Detailed Description

The knob of the electric appliance temperature-adjusting coupler of the utility model is further explained with reference to fig. 1 to 2.

A knob subassembly of an electric appliance temperature-adjusting coupler is characterized in that: comprising a knob 1 and an adjusting rod 3. The lower extreme of knob 1 has two at least and connects foot 2, and the specific quantity of connecting foot 2 can set up according to the demand of reality, can be two, three or four etc. connect foot 2 to be provided with two in this embodiment. The two connecting feet 2 are separated and symmetrically arranged to form a guide groove 25 between the two connecting feet 2, and the lower end of each connecting foot 2 is formed with an external barb 21, and the knob 1 can be hooked on the mounting hole of the shell through the external barbs 21. The upper side rod body 31 of the adjusting rod 3 is partially circumferentially limited and can be axially movably matched in the guide groove 25, and the lower side rod body 32 of the adjusting rod 3 is provided with a threaded section 321, and the threaded section 321 is in threaded fit connection with a mounting plate in the temperature controller.

Based on the structure, the knob 1 can rotate in the circumferential direction and is axially limited and clamped on the mounting hole of the shell through the connecting foot 2, the upper side rod body 31 of the adjusting rod 3 is partially matched in the guide groove 25, and meanwhile, the threaded section 321 of the adjusting rod 3 is matched on the mounting plate of the temperature controller. When the knob 1 rotates, the adjusting rod 3 is driven to rotate, and after the adjusting rod 3 rotates, the adjusting rod moves up and down along the guide groove 25 under the action of the thread matching force of the mounting plate, so that two contact pieces in the temperature controller are driven to be attached or separated, and the temperature control effect is achieved. In the structure, because the connecting foot 2 is divided into two pieces, when the connecting foot 2 is clamped into the mounting hole of the shell, the lower end of the connecting foot 2 can be elastically deformed inwards so as to facilitate the assembly of the knob 1 on the shell; after the assembly is finished, the barb 21 can be hooked on the inner side of the shell, so that the tensile effect can be achieved, the problem that the knob 1 is accidentally pulled outwards to drive the adjusting rod 3 to move back to the temperature controller together is solved, and the matching stability of the knob assembly and the temperature controller is obviously improved; finally, after the barb 21 is used for limiting, the arrangement of a spring can be saved, the structure can be simplified, and the stability of the matching of the knob assembly with the shell and the temperature controller can be improved.

Each connecting leg 2 is provided with a limiting step 22, and a fitting groove 23 is formed between the barb 21 and the limiting step 22. The assembling groove 23 is used for clamping the hole wall of the mounting hole of the shell, namely the outer surface of the shell is attached to the limiting step 22, so that a gap is generated between the lower surface of the knob 1 and the outer surface of the shell, and an operator can conveniently rotate the knob 1; meanwhile, the formation of the fitting groove 23 also facilitates the storage of lubricating oil to achieve a lubricating effect.

The bottoms 231 of the assembling grooves 23 are of arc structures, and the bottoms 231 of the two assembling grooves 23 are two arcs on the same circle, so that the bottoms 231 are matched with the wall of the mounting hole of the shell, and the knob 1 can rotate stably.

The guide groove 25 extends through the lower surface of the knob 1 to the inside of the knob 1. Under this structure, can make the upside body of rod 31 of adjusting lever 3 enter into the knob inside to play limiting displacement to the radial of adjusting lever 3.

The guide groove 25 penetrates the knob 1 from the bottom to the top, and a knob cover 4 is provided on the upper surface of the knob 1. This structure can facilitate the assembly of the adjustment lever 3 to the knob 1 from the upper side of the knob 1. Namely, when the knob 1 is assembled on the shell, the adjusting rod 3 is inserted into the guide groove 25 from the upper side of the knob 1 until the adjusting rod 3 moves down to the threaded hole positions on the threaded section 321 and the mounting plate, the knob 1 is rotated, the threaded section 321 can be screwed into the threaded hole of the mounting plate, and the connection between the adjusting rod 3 and the temperature controller is realized.

The guide groove 25 is of a square structure, the upper side rod body 31 of the adjusting rod 3 is matched with the guide groove 25 in shape, namely, the adjusting rod 3 is of a square structure, a circumferential limiting axially movable structure is formed on the knob 1 by the adjusting rod 3, and the lower side rod body 32 of the adjusting rod 3 is of a cylindrical structure.
