of gear 7.

[0053] The sliding block 10 and the slide rail 11 are provided with a limit guide structure for the displacement of the mounting plate 9, so that the mounting plate 9 will be displaced along a fixed track, thereby avoiding the mounting plate 9 from moving out of place during use. The installation of the slide rail 11 on the mounting cover 5 also enhances the structural strength of the mounting cover 5, thereby avoiding the mounting cover 5 from being easily damaged after being bumped.

[0054] like Figure 3-4 As shown, both ends of the mounting plate 9 extend out of the outside of the mounting cover 5 and are fixedly connected with an oblique rack 13, which cooperates with the plug 4;

[0055] The plug 4 is provided with an oblique thread groove 16 , and the oblique rack 13 is meshed with the oblique thread groove 16 .

[0056] When the mounting plate 9 is close to the plug 4, the bevel rack 13 will contact the plug 4, thereby engaging with the bevel thread groove 16, thereby driving the plug 4 to rotate in the forward direction. When the mounting plate 9 is away from the plug 4, the bevel rack 13 will gradually reset to one side, and in the process of resetting, it will engage with the bevel thread groove 16 to drive the plug 4 to rotate in the reverse direction.

[0057] like Figure 4 As shown, a fixing card 14 is fixedly connected to the mounting plate 9, and a card slot 15 is also provided on the plug 4, and the fixing card 14 and the card slot 15 cooperate with each other;

[0058] The clamping groove 15 is located above the oblique thread groove 16 .

[0059] In summary, when the plug 4 cooperates with the bevel rack 13 and is threadedly connected to the mounting sleeve 3, as the bevel rack 13 moves, the fixing card 14 on the mounting plate 9 will be inserted into the inside of the card slot 15, thereby providing pressure on the side wall of the plug 4, thereby limiting the plug 4.

[0060] The opening of the card slot 15 enables the fixing card 14 to not only provide limiting force on the side wall of the plug 4, but also be inserted into the card slot 15 to conflict with the bottom wall of the card slot 15, thereby providing upper and lower limiting forces for the plug 4, making its connection more stable.

[0061] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to 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 utility model shall be included in the protection scope of the present utility model.
