Detailed implementation manners

[0040] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0041] See Figures 1 to 13, in some embodiments of the adjustable pet bowl according to the embodiments of the present utility model, it mainly includes a fixed seat 10 and a bowl body 20, wherein the fixed seat 10 includes a base 11 and a bowl seat 12. In other embodiments, it mainly includes a fixed seat 10 and a bowl body 20, and the fixed seat 10 includes a base 11, a bowl seat 12 and an adjusting ball assembly 13. In still other embodiments, it mainly includes a fixed seat 10, and the fixed seat 10 includes a base 11 and a bowl seat 12 or the fixed seat 10 includes a base 11, a bowl seat 12 and an adjusting ball assembly 13, without including the bowl body 20, and the bowl seat 12 has a downwardly concave inner cavity and the inner cavity is directly implemented as the bowl body 20. It should be noted that the specific structures of the base 11 and the adjusting ball assembly 13 in the above embodiments are the same as those of the base 11 and the adjusting ball assembly 13 in the patent document No. CN117502263A previously applied and published by the applicant, so no specific description and limitation are made in this application. The number of adjusting balls in the adjusting ball assembly 13 is not particularly limited either, and like in the previously applied and published patent document No. CN117502263A by the applicant, it can be zero, one, two, three, etc. The specific adjustment process is also the same, and no description and limitation are made here either. The main improvement of the adjustable pet bowl according to the embodiments of the present utility model lies in the structural improvement at the connection between the bottom of the bowl seat 12 and the base 11 or the adjusting ball assembly 13.

[0042] More specifically, the adjustable pet bowl according to the embodiments of the present utility model, such as Figures 1 to 4As shown, at the bottom of the bowl base 12, there is a connecting part 121 (preferably integrally formed). The connecting part 121 is hemispherical in shape, and a ball hinge assembly 30 is provided on the connecting part 121. The bowl base 12 is connected by matching with the inclined wedge surface in the base 11 (for the convenience of distinction and description, this inclined wedge surface is described as the first inclined wedge surface 320 of 111) on the ball hinge assembly 30 or the matching inclined wedge surface on the adjusting ball assembly 13 (for the convenience of distinction and description, this inclined wedge surface is described as the second inclined wedge surface 132 of 131). The adjustable pet bowl of the present invention also has the effects of multiple use angles of the first use state in which the bowl mouth of the bowl base 12 is horizontal and the second use state in which the bowl mouth of the bowl base 12 is inclined after the bowl base 12 and / or the adjusting ball assembly 13 rotate a predetermined angle relative to the base 11, which the adjustable pet bowl disclosed in CN117502263A has. Moreover, by improving the connection structure at the bottom of the bowl base 12 and adopting a spherical connection structure, the connection structure is more flexible and convenient to rotate and adjust. And compared with the connection structure of the bowl base 12 and the base 11 or the bowl base 12 and the adjusting ball assembly 13 disclosed in CN117502263A, the structural strength is higher, the structural design is more reasonable, and the disassembly and assembly are more convenient. The base 11 and the bowl base 12 or the base 11, the bowl base 12 and the adjusting ball assembly 13 can be separated by disassembling the ball hinge assembly 30, which is convenient for transportation and reduces the volume during transportation. While in CN117502263A, the structure connecting the bottom of the bowl base 12 and the base 11 or the adjusting ball assembly 13 is an integral structure with the bowl base 12. Once this structure is damaged during use or transportation, the entire food bowl cannot be used because this structure may need to rotate during use. Therefore, once damaged, the structural strength will be reduced and it may not be usable. In the present invention, the bowl base 12 and the ball hinge assembly 30 are separately designed. During transportation, the bowl base 12 and the ball hinge assembly 30 are separated. Even if the connecting part 121 at the bottom of the bowl base 12 is slightly damaged during use and / or transportation, as long as it does not affect the connection of the ball hinge assembly 30, it can still be used because the connecting part 121 does not need to rotate during use. What needs to rotate is the second connecting piece 32. That is to say, it will not become unusable due to the reduction of structural strength, and to a certain extent, the use cost is reduced.

[0043] More specifically, as Figure 4As shown, the connecting part 121 of the embodiment of the present utility model is a generally inverted conical structural member with a hollow interior forming an installation cavity and openings at both the upper and lower ends. That is, the end of the connecting part 121 connected to the bottom surface of the bowl base 12 is wider than the end of the connecting part 121 away from the bottom surface of the bowl base 12. For the convenience of description, the opening at the bottom end of the connecting part 121 is described as the first opening, and the opening at the top end is described as the second opening. The second opening penetrates through the bottom surface of the bowl base 12 and communicates with the inner cavity of the bowl base 12 and the top opening of the bowl base 12. This design facilitates the installation of the first connecting member 31 in the installation cavity of the connecting part 121 through the second opening and the removal of the first connecting member 31 from the installation cavity. The ball hinge assembly 30 is composed of three parts, specifically a first connecting member 31, a second connecting member 32, and a fastening member. Both the first connecting member 31 and the second connecting member 32 are in the shape of a bowl dish, and thus can also be described as a butterfly-shaped connecting member. The first connecting member 31 at least partially extends out of the first opening at the bottom of the connecting part 121 to contact the second connecting member 32, so as to facilitate the fastening member to sequentially pass through the second connecting member 32 and the first connecting member 31 to connect the ball hinge assembly 30 with the connecting part 121 of the base 11 into one body.

[0044] More specifically, for the first connecting member 31, as Figure 5 and Figure 6 shown, the first connecting member 31 includes a first body 311, a first convex portion 313, and a second convex portion 312. The shape of the first body 311 is also hemispherical and matches the shape and size of the connecting part 121. The first convex portion 313 is provided at the bottom of the first body 311 and extends outward in the radial direction of the first body 311. The second convex portion 312 extends inward in the radial direction of the first body 311. The first convex portion 313 and the second convex portion 312 are coaxially arranged. The first convex portion 313 and the second convex portion 312 are preferably cylindrical. To facilitate the connection of the fastening member with the first connecting member 31 and the second connecting member 32, axially penetrating first connection holes 315 are opened in the middle of the first convex portion 313 and the second convex portion 312, and the fastening member passes through the first connection holes 315. For the fastening member, in the embodiment of the present utility model, a screw is preferably used. Correspondingly, the first connection holes 315 and the second connection holes 324 are preferably threaded holes.

[0045] For the second connecting member 32, as Figure 7 and Figure 8As shown, the second connecting member 32 includes a second body 321, a first connecting convex portion, and a second connecting convex portion 322. The second body 321 is also hemispherical in shape and matches the shape and size of the connecting portion 121. The first connecting convex portion and the second connecting portion 121 are both formed at one end of the second body 321 facing away from the first connecting member 31, that is, the end connected to the base 11 or the adjusting ball assembly 13. The first connecting convex portion and the second connecting convex portion 322 are coaxially arranged and have different radii. More specifically, the radii gradually decrease from the direction close to the second body 321 to the direction away from the second body 321. More specifically, in the embodiment of the present invention, the second connecting convex portion 322 is farther from the second body 321 than the first connecting convex portion, that is, the radius of the second connecting convex portion 322 is smaller than the radius of the first connecting convex portion. A downwardly concave slot 3211 that matches the first convex portion 313 of the first connecting member 31 is formed on the top surface of the second body 321. Two opposite and downwardly concave positioning grooves 3212 can also be provided on the bottom surface of the slot 3211. The slot 3211 facilitates the insertion of the bottom end of the first convex portion 313, and the positioning grooves 3212 facilitate the docking and positioning of two opposite and downwardly protruding positioning blocks 3121 provided at the bottom end of the first convex portion 313.

[0046] In the embodiment of the present invention, the wedge (for the convenience of description and distinction, the wedge on the ball hinge assembly 30 is described as the first wedge 320, and similarly, the wedge on the adjusting ball assembly 13 is described as the second wedge 132) is arranged on the outer peripheral wall surface of the first connecting convex portion, and the wedge, that is, the first wedge 320, protrudes radially outward along the outer peripheral wall surface of the first connecting convex portion. For the number of the wedges, that is, the first wedge 320, two are preferred. More specifically, the wedge, that is, the first wedge 320, is composed of two parts, as Figure 7 shown, the wedge, that is, the first wedge 320, includes a circumferential wedge portion 3201 that extends circumferentially and obliquely along the outer peripheral wall surface of the first connecting convex portion and an axial wedge portion 3202 that is connected to one end of the circumferential wedge portion 3201 and extends along the axial direction of the first connecting convex portion. The circumferential wedge portion 3201 is more specifically that its upper surface extends obliquely. More specifically, the circumferential wedge portion 3201 extends obliquely upward from the end away from the axial wedge portion 3202 to the end connected to the axial wedge portion 3202. The axial wedge portion 3202 plays a limiting role to limit the rotation angle of two relatively rotating components.

[0047] And for the surface 111 of the first wedge 320, as Figure 9 and Figure 10As shown in the figure, a downwardly recessed first mounting groove is formed on the top surface of the base 11. The first mounting groove is matched with the first connecting convex part. On the inner peripheral wall surface of the notch of the first mounting groove, a first inclined wedge surface 111 that protrudes radially inward and extends circumferentially is provided. The first inclined wedge surface 111 also extends obliquely along the circumferential direction of the inner peripheral wall of the first mounting groove. More specifically, the lower surface of the first inclined wedge surface 111 extends obliquely downward from one end to the other end, and the inclination of the first inclined wedge surface 111 is the same as that of the circumferential inclined wedge part 3201 of the corresponding first inclined wedge 320.

[0048] Further preferably, in order to achieve the firmness of the cooperation between the first inclined wedge 320 and the corresponding first inclined wedge surface 111, as Figure 7 shown, a downwardly recessed groove 3203 is formed on the circumferential inclined wedge part 3201 of the first inclined wedge 320. Correspondingly, as Figure 10 shown, a protrusion 1111 that protrudes downward and is matched with the groove 3203 is provided on the first inclined wedge surface 111.

[0049] When the adjustable pet food bowl of the present utility model includes the adjusting ball assembly 13, the ball hinge assembly 30 is connected to the upper end of the adjusting assembly, and the lower end of the adjusting ball assembly 13 is connected to the base 11. Therefore, for the second inclined wedge surface 131 of the adjusting ball assembly 13, as Figures 11 to 13 shown, a downwardly recessed second mounting groove is formed at one end of the adjusting ball of the adjusting ball assembly 13 where it cooperates with the ball hinge assembly 30. On the inner peripheral wall of the notch of the second mounting groove, a second inclined wedge surface 131 that protrudes radially and extends circumferentially is provided. The structure of the second inclined wedge surface 131 is the same as that of the first inclined wedge surface 111, and no special limitation is made here. Similarly, the lower end of the adjusting ball assembly 13 has a third connecting convex part 323133 that protrudes downward. A wedge, that is, a second inclined wedge 132, which is matched with the first inclined wedge surface 111 on the base 11, is also provided on the third connecting convex part 323133. For the structure of the second inclined wedge 132, it is the same as that of the first inclined wedge 320, so it will not be elaborated here.

[0050] Preferably, as Figure 9 and Figure 10 shown, a first positioning hole 112 is formed in the middle of the bottom surface of the first mounting groove. The first positioning hole 112 corresponds to the second connecting convex part 322 of the ball hinge assembly 30. When the fixing seat 10 includes the bowl seat 12, the base 11 and the adjusting ball assembly 13, as Figure 11As shown, a fourth connecting convex part 134 that protrudes downward and extends and matches the first positioning hole 112 is also provided on the third connecting convex part 323133 at the lower end of the adjusting ball assembly 13. Similarly, a second positioning hole is formed in the middle of the groove bottom surface of the second installation groove, and the second positioning hole corresponds to the second connecting convex part 322 of the ball hinge assembly 30.

[0051] It should be noted that the surface where the notch of the first installation groove of the base 11 is located is an inclined surface. Similarly, the surface where the notch of the second installation groove at the top end of the adjusting ball assembly 13 is located is also an inclined surface, and the bottom surface of the third connecting convex part 323133 at the bottom end of the adjusting ball assembly 13 is also an inclined surface. Moreover, the inclined surfaces at the top and bottom ends of the adjusting ball assembly 13 are arranged intersectingly. Correspondingly, the bottom end surface of the second body 321 of the ball hinge assembly 30 is also an inclined surface. The specific inclination is designed according to the inclination of the first wedge 320 or the surface 111 of the first wedge 320, and no specific description and limitation are made here.

[0052] Preferably, as Figure 5 and Figure 6 shown, two sheet-like convex pieces 314 that extend toward the opening direction of the first body 311 and whose tops are connected to the top of the first body 311 and the sides are connected to the side walls of the first body 311 as a whole are provided at the top end of the second convex part 312 in the first connecting piece 31 more specifically. The setting of the convex pieces 314 can facilitate the taking, installation and disassembly of the first connecting piece 31.

[0053] Preferably, for the adjustable pet food bowl in the embodiment of the present invention, an elastic damping member is further provided between the ball hinge assembly 30 and the connecting part 121. More specifically, as Figure 3 shown, a first annular groove 3111 that recesses inward is provided on the outer peripheral wall surface of the first connecting piece 31, and a first elastic damping member 33 is provided in the first annular groove 3111. The outer peripheral wall of the first elastic damping member 33 fits with the inner wall of the hemispherical connecting piece. More specifically, the outer peripheral wall of the open end of the first body 311 bends outward in an arc, and the first annular groove 3111 is formed on the outer peripheral surface of the arc-shaped bending section formed by the open end of the first body 311. As Figure 3 and Figure 4 shown, a second annular groove 1211 that recesses inward is formed on the outer peripheral wall of the connecting part 121, and a second elastic damping member 34 is provided in the second annular groove 1211. The peripheral wall of the second elastic damping member 34 fits with the inner wall of the second connecting piece 32. The first elastic damping member 33 and the second elastic damping member 34 can be selected as existing conventional rubber rings. This is beneficial to protecting the ball hinge assembly 30 and the hemispherical connecting piece and reducing contact wear.

[0054] It should be understood that the above specific embodiments of the present utility model are only for illustrative explanation or interpretation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model.
