[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model proposes a pot lid with a locking device, including a lid body 1, see reference. Figure 1 The cover 1 is fixed with a positioning seat 11. The cover 1 is provided with a through hole 12. A pressure valve 4 is provided in the through hole 12. The positioning seat 11 is provided with an adjustment cavity 111. Both ends of the adjustment cavity 111 are provided with sliding holes 112. The bottom of the adjustment cavity 111 is provided with a relief hole 113. The pressure valve 4 extends into the adjustment cavity 111 through the relief hole 113. The top of the adjustment cavity 111 is provided with an adjustment hole 114.
[0024] Locking mechanism 2, see Figure 1 , 2 It includes a handle 21, a first locking plate 22, and a second locking plate 23. The outer ends of the two locking plates are barbed. The handle 21 is rotatably connected to the top of the positioning seat 11. The handle 21 is provided with a toggle lever 211. The toggle lever 211 extends into the adjustment cavity 111 through the adjustment hole 114. The first locking plate 22 and the second locking plate 23 are slidably connected in the sliding hole 112. The first locking plate 22 is provided with a pressure relief plate 221. The pressure relief plate 221 is used to press the pressure valve 4.
[0025] The linkage mechanism 3, located in the adjustment cavity 111, is described in detail below. Figure 1The device includes a linkage gear 31, a first rack 32, and a second rack 33. The linkage gear 31 is rotatably connected to the bottom surface of the adjustment cavity 111. The first rack 32 and the second rack 33 are respectively meshed on both sides of the linkage gear 31. The first rack 32 and the second rack 33 are respectively fixedly connected to the first locking piece 22 and the second locking piece 23. The first rack 32 is provided with a insertion hole 321, and the actuating rod 211 is inserted into the insertion hole 321.
[0026] The locking principle of this product is as follows: When the user rotates the handle 21 from the tilted position to the horizontal position, the actuating lever 211 drives the first rack 32 to slide, and through the linkage gear 31, drives the second rack 33 to slide inward simultaneously. The outer ends of the first locking plate 22 and the second locking plate 23 then hook onto the pot body, thus locking the lid to the pot body. Conversely, when the handle 21 is rotated upward, the actuating lever 211 pushes the first locking plate 22 and the second locking plate 23 outward through the linkage gear 31, thereby releasing the locking state between the lid and the pot body. During the sliding process, if... Figure 4 As shown, the pressure relief plate 221 on the first locking plate 22 can press the pressure valve 4 to ensure that the high-pressure gas inside the pot is completely discharged, making it convenient for the user to separate the pot body from the lid. When using this lid, it can be locked simply by putting it on, making operation more convenient.
[0027] See Figure 1 The first rack 32 and the second rack 33 are respectively provided with positioning pins 34, and the first locking plate 22 and the second locking plate 23 are respectively provided with positioning holes 24. The positioning pins 34 are inserted into the positioning holes 24 to achieve the linkage effect between the rack and the locking plate.
[0028] See Figure 5 The pressure valve 4 includes a valve core 41 and a valve seat 42. The valve core 41 has a through-hole 411, and the valve seat 42 has a connection hole 421. The bottom of the connection hole 421 has several air inlet holes 42212. The valve core 41 is fixed in the connection hole 421. The air outlet 411 has a sealing bead 43 and a spring 44. The spring 44 pushes the sealing bead 43 upward to close the air outlet 411. The top opening of the air outlet 411 has an annular protrusion to prevent the sealing bead 43 from escaping from the top of the air outlet 411. When the sealing bead 43 is pressed down by the pressure relief plate 221, the high-pressure gas in the pot can be discharged outward through the air outlet 411. The top of the regulating chamber 111 has a vent hole 115, which is located directly above the pressure valve 4. The gas discharged through the pressure valve 4 enters the external environment through the vent hole 115.
[0029] See Figure 1Support plates 13 are provided on both sides of the adjustment hole 114. Rotating holes 131 are provided on the support plates 13. A positioning shaft is provided on the handle 21. The positioning shaft is rotatably connected in the rotating hole 131. The handle 21 rotates around the positioning shaft. A relief groove 116 is symmetrically provided on the positioning seat 11. The relief groove 116 is located on both sides of the handle 21. When the handle 21 is in contact with the pot lid, the relief groove 116 makes it easier for the user to lift the handle 21.
[0030] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
