This structure is very cumbersome to install, reduces production efficiency, and increases maintenance difficulty. Utility Model Content

[0003] The purpose of the utility model is to solve the problems in the prior art and to provide a thermostat knob that can solve the above problems.

[0004] To achieve the above-mentioned purpose, the utility model proposes a temperature controller knob, including a knob body and a fixed ring, the bottom surface of the fixed ring is provided with a plurality of limit rods, the end of the limit rod away from the fixed ring is provided with an anti-detachment hook, the bottom surface of the fixed ring is provided with a plurality of limit blocks, the limit blocks and the limit rods are staggered, the knob body is provided with a clearance groove matching the limit rod and a limit slot matching the limit block, and the length of the limit rod is greater than the length of the limit block.

[0005] Preferably, a mounting ring protruding radially outward is provided at the bottom of the knob body, and a circle of oblique corrugations is provided at the bottom of the mounting ring, wherein the oblique corrugations are formed by a plurality of convex teeth arranged on the mounting ring.

[0006] Preferably, three limiting rods are provided and three limiting blocks are provided.

[0007] Preferably, the outer edge of the fixing ring is provided with slots matching the number of the limiting rods, and the limiting rods are located on the inner sides of the slots.

[0008] Preferably, a circle of convex strips is convexly provided on the outer surface of the knob body.

[0009] Preferably, a mounting groove is provided in the middle of the knob body.

[0010] The beneficial effects of the utility model are as follows: the utility model arranges an anti-disengagement hook on the knob, and after the three anti-disengagement hooks are inserted into the knob hole, they will be connected with the hole positions on the bakelite shell of the thermostat, clamping the limit and fixing it to prevent the knob from falling off upward, avoiding the trouble of installing balls, springs and clamping rings at the round hole positions, and achieving the same function through the limit rod and the anti-disengagement hook, saving costs, simple assembly and stable structure; the limit block presses downward against the limit to limit the height distance space between the knob and the bakelite shell of the thermostat to prevent the bottom of the knob from contacting the bakelite shell of the thermostat; the oblique corrugation cooperates with the sound wire on the bakelite shell of the thermostat, and a rattling sound will be made when it is turned, thus achieving the gear feel.

[0011] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figure 1-6, a thermostat knob comprises a knob body 1 and a fixing ring 2, wherein the bottom surface of the fixing ring 2 is provided with three limiting rods 3, and the end of the limiting rod 3 away from the fixing ring 2 is provided with an anti-disconnection hook 4, and the bottom surface of the fixing ring 2 is provided with three limiting blocks 5, and the limiting blocks 5 are staggered with the limiting rods 3. The knob body 1 is provided with a giving groove 6 matching the limiting rod 3 and a limiting slot 7 matching the limiting block 5, and the length of the limiting rod 3 is greater than the length of the limiting block 5. The bottom of the knob body 1 is provided with a mounting ring 8 protruding radially outward, and the bottom of the mounting ring 8 is provided with a circle of oblique corrugations 9, and the oblique corrugations 9 are formed by a number of convex teeth arranged on the mounting ring 8. The outer edge of the fixing ring 2 is provided with a slot 10 matching the number of the limiting rod 3, and the limiting rod 3 is located on the inner side of the slot 10. The outer surface of the knob body 1 is convexly provided with a circle of convex strips 11, and the middle of the knob body 1 is provided with a mounting groove 12.
