Description

Technical Field

[0001] This utility model relates to the field of grilling and frying equipment technology, specifically an angle limiting structure. Background Technology

[0002] In the field of cooking equipment, grills are a common kitchen utensil, and their design and performance are crucial for improving cooking efficiency and food quality. In particular, the angle limiting structure of a grill directly affects the ease of operation and safety of use, allowing the grill to operate in closed, partially open, and fully open states. However, existing grill limiting structures on the market generally have some obvious problems, as follows:

[0003] Traditional grill pan limit mechanisms are typically designed to be quite complex, involving multiple mating components such as adjustment knobs, limit gears, springs, and support frames. This complexity not only increases manufacturing costs, but also makes the limit mechanism prone to failure during daily use due to wear and loosening of the parts, thus reducing the reliability and safety of the equipment.

[0004] Complex limiting structures often mean longer assembly times and higher skill requirements. In the production process of grills, too many mating parts and complex assembly processes not only increase the production cycle, but may also lead to unstable product quality due to assembly errors, thereby reducing production efficiency. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the purpose of this utility model is to provide an angle limiting structure.

[0006] The technical solution of this utility model is: an angle limiting structure, including an upper shell assembly and a lower shell assembly. An upper baking tray and a lower baking tray are respectively fixed on the upper shell assembly and the lower shell assembly. A rotating frame is fixed on the outside of the upper shell assembly. A rocker arm is provided at both ends of the rotating frame. A rotating shaft is fixed on both the left and right sides of the rear end of the lower shell assembly. The two rotating shafts are rotatably connected to a rocker arm. A positioning seat that can extend and retract left and right is installed on one of the rotating shafts. A circular groove is provided in the end of the rocker arm connected to the rotating shaft. A limiting rib is provided in the circular groove. The positioning seat has an inner baffle rib and an outer baffle rib. The inner baffle rib extends into the circular groove, and the outer baffle rib protrudes outside the rotating shaft. When the upper baking tray is in a semi-open state, the inner baffle rib blocks the limiting rib.

[0007] Furthermore, a positioning seat is installed on the right side of the rear end of the lower shell assembly. This rotating shaft is rotatably connected to the rocker arm at the right end of the rotating frame. Both the inner and outer baffles protrude from the right end of the positioning seat.

[0008] Furthermore, a left-right extending spring is installed inside the shaft, with the right end of the spring abutting against the left end of the positioning seat.

[0009] Furthermore, the rotating shaft has a movable groove, with an opening at the right end for the positioning seat to extend into.

[0010] Furthermore, the shaft has a through-hole, and the left end of the positioning seat has a stud. The through-hole allows the stud to be inserted, and a screw extends into the through-hole. The screw is fixedly connected to the stud, and the right end of the through-hole has a retaining ring to block the left end of the screw.

[0011] Furthermore, when the upper baking pan is fully open, the inner baffle rib rests against the left side of the limiting rib.

[0012] The advantages of using the angle limiting structure provided by this utility model are: simple structure and few parts. This simplified design not only reduces manufacturing costs, but also reduces potential failure points caused by complex structures, and its assembly process is simpler. Attached Figure Description

Detailed Implementation

[0022] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0023] like Figure 1 — Figure 8 As shown, an angle limiting structure includes an upper shell assembly 1 and a lower shell assembly 2. An upper baking pan 3 and a lower baking pan 4 are fixed on the upper shell assembly 1 and the lower shell assembly 2, respectively. A rotating frame 5 is fixed on the outside of the upper shell assembly 1. A rocker arm 51 is provided at both ends of the rotating frame 5. A rotating shaft 6 is fixed on both the left and right sides of the rear end of the lower shell assembly 2. The two rotating shafts 6 are rotatably connected to a rocker arm 51, respectively. A positioning seat 7 that can extend and retract left and right is installed on one of the rotating shafts 6. A circular groove 511 is provided in the end of the rocker arm 51 connected to the rotating shaft 6. The left end of the circular groove 511 is open. A limiting rib 512 is provided in the circular groove 511. The positioning seat 7 has an inner baffle rib 71 and an outer baffle rib 72. The inner baffle rib 71 extends into the circular groove 511, and the outer baffle rib 72 protrudes outside the rotating shaft 6. When the upper baking pan 3 is in a semi-open state, the inner baffle rib 71 blocks the limiting rib 512.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, a positioning seat 7 is installed on the right side of the rear end of the lower shell assembly 2. The rotating shaft 6 is rotatably connected to the rocker arm 51 at the right end of the rotating frame 5. The inner baffle 71 and the outer baffle 72 are both protruding from the right end of the positioning seat 7.

[0025] like Figure 2 , Figure 6 As shown, a left-right extending spring 8 is installed inside the rotating shaft 6, with the right end of the spring 8 abutting against the left end of the positioning seat 7. The rotating shaft 6 has a movable groove 61, the right end of which is open for the positioning seat 7 to extend into. The rotating shaft 6 has a through-hole 62, and the left end of the positioning seat 7 has a stud 73. The stud 73 is inserted into the through-hole 62, and a screw 9 extends into the through-hole 62, fixing the screw 9 to the stud 73. The right end of the through-hole 62 has a retaining ring 621 to block the left end of the screw 9. The retaining ring 621 prevents the positioning seat 7 from falling off. When the positioning seat 7 is pressed to the left by hand, the positioning seat 7 moves to the left, compressing the spring 8.

[0026] like Figure 8 As shown, when the upper baking pan 3 is fully open, the inner baffle 71 rests against the left side of the limiting rib 512. At this time, the spring 8 is in a compressed state. When the upper baking pan 3 is rotated to a half-open state, the inner baffle 71 separates from the limiting rib 512. At the instant, the spring 8 drives the inner baffle 71 to move to the right, and the inner baffle 71 blocks the limiting rib 512 again.

[0027] Will Figure 7 Rotate the upper baking pan to the desired state. Figure 3In the current state, the inner baffle 71 blocks the limiting rib 512, restricting the upper baking tray 3 from continuing to rotate. By pressing the positioning seat 7 to the left, the limiting rib 512 is released from the restraint of the inner baffle 71, and the upper baking tray 3 can rotate to... Figure 8 state.

[0028] The angle limiting structure provided by this utility model has a simple structure and a small number of parts. This simplified design not only reduces manufacturing costs but also reduces potential failure points caused by complex structures, and its assembly process is simpler.

[0029] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
