An improved structure for a grill knob switch

Abstract

This utility model discloses an improved structure for a grill's rotary switch, including a rotary switch installed inside the grill's outer shell. The outer shell has a through-hole, with a switch bracket inside the through-hole. The switch bracket has through-holes on both the top and bottom sides. A threaded rod on the rotary switch passes through these through-holes and is threadedly connected to a lock nut. A drive rod on the rotary switch protrudes through the threaded rod and is plugged into a drive knob. A drive hole corresponding to the position and shape of the drive rod is located in the middle of the inner side of the drive knob. Mounting lugs are integrally formed on both sides of the switch bracket, each with a mounting hole. The outer shell of the grill has threaded holes corresponding to the mounting holes. The advantages are: novel structure, quick installation, self-installation of the knob, saving overall packaging volume, and suitability for single-lamp or double-lamp structures.

Description

Technical Field

[0001] This utility model relates to an improved structure of a grill, and more particularly to an improved structure of a grill knob switch. Background Technology

[0002] Grills are common electric cooking appliances used daily, typically for grilling sandwiches and other foods. Existing grills have several drawbacks: the knob / switch protrudes beyond the casing, increasing the overall packaging height and requiring larger boxes, thus wasting packaging materials; furthermore, the complex switch installation structure makes assembly difficult, affecting production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an improved structure for the knob switch of a grill, addressing the shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following measures:

[0005] An improved structure for a griddle knob switch includes a knob switch installed inside the griddle housing. The griddle housing has an internally and externally penetrating mounting hole. A switch bracket is provided inside the mounting hole. The switch bracket has a switch through hole in the middle, penetrating both the upper and lower sides. A threaded rod on the knob switch passes through the switch through hole and is threadedly connected to a switch locking nut. A switch drive rod on the knob switch protrudes through the threaded rod and is inserted into a drive knob. A drive hole corresponding to the position and shape of the switch drive rod is provided in the middle of the inner side of the drive knob. Mounting ear caps are integrally formed on both sides of the switch bracket. Mounting ear caps have mounting holes. The griddle housing has threaded holes corresponding to the positions of the mounting holes. A screw passes through the mounting hole and is threaded into the threaded hole. The screw fixes the switch bracket to the inner side of the griddle housing.

[0006] The switch drive rod does not extend beyond the outer surface of the grill housing;

[0007] The inner side of the drive knob is provided with an elastic barb for holding the inner edge of the mounting through hole;

[0008] The switch bracket has two lamp holes located opposite each other on its inner side. One lamp hole can be equipped with an indicator light, or both lamp holes can be equipped with indicator lights.

[0009] The switch bracket and drive knob are both made of light-transmitting material, and the drive knob has a light-transmitting window hole corresponding to the position of the lamp hole;

[0010] The wall of the lamp hole extends from the inside out to form a limiting post for limiting the rotation of the knob.

[0011] The advantages of this utility model are: practicality, novel structure, quick installation, high efficiency, the knob part can be installed by the user, saving the overall volume of the packaging, saving packaging materials, reducing production costs, and improving production efficiency. It is suitable for the production of single-lamp or double-lamp structures. Attached Figure Description

[0016] An improved structure for a griddle knob switch includes a knob switch 2 installed inside a griddle housing 1. The griddle housing 1 has a through-hole 101 extending both internally and externally. A switch bracket 3 is located inside the through-hole 101. A switch through-hole 301 extending both vertically and horizontally is located in the center of the switch bracket 3. A threaded rod 201 of the knob switch 2 passes through the switch through-hole 301 and is threadedly connected to a switch locking nut 4. A switch drive rod 202 of the knob switch 2 protrudes through the threaded rod 201. The drive rod 202 is plugged into and connected to the drive knob 5. The drive knob 5 has a drive hole 501 at the middle of its inner side, which corresponds to the position and shape of the switch drive rod 202. The switch bracket 3 has mounting ear caps 302 integrally formed on both sides. The mounting ear caps 302 have mounting holes 303. The grill shell 1 has a threaded hole 102 corresponding to the position of the mounting hole 303. The screw passes through the mounting hole 303 and is threaded into the threaded hole 102. The screw fixes the switch bracket 3 to the inner side of the grill shell 1.

[0017] like Figure 1-4As shown, during installation, first insert the indicator light 6 into the light hole 304. Depending on the grill's functional requirements, one or two indicator lights 6 can be installed. Then, pass the threaded rod 201 of the rotary switch 2 through the switch through hole 301 and thread the switch locking nut 4 onto the threaded rod 201, thus installing the rotary switch 2 onto the switch bracket 3. Next, thread the switch bracket 3 and rotary switch 2 together onto the inside of the grill's outer casing 1, with screws passing through the mounting hole 303 and threaded into the threaded hole 102. When installing the drive knob 5, it can be installed at the factory, which inevitably increases the overall product height, packaging material, and packaging costs. Because the installation structure of the drive knob 5 in this invention is simple and convenient, it can also be placed inside the packaging box for user self-installation, thus reducing the overall product packaging height, packaging volume, and the use of packaging materials. When installing the device, the user simply aligns the drive hole 501 with the switch drive rod 202 and inserts them together. The elastic barb 502 on the inner side of the drive knob 5 passes over the mounting through hole 101 and hooks onto the inner edge of the mounting through hole 101, thus completing the installation of the drive knob 5.

[0018] The switch drive rod 202 does not extend beyond the exterior of the grill housing 1.

[0019] The inner side of the drive knob 5 is provided with an elastic barb 502 for hooking the inner edge of the mounting through hole 101.

[0020] The switch bracket 3 has two lamp holes 304 located opposite each other on its inner side. An indicator light 6 is installed in one lamp hole 304 or both lamp holes 304 are equipped with indicator lights 6.

[0021] The switch bracket 3 and the drive knob 5 are both made of light-transmitting material, and the drive knob 5 is provided with a light-transmitting window 503 corresponding to the position of the lamp hole 304.

[0022] The wall of the lamp hole 304 extends from the inside to the outside to form a limiting post 305 for rotating the limiting drive knob 5. The limiting angle is 90 degrees. After rotating the drive knob 5 90 degrees, the grill can be turned on and the indicator light 6 will light up.
