Description

Technical Field

[0001] The utility model relates to the field of kitchen utensils, in particular to a pot cover. Background Art

[0002] A Chinese patent with publication number CN208463726U discloses a pot lid top bead connection structure, which includes a base, a lid, a gasket and a top bead arranged in sequence. A connecting component that can pass through the lid and the gasket and connect to the top bead is protruded at the center of the base. A threaded section is provided at the end of the connecting component, and the top bead component is provided with a threaded hole for the connecting component to be screwed in.

[0003] In the above structure, there is no circumferentially fixed structure between the base, the top ball, and the lid. Therefore, the top ball can still rotate after the three are locked. During the rotation of the top ball alone, it is very likely that the connecting part and the top ball will become loose. If normal use is required, the top ball and the base must be re-tightened to lock them. Therefore, there is still room for improvement in the top ball structure on the existing pot lid. Utility Model Content

[0004] Aiming at the shortcoming that the existing pot cover and the top bead are easily loosened, the purpose of the utility model is to provide a pot cover in which the top bead is not easily loosened after being installed.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A pot cover comprises a base, a pot cover body and a top bead which are arranged in sequence. The base and the top bead can fit together and axially limit the pot cover body. At least two groups of connecting components distributed circumferentially around the base are arranged between the top bead and the base.

[0007] By adopting the above solution, the two sets of connecting components make the top ball and the base form a whole after cooperation, which can play the role of circumferential positioning. When the top ball rotates, the base will rotate with it and will not easily loosen or detach.

[0008] Preferably, a pre-positioning component is provided between the top bead and the base to enable the connecting component to be quickly aligned.

[0009] Preferably, the pre-positioning component includes a key protruding from the top ball, and a positioning groove for inserting the key is provided on the base.

[0010] By adopting the above solution, the key and the positioning groove can be used to align the top bead with the installation position of the connecting component when it is fitted to the base, which facilitates the subsequent installation of the connecting component.

[0011] Preferably, a limiting groove is provided on the pot cover body, and the key is engaged with the limiting groove and the positioning groove at the same time.

[0012] With the above solution, the key in this solution plays a role of pre-positioning before installation, and after installation is completed, it can also play a role of limiting the circumferential rotation of the pot cover body, further optimizing the feel of the pot cover.

[0013] Preferably, the key and the top ball are detachably connected, the key is integrally provided on a connecting piece, and the top ball is provided with a mounting groove for guiding the insertion of the connecting piece.

[0014] With the above solution, the key cooperates with the limit groove to transmit torque while limiting the position, so that the pot cover body and the top ball rotate synchronously. If the key and the top ball are integrated, the root of the key will be subjected to stress when bearing torque. After long-term use, the key will easily break from the top ball, resulting in failure of the circumferential limit. In this solution, the torque of the pot cover and the top ball is shared by the key and the connecting part, and the two are designed as one, so they are not easy to break and fail.

[0015] Preferably, the key and the positioning groove are tightly fitted.

[0016] With the above solution, when the key is inserted into the positioning slot, the two are tightly matched to form a certain friction force to limit the movement of the base, which can better perform pre-positioning.

[0017] Preferably, bosses are provided on the opposite end faces of the top bead and the base. When the top bead and the base are matched, the end faces of the two bosses fit together, and the side faces and step surfaces of the two bosses cooperate to form an annular groove for axially limiting the pot cover body.

[0018] Preferably, the connecting assembly includes a bolt, a through hole for the bolt to pass through is provided on the boss of the base, and a threaded hole for the bolt to be screwed and fixed is provided on the boss of the top ball.

[0019] Due to the adoption of the above technical solution, the utility model has significant technical effects: the two sets of connecting components make the top ball and the base form a whole after cooperation, which can play a role in circumferential positioning. When the top ball rotates, the base will rotate with it and is not easy to loosen or detach. In addition, the top ball in the utility model can align the installation position of the connecting component when the top ball and the base are in contact through the cooperation of the key and the positioning groove, which facilitates the subsequent installation of the connecting component.

[0027] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0028] Example

[0029] A pot cover, according to Figure 1 、 3 As shown, it includes a base 1, a pot cover 2 and a top ball 3 arranged in sequence. The base 1 and the top ball 3 can fit each other and axially limit the pot cover 2. Figure 3 、 6 As shown, in this embodiment, bosses 9 are relatively protruded on the two end faces of the top ball 3 and the base 1. When the top ball 3 is matched with the base 1, the end faces of the two bosses 9 fit together. The side faces of the two bosses 9 and the step surfaces formed therefrom cooperate to form an annular groove 10 that can limit the axial movement of the pot cover body 2. At least two groups of connecting components distributed circumferentially around the base 1 are provided between the top ball 3 and the base 1. Figure 6 As shown, in this embodiment, two groups of connecting components are provided, and the connecting components include bolts 11, a through hole 12 for the bolts 11 to pass through is provided on the boss 9 of the base 1, and a threaded hole 13 for the bolts 11 to be screwed and fixed is provided on the boss 9 of the top ball 3.

[0030] A pre-positioning component is provided between the top ball 3 and the base 1 to enable the connection component to be quickly aligned. Figure 3 、 4 As shown, the pre-positioning component includes a key 4 protruding from the top ball 3, a positioning groove 5 for inserting the key 4 is provided on the base 1, a limiting groove 8 is provided on the pot cover body 2, and the key 4 is simultaneously engaged with the limiting groove 8 and the positioning groove 5. In this embodiment, the key 4 and the top ball 3 are detachably connected, the key 4 is integrally arranged on a connecting member 6, and a mounting groove 7 for guiding the insertion of the connecting member 6 is provided on the top ball 3, and the key 4 and the positioning groove 5 are tightly fitted.

[0031] Combined with the above structure, reference Figures 1 to 6It can be seen that the pot lid of this embodiment has two sets of connecting components so that the top ball 3 and the base 1 form a whole after being matched, which can play a role in circumferential positioning. When the top ball 3 rotates, the base 1 rotates with it and is not easy to loosen or detach.

[0032] By cooperating with the key 4 and the positioning groove 5, the top ball 3 can be aligned with the installation position of the connecting component when it is fitted with the base 1, so that the top ball 3 and the base 1 can be pre-positioned before installation, which is convenient for the subsequent installation of the connecting component. After the installation is completed, the key 4 can also limit the circumferential rotation of the pot cover body 2 relative to the top ball 3, further optimizing the feel of the pot cover.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
