Implementation

[0024] refer to Figures 1 to 7 As shown, a telescopic knob switch installation structure is shown, including a telescopic knob 1, a front baffle 2 and a mounting frame 3. The telescopic knob 1 is provided with a button cover 11 at the front end, and the button cover 11 is provided with an appearance cover 4 on the outside; the front baffle 2 is provided with a mounting through hole 21, and a buckle 22 is provided outside the mounting through hole 21; a through hole 31 corresponding to the mounting through hole 21 is provided at the center of the mounting frame 3, and a slot 32 engaged with the buckle 22 is provided outside the through hole 31, and the appearance cover 4 passes through the mounting through hole 21 and the through hole 31, and the front end of the appearance cover 4 is pressed against the inner edge of the mounting through hole 21.

[0025] As shown in the attached drawings, the appearance sleeve 4 is sleeved outside the button cover 11 of the telescopic knob 1, and is placed into the mounting through hole 21 from the back of the front baffle 2. The front of the appearance sleeve 4 is pressed against the inner edge of the mounting through hole 21. The through hole 31 of the mounting frame 3 is buckled from the outside of the appearance sleeve 4 to the front baffle 2, and is fixed by the peripheral card slot 32 and the card buckle 22. The appearance sleeve 4, the telescopic knob 1, the front baffle 2 and the mounting frame 3 are all installed in sequence along the axial direction, and the operation is very convenient and smooth. The card slot 32 and the card buckle 22 are fast and accurate. The button cover 11 can be axially telescopic in the appearance sleeve 4 without direct contact with the mounting through hole 21 to avoid scratching. The card buckle 22 and the card slot 32 are respectively arranged around the mounting through hole 21 and the through hole 31 of the front baffle 2 and the mounting frame 3. After the card connection, it can ensure that the mounting through hole 21 and the through hole 31 are always coaxial, and ensure that the inner and outer appearance sleeve 4 and the telescopic knob 1 are always coaxial during the working process.

[0026] Furthermore, it also includes a barrel-shaped fixing seat 5, the open end edge of the fixing seat 5 extends laterally to have a clamping wing 51 and a clamping platform 52 spaced apart from each other in the upper and lower directions, the edge of the through hole 31 is provided with a notch 33 for the clamping platform 52 to pass through, and a gap is left between the clamping wing 51 and the clamping platform 52 for clamping the edge of the through hole 31.

[0027] As shown in the accompanying drawings, the barrel-shaped fixing seat 5 accommodates the core shaft and other internal components of the telescopic knob 1. During installation, after the clamping platform 52 passes through the notch 33, the fixing seat 5 is rotated to clamp the edge of the through hole 31 in the gap between the clamping wing 51 and the clamping platform 52. The installation operation is simple and convenient.

[0028] Furthermore, a clamping edge 41 is extended laterally from the front end edge of the appearance cover 4, and a plurality of top blocks 42 are evenly distributed on the inner side of the clamping edge 41. A step edge 211 is provided on the inner side of the mounting through hole 21 for the outer side of the clamping edge 41 to be pressed tightly against, and the outer end face of the fixing seat 5 is pressed against the top block 42.

[0029] As shown in the accompanying drawings, the top block 42 distributed on the inner side of the clamping edge 41 can, on the one hand, act as a reinforcing rib, and at the same time, can tighten the outer end surface of the fixing seat 5, and can apply force evenly to ensure the stable position of the appearance sleeve 4, providing a stable and reliable telescopic channel for the button cover 11.

[0030] Furthermore, the locking wing 51 and the locking platform 52 are staggered, and a boss 34 is protruding outward from the notch 33 , and the bottom surface of the locking wing 51 is pressed against the boss 34 .

[0031] As shown in the drawings, the boss 1 34 is located outside the notch 33, which can enhance the strength around the notch 33 and also slightly thicken the edge thickness of the through hole 21 that needs to be clamped, so that the fixing base 5 can be rotated and clamped more tightly.

[0032] Furthermore, it also includes a panel 6 , a mounting hole 61 is opened in the middle of the panel 6 , a mounting platform 23 corresponding to the mounting hole 61 is protruded from the front of the front baffle 2 , and the installation through hole 21 is opened in the mounting platform 23 .

[0033] As shown in the drawings, after the embedding platform 23 is inserted into the embedding hole 61, it can be fixed with glue, and the surface of the panel 6 is smooth and beautiful after installation.

[0034] Furthermore, there are three evenly distributed locking wings 51 , one of which is formed into an elastic cantilever 55 by a radially opened open groove 54 in the middle, and a second boss 56 is convexly provided on the bottom surface of the elastic cantilever 55 to press against the corresponding first boss 34 .

[0035] As shown in the drawings, during the installation and rotation of the fixing seat 5, the boss 2 56 causes the elastic cantilever 55 to undergo a certain elastic deformation outward, thereby increasing the clamping force between the boss 1 34 and the corresponding boss 1 34 to prevent loosening.

[0036] Furthermore, the outer contour of the mounting frame 3 is square, and the card slots 32 are opened at the upper and lower parts.

[0037] As shown in the attached drawings, the square mounting frame 3 is made of a plate, and its four sides are bent downward to enclose a receiving space. There are two pairs of slots 32 and buckles 22, respectively, at the upper and lower edges of the square mounting frame 3. It is easy to observe and snap during the snap installation, making the installation very convenient. For the convenience of lighting indication, a lamp hole 35 is also opened on the mounting frame 3, and an indicator light 7 is snapped in the lamp hole 35.

[0038] Furthermore, there are two mounting through holes 21 .

[0039] As shown in the drawings, a functional knob switch and an adjustable knob switch, or other knobs, such as a thermostat, etc., can be installed in the installation through hole 21 as needed.

[0040] Furthermore, an annular groove 411 is formed on the outer side of the clamping edge 41 , and an elastic gasket is installed in the annular groove. The elastic gasket presses against the inner side of the step edge 211 .

[0041] As shown in the drawings, the elastic washer can make the fixing seat 5 further press against the appearance sleeve 4, and at the same time provide axial extrusion buffer for the appearance sleeve 4, ensuring that the inner side of the clamping edge 41 and the step edge 211 of the appearance sleeve 4 are evenly stressed and elastically pressed against each other.
