Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a water tank hinge. Background Technology

[0002] Modern coffee machines and desktop water dispensers are equipped with removable water tanks for easy use and cleaning. The water tank typically consists of a body and a lid, with the lid opening and closing onto the body. There are generally two installation methods for the lid and body: a separate connection and a hinged connection. Both methods have problems. A separate connection can easily lead to the lid being lost or inconvenient to operate, or the lid may fall into the tank during operation. With a hinged connection, the lid's shape and dimensions must be considered after installation to ensure harmony with the machine's appearance and ease of operation; the lid's position cannot be arbitrary to avoid interference during opening and closing. Furthermore, current lid-body connection structures on the market are relatively complex, with many parts and inconvenient operation. Utility Model Content

[0003] The purpose of this utility model is to design a water tank hinge to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model designs a water tank hinge, including a cover, a tank body and a hinge seat. The hinge seat is installed on the edge of the opening of the tank body through an insertion part. The upper part of the hinge seat is provided with an elongated mounting hole. The cover body is provided with a shaft. The elongated mounting hole is arranged horizontally or inclined relative to the hinge seat. The cover body is inserted into the elongated mounting hole through the shaft to form a detachable rotatable connection with the hinge seat.

[0005] The shaft can float radially within the elongated mounting hole. When the shaft floats to the first end of the elongated mounting hole, the cover closes at the opening of the box.

[0006] When the shaft floats to the second end of the elongated mounting hole, the cover flips away from the box opening and is in an inclined or vertical state.

[0007] Preferably, from a longitudinal section perspective, the elongated mounting hole is shaped like a long waist hole and is inclined vertically toward the center of the box. The angle between the elongated mounting hole and the horizontal plane of the box opening is an acute angle.

[0008] Further optimization involves making the outer diameter of the shaft smaller than the width and length of the elongated mounting hole, so that the shaft can float along the length and width of the elongated mounting hole after being inserted into it.

[0009] Further optimization involves having two elongated mounting holes, located on opposite sides of the hinge seat. One end of each elongated mounting hole forms an opening for inserting a shaft. The hinge seat has a notch that communicates with both the opening and the elongated mounting hole. The shaft and the elongated mounting hole are arranged in a one-to-one correspondence.

[0010] Further optimization involves the hinge seat having an integral seat body with a slot formed to create an elongated mounting hole. After the elongated mounting hole is formed, the seat body partially forms a deformable thin plate structure. The notch is formed in the thin plate structure and located below the top of the elongated mounting hole, and the width of the notch is smaller than the outer diameter of the shaft body.

[0011] Further optimization involves providing two opposing mounting seats on the cover, which are integrally connected to the cover, with shafts extending from the opposing surfaces of the two mounting seats.

[0012] Further optimization involves providing a protrusion on the hinge seat or seat body. When the cover is opened to a predetermined angle position relative to the box body, the mounting seat of the cover abuts against the protrusion, thereby positioning the cover at the predetermined angle position.

[0013] Preferably, the insertion part includes a slot formed on the hinge seat, and the peripheral wall of the housing is provided with a plate that forms an insertion fit with the slot, and the plate and the peripheral wall of the housing are integrally connected.

[0014] Further optimization includes a snap-fit ​​structure, which includes a groove on the hinge seat, a deformable locking tongue extending from the inner wall of the groove, and a positioning groove on the plate that engages with the locking tongue in a snap-fit ​​manner.

[0015] Further optimization involves the buckle structure being positioned so that it corresponds one-to-one with the base and is close to it.

[0016] The technical advantages of this utility model are as follows: the box body and the cover body are connected by a hinge seat, which is connected to the box body by a plug-in method. The hinge seat has an elongated mounting hole, and the cover body is rotatably connected by inserting a shaft into the elongated mounting hole, realizing the opening and closing of the cover body. The box body, cover body, and hinge seat form a detachable assembly, which is not only simple in structure, but also adaptable to different sizes and models of box bodies and covers by adjusting the size of the hinge seat, thus having good versatility. The elongated mounting hole is a long, oblong hole with an inclined setting, which allows the shaft to float inside, so that the cover body can rotate and move backward at the same time, thus avoiding interference with the equipment. When the cover body is opened or closed to 90 degrees, it can be used as a handle, which is very convenient and does not affect the structure of the cover body, while also taking into account the aesthetic appearance.

[0026] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0027] This utility model includes a cover 1, a box 2, and a hinge seat 3. The hinge seat 3 is installed on the edge of the opening of the box 2. The lower part of the hinge seat 3 is provided with a plug part 4. The hinge seat 3 is plugged into the edge of the opening of the box 2 through the plug part 4. The plug part 4 also includes a snap-fit ​​structure. After the hinge seat 3 is plugged into the box 2, the hinge seat 3 forms a snap-fit ​​connection with the peripheral wall of the box 2 through the snap-fit ​​structure, thereby making the hinge seat 3 and the box 2 detachably connected. The upper part of the hinge seat 3 is provided with two opposite elongated mounting holes 5. The cover 1 is provided with a shaft 6. The shaft 6 is arranged one-to-one with the elongated mounting holes 5. The shaft 6 is plugged into the elongated mounting holes 5, so that the cover 1 and the hinge seat 3 form a detachable rotatable connection, thereby realizing the opening and closing of the cover 1 relative to the hinge seat, and thus realizing the opening and closing of the cover 1 relative to the box 2.

[0028] In this embodiment, the hinge seat 3 is provided with two opposing seat bodies 9 integrally formed with the hinge seat 3. Each seat body 9 is slotted to form an elongated mounting hole 5, thereby forming two opposing elongated mounting holes 5. The two elongated mounting holes 5 are located on both sides of the hinge seat 3. One end of the two elongated mounting holes 5 forms an open end 7 for inserting the shaft body 6. The hinge seat 3 is provided with a notch 8 that communicates with the open end 7 and the elongated mounting hole 5. The notch 8 extends axially along the elongated mounting hole 5. It should be noted that after the seat body 9 is provided with the elongated mounting hole 5, a part of the seat body 9, that is, the part where the elongated mounting hole 5 is located, becomes a deformable thin plate structure, so that the shaft body 6 can be installed and removed from the notch 8, realizing that the shaft body 6 can be detachably connected to the elongated mounting hole 5. This not only has a simple structure, but also a stable connection.

[0029] Furthermore, from a longitudinal section perspective, the elongated mounting hole 5 is shaped like a long, narrow hole. This long, narrow hole is vertically inclined towards the center of the housing 2 relative to the hinge seat 3. The angle between the elongated mounting hole 5 and the horizontal plane of the opening of the housing 2 is α, where α is an acute angle, typically set below 60 degrees. This ensures the optimal inclination of the long, narrow hole. When the cover 1 opens and closes around the elongated mounting hole 5, the cover 1 can simultaneously move horizontally backward. In other words, the cover 1 rotates while moving backward, preventing interference between the bottom of the cover 1 and the coffee or water dispenser equipment. Since the housing 2 is usually located inside or to the side of the equipment, this design optimizes space utilization. For aesthetic and harmonious design, the cover 1 is flush with the equipment when closed. If the elongated mounting hole 5 is not inclined (i.e., horizontal or vertical), the bottom of the cover 1 will interfere with the equipment during opening, closing, or flipping. The inclined mounting hole 5 avoids this, making the opening and closing of the cover 1 smoother and more comfortable, without affecting the positional relationship between the cover 1 and the equipment. This balances the feel of opening and closing the cover 1 with the overall appearance. At the same time, when the cover 1 is used as a handle, the shaft is positioned at the top of the inclined elongated mounting hole, providing a certain positioning and preventing the cover 1 from shifting or sliding.

[0030] In addition, the elongated mounting hole 5 can also be set horizontally, that is, the included angle α between the horizontal planes of the opening of the housing 2 is 0 degrees. In this way, the shaft 6 can also float in the elongated mounting hole 5, and the cover 1 can also move horizontally backward to avoid interference with the coffee machine or water dispenser.

[0031] It should be emphasized that the shaft 6 can float radially within the elongated mounting hole 5. When the shaft 6 floats to the first end of the elongated mounting hole 5, that is, the bottom end of the elongated mounting hole 5, the cover 1 closes onto the opening of the box 2. When the shaft 6 floats to the second end of the elongated mounting hole 5, that is, the top end of the elongated mounting hole 5, the cover 1 flips away from the opening of the box 2 and is in an inclined or vertical state. At this time, the cover 1 can be used as a handle.

[0032] Furthermore, the outer diameter of the shaft 6 is smaller than the width and length of the elongated mounting hole 5. The shaft 6 is a cylindrical pin structure, and its outer diameter is smaller than the width and length of the elongated mounting hole 5. In this way, after the shaft 6 is inserted into the elongated mounting hole 5, it can float along the length and width of the elongated mounting hole 5, that is, it can move up and down and back and forth along the radial direction of the elongated mounting hole 5.

[0033] It should be noted that, for ease of description, the width and length of the elongated mounting hole 5 are described from a longitudinal section perspective; please refer to [reference needed]. Figure 7 and Figure 8 The section view of the elongated mounting hole 5.

[0034] Furthermore, the notch 8 is opened in the thin plate structure and located below the top of the elongated mounting hole 5, and the width of the notch 8 is smaller than the outer diameter of the shaft 6. This can prevent the shaft 6 from detaching from the elongated mounting hole 5 through the notch 8 during the floating process. At the same time, when the cover 1 is rotated 90 degrees relative to the box 2, the cover 1 can be used as a handle. At this time, the shaft 6 of the cover 1 will abut against the top of the elongated mounting hole 5, and the notch 8 is located below the top of the elongated mounting hole 5. In this way, even if the weight of the box 2 is too heavy, the base 9 will not deform and cause the shaft 6 to detach from the notch 8.

[0035] Furthermore, the cover 1 is provided with two opposing mounting seats 10. The mounting seats 10 are integrally connected to the cover 1 or extend from the cover 1. A shaft 6 extends from the opposing surfaces of the two mounting seats 10 to ensure the strength of the shaft 6, thereby ensuring the stability of the cover 1 when used as a handle.

[0036] Furthermore, the hinge seat 3 or the seat body 9 is provided with a protrusion 11. In this embodiment, the seat body 9 extends partially toward the center of the box body 2, and the protrusion 11 extends outward from the partially extended surface. When the cover 1 is opened relative to the box body 2 to a predetermined angle position, in this embodiment, the predetermined position is that the cover 1 is opened relative to the box body 2 to an angle of approximately 90 degrees. The mounting seat 10 of the cover 1 just abuts against the protrusion 11, so that the cover 1 is positioned at this angle position, which is convenient for cleaning the box body 2 and changing the water.

[0037] Furthermore, the insertion part 4 includes a slot 12 formed on the hinge seat 3. In this embodiment, the hinge seat 3 is a straight plate structure. The bottom of the hinge seat 3 has a groove that runs through both ends, which is the slot 12. The peripheral wall of the box body 2 is provided with a straight plate 13. The plate 13 and the peripheral wall of the box body 2 are integral. The plate 13 and the slot 12 form an insertion fit, thereby realizing that the hinge seat 3 is inserted into the peripheral wall at the opening of the box body 2.

[0038] Furthermore, the insertion part 4 also includes a snap-fit ​​structure, which includes a groove 14 formed on the hinge seat 3. The groove 14 has the surface of the hinge seat 3. A deformable plate extends from the inner wall of the groove 14. The plate forms a protrusion on the side facing the plate 13, thus serving as a locking tongue 15. A positioning groove 16 is formed on the plate 13. When the slot 12 and the plate 13 are inserted and engaged, the locking tongue 15 is inserted into the positioning groove 16 to form a snap-fit ​​engagement, thereby achieving the stability of the connection between the hinge seat 3 and the housing 2, while not affecting the removal of the hinge seat 3 from the housing 2.

[0039] In this embodiment, the buckle structure corresponds one-to-one with the base 9 and is arranged close to each other, that is, there are two buckle structures located between the two bases 9. This ensures the stability of the buckle connection, so that the cover 1 can also be stable and safe as a handle.

[0040] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
