Description

Technical Field

[0001] The utility model relates to the technical field of sudden jump type thermostats, in particular to a sudden jump temperature control aluminum cover. Background Art

[0002] The operating principle of the snap-action temperature-control aluminum cover is based on a bimetallic strip as a temperature-sensing component. When the appliance is operating normally, the bimetallic strip is in a free state, and the contacts are either closed or open. When the temperature reaches the operating temperature, the bimetallic strip generates internal stress and rapidly actuates, opening or closing the contacts, interrupting or connecting the circuit, thereby controlling the temperature. When the appliance cools to the reset temperature, the contacts automatically close or open, resuming normal operation. Existing snap-action temperature-control aluminum covers have a smooth contact surface with the snap switch. This smooth surface does not limit the snap switch, making it prone to rotation and affecting its sensitivity. Utility Model Content

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sudden temperature control aluminum cover, comprising an aluminum cover body, the aluminum cover body comprising a base plate, a surrounding plate and a cap, the four sides of the base plate are bent downward to form the surrounding plate, the cap is arranged in the middle of the base plate, the top circumferential array of the cap has a plurality of protrusions formed by being concave from the outside to the inside, the protrusions match the grooves on the metal cover surface of the sudden switch, and the base plate is provided with a connecting hole for connecting the sudden switch.

[0005] Furthermore, the connecting hole is connected to the fixing hole on the kick switch through a fixing piece.

[0006] Furthermore, a logo is printed on the upper end surface of the cap.

[0007] Furthermore, the number of the connecting holes is at least two, and the two connecting holes are symmetrically arranged at both ends of the length direction of the base plate. There is residual material at the connecting holes, and the residual material extends downward to form a positioning ring, and the diameter of the positioning ring matches the fixing hole.

[0008] Furthermore, a fixing plate is provided on one side of the enclosure close to the wire connecting plate of the kick switch.

[0009] Furthermore, a concave and convex heat-conducting surface is provided on the bottom plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention has a plurality of protrusions formed by depressions from the outside to the inside in a circular array on the top circumference of the cap, and the protrusions match the grooves on the metal cover surface of the kick switch. After the protrusions on the cap are pressed into the grooves, the protrusions limit the kick switch, and the kick switch will not rotate. Therefore, the present invention effectively improves the sensitivity of the kick switch. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0016] Example: Please refer to Figure 1-3 The bottom plate 101 is provided with a connecting hole 3 for connecting the sudden jump switch 2, and the aluminum cover body 103 is fixed on the sudden jump switch 2 through the connecting hole 3.

[0017] In an optional embodiment, the connecting hole 3 is connected to the fixing hole 5 on the sudden trip switch 2 through a fixing piece. The fixing piece can be a bolt. The bolt passes through the fixing hole 5 from the connecting hole 3 to fix the aluminum cover body 1 to the sudden trip switch 2.

[0018] In an optional embodiment, a logo is printed on the upper end surface of the cover cap 103 , and the provision of the logo can facilitate the matching of the models of the aluminum cover body 1 and the kick switch 2 .

[0019] In an optional embodiment, the number of connecting holes 3 is at least two, and the two connecting holes 3 are symmetrically arranged at both ends of the length direction of the base plate 101. There is residual material left at the connecting holes 3, and the residual material extends downward to form a positioning ring 4. The diameter of the positioning ring 4 matches the fixing hole 5. The positioning ring 4 can be inserted into the fixing hole 5. The positioning ring 4 can quickly align the connecting hole 3 and the fixing hole 5 with each other to avoid misalignment of the aluminum cover body 1 and the jump switch 2.

[0020] In an optional embodiment, a fixing piece 6 is provided on one side of the enclosure 102 close to the wire connection piece of the kick switch 2 for fixing the aluminum cover body 1 .

[0021] In an optional embodiment, the bottom plate 101 is provided with a concave and convex heat-conducting surface 7 for quickly transferring and dissipating heat, protecting the internal structure and extending the service life of the product.

[0022] The working principle of this embodiment is as follows: when assembling the kick switch 2, the aluminum cover body 1 is pressed onto the kick switch 2, the protrusion 104 on the cover cap 103 is pressed into the groove on the metal cover surface of the kick switch 2, and the connecting hole 3 is connected to the fixing hole 5 using bolts, thereby fixing the aluminum cover body 1 and the kick switch 2. Under the limiting action of the protrusion 104, the kick switch 2 will not rotate, so the utility model effectively improves the sensitivity of the kick switch 2.
